[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Please refer to Figure 1 and Figure 2 This embodiment provides a hot pressing device 100 for hot pressing the film covering the top cover of the battery cell.

[0026] Specifically, the hot pressing equipment 100 includes an equipment body 10, a carrier 20, and a hot pressing mechanism 30. The carrier 20 is mounted on the equipment body 10 and is used to hold the battery cell. The hot pressing mechanism 30 includes a first driving member 31 and a hot pressing block 33. The first driving member 31 is mounted on the equipment body 10. The first driving member 31 and the hot pressing block 33 are connected by a drive mechanism and are used to drive the hot pressing block 33 to rise and fall to hot press the insulating parts of the battery cell. The hot pressing block 33 is provided with a clearance member for avoiding the battery cell terminals.

[0027] In this embodiment, the insulating component is an insulating film. During hot pressing, the battery cell with the insulating film covering its top cover is placed on the carrier 20, and the first driving component 31 drives the hot pressing block 33 to press down, fixing the insulating film to the top cover of the battery cell. Since the top cover of the battery cell faces upwards and the battery cell's terminals face the hot pressing block 33 when placed, by providing a clearance component on the hot pressing block 33, the hot pressing block 33 can avoid the battery cell's terminals, thus ensuring complete adhesion between the hot pressing block 33 and the top cover of the battery cell. This prevents warping of the film at the battery cell's terminals and avoids the formation of air bubbles, achieving complete adhesion between the hot pressing block 33 and the battery cell's terminals, thereby improving the adhesion quality of the top cover film and enhancing the quality of the battery cell product. It is understood that the insulating film is thin, flexible, and suitable for situations where the top cover of the battery cell has a complex curved surface.

[0028] Alternatively, in other embodiments, the insulating element can also be an insulating sheet. Insulating sheets are characterized by high mechanical strength and durability, and are suitable for applications requiring pressure resistance or mechanical protection. The specific structure of the insulating element can be set according to actual production conditions; this invention does not limit the specific type of insulating element.

[0029] Please refer to Figures 2-5 Specifically, the clearance component is a clearance groove 331. The clearance groove 331 is located on the side of the hot pressing block 33 facing the carrier 20. The clearance groove 331 is used to clear the terminal of the battery cell. During hot pressing, the terminal of the battery cell is positioned upwards, and the hot pressing block 33 moves downwards, allowing the terminal to enter the clearance groove 331. This ensures that the surface of the hot pressing block 33 is completely in contact with the surface of the battery cell top cover, thereby preventing warping of the film at the battery cell terminal position, preventing air bubbles, and improving the bonding quality of the battery cell top cover film. By providing the clearance groove 331 to cooperate with the terminal, direct contact between the hot pressing block 33 and the battery cell terminal is avoided, thus protecting the terminal.

[0030] Furthermore, the electrode post and the clearance groove 331 have the same shape and are in a clearance fit. There is a small gap between the electrode post and the clearance groove 331 so that the electrode post can enter or move out of the clearance groove 331 in the vertical direction, ensuring that the port of the clearance groove 331 can press against the bottom edge of the electrode post, so that the surface of the hot press block 33 is completely attached to the surface of the cell top cover, thereby avoiding warping of the film at the electrode post position, preventing air bubbles, and improving the bonding quality of the cell top cover film.

[0031] Furthermore, the depth of the clearance groove 331 is slightly greater than the height of the protrusion of the electrode relative to the surface of the cell top cover, so as to prevent the hot pressing block 33 from colliding with the electrode after being pressed down, thus protecting the electrode.

[0032] In this embodiment, the shape of the clearance groove 331 matches the shape of the pole post, ensuring a uniform gap between the clearance groove 331 and the pole post. This prevents excessive gaps that could cause the pole post to wobble, allowing the clearance groove 331 to precisely avoid the pole post and preventing mechanical interference between them. Specifically, in this embodiment, the pole post is a square post, and the clearance groove 331 is a square groove. By designing the pole post and clearance groove 331 as square structures, rotation of the pole post within the clearance groove 331 can be prevented, achieving directional installation and providing a foolproof effect, thus avoiding problems caused by incorrect installation posture of the hot press block 33. In other embodiments, the pole post and clearance groove 331 can be set to other shapes, such as circular or elliptical structures. This invention does not limit the shape of the pole post and clearance groove 331.

