[0033] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1 , a battery cell recycling milling positioning device, comprising a bottom plate, and a downward pressing and leveling component 100, a buffer component 200, and a side pressing component 300 installed on the bottom plate;

[0035] The pressing and leveling component 100 is in an inverted "U" shape as a whole, that is, an arched structure, and is installed in the middle of the bottom plate. The pressing and leveling component 100 is used to level the height of the battery cell.

[0036] The buffer component 200 is installed at the middle position of the top of the bottom plate and is located below the pressing and leveling component 100; the buffer component 200 is used to place batteries of different heights, and the buffer at the bottom can ensure that the top of the battery cell remains at the same height;

[0037] The side clamping assembly 300 is provided in two groups, which are respectively located at the front and rear sides of the top of the bottom plate. Figure 1 shall prevail. Figure 1 The front and rear directions are marked in the figure, and the other directions are based on this as a reference. It should be understood that this direction setting is only for the convenience of description and understanding, and cannot be understood as a limitation of the present invention; the side clamping components 300 located on the front and rear sides can squeeze the buffer component 200, and then position several battery cells inside the buffer component 200.

[0038] Reference Figure 2The pressing and leveling assembly 100 includes a support plate 101, a lower pressing plate 102, a cylinder 103, a locking piece 104 and a slide rail mechanism 105, wherein the support plates 101 are provided in two groups and are arranged perpendicular to the bottom plate, the two groups of support plates 101 are symmetrically distributed on the left and right sides of the top of the bottom plate, and the bottoms of the two groups of support plates 101 are slidably connected to the slide rail mechanism 105 installed on the bottom plate, and a locking piece 104 can be provided at the connection position between the bottom of the support plate 101 and the slide rail mechanism 105 for fixing; a lower pressing plate 102 is slidably connected between the two groups of vertical support plates 101, that is, the lower pressing plate 102 can slide in the vertical direction along the two support plates 101, and the sliding driving mechanism adopts a cylinder 103, the cylinder 103 is arranged on the inner side of the support plate 101, and the output shaft at the top is connected to the lower pressing plate 102, which can drive the lower pressing plate 102 to move in the vertical direction of the support plate 101.

[0039] When in use, the support plate 101 can be adjusted in position by sliding on the slide rail mechanism 105. When the support plate 101 is adjusted to the specified position, the support plate 101 can be fixed to the slide rail mechanism 105 by the locking member 104 to prevent the support plate 101 from shaking. At this time, the lower pressure plate 102 can be driven downward by the cylinder 103 until the battery cells are leveled and the tops of the battery cells are kept at the same horizontal plane. It should be noted that the lower pressure plate 102 of the present application is arranged parallel to the bottom plate, perpendicular to the support plate 101, and parallel to the battery box 204 in the buffer assembly 200.

[0040] Reference Figure 3 and Figure 4 The buffer assembly 200 includes a stepped bolt 201, a rectangular spring 202, a buffer plate 203 and a battery box 204, wherein the battery box 204 is a rectangular box body, and a plurality of buffer grooves arranged equidistantly are opened on the top, and the front and rear sides of each buffer groove pass through the battery box 204, Figure 4 It can be seen that a plurality of buffer grooves can be seen on the front and rear side walls of the battery box 204, and a buffer block 203 is installed inside each buffer groove. The stepped bolt 201 penetrates the corresponding buffer plate 203 and then penetrates the rectangular spring 202 and is connected to the battery box 204, that is, the rectangular spring 202 is sleeved on the stepped bolt 201 and is located below the buffer block 203. Figure 3 It can be seen that it is important to note that the length of the buffer plate 203 is greater than the length of the buffer groove, that is, the front and rear ends of the buffer plate 203 can extend out of the battery box 204, which makes it easier for the subsequent side clamping assembly 300 to position the buffer plate 203. At the same time, the height of the buffer groove must be greater than the height of the buffer plate 203. Such a design can provide a margin for the buffer plate 203 to move up and down.

[0041] When in use, several battery cells are placed in the buffer slots one by one, and the number of battery cells is consistent with the number of buffer slots. Therefore, it can be known that the number of buffer slots can be arranged according to actual conditions or the number of battery cells, and the present application does not limit its number; after the battery cells are installed in the buffer slots, the bottom surface of the battery cells can be in contact with the top of the buffer plate 203. After all the battery cells are installed, the top of the battery cells can be leveled by the lower pressure plate 102, so that the tops of all battery cells are at the same horizontal height. This setting can cleverly solve the problem of being unable to achieve positioning consistency when milling battery cells of different heights, and quickly achieve the flatness of the upper surface of a row of battery cells.

[0042] Reference Figure 5 The side clamping assembly 300 includes a screw 301, a linear bearing 302, a screw mounting plate 303, a guide shaft 304, a screw connecting block 305 and a side pressure plate 306, wherein the side pressure plate 306 is arranged in parallel with the screw mounting plate 303, a screw connecting piece 305 is provided at the middle position of one side of the side pressure plate 306 facing the screw mounting plate 303, a screw 301 is threadedly connected at the middle position of the screw mounting plate 303, a handle is provided at one end of the screw 301, and the other end is movably connected to the screw connecting block 305, so that the screw 301 can be rotated by the handle to push the side pressure plate 306 to move in the front-rear direction, that is, to move toward the buffer plate 203, and at this time the screw mounting plate 303 is stationary;

[0043] Furthermore, a plurality of guide shafts 304 are installed at both ends of the side pressure plate 306 facing the screw mounting plate 303. The guide shafts 304 are arranged parallel to the screw 301. The other end of the guide shaft 304 passes through the screw mounting plate 303. A linear bearing 302 is arranged at the connection with the screw mounting plate 303. Therefore, when the screw drives the side pressure plate 306 to move, the guide shaft 304 can play a certain guiding role in the movement of the side pressure plate 306, and can achieve uniform force on the side pressure plate 306, thereby avoiding the problem of the screw getting stuck during movement.

[0044] The specific operating principles of this application are as follows:

[0045] First, place the battery cells in the battery box 204 in sequence, ensuring that the battery cell poles face upwards;

[0046] Then the slide rail mechanism 205 drives the lower pressing plate 102 and moves the lower pressing plate 102 to a position above the upper surface of the battery cell; under the action of the cylinder 103, the lower pressing plate 102 is driven to squeeze the surface of a row of battery cells. A buffer plate 203 is provided at the bottom of the battery cell. When the battery cell moves downward, it is ensured that the battery cells of different heights can achieve different descending heights, thereby ensuring that the upper surface of the battery cell is on the same horizontal plane;

[0047] Then, by driving the side clamping assemblies 300 on both sides, the side pressure plates 306 clamp the buffer plate 203. At this time, the upper surfaces of all the battery cells are on the same horizontal plane, and the lower pressure plate 102 can be withdrawn;

[0048] Finally, the milling cutter uses the lower pressure plate surface as a positioning reference to mill and recycle the welding scars of the battery cells.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
