[0072] The present application provides a clamping device and a clamping apparatus, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0073] Reference Figure 1 to Figure 3 The clamping device provided in the present application has a first direction X and a second direction Z that are perpendicular to each other. The clamping device includes a mounting seat 1, a clamping assembly 2 and a clamping assembly 3. The mounting seat 1 is used to install and carry the remaining components in the clamping device. The clamping assembly 2 includes a first driving member 21 and two clamping jaw structures 22. The two clamping jaw structures 22 are arranged opposite to each other along the first direction X to form a clamping space for clamping the battery cell 100. The first driving member 21 is arranged on the mounting seat 1 and is connected to at least one clamping jaw structure 22 to drive the two clamping jaw structures 22 to move closer to or away from each other. The clamping assembly 3 includes a clamping member 31 and a first adjustment structure 32. The clamping member 31 has a clamping surface 311. The clamping surface 311 is used to cooperate with the clamping jaw structure 22 to clamp the battery cell 100 in the second direction Z. The first adjustment structure 32 is connected to the clamping member 31 to adjust the angle of the clamping surface 311 relative to the first adjustment structure 32 so that the clamping surface 311 fits the surface of the battery cell 100.

[0074] In this embodiment, the present application connects the clamping member 31 with the first adjustment structure 32 so as to adjust the clamping surface 311 of the clamping member 31 through the first adjustment structure 32, so that the clamping surface 311 has different postures, that is, the clamping surface 311 can be parallel to or at an angle with the horizontal reference plane, and thus can fit with the surface of the battery cell 100 in different postures. It can be understood that the clamping surface 311 fits with the surface of the battery cell 100, in other words, the clamping surface 311 is parallel to and completely in contact with the surface of the battery cell 100. In this way, it can effectively avoid the problem that the battery cell 100 is damaged due to the direct downward pressure of the clamping member 31 along the second direction Z, thereby increasing the safety risk of the battery cell 100.

[0075] Based on the above embodiment, the pressing member 31 is movably connected to the first adjustment structure 32, and the pressing surface 311 is automatically adjusted to fit the surface of the battery cell 100 as the pressing member 31 and the clamping claw structure 22 clamp the battery cell 100. The pressing surface 311 is adaptively adjusted following the action of clamping the battery cell 100, which is conducive to better ensuring the surface fit of the pressing surface battery cell.

[0076] Alternatively, the clamping device has a first direction X, a second direction Z and a third direction Y that are perpendicular to each other, and the first adjustment structure 32 includes a power source, which is connected to the clamping member to drive the clamping member to rotate around the first direction X or the third direction Y until the clamping surface 311 of the clamping member 31 is in contact with the surface of the battery cell 100.

[0077] Figure 4 yes Figure 2 See the enlarged view of part A in Figure 2 to Figure 4 In order to realize the active connection between the clamping member 31 and the first adjustment structure 32, the clamping member 31 includes a clamping block 312 and a rolling body 313. The clamping block 312 has a first surface 3121 and a second surface 3122 arranged opposite to each other along the second direction Z. The first surface 3121 is used to constitute a clamping surface 311. The rolling body 313 is connected to the second surface 3122. A groove 321 is provided on the side of the first adjustment structure 32 facing the clamping block 312. The rolling body 313 is rotatably connected to the groove 321. There is a gap 200 between the clamping block 312 and the first adjustment structure 32 in the second direction Z. The gap is used to provide a reserved space for the clamping block 312 to rotate relative to the first adjustment structure 32, so as to realize the rotatable connection between the rolling body 313 and the groove 321. In addition, the clamping member 31 and the first adjustment structure 32 in this embodiment have simple structures and are easy to realize. For example, the second surface 3122 of the pressing block 312 and the spherical rolling body 313 are connected via a rod-shaped structure, the size of which is smaller than the maximum diameter of the spherical rolling body 313. Correspondingly, the groove 321 includes a first groove portion that cooperates with the spherical rolling body 313, and a second groove portion that cooperates with the rod-shaped structure.

