Automatic silver point welding equipment for bimetal sheet of thermal protector

Abstract

The invention discloses automatic silver point welding equipment for a bimetal sheet of a thermal protector. The automatic silver point welding equipment comprises a bimetal sheet feeding mechanism, asilver belt feeding mechanism, a material cutting mechanism, a material pushing mechanism and a welding mechanism. The bimetal sheet feeding mechanism, the silver belt feeding mechanism, the materialcutting mechanism, the material pushing mechanism and the welding mechanism are respectively fixed on a worktable. The silver belt feeding mechanism includes a conveyor belt, a driving wheel, a driven wheel and a first motor for driving the driving wheel to rotate. The material cutting mechanism includes an upper blade and a lower blade disposed opposite to the upper blade and arranged in dislocation with upper blade. The material pushing mechanism includes a push rod and a cylinder for driving the push rod to move. The welding mechanism includes a positive electrode welding pin and a negative electrode welding pin which are arranged oppositely. According to the equipment, the silver belt feeding mechanism can smoothly convey silver belts to the material cutting mechanism for cutting intosquare silver points to be welded on bimetal sheets, the overall operation speed of the equipment is stable, the phenomenon of material blocking is reduced, the failure rate of equipment operation isreduced, and production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, in particular to an equipment for automatically welding silver dots on a bimetal sheet. Background technique [0002] The thermal protector is a combination of two different alloys, which will generate heat after passing through the current. Because the thermal expansion coefficients of the two different alloys are different, the alloy is bound to bend in one direction, and the contact will be separated, and the power will be cut off. The bending speed is directly proportional to the magnitude of the current passing through it. This protects the electrical equipment. [0003] Among them, the bimetal is an important component of the thermal protector. The existing process of welding silver dots on the bimetal is as follows: put the silver dots with welding into the vibrating plate, and send the silver dots into the bimetal through the vibrating plate. On the running track of the strip ...

Problems solved by technology

[0005] However, when the silver dot falls on the bimetal sheet through the silver dot drop channel, there will still be a material jam problem, resulting in a high failure rate of the equipment and low production efficiency.
