When the battery cell is pressed and the dust carried in the battery cell after pressing, it pollutes the internal environment of the equipment as a whole, making it impossible for the environmental requirements of battery cell production to meet the 10,000-level requirements. The risk of short circuit caused by dust pollution to the battery cell is a major quality problem.
[0003] In the related art, when vacuuming the battery cells, it is often overlooked that the negative pressure generated by the vacuuming will cause bending and deformation of the tabs, ultimately affecting the production quality of the battery cells. Summary of the invention

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] An embodiment of the present application provides a battery cell dust removal device, which can set a partition between the first dust suction component and the base to increase the transition space, thereby reducing the negative pressure generated by the first dust suction component, the degree of bending deformation caused to the pole ear, and reducing the degree of damage to the connection between the battery cell and the pole ear.
[0034] It should be noted that the first direction mentioned below is the X-axis direction in the drawings, the second direction is the Y-axis direction in the drawings, and the third direction is the Z-axis direction in the drawings.
[0035] like Figure 1 and 2 As shown, an embodiment of the present application is a battery cell dust removal device, which may include: a base 1, a partition 2 is connected to one side of the base 1, the base 1 is used to set the battery cell 6, and the partition 2 is used to be set below the pole ear 61; a first dust suction component 3, the first dust suction component 3 is connected to the base 1; along the second direction, the base 1, the partition 2 and the first dust suction component 3 are distributed in sequence. Exemplarily, the battery cell 6 can be placed on the top of the base 1, and the partition 2 and the first dust suction component 3 can be connected to the back side of the base 1, and the partition 2 is distributed between the base 1 and the first dust suction component 3.
[0036] Specifically, the battery cell 6 can be laid flat on the top of the base 1, and the pole lug 61 is located on the top of the partition 2. At this time, the first dust suction component 3 can be started to perform dust removal. The dust on the side of the battery cell 6 and the pole lug 61 can be vacuumed by the first dust suction component 3 to reduce the dust accumulated at the connection between the battery cell 6 and the pole lug 61, thereby improving the cleanliness of the product. Because a partition 2 is provided between the first dust suction component 3 and the base 1, the transition space between the first dust suction component 3 and the connection between the battery cell 6 and the pole lug 61 is increased, and the negative pressure generated by the first dust suction component 3 can be weakened, so as to avoid the first dust suction component 3 directly acting on the connection between the battery cell 6 and the pole lug 61, thereby improving the degree of bending and deformation of the pole lug 61 caused by the negative pressure, thereby reducing the degree of damage to the connection between the battery cell 6 and the pole lug 61.
[0037] Furthermore, the partition 2 is fixed with a support portion, and the support portion is used to support the pole ear 61. Figure 1 As shown in the figure, the support portion can be fixed on the top of the partition 2 to support the bottom of the pole ear 61, which can further reduce the degree of bending deformation of the pole ear 61 caused by negative pressure. The support portion can be a flat boss to support the pole ear 61. Of course, in some embodiments, the thickness of the partition 2 can be increased along the third direction as a whole to support the pole ear 61, but the overall increased thickness will reduce the dust collection effect of the first dust collection component 3. Therefore, by separately setting a support portion to support the pole ear 61, the dust collection effect of the first dust collection component 3 can be guaranteed.
[0038] Furthermore, the partition plate 2 is provided with a dust blowing channel 21 , and the dust blowing channel 21 is used to blow dust from the pole ear 61 .
[0039] In some embodiments, along the second direction, the dust blowing channel 21 is opened on the side of the partition 2 facing the base 1. Generally, the battery cell is placed on the base 1, and the pole ear of the battery cell is located above the partition 2. Dust is usually easy to accumulate at the corner between the end face of the battery cell and its supporting surface. By setting the dust blowing channel 21 close to one side of the base 1, the airflow can better blow away the dust at the corner and cooperate with the dust removal work of the first dust suction component 3.
[0040] Of course, in some embodiments, the cross-section of the dust blowing channel 21 is in an inverted trapezoidal shape, and the inverted trapezoidal dust blowing channel 21 can better guide the airflow toward one side of the end face of the battery cell.
