Abstract: An inspection module is disclosed for inspecting a droplet from an ink jet head. The inspection module includes a sensor located under the ink jet head and measuring a distance between the droplet and the sensor in real time; a variable lens changing an operating distance based on the measured distance of the sensor; and a camera for capturing an image of the droplet. The inspection module further includes a droplet inspecting part inspecting the droplet image captured by the camera.

Abstract: Provided are a control unit that predicts the life of an inkjet head unit and maximizes its life to be used, and a substrate treating apparatus including the same. The control unit performs maintenance of an inkjet head unit for discharging a substrate treatment liquid onto a substrate and comprises a count module for counting the number of discharges for each nozzle of the inkjet head unit, a comparison module for comparing the number of discharges with a reference value to determine whether the number of discharges is equal to or greater than the reference value, and an evaluation module for evaluating whether a life of the inkjet head unit has reached a usable life based on whether the number of discharges of each nozzle is equal to or greater than the reference value.

Abstract: A static electricity visualization apparatus capable of visually identifying a measured level of static electricity is provided. The static electricity visualization apparatus comprises a photographing unit for generating a first photographed image obtained by photographing a measurement target at a first distance from the measurement target in a first mode, and generating a second photographed image obtained by photographing the measurement target at a second distance from the measurement target in a second mode, a static electricity sensor for measuring a static electricity level of the measurement target at the second distance from the measurement target, a processor for matching the second photographed image with the first photographed image, and an output unit for outputting a static electricity visualization image that visualizes a static electricity level measured by the static electricity sensor on the first photographed image, wherein the static electricity visualization image comprises a color corresponding to the static electricity level of the measurement target measured by the static electricity sensor at a position where the second photographed image matches on the first photographed image.

Abstract: The inventive concept provides a teaching method for teaching a transfer position of a transfer robot. The teaching method includes: searching for an object on which a target object to be transferred by the transfer robot is placed, based on a 3D position information acquired by a first sensor; and acquiring coordinates of a second direction and coordinates of a third direction of the object based on a data acquired from a second sensor which is a different type from the first sensor.
