[0106] At present, from the perspective of market development, the application of batteries is becoming more and more extensive. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of battery application areas, its market demand is also constantly expanding.

[0107] The electrical equipment using batteries as power sources may be, but is not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys may include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft may include airplanes, rockets, space shuttles, and spacecraft, etc.

[0108] The battery may include a plurality of battery assemblies and a battery case, wherein the plurality of battery assemblies are contained inside the battery case. The battery case is used to contain the battery assemblies to prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells. The battery case may be a simple three-dimensional structure such as a single cuboid, cylinder or sphere, or a complex three-dimensional structure composed of simple three-dimensional structures such as cuboids, cylinders or spheres. The material of the battery case may be an alloy material such as aluminum alloy, iron alloy, or a polymer material such as polycarbonate, polyisocyanurate foam plastic, or a composite material such as glass fiber and epoxy resin.

[0109] In order to meet different power requirements, a battery assembly may include multiple battery cells, which refer to the smallest unit that makes up a battery assembly. Multiple battery cells can be connected in series and / or in parallel via electrode terminals for various applications. Battery cells may include, but are not limited to, lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries. In addition, the shape of the battery cell includes, but is not limited to, a cylinder, a flat body, a cuboid, or other shapes.

[0110] The battery cell includes a shell, an electrode assembly and an electrolyte. The electrode assembly is arranged in the shell, and the electrolyte is filled into the shell through the electrolyte filling port on the shell, so that the electrode assembly is immersed in the electrolyte to produce an electrochemical reaction. The electrode assembly is mainly formed by winding the positive electrode sheet and the negative electrode sheet, and a separator is usually provided between the positive electrode sheet and the negative electrode sheet. The parts of the positive electrode sheet and the negative electrode sheet with active materials constitute the main body of the electrode assembly, and the parts of the positive electrode sheet and the negative electrode sheet without active materials each constitute a pole ear. The positive pole ear and the negative pole ear can be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery cell, the positive active material and the negative active material react with the electrolyte, and the pole ears connect the electrode terminals to form a current loop.

[0111] In the prior art, during the battery production process, electrolyte needs to be injected into the interior of the battery. After the electrolyte injection is completed, residues (electrolyte or electrolyte crystals) will appear on the surface of the battery (near the injection port). In the prior art, the residues are removed by wiping, but the wiping operation is not effective in removing the residues and cannot meet the needs of battery production.

[0112] In the present application, a battery cleaning device is provided, and the driving component of the battery cleaning device is used to drive the suction component, so that the suction head of the suction component switches to the first state. The suction component in the first state sucks the residue on the surface of the battery through the suction head. After the suction is completed, the driving component drives the suction head to switch to the second state to separate the suction head from the battery. The suction head is used to suck out the residue of the battery, thereby reducing the residue on the surface of the battery, so that the battery can be effectively cleaned. In addition, compared with the existing method of wiping the residue, the suction component can significantly improve the removal effect of the residue by the suction component, reducing the battery scrapping or safety problems caused by the battery cleanliness not meeting the standard.

[0113] In the present application, the residue on the battery surface refers to the electrolyte residue that will appear on the surface of the battery after the battery is filled with electrolysis. In addition, the residual electrolyte will produce crystals after a certain period of time. The produced electrolyte crystals need to be dissolved using a DEC (Diethyl carbonate) drip device. Therefore, the residue on the battery surface is usually a mixture of electrolyte and DEC.

[0114] In addition, laser welding equipment is required when sealing the electrolyte filling port of the battery. If the residue on the surface of the battery is not cleaned up to standard, the laser welding equipment will have explosion points at the welding position, thereby reducing the yield rate of the battery.

[0115] In some embodiments of the present application, Figure 1 and Figure 2 As shown, a battery cleaning device 100 includes a driving component 30 and a suction component 40. The suction component 40 includes a suction head 43. The suction head 43 is transmission-connected to the driving component 30. The suction head 43 has a first state and a second state. In the first state, the suction head 43 is driven by the driving component 30 to cooperate with the battery 500. The suction component 40 sucks the residue on the surface of the battery 500 through the suction head 43. In the second state, the suction head 43 is driven by the driving component 30 to be separated from the battery 500.

[0116] In the present application, the cooperation between the suction head 43 and the battery 500 means that the driving component 30 drives the suction head 43 to move towards the direction close to the battery 500 and makes the suction head 43 contact with the battery 500, so that the suction head 43 can form a negative pressure on the surface of the battery 500 when working, thereby utilizing the negative pressure to remove the residue on the surface of the battery 500.

[0117] In addition, in the present application, the transmission connection between the suction head 43 and the drive assembly 30 means that the movement of the suction head 43 is controlled by the drive assembly 30, that is, the suction head 43 can switch between the first state and the second state under the drive of the drive assembly 30. When there is no need to perform suction operation on the battery 500, the drive assembly 30 drives the suction head 43 to remain in the second state, and the suction assembly 40 is in a stopped state. When it is necessary to perform suction operation on the battery 500, the drive assembly 30 drives the suction head 43 to cooperate with the battery 500, and the suction assembly 40 removes the residue on the surface of the battery 500 through the suction head 43.

