Description

[0002] The moving spring sheet is a kind of flat and elastic metal sheet, generally made of copper, used as the main component of the electrical switch in the relay, and the connection with the wire is the key link to ensure the normal operation of the relay. The connection between the moving spring sheet and the wire is mainly realized by welding technology, so the welding process has a direct impact on the performance and reliability of the relay. The quality of welding not only determines the stability of the connection, but also affects the electrical conduction efficiency and contact resistance between the wire and the moving spring sheet. Therefore, ensuring the high quality and stability of the welding process is crucial for the long-term reliable operation of the relay.

[0003] Currently, relay manufacturers use automatic welding and automatic stripping devices to weld copper sheets and wires. To ensure the accuracy of the welding position, the automatic welding device is usually equipped with a jig for placing the copper sheet. However, the way of feeding and discharging using the jig is cumbersome, which reduces the overall welding efficiency. In addition, after the wire is batch segmented and stripped by the automatic stripping machine, manual operation is required to move the wire segment to the automatic welding device, or an additional mechanical hand is used for transportation.
