Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness manufacturing equipment technology, and in particular to a multi-model automotive wiring harness assembly and testing platform. Background Technology

[0002] As a core component of automotive circuitry, automotive wiring harnesses play a crucial role in power transmission and signal delivery. Their assembly precision and electrical performance directly impact the safe operation and reliability of automobiles. Automotive wiring harness assembly and testing platforms are integrated devices that combine wiring harness assembly, online testing, and data traceability, and are widely used in the production lines of automotive OEMs and component suppliers.

[0003] Existing automotive wiring harness assembly and testing platforms, when in use, employ traditional manual clamping or pneumatic single-drive clamping for the multi-group wires of the wiring harness, making the positioning process cumbersome. This results in uneven force on the wires, which can easily lead to loose clamping and displacement, affecting the consistency of their spacing. Furthermore, the traditional method of manually sorting the wires in wiring harness production is cumbersome, causing problems such as cross-entanglement and positional misalignment of the multi-group wires during assembly and testing. Summary of the Invention
