[0003] Currently, AGVs (Automated Guided Vehicles) are generally used to move pallet-supporting vehicles to various workstations for the assembly of battery components. This results in some workstations requiring a large number of AGVs to move the pallet-supporting vehicles, leading to higher costs. Utility Model Content

[0051] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0053] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0054] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0055] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0056] In the description of the embodiments of this application, the term "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces). "Several" means one or more, unless otherwise explicitly specified.

[0057] In the description of the embodiments of this application, the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0058] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

For example, among three components A1, A2, and B, the distance between A1 and B is greater than the distance between A2 and B. Therefore, A2 is closer to B than A1, meaning A2 is adjacent to B, or B is adjacent to A2. Similarly, when there are multiple components C, namely C1, C2, ..., C... N If one of the C components, such as C2, is closer to the B component than the other C components, then B is adjacent to C2, or C2 is adjacent to B.

[0061] A battery assembly typically includes a housing, individual battery cells housed within the housing, and busbars connecting the battery cells. These components are assembled into the housing, and a cover is then installed to form the battery assembly. Therefore, battery assembly manufacturing requires multiple processes, performed at different workstations. To minimize housing deformation during assembly, the battery assembly is often placed on a pallet. Currently, pallet trolleys are commonly used to move the pallets to each workstation for assembling the battery assembly components. However, because pallet trolleys are relatively simple in structure and lack power, AGVs (Automated Guided Vehicles) are used to guide them to each workstation for battery assembly. However, using AGVs to move pallet trolleys between workstations requires a large number of AGVs, resulting in high costs.

[0062] Based on the above considerations, to address the issue of high costs associated with using numerous AGV vehicles to tow carriers in related technologies, this application provides a traction device. This device involves installing a traction structure on a traction line, supporting the traction line with multiple rotating shafts, and using a drive mechanism to rotate the traction line in a first direction. This, in turn, causes the traction structure to rotate in the same direction. In use, this allows the carrier to move along the first direction. Especially when multiple workstations are arranged along the first direction, the traction device can guide the carrier through these workstations sequentially. The structure is simple and low-cost. Furthermore, using the traction structure on the traction line to move the carrier only requires moving the carrier to one end of the traction line, and the carrier can be easily pushed out at the end of the traction line, facilitating easy entry and exit and increasing efficiency. Moreover, using the traction line to move the carrier facilitates easy positioning of the carrier, allowing for accurate location of its movement.

[0063] The linear module mentioned in the embodiments of this application is also called a linear drive module; a linear module refers to a device, component, module, or mechanism that can drive structural parts to move linearly. A linear drive module can be a linear module, a lead screw and nut mechanism, a gear and rack mechanism, a cylinder, a hydraulic cylinder, etc. When using the linear drive module mentioned in the embodiments of this application, it can be any one of a linear module, a lead screw and nut mechanism, a gear and rack mechanism, a cylinder, or a hydraulic cylinder, and can be specifically configured and used as needed.

[0064] The linear module mentioned in the embodiments of this application is also known as a linear module, linear slide, etc. Currently, widely used linear modules can be divided into: synchronous belt type, ball screw type, and linear motor type. When the linear drive module mentioned in the embodiments of this application uses a linear module, any one of the synchronous belt type linear module, ball screw type linear module, and linear motor type linear module can be used, and the specific settings and uses can be made according to needs.

[0065] Synchronous belt type linear modules mainly include belts, linear guides, couplings, and motors. The working principle of the synchronous belt type is as follows: the belt is installed on the drive shafts on both sides of the linear module, one of which is connected to the motor as a power input shaft; a slider for connecting the workpiece is fixed on the belt. When the drive shaft rotates, it drives the belt to move, which in turn drives the slider to move linearly.

[0066] The ball screw type linear module mainly includes a ball screw, linear guide, ball screw support, motor, etc.

