Description

Technical Field

[0001] This invention relates to the field of wire harness packaging technology, and in particular to a wire harness winding and binding device. Background Technology

[0002] In the production and packaging of wire harnesses, winding and binding are key processes. Currently, existing technologies mostly employ manual winding or semi-automated equipment, which has the following shortcomings:

[0003] Manual winding is labor-intensive, inefficient, and difficult to meet the needs of large-scale production.

[0004] The lack of effective control over the tension of the wire harness during the winding process leads to inconsistent winding tightness and poor wire harness forming consistency, which affects product quality.

[0005] After the wire harness is wrapped, it needs to be tied manually, which is cumbersome and the tying force is uneven, which can easily lead to loosening or being too tight, resulting in poor stability.

[0006] During the winding process, the connectors and wire tails at the ends of the wire harness lack effective fixation, which can easily lead to displacement, resulting in messy winding and affecting subsequent use;

[0007] The existing equipment is multifunctional but lacks coordination in processes such as winding, transferring, and binding, requiring manual assistance for transportation, which further reduces production efficiency.

[0008] Therefore, designing an integrated device that can automatically wind, uniformly arrange, automatically bind, and stably fix the ends of the wire harness is the key to solving the above problems. Summary of the Invention
