[0019] To facilitate understanding of the present disclosure, the present disclosure will now be described more comprehensively with reference to the accompanying drawings, in which preferred embodiments of the present disclosure are shown. However, the present disclosure is not limited to the embodiments set forth herein, but may be embodied in many different forms. On the contrary, the purpose of providing these embodiments is to provide a more complete understanding of the teachings of the present disclosure.

[0020] It should be noted that when an element is referred to as "anchored" to another element, it may be directly located on the other element, or intervening elements may be present. When an element is considered to be "connected" to another element, it may be directly connected to the other element, or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for purposes of description only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure pertains. Terms used in the specification of the present disclosure are for the purpose of describing particular embodiments and are not intended to limit the present disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0022] 1-3, one embodiment of the present disclosure is directed to a lifting and lowering device 10. The lifting and lowering device 10 includes a clip mechanism 10a and a clamping claw mechanism 10b.

[0023] The clip mechanism 10a includes a pallet 200 and a first restraint assembly 300 provided on the outer periphery of the pallet 200. The pallet 200 is used to place the material 20 on the pallet 200. The first restraint assembly 300 has a first restraint state and a first retracted state. In the first restraint state, the first restraint assembly 300 restrains the material 20 positioned on the pallet 200 on the pallet 200. That is, in the first restraint state, the first restraint assembly 300 does not interfere with lifting the material 20 from the pallet 200. In the first retracted state, the first restraint assembly 300 disengages from the material 20 and is positioned on the outer periphery of the material 20, thereby releasing the restraint of the material 20 by the first restraint assembly 300. That is, in the first retracted state, the first restraint assembly 300 does not interfere with lifting the material 20 from the pallet 200.

[0024] The clamp claw mechanism 10b includes a clamp claw assembly 400 and a second restraint assembly 500 provided on the clamp claw assembly 400. The clamp claw assembly 400 is used to lift and lower the material 20 onto the pallet 200. The clamp claw assembly 400 has a gripping state and a release state. In the gripping state, the clamp claw assembly 400 grips the material 20. In the release state, the clamp claw assembly 400 disengages from the material 20 and is positioned around the outer periphery of the material 20, releasing the clamp claw assembly 400 from its grip on the material 20. The second restraint assembly 500 has a second restraint state and a second retracted state. In the second restraint state, the second restraint assembly 500 restrains the material 20 positioned on the clamp claw assembly 400 to the clamp claw assembly 400. In the second retracted state, the second constraint assembly 500 disengages from the material 20, releasing the constraint placed on the material 20 by the second constraint assembly 500, and the clamp jaw assembly 400 can be switched from the gripping state to the release state. The first constraint assembly 300 can be in the first constrained state while the second constraint assembly 500 is in the second constrained state. In other words, the switching of the first constraint assembly 300 between the first constrained state and the first retracted state and the switching of the second constraint assembly 500 between the second constrained state and the second retracted state do not interfere with each other.

[0025] When using the above-mentioned lifting and lowering device 10 to lift the material 20, first, the material 20 is placed on the pallet 200, and the material 20 can be restrained on the pallet 200 by the first restraint assembly 300. Then, the clamp claw assembly 400 of the clamp claw mechanism 10b is controlled to grasp the material 20 on the pallet 200, and the material 20 located on the clamp claw assembly 400 can be restrained to the clamp claw assembly 400 by the second restraint assembly 500. At this time, the first restraint assembly 300 and the second restraint assembly 500 simultaneously restrain the material 20, and the first restraint assembly 300 can be controlled to switch from the first restrained state to the first retracted state. Finally, the clamp claw mechanism 10b lifts the material 20 restrained by the second restraint assembly 500, thereby completing the process of lifting the material 20.

[0026] When using the above-mentioned lifting and lowering device 10 to lift and lower the material 20, first, the material 20 is placed on the clamp jaw assembly 400 of the clamp jaw mechanism 10b, and the material 20 located on the clamp jaw assembly 400 can be restrained by the second restraint assembly 500 to the clamp jaw assembly 400; then, the material 20 in the clamp jaw assembly 400 can be placed on the pallet 200, and the material 20 can be restrained on the pallet 200 by the first restraint assembly 300; then, the second restraint assembly 500 can be controlled to switch from the second restraint state to the second retracted state; and finally, the clamp jaw assembly 400 can switch from the gripping state to the release state to complete the process of lifting and lowering the material 20.

