This week's training gave me a little understanding of the real life and the electricity in the production workshop, which allowed me to get a workout, to consolidate my previous knowledge, improve my hands-on ability, and cultivate hands-on cooperation between groups. Ability.

The ten-day electrician training was intense and orderly, which gave us an internship experience in the workshop. This training is a sequential simulation test under actual conditions. The voltage used is 220 volts to 380 volts, so the requirements for us are very high. If there is a risk of electric shock, there is a burning instrument. Before the training begins. The teacher told us that safety is first and can't be sloppy. When you turn on the power, you should check it again. You should also inform other people to avoid electric shock. The teacher also talked about the problems that should be paid attention to during the test. Then we started the experiment according to the good group. .

I just started to do a week of training, thinking that I have to do a lot of experiments, and I have only four materials. I have four tests in this electrician training. The first test is a home power supply line training. The main purpose is to learn the fluorescent lamp circuit. , one lamp and two ground control, light adjustable circuit, sound and light delay circuit, correct connection of the file control circuit. In the past, I knew about the domestic power supply line, only the fire line and the zero line. The connection of some switches, and the actual life of electricity is a dangerous thing, not touching at home, so I don’t know much. Through the teacher's explanation, we have a certain understanding, we received very smoothly, the sound and light delay switch must be wrapped with things to make the light bulb bright. Through this training, I have a certain understanding of home points.

The second test is the anti-turn-turn training of the motor. We have a certain theoretical knowledge in the last semester. I think there should be no problem. I can do it. I can do it one thing. After the motor is not turned, I found that it is The touch points cannot kiss and. After we change the voltage, the circuit resumes normal operation and the motor starts to reverse-forward. This makes me understand that the wiring must be serious and not sloppy. Everything must be done seriously. I feel a lot.

The third test motor can be both jog and self-locking control line training. This test circuit has not been checked with the previous one. In addition, we have already done two tests, and we have some familiarity with the application of electrical appliances. The operation is relatively smooth, I have learned a lot, let me have a new understanding of the motor, and can smoothly regulate.

The last test is the automatic round-trip circuit training of the workbench. We need to master the method of transforming the electrical schematic into the installation wiring diagram through the actual installation wiring, and master the function of the travel switch and the application of the machine tool circuit. This test is very complicated. We take the line and open the switch. The machine can't move. We check the line and find that there is no connection in one place. We connect the line and the tool is maneuvered. Although it is not the same as the test requirements, we are very happy, because it moved, we have checked the line several times, no problems, we are very anxious, adjust the high frequency to the low frequency, or not, finally we put 1, 2 3, 4 They changed, the tool was maneuvered, and we succeeded.

The one-week internship ended in an instant, but a fiery heart was still reluctant in the internship venue, especially for our instructors.

Through a few days of internship, I have learned a lot of truths. It is really "beneficial". This time, our internship task, although not very heavy, is to install some simple lighting circuits according to the picture. The principle is not very complicated, but it really takes a lot of effort to install it. Because it is the four students sharing a station, the most important thing is the spirit of cooperation between the two sides. I have the deepest experience.

Work is carried out in an orderly manner, and this work requires special care. If you don't get it, it's easy to get everything you do all over again. First of all, it is necessary to check the installed equipment to check whether it is in good condition. Once again, it is necessary to use the skillful force to put each pair of clips on and on. It is exhausted after one afternoon, but it is very gratifying to see the effect of the installation. In another year and a half, we will step into the society and set foot on our own jobs, but I feel that the week of study is a portrayal of future life. I will use my book knowledge and practical ability to support it. The sails in the river...

The first time I watched the motor turn around by myself, the feeling was proud. I will say in my heart: "Hey, I can also turn the motor up, ha, happy. Come on, in fact, this is quite fun."

Our teachers always tell us some theoretical content, and then we are ready to let us wiring. At the beginning of the wiring, we followed the map and there was no order at all, so the line that was connected was like a spider web. I think it’s funny now.

