Abstract

The invention relates to a cutter wheel holder unit, by means of which a scribing wheel can be kept stably in position and the linearity of a scribed line is improved. According to the technical scheme of the invention, a scribing wheel (30) is in the form of a circular plate and the center of the scribing wheel (30) is provided with a through hole (31). The outer peripheral part of the circular plate is provided with a v-shaped cutter front end. A cutter wheel holder body (10) is provided with a holder groove (12) of a certain width and used for the insertion of the scribing wheel (30), and a pair of supporting parts (13, 14). Ball holders (17, 18) are inserted into the through holes (15, 16) of the supporting parts (13, 14). By means of a pair of balls (24, 25) and the ball holders (17, 18), the scribing wheel (30) is clamped into the holder unit in a freely rotating manner.

Description

technical field [0001] The present invention relates to a wheel holder unit for holding a scribing wheel for forming scribe lines on a brittle material substrate. Background technique [0002] A scribing device is used for scribing and breaking a brittle material substrate into a desired size. The scribing device includes a wheel holder unit on a scribing head facing the brittle material substrate. figure 1 , is a sectional view of a known wheel holder unit disclosed in Patent Document 1. The wheel holder unit 100 has a wheel holder body 110 , a scoring wheel 120 , and a pin 130 , and the scoring wheel 120 is attached to the wheel holder body 110 . [0003] Such as figure 1 As shown, a holder groove 111 and a pin hole 112 are formed at the lower part of the cutter wheel holder 110 . The scoring wheel 120 is a disc-shaped member, has a through hole penetrating through the center of two circular side surfaces, and has a V-shaped blade tip along the outer periphery of the s...
