Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, specifically to an automatic module mechanism for tightening bottle caps. Background Technology

[0002] As a key component of sealed containers, bottle caps not only ensure the airtightness of the contents but also provide anti-theft and security functions. They are an indispensable part of the upstream industries in the food, beverage, wine, chemical, and pharmaceutical sectors, and are crucial for the packaging of bottled containers. Bottle caps and containers need to be tightened to function effectively. Since packaging bottles are generally sold in large quantities, a bottle cap tightening structure is required to tighten the bottle cap to the container.

[0003] Most current bottle cap tightening technologies on the market use a combination of linear modules and pneumatic grippers to tighten bottle caps, which takes up a lot of space. In some production environments with limited space, installation and layout are restricted. In addition, pneumatic grippers rely on an air source for operation, which requires additional air source equipment such as air compressors and air tanks, as well as the laying of complex air pipelines, increasing equipment costs and installation difficulty. Therefore, an automatic module mechanism for bottle cap tightening is proposed to solve the problems mentioned above. Utility Model Content

In some production environments with limited space, the installation and layout are restricted. In addition, the pneumatic grippers rely on an air source for drive, which requires additional air source equipment such as air compressors and air tanks, as well as the laying of complex air pipelines, increasing equipment costs and installation difficulty.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figures 1-5 As shown, an automatic module mechanism for tightening bottle caps includes a flange connecting plate 1. A first mounting base 2 is fixedly connected to the lower end of the flange connecting plate 1. A protective shell 3 is fixedly connected to the lower end of the first mounting base 2.

A lifting seat 6 is threaded onto the outer surface of the first lead screw 5. Connecting posts 7 are fixedly connected to the four corners of the lower end of the lifting seat 6. A second mounting base 8 is fixedly connected to the lower end of the connecting posts 7. A second servo motor 9 is fixedly mounted inside the second mounting base 8. A first coupling 10 is fixedly connected to the output end of the second servo motor 9. A drive shaft 11 is fixedly connected to the other end of the first coupling 10. A first connecting plate 12 is fixedly connected to the lower end of the drive shaft 11. A third... Mounting base 13, a third servo motor 14 is fixedly mounted on the inner side of the third mounting base 13, a gripper flange 15 is fixedly connected to the lower end of the third mounting base 13, a gripper fixing seat 18 is fixedly connected to the lower end of the gripper flange 15, a sliding groove 19 is opened at the upper end of the gripper fixing seat 18, a central column 20 and three evenly distributed first mounting plates 21 are slidably connected inside the sliding groove 19, the first mounting plates 21 are fixedly connected to the outer surface of the central column 20, three evenly distributed second mounting plates 22 are fixedly connected to the lower end of the gripper fixing seat 18, a set of first swing rods 23 are rotatably connected to the outer surface of each of the three first mounting plates 21, a set of second swing rods 24 and a set of third swing rods 25 are rotatably connected to the outer surface of each of the three second mounting plates 22, and a clamping block 26 is rotatably connected to the inner side of each set of first swing rods 23, second swing rods 24 and third swing rods 25.

[0022] Furthermore, the lower end of the flange connecting plate 1 is welded and fixed to the first mounting base 2, and the upper end can be connected to the end flange of the industrial robot or the fixed station bracket by bolts.

[0023] Furthermore, by rotating the first lead screw 5 driven by the first servo motor 4, the lifting seat 6 can move up and down along the surface of the first lead screw 5, thereby causing the components at the bottom of the lifting seat 6 to move up and down as a whole, thus adjusting the height position of the clamping block 26.

[0024] Furthermore, the output end of the third servo motor 14 is fixedly connected to the second coupling 16, which is fixedly connected to the inner side of the gripper flange 15. The other end of the second coupling 16 is fixedly connected to the second lead screw 17, and the center column 20 is threadedly connected to the outer surface of the second lead screw 17.

[0025] Furthermore, a second connecting plate 27 is fixedly connected to the rear end of the second mounting base 8, and a support rod 36, a fifth mounting base 30, and a fourth mounting base 28 are fixedly connected to the front end of the second connecting plate 27. An electric slip ring 32 is fixedly connected to the front end of the support rod 36, and the inner wall of the inner ring of the electric slip ring 32 is fixedly connected to the outer surface of the drive shaft 11. A second bearing 31 is fixedly connected to the inner side of the fifth mounting base 30, and the inner wall of the inner ring of the second bearing 31 is fixedly connected to the outer surface of the clamp flange 15. A first bearing 29 is fixedly connected to the inner side of the fourth mounting base 28, and the inner wall of the inner ring of the first bearing 29 is fixedly connected to the outer surface of the drive shaft 11.

[0026] Furthermore, the second servo motor 9 drives the drive shaft 11 to rotate, which in turn drives the lower clamping block 26 to rotate, thus achieving the tightening action of the bottle cap.

[0027] Furthermore, the electric slip ring 32 is used to realize the electrical connection of the drive shaft 11 when it rotates, the second bearing 31 is used to support the rotation of the gripper flange 15, and the first bearing 29 is used to support the rotation of the drive shaft 11.

[0028] Furthermore, when the third servo motor 14 is working, it drives the second lead screw 17 to rotate through the second coupling 16. Since the central column 20 is threadedly connected to the second lead screw 17, it will move up and down in the slide groove 19, thereby driving the first mounting plate 21 to move. The first mounting plate 21 drives the clamping block 26 to move through the first swing arm 23, thereby realizing the clamping and releasing of the clamping block 26.

[0029] Furthermore, when the first mounting plate 21 moves upward, the three clamping blocks 26 expand outward to release the bottle cap; when the first mounting plate 21 moves downward, the three clamping blocks 26 retract inward to clamp the bottle cap.

[0030] Furthermore, the protective shell 3 has two symmetrically distributed slide rails 33 fixedly connected inside. The left and right ends of the second mounting base 8 and the fourth mounting base 28 are fixedly connected to limit strips 34. The two limit strips 34 are slidably connected to the inner side of the two slide rails 33 respectively. The cooperation between the slide rails 33 and the limit strips 34 can restrict the movement direction of the second mounting base 8 and the fourth mounting base 28, ensuring the smoothness of the lifting movement.

[0031] Furthermore, an end protective shell 35 is fixedly connected to the lower end of the protective shell 3 to protect the internal structure.

[0032] Working principle: In use, the flange connecting plate 1 is connected to the robot end flange or fixed station with bolts. When it is necessary to tighten the bottle cap, the first servo motor 4 starts, driving the first lead screw 5 to rotate. The lifting seat 6 moves downward along the first lead screw 5, bringing the clamping block 26 close to the bottle cap. Then, the third servo motor 14 works, driving the central column 20 downward through the second lead screw 17. The first mounting plate 21 moves accordingly, and the first swing arm 23 drives the clamping block 26 to clamp the bottle cap. Then, the second servo motor 9 starts, through the first coupling 10... The drive shaft 11 drives the clamping block 26 to rotate, thus tightening the bottle cap. After tightening, the third servo motor 14 rotates in the opposite direction, causing the clamping block 26 to loosen. The first servo motor 4 drives the lifting seat 6 to rise and return to the initial position. During the entire operation, the electric slip ring 32 ensures the electrical connection when the drive shaft 11 rotates. The first bearing 29 and the second bearing 31 support the rotation of the drive shaft 11 and the clamping flange 15, respectively. The slide rail 33 and the limit bar 34 ensure the smoothness of the lifting movement. The end protective shell 35 protects the internal structure.
