The transfer device has a first direction x, a second direction y, and a third direction z that intersect pairwise. The transfer device includes: a frame 100, a first driving mechanism 200, and a grasping mechanism 300.

[0042] It should be noted that in this embodiment, the first direction x is Figure 1 the direction indicated by x in Figure 1 the direction indicated by y in Figure 1 the direction indicated by z in

[0043] In the above transfer device, the battery pack is placed below the grasping mechanism 300, and the plug of the battery pack is placed facing the grasping mechanism 300. The first driving member 310 is used to drive the first jaw 321 and the second jaw 322 to move away from each other, and the first driving mechanism 200 is used to drive the grasping mechanism 300 to move along the third direction z towards the direction close to the battery pack, so that the grasping mechanism 300 can descend to the position where the battery pack is located, and the first jaw 321 and the second jaw 322 are respectively located on both sides of the plug. Then, the first driving member 310 is used to drive the first jaw 321 and the second jaw 322 to move closer to each other, so that the first jaw 321 and the second jaw 322 can clamp the plug located between them. Finally, the first driving mechanism 200 is used to drive the grasping mechanism 300 to move along the third direction z towards the direction away from the battery pack to realize the separation of the plug from the battery cell, thereby realizing the automatic cleaning of the plug in the battery pack, facilitating the subsequent transfer process. In this way, the above transfer device can improve the efficiency of cleaning the plug of the battery pack, does not require manual cleaning, effectively avoids missed cleaning of the plug, and thus improves the transfer efficiency of the battery pack.

[0044] Refer to Figure 4As shown, a first limiting groove 3211 is formed on a side surface of the first clamping jaw 321 close to the second clamping jaw 322 along the second direction y. The opening of the first limiting groove 3211 faces the second clamping jaw 322, and the first limiting groove 3211 is recessed away from the second clamping jaw 322. The first limiting groove 3211 extends along the first direction x.

[0045] In this embodiment, since the opening of the first limiting groove 3211 faces the second clamping jaw 322, the first limiting groove 3211 is recessed away from the second clamping jaw 322, and the first limiting groove 3211 extends along the first direction x. Thus, when clamping the plug piece, the convex portion on the side of the plug piece close to the first clamping jaw 321 can be located in the first limiting groove 3211, so as to limit the plug piece through the first limiting groove 3211, improve the friction between the grasping assembly 320 and the plug piece, facilitate the grasping assembly 320 to grasp the plug piece, and thus realize the separation of the plug piece from the battery cell.

[0046] Refer to Figure 5 As shown, a second limiting groove 3221 is formed on a side surface of the second clamping jaw 322 close to the first clamping jaw 321 along the second direction y. The opening of the second limiting groove 3221 faces the first clamping jaw 321, and the second limiting groove 3221 is recessed away from the first clamping jaw 321. The second limiting groove 3221 extends along the first direction x.

[0047] In this embodiment, since the opening of the second limiting groove 3221 faces the first clamping jaw 321, the second limiting groove 3221 is recessed away from the first clamping jaw 321, and the second limiting groove 3221 extends along the first direction x. Thus, when clamping the plug piece, the convex portion on the side of the plug piece close to the second clamping jaw 322 can be located in the second limiting groove 3221, so as to further limit the plug piece through the second limiting groove 3221, further improve the friction between the grasping assembly 320 and the plug piece, facilitate the grasping assembly 320 to grasp the plug piece, and thus realize the separation of the plug piece from the battery cell.

[0048] Refer to Figure 3 As shown, the first driving mechanism 200 includes a second driving member 210 and a connecting member 220. The second driving member 210 is arranged on the frame 100 and is connected to the connecting member 220. The grasping mechanism 300 is connected to the connecting member 220. The second driving member 210 is used to drive the connecting member 220 to move along the third direction z.

[0049] In this embodiment, the second driving member 210 can drive the connecting member 220 to move along the third direction z, so that the connecting member 220 drives the grasping mechanism 300 to move along the third direction z. When the second driving member 210 drives the connecting member 220 to move along the third direction z towards the direction close to the battery pack, the grasping mechanism 300 can be lowered to the position where the battery pack is located, so as to facilitate the grasping component 320 to grasp the plug. After the grasping component 320 grasps and fixes the plug, the second driving member 210 can drive the connecting member 220 to move along the third direction z towards the direction away from the battery pack, so that the plug can move along the third direction z towards the direction away from the battery pack with the grasping mechanism 300, so as to realize the separation of the plug from the battery cell, thereby realizing the automatic cleaning of the plug in the battery pack.

