The end of the output shaft of the servo motor 1 is connected to the end of the double-headed ball screw 10. In some embodiments of the present application, the output shaft of the servo motor 1 is connected to the end of the double-headed ball screw 10 through a synchronous structure 1. The synchronous structure 1 includes a synchronous wheel 1 fixedly connected to the end of the output shaft of the servo motor 1, a synchronous wheel 2 fixedly connected to the end of the double-headed ball screw 10, and a synchronous belt 1. The synchronous wheel 1 and the synchronous wheel 2 are connected through a synchronous belt 1. When the servo motor 1 is working, the servo motor 1 can drive the double-headed ball screw 10 to rotate.

[0030] The outer rings at both ends of the double-ended ball screw 10 are threadedly connected with ball nuts, and the ball nut is fixedly connected to the movable clamp 6. When the double-ended ball screw 10 rotates, the ball nut threadedly connected thereto can move in the direction of the double-ended ball screw 10. During the movement, the ball nut can drive the movable clamp 6 fixedly connected thereto to move. The coordinated use of the two movable clamps 6 can realize the support of the cup body or separation from the cup body. When the movable clamp 6 supports the cup body, the contraction of the electric telescopic rod 7 can make the movable clamp 6 drive the cup body to move upward, and the cup body above the movable clamp 6 and the cup below the movable clamp 6 can be separated.

[0031] The limiting structure includes a fixed block fixedly connected to the inner cavity of the storage cylinder, a double-headed ball screw 11 and a movable clamp 8 movably connected to the fixed block, the outer rings at both ends of the double-headed ball screw 11 are threadedly connected with ball nuts 2, the movable clamp 8 is fixedly connected to the ball nuts 2, a servo motor 13 is provided on one side of the fixed block, and the end of the output shaft of the servo motor 13 is connected to the double-headed ball screw 11. In some embodiments of the present application, the output shaft of the servo motor 13 is connected to the double-headed ball screw 11 through a synchronous structure 2, and the synchronous structure 2 includes a servo motor 13 connected to the end of the output shaft of the servo motor 13. The synchronous wheel 3 is fixedly connected to the end, the synchronous wheel 4 and the synchronous belt 2 are fixedly connected to the end of the double-headed ball screw 2 11, the synchronous wheel 3 and the synchronous wheel 4 are connected through the synchronous belt 2 transmission, and through the setting of the servo motor 2 13, the rotation of the servo motor 2 13 can drive the double-headed ball screw 2 11 to rotate, and the rotation of the double-headed ball screw 2 11 makes the ball nut 2 threadedly connected thereto move in the direction of the double-headed ball screw 2 11, and the ball nut 2 can drive the movable clamp 2 8 fixedly connected thereto to move during the movement, and the distance between the two movable clamps 28 can be changed.

[0032] When the device is in use, the working principle of the cup-taking structure is as follows: when the cup is placed in the storage tube, the two mobile clamps 28 support the cup. If the cup-taking operation is required, the servo motor 1 drives the double-ended ball screw 10 to rotate. The rotation of the double-ended ball screw 10 makes the two mobile clamps 16 approach each other until the mobile clamp 16 contacts the bottom of the cup edge of the cup adjacent to the mobile clamp 28. The servo motor 2 13 works. The work of the servo motor 2 13 makes the two mobile clamps 28 approach each other until the two mobile clamps 28 clamp the cup. The electric telescopic rod 17 contracts, and the electric telescopic rod 17 drives the mobile clamp 16 to move up. The mobile clamp 16 drives the cup in contact with it to move up. The cup clamped by the mobile clamp 28 is separated from the other cups. The servo motor 2 13 moves in the opposite direction. The work of the servo motor 2 13 makes the two mobile clamps 28 move away from each other until the mobile clamp 28 moves to the side of the cup. Under the action of gravity, the removed cup falls and falls on the top of the cup-taking structure. The servo motor 2 13 works until the operation of the servo motor 2 13 enables the two movable clamps 2 8 to support the cup, the electric telescopic rod 1 7 is reset, and the operation of the servo motor 1 separates the movable clamp 1 6 from the cup. Under the action of gravity, the cup at the bottom of the storage tube contacts the movable clamp 2 8.

