Abstract: An automatic vehicle body sanding system operated in a painting factory includes a painting inspection device configured to detect a defective position (NG Point) by analyzing a 2D image of a vehicle body for which an intermediate process has been completed taken with a camera, and display the defective position on a 3D vehicle body drawing. The automatic vehicle body sanding system includes a robot having a multi-joint structure on which at least one of a 3D scanner, a sanding tool, and a dust absorber required for sanding work is mounted. Further, the automatic vehicle body sanding system includes a server configured to match the defective position of the vehicle body detected by the painting inspection device and 3D scan data of the vehicle body scanned by the 3D scanner with a 3D vehicle body drawing shape on a simulator.

Abstract: A system includes an air conditioner in each zone of a painting process line supplying heated air according to temperature/humidity stabilization conditions for a painting process of each zone of a spray booth; a controller transmitting operation information related to the air conditioner including temperatures and humidities of outdoor air flowing into the air conditioner and indoor air inside each zone of the booth and operating the air conditioner when a control value is received; and a server learning operation information history of the air conditioner collected through the air conditioning controller to accumulate the learned data in a database and extracting the control value for each of controllers of the air conditioner according to an initial operation condition of the air conditioner from the learned data in the database to control each of the controllers of the air conditioner for a predetermined time period based on the extracted data.

Abstract: An exemplary system for controlling electrodeposition coating for electrochemically forming a coating film on a coating object in an electrodeposition tank storing electrodeposition solution includes, a positive electrode configured to apply a positive electrode voltage to a positive electrode disposed in the electrodeposition tank, a negative electrode configured to apply a negative electrode voltage to the coating object transferred by a hanger, and an electrodeposition controller configured to electrochemically deposit the coating film on an external surface and an internal surface of the coating object by applying the positive electrode voltage to the positive electrode and the negative electrode voltage to the negative electrode, where the electrodeposition controller may be configured to control voltage, current, and pulse in multi-stages over time from a dip-in time point to a draw-out time point of the coating object into and from the electrodeposition tank.

Abstract: A system includes is provided to include an air conditioner in each zone of a painting process line supplying heated air according to temperature/humidity stabilization conditions for a painting process of each zone of a spray booth. A controller transmits operation information of the air conditioner including temperatures and humidities of outdoor air flowing into the air conditioner and indoor air inside each zone of the booth and temperature/humidity stabilization condition values for each zone of the booth. A server extracts stabilization time of the operation information equal to current operation information in a database in which the stabilization time required for temperature and humidity of each both zone to reach the condition values is stored and applies operation command for the air conditioner to the controller at operation schedule time derived by calculating the stabilization time backward from a time when a vehicle arrives at each booth zone.

Abstract: An apparatus and a method are used for controlling an air conditioning system for automotive body painting to regulate temperature and humidity in a paint booth based on difference between enthalpy of outside air and enthalpy of supply air. The apparatus includes a first temperature sensor measuring temperature of outside air, a first humidity sensor measuring humidity of outside air, a second temperature sensor measuring temperature of supply air, a second humidity sensor measuring humidity of supply air, and a controller calculating first enthalpy based on the temperature and humidity of the outside air, calculating second enthalpy based on the temperature and humidity of the supply air, and controlling the air conditioning system to regulate the temperature and humidity of the supply air when difference between the first enthalpy and the second enthalpy is below or exceeds a reference enthalpy range.
