[0002] In the field of battery technology, the battery cell is the core component for energy storage and output, and the performance of its outer casing structure directly affects the safety, service life and overall performance of the battery cell.

[0003] In the production process of pouch batteries, the encapsulation of irregularly shaped cells places special requirements on hot pressing molds. Traditional hot pressing molds often have a fixed structure. Changing molds for irregularly shaped cells is cumbersome and time-consuming. Furthermore, it is difficult to ensure uniform pressure distribution during hot pressing, which affects encapsulation quality and production efficiency. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-change structure for hot-pressing molds for packaging irregularly shaped cells of soft-pack batteries to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: a quick-change structure for hot-pressing molds for packaging irregularly shaped cells of soft-pack batteries, including a base and an irregularly shaped module. The side of the irregularly shaped module is provided with a wavy texture. The upper end of the base is provided with an installation groove. The bottom of the irregularly shaped module is provided with an installation block that slides with the installation groove. The installation groove is provided with a positioning component for keeping the irregularly shaped module stationary in one position.

[0006] Preferably, the positioning component includes a positioning groove formed inward on the side wall of the mounting groove, an L-shaped groove formed inward on the mounting block, an L-shaped slider slidably disposed in the L-shaped groove, and an elastic element provided between the L-shaped slider and the side wall of the L-shaped groove.

[0007] Preferably, the elastic element is a compression spring.

[0008] Preferably, the sidewalls of the slider and the sidewalls of the positioning groove are provided with mutually cooperating permanent magnets.

[0009] Preferably, the height of the sidewall of the positioning groove is lower than the height of the sidewall of the mounting groove.

[0010] Preferably, the mounting block has a stop at its upper end, and the stop is connected to the side wall of the irregularly shaped module.

[0011] This utility model has the following beneficial effects:

[0012] 1. The quick-change structure of the hot-pressing mold for packaging irregularly shaped cells of soft-pack batteries enables quick assembly and disassembly of irregularly shaped modules relative to the base through the sliding cooperation between the mounting block and the mounting groove. When changing different irregularly shaped modules, it is only necessary to push or pull the irregularly shaped module to make the mounting block slide out of the mounting groove along the direction of the mounting groove. This solves the problem of cumbersome and time-consuming mold replacement in traditional methods, realizes the quick replacement of hot-pressing molds for irregularly shaped cells, improves production efficiency, and fixes the irregularly shaped module after it is in place to prevent slippage.

[0013] 2. The positioning component includes a positioning groove formed inward on the side wall of the mounting slot, an L-shaped groove formed inward on the mounting block, an L-shaped slider slidably disposed within the L-shaped groove, and an elastic element between the L-shaped slider and the side wall of the L-shaped groove. In its natural state, the elastic element pushes the L-shaped slider, causing one end to extend out of the L-shaped groove and embed into the positioning groove, thus mechanically engaging and fixing the mounting block and the irregular module. When changing the mold, an external force is applied, such as pulling or pushing the L-shaped slider, to compress the elastic element, causing the L-shaped slider to exit the positioning groove. At this time, the mounting block can slide freely along the mounting slot, realizing the disassembly or displacement of the irregular module. Through the cooperation of the elastic element and the L-shaped slider, automatic engagement and external force unlocking of the positioning are achieved, and positioning and release can be completed without additional tools, further simplifying the quick change operation. The mechanical engagement structure is stable, ensuring that the irregular module will not shift due to pressure or vibration during the hot pressing process, thus ensuring the packaging accuracy.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0021] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0022] Example 1:

[0023] A quick-change structure for hot-pressing molds for packaging irregularly shaped cells in a soft-pack battery includes a base 1 and an irregularly shaped module 2. The irregularly shaped module 2 is a hot-pressing forming component that matches the contour of the irregularly shaped cell. It is made of Cr12 mold steel with a chrome-plated surface. The sides of the irregularly shaped module 2 have a wavy texture, which enhances the fit with the edge of the cell packaging during hot pressing, helps to distribute pressure evenly, and improves the packaging quality. The upper end of the base 1 has a mounting groove 3, and the bottom of the irregularly shaped module 2 has a mounting block 4 that slides with the mounting groove 3. The gap between the mounting block 4 and the mounting groove 3 is 0. The mounting groove 3 is equipped with a positioning component 5 to keep the irregularly shaped module 2 stationary in one position. Through the sliding cooperation between the mounting block 4 and the mounting groove 3, the irregularly shaped module 2 can be quickly installed and removed from the base 1. When changing different irregularly shaped modules 2, it is only necessary to push or pull the irregularly shaped module 2 to make the mounting block 4 slide out of the mounting groove 3 along the direction of the mounting groove 3. This solves the problem of cumbersome and time-consuming mold replacement in traditional mold replacement, realizes the rapid replacement of irregularly shaped battery cell hot pressing mold, and improves production efficiency. The positioning component 5 fixes the irregularly shaped module 2 after it is in place to prevent it from sliding.

