Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery cell processing equipment, and in particular to lithium battery pack clamps. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They convert chemical energy into electrical energy by the movement of lithium ions between the positive and negative electrodes, offering advantages such as high energy density. A lithium-ion battery pack combines multiple individual lithium-ion batteries and is equipped with components such as a battery management system to meet specific voltage, capacity, and power output requirements. Their applications are widespread, covering consumer electronics, new energy vehicles, energy storage, and many other fields. Clamps are needed in the lithium-ion battery manufacturing process because they ensure processing precision, allowing for accurate positioning and fixation of battery components during cutting, welding, and other processes; they improve production efficiency, facilitate rapid operation of automated equipment, and ensure operational safety, preventing accidents caused by battery movement.

[0003] Lithium-ion battery pack grippers typically consist of mechanical fingers, a drive mechanism, connecting components, and a control unit. Their working principle involves the control unit receiving commands, the drive mechanism instructing the mechanical fingers to open and close, and the connecting components ensuring stable connection and force transmission between the gripper parts. During the opening and closing process, the mechanical fingers grasp, secure, or release the lithium-ion battery pack, thereby precisely positioning and stably clamping the battery pack during production, testing, and assembly, ensuring accuracy and safety in processing and operation.

[0004] In existing technologies, due to the diverse sizes and shapes of lithium battery packs, grippers are difficult to adjust automatically and quickly, making it difficult for some grippers to perform adaptive and non-destructive clamping and fixing of lithium battery packs. This results in positional displacement of the lithium battery pack during processing, affecting processing accuracy and product quality. Furthermore, improper clamping force can damage the battery pack, causing safety hazards and reducing product yield. Therefore, lithium battery pack grippers are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lithium battery pack clamp, which aims to improve the problem that some clamps in the prior art are difficult to adaptively and non-destructively clamp and fix lithium battery packs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lithium battery pack clamp includes a drive shaft, a drive mechanism fixedly connected to the bottom of the drive shaft, two electric slide rails fixedly connected to the bottom of the drive mechanism, a lubrication mechanism fixedly connected to the top of the electric slide rails, two sliders slidably connected to the bottom of the electric slide rails, a drive rod fixedly connected to the bottom of the sliders, a clamping block fixedly connected to the adjacent side of each of the two drive rods, and an adaptive clamping mechanism fixedly connected to the outer wall of the clamping block.

[0008] The adaptive clamping mechanism includes an air box, the outer wall of which is fixedly connected to the outer wall of the clamping block, a plurality of fixed cylinders fixedly connected to the output end of the air box, a transmission cylinder fixedly connected to the other side of the fixed cylinder, a piston slidably connected to the inner wall of the fixed cylinder, a spring fixedly connected to the outer wall of the piston, and a protective component fixedly connected to the other end of the spring.

[0009] As a further description of the above technical solution:

[0010] The protective component includes a compression block, one side of which is fixedly connected to the other end of the spring, and the other side of the compression block is fixedly connected to a soft body, and the other side of the soft body is fixedly connected to a silicone head.

[0011] As a further description of the above technical solution:

[0012] The lubrication mechanism includes multiple oil tanks. The tops of two oil tanks are fixedly connected to the top of the electric slide rail. A fixed plate is fixedly connected to the bottom of each oil tank. A sliding plate is slidably connected inside the fixed plate. A spring is fixedly connected to one end of the sliding plate. An abutment block is fixedly connected to the bottom of the sliding plate. A transmission block is fixedly connected to the top of the slide rail.

[0013] As a further description of the above technical solution:

[0014] The drive mechanism includes a transmission platform, the top of which is fixedly connected to the top of the transmission shaft, and a support platform is fixedly connected to the bottom of the transmission platform. Two air pumps are installed inside the support platform, and a lifting column is fixedly connected to the output end of the air pumps. The top of the electric slide rail is fixedly connected to the bottom of the lifting column.

[0015] As a further description of the above technical solution:

[0016] The other end of the second spring is fixedly connected to the inside of the electric slide rail, and the top of the sliding plate is slidably connected to the bottom of the oil tank;

[0017] As a further description of the above technical solution:

[0018] Oil passage holes are provided at the bottom of the oil tank and inside the fixed plate, and an absorbent sponge is provided on the inner side of the electric slide rail.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the silicone head and the soft body first contact the outer surface of the battery pack. Its deformation ability drives the extrusion block to move inward. The extrusion block compresses the spring and then drives the piston to move inward, so that the clamping part adapts to the irregular surface of the battery pack. Subsequently, the air box operates to inflate the fixed cylinder with air. The air pressure drives the piston to move and maintain force balance, thereby achieving self-locking after adaptive clamping. This realizes adaptive non-destructive clamping and fixing of the lithium battery pack, ensuring that the internal structure of the lithium battery pack is not disturbed by external forces, maintaining its performance stability and safety, extending the service life of the lithium battery, and avoiding damage such as scratches and collisions, thus improving the product qualification rate.