Also, because of the electrician class, we have learned a lot of common sense that we don't usually pay attention to, such as safety electricity common sense, electrician basic operation, electric lighting; some commonly used low-voltage electrical appliances; usage of the stroke switch; motor structure and nameplate Meaning; control circuit failure analysis and elimination. Well, in short, I still feel a lot of things I have learned. The four electrician opponents personally realized the importance of the overall thinking. To lay a good board, we must have a whole logical thinking. The layout should pay attention to the space arrangement of each component and also notice that the wiring and the line cannot intersect. And note

Through this week's training in electronic and electrical engineering, we have also cultivated our courageous, careful, and cautious work style. Since the first three trainings are completed by connecting the daily low-voltage circuit, it is necessary to pay attention to the safety of electricity. It is not allowed to touch the different parts of the electrical components and the rotating parts of the motor by hand. It is also required to be careful and cautious when operating, to avoid electric shock and accidental injury. In the following several trainings, the electric iron was used. It is also the requirement for students to master the correct use of the electric money. Through this one-week electrician training, I really learned a lot of knowledge and expanded my horizons. Through this electrician training, I have enhanced my ability to do hands-on operation. I remember when I was in high school, I installed a switch control circuit for my family, and I avoided accidental injuries because of my own hands. The ability is not strong enough, and the result is that the circuit is short-circuited. Fortunately, because the circuit was originally equipped with a fuse, there is no big safety accident. Through this electrician training, I mastered the installation of the fluorescent lamp circuit and learned the control methods of the two places of the incandescent lamp. I also learned some low-voltage electrical appliances and learned about their specifications, models and methods of use. More importantly, I also learned how to wire and check the circuit.

Through this training of electricians, we have also cultivated our standard work style and our team spirit of unity and cooperation.

Sixth, the feeling of welding internship: One of the most challenging training in my hands during the one-week internship is welding. Welding is one of the basic methods of metal processing. The basic operation of the "five-step method" - preparing welding, heating the weldment, melting the solder, removing the solder, removing the soldering iron - seems easy, but it takes a long time to master. The solder joints at the beginning can only be described by the words “ugly and ugly”, but the welding assessment forced us to complete the assessment target in just one day. It can be said that there must be a qualitative leap. So I endured my mind, arrogant and arrogant, and slowly came. In the process of constantly challenging myself, my hand holding the soldering iron does not shake, and the hand that sends the solder can basically master the dosage, and the welding technology is becoming more and more mature. When I finally managed to complete a qualified solder joint in the shortest amount of time, the fear of soldering had long since dissipated, and I was replaced by confidence in my ability to do it. In the process, I feel deeply that it may seem simple, but it may not be the case. In the process of welding internship, I learned a lot of things that I didn't know before. For example, I only know that there is a soldering iron before the internship. I don't know that there are many kinds of them. There are single-use, dual-use, and temperature-regulating. There are so many types of thermostatic, direct heating, inductive, internal and external heating. Also, you can't use rosin to wipe the soldering iron before hanging the tin, which will speed up its corrosion and reduce air pollution, and so on. However, I also encountered a lot of things that I don't understand. 1. Why do you want to hang the solder on the solder to prevent oxidation? As long as I clean the surface of the soldered component, I don't understand it. After the soldering iron is completely heated, whether it is first coated with flux or first with tin, I use the latter, some people use the former. They are all welded out, but I often get a situation of welding in the process of welding, and the latter is not to speed up its corrosion and reduce air pollution, I don't understand. Seven, the experience of the design of the printed circuit board diagram internship welding challenges I have the ability to work, then the design of the printed circuit board diagram is to challenge my ability to quickly accept new knowledge. Under the premise that I have never touched the printed circuit board diagram in the past, it is a great challenge for me to use one afternoon to accept and digest the contents of the teacher. In this process, I mainly exercised the spirit of teamwork, discussion and common progress with me and other students. Because I am not very clear about circuit knowledge, it can be said to be vague. But when I have something to understand, I will ask other students, even if they are busy thinking, they will stop to help me and eliminate my blind spots. When I have any idea to tell them, they will not accept my advice because I have no idea. In the whole process of this internship, although I was only a supporting role, I deeply felt the true meaning of friendship between my classmates. During the internship, I was familiar with the process flow of the printed circuit board and the experience of designing the eight- and six-tube superheterodyne radio assembly and commissioning internship. For me, this is undoubtedly a new learning, a challenge. I also learned a lot of useful knowledge. This internship is my most interesting internship and my most failed internship. I liked to assemble and disassemble from an early age, but this time I failed once, although the second time I succeeded, but after all, I had more internships than others. Summarizing this internship, I feel that I am sometimes very careless and unconfident. At the beginning, I got the radio to be good, but I always didn't ring when I tested. I asked my classmates to know that I didn't open the switch. Open the switch and go to check it. Before the inspection, I tested it again with great confidence. This will break the wire connected to the speaker, and then re-weld the speaker on the street. The screwdriver accidentally dropped the speaker. . As the saying goes, the disaster is not alone, then the SP1 joint is broken, and the copper foil at the weld is melted. Had to be void. Hey. In this internship, I understand the importance of self-confidence. But I also understand that my hands-on ability is still very inadequate, lack of exercise, in this case can not be qualified for future work, so in the future learning process, I should work hard to unite the theory and practice, focusing on exercising their own Hands-on ability is to have a certain strength when facing the future work.

