Description

Technical Field

[0001] This utility model relates to the field of battery cover assembly production technology, specifically to an automatic heat sealing device for battery cover assemblies. Background Technology

[0002] Battery cover assemblies typically consist of end caps, separators, and terminals. The terminals are welded to the cell tabs to ensure the normal flow of charging and discharging current. The end caps are laser-welded to the battery casing to enclose and fix the bare cells and achieve a sealing effect, ensuring a stable internal environment for the battery. Therefore, the cover assembly plays a crucial role in battery applications.

[0003] In existing technologies, battery cover assemblies are mostly sealed and fixed by riveting or using insulating sealant layers. That is, the terminals are fixed to the end cover by riveting or using insulating sealant layers. Since the battery cover assembly needs to have strong temperature resistance in the operating environment, hot pressing is mostly used when using insulating sealant layers to encapsulate the battery cover assembly. The hot pressing device heats both ends of the cover assembly simultaneously, allowing the insulating sealant layer to perform its function and effectively and stably seal and fix the end cover, terminals, and separators.

[0004] Traditional hot pressing devices require manual stacking of components such as end caps, insulating sheets, poles, and insulating sealant layers in a specific order within a fixture for hot pressing. After hot pressing, these components are then removed. This manual operation is not only costly but also has very low hot pressing efficiency and poses significant operational risks.

[0005] Therefore, there is an urgent need for an automatic heat-sealing device for battery cover assemblies to solve the above problems. Utility Model Content

[0006] Based on the above, the purpose of this utility model is to provide an automatic heat sealing device for battery cover assembly, so as to solve the problem of low heat sealing efficiency of existing heat sealing devices.

A drive motor is installed below the conveyor belt, and a drive wheel is installed at the end of the output shaft of the drive motor. At least two rollers are connected around the bottom of the conveyor belt, and a driven wheel is installed at the end of one of the rollers. A synchronous belt connects the drive wheel and the driven wheel.

[0018] As an optional technical solution for an automatic heat sealing device for battery cover assembly, a rotating component is installed between the end cover feeding mechanism and the transfer conveyor line.

The first conveying component individually transports the end caps from the tray to a first heating platform for heating. A sealing ring feeding mechanism then separates the sealing ring from the bottom film, allowing the first conveying component to transport the sealing ring to the first heating platform for heat fusion sealing with the end cap.

[0049] like Figure 1-9 As shown, this utility model provides an automatic heat-sealing device for battery cover assembly. The automatic heat-sealing device for battery cover assembly includes a worktable 1, on which a first X-axis linear module 2 and a second X-axis linear module 3 are mounted. A sealing ring feeding mechanism 4 and an end cap feeding mechanism 5 are installed on one side of the worktable 1 located at the first X-axis linear module 2. A first heating platform 6 is provided between the sealing ring feeding mechanism 4 and the end cap feeding mechanism 5. A first conveying component 20 for transporting sealing rings and end caps is installed on the moving end of the first X-axis linear module 2. A second heating platform 61 and an electrode post feeding mechanism 7 are installed on one side of the worktable 1 located at the second X-axis linear module 3. A transfer conveyor line 8 is provided between the two sides of the first heating platform 6 and the second heating platform 61. A second conveying component 30 is installed on the moving end of the second X-axis linear module 3. The transfer conveyor line 8 is used to transfer the semi-finished products on the first heating platform 6 to one side of the second heating platform 61. The second conveying component 30 has the same structure as the first conveying component 20.

[0050] This utility model provides an automatic heat-sealing device for battery cover assemblies. A tray containing a number of end caps is placed on an end cap feeding mechanism 5, which transports them below a first conveying assembly 20. The first conveying assembly 20 individually transports the end caps from the tray to a first heating platform 6 for heating. A sealing ring feeding mechanism 4 separates the sealing ring from the base film, allowing the first conveying assembly 20 to transport the sealing ring to the first heating platform 6 for heat-sealing with the end cap. After the sealing ring and end cap are heat-sealed, the first conveying assembly 20 transports the semi-finished product to a transfer conveyor line 8. The semi-finished product is transported to one side of the second heating platform 61 via the transfer conveyor line 8. The second handling component 30 then transports the semi-finished product from the transfer conveyor line 8 to the second heating platform 61 for heating. At this time, the second handling component 30 then transports the electrode post in the electrode post feeding mechanism 7 to the second heating platform 61 and performs a heat-melt sealing connection with the semi-finished product. After the heat-melt sealing connection between the electrode post, sealing ring and end cap is completed, it is removed by an external robotic arm. This automatic heat-sealing device for battery cover plate assembly does not require manual operation during the operation. The fully automated operation improves production efficiency and reduces the traditional manual production cost.

