Patent number: 11396057Abstract: A twin laser camera unitary assembly for a robot processing tool is disclosed. The assembly has a housing having a front wall defining an upright U-shaped channel into which a tubular portion of the tool is laterally insertable. A mounting support attaches the housing relative to the tool in operative position. Twin laser range finders are respectively mounted in the housing on opposite sides of the U-shaped channel in a symmetrical in-line arrangement with respect to the tool. A controller mounted in the housing is configured to receive robot control signals, operate laser projectors and process image signals produced by imagers of the laser range finders so that joint and bead position and geometry signals are produced in a robot reference frame. The assembly is designed and protected for use in industrial processes such as robotic laser and arc welding and sealant dispensing.Type: GrantFiled: July 2, 2019Date of Patent: July 26, 2022Assignee: SERVO-ROBOT INC.Inventors: Jean-Paul Boillot, Jacques-André Gaboury, Raynald Simoneau

Patent number: 10107913Abstract: A range finder device for monitoring a 3D position of a robot processing tool relative to a tracking device mounted adjacent to the robot processing tool is disclosed. A body attachable to the tracking device supports a laser unit and a camera unit. The laser unit projects a triangulation laser mark on a target area of the processing tool. The mark, a tool center point and a processing area are in a field of view of the camera unit. A control unit controls operation of the laser unit and has an image analyzer circuit for receiving an image signal produced by the camera unit, producing triangulation laser measurement data from the triangulation laser mark in the image signal, generating a signal indicative of the position of the robot processing tool as function of the triangulation laser measurement data, and transmitting the image signal produced by the camera unit.Type: GrantFiled: February 8, 2016Date of Patent: October 23, 2018Assignee: Servo-Robot, Inc.Inventors: Jean-Paul Boillot, Jacques-André Gaboury, Andrei Rusnac

Patent number: 10043283Abstract: A process tracking laser camera with non-eye-safe and eye-safe operating modes is disclosed. The camera has an image sensor with a field of view covering a target area of a workpiece. The camera also has first and second laser units for projecting respectively non-eye-safe and eye-safe laser beams towards the target area. A control unit has laser drivers for driving the laser units, a cut-off circuit operatively connected to the laser driver of the first laser unit for disabling its operation depending on a control signal, and a control circuit for controlling the laser drivers depending on a cut-off condition of the cut-off circuit controlled by a switch device so that the first laser unit is enabled and the second laser unit is disabled in the non-eye-safe operating mode while the first laser unit is disabled and the second laser unit is enabled in the eye-safe operating mode.Type: GrantFiled: May 31, 2016Date of Patent: August 7, 2018Assignee: Servo-Robot, Inc.Inventors: Jean-Paul Boillot, Éric Bureau, Jacques-André Gaboury

Patent number: 7557326Abstract: There are provided a laser joining head assembly and a laser joining method for simultaneously performing joint tracking and seam inspection of a joint while said joining head assembly is in relative motion along the joint. The laser joining head assembly comprises integrated tracking laser line projecting means and integrated inspection laser line projecting means for respectively projecting a tracking laser line and an inspection laser line on the joint, thereby allowing to respectively generate successive joint transverse profiles and seam transverse profiles. These profiles are processed to respectively provide joint data and seam data, thereby allowing to perform said joint tracking and said seam inspection of said joint during said motion.Type: GrantFiled: April 1, 2005Date of Patent: July 7, 2009Assignee: Servo-Robot Inc.Inventors: Jean-Paul Boillot, Adrian Bucur, Jacques-André Gaboury, Jean-Claude Fontaine

Patent number: 6730926Abstract: A sensing head for providing bi-dimensional and tri-dimensional data determinative of a position and an orientation of a target object is provided. The sensing head combines both a bi-dimensional and a tri-dimensional sensors. General illumination is associated to the bi-dimensional sensor to allow the acquisition of bi-dimensional data representative of the target object. A stripe-shaped laser light output is projected and diffused on the target object and is sensed by the tri-dimensional sensor. Tri-dimensional data is thus acquired. By proper processing of the bi-dimensional and tri-dimensional data, the position and orientation of the target object may be determined without moving the sensor head and without knowing its position and orientation.Type: GrantFiled: September 5, 2001Date of Patent: May 4, 2004Assignee: Servo-Robot Inc.Inventors: Jean-Paul Boillot, Raymond Boridy, Jacques-André Gaboury
