Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] like figure 1 and figure 2 As shown, the fully automatic leveling device for the 3D printer tray in this embodiment includes three lead screws 02 arranged on the fixed frame 01 and parallel to the Z axis. The lead screw nut 03 of each lead screw is embedded in the support frame 04, and the support frame 04 Upper fixed tray 05;

[0027] Fixing frame 01 comprises the parallel horizontal fixing ring 11 of upper floor and lower floor, vertical four columns 12, and horizontal fixing ring 11, and the inner and outer contours of horizontal fixing ring 11 are similar regular pentagons. The second, third, and fourth apex positions are opened with a column through hole 13, and the lead screw through hole 14 is opened at the fifth apex position, the midpoint position of the first and second apexes, and the midpoint position of the third and fou...

Abstract

A full-automatic bed leveling device for a 3D printer comprises a bed, a moving mechanism fixed with an infrared distance measurement sensor and a nozzle, a fixed frame, a plurality of parallel lead screw pairs and supporting stepper motors, wherein the moving mechanism drives the nozzle to move horizontally in the fixed frame; the stepper motors drive the lead screw pairs fixed in the fixed frame to move and drive a borne bed to move vertically; the center of gravity of the bed is close to or coincides with the center of a limited plane of the fixed frame and approaches the boundary of a figure defined by the lead screw pairs. According to the full-automatic bed leveling device for the 3D printer, the parallel degree of a bearing surface of the bed stepping along a Z axis is measured in due time by the moving mechanism moving on an X-Y-axis horizontal surface, tiny errors among support mechanisms during stepping along the Z axis are obtained through multi-point measurement, and adjustment is performed timely, so that parallel errors cannot be accumulated. Deviation of the surface height in a consumable curing process is avoided, and the printing accuracy is guaranteed. The invention further provides a full-automatic leveling device.

Description

technical field [0001] The invention designs a horizontal adjustment structure of a material platform, in particular relates to a horizontal adjustment structure of a printer consumable bearing platform. 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 fixed frame is provided with a moving mechanism that can step point by point along the X-axis and Y-axis in the horizontal plane. The lower end surface of the moving mechanism is equipped with a nozzle. The moving mechanism can perfectly complete the point-by-point positioning of the nozzle in the XY-axis horizontal plane. [0003] The tray used to carry the adhesive material (consumables) that is cured layer by layer needs to be displaced stepwise along the Z-axis along with the curing process. In the existing 3D printer structu...
