A method of cutting a mother substrate by using a laser beam includes the steps of forming a scribing line by irradiating a laser beam for scribing along a line along which the mother substrate is to be cut, rapidly cooling the heated scribing line, And cutting the mother substrate by a cell unit.

A method of cutting a mother board by using a scribe wheel includes the steps of forming a scribe line at a predetermined depth along a line to be cut after contacting the scribe wheel with a line to be cut of the mother board, And cracks are propagated along the scribe lines, thereby cutting the mother substrate in units of cells.

1, the conventional scribing apparatus 1 includes a stage 2 capable of rotating the glass substrate 3 by vacuum suction means and capable of horizontally rotating, and a stage 2 capable of moving the stage 2 in one direction A ball screw 5 for moving the table 2 along the guide rails 12 and a guider 12 provided above the table 2 along the lateral direction, A movable body 6 mounted on the movable body 6 so as to be slidable in the lateral direction on the movable body 6 and an ascending and descending body 14 moving upward and downward by a lifting actuator. The scribe head 8 is provided on the ascending / descending member 14 so that the scribing load can be controlled by the pressing actuator 7. The scribe head 8 has a wheel holder 10 And a diamond wheel 9 mounted on the lower end of the wheel holder 10 so as to be rotatable.

As shown in FIGS. 2 and 3, a pair of parallel guide rails 21 are vertically arranged between the moving body 6 and the ascending / descending body 14, The rear end portion of the lifting actuator 22 arranged in the vertical direction is fixed to the moving body 6 and the driving shaft 22a at the front end portion is fixed to the connecting block 23 fixed to the elevating body 14 .

More specifically, when the interval between the drive shaft 22a and the guide rail 21 in the state where the actuator 22 and the guide rail 21 are parallel is referred to as a reference interval, the driving start position of the actuator 22 and the guide rail The lift mechanism 14 is stuck between the drive shaft 22a and the guide rail 21 at the drive start position and therefore the actuator 22 is driven A large resistance is generated.

Therefore, a large driving force must be applied to the actuator 22 at the initial driving position for descending the ascending / descending member 14. In the process of descending the ascending / descending member 14, the driving shaft 22a and the guide rail 21 As the interval approaches the reference interval, the resistance to the driving gradually disappears, so that the descending speed of the lifting body 14 becomes faster, which makes precise control difficult. When the diamond wheel 9 of the scribing head 8 fixed to the ascending / descending member 14 collides with the substrate in the course of the descent of the ascending / descending member 14 rapidly, the impact applied to the substrate by the accelerating force The diamond wheel 9 and the substrate are damaged. As a result, it is required to replace expensive diamond wheels, to dispose of the target substrate, and to clean the table to remove particles generated in the process of destruction, resulting in an increase in manufacturing cost and a decrease in productivity.

The guide member 130 includes at least two guide members 130 are arranged side by side. In the present embodiment, the guide member 130 is an LM guide including a rail 131 and a sliding block 132, for example. Here, the rail 131 is fixed to the base 110, and the sliding block is fixed to the scribing head 120.

One end of the actuator 140 is connected to the base 110 side and the other end is connected to the scribing head 120 side to vertically move the scribing head 120. In this embodiment, An air cylinder composed of a body to which air pressure is supplied and an action axis to extend or contract by the air pressure from the body is applied will be described as an example. The body of the actuator 140 is fixed to the base 110 and the drive shaft 141 is connected to the scribing head 120 side.

The connection block 150 is disposed at a connection portion between the scribing head 120 and the driving shaft 141 of the actuator 140. In connecting the actuator 140 and the scribing head 120, The driving force transmitted through the driving shaft 141 of the actuator 140 is transmitted to the scribing head 120 in the vertical direction and is connected to be slidable in the horizontal direction.
A guide slot 154 is formed in the connecting block 150 in the horizontal direction and a concave groove 142a slidably coupled to the guide slot 151 in the horizontal direction is formed on the drive shaft 141 of the actuator 140 .
The connection block 150 is connected to the scribing head 120 from the base 110 at a position intersecting the driving shaft 141 of the actuator 140 while one end is fixed to the scribing head 120. [ A guide elongated hole 151 extending in a direction perpendicular to the surface on which the guide member 130 is mounted is formed on the horizontal plane.

