The isolation cover 21 is detachably connected to the connecting frame 14. The plurality of magnetic groups 23 are arranged side by side in the isolation cover 21. An isolation plate 22 is slidably connected below the plurality of magnetic groups 23 in the isolation cover 21. A switch assembly and a lifting assembly are provided on the isolation cover 21. The switch assembly is used to control the synchronous opening and closing of the magnetic force of the plurality of magnetic groups 23. The lifting assembly is used to change the gap between the isolation plate 22 and the plurality of magnetic groups 23 so as to adjust the magnetic force of the magnet 20.

[0019] Each magnetic force group 23 includes a magnetic bar 231, a yoke 232 and a non-magnetic block 233. The left and right sides of the magnetic bar 231 are respectively provided with two yokes 232. The two ends of the yokes 232 are respectively fixed to the front and rear side walls inside the isolation cover 21. The upper and lower sides of the magnetic bar 231 are respectively provided with two non-magnetic blocks 233. The two non-magnetic blocks 233 are clamped by the two yokes 232. The magnetic bar 231 can rotate between the two yokes 232 and the two non-magnetic blocks 233. The magnetic bar 231 has an N pole and an S pole along the diameter direction.

[0020] The switch assembly includes a U-shaped rod 30 and an electric push rod 31. The two protruding ends of the U-shaped rod 30 are respectively slidably connected to the front and rear sides of the isolation cover 21. The electric push rod 31 is installed on the top of the isolation cover 21. The telescopic rod of the electric push rod 31 is fixedly connected to the middle of the U-shaped rod 30. The front and rear ends of the magnetic rod 231 are rotated to pass through the isolation cover 21 and are fixedly connected to a gear 32. The bottom of the two protruding ends of the U-shaped rod 30 is fixedly connected to a rack 33 matching the gear 32. When the electric push rod 31 is extended and retracted, the meshing action of the rack 33 and the gear 32 drives the magnetic rod 231 to rotate between the two yokes 232 and the two non-magnetic blocks 233 to realize the opening and closing of the magnetic force.

[0021] The lifting assembly includes a hydraulic cylinder 40, a connecting rod 41 and a fixed rod 42. The four corners of the isolation plate 22 are fixedly connected with fixed rods 42. The fixed rods 42 slide through the top of the isolation cover 21. The two fixed rods 42 on the front and rear sides of the isolation cover 21 are respectively fixed to a connecting rod 41. Hydraulic cylinders 40 are installed on both the front and rear sides of the top of the isolation cover 21. The telescopic rod of each hydraulic cylinder 40 is connected to the connecting rod 41 on the same side. Through the telescopic movement of the hydraulic cylinder 40, the connecting rod 41 and the fixed rod 42 are pushed or pulled, thereby driving the isolation plate 22 to move up and down.

[0022] A linear drive component 50 is installed on the top rear side of the frame 11 for driving the connecting rod 12 to translate left and right. In this embodiment, the linear drive component 50 adopts a screw linear module, one end of the connecting rod 12 is connected to the slide seat of the screw linear module, and the other end of the connecting rod 12 is slidably connected to the frame 11.

[0023] The working principle of this embodiment is as follows: initially, the connecting rod is located at the right end of the frame 11 so that the magnet 20 is located above the left part of the conveyor belt 10. After the metal cans are packaged and tested, they are placed on the conveyor belt 10. The conveyor belt 10 conveys a batch of metal cans to the bottom of the magnet 20. Then, the telescopic rod of the cylinder 13 extends downward to drive the connecting frame 14 and the magnet 20 to descend until the isolation plate 22 of the magnet 20 is tightly attached to the top of the metal cans. At this time, the electric push rod 31 is used to push the metal cans to the bottom of the magnet 20. The telescopic rod extends, pushing the U-shaped rod 30 to move to the left. Under the meshing action of the rack 33 at the bottom of the U-shaped rod 30 and the gear 32 on the magnetic rod 231, the magnetic rod 231 is driven to rotate 90 degrees between the two magnetic yokes 232 and the two non-magnetic blocks 233, so that the N pole and S pole of the rotated magnetic rod 231 are respectively facing the two magnetic yokes 232, forming a closed magnetic line of force, thereby realizing the synchronous opening of the magnetic force of all magnetic groups 23, and then all magnetic groups 23 adsorb the metal cans through the isolation plate 22.

[0024] After the metal can is attracted by the magnet 20, the telescopic rod of the cylinder 13 is retracted upward, driving the connecting frame 14 and the magnet 20 to rise. Then, the connecting rod 12 is driven to translate to the left by the linear drive member 50 to move the metal can to the designated stacking position. After reaching the designated position, the telescopic rod of the cylinder 13 is extended downward again to place the metal can on the pallet or shelf. Then, the telescopic rod of the electric push rod 31 is retracted to drive the U-shaped rod 30 to move in the opposite direction and reset. Under the meshing action of the rack 33 and the gear 32, the magnetic rod 231 is driven between the two yokes 232 and the two non-magnetic The blocks 233 rotate in the opposite direction by 90 degrees. At this time, the N pole and S pole of the magnetic bar 231 are respectively facing the two non-magnetic blocks 233, so that the magnetic lines of force of the magnetic bar 231 form a closed circuit in the two magnetic yokes 232, and the magnetic forces of all the magnetic groups 23 are synchronously closed, so that the adsorption force generated by the magnetic group 23 on the metal cans through the isolation plate 22 is gradually reduced to zero, so that the metal cans are stably placed on the pallet or shelf, and the stacking of a batch of metal cans is completed. Subsequently, the linear drive member 50 and the cylinder 13 are successively moved in the opposite direction to reset to the initial position, preparing for the stacking operation of the next batch of metal cans.

[0025] When the weight of a batch of metal cans changes, the gap between the isolation plate 22 and the multiple magnetic groups 23 is adjusted by the lifting assembly. Specifically, the telescopic rod of the hydraulic cylinder 40 pushes or pulls the connecting rod 41, thereby driving the fixed rod 42 and the isolation plate 22 to move up and down on the isolation cover 21, so that the gap between the isolation plate 22 and the multiple magnetic groups 23 increases or decreases, thereby changing the adsorption force of the magnetic group 23 on the metal cans through the isolation plate 22, ensuring that it can be firmly adsorbed without damaging the can top.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
