Circuit board soldering auxiliary positioning device and method

Abstract

The application belongs to the technical field of circuit board welding positioning, and discloses a circuit board welding auxiliary positioning device and method, which comprises a base, a circuit board laser welding machine arranged above the base and used for welding, and a circuit board body to be positioned, further comprises: an auxiliary positioning assembly, which is provided with four groups and is located above the base; a contact piece, which is symmetrically distributed on both sides of the base; wherein the auxiliary positioning assembly comprises a positioning seat, and a push block is movably connected in the positioning seat. The application uniformly adsorbs the bottom surface of the circuit board body through the adsorption mechanism; the whole replaces the traditional single-side rigid extrusion structure, can effectively avoid the slippage, warping and stress deformation of the circuit board body during the welding process, eliminate the defects such as welding point deviation, virtual welding and continuous tin, greatly improve the laser welding precision and product consistency, and improve the stable positioning property.
