Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a heating film pressurization device for power battery modules. Background Technology

[0002] In the production process of power battery modules, the bonding quality of the heating film directly affects the temperature control performance and safety of the module. Existing heating film pressurization equipment mostly adopts unidirectional or bidirectional pressurization methods, which have problems such as a single pressurization direction and uneven bonding. This can easily lead to local wrinkles, bubbles, or excessive bonding gaps in the heating film, affecting heat transfer efficiency.

[0003] Meanwhile, the traditional equipment suffers from insufficient smoothness in the connection between conveying and pressurizing actions. During pressurization, the conveying mechanism can easily interfere with the pressurizing process, requiring manual adjustment of the module position. This not only reduces production efficiency but may also affect pressurization accuracy due to human error. Furthermore, the pressurizing components of existing equipment have poor versatility for different specifications of power battery modules, and the replacement and adjustment procedures are cumbersome, making it difficult to meet diverse production needs.

[0004] To address the aforementioned issues, this invention designs a heating film pressurizing device that features multi-directional synchronous pressurization, coordinated conveying and pressurization actions, and replaceable pressurizing components. This device aims to improve pressurization quality and production efficiency, and adapt to the pressurization requirements of modules of different specifications. Utility Model Content

[0005] This utility model aims to provide a heating film pressurization device for power battery modules, which solves the problems of single pressurization direction, interference between conveying and pressurization actions, and poor versatility of pressurization components in existing equipment, and realizes the functions of multi-directional synchronous pressurization, coordinated action, and flexible adaptation to different module specifications.

[0006] The heating film pressurization device for power battery modules provided in this application adopts the following technical solution: A heating film pressurizing device for a power battery module includes a base, the base including a base plate with a through cavity; the vertically corresponding area of ​​the through cavity is set as a pressurizing work station; a carrying and conveying mechanism mounted above the base for conveying the battery module to the pressurizing work station; the pressurizing component includes pressurizing units in at least three directions, respectively corresponding to the bottom, side and top of the battery module; each pressurizing unit includes a driving component and a pressurizing actuator, the driving component driving the pressurizing actuator to achieve multi-directional synchronous pressurization of the power battery module.

[0007] Preferably, the pressure application assembly includes at least: a bottom pressure mechanism, a side pressure mechanism, and a top pressure mechanism; The bottom pressurization mechanism includes: a U-shaped frame fixed to the equipment base and opposite to the pressurization work station; a telescopic component A and a pressurization plate A are installed on the side of the U-shaped frame near the equipment base; the pressurization plate A is connected to the output end of the telescopic component A, and the pressurization plate A is driven to move towards the battery module through the telescopic component A; The side pressurization mechanism includes: displacement support frames located on both sides above the equipment base and slidably connected to the equipment base; a telescopic component B and a pressure plate B are installed on one end of the displacement support frame near the battery module.

[0008] The top pressurization mechanism includes: a top frame disposed above the pressurization work station, and a telescopic component C and a pressurization plate C installed below the top frame.

[0009] Preferably, the pressure plate C can be replaced with a replacement pressure cover, which is configured as a cover structure and can cover all outer surfaces of the battery module except the bottom surface.

[0010] Preferably, the replacement pressure cover includes: a pressure cover body having an open end and adapted to the external dimensions of the battery module; and multiple end face pressure plates D respectively installed inside the pressure cover body.

[0011] Preferably, the carrying and conveying mechanism includes: a fixed conveying frame fixed to the equipment base and located on both sides of the battery module; an adjustable conveying frame set on both sides of the pressurization work station; and a plurality of conveying rollers arranged at equal distances along the conveying roller shaft and the adjustable conveying frame. The rotation of the conveying roller shaft drives the battery module to move from one end of the equipment base to the other end.

[0012] Preferably, the fixed conveyor frame and the adjustable conveyor frame on both sides cooperate with the conveyor roller to mount the battery module. The adjustable conveyor frame is slidably connected to the base plate. When the battery module moves to the position of the adjustable conveyor frame, the position of the adjustable conveyor frame is adjusted to adjust the mounting state of the battery module.

[0013] In summary, this application includes the following beneficial technical effects: By coordinating the pressure mechanisms at the bottom, sides, and top, multi-directional synchronous pressure is applied to the power battery module, avoiding uneven bonding caused by traditional unidirectional pressure, effectively reducing defects such as wrinkles and bubbles in the heating film, and improving the tightness of the bonding between the heating film and the module body.