[0078] Continue to refer to Figure 2 and Figure 3 , the first adjustment structure 32 includes a coupling member 322 and two blocking members 323. Among them, the groove 321 is arranged on the side of the coupling member 322 facing the pressing block 312, and penetrates the coupling member 322 perpendicularly to the second direction Z, and the two blocking members 323 are respectively connected to the two ends of the groove 321. In other words, the groove 321 can penetrate the coupling member 322 along the first direction X or the third direction Y, and the accompanying drawings only show an embodiment in which the groove 321 penetrates the coupling member 322 along the third direction Y. During the specific installation, the spherical rolling body 313 is installed into the groove 321 from the end of the groove 321, and then the two ends of the groove 321 are blocked by the two blocking members 323 to prevent the spherical rolling body 313 from falling off from the groove 321.

[0079] In other embodiments of the present application, the clamping assembly 3 also includes a second adjustment structure 33, which is indirectly connected to the clamping piece 31 through the first adjustment structure 32, and can adjust the position of the clamping piece 31 in the second direction Z, that is, the clamping piece 31 can achieve angle adjustment under the action of the first adjustment structure 32, and can achieve vertical movement under the action of the second adjustment structure 33, thereby increasing the application range of the clamping piece 31, that is, it can clamp battery cells 100 of different thicknesses.

[0080] The second adjustment structure 33 includes a fixing member 331 and a bolt 332. The fixing member 331 is connected to the clamping structure 22. The bolt 332 extends along the second direction Z and is penetrated by the fixing member 331. The bolt 332 is threadedly connected to the first adjustment structure 32, so that the height of the pressing member 31 can be adjusted through the first adjustment structure 32 by adjusting the depth of the bolt 332 screwed into the first adjustment structure 32.

[0081] Continue to refer to Figure 2 The fixing member 331 is provided with a guide portion 3311 extending along the second direction Z, and the first adjustment structure 32 is provided with an adapter portion, which is slidably connected with the guide portion 3311 to provide a guide for the first adjustment structure 32 to move along the second direction Z. For example, one of the guide portion 3311 and the adapter portion is a guide groove, and the other is a guide protrusion protruding toward the guide groove, and the guide protrusion is slidably matched in the guide groove.

[0082] For example, the fixing member 331 includes a first plate portion 3312 extending along the second direction Z, and a second plate portion 3313 protruding from the first plate portion 3312, the second plate portion 3313 extending along the third direction Y, and a plurality of matching holes arranged at intervals along the third direction Y are provided on the fixing member 331, the bolt 332 can be slidably matched in any matching hole, and the second adjustment structure 33 also includes at least two nuts 333, if the second adjustment structure 33 includes two nuts 333, the two nuts 333 are respectively provided on the upper side of the second plate portion 3313 and the lower side of the second plate portion 3313, so as to realize the positioning of the bolt 332 and the fixing member 331 in the second direction Z. If the second adjustment structure 33 includes three nuts 333, the remaining nut 333 contacts the first adjustment structure 32, so as to realize the positioning of the first adjustment structure 32 and the bolt 332 in the second direction Z.

[0083] It should be noted that, for the embodiment including both the joint member 322 and the fixing member 331, the joint member 322 is roughly L-shaped, the portion of the joint member 322 extending along the second direction Z is used to be connected to the fixing member 331 through the bolt 332, and the lower surface of the portion of the joint member 322 extending along the first direction X is provided with a groove 321. In addition, the portion of the joint member 322 extending along the second direction Z is provided with a notch 324, which is a scale line. At the same time, the fixing member 331 is provided with a reference member, which extends along the first direction X, and the height of the joint member 322 can be accurately located by coinciding the scale line with the edge of the reference member.

[0084] Figure 5 yes Figure 1 See the enlarged view of part B in Figure 1 and Figure 5 The clamping device further includes an anti-collision component 4. The anti-collision component 4 includes a first anti-collision portion 41 and a second anti-collision portion 42, which are respectively installed on the opposite sides of the two clamping jaw structures 22; when the two clamping jaw structures 22 approach each other, the first anti-collision portion 41 and the second anti-collision portion 42 abut against each other to limit the minimum distance between the two clamping jaw structures 22 in the first direction X, thereby preventing the two clamping jaw structures 22 from colliding and causing damage.

[0085] For example, one of the first anti-collision portion 41 and the second anti-collision portion 42 is a buffer, and the other is an anti-collision plate, and the buffer and the anti-collision plate are arranged opposite to each other, so that the buffer and the anti-collision plate play a buffering role through the flexible collision, thereby preventing the two clamping jaw structures 22 from having a hard collision. For example, the above-mentioned buffer can be a component with a flexible or elastic buffering function such as a pneumatic buffer and a spring buffer.

