[0026] In an embodiment of the present invention, please refer to Figure 10 and Figure 11 The rotating assembly 13 shown in the figure includes a sleeve 47 fitted onto the outer side of the threaded rod 35. A limiting block 48 that is slidably connected to the threaded rod 35 is fixedly connected inside the sleeve 47. A sliding groove 49 that is adapted to the limiting block 48 is provided on the threaded rod 35. A drive wheel 50 is fixedly connected to the outer side of the sleeve 47. A belt 51 is drivenly connected to the outer side of the drive wheel 50. A driven wheel 52 that is fixedly connected to the liquid storage tank 14 is drivenly connected to the belt 51.

[0027] In an embodiment of the present invention, before polishing, the polishing liquid inside the storage tank 14 is first transported to the outlet pipe 22 by the pump body 15, and then the polishing liquid is transported to the diversion pipe 21 through the outlet pipe 22. After passing through the diversion pipe 21, it is transported to the two sets of connecting pipes 20, and then the polishing liquid is transported to the fixed frame 5 through the through hole 7 and flows onto the application sponge 6. Then, the second motor 44 is started, and the start of the second motor 44 causes the second drive shaft 45 to rotate. The rotation of the second drive shaft 45 drives the... The coupling 46 rotates, which in turn drives the threaded rod 35 to rotate. The rotation of the threaded rod 35 drives the threaded block 34 to move. The movement of the threaded block 34 causes the sliding plate 31 to move the liquid storage tank 14. After the liquid storage tank 14 moves, it will drive the fixed frame 5 to move through the connecting part 16. The movement of the fixed frame 5 causes the application sponge 6 to move, which in turn causes the application sponge 6 to gradually move onto the grinding wheel 2. At this time, the threaded block 34 is just separated from the threaded rod 35 and located on the connecting shaft 38, and it compresses the spring 41. Furthermore, after the sponge 6 is attached to the grinding wheel 2, the second motor 44 continues to rotate. Later, it disengages from the threaded rod 35 from the threaded block 34. At this time, the rotation of the threaded rod 35 will no longer drive the threaded block 34 to move. However, due to the action of the sliding groove 49 and the limiting block 48, the sleeve 47 will rotate. The rotation of the sleeve 47 will cause the drive wheel 50 to rotate. The rotation of the drive wheel 50 will drive the belt 51 to rotate. Then, the belt 51 will drive the driven wheel 52 to rotate. The rotation of the driven wheel 52 will drive the liquid storage tank 14 fixedly connected to it to rotate. The rotation of the liquid storage tank 14 will cause the connecting part 16 to drive the connecting pipe 17 to rotate. The rotation of the connecting pipe 17 will cause the fixed frame 5 to rotate, which in turn will drive the sponge 6 to rotate. Thus, the sponge 6 will evenly apply the polishing liquid to the grinding wheel 2. Furthermore, the second motor 44 is then reversed. After the second motor 44 reverses, the threaded block 34 is pressed against the threaded rod 35 due to the elastic force of the spring 41. Then, after the threaded rod 35 reverses, it will drive the threaded block 34 to move in the opposite direction, thereby causing the sliding plate 31 to drive the liquid storage tank 14 to move in the opposite direction. Then, through the connecting piece 16, the fixed frame 5 drives the cleaning sponge 8 to move in the opposite direction to free up the grinding wheel 2. After that, the fixed plate with the jumper wire is installed on the machine body 1, and the end face is ground by the grinding wheel 2. Furthermore, after the polishing is completed, the fixing plate is removed. At the same time, the first motor 25 is started by controlling it. After the first motor 25 is started, it will drive the first drive shaft 26 to rotate. The rotation of the first drive shaft 26 will drive the first bevel gear 28 to rotate, which in turn will drive the second bevel gear 29 to rotate. The rotation of the second bevel gear 29 will drive the transmission to rotate. The rotation of the transmission shaft 30 will drive the connecting pipe 17 to rotate, which in turn will drive the fixing frame 5 to rotate. The rotation of the fixing frame 5 will cause the application sponge 6 and the cleaning sponge 8 to flip and switch. Furthermore, after the flipping, the second motor 44 is started, causing the threaded rod 35 to rotate. At this time, the rotation of the threaded rod 35 will once again drive the fixed frame 5 to move down until the cleaning sponge 8 is in contact with the polishing wheel 2. Then, the second motor 44 continues to rotate, causing the driving wheel 50 to drive the driven wheel 52 to rotate through the belt 51, thereby causing the cleaning sponge 8 to rotate and clean the polishing wheel 2. After cleaning is completed, the second motor 44 reverses to reset the cleaning sponge 8. After resetting, the first motor 25 is started, causing the fixed frame 5 to rotate. After the fixed frame 5 rotates, the cleaning sponge 8 and the application sponge 6 flip and switch positions again to prepare for the next polishing.
