Problems and solutions encountered in wire harness handling

When working in a wiring harness factory, partners often encounter some processing problems. Wiring harness factory from the function to be divided, there are two kinds of power lines that carry the power to drive the executive element (actuator) and the signal line that transmits the sensor input instructions. As people's requirements for comfort, economy and safety continue to improve, the types of electronic products in the car are also increasing, the automotive wiring harness is becoming more and more complex, and the failure rate of its wiring harness has increased accordingly. Wiring harness refers to the copper punching and into the contact parts of the terminal (connector) and wire and cable crimping, and then outside the plastic pressure insulator or additional metal shells, etc., to wire harness bundle formed to connect the circuit components. The processing of molded wires is more complex and problematic than that of electronic wires. Therefore, we will focus on the whole process of forming wire problems, and put forward solutions one by one.1. Cutting line: core wire shrinkage is mainly due to the wire manufacturer's drawing process is not perfect, resulting in the core wire and the outer cover of the adhesion of abnormal. Temporary countermeasures are better than scissors. The root cause is to find suppliers to solve the problem of adhesion. 2. stripping the core: the problem of copper wire breakage is mainly due to the enterprise we have two main reasons. One is the incoming wire is eccentric, so for supplier management must be carried out to solve it. There is also a choice of blades, including V- or U-shaped blade structure and the outer diameter of the blade.3. Soldering: There are many kinds of abnormal soldering, soldering and false soldering are all soldering process problems, because it will lead to poor electrical performance and more harmful! The most important thing is to train the staff regularly.4. Molding:Molding is the debugging of the equipment, which mainly depends on the technical level of the technician. Training technicians need to be trained. Complex forming lines are mainly a matter of mold design and development techniques.5. Establishment: Misalignment has not progressed in research. Work instructions, preventive fixtures and regularly conducted training management can reduce such errors in the enterprise by. Currently the main focus is on comprehensive systematic testing of wire testers.
