Embodiment 1

[0038] Such as Figure 4 As shown, the left and right motors move in the same direction at the same speed. For example, 1) when the left and right motors rotate clockwise at the same time, and the speed is the same, the print head moves along the negative direction of the X axis; 2) when the left and right motors rotate counterclockwise at the same time, and the speed is the same , the print head moves along the positive direction of the X axis.

[0039] When the left and right motors move in the same direction and at the same speed, the synchronous belt 5 makes a circular motion, and the two auxiliary wheels 2 on the same side of the Y axis rotate in the opposite direction at a constant speed driven by the synchronous belt, so the X guide rod remains stationary in the Y direction; The two auxiliary wheels 2 on the same side of the X axis rotate at the same speed and in the same direction, so the print head moves in the X direction. Because the print head is associated with t...

Embodiment 2

[0041] Such as Figure 5 As shown, the left and right motors move in opposite directions at the same speed. For example, 3) when the left motor rotates counterclockwise and the right motor rotates clockwise, and the speeds are the same, the print head moves in the negative direction of the Y axis; 4) when the left motor rotates clockwise When it rotates clockwise and the right motor rotates counterclockwise, and the speed is the same, the print head moves forward along the Y axis.

[0042] When the left and right motors move in the opposite direction at the same speed, the two motors and the driven wheel respectively form a constant speed reverse circular motion. At this time, the auxiliary wheel does not rotate, the print head remains stationary in the X direction, and the X guide rod moves in the Y direction. Same with motor turning inside and out.

Embodiment 3

[0044] Such as Figure 6 As shown, the left and right motors rotate at different speeds. For example, 5) when the left motor rotates clockwise and the right motor stops rotating, the print head moves at 45° along the negative direction of the X axis and the positive direction of the Y axis; 6) when the left motor rotates When the right motor rotates counterclockwise and the right motor stops, the print head moves along the positive direction of the X axis and the negative direction of the Y axis at 45°; 7) When the right motor rotates clockwise and the left motor stops rotating, the print head moves along the negative direction of the X axis , Y-axis moves at 45° in the negative direction; 8) When the right motor rotates counterclockwise and the left motor stops rotating, the print head moves at 45° along the X-axis positive direction and the Y-axis positive direction; when the left motor and the right motor respectively When rotating in different directions and at different s...

Abstract

The invention discloses an X-Y axis linkage device and linkage method of a 3D printer. The device comprises motors, a support, synchronizing wheels, auxiliary wheels and a synchronizing belt. The synchronizing wheels and the auxiliary wheels are located on the support. The synchronizing wheels comprise two driving wheels and two driven wheels. The synchronizing belt is wound into an H shape through the four synchronizing wheels and the four auxiliary wheels. The two ends of a fracture of the synchronizing belt are fixed to the two sides of a printing head seat. The motors comprise the left motor and the right motor. An output shaft of the left motor and an output shaft of a right motor are connected with the driving wheels respectively and drive the same synchronizing belt. The synchronizing belt wound into the H shape is driven by the two motors at the same time, X-Y axis linkage of the 3D printer is achieved, the overall printing quality of the 3D printer is improved, the equipment structure is more compact, and equipment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and in particular relates to an XY-axis linkage device and a linkage method of a 3D printer based on the FDM principle. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. The materials of the melt extrusion molding (FDM) process are generally thermoplastic materials, such as wax, ABS, PC, nylon, etc., which are fed in filament form. The material is heated and melted in the nozzle. The nozzle moves along the section profile and filling trajectory of the part, while extruding the molten material, which solidifies rapidly and bonds with the surrounding materials. Each layer is accumulated on the previous layer, and the previous layer plays a role in positioning and supporting the current layer. As the ...
