Description

Technical Field

[0001] This utility model belongs to the technical field of battery module production equipment, specifically relating to a turnover cart for battery module production. Background Technology

[0002] In the production process of power battery modules, during the installation of battery cells, current collectors, and nickel sheets, workers need to transfer the battery modules from the transfer cart into the equipment for welding. After welding, they are transferred back from the equipment to the transfer cart for the next step. After the battery modules with carriers are pulled out of the equipment and transferred into the transfer cart, the battery modules and carriers need to be secured to the transfer cart for operation to prevent them from slipping due to operator error, causing losses and endangering personnel safety. On-site operators generally use thin bolts inserted between the carrier and the transfer cart rollers to limit the movement of the modules and carriers. During operation, the vibration and impact caused by the frequent sliding of the workpieces and modules can easily cause the bolts to bend or break, increasing maintenance costs and posing a risk of material slippage. The module carriers need to be pushed and pulled repeatedly before and after the welding process, and operators need to frequently disassemble deformed bolts, which not only affects work efficiency but also easily leads to material falling accidents due to fixation failure. This method is inconvenient and poses safety hazards. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a turnover cart for battery module production, which facilitates module transfer while achieving reliable positioning to avoid the risk of module falling. It has a simple structure, is easy to operate, and solves the problems of rapid locking and safety protection under dynamic working conditions.

[0004] To achieve the above and other related objectives, this utility model provides a turnover cart for battery module production, comprising:

[0005] The frame body includes a column and a support portion fixed to one end of the column;

[0006] Guide side plates, which are arranged in parallel on opposite sides of the support portion;

[0007] A limiting component is disposed on the main body of the vehicle frame, including a first limiting group and a second limiting group;

[0008] The first limiting group and / or the second limiting group can rotate relative to the column to switch between the first working position and the second working position;

[0009] When in the first working position, the first limiting group and the second limiting group are located on the first side of the support, which is the side on which the guide side plate is provided.

[0010] When in the second working position, the first limiting group and the second limiting group are located on the second side of the support, and the second side is the side adjacent to the first side;

[0011] When at least one of the first limiting group and the second limiting group is in the first working position, the guide side plate forms a material transfer channel;

[0012] When both the first limit group and the second limit group are located in the second working position, the first limit group, the second limit group and the guide side plate form a material stop structure.

[0013] In an optional embodiment of this utility model, the column includes a column body and an inner shaft tube welded to the column body. The inner shaft tube is disposed at one end near the support portion. The limiting component is rotatably connected to the column through the inner shaft tube, and the column body forms an axial limit at the end of the inner shaft tube.

[0014] In an optional embodiment of this utility model, the limiting component includes:

[0015] A rotating base, wherein the rotating base is rotatably connected to the column via the inner shaft tube;

[0016] A limiting part is radially connected to one side of the rotating base, and the limiting part switches between the first working position and the second working position when the rotating base rotates.

[0017] In an optional embodiment of the present invention, a limiting groove is further formed on the side of the support portion, and the limiting portion cooperates with the limiting groove.

[0018] In an optional embodiment of the present invention, a fixing component is further included, which is disposed on the side of the support portion to fix the limiting component.

[0019] In an optional embodiment of this utility model, the fixing component includes a first fixing component disposed on the first side and a second fixing component disposed on the second side.

[0039] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] In the current battery module production process, turnover carts are used for the transfer and fixation of the carrier and the module. However, turnover carts generally rely on thin bolts inserted between the carrier and the rollers for positioning. This method is prone to bolt bending or breaking due to shaking during operation, which poses safety hazards such as bolts being difficult to pull out and workpieces slipping. In addition, since the module carrier needs to be pushed and pulled repeatedly before and after the welding process, operators need to frequently disassemble deformed bolts, making the operation complicated and the work efficiency low.

[0042] Please see Figures 1 to 5This utility model proposes a turnover cart for battery module production, including a frame body 100, guide side plates 200, limiting components 300, and fixing components 400. The frame body 100 forms a load-bearing structure through a column 110 and a support portion 120 fixed to one end of the column 110; a pair of guide side plates 200 are arranged parallel to each other on opposite sides of the support portion 120; the limiting components 300 are disposed on the frame body 100, at least one of which can rotate relative to the column 110 to realize switching between a first working position and a second working position. In the first working position, it can form a material transfer channel, which facilitates the carrier and module to slide in along the guide side plates 200. In the second working position, it can form an end stop structure to prevent the workpiece from slipping. The fixing components 400 and the limiting components 300 are adjusted and cooperated to quickly fix it in the first working position or the second working position. This design avoids the risk of human error through structural optimization, and the structural strength is reliable, reducing the risk of fixation failure. The working position can be quickly switched by operating only at one end of the frame body 100, simplifying the transfer process and enabling safer and more efficient transfer and positioning.

