This device, through setting up spacing subassembly 6, it utilizes the telescopic characteristics of axle sleeve 28, utilizes the slope direction of spacing 38, through spacing axle sleeve 28 lifting to carousel 37 to make polishing dish 3 break away from with the frame structure, form the last unloading function of frame, and this in-process relies on polishing dish 3 self route to remove completely and realizes, need not to establish in addition control, reduces the driving source and arranges, increases the synchronism and the convenience of device.
The end side walls of the guide grooves 15 are all fixed with a push-closed button 40 through bolts, the push-closed button 40 is in control connection with the motor 12, when the guide roller 22 moves to the end of the guide groove 15, the push-closed button 40 is touched to generate an electric signal, and accordingly the motor 12 is controlled to reversely reset, and automatic control is achieved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
