Detailed description of the invention
It is described to various aspects of the present invention in conjunction with example with reference to the accompanying drawings.
The invention discloses a kind of method testing 3D equipment printhead.Figures 1 and 2 show that the optional layout of one of the printhead that the present invention adopts, for the ease of illustrating, be described for this printhead after the present invention, it should be understood that, this printhead is only example, and it does not limit the invention, and the method for the present invention can carry out with other printheads.
Referring to Fig. 1 and Fig. 2, printhead having at least one jet head sets, in the embodiment shown in fig. 1, illustrate 4 jet head sets being made up of 12 shower nozzles altogether, each jet head sets includes three shower nozzles, is wherein constituted a jet head sets by shower nozzle 1,2,3.Shower nozzle 1,2,3 arranges and parallel alignment each other along the Y-direction shown in figure.Referring to Fig. 2, each shower nozzle in jet head sets has the multiple spray orifices along the X-direction arrangement vertical with Y-direction, and these spray orifices illustrate with intensive point in fig. 2.Figure also show other multiple jet head sets, for instance the jet head sets at shower nozzle 4 place, each jet head sets has identical layout.As it is shown in figure 1, these jet head sets can interlaced arrangement on the print head, and the projection that the ink-jet scope of adjacent jet head sets is in the plane being perpendicular to described Y-direction is mutually linked, and printhead can all be covered by overall ink-jet scope through region.Therefore, when printhead normal operation, it is possible to print the unremitting straight line of shown in label 1 in Fig. 3 on test paper.
Before carrying out printing test, first have to select printing test paper.What printhead sprayed in process of production is special liquid, and therefore printing test paper is wanted to clearly indicate for being sprayed on special liquid thereon.Through investigation, meeting now requirements above on the market and widely used printing test paper is thermal printing paper, therefore thermal printing paper selected by test paper used, it should be appreciated that may be used without other printing papers, thermal printing paper is only preferred version.
In the solution of the present invention, owing on shower nozzle, spray orifice is very intensive, the ink-jet effect of adjacent orifices can interfere, therefore spray orifice on each shower nozzle is divided into again two groups (odd number group, even number set).
Judge whether printhead can be used, need to test its overall ink-jet effect (whether having gap between the effect of Multi folds coverage ink-jet and horizontal each shower nozzle ink-jet scope), understand printhead ink-jet situation in time, printhead is carried out maintaining, also need to test the ink-jet situation of each shower nozzle, therefore, printhead entirety ink-jet situation should be detected, detect the ink-jet situation of each shower nozzle again.
