[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0044] Example 1:

[0045] Please see the appendix Figure 1-4 This utility model provides a heating film pressing device 100, which realizes automatic pressing of the heating film and the battery module 7 through an online process, and also has a visual inspection function during the pressing process. In addition, the heating film pressing device 100 also has high adaptability.

[0046] like Figure 1 As shown, the heating film pressing equipment 100 includes a battery module conveying mechanism 1 and a pressing mechanism 2. The battery module conveying mechanism 1 can be connected to upstream or downstream process equipment and is used to convey battery modules 7, thereby ensuring the continuity of the battery module 7 production process, guaranteeing that the battery module 7 is always on the production line, and improving production efficiency. The battery module conveying mechanism 1 is provided with a pressing position 11. When the battery module 7 reaches the pressing position 11, the pressing mechanism 2 presses the battery module 7.

[0047] The pressurizing mechanism 2 is located above the pressurizing position 11. Specifically, as follows... Figure 2 As shown, the pressurizing mechanism 2 includes a vertical motion module 21, a pressurizing component 22, and a vision detection component 23. The pressurizing component 22 and the vision detection component 23 are connected to the vertical motion module 21 and are located on the periphery of the pressurizing position 11 to facilitate operation on the battery module 7 located at the pressurizing position 11. Under the action of the vertical motion module 21, the pressurizing component 22 and the vision detection component 23 can move vertically, from their initial state to a position aligned with the side of the battery module 7. The pressurizing component 22 is symmetrically arranged on the same horizontal plane and is located on both sides of the pressurizing position 11 to clamp the battery module 7.

[0048] The vision inspection component 23 can be disposed relative to the top surface or at least one of the four sides of the battery module 7, and is used to perform quality inspection on the surface of the battery module 7. For example, the vision inspection component 23 performs image scanning on the surface of the battery module 7, and determines whether the screws on the surface of the battery module 7 are installed in place and whether there are any problems such as deformation or damage based on the obtained image information, thereby inspecting the quality of the battery module 7.

[0049] When the heating film pressing equipment 100 is operating, the battery module conveying mechanism 1 transports the battery module 7. When the battery module 7 reaches the pressing position 11, the vertical motion module 21 drives the pressing component 22 and the vision inspection component 23 to move downwards until the pressing component 22 is aligned with the side of the heating film to be pressed, and the vision inspection component 23 reaches the appropriate inspection position. At this time, the pressing components 22 located on both sides of the battery module 7 move towards each other to clamp and press the side of the battery module 7 to ensure that the heating film is pressed onto the surface of the battery module 7. At the same time, the vision inspection component 23 scans the surface of the battery module 7 for quality inspection.

[0050] The vertical motion module 21 assembly gives the heating film pressing equipment 100 high adaptability. Specifically, the pressure application component 22 and the vision inspection component 23 can move vertically under the action of the vertical motion module 21 to adapt to heating films and battery modules 7 at different heights. Meanwhile, since the pressure application component 22 and the vision inspection component 23 are located above the pressure application position 11, the distribution direction of the pressure application component 22 can be the same as or perpendicular to the transmission direction of the battery module transmission mechanism 1, meaning it is not limited by the battery module transmission mechanism 1 and can press different sides of the battery module 7, improving the versatility of the heating film pressing equipment 100.

[0051] like Figure 1 As shown, the X-axis is the transport direction of the battery module conveying mechanism 1, the Y-axis is on the same horizontal plane as the X-axis and perpendicular to the X-axis, the Y-axis is the direction of the width of the battery module conveying mechanism 1, and the Z-axis is perpendicular to the plane formed by X and Y.

[0052] In this embodiment, the pressurizing components 22 are distributed facing each other in the Y-axis direction to press and connect the two sides of the battery module 7 in the Y-axis direction. In some embodiments, the pressurizing components 22 may be distributed opposite each other in the X-axis direction, or simultaneously distributed facing each other in both the X and Y axes, thereby pressing different sides of the battery module 7. Similarly, the visual inspection component 23 can also be adjusted in position as needed to meet different quality inspection requirements, thereby making the heating film pressing device 100 highly adaptable.