[0067] A ball screw is a product that converts rotary motion into linear motion, or vice versa. A ball screw mainly consists of a screw and a nut. The screw is a rod-shaped structure with external threads. The nut is a structure with internal threads. The external threads of the screw and the internal threads of the nut mate to allow the nut to be mounted on the screw. Rotation of the screw causes the nut to move along it, thus converting rotary motion into linear motion. Connecting the workpiece to the nut allows the workpiece to move linearly as the nut moves. Some ball screws also include balls, which primarily reduce the frictional resistance between the nut and the screw.

[0068] Linear guides, also known as slide rails, linear guides, or linear slide rails, are used in linear reciprocating motion applications. They can withstand a certain amount of torque and achieve high-precision linear motion under high loads.

[0069] A linear motor module, also known as a linear motor, is a transmission device that directly converts electrical energy into linear motion mechanical energy without the need for any intermediate conversion mechanism.

[0070] The lead screw and nut mechanism mainly consists of a lead screw, a nut, and a motor. The nut is mounted on the lead screw, which is connected to the motor. The motor drives the lead screw to rotate, thus pushing the nut to move along the lead screw, achieving linear movement of the nut. When the workpiece is connected to the nut, the linear movement of the nut can drive the workpiece to move linearly as well.

[0071] A gear and rack mechanism mainly consists of a gear, a rack, and a motor. The gear meshes with the rack, and the gear is connected to the motor. The motor drives the gear to rotate, which in turn propels the rack to move linearly. When a workpiece is connected to the rack, the linear movement of the rack can drive the workpiece to move linearly as well. A rack is a component with multiple teeth evenly distributed along its length. A gear is a wheel-shaped component with multiple teeth evenly distributed on its outer circumference.

[0072] A cylinder is a mechanical component that guides a piston to perform linear reciprocating motion within the cylinder. A cylinder mainly includes a cylinder barrel, end caps, a piston, a piston rod, and seals. The end cap covers the end of the cylinder barrel, the piston rod is connected to the piston, and the piston is slidably mounted within the cylinder barrel. The piston rod extends out of the cylinder barrel through the end cap, and the seals seal the area between the piston rod and the end cap. It works by filling the cylinder barrel with high-pressure gas to one side of the piston, thus pushing the piston to move linearly within the cylinder barrel, which in turn pushes the piston rod to move linearly along the cylinder barrel. When the workpiece is connected to the piston rod, the linear movement of the piston rod causes the workpiece to move linearly as well.

[0073] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy to perform linear reciprocating motion (or oscillating motion). A hydraulic cylinder generally includes a cylinder barrel, cylinder head, piston, piston rod, and sealing devices. The cylinder head covers the end of the cylinder barrel, the piston rod is connected to the piston, the piston is slidably mounted in the cylinder barrel, and the piston rod extends out of the cylinder barrel through the cylinder head. Seals seal the piston rod and cylinder head. It primarily works by filling the cylinder barrel with high-pressure fluid to one side of the piston, pushing the piston to move linearly within the cylinder barrel, which in turn pushes the piston rod to move linearly along the cylinder barrel. When the workpiece is connected to the piston rod, the linear movement of the piston rod drives the workpiece to move linearly.

[0074] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. This application does not have any particular limitations.

[0083] As an example, the housing 10 may include a main body 11 and a cover 12, with the cover 12 covering the main body 11 to form a closed space inside the housing 10 for housing the battery cells 21. Here, "closed" refers to covering or shutting off; it can be sealed or unsealed. The main body 11 is a shell structure with an open-sided receiving space inside.

[0084] As an example, the housing 10 may include a first housing and a second housing. The first housing and the second housing are fastened together to form a closed space inside the housing 10 to house the battery cell assembly 20. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first housing may be a cover 12 or a base plate 112.

