An attaching device includes: a first attaching roller, a second attaching roller, a first distance measurement instrument, and a second distance measurement instrument. The first distance measurement instrument is to measure a distance between a first position of the first attaching roller and a second position of the second attaching roller. The second distance measurement instrument is to measure a distance between a third position of the first attaching roller and a fourth position of the second attaching roller. A straight line defined by the first position and the third position is parallel to an axial line of the first attaching roller, and a straight line defined by the second position and the fourth position is parallel to an axial line of the second attaching roller.

Attaching device

A grinding head includes: a guide rail; a first grinding assembly and a second grinding assembly which are located at two ends of the guide rail respectively and can move along the guide rail; and a number of filling assemblies, which are disposed between the first grinding assembly and the second grinding assembly, wherein dimensions and/or quantity of the filling assemblies are based on a width between the first grinding assembly and the second grinding assembly, wherein the filling assemblies can cooperate with the first grinding assembly and the second grinding assembly to form an entire grinding bottom face. The width of the bottom face of the grinding head can be adjusted so that the waste of grinding cloth due to grinding a thin display is panel surface by a grinding head with a wide bottom face can be avoided and the operating efficiency can be enhanced.
