Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, specifically to a cell sorting device and cell processing equipment. Background Technology

[0002] Existing battery cell sorting devices generally use screw or chain drive structures. These mechanical transmission methods are prone to vibration during operation, leading to insufficient cell positioning accuracy and subsequent sorting misalignment. The production of high-energy-density batteries places higher demands on the sorting process, but the basic control system of traditional equipment is difficult to effectively suppress vibration interference, causing deviations in cell transmission and positioning, resulting in a persistently high missorting rate.

[0003] Furthermore, the separation mechanism between defective and qualified cells is not precise enough, often resulting in misplacement due to inconvenient adjustment of positioning components or inflexible synchronous belt control, affecting the continuous and stable operation of subsequent processing lines. Therefore, existing cell sorting devices are inadequate in handling the precise sorting of high-energy-density batteries, and are particularly unable to meet the new requirements of power battery manufacturers for sorting efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a battery cell sorting device and battery cell processing equipment, which solves the technical problems of insufficient positioning accuracy and high missorting rate of the existing battery cell sorting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a battery cell sorting device, including a battery cell sorting module, a defective battery cell unloading component, and a qualified battery cell transport module. The defective battery cell unloading component is used to transfer and collect the defective battery cells selected by the battery cell sorting module, and the qualified battery cell transport module is used to transport the qualified battery cells selected by the battery cell sorting module to a subsequent processing line. The battery cell sorting module includes a Y-axis motion module and a sorting synchronization component. The sorting synchronization component includes a base plate connected to the Y-axis motion module, and a sorting synchronization belt, a control motor, and a positioning component mounted on the base plate.

[0006] The transmission directions of the defective battery cell unloading assembly and the qualified battery cell transport module are both perpendicular to the movement direction of the Y-axis motion module, and the defective battery cell unloading assembly and the qualified battery cell transport module are respectively arranged on opposite sides of the Y-axis motion module. The sorting synchronous belt is used to transport and carry defective and qualified battery cells. The control motor is electrically connected to the sorting synchronous belt and is used to control the rotation direction of the sorting synchronous belt. The positioning assembly is arranged on opposite sides of the synchronous belt and along the movement direction of the sorting synchronous belt, and the positioning assembly is used to limit the displacement of defective and qualified battery cells.

[0007] In one possible implementation, the positioning component includes two positioning mounting plates connected to the sorting timing belt, and two sorting positioning plates, which are respectively mounted on the two positioning mounting plates.

[0008] In one possible implementation, the positioning component further includes at least one adjusting member, one of the sorting positioning plates being connected to the positioning mounting plate via the adjusting member, the adjusting member being used to adjust the spacing between the two sorting positioning plates.

[0009] In one possible implementation, the sorting synchronization component further includes a timing belt adapter plate, through which the sorting timing belt is mounted on the base plate.

[0010] In one possible implementation, the defective battery cell unloading assembly includes a feeding timing belt, a positioning adapter plate, two feeding positioning plates, and a blocking component. The two feeding positioning plates are respectively disposed on opposite sides of the feeding timing belt. The feeding positioning plates are connected to the feeding timing belt via the positioning adapter plate and are positioned along the movement direction of the feeding timing belt. The blocking component is connected to the two feeding positioning plates at both ends and is located at the end of the feeding timing belt away from the feeding direction. The blocking component is used to intercept and collect defective battery cells.

[0018] To solve the above-mentioned technical problems, this utility model provides a battery cell sorting device and a battery cell processing equipment. The technical solution and embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connection, detachable connection, or integral connection; for those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0021] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] In traditional battery cell sorting technologies, sorting devices using screw or chain drive structures suffer from insufficient positioning accuracy due to mechanical vibration, causing cell positional shifts during transport. Simultaneously, the lack of optimized sorting path design results in redundant robotic arm trajectories, significantly increasing the missorting rate. Furthermore, vibration interference affects the stability of sensor signals, leading to a decrease in the accuracy of matching sorting results with test data, thereby impacting sorting efficiency and equipment reliability.

[0023] If the above problems are not solved, sorting errors will lead to potential battery quality risks, increase the risks of subsequent processes, continuously deteriorate the stability of equipment operation, increase the failure rate and affect the continuity of production, fail to meet the technical requirements of flexible production and rapid model changeover for new form batteries, restrict the improvement of sorting accuracy and data traceability, and ultimately make it difficult for the equipment to adapt to the precision sorting requirements of high energy density batteries.

[0024] like Figures 1 to 4 As shown, this utility model provides a battery cell sorting device, including a battery cell sorting module 1, a defective battery cell unloading assembly 2, and a qualified battery cell transport module 3. The defective battery cell unloading assembly 2 is used to transfer and collect the defective battery cells selected by the battery cell sorting module 1, and the qualified battery cell transport module 3 is used to transport the qualified battery cells selected by the battery cell sorting module 1 to the subsequent processing line. The transmission directions of both the defective battery cell unloading assembly 2 and the qualified battery cell transport module 3 are perpendicular to the movement direction of the Y-axis motion module 11, and the defective battery cell unloading assembly 2 and the qualified battery cell transport module 3 are respectively arranged on opposite sides of the Y-axis motion module 11.

