Description

Technical Field

[0001] This utility model relates to the field of material transfer equipment technology, and in particular to a permanent magnet chuck for transferring beverage can bodies. Background Technology

[0002] In the production of aluminum cans, can transfer is one of the key processes, requiring the transfer of finished cans from one production line to another, or for operations such as stacking and packing. Currently, the most common transfer method in the industry is mechanical grippers.

[0003] Mechanical grippers achieve transfer by clamping the sides of the can with grippers, but this method has obvious drawbacks: on the one hand, the clamping force of the grippers is difficult to control precisely; excessive clamping force will cause the can to deform, while insufficient clamping force will cause the can to fall off; on the other hand, the fixed structure of mechanical grippers makes it inconvenient to grip covers of different widths, reducing the ease of use of the device. Therefore, to address the above problems, a permanent magnet chuck for transferring easy-open cans is proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A permanent magnet chuck for transferring aluminum cans includes a robot connecting column. The bottom of the robot connecting column passes through a second connecting seat and is fixedly connected to the top of a first connecting seat. The front and rear ends of the first connecting seat are respectively connected to the bottom of the second connecting seat and the top side of the permanent magnet disk through a flexible connecting mechanism. The top of the second connecting seat is fixedly connected to the bottom of the middle of the top frame. The front and rear ends of the top frame are provided with cover plate gripping mechanisms. The left and right ends of the top frame are provided with solenoid valve groups. The left and right ends of the top frame are equipped with disk lifting cylinders.

[0019] Please see Figure 1-4 This utility model provides an embodiment of a permanent magnet chuck for transferring can bodies, including a robot connecting column 1. The bottom of the robot connecting column 1 passes through a second connecting seat 23 and is fixedly connected to the top of a first connecting seat 11. The front and rear ends of the first connecting seat 11 are respectively connected to the bottom of the second connecting seat 23 and the top side of the permanent magnet disk 4 through a soft connecting mechanism. The top of the second connecting seat 23 is fixedly connected to the bottom of the middle of the top frame 2. The front and rear ends of the top frame 2 are provided with cover plate gripping mechanisms. The left and right ends of the top frame 2 are provided with electromagnetic valve groups 43. The left and right ends of the top frame 2 are equipped with disk lifting cylinders 22. The telescopic ends of the disk lifting cylinders 22 are fixedly connected to the top of the two ends of the permanent magnet disk 4. The bottom of the front and rear ends of the top frame 2 is fixedly connected to the top of a connecting rod 21. The bottom of the connecting rod 21 passes through the through hole of the permanent magnet disk 4 and is connected to the top side of the disk mounting plate 5. The disk mounting plate 5 is located below the permanent magnet disk 4.

[0020] The permanent magnet disk 4 has suction cup mounting plates 41 installed at the top of both ends. Suction cup connecting tubes 42 are installed inside both ends of the suction cup mounting plates 41. Suction cups are installed at the bottom of the suction cup connecting tubes 42. The suction cups are located in the through holes inside the disk mounting plate 5. The suction cup connecting tubes 42 are connected to external pneumatic components, and the suction force of the suction cups is controlled by the external pneumatic components.

[0021] The flexible connection mechanism includes multiple second connecting rods 61. One end of each second connecting rod 61 is connected to the bottom of the four corners of the second connecting seat 23, and the other end is fixed to the top side of the permanent magnet disk 4. A linear motion ball bearing 62 is installed in the middle of the second connecting rod 61. The linear motion ball bearing 62 is installed inside the mounting holes at the four corners of the first connecting seat 11. A spring 63 is provided on the outside of the second connecting rod 61 at the distance between the second connecting seat 23 and the first connecting seat 11. The second connecting rod 61 slides along the linear motion ball bearing 62 at the four corners of the first connecting seat 11. The spring 63 located on the outside of the second connecting rod at the distance between the second connecting seat 23 and the first connecting seat 11 can buffer the impact force when the disk descends, and prevent the canister from being damaged due to hard contact.

