[0037] The following reference Figures 1 to 9 This application describes a spacing device according to some embodiments.

[0038] See Figures 1 to 9 As shown, an embodiment of this application provides a separation device, including: an upper separation mechanism 1 and a lower separation mechanism 2; wherein, the upper separation mechanism 1 includes an upper driving device 11, an upper connecting member 12 and an upper separation assembly 13, the driving end of the upper driving device 11 is connected to the upper connecting member 12; the upper separation assembly 13 is slidably connected to the upper connecting member 12, and the upper separation assembly 13 is formed with a plurality of upper separation protrusions 1311 arranged at equal intervals along a first preset direction a, that is, along the first preset direction a, the distance between any two adjacent upper separation protrusions 1311 is equal; the plurality of upper separation protrusions 1311 are used to be inserted from top to bottom along a second preset direction b between the tops of a plurality of corresponding objects to be separated, so that any two adjacent objects to be separated are separated at equal intervals;

[0039] The lower spacing mechanism 2 includes a lower driving device 21, a lower connecting member 22, and a lower spacing assembly 23. The driving end of the lower driving device 21 is connected to the lower connecting member 22. The lower spacing assembly 23 is slidably connected to the lower connecting member 22, and the lower spacing assembly 23 has a plurality of lower spacing protrusions 2311 arranged at equal intervals along a first preset direction a. That is, along the first preset direction a, the distance between any two adjacent lower spacing protrusions 2311 is equal. 1 is used to insert from bottom to top along the second preset direction b between the bottoms of a plurality of objects to be separated, so that any two adjacent objects to be separated are separated at equal intervals; the plurality of upper separation protrusions 1311 and the plurality of lower separation protrusions 2311 are in one-to-one correspondence and are arranged opposite to each other along the second preset direction b, that is, along the first preset direction a, the distance between any two adjacent upper separation protrusions 1311 and the distance between any two adjacent lower separation protrusions 2311 are equal.

[0040] Based on the structure described above, the general working process of the separation device provided in this application is as follows: The restraint tray 3, in which the battery cells are installed, moves along the first preset direction a between the upper separation mechanism 1 and the lower separation mechanism 2. Then, the upper drive device 11 drives the upper separation component 13 to move toward the upper partition of the tray. At the same time, the lower drive device 21 drives the lower separation component 23 to move toward the lower partition of the tray until each upper separation protrusion 1311 is correspondingly inserted into the gap of the upper partition of the restraint tray 3 and extends to the top of the corresponding two adjacent battery cells. Each lower separation protrusion 2311 is correspondingly inserted into the gap of the lower partition of the restraint tray 3 and extends to the bottom of the corresponding two adjacent battery cells, thereby uniformly separating all the battery cells, which also serves as a separation function. Thus, during the process of unrestraining the restraint tray 3, i.e., opening the clamp, the consistency of the clamping distance is maintained, ensuring the stability of the battery being pushed out by the restraint clamp, reducing the problem of battery ejection jamming caused by uneven clamping, helping to improve the utilization rate of the equipment, and thus increasing output.

[0041] Furthermore, preferably, the first preset direction a can be the X direction in the horizontal plane; the second preset direction b can be the vertical direction. Of course, it is not limited to this, and can be designed according to actual needs.

[0042] In this embodiment, preferably, as follows: Figure 2 and Figure 3 As shown, the upper splitting mechanism 1 also includes a first upper support member 14, a second upper support member 15, an upper guide post 16, and an upper guide sleeve 17; wherein, the fixed end of the upper driving device 11 is connected to the second upper support member 15, the driving end of the upper driving device 11 is connected to the second upper support member 15, and the upper connecting member 12 is connected to the second upper support member 15; the upper guide post 16 is connected to the second upper support member 15, and the upper guide sleeve 17 is connected to the first upper support member 14, and the upper guide post 16 is slidably inserted into the upper guide sleeve 17;

The first upper support member 14 is connected to the third upper support member 18, and the fourth upper support member 19 is connected between the second upper support member 15 and the upper connecting member 12. The third upper support member 18 can be fixed at the target location and remain stationary. It should be noted that the third upper support member and the fourth upper support member 19 may not be provided. For example, firstly, the first upper support member 14 can be directly fixed at the target location; secondly, the second upper support member 15 can be directly connected to the upper connecting member 12, etc., depending on the actual needs.