[0050] Continue to refer to Figure 3 As shown, the number of the grasping mechanisms 300 is multiple, and the multiple grasping mechanisms 300 are arranged on the connecting member 220 at intervals along the second direction y, and each grasping mechanism 300 is used to clean one plug.

[0051] Specifically, continue to refer to Figure 3 As shown, the connecting member 220 includes a first connecting portion 221 and a second connecting portion 222. The first connecting portion 221 extends along the third direction z, and both ends of the first connecting portion 221 along the third direction z are respectively connected to the second driving member 210 and the second connecting portion 222. The second connecting portion 222 extends along the second direction y, and each grasping mechanism 300 is connected to the second connecting portion 222. When the second driving member 210 drives the first connecting portion 221 to move along the third direction z, the second connecting portion 222 can be driven to move along the third direction z through the first connecting portion 221, so as to drive the multiple grasping mechanisms 300 to move synchronously along the third direction z through the second connecting portion 222.

[0052] In this embodiment, since the multiple grasping mechanisms 300 are arranged on the connecting member 220 at intervals along the second direction y, and each grasping mechanism 300 is used to clean one plug. Thus, when the second driving member 210 drives the connecting member 220 to move along the third direction z towards the direction close to the battery pack, the multiple grasping mechanisms 300 can be lowered to the position where the battery pack is located, so as to facilitate the simultaneous grasping of multiple plugs by the multiple grasping components 320, thereby improving the cleaning efficiency of the plugs in the battery pack.

[0053] Continue to refer to Figure 3 As shown, the transfer device further includes a first guiding component 400. The first guiding component 400 is connected to the frame 100, and the first guiding component 400 is slidably connected to the connecting member 220. The connecting member 220 is used to slide relative to the first guiding component 400 along the third direction z.

[0054] Specifically, refer toFigure 3 As shown, the first guiding assembly 400 includes a first guiding member 410 and a first bracket 420. The first bracket 420 is connected to the frame 100, and the first guiding member 410 is connected to the first bracket 420. The first guiding member 410 extends along the third direction z. The connecting member 220 further includes a third connecting portion 223. The third connecting portion 223 is connected to the second connecting portion 222 and extends along the third direction z. The third connecting portion 223 is slidably connected to the first guiding member 410 and is used to slide relative to the first guiding member 410 along the third direction z. In this way, the first guiding member 410 can guide the sliding of the third connecting portion 223 to ensure that the third connecting portion 223 can slide along the third direction z, so as to ensure that the second connecting portion 222 connected to the third connecting portion 223 can slide along the third direction z, thereby improving the smoothness of the movement of the second driving member 210 driving the connecting member 220 to move along the third direction z.

[0055] In this embodiment, since the first guiding assembly 400 is slidably connected to the connecting member 220 and the connecting member 220 is used to slide relative to the first guiding assembly 400 along the third direction z, the first guiding assembly 400 can guide the sliding of the connecting member 220 to ensure that the connecting member 220 can slide along the third direction z, thereby improving the smoothness of the movement of the second driving member 210 driving the connecting member 220 to move along the third direction z.

[0056] Specifically, referring to Figure 3 As shown, there are two first guiding assemblies 400, and the two first guiding assemblies 400 are respectively arranged on both sides of the second driving member 210 along the second direction y to ensure that the first guiding assemblies 400 can guide both ends of the connecting member 220 along the second direction y, thereby improving the balance of the guiding of the first guiding assemblies 400 to the connecting member 220.

[0057] Referring to Figure 1 and Figure 2 As shown, the transfer device further includes a transfer mechanism 500 and a second driving mechanism 600. The second driving mechanism 600 is arranged on the frame 100. The transfer mechanism 500 includes an anti-falling component 510. The second driving mechanism 600 is connected to the anti-falling component 510 and is used to drive the anti-falling component 510 to move along the first direction x, the second direction y, and the third direction z.

[0058] In this embodiment, after the gripping mechanism 300 removes the plug on the battery pack, the transfer mechanism 500 can transfer the battery pack so that the battery pack is transferred to the next process. Since the second driving mechanism 600 is connected to the anti-drop component 510 and is used to drive the anti-drop component 510 to move in the first direction x, the second direction y, and the third direction z, thus, the second driving mechanism 600 can drive the anti-drop component 510 to move in the first direction x, the second direction y, and the third direction z, so that the anti-drop component 510 can be located around the battery pack, thereby protecting the battery pack by the anti-drop component 510 and preventing the battery pack from falling off the transfer mechanism 500, improving the safety of the transfer process.

