线束加工一般作业流程包括裁线、剥皮、剥头、压端子、浸锡、插壳、焊接、套管、测试、外观检验、包装入库等过程。可以说每道流程都重要,需要注意的事项也比较多,直接关系到整套线束的质量。
  比如裁线要求线长度在公差范围内,太长太短都是不能流转到下个流程;
  剥皮也有长度要求,不能伤及内部芯线;
  剥头有长度要求,这直接与端子规格有关,太短太长端子压接就不合格;
  压端子重要的是拉力一定要达标,端子外观要ok;
  浸锡有上满锡和部分上锡,不能有扫把头、开叉、大头等现象,否则不合格;
  插壳容易插错插不到位,也很重要;焊接不能出现假焊、虚焊、漏焊、错焊;
  套管包括套热缩管、pvc管、缠绕管、黄腊管等,尺寸及工艺都有严格要求;
  测试包括导通测试、电阻电压测试等,不符合要求则为不良品;外观检验是在前面过程检验的补充,对整体线束外观检验,不合格的需要退回返修;
  包装入库要针对每种线束进行合理包装储存,否则合格品就会变成不良品,也挺重要的哦。


The general operation flow of wire harness processing includes wire cutting, peeling, head peeling, terminal pressing, tin dipping, shell insertion, welding, casing, testing, appearance inspection, packaging, warehousing and other processes. It can be said that each process is important, and there are many matters needing attention, which are directly related to the quality of the whole harness.
For example, line cutting requires the line length to be within the tolerance range. If it is too long or too short, it cannot be transferred to the next process.
Peeling also has a length requirement and cannot damage the inner core wire.
There is a length requirement for the stripping head, which is directly related to the terminal specification. If the terminal is too short and too long, the crimping is unqualified.
The important thing to press the terminal is that the pulling force must reach the standard and the terminal appearance must be OK.
Dip tin with full tin and partial tin, can't have broom head, fork, big head, etc., otherwise unqualified;
It is also very important that the casing is easy to be inserted incorrectly and not in place. False welding, virtual welding, missing welding and wrong welding cannot occur in welding.
Casing includes heat shrink tube, pvc tube, winding tube, yellow cured tube, etc. The size and technology have strict requirements.
Testing includes conducting test, resistance voltage test, etc. If it does not meet the requirements, it is a defective product. Appearance inspection is a supplement to the previous process inspection. For the overall wiring harness appearance inspection, unqualified ones need to be returned for repair.
Packing and warehousing should be properly packed and stored for each wire harness, otherwise qualified products will become defective products, which is also very important.