[0044] As can be seen from the structure described above, the first upper support member 14, the second upper support member 15, the third upper support member 18, and the fourth upper support member 19 serve as the main support, supporting the upper drive device 11, the upper connecting member, and the upper pitch assembly 13, making the overall structure more stable and reliable. The upper guide post 16 can slide relative to the upper guide sleeve 17, thereby playing a sliding guiding role. In other words, it plays a guiding role in the movement of the upper pitch assembly 13 in the second preset direction b, preventing it from shifting and causing uneven pitch in the later stage.

[0045] Furthermore, preferably, there are four upper guide posts 16 arranged in a square array around the upper drive device 11. Correspondingly, there are also four upper guide sleeves 17, which correspond one-to-one with the four upper guide posts 16, resulting in a more even distribution and improved guiding effect. Of course, this is not the only option; the number of upper guide posts 16 can also be three, two, or even one, depending on the actual needs.

[0046] Furthermore, preferably, the third upper support member 18 can be a hollow rectangular beam, and there are two of them, which are respectively arranged at intervals on opposite sides of the upper drive device 11. While meeting the strength requirements, they are lightweight, which is conducive to lightweight design. Preferably, the width direction of the third upper support member 18 is consistent with the first preset direction a. Of course, it is not limited to this and can be selected according to actual needs.

[0047] Furthermore, preferably, the first upper support member 14 is a rectangular flat plate structure, which meets the requirements of assembly and support while being simple in structure and easy to process and manufacture. Preferably, the length direction of the first upper support member 14 is consistent with the first preset direction a. Of course, it is not limited to this and can be selected according to actual needs.

[0048] Furthermore, preferably, the second upper support member 15 is a rectangular flat plate structure, which meets the requirements of assembly and support while being simple in structure and easy to manufacture. Preferably, the length direction of the second upper support member 15 is consistent with the length direction of the first upper support member 14, and the width direction of the second upper support member 15 is consistent with the width direction of the first upper support member 14. Of course, it is not limited to this, and can be selected according to actual needs.

[0049] Furthermore, preferably, the fourth upper support member 19 is a rectangular plate, and its width direction is consistent with the first preset direction a. Preferably, there are two fourth upper support members 19, and they are respectively arranged on opposite sides of the upper driving device 11 along the first preset direction a.

[0050] Furthermore, preferably, the upper connecting member 12 is a rectangular plate, with its length direction aligned with the first preset direction a and its width direction aligned with the third preset direction c. Of course, it is not limited to this and can be selected according to actual needs.

[0051] Based on the above structure, there are two upper connecting members 12, which are respectively arranged on opposite sides of the upper spacing component 13 along a direction perpendicular to the first preset direction a.

[0053] As can be seen from the structure described above, by moving the upper slider 111 relative to the upper slide rail 110, the upper spacing component 13 moves relative to the upper connecting component 12, thereby spacing all the battery cells according to the preset spacing, which has a wider range of applications and can also play a guiding role during the movement.

[0054] Furthermore, preferably, the upper slide rail 110 extends along a first preset direction a.

[0055] It should be noted that, in addition to the above, the upper slide rail 110 can also be connected to the upper spacing component 13, and the upper slider 111 can be connected to the upper connecting member 12, etc., depending on the actual needs.

[0057] As can be seen from the structure described above, an upper slide rail 110 is provided on each of the opposite sides of the upper spacing component 13, thereby making the upper spacing component 13 move more smoothly. Of course, only one upper slide rail 110 can be provided, depending on the actual needs.

