Description

Glass panel engraving device and engraving method

The invention relates to a glass panel marking device and a marking method, in particular to a glass panel marking device and a marking method. When a traveling direction of a reel is changed, a crack is formed obliquely to make the next step. A cutting process is easier to carry out.

In general, a flat display panel, such as a liquid crystal display (LCD) panel, an organic electroluminescent (OEL) panel, an inorganic electroluminescent panel, a transmissive projection substrate, a reflective projection substrate, or the like, It is obtained by cutting a mother glass panel made of a fragile material such as glass into a plurality of panels of a predetermined size.

The cutting process of the glass panel includes a scribe line program and a cutting program. The scribe line program uses a tool made of diamond to form a plurality of cutting lines on the surface of the glass panel, or a tool with a higher hardness than the glass panel can be used for the scribe line process. The cutting process cuts the glass panel along the formed cutting line.

As shown in FIG. 1A, a conventional line device for performing a scribe line program includes a reticle, a wheel support unit, and a reticle.

As shown in FIG. 1A, the conventional reticle device A includes a reticle head 1, a wheel support unit 4, and an annular reticle 5. The wheel support unit 4 is mounted on the engraving head 1 and horizontally rotatable. The engraving reel 5 is disposed at the lower end of the wheel support unit 4 and can be rotated vertically, so that when the engraving wheel 5 is pressed against the glass panel A crack is formed.

Further, the wheel support unit is rotatable in the horizontal direction by the bearing 9.

According to the above-described scribe line device, the scribe head 1 is moved along one of the cutting lines on the glass panel, and at the same time, a crack is formed on the surface by the scribe wheel 5 contacting and pressing one surface of the glass panel.

In addition, FIGS. 1B to 1D show the technical features of the wheel support unit 4 and the reeling wheel 5.

As shown in FIGS. 1B to 1D, a plug 7 is provided at the center of rotation of the reeling wheel 5. The plug 7 is horizontally inserted into the bolt hole 8 of the wheel support unit 4.

Therefore, when the reticle 5 is scribed on the glass panel, the reticle 5 is rotated to form a vertical slit on the glass plate and along the cutting line.

The center of rotation of the wheel support unit 4 is offset from the vertical imaginary line passing through one of the reticle 5, which enables the wheel support unit 4 to more accurately align with the reticle 5.

However, when the traveling direction of the reel 5 is changed by 90 degrees, an effective crack cannot be formed at the corner, and thus a bad cutting surface is generated in the subsequent cutting process.

In view of the above problems, it is an object of the present invention to provide a reticle device for a glass panel and a scribe line method thereof, which can perform one cut by obliquely forming a crack when a traveling direction of the reticle is changed. The program is easier to work with.

To achieve the above object, a reticle apparatus for a glass panel according to the present invention comprises a reticle, a wheel support unit and a reticle. A wheel support unit is mounted on the engraving wheel. The sprocket wheel is rotatably disposed at a lower end of the wheel support unit, a plurality of bolt holes are formed in the wheel support unit, a plug is inserted into the rotation shaft of the reticle, and both ends of the plug The department is inserted into the bolt holes of the wheel support unit. Wherein the surface of the outer peripheral edge of the end of the plug is curved such that the cross-sectional diameter of the end portions of the plug is smaller toward the tip end of the end portions, and the outer peripheral surface of the plug is opposite to the end There is a plurality of gaps between the pin holes of the wheel support unit, and the score wheel can be tilted according to an imaginary line perpendicular to a surface of one of the glass panels when performing a scribe process.

In one embodiment, the peripheral surface of the ends of the plug is parabolic, partially circular, or partially elliptical.

To achieve the above object, a reticle method of the present invention is performed on a glass panel by a reticle device comprising a reticle, a support unit and a reticle, the wheel support unit being mounted at the moment a reel, the reel is rotatably disposed at a lower end of the wheel support unit, a plurality of bolt holes are formed in the wheel support unit, a plug is inserted into the rotation axis of the reel, and the plug is inserted Both ends of the bolt are inserted into the bolt holes of the wheel support unit. Wherein, when the engraving wheel travels and changes direction in performing a scribe line program, the plug is tilted within the bolt holes such that the reticle is tilted according to an imaginary line perpendicular to a surface of one of the glass panels, The crack is inclined according to an imaginary line perpendicular to the surface of the glass panel.

