[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] During the assembly of battery modules on a tray, contouring components need to be installed on the module tray to fit and hold the end plates of the battery modules. However, the contouring components on current module trays can only fit specific end plates, resulting in poor compatibility of the module trays. Utility Model Content

[0004] The purpose of this application is to provide a module tray, a tray conveying device, and battery production equipment to improve the poor compatibility of module trays in related technologies.

[0005] In a first aspect, embodiments of this application provide a module tray, comprising:

[0006] A tray is used to support a battery module, which includes multiple battery cells arranged along a first direction and end plates respectively disposed at both ends of the multiple battery cells.

[0007] The flexible pressure head is configured to undergo elastic deformation under external force. The flexible pressure heads are arranged in pairs, and the two pairs of flexible pressure heads are spaced apart on the support plate along a first direction.

[0008] A movable structure is used to drive the flexible pressure head to move along a first direction so that the two pairs of flexible pressure heads cooperate to clamp the two end plates, and the two pairs of flexible pressure heads elastically deform to adapt to the surface of the corresponding end plate away from the battery cell; the movable structure is mounted on the support plate.

[0009] In the technical solution of this application embodiment, a tray is set to support the battery module to facilitate the assembly and transportation of the battery module; flexible pressure heads are arranged in pairs on the tray, and the two pairs of flexible pressure heads are spaced apart on the tray along a first direction so that the battery module is placed between the two pairs of flexible pressure heads; a movable structure is provided to push the two pairs of flexible pressure heads closer to each other to clamp the battery module, and to make the flexible pressure heads elastically deform to adapt to the shape of the end plate of the battery module, thereby stably clamping the battery module; since the flexible pressure heads are used to elastically deform to adapt to the shape of the end plate, it can adapt to clamping end plates of various shapes, and has good compatibility.

[0010] In some embodiments, the module tray further includes a support for the flexible pressure head, the support being mounted on the tray, and the movable structure being connected to the corresponding support.

[0011] The above technical solution involves setting up supports to facilitate the flexible pressure head, making it easy to install the flexible pressure head on the support plate, and connecting the moving structure to the corresponding support so that the moving structure can drive the corresponding support to move the flexible pressure head on it along the first direction.

[0017] The above technical solution uses a retractable airbag, which can reduce the distance between two pairs of flexible pressure heads by expanding and contracting to clamp the battery module. A connector is provided on the retractable airbag to connect to a pressure controller. The pressure controller inflates the retractable airbag, causing it to expand and extend, while the pressure controller controls the discharge of gas from the retractable airbag, causing it to contract. The structure is simple and easy to control.

[0024] In some embodiments, the movable structure includes a slide supporting a flexible pressure head and a locking structure for locking the slide to a tray, the slide being slidably mounted on the tray along a first direction.

[0025] The above technical solution uses a sliding block and a locking structure, which is simple in structure. The sliding block is set to support the flexible pressure head so that the flexible pressure head can be slidably mounted on the support plate so that the flexible pressure head can be moved along the first direction. The locking structure is set so that after the sliding block is moved and the corresponding flexible pressure head is moved, the sliding block is locked, thereby locking the position of the flexible pressure head on the support plate so that the flexible pressure head abuts against the end plate of the battery module.

[0026] In some embodiments, the movable structure includes a guide assembly extending along a first direction, a slide being slidably mounted on the guide assembly, and the guide assembly being mounted on a tray.

[0027] By using the above technical solution and setting up a guide component, it is easy to install the slide on the tray and also easy to guide the slide to move smoothly and flexibly on the tray along the first direction.

[0028] In some embodiments, the locking mechanism includes bolts mounted on the slide.

[0052] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

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

[0054] 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.

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.

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.

[0060] A battery assembly typically consists of a housing and individual battery cells housed within the housing. Sometimes, multiple battery cells are assembled into a battery module before being installed in the housing.

[0061] A battery module generally includes a battery cell assembly formed by arranging multiple battery cells, and end plates located at both ends of the battery cell assembly. The end plates are used to clamp and fix the battery cell assembly so that the battery module forms an independent unit.

[0062] Battery module assembly is generally carried out on a tray. After placing the battery cells and end plates on the tray, the end plates at both ends of the battery module need to be clamped to fix or process the battery module, such as bonding and fixing the battery cells, using cable ties to fix the battery module, and applying adhesive to the sides of the battery cells.

