At this time, the glass product will be placed on the two silicone buffer pads 28, and the front edge of the glass product will be pressed against the reference baffle 33. Then the vertical drive motor 21 will be started. The vertical drive motor 21 will drive the vertical screw 22 to rotate. The vertical screw 22 will drive the lifting hollow pressure plate 23 to move downward. When the vacuum suction cup 25 fully contacts the upper surface of the glass, the negative pressure generator 24 will be started, so that the vacuum suction cup 25 firmly adsorbs and fixes the glass product.
