[0083] The manufacturing process of the battery cell is generally to assemble the electrode assembly into the housing after the electrode assembly is formed into a shape, and then to inject electrolyte into the housing. The above-mentioned electrode assembly assembly process and electrolyte injection process are usually carried out in different workshops. After the assembly of the housing is completed, the housing and the electrode assembly therein need to be transferred to the electrolyte injection workshop, and the electrolyte injection hole on the housing and the electrolyte injection nozzle on the electrolyte injection device need to be accurately aligned before the electrolyte injection. The above-mentioned process needs to move the battery cell, so higher requirements are put forward for the transportation efficiency and the transportation position accuracy of the carrying equipment. The commonly used carrying equipment can only realize movement or only realize lifting, and the battery cell needs to be transferred between two equipment, which prolongs the carrying time and reduces the production efficiency.

[0084] Based on the above problems, the embodiment of the present application provides a carrying device. The carrying device is provided with a moving mechanism. The moving mechanism can move the battery monomer along the first direction and move the battery monomer to the vicinity of the target position. For example, the moving mechanism can move the battery monomer from the electrode assembly into the shell assembly factory to the liquid injection factory. The telescopic mechanism telescopes the carried object to one side of the moving mechanism, and accurately transports the carried object to below the liquid injection nozzle of the liquid injection device. The jacking mechanism is provided to lift or lower the battery monomer, and align the liquid injection hole on the battery monomer with the liquid injection nozzle. Through the cooperation of the moving mechanism, the jacking mechanism and the telescopic mechanism, the battery monomer can be accurately moved to the liquid injection nozzle for electrolyte injection, thereby improving the accuracy of the battery monomer moving position and the liquid injection efficiency of the battery monomer.

[0086] As shown in FIG. 4, the carrying device 101 provided by the embodiment of the present application comprises a moving mechanism 6, a jacking mechanism 7 and a telescopic mechanism 8. The moving mechanism 6 comprises a moving plate 601, and the moving plate 601 can move along the first direction X. The jacking mechanism 7 is arranged on the moving plate 601, and the telescopic mechanism 8 is connected to the jacking mechanism 7, and the telescopic mechanism 8 can move along the second direction Y relative to the moving plate 601. The second direction Y intersects the first direction X, and the telescopic mechanism 8 is used for carrying the carried object. The jacking mechanism 7 is used for driving the telescopic mechanism 8 to move along the third direction Z relative to the moving plate 601, and the third direction Z intersects the plane in which the first direction X and the second direction Y are located.

[0087] The moving mechanism 6 can be a conveyor belt or a moving trolley. The moving plate 601 is arranged on the conveyor belt or the moving trolley and can move with the conveyor belt. The jacking mechanism 7 is arranged on the moving plate 601 and moves with the moving plate 601. The telescopic mechanism 8 is arranged on the jacking mechanism 7 and can also move with the moving plate 601. After the battery monomer 50 completes the shell assembly of the electrode assembly 10, the battery monomer 50 can be directly placed on the telescopic assembly so as to be transported to the vicinity of the liquid injection device along with the movement of the moving plate 601.

[0088] For example, the first direction X can be perpendicular to the second direction Y, and the plane in which the first direction X and the second direction Y are located is a horizontal plane. The third direction Z can be a vertical direction perpendicular to the horizontal plane.

[0089] The moving mechanism 6 is generally arranged on one side of the liquid injection device along the second direction Y. By controlling the moving path of the moving plate 601, the battery monomer 50 can be transported to the side of the liquid injection device along the second direction Y. With such an arrangement, as long as the telescopic mechanism 8 is controlled to move along the second direction Y, the battery monomer 50 can be moved to the lower side of the liquid injection nozzle. Finally, by moving the jacking mechanism 7, the liquid injection hole of the battery monomer 50 can be aligned with the liquid injection nozzle of the liquid injection device for liquid injection.