[0033] Please refer to Figure 2 The hot pressing mechanism 30 also includes a lower pressure plate 32. The lower pressure plate 32 is drively connected to the first driving member 31. The lower pressure plate 32 is disposed above the carrier 20. The hot pressing block 33 is disposed on the side of the lower pressure plate 32 facing the carrier 20. The first driving member 31 is used to drive the lower pressure plate 32 to move the hot pressing block 33 to hot press the insulating parts of the battery cell. By setting the lower pressure plate 32, the hot pressing block 33 below is kept in the same horizontal plane to synchronously hot press the battery cell on the carrier 20 below, so that the pressure of the hot pressing block 33 on the battery cell is uniform and uneven pressure distribution is avoided, which may cause damage to the battery cell.

[0034] Specifically, in this embodiment, the first driving component 31 is a cylinder. In other embodiments, the first driving component 31 may adopt other structures, such as a hydraulic cylinder or an electric cylinder. This utility model does not limit the specific structure of the first driving component 31.

[0035] Furthermore, the device body 10 is also provided with multiple vertically arranged guide posts. Multiple guide holes are provided on the lower pressure plate 32. The guide posts and guide holes cooperate to allow the lower pressure plate 32 to slide along the axial direction of the guide posts. By setting the lower pressure plate 32 and guide posts in cooperation, tilting of the lower pressure plate 32 during lifting and lowering is prevented, improving the bonding quality of the battery cell top cover film and further ensuring uniform pressure distribution of the hot pressing block 33 on the battery cell.

[0036] Furthermore, an elastic element 34 is provided between the hot pressing block 33 and the lower pressure plate 32. The elastic element 34 ensures balanced pressure on the hot pressing block 33. Specifically, as the lower pressure plate 32 descends, the elastic element 34 gradually compresses. Under the action of the elastic element 34, the hot pressing block 33 contacts the cell top cover film. As the first driving member 31 continues to push the lower pressure plate 32 downwards, the elastic element 34 is further compressed, and under the action of the elastic element 34, the hot pressing block 33 is tightly bonded to the surface of the cell top cover. It can be understood that by providing the elastic element 34, the hot pressing block 33 can remain in contact with the surface of the cell top cover throughout the hot pressing process. The bottom of the hot pressing block 33 remains in contact with the cell top cover under the action of the elastic element 34, improving the bonding quality of the cell top cover film and ensuring uniform overall hot pressing effect of the cell top cover film.

[0037] Furthermore, when there is a deviation in the position of the battery cell, the elastic element 34 is compressed to different degrees according to the force applied to compensate for the height difference. Specifically, in this embodiment, multiple battery cells are provided, and when the top covers of the multiple battery cells are located at different heights, the hot pressing block 33 is in contact with the top cover of the battery cell under the action of the elastic element 34. Furthermore, the end of the hot pressing block 33 connected to the elastic element 34 is located at different heights, while the end of the elastic element 34 connected to the lower pressure plate 32 is at the same height. Specifically, the elastic element 34 at the higher position of the hot pressing block 33 has a larger compression amount, while the elastic element 34 at the lower position of the hot pressing block 33 has a smaller compression amount. In other words, this embodiment, by providing the elastic element 34 between the lower pressure plate 32 and the hot pressing block 33, utilizes the expansion and contraction characteristics of the elastic element 34 to adapt to the uneven height of the top covers of multiple battery cells, achieving balanced hot pressing and improving hot pressing efficiency.

[0038] Specifically, the elastic element 34 is a spring. A telescopic guide rod is also provided between the hot pressing block 33 and the lower pressure plate 32. The spring is sleeved on the guide rod. It can be understood that the hot pressing block 33 and the lower pressure plate 32 are connected by the telescopic guide rod. The spring, connected between the hot pressing block 33 and the lower pressure plate 32, provides elastic cushioning when the hot pressing block 33 contacts the battery cell top cover film, preventing rigid contact between the hot pressing block 33 and the battery cell top cover film, thus avoiding damage. By providing the spring, the hot pressing block 33 remains in contact with the surface of the battery cell top cover during the hot pressing process, ensuring the uniformity of the overall hot pressing effect of the battery cell top cover film.