[0118] During the production process of battery 500, the battery 500 that has been filled with electrolyte usually has residues remaining at the electrolyte filling port of the battery 500. The battery cleaning device 100 is operated, and the driving component 30 drives the suction component 40 so that the suction head 43 of the suction component 40 switches to the first state. The suction component 40 in the first state sucks the residues on the surface of the battery 500 through the suction head 43. After the suction is completed, the driving component 30 drives the suction head 43 to switch to the second state to separate the suction head 43 from the battery 500. The battery cleaning device 100 in the present application utilizes a suction head 43 to remove residues from the battery 500, thereby reducing residues on the surface of the battery 500 so that the battery 500 can be effectively cleaned. In addition, compared with the existing method of wiping residues, the suction operation of the suction component 40 on the residues can significantly improve the removal effect of the residues by the suction component 40, thereby reducing the scrapping of the battery 500 or the occurrence of safety issues due to the battery 500 not meeting the cleanliness standards.

[0119] In the present application, during the production process of the battery 500, the suction component 40 can only perform suction on the electrolyte filling port of the battery 500 through the suction head 43, and the suction component 40 can also perform suction on multiple locations on the surface of the battery 500 through the suction head 43.

[0120] Residues usually appear at the electrolyte filling port of the battery 500. The following is a specific description using the example that the suction component 40 only sucks the electrolyte filling port of the battery 500 and the area around the electrolyte filling port:

[0121] In some embodiments of the present application, Figures 3 to 6 As shown, the suction head 43 includes a first surface 436 and a suction channel 432 having a suction port 431. The first surface 436 is used to face the battery 500. The suction port 431 is opened on the first surface 436. In the first state, the first surface 436 is in contact with the surface of the battery 500, and the residue is received by the suction port 431.

[0122] It should be understood that the first surface 436 and the surface of the battery 500 are in contact with each other, and there may or may not be positive pressure between them. In the present application, there is no positive pressure between the first surface 436 and the surface of the battery 500 to reduce the damage to the battery 500 caused by the suction head 43 squeezing the battery 500.

[0123] In addition, the residue being received by the suction port 431 means that when the first surface 436 and the surface of the battery 500 are in contact with each other, the suction port 431 has a projection area on the surface of the battery 500, and the residue on the surface of the battery 500 is located inside the projection area.

[0124] In addition, the suction port 431 is a port of the suction channel 432, that is, the suction channel 432 is connected to the outside through the suction port 431, and during the suction process, the residue on the surface of the battery 500 enters the suction channel 432 through the suction port 431, so that the residue is separated from the surface of the battery 500, thereby realizing the cleaning operation of the battery 500.

[0125] Specifically, in the present application, the suction head 43 has multiple surfaces, the first surface 436 is one of the multiple surfaces, the first surface 436 is arranged to face the battery 500, and the suction port 431 is opened on the first surface 436. Under the drive of the driving component 30, the suction head 43 switches between the first state and the second state, and the first surface 436 can move in the direction close to or away from the battery 500.

[0126] When the residue on the surface of the battery 500 needs to be removed, the driving component 30 drives the suction head 43 to move toward the battery 500 until the first surface 436 fits the surface of the battery 500 with the residue, and the suction port 431 can cover the residue, and the suction component 40 sucks the residue through the suction port 431 of the suction head 43, so that the residue is sucked away through the suction port 431 to achieve the cleaning operation of the battery 500. After the residue on the surface of the battery 500 is completely removed, the driving component 30 drives the suction head 43 to move away from the battery 500, so that the first surface 436 is separated from the surface of the battery 500.

[0127] The suction port 431 is set on the first surface 436 of the suction head 43, and the first surface 436 is used to fit the surface of the battery 500, and the residue is received by the suction port 431, so that the residue can be completely within the coverage area of ​​the suction port 431, thereby improving the removal effect of the residue, and effectively improving the cleaning effect of the battery 500.

[0128] It should be pointed out that the battery 500 has an electrolyte filling port on its surface with residues, and the shape of the first surface 436 of the suction head 43 is adapted to the shape of the surface of the battery 500 with the electrolyte filling port, thereby improving the fit between the first surface 436 and the surface of the battery 500, and further improving the suction force generated by the suction port 431, thereby significantly improving the effect of the suction component 40 in removing residues on the surface of the battery 500 through the suction head 43.

[0129] In addition, the shape of the suction port 431 includes but is not limited to a circular port, a square port, a triangular port, a trapezoidal port, a diamond port, an elliptical port, etc. In the present application, the shape of the suction port 431 is adapted to the shape of the electrolyte filling port. For example, if the electrolyte filling port is a circular port, the suction port 431 is also a circular port, and the diameter of the suction port 431 is greater than the diameter of the filling port.

[0130] In some embodiments of the present application, Figures 3 to 6 As shown, the suction channel 432 includes a connecting portion 4322 and a cavity portion 4321, the cavity portion 4321 has a first end 43211 and a second end 43212 arranged oppositely, the first end 43211 is connected to the outside through the suction port 431, and the second end 43212 is connected to the connecting portion 4322, and in the direction from the first end 43211 to the second end 43212, the cross-section of the cavity portion 4321 is narrowed.

