[0064] The second supporting member 2, the third supporting member 4 and the fourth supporting member 6 are all movably arranged on the first supporting member 1, and along the first preset direction a, the fourth supporting member 6 and the second supporting member 2 and the third supporting member 4 are arranged at intervals;

[0065] Along the second preset direction b, the third support member 4 is arranged on the side of the second support member 2, and the second support member 2, the third support member 4 and the fourth support member 6 can all move relative to the first support member 1 along the second preset direction b to adapt to the injection holes and poles in different positions.

[0066] Based on the structure described above, it can be known that the chemical splitting capacity device 100 provided in the present application can adjust the positions of the injection component 3, the first probe 5 and the second probe 7 according to the injection holes and the poles at different positions on the battery 300 when in use. That is to say, the chemical splitting capacity device 100 can be compatible with cylindrical batteries 300 of different models at the same time, which solves the problem of inconvenience in chemical splitting capacity caused by the injection holes of the cylindrical battery 300 and the battery poles being on the same diameter line but without a clearly defined position. At the same time, the device is simple and convenient to operate during use, saving time and effort.

[0067] Further, preferably, the first preset direction a is the Z-axis direction, for example: the height direction of the first supporting member 1, the second preset direction b is the Y direction in the horizontal plane, and the third preset direction c described below is the X direction in the horizontal plane. Of course, it is not limited to this and can also be selected according to actual needs, for example: the second preset direction b is the X direction in the horizontal plane, the third preset direction c is the Y direction in the horizontal plane, and so on.

[0068] In this embodiment, preferably, Figures 2 to 9 As shown, the chemical fractionation device 100 also includes a driving device 8, which is arranged on the first supporting member 1, and the driving end of the driving device 8 is connected to the fourth supporting member 6, for driving the second probe 7 to approach or move away from the first probe 5 along the first preset direction a to adapt to batteries 300 of different heights.

[0069] According to the structure described above, along the first preset direction a, that is, the height direction, the device containing the battery 300 is first placed between the first probe 5 and the second probe 7, and then the fourth supporting member 6 is driven to rise by the driving device 8, thereby driving the second probe 7 to rise, so that the second probe 7 first contacts the pole at the bottom of the battery 300 through the hollow structure on the device, and then continues to rise together with the device containing the battery 300, and finally makes the pole at the top of the battery 300 contact with the first probe 5, and the injection hole of the battery 300 is aligned with the injection member 3. It can be seen that this structure has no limit on the height of the battery 300, and thus can form and divide the capacity of batteries 300 of different heights, and has a wider range of applications.

[0070] Further, preferably, the driving device 8 is a cylinder, but is not limited thereto and may also be a linear motor or the like.

[0071] It should be noted that the above-mentioned driving device 8 and the like may not be provided in the present application, that is, the fourth support member 6 is only adjustable relative to the first support member 1 in the second preset direction b, i.e., in the horizontal plane, and is fixed in the first preset direction a, i.e., in the vertical direction, so as to perform formation and capacity division for batteries 300 of a certain height size. However, in this case, formation and capacity division can still be performed for batteries 300 of different diameters, i.e., batteries 300 with different injection holes and pole positions.

[0072] In this embodiment, preferably, Figures 2 to 4 As shown, the chemical fractionation device 100 further includes a fifth support member 9 and a bearing member 10; wherein the fifth support member 9 is movably disposed on the first support member 1 along a first preset direction a, and the fifth support member 9 is connected to the fourth support member 6 for synchronous movement;

[0074] According to the structure described above, the battery 300 is placed in the installation cavity 1014 of the load-bearing member 10, and the mounting portion of the load-bearing member 10 is mounted on the fifth support member 9. The driving device 8 is then used to drive the fourth support member 6 to rise, thereby driving the second probe 7 to rise, so that the second probe 7 first contacts the bottom pole of the battery 300 through the through hole 1015 on the load-bearing member 10, and then continues to rise, together with the fifth support member 9, the load-bearing member 10 and the battery 300, and finally the top pole of the battery 300 contacts the first probe 5, and the injection hole of the battery 300 is aligned and contacted with the injection member 3.

