Description

[0001] THIN TYPE CELL PANEL SCRIBING MACHINE [0002]

This invention relates to a cutting apparatus for scribing cutting lines on both sides without reversing a thin (thin plate) cell panel.

A method of scribing a cut line on both sides without reversing the liquid crystal panel is already known (see Patent Documents 1 and 2).

Japanese Patent Application Laid-Open No. 5-221672 Japanese Patent Application Laid-Open No. 2003-119043

However, according to the methods of Patent Documents 1 and 2, after the scribing line is scribed by the cutter on the upper surface of the lower table or the suction support panel (suction support panel) supplied to the upper surface of the first stage, Or the panel on the first stage is sucked and supported by the upper table or the lower surface of the second stage and then the cutting line is scribed by the cutter on the lower surface of the storage panel. This allows you to scribe the cut lines on both sides of the panel without reversing the panel.

However, when the panel on which scribing of the cutting line is completed on both sides is to be ejected by the next processing (for example, division), it is taken out by suction or human hand.

However, when the thickness of the panel is thick, it can be discharged so as not to affect the panel. However, according to the recent thinning of the panel, when the suction method is adopted when discharging the panel, So that the scribe line is divided or the scribe line is broken.

This is the cause of defective products.

It is also conceivable to increase the number of parallel arrangement of the suction panels (suction panels) to reduce the warpage of the panel. However, as the suction panel and the panel are in contact with each other, the panel surface is soiled, causing defective products due to contamination, Cleaning can be cumbersome and costly.

It is also conceivable to discharge it by the hand of a person so that an unreasonable force does not act on the panel.

However, if the panel slips on the table as it is discharged by the hand of a person, there arises a problem of damaging or scratching the plate surface of the panel.

Particularly, when the panel is divided, the panel is discharged and supplied to the next divided position. Therefore, the number of operations by the person is considerably increased, and the cutting position in the next process (adjustment of the cutting line with the brake bar Etc.), and it is difficult to obtain a product-size panel according to the division.

The object of the present invention is to provide a cutting apparatus for a thin plate cell panel in which the above problem is solved.
