Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and more specifically, to a lithium battery cell clamping device with a wide range of applications and tight fit. Background Technology

[0002] Lithium-ion battery cell compaction is a core step in the battery pack assembly process. Essentially, it uses mechanical force to fix the cells in an orderly manner, ensuring the structural strength of the module, the stability of electrical connections, and the efficiency of thermal management. Against the backdrop of the rapid development of the new energy industry, the importance of the compaction process continues to increase with the diversification of cell specifications, such as square, cylindrical, and pouch cells, as well as the demand for high energy density in battery systems.

[0003] In the field of lithium battery cascade utilization, the cell packing process faces challenges that are completely different from those of new cells. Due to the complex sources of retired cells and their significant individual differences, such as varying dimensional tolerances and aging levels, it is difficult to achieve tight bonding through standardized production lines like with new cells. In the cell placement stage, retired cells may have deformed shells, damaged tabs, or worn surface coatings due to previous use. In addition, the positioning accuracy is insufficient during manual sorting or semi-automatic assembly, which can easily lead to problems such as misalignment and uneven spacing. These irregularities can directly cause multiple deviations in the pressing process. Furthermore, the uneven arrangement of cells can also lead to uneven stress distribution inside the pack. During long-term cyclic use, stress concentration may accelerate cell aging, thus requiring improvement and optimization. Utility Model Content

A pressure sensor is fixedly installed on the side of the push protrusion. A fixed plate frame is fixedly installed on the top of the tooling support plate and is located at the far end of the fixed tooling block. A touch controller is fixedly installed on the top of the clamping machine frame.

[0006] As a preferred embodiment of this utility model, an auxiliary pushing assembly is fixedly installed on the top of the fixed tooling block. The auxiliary pushing assembly includes a fixed plate fixedly installed on the top of the fixed tooling block. A fixed collar is welded to the top of the fixed plate. A linkage rod is movably sleeved on the inner side of the fixed collar, and one end of the linkage rod is fixedly connected to the side of the pushing plate. A second hinge is hinged to the outer surface of the fixed plate. The other end of the linkage rod is hinged to the second hinge through a first hinge. A horizontal detection rod is fixedly installed on the inner side of the second hinge.

[0007] As a preferred technical solution of this utility model, the electric cylinder extrusion assembly includes electric cylinders fixedly installed on both sides of the top of the clamping machine frame, a stacking slide rail fixedly installed on the top of the tooling support plate, an extrusion transmission plate fixedly installed at the output end of the electric cylinder, connecting aluminum strips fixedly installed on both sides of the extrusion transmission plate, and a transmission extrusion block slidably installed on the top of the touch controller and located on the sides of the two stacking slide rails.

[0008] As a preferred embodiment of this utility model, a retaining strip is slidably installed on the outer surface of the connecting aluminum strip, and the retaining strip is C-shaped.

[0009] As a preferred embodiment of this utility model, the tooling frame is C-shaped, and the diameter of the tooling frame is larger than the diameter of the tooling support plate.

[0010] As a preferred embodiment of this utility model, an electric cylinder protective box is fixedly installed on the top of the clamping machine frame, and the electric cylinder is located inside the electric cylinder protective box, but the output end of the electric cylinder is not provided with an electric cylinder protective box.

[0011] As a preferred embodiment of the present invention, a bogie is rotatably mounted on the bottom of the clamping machine frame, and the bogie is rotatably mounted around the bottom of the clamping machine frame, with rollers rotatably mounted on the inner side of the bogie.

[0012] As a preferred embodiment of this utility model, a threaded rod is fixedly installed at the bottom of the clamping machine frame, a nut is threaded onto the outer surface of the threaded rod, and a base is fixedly installed at the bottom of the nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves workers placing lithium battery cells inside two electric cylinder extrusion components. The cylinder then drives the connecting rod, which, through a multi-link transmission structure, synchronously moves the pushing plate, connecting plate, pushing protrusions, springs, and extrusion protrusions towards the stacked lithium battery cells. The non-parallel extrusion protrusions first contact the lithium battery cells. The directional force applied by the fixed plate causes the springs to elastically deform, adaptively adjusting the gaps between the lithium battery cells while achieving three-dimensional alignment. This ensures no offset in the stacking column direction or between layers. When the extrusion protrusions reach contact with the pressure sensor, the cylinder stops, and the lithium battery cells are precisely positioned. At this point, the extrusion protrusions and the pushing plate become parallel, forming a planar leveling component that synchronously compacts the top of the lithium battery cells, eliminating stacking discrepancies. This device, through elastic deformation compensation and multi-directional force application mechanisms, avoids damage or poor contact of lithium battery cells caused by uneven force in traditional manual operations, significantly improving stack tightness and consistency, laying the foundation for subsequent compaction. Simultaneously, automated leveling greatly improves production efficiency.