[0043] Please see Figures 1 to 5 In an optional embodiment of this utility model, the frame body 100 is composed of four uprights 110 and a support part 120 welded to the top to form the frame body. The support part 120 is a support plate on which the battery module and the carrier are placed. The bottom of the frame body 100 is also provided with a wheel set, such as four universal wheels respectively set at the four feet of the bottom of the frame body 100, which can realize flexible movement. The frame body 100 is also provided with an anti-tipping bracket to prevent tilting under load.

[0044] Please see Figures 1 to 5 In an optional embodiment of this utility model, the column 110 includes a column body 111 and an inner shaft tube 112 welded to its end. The inner shaft tube 112 is disposed near the support part 120. An adjustable limiting component 300 is rotatably connected to the column 110 through the inner shaft tube 112, thereby limiting the battery module and the carrier at the end of the frame body 100. The column body 111 forms an axial limit at the end of the inner shaft tube 112, ensuring the rotational stability of the limiting component 300 and preventing it from falling off. At the same time, it achieves axial fixation of the limiting component 300. Therefore, after the limiting component 300 is adjusted, the fixing component 400 only needs to limit its circumferential movement to prevent it from rotating, which is convenient to operate and highly safe. The inner shaft tube 112 and the column body 111 adopt an integrated welding design to avoid structural loosening and to balance rotational flexibility and overall rigidity. In other embodiments, the inner shaft tube 112 can also be connected and locked to the column body 111 by a flange or snap ring, so as to realize the function of the rotating shaft while facilitating disassembly and maintenance.

[0045] Please see Figures 1 to 5In an optional embodiment of the present invention, the support part 120 includes a first side 121 and a second side 122. The first side 121 is the side on which the guide side plate 200 is provided, and the second side 122 is the side adjacent to the first side 121. The limiting component 300 can rotate around the column 110 between the adjacent first side 121 and the second side 122 to realize the switching between the first working position and the second working position.

[0046] Please see Figures 1 to 5 In an optional embodiment of this utility model, a pair of guide side plates 200 are arranged in parallel on opposite sides of the support portion 120 and extend along a first direction, which can be the length direction or the width direction of the frame body 100. The guide side plates 200 can be welded to the left and right sides of the top surface of the support portion 120, arranged parallel to the first side surface 121, for guiding the module positioning and limiting the module on both sides to prevent it from shaking and falling. The inner side of the guide side plate 200 can be provided with an inclined guide slope, on which a buffer pad can be provided to prevent the module from bumping.

[0047] Please see Figures 1 to 5 In an optional embodiment of this utility model, a sliding channel 210 is provided inside the guide side plate 200. Two sets of sliding channels 210 are respectively provided on opposite sides of the two guide side plates 200, each including a guide rail and a built-in roller assembly. The two guide rails are respectively provided on opposite sides of the two guide side plates 200, and double-sided constraints prevent lateral displacement. The guide rails facilitate the transfer of the carrier and module between the equipment and the turnover vehicle. The roller assembly is provided inside the guide rail, with the roller height slightly higher than the guide rail depth, so that the bottom of the carrier makes point contact with the roller, reducing sliding friction resistance and pushing force, making the transfer of the carrier more labor-saving and efficient. At the same time, the roller assembly distributes the bearing pressure and avoids deformation of the guide rail.

[0048] Please see Figures 1 to 5 In an optional embodiment of this utility model, a limiting component 300 is disposed on the frame body 100, comprising a first limiting group 310 and a second limiting group 320. The first limiting group 310 and / or the second limiting group 320 are rotatable relative to the column 110 to switch between a first working position and a second working position. When in the first working position, the first limiting group 310 and the second limiting group 320 are located on the first side 121 of the support portion 120. When in the second working position, the first limiting group 310 and the second limiting group 320 are located on the second side 122 of the support portion 120. When at least one of the first limiting group 310 and the second limiting group 320 is in the first working position, the guide side plate 200 forms a material transfer channel. When both the first limiting group 310 and the second limiting group 320 are in the second working position, the first limiting group 310, the second limiting group 320, and the guide side plate 200 form a material stop structure.

[0049] Please see Figures 1 to 5 In one specific embodiment of this utility model, both the first limiting group 310 and the second limiting group 320 are adjustable limiting components. During material transfer, the limiting components 300 on either side or both sides can be adjusted, and each group of limiting components 300 operates independently, adapting to different working conditions. Either side can be docked with the equipment for workpiece transfer, adapting to multi-directional equipment layouts, reducing the frequency of turning and adjusting the turnover vehicle, making operation more convenient, and improving material transfer efficiency. Generally, during material transfer, only one end of the guide side plate 200 needs to be adjusted to form a transfer channel, while the limiting component 300 on the other side remains unchanged in the second working position. In other embodiments, one of the first limiting group 310 and the second limiting group 320 can be set as a fixed limiting component 300, for example, by welding a baffle on one side for limiting, and setting an adjustable structure on the other side, reducing manufacturing costs while meeting the basic unidirectional transfer requirements.