[0063] To clamp and fix the battery module onto the tray, a conforming part that matches the shape of the end plate needs to be installed on the tray to support the end plate. However, different battery modules often use different end plate shapes, and the conforming part on the tray can only fit and clamp end plates of specific shapes. This results in poor compatibility of the module tray, making it difficult to process different types of battery modules.

[0064] Based on the above considerations, in order to improve the poor compatibility of module trays in related technologies, this application provides a module tray that supports battery modules by setting a tray plate, thereby supporting components of the battery module, such as supporting individual battery cells and end plates. A pair of flexible pressure heads are provided on the tray plate, and the two flexible pressure heads in the pair are spaced apart along a first direction on the tray plate, so that the battery module can be placed between the pair of flexible pressure heads, allowing the pair of flexible pressure heads to cooperate in clamping the battery module. A movable structure is provided to push the two flexible pressure heads closer together to clamp the battery module, and to allow the flexible pressure heads to elastically deform to adapt to the shape of the end plate of the battery module, thereby smoothly clamping the battery module. Using flexible pressure heads, when pressed by the end plate, they can elastically deform to adapt to the shape of the end plate, so that the flexible pressure heads can be used to clamp the end plate, and can adapt to clamping end plates of different shapes, improving the compatibility of the module tray.

[0065] The linear module mentioned in the embodiments of this application is also called a linear drive module or linear module; a linear module refers to a device, component, module, or mechanism that can move structural parts 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.

[0066] 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.

[0067] 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.

[0068] The ball screw type linear module mainly includes a ball screw, linear guide rail, ball screw bracket, motor, etc.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] The guiding component mentioned in the embodiments of this application, also known as a guide assembly, refers to a component used to guide the movement of an object. As an example, a guiding component may include a guide rail and a slider. The slider is slidably placed on the guide rail, connecting the slider to the object. The guide rail is mounted on a support medium to support the object on the support medium and guide the object to move along the guide rail. As an example, a guiding component may include two slide rails slidably connected to each other. One slide rail is connected to the object, and the other slide rail is connected to the support medium to movably support the object on the support medium and guide the object to move along the slide rail. As an example, a guiding component may include a guide rod and a sleeve fitted on the guide rod. The sleeve is connected to the object, and the guide rod is mounted on the support medium to support the object on the support medium and guide the object to move along the guide rod.

[0077] 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.

[0078] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0079] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. 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.

The end plates 22 are plates located at both ends of the battery module 200, serving functions such as fixing the battery cells 21, transferring heat, providing electrical connections, and providing isolation and protection. The end plates 22 can be made of metals such as steel and aluminum alloy, or high-strength plastics.

[0087] 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. The main body 11 includes a frame 111 and a base plate 112. The frame 111 is a portion of the structure forming the peripheral sidewalls of the housing 10, and the base plate 112 is the plate structure at the bottom of the housing body 11 that forms the receiving space. The cover 12 is the plate structure that covers the receiving space of the main body 11.

[0088] 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.

[0089] 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 may be aligned with the first direction M, and in this case, the side of the battery cell 21 with the largest area is parallel to the first direction M. As an example, the length direction of the battery cell 21 may be perpendicular to the first direction M, and in this case, the side of the battery cell 21 with the largest area is perpendicular to the first direction M.

[0091] 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.

[0102] The flexible pressure heads 42 are arranged in pairs, meaning two flexible pressure heads 42 form a pair. There can be one pair or multiple pairs of flexible pressure heads 42. Multiple pairs refer to two or more pairs. When one pair of flexible pressure heads 42 is used, it can clamp one battery module 200. When there are multiple pairs of flexible pressure heads 42, it can clamp multiple battery modules 200.

[0103] The pair of flexible pressure heads 42 are spaced apart along the first direction M on the support plate 41, which means that the two flexible pressure heads 42 in a pair are spaced apart along the first direction M so that the battery module 200 is placed between the two flexible pressure heads 42, thereby facilitating the pair of flexible pressure heads 42 to cooperate in clamping the end plates 22 at both ends of the battery module 200.

[0104] The moving structure 43 refers to a structure used to move the flexible pressure head 42 along the first direction M. As an example, the moving structure 43 can use a linear module to drive the flexible pressure head 42 to move along the first direction M, so that a pair of flexible pressure heads 42 move away from each other to assemble and place the battery module 200 between the pair of flexible pressure heads 42. Conversely, the linear module can drive the flexible pressure head 42 to move, so that the pair of flexible pressure heads 42 move closer together to clamp the battery module 200. As an example, the moving structure 43 can use a slider slidably mounted on a tray 41, which drives the flexible pressure head 42 to move along the first direction M. After the flexible pressure head 42 clamps the battery module 200, the slider is locked to the tray 41.

