The present invention relates to a wheel scriber, and more particularly to a wheel scriber equipped with a glass cutting disc for forming a scribe line on the surface of a glass substrate.

Generally, glass used in the manufacture of flat panel displays such as thin film transistor-liquid crystal display (TFT-LCD), organic light emitting display (OLED), plasma display panel (PDP), and electro luminescent (EL) The substrate is manufactured through a molding process for forming molten glass dissolved in a glass melting furnace into a flat plate and a cutting process for cutting to meet primary standards, and then transported to a processing line for processing.

Thereafter, desired physical processing is performed on the glass substrate, and the secondary cutting step is performed in a form suitable for the shape of a commercial product.

In the glass cutting process, many defects are generated due to various factors. That is, in the cutting process, a size error, linearity error, chips, cracks, and the like are generated, and in the handling process, a change in position of the azimuth mark and a crack are generated.

The cutting of such glass is realized by a scribe wheel provided with a glass cutting disc formed on the scribe line on the surface of the glass.

In general, as shown in FIG. 1, the glass cutting disc 11 has an outer diameter of 1 to 20 mm, a thickness of 0.6 to 5 μm, and to form a central hole 12 and a peripheral rigid. The predetermined blade angle includes a peripheral edge 13 beveled radially outward at 90-160 °.

Korean Unexamined Patent Publication No. 1997-25885 (June 24, 1997) discloses a disc as shown in FIG.

2 is a front view of a conventional glass cutting disc.

In Fig. 2, the glass cutting disc 11 has a circular configuration in which the predetermined thickness is T and the predetermined maximum diameter is ø. The cutting disk 11 is formed with a center hole 12 for receiving a support spin (not shown). The opposite outer circumference of the cutting disc 11 is beveled radially outward and received at a predetermined 2θ to form a sharp peripheral ridge.

As shown in FIG. 2, the peripheral edge 13 of the cutting disc 11 consists of regular surface properties of alternate projections and U-shaped grooves alternately over the circumference of the cutting disc 11. The projections have a height in the radial direction of the cutting disk 11 from the base of each U-shaped groove to a point on the peripheral edge 13, each neighboring projection having a predetermined pitch of the cutting disk 11. Space is circumferential.

3 shows a grinding machine used to form the surface properties of the peripheral edge 13 of the cutting disc 11 shown in FIG. 2. Such a grinding machine comprises a drive motor M having a drive shaft installed for rotation of a disc-shaped grindstone or abrasive cutting wheel Z together. The disk 11a forming the cutting disk 11 is installed on the spindle S to rotate together, and is located below the disk-like grindstone Z to lie perpendicular to the drive shaft of the drive motor M. . The spindle S is connected with a stamper motor to drive the spindle intermittently.

Therefore, the grinding machine corresponds to the pitch after the spindle S moving the disk 11 moves from the grinding position to the return position whenever one surface characteristic is formed at the peripheral edge 13 of the disk 11a. Rotate intermittently at each distance, and then match the portion of the peripheral edge 13 on which continuous surface characteristics are to be formed with the peripheral edge of the grindstone Z, and then the spindle S moves from the return position to the grinding position to form a groove. do.

4 shows a scribe header 62 in which the glass cutting disc 11 shown in FIG. 1 or 2 is mounted. Since the configuration of such a header can be easily achieved by a conventional technique in the art, the detailed description thereof is omitted.

However, in the above-described scribing apparatus to which the prior art is applied, there is a problem in that when the scribe line is formed on the glass, the force applied from the header to the wheel disk is small, and the scribe line breaks out when the glass breaks.

In addition, the technique disclosed in the above publication adds a process of forming protrusions on the peripheral edge of the glass cutting disc, which not only increases the manufacturing cost, but also the state of fitting the center hole and the spindle passing therethrough when processing the protrusion shape. There was also a problem that machining was difficult because of relaxation.
