Clamping structure for circuit board welding

Abstract

The invention discloses a clamping structure for circuit board welding. The clamping structure comprises a weld holder and a hydraulic cylinder, wherein a baffle, a supporting rod and an air cylinder are fixed to the weld holder, a movable block is hinged to the output end of the hydraulic cylinder, and the top end of the supporting rod is hinged to the bottom surface of the movable block; a chuck is fixed to the side wall of the movable block, a top plate is fixed to the output end of the air cylinder, and a rectangular groove is formed in the vertical portion of the baffle; a plurality of rollers parallel to the top plate are arranged in the rectangular groove in a rotary mode, the end of one side of the top plate is aligned with the outer wall of each roller in the vertical direction, and an elastic rubber mat is installed on the upper surface of the top plate. In the whole circuit board welding process, lifting and fastening of a circuit board are achieved by controlling the air cylinder and the hydraulic cylinder, movement of the circuit board during welding can be avoided through a U-shaped clamping area formed by the chuck, the top plate and the baffle, and then the welding precision of components on the circuit board is improved.

Description

technical field [0001] The invention relates to the field of welding of electronic components, in particular to a circuit board welding and clamping structure. Background technique [0002] In the prior art, the circuit board needs to be welded accurately and firmly when welding the electrical components, so it needs to be carried out in an environment with a uniform light source. At the same time, since the circuit board needs to weld multiple electrical components, that is The circuit board needs to be fixed before welding. The usual method is to use the pressure plate and bolts to fix the circuit board, and then perform welding. Further, in order to improve the stability of the welding, the circuit board is usually fixed at multiple points, increasing the The process of the circuit board before and after welding greatly reduces the welding efficiency of the circuit board, and at the same time increases the work intensity of the operator.
