This arrangement makes it impossible for the sliding blocks 5 to detach from the sliding grooves 4. With the help of this structure, the sliding seat 6 can be suspended, and then The threaded column 3 can better complete the sliding control work of the sliding seat 6. The two sliding blocks 5 are fixedly connected with the sliding seat 6 on one side wall away from the two sliding grooves 4. The two sliding seats 6 are provided with threaded openings 7. The two threaded columns 3 are respectively threadedly connected to the two threaded openings 7. The two sliding seats 6 are fixedly connected with a clamping seat 8 on one side wall away from the two sliding blocks 5.

The two clamping seats 8 are fixedly connected with a fixed clamping block 9 on one side wall close to each other, and the two clamping seats 8 are provided with a separation component.

[0023] The separation component includes a working chamber 10 arranged in the clamping seat 8, a sliding opening 11 is provided on the inner wall of the working chamber 10 on the side away from the sliding seat 6, a sliding frame 12 is slidably connected in the sliding opening 11, an auxiliary seat 13 is fixedly connected to a side wall of the sliding frame 12 away from the working chamber 10, an auxiliary clamping block 14 is fixedly connected to a side wall of the auxiliary seat 13 close to the fixed clamping block 9, a threaded tube 31 is fixedly connected to a side wall of the auxiliary seat 13 away from the auxiliary clamping block 14, a threaded strip 32 is threadedly connected in the threaded tube 31, the threaded strip 32 is arranged directly opposite to the clamping seat 8, and a turntable 16 is fixedly connected to one end of the threaded strip 32 away from the clamping seat 8, with the help of the threaded strip 32, the lifting range of the auxiliary seat 13 can be effectively controlled, so that the auxiliary clamping block 14 can cooperate with the fixed clamping block 9 to complete the processing of masks of different specifications, a lifting disk 15 is slidably connected in the working chamber 10, and the lifting disk 15 is arranged close to the sliding seat 6 A lifting spring 17 is fixedly connected to one side wall of the lifting plate 15 close to the sliding seat 6, and one end of the lifting spring 17 away from the lifting plate 15 is fixedly connected to the inner wall of the upper end of the working chamber 10. A power supply component 18 is provided on one side outer wall of the clamping seat 8, and a power supply line 19 is provided on the power supply component 18. One end of the power supply line 19 away from the power supply component 18 passes through the clamping seat 8 and is arranged on the lifting spring 17. A connecting groove 20 is provided on one side wall of the lifting plate 15 away from the lifting spring 17, and a connecting block 21 is slidably connected in the connecting groove 20. The connecting groove 20 is arranged in a T shape, and the connecting block 21 is also arranged in a T shape. The shape of the connecting block 21 is matched with the connecting groove 20, and the end of the connecting block 21 away from the connecting groove 20 is fixedly connected to the sliding frame 12. In this way, the deformation of the lifting spring 17 can be controlled by energizing the power supply component 18 and the power supply line 19, so that the control work of the second mask can be completed;

[0024] The working chamber 10 is also provided with an auxiliary component, which includes a plurality of jet holes 22 arranged on the inner wall of the working chamber 10 on one side close to the fixed clamping block 9, a working spring 23 is fixedly connected to a side wall of the working chamber 10 away from the plurality of jet holes 22, and one end of the working spring 23 close to the plurality of jet holes 22 is fixedly connected to a working plate 24, and the working plate 24 is arranged in close contact with the sliding frame 12, and a limiting hole 25 is also provided on a side wall of the working chamber 10 away from the plurality of jet holes 22, and a limiting rod 26 is slidably connected in the limiting hole 25, and one end of the limiting rod 26 is fixedly connected to the working plate 24, and a side wall of the working chamber 10 away from the plurality of jet holes 22 is provided An air inlet 27 is arranged directly opposite to the working plate 24. A connecting pipe 28 is fixedly connected to the outer wall of the clamping seat 8 on one side away from the multiple air jet holes 22. The connecting pipe 28 and the air inlet 27 are interconnected. The connecting pipe 28 is made of a hose material. A jet pump 29 is arranged on the upper end surface of the grabbing plate 1. Two jet pipes 30 are arranged on the jet pump 29. One end of the two jet pipes 30 away from the jet pump 29 is respectively fixedly connected to the two connecting pipes 28. The two jet pipes 30 are respectively interconnected with the two connecting pipes 28, so that the clamping and loosening processing work can be completed with the help of jets, and the mask is easier to separate with the help of airflow.

