Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to a U-shaped battery edge-attaching device. Background Technology

[0002] Lithium-ion batteries are rechargeable batteries with wide applications in various new energy industries. U-shaped batteries are also a type of lithium-ion battery, but because their shape differs from that of conventional rectangular batteries, more precise adhesive application is often required when attaching the edges of U-shaped batteries. During the production process of lithium-ion batteries, adhesive is applied to facilitate subsequent processing. When applying adhesive, the contact areas between the tape and the lithium-ion battery include the top, side, and bottom surfaces to achieve proper edge attachment. Currently, most technologies use manual or machine-assisted adhesive application. Existing machine-assisted adhesive application methods are prone to bulging or air bubbles after application, often requiring manual correction and rework. Manual adhesive application is prone to issues such as slanted application and missed areas, and the production cost of manual adhesive application is relatively high. Therefore, improvements are needed. Utility Model Content

The vertical drive slider is drivenly connected to the mounting plate. The adhesive application block is provided on the mounting plate and located on the side away from the vertical drive slider.

[0006] Specifically, the adhesive application mechanism further includes an adhesive cutter and a cutter drive. A cutter groove is provided below the adhesive application block, and the adhesive cutter is located in the cutter groove.

[0020] like Figures 1 to 4 As shown, a U-shaped battery edge-applying device includes a glue feeding mechanism and an glue-applying mechanism. The glue feeding mechanism includes a glue feeding tray 10 and several glue feeding auxiliary rollers 11. The adhesive tape to be applied is wound around the glue feeding tray 10 and extends into the glue-applying mechanism through contact with the glue feeding auxiliary rollers 11. The glue-applying mechanism includes a glue-applying drive and a glue-applying block 26. The glue-applying block 26 is provided with a tape channel, through which the adhesive tape to be applied extends to the front end of the glue-applying block 26. The glue-applying drive is driven by the glue-applying block 26 and drives the glue-applying block 26 to move in the horizontal and vertical directions. When edge-applying a U-shaped battery, the adhesive tape to be applied is transferred to the glue-applying block 26 by the glue feeding tray 10 and the glue feeding auxiliary rollers 11, and then the glue-applying drive drives the glue-applying block 26 to move in the horizontal and vertical directions, so as to achieve rapid edge-applying of the U-shaped battery and thus effectively improve the edge-applying efficiency of the U-shaped battery.

[0021] The adhesive application mechanism includes a mounting frame 20 and a mounting plate 21. The adhesive application drive components include a horizontal drive motor 22 and a horizontal drive slider. The drive end of the horizontal drive motor 22 is provided with a horizontal drive screw, and the horizontal drive slider is sleeved on the horizontal drive screw and driven by the horizontal drive screw. The mounting frame 20 is connected to the horizontal drive slider. A vertical drive motor 23 is provided on the mounting frame 20, and a vertical drive slider is provided on the drive end of the vertical drive motor 23. The vertical drive slider is driven by the mounting plate 21. The adhesive application block 26 is disposed on the mounting plate 21 and located on the side away from the vertical drive slider. In this embodiment, the horizontal drive motor 22 drives the horizontal drive slider to move horizontally, thereby driving the adhesive application block 26 to move horizontally. The vertical drive motor 23 drives the vertical drive slider to move vertically, thereby driving the adhesive application block 26 to move vertically. This achieves multi-dimensional movement of the adhesive application block 26 when applying adhesive to the edge of the U-shaped battery, thereby improving the edge application efficiency.

[0022] The adhesive application mechanism also includes an adhesive cutter 24 and a cutter drive. A cutter groove is provided below the adhesive application block 26, and the adhesive cutter 24 is located in the cutter groove. The cutter drive is driven by the adhesive cutter 24, and drives the adhesive cutter 24 to cut the adhesive tape. The cutter drive includes a cutter drive cylinder 25, which is located on the lower surface of the adhesive application block 26. The piston rod end of the cutter drive cylinder 25 is driven by the adhesive cutter 24. In this embodiment, the cutter drive cylinder 25 drives the adhesive cutter 24 to move, thereby facilitating the extension and retraction of the adhesive cutter 24 for cutting and resetting.

[0023] The mounting plate 21 is equipped with a fine-tuning slide rail 30, a fine-tuning slider 31, and a fine-tuning transmission rod 32 connected to the adhesive block 26. The mounting plate 21 is also equipped with a fine-tuning cylinder 33, which is connected to the fine-tuning slider 31. In this embodiment, the fine-tuning cylinder 33 drives the fine-tuning transmission rod 32, which in turn moves the adhesive block 26 on the fine-tuning slide rail 30, facilitating fine-tuning of the adhesive block 26 and improving the accuracy of the U-shaped battery's edge application.

[0024] A glue-fixing block 40 is provided on the mounting plate 21. The glue-fixing block 40 has a glue-passing hole 41. The tape extends to the tape channel by passing through the glue-passing hole 41. A glue-fixing cylinder 42 and a glue-fixing pressure block 43 are provided in the glue-passing hole 41. The piston rod end of the glue-fixing cylinder 42 is connected to the glue-fixing pressure block 43 and drives the glue-fixing pressure block 43 to move in the vertical direction, thereby opening or closing the glue-passing hole 41. In this embodiment, a glue-fixing block 40 is provided on the mounting plate 21. By providing a glue-passing hole 41 on the glue-fixing block 40, and by using the glue-fixing cylinder 42 and the glue-fixing pressure block 43 to cooperate, the glue-passing hole 41 can be opened or closed. This facilitates the glue-fixing and cutting of the tape and the glue-passing extension, thereby improving the automation rate and the smoothness of tape application.

[0025] An auxiliary adhesive application roller 27 and an auxiliary adhesive application bracket 28 are provided on the adhesive application block 26. The auxiliary adhesive application roller 27 is rotatably mounted on the auxiliary adhesive application bracket 28 and is located above the adhesive application block 26, contacting the upper surface of the adhesive application block 26. In this embodiment, the auxiliary adhesive application roller 27 is provided on the adhesive application block 26 to prevent the adhesive tape from lifting during application, thereby improving the application effect.
