Investigation report on assembly line production practice in electronics factory?
Assembly line production in electronic factory is a form of production organization. It divides the production process into several processes with equal proportion or multiple proportion in time, and fixes them on three stations arranged in sequence according to the process flow, and the work object flows through each station in turn for processing at a certain rhythm or speed. This production method uses common equipment, so that each task on the production line has a stable time, and according to the order of processing procedures, the products quickly "flow" from one procedure to the next. Through the control system, the product productivity is consistent with the utilization rate on the final assembly line. ?
In summer vacation, in order to increase social experience, improve practical ability, increase tuition income and enrich holiday life, I used the holiday to enter an electronics factory and worked as a blue foreman for 40 days. I was deeply touched by the production mode of the electronics factory and learned a lot from my own experience. ?
The factory where I work is divided into several major departments, such as management department, finance department, manufacturing department, personnel department, logistics department and security department. And the division of labor among all departments is clear, which ensures the benign operation of the whole company. Because I am a short-term worker and have no education, I can only interview the assembly line of manufacturing department to make front frame, back shell, base, keyboard, mouse and so on. All kinds of computers. A production line is a whole, and it needs team cooperation. If anything goes wrong in any process, I can't produce qualified products At first, I was a novice in the processing workshop and could not adapt to the linear speed of nearly 900R/MIN on the assembly line. I'm afraid I can't keep up with the products at the end of the production line. After nearly half a month's running-in, I feel that I have adapted to all kinds of work on the assembly line (except full inspection, and I can only pass at least two years' work experience), from casting line, printing, pre-inspection, sticking protective film, sticking Myra, screwing, hot melting, pressing and packing. Now we can not only keep up with the linear speed of 900R/MIN, but also challenge the linear speed of 1200R/MIN. ?
After I completed the adaptation in the first half of the month, I also got a better understanding of the composition and functions of the manufacturing department. The manufacturing part consists of four workshops: molding workshop, processing workshop, dust-free workshop and precision workshop. In the molding workshop, raw materials are mainly added to the molding machine to make the simplest semi-finished products, which are then simply packaged and sent to the processing workshop for secondary processing. After processing in the processing workshop, some products can be sent to foreign factories, and the other part can be sent to the dust-free workshop for simple assembly. The last step is to go to the precision workshop for final processing and assembly, and then the finished computer is built. Then it is transported to major shopping malls by the company's special car, and then those electronic products enter the hands of our consumers. ?
Of course, what I am most familiar with is the processing workshop, which is mainly used to insert various front frames and back shells.
Simple processing, such as sticking protective film on the front frame, sticking Myra, installing keys and hot pressing. . . Or put a hot iron sheet on the back shell, stick a protective film, or stick a foot pad, screws, packaging, etc. In the base. The specific process can be summarized as follows:
Threading-printing-pre-inspection-assembling parts (pasting protective film, pasting Myra, pasting foot pads, tightening, assembling, installing keys, etc.). )-Full inspection-Packaging and sealing?
Through a period of work observation, I found that our workshop really can. First of all, there is such a clear safety goal: 1, work safety, employee safety. 2, no pollution, no harm, no harm. 3. Employees feel at ease, and so does the boss. 4. Strive to create a safe and worry-free workplace. Secondly, every employee is required to achieve 5S. This is the most basic assembly line. ?
1, finishing) 2, cleaning) 3, checking) 4, paying attention to 5, safety?
Production workshops can be divided into three categories: 1 first-class workplace, where no one litters and some people clean. In a second-rate workplace, some people litter and some people clean. In the third-rate workplace, some people litter and no one cleans up. Only by striving for a first-class workshop can we achieve the expected results, that is, increasing output, improving quality, reducing costs, strictly observing delivery time, ensuring safety and obtaining considerable benefits. ?
Through nearly forty days' work, I have a comprehensive understanding of the rules and regulations of workshop attendance. When front-line employees go to work, they go to the workshop to see their arranged lines and work, gather at the designated place, and wait in line for the line leader and foreman to explain the operation points before going online. After arriving at the production line, read the production instruction manual (SOP) on your post first, and ask the line leader if you have any questions. Don't chat with other operators. There are also many specifications for front-line employees to go offline. In the case of wiring, employees in each position need to hand over the problems encountered in the operation to the next operator. Register and fill in your used materials, and take the initiative to hand them over to the materials clerk for checking. Before leaving the production line, clean up the 5S in the workplace. After meeting at the designated place, leave the workshop at eight o'clock on time. ?
The production idea of assembly line is: the previous process serves the next process, and the latter process checks the previous process. Check the previous products and do this process well. There is also printing. There must be no deviation in fonts and letters, and there are defects such as hairiness, bottom leakage, ghosting, hyphenation, ink leakage and static electricity. When assembling parts, check whether the products are defective, such as deformation, lack of materials, dirt, broken columns, broken ditches, etc. Assemble the accessories to the corresponding position of the product, and avoid abnormal situations such as wrong assembly, missing assembly and reverse assembly. Carefully remove the product after hot melting. The hot melting point of columnar appearance should not be high or offset, nor should it be squeezed to the periphery of the product. The locking screw cannot adjust the torque of the electric screwdriver alone. The circle on the torque screwdriver must exactly match the kilograms marked on the circle. If adjustment is needed, press the emergency bell to find the public works. When the packaged products are placed on the tray, they should be put down gently, neatly packed and labeled externally. ?
It is precisely because of a relatively sound assembly line production system that the company can operate normally. But after working for a month, I feel that the assembly line has further increased the labor intensity of workers, because the work density is high and the intensity is high, but it is indeed an efficient production method. ?
Because labor units don't have to move, assembly line production efficiency is high, and large-scale mass production is possible. At the same time, because the production unit only partially processes the labor object and does not need to be responsible for the labor object as before, the workers' technology is further specialized. ?
The assembly line strengthens the demand for division of labor, which can promote labor productivity for the following reasons: first, the skills of workers are improved because of their majors; ?
Second, it takes a lot of time to transfer from one major to another, and the division of labor can avoid time loss; Third, mechanical inventions that simplify and shorten labor can realize division of labor on the basis of division of labor.
It precedes the assembly line, which promotes the division of labor and makes it more thorough; ?
Everyone's speed on the assembly line is changing, sometimes fast and sometimes slow, but the ability to do it faster than the average speed is limited. The speed of work must depend on the speed of the front team, which can't be synchronized and achieve the traditional balance, but its production efficiency is beyond doubt.
