Description

[Technical Field]

[0001] This invention relates to the field of chemical composition and, in particular, to a chemical composition and restraint tray. [Background Technology]

[0002] In current battery production processes, pre-forming typically uses ordinary trays and a small number of insert-type restraint trays. During the cut-and-go conversion process, different battery trays are required for different models of prismatic batteries. Currently, the conversion method involves replacing the tray separators to enable the production of different battery models. However, this method of replacing tray separators can only adjust the cell thickness, not the height or length. The same tray cannot be switched to test cells with different numbers of channels; only trays with a single cell testing channel number can be used, resulting in high manufacturing costs. After the tray is decompressed, the battery expansion may cause difficulties in separating the restraint plates, and there is no fast, stable, and reliable cell separation device to complete the cell unrestraint process.

[0003] In summary, the main shortcomings of the existing technology are: 1. After the restraint tray is decompressed, the square battery cells cannot smoothly, synchronously, and quickly detach from the silicone contact surface at an equal distance. 2. The restraint tray is not compatible with the different center distances of the battery cells resulting from simultaneous changes in the thickness of the square battery cells and the number of test channels. 3. The pressure locking of the restraint tray is not compatible with the locking center height resulting from different height dimensions of the square battery cells. [Summary of the Invention]

Detailed Implementation Methods

[0081] In the description of the present invention, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of the present invention.

[0082] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0083] The overall concept of this invention is as follows:

[0084] (1) Through the thickness adjustment block 6 and the length and height adjustment block 5, it can be compatible with different cell center distances caused by the simultaneous change of the thickness of the square cell 100 and the number of test channels.

[0085] (2) The linkage mechanism 9 enables the square battery cell 100 to quickly, smoothly, synchronously, and equidistantly disengage;

[0086] (3) The height of the pressurizing mechanism 10 is adjustable, which can accommodate the different locking center heights of the square battery cells 100.

[0087] Please see Figures 1 to 17 As shown.

[0088] A type of volumetric restraint tray, comprising:

[0089] The support frame 1 has at least one receiving cavity 11 inside;

[0090] There are several restraint and limiting blocks 2, each with a first vertical receiving groove 21. The restraint and limiting blocks 2 are movably connected to each receiving cavity 11 and arranged in a row within each receiving cavity 11. The square battery cell 100 can be placed directly in the first vertical receiving groove 21, or the length and height adjustment block 5 can be installed in the first vertical receiving groove 21, and then the square battery cell 100 can be installed on the length and height adjustment block 5. In this case, it can accommodate two variations in the length and height of the square battery cell. Furthermore, in a specific implementation, the length and height adjustment block 5 includes a series of spare parts with the same shape but different sizes. The spare parts of the corresponding size can be selected according to the length and height specifications of the square battery cell 100 and installed in the first vertical receiving groove 21, thereby accommodating the usage needs of more specifications of square battery cells.

[0091] Several thickness adjustment blocks 3 are provided, and the front or rear face of each restraint block 2 is detachably connected to the thickness adjustment block 3. First, the thickness adjustment block 3 can be mounted on or removed from the restraint block 2, thereby adjusting the spacing between the cells to accommodate variations in the thickness of two types of square cells. Alternatively, a series of spare thickness adjustment blocks of different sizes can be manufactured, and the appropriate size spare thickness adjustment block can be selected and mounted according to the thickness of the square cell 100 to accommodate variations in the thickness of the square cell 100. Combined with length and height adjustment blocks 5, this achieves compatibility with variations in the length, width (i.e., thickness), and height of the square cell 100, as well as variations in the number of adjustment channels (i.e., the number of tests conducted on the square cell 100).

[0122] There are at least two bolts, numbered 102.

[0123] A crossed roller bearing 103 is fixed in the middle of the bearing housing 101; it can reduce the friction between the screw 104 and the bearing housing 101.

[0124] The screw 104 is fixedly embedded in the inner ring of the crossed roller bearing 103 at its rear end, and passes forward through the first vertical adjustment hole 121 at its front end;

Simultaneously, the ends of the connecting rods 91 at the front and rear ends are connected to the bottom of the end limit blocks 6. This causes the restraint blocks 2 and the end limit blocks 6 to open or close synchronously and at equal intervals.

[0133] In one specific embodiment, a circular hole 911 is formed in the center of the connecting rod 91, and strip-shaped holes 912 are formed at both ends. Threaded holes 27 are formed at the bottom of the restraint block 2 and the end limit block 6, respectively. A screw is passed through the circular holes 911 of the two connecting rods 91, and then a hexagonal nut is used to lock them together, but not completely, allowing the two connecting rods 91 to rotate. Then, a screw 92 is passed through the strip-shaped holes 912 of the two connecting rods 91, and then locked into the threaded hole at the bottom of the restraint block 2 or the end limit block 6, but not completely, ensuring that the screw can slide within the strip-shaped hole 912. As shown in Figure 12, the figure only illustrates the connection diagram of the restraint block 2 and the connecting rod 91; the connection of the end limit block 6 and the connecting rod 91 adopts the same connection method, which is not shown in the figure.

[0134] Each vertical adjustment hole can be a strip-shaped hole or an elliptical hole, as shown in the attached diagram. Figure 11 In the embodiment shown, the second vertical adjustment hole 1011, and the attached Figure 1 The first vertical adjustment hole 121 is shown. Alternatively, multiple through holes arranged in a vertically spaced row can be used, each corresponding to a different height position to match the height variation of the battery cell. In use, the appropriate through hole is selected and locked in according to the height of the battery cell, as shown in the attached diagram. Figure 4 The third vertical adjustment hole 122 is shown.

[0135] Specific usage instructions:

[0136] For example, a pneumatic screwdriver can be used as the pressurizing device, with an internal hexagonal socket sleeve installed on the pneumatic screwdriver and fitted onto the external hexagonal head 1041.

[0137] Based on the length, width, and height of the square battery cell 100, select and install the thickness adjustment block 3, length and height adjustment block 5, and end partition 8 of the appropriate specifications, or you can choose not to install them; adjust the height of the pressurizing mechanism 10 and adjust the pressurizing center. Then install the square battery cell 100.

[0138] When pressurization is applied, if the pressurization device can rotate forward, it will drive the screw 104 to move towards the rear support plate 13, apply pressure to the restraint plate 7, drive the linkage mechanism 9 to contract, and then drive each of the restraint limiting blocks 2 and the end limiting blocks 6 to contract synchronously and at equal distances, and push the square battery cell 100 to the predetermined clamping position.

[0139] When it is necessary to remove the square battery cell 100, the pressure device rotates in the opposite direction, causing the screw 104 to move away from the rear support plate 13, thereby causing the restraint plate 7 to retract and reset, and then causing the linkage mechanism 9 to open, and finally causing each of the restraint limiting blocks 2 and the end limiting blocks 6 to open synchronously and equidistantly, so that the square battery cell 100 can be taken out.

[0140] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