[0131] In the direction from the first end 43211 to the second end 43212, the cross section of the cavity portion 4321 is narrowed, which means that in the direction perpendicular to the direction from the first end 43211 to the second end 43212, the cavity portion 4321 has a flow cross section, and the cross-sectional area of ​​the flow cross section decreases in the direction from the first end 43211 to the second end 43212. At this time, the cross-sectional area of ​​the flow cross section at the first end 43211 is greater than the area of ​​the flow cross section at the second end 43212.

[0132] In addition, the side wall of the cavity portion 4321 between the first end 43211 and the second end 43212 may be an inclined plane or a concave arc surface.

[0133] It should be understood that the flow cross-sectional area of ​​the first end 43211 of the cavity portion 4321 is greater than the flow cross-sectional area of ​​the second end 43212 of the cavity portion 4321, that is, the first end 43211 is the large end of the cavity portion 4321, and the second end 43212 is the small end of the cavity portion 4321. In addition, the suction port 431 can cover the entire end of the cavity portion 4321, or it can cover a partial end of the cavity portion 4321. In the present application, the suction port 431 covers the entire end of the cavity portion 4321 to increase the connection area between the cavity portion 4321 and the outside world, so that the suction capacity of the suction head 43 is effectively enhanced.

[0134] When the suction component 40 removes the residue through the suction head 43, a negative pressure is generated in the suction channel 432, and the external air flow enters the cavity portion 4321 through the suction port 431 and flows from the first end 43211 of the cavity portion 4321 to the second end 43212, and then enters the connecting portion 4322. Since the cross-section of the cavity portion 4321 is narrowed in the direction from the first end 43211 to the second end 43212, the air flow is compressed in the process of flowing from the first end 43211 to the second end 43212, thereby increasing the flow rate of the air flow and further improving the suction capacity, so that the residue on the surface of the battery 500 can be quickly separated from the battery 500 and enter the cavity portion 4321 through the suction port 431, and then enter the connecting portion 4322 through the cavity portion 4321, so as to enhance the cleaning effect on the battery 500.

[0135] The suction channel 432 is set, and the suction port 431 is set on the first end 43211 of the cavity portion 4321. At the same time, the structure of the cavity portion 4321 is set so that the large mouth of the cavity portion 4321 faces the residue, thereby increasing the suction capacity of the residue on the surface of the battery 500, so that the cleaning effect of the battery 500 can be further improved.

[0136] In some embodiments of the present application, Figures 3 to 6 As shown, a connecting hole 43221 connected to the connecting portion 4322 is provided on the second end 43212, the area of ​​the second end 43212 is larger than the area of ​​the connecting hole 43221, and at least one receiving structure 435 is provided on the second end 43212, and at least one receiving structure 435 is arranged on the outside of the connecting hole 43221.

[0137] Specifically, the communication hole 43221 is provided on the second end 43212 of the cavity portion 4321, and the opening area of ​​the communication hole 43221 is smaller than the area of ​​the second end 43212. The second end 43212 has an area between its edge and the communication hole 43221, and the receiving structure 435 is provided on the edge of the second end 43212 and the area before the communication hole 43221. The receiving structure 435 refers to a structure with receiving capacity, that is, when the residue reaches the position of the receiving structure 435, the residue can be kept at the position of the receiving structure 435, thereby achieving the receiving of the residue.

[0138] When the suction component 40 is sucking the residue on the surface of the battery 500, the residue on the surface of the battery 500 enters the cavity portion 4321 through the suction port 431, a portion enters the connecting portion 4322 through the connecting hole 43221, and the other portion is received by the receiving structure 435. The receiving structure 435 is used to receive the residue, thereby reducing the possibility of the residue falling back to the surface of the battery 500, thereby further improving the cleaning effect of the battery 500.

[0139] It should be understood that the first end 43211 of the cavity 4321 faces the battery 500, and the second end 43212 of the cavity 4321 is located above the first end 43211. The suction assembly 40 sucks the surface of the battery 500 with residues through the suction head 43, and a negative pressure is generated between the suction port 431 and the surface of the battery 500. Under the action of the negative pressure, the residue enters the cavity 4321 through the suction port 431, and the residue entering the cavity 4321 is in liquid state. When the cavity 4321 does not have a receiving structure 435, the liquid residue has a speed and hits the edge of the second end 43212 and the area before the connecting hole 43221. After multiple collisions, the liquid residue will be gathered. Under the action of gravity, the gathered residue will fall off and fall back to the surface of the battery 500 through the suction port 431. In the present application, a receiving structure 435 is provided on the edge of the second end 43212 and the area before the connecting hole 43221. When the residue reaches the position of the receiving structure 435, the liquid residue has a speed and hits the receiving structure 435, and the liquid residue is dispersed. The receiving structure 435 increases the surface area of ​​the second end 43212 and reduces the accumulation of residue, thereby achieving the containment of the residue and reducing the residue from falling back to the surface of the battery 500.

[0140] It should be pointed out that in the present application, the number of the receiving structures 435 can be one or more (two or more). When the number of the receiving structures 435 is multiple, all the receiving structures 435 are arranged at circumferential intervals along the connecting hole 43221 (wherein the spacing can be equal intervals or unequal intervals. In the present application, the spacing is equal intervals, so that the receiving capacity for residues around the connecting hole 43221 can be the same, which can further reduce the situation where the residues fall back to the surface of the battery 500).