[0105] As an example, in a pair of flexible pressure heads 42, only one flexible pressure head 42 may be connected to the moving structure 43 to drive the two flexible pressure heads 42 to move closer to or further away from each other. As an example, in a pair of flexible pressure heads 42, each flexible pressure head 42 may be connected to the moving structure 43 separately to drive the two flexible pressure heads 42 to move closer to or further away from each other.

[0106] As an example, when multiple pairs of flexible pressure heads 42 are arranged side-by-side along the second direction N on the pallet 41, two or more flexible pressure heads 42 arranged side-by-side along the second direction N can be connected to the same moving structure 43 to drive the multiple flexible pressure heads 42 arranged side-by-side along the second direction N to move synchronously. As an example, when multiple pairs of flexible pressure heads 42 are arranged side-by-side along the second direction N on the pallet 41, each flexible pressure head 42 along the second direction N is connected to the moving structure 43 respectively, driving each pair of flexible pressure heads 42 to move. The second direction N is perpendicular to the first direction M.

[0107] With the battery module 200 placed between a pair of flexible pressure heads 42, the moving structure 43 is used to drive the flexible pressure heads 42 to move along the first direction M, so that the two pairs of flexible pressure heads 42 move closer to each other, so that the flexible pressure heads 42 abut against the end plate 22. Under the reaction force of the end plate 22, the flexible pressure heads 42 are elastically deformed, so that the shape of the flexible pressure heads 42 matches the shape of the end plate 22, and smoothly and well abuts against the end plate 22, thereby enabling the pair of flexible pressure heads 42 to well clamp the battery module 200.

[0108] In the technical solution of this application embodiment, a tray 41 is provided to support the battery module 200, so as to facilitate the assembly and transportation of the battery module 200; a pair of flexible pressure heads 42 are provided on the tray 41, and the two pairs of flexible pressure heads 42 are spaced apart along the first direction M on the tray 41, so that the battery module 200 is placed between the two pairs of flexible pressure heads 42; a movable structure 43 is provided, which can push the two pairs of flexible pressure heads 42 closer to each other to clamp the battery module 200, and make the flexible pressure heads 42 elastically deform to adapt to the shape of the end plate 22 of the battery module 200, thereby stably clamping the battery module 200; since the flexible pressure heads 42 are used to elastically deform to adapt to the shape of the end plate 22, it can adapt to clamping end plates 22 of various shapes, thus having good compatibility.

[0109] In some embodiments, please refer to Figure 2 and Figure 3 The module tray 400 also includes a support 44 for supporting the flexible pressure head 42. The support 44 is mounted on the tray 41, and the movable structure 43 is connected to the corresponding support 44.

[0110] Support 44 refers to the seat structure used to support the flexible pressure head 42. Support 44 can be made of metals such as steel and aluminum alloy, or high-strength plastics. Support 44 can be plate-shaped, block-shaped, or other similar shapes.

[0111] The support 44 is mounted on the support plate 41 so that the support plate 41 can support the support 44, thereby supporting the flexible pressure head 42.

[0112] The connection between the movable structure 43 and the corresponding support 44 means that the support 44 corresponding to the flexible pressure head 42 that is moved by the movable structure 43 is connected to the movable structure 43, so that the movable structure 43 can move the corresponding support 44, and thus move the flexible pressure head 42 on it.

[0113] Through the above technical solution, a support 44 is set to support the flexible pressure head 42, so that the flexible pressure head 42 can be installed on the support plate 41. The moving structure 43 is connected to the corresponding support 44 so that the moving structure 43 can drive the corresponding support 44 to drive the flexible pressure head 42 on it to move along the first direction M.

[0114] In some embodiments, the flexible pressure head 42 can also be directly supported on the support plate 41.

[0115] In some embodiments, please refer to Figure 2 and Figure 3 The flexible pressure head 42 includes an airbag 421, which is mounted on a corresponding support 44.

[0116] Airbag 421 refers to a rubber capsule structure with internal space. Because airbag 421 is flexible and contains a medium such as air or water, it can deform under compression to fit and support the end plate 22.

