[0042] The applicant has noticed that existing battery grippers can only grasp a certain specific model of battery. There are various models of batteries manufactured on the battery pilot line or test line. Every time a different model of battery is replaced, it is necessary to design, manufacture and replace the battery gripper. Most battery grippers drive to grasp the battery through a cylinder, and the driving stroke of the cylinder is short, which cannot adapt to the grasping of batteries on the pilot line or test line.

[0043] Based on the above problems, please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of a battery grasping device in an embodiment of the present utility model, Figure 2The structural schematic diagram of the first driving member in an embodiment of the present utility model is shown. The battery grasping device provided by an embodiment of the present utility model includes a first driving member 302, an adjusting assembly, and a grasping assembly.

[0044] Among them, the first driving member 302 includes a first moving member 304 and a second moving member 306; the adjusting assembly includes a first adjusting member 308 and a second adjusting member 310. The first adjusting member 308 is connected to the first moving member 304, and the second adjusting member 310 is connected to the second moving member 306; the grasping assembly includes a first gripper 312 and a second gripper 314. The first gripper 312 is connected to the first adjusting member 308, and the second gripper 314 is connected to the second adjusting member 310; the grasping assembly adjusts the distance between the first gripper 312 and the second gripper 314 through the adjusting assembly. Optionally, the first driving member 302 is a driving cylinder.

[0045] Exemplarily, the second moving member 306 moves along the first direction, the first moving member 304 moves in the opposite direction to the second moving member 306, and the moving strokes of the first moving member 304 and the second moving member 306 are the same. And the first adjusting member 308 is connected to the first moving member 304, and the second adjusting member 310 is connected to the second moving member 306. When the first moving member 304 and the second moving member 306 move in opposite directions, the first adjusting member 308 and the second adjusting member 310 drive the first gripper 312 and the second gripper 314 to move in opposite directions respectively; at this time, the first gripper 312 and the second gripper 314 approach or move away from each other in the first direction, and the distance between the first gripper 312 and the second gripper 314 is adjusted. The installation positions of the first adjusting member 308 and the second adjusting member 310 on the first moving member 304 and the second moving member 306 can adjust the maximum distance and the minimum distance between the first gripper 312 and the second gripper 314. When it is necessary to grasp the battery 50, the first driving member 302 adjusts the distance between the first gripper 312 and the second gripper 314 to be greater than the size of the battery 50 in the first direction, aligns the grasping assembly with the battery 50, and the first driving member 302 drives the grasping assembly to contract and clamp the battery 50, and then transports the battery 50.

[0046] In this embodiment, the first driving member is provided with a first moving member and a second moving member that move away from or towards each other along the first direction, realizing the grasping and releasing of the battery by the grasping assembly; the moving strokes of the first moving member and the second moving member are the same, so the first gripper and the second gripper are symmetric about the first driving member, and the overall balance of the battery grasping device can be ensured when grasping the battery. The first adjusting assembly is respectively connected to the first moving member and the first gripper, and the second adjusting member is respectively connected to the second moving member and the second gripper. By changing the installation position of the adjusting assembly, the distance between the first gripper and the second gripper is changed, and the distance between the grasping assemblies is extended, so that the battery grasping device can be applicable to more types of battery sizes.

[0047] Combined with Figures 1 to 5 As shown, in some embodiments, the surface of the first moving member 304 close to the adjusting member is configured as the first driving mounting surface, and the surface of the second moving member 306 close to the second adjusting member 310 is configured as the second driving mounting surface 318; the surface of the first adjusting member 308 close to the first moving member 304 is configured as the adjusting mounting surface 320, and the surface of the first gripper 312 close to the first adjusting member 308 is configured as the gripper mounting surface 328.

