[0043] Figure 1This diagram shows the structure of the battery cell gripping device provided in an embodiment of the present invention. Figure 2 This diagram shows a partial structural schematic of the battery cell gripping device provided in an embodiment of the present invention. In the diagram, the X, Y, and Z directions are arranged perpendicularly to each other. (Refer to...) Figure 1 and Figure 2 This embodiment provides a battery cell gripping device. The battery cell gripping device includes a support base 100, a first gripping mechanism 200, and a second gripping mechanism 300.

[0044] Specifically, the first gripping mechanism 200 is vertically and flexibly connected to the support base 100, capable of gripping the blister tray 10, which carries multiple battery cells 20. The second gripping mechanism 300 is disposed on the support base 100 and includes multiple battery cell adsorption components. Each battery cell adsorption component corresponds one-to-one with a battery cell 20 and can adsorb the corresponding battery cell 20. The spacing between the multiple battery cell adsorption components is adjustable. Through the first gripping mechanism 200, the blister tray 10 can be gripped, and the blister tray 10 can be moved and retrieved. By adjusting the spacing between the multiple battery cell adsorption components in the second gripping mechanism 300, the battery cell gripping device can be adapted to simultaneously grip multiple battery cells 20 with different placement spacings on the blister tray 10, which is beneficial to improving flexibility and expanding the scope of application.

[0045] It should be noted that the spacing direction of the aforementioned multiple battery cell adsorption components is angled to the lifting direction of the first gripping mechanism 200. This allows the battery cell gripping device to simultaneously integrate the gripping function of the battery cell 20 and the recycling function of the blister pack 10, thus reducing the space occupied by the battery cell gripping device. In this embodiment, the lifting direction of the first gripping mechanism 200 is the Z direction, and the spacing direction of the multiple battery cell adsorption components is the X direction.

[0046] Continue to refer to Figure 1 and Figure 2 The first gripping mechanism 200 includes a first driving component 210 and a first adsorption component 220. The first driving component 210 is mounted on the support base 100, and the first adsorption component 220 is connected to the output end of the first driving component 210. It can adsorb onto the blister pack 10 and move along the Z-direction under the drive of the first driving component 210. In this embodiment, the first driving component 210 can specifically be a cylinder, with its cylinder body fixedly mounted on the support base 100. The first adsorption component 220 is connected to the telescopic end of the cylinder, which can extend and retract relative to the cylinder body along the Z-direction.

[0047] Specifically, the first adsorption assembly 220 includes a first displacement plate 221 and a first adsorption member 222. The first displacement plate 221 is connected to the output end of the first driving assembly 210, and the first adsorption member 222 is connected to the first displacement plate 221. The first adsorption member 222 can adsorb and connect to the blister tray 10. The first displacement plate 221 can provide a stable and reliable installation position for the first adsorption member 222, improving the connection reliability between the first adsorption member 222 and the first driving assembly 210 and the stability of the first adsorption member 222 when adsorbing the blister tray 10. In this embodiment, the first adsorption member 222 can specifically be a suction cup from the prior art.

[0048] More specifically, there are multiple first adsorption elements 222, which are adjustablely spaced along the length of the first displacement plate 221. Using multiple first adsorption elements 222 to adsorb the blister pack 10 ensures the stability and reliability of the adsorption. In this embodiment, two first adsorption elements 222 are specifically spaced apart on one first displacement plate 221. Furthermore, by adjusting the position of the first adsorption elements 222 on the first displacement plate 221, it can be adapted to adsorb blister packs 10 of different sizes, expanding the applicability and flexibility of the battery cell gripping device.

[0049] In this embodiment, the first displacement plate 221 extends along the X direction, and in order to ensure the stability of the first displacement plate 221, a plurality of first driving components 210 are provided to move the position of the first displacement plate 221. In this embodiment, there are specifically two first driving components 210, which are spaced apart in the X direction.

[0050] Optionally, the first displacement plate 221 has a connecting elongated hole 2211, the length direction of which is parallel to the extending direction of the first displacement plate 221. The first adsorption member 222 is adjustablely connected to the connecting elongated hole 2211 along its length direction. In this embodiment, the connecting rod portion of the first adsorption member 222 has an external thread, and the connecting rod portion passes through the connecting elongated hole 2211. By using two nuts screwed onto the connecting rod portion to fasten it on both sides of the first displacement plate 221, the position of the first adsorption member 222 in the connecting elongated hole 2211 can be fixed.

[0051] More specifically, there are multiple first gripping mechanisms 200, which are spaced apart. The spacing direction of the multiple first gripping mechanisms 200 is angular to the spacing direction of the multiple battery cell adsorption components and the lifting direction of the first gripping mechanisms 200. In this embodiment, two sets of first gripping mechanisms 200 are specifically provided, which are spaced apart along the Y direction. Through the above arrangement, adsorption connection can be made at all four corners of the blister pack 10, thereby ensuring the stability and reliability of the movement of the blister pack 10.

