Mode for Carrying Out the Invention

[0019] To facilitate understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the related drawings. The drawings show preferred embodiments of the present disclosure. However, the present disclosure is not limited to the embodiments described herein and can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to more completely understand the disclosure content of the present disclosure.

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

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art belonging to the technical field of the present disclosure. The terms used in the specification of the present disclosure are for the purpose of explaining specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] As shown in FIGS. 1-3, there is a lifting and lowering device 10 according to an embodiment of the present disclosure. The lifting and lowering device 10 includes a clip mechanism 10a and a clamp jaw 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 material 20 on it. The first restraint assembly 300 has a first restrained state and a first retracted state. In the first restrained state, the first restraint assembly 300 restrains the material 20 located on the pallet 200 to the pallet 200. That is, in the first restrained 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 detaches from the material 20 and is located on the outer periphery of the material 20, releasing the restraint on 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 clamping claw mechanism 10b includes a clamping claw assembly 400 and a second restraining assembly 500 provided on the clamping claw assembly 400. The clamping claw assembly 400 is used to lift and lower the material 20 onto the pallet 200. The clamping claw assembly 400 has a gripping state and a detached state. In the gripping state, the clamping claw assembly 400 grips the material 20. In the detached state, the clamping claw assembly 400 detaches from the material 20 and is located on the outer circumference of the material 20, releasing the grip on the material 20 by the clamping claw assembly 400. The second restraining assembly 500 has a second restraining state and a second retracted state. In the second restraining state, the second restraining assembly 500 restrains the material 20 located on the clamping claw assembly 400 to the clamping claw assembly 400. In the second retracted state, the second restraint assembly 500 detaches from the material 20, releasing the restraint on the material 20 by the second restraint assembly 500, and switching the clamp claw assembly 400 from a gripping state to a detached state. The first restraint assembly 300 can be in the first restrained state, and the second restraint assembly 500 can be in the second restrained state at the same time. That is, the switching between the first restraint state and the first retracted state of the first restraint assembly 300 and the switching between the second restraint state and the second retracted state of the second restraint assembly 500 do not interfere with each other.

[0025] When lifting the material 20 using the lifting and lowering device 10 described above, first, the material 20 is placed on the pallet 200 and the material 20 can be restrained on the pallet 200 by the first restraining assembly 300, the clamp claw assembly 400 of the clamp claw mechanism 10b is controlled to grip 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 restraining assembly 500, at which point the first restraining assembly 300 and the second restraining assembly 500 simultaneously restrain the material 20 and the first restraining assembly 300 can be controlled to switch from the first restrained state to the first retracted state, and finally, the clamp claw mechanism 10b can lift the material 20 restrained by the second restraining assembly 500 and complete the process of lifting the material 20.

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

[0027] During the process of lifting and lowering the material 20, the material 20 is always constrained by the first constraining assembly 300 and / or the second constraining assembly 500. That is, during the process of lifting and lowering the material 20, the material 20 is always in a constrained state. This avoids the problem of low production efficiency, as the unconstrained state of the material 20 causes movement / displacement between layers of the laminated structure, which affects the alignment of the layers of the material 20 and the accuracy of the subsequent detection device.

[0028] In this embodiment, material 20 is a battery cell. To understand this, 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 component 310 and a second pressing component 320. The first pressing component 310 and the second pressing component 320 are provided on both sides of the pallet 200 in a first direction, respectively. Both the first pressing component 310 and the second pressing component 320 are reciprocable in a first direction and are also reciprocable 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 fact that both the first pressing component 310 and the second pressing component 320 are reciprocable in a first direction means that the first pressing component 310 can move toward or away from the pallet 200 in a first direction, and the second pressing component 320 can move toward or away from the pallet 200 in a first direction. The fact that both the first pressing component 310 and the second pressing component 320 are capable of reciprocating motion in the height direction means that the first pressing component 310 can move toward or away from the pallet 200 in the height direction, and the second pressing component 320 can move toward or away from the pallet 200 in the height direction.

[0030] The first pressing component 310 and the second pressing component 320 can be controlled to move in a first direction, and both the first pressing component 310 and the second pressing component 320 can be directed toward the pallet 200, and the first pressing component 310 and the second pressing component 320 can be directed toward the pallet 200, and each of the first pressing component 310 and the second pressing component 320 can be pressed toward the material 20 located on the pallet 200, thereby enabling the first restraint assembly 300 to be switched from a first retracted state to a first restrained state.

