Wheel holder of scriber

Abstract

The invention provides a wheel holder assembly of scriber for cutting brittleness substrate like glass. The assembly includes a wheel holder for forming a scribed line for cutting a brittleness substrate, and a linking unit aligned on the head part of the scriber which can link with the wheel holder detachably, and a magnet aligned on the linking unit or the wheel holder for fixing the wheel holder to the linking unit by employing magnetic force. The wheel holder links with the head part of scriber, therefore it helps to detachably replacing the wheel holder.

Description

technical field [0001] The present invention relates to a wheel holder assembly for a scriber and, in particular, to a wheel holder assembly for a scriber for cutting substrates made of brittle materials such as glass. Background technique [0002] Generally, a glass substrate used as a substrate of a display is first manufactured as a large-sized substrate, which is then cut into a plurality of small-sized individual substrates suitable for its use. [0003] The process of cutting brittle materials, such as glass substrates, generally includes: scribing the surface of the substrate using a diamond-tipped tool (which has a hardness greater than that of the glass substrate) to form cut lines on the substrate; Pressurize the substrate near the cutting line to cut the substrate along the cutting line. [0004] Specifically, the scribing process is a process of rotating a cutting wheel to form cracks at cut positions of the substrate. The cutting process is a process in which ...