[0025] During the use of the present invention, the robot arm directly controls the grabbing plate 1 to move to the specified position, so that the grabbing plate 1 is aligned with the corresponding mask stack. At this time, the two fixed clamping blocks 9 are respectively located on both sides of the mask stack, and the two fixed clamping blocks 9 will be aligned with the top mask. At this time, the jet pump 29 sprays air to the two connecting pipes 28 through the two jet pipes 30, and then sprays air into the two working chambers 10 through the air inlet 27. The air flow entering the working chamber 10 can push the working plate 24 to overcome the elastic force of the working spring 23 to slide, and then push the sliding frame 12 to slide in the sliding port 11, so that the auxiliary seat 13 and the auxiliary clamping block 14 can be pushed to the position aligned with the fixed clamping block 9. At this time, the power supply component 18 supplies power to the lifting spring 17 through the power supply line 19. When the lifting spring 17 is energized, it contracts under the action of the magnetic field, and then drives the sliding frame 12 and the auxiliary seat 13 to rise to the specified position, so that the auxiliary clamping block 14 is close to the fixed clamping block 9, and the distance between the auxiliary clamping block 14 and the fixed clamping block 9 is consistent with the distance between the two stacked masks.

[0026] Here, the staff can adjust the distance between the two masks after stacking the masks according to the specifications of the masks to be processed before starting the work, and rotate the threaded strip 32 to make the threaded strip 32 rotate and rise in the threaded tube 31, so that the upper end of the threaded strip 32 can be lifted and lowered to a suitable position. When the auxiliary seat 13 is subsequently lifted and lowered, the threaded strip 32 can be used to press against the clamping seat 8 to make the auxiliary seat 13 accurately stay at a suitable height, and then the auxiliary clamping block 14 can smoothly cooperate with the fixed clamping block 9 to complete the processing of masks of different specifications. When the device is subsequently clamping, the dual-axis motor 2 can control the two threaded columns 3 to rotate, and the threaded connection between the threaded column 3 and the threaded port 7, and the sliding seat 6 is restricted by the sliding block 5 and the sliding groove 4 and cannot rotate, so that the two sliding seats 6 are close to each other, and then the fixed clamping block 9 and the auxiliary clamping block 14 are driven to approach each other, and the clamping work of the first mask and the second mask is completed, and then the robotic arm controls the entire device to rise;

[0027] At this time, the power supply component 18 stops supplying power, the lifting spring 17 loses power and no longer contracts, but stretches under the action of its own elastic force, so that the auxiliary seat 13 and the clamping seat 8 tend to move away from each other. When the clamping seat 8 rises with the grab plate 1, the auxiliary seat 13 will stay in place, and then the second mask clamped by the auxiliary clamping block 14 will stay in place. At the same time, since the air entering the working chamber 10 can be ejected through the jet hole 22 and then sprayed into the gap between the two masks, the two masks can better complete the separation work, further ensuring the smooth completion of the clamping work of a single mask, and then ensuring the quality and efficiency of the production and processing work. Subsequently, after a period of rising work, the jet pump 29 stops working, so that the working plate 24 that loses the air push can be reset under the elastic force of the working spring 23, so that the sliding frame 12 of the driving force can no longer push the auxiliary seat 13 and the auxiliary clamping block 14 to clamp the second mask, and the device can complete the separation work from the second mask when it continues to rise, so that the subsequent work of the device can be completed smoothly.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