The driving shaft 141 of the actuator 140 is provided with a fixing member 142 that slides on the guide slot 151. The fixing member 142 is formed in a shape of a substantially circular section and has a concave groove portion 142a formed along the circumference of the side surface thereof inserted into the guide slot 151 and formed with an upper protrusion 142b and a lower protrusion 142b 142c are fixed to the upper and lower surfaces of the connecting block 150, respectively. The guide slot 151 is open at one end thereof so that the fixing member 142 can be easily attached and detached.

Hereinafter, the operation of the above-described scribing head lifting device in the first embodiment will be described.

6 is a cross-sectional view taken along line B-B 'of FIG. 6, FIG. 8 is a sectional view taken along the line C-C' of FIG. 7, 6 is a functional cross-sectional view of an inventive scraping head platform.

First, as shown in FIG. 6, the scribing head 120 is installed vertically up and down from the base 110 by a guide member 130. The actuator 140 is fixed to the base 110 in a vertical direction and the drive shaft 141 extending and retracted from the body is fixed to the connection block 150 fixed to the scribing head 120. In this state, when the actuator 140 is driven and the drive shaft 141 is expanded and contracted, the scribing head 120 moves up and down in the vertical direction along the expansion and contraction direction.

7 and 8, the fixing member 142 has a concave groove 142a at the center thereof, which is connected to the connecting block 150, The upper end protrusion 142b and the lower end protrusion 142c of the fixing member 142 are supported on the upper and lower surfaces of the connecting block 150 so as to restrict the movement in the vertical direction, Whereas it is slidable in the longitudinal direction of the guide slot 151. [

That is, in the assembled state of the fixing member 142 and the connection block 150, a coupling force acts in the vertical direction at the connection portion between the guide slot 151 and the groove portion 142a. Therefore, when the actuator 140 is driven, The vertical driving force applied to the fixing member 142 can be transmitted to the fixed scribing head 120 side connected to the connecting block 150. [

Particularly, when at least one of the guide member 130 and the driving shaft 141 of the actuator 140 is inclined so that the angle between the guide member 130 and the actuator 140 is not parallel, the gap between the driving shaft 141 of the actuator 140 and the guide member 130 is different at the driving start position and the driving end position of the actuator 140 as shown in FIG.

The driving operation in this state will be described in detail as follows.

9, the scribing head 120 is vertically movably mounted on the base 110 through a guide member 130, and the base 110 and the scribing head 120 The driving shaft 141 of the actuator 140 provided between the driving shaft 120 and the driving shaft 120 is extended or contracted to vertically move.

However, as described above, when the fixing position of the actuator 140 is not horizontal due to the assembly tolerance or the like, particularly when the gap at the raised position is narrow and the gap at the lowered position is not 9A, when the drive shaft 141 of the actuator 140 is contracted and raised, the distal end portion of the drive shaft 141 and the distal end portion of the guide member 141 are inclined at a predetermined angle? The gap between the distal end of the drive shaft 141 and the guide member 130 is widened when the distance between the drive shaft 141 and the drive shaft 141 is narrowed as shown in FIG.

That is, the driving shaft 141, which is disposed between the scribing head 120 and the base 110, moves up and down in a vertical direction while maintaining a constant gap therebetween, 110). Since the fixing member 142 connected to the driving shaft 141 is slidably coupled in the horizontal direction within the guide slot 151 of the connection block 150, the driving shaft 141 and the guide member 130 It is possible to prevent the driving shaft 141 from being stuck between the scribing head 120 and the base 110 even if the gap between the scribing head 120 and the base 110 is narrowed or widened.

According to the present invention, since the fixing member 142 connected to the drive shaft 141 slides in the horizontal direction in the guide slot 151 of the connection block 150 and compensates for the distance difference in the horizontal direction, Since the scribing head 120 can be smoothly moved up and down even if the guide member 130 and the drive shaft 141 of the actuator 140 are not parallel to each other due to deformation or the like, It is possible to prevent an excessive impact on the substrate.

The scope of the present invention is not limited to the above-described embodiments, but may be embodied in various forms of embodiments within the scope of the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
