The left and right adjustment of the position of the plate material can be achieved by providing a side pushing structure, such as a cylinder, a push plate, etc., at the two feeding side tables 300. After the adjustment is completed, the supporting wheel lifting driver 120 can drive the supporting wheel frame 110 to descend, so that the normal movement of the plate is prevented from being influenced.
Specifically, the screen printing machine for preventing the plate from sagging further comprises a vision module 800 and a screen printing module 900, wherein the vision module 800 is positioned above the feeding side table 300 and is used for visually detecting the shape and the position of the plate, and the screen printing module 900 is positioned above the screen printing table 200 and is used for screen printing the plate. In particular, the vision module 800 may be a vision camera or the like.
Specifically, the silk screen module 900 is provided with an adjusting screen frame and a long handle adjusting assembly, and a user can finely adjust the shape and position of the screen frame through the long handle adjusting assembly.
The screen printing machine for preventing the plate from sinking can be suitable for screen printing of the plate of the circuit board, and is particularly suitable for screen printing of the plate of the flexible circuit board. It will be appreciated that the present utility model prevents sagging of the sheet material and may also be used for printing of ordinary sheet material, and those skilled in the art may specifically configure the present utility model according to actual needs.
