When factories with low manufacturing capacity can pass the first product inspection, the quality inspector will control the secondary inspection of kanban materials. This error-proofing method cannot completely eliminate the occurrence of errors. The phenomenon of using the wrong wire mainly occurs when the employees are fatigued or the work is fast-paced. Therefore, when arranging the wire cache storage racks, the wires with similar color, wire diameter, and wire type must be stored in staggered rack addresses to avoid The operator takes the wrong wire, for example: store the 0.35FLRY-B red/blue wire and 0.35FLRY-B red/purple wire; the 0.5AVSS yellow wire and the 0.5AVSS yellow/white wire, etc. The label on the material is eye-catching and can be effectively identified.
Cutting and crimping the bundled semi-finished conductors, the whole batch is labeled with the wrong kanban number, resulting in the use of wrong semi-finished materials in the subsequent process. The reason is that after the operator printed the labels of the semi-finished conductors in batches, there was no self-inspection label and reprinted label after switching the production kanban. Therefore, when compiling the wire binding protection process card, the kanban label is indicated as the inspection content, and batch printing of semi-finished labels is prohibited.
