Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery processing equipment, in particular to an automatically changeable tray. Background Art

[0002] With the rapid development of the new energy vehicle industry, lithium-ion battery technology, as the core power system of electric vehicles, has become a key means of improving production efficiency and product quality through automation and intelligent manufacturing processes. In the production of lithium-ion battery modules, trays serve as crucial auxiliary tooling, supporting battery cells and completing a series of module assembly and testing processes. Therefore, the rationality of tray design and use directly impacts the production efficiency and automation level of the entire lithium-ion battery module production line.

[0003] Currently, the common practice in lithium battery module production lines is to utilize fixed-size pallets for module production. The pallet's size and structure are typically designed based on the specifications of a specific module. However, in actual production, the size and type of lithium battery modules can vary significantly depending on the needs of different customers or applications. For example, some modules may be larger, while others may be smaller. Furthermore, to maximize production line utilization, many factories have adopted a co-production model, whereby different types and specifications of modules are produced simultaneously or alternately on the same production line.

[0004] However, due to the differences in size and structure between modules, traditional fixed pallet designs face numerous challenges in actual production. This is especially true in co-production lines, where the production of modules of varying specifications often requires adjustment or replacement of pallets to accommodate the loading and positioning requirements of the various modules. This pallet adjustment or replacement process often requires manual intervention, is cumbersome, and increases the operator's workload. Furthermore, frequent pallet replacement or adjustment not only prolongs the changeover time of the production line, but also reduces production efficiency and impacts the overall output of the production line. For larger manufacturers, this inefficient changeover method struggles to meet the requirements of efficient, automated production.

[0005] Therefore, how to achieve the production of pallets that adapt to different specifications of lithium battery modules to improve the pallet change efficiency, reduce manual operations, and improve the production efficiency and automation level of the production line has become a technical problem that needs to be solved urgently. Utility Model Content

[0006] The main purpose of this utility model is to provide an automatically changeable pallet, which aims to realize the production of lithium battery modules with different specifications adaptively, thereby improving the pallet's change efficiency, reducing manual operations, and improving the production efficiency and automation level of the production line.

[0007] In order to achieve the above-mentioned purpose, the present invention provides an automatically changeable pallet, comprising:

[0008] A supporting base plate is provided with a through hole;

[0009] A guide rail connected to the supporting base plate;

[0010] At least two clamping plates, when there are two clamping plates, the two clamping plates are connected to the guide rail and can move closer to or farther from each other along the length direction of the guide rail to form clamping areas of different sizes between the two clamping plates; and

[0011] The lifting component has a positioning piece and is arranged in the through hole. When the clamping area clamps the battery cell to form a first module, the lifting component extends out of the through hole to allow the middle partition in the first module to be plugged into the positioning piece.

[0012] The adjustable clamping plate design allows for a customized clamping zone by adjusting the position of the clamping plate, eliminating the need to change the pallet. This significantly increases the pallet's flexibility, enabling it to quickly adapt to the production needs of modules of varying specifications. This reduces the time and manual labor associated with frequent pallet changes, improving production line efficiency. Furthermore, it not only increases the level of automation in the production process, but also enhances assembly precision and efficiency, avoiding the potential positioning errors associated with manual installation.

[0013] In one embodiment of the present application, the guide rails are arranged above the supporting base plate, and gasket strips for supporting the battery cells are provided between the guide rails, and the horizontal height of the gasket strips is the same as the horizontal height of the guide rails.

[0014] The spacer bar provides a stable and steady support surface for the battery cell, preventing it from directly contacting the hard base plate, thus reducing the risk of damage during production and transportation. The spacer bar is consistent in height with the guide rail, ensuring the balance of the battery cell when clamping.

[0015] In one embodiment of the present application, a positioning post is provided on a side of the clamping plate close to the battery cell, and the positioning post can be inserted into a positioning hole of the end plate of the battery cell module.