[0048] As Figure 3 、 Figure 4 shown Figure 3 shows a schematic structural view of the first adjusting member in an embodiment of the present invention. Figure 4 shows a schematic connection view of the first driving member and the first adjusting member in an embodiment of the present invention. The first surface of the first adjusting member 308 is the adjusting mounting surface 320. The adjusting mounting surface 320 is provided with a sliding groove 326 in the first direction. The sliding groove 326 is located on the central axis of the adjusting mounting surface 320 and penetrates the adjusting mounting surface 320. On the central axis of the sliding groove 326, there are first mounting holes 322 arranged at intervals. On the concave edge of the sliding groove 326, there are second mounting holes 324 arranged at intervals. Half of the second mounting holes 324 are located in the sliding groove 326, and the other half are located on the adjusting mounting surface 320. The surface of the first moving member 304 close to the adjusting member is configured as the first driving mounting surface. There is a raised block 316 on the first driving mounting surface. The raised block matches the size of the sliding groove 326. The raised block 316 moves along the first direction in the sliding groove 326. There is a threaded hole on the raised block 316. The threaded hole is screwed with the first mounting hole 322, so that the first driving mounting surface is closely attached to the first adjusting surface. The first adjusting member 308 is fixed on the first moving member 304 and keeps balanced; when adjusting the position of the adjusting member, the first mounting holes 322 at different positions are aligned and connected with the threaded holes on the raised block 316. Optionally, there are multiple raised blocks 316 on the first driving mounting surface. When the first driving mounting surface is aligned with the first adjusting surface, the threaded holes on the multiple raised blocks 316 are respectively aligned and screwed with the multiple first mounting holes 322.

[0049] As Figure 5 shown Figure 5The structural schematic diagram of the first gripper in an embodiment of the present utility model is shown. One side of the first gripper 312 close to the first adjusting member 308 is configured as a gripper mounting surface 328. The dimension of the gripper mounting surface 328 in the second direction is larger than that of the first adjusting mounting surface 320. A groove is provided on the gripper mounting surface 328 along the second direction, and the dimension of the groove in the second direction is the same as that of the first adjusting member 308 in the second direction. A plurality of third mounting holes are provided corresponding to the second mounting holes 324. When the second surface of the first adjusting member 308 is closely attached to the gripper mounting surface 328, the second mounting holes 324 and the third mounting holes are aligned, so that the first adjusting member 308 and the first gripper 312 are screwed together. When adjusting the first gripper 312, the second mounting holes 324 and the third mounting holes at different positions are aligned and connected. The first adjusting mounting surface 320 partially coincides with the mounting surface of the first gripper 312, and the coincident part can be adjusted in the first direction; and / or, the first adjusting mounting surface 320 partially coincides with the first driving mounting surface, and the coincident part can be adjusted in the first direction.

[0050] Further, buffer members are provided on the surfaces of the first gripper 312 close to the battery in the first direction and the third direction. The buffer members are used to reduce the pressure when the gripper assembly grabs the battery.

[0051] Optionally, the second adjusting member 310, the second gripper 314 are symmetrically arranged with respect to the first adjusting member 308 and the first gripper 312 about the first driving member 302.

[0052] In this embodiment, by adjusting the connection between the first driving member and the grasping assembly, and adjusting the relative mounting positions of the grasping assembly and the first driving member through a plurality of first mounting holes, second mounting holes and third mounting holes, the distance between the first gripper and the second gripper is changed, so that the grasping assembly can be applied to batteries of more models and sizes; the first moving member and the second moving member move towards or away from each other to clamp and release the battery; on the other hand, the second adjusting member, the second gripper are symmetrically arranged with respect to the first adjusting member and the first gripper about the first driving member. During the process of adjusting the distance between the first gripper and the second gripper, the overall balance of the battery grasping device can be maintained, damage to the battery grasping device and the battery can be avoided, and the overall reliability is improved.

[0053] Please refer to Figure 6 , Figure 6 The structural schematic diagram of the battery grasping device in an embodiment of the present utility model is shown. In some embodiments, the battery grasping device further includes a second driving member 334, which is connected to the side of the first driving member 302 away from the adjusting assembly and is used to adjust the movement of the first driving member 302 in the third direction.

