Sealant coating equipment for liquid crystal panel and its coating method

A sealant coating equipment of a liquid crystal panel, comprising a nozzle, wherein the nozzle is used for sealant coating of a substrate required to be sealant-coated, characterized in that:

• the equipment further comprises a monitoring and detecting device;
• wherein when the nozzle performs sealant coating, the monitoring and detecting device is used to acquire instantaneously images after the sealant coating is performed by the nozzle, and determining if there are defects of the sealant coating according to acquired images, and recording location data of defective sealant coating when determining that there is the defective sealant coating;
• and
• wherein when the nozzle finishes the sealant coating, the monitoring and detecting device is further used to display images of the defective sealant coating and the location data of the defective sealant coating.
