Wire Harness Manufacturing Process(2)

This article is a brief introduction to the process of wire harness manufacturing. Please read on for more information.

IV. Assembling

It is the crimped and sub-assembled semi-finished line in accordance with the location and lines specified in the case board, a row of boards, wiring, winding, wrapping, and finally get the finished product process. Assembled case board is best printed on photo paper.

In the process of operation, the staff should strictly follow the regulations of the board to subassembly and assemble, and should promptly raise problems to the technical staff. If you accidentally insert the wrong terminal or encounter special circumstances during the operation, you should notify the person in charge as soon as possible to solve.

When inserting the terminals should be in accordance with the following requirements: one insert, two listen, three pull back.

Some terminals in the insertion of the positive and negative, so when encountering difficulties in the insertion of the terminal should be adjusted in time to the direction of insertion of the terminal, do not press hard into.

After the normal insertion will hear a slight "pop" sound. After hearing the sound, do not force, but should be pulled back to see if there is no trace of loosening.

If the terminal no matter which direction to turn can not be inserted, it is possible that the terminal is wrongly pressed, or the plugger distribution error, at this time should notify the technical staff as soon as possible for a detailed check to determine its rectification program.

V. General assembly

The general assembly is a process immediately following the assembly, including the large bellows on the trunk, the trunk and some small bellows winding, etc. The most important thing in this step is to coordinate the division of labor with the assembly, because it is hard to make a clear boundary about who should operate the bellows, and the bellows on the main stem or the bellows with diameter over Φ13 can be considered to be finished by the general assembly.

VI. External inspection

The external inspection is to check whether the size and appearance of the product are qualified. The requirements of external inspection are as follows.

First, the size can only have positive deviation, can not appear negative deviation, that is, only long can not be short, short will appear when the installation can not pull the situation, and most often can not exceed 10mm.

Second, the exposed corrugated tube or silicone tube outside the wire harness can not exceed 5 mm.

Third, there can not be an excessive "storm line" (the bellows can not wrap the line body).

Fourth, the terminal has no obvious inappropriate situation.

In practice, in fact, it is not necessary to measure each piece of product with a tape measure. We only need to measure out an accurate, and then to this as a reference sample, after each one to bring and this one next to the control, if there is no obvious difference in length, also qualified.

VII. Electrical inspection

An electrical inspection is in the help of some electronic testing equipment to test whether the circuit is smooth.

Electrical inspection equipment may vary from one manufacturer to another. Now the inspection equipment almost all joins the assistance of the computer so that not only makes the programming convenient but also to speed up the efficiency of the inspection.