As described above, since the plug is tilted in the bolt hole of the wheel support unit when the traveling direction of the reel is changed, the reel can make the generated crack face the inner side of the corner of the turn and according to the glass panel. Tilting in one of the vertical directions makes it easier to cut the glass panel in the next cutting process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a glass panel engraving apparatus and a reticle method according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein the same elements will be described with the same reference numerals.

A reticle apparatus for a glazing panel according to the present invention still includes the basic composition of the reticle apparatus shown in FIG.

That is, the score line of the present invention includes a reticle, a support unit, and a reticle. Wherein, the wheel support unit is mounted on the reticle and can be rotated in a horizontal direction, and the reticle is disposed at the lower end of the wheel support unit and is rotatable.

The bolt hole is formed at the lower end of the wheel support unit, and a plug is inserted at the center of rotation of the score wheel. The two ends of the plug are inserted into the bolt holes of the wheel support unit.

The configuration of the wheel support unit and the reel of one embodiment of the present invention will be further described below.

2A is a schematic diagram of a combination of a wheel support unit and a reel of the present embodiment, FIG. 2B is a combination diagram of the reel and a plug shown in FIG. 2A, and FIG. 2C is a wheel support unit shown in FIG. 2A and A front cross-sectional view of one of the reeling wheels, and FIG. 2D is a cross-sectional view of the plug shown in FIG. 2C at an oblique angle.

As shown in FIGS. 2A to 2D, in the reticle apparatus of the glass panel of the present invention, the surface of the outer peripheral edge of the both end portions 71 of the plug 70 is curved so that the diameter of the cross section of the plug 70 is closer to the plug 70. The tip of both ends is smaller.

There is a plurality of gaps 42 between the outer peripheral surface of the plug 70 and the pin holes 41 of the wheel support unit 40, which allows the plug 70 to tilt within the pin holes 41. Therefore, when the reticle 50 is performing a scribe process, it can be tilted according to an imaginary line perpendicular to one surface of the glass panel P (as shown by the arrow in Fig. 2D). In this case, the gap 42 needs to be adjusted in advance so as not to vibrate the plug 70 in one direction perpendicular to its long axis direction during the scribe line process.

Further, when the plug 70 is inclined in the bolt hole 41 of the wheel support unit 40, both end portions of the plug 70 are in contact with the inner surface of the bolt hole 41. In addition, since the both end portions of the plug 70 are curved, and the diameter of the cross section of the plug 70 is smaller toward the tip end portions of the plug 70, the inner surface of the bolt hole 41 can be prevented from being recessed, and Thus, the plug 70 can be smoothly rotated and the service life of the wheel support unit 40 is promoted.

Although the ends of the plug 70 shown in the drawings are parabolic, the ends may be other curves, and are not limited thereto. In the present embodiment, since the peripheral surface of the both end portions of the plug 70 is in line contact with the inner surface of the bolt hole 41 or a small area of contact, the plug 70 can be smoothly rotated in the bolt hole 41.

In addition, FIGS. 3A and 3B show that the end portion of the plug 70 is partially circular or partially elliptical, in which case the plug 70 can be in line contact with the wheel support unit 40 even under a slight angle of inclination. .

4 is a schematic view showing a scribe line process of the reticle device of the present embodiment, wherein the scribe line device has a change direction of travel, and FIG. 5 is a schematic view of a crack generated by the scribe line device at a plurality of points shown in FIG.

As shown in FIG. 4, when the reticle device performs a scribe line program and changes the traveling direction, the plug 70 is inclined within the pin hole 41 and is inclined according to an imaginary line perpendicular to one surface of the glass panel P.

Thereby, as shown in FIG. 5, the direction of the crack formed in the glass panel P becomes inclined.

When the reticle 50 is traveling and changing direction, the reticle 50 becomes continuously laterally inclined such that the formed crack is inclined in accordance with an imaginary line perpendicular to the surface of the glass panel P.

This is because when the lower end portion of the sprocket 50 is not slid in accordance with the long axis direction of the plug 70, the wheel support unit 40 or the reticle provided at the upper end of the reticle 50 is instantaneously centrifugally The outer side of the corner that tends to turn.

As a result, when the reticle 50 is changing direction and passing the corner of the turn, the crack becomes continuously inclined along the lateral direction of the reticle, thereby lifting the subsequent cutting process and reducing the cutting quality of the surface.

Reference numeral 60 shown in Fig. 4 represents a cutting line formed by the reticle device.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