[0027] During the process of lifting and lowering the material 20, the material 20 is always restrained by the first restraint assembly 300 and / or the second restraint assembly 500, i.e., during the process of lifting and lowering the material 20, the material 20 is always in a restrained state, thereby avoiding the problem of movement / shift between layers of the material 20 in the laminated structure due to the material 20 being in an unrestrained state, which affects the alignment between the layers of the material 20 and the success rate of subsequent detection devices, resulting in low production efficiency.

[0028] In this embodiment, material 20 is a battery cell. As can be appreciated, in other embodiments, material 20 may be other materials having a layered structure.

[0029] In this embodiment, the first restraint assembly 300 includes a first pressing part 310 and a second pressing part 320. The first pressing part 310 and the second pressing part 320 are respectively provided on both sides of the pallet 200 in the first direction. The first pressing part 310 and the second pressing part 320 are both reciprocating in the first direction and both reciprocating in the height direction so that the first restraint assembly 300 can switch between a first restrained state and a first retracted state. It should be noted that in this embodiment, the first pressing part 310 and the second pressing part 320 being both reciprocating in the first direction means that the first pressing part 310 can move toward or away from the pallet 200 in the first direction, and the second pressing part 320 can move toward or away from the pallet 200 in the first direction. The fact that both the first pressing part 310 and the second pressing part 320 are capable of reciprocating movement in the vertical direction means that the first pressing part 310 can move toward or away from the pallet 200 in the vertical direction, and the second pressing part 320 can move toward or away from the pallet 200 in the vertical direction.

[0030] The first pressing part 310 and the second pressing part 320 can be controlled to move in a first direction, and both the first pressing part 310 and the second pressing part 320 can be directed toward the pallet 200, so that the first pressing part 310 and the second pressing part 320 are above the pallet 200; the first pressing part 310 and the second pressing part 320 can be controlled to move in a height direction, and both the first pressing part 310 and the second pressing part 320 can be directed toward the pallet 200, so that the first pressing part 310 and the second pressing part 320 can press against the material 20 positioned on the pallet 200, thereby switching the first restraint assembly 300 from the first retracted state to the first restraint state.

[0031] The first pressing part 310 and the second pressing part 320 are controlled to move in a vertical direction, and both the first pressing part 310 and the second pressing part 320 are moved away from the pallet 200, so that the first pressing part 310 and the second pressing part 320 are separated from the material 20 on the pallet 200; the first pressing part 310 and the second pressing part 320 are moved in a first direction, and both the first pressing part 310 and the second pressing part 320 are moved away from the pallet 200, so that the first pressing part 310 and the second pressing part 320 are located at the outer periphery of the pallet 200, thereby switching the first restraint assembly 300 from the first restraint state to the first retracted state.

[0032] In this way, it is easy to realize that the first restraint assembly 300 has a first restraint state and a first retracted state. As can be understood, in other embodiments, when the clearance distance between the first pressing element 310 and the second pressing element 320 and the pallet 200 is the same as the thickness of the material 20, the first pressing element 310 and the second pressing element 320 do not need to be reciprocable in the height direction.

[0033] In this embodiment, the first restraint assembly 300 further includes a first horizontal cylinder 330, a second horizontal cylinder 340, a first height cylinder 350, and a second height cylinder 360. The first horizontal cylinder 330 and the second horizontal cylinder 340 are located on both sides of the pallet 200 in the first direction. The first height cylinder 350 and the second height cylinder 360 are provided on the first horizontal cylinder 330 and the second horizontal cylinder 340, respectively. The first pressing element 310 and the second pressing element 320 are provided on the first height cylinder 350 and the second height cylinder 360, respectively. The first horizontal cylinder 330 and the second horizontal cylinder 340 can drive the first pressing element 310 and the second pressing element 320, respectively, to reciprocate in the first direction. The first height cylinder 350 and the second height cylinder 360 can drive the first pressing element 310 and the second pressing element 320, respectively, to reciprocate in the height direction. The first horizontal cylinder 330 and the second horizontal cylinder 340 are disposed at the bottom, and the first height cylinder 350 and the second height cylinder 360 are disposed at the top, which is beneficial to the structural stability of the first restraint assembly 300. As can be appreciated, in other embodiments, the first height cylinder 350 and the second height cylinder 360 may be disposed at the bottom, and the first horizontal cylinder 330 and the second horizontal cylinder 340 may be disposed at the top, i.e., the first horizontal cylinder 330 and the second horizontal cylinder 340 may be disposed on the first height cylinder 350 and the second height cylinder 360, respectively, and the first pressing element 310 and the second pressing element 320 may be disposed on the first horizontal cylinder 330 and the second horizontal cylinder 340, respectively.