[0117] Through the above technical solution, the flexible pressure head 42 uses an airbag 421, which has a simple structure, low cost, and convenient control.

[0118] In some embodiments, the flexible pressure head 42 may also be a pressure head made of silicone, which adapts to the shape of the end plate 22 through the elastic deformation of the silicone.

[0119] In some embodiments, please refer to Figure 2 and Figure 3 The flexible pressure head 42 includes multiple airbags 421, which are arranged on the support 44.

[0120] "Multiple" refers to two or more items.

[0121] Through the above technical solution, the flexible pressure head 42 uses multiple airbags 421, which can be elastically deformed to adapt to the shape of the end plate 22. Thus, each airbag 421 can produce a small deformation and can better adapt to the shape of the end plate 22.

[0122] In some embodiments, please refer to Figure 2 and Figure 3 In the pair of flexible pressure heads 42: at least one flexible pressure head 42 corresponds to an airbag 421 that is a retractable airbag 4211. The moving structure 43 includes a connector 431 for connecting the air pressure controller 33. The connector 431 is connected to the retractable airbag 4211 and is supported on a corresponding support 44.

[0123] A retractable airbag 4211 refers to an airbag 421 whose length can change in one direction. For example, when compressed air or water is filled into the internal space of the retractable airbag 4211, its overall volume increases; conversely, when the gas or water is expelled from the internal space, its overall volume decreases. Through the structural design of the retractable airbag 4211, the direction of its expansion and deformation can be controlled, thereby achieving the retractable movement of the retractable airbag 4211. For example, the retractable airbag 4211 can be a structure formed by a bellows and an elastic sheet. For instance, the elastic sheet covers both ends of the bellows, and the expansion and contraction of the bellows is controlled by controlling the amount of the flowing medium, such as water or air, within the bellows. The elastic sheet abuts against the end plate 22 and undergoes elastic deformation to adapt to the shape of the end plate 22. The elastic sheet can be a silicone sheet, a rubber sheet, or a similar structure. As an example, the retractable airbag 4211 can also use a structure combining a guide component and an elastic bag, such as installing the guide component inside the elastic bag or installing the guide component on the outside of the elastic bag. The expansion direction of the elastic bag is controlled by the guiding action of the guide component when the elastic bag inflates, thereby achieving expansion and contraction. The elastic bag can be an airbag made of silicone or rubber.

[0124] Connector 431 refers to the structure used to connect the air pressure controller 33. Connector 431 being connected to the retractable airbag 4211 means that connector 431 is connected to the internal space of the retractable airbag 4211. As an example, connector 431 can be installed on the retractable airbag 4211 to directly connect to the internal space of the retractable airbag 4211. As an example, connector 431 can be connected to the internal space of the retractable airbag 4211 via a pipe fitting.

[0125] As an example, the air pressure controller 33 can be an inflator connected to the connector 431 to inflate the retractable airbag 4211, thereby controlling the retractable movement of the retractable airbag 4211. Alternatively, the air pressure controller 33 can be a control valve connected to the inflator and the connector 431. The control valve controls the connection between the connector 431 and the inflator, thereby controlling the inflation or deflation of gas into the retractable airbag 4211, and thus controlling the retractable movement of the retractable airbag 4211.

[0126] The connector 431 is supported on the support 44, so that the support 44 supports the connector 431. As an example, the connector 431 can be fixed to the support 44, so that the support 44 directly supports the connector 431. As an example, the connector 431 can be supported on the retractable airbag 4211, so that the retractable airbag 4211 supports the connector 431 on the support 44.

[0127] Through the above technical solution, the airbag 421 uses a retractable airbag 4211. The distance between the two paired flexible pressure heads 42 can be reduced by the expansion and contraction of the retractable airbag 4211, so as to clamp the battery module 200. A connector 431 is provided on the retractable airbag 4211 to connect to the air pressure controller 33. The air pressure controller 33 inflates the retractable airbag 4211, causing it to expand and extend. The air pressure controller 33 controls the discharge of gas from the retractable airbag 4211, causing it to contract. The structure is simple and easy to control.

[0128] In some embodiments, please refer to Figure 2 and Figure 3 Each pair of flexible pressure heads 42 includes a retractable airbag 4211, and each retractable airbag 4211 is connected to a connector 431, which is supported on a corresponding support 44.

[0129] The phrase "both flexible pressure heads 42 in a pair include retractable airbags 4211" means that when two flexible pressure heads 42 in a pair use airbags 421, both airbags 421 use retractable airbags 4211.