[0039] Furthermore, an elastic layer is also provided at the bottom of the hot pressing block 33. During the pressing process of the hot pressing block 33, the elastic layer comes into contact with the insulating film of the battery cell top cover, and the elastic layer is compressed and deformed. The elastic layer applies pressure to the battery cell top cover, thereby pressing the insulating film tightly onto the battery cell top cover. This applies uniform pressure to the insulating film, flexibly hot pressing the battery cell and avoiding damage or scratches to the battery cell. At the same time, it ensures that the adhesive of the insulating film can play its full role and improves the hot pressing effect.

[0040] Specifically, in this embodiment, the elastic layer is a fluororubber layer, which has excellent high-temperature resistance, insulation, and chemical stability. During use, the fluororubber layer can maintain stable elasticity and mechanical strength even at high temperatures, avoiding performance degradation due to material aging. Simultaneously, its excellent chemical stability can resist electrolyte residues that may come into contact with the material during hot pressing, ensuring long-term reliability and safety. In other embodiments, the elastic layer can be a silicone rubber layer, etc. This invention does not limit the specific type of the elastic layer.

[0041] In this embodiment, a heating element is embedded inside the hot pressing block 33 to heat the hot pressing block 33, enabling it to rapidly heat up to the operating temperature. A temperature detection element is also provided on the hot pressing block 33 to detect its temperature. Detecting the temperature of the hot pressing block 33 facilitates precise temperature control, preventing overheating or underheating. If the temperature of the hot pressing block 33 is insufficient, the heating element continues to heat it; when the temperature of the hot pressing block 33 reaches a preset value, the hot pressing block 33 presses against the top cover of the battery cell; if the temperature of the hot pressing block 33 is too high, the heating element stops heating to prevent deformation of the hot pressing block 33 or thermal runaway of the battery cell.

[0042] Furthermore, the hot pressing device 100 also includes a moving mechanism 40. The moving mechanism 40 is disposed on the device body 10. The carrier 20 is disposed on the moving mechanism 40. The moving mechanism 40 is used to move the carrier 20 so that the carrier 20 has at least a hot pressing station located directly below the hot pressing mechanism 30, and a standby station for pulling out the hot pressing mechanism 30. It can be understood that, in this embodiment, the carrier 20 is slidably connected to the device body 10 through the moving mechanism 40, and the carrier 20 can slide relative to the device body 10, thereby sliding into or out directly below the hot pressing mechanism 30. During hot pressing, the carrier 20 slides to the standby station, the battery cell covered with an insulating film is installed on the carrier 20, and then the carrier 20 is slid to the hot pressing station, where the hot pressing mechanism 30 hot presses the top cover film of the battery cell. By setting up the moving mechanism 40, the carrier 20 can slide out directly under the hot pressing mechanism 30, which makes it easier for technicians to install and replace battery cells, improves production efficiency, and allows technicians to stay away from the hot pressing station, thus improving equipment safety.

[0043] To improve hot pressing efficiency, in this embodiment, the carrier 20 is provided with multiple mounting slots 21. The hot pressing mechanism 30 includes multiple hot pressing blocks 33. When the carrier 20 is located directly below the hot pressing blocks 33, the mounting slots 21 are located directly below the hot pressing blocks 33, and each mounting slot 21 corresponds to one hot pressing block 33. During hot pressing, the bottom of the battery cell is inserted into the mounting slot 21, so that the top cover of the battery cell is exposed. The carrier 20 is moved to slide the battery cell directly below the hot pressing blocks 33, and the multiple hot pressing blocks 33 descend and hot press the corresponding battery cell below. By setting multiple mounting slots 21 and multiple hot pressing blocks 33, multiple battery cells can be hot pressed at one time, improving working efficiency.

[0044] Furthermore, multiple hot pressing blocks 33 are respectively installed below the lower pressure plate 32. The lower pressure plate 32 can drive the multiple hot pressing blocks 33 to move synchronously, so as to synchronously heat and press the battery cells below, and make the multiple hot pressing blocks 33 all located in the same horizontal plane, so as to achieve the effect of uniform heat and pressing of multiple battery cells and ensure that the pressure distribution of the hot pressing blocks 33 on the battery cells is uniform.

