Handling Robot for Hazardous Environments
Yaskawa Motoman’s explosion-proof MHP45L handling robot easily moves 100-pound workpieces without interfering with peripheral equipment in a booth, streamlining automated paint line layouts by eliminating the need for dedicated part transfer.
Posted: November 23, 2020
Workpieces in a painting area are often transferred by a dedicated transfer machine or a painting robot with an explosion-proof function. Because these robots aren’t optimized for transfer, there are payload limitations.
The 6-axis MHP45L from Motoman Robotics Division of Yaskawa America Inc. (Dayton, OH) resolves these restrictions. Capable of being mounted on the floor, wall, ceiling, or a shelf, the explosion-proof handling robot is Factory Mutual (FM)-approved for Class 1, Division 1 use in hazardous environments. Featuring a 99-pound (45 kg) payload as well as the high moment and inertia ratings required for large workpieces such as automotive bodies and components, the robot makes it possible to design compact, safe, and flexible painting lines.
The robot’s DX200-FM controller, which uses an easy-to-use touchscreen teach pendant, is also FM-approved for use in hazardous environments. The controller is available with a Category 3 Performance Level d (PLd) Functional Safety Unit (FSU) that supports safety-rated speed control, safety-rated soft axis and space limiting, and safety-rated monitor stop. In addition to facilitating safe operation in smaller and narrower work envelops with adjacent manual operations, these safety functions save costs and reduce floorspace requirements.
Standard networks like EtherNet, EtherNet IP, CC-Link, and DeviceNet are supported to enable connection to production line controllers.
Cables and air lines are routed through the robot base to upper arm to increase cable life, enhance safety, and reduce teaching time.
Horizontal reach: 9.4 feet (2,850 mm). Vertical reach: 16.7 feet (5,095 mm). Repeatability: ±0.07 mm.