[0130] By using the above technical solution, the retractable airbags 4211 are arranged in pairs, which can better drive the distance between the two retractable airbags 4211 in order to clamp the battery module 200, and can be adapted to clamp a battery module 200 with a larger size along the first direction M.

[0131] In some embodiments, one of the pairs of flexible pressure heads 42 may use a retractable airbag 4211.

[0132] In some embodiments, of the pair of flexible indenters 42, one flexible indenter 42 may use an airbag 421, and the other may use an indenter made of silicone.

[0133] In some embodiments, please refer to Figures 4 to 6 The flexible pressure head 42 includes multiple elastic telescopic rods 422 and a seat 423 supporting the multiple elastic telescopic rods 422. The seat 423 is mounted on the support plate 41.

[0134] A flexible telescopic rod 422 is a rod that can contract under the application of external force and return to its original length after the external force is removed. As an example, the flexible telescopic rod 422 can use a structure combining a spring and a rod, with the spring driving the rod to elastically return to its original position. As another example, the flexible telescopic rod 422 may include a sleeve, a telescopic rod inserted into the sleeve, and an elastic element placed within the sleeve. The elastic element elastically pushes the telescopic rod outwards, allowing it to elastically return to its original position. The elastic element can be a spring, a spring plate, or other similar structure.

[0135] The base 423 refers to the seat structure used to support the elastic telescopic rod 422. The base 423 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics. The base 423 can be plate-shaped, block-shaped, or other similar shapes.

[0136] The seat 423 is mounted on the support plate 41 so that the support plate 41 supports the seat 423, thereby supporting each elastic telescopic rod 422.

[0137] Multiple elastic telescopic rods 422 are provided on the seat body 423. The elastic telescopic rods 422 abut against the end plate 22. Under the reaction force of the end plate 22, the elastic telescopic rods 422 are compressed. Since the compression length of the elastic telescopic rods 422 at different positions is different, it adapts to the shape of the end plate 22, thereby adapting to abut against end plates 22 of different shapes.

[0138] Through the above technical solution, the flexible pressure head 42 uses multiple elastic telescopic rods 422. The extension length of each elastic telescopic rod 422 is used to adapt to the shape of the end plate 22. The structure is simple and easy to hold the end plate 22 of the battery module 200.

[0139] In some embodiments, please refer to Figures 4 to 6 Multiple elastic telescopic rods 422 are arrayed on the base 423.

[0140] An array is an arrangement in a certain order.

[0141] By using the above technical solution, multiple elastic telescopic rods 422 are arrayed on the base 423, which facilitates the layout of the elastic telescopic rods 422 so that they can be installed on the base 423.

[0142] In some embodiments, the paired flexible pressure heads 42 can be constructed by combining both flexible pressure heads 42 with a base 423 using an elastic telescopic rod 422.

[0143] In some embodiments, in a pair of flexible pressure heads 42, both flexible pressure heads 42 may use airbags 421.

[0144] In some embodiments, in the pair of flexible pressure heads 42, one flexible pressure head 42 may use an airbag 421, and the other flexible pressure head 42 may use a structure combining an elastic telescopic rod 422 and a seat 423.

[0145] In some embodiments, when the pallet 41 is provided with a support 44 and the flexible pressure head 42 includes a seat 423, the seat 423 can be mounted on the support 44, and the support 44 can support the seat 423, thereby mounting the seat 423 on the pallet 41.

[0146] In some embodiments, please refer to Figures 4 to 6The movable structure 43 includes a slide 432 that supports the flexible pressure head 42 and a locking structure 433 that locks the slide 432 onto the support plate 41. The slide 432 is slidably mounted on the support plate 41 along the first direction M.

[0147] The slide 432 refers to the seat 423 that slides on the support plate 41. The slide 432 can be plate-shaped, block-shaped, or any other shape, as long as it can support the flexible pressure head 42 and slide on the support plate 41. The slide 432 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics.

[0148] The locking structure 433 refers to a structure that can lock the slide 432. As an example, the locking structure 433 can use a wedge; after the slide 432 moves to a set position, the wedge locks the slide 432. As an example, the locking structure 433 can include a pin; multiple insertion holes can be arranged on the support plate 41 along a first direction M. After the slide 432 moves to the set position, the pin is inserted into the corresponding insertion hole to stop the slide 432, thereby locking the slide 432. As an example, the locking structure 433 can also use a linear module; the linear module pushes the slide 432 to move, and after the slide 432 moves to the set position, the linear module locks the position of the slide 432.

