[0046] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.

[0047] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. When used in this specification, the terms “comprising,” “including,” and / or “containing” mean that the associated integers, steps, operations, elements, and / or components are present, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or that other features, integers, steps, operations, elements, components, and / or groups may be added to the system / method.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0049] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0050] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0051] Considering the following description, these and other features of this specification, as well as the operation and function of the related components of the structure, and the economy of assembly and manufacture of the parts, can be significantly improved. All of these form part of this specification with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0052] The turret structure can move at high speed through the cooperation of the cam and the guide structure, which greatly improves the battery manufacturing efficiency. Welding is an important step in the battery manufacturing process. During the welding process, the workpieces to be welded (such as current collectors, top covers, etc.) are welded to the corresponding positions of the battery cell while the cell is fixed.

[0053] In existing technologies, battery cells are often fixed by clamping with grippers and the clamping power is provided by a cylinder. However, the cylinder gripper structure occupies a lot of space, which makes the diameter of the turret larger.

[0054] The present invention provides a clamping assembly that achieves clamping and releasing of the grippers by driving the horizontal movement of the gripper assembly, without requiring an additional power source, and reducing the size of the clamping assembly without affecting the clamping effect.

[0055] To achieve the above effects, this utility model embodiment provides a clamping component, such as... Figures 1-3 As shown, it includes a first motion component 1, a first gripper 21, an elastic element group 3, and a second motion component 4. The elastic element group 3 abuts against the first gripper 21 and the first motion component 1. The movement of the second motion component 4 drives the first gripper 21 to move, thereby compressing the first elastic element 31. The first elastic element 31 provides the first gripper 21 with a spring force for rapid reset.

[0056] like Figure 1-10 As shown, the following description uses a gripper assembly 2 with a pair of grippers as an example. The gripper assembly 2 includes a first gripper 21 and a second gripper 22. The first gripper 21 and the second gripper 22 can move closer or further apart to achieve gripping or releasing actions. The elastic element group 3 includes a first elastic element 31 and a second elastic element 32. The first elastic element 31 connects the first gripper 21 and the first motion assembly 1, and the second elastic element 32 connects the second gripper 22 and the first motion assembly 1. The second motion assembly 4 is connected to the gripper assembly 2 and drives the gripper assembly 2 to move. When the second motion assembly 4 moves in the first direction, the elastic element group 3 is compressed. When the second motion assembly 4 moves in the opposite direction of the first direction, the elastic element group 3 is released.

[0057] Specifically, the second motion component 4 causes the first gripper 21 to have a first position and a second position during movement, and the second gripper 22 to have a third position and a fourth position during movement. The first gripper 21 moves from the first position to the second position, compressing the first elastic element 31, and the second gripper 22 moves from the third position to the fourth position, compressing the second elastic element 32. When the first gripper 21 and the second gripper 22 return, the first elastic element 31 and the second elastic element 32 release their elastic force, causing the first gripper 21 and the second gripper 22 to quickly return to the first position and the third position, respectively.

[0058] It should be noted that the workpiece can be clamped or released using only the first gripper 21. For example, a robot arm can be set on the first gripper 21 to position the workpiece, or the second gripper 22 can be set as a fixed part adapted to the shape of the workpiece. The above purpose can also be achieved by only moving the first gripper 21.

[0059] It should be noted that, in order to achieve the relative movement between the first gripper 21 and the second gripper 22 driven by the movement of the second motion component 4, the movement direction of the first gripper 21 and the second gripper 22 is set to be oblique to the first direction. Thus, while the second motion component 4 moves along the first direction, driving the first gripper 21 and the second gripper 22 to move along the first direction, there is also relative movement between the two grippers. The aforementioned first direction can be arbitrarily set. To compress the elastic element group 3 when the second motion component 4 moves, the first direction also has a component representing the compression direction of the elastic element group 3. Since the workpiece is often lifted or transferred to the next station after clamping, the first direction can also be set to a horizontal or vertical direction.

[0060] There are multiple preset movement paths for the first gripper 21 and the second gripper 22. For example, a first conversion element and a second conversion element can be provided. The first conversion element has a first guide surface on the side facing the second conversion element, and the second conversion element has a second guide surface on the side facing the first conversion element. Both the first and second guide surfaces are inclined, and the distance between the first and second guide surfaces gradually decreases from bottom to top. When the second motion component 4 rises, under the guidance of the first and second guide surfaces, the first gripper 21 and the second gripper 22 gradually approach each other. When the second motion component 4 rises until the workpiece reaches the predetermined position, the first gripper 21 and the second gripper 22 clamp the workpiece together. Similarly, when the second motion component 4 descends, the first gripper 21 and the second gripper 22 move away from each other and are released.

[0061] like Figure 3 , Figure 4 and Figure 5As shown, the first motion component 1 includes a track plate 11, on which a first track 120 and a second track 121 are formed, and the distance between the first track 120 and the second track 121 gradually decreases from bottom to top. The first track 120 and the second track 121 are track groove structures. The first gripper 21 has a first roller 211, which slides within the first track 120; the second gripper 22 has a second roller 221, which slides within the second track 121. When the second motion component 4 rises, the first roller 211 slides within the first track 120, and the groove wall of the first track 120 is supported by the first roller 211. The second roller 221 slides within the second track 121, and the groove wall of the second track 121 is supported by the second roller 221. Driven by the first roller 211 and the second roller 221, the first gripper 21 and the second gripper 22 approach each other in the horizontal direction. When the second motion component 4 rises to the predetermined position of the workpiece, the first gripper 21 and the second gripper 22 clamp the workpiece together. Similarly, when the second motion component 4 descends, the first gripper 21 and the second gripper 22 move away from each other and are released.

