Description
Technical Field
[0001] This utility model relates to the field of battery technology, specifically to a hook-assisted insulating cap holding device and a cell welding and forming machine. Background Technology
[0002] In the battery manufacturing process, the positive and negative terminals of the battery must be strictly insulated to avoid open circuits caused by internal or external contact. Insulating caps are usually installed on the battery terminals (such as the top of cylindrical batteries or the tabs of square batteries) to block direct contact between metal parts and the external environment, thereby preventing the risk of short circuits caused by collisions, squeezing or foreign object intrusion.
[0003] However, during the process of assembling the battery cells and insulating caps and moving them to different workstations, the insulating caps are prone to detaching from the battery cells, which seriously affects the battery assembly efficiency. Utility Model Content
[0004] Based on the above-mentioned technical problems, this utility model provides a hook-assisted insulating cap holding device and a cell welding forming machine to reduce the occurrence of insulating caps falling off the cells, thereby at least partially solving the above-mentioned technical problems.
[0005] In a first aspect, this utility model provides a hook-assisted insulating cap holding device, comprising: a support mechanism for supporting a battery cell assembly, the battery cell assembly including a battery cell body and an insulating cap located on one side thereof; a pressing mechanism connected to the support mechanism for pressing the battery cell body together with the support mechanism; a driving mechanism including a first driving member and a second driving member connected to the support mechanism; and a holding mechanism including a plurality of hooks spaced apart along a third direction, each hook including a holding portion located at one end thereof, the plurality of hooks being configured to move along a first direction via the first driving member and along a second direction via the second driving member, so as to attach the holding portion to the side of the insulating cap opposite to the battery cell body.
[0006] Secondly, this utility model provides a battery cell welding and forming machine, including a feeding mechanism and a hook-assisted insulating cap holding device as described above; the feeding mechanism includes a main body and a plurality of first through slots spaced apart along a third direction in the main body, and the holding part of the hook can be inserted into the first through slot one by one.
[0007] Through the above technical solution, namely the hook-assisted insulating cap holding device provided by this utility model, after the battery cell body is connected to the insulating cap, the battery cell body can be initially positioned by pressing the battery cell body together through a pressing mechanism and a supporting mechanism. Then, a first driving member drives multiple hooks to move along a first direction, and a second driving member drives multiple hooks to move along a second direction. At this time, the holding parts of the multiple hooks can be attached to the side of the insulating cap away from the battery cell body. That is, at this time, the opposite sides of the insulating cap are clamped and fixed by the holding parts and the battery cell body respectively. In this state, the hook-assisted insulating cap holding device can move synchronously with the battery cell assembly. That is, the battery cell assembly can be moved to different workstations for assembly operations directly by moving the hook-assisted insulating cap holding device. During the movement, the holding parts can always be attached to the side of the insulating cap away from the battery cell body, thereby preventing the insulating cap from falling off the battery cell body and improving the battery assembly efficiency.

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0012] In the battery manufacturing process, the positive and negative terminals of the battery must be strictly insulated to avoid open circuits caused by internal or external contact. Insulating caps are usually installed on the battery terminals (such as the top of cylindrical batteries or the tabs of square batteries) to block direct contact between metal parts and the external environment, thereby preventing the risk of short circuits caused by collisions, squeezing or foreign object intrusion.
[0013] However, during the process of assembling the battery cells and insulating caps and moving them to different workstations, the insulating caps are prone to detaching from the battery cells, which seriously affects the battery assembly efficiency.
[0014] In this utility model, an XYZ three-axis coordinate system is established for the hook-assisted insulating cap holding device and the cell welding forming machine, with reference to... Figures 1 to 5 As shown, the direction pointed to by the X arrow can be the first direction as described below, the direction pointed to by the Y arrow can be the second direction as described below, and the direction pointed to by the Z arrow can be the third direction as described below.
