Abstract

The invention relates to the field of liquid crystal substrate production and manufacturing, and discloses a liquid level measuring device, a kiln furnace and a liquid level measuring method. The liquid level measuring device is at least used for measuring the liquid level of high-temperature glass of the kiln in liquid crystal substrate manufacturing, and the liquid level measuring device comprises a laser transmitter and a receiving panel; the laser transmitter is used for transmitting first laser into the kiln furnace through a laser inlet formed in the upper part of the front wall of the kiln furnace; the receiving panel is used for receiving the second laser reflected back from the liquid level of the liquid of the kiln furnace through a laser outlet formed in the rear wall of the kiln furnace; wherein the receiving panel is provided with length measuring scales on a receiving track line of the second laser. The technical problems that due to the fact that the environment temperature of high-temperature liquid detection is high, electronic equipment for liquid level measurement is prone to damage, manual installation and debugging operation is limited, an electronic measuring device is high in cost, and the liquid level height of high-temperature liquid cannot be monitored in time after damage are solved.

Description

technical field [0001] The invention relates to the field of liquid crystal substrate production and manufacturing, in particular to a liquid level measuring device, a kiln and a liquid level measuring method. Background technique [0002] In the production process of liquid crystal substrate glass, the control of the high temperature glass liquid level in the kiln is very important. In order to provide immediate and accurate liquid level parameters for the downstream process, so as to better control its flow rate, most of the high-temperature liquid level measuring devices in the existing technology use radioactive materials in the control system, which poses certain safety hazards to the human body. At the same time, such measurement systems are very expensive. Due to the high-temperature liquid measurement environment, the measurement equipment is close to the high-temperature glass liquid transmission channel, and the aging speed is very fast. In addition, its control s...
