Laser-Based Seam Finder Improves Weld Quality, Reduces Cycle Times
July 1, 2018
AccuFast II, an economical laser-based seam finder for Yaskawa Motoman's arc welding robot line, features improved sensor capabilities. "The improved sensor offers increased performance by providing more reliable and repeatable feedback to the robot controller regarding part position," said a company spokesperson. It also provides readings on a variety of materials and at angles of measurement that were not formerly possible.
AccuFast II utilizes a non-contact, commercial point laser instead of "touch" sensing with the weld wire, which allows the robot to quickly and accurately locate welding seams. It reduces cycle times not only by removing the need to cut the weld wire, but it also 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 through-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.
