What Are The Processes Of Processing And Production Of Wiring Harness?

What are the processes of processing and production of wiring harness? The quality of wiring harnesses is an important consideration for equipment manufacturers when looking for suppliers. Choosing an excellent wiring harness processing company not only needs to consider the price, but also needs to see the process of wiring harness processing.
Because the process is detailed, it is directly related to the mass of the harness. Electronic wiring harness manufacturers called excellent wiring harness processing enterprises. Wiring harness processing should be comprehensive and meticulous, strict management, to ensure good quality.

1. Receiving materials: Environmental testing with ROHS instrument is carried out to test whether the feed required by all wiring harnesses meets ROHS standards.
Equipment required: OHS tester equipment.
Process requirements: The feed does not contain lead Pb, mercury Hg, cadmium Cd, bromo-biphenyl PBB polybromo-diphenyl ethers and other hazardous substances.

2. wire feeding equipment: the required processing line on the transmission line rack.
Equipment required: Wire delivery rack.
Process requirements: Be careful not to scratch the wire surface.

3. wire feeding: wire into the wire feeding machine for fixing.
Equipment required: Wire delivery rack.
Process requirements: Be careful not to scratch the wire surface.

4. Cutting line: Use the cutting machine to cut the required length of wire.
Equipment required: computer wire cutter.
Process requirements: do not cut wire surface; Don't cut the copper wire; The length of peeling error shall not exceed ±1mm.

5. Wire stripping: according to SOP requirements, strip the corresponding length of wire insulation layer at the joint.
Equipment required: pneumatic peeling machine.
Process requirements: The surface is not allowed to be crushed; The length of the peel shall not exceed ±1mm.

6. Twist the strand: complete and twist the conductor at the junction.
Equipment required: Twisting machine.
Process requirements: No scratches are allowed to scratch the surface of the wire; The copper wire must be tightened and loose wires are not allowed.

7. riveting terminal: the conductor and plug terminal riveted on the joint.
Required equipment: Terminal machine.
Process requirements: terminal deformation is not allowed; It must meet the requirements of tension, riveting height and width.

8. electronic wiring harness manufacturers said product assembly: plastic plug shell assembly.
Required equipment: Electric screwdriver.
Process requirements: screws are not allowed to show the surface of the rubber shell; The torque required for the product must be achieved.

9. Continuity test: The instrument is used for wire harness test.
Equipment required: conduction tester.
Process requirements: do not allow short circuit, open circuit, wiring error, poor contact, poor insulation, etc.

10. Packaging and sealing: Wrap the finished wiring harness in plastic bags and put it in a carton.
Equipment required: harness sealer and baler.
Process requirements: seal should be smooth; The packing tape shall be tightly wrapped in the carton and shall not fall off.