[0015] 2. This utility model achieves intelligent judgment and efficient calibration of stacking accuracy through a linkage structure design. When the pusher plate moves towards the stacked lithium battery cells, it drives the linkage rod to move synchronously, which in turn pulls the second hinge to rotate through the first hinge, so that the horizontal detection rod gradually approaches the lithium battery cell. By checking whether the two horizontal detection rods contact the lithium battery cell synchronously, the neatness of the stack can be quickly determined: if they contact synchronously, it indicates that the lithium battery cells are arranged neatly; if there is a difference in timing, it indicates that there is a deviation or tilt. This real-time detection mechanism provides data feedback for the precise pushing of the pusher assembly, ensuring that dynamic adjustments are made to the uneven areas during the leveling process, avoiding the deformation of the lithium battery cells due to blind force application, while optimizing the production process and improving the consistency and yield of lithium battery cell compaction.

[0016] 3. This utility model uses a touch controller to activate the electric cylinders on both sides to drive the extrusion transmission plate and the extrusion blocks to synchronously approach the stacked lithium battery cells. Two sets of four extrusion blocks symmetrically extrude the lithium battery cells from both sides. The design of multiple force points allows for adaptive adjustment of pressure distribution according to the specifications of the lithium battery cells, precisely controlling the clamping force. This avoids damage to the lithium battery cells due to overpressure and ensures a tight fit between the cells, solving the problem of poor adhesion that often occurs with traditional single-point clamping. Furthermore, the modular structure of the extrusion blocks enhances the equipment's compatibility with stacked lithium battery cells of different sizes, allowing it to adapt to diverse production needs without frequent tooling changes. This reduces debugging time and costs, improves production efficiency, and provides a reliable guarantee for the high-quality, standardized assembly of lithium battery cells.

Detailed Implementation

[0025] 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.

[0026] like Figures 1 to 7 As shown, this utility model provides a widely applicable and tightly fitting lithium battery cell clamping device, including a clamping machine frame 1 and a lithium battery cell 8. Electric cylinder extrusion assemblies 2 are fixedly installed on both sides of the top of the clamping machine frame 1. A tooling plate frame 5 is fixedly installed on the top of the clamping machine frame 1. A tooling support plate 7 is fixedly installed on the top of the tooling plate frame 5. A pushing and adjusting assembly 3 is fixedly installed on the top of the tooling support plate 7. The pushing and adjusting assembly 3 includes a fixing tooling block 301 fixedly installed on the top of the tooling support plate 7, with the fixing tooling block 301 located on both sides of the top of the tooling support plate 7. A cylinder 302 is fixedly installed on the top of the fixing tooling block 301. The output end of the cylinder 302 is fixed... A connecting rod 303 is fixedly connected to the two connecting rods 303. A push plate 305 is fixedly installed at the ends of the two connecting rods 303. A connecting plate 304 is fixedly sleeved on the outer surface of the connecting rod 303. A push protrusion 306 is fixedly installed on one side of the connecting plate 304 and is located above the push plate 305. A spring 307 is fixedly connected to one side of the push protrusion 306 and is arranged in a linear array. A compression protrusion 308 is fixedly connected to the other end of the spring 307. A pressure sensor 309 is fixedly installed on the side of the push protrusion 306. A fixed plate frame 310 is fixedly installed on the top of the tooling support plate 7 and is located at the far end of the fixed tooling block 301. A touch controller 6 is fixedly installed on the top of the clamping machine frame 1.

