First of all, the acceptance of incoming materials, this can be through the relevant instruments to carry out environmental protection tests, after the test to see if it is in line with the ROHS standards, in the incoming materials can not contain lead and mercury and other harmful substances. Then the wire feeding equipment, mainly the need to process the wire harness on the top of the transit feeder, be careful not to scratch the surface of the wire. Next is to feed the wire, put the wire on the feeder for fixing. After that is to cut the wire, is the use of wire cutting machine to cut the wire to the appropriate length, in doing this work, pay special attention to, can not cut the surface of the wire, can not be cut off the copper wire, stripping the length of the error is best not more than 1 mm. Further is the stripping of the wire, according to the standard requirements of the joints of the wire corresponding to the length of the insulation of the outer skin stripped. The same error should not exceed 1 millimeter. In addition is the twisted wire, in the joints of the place for the organization and twisted wire, can not scratch the surface of the wire, be sure to twist the copper wire to tighten, do not use the situation of loose wire. The last is to connect the terminals, the joints of the conductor and plug terminals for connection, pay attention to the width and height requirements.
When these processes are completed, the wiring harness processing is basically complete, only the final assembly process. For example, there is the assembly of the product, assembly of plastic plug shell, must meet the product requirements of the torque. Then there is the test of conduction, the use of instruments for the harness conduction test, do not appear disconnection, poor contact and insulation and other phenomena. Finally, the packaging light sealing, the use of tape to the finished wire harness into a cardboard box, the seal should be flat, packing tape when the tight package carton, can not appear off the case.
