COATING DEVICE

摘要

A coating device comprises a base, a mounting bracket mounted to the base by a driving mechanism, a coating unit which comprises a supporting rack mounted to the mounting bracket and a nozzle mounted to the supporting rack, and the coating device further comprises a detecting device mounted to the supporting rack, which detects information about a distance between the nozzle and a surface of the substrate to be coated and information about an obstacle on a substrate in an advancing direction of the nozzle; a control unit, which controls to keep the distance to be a preset distance based on the detected distance information, and which controls to stop operation of the nozzle where an obstacle is detected on a region on the surface of the substrate between the detecting device and the nozzle.

1. A coating device, comprising a base, a mounting bracket mounted to the base, a coating unit which comprises a supporting rack mounted to the mounting bracket and a nozzle mounted to the supporting rack, the coating device further comprising
a detecting device mounted to the supporting rack, which detects information on a distance between the nozzle and a surface of a substrate to be coated and on an obstacle on a substrate in an advancing direction of the nozzle; a control unit connected with the detecting device, which controls to keep the distance between the nozzle and the substrate surface to be a preset distance by means of a driving mechanism based on the distance information obtained by the detecting device, and which controls to stop operation of the nozzle by the driving mechanism where the detecting device detects that there is an obstacle in a region on the surface of the substrate between the detecting device and the nozzle.
