Description

Technical Field

[0001] This utility model belongs to the technical field of battery manufacturing equipment, specifically relating to a 90° bending mechanism for soft-pack lithium battery FPC flexible boards. Background Technology

[0002] In the battery manufacturing process, to enable flexible connections between the battery and other electronic devices, a flexible printed circuit board (FPC) is typically placed at the battery's head. The FPC itself is relatively thin and flexible, and in its natural state is open. To adapt to the specific structural and functional requirements of the battery, the FPC is usually bent and shaped during battery manufacturing to better fit the battery body. Figure 1 A schematic diagram of the battery and FPC flexible circuit board structure before bending is shown. Figure 2 This is a schematic diagram of the bent battery and FPC soft-pack structure.

[0003] Existing battery FPC flexible circuit board bending mechanisms typically position the loaded battery before moving it to the bending assembly for bending. Because the battery FPC flexible circuit board bending mechanism only positions the battery once without further limiting its movement, the bending assembly may not accurately align with the part of the FPC flexible circuit board to be bent, thus failing to guarantee bending quality. Furthermore, the bending action of the bending assembly is not limited, making it impossible to ensure the consistency of the bending angle of each FPC flexible circuit board.

[0004] In view of this, the present invention aims to provide a 90° bending mechanism for soft-pack lithium battery FPC flexible boards. It limits the battery head through a first limiting unit, which can achieve more accurate alignment bending and improve bending quality. Furthermore, it limits the bending action of the bending module through a second limiting unit, which can control the consistency of the bending angle of each battery FPC flexible board and improve product quality.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] like Figure 2-10 As shown, this utility model discloses a 90° bending mechanism for a soft-pack lithium battery FPC flexible board, including a battery feeding assembly 1 for initial positioning and X-direction transport of the battery, a clamping assembly 2 for Y-direction positioning of the battery, a bending rotation assembly 3 for bending the FPC flexible board, and a bending reference assembly 4 cooperating with the bending rotation assembly 3. The battery feeding assembly 1 is provided with a first limiting unit 11 for limiting the battery, and the bending reference assembly 4 is provided with a second limiting unit 41 for limiting the bending action of the bending rotation assembly 3. In use, the battery with the FPC to be bent at 90 degrees is placed into the battery feeding assembly 1. The first limiting unit 11 further limits the battery, so that the bending assembly can accurately align with the part of the FPC to be bent and perform bending, which can achieve more accurate alignment bending and improve bending quality. Then the battery feeding assembly 1 moves forward along the X direction to the pressing assembly 2 to complete the positioning of the cell head. The bending and rotating assembly 3 extends, presses the FPC, and completes the 90° bending action. During the bending process, the second limiting unit 41 limits the bending action of the bending module, thereby controlling the consistency of the bending angle of each battery FPC and improving product quality.

The bending positioning block 111 is fixed, while the top cover plate 112 and the side push block 113 are movable, thereby limiting batteries of different sizes and achieving more precise limiting. In this utility model, the bending positioning block 111 is generally L-shaped and is used to position the tail and one side of the battery.

A second compression spring 1157 is provided between the second floating block 1155 and the second limiting plate 1156.
