[0033] Those skilled in the art can understand that, the fifth lead screw 803 is driven to rotate by the output end of the fifth stepper motor 805, so that the second lifting block 806 slides up and down along the surface of the fifth guide rod 804, thereby driving the mounting plate 810 to move up and down; by controlling the extension or contraction of the output end of the third electric push rod 807, the mounting plate 810 is driven to move left and right; the mounting plate 810 can be driven to rotate by the output end of the fourth drive motor 809; and the first gear 814 is driven to rotate by the output end of the transmission motor 819, and then the outer teeth 812, the rotating circle 811 and the inner teeth 813 rotate as a whole, so that all the second gears 815 rotate synchronously, driving all the tooth plates 817 to move synchronously toward or away from the center of the mounting plate 810, thereby driving all the arc-shaped clamping members 818 to move synchronously toward or away from the center of the mounting plate 810.

[0034] Working principle and use process of this device: In order to clearly describe the working principle of the present invention, we use Figure 1 From the perspective of the paint can filling process, there are two types of paint cans. One is that the top of the paint can is open. After the filling is completed, the top needs to be sealed. Fig.14 As shown, the first paint bucket 102 is a kind of, and the top of the other is encapsulated by itself. Fig.14 As shown, it is the second paint bucket 106; S1. If it is necessary to perform assembly line filling on the first paint bucket 102 on the external conveyor, the first threaded rod 204 is driven to rotate by the output end of the first servo motor 205, so that the two sets of first clamping plates 206 are close to each other, and the outer wall of the first paint bucket 102 is clamped. Under the action of the robot arm 101, the first paint bucket 102 is transferred to the workbench 302, and the center of the first paint bucket 102 and the center of the workbench 302 are located on the same vertical straight line; S2, the second threaded rod 303 is driven to rotate by the output end of the second servo motor 305, so that the two sets of second clamping plates 306 are close to each other, and the first paint bucket 102 is fixed on the top of the workbench 302 to prevent it from shifting; S3, the second screw rod 502 is driven to rotate by the output end of the second stepper motor 504, so that the first movable member 601 slides along the second guide rod 503 and moves to the middle of the right side of the machine body 1, and then the third screw rod 603 is driven to rotate by the output end of the third stepper motor 605, so that the movable plate 606 moves to the left side, so that the discharge pipe 607 moves to the top of the first paint bucket 102, and the first paint bucket 102 is filled by opening the valve 608 and starting the external water pump; S4. After the filling is completed, the output end of the third driving motor 703 drives the driving wheel 704 to rotate clockwise, drives the rotating cylinder 702 to rotate clockwise, and under the action of the output end of the fourth stepping motor 709, drives the suction cup 713 to move downward, and absorbs and grabs the cover plate 104 in a stacked state outside. Then, under the action of the output end of the third driving motor 703, the rotating cylinder 702 rotates counterclockwise to reset. Then, under the action of the output end of the second stepping motor 504, the second movable member 701 moves along the The second stepper motor 709 slides on the second guide rod 503 and moves to the middle of the right side of the machine body 1, and then extends through the output end of the second electric push rod 711, driving the suction cup 713 to move to the left and move to the top of the first paint bucket 102. At this time, the center of the cover plate 104 and the center of the first paint bucket 102 are also located on the same vertical line. Under the action of the output end of the fourth stepper motor 709, the suction cup 713 and the cover plate 104 move downward as a whole, and the suction cup 713 is released from adsorption, and the cover plate 104 is placed on the top of the first paint bucket 102. S5. Under the action of the output end of the second stepper motor 504, the third movable member 801 slides along the second guide rod 503 and moves to the middle of the right side of the machine body 1. By controlling the extension of the output end of the third electric push rod 807, the mounting plate 810 moves to the left. At this time, the center of the mounting plate 810 and the center of the first paint bucket 102 are also located on the same vertical straight line. The output end of the fifth stepper motor 805 drives the fifth screw rod 803 to rotate, so that the mounting plate 810 moves downward. The top of the first paint bucket 102 is located inside the mounting plate 810. The output end of the transmission motor 819 drives the first gear 814 to rotate, thereby driving all the arc-shaped pressing members. 818 synchronously moves toward the position close to the center of the mounting plate 810, pressing the ear plate 105 on the cover plate 104 into the notch 103. It should be noted here that since the position of the arc-shaped pressing member 818 does not necessarily correspond to the position of the ear plate 105, a fourth drive motor 809 is adapted to be provided, and the mounting plate 810 is driven to rotate by the output end of the fourth drive motor 809, so that the position of the arc-shaped pressing member 818 corresponds to the position of the ear plate 105. After the pressing is completed, the entire filling process of the first paint bucket 102 is realized, and the robot arm 101 and the first clamping mechanism 2 cooperate to transfer it to another external conveyor for transportation, and the whole process is automated; S6. Another method is to fix the second paint bucket 106 on the external conveyor to the workbench 302 by cooperating with the robot arm 101, the first clamping mechanism 2 and the second clamping mechanism 3. S7, the output end of the first drive motor 301 drives the workbench 302 to rotate, thereby driving the second paint bucket 106 in the clamping state to rotate, so that the center of the cover 107 on the second paint bucket 106 and the center of the frame 409 are located on the same vertical plane, and then the output end of the first stepper motor 404 drives the first screw rod 402 to rotate, and then the frame 409 and the two groups of third clamping plates 413 move downward as a whole, so that the cover 107 is located between the two groups of third clamping plates 413, and the output end of the third servo motor 412 drives the third threaded rod 410 to rotate, so that the two groups of third clamping plates 413 are close to each other to clamp the cover 107, and the output end of the first stepper motor 404 rotates in the opposite direction, driving the frame 409 and the two groups of third clamping plates 413 to move upward as a whole, and at the same time, the output end of the second drive motor 408 rotates to achieve the twisting off of the cover 107; S8. Under the action of the output end of the second stepper motor 504, the first movable member 601 moves to the middle of the right side of the machine body 1, and the output end of the first drive motor 301 drives the workbench 302 to rotate again, so that the center position of the cover 107 and the center of the first movable member 601 are located on the same vertical plane, and the output end of the third stepper motor 605 drives the third screw rod 603 to rotate, so that the movable plate 606 moves to the left, so that the discharge pipe 607 moves to the top of the second paint bucket 106, and the second paint bucket 106 is filled by opening the valve 608 and starting the external water pump; S9. After the filling of the second paint bucket 106 is completed, the cover 107 is twisted on the feeding end of the second paint bucket 106 under the action of the capping mechanism 4 to complete the entire filling process of the second paint bucket 106. The robot arm 101 and the first clamping mechanism 2 cooperate to transfer it to another external conveyor for transportation, and the whole process is automated.