[0090] In the technical solution of the embodiment of the application, the moving mechanism 6 is arranged to move the carried object along the first direction X to move the carried object to the vicinity of the target position. The jacking mechanism 7 is arranged to lift or lower the carried object to realize movement in the height direction. The telescopic mechanism 8 telescopes the carried object to the side of the moving mechanism 6 to accurately transport the carried object to the target position. The carried object can be the battery monomer 50, and the target position can be the electrolyte liquid injection nozzle. Through the cooperation of the moving mechanism 6, the jacking mechanism 7, and the telescopic mechanism 8, the battery monomer 50 can be accurately moved to the liquid injection nozzle for electrolyte liquid injection, thereby improving the accuracy of the movement of the battery monomer 50 and the efficiency of the liquid injection of the battery monomer 50.

[0091] In some optional embodiments, the number of moving plates 601 can be N. Correspondingly, the number of jacking mechanisms 7 and telescopic mechanisms 8 is also N, and the jacking mechanisms 7 and the telescopic mechanisms 8 are arranged one by one corresponding to the moving plates 601, which can increase the number of carried objects and improve the carrying efficiency. For example, as shown in FIG. 4, the number of moving plates 601 is two, and each moving plate 601 is provided with one jacking mechanism 7 and one telescopic mechanism 8.

[0092] In some embodiments of the application, the carrying device 101 further comprises a liquid collecting mechanism 9, which comprises a liquid collecting assembly 90 and a liquid collecting plate 901. The liquid collecting assembly 90 can move along the second direction Y relative to the moving plate 601, and the liquid collecting plate 901 is connected to the liquid collecting assembly 90 and located on the side of the telescopic mechanism 8 away from the moving plate 601. For example, the liquid collecting plate 901 is arranged on the side of the battery monomer 50 facing the liquid injection device.

[0093] In the above structure, by arranging the liquid collecting mechanism 9, the battery monomer 50 that has completed liquid injection is protected, and a small amount of liquid dripping from the liquid injection nozzle is collected, thereby reducing the damage of the electrolyte liquid to the shell 40 of the battery monomer 50 and improving the yield of the battery monomer 50.

[0094] As shown in FIGS. 5-7, in some embodiments of the present application, the jacking mechanism 7 includes a frame 70, a connecting rod 702, a curved rod 703, and a moving rod 704. The frame 70 is connected to the moving plate 601, and the frame 70 includes a first side plate 701. The connecting rod 702 is rotatably connected to the first side plate 701, and the axial direction of the connecting rod 702 is along the first direction X. One end of the curved rod 703 is connected to the connecting rod 702, and the other end of the curved rod 703 is bent opposite to the connecting rod 702. The moving rod 704 is connected to the end of the curved rod 703 away from the connecting rod 702, and the axial direction of the moving rod 704 is along the first direction X. The rotation of the connecting rod 702 along the axial direction can drive the moving rod 704 to move through the curved rod 703, and the telescopic mechanism 8 moves along the third direction Z under the movement of the moving rod 704.

[0095] One end of the connecting rod 702 extends into the frame 70 through the first side plate 701, and the curved rod 703 and the moving rod 704 are arranged in the frame 70. The curved rod 703 and the moving rod 704 are mounted on the frame 70 through the connecting rod 702. The connecting rod 702 and the moving rod 704 are arranged in parallel with each other, the curved rod 703 is connected between the connecting rod 702 and the moving rod 704, and the axial direction of the curved rod 703 intersects with the axial directions of the connecting rod 702 and the moving rod 704. The connecting rod 702, the curved rod 703, and the moving rod 704 form a structure similar to the letter "Z".

[0096] Optionally, the number of the connecting rod 702 and the curved rod 703 is two, two curved rods 703 are connected to the two ends of the moving rod 704, and two connecting rods 702 are arranged on opposite sides of the frame 70. The two connecting rods 702 are coaxially arranged. The two connecting rods 702, the two curved rods 703, and the moving rod 704 form a symmetrical bent shape similar to the letter "J".

[0097] Optionally, the telescopic mechanism 8 can be directly connected to the moving rod 704 or indirectly connected to the moving rod 704 through other components.

