Laser-Based Seam Finder Improves Weld Quality, Reduces Cycle Times

Description

AccuFast II uses a non-contact, commercial point laser instead of "touch" sensing, which allows the robot to quickly and accurately locate welding seams.

 

Built for the arc welding robot line, the AccuFast II uses a non-contact, commercial point laser instead of "touch" sensing, which allows the robot to quickly and accurately locate welding seams. The system can greatly reduce cycle times by removing the need to cut the weld wire, and provides faster search speeds by eliminating wire deflection.

 

The AccuFast II laser seam finder is compact, mounted in-line with the welding torch and is compatible with Yaskawa Motoman's industry-leading thru-arm torch design robots. The sensor uses the same input and output signals as traditional touch sense, allowing it to be easily retrofitted into existing robot installations.

 

Macro job routines simplify programming by providing a single instruction in the robot job for detecting a seam or feature. The laser sensor is housed in an enclosure with a pneumatic shutter to protect it from the harsh welding environment. An optional laser target aids in maintaining the sensor TCP and can adjust points if the sensor is serviced.
