When electronic panels such as touch panels or circuit boards perform circuit printing operations, the electronic panels are first placed on the horizontal work platform on the surface of the workbench, and a screen is placed on the surface of the electronic panel, and then the metal ink is poured. Enter into the screen, and move the printing machine to the upper side of the screen through the traverse device installed on the workbench, and then use the two lifting devices of the printing machine (such as pneumatic cylinders or motors) to control the ink scraping. The second plate is lowered relative to the outside and pressed against the screen, so that the ink squeegee is attached to one side of the screen for the subsequent traverse device to make the ink squeegee print the metal ink back and forth on the surface of the screen to make the screen The ink can be printed on the surface of the electronic panel through the through holes on the mesh surface to complete the circuit printing of the electronic panel Brush job.

In the circuit printing operation of the aforementioned electronic panel, if the ink squeegee and the electronic panel are not parallel to each other, it will cause the ink squeegee to descend and contact the screen slantingly, and then the ink squeegee will move back on the surface of the screen The metal ink on the screen cannot be uniformly printed on the surface of the electronic panel. Therefore, adjusting the angle of the ink squeegee to form a parallel state between the ink squeegee and the electronic panel becomes an indispensable part of the operation.
