Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a sheet positioning device and a battery manufacturing system. Background Art

[0002] Battery cells are widely used in electronic devices, such as mobile phones, laptop computers, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, electric tools, and energy storage systems, etc. Battery cells can include nickel-cadmium battery cells, nickel-hydrogen battery cells, lithium-ion battery cells, sodium-ion battery cells, and secondary alkaline zinc-manganese battery cells, etc.

[0003] At present, the market demand for battery monomers is gradually increasing, and people have put forward higher requirements on the production efficiency of battery monomers. Therefore, how to improve the production efficiency of battery monomers is also one of the research issues in this field. Utility Model Content

[0004] In view of the above problems, the present application provides a sheet positioning device and a battery manufacturing system, which can improve the sheet positioning accuracy and positioning efficiency, and improve the production efficiency of battery cells.

[0005] In the first aspect, the present application provides a sheet positioning device, including a workbench, a first limit block, a second limit block, a first pushing device and a second pushing device. The workbench is used to support the sheet, the first limit block is arranged on one side of the workbench along a first direction, and the second limit block is arranged on one side of the workbench along a second direction, and the second direction intersects with the first direction. The first pushing device is used to push the sheet to move along the first direction. The second pushing device is used to push the sheet to move along the second direction. Among them, the first pushing device and the second pushing device can push the sheet to abut against the first limit block and the second limit block.

[0006] In the technical solution of the embodiment of the present application, the workbench not only provides stable support for the sheet material, but also ensures that the pushing device can work on a flat and stable surface, thereby improving the stability of the entire positioning process. Therefore, when pushing the sheet material, no unexpected displacement or vibration will occur, which improves the accuracy of controlling the position of the sheet material. The first pushing device and the second pushing device work together to push the sheet material in different directions (first direction and second direction) respectively. This design allows multi-dimensional adjustment and control of the sheet material to ensure that it can be accurately aligned with the limit block. By accurately controlling the position of the sheet material in two directions, high-precision positioning of the sheet material can be achieved. In summary, the design of the sheet material positioning device makes full use of the stability of the workbench and the precise control ability of the pushing device, ensuring that the sheet material is quickly and accurately positioned, which can improve production efficiency while ensuring product quality.

[0007] In some embodiments, the first pushing device includes a first pushing block and a first pushing motor, and the first pushing block is arranged opposite to the first limit block and is respectively arranged on both sides of the sheet along the first direction. The first pushing motor is connected to the first pushing block, and the first pushing motor is used to push the first pushing block to move along the first direction. In the above technical solution, the first pushing motor can provide continuous and uniform thrust, and the first pushing block will not suddenly accelerate or decelerate during the movement, thereby ensuring a smooth moving trajectory. This smoothness can improve the accuracy of controlling the position of the sheet and the control efficiency of the sheet positioning.

[0008] In some embodiments, the sheet positioning device further comprises a base, the number of workbenches is N, the N workbenches are spaced apart on the base, the number of first push blocks is N, and the first push device comprises a first connecting block. The N first push blocks are respectively connected to the first connecting blocks, and the first connecting blocks are connected to the first push motor.

[0009] In the above structure, by setting the base, the number of workbenches is increased, and the sheet positioning device can position multiple sheets at the same time, thereby improving the efficiency of sheet positioning. In addition, by positioning multiple sheets at the same time, the production cycle can be shortened, thereby improving the overall production efficiency of the battery cell.

[0010] In some embodiments, the first pushing motor and the first connecting block are respectively arranged on opposite sides of the base, and the base is provided with a first sliding groove penetrating along the thickness direction of the base. One end of the first pushing motor passes through the first sliding groove and is connected to the first connecting block.

[0011] In the above technical solution, the first push motor and the first connecting block are respectively arranged on both sides of the base, the first connecting block is connected to the workbench, and the workbench and the first push motor can be respectively arranged on both sides of the base, so as to facilitate observation of the push of the first connecting block, and the operator or maintenance personnel can more easily see the movement of the first connecting block and the first push block and the interaction with other components; at the same time, the rationality of space utilization is improved, making the overall structure more compact and efficient. In some embodiments, a first slide rail extending along a first direction is provided on the base, and a first groove cooperating with the first slide rail is provided on the first push block, and the first slide rail is slidably connected with the first groove. In the above structure, by setting the first slide rail, the first push block can move on a predetermined path to ensure the accuracy and stability of the movement, and when the first groove is set, when the first push block moves along the first slide rail, the first groove ensures that it remains in the correct position and direction to prevent deviation or misoperation. The cooperation between the first slide rail and the first groove reduces friction and resistance, making the movement of the first push block smoother and easier to control. Therefore, the first push block can move more accurately and efficiently on the base, thereby improving the accuracy and efficiency of sheet positioning control. The above technical solution not only optimizes the positioning performance of the sheet positioning equipment, but also helps to improve production efficiency and product quality.

