[0031] The first aspect of this application provides a bending mechanism that solves the problem that traditional bending mechanisms cannot enter confined spaces, thus making it impossible to bend the battery head's tabs, adhesive tape, or circuit board. See below for reference. Figures 1 to 13 The bending mechanism described in some embodiments of this application is further illustrated. Additionally, for ease of description below, the bending mechanism will be referred to as having two mutually perpendicular X, Y, and Z directions.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown ( Figure 4 (A schematic diagram showing the tab 810 after bending) The bending mechanism of this application is used to bend the part to be bent at the head of the battery 800. The bending mechanism of this application includes an X-axis moving module 100, a top plug 200 and a bending part 300. The battery 800 includes a bendable component disposed at its head. When the battery 800 is processed and fixed, the X-axis moving module 100, the top insert 200, and the bending component 300 are all disposed above the battery 800. The bending component 300 is connected to the X-axis driving stage 110 of the X-axis moving module 100, and the X-axis moving module 100 can drive the bending component 300 to move along the X-axis. The top insert 200 has a reference edge at its head, and the top insert 200 can move along its own extension direction so that the reference edge contacts or moves away from the bendable component. When the reference edge of the top insert 200 contacts the bendable component, the top insert 200 and the bending component 300 are arranged at intervals in the X-axis. The X-axis moving module can drive the bending component 300 to move toward the top insert 200 to push the bendable component to bend with the reference edge as the crease.

[0033] In the embodiments of this application, the component to be bent can be a tab 810, a circuit board, or adhesive tape. The bending mechanism of this application can bend the tab 810, adhesive tape, or circuit board at the battery head. The following description will take the tab 810 as an example.

[0034] When the tab 810 of the battery head is bent, firstly, the top insert 200 moves along its own extension direction so that the reference edge contacts the tab 810. Then, the X-direction moving module drives the bending component 300 to move towards the top insert 200, pushing the tab 810 to pre-bend along the reference edge. Next, the top insert 200 moves along its own extension direction to move away from the tab 810. Finally, the X-direction moving module drives the bending component 300 to continue moving, pushing the tab 810 to bend further along the reference edge.

[0035] As described above, the bending mechanism of this application can bend the tab 810 by the cooperation of the top plug 200 and the bending part 300. The top plug 200 and the bending part 300 occupy little space and can be accommodated in the narrow space where the battery head is located, or the top plug 200 and the bending part 300 can be directly inserted into the narrow space where the battery head is located, thereby facilitating the bending process of the tab 810 of the battery head.

[0036] As an example, in an embodiment of this application, such as Figure 1 and Figure 4 As shown, the bending mechanism also includes a carrier 600, on which the battery 800 is fixed. Figure 4 As shown, the carrier 600 includes a connecting portion 610 and two processing portions 620, wherein the connecting portion 610 connects between the two processing portions 620, and each processing portion 620 fixes the battery 800. Figure 4 The diagram illustrates that each processing section 620 fixes two batteries 800, and each battery 800 has two tabs 810 at its head. Figure 4 As shown, the four tabs 810 are spaced apart along the Y direction, aligned in the X direction, and staggered in the Z direction. Figure 9 As shown, the head of the battery 800 is located in a narrow space between the connecting portion 610 and the processing portion 620. The top plug 200 and the bending component 300 of this application can be directly inserted into the narrow space where the battery head is located, thereby facilitating the bending of the tab 810 of the battery head.

[0037] Specifically, in the embodiments of this application, such as Figure 1 and Figure 2 As shown, the bending mechanism also includes a first linear drive mechanism (such as...). Figure 2 As shown, the first linear drive mechanism can be a first cylinder 210. The output end of the first cylinder 210 is connected to the top plug 200, and the first cylinder 210 can drive the top plug 200 to move along its own extension direction.

[0038] like Figure 1 and Figure 2 As shown, the bending mechanism also includes a Z-axis moving module 400. The X-axis moving module 100 and the first cylinder 210 are both connected to the Z-axis drive platform 410 of the Z-axis moving module 400. The Z-axis moving module 400 can drive the X-axis moving module 100 and the first cylinder 210 to move along the Z-direction. With this configuration, the Z-axis moving module 400 drives the X-axis moving module 100 and the first cylinder 210 to move along the Z-direction, thereby causing the top insert 200 and the bending component 300 to directly extend (insert) into the narrow space where the battery head is located along the Z-direction, thus facilitating the bending of the tab 810 of the battery head.

[0039] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 2 As shown, the bending mechanism also includes a Y-axis moving module 500. The bottom end of the Z-axis moving module 400 is connected to the Y-axis drive platform 510 of the Y-axis moving module 500, and the Y-axis moving module 500 can drive the Z-axis moving module 400 to move the top insert 200 and the bending piece 300 along the Y direction. This configuration, as shown... Figure 4 As shown, when the bending mechanism of this application processes the battery 800 on one of the processing parts 620, the top plug 200 and the bending part 300 are driven in the Y direction by the Y direction moving module 500 to facilitate the processing of the tabs 810 at different positions (Y direction). The top plug 200 and the bending part 300 are driven in the Z direction by the Z direction moving module 400 to facilitate the processing of the tabs 810 at different heights (Z direction).

