Printing head state detection method, printing head detection system and three-dimensional printer

Abstract

The invention relates to a printing head state detection method, a printing head detection system and a three-dimensional printer. The three-dimensional printer comprises the printing head detection system. The printing head state detection method comprises the following steps that the printing head prints test paper according to preset specification; a print image of the printed test paper is acquired; noise reduction processing is carried out on the print image; a plurality of detection areas are selected from the print image subjected to noise reduction processing; the total number of printlines of the detection areas is counted; the total number of the print lines of each detection area is compared with the total number of preset qualified lines; and whether the printing head needs tobe maintained or replaced is judged according to the comparison result. According to the printing head state detection method, the printing head detection system and the three-dimensional printer, the automatic detection can be achieved, and therefore the printing head state detection efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of image detection, in particular to a print head state detection method, a print head detection system and a 3D printer. Background technique [0002] At present, 3D printing technology has a high reputation both domestically and internationally, and the production of 3D printing production equipment has been quantified. With the increasing number of equipment, equipment debugging and status detection have become a major problem in equipment maintenance. The state detection of the 3D printer print head in the prior art is basically manual and manual visual inspection to determine whether the print head is in a normal state and needs to be replaced. In this process, professional testing personnel are required to perform testing, which not only has large testing errors, but also consumes a lot of testing time. For a long time, it requires a huge labor cost. SUMMARY OF THE INVENTION [0003] Based on this, ...
