When the bottom surface of the sealing cover 25 just contacts the sealing strip, the electric telescopic rod 19 is stopped, and the electric heating plate is started to heat the EVA film. The external exhaust device is started to extract the air in the sealing cover 25 and the cavity of the support plate 3 through the exhaust pipe.

At this time, the pressure plate 24 is resisted by the back plate and no longer moves down. The buffer spring between the first disc 20 and the second disc 22 is further compressed. The electric telescopic rod 19 can further drive the L-shaped transmission plate 28 to move down synchronously, and the spur gear 33 is driven to rotate through the cooperation of the slide plate 29, the oblique connecting plate 30 and the rack 32. The spur gear 33 drives the turntable 4 to rotate, and the turntable 4 drives the L-shaped plate 5 to continue to move inward through the vortex plate 6. The resistance block 10 no longer moves due to the resistance of the glass plate and the back plate, and the first reset spring will be compressed. During the movement of the L-shaped plate 5, the two scrapers 17 drive the rotating rod 16 to rotate under the resistance of the glass plate and the side of the back plate to scrape off the leaked glue in the gap between the glass plate and the back plate.
