3D printer spray-head cleanliness detecting system

Abstract

The invention discloses a 3D printer spray-head cleanliness detecting system comprising n material storing tanks, n spray heads, a color storing unit, a color jet drawing unit, a color collecting unit, a spray head cleaning unit and a control unit. The control unit obtains original colors of printing materials in the m material storing tanks, and the printing materials in the m material storing tanks are extracted and sprayed out through the m spray heads corresponding to the m material storing tanks. The RGB value of a color image formed by the printing materials sprayed out by the spray heads is collected and then compared with the RGB value of the original colors, and then according to the comparison result, through instructions, the spray head cleaning unit is control to make action. According to the 3D printer spray-head cleanliness detecting system, the color image formed by the printing materials sprayed out by the spray heads is based, the RGB value of the color image is compared with the RGB value of the original colors, and thus the accuracy of colors of the printing materials sprayed out by the spray heads can be effectively judged from the difference between the two RGB values, so that when the situation that the spray heads are polluted is checked, the spray heads are cleaned and adjusted in time, and the cleanliness of the spray heads is ensured.

Description

technical field [0001] The invention relates to the technical field of nozzle function detection, in particular to a 3D printer nozzle cleanliness detection system. Background technique [0002] 3D printer is a machine of rapid prototyping technology. It is a technology based on a digital model file and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Using a 3D printer to print the model does not require traditional cutting machine tools and molds. Under the control of the computer, the 3D entity can be directly formed according to the 3D model of the workpiece. [0003] The nozzle is the part used to output consumables in the 3D printer. During the printing process, the nozzle is required to be able to move arbitrarily in space to deal with workpieces with different external contours; since the printing material is ejected from the nozzle, and when there is color printing, different The printing material of the co...

Problems solved by technology

[0003] The nozzle is the part used to output consumables in the 3D printer. During the printing process, the nozzle is required to be able to move arbitrarily in space to deal with workpieces with different external contours; since the printing material is ejected from the nozzle, and when there is color printing, different The printing material of the color will cause residue when it is sprayed from the nozzle. When using other colors, the original color will affect the currently used color, thus affecting the effect of 3D printing; even if each nozzle is set to spray a certain fixed color, After a long time of use, it will also cause the accumulation of printing materials, which will also affect the current color of the nozzle and reduce the effect of 3D printing