[0098] In the above technical solution, the frame 70 is a support structure of the entire mechanism, which is used to concentrate other components in the jacking mechanism 7 and improve the stability of the jacking process. The frame 70 usually needs to have high structural strength to withstand various forces and moments generated during the jacking process. The rotation of the connecting rod 702 can be achieved by a driving device such as a motor, a hydraulic cylinder or a pneumatic cylinder. The rotation of the connecting rod 702 is the starting point of the mechanism movement. The curved rod 703 is a curved component connected to the connecting rod 702. Its shape and size are designed to be just right to produce the desired movement effect when the connecting rod 702 rotates. The curved rod 703 is bent relative to the connecting rod 702, and this bending allows the curved rod 703 to produce movement in one direction when the connecting rod 702 rotates. The moving rod 704 is another key component in the mechanism, which can rotate around the axis of the connecting rod 702 and realize the movement in the third direction Z (i.e. lifting movement) in rotation. This movement is driven by the movement of the curved rod 703. The moving rod 704 usually has a jacking platform or other components that need to be lifted.

[0099] The rotation of the connecting rod 702 can be converted into the lifting movement of the moving rod 704 in the third direction Z by the above structure. This conversion is achieved by the shape and size design of the curved rod 703 and the connection mode between the curved rod 703 and the connecting rod 702 and the moving rod 704. When the connecting rod 702 rotates, the curved rod 703 will move with it and drive the moving rod 704 to rotate around the axis of the connecting rod 702 and realize the lifting movement in rotation.

[0100] As shown in FIGS. 5-8, in some embodiments of the present application, the jacking mechanism 7 further comprises a first driving assembly, which comprises a jacking driving motor 706, a driving rod 707, a first gear 708 and a second gear 709. The driving rod 707 is connected to the jacking driving motor 706, and the driving rod 707 rotates around the axis under the driving of the jacking driving motor 706. The first gear 708 is connected to the driving rod 707, and the second gear 709 is engaged with the first gear 708. The second gear 709 is connected to the connecting rod 702, and the second gear 709 can drive the connecting rod 702 to rotate.

[0101] In the above structure, through the control of the jacking driving motor 706, the lifting and lowering speed of the battery monomer 50 and the stop position can be accurately controlled, and the automation degree of the jacking mechanism 7 is improved. By using the gear 808 transmission system, a high-precision transmission ratio can be achieved, so as to ensure the accurate movement of the moving rod 704 in the third direction Z. Due to the use of the gear 808 transmission, compared with other transmission modes (such as belt transmission or chain transmission), the transmission process is more stable, and the position deviation of the moving rod 704 caused by transmission error is reduced. The gear 808 transmission system allows a larger transmission ratio in a limited space, so the entire jacking mechanism 7 can be designed more compactly, reducing the occupied space. The gear 808 transmission system is relatively simple, and the connection between the components is clear and understandable, so it is easy to maintain and replace.

[0102] By setting the first driving assembly and using the jacking driving motor 706, the driving rod 707, the first gear 708 and the second gear 709 and other components, accurate control of the rotation of the connecting rod 702 can be achieved, and then the automatic lifting and lowering movement of the battery monomer 50 in the third direction Z is realized, improving the automation degree and stability of the jacking mechanism 7.

[0103] In some optional embodiments, a connecting gear 710 is further arranged between the first gear 708 and the second gear 709, and the first gear 708 and the second gear 709 are respectively engaged with the connecting gear 710. The rotation of the first gear 708 drives the connecting gear 710 and the second gear 709 in turn.

