[0024] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0026] Reference Figure 1 and Figure 2 This application provides a gripping device, which includes a variable-distance mechanism 1 and a plurality of gripping mechanisms 2. The plurality of gripping mechanisms 2 are connected to the variable-distance mechanism 1, and each gripping mechanism 2 includes an interconnected drive component and a gripping component 21. The drive component is used to drive the gripping component 21 to grip an item; wherein, the variable-distance mechanism 1 is used to drive two adjacent gripping mechanisms 2 to move away from or towards each other.

[0027] Based on the above structure, the gripping device involved in this application can adjust the spacing of the gripping mechanisms 2, thereby enabling spacing adjustment for different batches of battery cells and other items. Furthermore, each gripping mechanism 2 has an interconnected drive assembly and gripping assembly 21; therefore, each gripping assembly 21 can operate independently, making the gripping operation more flexible.

[0028] Reference Figure 3 and Figure 4In some embodiments, the pitch-changing mechanism 1 includes a motor 11, a pitch-changing lead screw 12, and a plurality of first sliders 13. The plurality of first sliders 13 are connected to the pitch-changing lead screw 12, and each first slider 13 is connected to any gripping mechanism 2. The pitch-changing lead screw 12 is connected to the motor 11, which drives the pitch-changing lead screw 12 to rotate, causing the pitch-changing lead screw 12 to move the plurality of first sliders 13 closer or further apart. The surface of the pitch-changing lead screw 12 has multiple thread segments, and each thread segment is screwed onto a corresponding first slider 13. The thread directions on either side of the pitch-changing lead screw 12 are different, with the center of the pitch-changing lead screw 12 serving as the dividing line. When the motor 11 rotates forward, the plurality of first sliders 13 drive the plurality of gripping mechanisms 2 to move towards the center to reduce the spacing. When the electrodes rotate in reverse, the plurality of first sliders 13 drive the plurality of gripping mechanisms 2 to move to both sides to increase the spacing. It is understood that because the first sliders 13 move towards the center, the outermost first slider 13 has the longest stroke. Furthermore, the angle and proportion of each thread will vary. The specific settings of the variable pitch screw 12 can be referenced from the structure of the variable pitch device in related technologies. Users can set the thread angle and ratio according to their actual needs.

[0029] Reference Figure 4 In some embodiments, the variable pitch mechanism 1 further includes a slide rail 14 and a plurality of second sliders 15, the plurality of second sliders 15 being slidably connected to the slide rail 14, and any second slider 15 being connected to any gripping mechanism 2.

[0030] Reference Figure 5 and Figure 6 In some embodiments, the driving assembly includes a telescopic driving assembly 22 and a gripping driving assembly 23. The telescopic driving assembly 22 is connected to the gripping assembly 21, and is used to drive the gripping assembly 21 to move toward or away from the object. The gripping driving assembly 23 is used to drive the gripping assembly 21 to grip the object. Thus, the gripping assembly 21 can not only grip the object under the drive of the gripping driving assembly 23, but also, under the drive of the telescopic driving assembly 22, each gripping assembly 21 can individually adjust its distance from the object. For example, the telescopic driving assembly 22 can drive the gripping assembly 21 to extend, thereby gripping the object more accurately.

[0031] Specifically, refer to Figure 1In some examples, the gripping device may include 16 gripping mechanisms 2, with the drive mechanisms arranged in an 8-row, 2-column configuration. Due to the telescopic drive assembly 22, some gripping components 21 can extend to grasp objects. For example, when multiple battery cells are arranged in a 5-row, 2-column configuration, the corresponding gripping components 21 can extend under the drive of the telescopic drive assembly 22, without requiring all 16 gripping components 21 to extend simultaneously. Therefore, each gripping mechanism 2 is equipped with a telescopic drive assembly 22, which better corresponds to different battery cell arrangements, driving the corresponding gripping components 21 to extend, resulting in more flexible operation. Conversely, if multiple gripping components 21 can only extend or retract uniformly, the gripping components 21 that are not needed may collide with other external objects, causing damage to both the gripping device and the external objects.

[0032] In some embodiments, the telescopic drive assembly 22 includes a telescopic drive body, a telescopic rod, a connector 221, and a guide rod 222. The telescopic drive body is connected to the telescopic rod, and the telescopic rod is connected to the gripping assembly 21, driving the gripping assembly 21 to perform telescopic movement in a first direction. The connector 221 is connected to the telescopic drive body and is also connected to the pitch mechanism 1. The guide rod 222 passes through the connector 221 and is parallel to the telescopic rod. Thus, the gripping assembly 21 can perform telescopic movement in the first direction. Simultaneously, by providing the guide rod 222, the linearity and positioning accuracy of the gripping assembly 21 during telescopic movement are ensured, and the stability during movement is significantly improved, thereby increasing gripping efficiency and operational precision.

[0033] In some examples, the telescopic actuator body can be the cylinder body of a cylinder, and the telescopic rod can be the piston rod of a cylinder.

