Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment shown below is only an example for embodying the technical idea of ​​the present invention, and it is not intended that the present invention is specific to the embodiment. The present invention can also be applied to other embodiments included in the scope of the patent application.

[0036] [Embodiment 1]

[0037] At figure 1 A schematic diagram showing a scribing apparatus 10 according to Embodiment 1 is shown. The scribing apparatus 10 includes a mobile station 11 . Further, the moving table 11 is screwed with the ball screw 13, and the ball screw 13 is rotated by the drive of the motor 14, and can move in the y-axis direction along the pair of guide rails 12a and 12b.

[0038] On the upper surface of the moving table 11, a motor 15 is provided. The motor 15 rotates the upper stage 16 in the xy plane and is positioned at a predetermined an...

Abstract

The present invention provides a holder unit, a holder unit and a scoring device in which a holder, a scoring wheel, and a pin are integrated, which can improve the end surface strength of a broken brittle material substrate when the brittle material substrate has been scored. The holder unit (30) of the present invention is a holder unit (30) that integrates the holder (31), the marking wheel (40) and the pin (50). Since the pin (50) is rotatably arranged on pin holes (35a, 35b), and thus the present invention enables increased end face strength of brittle material substrates compared to holder units in which pins are arranged non-rotatably.

Description

technical field [0001] The present invention relates to a holder unit and a scribing device for forming scribing lines on the surface of a brittle material substrate. Specifically, the present invention relates to a holder, a holder unit in which a scoring wheel and a pin are integrated, and a scoring device including a joint portion to which the holder unit can be attached and detached. Background technique [0002] A scribing wheel is generally used in the breaking of brittle material substrates such as glass substrates. Specifically, the scribing wheel is pressed and rotated on the glass substrate to form scribing lines on the surface of the substrate, thereby generating cracks in the vertical direction from the surface of the substrate (scribing step), and then applying stress to the substrate to make the The vertical crack grows to the back surface of the substrate (fracture step), thereby performing the breaking of the brittle material substrate. [0003] When a scri...
