Circuit board substrate feeding structure and etching apparatus

Abstract

The present application relates to the technical field of circuit board etching, and in particular to a circuit board substrate feeding structure and etching equipment, comprising: a rack; a plurality of parallel driving rollers rotatably mounted on the rack for conveying the substrate; a synchronization mechanism connected to the ends of all the driving rollers for forcibly synchronizing the rotation of each driving roller; a pressing unit arranged above the driving rollers for providing multiple-point independently adjustable vertical pressure to the passing substrate; a supporting mechanism arranged between adjacent driving rollers for supporting and guiding the edges of the substrate from the bottom; and an equalizing mechanism connected to the bearing seats of at least part of the driving rollers for driving the driving rollers to reciprocate along the axial direction. The present application has the effects of ensuring smooth substrate conveying, preventing substrate damage and high-precision conveying.
