[0045] See Figures 3 to 5The glue dispensing mechanism 4 has a glue dispensing frame 41, a moving unit 42, a rotating lifting mechanism 43, and a glue dispensing unit 44. The glue dispensing frame 41 has a bottom plate 411 and a mold platform 412 arranged above the bottom plate 411. The glue dispensing frame 41 is used to place and set up the overall device.

[0046] The rotating lifting mechanism 43 includes a rotating device 431 and a lifting device 432. The rotating device 431 is used to adjust the horizontal angle of the lifting device 432 so that the upper top block 434 is aligned with the overlapped gap position of the long strip through slot 4121 and the glue separation slot 4411, which is convenient for the upper top block 434 to split the rubber sheet.

The moving unit 42 is a linear module.

[0049] The working principle of the present invention is as follows: after the rubber sheet is placed on the mold platform 412, the mold platform 412 presses the rubber sheet, the bottom moving unit 42 moves the rubber dispensing unit 44 to the specified position, the rotating lifting mechanism 43 realizes deviation correction, and then the lower pressure plate 441 presses the rubber sheet, and the upper lifting block 434 separates and lifts the rubber strips upward through the gap, and then the rubber dispensing unit 44 pushes the rubber strips out of the long strip through groove 4121 of the mold platform. The entire rubber dispensing process is fully automated, which improves efficiency and saves labor. The number of rubber dispensing can be changed by changing the number of slots inside the mold platform, which can be compatible with more usage scenarios.

[0050] The general flow process of the present invention is loading materials into the material warehouse, transferring the sheet glue by the material transfer robot, distributing the glue by the glue distributing mechanism, and sticking the glue by the robot.

[0051] Action flow: After manual loading, the material transfer robot 3 grabs the sheet of glue from the loading warehouse 2 to the centrifugal paper tearing position to tear off the centrifugal paper, and then goes to the glue separation mechanism 4 for glue separation. After the glue separation is completed, visual photography is used for correction, and the glue sticking robot 5 completes the glue sticking.

[0052] The multi-position loading warehouse 2 can realize loading without stopping the machine. When the rubber sheets in one of the loading warehouses 2 are used up, the robot goes to another loading warehouse 2 to grab materials, and the empty loading warehouse 2 continues to be replenished, which saves the downtime and waiting time and improves efficiency. After the robot grabs a layer of rubber sheets each time, the bottom elevator rises one layer, ensuring that the robot's grabbing position is at the same height each time, simplifying the robot's program and facilitating operation.

[0053] Glue dispensing mechanism 4: After the rubber sheet is placed on the glue dispensing platform, the mold platform 412 presses the rubber sheet, and the moving unit 42 moves the rotary lifting mechanism 43 and the glue dispensing unit 44 to the specified position. The rotary lifting mechanism 43 realizes deviation correction, and then the upper ejector block 434 ejects the rubber strip from the long strip through groove 4121 of the mold platform 412. The entire glue dispensing process is fully automated, which improves efficiency and saves labor. Example 2

When working, the external vacuum device is started, so that the adsorption holes 4122 generate negative pressure suction, adsorbing the sheet rubber on the surface of the mold platform 412, and preventing the sheet rubber from moving at will.

[0055] The moving unit 42 includes a driving motor 421, the driving end of the driving motor 421 is connected to a screw nut assembly 422, the screw nut assembly 422 includes a screw 4221 and a screw nut 4222, the screw nut 4222 is sleeved on the screw 4221, and the top end is fixed to the rotating jacking mechanism 43.