[0085] Please see Figure 1 Each battery cell 21 has a length, width, and height, with the length being greater than or equal to its width. The height of the battery cell 21 can be parallel to the depth direction of the accommodating space of the housing body 11; that is, the height direction of the battery cell 21 is parallel to the height direction Z of the housing body 10. As an example, the length direction of the battery cell 21 can be parallel to the length direction X of the housing body 10. As an example, the length direction of the battery cell 21 can be parallel to the width direction Y of the housing body 10. As an example, the length direction of the battery cell 21 can be tilted relative to the length direction X of the housing body 10.

[0086] In some embodiments, please refer to Figure 1 The battery cell assembly 20 comprises a plurality of battery cells 21 arranged along a third direction K. In some embodiments, the battery cell 21 has a height, a length, and a width, wherein the length of the battery cell 21 is greater than or equal to the width of the battery cell 21. As an example, the length direction of the battery cell 21 may be aligned with the third direction K, and in this case, the side of the battery cell 21 with the largest area is parallel to the third direction K. As an example, the length direction of the battery cell 21 may be perpendicular to the third direction K, and in this case, the side of the battery cell 21 with the largest area is perpendicular to the third direction K.

[0087] In some embodiments, the housing 10 includes a limiting beam 13, which is installed inside the housing 10 to increase the structural strength of the housing 10 and can also be used to support the battery cell 21 to limit the expansion deformation of the battery cell 21.

[0088] In some embodiments, the housing 10 includes a mounting beam 14, which is fixedly connected to the frame 111 and is used to connect an external device using the battery device 100 to support the battery device 100 on the device.

[0089] Please see Figures 1 to 8 According to some embodiments of this application, a traction device 400 is provided, including a traction structure 45, a traction line 42, multiple rotating shafts 43, a bracket 41, and a drive mechanism 44. The traction structure 45 is used to drive a carrier 31 to move along a first direction M; the traction line 42 supports the traction structure 45 and is used to drive the traction structure 45 to rotate along the first direction M; the multiple rotating shafts 43 cooperate to support the traction line 42; each rotating shaft 43 is rotatably mounted on the bracket 41; the drive mechanism 44 is used to drive the traction line 42 to rotate along the first direction M.

[0090] The traction structure 45 refers to a structure that can move the carrier 31. As an example, the traction structure 45 can use structural components such as rods or plates.

[0091] The support vehicle 31 refers to the movable vehicle structure used to support the main body of the battery device 100 during the assembly process, on which other components of the battery device 100 are assembled. As an example, rollers can be installed at the bottom of the frame structure to form the support vehicle 31, resulting in a simple and low-cost structure. As an example, the support vehicle 31 can also adopt other structures, such as installing rollers at the bottom of a plate to form the support vehicle 31. As an example, to facilitate the support vehicle 31 in supporting the battery device 100, a tray 311 can also be provided on the support vehicle 31 for assembling the various components of the battery device 100 on the tray 311. In particular, using the tray 311 to support the main body of the battery device 100 can reduce deformation of the main body. The tray 311 refers to a plate-shaped frame structure used to support the battery device 100. As an example, the tray 311 can be fixed to the support vehicle 31, meaning the tray 311 is part of the support vehicle 31, allowing the battery device 100 to be assembled directly on the support vehicle 31. As an example, the tray 311 can also be detachably placed on the carrier 31 so that the tray 311 can be moved during the assembly of the battery device 100, thereby moving the components of the battery device 100 assembled on the tray 311.

[0092] The traction line 42 refers to a flexible structure arranged in a loop. As an example, the traction line 42 can be a structure formed by connecting multiple strips, such as a belt, a chain, or a belt.

[0095] Support 41 refers to the structure used to support the rotating shaft 43. Support 41 can be formed by combining beams, columns, rods, plates, etc. Support 41 can be made of steel, aluminum, plastic, wood, etc.