[0033] The cup moving structure includes an electric telescopic rod 14 fixedly connected to the bottom of the inner cavity of the cup dropping tube 4, and the other end of the electric telescopic rod 14 is fixedly connected to a movable sealing plate 5. Under the action of the electric telescopic rod 14, the position of the movable sealing plate 5 can be changed. The movable sealing plate 5 is L-shaped, and the horizontal end of the movable sealing plate 5 contacts the bottom of the inner cavity of the cup dropping tube 4, and the vertical end of the movable sealing plate 5 is adapted to the open end of the cup dropping tube 4. The movable sealing plate 5 can be used to seal the open end of the cup dropping tube 4.

[0034] A ball screw 15 is movably connected to the top of the horizontal end of the movable sealing plate 5, and a ball nut three is threadedly connected to the outer ring of the ball screw 15. The ball nut three is fixedly connected to the lifting sleeve 16. The top of the lifting sleeve 16 is fixedly connected to a support plate 18, and a through hole adapted to the ball screw 15 is opened on the support plate 18. Through the setting of the ball screw 15, the rotation of the ball screw 15 can change the distance between the support plate 18 and the limiting structure, so that the device can adapt to cups of various heights, thereby improving the adaptability of the device.

[0035] The top of the support plate 18 and the outer surface of the movable clamp 28 are both wrapped with an isolation pad, and the isolation pad can be made of rubber.

[0036] A telescopic cover 17 is fixed to the top of the horizontal end of the movable sealing plate 5, and the top of the telescopic cover 17 is fixedly connected to the top of the support plate 18. The telescopic cover 17 can protect the ball screw 15 to prevent consumers from rotating the ball screw 15. The material of the telescopic cover 17 can be rubber. The side of the telescopic cover 17 away from the vertical end of the movable sealing plate 5 and the side of the telescopic cover 17 close to the fixed cylinder 1 are both provided with openings, so that the staff can easily rotate the ball screw 15.

[0037] A pressure sensor 12 is disposed on the top of the support plate 18. Through the arrangement of the pressure sensor 12, it can be determined whether a cup has fallen onto the support plate 18 or whether a cup on the support plate 18 has been taken away.

[0038] When the device is in use, both the movable clamp 1 6 and the movable clamp 2 8 are in contact with the bottom of the cup rim of the cup.

[0039] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0040] In summary: when the automatic coffee machine is used with the automatic cup dropping device, the inner cavity of the device is in a sealed state, the mobile clamp 2 supports the cup, and the ultraviolet disinfection lamp 3 is used to disinfect the cup. If the automatic coffee machine needs to take the cup, the servo motor 1 works, and the work of the servo motor 1 causes the double-headed ball screw 10 to rotate. The rotation of the double-headed ball screw 10 causes the two mobile clamps 1 6 to approach each other until the mobile clamp 1 6 contacts the bottom of the cup edge of the cup adjacent to the mobile clamp 2 8. The servo motor 2 13 works, and the work of the servo motor 2 13 causes the two mobile clamps 2 8 to approach each other until the two mobile clamps 2 8 clamp the cup inside thereof, and the electric telescopic rod 1 7 contracts. 7 drives the movable clamp 1 6 to move upward, and the movable clamp 1 6 drives the cup in contact with it to move upward, and the cup clamped by the movable clamp 2 8 can be separated from the other cups, and the servo motor 2 13 moves in the opposite direction. The operation of the servo motor 2 13 makes the two movable clamps 2 8 move away from each other until the movable clamp 2 8 moves to the side of the cup. Under the action of gravity, the cup separated from the movable clamp 1 6 falls, and the cup falls on the top of the support plate 18. When the pressure sensor 12 detects that the cup falls on the support plate 18, the electric telescopic rod 2 14 extends, and the electric telescopic rod 2 14 drives the movable sealing plate 5 to move outward until the cup moves to the outside of the cup drop tube 4, and the consumer can take the cup. After the cup is taken away, the cup taking structure is reset. During the operation of the cup-taking structure, the servo motor 2 13 works until the operation of the servo motor 2 13 enables the two movable clamps 2 8 to support the cup, the electric telescopic rod 1 7 is reset, and the operation of the servo motor 1 separates the movable clamp 1 6 from the cup. Under the action of gravity, the cup at the bottom of the storage tube contacts the movable clamp 2 8, and the movable clamp 2 8 supports the cup, so that the device can work again.
