Summary of wire harness quality inspection

In order to ensure the wiring harness quality of the harness processing plant, there are several links in the harness quality inspection:

1, cutting line: check the size of the wire is not in line with the relevant requirements, the model is not correct. The incision must be neat, can not scratch the wire, and the wire can not have dirty situation.

2, group processing: check the pruning is not neat, the size of the right, in the pruning group can not be assigned to the core line.

3, stripping the skin: check the stripping mouth is not neat, stripping the size of the wrong, can not be stripped of marshalling wire and core.

4, stripping the skin: check the stripping mouth is not neat, stripping the size of the right, there is no core stripping, there is no stripping copper wire; in the semi-stripped when the insulator must not fall off.

5, sets of shrink tube: carefully check the shrink tube model and size is not correct.

6, ready to solder: check the temperature of the tin furnace on the right; in the preparation of solder before the core and copper wire to be sorted out, check there is no bending, bifurcation and discount situation.

7, solder: check the temperature of the soldering iron is not correct; can not burn the insulation, tin point to be smooth, no tin tip, not Weld and false welding.

8, the terminal crimping: check the terminal and wire specifications is not correct; terminal crimping there is no tilt, there is no Lama mouth situation.

9, the terminal is inserted: check the terminal and connector model is not correct; the terminal has no deformation and damage, etc.; check the terminal is not wrong plug, plug or insert is not in place.

10, assembly shell: check the shell is not scratched, loaded wrong or burr, etc., there is no missing parts, screws are not oxidized, loose, twist and discoloration and so on. If the shell is directional, then it must be assembled according to the requirements.
