Abstract

The present invention comprises: a holding jig for supporting a processing object; a brush rotating/driving portion arranged on the holding jig so as to rotate a brush such that the processing object is polished; an X-axis direction driving portion for moving the brush rotating/driving portion in the X-axis direction; a Y-axis direction driving portion for moving the brush rotating/driving portion in the Y-axis direction; a Z-axis direction driving portion for moving the brush rotating/driving portion in the Z-axis direction and thereby pressurizing the surface of a processing surface of the processing object such that a deformed end side surface of the brush polishes the processing surface; and a processing material applying portion arranged behind and near the brush rotating/driving portion so as to move forward/backward such that a processing material made of the same material as that of the processing object is micro-applied to the surface of the brush. The present invention is advantageous in that, when the processing surface of the carbon jig/carbon mold is polished, a preprocessed pitch portion of the processing surface is polished by an end side surface that is deformed when the processing surface is pressurized while a processing material (for example, carbon) made of the same material as that of the jig remains applied to the surface of the polishing member; this prevents scratching due to a contact with an end portion of the polishing member and decreases the initial jig oxidation phenomenon resulting from partial counterbalance of oxygen component adsorption following formation of a carbon material raw surface, thereby extending the life; the luminance in connection with surface gloss could not be implemented in the case of a manually produced product; the flatness-related quality is excellent; and operations can proceed irrespective of the shape of the processing object.

Description

Carbon Jig / Carbon Mold Polishing Machine for Mobile Device Glass Production

The present invention relates to a carbon jig / carbon mold polishing machine for glass production of mobile devices, and more particularly, to improve the production process of the carbon jig / carbon mold for glass production of mobile devices, including smart phones, etc. In addition, the present invention relates to a polishing machine capable of performing an ultra-fine polishing operation and reducing processing time.

In general, the display window used in the mobile phone was inexpensive and easy to produce acrylic resin, but as the method of carrying out the mobile phone function by touch has recently become more widespread, as synthetic resin materials such as acrylic, scratch problems (strength problems) and heat Tempered glass is being used in touch panels because it can no longer be used due to fragility, low transmittance and battery consumption issues to maintain brightness.

Tempered glass cuts the original glass to have the appearance of the window glass, then grinds the outer shell, and performs other hole processing, chamfering, and polishing the inner surface to process the outer surface. Subsequently, the surface of the window glass is polished on both sides, and after the washing step and the reinforcing process, the manufacturing of the window glass is completed.

In the manufacturing process of tempered glass, surface polishing on both sides of the window glass may be finished in a relatively simple process in the case of plate-shaped glass, but surface polishing may be effectively performed when the surface of the window glass is curved. none.

As such, the curved window glass outer diameter grinder of the mobile device of the prior art 1 for surface polishing may use an abrasive to polish the outer diameter of the curved window glass, and may include a jig part for fixing the glass to be polished and a tilting motion of the jig part. A glass jig unit comprising a jig movement unit for tilting movement; A glass comprising an abrasive jig including a polishing jig, an abrasive jig lifting part for lifting the jig up and down in the Z-axis direction, and a polishing jig left and right moving part for reciprocating the polishing jig from the front in the X-axis direction. A polishing unit; An abrasive circulating unit for supplying an abrasive required for polishing in the glass polishing unit and circulating the abrasive to be recovered and reused after use; A control unit for driving and controlling the glass jig unit, the glass polishing unit, and the abrasive circulation unit; A frame part including a work table having the glass jig part, the glass polishing part, and the abrasive circulation part installed and fixed thereto, and having a working space horizontally to allow the jig table to be moved and polished; It consists of a vacuum pump unit including a vacuum pump for sucking the air into the vacuum suction tube to suck the air to the jig to suck and fix the glass using a vacuum.

However, the curved window glass outer diameter grinder of the mobile device of the prior art 1 grinds through the polishing jig during the tilting reciprocating motion of the glass. Since it has to be removed, there was a problem that the number of processes and the process time increases.

The substrate polishing apparatus of the prior art 2 includes a table on which a substrate is seated; A polishing wheel formed in a cylindrical shape and polishing an edge of the substrate with a circumferential surface; And a spindle for driving the polishing wheel. The edge of the substrate having a curved surface may be polished, and the corners and sides of the substrate may be polished as well as the edge of the substrate in one device of the substrate.

However, the substrate polishing apparatus of the prior art 2 also has a problem in that the contact portion is caused by repeated friction of the polishing wheel like the cited invention 1, which causes the quality deterioration.
