Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0044] In related technologies, the milling treatment of inventory or after-sales scrapped modules and cells can be used for secondary use or sale. If a vise is used for simple clamping and milling, the improper clamping method may cause large-surface deformation of the cell or inconsistent Z-direction pole height, thereby affecting the milling effect and quality.

[0045] In order to solve the problems in the related art to a certain extent, an embodiment of the present application provides a battery cell pole milling positioning device. Since the upper pressure plate of the battery cell adopts an insulating block embedded in the upper pressure plate body for top limitation, it not only ensures the yield strength of the upper pressure plate, but also avoids sparks between the battery cells due to aluminum chips during the milling process, thereby achieving the beneficial effects of simple process, low labor cost and high efficiency in the positioning and clamping process before battery cell milling.

[0046] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0047] Combine Figure 1-Figure 3 , the embodiment of the present application provides a battery cell pole milling and positioning device, including a battery cell mounting base 10, a hand valve 20 is provided on the top of the battery cell mounting base 10;

[0048] A cell mounting base 30 is provided on the top of the cell mounting base 10. The cell mounting base 30 includes: a box body 31 fixedly connected to the top of the cell mounting base 10; a cell baffle 32 arranged parallel to the inside of the box body 31;

[0049] The top of the box body 31 is clamped with the battery cell upper pressure plate 40, which includes: an upper pressure plate body 41, which is clamped on the top of the box body 31; an insulating block 42, which is arranged on the upper surface of the upper pressure plate body 41; and a pole through hole 43, which is opened on the upper surface of the insulating block 42.

[0050] The interior of the box body 31 is provided with a lifting assembly 50, which includes: a cylinder connecting plate 51, which is provided on the inner wall of the box body 31; a cylinder 52, which is installed on the bottom of the cylinder connecting plate 51; and a battery backing plate 53, which is fixedly connected to the telescopic end of the cylinder 52;

[0056] During operation, first place the battery cells into the battery cell slots formed by the battery cell baffle 32, so that the battery cells are on the battery cell pad 53, turn the hand valve 20 to control the cylinder 52 to rise, and the battery cells are lifted upward, so that the battery cell poles pass through the pole through holes 43 on the insulating block 42 (after the battery cell poles pass through, it is necessary to pay attention to whether the pole sealing ring is pressed under the insulating block 42. If there is interference, the position of the battery cell 6 needs to be fine-tuned to ensure that the pole sealing ring is exposed).

[0057] In order to ensure that multiple cylinders 52 are extended synchronously, multiple cylinders 52 are controlled by the same valve, and the valve and the box body 31 are set on the same workbench for easy operation (because the thickness of the contact part between the insulating block 42 and the shoulder of the battery cell is 2.5 mm, and the yield strength theoretically meets the medium pressure jacking requirement, the pressure of the cylinder 52 needs to be adjusted to as low as possible to ensure that the battery cell will not shake after jacking and the pole milling cutter will not cause the battery cell to shake during the milling process).

[0058] In some embodiments, the battery cell mounting base 30 further includes: reinforcing ribs 33 symmetrically arranged on both sides of the box body 31 . The reinforcing ribs 33 are provided to improve the strength of the box body 31 .

[0059] In some embodiments, the bottom of the upper pressing plate body 41 has reinforcing ribs, and the overall strength of the upper pressing plate body 41 is improved by providing the reinforcing ribs.

[0060] In some embodiments, there are eight insulating blocks 42 .

[0061] In some embodiments, the pole through-hole 43 cooperates with the battery cell pole.

[0062] In some embodiments, the battery cell upper pressure plate 40 further includes: an explosion-proof valve groove 44, which is opened on the upper surface of the insulating block 42; the explosion-proof valve groove 44 is grooved to avoid the battery cell explosion-proof valve.

[0063] In some embodiments, the lifting assembly 50 further includes: guide rods 54 symmetrically arranged on both sides of the cylinder 52; the guide rods 54 slide in conjunction with the cylinder connecting plate 51 to guide the battery cell pad 53 to ensure its vertical sliding.

[0064] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification.

[0065] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.