[0027] When the worker places the lithium battery cells that need to be tightly fitted into the inside of the two electric cylinder pressing components 2, before the electric cylinder pressing components 2 press tightly, the two cylinders 302 are activated via the touch controller 6. Then, the output end of the cylinder 302 drives the connecting rod 303 to move towards the stacked lithium battery cells 8. The connecting rod 303 then drives the pushing plate 305 to gradually move towards the stacked lithium battery cells 8. The movement of the connecting rod 303 causes the connecting plate 304 to move synchronously. When the connecting plate 304 moves synchronously, it drives the pushing ridge 306 to move. When the pushing ridge 306 moves, it drives the pressing ridge 308 to move via the spring 307. The stacked lithium battery cells 8 move. When the push plate 305 and the extrusion ridge 308 contact the lithium battery cells 8, and since the extrusion ridge 308 does not protrude parallel to the push plate 305, and the extrusion ridge 308 makes the stacked lithium battery cells 8 neat, the fixing plate 310 applies a directional force at the same time, which will cause the spring 307 to undergo elastic deformation. Then, when the extrusion ridge 308 contacts the pressure sensor 309, the stacked lithium battery cells 8 are in a neat state. At the same time, when the extrusion ridge 308 and the push plate 305 are in a parallel state, the push plate 305 will assist the extrusion ridge 308 in leveling the lithium battery cells 8.

[0028] After the staff places the lithium battery cell 8 inside the two electric cylinder extrusion components 2, the cylinder 302 is activated to drive the connecting rod 303. Through the multi-link transmission structure, the pushing plate 305, the connecting plate 304, the pushing protrusion 306, the spring 307, and the extrusion protrusion 308 are moved towards the stacked lithium battery cell 8. The non-parallel protruding extrusion protrusion 308 contacts the lithium battery cell 8 first. The directional force applied by the fixed plate frame 310 causes the spring 307 to undergo elastic deformation, which adaptively adjusts the gap between the lithium battery cells 8 and completes the three-dimensional alignment, ensuring that there is no misalignment in the stacking column direction and between layers. When the extrusion protrusion 308 moves to contact the pressure sensor 309, the cylinder 302 stops operating, and the lithium battery cell 8 has achieved precise positioning. At this time, the extrusion protrusion 308 and the push plate 305 tend to be parallel, and the two form a planar leveling component to synchronously compact the top of the lithium battery cell 8, eliminating stacking differences. This device avoids damage to the lithium battery cell 8 or poor contact caused by uneven force in traditional manual operation through elastic deformation compensation and multi-directional force application mechanism, significantly improving the stacking tightness and consistency, laying the foundation for subsequent compaction, and greatly improving production efficiency through automated leveling.

[0029] The top of the fixed tooling block 301 is fixedly installed with an auxiliary pushing assembly 4. The auxiliary pushing assembly 4 includes a fixed plate 401 fixedly installed on the top of the fixed tooling block 301. A fixed collar 402 is welded to the top of the fixed plate 401. A linkage rod 403 is movably sleeved on the inner side of the fixed collar 402, and one end of the linkage rod 403 is fixedly connected to the side of the pushing plate 305. A second hinge member 405 is hinged to the outer surface of the fixed plate 401. The other end of the linkage rod 403 is hinged to the second hinge member 405 through a first hinge member 404. A horizontal detection rod 406 is fixedly installed on the inner side of the second hinge member 405.

[0030] As the pusher plate 305 gradually moves toward the stacked lithium battery cells 8, it will drive the linkage rod 403 to gradually move in the direction of the pusher plate 305. Then, the linkage rod 403 will drive the first hinge 404 to pull the second hinge 405 downward. When the second hinge 405 rotates downward, it will drive the horizontal detection rod 406 to gradually approach the lithium battery cells 8. Then, by checking whether the two horizontal detection rods 406 simultaneously contact the lithium battery cells 8, it can be determined whether the stacked lithium battery cells 8 are neatly arranged. This can help the pusher assembly 3 to better push the neatly stacked lithium battery cells 8.

