PCB board height limiting mechanism for character jet printer

Abstract

The utility model relates to the technical field of PCB manufacturing, concretely is a character printing machine with PCB height limiting mechanism, the utility model discloses: printing machine body, moving mechanism, printing head, control box, height adjusting mechanism and width adjusting mechanism, printing machine body inside one side fixed mounting has moving mechanism, the mobile end below of moving mechanism fixedly assembled with printing head, printing machine body upper end away from the side fixed mounting of moving mechanism with control box, printing machine body inboard center place assembly has height adjusting mechanism. The utility model drives the double -end screw rod rotation through drive motor, makes both end nut seat reverse synchronous movement along the guide groove, passes through the connecting rod again and converts into the vertical lifting of anchor support seat, realizes the accurate adjustment of PCB board and printing head vertical distance, avoids the error of traditional manual regulation, can control height deviation in the extremely small range.