[0031] The first pressing component 310 and the second pressing component 320 are controlled to move in the height direction, and both the first pressing component 310 and the second pressing component 320 are moved away from the pallet 200, thereby separating the first pressing component 310 and the second pressing component 320 from the material 20 on the pallet 200. The first pressing component 310 and the second pressing component 320 are moved in a first direction, and both the first pressing component 310 and the second pressing component 320 are moved away from the pallet 200, so that the first pressing component 310 and the second pressing component 320 are on the outer circumference of the pallet 200, thereby enabling the first restraint assembly 300 to be switched from a first restrained state to a first retracted state.

[0032] In this way, it can be easily realized that the first restraint assembly 300 has a first restrained state and a first retracted state. As can be understood, in other embodiments, when the distance between the first pressing part 310 and the second pressing part 320 and the pallet 200 is the same as the thickness of the material 20, the first pressing part 310 and the second pressing part 320 do not need to be able to reciprocate 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 either side of the pallet 200 in a first direction, respectively. 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 component 310 and the second pressing component 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 component 310 and the second pressing component 320 to reciprocate in a first direction, respectively. The first height cylinder 350 and the second height cylinder 360 can drive the first pressing component 310 and the second pressing component 320 to reciprocate in the height direction, respectively. The first horizontal cylinder 330 and the second horizontal cylinder 340 are located below, and the first height cylinder 350 and the second height cylinder 360 are located above, thereby providing greater structural stability to the first restraint assembly 300. To make it clear, in other embodiments, the first height cylinder 350 and the second height cylinder 360 may be located below, and the first horizontal cylinder 330 and the second horizontal cylinder 340 may be located above, that is, the first horizontal cylinder 330 and the second horizontal cylinder 340 may be located on the first height cylinder 350 and the second height cylinder 360 respectively, and the first pressing component 310 and the second pressing component 320 may be located on the first horizontal cylinder 330 and the second horizontal cylinder 340 respectively.

[0034] In this embodiment, the clamping claw assembly 400 includes a first clamping claw component 410 and a second clamping claw component 420. The first clamping claw component 410 and the second clamping claw component 420 are spaced apart in a second direction. Both the first clamping claw component 410 and the second clamping claw component 420 are reciprocating in the second direction so that the clamping claw assembly 400 can switch between a gripping state and a release state. The second restraining 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 clamping claw component 410 and the second clamping claw component 420, respectively, and are reciprocating in the height direction so that the second restraining assembly 500 can switch between a second restraining 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, allowing 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 the height direction, and the third pressing component 510 and the fourth pressing component 520 are directed toward the material 20, allowing the third pressing component 510 and the fourth pressing component 520 to press against the material 20 located on the first clamping claw component 410 and the second clamping claw component 420, respectively, thereby enabling the second restraint assembly 500 to switch from a second retracted state to a second restrained state.

[0036] The third pressing part 510 and the fourth pressing part 520 are controlled to move in the height direction, and the third pressing part 510 and the fourth pressing part 520 are moved away from the material 20, and the third pressing part 510 and the fourth pressing part 520 are separated from the material 20 where the first clamping claw part 410 and the second clamping claw part 420 are located, thereby enabling the second restraint assembly 500 to switch from the second restraint state to the second retraction state, and the first clamping claw part 410 and the second clamping claw part 420 are controlled to move in the second direction, and the first clamping claw part 410 and the second clamping claw part 420 are moved away from the material 20, and the first clamping claw part 410 and the second clamping claw part 420 are separated from the material 20 and can be located on the outer circumference of the material 20, at which time the third pressing part 510 and the fourth pressing part 520 are also located on the outer circumference of the material 20.

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

[0038] In this embodiment, the first direction, the second direction, and the height direction are perpendicular to each other in pairs, that is, a three-dimensional rectangular coordinate system can be constructed. In this way, it is easy to realize that the first constraint assembly 300 is in the first constraint state and the second constraint assembly 500 is in the second constraint state at the same time. To make it clear, in other embodiments, the first clamp claw component 410 and the second clamp claw component 420 are both reciprocating in the first direction so that the clamp claw assembly 400 can switch between a gripping state and a release state, and in this case, the whole consisting of the first pressing component 310 and the second pressing component 320 can be arranged with a gap in the second direction from the whole consisting of the first clamp claw component 410 and the second clamp claw component 420.

