The turntable 1 is used to carry multiple film tearing station assemblies and rotates under the drive assembly to ensure that the plate to be processed 6 reaches the film tearing station and the material taking station in turn. The workbench 3 is used to carry each assembly to ensure normal operation. The circular holes 11, the exhaust pipe 17, the exhaust pipe 2 18 and the vacuum pump 7 make the plate to be processed 6 tightly attached to the top of the hollow plate 9 to ensure the stability of the plate to be processed 6 when tearing the film. The limit column 10 is used to place the plate to be processed 6 in a suitable position on the hollow plate 9.

[0036] Reference Figure 1 - Figure 6 The fixing assembly includes an L-shaped block 13, which is fixedly connected to both sides of the hollow plate 9. A plurality of fixing blocks 16 are fixedly connected to the top of the turntable 1. A trapezoidal latch 14 is slidably connected inside the fixing block 16. The top of the trapezoidal latch 14 is fixedly connected to a connecting column 12. A spring 15 is sleeved on the outside of the connecting column 12. The L-shaped block 13 is used to connect the hollow plate 9. The fixing block 16 is used to carry the various components inside it to ensure normal operation. The L-shaped block 13 is inserted into the fixing block 16, and the trapezoidal latch 14 is then inserted into the L-shaped block 13 to achieve the fixation between the hollow plate 9 and the turntable 1. The connecting column 12 is used to connect the trapezoidal latch 14 to ensure that the trapezoidal latch 14 can be pulled. The spring 15 is used to be tightly inserted into the L-shaped block 13 without external force.

[0037] Reference Figure 1 - Figure 6 The driving assembly includes a motor 8 and a vacuum pump 7. The output end of the motor 8 is fixedly connected to the bottom of the turntable 1. The output end of the vacuum pump 7 is fixedly connected to an exhaust pipe 18. The end of the exhaust pipe 18 away from the vacuum pump 7 is fixedly connected to a rubber ring 20. The motor 8 is the power source for the rotation of the turntable 1. The vacuum pump 7 is used to vacuum the hollow plate 9, thereby fixing the plate to be processed 6. The rubber ring 19 cooperates with the rubber ring 20 to ensure the airtightness of the connection between the exhaust pipe 17 and the exhaust pipe 2 18.

[0038] Reference Figure 1 - Figure 3 The film tearing assembly includes a film tearing robot arm 2, which is fixedly connected to the outside of the workbench 3. The film tearing robot arm 2 is used to tear off the film 4 to be torn.

[0039] Reference Figure 1 - Figure 3The material taking component includes a material taking robot arm 5, which is fixedly connected to the outside of the workbench 3. The material taking robot arm 5 is used to remove the plate to be processed 6 after the film is torn off.

[0040] Working principle: first, place the plate to be processed 6 within the limit column 10 on the hollow plate 9, and drive the turntable 1 to rotate through the motor 8. When the turntable 1 rotates with a hollow plate 9 to the bottom of the film-tearing robot arm 2, the exhaust pipe 1 17 at the bottom of the hollow plate 9 will just abut against the exhaust pipe 2 18 on the vacuum pump 7, and then the hollow plate 9 will be vacuumed. Since there are multiple circular holes 11 on the hollow plate 9, the plate to be processed 6 will be tightly adsorbed on the surface of the hollow plate 9 until the film-tearing robot arm 2 tears off the film 4 to be torn off, and the turntable 1 will rotate away until it is under the material-taking robot arm 5, and then the material-taking robot arm 5 will take away the plate to be processed 6 with the torn film, which effectively prevents the plate to be processed 6 from being unstable when tearing the film, which makes it difficult to tear the film. When tearing the film of the boards 6 to be processed of different sizes, the connecting column 12 can be pulled, and the trapezoidal pin 14 is pulled, and the spring 15 is compressed until the trapezoidal pin 14 is pulled out of the L-shaped block 13, so that the L-shaped block 13 can be pulled out from the fixed block 16, and then the hollow plate 9 is removed, and then the L-shaped blocks 13 on both sides of the appropriate hollow plate 9 are directly inserted into the fixed block 16. During the insertion process, when the trapezoidal pin 14 is contacted, the trapezoidal pin 14 will be squeezed open until the L-shaped block 13 is completely inserted into the fixed block 16. Under the action of the spring 15, the trapezoidal pin 14 will be inserted into the L-shaped block 13, and then the hollow plate 9 is fixed, which effectively solves the problem of tearing the film of the boards 6 to be processed of different sizes and improves work efficiency.