[0104] As shown in FIG. 5 and FIG. 9, in some embodiments of the present application, the frame 70 further comprises a second side plate 711 arranged adjacent to the first side plate 701, and the jacking mechanism 7 further comprises a limiting assembly 712, which comprises a limiting frame 713, a first limiting piece 714 and a second limiting piece 715. The limiting frame 713 has an accommodation cavity 716, and the moving rod 704 penetrates through the accommodation cavity 716. The telescopic mechanism 8 is connected to the side of the limiting frame 713 away from the accommodation cavity 716. The first limiting piece 714 is arranged on the first side plate 701, and abuts one side of the limiting frame 713. The second limiting piece 715 is arranged on the second side plate 711, and abuts the other side of the limiting frame 713. The second limiting piece 715 is arranged on the side of the first limiting piece 714 along the second direction Y. Wherein, the limiting frame 713 is driven by the connecting rod 702 to move along the third direction Z relative to the frame 70, and the first limiting piece 714 and the second limiting piece 715 can limit the movement of the limiting frame 713 along the second direction Y.

[0105] The frame 70 provides stable structural support for other components in the jacking mechanism 7. The frame 70 generally further comprises a third side plate 717 and a fourth side plate 718, which are sequentially connected to form a stable frame 70 structure. The first side plate 701 is provided with a connecting hole 705, and the connecting rod 702 passes through the connecting hole 705 in the axial direction to be rotatably connected to the first side plate 701.

[0106] The accommodation cavity 716 in the limiting frame 713 has a certain width in the second direction Y. When the moving rod 704 moves in the second direction Y, the moving rod 704 can move in the accommodation cavity 716 without pushing the limiting frame 713 to move in the second direction Y, so as to absorb the movement displacement of the moving rod 704 in the second direction Y, thereby ensuring the stability of the position of the telescopic mechanism 8 on the limiting frame 713 in the second direction Y.

[0107] The first limiting member 714 and the second limiting member 715 can be strip-shaped structures, and the two ends of the first limiting member 714 and the second limiting member 715 extend in the third direction Z. The first limiting member 714, the first side plate 701, and the second limiting member 715 define a moving channel extending in the third direction Z, and the limiting frame 713 can move in the moving channel in the third direction Z.

[0108] In the above structure, the first side plate 701 and the second side plate 711 provide stable mounting surfaces for the first limiting member 714 and the second limiting member 715, thereby improving the constraint on the limiting frame 713 and limiting the movement of the limiting frame 713 in the left-right direction. The moving rod 704 is arranged in the accommodation cavity 716, and when the moving rod 704 moves, it drives the limiting frame 713 to move. The space in the accommodation cavity 716 can absorb part of the movement of the moving rod 704 in the second direction Y, thereby maintaining the stability of the position of the carried object in the second direction Y. In addition, the limiting frame 713 can move in the third direction Z during the rotation of the moving rod 704, and drive the carried object to move in the third direction Z.

[0109] As shown in FIG. 7, in some embodiments of the present application, the limiting assembly 712 further comprises a bearing 719, which is sleeved on the moving rod 704 and is in sliding connection with the moving rod 704.

[0110] For example, the bearing 719 comprises an inner ring and an outer ring which are sequentially sleeved on the moving rod 704, and further comprises a plurality of balls arranged between the inner ring and the outer ring.

[0111] The above structure reduces the direct contact area between the moving rod 704 and the limiting frame 713 during movement, thereby reducing the friction therebetween. Reducing the friction not only makes the moving rod 704 easier and smoother to move, but also reduces energy loss and heat generation. Without the bearing 719, the moving rod 704 can be squeezed by the limiting frame 713 during movement, especially under high load or fast movement. The bearing 719, as an independent sliding element, can withstand such squeezing and disperse it over a larger area, thereby reducing damage to the moving rod 704 and the limiting frame 713. By reducing friction and reducing squeezing, the bearing 719 can significantly prolong the service life of the jacking mechanism 7. The reduced wear and tear of the moving rod 704 and the limiting frame 713 make the entire mechanism more durable and reliable.

[0112] As shown in FIG. 9, in some embodiments of the present application, the jacking mechanism 7 further comprises a guide assembly 720, which includes a sliding groove 721 and a pulley 722. The sliding groove 721 is recessed along the surface of the first limiting member 714 and / or the second limiting member 715, and the two ends of the sliding groove 721 extend in the third direction Z. The pulley 722 is provided on the limiting frame 713 and is in sliding connection with the sliding groove 721.

