In the production process of lithium batteries, liquid injection is a very important process, and the ability of the liquid injection process directly affects the yield of lithium batteries.

[0003] Currently, electrolyte is injected into the battery by a liquid injection machine. After each injection is completed, electrolyte remains at the bottom of the injection cup and the liquid injection nozzle. Before injecting the next battery, the remaining electrolyte will drip onto the machine table, polluting the working environment. The electrolyte remaining outside the liquid injection nozzle will form crystals, which can adversely affect the processing of subsequent batteries and affect the yield of the battery.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0042] Reference Figures 1-10This application provides a battery filler nozzle cleaning device 100, which includes: a base frame assembly 110, a rotational kinetic energy assembly 120 and a cleaning assembly 130 disposed on the base frame assembly 110. The rotational kinetic energy assembly 120 drives the cleaning assembly 130 to rotate. The cleaning assembly 130 includes a housing assembly 135, and a bristle cleaning block 131 and a rotating cleaning block 132 fixedly connected within the housing assembly 135. The rotating cleaning block 132 is cylindrical, with a first passage 1321 vertically arranged at its center and a recessed first O-shaped groove 1322 horizontally arranged around its perimeter. The upper opening of the first passage 1321 is larger than that of the bristle cleaning block 131, for accommodating the bristle cleaning block 131. The other end (lower end) of the first passage 1321 has a cleaning fluid outlet. The first O-shaped groove 1322 communicates with the first passage 1321 and the outside of the cleaning assembly 130, for introducing external gas and liquid into the first passage 1321. The brush cleaning block includes a brush body 1312 and brush bristles 1311. As shown in the figure, the brush cleaning block 131 and the rotating cleaning block 132 can be fixed together by fasteners. For example, a first fixing hole 1314 is provided on the brush body 1312, and a second fixing hole 135 is provided at a corresponding location on the rotating cleaning block 132. Fasteners such as bolts pass through the first fixing hole 1314 and are fixed to the second fixing hole 135, thus fixing the brush cleaning block 131 and the rotating cleaning block 132 together. The brush cleaning block has a contoured structure of an injection nozzle 200 and is provided with at least one strip-shaped through hole 1313. In this embodiment, the brush cleaning block has three strip-shaped through holes 1313. (Reference) Figures 7-9 Three strip-shaped through holes 1313 are evenly distributed on the brush body 1312 of the bristle cleaning block. The three strip-shaped through holes 1313 communicate with the first passage 1321. Bristles 1311 are provided on the side of the bristle cleaning block that contacts the injection nozzle. The bristles 1311 can be made of materials such as PBT, and the brush body 1312 can be made of aluminum. The manufacturing process of the bristle cleaning block can be as follows: first, a contoured aluminum brush body 1312 is made; then, bristles are implanted onto the brush body 1312, and the bristles 1311 are implanted on the side of the brush body 1312 that contacts the injection nozzle. The bristle cleaning block is used to accommodate the injection nozzle and to rotate and clean it. The battery nozzle cleaning device 100 provided in this application, through the structural arrangement of the rotating cleaning block 132 and the bristle cleaning block 131, houses the nozzle in the bristle cleaning block 131 and cleans it by rotating the bristles 1311. Actual testing has shown that it effectively cleans the nozzle and has a very good cleaning effect. At the same time, the contoured structure of the bristle cleaning block 131 can effectively prevent the cleaning fluid from splashing.

