[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for 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 this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0025] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figures 1-7 As shown, the soft-pack battery cold and hot pressing device of this utility model embodiment has a first direction x, a second direction y, and a third direction z that are perpendicular to each other, and includes: a first driving unit 1, a second driving unit 2, a cold pressing component 3, and a hot pressing component 4. The first driving unit 1 can drive the cold pressing component 3 to cold press the soft-pack battery 5, and the second driving unit 2 can drive the hot pressing component 4 to hot press the soft-pack battery 5.

[0027] The first drive unit 1 includes a first drive component 11 and a first pressure sensor 12. The power output end of the first drive component 11 is connected to the first pressure sensor 12 along the second direction y.

[0028] The second drive unit 2 is disposed on one side of the first drive unit 1 along the first direction x. The second drive unit 2 includes a second drive member 21 and a second pressure sensor 22. The power output end of the second drive member 21 is connected to the second pressure sensor 22 along the second direction y.

[0029] The cold pressing assembly 3 is installed on the side of the first pressure sensor 12 that is away from the first drive component 11.

[0030] The hot-pressing assembly 4 is installed on the side of the second pressure sensor 22 opposite to the second drive member 21.

[0031] During operation, the first driving component 11 drives the cold pressing component 3 to apply pressure to the dispensing position of the soft-pack battery 5 along the second direction y. At this time, the first pressure sensor 12 detects the cold pressing pressure at the dispensing position. The second driving component 21 drives the hot pressing component 4 to apply pressure to the dispensing position of the soft-pack battery 5 along the second direction. At this time, the second pressure sensor 22 detects the hot pressing pressure at the dispensing position.

[0032] The adhesive application points for the pouch battery 5 are as follows: After the aluminum-plastic composite film of the pouch battery 5 is encapsulated, adhesive needs to be applied to its cut edges (especially the four perimeter edges) to form an adhesive layer covering the sharp cut of the aluminum-plastic film; the solder joints of the tabs and wires of the pouch battery 5 need to be covered with tab adhesive. The adhesive layer wraps the solder joints inside the tab adhesive to prevent the solder joints from oxidizing or falling off due to external force, while also improving mechanical strength. In addition, the tab adhesive extends to the aluminum-plastic film encapsulation area to ensure that the root of the tab is tightly bonded to the encapsulation film and to prevent electrolyte leakage.

[0033] Based on the above structural configuration, the cold pressure at the dispensing position is detected by the first pressure sensor 12, and the hot pressure at the dispensing position is detected by the second pressure sensor 22. This facilitates precise pressure application and avoids damage to the soft-pack battery 5.

[0034] like Figure 1 As shown, in some embodiments, a support frame 6 is also included, which is mounted below the first drive unit 11 and the second drive unit 21 along a third direction z. Thus, the support frame 6 can provide support for the first drive unit 1 and the second drive unit 2 to ensure smooth operation of the cold pressing assembly 3 and the hot pressing assembly 4.

[0035] like Figure 1 As shown, in some embodiments, a placement frame 7 is also included, and each pouch battery 5 is fixed to the placement frame 7 along the first direction x. Specifically, the placement frame 7 has a fixing groove for fixing the position of the pouch battery 5, or a positioning fixture is provided on the placement frame 7 for fixing the position of the pouch battery 5, thereby ensuring that the position of the pouch battery 5 is stable when the cold pressing assembly 3 performs cold pressing and the hot pressing assembly 4 performs hot pressing.

[0036] like Figure 2 As shown, in some embodiments, the first driving unit 1 further includes a first slider 13, which is mounted on the first driving unit 11. The first pressure sensor 12 is slidably connected to the first slider 13 along the second direction y. Specifically, the first slider 13 includes a first slide rail 131 and a first slider 132. The first slide rail 131 is mounted on the first driving unit 11, and the first slider 132 is slidably connected to the first slide rail 131 along the second direction y. The first pressure sensor 12 is mounted on the first slider 132. Thus, the first driving unit 11 smoothly drives the first pressure sensor 12 to move along the second direction y through the first slider 13, thereby driving the cold pressing assembly 3 to move smoothly.

[0037] like Figure 4As shown, in some embodiments, the second driving unit 2 further includes a second slider 23, which is mounted on the second driving unit 21. The second pressure sensor 22 is slidably connected to the second slider 23 along the second direction y. Specifically, the second slider 23 includes a second slide rail 231 and a second slider 232. The second slide rail 231 is mounted on the second driving unit 21, and the second slider 232 is slidably connected to the second slide rail 231 along the second direction y. The second pressure sensor 22 is mounted on the second slider 232. Thus, the second driving unit 21 smoothly drives the second pressure sensor 22 to move along the second direction y through the second slider 23, thereby driving the hot-pressing assembly 4 to move smoothly.

[0038] like Figure 2 As shown, the first drive unit 1 further includes a third slider 14, which is slidably connected to the first slider 13 along the second direction y. The cold pressing assembly 3 is mounted on the third slider 14. Specifically, the third slider 14 includes a third slide rail 141, a third slider 142, and a first mounting plate 143. The third slide rail 141 is slidably connected to the first slider 13 along the second direction y, and the third slider 142 is slidably connected to the third slide rail 141 along the second direction y. The first mounting plate 143 is mounted on the third slider 142 along the third direction z and is located on the side of the first pressure sensor 12 opposite to the first drive unit 11. The cold pressing assembly 3 is mounted on the side of the first mounting plate 143 opposite to the first pressure sensor 12. In this way, the movement range of the cold pressing assembly 3 along the second direction y can be increased by the third slider 14, while ensuring a compact structure and reducing space occupation.

