The invention relates to the technical field of displaying, and particularly to a detecting device of a vacuum aligner system. The detecting device of the vacuum aligner system comprises the components of: a vacuum aligner chamber which is communicated with a plurality of vacuum pipes; a supplying gas source which is communicated with the vacuum aligner chamber; a liquid crystal separation discharging device which is communicated with the vacuum pipes and is used for discharging the liquid crystal that residues in the vacuum pipes; and a pipe detecting device which is used for acquiring gas source amount at connection parts of the vacuum pipes for determining whether leakage occurs in the vacuum pipe. The detecting device of the vacuum aligner system provided by the invention comprises the liquid crystal separation discharging device and the pipe detecting device. The detecting device of the vacuum aligner system has the functions of: effectively separating the liquid crystal which resides in the vacuum pipes, improving vacuum degree and safety in the vacuum chamber, effectively detecting micro leakage in the vacuum pipes, preventing micro leakage, improving detection efficiency, and furthermore improving vacuum aligning efficiency.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a detection device for a vacuum box alignment system. Background technique [0002] In the liquid crystal panel manufacturing process, the vacuum bonding process is an important step in the whole process. Its specific operation includes in a closed vacuum chamber, the array substrate and the color filter substrate are respectively adsorbed by the upper fixing plate and the lower fixing plate, and the upper fixing plate and the lower fixing plate are respectively adsorbed. The fixed plate and the lower fixed plate move towards each other to press the array substrate and the color filter substrate together to form a liquid crystal panel. [0003] The vacuum degree of the vacuum box machine will have a greater impact on the quality of the product and the utilization rate of the equipment. At present, the vacuum degree of the vacuum box-to-box equipment is detected by a simple vacu...
