Abstract

The invention relates to a printing head state detection method, a printing head detection system and a 3D printer. The 3D printer includes the print head detection system, and the print head state detection method includes the following steps: the print head prints test paper according to preset specifications; obtains a print image of the print test paper; performs noise reduction processing on the print image Select a number of detection areas for the print image after noise reduction processing; count the total number of print lines in each detection area; compare the total number of print lines in each detection area with the total number of preset qualified lines; judge whether the print head needs to be repaired or not according to the above comparison results replace. The print head state detection method, the print head detection system and the 3D printer can realize automatic detection, thereby helping to improve the print head state detection efficiency.

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 inspection have become a major problem in equipment maintenance. The detection of the state of the print head of the 3D printer in the prior art is basically a manual and manual detection with the naked eye to determine whether the state of the print head is normal or whether it needs to be replaced. In this process, professional inspectors are required to perform detection, which not only has a large detection error, but also consumes a lot of energy. For a long time, it requires a huge human cost. Contents of the in...
