Description

TECHNICAL FIELD [0001] The present invention relates to a cutting apparatus for cutting a glass sheet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cutting a glass plate, and more particularly, to a technique for cutting a glass plate to separate a closed region from the glass plate.

Embrittlement refers to the property that when a force above the elastic limit is applied to an object, it is destroyed without permanent deformation, or only a part of it is permanently deformed. As the plate member made of a material having brittleness, a glass plate is typical.

Generally, cutting of a brittle material plate member such as a glass plate is performed by forming a scribe line by a scribe groove along a line to be cut on a surface through a scribing operation, and then applying a force to the scribe line. In some cases, the cut portion is cooled down to use thermal stress. However, in the conventional cutting method, the cut surface is generally perpendicular to the glass plate. Therefore, when the closed area is separated, a situation in which it does not fall off from the cut inner area and the outer area frequently occurs, and improvement is required. This situation becomes more frequent and stronger as the glass plate is thicker.

An object of the present invention is to provide a cutting apparatus and a cutting method which can easily separate a closed region from a glass plate.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, including: a base portion on which a glass plate is mounted and fixed; A scribing line forming unit having a cutter blade arranged to be inclined with respect to the glass plate and a cutter transferring unit configured to transfer the cutter blade to the glass plate; And a cooling unit for rapidly cooling the glass plate.

The scribing line forming portion may include a translating portion for translating the cutter blade in three dimensions and a cutter rotating motor for adjusting a traveling direction of the cutter blade.

The scribing line forming unit may further include a cutter coupling unit coupling the cutter blade to the cutter transferring unit. The cutter coupling unit includes a first coupling unit coupled to the cutter transfer unit, and a second coupling unit coupled to the cutter blade, A second engaging portion rotatably coupled to the first engaging portion, and an angle adjusting portion adjusting the rotation angle of the first engaging portion and the second engaging portion.

The first coupling portion may be movably coupled to the cutter transfer portion in a direction perpendicular to the advancing direction of the cutter blade.

The glass plate cutting apparatus may include a cutter wheel having the cutter blade and a cutter body that supports the cutter wheel and is coupled to the cutter second coupling portion.

The cooling section may have a block-shaped cooling means for cooling the cut region of the glass plate.

According to another aspect of the present invention, there is provided a scribe line forming step of moving a cutter blade on a glass plate to form a closed curve type scribe line by a scribe groove; A cooling step of quenching the area inside the closed curve in the glass plate; And a separation step of separating a region inside the closed curve from the glass plate. In the scribe line forming step, the scribe groove is inclined so that the entire scribe groove is directed toward the inside of the scribe line toward the bottom, The method of cutting a glass plate is provided.

In the scribe line forming step, the degree of tilting of the cutter blade with respect to the glass plate may be adjusted.

According to the present invention, all of the objects of the present invention described above can be achieved. Specifically, since the scribe groove is inclined toward the inside of the scribe line toward the bottom or inclined toward the outside of the scribe groove, the cut surface formed by the quenching is also formed to be easily separated.

Referring to FIG. 1, a glass sheet cutting apparatus 100 includes a base 110, a scribe line forming unit 120, and a cooling unit 160. The glass sheet cutting apparatus 100 forms an inclined scribe groove on the closed curve C in the glass sheet G and rapidly quenches the closed area G2 in the closed curve C to thereby cause the glass sheet G to be separated from the closed region G2 Thereby facilitating separation. For ease of explanation, a typical XYZ Cartesian coordinate system is introduced. The X and Y axes are placed on a horizontal plane, and the Z axis extends along the vertical direction.

The base portion 110 provides a work surface 111 on which a work glass plate G is placed and fixed. Although not shown in detail, the base portion 110 guides the linear reciprocating movement of the scribing line forming portion 120 and the cooling portion 160 in the X-axis direction. A closed area to be separated is indicated by a closed curve C in the work target glass plate G in Fig.

The scribing line forming unit 120 includes a cutter transfer unit 120a and a cutter module 140. [ The scribing line forming unit 120 forms a scribing line extending along the closed curve C on the work glass plate G fixed on the working surface 111 of the base 110. The scribe lines are formed by grooves inclined with respect to the glass plate (G).