[0141] In addition, when there are multiple receiving structures 435, the number of receiving structures 435 can specifically be two, three, four, five, six, etc., wherein the more the number of receiving structures 435 is, the stronger its ability to receive residues is.

[0142] In some embodiments of the present application, Figure 6 As shown, the receiving structure 435 is a protruding structure formed on the second end 43212. The protruding structure is formed on the edge of the second end 43212 and the area before the connecting hole 43221, and the protruding direction is from the second end 43212 to the first end 43211. The protruding structure can increase the surface area of ​​the second end 43212. When the residue reaches the position of the receiving structure 435 with a protruding structure, the liquid residue has a speed and hits the receiving structure 435 with a protruding structure. The liquid residue is dispersed, and the receiving structure 435 with a protruding structure increases the surface area of ​​the second end 43212, reducing the situation of residue gathering, thereby achieving the storage of the residue, reducing the situation of residue falling back to the surface of the battery 500, and further improving the cleaning effect of the battery 500.

[0143] It should be noted that the protrusion structure can be integrally formed with the second end 43212, or can be provided on the second end 43212 by bonding or welding. In the present application, the protrusion structure is integrally formed with the second end 43212, thereby reducing the number of processing steps and reducing the manufacturing cost.

[0144] In some embodiments of the present application, Figure 5As shown, the receiving structure 435 is a concave structure formed on the second end 43212. The concave structure is formed on the edge of the second end 43212 and the area before the connecting hole 43221, and the concave direction is from the first end 43211 to the second end 43212. The concave structure can increase the surface area of ​​the second end 43212. When the residue reaches the position of the receiving structure 435 with a concave structure, the liquid residue has a speed and hits the receiving structure 435 with a concave structure, and the liquid residue is dispersed, and the receiving structure 435 with a concave structure increases the surface area of ​​the second end 43212, reducing the situation of residue gathering, thereby achieving the storage of the residue, reducing the situation of residue falling back to the surface of the battery 500, so that the cleaning effect of the battery 500 is further improved.

[0145] It should be noted that the recessed structure can be integrally formed with the second end 43212, or can be formed on the second end 43212 by cutting or the like. In the present application, the recessed structure is integrally processed with the second end 43212, thereby reducing the processing steps and reducing the manufacturing cost.

[0146] In some embodiments of the present application, the receiving structure 435 is arranged along the radial direction of the connecting hole 43221, and in the radial direction of the connecting hole 43221, the size range of the receiving structure 435 is [1 mm, 3 mm].

[0147] like Figure 4 As shown, Figure 4 Where L3 is the size of the containing structure 435 in the radial direction of the connecting hole 43221. When L3 is less than 1 mm, the size of the containing structure 435 is too small and its ability to contain residues is limited. It is very easy for the residues to fall back to the surface of the battery 500. When L3 is greater than 3 mm, the size of the containing structure 435 is relatively large, which will have an adverse effect (interference, etc.) on other structures such as the connecting hole 43221.

[0148] In the present application, by setting the value of L3 within the range of [1mm, 3mm], it is possible to effectively contain the residues while effectively reducing the adverse effects of the containment structure 435 on other structures.

[0149] It should be pointed out that in the present application, the value of L3 can be 1mm, 1.5mm, 2mm, 2.5mm, or 3mm.

[0150] In some embodiments of the present application, in the circumferential direction of the connecting hole 43221, the size range of the receiving structure 435 is [1 mm, 3 mm].

[0151] like Figure 4 As shown, Figure 4 Where L2 is the size of the containing structure 435 in the circumferential direction of the connecting hole 43221. When L2 is less than 1 mm, the size of the containing structure 435 is too small and its ability to contain residues is limited. It is very easy for the residues to fall back to the surface of the battery 500. When L2 is greater than 3 mm, the size of the containing structure 435 is relatively large, which will have an adverse effect (interference, etc.) on other structures such as the connecting hole 43221.

[0152] In the present application, by setting the value of L2 within the range of [1mm, 3mm], it is possible to effectively contain the residues while effectively reducing the adverse effects of the containment structure 435 on other structures.

[0153] It should be pointed out that in the present application, the value of L2 can be 1mm, 1.5mm, 1.7mm, 2mm, 2.5mm, 2.8mm, or 3mm.

[0154] In some embodiments of the present application, in the axial direction of the connecting hole 43221, the size range of the receiving structure 435 is [1 mm, 3 mm].

[0155] like Figure 5 or Figure 6 As shown, Figure 5 or Figure 6 In the figure, L5 is the size of the containing structure 435 in the axial direction of the connecting hole 43221. When L5 is less than 1 mm, the size of the containing structure 435 is too small and its ability to contain residues is limited. It is very easy for the residues to fall back to the surface of the battery 500. When L5 is greater than 3 mm, the size of the containing structure 435 is relatively large, which will have an adverse effect (interference, etc.) on other structures such as the connecting hole 43221.

[0156] In the present application, by setting the value of L5 within the range of [1mm, 3mm], it is possible to effectively contain the residues while effectively reducing the adverse effects of the containment structure 435 on other structures.

[0157] It should be pointed out that, in the present application, the value of L5 can be 1mm, 1.5mm, 2mm, 2.5mm, or 3mm.