[0096] The drive mechanism 44 refers to the structure used to drive the traction line 42 to move. As an example, the drive mechanism 44 can be a rotary mechanism that drives the rotating shaft 43 to rotate, thereby moving the traction line 42. As an example, the rotary mechanism can be a motor. As an example, the rotary mechanism can also be a combination of a motor and a reducer. As an example, the rotary mechanism can be a rotary cylinder. As an example, the drive mechanism 44 can be a linear module that pushes a portion of the traction line 42 to move along a first direction M, thereby causing the traction line 42 to rotate along the first direction M.

[0097] The traction line 42 supporting the traction structure 45 means that the traction structure 45 is installed on the traction line 42, and the traction line 42 supports the traction structure 45.

[0098] Multiple pivots 43 cooperate to support the traction line 42, meaning that the pivots 43 extend into the loop-shaped traction line 42, and the pivots 43 at both ends move away from each other in the first direction M, causing the traction line 42 to extend in the first direction M and to open up the traction line 42. When there are more than two pivots 43, the remaining pivots 43 can abut against the traction line 42, making the traction line 42 taut to hold each pivot 43 in place.

[0099] The rotational movement of the traction line 42 along the first direction M means that the part of the traction line 42 above the rotating shaft 43 moves parallel to the first direction M and in the positive direction, while the part of the traction line 42 below the rotating shaft 43 moves parallel to the first direction M and in the opposite direction.

For ease of description, the portion of the traction line 42 located above the pivot 43 is simply referred to as the portion of the traction line 42 located above the pivot 43.

[0102] The portion of the traction line 42 located below the pivot 43 refers to the section of the traction line 42 that lies below the pivot 43 along the height direction Z when the traction line 42 is extended. For ease of description, the portion of the traction line 42 located below the pivot 43 is simply referred to as the lower portion of the traction line 42.

[0103] The drive mechanism 44 is used to drive the traction line 42 to rotate and move in the first direction M. This can drive the traction structure 45 on the traction line 42 to rotate and move in the first direction M. When the carrier 31 reaches one end of the open traction line 42, the traction line 42 drives the traction structure 45 to rotate from one end of the traction line 42 to the upper part of the traction line 42. During this process, the traction structure 45 can gradually come into contact with the carrier 31 to push the carrier 31 to move in the first direction M. This allows the carrier 31 to pass through multiple workstations set in the first direction M in sequence so that the battery device 100 can be assembled on the carrier 31. When the traction structure 45 reaches the end of the traction line 42 and rotates to the lower part of the traction line 42, it gradually disengages from the carrier 31. Therefore, by simply moving the carrier 31 to one end of the traction line 42, the traction structure 45 can drive the carrier 31 to move along the first direction M. At the other end of the traction line 42, the carrier 31 can also be easily pushed out, facilitating its entry and exit. Compared to the approximately 25-second start-stop time required by the AGV 32, using the traction device 400 to move the carrier 31 to and from the corresponding workstation is more efficient. Using the traction line 42 to move the carrier 31 facilitates its positioning. Compared to using the AGV 32 entirely, especially when moving the carrier 31 carrying the battery device 100, which is prone to slippage due to the weight and inertia of the battery device 100, using the traction line 42 allows for accurate positioning of the carrier 31. Furthermore, since the traction line 42 can pass through multiple workstations, the carrier 31 can pass through these workstations sequentially without the need for the AGV 32, reducing costs. In addition, the AGV vehicle 32 can be used to dispatch the carrier 31 to the traction device 400, and the AGV vehicle 32 can be used to pull away the carrier 31 that has been moved out of the traction device 400, which can achieve more flexible dispatching and reduce the cost by using fewer AGV vehicles 32.

[0104] In the technical solution of this application embodiment, a traction structure 45 is installed on the traction line 42, and multiple rotating shafts 43 are used to support the traction line 42. A drive mechanism 44 is used to drive the traction line 42 to rotate and move in the first direction M, thereby driving the traction structure 45 to rotate and move in the first direction M. Thus, when the support vehicle 31 moves to one end of the traction line 42, it can be driven by the traction structure 45 to move in the first direction M. Moreover, depending on the length of the traction line 42, the support vehicle 31 can be driven to pass through multiple processing stations of battery devices 100 so that battery devices 100 can be assembled on the support vehicle 31. This traction device 400 has a simple structure and low cost.

