Hereinafter, referring to FIG. 9, a method for automatically processing a thin glass plate for protecting a smartphone camera according to a procedure for processing a thin glass plate will be described in detail. Like reference numerals denote like elements throughout.

A method for automatically processing a thin glass plate for protecting a smartphone camera according to the present invention includes a loading step (S10) of loading a glass sheet to be chamfered through a loading unit (110) onto a transfer unit (130) A first feeding step (S20) of feeding the thin glass sheet fed in step S10 to the first feeding part (131) and feeding the fed thin glass sheet in the direction of the first processing part (121) A first machining step 30 for machining the upper surface corner portion of the thin glass sheet supplied in step S20 from the first machining part 121 to form a first chamfer, (S40) for feeding the thin glass sheet fed in the direction switching step (S40) to the second feeding part (133) and rotating the supplied thin glass sheet A second transfer step (S60) of supplying the transfer material in the direction of the second processing part (122) When the glass sheet from the supply (S60) and a second processing step (S70) the second chamfered to machine the edge portion from the second processing section 122.

Before starting the loading step (S10), the operator first carries out the operation preparing step of the glass foil automatic chamfering machine 100 for protecting the smartphone camera.

In the operation preparation step, the tank water level of the polishing water is generally checked, and the state of the polishing water pump and the state of the filter are checked. Open the valve of the polishing water pump, check the pressure of the air pressure gauge, and check the pressure of the vacuum pump. Further, idling of the processing apparatus is performed, and the glass sheet to be processed is aligned on the tray (T).

When the operation preparing step is completed, the loading step S10 is performed. The loading step (SlO) feeds the glass foil to the transfer unit (130) through the loading unit (110).

At this time, a first polishing water supply step (S11) for supplying polishing water from the first polishing water supply part (150) to the thin glass plate is performed between the loading step (S10) and the first transfer step (S20). Of course, the first polishing water supply step S11 may be performed before the loading step S10.

The cutting distance between the first transferring unit 131 or the second transferring unit 133 and the machining unit 120 is adjusted corresponding to the set grinding size of the thin glass plate before the first transferring step S20 is performed The fine distance adjustment step S12 is performed.

The fine distance adjustment step S12 is performed through the fine distance adjustment part 135 and the grinding size of each of the first transfer part 131 and the second transfer part 133 can be adjusted.

The first transfer step S20 includes a first pushing step S21 for pushing the glass sheet supplied in the loading step S10 toward the belt rotating on the first transferring unit 131. [

The first pushing step S21 functions to push the thin glass plate through the first pushing part 132 and the thin glass plate is transported in the belt direction of the first transporting part 131 together with the polishing water.

In the first transfer step S20, the belt is rotated to transfer the thin glass plate to the first processing unit 121 while rotating.

In this case, when the glass sheet is circular, the upper surface corner of the glass sheet is chamfered while the belt rotates at a constant speed.

When the glass sheet is polygonal in the first transfer step S20, the belt is rotated stepwise so as to control the rotation angle of the glass sheet corresponding to the central angle formed by each side at the center of rotation corresponding to the number of sides of the polygon (S22).

The first processing amount control step (S22) is performed such that, for example, when a thin glass sheet of a streamlined rectangular shape is processed, the belt of the first transfer section 131 is rotated so that the first side of the thin glass sheet is rotated, When the processing of the fourth side surface is completed in order, the upper surface processing of the streamlined rectangular glass thin plate is completed.

The first machining step (S30) grinds through the first machining part (121), and performs chamfering of the thin glass plate to be conveyed through the belt.

After the chamfering of the upper edge of the glass sheet is completed, the direction changing step S40 is performed to reverse the glass sheet by the second conveying unit 133 through the reversing unit 140. [ Thus, chamfering of the corner portions of the upper and lower surfaces of the glass sheet can be automatically performed.

When the direction change step S40 is completed, a second polishing water supply step S50 for supplying polishing water from the second polishing water supply part 160 onto the thin glass plate and the second transfer part 133 is performed. Of course, the second polishing water supply step (S50) may be controlled so as to be performed simultaneously with the first polishing water supply step (S11).

The second conveying step S60 is a step of performing a second pushing step S61 of pushing the glass sheet fed in the direction changing step S40 toward the belt rotating on the second conveying part 133, A second processing amount control step (step S60) of rotating the belt in a stepwise manner so as to control the rotation angle of the glass sheet corresponding to the central angle corresponding to the number of sides of the polygon when the thin glass sheet is polygonal in the second transfer step S60 S62). The second transfer step S60 and the second machining step S70 are the same in the order and process of the first transfer step S20 and the first machining step S30, So that redundant explanation will be omitted.

Finally, an unloading step (S80) for discharging the thin glass sheet after completion of the second processing step (S70) to a separate discharge tray or to the outside is performed.

The unloading step S80 may be performed such that the glass sheet is aligned on the discharge tray in the same manner as the loading step S10, and is discharged from the second transfer part 133 to the outside without a separate unloading unit It is possible.
