Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, specifically a cylindrical battery core magnetic gripper. Background Technology

[0002] With the increasing severity of energy shortages and environmental degradation, the development of new energy industries has attracted widespread attention, especially in the field of new energy vehicles. The use of pure electric vehicles is a trend, and research on the production and application of power batteries is urgently needed.

[0003] In power batteries, cylindrical cells are the mainstream type, typically encapsulated in a cylindrical steel shell that can be magnetically attached. In existing technology, the grippers used to handle these cells during production can only grasp and move them when each cylindrical cell is precisely positioned. When the gaps between the cells and the gripper are inconsistent, the gripper itself cannot be used for proper positioning, significantly impacting production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic gripper for cylindrical batteries to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical battery core magnetic gripper, comprising a main cylinder, a rear cover plate installed on one side of the main cylinder, a transition ring installed on the other side of the main cylinder, a front cover plate installed on the side of the main cylinder near the transition ring, a movable cavity provided on one side of the interior of the main cylinder, a piston block movably connected inside the movable cavity, a piston rod connected to one side of the piston block, a sliding cavity provided on the other side of the interior of the main cylinder, a material-attracting permanent magnet movably installed inside the sliding cavity, a push-pull seat installed at one end of the piston rod, one side of the push-pull seat connected to one side of the material-attracting permanent magnet, an air intake port provided on one side of the front of the main cylinder, and an air release port provided on the other side of the front of the main cylinder.

[0006] Preferably, the rear cover plate is provided with a plurality of rear fixing bolts in the middle, and the rear cover plate is connected to the main cylinder body by the rear fixing bolts, which are used for the installation and fixing of the rear cover plate.

[0007] Preferably, the transition ring has a plurality of embedded bolts in the middle, and the transition ring is connected to the main cylinder body through the embedded bolts, which are used for the installation and fixing of the transition ring.

[0008] Preferably, the surface of the main cylinder body is provided with a plurality of mounting holes, and the interior of the mounting holes is provided with external fixing bolts. The front cover plate is connected to the transition ring through the external fixing bolts, and the external fixing bolts are used for mounting and fixing the front cover plate.

[0009] Preferably, both the intake port and the release port extend into the interior of the active cavity, with the intake port located on one side of the active cavity and the release port located on the other side of the active cavity.

[0010] Preferably, the front cover plate has a groove in the middle, a positioning shallow groove on the outside of the groove, and protruding corner blocks on all sides of the front cover plate.

[0011] Preferably, the top of the main cylinder is provided with a mounting groove, one end of the piston rod extends through the movable cavity into the interior of the sliding cavity, and the push-pull seat is located inside the sliding cavity. The push-pull seat is used to push and pull the material-attracting permanent magnet to move inside the sliding cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The intake port allows air to flow, pushing the piston block forward. The piston block then moves the piston rod and push-pull seat, causing the permanent magnet to move closer to the front cover. At this point, the permanent magnet is close to the workpiece and can pick it up. When air is released through the release port, it pushes the piston block backward inside the moving chamber, causing the permanent magnet to move away from the workpiece and release it. The entire magnetic gripper uses a combination of cylinder and magnetic attraction for material handling, which is convenient for gripping materials even when the gap between the battery and the gripper is inconsistent. This improves production efficiency, ensures stable operation of the production line, and demonstrates excellent performance in the gripping, handling, and assembly of automotive parts.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figure 1-4 This utility model provides a cylindrical battery core magnetic gripper, including a main cylinder 1, a rear cover plate 2 installed on one side of the main cylinder 1, a transition ring 3 installed on the other side of the main cylinder 1, a front cover plate 4 installed on the side of the main cylinder 1 near the transition ring 3, a movable cavity 8 provided on one side of the interior of the main cylinder 1, a piston block 10 movably connected inside the movable cavity 8, a piston rod 11 connected to one side of the piston block 10, a sliding cavity 9 provided on the other side of the interior of the main cylinder 1, a suction permanent magnet 13 movably installed inside the sliding cavity 9, a push-pull seat 12 installed at one end of the piston rod 11, one side of the push-pull seat 12 connected to one side of the suction permanent magnet 13, an air intake port 5 provided on one side of the front of the main cylinder 1, and an air release port 6 provided on the other side of the front of the main cylinder 1. Both the air intake port 5 and the air release port 6 extend into the interior of the movable cavity 8, with the air intake port 5 located on one side of the movable cavity 8 and the air release port 6 located on the other side of the movable cavity 8.

