Steps of harness processing

Acceptance link: It is mainly an acceptance of incoming materials. ROHS instruments or other instruments can be used for basic tests. The main hazardous substances for acceptance are lead, mercury, cadmium, brominated biphenyl polybrominated diphenyl ether, etc.
Place the qualified wires on the intermediate transfer wire rack for wire feeding. At this time, you should pay attention to avoid scratching the wire surface.
Thread cutting; At this time, the wire cutting machine shall be used to cut the wire into the required length.
Pay attention to the following safety points during the operation of the winding machine: A. Stop the machine immediately after the wire is knotted, and continue the winding after the wire is straightened out, otherwise the wire and the wire feeding wheel will be damaged. B. Attention must be paid to cooling the off-line machine, otherwise data failure will occur.
Peeling: according to the sop requirements, the insulating skin is mainly made of pneumatic peeling machine
Pneumatic stripping machine is a wire stripping machine that works by using compressed air. It can strip wires in the middle so that other wires can be connected to the wire stripping position. The equipment uses pneumatic foot switch to control the start and stop of wire stripping, and can strip up to three wires at the same time.
Pay attention to the following safety points during the operation of the air stripper: A. When multiple wires are stripped at the same time, the wire body must be parallel and not overlapping, otherwise the wire body will be stripped. B. Be careful not to let your fingers enter the travel range of the stripping blade and the crimping jaw, otherwise your hands will be injured.
Twisting: arrange and twist the conductor at the joint. The twisting machine is mainly used.
Riveting: Rivet the conductor and plug terminal at the joint with the terminal machine.
Key points: Before crimping, carefully check the wire type, specification, color, terminal specification and crimping end stripping size on the card. The first product must be subject to self inspection of appearance and tension and special inspection by inspectors, and mass production can be started only after it is qualified.
Assembly: Assemble the processed harness, mainly the plastic plug shell.
Test, the final test shall be carried out for the product, and the product can be packaged only after it is qualified.
A. When the electrical inspection is qualified, the computer will display qualified and give a long beep prompt
B. On the appearance of the harness, there is no tape head rolling or tape shrinking and rolling, nor is there any wire exposed or open
