Description

Technical Field

[0001] This utility model relates to the field of metal can lid production and processing technology, and in particular to a robotic arm used in a metal can lid film wrapping machine. Background Technology

[0002] Metal can lid wrapping machines, as modern packaging equipment, are widely used in the sealing process of metal cans. They ensure precise sealing of the lid and film, improving the product's airtightness and protection. With the advancement of industrialization, the requirements for packaging equipment are constantly increasing, especially in terms of speed, precision, and automation. The application of robotic arms in metal can lid wrapping machines has become key to improving production efficiency. Robotic arms can accurately grasp and place the film, automatically transfer and position the lid, and perform the bonding process between the film and lid, significantly reducing errors and labor intensity caused by manual operation. Their design and optimization must consider not only load capacity, precision requirements, and the working environment, but also ensure coordination with other automated equipment. With the continuous development of artificial intelligence, sensor technology, and new materials, the application of robotic arms in metal can lid wrapping machines will become more intelligent, driving the automation and intelligent upgrading of the packaging industry and further improving the flexibility, efficiency, and safety of production lines.

[0003] However, in practical applications of existing solutions, most involve clamping metal caps from both sides using gripping arms. Multiple caps are secured by the friction of the caps themselves and the pressure applied by the gripping arms. While this improves gripping efficiency, it also presents several potential problems. First, excessive pressure or uneven friction can cause scratches or indentations on the metal cap surface, affecting its appearance. Second, this gripping method may not provide stable fixation, especially at high speeds, potentially causing the caps to slip or loosen, increasing production instability. The continuous action of friction and pressure can also lead to wear on the gripping arms or the surface of the caps, reducing gripping effectiveness and increasing maintenance costs. Finally, this gripping method requires precise design and control systems; any improper operation can lead to instability in the robot's performance, increasing the complexity of debugging and maintenance.

[0004] Therefore, this utility model provides a robotic arm for a metal can lid film wrapping machine. Utility Model Content

[0020] Compared with the prior art, this utility model provides a robotic arm for a metal can lid wrapping machine, which has the following advantages:

[0021] 1. The robotic arm for a metal can lid film wrapping machine described in this utility model uses pneumatic rods on both sides to drive a transmission rod, a connecting rod, and a clamping head to move in opposite directions simultaneously, thereby clamping the metal can lid. During the process, the transmission rods drive the extrusion blocks to move in opposite directions simultaneously, thereby squeezing the second sliders on both sides, forcing the second sliders and support heads to move outward, thus pushing the top of the clamping arm outward. This causes the clamping arm to rotate around the hinge frame as the stress point, thereby driving the clamping plate to clamp the metal can lid from the side, preventing the lid from shifting or rotating, improving production efficiency and reducing downtime. At the same time, bidirectional clamping can apply force evenly, reducing the risk of lid damage.

[0022] 2. The robotic arm for a metal can lid wrapping machine described in this utility model uses a second motor to drive a worm gear and a turntable simultaneously, thereby rotating the bottom support rod through the turntable. This allows for adjustment of the angle of the metal can lid, improving the robotic arm's flexibility and space utilization. It enables the robotic arm to flexibly adjust its position within a limited space to adapt to different operational needs. This method also allows for precise control of the robotic arm's movement trajectory, ensuring accurate positioning of the metal can lid, reducing deviations, minimizing manual intervention, and improving work efficiency and safety.

A clamping head 34 is fixedly connected to the bottom side of the connecting rods 33 that are close to each other. The transmission rod 32 drives the clamping head 34 to move synchronously through the connecting rod 33, thereby clamping and fixing the metal cover 35.

