[0043] Reference Figure 1 and Figure 2 This application provides a battery cell handling device, which includes:

[0044] Base 1;

[0045] Robotic arm 10, which is connected to base 1 and has a rotating end 241 and a moving end 121;

[0046] The gripping component 2 is connected to the rotating end 241, and the recycling platform 3 is connected to the moving end 121.

[0047] In the above embodiment, the base 1 serves as the fundamental structure of the entire cell handling device, providing a stable mounting platform for components such as the gripping assembly 2 and the recycling platform 3. During the cell production process of the winding equipment, the cell handling device needs to operate continuously to complete the sorting and conveying tasks of the cells. The base 1 can withstand the forces generated by each component during operation, ensuring the stability of the overall structure of the cell handling device and preventing the accuracy of cell gripping, handling, and sorting from being affected by shaking or deformation of the cell handling device.

[0048] See Figure 1The robotic arm 10 integrates rotation and linear motion functions. The gripping component 2 is connected to the rotating end 241 of the robotic arm 10, which facilitates the rotation and movement of the gripping component 2 in the horizontal or vertical plane, thereby adapting to the gripping needs of the battery cells in different positions. The recycling platform 3 is connected to the moving end 121. The recycling platform 3 is driven to move by a cylinder, linear motor or synchronous belt, which can realize the rapid recycling and precise sorting of the battery cells.

[0049] In the above embodiments, the gripping component 2 directly contacts the battery cell and is used to perform the actions of gripping, holding, and releasing the battery cell. By adjusting the gripping position and angle of the gripping component 2 through the rotating end 241 of the robotic arm 10, the gripping component 2 can adapt to the gripping needs of battery cells of different sizes (such as square or cylindrical battery cells) or battery cells of different postures (such as tilted or stacked battery cells), and also reduces the overall range of movement of the robotic arm 10, which can shorten the time cycle of a single gripping operation.

[0050] The gripping component 2 can grip battery cells of two types, such as first-type cells being qualified and second-type cells being unqualified. Qualified cells gripped by the gripping component 2 can be conveyed to subsequent workstations via a feeding conveyor line for further processing and production. Unqualified cells gripped by the gripping component 2 can be transferred to the recycling platform 3. The moving end of the robotic arm 10 drives the recycling platform 3 to move horizontally or vertically, thereby placing the unqualified cells into the recycling area. Furthermore, the stroke of the moving end is adjustable to allow the recycling platform 3 to adapt to recycling areas of different lengths or heights, thus improving the battery cell handling device's ability to process different types of battery cells.

[0051] In one embodiment, the base 1 may have a multi-axis movable transfer robot and a linearly moving moving plate. The gripping component 2 is connected to the transfer robot, which facilitates the gripping component 2 to quickly and accurately grip the battery cells. The recycling platform 3 is connected to the moving plate, which enables the battery cells that need to be recycled to be transferred to the recycling area in a timely manner.

[0052] This application embodiment integrates rotation and movement functions into a single robotic arm, reducing the superposition design of traditional rotating and linear mechanisms and simplifying the structure of the battery cell handling device. Moreover, the flexible movement of the robotic arm enables the gripping component 2 to quickly grasp the battery cell and promptly transfer the battery cell to the recycling platform 3 when it needs to be recycled, improving the compatibility of battery cell handling, ensuring the stability of battery cell handling, and improving battery cell production efficiency.

[0053] In addition, the fewer internal wirings of the robotic arm 10 reduce its failure rate and ensure its operational stability.

[0054] In some embodiments, see Figure 1The robotic arm 10 includes a movable member 12 and a multi-degree-of-freedom movable member 24. The movable member 12 is movably connected to the base 1 and forms a movable end 121 at the end away from the base 1. The multi-degree-of-freedom movable member 24 is connected to the movable member 12 and forms a rotating end 241 at the end away from the movable member 12.

[0055] In the above embodiment, the movable component 12 is movably connected to the base 1. For example, the base 1 is provided with a slide rail, and the movable component 12 slides in cooperation with the slide rail, which can ensure the stability of the linear movement of the recycling platform 3 and achieve accurate recycling of the battery cells. The multi-degree-of-freedom rotation and movement of the multi-degree-of-freedom movable component 24 facilitates the adjustment of the posture of the gripping component 2 in three-dimensional space, thereby adapting to the gripping of different battery cells, realizing seamless connection of battery cell gripping, rotation and placement actions, shortening the operation cycle of a single gripping, and improving the efficiency of battery cell gripping.

