Bimetallic strip feeding system for heat protector and automatic welding machine applying same

Abstract

The invention discloses a bimetallic strip feeding system for a heat protector, and relates to the technical field of manufacturing of temperature control electronic elements. In the bimetallic strip feeding system for the heat protector, a bimetallic strip loading device is provided with a poking mechanism for eliminating bimetallic strips with a nearer gap therebtween from a loading path; a bimetallic strip carrying device is provided with a pressing piece on a groove part of a carrying groove body; a carrying channel for allowing feeding of the bimetallic strips one by one is formed between the pressing piece and the carrying groove body; a bimetallic strip feeding device is provided with a position-fixed pressing plate on a groove of a feeding block; a space for singly feeding the bimetallic strips is formed between the pressing plate and the groove; finally, the bimetallic strips on a bimetallic strip feeding stop station are shifted onto a machining platform by the feeding device, so that the bimetallic strips cannot be laminated in the whole conveying process; and the bimetallic strip feeding system is stable and reliable in work, realizes automation, and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of manufacturing temperature-controlled electronic components, and more specifically, relates to a bimetal feeding system for a thermal protector and an automatic welding machine using the same. 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. Thermal protectors usually use a bimetallic strip as a temperature sensing element. When the electrical appliance is working normally, the bimetallic strip is in a free state and the contacts are in a closed / open state. When the temperatur...

Problems solved by technology

However, the thickness of the bimetallic sheet is very thin, about 80 g. During the transportation and transmission of the bimetallic sheet, two adjacent bimetallic sheets are easily laminated or the contact edges of the two metal sheets are laminated. The processing procedure has caused a great impact. If the stacking phenomenon occurs, manual processing is required. This process of manual adjustment will undoubtedly increase the workload of the operator, reduce production efficiency, and increase production costs.