[0105] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 8The traction structure 45 includes a push assembly 452 for supporting the vehicle 31 and a connecting seat 451 for supporting the push assembly 452, the connecting seat 451 being mounted on the traction line 42.

[0106] Connector 451 refers to a seat structure adapted to connect to traction line 42. Connector 451 is provided to facilitate connection to traction line 42, thereby allowing the push assembly 452 to be mounted on traction line 42. As an example, connector 451 can be formed by combining plates, rods, blocks, etc. As an example, connector 451 can be a one-piece structure, manufactured by methods such as casting, forging, or injection molding. Connector 451 can be made of materials such as plastic, metal, or ceramic.

[0107] The pushing assembly 452 refers to the structure used to push the support carriage 31. As an example, the pushing assembly 452 can use a guide rod with a buffer pad on it. The guide rod is mounted on the connecting seat 451, and the buffer pad contacts the support carriage 31 to reduce wear on it. As another example, the pushing assembly 452 can use a push block with a locating pin on it. The support carriage 31 has a locating hole, into which the locating pin is inserted to position the support carriage 31, and the push block then pushes the support carriage 31 to move.

[0108] The above technical solution provides a push component 452 to move the support vehicle 31; and a connecting seat 451 to facilitate connection with the traction line 42, thereby installing the push component 452 on the traction line 42 for easy assembly.

[0109] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 8 The pushing component 452 includes a guide wheel 4521 for pushing the support vehicle 31 and a support 4522 for supporting the guide wheel 4521, the support 4522 being mounted on the connecting seat 451.

[0110] Guide wheel 4521 refers to the wheel structure used to push the support carriage 31. Guide wheel 4521 can be made of materials such as plastic, rubber, or silicone to reduce wear on the support carriage 31 when pushing it, thus protecting the support carriage 31. Guide wheel 4521 can also be made of materials such as metal or ceramic. Guide wheel 4521 can also be a combination structure using a rigid material for support and a soft material for surrounding wrapping. The rigid material can be metal, ceramic, etc., and the soft material can be rubber, silicone, etc.

[0111] Support 4522 refers to the seat structure adapted to support guide wheel 4521. Support 4522 is provided to facilitate connection with connecting seat 451, thereby mounting guide wheel 4521 on connecting seat 451 and supporting it on traction line 42. As an example, support 4522 can be formed by combining plates, rods, blocks, etc. As an example, support 4522 can be a one-piece molded structure, such as cast, forged, or injection molded. Support 4522 can be made of materials such as plastic, metal, or ceramic.

[0112] Through the above technical solution, a support 4522 is set so as to rotate the support guide wheel 4521 and support the guide rail on the connecting seat 451; the guide wheel 4521 is set and pushes the support vehicle 31 through the guide wheel 4521. When in contact with the support vehicle 31, it can play a good guiding role and reduce wear between the guide wheel and the support vehicle 31, thus providing good protection for the support vehicle 31.

[0113] In some embodiments, please refer to Figures 2 to 4 and Figure 8 Multiple traction structures 45 are provided, and multiple traction structures 45 are installed at intervals on the traction line 42.

[0114] The term "multiple traction structures 45" means that there can be two, three, four, five, six, seven, or even more traction structures 45, which can be set according to the specific needs.

[0115] Through the above technical solution, multiple traction structures 45 are set on the traction line 42 so that the traction device 400 can simultaneously drive multiple carrier vehicles 31 to move, thereby further reducing costs and improving efficiency.

[0116] In some embodiments, please refer to Figures 2 to 4 and Figure 8 Multiple traction structures 45 are equally spaced on the traction line 42.

