Description

Technical Field

[0001] This utility model relates to a battery cell shaping mechanism, belonging to the field of battery cell production and processing technology. Background Technology

[0002] New energy power batteries possess environmentally friendly, efficient, and sustainable technical characteristics, representing a significant trend in contemporary social development with broad application prospects. During the production process, power batteries typically employ winding or stacking methods to assemble positive electrode sheets, separators, and negative electrode sheets into cells, which are then baked. During this process, to ensure the alignment of the positive electrode sheets, separator, and negative electrode sheets, a certain tension must be applied to the separator. This tension causes the separator to elongate in the belt direction, compressing the electrode sheets. This results in poor cell surface flatness and internal separator wrinkles, leading to quality issues such as low capacity, poor cycle performance, and rapid self-discharge. This deformation problem is particularly pronounced in thicker wound cells. Furthermore, the inconsistent thickness of deformed cells increases the difficulty of cell assembly into the casing, potentially causing damage during assembly. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a cell shaping mechanism for pressing and shaping cells. This shaping mechanism is compatible with cells of different sizes, has a simple structure, and can improve the flatness of the cells, eliminate separator wrinkles, and ensure that the cell thickness meets the requirements of the cell casing process. It also prevents damage to the cells during casing, helps to reduce the internal resistance of the battery, improves the battery's process performance, increases production efficiency, and realizes automated production.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a battery cell shaping mechanism, including a conveying device, a pressing device, and a positioning device;

[0006] The conveying device is installed below the pressing device to convey the battery cells to the pressing station and output the battery cells after the operation is completed;

[0007] The positioning device is installed on the side of the pressing device to position the battery cell at the pressing position;

[0008] The clamping device is used to perform clamping and shaping operations on the battery cells.

[0009] In the above technical solution, the conveying device enables continuous flow of battery cells from feeding to discharging, the pressing device completes the core shaping action, and the positioning device ensures high-precision alignment of the battery cells at the pressing station. These three components are vertically layered and laterally linked in space, reducing equipment footprint and shortening operation time through process integration. The coordinated layout of the conveying, pressing, and positioning devices constructs a fully automated battery cell shaping system, achieving an integrated operation process of automatic cell conveying, precise positioning, and efficient pressing, improving shaping efficiency while ensuring process stability. Furthermore, the modular design facilitates separate maintenance, reduces downtime, and is suitable for large-scale power battery production scenarios.

[0010] Furthermore, the conveying device includes a connecting plate, a power assembly and a roller assembly mounted on the connecting plate, and a conveyor belt wound around the roller assembly; a brush cleaning assembly is provided below the return section of the conveyor belt, and a dust collection component is provided below the brush cleaning assembly.

[0011] In the above technical solution, the brush cleaning component of the conveyor belt and the dust collection component form a closed-loop cleaning system, which effectively removes dust and impurities generated during the conveying process, prevents pollutants from re-entering the cell processing area, ensures the cleanliness of the cell surface and avoids the risk of short circuit caused by foreign objects on the cell surface, reduces the frequency of manual cleaning and equipment maintenance, and improves the stability of continuous operation of the production line.

[0012] Furthermore, the roller assembly includes end roller assemblies mounted at both ends of the connecting plate, intermediate roller assembly one mounted on both sides of the power assembly, and intermediate roller assembly two mounted inside the end roller assembly.

[0013] In the above technical solution, the stepped roller assemblies form a multi-segment support structure. The end rollers withstand the impact of the conveyor belt reversing direction, the first intermediate roller assembly provides main support near the power source, and the second intermediate roller assembly further enhances the rigidity of the belt's center. This segmented layout can adapt to the tension changes caused by the high-speed operation of the conveyor belt and reduce local deformation through multi-point support. It is particularly suitable for conveying long-sized soft-pack battery cells, preventing belt sagging that could lead to cell displacement. This ensures smooth conveying while dispersing mechanical stress, extending the equipment's service life.

[0014] Furthermore, the clamping device includes a clamping bracket and a clamping cylinder assembly and a lower pressing base plate mounted on the clamping bracket. The end of the clamping cylinder assembly is connected to the lower pressing assembly, and a shaping lower pad is mounted on the lower pressing base plate. The lower pressing assembly and the shaping lower pad are correspondingly arranged in the vertical direction.