[0025] The battery cell sorting module 1 includes a Y-axis motion module 11 and a sorting synchronization component. The sorting synchronization component includes a base plate 16 connected to the Y-axis motion module 11, and a sorting synchronization belt 12, a control motor 13, and a positioning component mounted on the base plate 16. The sorting synchronization belt 12 is used to transport and carry defective and qualified battery cells. The control motor 13 is electrically connected to the sorting synchronization belt 12 and is used to control the rotation direction of the sorting synchronization belt 12. The positioning component is located on opposite sides of the synchronization belt and is arranged along the movement direction of the sorting synchronization belt 12. The positioning component is used to limit the displacement of defective and qualified battery cells.

[0026] Among them, the Y-axis motion module 11 refers to a device that provides linear motion in the Y-axis direction. It can be implemented by a linear module driven by a linear motor or a ball screw in conjunction with a guide rail, such as a linear motor module or a ball screw system driven by a servo motor. Its main purpose is to realize the movement of the battery cell in the Y-axis direction.

[0027] The sorting synchronous belt 12 refers to the conveyor belt used to transport battery cells. It can be made of rubber synchronous belt or metal chain, such as toothed belt or chain conveyor belt. It is mainly used to transport defective battery cells and qualified battery cells.

[0028] The control motor 13 refers to the drive device that controls the direction of rotation of the synchronous belt. It can be implemented by a servo motor or a stepper motor, such as an AC servo motor or a DC brushless motor. Its main purpose is to control the direction of rotation of the sorting synchronous belt 12.

[0029] Positioning components refer to devices that limit the displacement of battery cells. They can be implemented using fixed blocks, adjustable limit pins, or pneumatic clamping devices, such as spring-loaded limit pins or electromagnetic clamps. Their main purpose is to limit the displacement of defective and qualified battery cells.

[0030] This application solves the problems of insufficient positioning accuracy, high missorting rate, and positioning deviation caused by vibration of traditional mechanical transmission during the battery cell sorting process by using a Y-axis motion module 11 to provide stable linear motion, a sorting synchronous belt 12 to realize battery cell transportation, a control motor 13 to adjust the rotation direction, a positioning component to limit displacement, and a coordinated setting of orthogonal layout of transmission direction.

[0031] See Figure 3 Furthermore, the positioning assembly includes two positioning mounting plates 15 connected to the sorting timing belt 12, and two sorting positioning plates 14, which are respectively mounted on the two positioning mounting plates 15.

[0032] Among them, the positioning mounting plate 15 is a key component used to construct the basic support structure of the positioning component. It can be made of rigid metal sheet or high-strength engineering plastic, with the aim of providing a stable installation benchmark to ensure the overall rigidity of the component.

[0033] The sorting and positioning plate 14 is a functional component that directly acts on the lateral limit of the battery cell. It can be made of wear-resistant rubber or metal baffles. Its purpose is to form a constraint on both sides of the battery cell to prevent displacement.

[0034] Specifically, the direct connection between the positioning mounting plate 15 and the sorting synchronous belt 12 ensures that the entire positioning assembly can move in strict synchronization with the synchronous belt, effectively avoiding relative displacement caused by insufficient connection rigidity, thereby isolating the transmission of vibration generated during the operation of the synchronous belt. Two sorting positioning plates 14 are respectively installed on the positioning mounting plate 15, allowing the limiting components to be precisely positioned independently of the base support, forming a reliable constraint on the battery cells in the direction of synchronous belt movement, preventing the battery cells from shifting.

[0035] Through the above-mentioned scheme, this application effectively enhances the positional stability during the cell sorting process, prevents cell positioning reference drift, reduces the sorting misplacement rate, and improves the reliability of equipment operation.

[0036] like Figure 3 As shown, the positioning assembly further includes at least one adjusting member 18, and a sorting positioning plate 14 is connected to the positioning mounting plate 15 through the adjusting member 18. The adjusting member 18 is used to adjust the distance between the two sorting positioning plates 14.

[0037] The adjusting element 18 refers to an adjustable connection mechanism, which can be implemented by bolts, slide rails or screw mechanisms. Its purpose is to provide an operable mechanism to dynamically adjust the distance between the two sorting and positioning plates 14, so as to adapt to the sorting requirements of different specifications of battery cells and avoid positioning deviation problems caused by size mismatch.

