They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0046] Please see Figure 1 and Figure 2 The battery cell clamping device 100 provided in the embodiments of this application will now be described. The battery cell clamping device 100 provided in the embodiments of this application includes a first driving mechanism 10 and two clamping mechanisms 20. The two clamping mechanisms 20 are arranged at intervals along a first direction.

[0047] Please see Figure 3 and Figure 4 The clamping mechanism 20 includes an adjustment component and two grippers 23. The first drive mechanism 10 can drive at least one adjustment component of the clamping mechanism 20 to move along a first direction, thereby bringing the two adjustment components closer together, that is, bringing the two grippers on the two adjustment components closer together, so as to clamp the battery cell 200 on opposite sides along the first direction.

[0048] Understandably, the first drive mechanism 10 can simultaneously drive the adjusting components of the two clamping mechanisms 20 to move closer to each other along the first direction, thereby clamping the battery cell 200 on opposite sides along the first direction. Alternatively, the adjusting components of the two clamping mechanisms 20 can be configured such that one is fixed and the other is movable along the first direction. The first drive mechanism 10 drives the adjusting component of one clamping mechanism 20 to move closer to the adjusting component of the other clamping mechanism 20 along the first direction, thereby achieving clamping of the battery cell 200 on opposite sides along the first direction.

[0049] When it is necessary to clamp the battery cell 200, the first drive mechanism 10 drives the adjustment component of at least one clamping mechanism 20 to move along a first direction, thereby clamping the battery cell 200 on opposite sides along the first direction. When it is necessary to release the battery cell 200, the first drive mechanism 10 drives at least one clamping mechanism 20 to move away from each other along the first direction, thereby releasing the battery cell 200.

[0050] Specifically, the first drive mechanism 10 can be a cylinder or an electric motor.

[0051] Two grippers 23 are spaced apart on the adjustment assembly along the second direction, and the opposite sides of the battery cell 200 along the second direction are located between the two grippers 23.

[0052] The adjustment component can be used to adjust the displacement of the gripper 23 along the first direction, that is, to adjust the distance between the grippers 23 of the two clamping mechanisms 20 along the first direction.

[0053] The first direction is the same as the length direction of the battery cell 200, and the second direction is the same as the width direction of the battery cell 200. The first and second directions are set at an angle. Specifically, the first and second directions can be set at 90°. Please refer to [link / reference]. Figure 1 and Figure 2 The "first direction" can be represented by the X-axis, the "second direction" can be represented by the Y-axis, and the "third direction" below can be represented by the Z-axis.

[0054] The working principle of the battery cell clamping device 100 in this embodiment is as follows:

[0055] When it is necessary to clamp the battery cell 200, the first drive mechanism 10 first drives the adjustment component of at least one clamping mechanism 20 to move along the first direction, so that the two adjustment components can be brought closer together, that is, the two jaws on the two adjustment components are brought closer to each other, so that the battery cell 200 can be clamped on opposite sides along the first direction.

[0056] When the length of the battery cell 200 is inconsistent, the displacement of the gripper 23 along the first direction can be adjusted by adjusting the component. The distance between the grippers 23 of the two clamping mechanisms 20 along the first direction can be adjusted according to the length of the battery cell 200, so that it can be used to clamp battery cells 200 of different lengths.

[0057] The battery cell clamping device 100 provided in this application embodiment includes a first driving mechanism 10 and two clamping mechanisms 20 spaced apart along a first direction. The first driving mechanism 10 drives at least one clamping mechanism 20 to move along the first direction to clamp the battery cell 200 on opposite sides along the first direction. The clamping mechanism 20 includes an adjustment component and two grippers 23. The displacement of the grippers 23 along the first direction can be adjusted by the adjustment component. The distance between the grippers 23 of the two clamping mechanisms 20 along the first direction can be adjusted according to the length of the battery cell 200, so that it can be applied to clamping battery cells 200 of different lengths and has higher compatibility.