[0014] The adjustable conveyor frame features a sliding avoidance design, ensuring that the conveying mechanism and the pressurizing mechanism do not interfere with each other. This eliminates the need for manual adjustment of module positions, achieving automated connection between conveying, positioning, and pressurizing, reducing operational steps, and improving production efficiency.

[0015] The pressure plate C of the top pressure mechanism can be replaced with a replacement pressure cover, which can meet the needs of conventional multi-directional pressure and achieve all-round pressure. At the same time, the shape of the replacement pressure cover can be adjusted according to different specification modules, improving the versatility of the equipment and adapting to diverse production scenarios.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses a heating film pressurization device for a power battery module. (Refer to...) Figure 1 The system includes: a base 1, a conveying mechanism 2, a battery module 3, and a pressurizing assembly. The base includes a base plate 11 with a through cavity 12 and a sliding groove 13. The vertical area corresponding to the through cavity 12 is set as a pressurizing station. The pressurizing station is the core area for pressurizing the heating film of the power battery module. The through cavity 12 provides space for the movement of the bottom pressurizing mechanism, ensuring that the bottom pressurizing action can be successfully achieved. The conveying mechanism 2 is mounted on the base 1 and accurately transports the power battery module 3 to be pressurized to the pressurizing station. After pressurization, it transports the module to the next process. The pressurizing assembly includes pressurizing units in at least three directions, corresponding to the bottom, side, and top of the power battery module 3, respectively. Each pressurizing unit includes a driving component and a pressurizing actuator. The driving component can drive the pressurizing actuator to move towards the module, thereby achieving multi-directional synchronous pressurization of the power battery module 3.

[0022] like Figure 1 As shown, the carrying and conveying mechanism 2 includes: a fixed conveying frame 21, an adjustable conveying frame 22, and conveying rollers 23; the fixed conveying frame 21 is fixedly connected to the equipment base 1 and symmetrically distributed on both sides of the power battery module 3, providing stable side support for module conveying; the adjustable conveying frame 22 is set on both sides of the pressurization work station and is slidably connected to the base plate 11, and its position can be adjusted along the horizontal direction of the base plate 11; several conveying rollers 23 are arranged at equal distances along the length direction of the fixed conveying frame 21 and the adjustable conveying frame 22, and the conveying rollers 23 drive the power battery module 3 to move from one end of the equipment base 1 to the other end by rotating, realizing the automated conveying of the module.

[0023] In actual use, the fixed conveyor frame 21 and the adjustable conveyor frame 22 on both sides work together with the conveyor roller 23 to mount the power battery module 3. When the module moves to the position corresponding to the adjustable conveyor frame 22, the position of the adjustable conveyor frame 22 can be adjusted to change the support state of the conveyor roller 23 on the module, thereby adjusting the mounting state of the module and avoiding interference for subsequent pressurization.

[0024] like Figure 1 As shown, the pressure application components include: a bottom pressure mechanism 4, a side pressure mechanism 5, and a top pressure mechanism 6; the bottom pressure mechanism 4 is fixedly connected to the equipment base 1 and its position corresponds to the pressure operation station. Its structure includes a U-shaped frame 41, a telescopic component A42, and a pressure plate A43; the U-shaped frame 41 provides an installation base for the bottom pressure mechanism 4, its opening faces the pressure operation station, and a space for the installation of the telescopic component A42 is reserved on the side near the equipment base 1; the telescopic component A42 is installed on the side of the U-shaped frame 41 near the equipment base 1, and the pressure plate A43 is fixedly connected to the output end of the telescopic component A42; when bottom pressure is required, the telescopic component A42 drives the pressure plate A43 to move towards the bottom of the power battery module 3, thereby achieving load-bearing and pressure on the bottom of the module and ensuring the tightness of the heating film at the bottom of the module.

[0025] like Figure 2 As shown, the side pressurization mechanism 5 is located on both sides above the equipment base 1. Its structure includes a displacement support frame 51, a telescopic component B52, and a pressure plate B53. The displacement support frame 51 is slidably connected to the equipment base 1 and can be adjusted in position along the horizontal direction of the equipment base 1 to adapt to power battery modules 3 of different widths. The telescopic component B52 is installed at one end of the displacement support frame 51 near the power battery module 3, and the pressure plate B53 is connected to the output end of the telescopic component B52. During pressurization, the telescopic component B52 drives the pressure plate B53 to move towards the side of the module, which not only achieves side positioning of the module but also completes the pressurization operation of the side heating film, preventing the module from shifting during the pressurization process.