[0040] It is worth mentioning that conventional bending mechanisms are not convenient for bending tabs 810 of different heights (Z direction) in a confined space.

[0041] To address this issue, this application utilizes the Z-direction driving of the Z-moving module 400 to facilitate the top plug 200 and the bending component 300 entering the confined space containing the battery head from above, thereby facilitating the bending of the tab 810 on the battery head. Furthermore, the Y-direction driving of the Y-moving module 500 facilitates the processing of tabs 810 at different positions (Y-direction) by the top plug 200 and the bending component 300, and the Z-direction driving of the Z-moving module 400 facilitates the processing of tabs 810 at different heights (Z-direction) by the top plug 200 and the bending component 300.

[0042] In this embodiment, the Z-axis moving module 400, the Y-axis moving module 500, and the X-axis moving module 100 can all be driven by servo motors.

[0043] The following section will describe in detail the specific bending process of the tab 810 of this application.

[0044] like Figure 4 As shown, there is a gap between the connecting portion 610 and the machining portion 620 of the carrier 600. Figure 1 , Figure 4 and Figure 5 As shown, the bending mechanism also includes a second linear drive mechanism and support members 720. When the battery 800 is fixed, the second linear drive mechanism and support members 720 are positioned below the battery 800. The second linear drive mechanism can be a second cylinder 710. The output end of the second cylinder 710 is connected to the two support members 720. The second cylinder 710 can drive the two support members 720 to move in the Z direction, so that the two support members 720 pass through the gap between the connecting part 610 and the processing part 620, and then abut or separate from the head of the battery. The purpose of this arrangement is to provide support to the head of the battery 800 by having the support members 720 abut against the head of the battery 800 before the tab 810 is formally bent. For example, the support members 720 can use PEEK (polyether ether ketone) as the support material, which can meet the electrical isolation requirements while bearing the load required for structural support.

[0045] The following description will take the initial state of the tab 810 as 90° and the bending mechanism of this application bending it from 90° to 90° to a horizontal state as an example.

[0046] like Figure 6 and Figure 7 As shown, in the initial state, the tab 810 extends along the Z direction and is in a vertical position, as... Figure 9 and Figure 10 As shown, the extension direction of the top plug 200 forms a first predetermined angle with the Z direction, and the first predetermined angle is an acute angle, for example, 30°. When the reference edge of the top plug 200 contacts the part to be bent, the X-direction moving module 100 can drive the bending part 300 to move a predetermined distance toward the top plug 200, so as to push the part to be bent to bend by the first predetermined angle.

[0047] like Figure 9 As shown, the extension direction of the bent component 300 forms a second predetermined angle with the Z direction, and the second predetermined angle is an acute angle. Figure 3 and Figure 9As shown, the bent component 300 includes a bending surface S2 and a pressing bending surface S1 adjacent to the bending surface S2. When the reference edge of the top insert 200 contacts the tab 810, the bending surface is positioned facing the top insert 200. The pressing bending surface S1 is positioned below the bent component 300 and is parallel to the X direction. The bending surface S2 is parallel to the top insert 200, and the bending surface S2 can push the tab 810 to bend with the reference edge as the crease.

[0048] The bending process is as follows: First, the top plug-in 200 and the bending piece 300 reach the position of the tab 810 by driving the Z-axis moving module 400 in the Z direction and the Y-axis moving module 500 in the Y direction.

[0049] Next, as Figure 7 As shown, the second cylinder 710 drives the two support members 720 to move along the Z direction, so that the two support members 720 pass through the gap between the connecting part 610 and the processing part 620 respectively, and then abut against the head of the battery 800.

[0050] Next, as Figure 9 As shown, the first cylinder 210 drives the reference edge of the top plug 200 to contact the electrode tab 810. In this embodiment, the head of the top plug 200 is provided with a chamfered structure, and the chamfered structure forms a reference edge, which is parallel to the Y direction.

[0051] Next, as Figure 10 As shown, when the reference edge of the top plug 200 contacts the tab 810, the X-axis moving module 100 drives the bending component 300 to move a predetermined distance toward the top plug 200, so as to push the tab 810 to bend 30°.

[0052] Next, as Figure 11 As shown, the first cylinder 210 drives the reference edge of the top plug 200 away from the tab 810.

[0053] Next, as Figure 12 As shown, the X-axis moving module 100 drives the bending component 300 to continue moving, bending the tab 810 to a horizontal state by 180°.

[0054] Finally, as Figure 13 As shown, the Z-axis moving module 400 drives the bending component 300 to press the tab 810 downwards to shape it. This prevents the tab 810 from springing back.

[0055] According to a second aspect of this application, a battery production system is provided, which includes the bending mechanism described above.

[0056] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the scope of the technology disclosed in this application, or make equivalent substitutions for some of the technical features.
