After the battery cells are manufactured, battery cells with the same or similar performance can be connected in series through a string welding machine. During this process, glue dispensing operations will be performed at the main grid electrode and the fine grid electrode. The glue height needs to be tested to ensure that the glue completely covers the main grid to fix it.

· Pin Defects: Bent, deformed, or missing inverter pins can disrupt electrical connections, leading to performance degradation or system failure.

· Precision Requirements: Traditional detection methods often struggle to identify minor deformations or deviations in pin height and alignment.

· Mass Production Challenges: High-speed production lines require detection systems that are both fast and precise, maintaining quality without slowing operations.