[0031] Through a linkage structure design, intelligent judgment and efficient calibration of stacking accuracy are achieved. When the pusher plate 305 moves toward the stacked lithium battery cells 8, it drives the linkage rod 403 to move synchronously. Then, the first hinge 404 pulls the second hinge 405 to rotate, so that the horizontal detection rod 406 gradually approaches the lithium battery cell 8. By checking whether the two horizontal detection rods 406 contact the lithium battery cell 8 synchronously, it is possible to quickly determine whether the stacking is neat: if they contact synchronously, it indicates that the lithium battery cells 8 are arranged neatly; if there is a difference in timing, it indicates that there is a shift or tilt. This real-time detection mechanism provides data feedback for the precise pushing of the pusher assembly 3, ensuring that dynamic adjustments are made to the uneven areas during the leveling process, avoiding the deformation of the lithium battery cells 8 due to blind force application, while optimizing the production process and improving the consistency and yield of the lithium battery cells 8.

[0032] The electric cylinder extrusion assembly 2 includes electric cylinders 201 fixedly installed on both sides of the top of the clamping machine frame 1, stacking slide rails 205 fixedly installed on the top of the tooling support plate 7, extrusion transmission plate 202 fixedly installed at the output end of the electric cylinder 201, connecting aluminum strips 203 fixedly installed on both sides of the extrusion transmission plate 202, and transmission extrusion block 206 slidably installed on the top of the touch controller 6 and located on the sides of the two stacking slide rails 205.

[0033] When the touch controller 6 activates the electric cylinders 201 on both sides, the output ends of the electric cylinders 201 will drive the extrusion transmission plate 202 to gradually approach the neatly stacked lithium battery cell 8. At the same time, the lithium battery cell 8 is located above the two stacking slide rails 205. Then, the extrusion transmission plate 202 gradually moves and drives the transmission extrusion block 206 to approach the lithium battery cell 8. Then, the two sets of four transmission extrusion blocks 206, two on each side, extrude the neatly stacked lithium battery cells 8. This increases the compatibility of the equipment and can accurately compress the stacked lithium battery cells 8, ensuring a tight fit between the lithium battery cells 8. This avoids the previous problems of overpressure and the inability to tightly fit the stacked lithium battery cells 8. The electric cylinder 201 stacking and extrusion has a pressure of 1T±1kg. The module is compatible with the following dimensions: length 300-1200mm x width 150-500mm x height 100-300mm.

[0034] The touch controller 6 activates the electric cylinders 201 on both sides, driving the extrusion transmission plate 202 to simultaneously move the extrusion blocks 206 closer to the stacked lithium battery cells 8. Two sets of four extrusion blocks 206 symmetrically extrude the lithium battery cells 8 from both sides. The design of multiple force points allows for adaptive adjustment of pressure distribution according to the specifications of the lithium battery cells 8, precisely controlling the clamping force. This avoids damage to the lithium battery cells 8 due to overpressure while ensuring a tight fit between the cells, solving the problem of poor adhesion that often occurs with traditional single-point clamping. Simultaneously, the modular structure of the extrusion blocks 206 enhances the equipment's compatibility with stacks of lithium battery cells 8 of different sizes, allowing it to adapt to diverse production needs without frequent tooling changes. This reduces debugging time and costs, improves production efficiency, and provides a reliable guarantee for the high-quality, standardized assembly of the lithium battery cells 8.

[0035] Among them, a retaining strip 204 is slidably installed on the outer surface of the connecting aluminum strip 203, and the retaining strip 204 is C-shaped.

[0036] The movement of the extrusion transmission plate 202 will drive the connecting aluminum strip 203 to move. When the connecting aluminum strip 203 moves, it will drive the clamping strip 204 to move. At the same time, the clamping strip 204 is slidably installed on the outer surface of the connecting aluminum strip 203. This allows the extrusion range of the extrusion transmission plate 202 to be adjusted according to the size of the lithium battery cell 8, thereby enhancing its applicability.

[0037] The tooling frame 5 is C-shaped, and the diameter of the tooling frame 5 is larger than the diameter of the tooling support plate 7.

[0038] The tooling frame 5 is C-shaped, and its diameter is larger than that of the tooling support plate 7, which can effectively support the stacked lithium battery cells 8 of the electric cylinder extrusion assembly 2.

[0039] The top of the clamping machine frame 1 is fixedly installed with an electric cylinder protection box 9, and the electric cylinder 201 is located inside the electric cylinder protection box 9, but the output end of the electric cylinder 201 is not provided with an electric cylinder protection box 9.

