Rectangular Enameled Wire Analysis Of The Problem

  •  

    When the electronics industry often sees returns, the quality reason is "multi-threaded." This is indeed wrong for the enameled wire factory.
    Since the current machines for producing enameled wire are single-end pay-off and single-end take-up, there is no multi-line.
    In practice, most "multithreading" occurs in consumer electronics factories. During the blanking process, the transformer skeleton must be shut down every few minutes to replace the transformer. When the machine is stopped, the pay-off tension of some machines is not in place (rectangular enameled wire). Due to inertia, the upper coil collapses and squeezes the lower wire. When it is turned on again, the wire is crushed, causing the wire to break. Formed the beginning of the chaotic line. CCA wire
    After the wire is broken, it cannot be used normally, and the spool must be removed from the winding machine. Of course, the ones that are disposed of can continue to be used. However, in the process of dealing with the chaotic wire, if one wire is accidentally broken, three heads will appear, and two wires will be broken, which will result in five heads... As promised, this shaft cannot be processed (enameled wire), from the manufacturing process to the warehouse , The warehouse returns to the production plant in the name of multi-line. This is how "multithreading" occurs and returns.
    In fact, long thread ends are easy to handle: use a sharp blade to pick and break a few turns of thread ends, grab the broken thread ends and pull them up. Until a head appears.
    Note: ①The method of reversing the line is the same.
    ②The customer's interruption and confusion during the line setting process may also be related to the product line not being tight --- when the product line is loose.
    ③Some production plants, such as Dongguan Yimou, add winding enameled wire segments to the optical axis to reduce costs. It can also be regarded as an extraordinary multithreading. In 1974, the national standard agreed to increase the line segment (enameled copper round wire), but it must be marked. In most enameled wire factories, only one wire segment is needed for a shaft.
    ④ In the production process of enameled wire, two or more wires in the oven are connected together, which is actually a kind of waste wire. If the operator forgets to remove the waste thread from the machine, it can be regarded as an extraordinary multi-thread head. However, this probability is about one in a million.
    ⑤The main reason for the multi-strand wire (enameled wire) of the same weight is that the wire is not tightened when leaving the factory, and the wire collapses during transportation.