[0053] In this embodiment, the distribution direction of the visual inspection component 23 is perpendicular to the distribution direction of the pressurizing component 22. The visual inspection component 23 is symmetrically arranged in the X direction, and the pressurizing component 22 is symmetrically arranged in the Y-axis direction, so as to perform operations on different sides of the battery module 7 respectively.

[0054] Furthermore, an integrated plate 24 is connected to the vertical motion module 21, and the vision inspection component 23 and the pressure application component 22 are both connected to the integrated plate 24. The vertical motion module 21 drives the vision inspection component 23 and the pressure application component 22 to move simultaneously through the integrated plate 24, thereby enabling vision inspection while performing heating film pressing, improving the efficiency of the heating film pressing equipment 100.

[0055] like Figure 3 and Figure 4 As shown, in this embodiment, the pressurizing component 22 includes a pressurizing driver 221 and a pressurizing block 222 connected to the output terminal of the pressurizing driver 221. The pressurizing block 222 is closer to the pressurizing position 11 than the pressurizing driver 221. After the pressurizing component 22 is aligned with the side of the battery module 7, the pressurizing driver 221 drives the pressurizing block 222 to extend until the pressurizing block 222 abuts against the side of the battery module 7, thereby achieving the pressing of the heating film with the side of the battery module 7.

[0056] Reference Figures 1 to 4 Below the integrated board 24, there is also a movable guide rail 223, which extends along the Y-axis. The pressure block 222 is movably connected to the movable guide rail 223. Under the action of the pressure driver 221, the pressure block 222 moves along the movable guide rail 223 to move closer to or away from the battery module 7.

[0057] The visual inspection component 23 is fixedly connected to the integrated plate 24. In some embodiments, a lateral motion module or a three-dimensional motion module may also be provided between the visual inspection component 23 and the integrated plate 24, so that the position of the visual inspection component 23 can be adjusted under the action of the motion module, thereby increasing the range of quality inspection.

[0058] To prevent damage to the battery module 7 during the pressing process with the heating film, the pressure block 222 is also connected to an elastic component 224. Specifically, the pressure block 222 has a pressing surface for abutting against the battery module 7, and the elastic component 224 is connected to the side of the pressure block 222 away from the pressing surface. The elastic component 224 provides a cushioning function for the pressure block 222. In this embodiment, the elastic component 224 includes a pressure spring 2241 and a limiting plate 2242. The output end of the pressure driver 221 is provided with a connecting shaft 2243. The pressure spring 2241 is sleeved on the connecting shaft 2243. One end of the pressure spring 2241 is connected to the limiting plate 2242, and the other end is connected to the pressure block 222. When the pressure driver 221 drives the pressure block 222 to abut against the side of the battery module 7, as the pressure increases, the pressure block 222 will be subjected to the reaction force of the pressure and act on the pressure spring 2241. Subsequently, the pressure spring 2241 is compressed to provide a buffer for the pressure block 222 and prevent the pressure block 222 from exerting too much force on the battery module 7.

[0059] In addition, the pressing surface of the pressure block 222 is also provided with a buffer pad 2221, which is made of a soft material such as silicone. The combination of the pressure block 222 and the buffer pad 2221 ensures a tight press between the heating film and the battery module 7, while avoiding damage to the heating film and the battery module 7, thereby improving the quality of the heating film pressing process.

[0060] Specifically, the heating film pressing device 100 also includes a rangefinder 225. In this embodiment, the rangefinder 225 is connected above the pressure block 222. The rangefinder 225 is used to monitor the distance between the pressure block 222 and the battery module 7, so as to provide real-time feedback and control the operation of the pressure driver 221. It can also measure the changes in the battery module 7 before and after pressing with the heating film to determine the pressing effect of the heating film.

[0061] Example 2:

[0062] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the heating film pressing device 100 of this utility model. For similarities, please refer to Embodiment 1; the differences are explained below.