[0062] like Figure 6 As shown, the first gripper 21 has a first position P1 and a second position P2 on the first track 120, and the second gripper 22 has a third position P3 and a fourth position P4 on the first track 120. The first gripper 21 moves from the first position P1 to the second position P2, compressing the first elastic element 31. The second gripper 22 moves from the third position P3 to the fourth position P4, compressing the second elastic element 32. When the first gripper 21 and the second gripper 22 return, the first elastic element 31 and the second elastic element 32 release their elastic force, causing the first gripper 21 and the second gripper 22 to quickly return to the first position P1 and the third position P3, respectively.

[0063] like Figure 7 and Figure 8 As shown, in order to facilitate the relative movement of the first gripper 21 and the second gripper 22, a gripper fixing seat 24 is also provided. The track plate 11 is also provided with a third track 122. The gripper fixing seat 24 is located on the third track 122. The gripper fixing seat 24 connects the first gripper 21, the second gripper 22 and the second motion component 4. The second motion component 4 drives the gripper fixing seat 24 to move downward, thereby driving the first gripper 21 and the second gripper 22 to move downward. The gripper fixing seat 24 can separate the first gripper 21 and the second gripper 22.

[0064] The first motion component 1 can be fixed to connect the gripper assembly 2 and the elastic element group 3, so that the elastic element group 3 can be compressed or released when the second motion component 4 drives the gripper assembly 2 to move up and down. For example, a first protrusion 130 and a second protrusion 131 are provided on the track plate 11. One end of the first elastic element 31 abuts against the first protrusion 130, and the other end abuts against the first gripper 21. One end of the second elastic element 32 abuts against the second protrusion 131, and the other end abuts against the second gripper 22.

[0065] Understandably, during the compression of the elastic component assembly 3, the second motion component 4 and the gripper assembly 2 move relative to the first motion component 1. In another embodiment of this invention, the first motion component 1 remains fixed, which can be achieved through bolts, pins, welding, or other methods. For example, as... Figure 2 and Figure 3 As shown, the clamping assembly 100 also includes a base plate 5 and a fixing seat 51. The track plate 11 is disposed on the fixing seat 51, and the base plate 5 is provided with a first guide rail 52. The track plate 11 and the fixing seat 51 slide on the first guide rail 52.

[0066] It should be noted that there are multiple ways to slide as described above. For example, the fixed seat 51 can be suspended on the first guide rail 52 using technologies such as magnetic levitation or airflow levitation, and can be driven to move along the first guide rail 52 by a driving component. Alternatively, the fixed seat 51 can be connected to the first guide rail 52 via ball bearings, and can be driven to slide along the first guide rail 52 by a driving component. Or, as... Figure 3 As shown, the fixed base 51 can directly contact the surface of the first guide rail 52, and the fixed base 51 is driven to slide along the first guide rail 52 by the second motion component 4.

[0067] The base plate 5 described above is also provided with a limiting member 53. The limiting member 53 is located on the movement path of the fixed base 51 and can abut against the fixed block 111 provided on the track plate 11 to limit the downward movement of the track plate 11. By providing the limiting member 53, the track plate 11 can remain stationary when the gripper assembly 2 and the second movement assembly 4 move downward, so as to facilitate the opening of the gripper assembly 2 and the compression of the elastic member assembly 3. It is understood that in another embodiment, a clamp can be provided to clamp the track plate 11 or screws can be used to fix the track plate 11, which is not limited here.

[0068] To ensure clamping accuracy and stability, a clamping limiter 23 is provided between the first clamping jaw 21 and the second clamping jaw 22. The clamping limiter 23 can be preset within a range of clamping force to ensure that the clamping jaws grip the object with appropriate force, avoiding excessive tightness or looseness. It also prevents damage to the first clamping jaw 21 and the second clamping jaw 22 from rapidly clamping or opening when the elastic element assembly 3 is released. Preferably, the clamping limiter 23 is connected to the clamping jaw fixing seat 24.

[0069] A pressure sensor 511 is provided on the fixed base 51, which can detect the real-time pressure value to prevent the gripper assembly 2 from being too tight or too loose. It can also cooperate with the gripper limiter 23 to control the gripping force.

[0070] There are various options for the elastic element, such as springs, elastic bands, retaining rings, and elastomers. To ensure the stability of the clamping assembly 100 and reduce its size, a spring is preferred as the elastic element. To improve the stability between the gripper assembly 2 and the elastic element group 3, the elastic element group 3 is set to a compressed state, thereby exerting downward pressure on the track plate 11, which allows the track plate 11 and the gripper assembly 2 to remain stable.

[0071] In addition, this utility model embodiment also provides a turret device, such as Figure 9 and Figure 10 As shown, the turret device includes the aforementioned clamping assembly 100, base 61, and turret (not shown).

[0072] The turret device provided in this embodiment of the present invention, by employing the clamping component 100 described in the above embodiment, can reduce the size of the turret device without affecting the workpiece clamping effect.

[0073] The second motion component includes a cam 41, a support member 42, and a connecting member 43. The cam 41 is connected to the lower end of the second support member 42, and the connecting member 43 connects the support member 42 to the base 6. A gripper assembly 2 is provided on the base 6. When the welding turret is used in conjunction with the turret, the welding turret rotates as a whole around a certain drive shaft. The cam 41 contacts a pre-set guide structure inside the turret and moves along the guide structure, which guides the cam 41 to rise and fall. The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
