Printing flatbed leveling method and device

Abstract

The invention discloses a method and device for leveling a printing plate, belonging to the technical field of fused deposition modeling 3D printing. The height of the four corners of the printing plate is used to obtain the inclination angle of the printing plate; based on the inclination angle of the printing plate, a leveling process is performed on the printing plate. In the present invention, the height of the four corners of the printing plate is acquired by a rangefinder, the inclination angle of the printing plate is obtained according to the heights of the four corners of the printing plate, and the printing plate is leveled based on the inclination angle of the printing plate , the inclination angle of the printing plate can be quickly obtained, so as to quickly level the printing plate, avoid manual leveling, and optimize printing quality.

Description

technical field [0001] The invention relates to the technical field of fused deposition modeling (FDM) 3D printing, in particular to a printing plate leveling method and device. Background technique [0002] Existing 3D printers usually manually adjust the fixing screws around the printing plate, so that the four corners of the printing plate and the printing nozzles maintain the same distance, but the accuracy is poor, the steps are cumbersome, and the time required is long. [0003] There are also some 3D printers that use a steering gear (servo motor) to control a rotating arm with a fixed switch, and sequentially measure the Z-direction offset of the four corners of the printing plate relative to the center of the plate to obtain the inclination of the printing plate. Each position performs offset compensation on the Z direction to complete the automatic leveling function, but the biggest disadvantage of this method is high cost and slow movement.