[0034] In some embodiments, the gripping drive assembly 23 includes a gripping mounting base 231 and a clamping drive member. The gripping mounting base 231 is connected to the telescopic rod of the telescopic drive assembly 22. The clamping drive member is mounted on the gripping mounting base 231, and the gripping assembly 21 is connected to the clamping drive member. The clamping drive member is used to drive the gripping assembly 21 to grip an item. In some examples, the gripping assembly 21 has a first clamp 211 and a second clamp 212 disposed opposite to each other. The clamping drive member may include a motor, a lead screw, and two nuts. The motor is connected to the lead screw, which has symmetrically distributed positive and negative threads. The two nuts are screwed to the lead screw at the positive and negative threads, respectively. The first clamp 211 and the second clamp 212 are respectively connected to the two nuts. The motor drives the lead screw to rotate forward or backward, thereby driving the two nuts to move closer or further apart, thus causing the first clamp 211 and the second clamp 212 to move closer or further apart to grip or release an item.

[0035] Reference Figure 6In some embodiments, the gripping component 21 includes a protective member 213, and a first clamp 211 and a second clamp 212 disposed opposite to each other; the mounting base has a travel groove, the first clamp 211 and the second clamp 212 pass through the travel groove and are connected to the gripping drive member; the two ends of the protective member 213 are respectively connected to the first clamp 211 and the mounting base, or the two ends of the protective member 213 are respectively connected to the first clamp 211 and the second clamp 212, or the two ends of the protective member 213 are respectively connected to the second clamp 212 and the mounting base; the protective member 213 covers the travel groove, and the protective member 213 includes a folding part, which can be folded or unfolded under the drive of the first clamp 211 or the second clamp 212. Therefore, even if the first clamp 211 or the second clamp 212 moves, the design of the folding part ensures that the protective part 213 always covers the travel groove, thereby protecting the clamping drive and other components inside the mounting base and reducing the entry of dust, liquid, and other impurities from the travel groove. Specifically, the folding part can have multiple creases, and the creases are perpendicular to the extension direction of the travel groove, allowing the folding part to fold along the creases.

[0036] Understandably, when the clamping drive unit drives the first clamp 211 and the second clamp 212 to move, the first clamp 211 and the second clamp 212 can move along the travel groove and move closer or further apart from each other. When the first protective member 213 and the second protective member 213 move closer to each other, the protective member 213 connected to the first clamp 211 and the second clamp 212 respectively will be compressed, and the folded part will be in a folded state. When the first protective member 213 and the second protective member 213 move further apart from each other, the protective member 213 connected to the first clamp 211 and the second clamp 212 respectively will be stretched, and the folded part will be in an unfolded state. Similarly, when the protective member 213 is connected to the first clamp 211 and the mounting base respectively, the protective member 213 will also be compressed or stretched by the first clamp 211, so that the folded part will be folded or unfolded. When the protective member 213 is connected to the second clamp 212 and the mounting base respectively, the protective member 213 will also be compressed or stretched by the second clamp 212, so that the folding part will fold or unfold. Of course, in some examples, the protective member 213 can be provided between the mounting base and the first clamp 211, between the first clamp 211 and the second clamp 212, and between the second clamp 212 and the mounting base.

[0037] In some embodiments, the gripping assembly 21 includes a first clamp 211, a second clamp 212, and a buffer pad 214 disposed opposite to each other. The buffer pad 214 is connected to the side of the first clamp 211 facing the second clamp 212, and the buffer pad 214 is connected to the side of the second clamp 212 facing the first clamp 211. The buffer pad can be made of a non-metallic material, such as rubber or plastic. Therefore, when the gripping assembly 21 grips items such as battery cells, the buffer pad can absorb some of the impact force, protecting the battery cells from mechanical damage and preventing scratches or wear on the surface of the battery cells.

[0038] In some examples, the cushioning pad 214 may also have multiple anti-slip grooves. These anti-slip grooves increase the friction between the cushioning pad and the object, preventing the gripping device from slipping during the gripping of items such as battery cells.

[0039] Reference Figure 1 In some embodiments, the gripping device further includes a mounting member 3, and the pitch-changing mechanism 1 includes a first pitch-changing mechanism 1 and a second pitch-changing mechanism 1, which are distributed and connected to opposite sides of the mounting member 3; the gripping mechanism 2 is connected to the side of the pitch-changing mechanism 1 away from the mounting member 3. Thus, the gripping device can also be equipped with more gripping mechanisms 2.

[0040] In some examples, the number of gripping mechanisms 2 connected to the first pitch mechanism 1 is equal to the number of gripping mechanisms 2 connected to the second pitch mechanism 1. The more even distribution of gripping mechanisms 2 on both sides of the mounting member 3 helps the gripping device maintain balance during gripping and movement.

[0041] This application also provides a feeding device, which includes the gripping device described above.

[0042] In summary, the gripping device of this application can adjust the spacing of the gripping mechanisms 2, thereby enabling spacing adjustment for different batches of items such as battery cells. Furthermore, each gripping mechanism 2 has interconnected drive components and gripping components 21; therefore, each gripping component 21 can operate independently, making the gripping operation more flexible.