[0058] Please see Figure 3 and Figure 4 The adjustment assembly may include a mounting base 21, an adjustment base 22, and a first adjustment member. The mounting base 21 may have multiple first connecting holes 211 spaced apart along a first direction. The adjustment base 22 may have a first through hole 221. The first adjustment member (not shown) passes through the first through hole 221 and connects to any of the first connecting holes 211. Two grippers are spaced apart on the adjustment base along a second direction. When it is necessary to adjust the position of the adjustment base 22 along the first direction, the first adjustment member is first released from the first connecting hole 211. At this time, the adjustment base 22 can move relative to the mounting base 21 along the first direction. When the adjustment base 22 moves to a preset position, the first adjustment member passes through the first through hole 221 and connects to the first connecting hole 211 at the preset position. The adjustment is very simple and convenient. Specifically, the first adjustment member can be a screw, and the first connecting hole 211 can be a threaded hole. The position of the adjusting seat 22 can be adjusted according to the length of the battery cell 200, thereby adjusting the distance between the jaws of the two clamping mechanisms 20 along the first direction, thus making it suitable for clamping battery cells 200 of different lengths.

[0059] Please see Figure 3 and Figure 4The mounting base 21 may be provided with a retaining edge 212 extending in the first direction, and the adjusting base 22 is provided with a retaining groove 223 that is adapted to the retaining edge 212. Through the cooperation between the retaining groove 223 and the retaining edge 212, the adjusting base 22 is prevented from falling off the mounting base 21 and plays a guiding role to ensure the motion accuracy.

[0060] Please see Figure 3 and Figure 4 The adjusting seat 22 may include a connector 224 and a slider 225, with a first through hole formed on the connector 224. The slider 225 is movably disposed on the connector 224 along a third direction, and two grippers 23 are spaced apart on the slider 225 along a second direction.

[0061] The clamping mechanism 20 may also include an elastic buffer assembly 25. One end of the elastic buffer assembly 25 is connected to the connector 224, and the other end is connected to the slider 225.

[0062] The third direction is set at an angle to the second and first directions, specifically, the third direction is set at 90° to both the second and first directions. When the gripper 23 collides with the battery cell 200, the gripper 23 can overcome the elastic force of the elastic buffer component 25 and retract along the third direction, thereby avoiding a hard collision between the gripper 23 and the battery cell 200 and preventing damage to the gripper 23 and the battery cell 200.

[0063] Please see Figure 3 and Figure 4 The clamping mechanism 20 may further include a first guide rail 26 and a first slider 27 slidably mounted on the first guide rail 26. The first guide rail 26 is disposed on the adjusting seat 22, and the first slider 27 is connected to the slider 225. Through the cooperation of the first guide rail 26 and the first slider 27, a limiting and guiding function can be achieved to prevent the slider 225 from shifting when moving in a third direction, thereby further improving the positioning accuracy.

[0064] It is understood that the two grippers 23 are spaced apart along the second direction on the adjustment assembly to form a limiting groove 231 that is adapted to the width of the battery cell 200, that is, the size of the limiting groove 231 is adapted to the width of the battery cell 200.

[0065] Please see Figure 3 and Figure 4 The clamping mechanism 20 may further include a second drive mechanism 24, which is tractively connected to at least one gripper 23 to drive the gripper 23 to move along a second direction. By driving at least one gripper 23 to move along the second direction through the second drive mechanism 24, the distance between the two grippers 23 along the second direction can be adjusted, thereby making it suitable for battery cells 200 of different widths.

[0066] Please see Figure 3 and Figure 4 The second drive mechanism 24 may include an adjusting screw disposed on an adjusting assembly. The adjusting screw is threadedly connected to at least one gripper 23 so that when the adjusting screw is rotated, the gripper 23 moves in a second direction. That is, by rotating the adjusting screw, the gripper 23 moves in the second direction, thereby adjusting the distance between the two grippers 23 in the second direction, thus making it suitable for battery cells 200 of different widths.

[0067] Please see Figure 3 and Figure 4 The clamping mechanism 20 may further include a locking element (not shown in the figure). At least one gripper 23 has a through groove 232, and the adjusting component has a locking hole 222. When the gripper 23 moves to a preset position in the second direction, the locking element passes through the through groove 232 and connects to the locking hole 222. The locking element ensures that the gripper 23 is locked in place after adjustment, preventing displacement. When it is necessary to adjust the position of the gripper 23 in the second direction, the locking element must first be loosened. At this time, the position of the gripper 23 in the second direction can be adjusted using the adjusting screw.