[0117] The multiple traction structures 45 are equally spaced on the traction line 42, which means that the distance between any two adjacent traction structures 45 on the traction line 42 along the rotation direction of the traction line 42 is equal. That is, the distance between any two adjacent traction structures 45 on the upper part of the traction line 42 is equal, and the distance between any two adjacent traction structures 45 on the lower part of the traction line 42 is equal.

[0118] With the above technical solution, multiple traction structures 45 are equally spaced, which makes it easy to determine the position of the traction vehicle 31 when it is being moved, thus facilitating the positioning of the traction vehicle 31.

[0119] In some embodiments, please refer to Figures 2 to 4 and Figure 8There are multiple traction lines 42, which are spaced apart along the second direction N. The traction structure 45 is connected to each traction line 42, and the rotating shaft 43 is connected to each traction line 42. The second direction N is perpendicular to the first direction M.

[0120] Multiple roots refer to two or more roots.

[0121] Multiple traction lines 42 are spaced apart along the second direction N, meaning that adjacent traction lines 42 are spaced apart along the second direction N.

[0122] By arranging multiple traction lines 42 at intervals along the second direction N, the width of the transmission line formed by the multiple traction lines 42 as a whole can be increased, so as to more stably support the traction structure 45.

[0123] The rotating shaft 43 is connected to each traction line 42 to support each traction line 42, and to open and tighten each traction line 42 so that multiple traction lines 42 cooperate to support the traction structure 45 and drive the traction structure 45 to move.

[0124] By using the above technical solution, multiple traction lines 42 can be set up to stably support the traction structure 45 and drive the traction structure 45 to move smoothly, thereby driving the support vehicle 31 to move smoothly.

[0125] In some embodiments, when the traction line 42 is made of multiple plates hinged together, the overall width of the traction line 42 can be controlled by controlling the width of the plates to cooperate with the stable support of the traction structure 45.

[0126] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 8 The traction line 42 includes a chain 421, and a sprocket 433 adapted to connect the chain 421 is provided on the shaft 43.

[0127] Chain 421 refers to a loop-shaped structural component made using chain 421. Chain 421 is an assembly of several rigid components connected by hinges, used to transmit motion and power. Structurally, chain 421 generally consists of chain links, pins, rollers, etc., with adjacent chain links hinged by pins to form a flexible rotating connection.

[0128] A sprocket 433 refers to a structure with teeth on its circumference. The teeth on the sprocket 433 mesh with the links of the chain 421, driving the chain 421 to move and realizing the transmission of power and motion. The sprocket 433 can be made of materials such as metal, ceramic, and plastic.

[0129] Through the above technical solution, the traction line 42 uses a chain 421, which has a simple structure and allows for convenient and accurate control of its moving speed and position, thereby controlling the moving speed and position of the traction structure 45 and the supporting vehicle 31 it pushes.

[0130] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 8 The drive mechanism 44 includes a motor 441, which is connected to a rotating shaft 43.

[0131] Motor 441 refers to an electromagnetic device that uses the law of electromagnetic induction to convert or transmit electrical energy.

[0132] The above technical solution uses a motor 441 to drive a rotating shaft 43 to rotate, thereby driving the chain 421 to rotate and move. The structure is simple and the position of the motor 441 is easy to set, which facilitates the installation layout.

[0133] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 8 The drive mechanism 44 also includes a reducer 442. The motor 441 is connected to the reducer 442. The reducer 442 is connected to a rotating shaft 43 to increase the transmission torque so as to better drive the traction line 42 to move smoothly via the rotating shaft 43.

[0134] In some embodiments, please refer to Figures 2 to 4 and Figure 8 The multiple rotating shafts 43 include a drive shaft 432 and multiple driven shafts 431. The multiple driven shafts 431 cooperate to support the chain 421. The sprocket 433 on the drive shaft 432 is connected to the part of the chain 421 located on the upper side of the driven shaft 431 in the height direction Z. The drive shaft 432 is connected to the motor 441.