[0041] Furthermore, the partition 2 is provided with two air inlet holes 22, the air inlet holes 22 are connected with the dust blowing channel 21, and the dust blowing channel 21 is located between the two air inlet holes 22. If the air inlet hole 22 is only provided at one end of the partition 2, the dust blowing area of the dust blowing channel 21 close to the air inlet hole 22 will have a good effect, while the dust blowing area of the dust blowing channel 21 far from the air inlet hole 22 will have a weak effect, resulting in uneven dust removal of the two pole ears 61; the two air inlet holes 22 can improve the uniform effect of the overall dust blowing area of the dust blowing channel 21, and ensure that the dust removal of the two pole ears 61 is thorough.
[0042] Furthermore, the battery cell dust removal device also includes: two connectors 4, which are spaced apart along the first direction and connected to the base 1; the partition 2 is slidably connected to the two connectors 4 along the second direction; and the first dust collection assembly 3 is connected to the two connectors 4. Exemplarily, the connector 4 can be an L-shaped pipe fitting, one end of which is fixed to the rear side of the base 1, the top of the L-shaped pipe fitting can be used for slidingly installing the partition 2, and the rear side of the L-shaped pipe fitting is used for fixedly installing the first dust collection assembly 3. When the width dimension of the battery cell 6 changes along the second direction, causing the connection between the battery cell 6 and the pole lug 61 to change accordingly, the partition 2 can be appropriately slid along the second direction to adjust the position of the partition 2 to ensure that the partition 2 is in a suitable position below the pole lug 61 to prevent the pole lug 61 from excessive bending and deformation.
[0043] Furthermore, the battery cell dust removal device may further include: a second dust suction component 5, which is arranged on the base 1; the first dust suction component 3 and the second dust suction component 5 are spaced apart and distributed on opposite sides of the base 1 along the second direction. The second dust suction component 5 is added on the basis of the first dust suction component 3, so that the opposite sides of the battery cell 6 (one side is the side where the tab 61 is connected to the battery cell 6) can be dusted, which greatly improves the dust removal effect on the battery cell 6.
[0044] In some embodiments, the first dust suction component 3 and the second dust suction component 5 both include: a dust suction head 31, the dust suction head 31 is provided with a plurality of dust suction holes 32, and the plurality of dust suction holes 32 are spaced apart along the first direction; the battery cell dust removal device may also include: a dust collecting three-way pipe, the two branch pipes of the dust collecting three-way pipe correspond to the two dust suction heads 31 one by one, and are connected to the corresponding dust suction heads 31, and the main pipe of the dust collecting three-way pipe is used to connect with the dust suction pump. The dust suction pump can generate negative pressure to the dust collecting three-way pipe, and then generate negative pressure to the dust suction head 31 through the two branch pipes of the dust collecting three-way pipe, and finally perform dust suction on the opposite sides of the battery cell 6 through the plurality of dust suction holes 32.
[0045] Of course, in some embodiments, the first dust suction component 3 or the second dust suction component 5 includes: a dust suction head 31, the dust suction head 31 is provided with a plurality of dust suction holes 32, and the plurality of dust suction holes 32 are spaced apart along the first direction; a dust suction pipe 33, one end of the dust suction pipe 33 is connected to the dust suction head 31, and the other end thereof is used to connect to a dust suction pump.
[0046] Furthermore, the dust suction direction of the dust suction hole 32 is extended along the third direction. The dust suction direction of the dust suction hole 32 is vertically arranged so that the dust suction direction is not directly opposite to the opposite sides of the battery cell 6, which can further reduce the degree of damage to the connection between the tab 61 and the battery cell 6.
[0047] Furthermore, the inner width of the dust suction head 31 gradually increases along the third direction. As the inner width of the dust suction head 31 gradually increases along the third direction, dust will slide to the bottom of the dust suction head 31, and the dust at the bottom will be extracted through the dust suction pipe 33, which can facilitate dust collection of the dust suction head 31.
[0048] In some embodiments, the width of the dust blowing channel 21 along the second direction may range from 0.1 mm to 1 mm.
[0049] In some embodiments, the air inlet 22 may be connected to an external air pump through a tube.
