What are the common challenges in the wire harness manufacturing process?
Author：
Wire harness manufacturing industry is based on the cable/connector/plastic parts and tape these raw materials together, the key technology is stripping and cutting the wire to play the terminal and then additional welding crimping heat shrinkage foam and visual inspection of this series of processes; automotive wiring harness designers will be based on the vehicle electrical distribution with CAN (Controller Area Network - BUS) bus technology to complete the alignment and Production drawings, including formal floor plans and 3D assembly drawings, and then to the harness manufacturer, the harness manufacturer and then according to the customer's drawings for the production and confirmation of the assembly board drawings, and then the factory can start production and manufacturing.
At this stage, there are several common problems in the manufacturing process of internal wiring harness production.
1, insert the wrong line means that the wire with the terminal is inserted into the incorrect connector hole, for example, should be inserted into the No. 1 hole, because the staff error inserted into the next hole No. 2, which will lead to no effect on the function, is a serious mistake.
Generally, the corresponding part of the tooling board will be posted on a clear diagram to inform workers what color wire should be inserted into which hole, in addition to the workers compared to the safety procedures for work will not be wrong; such incorrect errors are mainly new employees and speed up the production of the case, we must strengthen training and develop protective measures, the last step there is an electrical test bench, so generally do not worry too much.
2, connector or fuse box damage within the factory process there are many, must be set in advance to supervise the node to collect data to see where the error occurred in the step, followed by analysis and the development of measures; generally incoming materials and transport process caused by the destruction.
3, the connector push lock pull stage, this step is a must, first insert the hole in place to push, this time there will be a crisp sound, followed by a gentle pull outward, if the wire does not go back, it means that the plug in place and fixed; if this step is not done as well as the function will be invalid, pay special attention to it.