[0015] In the above technical solution, the vertical alignment design of the pressing cylinder-driven pressing component and the shaping pad provides uniform and controllable pressing force, ensuring that the force is balanced and precisely controlled during the cell shaping process; the pressing force is precisely regulated by the pneumatic system, which can adapt to the shaping pressure requirements of cells of different thicknesses; this structure avoids the problem of cell skewing caused by traditional unilateral pressure application, ensures uniform force between electrode stacking layers, and improves the consistency of cell compaction density.

[0016] Furthermore, the pressing assembly includes a central transmission assembly connected to the pressing cylinder assembly. The bottom of the central transmission assembly is elastically connected to a guide post mounting plate. The bottom of the guide post mounting plate is connected to a shaping upper pad. A pressing guide assembly and a limit switch assembly are also connected to one side of the guide post mounting plate.

[0017] In the above technical solution, the guide post mounting plate is elastically connected to the central transmission assembly, providing flexible buffering during the pressing process to prevent rigid impact caused by cell thickness tolerance; the linear bearing of the pressing guide assembly ensures the verticality of the pressing trajectory, and the limit switch assembly precisely limits the upper and lower limits of the pressing stroke; the dual protection mechanism not only avoids overvoltage damage to the internal structure of the cell, but also provides real-time feedback on the pressing status and triggers an emergency stop in case of abnormality, greatly improving equipment safety and process controllability.

[0018] Furthermore, the clamping cylinder assembly includes a clamping cylinder and a cylinder connector one; the central transmission assembly includes a cylinder connector two, a sensor top plate, a sensor guide post, a sensor, and a sensor base plate connected sequentially from top to bottom, the sensor base plate being connected to the guide post mounting plate via the sensor guide post and a spring; the clamping guide assembly includes a downward pressure guide post connected to the guide post mounting plate via a flange seat and a first linear bearing sleeved on the downward pressure guide post, the first linear bearing being fixedly mounted on the clamping upper bracket, and sensor plate one and sensor plate two being connected above the downward pressure guide post; the limit switch assembly includes a limit switch mounting base mounted on the clamping bracket, and limit switch one and limit switch two mounted on the limit switch mounting base.

[0019] The sensor is a pressure sensor used to control the force pressing the battery cell and prevent overvoltage. Sensor 1 and Sensor 2 are stop plates, and the limit switches act as limit switches for the pressing cylinder. Limit switch 1 controls the lower limit of the pressing cylinder, and limit switch 2 controls the upper limit. Sensor 1 and Sensor 2 move up and down with the pressing cylinder, respectively triggering limit switches 1 and 2, thus controlling the lifting and lowering limits of the pressing cylinder.

[0020] In the above technical solution, the dynamic compensation system composed of the sensor and the spring can monitor the pressing status in real time and automatically compensate for deformation error; the combination of the sensing plate and the limit switch assembly controls the lifting limit of the pressing cylinder to achieve double protection and improve the pressing accuracy; the layered guide structure eliminates the influence of lateral load on the pressing accuracy through the multi-stage cooperation of the cylinder connector, guide column and linear bearing, and ensures the high-precision execution of the pressing action.

[0021] Furthermore, the clamping bracket includes an upper clamping bracket and a lower clamping bracket. The clamping cylinder is installed above the upper clamping bracket, and its extended end extends to the lower part of the upper clamping bracket and connects to the cylinder connector. The first linear bearing passes through the upper clamping bracket. The lower pressing base plate is installed on the lower clamping bracket.

[0022] In the above technical solution, the split clamping bracket separates the upper clamping bracket and the lower clamping bracket. The upper bracket carries the cylinder power unit, and the lower bracket fixes the shaping lower pad. The two form a stable frame through the downward pressure guide column, which takes into account both structural rigidity and assembly convenience. The design of the linear bearing running through the upper bracket not only ensures the smooth movement of the downward pressure guide column, but also disperses the lateral torque of the guide column through the bracket body, which enhances the clamping and guiding accuracy and reduces the risk of mechanical wear.

