Description

Technical Field

[0001] This utility model relates to the field of lithium battery module manufacturing technology, and in particular to an anti-tipping device for mounting the end plate of a battery cell module. Background Technology

[0002] With the increasing prevalence of CTP (cell-to-pack) battery packs and the continuous advancement of battery technology, traditional module production lines are facing the need for transformation. On traditional module production lines, each module is equipped with end plates and side plates, designs intended to provide stability and safety. However, the CTP process eliminates the need for side plates. Therefore, for established production lines, improving the fixation effect of the end plates without completely rebuilding the line has become a significant challenge.

[0003] Modifying existing legacy production lines is complex and often requires large-scale redesign to meet the requirements of CTP (Cell-to-Pack) technology. Partial modifications and system upgrades have become more economical and feasible solutions. By rationally designing and installing new fixing devices or improving end-plate fixing mechanisms, the fixation effect of end plates in CTP production lines can be optimized from the existing structure, ensuring the stability and safety of the production process. These improvements not only enhance the utilization efficiency of existing equipment but also help reduce production costs, thus better adapting to the latest demands of the battery industry. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. In order to achieve the above purpose, an anti-tipping device is installed on the end plate of the battery cell module to solve the problems mentioned in the background technology.

[0005] An anti-tipping device is installed on the end plate of a battery cell module, comprising: End plate tooling plate, fixed to the cell module tray; Positioning and correction parts are installed on both sides of the end plate tooling plate; At least two end plate positioning mechanisms are embedded in the end plate tooling plate; An elastic component is provided on the end plate positioning mechanism and connected between the two end plate positioning mechanisms; Among them, the distance between the two end plate positioning mechanisms is adjusted by connecting them through elastic components, which clamps and adapts to end plates of different lengths of battery cell modules.

[0006] As a further embodiment of this utility model: the end plate tooling plate is provided with a groove, and the end plate positioning mechanism is installed in the groove. Installing all end plate positioning mechanisms in the grooves of the end plate tooling plate makes the entire mechanism structure more compact and more integrated, ensuring the stability and reliability of the movement of each component, while also facilitating installation and maintenance.

[0007] As a further embodiment of this invention: the positioning and correction part is connected to the end plate tooling plate by bolts. The bolt connection method makes the adjustment of the positioning and correction hole simple and reliable, the threaded transmission force control precise, and the scale markings make manual adjustment intuitive and efficient, reducing debugging time and errors.

[0008] As a further aspect of this utility model: the end plate positioning mechanism, under the action of the elastic component, adapts to module end plates of different sizes and adjusts the distance between the two end plate positioning mechanisms. The adjustable distance between the end plate positioning mechanisms, under the action of the elastic component, allows one set of tooling to be compatible with module end plates of various specifications, greatly improving the equipment versatility and production flexibility of old production lines, and reducing the modification costs required for product changeovers.

[0009] As a further embodiment of this invention: the end plate positioning mechanism includes a rolling pin, an end plate positioning pin, and a mounting plate. Specifically, it adopts a combination structure of the rolling pin, the positioning pin, and the mounting plate. The rolling pin may be used to reduce sliding friction to make adjustment easier, and the positioning pin is used to accurately position the end plate hole. This design makes the positioning function more accurate and reliable.

[0010] As a further embodiment of this utility model: the end plate tooling plate is provided with a slot for mounting the end plate positioning mechanism. The specific slot provides precise guidance and limitation for the sliding of the end plate positioning mechanism, ensuring that the two mechanisms always move smoothly in the predetermined direction, avoiding skewness and jamming, and ensuring the accuracy of the action.

[0011] As a further embodiment of this invention: the positioning and correction part is provided with a threaded structure and scale markings, and visually readable position correction can be achieved by adjusting with screws. This directly clarifies the function of the scale markings for visually assisted adjustment, highlighting the humanized and easy-to-operate design advantages of the mechanism and reducing the technical requirements for operators.

[0012] As a further aspect of this invention: the elastic component connects two end plate positioning mechanisms and provides continuous pressure during end plate installation to prevent the end plates from tipping over. This emphasizes the core function of the spring mechanism in providing continuous pressure throughout installation and transportation, clarifies its crucial role in "preventing tipping during transportation," and highlights the practical value of this invention.

[0013] Compared with the prior art, the present invention has the following technical advantages: By employing the above technical solution, through the end plate tooling plate for fixing on the module tray, the positioning and correction part with scale and threads for visual adjustment, the end plate positioning mechanism that can be slidably embedded in the tooling plate, and the elastic component that connects the two positioning mechanisms and provides elastic clamping force, it achieves precise positioning and reliable clamping of end plates of different sizes in the new production line process that eliminates the module side plates, effectively preventing them from tipping over during transportation and pressurization, through the cooperation of the positioning mechanism with adjustable spacing and continuous spring force.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figure 1 In this embodiment of the utility model, an anti-tipping device is installed on the end plate of a battery cell module, comprising: End plate tooling plate 1, fixed to the cell module tray; Specifically, such as Figure 2 As shown, the diagram is a schematic diagram of the end plate fixture plate; the end plate fixture plate 1 is used to fix the entire mechanism module pallet mounting plate 33, and to fix other anti-tipping mechanism components; Positioning and correction parts 2 are provided on both sides of the end plate tooling plate 1; In this embodiment, the positioning and correction part 2 is provided with a threaded structure and scale markings, and the position correction can be visually readable by adjusting the screws.

[0018] At least two end plate positioning mechanisms 3 are embedded in the end plate tooling plate 1; An elastic component 4 is provided on the end plate positioning mechanism 3 and connected between the two end plate positioning mechanisms 3; Among them, the distance is adjusted by connecting the elastic component 4 between the two end plate positioning mechanisms 3, and clamping and adapting to the end plates of battery cell modules of different lengths.

[0019] In this embodiment, the end plate tooling plate 1 is provided with a groove 10, and the end plate positioning mechanism 3 is installed in the groove 10.

[0020] Specifically, the end plate positioning mechanism 3 is embedded inside the end plate tooling plate 1 and can slide in one direction for appropriate adjustment.

[0021] In this embodiment, the positioning and correction part 2 is connected to the end plate tooling plate 1 by bolts.

[0022] In this embodiment, as Figure 3 As shown, the diagram illustrates an end-plate positioning mechanism. Under the action of the elastic component 4, the end-plate positioning mechanism 3 adapts to module end plates of different sizes, adjusting the distance between the two end-plate positioning mechanisms 3. The end-plate positioning mechanism 3 includes a rolling pin 31, an end-plate positioning pin 32, and a mounting plate 33.

[0023] In this embodiment, the end plate tooling plate 1 is provided with a slot 30 for mounting the end plate positioning mechanism 3.

[0024] In this embodiment, the elastic component 4 connects the two end plate positioning mechanisms 3 and provides continuous pressure during the end plate installation process to prevent the end plate from tipping over.

[0025] The following describes the working principle and process of the embodiments disclosed in this utility model: First, the end plate positioning mechanism 3 is adjusted manually according to the size of the end plate, mainly through visual adjustment of the screws of the end plate straightening mechanism; Then, after the module is put into production, when installing the end plate, the operator can manually adjust the distance of the end plate positioning mechanism 3 according to the hole positions on the end plate to install the end plate onto the end plate positioning mechanism 3. Since the spring exerts a certain pressure on the end plate positioning mechanism 3, this will ensure that the end plate will not tip over during transportation.

[0026] Finally, the module is pressurized and shaped at the pressure forming station. After being transported to the module off-line, the end plate tooling plate 1 is unlocked by the rail lock, completing the module production.
