[0042] The following will combine the accompanying drawings to make a detailed description of the specific embodiments of the opening and closing cover device of the present invention with a screw-threaded container.

[0043] Refer to the attached Figure 1 , the opening and closing cover device of the screw-threaded container includes a container platform 1 and an opening and closing cover mechanism 2. The container platform 1 is used to arrange the screw-threaded container 3. The opening and closing cover mechanism 2 is used to perform the operations of opening and closing the cover of the container 3.

[0044] Refer to the attached Figure 2 , 3 , the opening and closing cover mechanism 2 includes an L-shaped support 4. A rotating chuck 7 is arranged on the support 4 through a vertical lifting unit 5 and a horizontal moving unit 6. The vertical lifting unit 5 includes a vertical guide rail seat 8. The vertical guide rail seat 8 is arranged on the support 4 through a slide rail. A vertical driving component is arranged on the vertical guide rail seat 8, and the vertical driving component drives the vertical guide rail seat 8 to vertically lift on the support 4.

[0045] The horizontal moving unit 6 is arranged on the vertical guide rail seat 8. The horizontal moving unit 6 includes a horizontal guide rail seat 9. The horizontal guide rail seat 9 is arranged above the vertical guide rail seat 8 through a slide rail. A horizontal driving component is arranged on the horizontal guide rail seat 9, and the horizontal driving component drives the horizontal guide rail seat 9 to horizontally move on the vertical guide rail seat 8.

[0046] Both the vertical driving component and the horizontal driving component are cylinders, which are respectively a vertical cylinder 10 and a horizontal cylinder 11. The piston head of the vertical cylinder 10 cooperates with the support 4 to drive the vertical guide rail seat 8 to lift, and the piston of the horizontal cylinder 11 cooperates with the vertical guide rail seat 8 to drive the horizontal guide rail seat 9 to move. The vertical cylinder 10 is installed on the vertical guide rail seat 8, and the piston head of the vertical cylinder 10 is connected to the bottom of the support 4. When the vertical cylinder 10 works, the vertical guide rail seat 8 is pushed up and down through the piston head. The horizontal cylinder 11 is installed on the horizontal guide rail seat 9, and the piston head is installed on the vertical guide rail seat 8, and in the same way, the horizontal guide rail seat 9 is driven to horizontally move relative to the vertical guide rail seat 8.

[0047] The rotating chuck 7 is arranged at the front end of the horizontal guide rail seat 9. The rotating chuck 7 includes a rotating component and a clamping component. The clamping component is arranged below the rotating component. The rotating component is driven by a motor arranged on the horizontal guide rail seat 9, and the motor transmits the rotation to the rotating component through a belt. The clamping component is a pneumatic claw 12, and the rotating component is a pneumatic rotary joint 13. The pneumatic claw 12 is connected to the pneumatic rotary joint 13. The pneumatic rotary joint 13 realizes the supply of air to the pneumatic claw 12 while rotating, and does not affect the air supply of the pneumatic claw 12 during rotation.

[0048] To prevent the pneumatic rotary joint 13 from affecting the air gripper 12 during rotation, a stop bracket 14 is provided between the rotating component and the horizontal guide rail base 9.

[0049] Continue to refer to the appendix Figure 1 , The container platform 1 is arranged below the lid opening and closing mechanism 2. A container 3 with a screw thread is arranged on the container platform 1. The vertical lifting unit 5 and the horizontal moving unit 6 move the rotating chuck 7 above the container 3. The vertical lifting unit 5 drives the rotating chuck 7 to descend to the lid opening and closing position of the container 3. The rotating chuck 7 holds the container lid 24 and then screws it out of the container 3 or screws the held container lid 24 into the container 3.

[0050] Refer to the appendix Figure 4 , 5 , A container clamp 15 is arranged on the container platform 1. The container clamp 15 is two symmetrically arranged fitting clips 16. The rear ends of the two clips 16 are rotatably arranged on the container platform 1 through a rotating shaft. The front ends of the two clips 16 are wedge-shaped angles. A container accommodating hole 17 is formed between the two clips 16. A wedge groove block 19 is arranged on the support 4 through a bottom cylinder 18. After the bottom cylinder 18 extends the wedge groove block 19, it cooperates with the wedge-shaped angles of the two clips 16 to limit the container clamp 15 and fix the container 3 in the container accommodating hole 17. The container clamp 15 and the horizontal guide rail base 9 are on the same vertical plane.

[0051] A cap rack 23 is arranged on the rotating shaft. The size of the cap rack is smaller than the size of the screw thread of the container 3, and the height is not higher than the position of the screw thread of the container 3. The cap rack 23 is used to place the container lid 24. Small holes are arranged on the side wall of the container accommodating hole 17, and rubber columns 20 protrude from the holes. Limit screws 21 are arranged at positions near the front ends of the two clips 16, and thrust springs 22 are sleeved on the limit screws 21 to limit the opening size of the container clamp 15.

[0052] Continue to refer to the appendix Figure 1 , The container platform 1 is circular and is arranged on the base through a turntable. A plurality of container clamps 15 are arranged on the container platform 1. The container clamps 15 are arranged in a star shape on the container platform 1. The plurality of container clamps 15 are located at multiple workstations of the lid opening and closing device. There are two lid opening and closing mechanisms 2, which are arranged on both sides outside the container platform 1. When the turntable rotates by the angle of one workstation, the first opening and closing mechanism performs the lid opening operation on the container 3 on the container clamp 15, and the second opening and closing mechanism performs the lid closing operation on the container 3 on the container clamp 15.

[0053] When applied to the pretreatment project of pesticide residues, first, the manipulator places the container 3 filled with sample powder into the container clamp 15 on the container table 1. The container table 1 rotates one station to the position below the first lid-opening and closing mechanism 2. The first lid-opening and closing mechanism 2 drives the bottom cylinder 18 to move towards the container clamp 15. The wedge groove block 19 cooperates with and fixes the two clamping pieces 16 of the container clamp 15 to position the container 3 on the container clamp 15. The lid-opening and closing mechanism 2 drives the rotating chuck 7 to descend from above the container 3. The air claw 12 clamps the container lid 24. The rotating chuck 7 rotates to unscrew the container lid 24. Then, the horizontal guide rail base 9 rises and moves forward, so that the air claw 12 is located above the cap rack on the container clamp 15. After descending a certain distance, the container lid 24 is placed on the cap rack, and the lid-opening and closing mechanism 2 resets.

[0054] Then, the container table 1 rotates one station, and the equipment performs operations such as liquid injection on the container 3 from which the container lid 24 has been removed. According to the actual process steps, after completing one or more operations, it rotates to the second lid-opening and closing mechanism 2. After the second lid-opening and closing mechanism 2 removes the container lid 24 from the cap rack, it is sent to the container 3 for the rotating lid-closing action to complete the sealing of the container 3. The specific process is similar to the lid-opening process. After the lid-closing of the container 3 is completed, it rotates to the subsequent station and is sent to the subsequent process operation by the manipulator.

[0055] During the working process, the working process can be monitored through multiple sensors to cooperate with the control of the normal operation of each component during work. For example, by adding a photoelectric sensor 25 (see the appendix Figure 2 、 3 ), it is monitored whether the air claw 12 can normally grasp the container lid 24.

[0056] The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