[0038] Specifically, the adjusting member 18 allows one sorting positioning plate 14 to be adjusted relative to the positioning mounting plate 15. When dealing with battery cells of different sizes, the operator can change the spacing between the two sorting positioning plates 14 by operating the adjusting member 18 to ensure that the battery cells are accurately positioned on the sorting synchronous belt 12. This adjustment process does not require disassembling the entire assembly. The connection between the adjusting member 18 and the positioning mounting plate 15 enables a rapid response while maintaining the structural stability of the positioning assembly, thus forming a complete spacing adjustment mechanism.

[0039] Through the above solution, this application significantly improves the adaptability of the equipment, reduces downtime during the changeover process, and ensures the precise positioning of the battery cells on the sorting synchronous belt 12, effectively solving the sorting adaptability problem caused by changes in battery cell size.

[0040] See Figure 3 Furthermore, the sorting synchronization component also includes a timing belt adapter plate 17, through which the sorting timing belt 12 is mounted on the base plate 16.

[0041] The synchronous belt adapter plate 17 is a structural component used to indirectly connect the sorting synchronous belt 12 and the base plate 16. It can be made of sheet metal or composite material and is designed to provide cushioning and enhance installation rigidity. This structural component can accommodate minor deformations of the base plate 16 and disperse external vibration loads, avoiding stress concentration.

[0042] Specifically, the synchronous belt adapter plate 17 acts as an independent buffer, avoiding a direct rigid connection between the sorting synchronous belt 12 and the base plate 16. This allows the installation process to adapt to minor deformations of the base plate 16 and external vibration interference, preventing stress concentration and dynamic instability caused by direct installation. The adapter plate's structural design achieves indirect fixation. Utilizing its rigid support and vibration absorption characteristics, it effectively isolates the mechanical impact transmitted by the Y-axis motion module 11, ensuring the sorting synchronous belt 12 maintains stable operation during operation. This, in turn, maintains the precise position of the battery cells on the synchronous belt, reduces displacement errors caused by vibration, and provides a stable foundation for subsequent battery cell delivery to the positioning components.

[0043] Through the above solution, this application effectively reduces displacement error caused by vibration, improves cell positioning accuracy, reduces sorting misplacement rate, and thus enhances the stability and reliability of the overall sorting device.

[0044] like Figure 4 As shown, the defective cell unloading assembly 2 further includes a unloading timing belt 21, a positioning adapter plate 23, two unloading positioning plates 22, and a blocking member 24. The two unloading positioning plates 22 are respectively disposed on opposite sides of the unloading timing belt 21. The unloading positioning plates 22 are connected to the unloading timing belt 21 through the positioning adapter plate 23, and the unloading positioning plates 22 are arranged along the movement direction of the unloading timing belt 21. The two ends of the blocking member 24 are respectively connected to the two unloading positioning plates 22, and the blocking member 24 is located at the end of the unloading timing belt 21 away from the unloading direction. The blocking member 24 is used to intercept and collect defective cells.

[0045] Among them, the feeding synchronous belt 21 refers to a continuous belt conveyor mechanism used to transport defective battery cells. It can be implemented by using a rubber synchronous belt or a polyurethane synchronous belt. Its purpose is to provide a smooth battery cell transport path and adapt to the transfer needs of battery cells of different sizes.

[0046] The two feeding positioning plates 22 can be understood as limiting structures extending along the transmission direction. They can be implemented using straight metal plates or engineering plastic plates with curved edges. The purpose is to form a continuous lateral constraint channel to prevent the battery cells from shifting laterally during transmission.

[0047] The barrier 24 specifically refers to the interception component set at the end of the transmission. It can be implemented by means of a metal rod, an elastic buffer baffle, or an adjustable height block. Its purpose is to accurately block the battery cell from continuing to move and ensure reliable storage.

[0048] Specifically, two feeding positioning plates 22 are symmetrically arranged on opposite sides along the movement direction of the feeding synchronous belt 21, forming a stable lateral limiting channel. This ensures that the battery cells are continuously constrained throughout the transmission process, effectively suppressing lateral displacement caused by equipment vibration or motion inertia. The barrier 24 is rigidly connected to the two feeding positioning plates 22 at both ends, forming a closed frame structure. Its position is precisely set at the end of the feeding synchronous belt 21 away from the feeding direction. When the battery cells move to this position with the synchronous belt, they are reliably intercepted, preventing them from slipping off the conveyor belt due to inertia and causing them to scatter or accumulate chaotically. This achieves centralized collection of defective battery cells.

[0049] This utility model also provides a battery cell processing equipment, including the above-mentioned battery cell sorting device.

[0050] The above description is merely a preferred embodiment of the present utility model, and the specific embodiments described above are not intended to limit the present utility model. Various modifications and variations can be made within the scope of the technical concept of the present utility model. All refinements, modifications, or equivalent substitutions made by those skilled in the art based on the above description are within the scope of protection of the present utility model.