Of course, it is not limited to this, and only one fifth supporting member 9 and one corresponding mounting part may be provided, which is selected according to actual needs.

[0077] Further, preferably, the fifth supporting member 9 is a flat plate structure, which has a simple structure and is convenient for processing and manufacturing while satisfying the supporting function of the fifth supporting member 9. Of course, the present invention is not limited thereto.

[0078] It should be noted that: the load-bearing member 10 and the fifth supporting member 9 may also be omitted, and only the existing bracket and tray structure may be used, and a hollow structure may be provided at the bottom of the tray. The bracket may be used to lift the tray so that the tray is located between the first probe 5 and the second probe 7. As the driving device 8 drives the fourth supporting member 6 to drive the probes to rise, the tray together with the battery 300 inside it may also be driven to rise.

[0079] In this embodiment, preferably, Fig.10 and Fig.11 As shown, the bearing member 10 includes a material frame 101, a partition plate 102 and a first auxiliary stopper assembly 103; wherein the partition plate 102 is disposed in the material frame 101, and the number of the partition plates 102 is multiple, and they are sequentially spaced along the third preset direction c to divide the material frame 101 into multiple installation cavities 1014; multiple sets of first auxiliary stopper assemblies 103 are provided in any installation cavity 1014, and one is selected for use;

[0080] Any group of first auxiliary limiting components 103 includes two first auxiliary limiting members 1031, which are respectively engaged with the opposite sides of the material frame 101, and the two first auxiliary limiting members 1031 are used to abut against the opposite sides of the battery 300 to limit the battery 300; the dimensions of the first auxiliary limiting members 1031 along the second preset direction b in the multiple groups of first auxiliary limiting components 103 equipped in any installation cavity 1014, such as length, are different, that is, the lengths of the two first auxiliary limiting members 1031 in each group are the same, but the lengths of the first auxiliary limiting members 1031 between groups are different, and one group of the multiple groups of first auxiliary limiting components 103 can be selected for use according to actual needs, rather than using multiple groups of first auxiliary limiting components 103 together.

[0081] According to the structure described above, it can be known that the interior of the material frame 101 is divided into multiple installation cavities 1014 by utilizing multiple partition plates 102, and multiple batteries 300 can be installed at the same time, thereby improving the efficiency of capacity division, and each installation cavity 1014 is equipped with multiple groups of first auxiliary limiting components 103, and then first auxiliary limiting components 1031 of different lengths can be selected according to different diameters of batteries 300, so that the distance between the two first auxiliary limiting components 1031 can be changed, thereby limiting the batteries 300 of different diameters, making the batteries 300 more stable and less prone to shaking.

[0082] Further, preferably, a buckle 10311 is provided on the side of the first auxiliary limiting member 1031 , and the buckle 10311 is in a slot provided on the top of the side plate 1012 .

[0085] The dimensions of the second auxiliary limiting members 1041 along the third preset direction c, such as length, in the multiple groups of second auxiliary limiting assemblies 104 equipped in any installation cavity 1014 are different. That is, the lengths of all the second auxiliary limiting members 1041 in each group are the same, but the length dimensions of the second auxiliary limiting members 1041 between groups are different, and one group can be selected from the multiple groups of second auxiliary limiting assemblies 104 for use according to actual needs, rather than using all the second auxiliary limiting assemblies 104 together.

[0086] According to the structure described above, for each battery 300 in the installation cavity 1014, in addition to using the aforementioned two first auxiliary limiting components 1031 for positioning, in order to further strengthen the battery 300, two second auxiliary positioning components can also be used to limit the other two sides of the battery 300, and by changing the length of the two second auxiliary limiting components 1041, the distance between the two second auxiliary limiting components 1041 can be changed, so that batteries 300 of different diameters can be positioned, thereby improving the positioning effect and having a wider range of applications.