[0135] The drive shaft 432 refers to the shaft 43 used to drive the chain 421 to move.

[0136] Driven shaft 431 refers to the shaft 43 used to support chain 421.

[0137] Multiple driven shafts 431 cooperate to support the chain 421, allowing the chain 421 to be spread using the driven shafts 431. As an example, the chain 421 can be connected via a sprocket 433 on the driven shaft 431, and the driven shafts 431 on both sides can be moved away from each other along a first direction M to spread the chain 421, thereby supporting it. As an example, when there are more than two driven shafts 431, the remaining driven shafts 431 can support the upper portion of the chain 421, thus ensuring greater stability in the upper portion and allowing the traction structure 45 on the upper portion of the chain 421 to smoothly move the carrier 31.

[0138] The connection between the sprocket 433 on the drive shaft 432 and the upper part of the chain 421 in the height direction Z of the driven shaft 431 means that the sprocket 433 on the drive shaft 432 is connected to the upper part of the chain 421 so as to drive the upper part of the chain 421 to move along the first direction M, thereby enabling the traction structure 45 on the upper part of the chain 421 to drive the support vehicle 31 to move smoothly.

[0139] The above technical solution uses multiple driven shafts 431 to support the chain 421, which facilitates the assembly of the chain 421; while the sprocket 433 on the drive shaft 432 is connected to the upper part of the chain 421 so as to drive the chain 421 to move, and the position of the drive shaft 432 can be conveniently arranged.

[0140] In some embodiments, the plurality of rotating shafts 43 include a drive shaft 432 and a driven shaft 431, which can cooperate to support and open the chain 421, such that the drive shaft 432 and a driven shaft 431 are located at the two ends of the open chain 421 along the first direction M.

[0141] In some embodiments, please refer to Figures 2 to 4 and Figure 8 The bracket 41 includes a base plate 412 and support seats 411 that support each rotating shaft 43 respectively. The base plate 412 extends along the first direction M, and each support seat 411 is mounted on the base plate 412.

[0142] The substrate 412 refers to the plate structure that serves as the mounting reference. The substrate 412 can be made of metal materials such as steel or aluminum alloy to ensure proper positioning of the support base 411. The substrate 412 can also be made of materials such as plastic, ceramic, or fiber.

[0143] The substrate 412 is extended along the first direction M, which means that the direction in which the length of the substrate 412 is located is parallel to the first direction M.

[0144] Support base 411 refers to the seat structure used to support the rotating shaft 43. As an example, support base 411 can be formed by combining plates, rods, blocks, etc. As an example, support base 411 can be a one-piece molded structure, such as cast, forged, or injection molded. Support base 411 can be made of materials such as plastic, metal, or ceramic.

[0145] A support base 411 is provided to support the corresponding rotating shaft 43 and facilitate the rotation of the rotating shaft 43 on the support base 411. The support base 411 also facilitates connection to the base plate 412. The base plate 412 facilitates the positioning of the support base 411, and consequently, the positioning of the rotating shaft 43 and its supported traction line 42. Furthermore, the base plate 412 facilitates connection to the mounting base of the traction device 400, thereby facilitating the assembly and use of the traction device 400.

[0146] Through the above technical solution, a base plate 412 is set up to position and assemble the support base 411, thereby supporting each rotating shaft 43, so that multiple rotating shafts 43 cooperate to support the traction line 42.

[0147] In some embodiments, the support 41 may also use a bench structure to directly support the multiple rotating shafts 43.

[0148] In some embodiments, the bracket 41 may also use only a plurality of support seats 411 to support the rotating shaft 43.

