For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] When placing the battery cell into the battery case through the shell opening, the protective film on the outer surface of the battery cell may be scratched against the shell wall of the battery case, causing particles on the protective film to remain on the shell wall of the battery case. During the subsequent welding process of the battery case and the cover plate, the particles remaining on the shell wall of the battery case will cause welding problems such as blasting and black marks between the shell wall and the cover plate, affecting the yield rate of battery assembly.

[0043] In order to solve the above problems, Figure 1 to Figure 4As shown, this embodiment provides a battery cell shell dust removal device. The battery cell shell dust removal device includes at least two groups of dust removal components, wherein at least two groups of dust removal components are arranged at intervals along the outer contour of the shell opening 2100 of the battery shell 2000, and each group of dust removal components includes a negative pressure driving member and an abutment member 100. One end of the battery shell 2000 with the shell opening 2100 is simultaneously abutted with the abutment members 100 in at least two groups of dust removal components, and a negative pressure channel 110 is opened in the abutment member 100. The input end of the negative pressure channel 110 is connected to the negative pressure driving member, and the output end of the negative pressure channel 110 is directly opposite to the shell wall of the battery shell 2000 with the shell opening 2100. The negative pressure driving member is used to negatively pressure the negative pressure channel 110.

[0044] The battery cell shell dust removal device is provided by arranging at least two groups of dust removal components along the outer contour of the shell opening 2100 of the battery shell 2000, and making one end of the battery shell 2000 with the shell opening 2100 abut against the abutment members 100 in the at least two groups of dust removal components at the same time, so that the output end of the negative pressure channel 110 in the abutment member 100 is directly opposite to the shell wall of the battery shell 2000 with the shell opening 2100, when the battery cell is placed in the battery shell 2000 along the shell opening 2100 00, if the battery cell and the shell wall at the shell opening 2100 are scratched and particles fall off, the negative pressure driving part in the dust removal assembly can use negative pressure suction of the negative pressure channel 110 to suck away the particles on the shell wall of the shell opening 2100 along the negative pressure channel 110, thereby realizing negative pressure dust removal at the shell opening 2100 of the battery shell 2000 when the battery cell is put into the shell, thereby ensuring the subsequent welding quality and welding yield of the battery shell 2000 and the cover plate, thereby improving the yield rate of battery assembly.

[0045] It should be noted that, in the present embodiment, the battery cell is placed in the battery housing 2000 along the length direction of the battery housing 2000, the size of the battery housing 2000 along the width direction is greater than the size of the battery cell along the width direction, and the size of the battery housing 2000 along the thickness direction is adapted to the size of the battery cell. When the battery cell is placed in the battery housing 2000 along the shell opening 2100, the battery cell is easily scratched with the shell wall arranged oppositely in the shell opening 2100 along the thickness direction. Therefore, two groups of dust removal components are arranged in the battery cell shell entry dust removal device, and the two groups of dust removal components are arranged oppositely along the thickness direction of the shell opening 2100. When the battery cell is placed in the battery housing 2000 along the shell opening 2100, the battery cell first passes through the gap between the two groups of dust removal components and is placed in the battery housing 2000 along the shell opening 2100. At this time, the dust removal components arranged oppositely in the thickness direction of the battery housing 2000 can absorb the residual particles after the battery cell and the shell wall of the shell opening 2100 along the thickness direction are scratched. In other embodiments, the number and location of the dust removal components may be adjusted according to actual needs, and this embodiment does not specifically limit this.

[0046] In addition, in this embodiment, the negative pressure driving member is a negative pressure fan. The negative pressure fan has a simple structure, large output power, and stable output power. In other embodiments, the negative pressure driving member can be a blower or other structure capable of generating negative pressure, which is not specifically limited in this embodiment.

[0047] Specifically, the suction wind speed at the output end of the negative pressure channel 110 is not less than 15m / s. By ensuring that the suction wind speed at the output end of the negative pressure channel 110 is not less than 15m / s, the negative pressure suction effect of the negative pressure channel 110 on the particles remaining on the shell wall of the shell opening 2100 can be ensured, and the problem of being unable to effectively suck the particles remaining on the shell wall of the shell opening 2100 due to the suction wind speed being too small can be avoided. It should be noted that in the present embodiment, the suction wind speed at the output end of the negative pressure channel 110 is 20m / s. It can be understood that in the actual working process, the suction wind speed at the output end of the negative pressure channel 110 can be adjusted according to actual needs. It only needs to ensure that the suction wind speed is greater than 15m / s, and this embodiment does not make specific limitations.

