Technology and production of car harness

With the continuous improvement of people's requirements for comfort, economy and safety, the types of electronic products on the automobile are also increasing, and the failure rate of the automobile wiring harness is increasing correspondingly. This requires to improve the reliability and durability of the car harness performance, many people are interested in the process and production of the car harness, here Yuanpeng electronics on the car harness process and production of this knowledge to do a simple description, you only need to spend a few minutes to read, you can roughly understand.
After the two-dimensional product drawings of automobile wiring harnesses are produced, the production process of wiring harnesses should be arranged. Technology is inseparable from production. Therefore, the author combines the production and technology of automobile wiring harnesses together for analysis.
The first station of harness production is the open wire process. The accuracy of the opening process is directly related to the entire production schedule. Once there is an error, especially if the opening size is too short, it will lead to the rework of all stations, which will affect the production efficiency. Therefore, it is necessary to reasonably determine the wiring size and stripping head size of the wire according to the requirements of the drawings in the preparation of the wiring process.
The second station after opening the wire is the crimping process. Determine the crimping parameters according to the terminal type required by the drawings, and make the crimping operation manual. For those with special requirements, indicate on the process document and train the operators. For example, some wires need to pass through the sheath before they can be crimped, it needs to be pre-installed wire and then return from the pre-installed station and crimped; There are also puncture type crimping used in special crimping tools, this crimping mode has good electrical contact performance.
Then is the preassembly process, the first thing to prepare the preassembly process operation manual, in order to improve the efficiency of assembly, complex wiring harness to set the preassembly station, the preassembly process is reasonable or not directly affects the efficiency of the total assembly also reflects the technical level of a technician. If the preassembled part is too small or the assembled wire path is inappropriate, the workload of the total assembly personnel will be increased and the speed of the assembly line will be slowed down. Therefore, the process personnel should often stay on the site and constantly summarize.
The final step is the final assembly process. Be able to design the specifications and dimensions of tooling equipment and material box according to the assembly table designed by product development department and paste the numbers of all assembly jackets and accessories on the material box to improve assembly efficiency. Compile the assembly content and requirements of each station, balance the whole assembly station to prevent a little too much work and slow down the speed of the whole assembly line. In order to achieve station balance, the technician must be familiar with each operation and calculate the working time on site, and adjust the assembly process at any time.
In addition, the automobile wiring harness process also includes the preparation of material consumption quota schedule, working hour calculation, worker training, etc., due to the low technical content value, these will not be detailed. In a word, the electronic technology content and quality of automotive wiring harness in the car has gradually become an important index to evaluate the vehicle performance.