[0034] In this embodiment, the clamp claw assembly 400 includes a first clamp claw component 410 and a second clamp claw component 420. The first clamp claw component 410 and the second clamp claw component 420 are arranged at a distance from each other in the second direction. The first clamp claw component 410 and the second clamp claw component 420 are both reciprocatable in the second direction so that the clamp claw assembly 400 can switch between a gripping state and a separation state. The second constraint assembly 500 includes a third pressing component 510 and a fourth pressing component 520. The third pressing component 510 and the fourth pressing component 520 are provided on the first clamp claw component 410 and the second clamp claw component 420, respectively, and are both reciprocatable in the height direction so that the second constraint assembly 500 can switch between a second constraint state and a second retracted state.

[0035] The first clamping claw component 410 and the second clamping claw component 420 are controlled to move in a second direction, and the first clamping claw component 410 and the second clamping claw component 420 are directed toward the material 20, causing the first clamping claw component 410 and the second clamping claw component 420 to grip the material 20; the third pressing component 510 and the fourth pressing component 520 are controlled to move in a height direction, and the third pressing component 510 and the fourth pressing component 520 are directed toward the material 20, causing the third pressing component 510 and the fourth pressing component 520 to press the material 20 located on the first clamping claw component 410 and the second clamping claw component 420, respectively, thereby switching the second restraining assembly 500 from the second retracted state to the second restraining state.

[0036] The third pressing element 510 and the fourth pressing element 520 can be controlled to move in a height direction, causing the third pressing element 510 and the fourth pressing element 520 to move away from the material 20, thereby separating the third pressing element 510 and the fourth pressing element 520 from the material 20 located on the first clamping claw element 410 and the second clamping claw element 420, respectively, so that the second restraining assembly 500 switches from the second restraining state to the second retracted state. The first clamping claw element 410 and the second clamping claw element 420 can then be controlled to move in a second direction, causing the first clamping claw element 410 and the second clamping claw element 420 to move away from the material 20, thereby separating the first clamping claw element 410 and the second clamping claw element 420 from the material 20 and positioning them at the outer periphery of the material 20, at which point the third pressing element 510 and the fourth pressing element 520 are also positioned at the outer periphery of the material 20.

[0037] In this way, it is easy to realize that the second restraint assembly 500 has the second restraint state and the second retracted state. As can be understood, in other embodiments, when the gap distance between the third pressing component 510 and the first clamping claw component 410 is the same as the thickness of the material 20, and the gap distance between the fourth pressing component 520 and the second clamping claw component 420 is the same as the thickness of the material 20, the third pressing component 510 and the fourth pressing component 520 do not need to be reciprocable in the height direction.

[0038] In this embodiment, the first direction, the second direction, and the height direction are perpendicular to each other, i.e., a three-dimensional Cartesian coordinate system can be constructed. In this manner, it is easy to realize that the first constraint assembly 300 is in the first constraint state while the second constraint assembly 500 is in the second constraint state. As can be understood, in other embodiments, the first clamping claw component 410 and the second clamping claw component 420 can both reciprocate in the first direction so that the clamping claw assembly 400 can switch between the gripping state and the separation state. In this case, the entire assembly consisting of the first pressing component 310 and the second pressing component 320 can be arranged at a distance from the entire assembly consisting of the first clamping claw component 410 and the second clamping claw component 420 in the second direction.

[0039] In this embodiment, the second restraint assembly 500 further includes a third height cylinder 530 and a fourth height cylinder 540. The third height cylinder 530 and the fourth height cylinder 540 are respectively provided on the first clamping jaw component 410 and the second clamping jaw component 420. The third pressing component 510 and the fourth pressing component 520 are respectively provided on the third height cylinder 530 and the fourth height cylinder 540. The third height cylinder 530 and the fourth height cylinder 540 drive the third pressing component 510 and the fourth pressing component 520, respectively, to reciprocate in the height direction. In this manner, the second restraint assembly 500 can easily be realized to have a second restrained state and a second retracted state. As can be appreciated, in other embodiments, a structure such as a screw may be used instead of the third height cylinder 530 and the fourth height cylinder 540.