[0012] In some embodiments, the surface of one side of the workbench facing the sheet is concave to form an anti-sticking groove. By providing a concave anti-sticking groove, the risk of vacuum adsorption between the sheet and the workbench surface is reduced, and air is allowed to flow in the anti-sticking groove, thereby eliminating or reducing the vacuum adsorption force. When the sheet is no longer hindered by vacuum adsorption, it can move more smoothly on the workbench. This not only speeds up the movement of the sheet, but also reduces the additional operating steps caused by adsorption and release. Since the anti-sticking groove reduces the interference of vacuum adsorption, the sheet can be moved to a predetermined position more easily, thereby improving the accuracy of the positioning of the sheet, thereby improving the product quality and production efficiency of the battery cell.

[0013] In some embodiments, the workbench further comprises a sensing device, which is used to sense the sheet material. By providing the sensing device, the sheet material can be positioned, thereby improving the efficiency of positioning.

[0014] In some embodiments, the sheet positioning device further includes a positioning mechanism, which includes a positioning camera and a graphic comparison device. The positioning camera is arranged on one side of the workbench and is used to photograph the position pattern of the sheet. The graphic comparison device is electrically connected to the positioning camera and is used to compare the position pattern with the standard pattern. The positioning camera is set to obtain the position of the sheet after it moves. After the sheet moves through the first pushing device and the second pushing device, the positioning camera can capture the position image of the sheet to quickly obtain the precise position information of the sheet after it moves. The graphic comparison device is used to compare the sheet position image captured by the positioning camera with the preset "standard position" image. And the graphic comparison device can determine the difference between the current position of the sheet and the preset standard position through a software algorithm. When the position of the sheet deviates from the preset standard position, the graphic comparison device can send a signal or indication for further adjustment or calibration. In the above structure, through real-time capture and comparison, the positioning camera and the graphic comparison device can quickly find the position deviation and calibrate in time. This greatly reduces the positioning time and improves the overall production efficiency. And because of the use of image processing and comparison technology, this method can further improve the position accuracy of the sheet.

[0015] In some embodiments, the positioning mechanism further includes a control device, which is electrically connected to the graphic comparison device and the first driving motor. The control device is responsible for monitoring the entire positioning process and making decisions based on the data provided by the graphic comparison device. When the graphic comparison device determines that the position of the sheet does not meet the preset standard, the control device will immediately identify this deviation and respond accordingly. By combining the control device with the graphic comparison device, a closed-loop feedback system is formed. When the position of the sheet does not meet the standard, the system will automatically adjust until it meets the preset standard. Since the control device can automatically identify and respond to deviations in the position of the sheet, the need for manual participation and intervention is greatly reduced. Under automated control, the equipment can operate continuously and stably, thereby improving production efficiency. Automated control reduces the possibility of human error, thereby improving the reliability and stability of the overall operation.

[0016] In some embodiments, the sheet positioning device further includes a feeding mechanism, which includes a feeding platform and a moving device. The feeding platform is arranged on one side of the base, and the feeding platform is used to support the sheet. The moving device is arranged between the feeding platform and the workbench, and the moving device is used to move the sheet to one side of the workbench. In the above structure, through the combination of the feeding mechanism and the moving device, the sheet can be automatically transferred from the feeding platform to the workbench, thereby realizing automated operation. This not only reduces the manual operation links, but also improves work efficiency and reduces production costs. The design of the feeding platform ensures that the sheet has stable support before transfer, and reduces the possibility of sheet sliding or tipping during the transfer process. The precise control of the moving device ensures that the sheet can be accurately placed at the designated position on the workbench, thereby improving the positioning accuracy of the sheet. In addition, the sheet can be continuously transported from the feeding platform to the workbench, thereby ensuring the continuity of production and helping to improve production efficiency and output.