[0015] Based on the above-mentioned technical problems, the first aspect of this utility model provides a hook-assisted insulating cap retaining device, as shown in the reference. Figures 1 to 5As shown, the hook-assisted insulating cap retaining device includes a support mechanism 1, a pressing mechanism 2, a driving mechanism 3, and a retaining mechanism 4. The support mechanism supports the battery cell assembly 5, which includes a battery cell body 510 and an insulating cap 520 located on one side thereof. The pressing mechanism 2 is connected to the support mechanism 1 and is used to press the battery cell body 510 together with the support mechanism 1. The driving mechanism 3 includes a first driving member 310 and a second driving member 320 connected to the support mechanism 1. The retaining mechanism 4 includes a plurality of hooks 410 arranged at intervals along a third direction. Each hook 410 includes a retaining portion 411 located at one end. The plurality of hooks 410 are configured to move along a first direction via the first driving member 310 and along a second direction via the second driving member 320 to attach the retaining portion 411 to the side of the insulating cap 520 away from the battery cell body 510.
[0016] Through the above technical solution, namely the hook-assisted insulating cap holding device provided by this utility model, after the battery cell body 510 is connected to the insulating cap 520, the battery cell body 510 can be initially positioned by the pressing mechanism 2 and the supporting mechanism 1 pressing together. Then, the first driving member 310 drives multiple hooks 410 to move along the first direction, and the second driving member 320 drives multiple hooks 410 to move along the second direction. At this time, the holding part 411 of the multiple hooks 410 can be attached to the insulating cap 520 and away from the battery cell body 510. On one side of 0, that is, at this time, the opposite sides of the insulating cap 520 are clamped and fixed by the holding part 411 and the cell body 510 respectively. In this state, the hook-assisted insulating cap holding device can move synchronously with the cell assembly 5. That is, the cell assembly 5 can be moved to different work positions for assembly operations by moving the hook-assisted insulating cap holding device. During the movement, the holding part 411 can always be attached to the side of the insulating cap 520 away from the cell body 510, thereby preventing the insulating cap 520 from falling off the cell body 510 and improving the battery assembly efficiency.
[0017] In some implementations, reference Figures 1 to 5 As shown, the pressing mechanism 2 includes a rotating shaft 210 and a rotating component 210. The rotating shaft 210 is connected to the support mechanism 1; the rotating component 220 is rotatably connected to the rotating shaft 210 and is provided with a pressing surface 221.
[0018] In the above manner, when the pressing mechanism 2 presses the battery cell body 510, the pressing surface 221 can rotate relative to the rotating shaft 210, that is, when the pressing mechanism 220 rotates to the surface of the battery cell body 510, it can work with the support mechanism 1 to press the battery cell body 510 together, thereby fixing the battery cell body 510. When the battery cell body 510 needs to be removed from the support mechanism 1, the pressing surface 221 can be removed from the surface of the battery cell body 510 by rotating the pressing mechanism 220 relative to the rotating shaft 210, so that the pressing surface 221 is no longer located above the surface of the battery cell body 510, and the battery cell body 510 can be removed.
[0019] In some implementations, reference Figures 1 to 5 As shown, the rotating component 220 includes a rotating rod 222 and a pressure block 223. One end of the rotating rod 222 is rotatably connected to the rotating shaft 210, and the other end is connected to the pressure block 223. The pressing surface 221 is formed on the side of the pressure block 223 facing the support mechanism 1.
[0020] By means of the above method, the pressing surface 221 formed on the surface of the pressing block 223 can improve the stability of pressing the battery cell body 510, that is, as Figure 1 As shown, the pressing surface 221 of the pressing block 223 facing the cell body 510 has a larger surface area, which can improve the pressing stability when pressing the cell body 510 and prevent the cell body 510 from shaking.
[0021] In some implementations, reference Figures 1 to 5 As shown, the pressing mechanism 2 also includes a limiting member 230 connected to the support mechanism 1. The limiting member and the rotating member 220 are both located on the same side of the support mechanism 1. The limiting member 230 is used to limit the rotation of the rotating member 220.
