Problems solved by technology

[0012] This makes the substrate scribing device complex in structure and bulky in size, thus increasing high maintenance costs
[0013] In addition, the traditional method of positioning the scribing wheel on the substrate surface by controlling the torque of the servo motor may cause a difference between the actual position of the scribing wheel and the detected position, thereby reducing the position of the scribing wheel on the substrate surface. the accuracy of
[0014] In addition, adding a conductive metal piece to control the position of the scribing wheel requires a complex structure of the substrate scribing device, which further reduces the accuracy of the scribing wheel position

Embodiment Construction

[0029] Hereinafter, preferred embodiments of the present invention will be described in detail, examples of the invention are illustrated in the accompanying drawings.

[0030] like Figure 2 to Figure 4 As shown, the substrate scribing device according to this clear embodiment includes: a voice coil motor 10 that generates a linear force; an ascending / descending block 20 that moves up and down depending on the linear force generated by the voice coil motor 10; a scribing wheel holder 30 that sets At the lower portion of the ascending / descending block 20; and the scribing wheel 40, which is provided on the scribing wheel holder, scribing the substrate.

[0031] The voice coil motor 10 is disposed on a support plate 100 disposed above a stage (not shown) on which a substrate is placed. The voice coil motor 10 includes: a stator 11 fixed on the support plate 100 ; and a mover 12 arranged inside the stator 11 and moving up and down. The stator 11 has a cylindrical body. An ope...

Abstract

The invention provides a device for dividing a substrate used for flat panel displays into discrete substrates, comprising: a support plate; a magnetic force generating unit arranged on the support plate, using the current provided by the control unit to generate magnetic force to generate along the magnetic force The linear force in the direction of the unit length; the rising / falling block, fixed on the magnetic force generating unit, moves up and down by the linear force generated by the magnetic force generating unit; the scribing wheel, set on the rising / falling block, scribing the substrate; and the distance A measuring unit that senses the traveling distance of the ascending / descending block and transmits traveling distance information to a control unit that controls the operation of the magnetic force generating unit.

Description

technical field [0001] The present invention relates to an apparatus for scribing a substrate for a flat panel display, and more particularly, to an apparatus for dividing a substrate for a flat panel display into individual substrates. Background technique [0002] The substrate scribing device divides the substrate on which the pattern is formed into a plurality of separate substrates according to the size of each of the flat panel displays used for computers, communications, instruments or televisions. [0003] figure 1 is a drawing showing a conventional substrate apparatus used for scribing a substrate for a flat panel display. like figure 1 As shown, the conventional substrate device includes: a rising / falling block 1; a scribing wheel holder 2, which is rotatably arranged on the rising / falling block 1; and a scribing wheel 3, which is rotatably arranged on the scribing wheel holder 2 superior. [0004] The ascending / descending block 1 is provided on a support plat...
