Publication number: 20210094058Abstract: A plurality of painting zones is connected in series by a plurality of air exhaust ducts so as to allow air to flow through the painting zones. A paint mist in air having passed through a painting chamber of each painting zone is removed by a dry filter. Feedback control is performed on the temperature and the humidity of air in a second painting zone other than a third painting zone to which conditioned air from an air conditioner is supplied. Thus, it is possible to appropriately adjust the temperature and the humidity of each painting zone and avoid degradation of painting quality in each painting zone, while achieving downsizing of the entire system by not providing a recycling air conditioner on the route of an air flow passage.Type: ApplicationFiled: June 18, 2020Publication date: April 1, 2021Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keiichi FUJIWARA, Shinji Tani, Akira Numasato, Kazuki Tanaka

Patent number: 7220966Abstract: A system for detecting defects in paint coatings includes a temperature manipulation apparatus configured to change the temperature of a surface and a coating applied to the surface. The system may further include an infrared sensor for measuring the change in temperature (over time) of the surface and coating and a processor to compare the measured change in temperature of the surface and coating to an expected change of temperature (over time) in order to determine anomalies in the coatings. A self-referencing method of determining defects is also disclosed, wherein surrounding pixels are utilized as a reference in the detection process for calculating the change in temperature of each pixel. In addition, application of the inventive aspects to inspection of adhesion interfaces is also disclosed.Type: GrantFiled: November 12, 2004Date of Patent: May 22, 2007Assignee: Toyota Motor Manufacturing North America, Inc.Inventors: Kozo Saito, Mohammed I.