[0158] In some embodiments of the present application, Figures 4 to 6As shown, the suction head 43 also includes a second surface 437, which is connected to the first surface 436 and intersected with the first surface 436. At least one connecting groove 433 is also provided on the first surface 436. In a direction perpendicular to the direction from the first end 43211 to the second end 43212, one end of the connecting groove 433 is connected to the cavity portion 4321, and the other end of the connecting groove 433 is connected to the second surface 437.

[0159] Specifically, the multiple surfaces of the suction head 43 also include a second surface 437, wherein the second surface 437 is connected to the first surface 436, and the first surface 436 and the second surface 437 are arranged to intersect, the suction port 431 is opened on the first surface 436, and a connecting groove 433 is also opened on the first surface 436, and the opening of the connecting groove 433 is arranged to face the battery 500, and the cavity portion 4321 is connected to the second surface 437 through the connecting groove 433.

[0160] Among them, the first surface 436 and the second surface 437 are arranged to intersect, and the angle between the two is A, within the range of 0°<A≤90° (wherein, the angle between the first surface 436 and the second surface 437 is a). In the embodiment of the present application, the first surface 436 and the second surface 437 are arranged vertically, which facilitates processing and reduces processing costs.

[0161] When the suction head 43 is used to remove the residue on the surface of the battery 500, the suction head 43 moves towards the battery 500 under the drive of the driving assembly 30 until the first surface 436 of the suction head 43 is in contact with the surface of the battery 500. The suction assembly 40 operates to form a negative pressure at the position of the suction port 431. Under the action of the negative pressure, the residue can be separated from the surface of the battery 500, thereby achieving the cleaning operation of the battery 500. During the suction process, the connecting groove 433 is connected to the cavity 4321 of the suction head 43, and negative pressure is also generated at the notch position of the connecting groove 433, so that the position on the surface of the battery 500 corresponding to the notch is also sucked, thereby increasing the suction range of the suction head 43 to the battery 500, so that the cleaning effect of the battery 500 is further improved.

[0162] In addition, the connecting groove 433 is connected to the second surface 437 so that air can be replenished inside the cavity 4321 through the connecting groove 433 , thereby reducing the possibility that the suction port 431 causes the electrolyte to be precipitated from the electrolyte filling port of the battery 500 .

[0163] It should be pointed out that in the present application, the number of connecting grooves 433 can be one or more (two or more). When the number of connecting grooves 433 is multiple, all connecting grooves 433 are arranged at circumferential intervals along the suction port 431 (wherein, the spacing can be equal intervals or unequal intervals. In the present application, the spacing is equal intervals, so that the capacity to contain residues around the suction port 431 can be the same).

[0164] In addition, when there are multiple connecting grooves 433, the number of connecting grooves 433 can be two, three, four, five, six, etc., wherein the more connecting grooves 433 there are, the larger the coverage area on the surface of the battery 500 is, thereby further improving the cleaning effect on the battery 500.

[0165] In some embodiments of the present application, in the circumferential direction of the suction port 431 , the size range of the connecting groove 433 is [1 mm, 5 mm].

[0166] like Figure 4 As shown, Figure 4 In the figure, L1 is the size of the receiving structure 435 in the axial direction of the connecting hole 43221. When L1 is less than 1 mm, the size of the connecting groove 433 is too small and the ability to suck the residue is limited. When L1 is greater than 5 mm, the size of the connecting groove 433 is too large, the opening of the receiving groove is too large, and the negative pressure formed at the notch of the receiving groove is reduced, which is not conducive to sucking the residue.

[0167] In the present application, by setting the value of L1 within the range of [1 mm, 5 mm], the removal effect of the residues can be effectively improved.

[0168] It should be pointed out that in the present application, the value of L1 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm.

[0169] In some embodiments of the present application, in the direction from the first end 43211 to the second end 43212 , the size range of the connecting groove 433 is [1 mm, 5 mm].

[0170] like Figure 5 or Figure 6 As shown, Figure 5 or Figure 6 In the figure, L4 is the size of the receiving structure 435 in the axial direction of the connecting hole 43221. When L4 is less than 1 mm, the size of the connecting groove 433 is too small and the ability to suck the residue is limited. When L4 is greater than 5 mm, the size of the connecting groove 433 is too large, the opening of the receiving groove is too large, and the negative pressure formed at the notch of the receiving groove is reduced, which is not conducive to sucking the residue.

[0171] In the present application, by setting the value of L4 within the range of [1 mm, 5 mm], the removal effect of the residues can be effectively improved.

[0172] It should be pointed out that in the present application, the value of L4 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, or 5mm.

[0173] In some embodiments of the present application, Figures 3 to 6 As shown, the suction port 431 is provided with a chamfer 4311 .

[0174] The chamfer 4311 is provided to increase the opening area of ​​the suction port 431 , thereby covering a larger area on the surface of the battery 500 , thereby further improving the cleaning efficiency of the battery 500 .

[0175] A chamfer 4311 is provided at the position of the suction port 431, so that the suction port 431 forms a flared structure. When the airflow mixed with residue enters the cavity portion 4321, the chamfer 4311 can be used to converge the airflow entering the cavity portion 4321, thereby increasing the flow rate of the airflow entering the cavity portion 4321.

[0176] It should be noted that the chamfer 4311 can be a round chamfer or an oblique chamfer.