[0048] In an alternative embodiment, if Figure 2 to Figure 4 As shown, an abutting groove 120 is provided at one end of the abutting member 100 close to the battery housing 2000, and the shell wall of the battery housing 2000 at one end where the shell opening 2100 is provided abuts against the groove wall of the abutting groove 120, and the output end of the negative pressure channel 110 is arranged at the groove wall of the abutting groove 120. By providing the abutting groove 120 at one end of the abutting member 100 close to the battery housing 2000, the output end of the negative pressure channel 110 is arranged at the groove wall of the abutting groove 120, and the groove wall of the abutting groove 120 abuts against the shell wall of the end of the battery housing 2000 where the shell opening 2100 is provided, the positioning of the end of the battery housing 2000 where the shell opening 2100 is provided can be achieved, the docking accuracy between the shell wall of the shell opening 2100 and the output end of the negative pressure channel 110 is ensured, and the suction effect of the negative pressure channel 110 on the residual particles on the shell wall of the shell opening 2100 is ensured.

[0049] As an optional solution, at least two groups of negative pressure channels 110 are provided on the abutment 100, and at least two groups of negative pressure channels 110 are interconnected, and any one of at least two groups of negative pressure channels 110 is connected to the negative pressure driving member. By providing at least two groups of negative pressure channels 110 on the abutment 100, and making at least two groups of negative pressure channels 110 interconnected, and setting a negative pressure driving member on any one of at least two groups of negative pressure channels 110, negative pressure dust removal on the shell wall at the shell opening 2100 by all negative pressure channels 110 is achieved, and the negative pressure dust removal effect on the shell opening 2100 is further improved. It should be noted that in this embodiment, if Figure 3As shown, the abutment member 100 is provided with four protrusions spaced apart along the width direction of the battery housing 2000, and each protrusion has a corresponding set of negative pressure channels 110, and the four sets of negative pressure channels 110 are connected to each other and to a negative pressure driving member. In other embodiments, the specific number of negative pressure channels 110 in the abutment member 100 can also be adjusted according to actual needs, and this embodiment does not make a specific limitation.

[0050] In addition, in other embodiments, under the premise of providing at least two groups of negative pressure channels 110 in the abutment 100, the at least two groups of negative pressure channels 110 can also be isolated from each other, and each group of negative pressure channels 110 is provided corresponding to a negative pressure driving member. By providing at least two groups of negative pressure channels 110 on the abutment 100, isolating the at least two groups of negative pressure channels 110 from each other, and providing a negative pressure driving member on each group of negative pressure channels 110, not only can negative pressure dust removal be achieved on the shell wall at different positions on the contour of the shell opening 2100, but also each group of negative pressure channels 110 can be individually controlled to improve the dust removal accuracy.

[0051] In an optional embodiment, the negative pressure channel 110 includes a main channel 111 and at least two branch channels 112, wherein the main channel 111 is in communication with the negative pressure driving member, the main channel 111 is in communication with at least two branch channels 112 at the same time, and the output ends of the at least two branch channels 112 are arranged at intervals on the groove wall of the abutting groove 120 along the contour of the shell opening 2100. By configuring the negative pressure channel 110 as a main channel 111 and at least two branch channels 112 that are in communication with each other, connecting the main channel 111 with the negative pressure driving member, and arranging the output ends of the branch channels 112 at intervals on the groove wall of the abutting groove 120 along the contour of the shell opening 2100, the negative pressure dust removal effect of the negative pressure channel 110 on the shell wall at the shell opening 2100 can be further ensured. It should be noted that, in this embodiment, each group of negative pressure channels 110 includes a main channel 111 and three branch channels 112 that are connected to each other, one end of the three branch channels 112 is connected to the main channel 111, and the other ends of the three branch channels 112 are spaced apart along the abutment groove 120. In other embodiments, the specific number of branch channels 112 can also be adjusted according to actual needs, and this embodiment does not specifically limit it.

[0052] In order to further improve the protection of the battery housing 2000, an elastic protective layer is coated on the groove wall of the abutment groove 120. By coating the elastic protective layer on the end face of the abutment groove 120, when the battery housing 2000 abuts against the abutment groove 120, the elastic protective layer can be compressed and clamped between the battery housing 2000 and the groove wall of the abutment groove 120, preventing the direct contact between the battery housing 2000 and the groove wall of the abutment groove 120, and the elastic protective layer can also use its own elasticity to provide a buffer for the contact between the battery housing 2000 and the abutment groove 120. It should be noted that in this embodiment, the elastic protective layer is made of rubber material. The rubber material has good elasticity, toughness and wear resistance, and has a long service life. In other embodiments, the elastic protective layer can also be made of other elastic materials, which is not specifically limited in this embodiment.