[0016] The plug-in design of the positioning posts and positioning holes greatly improves the installation accuracy of the module end plates. Through this physical structure, the module end plates can be accurately placed in place during the loading process, preventing the module end plates from shifting or tilting due to vibration or movement.

[0017] In one embodiment of the present application, rail clamps are provided at both ends of the guide rail.

[0018] The guide rail clamps are arranged at both ends of the guide slide rail, which can effectively limit the splint from moving out of the guide slide rail, thereby improving the safety of the splint during operation.

[0019] In one embodiment of the present application, the lifting assembly includes:

[0020] A mounting bracket connected to the bottom of the supporting base plate;

[0021] a lifting member connected to the mounting bracket; and

[0022] A positioning member is connected to the telescopic shaft of the lifting member and can be extended or retracted into the through hole along with the telescopic shaft.

[0023] By integrating lifting and positioning components, this solution automatically and precisely positions the module's center partitions. Driven by the lifting components, the positioning components automatically extend, facilitating the positioning and installation of the module's center partitions without manual intervention. This automated positioning method significantly improves assembly precision, reduces errors caused by manual operation, and ensures module accuracy and consistency throughout the production process. The lifting components' automated lifting and lowering motion allows for rapid positioning and removal, significantly reducing the time and complexity of manual operations.

[0024] In one embodiment of the present application, the splint includes:

[0025] a first plate body, the first plate body being slidably connected to the guide rail; and

[0026] The second plate is connected to the first plate and can abut against the battery core.

[0027] The first plate slides along the guide rails, allowing the clamping plate to be flexibly adjusted to the varying sizes of cells or modules. This sliding design allows the clamping plate to quickly adapt to varying cell sizes without changing trays, thereby increasing production line flexibility and efficiency. Through sliding adjustment, the clamping plate can be precisely moved closer to or further away from the cell, ensuring accurate clamping during every production operation.

[0028] In one embodiment of the present application, reinforcing ribs are provided between the first and second plates. The reinforcing ribs herein serve to increase the structural strength between the first and second plates. The support provided by the reinforcing ribs provides a more stable connection between the two plates, effectively withstanding greater clamping forces and external pressure without deformation. The reinforcing ribs significantly enhance the overall strength of the splint, ensuring its stability during extended use and extending its service life.

[0029] The above technical solution, with its adjustable clamping plate design, allows for the creation of a suitable clamping zone simply by adjusting the position of the clamping plate, eliminating the need to replace the pallet. This significantly increases the pallet's flexibility, enabling it to quickly adapt to the production needs of modules of varying specifications, reducing the time and manual labor associated with frequent pallet changes and improving production line efficiency. Furthermore, it not only enhances the level of automation in the production process but also improves assembly precision and efficiency, avoiding the potential positioning errors associated with manual installation.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0036] like Figures 1 to 3 As shown, in order to achieve the above purpose, the present invention proposes an automatically changeable pallet, comprising:

[0037] The supporting base plate 10 is provided with a through hole;

[0038] A guide rail 21 connected to the support base 10;

[0039] At least two clamping plates, when there are two clamping plates, the two clamping plates are connected to the guide rail 21 and can move closer to or farther from each other along the length direction of the guide rail 21 to form clamping areas of different sizes between the two clamping plates; and

[0040] The lifting assembly has a positioning piece 53 and is disposed in the through hole. When the clamping area clamps the battery cell to form a first module, the lifting assembly extends out of the through hole so that the middle partition 60 in the first module is plugged into the positioning piece 53 .

[0041] Specifically, the support base plate 10 is provided with a through hole, the lifting assembly is located below the support base plate 10, and the guide rail 21 is connected to the support base plate 10 and arranged along the length of the support base plate 10. It is used to provide a smooth moving track for the clamping plate, allowing the clamping plate to move back and forth along the rail during the production process, thereby ensuring the clamping plate's moving path is accurate and stable.