[0045] When there are deviations in the installation height of multiple battery cells, an elastic element 34 is set between the lower pressure plate 32 and the hot pressing block 33. The elastic element 34 can be compressed to different degrees according to the different heights of the battery cells, so as to always keep the hot pressing block 33 in contact with the top cover film of the battery cell, make up for the height difference, and adapt to the deviation of the battery cell installation position, the unevenness of the top cover of the battery cell, or the situation of hot pressing battery cells of different specifications and sizes at the same time.

[0046] Specifically, the moving mechanism 40 includes a guide rail 41 and a second driving member 42. The guide rail 41 is mounted on the device body 10. The carrier 20 is slidably connected to the guide rail 41. The second driving member 42 is used to drive the carrier 20 to slide along the guide rail 41. In this embodiment, the second driving member 42 is a linear cylinder. The second driving member 42 is drivenly connected to the carrier 20, causing the carrier 20 to slide along the guide rail 41.

[0047] In other embodiments, the second driving member 42 may adopt other types of driving structures, such as hydraulic cylinders or electric cylinders, and this utility model does not limit it in this regard.

[0048] In this embodiment, the moving mechanism 40 further includes a positioning detection element 43 to detect the position of the carrier 20. When the carrier 20 moves directly below the hot pressing mechanism 30, the positioning detection element 43 sends a positioning signal. By setting the positioning detection element 43, when the carrier 20 is in the hot pressing position, the positioning detection element 43 sends a positioning signal, at which point the hot pressing mechanism 30 can be controlled to perform hot pressing. This enables automatic control of the hot pressing equipment 100, preventing the hot pressing mechanism 30 from operating when the carrier 20 is not in position, thus improving the automation level and safety of the hot pressing equipment 100.

[0049] Specifically, in this embodiment, the arrival detection element 43 is a mechanical limit switch, which triggers the signal through physical contact. It has a simple structure, low cost, and strong resistance to electromagnetic interference. In other embodiments, the arrival detection element 43 can adopt other structures, such as photoelectric proximity switches, magnetic induction proximity switches, capacitive proximity switches, etc. Non-contact structures result in less mechanical wear and a longer service life. This utility model does not limit the specific type and structure of the arrival detection element 43.

[0050] Please refer to Figure 1 The hot press equipment 100 also includes a cover 11. The cover 11 is used to cover the hot press mechanism 30. The cover 11 is fixedly connected to the equipment body 10. By setting the cover 11, foreign objects are prevented from entering or personnel are accidentally touched during operation, the hot press mechanism 30 is prevented from burning the operator, and the safety of the hot press equipment 100 is improved.

[0051] Specifically, the cover 11 is a transparent cover 11 to facilitate observation of the internal hot-pressing process, thereby allowing operators to operate the equipment or adjust its parameters based on the hot-pressing conditions. In this embodiment, the cover 11 is a transparent acrylic cover 11, allowing clear observation of the equipment's interior without additional lighting. Of course, in other embodiments, the cover 11 can also be a glass cover 11 or made of other materials; this invention does not limit the specific material of the cover 11.

[0052] The beneficial effects of the hot pressing device 100 provided in this embodiment of the present invention include: The hot pressing equipment 100 provided by this utility model includes an equipment body 10, a carrier 20, and a hot pressing mechanism 30. The carrier 20 is disposed on the equipment body 10 and is used to place the battery cell. The hot pressing mechanism 30 includes a first driving member 31 and a hot pressing block 33. The first driving member 31 is disposed on the equipment body 10. The first driving member 31 and the hot pressing block 33 are connected by a drive mechanism and are used to drive the hot pressing block 33 to rise and fall to hot press the insulating part of the battery cell. The hot pressing block 33 is provided with a clearance member for avoiding the battery cell electrode post. By providing a clearance member on the hot pressing block 33, the hot pressing block 33 can avoid the battery cell electrode post, thereby making the hot pressing block 33 completely fit with the top cover of the battery cell, avoiding warping of the film at the battery cell electrode post position, preventing the formation of air bubbles, and achieving complete fit between the hot pressing block 33 and the battery cell electrode post, improving the bonding quality of the battery cell top cover film, and improving product quality.

[0053] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