[0022] The cover plate gripping mechanism includes a cover plate gripping connecting shaft 31 installed inside the front and rear ends of the top frame 2. A flange-type oil-free bushing is provided at the connection between the cover plate gripping connecting shaft 31 and the top frame 2. Swing blocks 32 are provided on the outer sides of both ends of the cover plate gripping connecting shaft 31. The telescopic end of the hydraulic rod 33 is hinged to the swing block 32, and the other end of the hydraulic rod 33 is hinged to the side of the top frame 2. Connecting blocks 34 are provided at both ends of the cover plate gripping connecting shaft 31. A gripping hydraulic rod 35 is installed on the side of the connecting block 34, and a clamping block 36 is installed on the telescopic end of the gripping hydraulic rod 35.

[0023] The clamping block 36 has a triangular-shaped locking block on the contact surface with the partition. When the clamping block 36 clamps the two sides of the cover plate, the triangular locking block of the clamping block 36 presses against the bottom side of the cover plate to prevent the cover plate from falling off during movement.

[0024] The connecting block 34 is provided with multiple mounting holes, which are evenly distributed inside the connecting block 34. Depending on the width of the cover plate being gripped, the connecting block 34 can be disassembled and reinstalled using the multiple mounting holes evenly distributed on the connecting block 34, and the lateral spacing of the connecting block 34 can be adjusted to adapt to cover plates of different specifications.

[0025] The actuator of the external transfer robot is fixed to the top of the robot connecting column 1, completing the power and positioning connection between the equipment and the robot, enabling the robot to drive the entire permanent magnet chuck to move in three-dimensional space.

[0026] Check the connection status of the solenoid valve group 43 inside the left and right ends of the top frame 2 with the external air source and control unit to ensure that the disk lifting cylinder 22, the hydraulic rod 33 in the cover plate gripping mechanism and the gripping hydraulic rod 35 can receive control signals normally. At the same time, confirm that the magnetic control switch of the permanent magnet disk 4 is in the closed state to avoid accidental adsorption of the tank in the initial stage.

[0027] The robot moves the top frame 2 above the partition of the can storage rack, aligning the connecting blocks 34 at both ends of the cover gripping connecting shaft 31 with the sides of the partition. At this time, the flange-type oil-free bushing at the connection between the cover gripping connecting shaft 31 and the top frame 2 reduces the rotational friction of the shaft, ensuring alignment accuracy.

[0028] The hydraulic system is activated, causing the extension end of the hydraulic rod 33 to extend, pushing the swing block 32 to rotate around the cover plate gripping connecting shaft 31, which in turn drives the connecting block 34 to move closer to the cover plate. After the side of the clamping block 36 is parallel to the side of the cover plate, the extension end of the gripping hydraulic rod 35 extends, and the clamping block 36 clamps the two sides of the cover plate. At the same time, the triangular locking block of the clamping block 36 presses against the bottom side of the cover plate to prevent the cover plate from falling off during movement. The cover plate gripping mechanism is used to grip the top cover plate after the tank is placed.

[0029] The robot moves the entire device above the partition according to preset coordinates, and uses the permanent magnet disk 4 to hold the partition. It then moves the partition directly above the can to be grasped, placing it on the top side of the can. Simultaneously, the telescopic end of the disk lifting cylinder 22 lowers the permanent magnet disk 4. The suction cup connecting tube 42 on the suction cup mounting plate 41 and the suction cup descend, holding the partition in place and increasing stability during movement. The permanent magnet disk 4 descends into the disk mounting plate 5. The closer the permanent magnet suction cup is to the partition, the stronger the suction force. The partition is made of stainless steel. Its main functions are twofold: first, to separate each layer of cans during stacking, facilitating neat arrangement. Secondly, during the gripping process of the permanent magnet chuck, it acts as an intermediate medium to prevent the permanent magnet chuck from directly contacting the can body, thereby preventing scratches on the can body. The partition can also make the magnetic force distribution more uniform and improve the gripping stability. After the cans are stacked, the chuck is released, and the disk lifting cylinder 22 drives the permanent magnet disk 4 to rise. At this time, the disk mounting plate 5 still presses against the surface of the partition, allowing the permanent magnet disk 4 to separate from the partition. The robot then moves the entire device to the top of the next partition and repeats the above operation.