[0051] In this embodiment, as Figure 1 and Figure 4 As shown, the first conveying assembly 20 includes a Y-axis linear motor 21 mounted on the moving end of the first X-axis linear module 2. A drive plate 22 is mounted on the moving end of the Y-axis linear motor 21. A ZR-axis motor 23 is mounted on one side of the drive plate 22. A suction nozzle 27 is connected to the output end of the ZR-axis motor 23. The ZR-axis motor 23 drives the suction nozzle 27 to move up and down and rotate, thus picking up the sealing rings from the sealing ring feeding mechanism 4 and placing them onto the end cap on the first heating platform 6 for heat fusion. Simultaneously, after the sealing rings and end caps have completed heat fusion, the ZR-axis motor continues to convey the sealing rings onto the end cap. The suction nozzle 27 on the Z-axis motor 23 picks up and transfers the semi-finished product. A Z-axis moving module 24 is mounted on the other side of the drive plate 22. The Z-axis moving module 24 includes a Z-axis motor 25 mounted on top of the drive plate 22. A drive wheel is mounted on the output shaft of the Z-axis motor 25, and a driven wheel is mounted on the drive plate 22 below the drive wheel. A synchronous belt connects the drive wheel and the driven wheel. A slide rail is provided on the drive plate 22, and an "L"-shaped bracket 26 slides on the slide rail. One side of the "L"-shaped bracket 26 is fixedly connected to the synchronous belt, and a suction nozzle 27 is mounted on the bottom of the "L"-shaped bracket 26. The Z-axis motor 25 drives the drive wheel, which in turn drives the synchronous belt, causing the "L"-shaped bracket 26 and the suction nozzle 27 connected to the bottom of the "L"-shaped bracket 26 to move up and down, facilitating the handling of the pole piece.

[0052] Specifically, in this embodiment, the first transport assembly 20 and the second transport group have the same structure. A first upper camera 28 is mounted on the drive plate 22, and lower cameras 60 are respectively mounted on one side of the first heating platform 6 and the second heating platform 61. In the first transport assembly 20, the cooperation between the first upper camera 28 and the lower camera 60 on one side of the first heating platform 6 allows the end cap picked up by the suction nozzle 27 of the "L"-shaped bracket 26 to be transported to the first heating platform 6, recording its posture and coordinates. This enables the sealing ring picked up by the suction nozzle 27 on the ZR axis motor 23 to be able to... Precise alignment and heat fusion with the end cap increases the accuracy of the heat sealing assembly between the sealing ring and the end cap. In the second transport assembly 30, the cooperation between the first upper camera 28 and the lower camera 60 on one side of the second heating platform 61 allows the attitude and coordinates of the electrode column picked up by the suction nozzle 27 of the "L"-shaped bracket 26 to be recorded when it is transported to the second heating platform 61. This enables the semi-finished products picked up by the suction nozzle 27 on the ZR axis motor 23 and the transfer conveyor line 8 to be precisely aligned and heat-fused with the electrode column, increasing the accuracy of the heat-fused sealing assembly of the battery cover assembly.

[0053] Furthermore, such as Figure 8 and Figure 9 As shown, the transfer conveyor line 8 includes a Y-axis linear module 80 mounted on the workbench 1 and a transfer bracket 81 mounted on the moving end of the Y-axis linear module 80. The transfer bracket 81 is provided with positioning holes 82 for receiving semi-finished products that have been heat-melted on the first heating table 6. A rotating assembly 9 is installed between the end cap feeding mechanism 5 and the transfer conveyor line 8. The rotating assembly 9 includes a rotary motor 90 mounted on the workbench 1 and a rotating seat 91 mounted on the output shaft of the rotary motor 90. The rotating seat 91 is provided with a limiting hole 92, which is connected to an external negative pressure system. In this structure, after the end cap and sealing ring on the first heating table 6 have completed the heat-melted sealing connection, the ZR axis motor 23 on the first conveying assembly 20 drives the suction nozzle 27 to deliver the semi-finished product. The finished product is sucked up and transported into the limiting hole 92 of the rotating seat 91. Under the action of the external negative pressure system, the semi-finished product is firmly adsorbed into the limiting hole 92. The rotating motor 90 rotates 180 degrees, causing the semi-finished product to flip over. The negative pressure airflow is interrupted, and the semi-finished product is placed into the positioning hole 82 on the transfer bracket 81. At this time, the sealing ring in the semi-finished product is at the bottom, while the end cap is above the sealing ring, so that the ZR axis motor 23 on the second conveying component 30 can drive its suction nozzle 27 to adsorb the semi-finished product and perform heat fusion sealing with the pole on the second heating table 61 (that is, in this posture, the sealing ring is located between the end cap and the pole, and the end cap and the pole are heat fused and sealed by the upper and lower surfaces of the sealing ring).

