AI Technical Summary
Existing cylindrical battery welding technology cannot detect whether the probe is over-voltage when the servo module fails, leading to problems such as probe breakage, equipment collision, and cell damage.
Design a cylindrical battery welding overpressure detection mechanism that includes components such as a fixed guide rod micro-motion mechanism, a pressure detection mechanism, a control frame, a support plate, and a control mechanism. The fixed guide rod micro-motion mechanism is moved by a motor, and real-time detection and alarm are achieved by combining a pressure sensor and a micro switch to prevent damage under overpressure conditions.
It enables real-time overvoltage detection in the event of servo module failure, preventing damage to probes and battery cells, improving equipment stability and welding qualification rate, timely detection and replacement of vulnerable parts, and ensuring the safety of equipment and battery cells.