[0059] Referring to Figure 6 and Figure 7 As shown, the second driving mechanism 600 includes a third driving member 610 and a fourth driving member 620 arranged in parallel with the third driving member 610. The anti-drop component 510 includes a first anti-drop member 511 and a second anti-drop member 512 spaced apart from the first anti-drop member 511 in the first direction x. The third driving member 610 is connected to the first anti-drop member 511 and is used to drive the first anti-drop member 511 to move in the first direction x. The fourth driving member 620 is connected to the second anti-drop member 512 and is used to drive the second anti-drop member 512 to move in the first direction x.

[0060] In this embodiment, during the transfer of the battery pack, the battery pack is located between the first anti-falling member 511 and the second anti-falling member 512. Before the transfer of the battery pack, the third driving member 610 can be used to drive the first anti-falling member 511 to move in the first direction x away from the second anti-falling member 512, and at the same time, the fourth driving member 620 is used to drive the second anti-falling member 512 to move in the first direction x away from the first anti-falling member 511, so that the first anti-falling member 511 and the second anti-falling member 512 can move away from each other to vacate a position for fixing the battery pack, facilitating the subsequent connection of the battery pack to the transfer mechanism 500 and avoiding interference between the first anti-falling member 511 and the second anti-falling member 512 and the battery pack. When the battery pack is being transferred, the third driving member 610 can be used to drive the first anti-falling member 511 to move in the first direction x towards the second anti-falling member 512, and at the same time, the fourth driving member 620 is used to drive the second anti-falling member 512 to move in the first direction x towards the first anti-falling member 511, so that the first anti-falling member 511 and the second anti-falling member 512 can move closer to each other, so that both the first anti-falling member 511 and the second anti-falling member 512 can approach the battery pack, so that the first anti-falling member 511 and the second anti-falling member 512 surround the periphery of the battery pack, thereby protecting the battery pack by the first anti-falling member 511 and the second anti-falling member 512 and preventing the battery pack from falling off the transfer mechanism 500.

[0061] Referring to Figure 6 and Figure 7 As shown, the second driving mechanism 600 further includes a fifth driving member 630. The fifth driving member 630 is disposed on the frame 100, and both the third driving member 610 and the fourth driving member 620 are connected to the fifth driving member 630. The fifth driving member 630 is used to drive the third driving member 610 and the fourth driving member 620 to move synchronously in the third direction z.

[0062] In this embodiment, before transporting the battery pack, the fifth driving member 630 can drive the third driving member 610 and the fourth driving member 620 to move synchronously in the third direction z towards the direction close to the frame 100, so as to drive the first anti-falling member 511 and the second anti-falling member 512 to move synchronously in the third direction z towards the direction close to the frame 100, thereby avoiding the position for fixing the battery pack and facilitating the subsequent connection of the battery pack with the transfer mechanism 500, and preventing interference between the first anti-falling member 511 and the second anti-falling member 512 and the battery pack. When transporting the battery pack, the fifth driving member 630 can drive the third driving member 610 and the fourth driving member 620 to move synchronously in the third direction z towards the direction away from the frame 100, so as to drive the first anti-falling member 511 and the second anti-falling member 512 to move synchronously in the third direction z towards the direction away from the frame 100, that is, towards the bottom of the battery pack. The first anti-falling member 511 and the second anti-falling member 512 can surround the periphery of the battery pack along the third direction z away from the frame 100. In this way, the first anti-falling member 511 and the second anti-falling member 512 can surround the periphery of the battery pack along the first direction x, the second direction y, and the third direction z, so as to protect the battery pack through the first anti-falling member 511 and the second anti-falling member 512, prevent the battery pack from falling off the transfer mechanism 500, and improve the safety of the transportation process.

[0063] Refer to Figure 6 , Figure 8 and Figure 9As shown, the transfer mechanism 500 further includes a fixing member 520.

The fifth anti-falling portion 5122 is connected to one end of the fourth anti-falling portion 5121 away from the frame 100 along the third direction z, and the fifth anti-falling portion 5122 extends along the first direction x towards the first anti-falling member 511. Both ends of the fourth anti-falling portion 5121 along the second direction y are connected with a sixth anti-falling portion 5123. Each sixth anti-falling portion 5123 extends along the third direction z, and each sixth anti-falling portion 5123 is connected to a fourth driving member 620.

[0064] Specifically, in this embodiment, the fixing member 520 and the battery pack are fixed by vacuum adsorption.