[0017] In some embodiments, the moving device includes a support seat and a three-way moving device. The three-way moving device is arranged between the feeding platform and the workbench, the support seat is arranged on the three-way moving device, and the support seat is used to support the sheet material. The three-way moving device is used to drive the support seat to move along the first direction, the second direction and the third direction, and the third direction intersects with the plane where the first direction and the second direction are located.

[0018] By setting up a three-way moving device, the support seat can be driven to move along the first direction, the second direction and the third direction, and the support seat can be flexibly and accurately positioned in three-dimensional space. In particular, the third direction intersects with the plane where the first direction and the second direction are located. This design allows the moving device to move perpendicular to the plane of the workbench, thereby adapting to more complex assembly scenarios. The support seat is provided so that the sheet can remain stable during the movement, reducing the shaking or tilting that may occur during the movement. The precise control of the three-way moving device ensures that the sheet can be accurately placed at the designated position on the workbench, thereby improving the positioning accuracy of the sheet. Due to the design of the moving device, the operator can complete the movement and positioning operations of the sheet more easily and quickly, reducing the difficulty of operation and labor intensity. Therefore, the above structure can effectively improve the efficiency of sheet positioning and the production efficiency of battery cells.

[0019] In a second aspect, the present application provides a battery manufacturing system, which includes the sheet positioning device in the above-mentioned embodiment.

[0041] Please refer to Figure 2 , Figure 2 This is an exploded view of a battery provided in one embodiment of the present application. The battery 2 includes a box body 5 and a battery cell 7, and the battery cell 7 is accommodated in the box body 5. The box body 5 is used to provide an accommodating space 53 for the battery cell 7, and the box body 5 can adopt a variety of structures.

[0042] In some optional embodiments, the box body 5 includes a first part 51 and a second part 52, the first part 51 and the second part 52 cover each other, and the first part 51 and the second part 52 jointly define a receiving space 53 for receiving the battery cell 7.

[0044] In some embodiments, the first part 51 or the second part 52 may include a frame and a cover plate, and the frame includes a plurality of beam structures.

[0045] In the battery 2, there can be multiple battery cells 7, and the multiple battery cells 7 can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 7 are both connected in series and in parallel. The multiple battery cells 7 can be directly connected in series, in parallel, or in mixed connection, and then the whole formed by the multiple battery cells 7 is accommodated in the box 5. Of course, the battery 2 can also be a battery module formed by connecting multiple battery cells 7 in series, in parallel, or in mixed connection, and then the multiple battery modules are connected in series, in parallel, or in mixed connection to form a whole, and accommodated in the box 5.

[0046] Each battery cell 7 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. The battery cell 7 may be cylindrical, flat, rectangular or in other shapes.

[0047] Please refer to Figure 3 , Figure 3 The schematic diagram of the structure of a battery cell 7 provided in one embodiment of the present application. The battery cell 7 refers to the smallest unit constituting the battery 2. Figure 3 The battery cell 7 includes a housing 40, an electrode assembly 10 and other functional components. The housing 40 may include an end cap 30 and a shell 20. The end cap 30 is a component that covers the opening of the shell 20 to isolate the internal environment of the battery cell 7 from the external environment.

[0048] The electrode assembly 10 is a component in the battery cell 7 where electrochemical reactions occur. One or more electrode assemblies 10 may be contained in the housing 20. The electrode assembly 10 includes a positive electrode sheet, a negative electrode sheet, and a separator. The positive electrode sheet includes a sheet, a positive electrode active material, and a binder. The negative electrode sheet includes a sheet, a negative electrode active material, and a binder. The positive electrode active material and the negative electrode active material contain active ions. During the charge and discharge process of the battery cell 7, active ions (such as lithium ions) are embedded and removed back and forth between the positive electrode sheet and the negative electrode sheet. The separator is arranged between the positive electrode sheet and the negative electrode sheet, which can prevent the positive and negative electrodes from short-circuiting, and at the same time allow active ions to pass through.

[0049] In some embodiments, the battery cell 7 also includes an electrolyte, which plays a role in conducting ions between the positive and negative electrodes. The present application does not specifically limit the type of electrolyte, which can be selected according to needs. The electrolyte can be liquid, gel or solid. In some embodiments, the electrode assembly 10 is a winding structure. Optionally, the electrode assembly 10 is a laminated structure.

