Brittle material base board parting tool and brittle material base board supporting fixture

Abstract

The invention refers to a brittle material base board parting tool and a brittle material base board supporting fixture. The parting tool comprises a supporting clamp (1) provided with a groove (3) on a surface used for inserting an end part (W ') of a substrate (W); and a clamp (2) used for clamping and keeping the substrate (W) under the condition of projecting the end part (W ') of the substrate (W) which includes lineation and should be disconnected. The clamp (2) includes a first panel(8), a second panel (9), and an intermediate panel (11) between the panels (8,9) and the substrate (W). The intermediate panel (11) includes elastic materials; a left and ring width (L1) of the intermediate panel (11) is smaller than a left and right width (L2) of the substrate (W); an area (L3) without stacked intermediate panels (11) are left on left and right ends of the clamped substrate (W).

Description

technical field [0001] The invention relates to a cutting tool for brittle material substrates such as ceramics. In particular, the present invention relates to a simple cutting tool for manually cutting a brittle material substrate (hereinafter, simply referred to as "substrate") on which scribe lines (grooves) have been formed in a previous step. Background technique [0002] Conventionally, a method is known in which scribing equipment such as a cutter wheel (also referred to as a scribing wheel) or a laser beam is used to form scribing lines perpendicular to each other in the X direction and Y direction on the surface of a substrate, and then, from the scribing line The substrate is cut into unit substrates by applying an external force to the surface on the opposite side of the substrate, or bending the substrate, as disclosed in Patent Document 1, Patent Document 2, and Patent Document 3, for example. [0003] In addition, various methods have been conventionally know...

AI Technical Summary

Problems solved by technology

Therefore, a frame for lifting and lowering the cutting rod, a driving source for lifting and lowering, and a suction mechanism or a pressing member for stably holding the substrate on the table are required, which increases the size of the device and becomes expensive.

In addition, it is necessary to perform various initial settings of the operating parts such as the positioning of the substrate on the table, the feeding pitch, and the pressing pressure of the cutting lever when the device is first operated, and it is not suitable for cutting a small number of substrates (that is, it is not a standard for mass production). substrates other than products, etc.)
