The output end of the first driving cylinder 31 is directly or indirectly connected to the sliding mounting plate 4 and can drive the sliding mounting plate 4 to slide on the lifting guide column 2. In this embodiment, the output end of the first driving cylinder 31 is indirectly connected to the sliding mounting plate 4. In some other embodiments, if necessary, the output end of the first driving cylinder 31 can also be directly connected to the sliding mounting plate 4. The second driving cylinder 32 and the third driving cylinder 33 are fixedly mounted on the sliding mounting plate 4, and the sliding mounting plate 4 is also movably mounted with a cleaning sleeve 51, and a blocking rod 52 is arranged inside the cleaning sleeve 51 and passes through it from top to bottom, the output end of the second driving cylinder 32 is connected to the cleaning sleeve 51 and can drive the cleaning sleeve 51 to move up and down, the output end of the third driving cylinder 33 is connected to the upper end of the blocking rod 52 and can drive the blocking rod 52 to move up and down inside the cleaning sleeve 51, an inner gap 53 is provided between the inner wall of the cleaning sleeve 51 and the outer wall of the blocking rod 52, an air inlet hole 511 connected to the inner gap 53 is provided at the upper end of the cleaning sleeve 51, an air blowing hole 512 connected to the inner gap 53 is provided at the lower end of the cleaning sleeve 51, the lower end of the blocking rod 52 passes through the lower end of the cleaning sleeve 51 and a sealing rubber head 521 is provided at the passing end. It also includes a matching fixture assembly 8, wherein a liquid injection cup 9 is arranged inside the fixture assembly 8, and a liquid injection port is provided at the lower end of the liquid injection cup 9. The blocking rod 52 can block the liquid injection port through the sealing rubber head 521, and the blowing hole 512 can blow high-pressure gas into the inner wall of the liquid injection cup 9 to achieve a cleaning function.

[0028] In actual implementation, the cleaning sleeve 51 is a stainless steel sleeve, the blocking rod 52 is a stainless steel blocking rod, and the cleaning sleeve 51 and the blocking rod 52 together form a rod-in-rod structure.

[0029] In this embodiment, the second driving cylinder 32 is directly mounted on the sliding mounting plate 4, the third driving cylinder 33 is fixed to the side of the cylinder body of the second driving cylinder 32 and is indirectly mounted on the sliding mounting plate 4 through the second driving cylinder 32, and the output end of the first driving cylinder 31 is fixedly connected to the end of the second driving cylinder 32 and is indirectly connected to the sliding mounting plate 4 through the second driving cylinder 32.

[0030] During use, after the battery inside the jig assembly 8 is filled with liquid, and the cover disassembly robot removes the cover of the jig assembly 8, some electrolyte remains on the inner wall of the liquid filling cup 9 inside the jig assembly 8 and needs to be cleaned.

[0031] At this time, the first driving cylinder 31 drives the sliding mounting plate 4 and the second driving cylinder 32, the third driving cylinder 33 and other components arranged on the sliding mounting plate 4 to descend, and simultaneously drives the cleaning sleeve 51 and the blocking rod 52 to descend, so that the lower ends of the cleaning sleeve and the blocking rod 52 enter the interior of the liquid filling cup 9; further, the third driving cylinder 33 drives the blocking rod 52 to continue to descend, so that the sealing rubber head 521 blocks the liquid filling nozzle of the liquid filling cup 9. After the liquid filling nozzle of the liquid filling cup 9 is blocked, the residual electrolyte in the liquid filling cup 9 will not flow out from the liquid filling nozzle. At this time, the battery that has completed the injection will be taken away by the hook mechanism of the unloading section of the next process.

The blown air acts on the inner wall of the injection cup 9, so that the electrolyte on the inner wall of the injection cup 9 is blown downward and finally flows into the electrolyte recovery pipeline through the injection nozzle. At the same time, the electrolyte recovery pipeline can provide a suction force to further improve the cleaning quality.

[0033] In the process of cleaning the liquid injection cup 9 by blowing air through the blowing hole 512 , the second driving cylinder 32 drives the cleaning sleeve 51 to slowly descend, so that the residual liquid inside the liquid injection cup 9 is cleaned.

[0034] After the cleaning is completed, the driving cylinder drives the cleaning sleeve 51 and the blocking rod 52 to reset, thus completing a cleaning process.

[0035] In this embodiment, a sleeve end joint 513 is provided at the upper end of the cleaning sleeve 51, and the sleeve end joint 513 is connected to an air inlet joint 54 at the mouth of the air inlet hole 511, and the air inlet joint 54 is used to connect to an external air source.

The blowing holes 512 arranged at a 45° angle enable the blowing to have a downward sweeping force on the residual liquid inside the liquid injection cup 9, which is convenient for cleaning the residual liquid. Of course, in other embodiments, the implementer can also set a suitable inclination angle according to the specific implementation situation when it meets the needs. There are multiple blowing holes 512, and the multiple blowing holes 512 are evenly arranged circumferentially at the lower end of the cleaning sleeve 51.
