A shrapnel welding machine

Abstract

The invention provides a shrapnel welding machine, which relates to the technical field of welding processing. The shrapnel welding machine includes a bottom support plate, the top of the bottom support plate is provided with a side support rib plate upright and fixed on the top of the bottom support plate, and the side The top of the support rib is provided with a horizontally fixed top support rib, and the top of the top support rib is provided with a through slide hole, and a slider is installed in the slide hole of the top support rib by sliding fit; The invention drives the impeller and the welding wire winding frame intermittently to rotate synchronously through the motor, etc., and cooperates with the intermittent movement of the slider to make the welding pen stop intermittently above each shrapnel, and through the impeller and the welding wire winding frame The brief rotation makes the welding stay above each shrapnel, put the molten liquid of the welding wire on the soldering piece of the circuit board, and fix the welding piece on the circuit board to improve the welding efficiency of the shrapnel.

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...

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.