[0022] In the above manner, the limiting member 230 can limit the rotation of the rotating member 220. That is, the limiting member 230 can be a limiting plate connected to the support mechanism 1. When the rotating member 220 rotates at a certain angle relative to the rotating shaft 210, the limiting member 230 can limit the rotation of the rotating member 220, thereby preventing the rotating member 220 from rotating randomly and damaging other equipment in the hook-assisted insulating cap holding device. (Refer to...) Figure 1 As shown, when the pressing surface 221 is pressed against the cell body 510, the rotating member 220 can be limited by the limiting member 230 after rotating 90° clockwise relative to the rotating shaft 210.
[0023] In some implementations, reference Figures 1 to 5 As shown, the first driving component 310 is configured as a first cylinder or a first linear drive motor.
[0024] In the above manner, when the first driving component 310 adopts the first cylinder or the first linear drive motor, it can drive multiple hooks 410 to move stably along the first direction.
[0025] In some implementations, reference Figures 1 to 5 As shown, the second drive unit 320 is configured as a second cylinder or a second linear drive motor.
[0026] In this way, when the second driving component 320 adopts a second cylinder or a second linear drive motor, it can drive multiple hooks 410 to move stably along the second direction.
[0027] In a second aspect, this utility model provides a battery cell welding and forming machine, which includes a feeding mechanism 6 and a hook-assisted insulating cap holding device mentioned in the above embodiments, and has all the beneficial effects of the above embodiments. The feeding mechanism 6 includes a main body 610 and a plurality of first through slots 620 arranged at intervals along a third direction in the main body 610. The holding part 411 of the hook 410 can be inserted into the first through slot 620 one by one.
[0028] In the above manner, when the feeding mechanism 6 feeds the insulating cap 520, the feeding mechanism 6 can first bring the insulating cap 520 close to the battery cell body 510. After the insulating cap 520 is close to the battery cell body 510 and assembled with the battery cell body 510, the holding parts 411 of the multiple hooks 410 can be inserted into the multiple first through slots 620 one by one. At this time, the main body 610 can be removed, and the insulating cap 520 can be held and fixed by the holding parts 411.
[0029] It can be understood that the first through slot 620 is designed to better cooperate with the retaining part 411 of the multiple claws 410 so as to enable the movement, clamping and fixing of the insulating cap 520.
[0030] In order to better move the insulating cap 520, refer to Figures 1 to 5 As shown, the feeding mechanism 6 also includes a mounting groove 630 that communicates with a plurality of first through grooves 620, and the mounting groove 630 is used to install the insulating cap 520.
[0031] In this way, the mounting slot 630 can more stably drive the insulating cap 520 to move, and can also better achieve the assembly and positioning with the battery cell body 510.
[0032] Specifically, refer to Figures 1 to 5 As shown, the mounting slot 630 extends along a third direction.
[0033] The mounting slot 630 is matched with the arrangement of multiple hooks 410. In this arrangement, when the main body 610 of the feeding mechanism 6 drives the insulating cap 520 to assemble with the battery cell body 510, it can cooperate with multiple hooks 410 more quickly and conveniently, improving the efficiency of moving and fixing the insulating cap 520.
[0034] In some implementations, reference Figures 1 to 5 As shown, the extension length of the mounting groove 630 along the third direction is less than the length of the main body 610 in the third direction.
[0035] In this way, the mounting groove 630 is not through in the third direction. When the insulating cap 520 is installed in the mounting groove 630 and the insulating cap 520 is moved, the movement of the insulating cap 520 in the third direction can be reduced. In addition, the non-through structure of the mounting groove 630 can also prevent the insulating cap 520 from detaching from the mounting groove 630 in the third direction, thereby improving the stability during the movement of the insulating cap 520.
[0036] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
