Elastic piece welding machine

Abstract

The invention provides an elastic piece welding machine and relates to the technical field of welding processing. The elastic piece welding machine comprises a bottom supporting plate, wherein a sidesupporting rib plate vertically fixed to the top end of the bottom supporting plate is arranged at the top end of the bottom supporting plate, a horizontally fixed top supporting rib plate is arrangedat the top end of the side supporting rib plate, a penetrated slide hole formed in the top end of the top supporting rib plate, and a slide block is mounted in a slide fit manner in the slide hole ofthe top supporting rib plate. An electric motor drives an impeller and a bonding wire reel to rotate synchronously and intermittently at equal intervals. Matched with intermittent movement of the slide block, a welding pen stays intermittently above each elastic piece. As the impeller and the bonding wire reel rotate intermittently, a liquid smelted by a bonding wire is put onto a welding piece of a circuit board in the process that the welding gun stays above each elastic piece so as to weld and fix the welding piece to the circuit board, so that the elastic piece welding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of welding processing, in particular to a shrapnel welding machine. Background technique [0002] Shrapnel is an instrument used in buffer shockproof devices and relay delay devices of machinery and vehicles. It is used in operating mechanisms in different environments according to the characteristics of materials. Spring sheets are widely used in various contact devices, and the most used ones are Straight cantilever leaf spring with the simplest shape. The resistance of the contact piece must be small, so it is made of bronze. The characteristic of the shrapnel is that it is easy to bend in only one direction - the minimum stiffness plane, and has a large tensile stiffness and bending stiffness in the other direction. Therefore, leaf springs are very suitable for sensitive components, elastic supports, positioning devices, and flexible connections in detection instruments or automatic devices. [0003] A...

AI Technical Summary

Problems solved by technology

[0006] In view of the problems in the prior art, the purpose of the present invention is to provide a shrapnel welding machine to solve the existing welding of shrapnel, mainly by manually holding a welding pen or holding a welding pen by a machine for welding. During the welding process, It is necessary to support and fix the shrapnel. Because the structure of the shrapnel is curved, it is prone to uneven force when it is supported and fixed, resulting in sliding during the welding process, which affects the technical problem of the position accuracy of the shrapnel when it is soldered on the circuit board.