[0024] In this embodiment, the positioning component 5 includes a positioning groove 51 formed inward on the side wall of the mounting groove 3, and an L-shaped groove 52 formed inward on the mounting block 4. An L-shaped slider 53 is slidably disposed in the L-shaped groove 52. An elastic element 54 is provided between the L-shaped slider 53 and the side wall of the L-shaped groove 52. In its natural state, the elastic element 54 pushes the L-shaped slider 53 so that one end extends out of the L-shaped groove 52 and is embedded in the positioning groove 51. The mounting block 4 and the irregular module 2 are fixed by mechanical engagement. When changing the mold, an external force is applied, such as pulling or pushing the L-shaped slider 53, to compress the elastic element 54. The L-shaped slider 53 exits the positioning groove 51. At this time, the mounting block 4 can slide freely along the mounting groove 3 to realize the disassembly or displacement of the irregular module 2. Through the cooperation of the elastic element 54 and the L-shaped slider 53, the automatic engagement and external force unlocking of the positioning are realized. Positioning and release can be completed without additional tools, further simplifying the quick change operation. The mechanical engagement structure is stable, ensuring that the irregular module 2 will not shift due to pressure or vibration during the hot pressing process, thus ensuring the packaging accuracy.

[0025] It should be noted that the material is 45# steel, with the part extending 5mm out of the L-shaped groove 52 and embedded in the positioning groove 51 to a depth of 4-5mm.

[0026] In this embodiment, the elastic element 54 is a compression spring. When the compression spring extends naturally, it applies a pushing force to the L-shaped slider 53, causing a portion of it to embed into the positioning groove 51. The compression spring is low in cost, wear-resistant, and easy to replace, making it suitable for industrial mass production scenarios and reducing equipment maintenance costs.

[0027] In this embodiment, the sidewall of the slider and the sidewall of the positioning groove 51 are provided with mutually cooperating permanent magnets 6. The permanent magnets 6 are made of neodymium iron boron and have a magnetic force of 8N. When unlocking, an external force of more than 12N is applied. When the side of the L-shaped slider 53 is pushed close to the sidewall of the positioning groove 51 by the elastic member 54, the permanent magnets 6 attract each other, which enhances the binding force between the slider and the positioning groove 51. This makes it necessary to overcome both the elastic force of the elastic member 54 and the magnetic force of the permanent magnets 6 when disassembling, so as to prevent the irregular module 2 from accidentally falling out of the positioning due to slight vibration, and further improve the fixing strength. It is especially suitable for scenarios with high-frequency vibration during hot pressing.

[0028] In this embodiment, the height of the side wall of the positioning groove 51 is lower than the height of the side wall of the mounting groove 3, so as to avoid the positioning groove 51 interfering with the sliding trajectory of the mounting block 4 due to excessive height.

[0029] In this embodiment, the upper end of the mounting block 4 is provided with a stop block 7, which is connected to the side wall of the irregular module 2. The stop block 7 can be used to abut against other sides of the irregular battery cell to improve the stability of the irregular battery cell during installation.

[0030] The working principle of this utility model is as follows: The quick-change structure of the hot-pressing mold for packaging irregularly shaped cells of soft-pack batteries includes a base 1 and an irregularly shaped module 2. The side of the irregularly shaped module 2 is provided with a wavy texture, which can enhance the fit with the edge of the cell packaging during hot pressing, help to distribute pressure evenly, and improve the packaging quality. The upper end of the base 1 is provided with a mounting groove 3, and the bottom of the irregularly shaped module 2 is provided with a mounting block 4 that slides with the mounting groove 3. The mounting groove 3 is provided with a positioning component 5 for keeping the irregularly shaped module 2 stationary in one position. Through the sliding cooperation between the mounting block 4 and the mounting groove 3, the irregularly shaped module 2 can be quickly disassembled and assembled relative to the base 1. When changing different irregularly shaped modules 2, it is only necessary to push or pull the irregularly shaped module 2 to make the mounting block 4 slide out of the mounting groove 3 along the direction of the mounting groove 3, which solves the problem of cumbersome and time-consuming mold replacement in traditional methods and realizes the hot-pressing mold for irregularly shaped cells. The quick change of the tool improves production efficiency. After the irregular module 2 is in place, the positioning component 5 fixes it to prevent slippage. When using the positioning component 5, in its natural state, the elastic element 54 pushes the L-shaped slider 53 so that one end of it extends out of the L-shaped groove 52 and is embedded in the positioning groove 51. The mounting block 4 and the irregular module 2 are fixed by mechanical engagement. When changing the mold, an external force is applied, such as pulling or pushing the L-shaped slider 53, to compress the elastic element 54. The L-shaped slider 53 exits the positioning groove 51. At this time, the mounting block 4 can slide freely along the mounting groove 3 to realize the disassembly or displacement of the irregular module 2. Through the cooperation of the elastic element 54 and the L-shaped slider 53, the automatic engagement and external force unlocking of the positioning are realized. Positioning and release can be completed without additional tools, further simplifying the quick change operation. The mechanical engagement structure is stable and ensures that the irregular module 2 will not shift due to pressure or vibration during the hot pressing process, thus ensuring the packaging accuracy.

[0031] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
