Description

TESTING APPARATUS FOR FIXING AND TESTING A LCD PANEL}

According to the present invention, the inspection mechanism for fixing the LCD panel, in particular, the LCD panel is hypothesized on the positioning frame unit to determine its position, and the images photographed each time with the camera are all unified to the same size, so that the inspection module checks the quality. An inspection apparatus for fixing an LCD panel that is easy to compare.

The finished product of all LCD panels must include good and bad parts. Therefore, all manufacturers are screening for defective LCD panels by quality control personnel before the product is shipped so that the defective LCD panels are not distributed to the market and affect the credit of the manufacturers. Therefore, quality control personnel can say that they play a significant role in the manufacturing process of the product.

However, quality control personnel are usually prone to the following problems in the product inspection process.

1. The quality control agent checks the LCD panel with the naked eye by inspecting the LCD panel with the naked eye. If it is observed for a long time, it will cause eye fatigue and weaken the effect of quality management, affecting the product quality. Crazy

2. If there is a fine defect in the product, it is difficult to detect the defect with the naked eye, which greatly increases the error rate of the test result.

As described above, there are many problems with the conventional inspection method described above, and improvement is required.

The present inventors have focused on the problems derived from the above-described conventional inspection method, and as a result, have led to the development of an inspection mechanism for fixing the LCD panel of the present invention.

An object of the present invention is to capture an LCD panel image by fixing the LCD panel to be inspected to the positioning frame unit and adjusting the photographing mechanism on the base, and the photographed images are all unified to the same size, and the photographed image is inspected by the inspection module. The present invention provides an inspection apparatus for fixing an LCD panel, which can be transmitted to a computer to perform contrast comparison and analysis of quality.

Another object of the present invention is to provide an inspection mechanism for providing an adjustment plate on a positioning frame unit and fixing an LCD panel capable of placing and positioning LCD panels of different sizes on the positioning frame unit.

It is still another object of the present invention to provide a movable shielding plate capable of shielding the metal frame of the LCD panel in the positioning frame unit so as to clearly distinguish the boundary between the panel display area and the border, and to display the image of the metal frame.