[0149] The slide block 432 is slidably mounted on the support plate 41 along the first direction M, so that the flexible pressure head 42 can be driven to move on the support plate 41 along the first direction M through the slide block 432.

[0150] As an example, in a pair of flexible pressure heads 42, one flexible pressure head 42 can be mounted on a slide 432, while the other flexible pressure head 42 can be fixed on a support plate 41. The slide 432 can be used to drive the flexible pressure head 42 on it to move along the first direction M.

[0151] As an example, in a pair of flexible pressure heads 42, the two flexible pressure heads 42 can be respectively mounted on two slide blocks 432, so that the two flexible pressure heads 42 can be moved to slide on the support plate 41 respectively.

[0152] Through the above technical solution, the moving structure 43 uses a slide block 432 and a locking structure 433, which is simple in structure. The slide block 432 is set to support the flexible pressure head 42 so that the flexible pressure head 42 can be slidably mounted on the support plate 41 so as to drive the flexible pressure head 42 to move along the first direction M. The locking structure 433 is set to lock the slide block 432 after the moving slide block 432 moves and drives the corresponding flexible pressure head 42 to move, thereby locking the position of the flexible pressure head 42 on the support plate 41 so that the flexible pressure head 42 abuts against the end plate 22 of the battery module 200.

[0153] In some embodiments, please refer to Figures 4 to 6The movable structure 43 includes a guide assembly 434 extending along a first direction M, a slide block 432 slidably mounted on the guide assembly 434, and the guide assembly 434 mounted on the support plate 41.

[0154] The guide component 434 is a component used to support and guide the movement of the slide 432. The specific structure of the guide component 434 is as described in the above embodiment and will not be repeated here.

[0155] By using the above technical solution, the guide component 434 can be set to facilitate the installation of the slide 432 on the tray 41, and also facilitate the smooth and flexible movement of the slide 432 on the tray 41 along the first direction M.

[0156] In some embodiments, a groove can be provided on the tray 41, the groove extending along the first direction M, and a sliding part that fits into the groove is provided on the slide block 432, thereby guiding the slide block 432 to move along the first direction M on the tray 41 through the cooperation of the sliding part and the groove.

[0157] In some embodiments, please refer to Figures 4 to 6 The locking structure 433 includes bolts mounted on the slide 432.

[0158] A bolt is a rod with threads on its outer circumference.

[0159] The locking structure 433 uses a bolt. After the slide 432 moves to the set position, the bolt is rotated so that it abuts against the support plate 41 to lock the slide 432 onto the support plate 41; and the bolt is rotated in the opposite direction to separate the bolt from the support plate 41 to unlock the slide 432.

[0160] As an example, a bolt can be installed on the slide 432 to lock and unlock it. Alternatively, multiple bolts can be installed on the slide 432 to lock it securely.

[0161] The above technical solution uses bolts for locking structure 433, which is simple in structure, easy to install, and low in cost.

[0162] In some embodiments, please refer to Figures 4 to 6 The movable structure 43 includes a slide 432 supporting the flexible pressure head 42, a locking structure 433 locking the slide 432 onto the support plate 41, and a linear module 435 driving the slide 432 to move along a first direction M. The slide 432 is connected to the linear module 435, which is mounted on the support plate 41. The flexible pressure head 42 is slidably supported on the support plate 41 by the slide 432, the linear module 435 drives the slide 432 to move along the first direction M, and after the slide 432 moves to a set position, the locking structure 433 locks the position of the slide 432.

[0163] In some embodiments, the pallet 41 is provided with a base 411, which is used to support the battery module 200, and the flexible pressure head 42 is supported on the base 411.

[0164] The base 411 refers to the support structure used to accommodate and support the battery module 200. The base 411 can be plate-shaped or block-shaped. The base 411 can be made of metals such as steel and aluminum alloy, or it can be made of materials such as high-strength plastics.

[0165] Through the above technical solution, a base 411 is set on the tray 41 to properly position and support the battery module 200, and to reduce wear on the tray 41, thereby protecting the tray 41.

[0166] In some embodiments, a heating structure may be provided in the base 411 to heat the battery module 200. The heating structure may be a heating wire or a heating tube, etc.