IX. Summary In general, I am enthusiastic about this course. First, I was very interested in this kind of small production since I was a child. I didn't know how to weld at the time, but I liked to put things apart, but in this case, this thing was abolished. Now the electrical and electronic practice class is learning how to put things back. Every time I complete a step, I am as happy as a child and have a sense of accomplishment. Second, the electrical and electronic internship is characterized by the students themselves, mastering certain operational skills and personally designing, making, assembling and debugging. It combines basic skills training, basic process knowledge and innovation enlightenment to cultivate our practical ability and innovative spirit. As a university student in the information age, it is not enough to operate a mouse as a high-skilled talent that is cultivated by the state. The basic hands-on ability is the basis and necessary condition for all work and creation.

After a week of study, I feel that I have gained in the following aspects:

First, there is a preliminary systematic understanding of the theory of electronic processes. We learned the techniques of soldering common components and circuit components, the design and fabrication of printed circuit board diagrams, the working principle of radios, and the role of components. This knowledge is not only effective in the classroom, but also has great guiding significance for the future study of electronic technology courses. It has practical significance in daily life.

Second, it is a great exercise for your own hands-on ability. Practice knows the truth, and all the inventions and creations are tested in practice. Without sufficient hands-on ability, it is extravagant to make achievements in future research, especially experimental research. During my internship, I exercised my own hands-on skills and improved my ability to solve problems. For example, when the radio was assembled and debugged, the spacing of several pads was extremely small, and they were welded together with a little carelessness, but I still completed the task.

6. The feeling of welding internship:

One of the most challenging exercises in my internship during the week was welding. Welding is one of the basic methods of metal processing. The basic operation of the "five-step method"?? Prepare to weld, heat the weldment, melt the solder, remove the solder, remove the soldering iron?? It seems easy, but it takes a long time to practice.

They are all welded out, but I often get a situation of welding in the process of welding, and the latter is not to speed up its corrosion and reduce air pollution, I don't understand.

7. Experience of design internship on printed circuit board diagram

The welding challenge I have to do, then the printed circuit board design is challenging my ability to quickly accept new knowledge. Under the premise that I have never touched the printed circuit board diagram in the past, it is a great challenge for me to use one afternoon to accept and digest the contents of the teacher. In this process, I mainly exercised the spirit of teamwork, discussion and common progress with me and other students. Because I am not very clear about circuit knowledge, it can be said to be vague. But when I have something to understand, I will ask other students, even if they are busy thinking, they will stop to help me and eliminate my blind spots.

In the whole process of this internship, although I was only a supporting role, I deeply felt the true meaning of friendship between my classmates. During the internship, I was familiar with the process flow, design steps and methods of printed circuit boards. However, I have not been able to independently complete the design of the printed circuit board diagram. It is a pity. This internship forced me to believe that my knowledge is still not perfect and that the design ability needs to be improved.

Eight. Six tube superheterodyne radio assembly and commissioning experience

For me, this is undoubtedly a new study. It is both a challenge and a lot of useful knowledge. This internship is my most interesting internship and my most failed internship. I liked to assemble and disassemble from an early age, but this time I failed once, although the second time I succeeded, but after all, I had more internships than others. Summarizing this internship, I feel that I am sometimes very careless and unconfident. At the beginning, I got the radio to be good, but I always didn't ring when I tested.