[0086] In addition, the anti-collision assembly 4 further includes an anti-collision member 43, which is disposed on the same clamping jaw structure 22 as the buffer and is disposed opposite to the anti-collision plate. The anti-collision member 43 and the anti-collision plate serve as hard stop members to prevent the two clamping jaw structures 22 from colliding due to failure of the buffer. For example, the anti-collision member 43 may be an anti-collision rubber cap screw or an anti-collision column, and extends along the first direction X. If the anti-collision member 43 is an anti-collision rubber cap screw, the distance between the anti-collision member 43 and the anti-collision plate in the first direction X may be adjusted by a thread.

[0087] Continue to refer to Figure 1 Each clamping jaw structure 22 includes an opening and closing member 221, a lifting module 222 and a clamping jaw 223. The opening and closing member 221 is slidably matched with the mounting seat 1 along the first direction X, and is connected to the first driving member 21. The first driving member 21 drives the opening and closing member 221 to slide along the first direction X, and the clamping assembly 3 is arranged on the opening and closing member 221. The lifting module 222 is installed on the opening and closing member 221, and the clamping jaw 223 is connected to the lifting module 222. The lifting module 222 can drive the clamping jaw structure 22 to move along the second direction Z, that is, the clamping jaw 223 can not only realize opening and closing, but also can be lifted and lowered along the second direction Z.

[0088] For example, the above-mentioned opening and closing member 221 is in the form of a long strip plate, and its length direction is aligned with the third direction Y. At least two clamping jaws 223 are provided on one opening and closing member 221, and each clamping jaw 223 includes at least two claws 2231 and a connecting member 2232 for fixing and installing the at least two claws 2231. Among them, the at least two clamping jaws 223 on the same opening and closing member 221 can also be connected by the connecting member 2232, so as to ensure that the at least two clamping jaws 223 on the same opening and closing member 221 can move synchronously under the drive of the lifting module 222.

[0089] Among them, the lifting module 222 includes a second driving member 2221 and a guide rail 2222. The second driving member 2221 is arranged on the opening and closing member 221 and is connected to the clamping jaw 223. The guide rail 2222 extends along the second direction Z. The two ends of the guide rail 2222 in the second direction Z are respectively connected to the opening and closing member 221 and the first adjustment structure 32. The guide rail 2222 is slidably matched with the clamping jaw 223 to guide the movement of the clamping jaw 223 along the second direction Z.

[0090] In order to ensure the smooth movement of the clamping jaws 223, there are two guide rails 2222, which are arranged at intervals along the third direction Y, and both slide with at least two clamping jaws 223 provided on the same opening and closing member 221. In addition, at least two clamping jaws 223 on the same opening and closing member 221 are connected by a connecting member 2232. In this way, the second driving member 2221 only needs to be drivingly connected with the connecting member 2232 to simultaneously drive at least two clamping jaws 223 provided on the same opening and closing member 221.

[0091] Based on this embodiment, for the embodiment in which the clamping assembly 3 further includes a second adjustment structure 33, and the second adjustment structure 33 includes a fixing member 331 and a bolt 332, the two ends of the guide rail 2222 in the second direction Z are respectively connected to the opening and closing member 221 and the fixing member 331. Among them, the clamping assembly 2 further includes a first connecting plate 225, the first connecting plate 225 extends along the second direction Z, and its two ends are respectively connected to the opening and closing member 221 and the first adjustment structure 32, and the guide rail 2222 is connected to the first connecting plate 225. It can be understood that for the embodiment in which the guide rail 2222 has two, the first connecting plates 225 also have two. The two first connecting plates 225 are arranged at intervals along the third direction Y and are connected to the corresponding guide rails 2222.

[0092] The clamping assembly 2 further includes a second connecting plate 226, which includes a middle plate portion and two connecting plate portions arranged on both sides of the middle plate portion in the third direction Y. The two connecting plate portions are connected to two first connecting plates 225 arranged at intervals along the third direction Y. The second driving member 2221 is installed on the middle plate portion. In other words, the second connecting plate 226 is generally in an inverted "T" shape.

[0093] In some embodiments of the present application, reference Figure 1 and Figure 6 The clamping device further includes an anti-drop assembly 5.