[0052] Continue to refer to Figure 1 and Figure 2 The multiple battery cell adsorption assemblies specifically include a fixed adsorption assembly 310 and movable adsorption assemblies 320 located on both sides of the fixed adsorption assembly 310. The fixed adsorption assembly 310 is fixedly connected to the support base 100, and the movable adsorption assembly 320 is relatively movably connected to the support base 100 to adjust the spacing between the multiple battery cell adsorption assemblies. In this embodiment, the...

[0053] Specifically, the fixed adsorption assembly 310 includes a fixed mounting plate 311 and third adsorption members 312. The fixed mounting plate 311 is fixedly disposed on one side of the support base 100. Multiple third adsorption members 312 are arranged in a rectangular array on the side of the fixed mounting plate 311 opposite to the support base 100. Multiple third adsorption members 312 can simultaneously adsorb one battery cell 20, ensuring the reliability of adsorption and the stability of movement of the corresponding battery cell 20.

[0054] More specifically, the movable adsorption assembly 320 includes a sliding connector 321, a movable mounting plate 322, and a second adsorption member 323. The support base 100 is provided with a slide rail 110 along the X direction. The sliding connector 321 is specifically a slider structure, slidably connected to the slide rail 110. The movable mounting plate 322 is connected to the sliding connector 321, and the second adsorption member 323 is mounted on the movable mounting plate 322, capable of adsorbing the battery cell 20. In this embodiment, there are multiple second adsorption members 323, which can simultaneously adsorb one battery cell 20 to ensure the reliability of adsorption and the stability of the movement process of the corresponding battery cell 20.

[0055] More specifically, the movable adsorption component 320 includes a connecting seat 324. The connecting seat 324 is connected to the sliding connector 321 and is movable relative to the support base 100. The second gripping mechanism 300 also includes a second drive component 330, which is disposed on the support base 100. The connecting seat 324 is connected to the output end of the second drive component 330, and the connecting seat 324 is movable along the X direction under the drive of the second drive component 330, thereby driving the sliding connector 321 to move along the slide rail 110. In this embodiment, the second drive component 330 can specifically be a cylinder from the prior art.

[0056] It should be noted that, corresponding to the two active adsorption components 320, in this embodiment, the second driving component 330 is also set to two, so as to realize the separate adjustment of the distance between the two active adsorption components 320 and the fixed adsorption component 310.

[0057] Preferably, the second gripping mechanism 300 further includes a limiting member 340. The limiting member 340 has a plate-like structure, is disposed on the support base 100, and is relatively fixedly disposed on the side of the fixed mounting plate 311, configured to limit the minimum distance between the movable adsorption assembly 320 and the fixed adsorption assembly 310. The movable mounting plate 322 stops moving when it contacts the limiting member 340 along with the sliding connector 321.

[0058] Furthermore, the limiting member 340 is detachably connected to the support base 100. By replacing the limiting member 340 with different widths, the minimum distance between the movable adsorption component 320 and the fixed adsorption component 310 can be adjusted, thereby adapting to the gripping of battery cells 20 of different sizes and spacings.

[0059] Figure 3 Show Figure 2 A magnified view of a section marked A in the middle; Figure 4 Show Figure 2 A magnified view of the structure marked B in the middle section. (Refer to...) Figures 1-4 The second gripping mechanism 300 further includes a sensing component 350. The sensing component 350 includes a first sensor 351 and a second sensor 352. The first sensor 351 is disposed on the movable adsorption component 320, and the second sensor 352 is disposed on the support base 100 and near its end. When the movable adsorption component 320 moves to the point where the first sensor 351 senses the second sensor 352, the movable adsorption component 320 stops moving. This design prevents the movable adsorption component 320 from moving out of the support base 100.

[0060] Specifically, refer to Figure 3 and Figure 4In this embodiment, the first sensor 351 has an L-shaped plate structure, and the second sensor 352 has a beam-through space 353 in which beam-through light is generated. When the second sensor 352 moves into the beam-through space 353, the beam-through light is blocked, and the second sensor 352 can send a stop signal. At this time, the second driving component 330 stops driving the movable adsorption component 320.

[0061] The battery cell gripping device also includes a displacement drive mechanism. The support base 100 is connected to the displacement drive mechanism and can move under the drive of the displacement drive mechanism, thereby realizing the transfer of the blister tray 10 and the battery cell 20. In this embodiment, the displacement drive mechanism can be a device with multiple degrees of freedom, such as a robotic arm, as long as it can realize the movement of the position of the support base 100. Its specific type and structure are not limited in this embodiment.

[0062] The usage process of the battery cell gripping device provided in this embodiment is as follows:

[0063] When gripping the battery cell 20, the displacement drive mechanism drives the carrier 100 to the battery cell 20 feeding device. Then, the battery cell gripping device uses the first gripping mechanism 200 and the second gripping mechanism 300 to respectively adsorb and grip the blister tray 10 and the battery cell 20, and move them together to the blister tray collection station. Then, after stacking the blister tray 10 on the blister tray collection station, the battery cell 20 is transferred to the downstream processing station to realize the feeding of the battery cell 20.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