[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 provided on the first clamping claw component 410 and the second clamping claw component 420, respectively. The third pressing component 510 and the fourth pressing component 520 are provided on the third height cylinder 530 and the fourth height cylinder 540, respectively. 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 way, the second restraint assembly 500 can easily achieve a second restrained state and a second retracted state. To make it understandable, in other embodiments, a configuration such as screws may be used instead of the third height cylinder 530 and the fourth height cylinder 540.

[0040] In this embodiment, the clamping claw assembly 400 further includes a first vertical plate 430 and a second vertical plate 440. Both the first vertical plate 430 and the second vertical plate 440 are reciprocating in a second direction. A third pressing component 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 component 410 is provided so as to float in the height direction on the side of the first vertical plate 430 away from the third pressing component 510. A 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. A second clamping claw component 420 is provided so as to float on the side of the second vertical plate 440 away from the fourth pressing component 520. The first clamping claw component 410 and the second clamping claw component 420 are movable in the height direction, which can buffer the restraining force on the material 20 by the second restraining assembly 500, avoid unbuffered pressing, and better protect the material 20. To make it clear, in other embodiments, the first clamping claw component 410 and the second clamping claw component 420 do not have to be movable 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 pressing 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 a second direction. In this way, it is easier to realize that both the first clamp claw component 410 and the second clamp claw component 420 can reciprocate in a second direction, and the structure of the clamp claw assembly 400 can be simplified. To understand this, in other embodiments, there may be 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, and the first and second clamp claw cylinders can drive the first and second clamp claw components 410 and 420, respectively, to reciprocate in a second direction.

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

[0043] In this embodiment, the clamping claw mechanism 10b further includes a drive assembly. The clamping claw assembly 400 is provided on the drive assembly, and the drive assembly can drive the clamping claw assembly 400 to reciprocate in the height direction. Specifically, in this embodiment, the clamping claw assembly 400 further includes a clamping claw back plate 400a. The clamping claw assembly 400 is connected to the drive assembly via the clamping claw back plate 400a. In this way, the clamping claw assembly 400 can easily move closer to or away from the clipping mechanism 10a. As can be understood, in other embodiments, the drive assembly can be omitted when it is not necessary to adjust the height position of the clamping claw assembly 400 and the clipping mechanism 10a.

[0044] Specifically, in this embodiment, when lifting the material 20 using the lifting and lowering device 10, before the clamp claw assembly 400 of the clamp claw mechanism 10b grips the material 20 on the pallet 200, the drive assembly controls the first clamp claw component 410 and the second clamp claw component 420 to move downward in the height direction toward the material 20 until the upper surfaces of the first clamp claw component 410 and the second clamp claw component 420 are at least 2 mm away from the lower surface of the material 20, and controls the first clamp claw component 410 and the second clamp claw component 420 to move in a second direction, and directs the first clamp claw component 410 and the second clamp claw component 420 toward the material 20, causing the first clamp claw component 410 and the second clamp claw component 420 to grip the material 20, and the drive assembly can control the first clamp claw component 410 and the second clamp claw component 420 to move upward in the height direction to grip the material 20.

[0045] In this embodiment, as shown in Figure 2, the first pressing component 310, the first horizontal cylinder 330, and the first height cylinder 350 constitute the first restraint module, and the second pressing component 320, the second horizontal cylinder 340, and the second height cylinder 360 constitute the second restraint module. In this embodiment, there is one of each for the first and second restraint modules. To make it clear, in other embodiments, there may be multiple first restraint modules, which are spaced apart along the second direction, and there may be multiple second restraint modules, which are spaced apart along the second direction.

[0046] In this embodiment, as shown in Figures 1 and 3, both the first clamping claw component 410 and the second clamping claw component 420 have two clamping claw portions 412 that are spaced apart in the first direction. In this way, the material 20 can be gripped better. To understand that in other embodiments, the clamping claw assembly 400 may include a plurality of first clamping claw components 410 located on one side of the material 20 in the second direction and spaced apart along the first direction, and a plurality of second clamping claw components 420 located on the other side of the material 20 in the second direction and spaced apart along the first direction. To understand that in other embodiments, the first clamping claw component 410 and the second clamping claw component 420 may have only one clamping claw portion 412.