[0026] like Figure 2As shown, the top pressurization mechanism 6 is located directly above the pressurization work station. Its structure includes a top frame 61, a telescopic component C62, and a pressurization plate C63. The top frame 61 is fixed relative to the equipment base 1, providing installation support for the telescopic component C62, and its position corresponds precisely to the pressurization work station. The telescopic component C62 is installed below the top frame 61, and the pressurization plate C63 is connected to the output end of the telescopic component C62. When pressurizing from the top, the telescopic component C62 drives the pressurization plate C63 to move towards the top of the power battery module 3, cooperating with the bottom and side pressurization mechanisms 5 to achieve multi-directional synchronous pressurization.

[0027] In addition, to meet the comprehensive pressurization requirements, such as Figure 3 As shown, the pressure plate C63 can be replaced by a replacement pressure cover 7. The replacement pressure cover 7 is a cover structure, specifically including a pressure cover body 71 and a pressure plate D72; the pressure cover body 71 has an open end, and its overall dimensions are adapted to the power battery module 3, so it can be placed on the outside of the module; multiple pressure plates D72 are provided, which are respectively installed on multiple end faces (front, rear, left, right and top end faces) inside the pressure cover body 71; when the replacement pressure cover 7 is used, it can cover all the outer surfaces of the power battery module 3 except for the bottom surface, and the heating film bonding operation of the module can be realized through the synchronous pressure of multiple pressure plates D72.

[0028] In actual use, the carrying conveyor mechanism 2 is started first, and the conveyor roller 23 rotates to drive the power battery module 3 to be pressurized to move along the fixed conveyor frame 21 and the adjustable conveyor frame 22 to the pressurization work station. When the module moves to the vertical corresponding area of ​​the through cavity 12 (pressurization work station), the carrying conveyor mechanism 2 stops conveying and completes the positioning of the module; the displacement carrier frame 51 of the side pressurization mechanism 5 is adjusted to a position that matches the width of the module, and the telescopic component B52 drives the pressurization plate B53 to move to the side of the module to achieve side positioning of the module; at the same time, the adjustable conveyor frame 22 slides outward along the equipment base 1, driving the conveyor roller 23 to move outward, canceling the mounting and positioning of the bottom of the module, and making room for the movement of the bottom pressurization mechanism 4. The telescopic component 42A of the bottom pressurizing mechanism 4 drives the pressurizing plate 43A to move upward, contact the bottom of the module and apply pressure, so as to realize bottom bearing and pressurization; the telescopic component C62 of the top pressurizing mechanism 6 drives the pressurizing plate C63 to move downward, and applies pressure to the top of the module; the telescopic component B52 of the side pressurizing mechanism 5 continues to drive the pressurizing plate B53, and applies pressure to the side of the module. The three work together to complete multi-directional synchronous pressurization.

[0029] If full-range pressure is required, the pressure plate C63 of the top pressure mechanism 6 is removed and replaced with a replacement pressure cover 7. The replacement pressure cover 7 is installed outside the module through an open end cover, and its multiple pressure plates D72 contact the front, back, left, right and top end faces of the module respectively. Full-range pressure is achieved by synchronous pressure application of each pressure plate D72.

[0030] After pressurization is completed, the telescopic component 42A of the bottom pressurization mechanism 4 drives the pressurization plate 43A to reset downwards; the side pressurization mechanism 5 maintains the positioning of the module to prevent the module from shifting; the adjustable conveyor frame 22 slides inwards along the equipment base 1, driving the conveyor roller shaft 23 to reset and re-mount the bottom of the module; finally, the conveyor roller shaft 23 of the carrying conveyor mechanism 2 rotates to transport the pressurized module to the next process, and at the same time transports the new module to be pressurized to the pressurization work station to enter the next work cycle.

[0031] In the above embodiment, the carrying conveying mechanism 2 is started, and the stepper motor (model: Xinje 86HS20) drives the conveying roller shaft 23 to move; the telescopic component C62B52A42 is selected from cylinders, electric push rods or hydraulic cylinders, electric push rod (model: Topstar TS-P80-100); hydraulic cylinder model: SMC CQ2A63-50DZ; the displacement bearing frame 51 is slidably connected to the equipment base 1 through linear guide rail (model: THK SR20W) and is set in the slide groove 13; each pressure plate D72 has a small cylinder (model: Airtac SC32-30, rated thrust 300N) bolted to its back and embedded in the mounting groove of the corresponding end face inside the pressure cover 71; when the replacement pressure cover 7 is used, it can cover all the outer surfaces of the power battery module 3 except the bottom surface, and the corresponding pressure plate D72 is synchronously pressured by driving the five small cylinders.