[0063] like Figures 5 to 7 As shown, the heating and pressing equipment also includes a battery module carrier 3, which is movably connected to the battery module conveying mechanism 1 and transported by the mechanism. The battery module carrier 3 includes a base plate 31, on which a first-direction limiting portion 32 and a second-direction limiting portion 33 are provided for positioning the battery module 7. A receiving position for the battery module 7 is formed between the first-direction limiting portion 32 and the second-direction limiting portion 33. At least one of the first-direction limiting portion 32 and the second-direction limiting portion 33 is dimensionally adjustable in its direction. In this embodiment, the first-direction limiting portions 32 are symmetrically distributed along the Y-axis, and each first-direction limiting portion 32 includes a first limiting block 322 for abutting against the battery module 7. One side of the first-direction limiting portion 32 also has an adjusting slide rail 321, and the first limiting block 322 is movably connected to the adjusting slide rail 321. Based on the dimensions of the battery module 7 in the Y-axis direction, the first limiting block 322 is adjusted to limit the battery module 7 together with the first limiting block 322 at the first direction limiting part 32 on the other side.

[0064] Similar to the first direction limiting part 32, the second direction limiting part 33 is provided with a second limiting block 331, and at least one of the second limiting blocks 331 is movably connected to the substrate 31. In this embodiment, the second direction limiting parts 33 are symmetrically distributed along the X-axis, and one of the second limiting blocks 331 is connected to the adjustment driver 332 via a telescopic shaft. The second limiting block 331 is located at the output end of the telescopic shaft, and the second limiting block 331 moves closer to or further away from the battery module 7 under the action of the adjustment driver 332. According to the size of the battery module 7 in the X-axis direction, the second limiting block 331 is movably adjusted to limit the battery module 7 together with the second limiting block 331 of the other side of the second direction limiting part 33.

[0065] Under the action of the first direction limiting part 32 and the second direction limiting part 33, the battery module 7 is fixed on the battery module carrier 3, and the battery module carrier 3 can be adapted to battery modules 7 of different sizes. It is understood that this is not a unique limitation on the specific limiting method of the first direction limiting part 32 and the second direction limiting part 33, and can be adjusted according to needs.

[0066] Specifically, the tops of the first limiting block 322 and the second limiting block 331 should be lower than the bottom of the heating film during pressing, so as to ensure that the heating film and the battery module 7 can be fully pressed together and to ensure the quality of the heating film pressing.

[0067] Furthermore, the heating film pressing equipment 100 also includes a lifting mechanism 4 and a carrier limiting mechanism 5. The battery module conveying mechanism 1 includes a conveying track 12, to which the battery module carrier 3 is movably connected and transported. In the pressurization position 11, the lifting mechanism 4 is located below the battery module carrier 3, and the carrier limiting mechanism 5 is close to the battery module carrier 3. The carrier limiting mechanism 5 can be a latch structure or a baffle structure to prevent movement of the battery module carrier 3.

[0068] When the battery module carrier 3 is transported from the conveyor rail 12 to the pressurization position 11, the carrier limiting mechanism 5 operates, stopping the battery module carrier 3 from moving relative to the conveyor rail 12. Then, the lifting mechanism 4 operates, pushing the battery module carrier 3 along the Z direction, moving it away from the conveyor rail 12. Subsequently, the pressurization mechanism 2 operates on the battery modules 7 on the battery carrier.

[0069] Example 3:

[0070] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the heating film pressing device 100 of this utility model. For similarities, please refer to Embodiment 1; the differences are explained below.

[0071] like Figure 8As shown, the heating film pressing equipment 100 also includes a barcode scanning mechanism 6, which is located near the pressure application position 11 and is used to scan the serial number of the battery module 7. The barcode scanning mechanism 6 can cooperate with the rangefinder 225, the pressure application component 22, and the vision inspection component 23 to upload the parameters and image information obtained during the heating film pressing process to the platform, and correspond one-to-one with the serial number of the battery module 7. This is beneficial for mastering the parameters of the manufacturing process of each battery module 7, so that problems can be traced in a timely manner when they occur, thereby optimizing different processes.

[0072] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