[0053] As an alternative, Figure 5 As shown, the battery cell shelling and dust removal device further includes a shell transfer assembly 200, wherein the shell transfer assembly 200 is configured to drive the battery shell 2000 to abut against the abutment groove 120 on the abutment member 100. By providing the shell transfer assembly 200 to drive the battery shell 2000 to abut against the abutment groove 120, the degree of automation is high, and the subsequent shelling efficiency and shelling accuracy of the battery cell shelling are improved.

[0054] Specifically, the shell transfer assembly 200 includes a gripping member 210 and a transfer driving member 220, wherein the gripping member 210 is used to grip and fix the battery shell 2000, the gripping member 210 is connected to the output end of the transfer driving member 220, and the transfer driving member 220 can drive the gripping member 210 to move arbitrarily relative to the abutting member 100. By setting the gripping member 210 to grip and fix the battery shell 2000, and setting the transfer driving member 220 to drive the gripping member 210 to move arbitrarily relative to the abutting member 100, when it is necessary to abut and fix the battery shell 2000 against the groove wall of the abutting groove 120, the transfer driving member 220 first drives the gripping member 210 to move to the battery shell 2000, then the gripping member 210 grips and fixes the battery shell 2000, and then the transfer driving member 220 drives the gripping member 210 to move until the battery shell 2000 fixed on the gripping member 210 abuts against the groove wall of the abutting groove 120. It should be noted that, in this embodiment, the transfer drive member 220 is a three-axis transfer module, and the three-axis linkage of the three-axis transfer module is used to achieve the effect of driving the gripping member 210 to move arbitrarily relative to the abutting member 100. In other embodiments, the gripping member 210 may also be a six-axis transfer module to further improve the driving efficiency of the gripping member 210. The specific structure and working principle of the three-axis transfer module belong to the prior art and will not be described in detail here.

[0055] In addition, in this embodiment, the gripping member 210 is a vacuum suction cup, the input end of the vacuum suction cup is connected to the vacuum pumping device, and the vacuum suction cup is fixed by adsorption to the outer shell wall of the battery housing 2000. The vacuum suction cup has a good adsorption and fixing effect, and can achieve stable gripping of the battery housing 2000, and will not cause extrusion deformation to the battery housing 2000, thereby improving the protection of the battery housing 2000. In other embodiments, the gripping member 210 may also be an electromagnetic suction cup or other gripping and fixing structure, which is not specifically limited in this embodiment.

[0056] To further improve the transport effect of the battery housing 2000, as Figure 4 As shown, a plurality of shell transfer assemblies 200 are arranged in the battery shell dust removal device, and the plurality of shell transfer assemblies 200 are arranged at intervals on the outer periphery of the battery shell 2000. Specifically, in this embodiment, two groups of shell transfer assemblies 200 are respectively arranged at both ends of the battery shell 2000 in the thickness direction. In other embodiments, the specific number and setting position of the shell transfer assemblies 200 can also be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0057] This embodiment also provides a battery assembly device. The battery assembly device includes a battery cell transfer device, a cover plate transfer device, a welding device, and the above-mentioned battery cell shell dust removal device, wherein the battery cell transfer device is used to transfer the battery cell along the shell opening 2100 into the battery shell 2000, the cover plate transfer device is used to seal the cover plate at the shell opening 2100, and the welding device is used to weld and fix the cover plate to the shell wall at the shell opening 2100. The battery assembly equipment applies the above-mentioned battery cell shell-entry dust removal device. When the battery cell is placed into the battery shell 2000 along the shell opening 2100, if the battery cell and the shell wall at the shell opening 2100 are scratched and particles fall off, the negative pressure driving part in the dust removal component uses negative pressure suction on the negative pressure channel 110 to suck away the particles on the shell wall of the shell opening 2100 along the negative pressure channel 110, thereby realizing negative pressure dust removal at the shell opening 2100 of the battery shell 2000 when the battery cell is put into the shell, ensuring the subsequent welding quality and welding yield of the battery shell 2000 and the cover plate, thereby improving the yield rate of battery assembly.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