[0042] The splint is the part of the pallet that comes into direct contact with the battery cell or module, and the pallet system requires at least two splints. When there are two splints, they are respectively mounted on the guide rail 21 and can move along the length of the rail. The splints move relative to each other through the guiding action of the rail, moving closer to or away from each other, thereby forming clamping areas of different sizes between the two splints for fixing and clamping battery cell modules of different specifications. During operation, the splints can be adjusted automatically without human intervention, and precise adjustment can be achieved through the guide rail 21, allowing the pallet system to quickly adapt to the production needs of modules of different specifications.

[0043] The lifting assembly is installed below the supporting base plate 10, and is a lifting mechanism with a positioning member 53. The lifting assembly extends through the through hole on the supporting base plate 10 and is used for the installation and positioning of the middle partition 60. When the first module is clamped in the clamping area, the lifting member 52 extends to ensure the accurate insertion and positioning of the middle partition 60 through the positioning member 53. The lifting function of the lifting assembly enables the tray to have vertical adjustment capabilities during the assembly process, and the system can automatically complete the installation of the middle partition 60, greatly improving production efficiency and accuracy. The first module in this application is a large module that needs to be installed with the middle partition 60.

[0044] The above technical solution, with its adjustable clamping plate design, allows for the creation of a suitable clamping zone simply by adjusting the position of the clamping plate, eliminating the need to replace the pallet. This significantly increases the pallet's flexibility, enabling it to quickly adapt to the production needs of modules of varying specifications, reducing the time and manual labor associated with frequent pallet changes and improving production line efficiency. Furthermore, it not only enhances the level of automation in the production process but also improves assembly precision and efficiency, avoiding the potential positioning errors associated with manual installation.

[0045] In one embodiment of the present application, the guide rails 21 are arranged above the supporting base plate 10, and a gasket bar 40 for supporting the battery cell is provided between the guide rails 21, and the horizontal height of the gasket bar 40 is the same as the horizontal height of the guide rails 21.

[0046] Specifically, the guide rail 21 is located above and tightly connected to the support base 10. The guide rail 21 guides the sliding of the clamping plate, allowing it to move back and forth along the length of the rail on the support base 10. The guide rail 21 provides a smooth and accurate track for the clamping plate's movement. The design of the guide rail 21 not only plays a key role in ensuring the clamping plate's precise movement but also ensures that the tray can be smoothly adjusted during use to accommodate modules of varying sizes.

[0047] The backing strip 40 is located in the middle of the guide rail 21 and directly contacts the battery cells, supporting and protecting them during pallet transport or assembly. The backing strip 40 provides a stable, even surface for the battery cells, preventing them from directly contacting the support base 10 or other hard components, thus reducing the risk of damage. It also helps stabilize the battery cells on the pallet, preventing them from shifting due to pallet movement or vibration.

[0048] The height of the gasket strip 40 is consistent with the height of the guide rail 21, ensuring that the battery cells are evenly stressed in the tray and preventing the battery cells from tilting or becoming unstable during transportation and assembly.

[0049] Using this technical solution, the backing strip 40 provides a stable and steady support surface for the battery cell, preventing it from directly contacting the hard base plate, thereby reducing the risk of damage during production and transportation. The backing strip 40 maintains the same height as the guide rail 21, ensuring the balance of the battery cell during clamping.

[0050] In one embodiment of the present application, a positioning post 34 is provided on one side of the clamping plate close to the battery cell, and the positioning post 34 can be inserted into the positioning hole of the battery cell module end plate 70 .

[0051] Specifically, the positioning posts 34 are the parts of the clamping plate that directly contact the cell module end plate 70. Their primary function is to plug into the positioning holes on the cell module end plate 70 to secure and position the cell module end plate 70. The positioning posts 34 work in conjunction with the positioning holes on the cell module end plate 70, preventing the module end plate 70 from shifting or tilting on the tray.

[0052] The end plates 70 of the cell module are provided with positioning holes specifically for use with the positioning posts 34 on the clamping plate. The end plates 70 are one of the key structural components of the cell module, located at both ends of the module, and play a role in protection and structural reinforcement.