The cutter transfer unit 120a includes a first transfer unit 121, a second transfer unit 125, a third transfer unit 130, and a cutter rotation motor 141. The cutter transfer unit 120a rotates the cutter module 140 while translating the cutter module 140 relative to the glass plate G to be worked. The three transfer parts 121, 125, and 130 form a translation part for translating the cutter module 140.

The first transfer unit 121 includes two support columns 122 and 123 and a connection beam 114. The first transfer part 121 is coupled to the base part 110 and reciprocates linearly with precision along the X axis. Although not shown, a driving device for moving the first transfer part 121 relative to the base part 110 is suitably provided. The two support columns 122 and 123 extend along the Z axis and the lower portion is movably coupled to the base 110 and is spaced apart from one another along the Y axis across the working surface 111.

Although not shown, a driving device for moving the third transfer part 130 relative to the second transfer part 125 is suitably provided. The cutter module 140 is fixedly installed in the third transfer unit 130.

The cutter rotation motor 141 is coupled to the third conveyance unit 130 and rotates the rotation shaft 141a at a precise angle about the rotation axis line A extending along the vertical direction. For this purpose, a conventional servo motor is used as the cutter rotation motor 141.

The cutter module 140 has a cutter 150 and a cutter engaging portion 146. [ The cutter module 140 rotates the inclined cutter blade to move along the scribe line path.

The cutter 150 has a body 151 and a cutter wheel 155. The body 151 extends downward from the cutter engaging portion 146 to support the cutter wheel 155. The cutter wheel 155 is rotatably coupled to the body 151 and is provided with a cutter blade 157 having a sharp outer periphery. As the cutter wheel 155, a cutter wheel of a conventional configuration used for cutting glass can be used. The cutter blade 157 passes the glass plate G to form the scribe grooves (g in FIG. 3 and FIG. 4). It will be understood by those skilled in the art that the cutter blade is configured by the cutter wheel in the present embodiment, but may alternatively be constituted by a fixed cutter blade.

The cutter engaging portion 146 includes a first engaging portion 147, a second engaging portion 148, and an angle adjusting portion 149. The cutter engaging portion 146 adjusts the position of the cutter blade 157 with respect to the rotational axis A and the inclination angle of the cutter blade 157 with respect to the glass plate G. [

The first engaging portion 147 is engaged with the engaging member 145 fixed to the end of the rotating shaft 141a of the cutter rotating motor 141. The first engaging portion 148 is movable relative to the engaging member 145 in a direction perpendicular to the extending direction of the cutter blade 157 on a plane parallel to the glass plate G. [ As a result, it becomes possible to position the cutter blade 157 on the rotational axis A.

A cutter 150 is fixedly coupled to the lower surface of the second coupling portion 148. The second engaging portion 148 can rotate about the rotational axis 148a parallel to the extending direction of the cutter blade 157 on a plane parallel to the glass plate G with respect to the first engaging portion 147. [ The inclination angle of the cutter blade 157 with respect to the glass plate G (that is, the inclination angle of the scribe groove (g in Fig. 4) 4 a)) can be adjusted.

The angle adjusting portion 149 includes a first male screw portion 149a, a second male screw portion 149b, and an adjusting knob 149c. The angle adjusting unit 149 adjusts the rotation angle of the first coupling unit 147 and the second coupling unit 148 with respect to the rotation shaft 148a. The first male threaded portion 149a is rotatably engaged with the first engaging portion 147 and extends toward the second engaging portion 148. The second male threaded portion 149b is rotatably engaged with the second engagement portion 148 and extends toward the first engagement portion 147. [ The adjustment knob 149c is provided with a female screw portion (not shown) in which a first male screw portion 149a and a second male screw portion 149b are inserted from both sides, respectively. The rotation angle of the adjustment knob 149c with respect to the rotation shaft 148a between the first engagement portion 147 and the second engagement portion 148 can be adjusted so that the glass plate of the cutter blade 157 G can be adjusted.

The cooling unit 160 includes a cooling transfer unit 160a and a cooling unit 180. [ The cooling unit 160 moves the cooling means 180 to rapidly cool the closed region G2 of the glass plate G to be worked.