[0149] Please see Figures 2 to 8According to some embodiments of this application, a traction device 400 is provided, including a traction structure 45, a traction line 42, multiple rotating shafts 43, a bracket 41, and a drive mechanism 44. Multiple traction structures 45 are provided, and the multiple traction structures 45 are equally spaced on the traction line 42. Multiple traction lines 42 are provided, spaced apart along a second direction N. The traction structures 45 are connected to each traction line 42, and the rotating shafts 43 are connected to each traction line 42. The second direction N is perpendicular to the first direction M. The traction structure 45 includes a pushing component 452 and a connecting seat 451. The pushing component 452 includes a guide wheel 4521 for pushing a support vehicle 31 and a support 4522 for supporting the guide wheel 4521. The support 4522 is mounted on the connecting seat 451. The connecting seat 451 is mounted on the traction line 42. The drive mechanism 44 includes a motor 441. The traction line 42 includes a chain 421, and a sprocket 43 is provided on a rotating shaft 43 to connect the chain 421. Multiple rotating shafts 43 include a drive shaft 432 and multiple driven shafts 431. The driven shafts 431 cooperate to support the chain 421. The sprocket 433 on the drive shaft 432 is connected to the portion of the chain 421 located above the driven shaft 431 in the height direction Z. The drive shaft 432 is connected to a motor 441. The motor 441 drives the drive shaft 432 to rotate, thereby causing the chain 421 to rotate and move in a first direction M, which in turn causes the traction structure 45 to rotate and move in the first direction M, thereby causing the carrier 31 to move in the first direction M, so that the carrier 31 passes through multiple processing stations of battery devices 100 for assembly of battery devices 100 on the carrier 31. This traction device 400 has a simple structure and low cost.

[0150] Please see Figures 5 to 8 According to some embodiments of this application, this application provides a battery production equipment 300, including a support vehicle 31 and a traction device 400 as described in the above embodiments. The traction device 400 is used to drive the support vehicle 31 to move along a first direction M. Using the traction device 400 to drive the support vehicle 31 to move results in a simple structure and low cost.

[0151] In some embodiments, the battery production equipment 300 includes an AGV vehicle 32, which is used to drive the carrier vehicle 31 to the traction device 400.

[0152] AGV (Automated Guided Vehicle) 32 is an automated device that can autonomously drive along a specified path or environment according to a preset program or real-time instructions without human driver, and complete tasks such as material handling and transportation.

[0153] The above technical solution involves setting up an AGV vehicle 32 to transport the carrier vehicle 31, so as to supply the carrier vehicle 31 to the traction device 400. This facilitates scheduling and control and can reduce labor costs.

[0154] In some embodiments, the battery production equipment 300 includes an AGV vehicle 32 for receiving a carrier vehicle 31 delivered by the traction device 400.

[0155] By using the above technical solution, AGV vehicle 32 is set up to receive the carrier vehicle 31 delivered by the traction device 400, so that the carrier vehicle 31 can be dispatched to the subsequent work station, which can reduce labor costs.

[0156] In some embodiments, the AGV vehicle 32 can be used to drive the carrier vehicle 31 to the traction device 400, or to receive the carrier vehicle 31 delivered by the traction device 400.

[0157] In some embodiments, the carrier 31 may also be pushed to the traction device 400 by other means, such as manually. In some embodiments, the carrier 31 may also be pushed away from the traction device 400 by other means, such as manually.

[0158] In some embodiments, when the traction device 400 drives the carrier 31 to pass through multiple workstations in sequence, if the traction device 400 drives the carrier 31 to move at a stable speed, the assembly equipment of the battery device 100 can move with the carrier 31 to achieve on-the-go assembly and improve efficiency.

[0159] In some embodiments, when the traction device 400 drives the carrier 31 to pass through multiple manual workstations in sequence, the workers can also move a distance along with the carrier 31 as the traction device 400 moves, enabling on-the-go assembly and improving efficiency. Furthermore, compared to the AGV requiring a period of start-stop time to enter and exit workstations, the traction device 400 can directly drive the carrier 31, thereby reducing worker waiting time and improving efficiency.