[0053] The above-mentioned technical solution, in which the positioning posts 34 are plugged into the positioning holes, greatly improves the installation accuracy of the module end plate 70. This physical structure allows the module end plate 70 to be precisely positioned during loading, preventing displacement or tilting of the module end plate 70 due to vibration or movement.

[0054] In one embodiment of the present application, rail clamps 22 are provided at both ends of the guide rail 21 .

[0055] With the above technical solution, the guide rail clamps 22 are arranged at both ends of the guide rail 21, which can effectively limit the splint from moving out of the guide rail 21, thereby improving the safety of the splint during operation.

[0056] In one embodiment of the present application, the lifting assembly includes:

[0057] A mounting bracket 51 is connected to the bottom of the supporting base plate 10;

[0058] A lifting member 52 connected to the mounting bracket 51; and

[0059] The positioning member 53 is connected to the telescopic shaft of the lifting member 52 and can be extended or retracted into the through hole along with the telescopic shaft.

[0060] Specifically, the mounting bracket 51 is located at the bottom of the support base 10 and serves to securely hold the lift 52. Attached to the underside of the support base 10, the mounting bracket 51 provides a stable support structure, enabling the lift 52 to move up and down with stability. The primary function of the mounting bracket 51 is to securely mount the lift 52 within the pallet system, ensuring it does not shift or become loose during operation.

[0061] The lifter 52 controls the lifting and lowering motion of the positioning member 53 via a telescopic shaft. Connected to the support base 10 via the mounting bracket 51, the lifter 52 is responsible for moving the positioning member 53 up and down, thereby inserting and retracting the cell module's center separator 60. The lifter 52 typically employs an electric or pneumatic telescopic design, enabling precise control of the height and position of the positioning member 53. The telescopic motion of the lifter 52 is controlled by an external control system, ensuring its stability and controllability.

[0062] The positioning member 53 is connected to the telescopic shaft of the lifting member 52 and is the component that directly contacts and positions the module. The positioning member 53 extends and retracts through the hole in the support base 10 as the lifting member 52 moves. When the lifting member 52 is in operation, the positioning member 53 extends from the tray base and enters the module, precisely positioning the central partition 60 within the module. When not in use, the positioning member 53 retracts below the support base 10 to avoid interfering with the loading of other modules of different specifications.

[0063] The above-described technical solution, through the coordinated operation of the lifting member 52 and the positioning member 53, can automatically and precisely position the center partition 60 in the module. Driven by the lifting member 52, the positioning member 53 automatically extends, facilitating the positioning and installation of the module's center partition 60 without the need for manual intervention. This automated positioning method greatly improves assembly accuracy, reduces errors caused by manual operation, and ensures the accuracy and consistency of the modules during production. The lifting member 52's automatic lifting action enables the rapid positioning and removal of the positioning member 53, significantly reducing the time and complexity of manual operation.

[0064] In one embodiment of the present application, the splint includes:

[0065] A first plate 31 slidably connected to the guide rail 21 ; and

[0066] The second plate 32 is connected to the first plate 31 and can abut against the battery cell.

[0067] Using this technical solution, the first plate 31 slides along the guide rail 21, allowing the clamping plate to be flexibly adjusted to the varying sizes of battery cells or modules. This sliding design allows the clamping plate to quickly adapt to varying battery cell sizes without the need to change trays, thereby improving the flexibility and efficiency of the production line. Through sliding adjustment, the clamping plate can be precisely moved closer to or further away from the battery cell, ensuring accurate clamping during every production operation.

[0068] In one embodiment of the present application, a reinforcing rib 33 is provided between the first plate 31 and the second plate 32 .

[0069] Using the above technical solution, the reinforcing ribs 33 in this application serve to increase the structural strength between the first plate 31 and the second plate 32. The support provided by the reinforcing ribs 33 provides a more stable connection between the two plates, effectively withstanding greater clamping forces and external pressure without deformation. The design of the reinforcing ribs 33 significantly enhances the overall strength of the splint, ensuring its stability during extended use and extending its service life.

[0070] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