[0065] In this embodiment, one end of the battery pack along the third direction z is connected to the fixing member 520. When the fifth driving member 630 drives the third driving member 610 and the fourth driving member 620 to synchronously move away from the frame 100 along the third direction z, the second anti-falling portion 5112 and the fifth anti-falling portion 5122 can be located at one end of the battery pack along the third direction z away from the fixing member 520. In this way, the protection of the battery pack in the third direction z can be achieved. When the third driving member 610 drives the first anti-falling member 511 to approach the second anti-falling member 512 along the first direction x, and the fourth driving member 620 drives the second anti-falling member 512 to approach the first anti-falling member 511 along the first direction x, the first anti-falling portion 5111 and the fourth anti-falling portion 5121 can be located at both ends of the battery pack along the first direction x respectively, so as to achieve the protection of the battery pack in the first direction x. At the same time, the two third anti-falling portions 5113 can be located at both ends of the battery pack along the second direction y respectively, and the two sixth anti-falling portions 5123 can be located at both ends of the battery pack along the second direction y respectively, so as to achieve the protection of the battery pack in the second direction y. In this way, the first anti-falling member 511 and the second anti-falling member 512 can surround the periphery of the battery pack along the first direction x, the second direction y and the third direction z, so as to protect the battery pack through the first anti-falling member 511 and the second anti-falling member 512, and avoid the battery pack from falling off the transfer mechanism 500, thereby improving the safety of the transfer process.

[0066] Referring to Figure 6 and Figure 7 As shown, the second driving mechanism 600 further includes a first connecting plate 640. The first connecting plate 640 extends along the third direction z. One end of the first connecting plate 640 along the third direction z is connected to the driving end of the fifth driving member 630, and the third driving member 610 and the fourth driving member 620 are both connected to the first connecting plate 640.

[0067] In this embodiment, since the first connecting plate 640 extends along the third direction z, and one end of the first connecting plate 640 along the third direction z is connected to the driving end of the fifth driving member 630, in this way, the first connecting plate 640 can be driven by the fifth driving end to move along the third direction z. Also, since the third driving member 610 and the fourth driving member 620 are both connected to the first connecting plate 640, when the first connecting plate 640 moves along the third direction z, the third driving member 610 and the fourth driving member 620 can be driven by the first connecting plate 640 to move synchronously along the third direction z, so as to realize the synchronous movement of the first anti-falling member 511 and the second anti-falling member 512 along the third direction z.

[0068] Continuing to refer to Figure 6 and Figure 7As shown, the second driving mechanism 600 further includes a second connecting plate 650. The third driving member 610 and the fourth driving member 620 are both connected to the second connecting plate 650. The transfer device further includes a second guiding assembly 700. The second guiding assembly 700 is arranged on the frame 100. The second connecting plate 650 is connected to the first connecting plate 640 and is slidably connected to the second guiding assembly 700. Moreover, the second connecting plate 650 is used to slide along the third direction z relative to the second guiding assembly 700.

[0069] Specifically, referring to Figure 7 As shown, the second guiding assembly 700 includes a second guiding member 710 and a second bracket 720. The second bracket 720 is connected to the frame 100. The second guiding member 710 is connected to the second bracket 720. And the second guiding member 710 extends along the third direction z. The second connecting plate 650 is slidably connected to the second guiding member 710. Moreover, the second connecting plate 650 is used to slide along the third direction z relative to the second guiding member 710. In this way, the second guiding member 710 can play a guiding role in the sliding of the second connecting plate 650 to ensure that the second connecting plate 650 can slide along the third direction z, so as to ensure that the third driving member 610 and the fourth driving member 620 connected to the second connecting plate 650 can slide along the third direction z, thereby improving the movement smoothness when the fifth driving member 630 drives the third driving member 610 and the fourth driving member 620 to move along the third direction z.

[0070] In this embodiment, since the second connecting plate 650 is connected to the first connecting plate 640, and the third driving member 610 and the fourth driving member 620 are both connected to the second connecting plate 650. In this way, when the fifth driving member 630 drives the first connecting plate 640 to move along the third direction z, the first connecting plate 640 can drive the second connecting plate 650 to move along the third direction z, and then drive the third driving member 610 and the fourth driving member 620 to move synchronously along the third direction z through the second connecting plate 650. During this process, since the second connecting plate 650 is slidably connected to the second guiding assembly 700, and the second connecting plate 650 is used to slide along the third direction z relative to the second guiding assembly 700. In this way, the second guiding assembly 700 can play a guiding role in the sliding of the second connecting plate 650 to ensure that the second connecting plate 650 can slide along the third direction z, so as to ensure that the third driving member 610 and the fourth driving member 620 connected to the second connecting plate 650 can slide along the third direction z, thereby improving the movement smoothness when the fifth driving member 630 drives the third driving member 610 and the fourth driving member 620 to move along the third direction z.