[0113] In the above structure, by providing the pulley 722 and the sliding groove 721, the friction between the limiting frame 713 and the first limiting member 714 and the second limiting member 715 is effectively reduced, the sliding efficiency of the limiting frame 713 in the third direction Z is improved, the lifting process of the jacking mechanism 7 is smoother, the energy consumption is reduced, and the service life of the mechanism is prolonged. The guide assembly 720 also increases the stability and reliability of the jacking mechanism 7, ensuring that there is no deviation or shaking during lifting.

[0114] As shown in FIG. 10, in some embodiments of the present application, the liquid collecting assembly 90 comprises a first connecting plate 902, a conveying outer plate 903, and a conveying inner plate 904. The first connecting plate 902 is connected to the moving plate 601, the conveying outer plate 903 is in sliding connection with the first connecting plate 902 and can move relative to the first connecting plate 902 in the second direction Y. The conveying inner plate 904 is in sliding connection with the conveying outer plate 903, the conveying inner plate 904 can move relative to the conveying outer plate 903 in the second direction Y, and the liquid collecting plate 901 is connected to the conveying inner plate 904.

[0115] In the above structure, the first connecting plate 902 serves as the base of the moving plate 601, providing the moving ability of the whole mechanism. The conveying outer plate 903 is in sliding connection with the first connecting plate 902 and moves the first connecting plate 902 along the second direction Y to adapt to the battery cell 50 at different positions. The conveying inner plate 904 is in sliding connection with the conveying outer plate 903, further enhancing the flexibility of the mechanism, ensuring that the collecting plate 901 can be accurately positioned at the leakage point. The collecting plate 901 is connected to the conveying inner plate 904, and when the mechanism moves above the battery cell 50, the collecting plate 901 can effectively collect the leaked electrolyte, avoiding damage to the battery cell 50 and the surrounding environment.

[0116] In some alternative embodiments, a material resistant to corrosion and electrolyte erosion can be selected to manufacture the collecting plate 901, so that it can obtain stability and reliability for long-term use. The conveying outer plate 903 and the conveying inner plate 904 can also consider using lightweight but high-strength materials to reduce the overall weight and improve response speed.

[0117] In some alternative embodiments, an electrolyte detection sensor is integrated on the collecting plate 901 to monitor the leakage in real time and automatically trigger the movement of the mechanism.

[0118] For example, the size and shape of the collecting plate 901 can be matched with the battery cell 50, i.e., it should completely cover the battery cell 50 on the telescopic assembly to improve the protection performance of the battery cell 50. In addition, drainage holes can be provided on the collecting plate 901, which can be connected to the drainage pipeline.

[0119] In some alternative embodiments, the first connecting plate 902, the conveying outer plate 903, and the conveying inner plate 904 form a collecting assembly 90, the number of collecting assemblies 90 is two, and the two collecting assemblies 90 are arranged at intervals along the first direction X. The number of collecting plates 901 is one, and the two collecting assemblies 90 are connected to the two sides of the collecting plate 901. The above structure can improve the stability of the movement of the collecting plate 901.

[0120] As shown in FIG. 11, in some embodiments of the present application, the collecting mechanism 9 further includes a collecting drive motor 905, a third gear 906, and a first rack 907. The third gear 906 is connected to the collecting drive motor 905 and rotates under the drive of the collecting drive motor 905. The first rack 907 is in engagement with the third gear 906, and the first rack 907 is arranged on the side of the conveying outer plate 903 facing the first connecting plate 902.

[0121] The collecting drive motor 905 is the power source of the whole moving mechanism 6, which can start, stop, or change the speed under the action of the control signal, thereby driving the rotation of the third gear 906. The third gear 906 is connected to the output shaft of the collecting drive motor 905, and when the motor rotates, the third gear 906 also rotates synchronously.

