Description

Technical Field

[0001] The utility model relates to welding equipment, in particular to silver spot welding equipment for static contacts of small circuit breakers. Background Art

[0002] A miniature circuit breaker is an electrical device used for overload and short-circuit protection. They are usually installed in distribution boxes in homes, offices or industrial facilities to protect circuits from overcurrent damage. When it detects that the current exceeds a predetermined value, the MCB will automatically disconnect and cut off the power supply, thereby preventing accidents such as fire.

[0003] In small circuit breakers, due to the large number of parts, different shapes and complex welding processes, these limitations directly lead to the need for a large number of people to perform manual welding during the welding process. In particular, the welding of static contacts and silver spots is basically done manually, which directly affects the welding quality and production efficiency according to the workers' own proficiency. There are also welding equipment for welding static contacts and silver spots, but workers are required to clamp and fix the static contacts and silver spots first, and then add solder paste before starting the operation. The degree of automation is low and manual participation is still required. Utility Model Content