[0054] Exemplarily, the second driving member 334 is a driving cylinder. The piston rod of the second driving member 334 is connected to the surface of the first driving member 302 away from the adjusting assembly. The second driving member 334 drives the first driving member 302 to rise or fall in the third direction through the piston rod. The piston rod of the second driving member 334 is symmetrically provided with a first limiting rod and a second limiting rod along the second direction. One end of the first limiting rod and the second limiting rod is fixed on the second driving member 334, and the other end of the first limiting rod and the second limiting rod is slidably connected to the first driving member 302. When the piston rod of the second driving member 334 drives the first driving member 302 to move, the first limiting rod and the second limiting rod limit the position of the first driving member 302.

[0055] In this embodiment, the first driving member is driven by the second driving member to move in the third direction, and after the battery is clamped, the transfer of the battery is realized; a first limiting rod and a second limiting rod are arranged between the first driving member and the second driving member to prevent the first driving member carrying the battery from swinging during the transfer of the battery, resulting in battery displacement or damage.

[0056] In some embodiments, the battery transfer device provided in an embodiment of the present invention includes the battery gripping device of any other embodiment.

[0057] Among them, the battery transfer device includes a transfer assembly and a tray assembly; the transfer assembly is used to drive the tray assembly to perform a circular motion; the tray assembly is arranged on the transfer assembly, and the tray assembly includes a limiting assembly, and the position of the limiting assembly arranged on the tray assembly can be adjusted, so as to form a battery receiving groove with adjustable size.

[0058] Specifically, the tray assembly is arranged on the transfer assembly, and the tray assembly is provided with a limiting assembly. The limiting assembly can adjust its position on the tray assembly along the first direction and the second direction. The limiting assemblies form a battery receiving groove, and the size of the battery receiving groove can be adjusted according to the size of the battery 50, and the position of the battery 50 on the transfer assembly is restricted. The empty tray assembly can follow the transfer assembly to perform a circular motion. The column of the battery detection device straddles the battery transfer device in the second direction, and the test platform is arranged above the battery transfer device.

[0059] Exemplarily, the tray assembly carries the battery 50 and moves in the first direction. The conveying assembly drives the battery 50 in the tray assembly to move in the first direction. When the battery 50 reaches the position where the battery gripping device is located, the conveying assembly stops conveying. At this time, the second driving member 334 in the battery gripping device drives the first driving member 302 to approach the battery in the third direction. The first moving member 304 and the second moving member 306 move away from each other in the first direction, increasing the distance between the first gripper 312 and the second gripper 314. When the second driving member 334 drives the first gripper 312 and the second gripper 314 to reach the battery, the second driving member 334 stops driving; the first moving member 304 and the second moving member 306 move towards each other in the first direction until the first gripper 312 and the second gripper 314 clamp the battery; the second driving member 334 drives the first driving member 302 to rise in the third direction, causing the battery to leave the tray assembly and be transported to a predetermined position; the second driving member 334 drives the first driving member 302 to descend in the third direction until the battery is placed stably. When the battery transfer is completed, the conveying assembly continues to drive the tray assembly to move in the first direction until the next battery to be transferred reaches the position where the battery gripping device is located.

[0060] In this embodiment, the battery gripping device and the conveying assembly in the battery conveying device cooperate, reducing the steps in the battery transfer process and avoiding the need to move the battery multiple times during conveying and transfer to adapt to the position of the battery gripping device. In addition, the tray assembly in the battery transfer device can adjust the size of the battery receiving groove, and thus can be applicable to batteries of different model sizes. The battery gripping device is connected to the first driving member and the gripping assembly through the adjustment assembly, increasing the adjustable range of the distance between the first gripper and the second gripper, and can also be applicable to batteries of different model sizes without the need to replace the battery gripping device correspondingly.

[0061] In some embodiments, the present invention provides a battery sorter, including the battery gripping device in any other embodiment or the battery conveying device in any other embodiment.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