[0050] Please see Figures 1 to 5 In an optional embodiment of this utility model, the first limiting group 310 includes two limiting members. When the two limiting members rotate simultaneously to the first side 121, the guide side plate 200 can form a material transfer channel. When the two limiting members rotate simultaneously to the second side 122, a stop can be formed at one end of the guide side plate 200. At the other end of the guide side plate 200, the second limiting group 320 is held on the second side 122 and forms a stop at that end. The first limiting group 310, the second limiting group 320 and the guide side plate 200 can form a material stop structure around the perimeter, achieving effective limiting and simplifying the overall structure. It is understandable that the structure of the first limit group 310 and the second limit group 320 is not limited. For example, both the first limit group 310 and the second limit group 320 can be adjustable limit components. In actual operation, one of them can be selected for adjustment according to the equipment orientation, or one of them can be an adjustable limit component and the other can be a fixed limit component. When transferring materials, the adjustable end is connected to the equipment and adjusted through that side. The structure of the limit component 300 is also not limited. It can be two oppositely arranged limit blocks or an integral limit baffle, as long as it can achieve the limiting function on that side.

[0051] Please see Figures 1 to 5In an optional embodiment of this utility model, the limiting component 300 includes a rotating base 311 and a limiting part 312. The rotating base 311 is rotatably connected to the column 110 via an inner shaft tube 112, and can rotate 270° around the column 110, rotating between the first side surface 121 and the second side surface 122. The limiting part 312 is fixed radially to one side of the base. When the rotating base 311 rotates, the limiting part 312 switches to the first or second working position, forming a channel opening or a baffle at the end of the guide side plate 200, respectively. Specifically, the rotating base 311 is rotatably connected to the inner shaft tube 112 via a bearing, such as a deep groove ball bearing. Its inner ring is tightly fitted to the outer wall of the inner shaft tube 112, and its outer ring is fixed to the rotating base 311, converting sliding friction into rolling friction, greatly reducing rotational resistance, ensuring that the baffle can be easily rotated with one hand. At the same time, the axial bearing capacity of the bearing can resist the lateral force generated when the carrier moves, preventing the rotating mechanism from jamming.

[0052] Please see Figures 1 to 5 In one optional embodiment of this utility model, the rotating base 311 and the limiting part 312 can be an integral structure to ensure structural strength. Its shape can be, for example, an L-shaped structure. The rotating base 311 consists of two parallel base sections and an inclined block connecting them. The two parallel base sections are rotatably connected to the column 110 of the frame body 100 via two spaced-apart inner shaft tubes 112, forming a dual-axis synchronous rotation structure to enhance the torsional stiffness of the component. The inclined block is welded between the two base sections to form a triangular support, converting the bending moment generated when the vehicle is pushed into compressive stress on the inclined block, preventing local deformation of the base, and simultaneously adapting to the structure of the frame body 100 to simplify the overall structure. It should be noted that the shape of the limiting part 312 is not limited and can also be a square plate, a fence structure, etc., to adapt to diverse workpiece sizes. In other embodiments, the limiting part 312 and the rotating base 311 can also be a separate connection design, employing a telescopic design. The length can be adjusted by springs or slide rails to adapt to the limiting requirements of different specifications of vehicles, enhancing versatility.

[0053] Please see Figures 1 to 5 In an optional embodiment of this utility model, a buffer pad can also be provided at the end region of the limiting part 312. For example, the edge of the limiting part 312 can be covered with rubber or silicone material. When the battery module comes into contact with the limiting part 312 due to transportation vibration, the buffer pad absorbs the impact energy through deformation, avoiding rigid collisions that could cause damage to the module surface or loosening of the internal structure. The buffer pad can be designed as a detachable structure, fixed to the surface of the limiting part 312 by Velcro or slots, making it easy to replace or adjust the hardness of the buffer pad after wear, further improving adaptability and maintenance convenience.

[0054] Please see Figures 1 to 5In an optional embodiment of this utility model, a limiting groove 130 is also formed on the side of the support part 120, which is connected to the limiting part 312. Specifically, for example, the limiting part 312 is a square block, the limiting groove 130 has a rectangular cross-section, the depth of the limiting groove 130 is the same as the thickness of the block, and the width of the limiting groove 130 and the limiting part 312 are fitted together to ensure smooth engagement during rotation. The end of the limiting groove 130 may also be chamfered to avoid collision when the limiting part 312 rotates. When the block rotates to the first working position or the second working position, it is engaged in the limiting groove 130. The end face of the block is basically flush with the opening end face of the groove, i.e., the first end face 121 or the second end face 122 of the support part 120. The limiting is achieved by quickly closing the fixing component 400 on it against the end face of the block. The operation is convenient and can achieve rapid switching.