[0177] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the battery cleaning device 100 further includes a frame 10 , and the driving assembly 30 is adjustably arranged on the frame 10 .

[0178] Specifically, the frame 10 is used to be fixed on a work station of the production system, and the drive assembly 30 is arranged on the frame 10 and can be adjusted relative to the frame 10. By setting the frame 10, the support of the drive assembly 30 and the suction assembly 40 can be achieved. By setting the drive assembly 30 to be adjustable relative to the frame 10, the position of the drive assembly 30 and the suction assembly 40 can be adjusted, and thus it can be effectively applied to the production of the battery 500.

[0179] In the present application, in order to facilitate the adjustment of the position of the driving assembly 30 relative to the frame 10 , an adjustment assembly 20 is provided on the frame 10 , and the driving assembly 30 is connected to the frame 10 via the adjustment assembly 20 .

[0180] In some embodiments of the present application, the adjustment component 20 includes a telescopic member (a telescopic cylinder or a scissor-type bracket, etc.), the fixed end of the telescopic member is connected and fixed to the frame 10, and the free end of the telescopic member is connected to the driving component 30, and the position of the driving component 30 is adjusted by extending or retracting the telescopic member.

[0181] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the battery cleaning device 100 also includes an adjustment component 20, and the adjustment component 20 includes an adjustment seat 21 and an adjustment rod 22. The adjustment seat 21 is rotatably arranged on the frame 10, and a threaded hole is provided on the adjustment seat 21. The adjustment rod 22 is passed through the threaded hole and is threadedly connected to the threaded hole. One end of the adjustment rod 22 protrudes from one side of the threaded hole and is connected to the driving component 30, and the other end of the adjustment rod 22 can protrude from the other side of the threaded hole.

[0182] Specifically, the adjustment seat 21 is mounted on the frame 10 and can rotate relative to the frame 10, the adjustment rod 22 is threadedly connected to the threaded hole of the adjustment seat 21, and one end of the adjustment rod 22 is connected to the driving assembly 30. When the position of the driving assembly 30 needs to be adjusted, a tool is used to cooperate with the adjustment seat 21, and the adjustment seat 21 is rotated relative to the frame 10 by driving the tool. The rotation of the adjustment seat 21 can drive the adjustment to move along its axial direction, thereby realizing the adjustment of the position of the driving assembly 30.

[0183] The drive assembly 30 is connected to the frame 10 through the adjustment assembly 20. The adjustment assembly 20 has a simple structure and can effectively reduce the manufacturing cost. At the same time, the adjustment of the drive assembly 30 by the adjustment assembly 20 is easy to operate and can effectively improve the convenience during use.

[0184] It should be pointed out that the adjustment seat 21 and the adjustment rod 22 are threadedly connected, and the position is adjusted by relative rotation. The threaded connection has a stable structure and high strength, and can effectively maintain the adjusted position. In addition, the threaded adjustment has high accuracy, which can effectively improve the accuracy of the position adjustment of the drive assembly 30.

[0192] In some embodiments of the present application, Figure 1 and Figure 2As shown, the driving mechanism 32 also includes a fixed seat 321 and a driving member 34 . The fixed seat 321 is connected to the connecting seat 31 . The movable seat 322 is slidably arranged on the fixed seat 321 . The driving member 34 is installed on the fixed seat 321 and is transmission-connected to the movable seat 322 .

[0193] Specifically, the fixed seat 321 refers to a component that remains stationary during operation, and the movable seat 322 refers to a component that can move during operation. The movable seat 322 is disposed on the fixed seat 321 and can slide relative to the fixed seat 321. A driving mechanism 32 is disposed between the two, and the driving mechanism drives the movable seat 322 to move relative to the fixed seat 321.

[0194] In the present application, the movable seat 322 is slidably arranged on the fixed seat 321 and is controlled by the driving member 34.

[0199] By setting the type of the driving member 34 , the driving member 34 can be set according to different usage requirements, thereby effectively meeting the actual production needs, so that the production efficiency of the battery 500 is effectively improved.

[0200] In some embodiments of the present application, Figure 1 and Figure 2As shown, the driving mechanism 32 also includes a buffer member 323, and the buffer member 323 includes a buffer portion 3232 and a limit portion 3231. One of the movable seat 322 and the fixed seat 321 is provided with the buffer portion 3232, and the other of the movable seat 322 and the fixed seat 321 is provided with the limit portion 3231. In the first state, the buffer portion 3232 abuts against the limit portion 3231, and the buffer portion 3232 has a rebound force, and the rebound force is used to drive the suction head 43 to switch to the second state. In the second state, the buffer portion 3232 is separated from the limit portion 3231.

[0201] It should be understood that the buffer portion 3232 has buffering properties. One of the limiting portion 3231 and the buffer portion 3232 is installed on the fixed seat 321, and the other is installed on the movable seat 322. When the suction head 43 moves toward the battery 500, the movable seat 322 moves relative to the fixed seat 321. When the suction head 43 is in contact with the battery 500, the buffer portion 3232 abuts against the limiting portion 3231. The limiting portion 3231 applies a force to the buffer portion 3232 to prevent the suction head 43 from moving toward the battery 500 again.

