Problems solved by technology

During the brazing process of the electromagnetic relay, problems such as uneven weld seam, unstable brazing rate, large deformation of the weldment, poor dimensional consistency, and solder spatter are prone to occur. Insufficient control of the operation process, etc., will eventually lead to a decline in the quality of the sealing of the relay and a large number of scrapped finished products

Abstract

The invention discloses an electromagnetic relay contact part laser brazing method and system and a clamp. The method comprises the following steps: firstly, fixing the positions of a leading-out end and a reed of an electromagnetic relay, then putting a welding flux into the connecting position of the leading-out end and the reed, and finally melting the welding flux by using laser to complete brazing. The welding part of the electromagnetic relay is welded by adopting the laser brazing method, so that the possibility that the reed is scalded in the welding process is avoided; the welding flux is uniformly heated and does not generate welding spatter; and no welding spatter is generated in laser brazing welding, and particle inspection is not needed.

Description

Technical field [0001] The present invention belongs to the field of electromagnetic relay, in particular, involving an electromagnetic relay contact portion laser brazing method, a brazing system, and a clamp. Background technique [0002] In the electromagnetic relay manufacturing process, the contact portion of the contact portion is connected to the carbon pen contact welding of the connection of the motor spring sheet, and the brazing technology is a mature process in the relay industry, with a complete set of process test verification. method. Conventional relay brazing control requirements include welding parameters such as electrode pressure, welding time and welding current. During the brazing of the electromagnetic relay, it is prone to no uniform weld, the brazing rate is unstable, the welding is large, the size of the size and the solder splash is the cause of the tooling fixture design is unreasonable, and the strength of the brazing equipment is insufficient. The op...
