Description

technical field [0001] The invention relates to the technical field of circuit breaker production, in particular to an automatic assembly device for contacts and copper sheets of a circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. A circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a trip unit, and a housing. Contacts are electrical contact materials used for switches, relays, electrical connections and electrical plug-in components, also known as electrical contact materials, generally divided into two types: contact materials for strong electricity and contact materials for weak electricity. The contact material should have a suitable hardness. A smaller hardness can increase the contact area under a certain...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of low assembly efficiency and poor assembly quality of the contacts and copper sheets used in the existing circuit breakers, and provide a contact deburring device to facilitate better control of the contact clamping force and improve the deburring device. The quality of burrs; through the contact synchronous belt conveying device, it cooperates with the contact cleaning coating device and the copper sheet assembly device. While conveying, it is convenient to coat the contact and assemble it with the copper sheet, which improves the conveying efficiency and saves equipment. Space; through the contact cleaning and coating device, it is convenient to fix and position the copper sheet, and improve the welding quality of the copper sheet assembly; through the copper sheet assembly device, it is convenient to cut the copper sheet stably, and improve the cutting quality of a circuit breaker contact and Copper sheet automatic assembly equipment