[0056] In some embodiments, see Figure 1 and Figure 2 The gripping component 2 includes a clamping drive 21 and a clamping member 20. The clamping drive 21 is connected to the rotating end 241. The clamping member 20 includes a first clamping member 22 and a second clamping member 23 that are relatively spaced apart from each other on the clamping drive 21. The clamping drive 21 can drive the first clamping member 22 and the second clamping member 23 to move closer to each other and further away from each other, so as to form a cell clamping space between the first clamping member 22 and the second clamping member 23.

[0057] See Figure 1 The gripping component 2 is used to grip the wound battery cells conveyed from the battery cell conveyor line for subsequent sorting and conveying operations. The accurate gripping by the gripping component 2 ensures that the battery cells will not fall or shift during handling, guaranteeing battery cell quality and the continuity of the production process. The clamping drive component 21 is movably connected to the base 1, providing power for the mutual approach and distance of the first clamping component 22 and the second clamping component 23. During battery cell handling, the clamping drive component 21 can precisely control the relative approach or backward movement of the first clamping component 22 and the second clamping component 23 according to the instructions of the control system, thereby achieving reliable clamping and releasing operations on the battery cells.

[0058] Furthermore, the cell clamping space between the first clamping member 22 and the second clamping member 23 can be flexibly adjusted according to the size of the cell, adapting to the gripping of cells of different specifications, thus improving the versatility and flexibility of the cell handling device. When the first clamping member 22 and the second clamping member 23 are close to each other, they can firmly clamp the cell within the cell clamping space, preventing the cell from sliding or falling off during handling, thus ensuring the safety and reliability of cell handling.

[0059] See Figure 1The clamping member 20 of the gripping component 2 has a feeding position for clamping qualified battery cells. When the clamping member is in the feeding position, the clamping member moves to be opposite to the feeding box on the feeding conveyor line 400, so that the gripping component 2 can transport the qualified battery cells to the empty box on the feeding conveyor line.

[0060] In the above embodiment, the recycling platform 3 is used to receive the defective battery cells gripped by the gripping component 2. During the battery cell sorting process, when a defective battery cell is detected, the gripping component 2 transports the defective battery cell to the top of the recycling platform 3. Since the clamping member has a recycling position that is vertically opposite to the recycling platform 3, the clamping member releases the battery cell, allowing the defective battery cell to fall accurately onto the recycling platform 3. This achieves centralized recycling of defective battery cells, preventing defective battery cells from being mixed with qualified battery cells and ensuring the quality of the battery cell products.

[0061] In another embodiment, the gripping component 2 can grip the battery cell using a suction cup. For lightweight battery cells, a single suction cup can be used to hold the cell in place before transferring it, simplifying the structure of the battery cell handling device. For heavy battery cells, two or more suction cups can be used to hold the cell in place before transferring it, ensuring the stability of the cell transfer.

[0062] In some embodiments, see Figure 2 The first clamping member 22 includes a first hook 221, and the second clamping member 23 includes a second hook 231. The first hook 221 and the second hook 231 are arranged at a distance from each other on the clamping drive member 21.

[0063] In the above embodiments, the curved hook design in the first claw 221 can better fit the edge or specific part of the battery cell. When gripping the battery cell, the claw of the first claw 221 can penetrate deep below the edge of the battery cell or be embedded in the groove or other structures of the battery cell. The hook action provides a stable gripping force, effectively preventing the battery cell from slipping during transportation and ensuring the reliability of the gripping. The second claw 231 cooperates with the first claw 221. Driven by the clamping drive 21, the second claw 231 and the first claw 221 move closer to each other to jointly clamp the battery cell, making the gripping force more evenly distributed on both sides of the battery cell, further improving the stability and reliability of the gripping.

[0064] In some embodiments, see Figure 2 The first hook 221 includes a first connecting section 2211 and a first pressing section 2212 that are bent. The first clamping member 22 includes a first driving member 222 and a first pressing block 223. The first pressing block 223 is movably connected to the first connecting section 2211 through the first driving member 222, and a first clamping gap is formed between the first pressing block 223 and the first pressing section 2212.

[0065] The second hook 231 includes a bent second connecting section 2311 and a second pressing section 2312. The second clamping member 23 includes a second driving member and a second pressing block. The second pressing block is movably connected to the second connecting section 2311 through the second driving member, and a second clamping gap is formed between the second pressing block and the second pressing section 2312.

[0066] In the above embodiments, the first driving member 222 and the second driving member can be a cylinder, an electric cylinder or a linear motor, etc. The structure of the second clamping member 23 can be the same as the structure of the first clamping member 22 and symmetrically arranged to ensure the stability of the battery cell clamping.