[0068] Of course, the second drive mechanism 24 is not limited to this configuration. For example, the second drive mechanism 24 may also include a motor or a cylinder, which can also drive the gripper 23 to move in the second direction.

[0069] The arrangement of "at least one of the two grippers 23 is movably and adjustably disposed on the adjustment assembly in the second direction" is not limited to this. For example, the adjustment assembly may also have a plurality of second connecting holes (not shown in the figure) spaced apart in the second direction, at least one gripper 23 has a second through hole (not shown in the figure), and the second adjustment member (not shown in the figure) passes through the second through hole and is connected to any second connecting hole.

[0070] When it is necessary to adjust the distance between the two grippers 23 along the second direction, firstly, the second adjusting member is loosened from the second connecting hole. At this time, the grippers 23 can move relative to the adjusting seat 22 along the second direction. When the grippers 23 move to the preset position, the second adjusting member passes through the second through hole and connects with the second connecting hole at the preset position. The adjustment is very simple and convenient. Specifically, the second adjusting member can be a screw, and the second connecting hole can be a threaded hole.

[0071] In this configuration, at least one of the two grippers 23 is movably and adjustably mounted on the adjustment assembly along a second direction. It is understood that by simply moving at least one of the two grippers 23 along the second direction, the distance between the two grippers 23 along the second direction can be adjusted, thus accommodating battery cells 200 of different widths. That is, one of the two grippers 23 can be a fixed gripper 23, and the other can be a movable gripper 23; simply moving the movable gripper 23 along the second direction achieves the adjustment of the distance between the two grippers 23 along the second direction. It is understood that the arrangement of the two grippers 23 is not limited to this. For example, in other embodiments, both grippers 23 can be configured to be movable along the second direction, which also achieves the adjustment of the distance between the two grippers 23 along the second direction.

[0072] Please see Figure 5 The gripper 23 may include an abutment block 233 and a limiting block 234. The abutment block 233 is disposed on the adjustment assembly and is used to abut against the side end of the battery cell 200 along the first direction. The limiting block 234 is connected to the abutment block 233, and the limiting blocks 234 of the two grippers 23 are used to accommodate the two sides of the battery cell 200 along the second direction.

[0073] Please see Figure 5 The gripper 23 may be provided with an anti-detachment protrusion 235. The anti-detachment protrusion can be movably locked onto the adjustment component in the second direction. Through the cooperation between the anti-detachment protrusion 235 and the adjustment component, the gripper 23 is prevented from falling off the adjustment component and plays a guiding role to ensure motion accuracy.

[0074] Please see Figure 1 and Figure 2 The battery cell clamping device 100 may further include a base 30, on which the first drive mechanism 10 is disposed. The battery cell clamping device 100 may also include a second guide rail 40 and a second slider 50 slidably mounted on the second guide rail 40. The second guide rail 40 is disposed on the base 30, and the second slider 50 is connected to the mounting base 21. The cooperation between the second guide rail 40 and the second slider 50 serves a limiting and guiding function, preventing the mounting base 21 from shifting when moving along the first direction, thereby further improving positioning accuracy.

[0075] Please see Figure 6 This application also provides a battery cell handling module, including a mounting frame 300, a first movable frame 400, a second movable frame 500, and a battery cell clamping device 100 as described in any of the above embodiments. The first movable frame 400 is movably disposed on the mounting frame 300 along a first direction or a second direction. The second movable frame 500 is movably disposed on the first movable frame 400 along a third direction, and the battery cell clamping device 100 is disposed on the second movable frame 500.

[0076] The battery cell handling module of this application includes the battery cell clamping device 100 in any of the above embodiments, and therefore has the beneficial effects brought by the battery cell clamping device 100 in any of the above embodiments, which will not be repeated here.

[0077] When it is necessary to move the battery cell 200, the first movable frame 400 is moved relative to the mounting frame 300 in the first or second direction, which allows the battery cell clamping device 100 to move to the position of the battery cell 200, and the second movable frame 500 is moved in the third direction, so that the battery cell clamping device 100 is close to the battery cell 200, and then the battery cell 200 is clamped by the battery cell clamping device 100.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