[0040] In this embodiment, the clamp claw assembly 400 further includes a first vertical plate 430 and a second vertical plate 440. The first vertical plate 430 and the second vertical plate 440 are both reciprocatable in the second direction. The third pressing element 510 is located between the first vertical plate 430 and the second vertical plate 440 and is attached to the first vertical plate 430. The first clamp claw element 410 is attached to the side of the first vertical plate 430 away from the third pressing element 510 so as to be movable in the height direction. The fourth pressing element 520 is located between the first vertical plate 430 and the second vertical plate 440 and is attached to the second vertical plate 440. The second clamp claw element 420 is attached to the side of the second vertical plate 440 away from the fourth pressing element 520 so as to be movable in the height direction. The first clamping claw element 410 and the second clamping claw element 420 are capable of floating in the height direction, which can buffer the clamping force of the second restraining assembly 500 on the material 20, avoid unbuffered pressure, and better protect the material 20. As can be appreciated, in other embodiments, the first clamping claw element 410 and the second clamping claw element 420 may not be capable of floating in the height direction, in which case a buffer layer may be provided at the end of the second restraining assembly 500 to avoid unbuffered pressure on the material 20.

[0041] In this embodiment, the clamp claw assembly 400 further includes a clamp claw cylinder 450. Both the first clamp claw component 410 and the second clamp claw component 420 are mounted on the clamp claw cylinder 450. The clamp claw cylinder 450 can drive the first clamp claw component 410 and the second clamp claw component 420 to open and close in the second direction. In this manner, it is easy to realize that both the first clamp claw component 410 and the second clamp claw component 420 can reciprocate in the second direction, and the structure of the clamp claw assembly 400 can be simplified. As can be appreciated, in other embodiments, two clamp claw cylinders, a first clamp claw cylinder connected to the first clamp claw component 410 and a second clamp claw cylinder connected to the second clamp claw component 420, can be provided, and the first clamp claw cylinder and the second clamp claw cylinder can drive the first clamp claw component 410 and the second clamp claw component 420, respectively, to reciprocate in the second direction.

[0042] In this embodiment, the clamping claw assembly 400 further includes a first connecting plate 460, a second connecting plate 470, a first vertical plate 430, a second vertical plate 440, a first floating plate 480, and a second floating plate 490. The first connecting plate 460 and the second connecting plate 470 are each connected to a clamping claw cylinder 450. The clamping claw cylinder 450 can drive the first connecting plate 460 and the second connecting plate 470 to move open and closed in a second direction. The first vertical plate 430 and the second vertical plate 440 are respectively provided on the first connecting plate 460 and the second connecting plate 470. The third pressing element 510 is located between the first vertical plate 430 and the second vertical plate 440 and is provided on the first vertical plate 430. The first clamping claw element 410 is provided on the side of the first vertical plate 430 away from the third pressing element 510 via the first floating plate 480 so as to be movable in the height direction. The fourth pressing component 520 is located between the first vertical plate 430 and the second vertical plate 440, and is provided on the second vertical plate 440. The second clamping claw component 420 is provided on the side of the second vertical plate 440 away from the fourth pressing component 510 via a second floating plate 490 so as to be able to float in the height direction. In this way, the structure of the clamping claw assembly 400 is easy to construct.

[0043] In this embodiment, the clamp claw mechanism 10b further includes a drive assembly. The clamp claw assembly 400 is mounted on the drive assembly, and the drive assembly can drive the clamp claw assembly 400 to reciprocate in the vertical direction. Specifically, in this embodiment, the clamp claw assembly 400 further includes a clamp claw back plate 400a. The clamp claw assembly 400 is connected to the drive assembly via the clamp claw back plate 400a. In this manner, the clamp claw assembly 400 can be easily moved toward or away from the clip mechanism 10a. As can be appreciated, in other embodiments, the drive assembly can be omitted if there is no need to adjust the vertical positions of the clamp claw assembly 400 and the clip mechanism 10a.
