[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Reference Figure 1-2 As shown, an embodiment of the utility model is provided: a vacuum rotary power suction cup, comprising a bracket 1, a motor 2 is arranged at the lower end of the right side of the bracket 1, the front end of the motor 2 is connected to the motor shaft 21, the motor shaft 21 passes through the bracket 1 and is arranged above the bracket 1, the motor shaft 21 is connected to a pulley 3, the pulley 3 is connected to a belt 4, the other end of the belt 4 is connected to a pulley 2 5, the pulley 2 5 is arranged on the left side of the bracket 1, the pulley 2 5 is arranged in a fixed frame 6, the fixed frame 6 is fixed to the upper surface of the left side of the bracket 1 by screws, a vacuum suction cup 7 is arranged on the left side of the bracket 1, one end of the vacuum suction cup 7 passes through the pulley 2 5 and is arranged below the bracket 1, and the other end of the vacuum suction cup 7 is arranged above the fixed frame 6, the motor 2 rotates, driving the pulley 1 3 to rotate, so that the pulley 1 3 drives the belt 4 and the pulley 2 5 to rotate together, so that the vacuum suction cup 7 rotates to achieve a more uniform drug solution on the wafer, and at the same time, the rapid rotation can accelerate the drying of the wafer.

[0016] Furthermore, the vacuum suction cup 7 includes a vacuum head 8, which is arranged below the bracket 1. A vacuum tube 9 is arranged above the vacuum head 8. The vacuum tube 9 passes through the bracket 1 and the fixed frame 6 and is clamped with the pulley 2 5. A suction cup 10 is arranged above the vacuum tube 9. The vacuum head 8, the vacuum tube 9 and the suction cup 10 are hollow inside. The vacuum head 8 is connected to an air pump for suction, so that a vacuum is achieved in the vacuum tube 9 and the suction cup 10, thereby fixing the wafer on the upper surface of the suction cup 10.

[0017] Furthermore, a circular hole 11 is provided on the upper surface of the suction cup 10 and is connected with the inside of the suction cup 10. A plurality of arc-shaped protrusions 12 are provided on the upper surface of the suction cup 10 in a circular array with the circular hole 11 as the center. An air duct 13 is formed between two adjacent arc-shaped protrusions 12 in front and back, and an air gap 14 is formed between two adjacent protrusions 12 in the left and right. The plurality of air gaps 14 are respectively connected with the circular hole 11 and the plurality of air ducts 13. The circular hole 11 is connected with the inside of the suction cup 10. After the wafer contacts the protrusion 12, the air duct 13 under the wafer is connected with the circular hole 11 through the air gap 14, so that the air duct 13 and the air gap 14 under the wafer also achieve vacuum, so that the wafer is more firmly fixed on the suction cup 10 and will not fall off under high-speed movement.

[0018] Furthermore, the belt 4 does not completely overlap with the pulley 1 3 and the pulley 2 5. The incomplete overlap between the belt 4 and the pulley 1 3 and the pulley 2 5 can be used to adjust the tension of the belt 4. The belt 4 may generate vibration and noise during operation. By making the belt 4 do not completely overlap with the pulley 1 3 and the pulley 2 5, the relative speed difference between the contact surfaces of the belt 4 and the pulley 1 3 and the pulley 2 5 can be reduced, thereby reducing the generation of vibration and noise.

[0019] Working principle: When using the equipment, the staff first places the wafer on the upper surface of the suction cup 10, and the vacuum head 8 is connected to the air pump to suck air to fix the wafer on the suction cup 10, and then the motor 2 is started. The rotation speed of the motor 2 is adjusted according to different working conditions. The rotation of the motor 2 drives the motor shaft 21 to rotate, and the motor shaft 21 drives the pulley 1 3 to rotate, the pulley 1 3 drives the belt 4 to rotate, and the belt 4 drives the pulley 2 5 to rotate. The vacuum tube 9 rotates together with the pulley 2 5, driving the upper suction cup 10 to rotate together, so that the drug liquid on the wafer is evenly distributed on the wafer. When the drug liquid is evenly distributed, the rotation speed of the motor 2 can be adjusted to make the wafer surface dry quickly.
