Dürr has introduced its next-generation of painting robot: the new Ecopaint Robot. With its greater kinematic freedom, the EcoRP E043i model with its seven-axis kinematic system enlarges the work zone and can eliminate the need for a linear displacement rail. This can significantly reduce investment and maintenance costs in the paint booth. Another newly developed product, the EcoRCMP2 robot control, is a key module of the Smart Factory.
Conventionally, paint robots are usually equipped with six axes. A displacement rail in the booth wall ensures that the robot can move parallel with the car body in the paint booth and thereby reach all car body areas. The new Dürr robot has now been equipped with a seventh rotatory axis. This significantly increases flexibility and versatility,said Dr. Hans Schumacher, President and CEO of Dürr Systems AG.
The seventh axis is directly incorporated into the robot’s kinematic chain, thereby increasing the kinematic freedom. Particularly in interior painting, this improves access to many areas and avoids collisions with the vehicle. Thanks to the new control system, the 3rd-generation Dürr robot moves along the car body with harmonious painting paths.
In most stop-and-go applications and in many line-tracking applications, it is possible to dispense with the complex displacement axis now in use.
The six-axis variants are still available in the product range, alongside the highly flexible seven-axis robot. Apart from the missing seventh axis, they are identical to the seven-axis robot and are used with or without displacement axis. The EcoRP E/L133i robots operate either on a top- or bottom-mounted rail. In addition to painting, they also serve as lid openers in interior painting. Paint robots of this new generation can be placed anywhere. For example, they can be installed on the floor, wall, ceiling or at an angle in the paint booth.
The Dürr robot family benefits from its modular design in production and maintenance. All equipment variants can be built based on a basic manipulator. Identical components are supplemented with a few type-specific components. For example, the six- and seven-axis models differ only in the design of lower robot arm 1. This low level of complexity and the uniform component design throughout reduce warehousing costs and simplify maintenance work.
New Scara robots (EcoRP L030i/L130i) as door openers with extended Z-stroke complete the new product line. The robots feature a newly developed swivel head with optional tool cleaner, which Dürr is optionally offering. Its compact, flow-optimized design predestines the Scara robot for installation in paint booths. The door opener can be installed as a standard or mobile version on a compact interior rail at different heights. This rail was designed with a robust guide system to cope with the harsh conditions in the paint booth, and it can move one or two Scara robots.
Dürr’s third-generation robot is controlled by another newly developed product, the EcoRCMP2 process and movement control system. Much smaller control panels with modular control and drive components, new motors with more power to spare and a digital encoder interface, as well as an integrated safety control system for safe monitoring of the working area and speed, stand for an all-new generation of paint robots based on Dürr’s Smart Factory concept. This control platform combines numerous sensors and actuators belonging to the paint robot and the superordinate maintenance or control systems. An integrated interface makes the robot “cloud-ready” and provides all relevant data to meet current and future demands in the Industry 4.0 environment.
