Abstract
Description
Technical Field
[0001] The present disclosure relates to manufacturing, and more particularly to an apparatus for facilitating the manual wrapping of modules. Background Art
[0002] In the manufacturing field, particularly in the production of small modules such as parts of battery cells, the process of wrapping or coating these modules is a critical step. This process typically involves applying an adhesive coating to all four sides of the module. This process is performed manually, which can lead to a number of problems. Manually applying the coating can be time-consuming and inefficient, and it also leaves room for errors, resulting in quality issues. Additionally, since all four sides of the module need to be coated, it is not possible to fix or clamp all four sides at once, which further complicates the process. Similarly, it is not feasible to clamp or apply pressure to the sides and bottom of the lugs. These challenges highlight the need to improve the process of wrapping or coating small modules.

[0041] Battery cells are typically stacked to form modules, and these modules can be wrapped with tape. As Figures 1 to 4 shown, the prior art for wrapping a tape around a module includes manually applying the tape. A strip of tape is pulled from a roll, and one side of the module is placed on the tape strip (as shown in the first step of Figure 1 ). Then the module is manually rotated from one side to the next until one cycle of adhesive wrapping is completed (steps 2 to 4 in Figure 1 , also see Figures 2A to 2D ). To add more layers, another tape strip is pulled out (step 5) and the process is repeated until the desired number of tape layers is applied to the module.
[0042] Using this technique, after multiple wrappings, the position of the tape relative to the module is prone to deviation or misalignment. As can be seen from Figures 3A to 3B , initially, the normal wrapped module and the tape are in parallel ([[]] Figure 3A [[]]), but after applying multiple layers by manual wrapping, the position of the module may become non - parallel to the tape ([[]] Figure 3B [[]]). Figure 3A ), but after applying multiple layers by manual wrapping, the position of the module may become non - parallel to the tape ([[]] Figure 3B [[]]). Figure 3B )
[0043] In addition, after multiple flips and multi - layer wrappings, it may be difficult to remember the number of layers that have been applied, which may result in an insufficient or excessive number of layers being applied, and it is difficult to visually inspect the number of layers. If the number of layers is incorrect, all the tape needs to be removed and the module must be rewrapped. Moreover, using this technique, it is difficult to ensure the consistency of the tightness of each layer of wrapping. Quality problems that are difficult to correct may occur (as shown in Figure 4 ), and it is important that no tape is applied on the tab side and the bottom side of the module.
[0044] The device of the present disclosure facilitates the manual wrapping of tape around the module. Using this device, the wrapping efficiency of the module can be improved while eliminating potential errors and quality issues that may occur during manual operation. Since adhesive wrapping is applied to all four sides of the module, it is impossible to fix or clamp all four sides. At the same time, during the wrapping process, the tab side and the bottom side cannot be clamped or subjected to force.
[0045] In one embodiment, as Figure 5 shown, the device includes four quick clamping mechanisms, each of which extends away from the central placement area in a different direction, and all the quick clamping mechanisms can be opened individually, and each quick clamping mechanism extends away from the central placement area in a different direction, as Figures 6A to 6D shown. The clamping mechanism is configured to move the corresponding support member from the open position to the closed position, wherein the closed position supports the module on the carrier table (or central placement area) of the device.
[0046] As Figure 7 shown, the module with tape applied is placed on the carrier table. The clamp is opened on the first side (such as the side facing the operator), and at this time, the other three mechanisms are in the closed position. An adhesive coating ( Figure 8 ) is applied to the first side of the module, and the clamp is closed on the first side, then the clamp is opened on the next adjacent side, and an adhesive coating ( Figure 9 ) is applied to the second side of the module.
[0047] This process continues on the third side ( Figure 10 ) and the last side ( Figure 11 ), resulting in a complete first layer of adhesive being wrapped around the module. This process can be repeated multiple times as needed to apply the desired number of layers, and any excess tape can be cut off at this time.
[0048] In a preferred embodiment, in order to open the clamping mechanism and expose one side of the module to apply the tape, the quick clamping rod moves to the pre-open position, and then the clamping mechanism (with the support member) can slide backward to fully open the mechanism ( Figures 12A to 12C ). In order to close the clamping mechanism, the clamping mechanism is moved inward to the closed position, and then the quick clamping rod is closed ( Figures 13A to 13C ).
[0049] Advantages of using the quick clamp: simple operation, strong clamping force, fast opening and closing process, and convenient use. The operator can easily open and clamp again through the handle.
[0050] The sliding opening distance of the quick clamping mechanism can be adjusted by adjusting the screw and nut or the like, as Figures 14A to 14B shown.
[0051] In addition, the clamping mechanism may have pins inserted in both the open position ( Figures 15A to 15B ) and the closed position ( Figures 16A to 16B ) to ensure that the mechanism does not move during the wrapping process. A bracket with an adjustable position for the safety pin includes a slot ( Figure 17 ) for receiving the pin.
[0052] A guide rail and a slider ( Figure 18 ) may be included on the device to facilitate the sliding of the clamping mechanism, which allows for high positioning accuracy, low wear, and smooth and vibration-free movement. In addition, blocks may be included on both sides of the guide rail to limit the movement of the clamping mechanism so that the clamping mechanism does not slide out of the guide rail.
[0053] Preferably, all components of the quick clamping mechanism and the sliding mechanism will be located below the level of the carrier table of the receiving module (as Figure 19 shown), so that these components do not interfere with the movement of the tape during the wrapping of the module.
[0054] In addition, during the wrapping process, the lower edge of the tape may be adhered to or supported by the surface of the carrier table to help avoid deviation from the proper placement of the tape on the module ( Figures 20 to 21 ).
[0055] The area of the carrier table is preferably larger than the area of the module to be received (as Figure 22 shown), and the fixed pressure plate is designed as a groove structure to ensure that the battery module can be safely and effectively positioned on the carrier table (see Figures 23 to 24 ).
[0056] The device improves production efficiency, reduces the inconvenience of multiple manual flipping steps, and also improves the quality stability and reliability of tape wrapping.
