Description

Dash head and scribing device

The present invention relates to a scribing head having a cutter wheel (also referred to as a scoring wheel) for processing a scribing (cutting groove for cutting) on a surface of a brittle material substrate such as glass, and a scribing head using the scribing head Line device.

In the prior art, a scribing device is known which is attached to a surface of a brittle material substrate (hereinafter simply referred to as "substrate"), and is processed by a cutter wheel along a predetermined scribe line (see, for example, Patent Document 1 and Patent Document 2). .

Typically, the cutter wheel is supported by a retainer that is mounted to a retainer joint of the scribing head. Further, in the past, a device configured to exhibit a so-called "backward tilting effect" has been used, and the "backward tilting effect" is applied to cause the scribing head to travel, and the cutter wheel is always returned to the traveling direction line (for example, Refer to Patent Document 3 and Patent Document 4).

Fig. 3 is an explanatory view showing a mounting structure of a conventional cutter wheel having the above-described "rearward tilting effect".

The holder 22 holding the cutter wheel 21 at the lower end is rotatably attached to the holder joint 25 of the scribing head 24 via the vertical mounting shaft 23. The grounding point of the cutter wheel 21 is at a position shifted by a distance S1 from the line L3 obtained by extending the axis of the vertical mounting shaft 23 to the rear side in the traveling direction of the scribing head 24. Therefore, when the scribing head 24 is moved, the torque that follows the line in which the cutter wheel 21 is always returned to the traveling direction is exerted, and the straightness of the cutter wheel can be obtained.

The straightness of the cutter wheel achieved by the "backward tilting effect" described above varies depending on the amount of shift. In addition, depending on the moving speed of the cutter wheel, when the offset is large, the straightness is improved, but the vibration is weaker with respect to the left and right, and it is easy to travel from the direction of the scribing head. The line swings to the outside.

On the other hand, in the handle shaft and the wheel of a bicycle or a motorcycle, a caster angle and a structure called a trail (also called a trail) are assembled. The back inclination angle, as shown in FIG. 4, refers to the inclination angle β of the rotation axis L5 of the handle shaft 26 with respect to the vertical line L4, and the so-called trajectory refers to the ground point P3 of the wheel 27 and the rotation axis of the handle shaft 26. L5 is extended to a distance T1 between the points P4 obtained by the same horizontal line as the above-mentioned ground point P3. The larger the inclination of the handle shaft 26, the longer the trajectory (T1) becomes, the straightness is stabilized, but the handle operation becomes dull.

It is an object of the present invention to provide a scribing head which can improve the straightness while suppressing the swing of the cutter wheel to the right and left, and the use of the scribing, in consideration of the above-described aspect, by combining the above-described offset and trajectory. Head line device.

In order to solve the above problems, in the present invention, the following technical means are employed. That is, the present invention is a scribing head having a cutter wheel that is pressed against the surface of the substrate while being relatively moved, thereby processing a scribing line on the surface of the substrate, the scribing head including: a retainer, the lower portion Having a cutter wheel; a retainer joint that supports the retainer in a manner rotatable about the mounting shaft via a mounting shaft disposed on an upper portion of the retainer; and a support member that can hold the retainer joint Hold up and down; and set as follows: above installation The shaft system is formed to be inclined with respect to a vertical line toward the rear side in the traveling direction of the scribing head, and the wheel axle of the cutter wheel is disposed in a traveling direction of the scribing head with respect to a line extending from an axial center of the mounting shaft. The position of the rear side offset.

Furthermore, the present invention is also characterized in that the scribing device is configured to include the scribing head, and the scribing head is held by the beam of the frame so that the cutter wheel of the scribing head is pressed against the platform. The surface of the upper substrate is relatively moved along the surface of the substrate.

Preferably, in the present invention, the diameter of the cutter wheel is 1 to 3 mm, and the inclination angle of the axis of the mounting shaft and the vertical line is 10 to 25°, and the axle of the cutter wheel and the axis of the mounting shaft are The offset of the obtained line is 1 to 4 mm, and the amount of the track where the line of the cutter wheel with respect to the substrate and the line obtained by extending the axis of the mounting shaft intersects the substrate is 2 to 5 mm.

According to the present invention, the straightness of the cutter wheel is improved by the trajectory generated by tilting the mounting shaft of the retainer, and the degree of freedom of rotation is limited as compared with the case where the tilted mounting shaft is vertically mounted, so the straightness is improved. Stable, it can effectively suppress the sway caused by vibration and the like.

