Problems solved by technology

If the wheel and the rotation shaft of the wheel are separated, the rotation of the wheel may fluctuate due to the gap between the shaft hole of the wheel and the rotation shaft, and the wheel may not rotate stably.
It is difficult to form a good score line when the rotation of the wheel is unstable

Embodiment Construction

[0029] Hereinafter, with reference to the accompanying drawings of embodiments of the present invention will be described. Note that, for convenience, in each of the figures labeled with mutually orthogonal X axis, Y axis and Z axis. Z-axis is parallel to the vertical direction. Above and below, respectively, the Z-axis positive, and Z-axis negative direction corresponds.

[0030]

[0031] figure 1 In (a) is a diagram schematically showing a configuration of an application of the holder unit 50 of the scoring apparatus.

[0032] like figure 1 In (a), the scribing apparatus 110, the moving mechanism 20 and the support mechanism 30 having a scribe head. Scribing head 10 in the scribe line is formed by the substrate 30 supported by the support mechanism F. Moving mechanism 20 moves the scribe head 10 in the scribing direction (X-axis positive direction). The support mechanism 30 is placed on the surface of the substrate F, F for supporting the substrate. Further, the support means ...

Abstract

The present invention provides a cutter wheel capable of easily and firmly joining a wheel and a rotary shaft, and a holder unit equipped with the cutter wheel. A cutter wheel (200) is provided with awheel (210) having a rotary shaft (220), a shaft hole (211) into which a rotary shaft (220) is inserted, and a cutting edge (212) forming a scribe line on a substrate (F). Further, the rotation shaft(220) has a tapered portion (R1) formed at least at a portion thereof so as to extend from a diameter (L1) smaller than a diameter of the shaft hole (221) toward a diameter (L2) larger than a diameter of the shaft hole (221), and the rotation shaft (220) and the wheel (210) are integrated by press-fitting the tapered portion (R1) of the rotation shaft (220) into the shaft hole (211).

Description

Technical field [0001] The present invention relates to a cutter wheel for forming scribe lines in the surface of the substrate and having a cutter wheel holder unit. Background technique [0002] Conventionally, dividing brittle material substrate such as a glass substrate, a nose wheel pressing surface of the substrate while moving along a predetermined line to form a scribe line. Wheel rotating shaft and the wheel for the case where the sub-body, the rotation gap between the shaft hole and the rotary shaft of the wheel, the wheel becoming loose, the wheel may not be stably rotated. In the case of unstable rotation of the wheel, it is difficult to form a good scribe line. [0003] Accordingly, there is a cutter wheel, by integration of the rotary shaft of the wheel so as not to produce a gap between the shaft hole and the rotary shaft of the wheel. In such a cutter wheel in order between the shaft hole and the rotation shaft of the wheel no gap needs to be firmly engaged with t...
