Description

Technical Field

[0001] This utility model relates to the field of automotive parts appearance inspection technology, specifically to an appearance inspection device for metal terminals of vehicle connectors. Background Technology

[0002] Automotive connectors are a component that electronic engineers frequently encounter. Their function is quite simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. With the increasing level of automotive electronics, the use of automotive connectors has increased significantly. As the core component of connectors, the appearance quality of the metal terminals directly affects the reliability and safety of the connector.

[0003] Traditional appearance inspection mainly relies on manual visual inspection or simple optical inspection equipment. This has the disadvantages of a single inspection angle, difficulty in fully covering all surface defects of metal terminals, and the need for manual sorting of defective products after inspection, which affects production efficiency. To address this, we propose an appearance inspection device for metal terminals of automotive connectors. Utility Model Content
