Problems solved by technology

[0003] In the previous manufacturing process, the liquid crystal storage device was placed upright, and the operator relied on the naked eye to judge when to replace the liquid crystal storage device. When judging, it is easy to have too much or too little liquid crystal left in the bottle, and the remaining is too much. If the liquid crystal storage device can be tilted at a certain angle during the manufacturing process, it will be beneficial to the concentration of the liquid crystal, reduce the amount of residual liquid crystal, and reduce the amount of residual liquid crystal in the liquid crystal. An automatic liquid level detection and alarm device is installed in the storage device to reduce errors caused by human judgment

Embodiment Construction

[0020] For being able to describe the present invention in detail, please refer to figure 1 As shown, the present invention is a liquid crystal residual warning system 12, which is mainly applied in the TFT-LCD industry. The liquid crystal residual warning system 12 includes a liquid crystal storage device 14, and there is a space in the liquid crystal storage device 14 for storing liquid crystals. Because in the Cell segment manufacturing process of TFT-LCD, the liquid crystal is taken out from the liquid crystal storage device 14 by means of a suction pipe 26 sucking the liquid crystal, and the liquid crystal system is constantly consumed in the manufacturing process, so the liquid crystal in the liquid crystal storage device 14 volume will continue to decrease.

[0021] exist figure 1 The sensing device in the embodiment includes a weight sensor 18 and an alarm 20; wherein, the weight sensor 18 and the alarm 20 are respectively arranged on a supporting device 16, and the ...

Abstract

The invention relates to a liquid crystal residue alarm system and a method thereof, in particular to a liquid crystal residue alarm system and a method for obliquely arranging a liquid crystal storage device on a supporting device. The method comprises the following steps: tilting and stably arranging the liquid crystal storage device on the supporting device, measuring liquid crystal residue by sensing equipment, and sending out an alarm signal when the liquid crystal residue is lower than a set value so as to prompt the replacement of the liquid crystal storage device.

Description

technical field [0001] The present invention mainly relates to a system and method for reducing residual liquid crystal, in particular to a liquid crystal residual warning system and method for obliquely setting a liquid crystal storage device on a supporting device. Background technique [0002] In the TFT LCD industry, liquid crystals are expensive. In the Cell process, how to reduce the amount of remaining liquid crystals in the liquid crystal storage device that cannot continue to be titrated is a major problem in the effective use of liquid crystals and cost savings. [0003] In the previous manufacturing process, the liquid crystal storage device was placed upright, and the operator relied on the naked eye to judge when to replace the liquid crystal storage device. When judging, it is easy to have too much or too little liquid crystal left in the bottle, and the remaining is too much. If the liquid crystal storage device can be tilted at a certain angle during the manu...