[0040] By placing the electric cylinder 201 inside the electric cylinder protection box 9 and not installing the electric cylinder protection box 9 at the output end of the electric cylinder 201, the electric cylinder 201 can be effectively physically protected, avoiding easy physical damage from the outside.

[0041] The bottom of the clamping machine frame 1 is rotatably mounted with a bogie 13, and the bogie 13 is rotatably mounted around the bottom of the clamping machine frame 1. Rollers 14 are rotatably mounted on the inner side of the bogie 13.

[0042] The bogie 13 is rotatably mounted around the bottom of the clamping machine frame 1, and rollers 14 are rotatably mounted on the inner side of the bogie 13, which can enhance the flexibility of the entire device.

[0043] Among them, a threaded rod 10 is fixedly installed at the bottom of the clamping machine frame 1, a nut 11 is threaded onto the outer surface of the threaded rod 10, and a base 12 is fixedly installed at the bottom of the nut 11.

[0044] A nut 11 is threaded onto the outer surface of the threaded rod 10, and a base 12 is fixedly installed at the bottom of the nut 11. When the entire device needs to be moved, the base 12 can be rotated upwards, and then the base 12 will drive the nut 11 to rotate, so that the roller 14 contacts the ground. When it is necessary to fix the device, the base 12 can be rotated downwards to make it contact the ground, thereby fixing the entire device.

[0045] Working principle and usage process of this utility model:

[0046] When the worker places the lithium battery cells that need to be tightly fitted into the inside of the two electric cylinder pressing components 2, before the electric cylinder pressing components 2 press tightly, the two cylinders 302 are activated via the touch controller 6. Then, the output end of the cylinder 302 drives the connecting rod 303 to move towards the stacked lithium battery cells 8. The connecting rod 303 then drives the pushing plate 305 to gradually move towards the stacked lithium battery cells 8. The movement of the connecting rod 303 causes the connecting plate 304 to move synchronously. When the connecting plate 304 moves synchronously, it drives the pushing ridge 306 to move. When the pushing ridge 306 moves, it drives the pressing ridge 308 to move via the spring 307. The stacked lithium battery cells 8 move. When the push plate 305 and the extrusion ridge 308 contact the lithium battery cells 8, and since the extrusion ridge 308 does not protrude parallel to the push plate 305, and the extrusion ridge 308 makes the stacked lithium battery cells 8 neat, the fixing plate 310 applies a directional force at the same time, which will cause the spring 307 to undergo elastic deformation. Then, when the extrusion ridge 308 contacts the pressure sensor 309, the stacked lithium battery cells 8 are in a neat state. At the same time, when the extrusion ridge 308 and the push plate 305 are in a parallel state, the push plate 305 will assist the extrusion ridge 308 in leveling the lithium battery cells 8.

[0047] As the pusher plate 305 gradually moves toward the stacked lithium battery cells 8, it will drive the linkage rod 403 to gradually move in the direction of the pusher plate 305. Then, the linkage rod 403 will drive the first hinge 404 to pull the second hinge 405 downward. When the second hinge 405 rotates downward, it will drive the horizontal detection rod 406 to gradually approach the lithium battery cells 8. Then, by checking whether the two horizontal detection rods 406 simultaneously contact the lithium battery cells 8, it can be determined whether the stacked lithium battery cells 8 are neatly arranged. This can help the pusher assembly 3 to better push the neatly stacked lithium battery cells 8.

[0048] When the touch controller 6 activates the electric cylinders 201 on both sides, the output ends of the electric cylinders 201 will drive the extrusion transmission plate 202 to gradually approach the neatly stacked lithium battery cell 8. At the same time, the lithium battery cell 8 is located above the two stacking slide rails 205. Then, the extrusion transmission plate 202 gradually moves and drives the transmission extrusion block 206 to approach the lithium battery cell 8. Then, the two sets of four transmission extrusion blocks 206, two on each side, extrude the neatly stacked lithium battery cells 8. This increases the compatibility of the equipment and can accurately compress the stacked lithium battery cells 8, ensuring a tight fit between the lithium battery cells 8. This avoids the previous problems of overpressure and the inability to tightly fit the stacked lithium battery cells 8. The electric cylinder 201 stacking and extrusion has a pressure of 1T±1kg. The module is compatible with the following dimensions: length 300-1200mm x width 150-500mm x height 100-300mm.