[0049] The auxiliary clamping assembly includes a base plate 4 fixed to both sides of the top of the support rod 3. The support rod 3 supports and fixes the base plate 4. A sliding groove 41 is provided on the top of the base plate 4. A pressing block 42 is slidably connected to the side of the sliding groove 41 away from each other. The pressing block 42 is limited by the sliding groove 41. The pressing block 42 is fixedly connected to the side of the transmission rod 32 away from the connecting rod 33. The transmission rod 32 fixes the pressing block 42. When the air rod 31 drives the transmission rod 32 to move the connecting rod 33 and the clamping head 34 to clamp the metal cover 35, the pressing block 42 moves synchronously through the transmission rod 32. The middle section of the base plate 4 is slidably connected perpendicularly to the sliding direction of the pressing block 42. The second slider 43 is squeezed by the movement of the pressing block 42, forcing the second slider 43 to move to both sides simultaneously.

[0050] Two sets of limiting plates 5 are symmetrically fixedly connected to the top of the base plate 4 on the side away from the extrusion block 42. The limiting plates 5 are supported and fixed by the base plate 4. A sliding rod 54 is fixedly connected to the inner side of the limiting plate 5. The sliding rod 54 is supported and fixed by the limiting plate 5. A sliding frame 51 is slidably connected to the sliding rod 54. The sliding frame 51 is limited by the sliding rod 54, so that the sliding frame 51 slides on the outside of the sliding rod 54. A through hole 53 is opened on the side of the sliding frame 51 away from each other. The through hole 53 is slidably connected to the sliding rod 54. The longitudinal diameter of the through hole 53 is larger than the diameter of the sliding rod 54, so that the sliding rod 54 can slide. The sliding frame 51 moves up and down within the through hole 53. One end of the sliding frame 51 is engaged with a set of limiting plates 5. The sliding frame 51 and the limiting plates 5 are arranged crosswise. A spring 52 is fixedly connected to the inner wall of the sliding frame 51. The other end of the spring 52 is fixedly connected to the inner wall of the limiting plates 5 which are far apart. The spring 52 pushes the sliding frame 51 inward with the limiting plate 5 at the outer end as the stress point. A limiting rod 55 is fixedly connected to the outer wall of the sliding frame 51. The sliding frame 51 drives the limiting rod 55 to move synchronously. Thus, the top of the clamping arm 46 can be moved inward through the limiting rod 55.

[0051] Specifically, the robotic arm originally intended for use in metal can lid wrapping machines is used as follows:

[0052] First: The first motor 11 drives the helical gear 12 to rotate, and the helical gear 12 drives the rack 15 to rise and fall. At the same time, the rack 15 drives the lifting rod 14 and the slide rail 16 to rise and fall inside the support frame 1 and the first slider 13. Simultaneously, the lifting rod 14 drives the bottom structure to rise and fall.

[0053] The second motor 21 drives the worm gear 22 to rotate with the rotating box 2 as the stress point. At the same time, the worm gear 22 drives the worm wheel 23 to rotate, which in turn drives the turntable 24 to rotate, and the turntable 24 drives the support rod 3 to rotate.

[0054] The transmission rod 32 is driven by the pneumatic rod 31 to move laterally, and the clamping head 34 is driven by the connecting rod 33 through the transmission rod 32 to move in the opposite direction, thereby clamping and fixing the metal cover 35 through the clamping head 34.

[0055] Simultaneously, the transmission rod 32 drives the extrusion block 42 to move synchronously when moving in opposite directions. During the process, the extrusion block 42 extrudes the second slider 43, causing the second slider 43 to move outward and drive the support head 44 to move synchronously. The support head 44 supports the top of the clamping arm 46, causing the top of the clamping arm 46 to move outward at the same time. Meanwhile, the clamping arm 46 rotates with the hinge frame 45 as the stress point, causing the bottom of the clamping plate 47 to move inward, thereby clamping and fixing the outer side of the metal cover 35.

[0056] During the clamping process, when the top of the clamping arm 46 rotates outward, the limiting rod 55 drives the sliding frame 51 to move outward simultaneously, compressing the spring 52. When the clamping of the metal cover 35 is released, the spring 52 pushes the sliding frame 51 inward with the limiting plate 5 as the stress point, and the sliding frame 51 drives the limiting rod 55 to move inward simultaneously. Then, the limiting rod 55 drives the top of the clamping arm 46 to move inward simultaneously, resetting the clamping arm 46.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
