[0040] In this embodiment, the upper surface of the polishing wheel is detachably connected to the lower surface of the rotating shaft via Velcro; the lower surface of the polishing wheel is the working surface (or polishing surface) during polishing.

[0041] In this embodiment, the driving mechanism capable of driving the grinding and polishing structure to move along the XYZ axes includes an X-axis translation driving unit 61, a Y-axis translation driving unit 62, and a Z-axis translation driving unit 63. Each of these three units is a servo motor and a lead screw and nut driving structure. This is prior art and will not be elaborated upon; the key is that it can drive the grinding and polishing structure to move along the XYZ axes.

[0042] In this embodiment, the fixture is a contour fixture, which facilitates the placement and positioning of the screen to be ground and polished, such as a mobile phone screen 10.

[0043] The working principle and process of this utility model:

[0044] The phone screen is placed on the fixture. The X-axis translation drive unit, Y-axis translation drive unit and Z-axis translation drive unit drive the grinding and polishing structure into position. The polishing drive motor drives the rotating shaft and the polishing wheel installed at the end of the rotating shaft to rotate, polishing and grinding the phone screen. During polishing, the grinding liquid is also fed into the input pipe and the cavity of the rotating shaft by the stirring pump and flows to the polishing wheel for grinding and polishing, ensuring the grinding and polishing effect.

[0045] For grinding and polishing curved screens, the first and second rotation drive units can be used to drive the fixture to rotate at a certain angle to grind and polish the four curved surfaces of the curved screen, thus meeting more screen grinding and polishing needs.