[0039] like Figure 4 As shown, the second drive unit 2 further includes a fourth slider 24, which is slidably connected to the second slider 23 along the second direction y. The hot-pressing assembly 4 is mounted on the fourth slider 24. Specifically, the fourth slider 24 includes a fourth slide rail 241, a fourth slider 242, and a second mounting plate 243. The fourth slide rail 241 is slidably connected to the second slider 23 along the second direction y, and the fourth slider 242 is slidably connected to the fourth slide rail 241 along the second direction y. The second mounting plate 243 is mounted on the fourth slider 242 along the third direction z and is located on the side of the second pressure sensor 22 opposite to the second drive unit 21. The hot-pressing assembly 4 is mounted on the side of the second mounting plate 243 opposite to the second pressure sensor 22. Thus, the fourth slider 24 can increase the movement range of the hot-pressing assembly 4 along the second direction y, while ensuring a compact structure and reducing space occupation.

[0040] In one specific embodiment, the first driving member 11 and the second driving member 21 are pneumatic cylinders, hydraulic cylinders, or electric push rods. The piston rod of the pneumatic cylinder, the piston rod of the hydraulic cylinder, or the telescopic rod of the electric push rod serves as the power output end, thereby stably providing thrust.

[0041] like Figure 2 As shown, in some embodiments, the first drive unit 1 further includes a third pressure sensor 15 and a first connecting plate 16. The third pressure sensor 15 is connected to the first pressure sensor 12 via the first connecting plate 16, and the third pressure sensor 15 is located on the side of the first mounting plate 143 facing away from the cold pressing assembly 3. Thus, when the cold pressing assembly 3 cold presses the pouch battery 5, the first pressure sensor 12 and the third pressure sensor 15 can simultaneously detect the pressure applied by the cold pressing assembly 3, improving device detection redundancy.

[0042] like Figure 4 As shown, in some embodiments, the second drive unit 2 includes a fourth pressure sensor 25 and a second connecting plate 26. The fourth pressure sensor 25 is connected to the second pressure sensor 22 via the second connecting plate 26, and the fourth pressure sensor 25 is located on the side of the second mounting plate 243 facing away from the hot-pressing assembly 4. Thus, when the hot-pressing assembly 4 hot-presses the pouch battery 5, the second pressure sensor 22 and the fourth pressure sensor 25 can simultaneously detect the pressure applied by the hot-pressing assembly 4, improving device detection redundancy.

[0043] like Figure 2 and Figure 4 As shown, in some embodiments, the third sliding member 14 further includes a first heat insulation block 144, through which the cold pressing assembly 3 is mounted on the first mounting plate 143; the fourth sliding member 24 further includes a second heat insulation block 244, through which the hot pressing assembly 4 is mounted on the second mounting plate 243. Exemplarily, the first heat insulation block 144 and the second heat insulation block 244 are made of resin material. By setting the first heat insulation block 144, the cold pressing assembly 3 can be insulated, ensuring the normal temperature of the third pressure sensor 15 and preventing damage; by setting the second heat insulation block 244, the hot pressing assembly 4 can be insulated, ensuring the normal temperature of the fourth pressure sensor 25 and preventing damage.

[0044] like Figure 3As shown, in some embodiments, the fourth slider 242 has a first mounting hole 2421 extending along a first direction x. A connector passing through the first mounting hole 2421 allows the fourth slider to be mounted on the second mounting plate 243. Since the first mounting hole 2421 extends along the first direction x, it facilitates adjusting the mounting position of the fourth slider 242 along the first direction x. The second heat insulation block 244 has a second mounting hole 2441 extending along a third direction z. A connector passing through the second mounting hole 2441 allows the second heat insulation block 244 to be mounted on the second mounting plate 243. Since the second mounting hole 2441 extends along the third direction z, it facilitates adjusting the mounting position of the second heat insulation block 244 along the third direction z. Correspondingly, the structure of the third slider 142 is the same as that of the fourth slider 242, and the structure of the first heat insulation block 144 is the same as that of the second heat insulation block 244. The mounting methods of the third slider 142 and the first heat insulation block 144 will not be described further here.

[0045] like Figure 6 As shown, in some embodiments, the hot pressing assembly 4 includes a heating plate 41, a hot pressing block 42, and a heating rod 44. The heating plate 41 is installed on the side of the second pressure sensor 22 away from the second driving member 21. The heating plate 41 has a through hole along the first direction x. The heating rod 44 is disposed in the mounting hole. The hot pressing block 42 is installed on the heating plate 41 and extends out of the side wall of the heating plate 41 along the second direction y. In this way, the heating plate 41 can be heated by the heating rod 44, which will eventually raise the temperature of the hot pressing block 42. The hot pressing block 42 is used to hot press the soft-pack battery 5.

[0046] In some embodiments, the hot pressing assembly further includes a first temperature sensor 43, which is mounted on the heating plate 41. Thus, the temperature sensor 43 is used to detect the internal temperature of the heating plate 41.

[0047] like Figure 7 As shown, in some embodiments, the cold pressing assembly 3 includes a cooling plate 31 and a cold pressing block 32. The cooling plate 31 has a cooling channel extending through it along a first direction x. The cooling plate 31 is mounted on the side of the first pressure sensor 12 opposite to the first driving member 11. The cold pressing block 32 is mounted on the cooling plate 31 and extends out of the sidewall of the cooling plate 31 along a second direction y. In this way, by connecting the cooling channel of the cooling plate 31 to the air pipe, the heat of the cooling plate 31 is carried away by the airflow, achieving a heat dissipation effect, so as to keep the cooling plate 31 at room temperature, thereby keeping the cold pressing block 32 at room temperature, for cold pressing of the pouch battery 5.

[0048] For example, the cooling plate 31 and the heating plate 41 are made of aluminum plates, and the cold pressing block 32 and the hot pressing block 42 are made of ceramic blocks.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