[0050] In some embodiments, the battery cell 7 also includes a film 50, and the film 50 is arranged on the outer side of the shell 20 away from the accommodating cavity. The film 50 can be used to insulate the shell 20, or to transfer heat between two adjacent battery cells 7. When the battery cell 7 is glued, there is a phenomenon of crooked glue sticking, which leads to unqualified process parameters and requires re-glueing, which reduces efficiency and yield rate. Therefore, it is necessary to improve the accuracy of the positioning of the film 50. Before molding, the film 50 is a sheet structure cut into a preset size. After the sheet is accurately positioned, it can be placed in the designated position by a mobile device for gluing to improve the accuracy of the gluing position.

[0051] Based on the above problems, an embodiment of the present application provides a sheet positioning device. A workbench is provided in the sheet positioning device to provide stable support for the sheet, and at the same time ensure that the pushing device can work on a flat and stable surface, thereby improving the stability of the entire positioning process. Therefore, when pushing the sheet, no unexpected displacement or vibration will occur, which improves the accuracy of controlling the position of the sheet. And a first pushing device and a second pushing device are provided to work together to push the sheet in different directions (first direction and second direction) respectively. This design allows multi-dimensional adjustment and control of the sheet to ensure that it can be accurately aligned with the limit block. By accurately controlling the position of the sheet in two directions, high-precision positioning of the sheet can be achieved. In summary, the design of the sheet positioning device makes full use of the stability of the workbench and the precise control ability of the pushing device, ensuring that the sheet is quickly and accurately positioned, which can improve production efficiency while ensuring product quality.

[0052] The following is a detailed description of the sheet positioning device in the embodiment of the present application in conjunction with the accompanying drawings. Figures 4 to 6 , Figure 4 This is a schematic diagram of the structure of a sheet positioning device according to an embodiment of the present application. Figure 5 This is a structural schematic diagram of a sheet positioning device according to another embodiment of the present application. Figure 6 This is a schematic structural diagram of a feeding mechanism according to an embodiment of the present application.

[0053] As shown in the figure, the positioning device of the embodiment of the present application includes a workbench 601, a first limit block 602, a second limit block 603, a first push device 604 and a second push device 605. The workbench 601 is used to support the sheet 8, the first limit block 602 is arranged on one side of the workbench 601 along the first direction X, and the second limit block 603 is arranged on one side of the workbench 601 along the second direction Y, and the second direction Y intersects with the first direction X. The first push device 604 is used to push the sheet 8 to move along the first direction X. The second push device 605 is used to push the sheet 8 to move along the second direction Y. Among them, the first push device 604 and the second push device 605 can push the sheet 8 to abut against the first limit block 602 and the second limit block 603.

[0054] For example, the positioned sheet 8 can be moved by the robot arm and attached to the outside of the battery cell 7. After the sheet 8 is positioned on the workbench 601, the position and moving path of the robot arm are also fixed. When the position and moving path of the robot arm grabbing the sheet 8 are fixed, the accurate assembly of the sheet 8 can be achieved, thereby improving the accuracy of the installation of the sheet 8.

[0055] In the technical solution of the embodiment of the present application, the workbench 601 not only provides stable support for the sheet 8, but also ensures that the pushing device can work on a flat and stable platform, thereby improving the stability of the entire positioning process. Therefore, when pushing the sheet 8, no unexpected displacement or vibration will occur, which improves the accuracy of controlling the position of the sheet 8. The first pushing device 604 and the second pushing device 605 work together to push the sheet 8 in different directions (the first direction X and the second direction Y). This design can adjust and control the sheet 8 in multiple dimensions to ensure that it can be accurately aligned with the limit block. By accurately controlling the position of the sheet 8 in two directions, high-precision positioning of the sheet 8 can be achieved. In summary, the design of the sheet positioning device 6 makes full use of the stability of the workbench 601 and the precise control ability of the pushing device, ensuring that the sheet 8 is quickly and accurately positioned, which can improve production efficiency and ensure product quality. When the outer dimensions of the sheet 8 are fixed, when any two adjacent sides of the sheet 8 are positioned, the precise positioning of the sheet 8 can be achieved.

