The conveyor belt mechanism a2 is located at the upper end of the conveyor belt mechanism b4. The outer periphery of the conveyor belt of the conveyor belt mechanism b4 is bonded with a sponge conveyor belt 5. The sponge conveyor belt 5 is made of flexible material and can prevent the glass from being damaged.

The material picking mechanism is installed on the waste box 6 for tearing off the film bonded to the tape 20.

The winding roller b82 is detachably mounted between the two mounting seats 7. Two limiting rings 13 are arranged side by side on the winding roller a81 and the winding roller b82.

[0031] An infrared transmitter 16 and an infrared receiver 17 are respectively installed at both ends of the gantry 14. When the infrared rays emitted by the infrared transmitter 16 pass through the gap between two adjacent placement plates 3 and are received by the infrared receiver 17, the infrared receiver 17 feeds back the signal to the controller 9, and the controller 9 controls the conveyor belt mechanism a2 to stop driving, thereby realizing the precise positioning of the glass.

[0032] Multiple pieces of glass to be torn off are placed on multiple placement plates 3 in turn, and the conveyor belt mechanism a2 conveys multiple pieces of glass. When the glass moves to the position below the pressure plate 18, the controller 9 controls the linear drive mechanism a15 to drive the pressure plate 18 to move downward, driving the sticky side of the tape 20 to adhere to the film on the glass. As the glass continues to move, the film on its surface is gradually torn off, and then the power component is set to drive the winding roller a81 to rotate, thereby realizing the winding of the tape 20. When the film is placed on one side of the material taking mechanism, the material taking mechanism removes the waste film adhered to the tape 20. When the placement plate 3 rotates downward, the glass in its positioning groove falls onto the conveyor belt mechanism b4 and is transported away, thereby realizing the function of automatic unloading.