[0025] 2. In this utility model, during the clamping process of the gripper, the slider moves and drives the transmission block to move synchronously. The transmission block drives the abutment block to slide against the sliding plate and stretches the second spring to open the oil tank for lubrication. The slider continues to move, causing the abutment block to deform. After the transmission block and the abutment block separate, the second spring drives the sliding plate to reset and close the oil tank, completing automatic lubrication. This achieves automatic lubrication of the gripper during the clamping process, thereby ensuring smooth movement of the gripper, improving the accuracy and response speed of the clamping action, enhancing the stability and continuity of the production process, and reducing production interruptions caused by gripper jamming or malfunction.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a lithium battery pack gripper, including a drive shaft 1. The drive shaft 1 serves as the power transmission hub for the entire gripper, driving the subsequent structure to move synchronously. A drive mechanism is fixedly connected to the bottom of the drive shaft 1, providing precise and stable vertical driving force to the gripper, allowing the gripper to flexibly adjust its height according to actual production needs. The drive mechanism includes a drive platform 2, the top of which is fixedly connected to the top of the drive shaft 1. The drive shaft 1 stably transmits power from the drive shaft 1 to the subsequent structure below. A support platform 3 is fixedly connected to the bottom of the drive platform 2, serving as the main support structure for the drive mechanism and providing a stable support platform for the installation of the subsequent structure. Two air pumps 4 are installed inside the support platform 3, with lifting columns 5 fixedly connected to the output ends of the air pumps 4. By operating the air pumps 4 to compress air, the energy of the gas is converted into mechanical energy, thereby driving the lifting columns 5 to move up and down, thus driving the subsequent gripper to adjust its height. The top of an electric slide rail 6 is fixedly connected to the bottom of the lifting column 5.

[0034] Two electric slide rails 6 are fixedly connected to the bottom of the drive mechanism. These rails provide a horizontal movement basis for the subsequent gripper, allowing the gripper to accurately align with both sides of the lithium battery pack, providing a precise positioning basis for subsequent clamping operations. A lubrication mechanism is fixedly connected to the top of the electric slide rails 6, ensuring smooth operation during prolonged, high-frequency use. Two sliders 23 are slidably connected to the bottom of the electric slide rails 6. These sliders 23 conform to the slide rail surface, converting the linear motion of the electric slide rails 6 into their own horizontal displacement and transmitting this displacement to the structure below. A transmission rod 8 is fixedly connected to the bottom of each slider 23. A clamping block 9 is fixedly connected to each adjacent side of the two transmission rods 8. The transmission rods 8 act as a bridge connecting the sliders 23 and the clamping blocks 9, accurately transmitting the horizontal movement of the sliders 23 to the clamping blocks 9, ensuring that the clamping blocks 9 can open and close synchronously and stably in the horizontal direction, achieving reliable clamping of the lithium battery pack. An adaptive clamping mechanism is fixedly connected to the outer wall of the clamping blocks 9.

[0035] The adaptive clamping mechanism includes an inflation box 10, the outer wall of which is fixedly connected to the outer wall of the clamping block 9. The inflation box 10 provides a stable high-pressure gas supply for the entire adaptive clamping process, enabling the entire clamping mechanism to maintain a stable clamping state after adapting to the external shape of the battery pack. Multiple fixed cylinders 11 are fixedly connected to the output end of the inflation box 10. The inflation box 10 is used to fill the fixed cylinders 11 with high-pressure gas, and the fixed cylinders 11 provide a stable base for subsequent structures. A transmission cylinder 14 is fixedly connected to the other side of the fixed cylinder 11. The transmission cylinder 14 extends the internal space of the fixed cylinder 11, allowing the entire adaptive adjustment structure to adapt to larger battery packs. A piston 12 is slidably connected to the inner wall of the fixed cylinder 11. The piston 12 transmits power from the structure in contact with the battery pack, thereby compressing air and causing the inflation box 10 to automatically inflate the fixed cylinder 11 to achieve locking. A spring 13 is fixedly connected to the outer wall of the piston 12, providing reset power for subsequent structures. The other end of spring 13 is fixedly connected to a protective component.

