The strip grooves 19 are provided in the strip grooves A flip push rod 20 is provided on both sides through the movement of a rotating pin, and one side of the two flip push rods 20 is in contact with one side of the lower end of the push block 21 respectively. An oil storage groove 17 is horizontally opened on one side of the grabbing movable seat 7 that is sleeved with the sliding sleeve 8. The upper and lower sides of the oil storage groove 17 are respectively sleeved with the sliding sleeve 8 and are provided with sealing rings. One side of the two oil storage grooves 17 is respectively connected to the upper end of the press-in groove 10 and an oil feeding groove 18 is opened on one side. When the circular plate 15 controls the first piston 13 and the second piston 14 to rise, the height of the second piston 14 from the connecting groove 12 is less than the height of the upper end of the first piston 13 from the upper part of the press-in groove 10. When the second piston 14 blocks the connecting groove 12, a certain amount of lubricating oil is still stored above the first piston 13;

[0038] A one-way valve 39 may be provided in the oil delivery groove 18. When the lubricating oil above the first piston 13 continues to rise, the lubricating oil will be pushed into the oil delivery groove 18, and then enter the oil storage groove 17 by pushing the one-way valve 39. A seepage groove 40 is provided horizontally through the inner and outer sides of the sliding sleeve 8 close to the oil storage groove 17. When the lubricating oil enters the oil storage groove 17, the lubricating oil flows into the contact position between the sliding sleeve 8 and the guide rod 6 through several seepage grooves 40, maintaining and lubricating several balls 9, thereby improving the service life.

When the grabbing movable seat 7 is lifted to the maximum extent, the lower ends of the two toggle blocks 36 respectively abut against the upper ends of the two flip push rods 20 extending from the grabbing movable seat 7. When the grabbing movable seat 7 does not rise to the highest point during normal use, when the ball 9 needs to be automatically maintained and lubricated, the telescopic rod 22 is controlled to push the grabbing movable seat 7 to the highest stroke. At this time, the two flip push rods 20 abut against the lower ends of the toggle block 36, and the flip push rod 20 flips along the rotation pin shaft, and the end of the flip push rod 20 away from the toggle block 36 is lifted, pushing the push block 21 and the circular plate 15 to rise, so that the lubricating oil is pushed into the oil delivery groove 18.

[0040] In this embodiment, the control telescopic rod 22 is pneumatically controlled to move the grabbing movable seat 7 up and down, and the independent placement box 5 controls the grabbing movable seat 7 to rotate horizontally. When a clamping claw of the grabbing movable seat 7 moves to the battery cell position, the battery cell is grabbed, and then the independent placement box 5 rotates to control the clamping claw on one side of the grabbing movable seat 7 to be above the independent placement box 5 of the first rotating disk 3, the grabbing movable seat 7 is lowered, and the clamping claw is released, and the battery cell is filled into the battery cell shell. After the sliding sleeve 8 has been used for a long time, the grabbing movable seat 7 is selectively lifted to the highest position, and the toggle block 36 pushes the flip push rod 20 to flip, so that the flip push rod 20 controls the push block 21 and the circular plate 15 to lift. When the circular plate 15 controls the first When the piston 13 and the second piston 14 rise, the height of the second piston 14 from the connecting groove 12 is less than the height of the upper end of the first piston 13 from the upper part of the pressed groove 10. When the second piston 14 blocks the connecting groove 12, a certain amount of lubricating oil is still stored above the first piston 13. When the lubricating oil above the first piston 13 continues to rise, the lubricating oil will be pushed into the oil feeding groove 18, and then enter the oil storage groove 17 through the pushing one-way valve 39. The side of the sliding sleeve 8 close to the oil storage groove 17 is horizontally penetrated by the inner and outer sides with an infiltration groove 40. When the lubricating oil enters the oil storage groove 17, the lubricating oil flows into the contact position of the sliding sleeve 8 and the guide rod 6 through several infiltration grooves 40.

[0041] Embodiment 2: On the basis of embodiment 1, an auxiliary cleaning component is provided to blow air to clean the cylindrical shell 34 in the independent placement box 5. The auxiliary cleaning component includes a switching slot 23 and a plurality of cleaning slots 33. The switching slot 23 is provided in the second rotating disk 4, and the plurality of cleaning slots 33 are provided in the independent placement box 5. The first drive seat 1 is located below the independent placement box 5 and is horizontally provided with a tray. A first diversion slot 28 is horizontally provided on one side of the tray close to the second drive seat 2. An annular piston 24 is horizontally inserted in the switching slot 23. A support spring 25 is provided at the lower end of the annular piston 24. A plurality of downward push rods 26 are vertically symmetrically provided on the upper end of the annular piston 24. The upper parts of the plurality of downward push rods 26 are movable and pass through the second rotating disk 4 and are horizontally provided with The annular push plate 27 and the upper ends of both sides in the switching slot 23 respectively penetrate the second rotating disk 4 and are provided with a first pipe groove and an air joint 37. An air supply pipe 38 is sealed and plugged in the first pipe groove. The side of the air supply pipe 38 away from the second rotating disk 4 is connected to the side of the first diversion slot 28. When the grabbing movable seat 7 is put into the shell and lowered, the annular piston 24 squeezes the support spring 25 and descends. At this time, the air joint 37 is connected to the air supply pipe 38. After each drop of the grabbing movable seat 7, the grabbing movable seat 7 will push the annular push plate 27 and the downward push rod 26 to control the annular piston 24 to squeeze the support spring 25 in the switching slot 23. The high-pressure gas connected to the air joint 37 will enter the air supply pipe 38 through the switching slot 23 and then be sent to the first diversion slot 28.

[0042] The tray of the first driving seat 1 is located above the first diverter groove 28 and is embedded with an elastic rubber plate 29. The elastic rubber plate 29 penetrates and communicates with the first diverter groove 28 to open a plurality of first docking holes 30. A second diverter groove 31 is horizontally clamped at the lower end of the independently placed box 5. A plurality of second docking holes 32 are penetrated and opened at the lower end of the second diverter groove 31. The plurality of second docking holes 32 are correspondingly arranged with the plurality of first docking holes 30. The lower ends of the plurality of cleaning grooves 33 are respectively connected to the second diverter groove 31, and the upper ends of the plurality of cleaning grooves 33 are respectively inclined downward to communicate with the inner cavity of the independently placed box 5, and A cylindrical shell 34 is placed in the inner cavity of the independent placement box 5. After the high-pressure gas enters the first diversion groove 28, it enters the second diversion groove 31 through the first docking hole 30 and the second docking hole 32, and then blows into the inner cavity of the independent placement box 5 and the cylindrical shell 34 from the plurality of cleaning grooves 33, so that the pollutants in the cylindrical shell 34 and the independent placement box 5 are blown out with high pressure. The high-pressure wind force will not push out the battery cell, and under the action of the cylindrical structure of the cylindrical shell 34, the high-pressure wind will be blown upward. The upward airflow can play a buffering effect during the falling process of the battery cell, and can clean the surface of the fallen battery cell.

[0043] As the first rotating disk 3 rotates, only the cylindrical shell 34 that reaches the position of the first diversion groove 28 can be cleaned. An ejection hole 35 is opened at the center of the lower end of the independent placement box 5, which can cooperate with the lifting rod to facilitate the cylindrical shell 34 to be separated from the independent placement box 5.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