[0043] In the embodiment, the rotating cleaning block 132 is provided with three second passages 1323 with different angles with the horizontal plane, and the three second passages 1323 respectively communicate the first O-shaped groove 1322 with the first passage 1321. The angle between the second passage 1323 and the horizontal direction H-H' is α, the angles between the three second passages 1323 and the horizontal plane are α1, α2 and α3 respectively, α1< α2< α3, and α1≥ 0°. When the battery liquid injection nozzle cleaning device 100 is cleaning the liquid injection nozzle, the external cleaning liquid flows to the first passage 1321 through the second passage 1323 from the external gas-liquid inlet, and the bristle cleaning block is soaked. In this way, the second passages 1323 with different angles can ensure the flow and soaking effect of the cleaning liquid. In addition, when the external dry gas flows to the first passage 1321 through the second passage 1323 from the external gas-liquid inlet, the residual cleaning liquid is blown dry, and the second passages 1323 with different angles can more thoroughly blow away the residual cleaning liquid, avoiding the crystallization or pollution of the residual cleaning liquid to the subsequent process.

[0044] In the embodiment, one end of the three second passages 1323 communicates with the first O-shaped groove 1322, and the other end respectively communicates with the upper, middle or lower part of the strip-shaped through hole 1313 of the bristle cleaning block 131. Figure 6 As shown in the figure, the second passage 1323-1 communicates with the lower part of the strip-shaped through hole 1313 of the bristle cleaning block 131, the second passage 1323-2 communicates with the middle part of the strip-shaped through hole 1313 of the bristle cleaning block 131, and the second passage 1323-3 communicates with the upper part of the strip-shaped through hole 1313 of the bristle cleaning block 131. In this way, by setting the second passages 1323 with different angles, the efficiency of the external cleaning liquid or dry air passing into the bristle cleaning block 131 can be more effectively guaranteed, and the effect of cleaning the liquid injection nozzle can be improved. Alternatively or preferably, the angle α1 between the second passage 1323-1 and the horizontal direction can be 0°-10°, the angle α2 between the second passage 1323-2 and the horizontal plane can be 10°-25°, and the angle α3 between the second passage 1323-3 and the horizontal plane can be 25°-45°. Such angle setting can better play the cleaning and drying effect of the external cleaning liquid and dry air, and further avoid the influence of the crystallization of the residual cleaning liquid on the subsequent process.

[0045] In this embodiment, the rotating cleaning block 132 is further provided with two second O-ring grooves 1324. The two second O-ring grooves 1324 are respectively disposed on both sides of the first O-ring groove 1322 in the vertical direction, and O-rings 133 are fitted inside the two second O-ring grooves 1324. The O-ring 133 is a rubber sealing ring with a circular cross-section. Because its cross-section is O-shaped, it is called an O-ring 133 or an O-ring rubber sealing ring. By providing second O-ring grooves 1324 on both sides of the first O-ring groove 1322 and placing O-rings 133 inside the O-ring grooves, the rotating cleaning block 132 can be effectively sealed, preventing leakage of the rotating cleaning block 132.

[0046] In this embodiment, the rotating cleaning block 132 is also provided with an oil seal 134. For example... Figure 4 As shown, the oil seal 134 is fitted onto the two vertically spaced sides of the two second O-ring grooves 1324 of the rotating cleaning block 132. The oil seal has a simple structure and is easy to manufacture; it is lightweight, requires less material, has a small installation space, small axial dimensions, is easy to process, and makes the machine compact; it has good sealing performance and a long service life; it is easy to disassemble and inspect, and is also inexpensive. By setting the oil seal 134 between the rotating cleaning block 132 and the housing assembly 135, the sealing performance of the battery filling nozzle cleaning device 100 can be further guaranteed.

[0047] In this embodiment, the housing assembly 135 is provided with an external liquid inlet 1351 and an external gas inlet 1352. The external liquid inlet 1351 and the external gas inlet 1352 are respectively connected to the first O-ring 1322. The battery filler nozzle cleaning device 100 also includes a drying air blowing assembly 160 and a cleaning fluid inflow assembly 150. The external liquid inlet 1351 connects the drying air blowing assembly 160 to the cleaning assembly 130, and the external gas inlet 1352 connects the cleaning fluid inflow assembly 150 to the cleaning assembly 130. In this embodiment, the housing assembly 135 also includes a splash guard 1353. The splash cover 1353 is fixed above the bristle cleaning block 131 to further reduce the gap between the bristle cleaning block 131 and the injection nozzle 200. The diameter of the splash cover 1353 is slightly larger than the outer diameter of the injection nozzle. After the injection nozzle is immersed in the bristle cleaning block, the flange 201 of the injection nozzle 200 completely covers the opening of the splash cover 1353 that accommodates the injection nozzle 200, thus further preventing the cleaning fluid from splashing during cleaning.

