Abstract

The present invention has been made in view of the fact that the position at which the scribing is formed deviates from the problem due to the movement of the scoring wheel in the direction of the pin axis, and the object of the present invention is to provide a stable position for forming the scribing and which does not occur as expected. A scribing device and a retainer unit that deviate from the position.

The scribing device 1 is configured such that the pin holes 64a, 64b formed in the holding portions 62a, 62b of the retainer 60 are formed at positions different from each other in the traveling direction R, and the pin 50 is opposed to and in the horizontal plane H. The direction R is orthogonal to the direction B. Therefore, if the scribe line is formed, the side surface 42a of the scribe wheel 40 is moved and brought into contact with the holding wall 65a, so that the movement along the pin 50 is regulated.

Description

Marking device and holder unit

The present invention relates to a scribing device and a holder unit used for forming a scribe line on a surface of a brittle material substrate in the division of a brittle material substrate such as a glass substrate.

When a brittle material substrate such as a glass substrate is divided into a desired size, a scribing device is generally used. The scribing device is used by mounting a scoring wheel on a holder for holding a scoring wheel. Further, the scribing wheel is held between the holding portions (holding grooves) by inserting a cylindrical pin into a pin hole formed in the holding portion of the retainer and a through hole formed in the side surface of the scoring wheel.

Further, the scribe wheel attached to the holder is rotatably held, and the scribe line is formed on the brittle material substrate by advancing while rotating on the surface of the brittle material substrate. Further, as the scribing device as described above, for example, there is a scribing device described in Patent Document 1.

The scribing wheel mounted on the retainer is required to form a scribe line as described above, and needs to be rotated in the retaining groove. Thus, the width of the retaining groove is somewhat wider than the thickness of the scoring wheel, ensuring that a gap is left between the scoring wheel and the retaining portion. Specifically, the thickness of the scoring wheel is 0.65 In the case of mm, the width of the holding groove is about 0.02 mm wide. Thus, since there is a gap between the scoring wheel and the holding portion, the scoring wheel train is held in a rotatable manner.

On the other hand, the scoring wheel can move about 0.02 mm along the pin in the retainer groove due to the gap. Therefore, when the scribing is formed, since the scribing wheel moves in the pin axis direction, the position at which the scribing is formed is unstable, and in the prior scribing device, there is a problem that the scribing is deviated from the desired position.

The present invention has been made in view of the fact that the position of the scribing is deviated from the problem due to the movement of the scribing wheel in the direction of the pin axis as described above, and the object of the present invention is to provide a stable position for forming the scribing without any desired A scribing device and a retainer unit that deviate from the position.

Further, when the scribe line is formed on the surface of the brittle material substrate 15 by using the scribing device 1, the scribing wheel 40 is rotated in the direction of the arrow R shown in the drawing of Fig. 2 or the like. Further, the scribing device 1 may have the following configuration: the retainer joint 21 is not used, and the retainer unit 30 itself includes the rotating shaft 23 and the bearings 24a and 24b.

The scribing wheel 40 is a disk-shaped member formed of, for example, sintered diamond or cemented carbide. Further, a through hole 41 for the supply pin shaft 50 to penetrate the scribing wheel 40 is formed at the center of both side faces 42a and 42b of the disc. Further, a V-shaped blade forming a ridge line at the scribing wheel 40 is formed on the outer peripheral portion. Further, the scribing wheel 40 of the present embodiment has a thickness of about 0.65 mm, an outer diameter of about 2.0 mm, a through hole 41 having a diameter of about 0.8 mm, and a blade edge angle of about 130°.

The pin shaft 50 is a cylindrical member formed of, for example, sintered diamond, a cemented carbide, or the like, and has a tip end 51 having a pointed shape at one end. Further, the pin shaft 50 of the present embodiment has a diameter of about 0.8 mm.

The holder 60 includes a body portion 61 made of stainless steel or carbon tool steel. As shown in FIG. 2(B), the main body portion 61 has a trapezoidal shape in which the width is narrowed toward the lower end in a side view. Further, the trapezoidal portions of the main body portion 61 are respectively formed with holding portions 62a and 62b, and a holding groove 63 is formed between the holding portions 62a and 62b. Further, although the holder 60 is configured by the main base portion 61, the main body portion 61 may be formed by fixing the two base materials each having the holding portions 62a and 62b, for example, in the following configuration.

Pin holes 64a and 64b through which the pin shaft 50 is inserted are formed in the holding portions 62a and 62b. Further, the details of the positions at which the pin holes 64a, 64b are formed will be further described below. The side surface 42a of the scoring wheel 40 opposes the holding portion 62a, and the side surface 42b faces the holding portion 62b.

The contact area of 165a is increased. Further, since the inclination angle of the holding groove 163 and the angle between the side surface of the scribing wheel 140 and the traveling direction R are made uniform, the side surface 142a side of the scribing wheel 140 is in surface contact with the holding wall 165a.

Further, the hook portions 381a and 381b are provided to be slightly offset from the same line in the traveling direction R.

Thus, the retainer unit 330 is slightly inclined as shown in Fig. 5(B) by the elastic force of the spring member 380. Since the retainer unit 330 is inclined, the pin 350 is also inclined with respect to the direction B orthogonal to the traveling direction R.

If a scribe line is formed on the surface of the brittle material substrate 15 by using the scribing device 1, the side surface 342a side of the scribing wheel 340 moves in the direction of the holding wall 365a, and comes into contact with the holding wall 365a. Therefore, the gap between the side surface 342a and the retaining wall 365a is zero, so that the movement of the row wheel 340 along the pin 350 is regulated at the time of forming the scribing.

Therefore, the magnet 481b provided in the holder unit 430 is attracted by the magnet 480, and the holder unit 430 is slightly inclined as shown in Fig. 6(B). Since the retainer unit 430 is inclined, the pin 450 is also inclined with respect to the direction B orthogonal to the traveling direction R.

If a scribe line is formed on the surface of the brittle material substrate 15 by using the scribing device 1, the side surface 442a side of the scribing wheel 440 moves in the direction of the holding wall 465a, and comes into contact with the holding wall 465a. Therefore, the gap between the side surface 442a and the retaining wall 465a is zero, so that the movement of the row wheel 440 along the pin 450 is regulated at the time of forming the scribing.
