Problems solved by technology
Since the printing accuracy is calculated in micron units, it is far from accurate identification by hand touch
When setting parameters, there are great differences in the settings of different operators, and the same operator also has great differences in each setting; that is, there are great differences in reproducibility and repeatability, resulting in unstable quality of printed products

The invention relates to a method for setting a zero reference for the clearance between a silk-screen printing template and a worktable. In the method, a laser sensor is used for accurate measurement, namely the position where the silk-screen printing template and the fixed worktable come into contact upon the observation of the change of data on the displayer while operation equipment lowers the lifting worktable after the displayer of the laser sensor is zeroed is set as the zero reference. The method improves the situation that the zero point positioning is performed simply according to the handfeel of an operator as the clearance between the silk-screen printing template and the worktable cannot be measured accurately. The laser sensor of the invention is fixed on the surface of a printer by a bracket and a magnetic surface seat, and when the silk-screen printing template lifts, the laser sensor performs non-contact measurement without causing deformation of the silk-screen printing template, so the accuracy of the non-contact measurement is higher than contact measurement. In the invention, through accurate zero reference positioning, the accuracy of a printing height setting parameter is improved effectively and the quality of printed products is assured. The method is simple, quick and obvious in effect.
Description
technical field [0001] The invention relates to a method for setting the position of a screen printing template, in particular to a method for setting the zero reference of the gap between the screen printing template and a workbench by using a laser sensor. Background technique [0002] At present, in screen printing, the parameters that affect the printing thickness, printing pressure and printing speed can be accurately set, only the distance between the screen printing template and the workbench is set, there is a big difference, it is difficult to control . Now when determining the zero reference position of the formwork, it often depends on the operator's experience to feel whether the formwork is in contact with the workbench and the degree of contact with the hand. Since the printing accuracy is calculated in micron units, it is far from accurate identification by hand touch. When setting parameters, different operators have great differences in settings, and the s...