[0167] In some embodiments, when the movable structure 43 includes a base 411, a slide 432 and a locking structure 433, the slide 432 is slidably supported on the base 411, and the locking structure 433 can lock the slide 432 onto the base 411.

[0168] Please see Figure 2 and Figure 3 According to some embodiments of this application, a module tray 400 is provided, including a tray 41, flexible pressure heads 42, a moving structure 43, and a support 44 for supporting the flexible pressure heads 42; the tray 41 is used to support a battery module 200. The battery module 200 includes a plurality of battery cells 21 arranged along a first direction M and end plates 22 respectively disposed at both ends of the plurality of battery cells 21. The support 44 is mounted on the tray 41. The flexible pressure heads 42 are arranged in pairs, with two pairs of flexible pressure heads 42 spaced apart along the first direction M on the tray 41. Each flexible pressure head 42 includes a retractable airbag 4211, which is supported on the support 44. The moving structure 43 includes a connector 431 for connecting a pressure controller 33, the connector 431 communicating with the retractable airbag 4211, and the connector 431 being supported on the corresponding support 44.

[0169] A connector 431 is provided on the retractable airbag 4211 to connect to the air pressure controller 33. The air pressure controller 33 controls the discharge of gas from the retractable airbag 4211, causing the retractable airbag 4211 to contract, so that the battery module 200 can be placed or assembled between pairs of retractable airbags 4211 spaced M apart along the first direction. The air pressure controller 33 inflates the retractable airbag 4211, causing the retractable airbag 4211 to expand and extend, so that the retractable airbag 4211 abuts against the end plates 22 at both ends of the battery module 200. The retractable airbag 4211 is deformed by the pressure of the end plates 22 to adapt to the shape of the end plates 22, thereby being compatible with end plates 22 of various shapes and improving the compatibility of the module tray 400.

[0170] Please see Figures 4 to 6 According to some embodiments of this application, a module tray 400 is provided, including a tray 41, flexible pressure heads 42, and a moving structure 43. The tray 41 is used to support a battery module 200. The battery module 200 includes a plurality of battery cells 21 arranged along a first direction M and end plates 22 respectively disposed at both ends of the plurality of battery cells 21. The flexible pressure heads 42 are arranged in pairs, with two pairs of flexible pressure heads 42 spaced apart along the first direction M on the tray 41. Each flexible pressure head 42 includes a plurality of elastic telescopic rods 422 and a seat 423 supporting the plurality of elastic telescopic rods 422. The moving structure 43 includes a slide 432 supporting the flexible pressure head 42, a locking structure 433 locking the slide 432 to the tray 41, and a linear module 435, wherein the slide 432 is connected to the linear module 435.

[0171] The flexible pressure head 42 is slidably supported on the tray 41 by the slide block 432. The linear module 435 drives the slide block 432 to move along the first direction M, so that the pairs of flexible pressure heads 42 move away from each other, so that the battery module 200 can be assembled and placed between the pairs of flexible pressure heads 42. The linear module 435 drives the slide block 432 to move the flexible pressure head 42 along the first direction M, so that the pairs of flexible pressure heads 42 move closer to each other, so that the elastic telescopic rod 422 of the flexible pressure head 42 abuts against the end plate 22. Under the reaction force of the end plate 22, the elastic telescopic rod 422 is compressed. Since the compression length of the elastic telescopic rod 422 is different at different positions, it adapts to the shape of the end plate 22, thereby adapting to abut against end plates 22 of different shapes, thus being compatible with abutting against end plates 22 of various shapes, improving the compatibility of the module tray 400. After the flexible pressure head 42 clamps the battery module 200, the position of the slide block 432 is locked by the locking structure 433.

[0172] Please see Figures 2 to 6 This application provides a pallet conveying device 300, including a conveying vehicle 31 and a modular pallet 400 as described in the above embodiment, wherein the modular pallet 400 is supported on the conveying vehicle 31.

[0173] The conveyor 31 refers to a trolley structure capable of transporting the module pallet 400. As an example, the conveyor 31 can be an AGV (Automated Guided Vehicle). An AGV is an automated device capable of autonomously driving along a predetermined path or environment without human intervention, following a preset program or real-time instructions to complete tasks such as material handling and transportation. As an example, the conveyor 31 can have a frame structure with wheels.

[0174] A conveyor 31 is provided to transport the module tray 400 to various processes in the battery device manufacturing process for the assembly and use of the battery module 200.