[0202] A buffer member 323 is provided to buffer the movable seat 322, thereby reducing the collision between the suction head 43 and the surface of the battery 500 when switching to the first state, reducing damage to the battery 500, and effectively improving the reliability of the battery cleaning device 100.

[0203] In some embodiments of the present application, the buffer portion 3232 includes rubber, a spring, a gas pressure rod or an oil pressure rod.

[0204] By setting the type of the buffer portion 3232 of the buffer member 323 , the buffer portion 3232 can be set according to different usage requirements, thereby effectively meeting the needs of actual production, so that the production efficiency of the battery 500 is effectively improved.

[0205] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the connecting mechanism 33 includes a first mounting seat 331, a second mounting seat 333 and at least two connecting columns 332, the first mounting seat 331 is connected to the movable seat 322, the suction head 43 is installed on the second mounting seat 333, and the second mounting seat 333 is connected to the first mounting seat 331 through at least two connecting columns 332.

[0206] Specifically, the first mounting seat 331 is connected to the movable seat 322 of the driving structure, and the second mounting seat 333 is spaced apart from the first mounting seat 331, and the two are connected by a connecting column 332. The connecting column 332 is used to improve the installation accuracy of the second mounting seat 333 relative to the first mounting seat 331, so as to improve the installation accuracy of the suction head 43 installed on the second mounting seat 333, thereby reducing the situation where the suction effect of the residue is poor or the collision with the battery 500 is caused by the poor installation position of the suction head 43.

[0207] It should be pointed out that the first mounting seat 331 and the second mounting seat 333 are arranged in parallel and spaced apart from each other, one end of the connecting column 332 is connected to the first mounting seat 331 (the connection method includes but is not limited to threaded connection, welding or clamping, etc.), and the other end of the connecting column 332 is connected to the second mounting seat 333 (the connection method includes but is not limited to threaded connection, welding or clamping, etc.), and at least two connecting columns 332 are arranged in parallel and spaced apart. Utilizing the connecting column 332 can improve the positional accuracy between the first mounting seat 331 and the second mounting seat 333.

[0208] In the present application, a connection structure 434 is provided on the suction head 43, and is connected and fixed to the second mounting seat 333 through the connection structure 434, wherein the connection structure 434 includes but is not limited to a connection hole, a connection column or a connection slot, etc.

[0209] In addition, in the present application, the connecting column 332 includes but is not limited to a stud or a positioning column.

[0210] In addition, in the present application, the number of the connecting pillars 332 can be two, three, four, five, six, seven or eight, etc.

[0211] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the suction component 40 also includes a suction piece, a joint 41 and a connecting pipe 42. The suction piece is used to provide suction negative pressure. The joint 41 is installed on the first mounting seat 331 and is connected to the suction piece. One end of the connecting pipe 42 is connected to the joint 41, and the other end of the connecting pipe 42 is connected to the suction head 43.

[0212] The suction component 40 has a simple structure and low manufacturing cost, which can effectively reduce the manufacturing cost of the battery cleaning device 100. In addition, the structural setting of the suction component 40 can be driven by the driving component 30 to move toward or away from the battery 500, thereby achieving the operation of the suction head 43 adhering to the surface of the battery 500 and sucking out the residue, and improving the cleaning effect on the surface of the battery 500.

[0213] It should be noted that, in the present application, the suction member is a vacuum pump or the like.

[0214] In some embodiments of the present application, Figure 7 As shown, the battery cleaning device 100 further includes a detection component 50 and a control component 60. The detection component 50 is used to detect the position of the battery 500, and the control component 60 is electrically connected to the driving component 30, the suction component 40 and the detection component 50 respectively.

[0215] By detecting the position of the battery 500 through the detection component 50 and controlling the driving component 30 and the suction component 40 through the control component 60, the residue on the surface of the battery 500 can be accurately removed, so that the cleaning effect of the battery 500 is further improved.

[0216] It should be noted that the detection component 50 includes but is not limited to a photoelectric switch or a contact switch, etc. In addition, the control component 60 includes a PLC control module.

[0217] like Figure 8 As shown, the present application also proposes a battery production system 1000, which includes a conveying device 200 and a battery cleaning device 100 as described above, wherein the conveying device 200 is used to convey the battery 500, and the battery cleaning device 100 is arranged on at least one side of the conveying device 200 and can clean the residue on the surface of the passing battery 500.

[0218] During the production process of battery 500, the battery 500 that has been filled with electrolyte usually has residues remaining at the electrolyte filling port of the battery 500. The conveying device 200 conveys the battery 500 that has been filled with electrolyte to the position of the battery cleaning device 100, and the battery cleaning device 100 is operated. The driving component 30 drives the suction component 40 so that the suction head 43 of the suction component 40 switches to the first state. The suction component 40 in the first state sucks the residues on the surface of the battery 500 through the suction head 43. After the suction is completed, the driving component 30 drives the suction head 43 to switch to the second state to separate the suction head 43 from the battery 500. The battery cleaning device 100 in the present application utilizes a suction head 43 to remove residues from the battery 500, thereby reducing residues on the surface of the battery 500 so that the battery 500 can be effectively cleaned. In addition, compared with the existing method of wiping residues, the suction operation of the suction component 40 on the residues can significantly improve the removal effect of the residues by the suction component 40, thereby reducing the scrapping of the battery 500 or the occurrence of safety issues due to the battery 500 not meeting the cleanliness standards.

