Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to a mechanism for automatically breaking off excess residual material after welding of a spring piece used for a mute key spring piece of a mobile phone. Background Art

[0002] In the existing automated processing of mobile phone mute button shrapnel, the mobile phone mute button shrapnel needs to be welded. After welding by welding equipment, it is also necessary to carry out excess residual material processing detection and tray loading process. The excess residual material is generally broken by a folding mechanism, and the direction of the product needs to be changed after breaking.

[0003] However, currently, the excess residues after welding of the mobile phone mute button shrapnel are often broken manually or by a mechanism to break a single group of products at a time, and then the direction of the product is changed manually. The manual or single-time breaking mechanism is inefficient and the breaking defect rate is high. Therefore, a mechanism that can break the excess residues at the same time and can rotate multiple groups of products at the same time is urgently needed to solve the above problems.

[0004] In the patent document with application number CN201220251139.X, a welding structure of a grounding spring is disclosed, which includes a material strip, a pre-cut part and a grounding spring with one end welded to a hardware insert, and the three are formed in one piece. The material strip is fixedly connected to the grounding spring, and a pre-cut part is arranged between the material strip and the grounding spring; one end of the pre-cut part is connected to the grounding spring, and the other end is connected to the material strip, and the material strip is used to fold the material after the grounding spring is welded, and a positioning hole is opened on the material strip.

[0005] However, when the welding structure of the grounding spring piece in the above utility model is used to fold the excess residual material after welding the grounding spring piece, it needs to be broken manually, and then the direction of the product needs to be changed manually, which is inefficient and has a high failure rate.