[0055] Please see Figures 1 to 5 In an optional embodiment of this utility model, the fixing component 400 is disposed on the side of the support portion 120 to fix the limiting component 300 to the first working position or the second working position. Specifically, the fixing component 400 includes a first fixing component 410 and a second fixing component 420. The first fixing component 410 and the second fixing component 420 are respectively disposed on the first side 121 and the second side 122. When the limiting component 300 rotates to the first working position, it is fixed by the first fixing component 410 to ensure that the adjustable limiting component will not rotate and damage the transfer channel when the module is transferred. When the limiting component 300 rotates to the second working position, it is fixed by the second fixing component 420 to ensure the stability and reliability of the stop structure during module transfer and transportation.

[0056] Please see Figures 1 to 5 In one optional embodiment of this utility model, the fixing component 400 is a pin assembly, which includes a base disposed on both sides of the limiting groove 130, a pin slidably connected to the base, and a pin locking structure. When the pin is inserted into the side holes of the two bases, it abuts against the end face of the limiting part 312 to limit it and prevent it from rotating. The pin is made of high carbon steel or alloy material, and the diameter-to-length ratio is designed with mechanical optimization to effectively resist the lateral force caused by module shaking, avoid bending or breakage, and disperse the external force to the frame body 100 through the rigid cooperation between the base and the pin, reducing local stress concentration and preventing fixing failure. To ensure that the pin will not loosen under vibration after fixing and to ensure the stability of the limiting, a pin locking structure, such as a limiting pin hole, is also provided on the pin and the base to prevent the pin from loosening. In other embodiments, elastic pins or the like can also be used to achieve quick locking and improve operating efficiency.

[0057] Please see Figures 1 to 5In an optional embodiment of this utility model, the fixing component 400 can also be a combination structure of a rotating locking member and a buckle. The rotating locking member and the first buckle are disposed on one side of the limiting groove 130, and the second buckle is disposed on the other side of the limiting groove 130. When the rotating locking member is engaged with the first buckle, the limiting component 300 can rotate into the groove. Then the rotating locking member is rotated and engaged with the second buckle. The rotating locking member presses against the end face of the limiting component 300, thereby fixing it in the limiting groove 130. The structure is simple, the operation is convenient, and there will be no accidental unlocking.

[0058] Understandably, the structure of the fixing component 400 is not limited. The first fixing component 410 only needs to be able to lock the limiting component 300 in a simple way. It can adopt a pin structure, a snap-fit ​​structure or a magnetic lock, etc., to quickly position the limiting component 300. The second fixing component 420 needs to ensure the stability of the limiting component 300 under external force during transportation while quickly positioning. It can adopt a self-locking pin or snap-fit ​​structure, and ensure its structural strength through structural design.

[0059] Please see Figures 1 to 5 During operation, the first limiting group 310 remains in the second working position, and the second limiting group 320 is rotated to the first working position (in the same direction as the guide side plate 200) and fixed to form an open channel. The vehicle and module slide into the turnover vehicle along the guide rail via the roller group. Then, the second limiting group 320 is rotated to the second working position (perpendicular to the guide side plate 200) and engages with the limiting groove 130 and is locked by a pin. At this time, the limiting component 300 and the guide side plate 200 form a four-sided enclosure structure around the module. During transportation, the guide side plate 200 and the limiting component 300 work together to limit the movement and prevent the risk of the vehicle slipping.

[0060] In summary, the battery module production turnover cart of this utility model uses a rotatable limiting component and a pin assembly to form a mechanical barrier at the end face, which has higher resistance to lateral impact, reduces the risk of fixing failure, and effectively avoids the risk of module slippage. The guide side plate 200 is equipped with a roller assembly and a sliding channel 210 on its inner side to reduce pushing resistance. Combined with the independent adjustment of the adjustable limiting component 300 on both sides, it is suitable for multi-directional equipment docking, reduces the frequency of turnover cart turning, and enables efficient transfer. The limiting groove 130 and the fixing component 400 are aligned to limit... The positioning component 300 is fixed in place, and different functions can be quickly switched by rotating the positioning component 300 and opening and closing the fixing component 400 without disassembling parts, which significantly improves the efficiency of production line operation. The integrated welding design of the inner shaft tube 112 and the column 110 ensures the stable bearing of the rotating base 311. The bearing connection reduces frictional resistance. The combination of the L-shaped positioning part 312 and the buffer pad takes into account both bending strength and anti-collision protection to avoid module damage. The overall structure is compact and reliable, taking into account strength, flexibility and convenience, and is suitable for the safe transportation of battery modules.
