Description

Technical Field

[0001] The utility model relates to the field of parallel wire harness production, in particular to fixed-length parallel wire harness end branching production equipment. Background Art

[0002] The parallel wiring harness is a common wiring harness product in electronic circuit connection. It consists of several single wiring harnesses arranged side by side. When producing the parallel wiring harness, several copper wires are usually set on the mold. After forming a flat and long parallel wiring harness component through integral injection molding, it is wound into a reel-shaped parallel wiring harness reel. Then, the length of the wiring harness is cut to a fixed length according to the production specification, and several wiring harnesses at the wiring harness ends at both ends of the parallel wiring harness are split and cut to connect each wiring harness to the wiring harness terminal.

[0003] However, the existing wire splitting equipment for the ends of parallel wire harnesses usually uses a cutting head with several side-by-side blades to split and cut the continuously moving forward wire harnesses; the blades may be offset or blunt, and at this time the blades will directly cut through the protective rubber layer and contact or even cut the copper core, resulting in defective parallel wire harnesses. After the fixed-length parallel wire harnesses are split, they are piled up in the material area and then proceed to the next production process. The diameter of each wire harness in the side-by-side wire harness is small, and it is difficult for the staff to intuitively select defective fixed-length wire harnesses with their right eyes, which can easily lead to the outflow of defective side-by-side wire harnesses, resulting in an increase in the defective rate of subsequent products, seriously affecting the stability of the quality of subsequent products. Therefore, it is necessary to improve the production equipment and production process for splitting parallel wire harnesses. Utility Model Content

[0038] The first circuit 40 is electrically connected to the cutter head 62, and the second circuit 50 is electrically connected to the harness reel 80 of the drum mounting seat 20; the first circuit 40 and the second circuit 50 are electrically connected to the control center 30; the control center 30 is provided with an alarm module and a control module;

[0039] The production process includes the following steps:

[0040] S1: Install the wire harness reel 80 on the drum mounting seat 20, and pull out the parallel wire harnesses of the wire harness reel 80 and pass them through the wire splitting assembly 60 and the cutting assembly 70 in sequence;