[0056] In some optional embodiments, the first limiting block 602 includes a first limiting strip, the first limiting strip protrudes from the surface of the workbench 601, and the first limiting strip is arranged at the edge of the workbench 601 along the first direction X. When the first pushing device 604 pushes the sheet 8 to move along the first defense line, it cannot move when it moves to the first limiting strip, thereby achieving the positioning of the sheet 8 in the first direction X. The second limiting block 603 includes a second limiting strip, the second limiting strip protrudes from the surface of the workbench 601, and the second limiting strip is arranged at the edge of the workbench 601 along the second direction Y. When the second pushing device 605 pushes the sheet 8 to move along the second defense line, it cannot move when it moves to the second limiting strip, thereby achieving the positioning of the sheet 8 in the second direction Y.

[0057] In some optional embodiments, the first direction X is perpendicular to the second direction Y, and the first limit block 602 and the second limit block 603 are respectively arranged on two adjacent sides of the workbench 601. Optionally, the first limit block 602 and the second limit block 603 are an integrally formed structure. The above structure improves the efficiency of production and installation of the first limit block 602 and the second limit block 603.

[0058] In some embodiments of the present application, the first pushing device 604 includes a first pushing block 606 and a first pushing motor 607. The first pushing block 606 is arranged opposite to the first limit block 602 and is respectively arranged on both sides of the sheet 8 along the first direction X. The first pushing motor 607 is connected to the first pushing block 606, and the first pushing motor 607 is used to push the first pushing block 606 to move along the first direction X. In the above technical solution, the first pushing motor 607 can provide continuous and uniform thrust, and the first pushing block 606 will not suddenly accelerate or decelerate during the movement, thereby ensuring a smooth movement trajectory. This smoothness can improve the position accuracy of the sheet 8 and the control efficiency of the positioning of the sheet 8.

[0059] In some embodiments of the present application, the sheet positioning device 6 further includes a base 608, the number of workbenches 601 is N, the N workbenches 601 are arranged at intervals on the base 608, the number of first push blocks 606 is N, and the first push device 604 includes a first connecting block 609. The N first push blocks 606 are respectively connected to the first connecting blocks 609, and the first connecting blocks 609 are connected to the first push motor 607. N is a positive integer, and the number of the first push blocks 606 is equal to the number of the workbenches 601 and is arranged one by one. Optionally, the N workbenches 601 are arranged in sequence along the first direction X or the second direction Y.

[0060] In the above structure, by providing the base 608, the number of workbenches 601 is increased, and the sheet positioning device 6 can simultaneously position multiple sheets 8, thereby improving the efficiency of positioning the sheets 8. Furthermore, by simultaneously positioning multiple sheets 8, the production cycle can be shortened, thereby improving the overall production efficiency of the battery cell 7. Furthermore, by being arranged along the first direction X or the first direction X, it is convenient to arrange the pushing device.

[0061] In some embodiments of the present application, the first pushing motor 607 and the first connecting block 609 are respectively arranged on opposite sides of the base 608, and the base 608 is provided with a first sliding groove that penetrates along the thickness direction of the base 608. One end of the first pushing motor 607 passes through the first sliding groove and is connected to the first connecting block 609.

[0062] In the above technical solution, the first pushing motor 607 and the first connecting block 609 are respectively arranged on both sides of the base 608, the first connecting block 609 is connected to the workbench 601, the workbench 601 and the first pushing motor 607 can be respectively arranged on both sides of the base 608, so as to facilitate the observation of the pushing of the first connecting block 609. The operator or maintenance personnel can more easily see the movement of the first connecting block 609 and the first pushing block 606 and the interaction with other components; at the same time, the rationality of space utilization is improved, making the overall structure more compact and efficient.

[0063] In some optional embodiments, the second pushing device 605 includes a second pushing block 610 and a second pushing motor 611. The second pushing block 610 is arranged opposite to the second limit block 603 and is respectively arranged on both sides of the sheet 8 along the second direction Y. The second pushing motor 611 is connected to the second pushing block 610, and the second pushing motor 611 is used to push the second pushing block 610 to move along the second direction Y. The number of the second pushing blocks 610 is N, and the second pushing device 605 includes a second connecting block 612. The N second pushing blocks 610 are respectively connected to the second connecting block 612, and the second connecting block 612 is connected to the second pushing motor 611. N is a positive integer, and the number of the second pushing blocks 610 is equal to the number of the workbenches 601 and is arranged one by one.