[0021] In this embodiment, when the front cover plate 4 is close to the battery cell, the suction port 5 is vented. The compressed gas will push the piston block 10 forward inside the movable cavity 8. The piston block 10 pushes the piston rod 11 and the push-pull seat 12 to move, thereby causing the suction permanent magnet 13 to move to the side closer to the front cover plate 4. At this time, the suction permanent magnet 13 is close to the workpiece and can pick up the workpiece and complete the product gripping action. When gas is introduced through the release port 6, it will push the piston block 10 backward inside the movable cavity 8, thereby causing the suction permanent magnet 13 to move away from the workpiece and complete the workpiece release action.

[0022] See Figure 1-4 The rear cover plate 2 is provided with several rear fixing bolts 14 in the middle, and the rear cover plate 2 is connected to the main cylinder body 1 through the rear fixing bolts 14. The transition ring 3 is provided with several embedded bolts 15 in the middle, and the transition ring 3 is connected to the main cylinder body 1 through the embedded bolts 15. The surface of the main cylinder body 1 is provided with several mounting holes 17. The mounting holes 17 are provided with external fixing bolts 16 inside, and the front cover plate 4 is connected to the transition ring 3 through the external fixing bolts 16.

[0023] In this embodiment, the rear cover plate 2 can be fixed to one side of the main cylinder 1 by the rear fixing bolt 14 to seal one end. The transition ring 3 can be fixed to the other side of the main cylinder 1 by the embedded bolt 15, and the front cover plate 4 can be connected to the transition ring 3 by the external fixing bolt 16.

[0024] See Figure 1-4 The front cover plate 4 has a groove 18 in the middle and a positioning shallow groove 19 on the outside of the groove 18. The front cover plate 4 has protruding corner blocks 7 on each corner. The top of the main cylinder 1 has a locking groove 20. One end of the piston rod 11 passes through the movable cavity 8 and extends into the interior of the sliding cavity 9. The push-pull seat 12 is located inside the sliding cavity 9.

[0025] In this embodiment, when the air intake port 5 is ventilated, the compressed gas will push the piston block 10 forward inside the movable chamber 8. The piston block 10 pushes the piston rod 11 and the push-pull seat 12 to move, thereby causing the suction permanent magnet 13 to move towards the side closer to the front cover plate 4. At this time, the suction permanent magnet 13 approaches and suctions the workpiece under the action of magnetic force.

[0026] In practical use, the cylindrical battery cell magnetic gripper of this utility model has its main cylinder 1 mounted on a robot arm, with the suction port 5 and release port 6 connected to an external air supply. A cylinder is used to push and pull the suction permanent magnet 13 inside the main cylinder 1. The front cover plate 4 is the suction end. During use, when the front cover plate 4 is close to the battery cell, air is released through the suction port 5. The compressed gas pushes the piston block 10 forward inside the movable chamber 8. The piston block 10 pushes the piston rod 11 and the push-pull seat 12 to move, thereby moving the suction permanent magnet 13 closer to the front cover plate 4. At this time, the suction permanent magnet 13 is close to the workpiece and can... The magnetic gripper picks up the workpiece and releases it. When gas is introduced through the air release port 6, it pushes the piston block 10 backward inside the movable chamber 8, thereby causing the permanent magnet 13 to move away from the workpiece and release it. The front cover 4 is an anti-static plastic conformal cover, which ensures positioning and cushioning while avoiding damage to the surface of the battery cell. The entire magnetic gripper uses a combination of cylinder and magnetic attraction to pick up materials, which is convenient for picking up materials when the gap between the battery and the gripper is inconsistent, improving production efficiency and ensuring the stable operation of the production line. It has demonstrated excellent performance in the picking, handling and assembly of automotive parts.