[0067] In the structure of the first clamping member 22, the first connecting section 2211 can securely connect the first claw 221 to the clamping drive member 21, and the first pressing section 2212 directly contacts the battery cell and applies a pressing force to the battery cell to ensure that a uniform and sufficient pressing force can be provided when gripping the battery cell, preventing the battery cell from slipping during transportation. The bending arrangement of the first claw 221 allows the first pressing section 2212 to press the battery cell at a suitable angle, improving the stability and reliability of gripping.

[0068] See Figure 2 The first driving member 222 provides power for the movement of the first pressing block 223, enabling the first pressing block 223 to move relative to the first connecting section 2211. The first driving member 222 can precisely control the movement stroke and force of the first pressing block 223, thereby achieving flexible adjustment of the size of the first clamping gap. Depending on the specifications and materials of the battery cells, the first driving member 222 can adjust the distance between the first pressing block 223 and the first clamping section 2212 to provide appropriate clamping force, avoiding damage to the battery cells due to excessive clamping force or ineffective fixation of the battery cells due to insufficient clamping force.

[0069] See Figure 2 The second clamping gap formed by the second clamping member 23 cooperates with the first clamping gap to clamp the battery cell. By adjusting the position of the second pressure block, the size of the second clamping gap can be precisely controlled to ensure that the battery cell is firmly fixed between the two clamping gaps.

[0070] In some embodiments, see Figure 3 The recycling platform 3 includes a connector 31, a lifting member 32, and a support member 33. One end of the connector 31 is connected to the base 1, and the support member 33 is movably connected to the other end of the connector 31 through the lifting member 32.

[0071] In the above embodiments, the carrier 33 can be a belt conveyor or a movable platform. Since both the gripping component 2 and the recycling platform 3 can be installed on the movable component 12 of the movable plate structure, when the battery cell needs to be transferred to the recycling platform 3, the lifting component 32 such as the cylinder on the recycling platform 3 needs to lift the carrier 33 so that the battery cell gripped by the gripping component 2 can fall onto the carrier 33 on the recycling platform 3, thus avoiding the battery cell from shifting or slipping during transportation or processing, and ensuring the safety and integrity of the battery cell recycling.

[0072] In some embodiments, see Figure 3 The carrier 33 includes a pulley 331 and a conveyor belt 332, with the conveyor belt 332 wrapped around the pulley 331.

[0073] In the above embodiments, the conveyor belt 332 carries and transports the battery cells through cyclic motion. By rotating the conveyor belt 332 on the pulley 331, for example by driving the pulley 331 to rotate through a motor, the conveyor belt 332 can be rotated automatically, thereby improving the efficiency of battery cell transfer.

[0074] This application provides a winding machine, which includes the aforementioned cell handling device 100.

[0075] In the above embodiment, the battery cell handling device 100 of the winding machine connects the robotic arm 10 to the base 1 and has a rotating end 241 and a moving end 121; the gripping component 2 is connected to the rotating end 241, and the recycling platform 3 is connected to the moving end 121. By integrating rotation and movement functions into a single robotic arm, the superimposed design of the rotation mechanism and linear mechanism of the traditional device is reduced, simplifying the structure of the battery cell handling device; moreover, the flexible movement of the robotic arm can support the gripping component 2 to quickly grip the battery cell, and promptly transfer the battery cell to the recycling platform 3 when it needs to be recycled, improving the compatibility of battery cell handling, ensuring the stability of battery cell handling, and improving battery cell production efficiency.

[0076] In some embodiments, see Figures 4 to 6 The winding machine includes a cell conveyor line 200 and a sorting conveyor line 300;

[0077] The gripping component 2 of the battery cell handling device 100 can grip battery cells from the battery cell conveyor line 200, and the recycling platform 3 can be positioned opposite the sorting conveyor line 300 so that the battery cells can be transferred between the recycling platform 3 and the sorting conveyor line 300.

[0078] In the above embodiments, the cell conveyor line 200 can stably and continuously transport cells from the previous production stage (such as the cell manufacturing process) to the gripping position of the cell handling device 100, avoiding production stoppages caused by cell supply interruptions and improving the overall efficiency of cell production. The sorting conveyor line 300 can classify and sort the cells. According to the different grades of unqualified cells, the sorting conveyor line 300 can guide the cells to different branch lines or positions, achieving accurate sorting and recycling of cells.

[0079] In one embodiment, the cell conveying line 200 and the sorting conveying line 300 can be arranged perpendicularly to each other and staggered vertically, making full use of the space in the production site, enabling the cell conveying line 200 and the sorting conveying line 300 to operate efficiently in a limited space, and improving the structural compactness of the winding machine.