[0064] In some optional embodiments, N workbenches 601 are sequentially arranged along the first direction X or the second direction Y. The second pushing motor 611 and the second connecting block 612 are respectively arranged on opposite sides of the base 608, and the base 608 is provided with a second slide groove penetrating along the thickness direction of the base 608, and one end of the second pushing motor 611 passes through the second slide groove and is connected to the second connecting block 612.

[0065] In some embodiments, a first slide rail 613 extending along a first direction X is provided on the base 608, and a first groove cooperating with the first slide rail 613 is provided on the first push block 606, and the first slide rail 613 is slidably connected to the first groove. In the above structure, the first slide rail 613 is provided, and the first push block 606 can move on a predetermined path to ensure the accuracy and stability of the movement. When the first push block 606 moves along the first slide rail 613, the first groove ensures that it remains in the correct position and direction to prevent displacement or misoperation. The first slide rail 613 cooperates with the first groove to reduce friction and resistance, making the movement of the first push block 606 smoother and easier to control. Therefore, the first push block 606 can move more accurately and efficiently on the base 608, thereby improving the accuracy and efficiency of the positioning control of the sheet 8. The above technical solution improves the production efficiency and product quality of the battery cell 7 by optimizing the positioning performance of the sheet positioning device 6.

[0066] In some embodiments of the present application, the surface of one side of the workbench 601 facing the sheet 8 is concave to form an anti-sticking groove 614. Exemplarily, the anti-sticking groove 614 is strip-shaped or curved. By providing the concave anti-sticking groove 614, the risk of vacuum adsorption of the sheet 8 and the surface of the workbench 601 is reduced, and air is allowed to flow in the anti-sticking groove 614, thereby eliminating or reducing the vacuum adsorption force. When the sheet 8 is no longer hindered by vacuum adsorption, it can move more smoothly on the workbench 601. This not only speeds up the movement of the sheet 8, but also reduces the additional operation steps caused by adsorption and release. Since the anti-sticking groove 614 reduces the interference of vacuum adsorption, the sheet 8 can be more easily moved to a predetermined position, thereby improving the accuracy of the positioning of the sheet 8, thereby improving the product quality and production efficiency of the battery cell 7.

[0067] In some embodiments, the workbench 601 further includes a sensing device, which is used to sense the sheet 8. Exemplarily, the sensing device includes a light sensor or a pressure sensor, which is used to sense whether the sheet 8 reaches a preset position. By providing a sensor, the sheet 8 can be positioned, thereby improving the efficiency of positioning.

[0068] In some embodiments of the present application, the sheet positioning device 6 further includes a positioning mechanism, which includes a positioning camera 615 and a graphic comparison device. The positioning camera 615 is arranged on one side of the workbench 601, and is used to photograph the position pattern of the sheet 8. The graphic comparison device is electrically connected to the positioning camera 615, and is used to compare the position pattern with the standard pattern. The positioning camera 615 is set to obtain the position of the sheet 8 after it moves. After the sheet 8 moves through the first pushing device 604 and the second pushing device 605, the positioning camera 615 can capture the position image of the sheet 8 to quickly obtain the precise position information of the sheet 8 after it moves. The graphic comparison device is used to compare the position image of the sheet 8 captured by the positioning camera 615 with the preset "standard position" image. And the graphic comparison device can determine the difference between the current position of the sheet 8 and the preset standard position through a software algorithm. When the position of the sheet 8 deviates from the preset standard position, the graphic comparison device can send a signal or indication for further adjustment or calibration. With the above structure, through real-time capture and comparison, the positioning camera 615 and the graphic comparison device can quickly find the position deviation and calibrate in time. This greatly reduces the positioning time and improves the overall production efficiency. And due to the use of image processing and contrast technology, this method can further improve the position accuracy of the sheet 8.

[0069] In some embodiments of the present application, the positioning mechanism further includes a control device, and the control device is electrically connected to the pattern comparison device and the first driving motor 607 respectively.

[0070] Among them, the control device is responsible for monitoring the entire positioning process and making decisions based on the data provided by the graphic comparison device. When the graphic comparison device determines that the position of the sheet 8 does not meet the preset standard, the control device will immediately identify this deviation and respond accordingly. Through the combination of the control device and the graphic comparison device, a closed-loop feedback system is formed. When the position of the sheet 8 does not meet the standard, the system will automatically adjust until it meets the preset standard. Since the control device can automatically identify and respond to deviations in the position of the sheet 8, the need for human participation and intervention is greatly reduced. Under automated control, the equipment can operate continuously and stably, improving production efficiency. Automated control reduces the possibility of human error, thereby improving the reliability and stability of the overall operation.

