[0028] according to Figure 1-4As shown, this embodiment provides a lithium battery filling port cleaning device, including a moving device 10 and a sensing and control device. Above the moving device 10, along the moving direction of the moving device 10, a spraying assembly 21, a wiping assembly 22, and an air blowing assembly 23 are sequentially fixed. The sensing and control device includes a photoelectric sensor 31 and a blocking cylinder 32. The photoelectric sensor 31 and the blocking cylinder 32 are connected through a PLC. The photoelectric sensor 31 is fixed to the side of the moving device 10. The spraying assembly 21, the wiping assembly 22, and the air blowing assembly 23 are all fixed to the blocking cylinder 32.

[0029] like Figure 1 As shown, three photoelectric sensors 31 are arranged on the side of the mobile device 10. They are all fixed to the side of the mobile device 10 by mounting pieces (not shown in the figure). The three photoelectric sensors 31 are respectively fixed next to the spraying assembly 21, the wiping assembly 22 and the blowing assembly 23. The three photoelectric sensors 31 cooperate with the blocking cylinders 32 fixed to the spraying assembly 21, the wiping assembly 22 and the blowing assembly 23. When the lithium battery comes to the corresponding position, the photoelectric sensor 31 senses it and transmits the signal to the blocking cylinder 32 through the PLC. The blocking cylinder 32 fixes and positions the lithium battery.

[0030] The moving surface of the mobile device 10 is provided with a guide component. In this embodiment, the guide component is a guide roller 11. In this embodiment, there are 5 guide rollers 11, which are placed side by side on the moving surface of the mobile device 10. They are placed on the moving surface of the mobile device 10 by fixing brackets 12. In this embodiment, the guide rollers 11 are fixed by 4 fixing brackets 12, so that the lithium battery moves between the guide rollers 11. This has a positioning function for the movement of the lithium battery and is beneficial for cleaning the electrolyte filling port of the lithium battery.

[0031] like Figure 2 As shown, the spraying assembly 21 includes a mounting frame 24, which includes side plates 241 and a horizontal plate 242. The side plates 241 are trapezoidal in shape, and the horizontal plate 242 is rectangular in shape. The bottom edges of the side plates 241 are fixed to both sides of the moving device 10. The two side plates 241 are connected by the horizontal plate 242 to form the mounting frame 24. The horizontal plate 242 is fixed to the blocking cylinder 32 by a right-angle plate (not shown in the figure). The telescopic end of the blocking cylinder 32 passes through the right-angle plate and is connected to the baffle 321 through a floating joint 323. The surface of the baffle 321 is provided with a PU block 322. By setting the floating joint 323 and the PU block 321, a certain shock absorption effect can be provided for the contacting lithium battery, reducing damage to the lithium battery.

[0032] In this embodiment, the spraying assembly 21 is equipped with four blocking cylinders 32. The telescopic ends of these four cylinders extend outwards, and baffles 321 can fix and position multiple lithium batteries, allowing simultaneous spraying of liquid into the filling ports of multiple lithium batteries. In this embodiment, a first telescopic cylinder 213 is fixed between two blocking cylinders 32. The telescopic end of the first telescopic cylinder 213 is connected to a spraying valve 211 via a mounting plate 212. The mounting plate 212 fixes two spraying valves 211. The blocking cylinders 32 and the first telescopic cylinder 213 are connected via a PLC. After the blocking cylinders 32 fix and position the lithium batteries, the PLC transmits a signal to the first telescopic cylinder 213. At this time, the first telescopic cylinder 213 extends towards the filling port of the lithium batteries, enabling the spraying valve 211 to spray alcohol or DMC solution onto the filling port, melting the electrolytic liquid crystal at the filling port for further cleaning.

[0033] like Figure 3 As shown, the wiping assembly 22 includes a bracket 25 and a movable frame 26. One end of the bracket 25 is fixed to the side of the movable device 10, and the other end of the bracket 25 is connected to the blocking cylinder 32. The telescopic end of the blocking cylinder 32 is connected to the movable frame 26. One end of the movable frame 26 is provided with a guide rod 27. The guide rod 27 is connected to the movable frame 26 through an oil-free bushing. The movable frame 26 can move up and down along the guide rod 27. The bottom of the movable frame 26 is provided with a stop bar 261. The stop bar 261 is used to fix and position multiple lithium batteries. In this embodiment, the telescopic end of the blocking cylinder 32 extends downward, so that the movable frame 26 moves downward along the guide rod 27. At this time, the stop bar 261 can fix and position multiple lithium batteries.

[0034] The wiping assembly 22 has a rotating component on the movable frame 26. The rotating component includes a motor 224, which is fixed to the end of the movable frame 26 and connected to the shaft 223 via a coupling 222. One end of the bevel gear set 225 is sleeved on the shaft 223, and the other end is connected to the brush 221. The other end of the shaft 223 is fixed using a bearing seat 227. In this embodiment, the motor 224 drives the shaft 223 to rotate, and the shaft 223 drives the bevel gear set 225 to rotate, thereby driving the liquid injection port of the brush 221 to rotate, so as to wipe away the electrolyte melted at the liquid injection port.

[0035] like Figure 4As shown, the air blowing assembly 23 includes a mounting frame 24, which includes a side plate 241 and a horizontal plate 242. The side plate 241 is trapezoidal in shape, and the horizontal plate 242 is rectangular in shape. The bottom edge of the side plate 241 is fixed to both sides of the moving device 10. The two side plates 241 are connected by the horizontal plate 242 to form the mounting frame 24. The horizontal plate 242 is fixed to the blocking cylinder 32 by a right-angle plate (not shown in the figure). The telescopic end of the blocking cylinder 32 passes through the right-angle plate and is connected to the baffle 321 through a floating joint 323. The surface of the baffle 321 is provided with a PU block 322. By setting the floating joint 323 and the PU block 321, a certain shock absorption effect can be provided for the contacting lithium battery, reducing damage to the lithium battery.

[0036] The air blowing assembly 23 is equipped with two blocking cylinders 32. The telescopic ends of the two blocking cylinders 32 extend outwards, and multiple lithium batteries can be fixed and positioned via baffles 321, allowing simultaneous cleaning of the electrolyte filling ports of multiple lithium batteries. In this embodiment, a second telescopic cylinder 231 is fixed between the two blocking cylinders 32. The telescopic end of the second telescopic cylinder 231 is connected to an air blowing plate 232. The air blowing plate 232 has four air blowing nozzles 233 evenly distributed at its bottom, and two air source connectors 234 at its top. The air passages inside the air blowing plate 232 are interconnected. The blocking cylinders 32 and the second telescopic cylinder 231 are connected via a PLC. After the blocking cylinders 32 fix and position the lithium batteries, in this embodiment, the air source is connected via the air source connectors 234, and then the air blowing nozzles 233 are used to blow clean the lithium battery electrolyte filling ports.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
