Embodiment Construction

[0043] Figure 1A , Figure 1B It is a schematic view of the scribing device according to this embodiment viewed from the side. As shown in these figures, a pair of left and right pillars 10a, 10b are attached to a base 11 and blocks 12a, 12b. The upper portion between the pillars is provided in parallel with movable guide pillars 13a, 13b, and the movable guide pillars 14a, 14b are arranged in parallel below. The movable guide posts 13a, 13b and 14a, 14b each move the lateral slide members 15, 16 in the x-axis direction (left-right direction). The horizontal slide members 15, 16 are respectively provided with vertical slide members 17, 18 for moving the scribing head in the z-axis direction (up-down direction). A scribing head 19 is provided at a lower end portion of the vertical sliding member 17 . A scribing head 20 is provided at an upper end portion of the vertical sliding member 18 . Marking head 19,20 is to keep marking wheel person at its front end.

Abstract

The invention provides a marking device which can prevent the direction contact of marking wheels when the marking wheels mark a glued substrate from top to bottom at the same time. The two sides of the marking wheels (22, 32) of upper and lower marking heads (19, 20) are provided with roller pairs (23, 24) (33, 34). The distance between the front end of the roller and the front end of the marking wheel is less than half of the thickness of the glued substrate. In such a manner, even the glued substrate thickness data input or operation is wrong, the rollers and the glued substrate can contact before the contact of the knife points of the marking wheels, so the knife points of the marking wheels can not contact with each other.

Description

technical field [0001] The present invention relates to a scribing device for simultaneously scribing both surfaces of a bonded substrate or the like to which two brittle material substrates are bonded. Background technique [0002] A liquid crystal panel such as a liquid crystal display device has a structure in which two glass plates are bonded together. When cutting out a liquid crystal panel from a bonded substrate on which two glass plates are bonded, it is necessary to form scribe lines on the upper surface and the lower surface of the bonded substrate. Therefore, the scribing device of Patent Document 1 is known as a scribing device for simultaneously scribing lines on both surfaces. It performs scribing on both surfaces of a bonded substrate by moving a pair of scribing heads having scribing wheels at their tips in a direction parallel to the surface of the bonded substrate.