[0122] The first rack 907 is fixed to one side of the conveying outer plate 903 facing the first connecting plate 902, and is engaged with the third gear 906. When the third gear 906 rotates, the first rack 907 will be driven to move along its length direction (i.e. the second direction Y) due to the engagement between the gear 808 and the rack. The conveying outer plate 903 is driven to move along the second direction Y by the first rack 907, and the conveying inner plate 904 can also move along the second direction Y correspondingly due to the sliding connection with the conveying outer plate 903. Finally, this movement will drive the collecting plate 901 to reach above the battery cell 50 to collect the leaked electrolyte.

[0123] In the above structure, the moving efficiency of the collecting mechanism 9 and the accuracy of the moving position can be improved, and the damage of the leaked electrolyte to the battery cell 50 can be reduced, thereby improving the yield of the battery cell 50.

[0124] In some optional embodiments, the collecting mechanism 9 further comprises a first driving motor, an inner plate gear 808 and an inner plate rack. The inner plate gear 808 is connected to the first driving motor and rotates under the driving of the first driving motor. The inner plate rack is connected to the conveying inner plate 904, and the inner plate rack is engaged with the inner plate gear 808.

[0125] In the above structure, the first driving motor drives the conveying inner plate 904 to move relative to the conveying outer plate 903, which cooperates with the collecting driving motor 905, the third gear 906 and the first rack 907, so as to increase the moving distance of the collecting mechanism 9 and expand the collecting range of the collecting plate 901.

[0126] As shown in FIG. 12, in some embodiments of the present application, the telescopic mechanism 8 comprises a second connecting plate 801, a conveying lower plate 802 and a conveying upper plate 803. The second connecting plate 801 is connected to the jacking mechanism 7, the conveying lower plate 802 is slidingly connected with the second connecting plate 801 and can move along the second direction Y relative to the second connecting plate 801. The conveying upper plate 803 is slidingly connected with the conveying lower plate 802, and the conveying upper plate 803 can move along the second direction Y relative to the conveying lower plate 802. The conveying upper plate 803 is used for carrying the carried object.

[0127] For example, the jacking mechanism 7 is provided with a first mounting plate 723, and the second connecting plate 801 is connected with a second mounting plate 804. The second mounting plate 804 and the first mounting plate 723 can be connected by welding or fasteners, so as to mount the telescopic mechanism 8 to the jacking mechanism 7.

[0128] In the above structure, the sliding connection and relative movement of the conveying lower plate 802 and the conveying upper plate 803 can improve the accuracy of the carried object (battery cell 50). The design of the telescopic mechanism 8 allows quick and accurate adjustment of the position, thus improving the carrying efficiency of the battery cell 50. By adjusting the relative position of the conveying lower plate 802 and the conveying upper plate 803, different sizes and shapes of battery cells 50 can be accommodated, increasing the flexibility and versatility of the equipment.

[0129] The operator only needs to control the actions of the jacking mechanism 7 and the telescopic mechanism 8 to achieve accurate positioning and carrying of the battery cell 50, reducing the difficulty and labor intensity of operation. The telescopic mechanism 8 has a reasonable and compact structure design, which can ensure the stability and reliability of the equipment during high-speed and continuous operation.

[0130] As shown in FIG. 13 and FIG. 14, in some embodiments of the present application, the telescopic mechanism 8 further comprises a second driving assembly, which comprises a telescopic driving motor 805, a fourth gear 806 and a second rack 807. The fourth gear 806 is connected to the telescopic driving motor 805 and rotates under the drive of the telescopic driving motor 805. The second rack 807 is engaged with the fourth gear 806, and the second rack 807 is arranged on the side of the conveying lower plate 802 facing the second connecting plate 801.

[0131] In some optional embodiments, the telescopic mechanism 8 further comprises a plurality of gears 808 arranged in sequence on the second connecting plate 801, the first gear 808 of the plurality of gears 808 is engaged with the fourth gear 806, and adjacent two gears 808 are engaged with each other. The plurality of gears 808 rotates under the drive of the fourth gear 806, and the racks are respectively engaged with the plurality of gears 808 and moved under the rotation of the gears 808.