[0048] In the embodiment, the 110-base frame assembly includes the first base plate 111, the second base plate 112 and the third base plate 113 fixed to each other from bottom to top. The rotating kinetic energy assembly 120 includes a rotating motor 121 and a transmission assembly. The transmission assembly includes a shaft coupling 122, a driving shaft 123, two synchronous pulleys (124 / 125) and a transmission belt 126. Among them, the rotating motor 121 is fixed to the third base plate 113, the driving shaft 123 is fixed to the second base plate 112, and the rotating cleaning block 132 is fixed to the second base plate 112 through a ball bearing. The shaft coupling 122 fixedly connects the driving shaft 123 and the rotating shaft of the rotating motor 121, and the two synchronous pulleys are respectively installed on the driving shaft 123 and the rotating cleaning block 132 and are connected by the transmission belt 126. The transmission assembly can transmit the kinetic energy of the rotating motor 121 in the rotating kinetic energy assembly 120 to the rotating cleaning block 132, so as to ensure the stability of the rotation of the rotating cleaning block 132. In the embodiment, the cleaning assembly 130 further includes a bearing, which is sleeved on the outer wall between the synchronous pulley 124 of the rotating cleaning block 132 and the bristle cleaning block. Through the setting of the bearing, the stability of the rotation of the rotating cleaning block 132 can be further ensured.

[0049] In the embodiment, the battery liquid injection nozzle cleaning device 100 further includes a residual liquid receiving assembly 140. The residual liquid receiving assembly 140 is fixed to the first base plate 111. The residual liquid receiving assembly 140 includes a guide groove 141 and a third passage 142. Among them, the guide groove 141 is arranged along the vertical direction. The third passage 142 is arranged along the horizontal direction. The guide groove 141 is arranged above the third passage 142, one end of which is in communication with the first passage 1321, and the other end is connected with the third passage 142. Through the setting of the residual liquid receiving assembly 140, the flow direction of the residual liquid cleaning liquid can be effectively guided, and the collection and treatment of the waste liquid can be facilitated.

[0050] In the embodiment, the third passage 142 has a certain slope with the horizontal plane, that is, the height of the residual liquid outlet end 1421 of the third passage 142 along the horizontal direction is lower than that of the other end. The angle between the third passage 142 and the horizontal direction H-H' is β, and β>0°. Alternatively or preferably, the range of β can be: 0°<β<15°. In this way, the flow direction of the residual liquid cleaning liquid can be more effectively guided, and the residual cleaning liquid and the dead volume in the battery liquid injection nozzle cleaning device 100 can be reduced. In the embodiment, the battery liquid injection nozzle cleaning device 100 includes two sets of rotating kinetic energy assemblies 120 and cleaning assemblies 130, and the corresponding residual liquid receiving assembly 140 includes two guide grooves 141, that is, the guide groove 141 and the guide groove 141', the residual liquid outlet end 1421 of the third passage 142 is close to the guide groove 141', and the height of the connection between the third passage 142 and the guide groove 141 is higher than that of the connection between the third passage 142 and the guide groove 141'. In this way, the cleaning liquid after being cleaned by the two sets of cleaning assemblies 130 can be conveniently guided out.

[0051] Another aspect of the present application provides a battery manufacturing equipment comprising the battery liquid injection nozzle cleaning device. The battery manufacturing equipment further comprises a battery liquid injection device.
