[0027] Working principle: When the utility model is in use, the staff places the glass to be coated with glue on the left suction cup 8 and fixes it by adsorption. Then, the T-shaped rod 13 is pulled out of the inner cavity of the positioning hole 15, and the glass is driven to rotate by rotating the movable shaft 2 and approach the glue coating head 30. Then, the vertical part of the T-shaped rod 13 is inserted into the inner cavity of the left positioning hole 15, and the glass is limited. The two first hydraulic push rods 5 are started to pull the annular tray 6 to move downward, and the square hole round tube 9 is driven to be sleeved on the outer wall of the square rod 19.

The delivery pump 33 can pump the glue in the glue storage barrel 32 into the glue coating head 30, and the side of the glass is glued. Gluing, and the servo motor 26 drives the threaded rod 28 to rotate, and the rotation of the threaded rod 28 drives the traction block 27 to move horizontally and longitudinally backward, so that the glue coating head 30 can be driven to move synchronously, and the glue liquid can be smeared on the side, and the electric telescopic rod 36 is started to drive the L-shaped scraper 37 to move, and the glue liquid on the side of the glass can be evenly smeared on the side of the glass with different thicknesses while the movable seat 29 moves.
