Deviation rectification frame of 3D printer, working method of deviation rectification frame and printer

Abstract

The invention relates to a deviation rectification device for a 3D printer. A cross beam is connected to sliders through deviation rectification devices arranged at the two ends, the sliders are arranged on a track, the sliders are driven by slider driving devices to move along the track, a lead screw is parallel to the track, the two ends of the lead screw are connected to the sliders through bearings, the lead screw is in threaded connection with a nut, a lead screw driving device drives the lead screw to rotate, and even though the nut moves along the lead screw, the cross beam is hinged tothe nut; and a displacement sensor includes a path strip arranged in parallel with the track and matched identification devices, and the identification devices are arranged at the two ends of the cross beam. By means of the deviation rectification device, a device for detecting synchronization is used for synchronizing the two sides when the two sides are not synchronized, and therefore synchronized driving of the two sides of the gantry printer is achieved.

Description

technical field [0001] The invention relates to the field of additive manufacturing equipment, in particular to a deviation correction frame for a 3D printer, a working method thereof, and a printer. Background technique [0002] At present, most of the driving methods of the motion system of 3D printing equipment use modules, linear motors and other driving methods. Due to the particularity of the structure of the 3D printing equipment itself and the implementation of the functions of each component, there is generally a gantry structure, such as a gantry printer. The entire printing The device is installed on a gantry frame, and because of the large span, the two sides are driven independently by the above-mentioned driving method. This structure has the problems of asynchronous driving on both sides and excessive resistance on one side, which is prone to deviation, torsion, etc. various problems. Contents of the invention [0003] Aiming at the deficiencies of the prio...