[0080] See Figure 5 The battery cell handling device 100 can accurately pick up battery cells from the battery cell conveyor line 200 and transport them to the recycling platform 3 or other designated locations. The battery cell handling device 100 can adapt to battery cells of different specifications and shapes, ensuring that the battery cells are not damaged during the handling process, thereby improving the quality of the battery cells and production efficiency.

[0081] In some embodiments, see Figure 6 The sorting and conveying line 300 includes multiple stacked conveying layers 301, and the recycling platform 3 can be opposite any one of the conveying layers 301.

[0082] In the above embodiments, since the recycling platform 3 carries substandard battery cells of different grades, operators can classify and process them according to their substandard grade. For example, some substandard battery cells that can be easily repaired and reused can be classified and repaired separately; while substandard battery cells that cannot be repaired or whose repair costs are too high can be scrapped in accordance with environmental protection requirements, thereby improving the processing efficiency and resource utilization of substandard battery cells and reducing production costs.

[0083] The sorting conveyor line 300 can transport different grades of unqualified battery cells separately. The recycling platform 3 can be aligned with any conveyor layer 301 to achieve precise docking of different grades of unqualified battery cells on the recycling platform 3 with the corresponding conveyor layer 301. The battery cells on the recycling platform 3 can then be transported to the corresponding conveyor layer 301 for further processing.

[0084] In some embodiments, see Figure 5 and Figure 6 The winding machine also includes a feeding conveyor line 400, and the gripping component 2 is able to transfer the battery cells into the material box on the feeding conveyor line 400.

[0085] After the battery cells undergo a series of processes such as winding and testing, qualified cells need to be transferred from the production station to subsequent packaging, storage, or transportation stages. The feeding conveyor line 400 can continuously and stably transport qualified cells from the production area to the designated location, forming a complete automated production line and improving production efficiency and continuity.

[0086] In the above embodiments, the gripping component 2 can accurately identify and grip qualified battery cells and place them precisely into the material box on the unloading conveyor line 400, ensuring that qualified battery cells are processed correctly, avoiding problems such as misplacement or omission of battery cells, and improving the accuracy and reliability of production.

[0087] In some embodiments, see Figure 5 and Figure 6 The feeding conveyor line 400 includes a material box transfer line 401 and a material box conveyor line 402. The material box transfer line 401 can transfer the qualified battery cells grabbed by the gripping component 2 to the material box conveyor line 402.

[0088] In the above embodiment, the material box conveyor line 402 is used to convey material boxes 4023. The material box transfer line 401 and the material box conveyor line 402 can be arranged perpendicular to each other to reduce interference between the conveyor lines and improve space utilization. The material box transfer line 401 acts as a bridge between the gripping component 2 and the material box conveyor line 402, ensuring that qualified battery cells are smoothly transferred from the gripping component 2 to the material box conveyor line 402, guaranteeing the stability and accuracy of the battery cells during the transfer process, thereby realizing the smooth flow of battery cells on the entire unloading conveyor line 400.

[0089] In some embodiments, see Figure 6 The material feeding conveyor line 400 includes a lifting conveyor line 403, the material box transfer line 401 includes a first material box transfer line 4011 and a second material box transfer line 4012 arranged at intervals above and below, and the material box conveyor line 402 includes a first material box conveyor line 4021 and a second material box conveyor line 4022 arranged at intervals above and below. The first material box transfer line 4011 and the first material box conveyor line 4021 are arranged opposite to each other, and the second material box transfer line 4012 and the second material box conveyor line 4022 are arranged opposite to each other.

[0090] The lifting conveyor line 403 is used to receive qualified battery cells gripped by the gripping component 2, and can switch between a first height position relative to the first material box transfer line 4011 and a second height position relative to the second material box transfer line 4012.

[0091] In the above embodiments, the cell conveying line 200 transports the cells to a set position. In one embodiment, if the cell is a qualified product, the cell handling device 100 transfers the cell to an empty material box on the lifting conveyor line 403. The first material box conveyor line 4021 is used to transport empty material boxes, which are transported from the first material box conveyor line 4021 along... Figure 6 The material is conveyed in the direction of the arrow above the first material box transfer line 4011 to the first material box transfer line 4011. The first material box transfer line 4011 conveys the empty material box to the belt conveyor 4031 on the lifting conveyor line 403. After the qualified battery cell is placed into the empty material box on the belt conveyor 4031 on the lifting conveyor line 403, the lifting conveyor line 403 moves along... Figure 6 The arrow next to the middle lifting conveyor line 403 moves upward, thereby driving the belt conveyor 4031 to connect with the second material box transfer line 4012.