[0058] In this embodiment, preferably, as follows: Figures 4 to 6As shown, the upper spacing component 13 includes an upper spacing member 131 and an upper auxiliary connector 132; wherein, there are multiple upper spacing members 131, which are sequentially spaced along a first preset direction a, and any two adjacent upper spacing members 131 are connected by a corresponding upper auxiliary connector 132; each upper spacing member 131 is slidably connected to the upper connecting member 12, and each upper spacing member 131 forms an upper spacing protrusion 1311. Of course, it is not limited to this, each upper spacing member 131 may form multiple upper spacing protrusions 1311, and the multiple upper spacing protrusions 1311 are sequentially spaced along a third preset direction c.

[0059] As can be seen from the structure described above, multiple upper spacing components 131 are connected by the aforementioned upper auxiliary connector 132 to form a whole, and the whole can move synchronously. That is, all the upper spacing protrusions 1311 move synchronously along the first preset direction a, so that all the cells can be clamped at equal intervals. In addition, the upper spacing protrusions 1311 are individually processed on each upper spacing component 131, which makes it more convenient to process and manufacture.

[0060] Furthermore, preferably, the upper dividing member 131 is a rectangular plate, and its length direction is perpendicular to the first preset direction a, which is also the third preset direction c, and its width direction is consistent with the first preset direction a. Of course, it is not limited to this and can be designed according to actual needs.

[0061] Furthermore, preferably, the upper auxiliary connector 132 is a rectangular plate extending along the first preset direction a, and it can be disposed on the outside of the upper spacing member 131. Of course, it is not limited to this and can be designed according to actual needs.

[0064] In this embodiment, preferably, as follows: Figure 3As shown, the upper pitching mechanism 1 also includes an upper pitching auxiliary drive device 113.

Preferably, the fixed end of the upper pitching auxiliary drive device 113 is connected to the second upper support member 15, i.e. fixedly connected. The upper connecting member 12 is connected to the second upper support member 15 through the fourth upper support member 19. Therefore, the fixed end of the upper pitching auxiliary drive device 113 and the upper connecting member 12 can also be indirectly connected. Of course, it is not limited to this. The fixed end of the upper pitching auxiliary drive device 113 can also be directly connected to the upper connecting member 12, i.e. fixedly connected. The driving end of the upper pitching auxiliary drive device 113 is connected to the upper pitching assembly 13 and is used to drive the upper pitching assembly 13 to move all the upper pitching protrusions 1311 along the first preset direction a.

[0065] As can be seen from the structure described above, the upper spacing component 13 can be driven to move along the first preset direction a using the drive end of the upper spacing auxiliary drive device 113, thereby meeting the opening and closing requirements of different spacings. Of course, this upper spacing auxiliary drive device 113 can also be omitted, and the upper spacing component 13 can be moved along the first preset direction a by manually pulling it, etc.

[0066] Furthermore, preferably, the upper splitting mechanism 1 may also include an upper mounting base 112, which is fixed on several of the upper splitting components 131, and the driving end of the upper splitting auxiliary drive device 113 is connected to the upper mounting base 112.

The specific choice depends on the actual needs.

[0070] As can be seen from the structure described above, the first lower support member 24, the second lower support member 27, and the third lower support member 28 serve as the main support, supporting the lower drive device 21, the lower connecting member, and the lower pitch assembly 23, making the overall structure more stable and reliable. The lower guide post 25 can slide relative to the lower guide sleeve 26, thereby playing a sliding guiding role. In other words, it plays a guiding role in moving the lower pitch assembly 23 in the second preset direction b, preventing it from shifting and causing uneven pitch in the later stages.

[0071] Furthermore, preferably, there are four lower guide posts 25 arranged in a square array around the upper drive device 11. Correspondingly, there are also four lower guide sleeves 26, each corresponding one-to-one with the four lower guide posts 25, resulting in a more even distribution and improved guiding effect. Of course, this is not the only option; the number of lower guide posts 25 can also be three, two, or even one, depending on the actual needs.

[0072] Furthermore, preferably, the second lower support member 27 can be a hollow rectangular beam, and there are two of them, which are respectively arranged at intervals on opposite sides of the lower drive device 21 along a direction perpendicular to the first preset direction a, i.e., the third preset direction c.