[0054] In this embodiment, as Figure 5As shown, the sealing ring feeding mechanism 4 includes a sealing ring separation component 40 and a longitudinal base plate 41 installed on one side of the sealing ring separation component 40. The longitudinal base plate 41 is equipped with a turntable 42 and multiple staggered rollers 43. Before the sealing ring is separated, there is a protective film on one side of its bottom. Therefore, after the sealing ring is produced, it is collected in rolls by the protective film. In this structure, the rolled sealing ring is installed on the turntable 42 for stretching and conveying, while the multiple staggered rollers 43 will unwind the stretched sealing ring, which facilitates the separation of the sealing ring and the protective film by the sealing ring separation component 40. After separation, the sealing ring will stay on the sealing ring separation component 40 and wait for the first conveying component 20 to convey it, which improves the separation and conveying efficiency of the sealing ring.

[0055] In this embodiment, as Figure 6 As shown, the end cap feeding mechanism 5 includes a frame 50 and a conveyor belt 51 mounted on the frame 50. A drive motor 52 is mounted below the conveyor belt 51, and a drive wheel is mounted at the end of the output shaft of the drive motor 52. At least two rollers 43 are connected around the bottom of the conveyor belt 51. In this embodiment, three rollers 43 are preferred. A driven wheel is mounted at the end of the middle roller 43. A synchronous belt connects the drive wheel and the driven wheel. The rotation of the drive motor 52 drives the drive wheel to rotate, thereby driving the conveyor belt to run. In this structure, the material tray carrying the end caps only needs to be placed on the conveyor belt manually or by an external robot. The conveyor belt transports the material to the bottom of the first handling component 20 for end cap handling and feeding, which increases the feeding efficiency of the end caps.

[0056] In this embodiment, as Figure 2 and Figure 3 The pole column feeding mechanism 7 is a flexible vibrating feeding plate. A second upper camera 70 is mounted above the flexible vibrating feeding plate. A pole column picking component 71 is installed at the other end of the second X-axis linear module 3 away from the second conveying component 30. The pole column picking component 71 is a structure of ZR axis motor 23 and suction nozzle 27 connected to its output end. A transfer table 72 is installed on one side of the flexible vibrating feeding plate. In this structure, the pole pieces in the material tray are dispersed by a flexible vibrating feeding tray, and then captured by a second upper camera 70. The pole piece picking component 71 then transports the pole piece in the target posture to the transfer platform 72. The Z-axis moving module 24 on the second transport component 30 drives the suction nozzle 27 to transport the pole piece on the transfer platform 72 to the second heating platform 61. After this process is completed, the ZR axis motor 23 on the second transport component 30 drives the suction nozzle 27 to transport the semi-finished product on the transfer bracket 81 to the second heating platform 61 for precise hot-melt sealing with the pole piece. After the end cap, sealing ring and pole piece are sealed, they are transported to the outside for collection by an external robot or by a conveyor line set on the worktable 1.

[0057] Furthermore, such as Figure 7 As shown, to enable the second heating platform 61 to more stably support the electrode post, a clearance hole 611 is provided on the second heating platform 61. The clearance hole 611 provides support space for the protruding part of the electrode post, allowing the electrode post to be placed stably on the second heating platform 61 for sealing, thus improving the sealing effect of the battery cover assembly. At the same time, multiple heat insulation pillars 610 are connected to the bottom of the first heating platform 6 and the second heating platform 61 respectively to prevent the heat from the heating platform from being conducted to other components. This improves the heating effect of the heating platform and increases the service life of the automatic heat sealing device for the battery cover assembly.

[0058] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
