Embodiment Construction

[0064] The leveling mechanism of the present invention will be further described below in conjunction with the accompanying drawings.

[0065] Such as Figure 8-9 As shown, the leveling mechanism includes a fixed base 1 , a radiator 2 , a rotating arm 4 , a micro switch 10 , a magnet 5 , a heating block 3 , a nozzle 9 , and a fan 7 . The aperture of the fixing seat 1 runs through up and down, and the upper surface is designed with a square protrusion, which is used for the installation and positioning between the entire leveling mechanism and the effector. The fixed component is the fixed seat 1, which runs through up and down, and the through hole is used to install the radiator 2, and there is a section of coaxial small-diameter hole on the upper surface of the through hole, which is used as a radiator installation limit. The lower end of the radiator is equipped with a heating block 3 and a shower nozzle 9, both of which are lower than the fixed seat. The fixing seat 1 ru...

Abstract

The invention belongs to the technical field of three-dimensional printing, and specifically relates to a feedback type automatic leveling method for a parallel arm three-dimensional printer, which is characterized in that: the sensor collects the height data of the test points in the printing platform, and performs feedback multi-stage limit Origin compensation to realize the leveling of the printer. It specifically includes the following steps: determining the target threshold and leveling order; collecting data for the first-order leveling; determining the origin compensation value of each tower; adjusting the first-order virtual origin plane; second-order leveling; completing multi-level leveling. The present invention provides a set of feedback-type automatic leveling method for parallel arm three-dimensional printers, through compensation and adjustment of the origin positions of the towers of the parallel three-dimensional printers, that is, adjusting the position of the virtual origin plane formed by the origin positions of the towers to achieve leveling. The method facilitates and automates the leveling work of the printing platform, improves the leveling efficiency and ensures the product quality.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional printing, and relates to a feedback-type automatic leveling method for a parallel-arm three-dimensional printer, in particular to a feedback-type multi-stage automatic leveling method for origin compensation by collecting height data of printing platform test points through sensors. Background technique [0002] For 3D printing, whether the first layer of printing can be evenly and firmly attached to the printing platform determines the success of the printing job. If the nozzle is too low, extrusion will be difficult; if it is too high, it will lead to weak bonding or even spinning in the air. The reason for this phenomenon is largely due to the substandard leveling results of the printer. Therefore, the leveling of the 3D printer is particularly important. [0003] Part of the existing 3D printer leveling technology is manual leveling, such as a leveling method published by Wang Dajun...