[0023] Furthermore, the positioning device includes a mounting bracket, a cell-end positioning device, and a cell-side positioning device; the cell-end positioning device includes a positioning guide component and a positioning drive component connected to the mounting bracket, the ends of the positioning guide component and the positioning drive component facing the cell are both connected to a cell-end push plate, pushing the cell-end push plate to adjust its position to position the end face of the cell; the cell-side positioning device includes a lateral movement component, a lifting component, and a side baffle component; the moving end of the lifting component is connected to the lateral movement component, and the moving end of the lateral movement component is connected to the side baffle component, driving the side baffle component to adjust its position to position the side of the cell.

[0024] In the above technical solution, the cell-end positioning device completes axial positioning by driving the push plate with a cylinder, and the side positioning device adopts a lifting and lateral movement composite motion mechanism to achieve envelope positioning of the cell in three-dimensional space, which significantly improves the positioning reliability of complex-shaped cells.

[0025] Furthermore, the positioning and guiding assembly includes a guide mounting plate, a positioning guide rod connected to the guide mounting plate, and a second linear bearing sleeved on the outside of the positioning guide rod. The guide mounting plate is mounted on the mounting bracket. The positioning drive assembly includes a positioning cylinder and a cylinder mounting plate connecting the positioning cylinder and the mounting bracket. The extended end of the positioning cylinder is connected to the cell end push plate. The lifting assembly includes a lifting cylinder, a positioning connecting plate, and a cylinder upper mounting seat for mounting the lifting cylinder. The cylinder upper mounting seat is connected to the positioning connecting plate via a third linear bearing. The extended end of the lifting cylinder is sequentially connected to a lifting cylinder connector, a fixing block, a second buffer seat, a second buffer valve, and a buffer screw. The second buffer valve is a buffer device installed on the second buffer seat, which buffers the lifting of the side baffle assembly to prevent accidental damage to the cell. The second buffer valve is placed in the buffer... Directly below the screw, the height of the side baffle assembly can be adjusted by adjusting the height of the buffer screw to accommodate different battery cell heights. The transverse movement assembly includes a transverse movement cylinder and a cylinder seat for mounting the transverse movement cylinder. The extended end of the transverse movement cylinder is sequentially connected to cylinder connector three and a guide rail. A slider is slidably connected to the guide rail, and the slider is connected to a slide rail connecting plate. A buffer seat one and a buffer valve one are also connected to the slide rail connecting plate. The cylinder mounting seat, positioning connecting plate, and slide rail connecting plate are arranged sequentially from top to bottom and connected by positioning guide posts. The bottom end of the buffer screw is connected to the slide rail connecting plate. The side baffle assembly includes a baffle one connected to the side of the positioning connecting plate, a baffle two connected to the baffle one and extending to both sides along the conveying direction, and a baffle three perpendicularly connected to the baffle two and arranged at equal intervals along the direction of the baffle two.

[0026] In the above technical solution, the synergistic effect of the buffer component and the linear bearing effectively absorbs the positioning impact and prevents scratches on the surface of the battery cell. The guide rail slider mechanism, in conjunction with the linear bearing, ensures the accuracy of the linear motion trajectory of the side baffle. The three-stage guide column penetrates the cylinder seat, the connecting plate and the slide rail connecting plate to form a three-dimensional guide network, eliminating the cumulative error in multi-degree-of-freedom motion and ensuring high repeatability of longitudinal positioning.

[0027] Furthermore, the clamping device is provided in several groups, arranged in parallel along the direction of cell conveying.

[0028] In the above technical solution, multiple sets of clamping devices can be arranged side by side along the production line to form parallel processing workstations. Each set of clamping devices is independently controlled, supporting the simultaneous shaping of multiple battery cells. The modular design allows for flexible increases or decreases in the number of pressure-reducing stations according to production capacity requirements, thereby improving the single-machine capacity. In addition, when multiple stations work together, pressure parameters can be set differently to meet special process requirements such as gradient compaction, significantly enhancing the equipment's process adaptability.

[0029] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0030] This invention constructs an intelligent operation system for the entire process of battery cell shaping through the three-dimensional collaborative design of a conveying device, a pressing device, and a positioning device. The overall structure is simple and occupies a small area, and can be compatible with battery cells of different sizes. At the same time, it can improve the flatness of the battery cells, eliminate separator wrinkles, and ensure that the battery cell thickness meets the requirements of the battery cell casing process, preventing damage to the battery cells during casing. It also helps to reduce the internal resistance of the battery, improve the process performance of the battery, and help to improve production efficiency, reduce the labor intensity of personnel, and realize automated production.
