Clean room robot

ABB has upgraded its IRB 6640 robot to create a ‘clean room’ version. Working in close cooperation with strategic partners from the photovoltaic industry, the project was undertaken in response to the strict specifications for thin film production processes used in solar module manufacturing, where cleanliness is a critical factor. The new clean room version of the IRB 6640 meets all necessary process and clean room specifications for the industry. The IRB 6640 clean room robot meets the stringent class 5 clean room specifications.

ABB clean room robots have three paint layers: a prime coat, a white paint layer and a clear top coat. Screws and inspection panels are covered with plastic prior to painting, which is subsequently removed when the paint dries. Some screws and panels are then protected again using removable covers, which facilitates cleaning. Inspection panels are not painted. Some of the cables are installed in an enclosed cable carrier, which enables them to be properly transported and at the same time prevents worn areas — even those that are not visible — from being exposed. Any areas that could potentially cause contamination are sealed at the factory using metal plates. The clean room robots are cleaned before they are shipped to customers and are protected by a double layer of plastic. The first layer is removed just outside the clean room to prevent any contaminants from entering. The second layer of plastic is removed inside the clean room to ensure compliance with strict cleanliness specifications.