[0132] In the above structure, the telescopic driving motor 805 serves as a power source to provide power for the movement of the telescopic mechanism 8. The fourth gear 806 is connected to the output shaft of the telescopic driving motor 805, and when the motor rotates, the fourth gear 806 also rotates synchronously. The second rack 807 is fixed to the side of the conveying lower plate 802 facing the second connecting plate 801 and engaged with the fourth gear 806. When the fourth gear 806 rotates, the conveying lower plate 802 is driven to move along the second direction Y through the engagement relationship between the gears 808 and the racks.

[0133] The automatic movement of the conveying lower plate 802 in the second direction Y is realized through the cooperation of the telescopic driving motor 805, the fourth gear 806 and the second rack 807, and the degree of automation of the telescopic mechanism 8 is improved. By accurately controlling the rotation angle and speed of the telescopic driving motor 805, the precise positioning of the conveying lower plate 802 (and the battery monomer 50 carried thereon) can be realized, so that the battery monomer 50 can be accurately moved below the liquid injection nozzle of the liquid injection device.

[0134] In some optional embodiments, the telescopic mechanism 8 can realize movement with different speeds and distances by adjusting the parameters (such as rotation speed, rotation angle, etc.) of the telescopic driving motor 805 according to the actual needs of the production line, and has strong flexibility. Since the gear 808 and the rack are adopted for transmission, the structure has high transmission efficiency and stability, and can maintain high performance in the case of long-time continuous work.

[0135] In some embodiments of the present application, the telescopic mechanism 8 further comprises a sliding wheel 809, which is arranged on the second connecting plate 801 and can rotate relative to the second connecting plate 801; the side of the conveying lower plate 802 facing the second connecting plate 801 is provided with a sliding groove 810, and the sliding groove 810 cooperates with the sliding wheel 809 to realize the sliding connection between the conveying lower plate 802 and the second connecting plate 801.

[0136] In the above structure, the sliding wheel 809 and the sliding groove 810 are designed, so that the frictional force acting on the conveying lower plate 802 during movement is greatly reduced, thereby improving the movement efficiency. The telescopic mechanism 8 can quickly and accurately adjust the position of the battery monomer 50, thereby improving the overall efficiency of the production line. The cooperation of the sliding wheel 809 and the sliding groove 810 makes the movement path of the conveying lower plate 802 more accurate, and the battery monomer 50 can be more accurately moved below the liquid injection nozzle of the liquid injection device, thereby avoiding inaccurate or waste liquid injection due to position deviation. Since the frictional force is reduced, the wear between the conveying lower plate 802 and the second connecting plate 801 is also reduced, thereby prolonging the service life of the equipment.

[0137] In some embodiments of the present application, the number of liquid collecting assemblies 90 is two, and the two liquid collecting assemblies 90 are arranged at intervals along the first direction X, and the telescopic mechanism 8 is arranged between the two liquid collecting assemblies 90. The above structure reduces the interference between the liquid collecting mechanism 9 and the telescopic mechanism 8, and the two mechanisms can move relatively independently, thereby improving the working efficiency of the battery monomer 50 liquid injection and liquid leakage prevention.

[0138] As shown in FIG. 4, in some embodiments of the present application, the moving mechanism 6 further comprises a base 602, a slide rail 603, and a slide block. The slide rail 603 is arranged on the base 602, and extends along the first direction X. The slide block has a groove matched with the slide rail 603, and is slidably connected with the slide rail 603 through the groove. The moving plate 601 is connected to a side of the slide block away from the slide rail 603. The above structure limits the moving path of the moving mechanism 6 by arranging the slide rail 603 and the slide block, reduces the friction between the moving plate 601 and the base 602, and improves the moving efficiency.

[0139] In some optional embodiments, the moving mechanism 6 further comprises a moving drive motor, a moving gear 808, and a moving rack. The moving drive motor is arranged on the moving plate 601. The moving gear 808 is connected to the moving drive motor. The moving rack is arranged on the base 602, and extends along the first direction X. The moving drive motor drives the moving gear 808 to rotate, and moves along the moving rack to drive the moving plate 601 to move along the first direction X.
