Description

[0001] Smartphone glass polishing equipment [0002]

The present invention relates to a smartphone liquid crystal polishing apparatus, and more particularly, to a smartphone liquid crystal polishing apparatus which polishes the surface of a tempered glass easily and uniformly when a tempered glass surface is used in a smartphone liquid crystal, ≪ / RTI >

In general, smart phone liquid crystal is a combination of LCD plate and tempered glass, and scratches are generated on the surface of tempered glass according to use. When the depth of scratches on tempered glass is within 10MM, it is polished using a grinding apparatus.

In order to prevent water from entering into the LCD plate, liquid crystal combined with the LCD plate and the tempered glass was separately separated to polish the surface of the tempered glass, Thus, the LCD panel and the tempered glass must be separated to polish and re-bond the surface of the tempered glass, so that the process is complicated and time-consuming.

In order to solve such problems, the LCD plate and the tempered glass were polished while not adhering to each other. However, when the polishing is completed, the wax is melted to prevent water from entering between the LCD plate and the tempered glass. So that the process is complicated and time-consuming.

In addition, in the conventional polishing apparatuses, the surface of the tempered glass is not uniform after polishing because a person manually presses and polishes the rotating plate and can not press at a constant pressure for a polishing time which takes about 1 to 5 minutes, There is a disadvantage in that this grinding operation can be performed.
