Bimetallic strip temperature sorting machine

Abstract

The bimetallic strip temperature sorting machine comprises a workbench, a material channel which is circularly arranged is arranged on the workbench, a plurality of heat conduction sorting inclined blocks which are arranged side by side are arranged in the material channel, and a material pushing device used for driving the heat conduction sorting inclined blocks to circularly move in the direction of the material channel is arranged on the outer side of the material channel; a discharging inclined surface is arranged at the top of the heat-conducting sorting inclined block towards the outer side of the material channel; the material channel comprises a rotary material channel and a sorting material channel, the height of the side wall of the outward side of the sorting material channel is not larger than the height of the lower end of the discharging inclined face, and a material channel heating device is arranged at the bottom of the sorting material channel. According to the bimetallic strip temperature sorting machine, qualified products and unqualified products can be effectively and accurately distinguished, bimetallic strips are sorted to be assembled into products, the qualified rate of finished temperature protectors can be effectively increased, the bad phenomena such as flashing of the assembled products with asymmetric temperature are avoided, the rejection rate of the temperature protectors is reduced, resource waste is reduced, and the production cost is reduced. The production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of processing and detection of temperature protectors, in particular to a bimetal single-chip temperature selector. Background technique [0002] The bimetal sheet in the temperature protector is a combination of two different alloys. It will generate heat when the current passes through it. Due to the different thermal expansion coefficients of the two different alloys, the alloy is bound to bend in one direction, and then the contact will be cut off when the contact is separated. The bending speed is proportional to the magnitude of the passing current, which can effectively protect the safety of electrical equipment. Since the temperature protector uses the jump performance at different temperatures to complete the switching action, it is necessary to detect and sort the temperature reversal performance of the temperature protector during production. Usually, it is necessary to limit the upper and lower ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, due to the limited detection efficiency of workers, temperature detection is not carried out after mass production of bimetal sheets or only by random inspection, and then temperature sorting is carried out when they are assembled into finished or semi-finished products of temperature protectors. The resulting products often have adverse phenomena such as flickering of the assembled product due to the temperature asymmetry of the bimetallic sheet, and then a large number of unqualified temperature protectors appear, and the unqualified temperature protectors can only be scrapped as a whole, resulting in a large amount of resources. costs, increased production costs