[0219] In some embodiments of the present application, the battery production system 1000 also includes a liquid injection device 300 and a wiping device 400. The liquid injection device 300 is arranged on at least one side of the conveying device 200 and is located at an electrolyte filling station upstream of the battery cleaning device 100. The liquid injection device 300 is used to inject electrolyte into the interior of the passing battery 500. The wiping device 400 is arranged on at least one side of the conveying device 200 and is located at a wiping station downstream of the battery cleaning device 100. The wiping device 400 is used to wipe the battery 500 after being cleaned by the battery cleaning device 100.

[0220] The electrolyte is added to the battery 500 using the injection device 300, and the residue on the surface of the battery 500 is sucked out using the cleaning device. Finally, the surface of the battery 500 is wiped using the wiping device 400, so that the cleanliness of the surface of the battery 500 meets the production requirements.

[0221] It should be pointed out that the wiping device 400 includes a wiping head (flexible and hygroscopic component) and a driving component. The driving component drives the wiping head to contact the surface of the battery 500. At the same time, the driving component 30 also drives the wiping head to move relative to the surface of the battery 500. The movement of the wiping head relative to the surface of the battery 500 is utilized to realize the wiping operation on the surface of the battery 500, so that the cleanliness of the surface of the battery 500 meets the production requirements.

[0222] like Fig. 9 As shown, the third aspect of the present application proposes a battery 500 processing method, which is implemented by the above-mentioned battery production system 1000, and the battery 500 processing method includes S1: controlling the conveying device 200 to convey the battery 500 that is not filled with electrolyte to the electrolyte filling station, S2: controlling the injection device 300 to fill the battery 500 with electrolyte, S3: according to the completion of the electrolyte filling of the battery 500, controlling the conveying device 200 to convey the battery 500 to the cleaning station, S4: controlling the battery cleaning device 100 to absorb the residue on the battery 500, S5: according to the completion of the residue absorption on the battery 500, controlling the conveying device 200 to convey the battery 500 to the wiping station, S6: controlling the wiping device 400 to wipe the surface of the battery 500.

[0223] During the production process of battery 500, the battery 500 is first filled with electrolyte using the injection device 300, and then the residue on the surface of the battery 500 is sucked out using the cleaning device, and finally the surface of the battery 500 is wiped using the wiping device 400. Through the combined action of the battery cleaning device 100 and the wiping device 400, the cleaning effect of the battery 500 is improved, so that the cleanliness of the surface of the battery 500 meets the production requirements.

[0224] In some embodiments of the present application, in the step of controlling the battery cleaning device 100 to remove residues on the battery 500 , the suction vacuum degree of the battery cleaning device 100 is X, wherein -60 kpa≤X≤-30 kpa.

[0225] It should be noted that when X is greater than -30 kPa, the effect of removing the residue on the surface of the battery 500 becomes poor, and when X is less than -60 kPa, the electrolyte inside the battery 500 is easily sucked out from the electrolyte filling port. By setting X to -60 kPa≤X≤-30 kPa, while taking into account the effect of removing the residue from the battery 500, the situation of the electrolyte inside the battery 500 being sucked out is effectively reduced.

[0226] In addition, the value of X can be -30kpa, -35kpa, -40kpa, -45kpa, -50kpa, -55kpa, and -60kpa.

[0227] In some embodiments of the present application, in the step of controlling the battery cleaning device 100 to remove the residue on the battery 500, the duration of the battery cleaning device 100 removing the residue on the battery 500 is t, wherein 2s≤t≤6s.

[0228] It should be noted that when t is less than 2s, the removal effect of the residue on the surface of the battery 500 is poor, and when t is greater than 6s, the electrolyte inside the battery 500 is easily sucked out from the electrolyte filling port and energy consumption is increased. By setting t to 2s≤t≤6s, while taking into account the effect of removing the residue from the battery 500, the situation of the electrolyte inside the battery 500 being sucked out is effectively reduced, and the energy consumption during the production process of the battery 500 is reduced.

[0229] In addition, the value of t can be 2s, 2.5s, 3s, 3.5s, 4s, 4.5s, 5s, 5.5s, and 6s.

[0230] In some embodiments of the present application, in the step of controlling the battery cleaning device 100 to remove the residue on the battery 500, the temperature at which the battery cleaning device 100 removes the residue on the battery 500 is T, wherein 20°C≤T≤25°C.

[0231] It should be noted that when T is less than 20°C, the temperature is low, the fluidity of the liquid residue is poor, and the effect of removing the residue on the surface of the battery 500 becomes poor. When T is greater than 25°C, the fluidity of the liquid residue is good, and the liquid residue is likely to flow to other locations of the battery 500. By setting T to 20°C≤T≤25°C, the effect of removing the residue is further improved.

[0232] In addition, the value of X can be -30kpa, -35kpa, -40kpa, -45kpa, -50kpa, -55kpa, and -60kpa.

[0233] By setting the motion parameters of the battery cleaning device 100, the cleaning effect of the battery cleaning device 100 on the surface of the battery 500 is effectively improved, so that the battery 500 can meet production needs and reduce the scrapping of the battery 500 or safety problems caused by the battery 500 not meeting the cleanliness standards.