[0071] In some embodiments of the present application, the sheet positioning device 6 further includes a feeding mechanism, which includes a feeding platform 616 and a moving device. The feeding platform 616 is provided on one side of the base 608, and the feeding platform 616 is used to support the sheet 8. The moving device is provided between the feeding platform 616 and the workbench 601, and the moving device is used to move the sheet 8 to one side of the workbench 601.

[0072] In the above structure, through the combination of the feeding mechanism and the moving device, the sheet 8 can be automatically transferred from the feeding platform 616 to the workbench 601, thereby realizing automated operation. This not only reduces the manual operation links, but also improves work efficiency and reduces production costs. The design of the feeding platform 616 ensures that the sheet 8 has stable support before transfer, reducing the possibility of the sheet 8 sliding or tipping during the transfer process. The precise control of the moving device ensures that the sheet 8 can be accurately placed at the designated position on the workbench 601, thereby improving the positioning accuracy of the sheet 8. In addition, the sheet 8 can be continuously transported from the feeding platform 616 to the workbench 601, thereby ensuring the continuity of production and helping to improve production efficiency and output.

[0073] In some embodiments, the moving device includes a support seat 617 and a three-way moving device. The three-way moving device is disposed between the feeding platform 616 and the workbench 601, and the support seat 617 is disposed on the three-way moving device, and the support seat 617 is used to support the sheet 8. The three-way moving device is used to drive the support seat 617 to move along the first direction X, the second direction Y, and the third direction Z, and the third direction Z intersects with the plane where the first direction X and the second direction Y are located.

[0074] Exemplarily, the three-way moving device includes a first motor, a second motor and a third motor. The first motor can drive the support seat 617 to move along the first direction X, the second motor can drive the support seat 617 to move along the second direction Y, and the third motor can drive the support seat 617 to move along the third direction Z. After the three-way moving device moves the sheet 8 on the support seat 617 to the vicinity of the workbench 601, the sheet 8 can be moved to the workbench 601 using a mechanical arm, and then the sheet 8 positioning mechanism can be used to accurately position the sheet 8. Exemplarily, by controlling the three-way moving device, the sheet 8 can be moved to the preset workbench 601. When the number of workbenches 6001 is multiple, the three-way moving device can improve the efficiency of the movement of the sheet 8 and the accuracy of the moving position.

[0075] By setting a three-way moving device, the support seat 617 can be driven to move along the first direction X, the second direction Y and the third direction Z, and the support seat 617 can be flexibly and accurately positioned in three-dimensional space. In particular, the third direction Z intersects with the plane where the first direction X and the second direction Y are located. This design allows the mobile device to move perpendicular to the plane of the workbench 601, thereby adapting to more complex assembly scenarios. The support seat 617 is set so that the sheet 8 can remain stable during the movement, reducing the shaking or tilting that may occur during the movement. The precise control of the three-way moving device ensures that the sheet 8 can be accurately placed at the designated position on the workbench 601, thereby improving the positioning accuracy of the sheet 8. Due to the design of the moving device, the operator can complete the movement and positioning operations of the sheet 8 more easily and quickly, reducing the difficulty of operation and labor intensity. Therefore, the above structure can effectively improve the efficiency of the positioning of the sheet 8 and the production efficiency of the battery cell 7.

[0076] In the second aspect, the present application provides a battery manufacturing system, which includes the sheet positioning device 6 in the above embodiment. The workbench 601 not only provides stable support for the sheet 8, but also ensures that the pushing device can work on a flat and stable surface, thereby improving the stability of the entire positioning process. Therefore, when pushing the sheet 8, no unexpected displacement or vibration will occur, which improves the accuracy of controlling the position of the sheet 8. The first pushing device 604 and the second pushing device 605 work together to push the sheet 8 in different directions (first direction X and second direction Y). This design allows multi-dimensional adjustment and control of the sheet 8 to ensure that it can be accurately aligned with the limit block. By accurately controlling the position of the sheet 8 in two directions, high-precision positioning of the sheet 8 can be achieved. In summary, the design of the sheet positioning device 6 makes full use of the stability of the workbench 601 and the precise control ability of the pushing device, ensuring that the sheet 8 is quickly and accurately positioned, which can improve production efficiency while ensuring product quality.