Further, since the wheel shaft of the cutter wheel is disposed at a position shifted toward the rear side in the traveling direction of the scribing head with respect to the axis extending the axis of the inclined mounting shaft, the amount of the trajectory can be extended according to the offset amount, and further Improve straightforwardness.

Further, the pressing of the cutter wheel at the time of scribing is different from that of the conventional two-wheeled vehicle, and is applied vertically at the center of the cutting edge of the cutter wheel, so that the effect of the pressure control of the cutter wheel can be easily performed.

Hereinafter, details of the scribing head of the present invention and the scribing apparatus including the scribing head will be described based on the embodiments shown in FIGS. 1 and 2.

Fig. 1 is a view showing a scribing apparatus of the present invention, which is provided with a stage 1 on which a substrate W is placed and held. A plurality of air suction holes (not shown) are provided on the surface of the platform 1, and communicate with an air suction source (not shown) such as a vacuum pump provided outside.

Further, the stage 1 is movable along the horizontal track 2 in the Y direction (the front and rear directions in Fig. 1), and the screw shaft 3 that is rotated by a motor (not shown) is driven. Further, the platform 1 is rotatable in a horizontal plane by a rotary drive unit 4 having a built-in motor.

The frame 7 having the support columns 5, 5 provided on both sides of the platform 1 and the beam (crossbar) 6 extending horizontally in the X direction is disposed across the platform 1. The guide beam 8 is horizontally extended in the X direction, and the guide head 8 is provided with a scribing head 10 of the present invention which is movable in the X direction by the motor 9.

As shown in detail in FIG. 2, the scribing head 10 includes a retainer 13 having a cutter wheel 11 at a lower portion and a mounting shaft 12 at an upper portion thereof, and a retainer joint 15 that is freely rotatable about the mounting shaft 12. In this manner, the retainer 13 is supported via the mounting shaft 12 and the bearing 14; and a support member 16 that holds the retainer joint 15 up and down.

The holder joint 15 can be raised and lowered together with the holder 13 by a lifting mechanism (not shown) such as a hydraulic cylinder provided in the support member 16. Further, the cutter wheel 11 attached to the holder 13 can use a cutter wheel having a diameter of 1 to 3 mm.

The mounting shaft 12 of the retainer 13 is formed at an inclination angle α with respect to the vertical line L1 toward the traveling direction of the scribing head 10 (the direction of the arrow in FIG. 2). The inclination angle (back inclination angle) α is preferably set to 10 to 25°.

Further, due to the inclination of the mounting shaft 12, a trajectory is generated between the ground point P1 of the cutter wheel 11 to the ground point P1 of the substrate W and the point P2 at which the axis L2 of the mounting shaft 12 is extended to the substrate W. T. The length of the track T is preferably set to 2 to 5 mm.

Further, the wheel shaft 11a of the cutter wheel 11 is provided at a position shifted by a distance S from the line L2 obtained by extending the axis of the inclined mounting shaft 12 toward the rear side in the traveling direction of the scribing head 10. The offset amount, that is, the interval S is preferably set to 1 to 4 mm.

In the present embodiment, when a cutter wheel having a diameter of 2 mm is used, and the inclination angle α of the attachment shaft 12 is set to 17°, and the offset interval S is set to 2.5 mm, the length of the trajectory T becomes 2.92 mm. Therefore, the trajectory T is formed to be longer than the displacement of the mounting shaft 12 by 2.5 mm.

The scribing device moves the scribing head 11 against the surface of the substrate W while moving the scribing head 10 in the direction of the arrow in FIG. 2 to process the scribing on the surface of the substrate W.

At the time of the machining, the straightness of the cutter wheel 11 is improved by the trajectory T generated by tilting the mounting shaft 12, and the degree of freedom of rotation is limited as compared with the case where the tilted mounting shaft 12 is vertical, so the straightness is improved. Stable, it can effectively suppress the sway caused by vibration and the like.

Further, the wheel shaft 11a of the cutter wheel 11 is disposed at a position shifted from the line L2 which is extended by the axial center of the inclined mounting shaft 12 to the rear side in the traveling direction of the scribing head 10, and thus can correspond to the interval S. The amount of the above-mentioned trajectory T is extended, so that the straightness can be further improved.

Further, the pressing of the cutter wheel 11 at the time of scribing is different from the handle shaft of the two-wheeled vehicle described at the beginning, and is applied perpendicularly to the center position of the cutting edge of the cutter wheel 11, so that the pressure control can be easily performed.

The representative embodiments of the present invention have been described above, but the present invention is not limited to the structures of the above-described embodiments, and may be modified and changed as appropriate without departing from the scope of the claims.
