Solder paste can be printed correctly on the PCB only when the position of the Mark point on the stencil is aligned with the position of the Mark point on the PCB. Therefore, accurate positioning of Mark points on PCB boards and stencils plays an important role in the workflow of fully automatic printing machines. The equipment is equipped with an image mechanism to align the position of the Mark point on the PCB board and the screen board. The PCB board is placed on the network adjustment platform, and the screen board is placed on the network adjustment frame. In order to align the positions between the two, it is necessary to adjust both The distance between the two vertical directions on the horizontal position and the angle between the two.

In the working process, in a Three adjustment actions need to be completed on the equipment, which will lead to the disadvantages of low network adjustment accuracy and low efficiency. The setting of the three adjustment action mechanisms together often easily causes the action interference between equipment and causes the problem of low adjustment accuracy.