The first transfer part 161 is coupled to the base part 110 and reciprocates precisely along the X axis. Although not shown in the drawings, a drive device for moving the first transfer part 161 to the base part 110 is appropriately provided independently of the drive device for moving the first transfer part 121 of the cutter transfer part 120 . The two support columns 162 and 163 extend along the Z axis, the lower portion is movably coupled to the base 110, and is spaced apart from one another along the Y axis across the work surface 111. The two support pillars 162 and 163 extend high above the working surface 111. The connecting beam 164 is positioned on the working surface 111 and extends along the Y axis to connect the two supporting columns 162 and 163. The connection beam 164 serves as a guide for the second transfer part 165.

The second transfer part 165 is coupled to the connection beam 164 of the first transfer part 161 to precisely linearly reciprocate along the Y axis and has a support 166 extending along the Z axis direction. Although not shown, a driving device for moving the second transfer part 165 to the first transfer part 161 is suitably provided. The support base 166 serves as a guide for the third conveyance unit 170.

The third transfer part 130 is coupled to the support part 126 of the second transfer part 125 so as to reciprocate precisely along the Z axis. Although not shown, a driving device for moving the third transfer part 130 relative to the second transfer part 125 is suitably provided. A cooling means 180 is fixedly mounted on the third conveyance table 130.

The cooling means 180 translationally moves on the work surface 111 by the cooling means transfer portion 160a to rapidly cool the closed area G2 inside the scribe line of the glass plate G. Various forms can be used as the cooling means 180. In this embodiment, it is explained that a cooling block cooled by liquid nitrogen is used. Alternatively, a cold cooling gas may be provided to the closed region G2.

The above-described glass sheet cutting apparatus can be constructed by mounting the cutter module on a CNC machine.

Now, with reference to the drawings, a glass cutting method according to an embodiment of the present invention will be described in detail with the operation of the glass cutting apparatus. Referring to FIG. 8, the glass cutting method includes a scribing line forming step (S10), a cooling step (S20), and a separating step (S30).

The scribing line forming step S10 is performed by forming a scribing line on the glass plate G fixed on the work surface 111 by the scribing line forming unit 120. [ In the scribing line forming step (S10), the scribe groove (g) is formed with a constant inclination angle (a) with respect to the glass plate (G). The scribe groove g tilts so as to be directed toward the inside of the closed region G2 or toward the outside toward the bottom thereof. In the present embodiment, the scribe groove g is inclined at an angle a with respect to the glass plate G so that the entire scribe groove g is directed toward the inside of the closed region G2. This scribe groove (g) is formed by adjusting the angle of the cutter 150 by the cutter engaging portion 146. It is preferable that the depth d of the scribe groove g is 5 to 15% of the thickness H of the glass plate G. [

The cooling step S20 is performed by cooling the closed region G2 in the glass plate G on which the scribing line is formed. As the closed region G2 in the scribe line contracts by the cooling step S20, the two regions G1 and G2 are physically cut along the oblique direction of the scribe groove g by the zero stress, .

In the separation step S30, the closed region G2 of the glass plate G is separated from the outer region G1. In this embodiment, the separation step S30 is performed by lifting the closed area G2 to the outer area G1 by means of a suction plate or the like, thereby facilitating the separation by the inclined cutting face L . Alternatively, by fixing the closed region G2 and lowering the outer region G1, the two regions G1 and G2 may be separated. In the case where the cut surface L is inclined so as to extend toward the outer side of the closed region G2 as it goes downward, the outer region G1 is lifted with respect to the closed region G2 to separate the two regions G1 and G2 . In this case, by fixing the outer region G1 and lowering the closed region G2, the two regions G1 and G2 may be separated.

The scribing line forming unit 120 and the cooling unit 160 are configured to be installed on the base 110. However, the scribing line forming unit 120 and the cooling unit 160 Or may be constructed completely separate.

Although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto. It is to be understood that the above-described embodiments may be modified or changed without departing from the spirit and scope of the present invention, and those skilled in the art will recognize that such modifications and changes are also within the scope of the present invention.