[0036] The protective assembly includes a clamping block 15, one side of which is fixedly connected to the other end of a spring 13. The clamping block 15 provides a mounting base and a sliding base for subsequent structures. The outer wall of the clamping block 15 is slidably connected to the inside of the transmission cylinder 14. A flexible body 16 is fixedly connected to the other side of the clamping block 15, and a silicone head 17 is fixedly connected to the other side of the flexible body 16. The flexible body 16 and the silicone head 17 directly contact the outer wall of the battery pack, thereby using their own deformation capabilities to make the entire clamping mechanism fit the outer surface of the battery pack more closely. Due to the soft materials of both, the outer surface of the battery pack is not easily damaged during clamping.

[0037] Reference Figure 1 , Figure 3 , Figure 4 The lubrication mechanism includes multiple oil tanks 7. The tops of two oil tanks 7 are fixedly connected to the top of the electric slide rail 6. The oil tanks 7 are used to store the lubricating oil required for the opening and closing of the entire clamping mechanism. A fixed plate 18 is fixedly connected to the bottom of the oil tank 7, which provides a sliding base for subsequent structures. A sliding plate 19 is slidably connected inside the fixed plate 18, and the top of the sliding plate 19 is slidably connected to the bottom of the oil tank 7. The sliding plate 19 is used to control the opening and closing of the oil tank 7. When the sliding plate 19 is fully in contact with the oil tank 7, the oil tank 7 is closed. When the sliding plate 19 is misaligned with the oil tank 7, the oil tank 7 supplies lubricating oil outward. A spring 20 is fixedly connected to one end of the sliding plate 19, and the other end of the spring 20 is fixedly connected to the inside of the electric slide rail 6. The spring 20 provides a return power base for the sliding plate 19. A contact block 21 is fixedly connected to the bottom of the sliding plate 19. The contact block 21 transmits the movement of the subsequent structure to the sliding plate 19. Because the contact block 21 has deformation capability, it can deform at a specific position to disengage the transmission relationship. A transmission block 22 is fixedly connected to the top of the slider 23. The transmission block 22 transmits the movement of the slider 23 to the contact block 21, thereby driving the sliding plate 19 to move, thus controlling the opening and closing of the oil tank 7. Oil passage holes are provided at the bottom of the oil tank 7 and inside the fixed plate 18 for the introduction of lubricating oil. An absorbent sponge is provided on the inner side of the electric slide rail 6. The outer wall of the slider 23 contacts the absorbent sponge, and the outer wall of the transmission block 22 is slidably connected to the inside of the absorbent sponge. The absorbent sponge can absorb and store the lubricating oil flowing out of the oil tank 7, allowing it to be evenly applied when the slider 23 moves, thus providing lubrication for the horizontal sliding of the entire clamping mechanism.

[0038] Working principle: During use, the air pump 4 is started, which drives the entire gripper to rise and fall to adapt to battery packs of different heights. Then, the electric slide rail 6 is opened, and the operation of the electric slide rail 6 drives the entire slider 23 to move horizontally. The movement of the slider 23 drives the clamping block 9 to move in opposite directions through the transmission rod 8, thereby completing the clamping operation of the battery pack. During the clamping process, the silicone head 17 and the soft body 16 first contact the surface of the battery pack. The deformation ability of the silicone head 17 makes the clamping mechanism fit the surface of the battery pack more closely. The force of the silicone head 17 transmits power to the extrusion block 15, causing the extrusion block 15 to move inward and compress the spring 13. After the spring 13 is compressed, it drives the piston 12 to move inward, so that the entire clamping part can adapt to the irregular surface of the battery pack. Then, the air box 10 operates to inflate the fixed cylinder 11. The air pressure makes the piston 12 maintain force balance after movement to maintain stability.

[0039] During the clamping process, the movement of slider 23 drives the transmission block 22 to move synchronously and contact the abutment block 21, thereby causing the abutment block 21 to slide synchronously with the sliding plate 19 and stretching the second spring 20, thus opening the entire oil tank 7. The oil tank 7 introduces lubricating oil into the absorbent sponge, and the movement of slider 23 ensures that the lubricating oil is evenly spread, thus ensuring that the movement of the entire gripper remains smooth. When the sliding plate 19 moves to the corresponding position, the restriction of the fixed plate 18 causes the sliding plate 19 to stop moving. At this time, the slider 23 continues to move, causing the abutment block 21 to deform until the transmission block 22 separates from the abutment block 21. The deformation recovery ability of the second spring 20 causes the entire sliding plate 19 to reset and close the oil tank 7, thus realizing automatic lubrication after the gripper releases the object. In the next clamping operation, the restriction of the fixed plate 18 causes the abutment block 21 to deform directly after contacting the transmission block 22, thus allowing slider 23 to move continuously in opposite directions, preventing the movement of the gripper from being restricted.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
