Board grinding device for circuit board processing

Abstract

The invention discloses a board grinding device for circuit board machining, and relates to the technical field of circuit board machining equipment, the board grinding device comprises a main body and a circuit board, fixing frames are fixed to the two sides in the main body, and the inner sides of the two fixing frames are elastically connected with elastic clamping frames. By integrating automatic clamping, double-sided synchronous polishing and brushing, stepping type automatic conveying and reciprocating lifting polishing structures, the problems that traditional manual board polishing is tedious in operation, low in efficiency, unstable in quality and the like are effectively solved; the device adopts an elastic clamping and centering guide mechanism, can be adaptive to automatic positioning and clamping of circuit boards with different thicknesses, and does not need to be manually held by hands, turned over and secondarily positioned after feeding, so that the operation process is greatly simplified; the double polishing brushes synchronously rotate to work and are matched with the lead screw to drive reciprocating lifting, one-time continuous polishing of the two faces of the circuit board is achieved, the machining period is remarkably shortened, and the overall production efficiency is improved.
