Publication number: 20110180518Abstract: A resistance welding method, which resistance-welds a pair of workpieces by gripping the workpieces with a pair of electrode tips under a prescribed welding pressure, and supplies a welding current through the electrode tips to the workpieces, includes the steps of detecting a change in an amount of expansion of a nugget produced in the workpieces, along a direction in which the electrode tips grip the workpieces therebetween, determining whether the detected change is smaller than a threshold value or not, and gradually increasing the welding current flowing through the workpieces after the detected change is judged as being smaller than the threshold value.Type: ApplicationFiled: January 26, 2011Publication date: July 28, 2011Applicant: HONDA MOTOR CO., LTD.Inventors: Eisaku HASEGAWA, Yushi AOKI, Mitsugu KANEKO, Taku MAKITA, Katsumi TAKEISHI

Patent number: 7934408Abstract: In a roller hemming method for folding a flange erected from a workpiece by pressing a working roller against the flange and moving the working roller relative to the flange, the flange is folded by: a first temporary bending step of bending a tip-side portion of the flange into a state that the tip-side portion is inclined; a second temporary bending step of bending a remaining, base-side portion of the flange into a state that the base-side portion is inclined; and a full bending step of bending the thus-bent flange into a final shape so that the flange is into contact with a flange-proximate portion.Type: GrantFiled: October 5, 2007Date of Patent: May 3, 2011Assignee: Honda Motor Co., Ltd.Inventors: Eisaku Hasegawa, Hiroshi Miwa, Katsumi Takeishi, Takeshi Nakamura

Patent number: 7537378Abstract: A wire disconnection inspecting device includes a vehicle position recognition unit for detecting that a vehicle has reached an inspection position; a preparation timing recognition unit for detecting that a step preceding by one is reached; a terminal for transmitting an operation signal to an ECU so as to make an electrical connection to a heating conductor; an infrared camera for imaging a rear shield of the vehicle; and a main processing unit for acquiring thermal image data from the infrared camera and inspecting disconnection of the heating conductor. The main processing unit recognizes that the vehicle has reached a step preceding by one according to the preparation timing recognition unit and makes electrical connection to the heating conductor via the terminal. The main processing unit acquires the image data from the infrared camera when the vehicle has reached the inspection position.Type: GrantFiled: November 25, 2005Date of Patent: May 26, 2009Assignee: Honda Motor Co., LtdInventors: Keita Sekine, Kazuyuki Fukamachi, Katsumi Takeishi, John Cheek

Patent number: 5341458Abstract: In a method and system for generating teaching data for robots, a plurality of virtual target points are disposed in the vicinity of each of target points allowable on design, where a tool center point of a robot is to be positioned. The virtual target points and the original target point are combined into "target points taken in a broad sense". Each of the target points taken in the broad sense is given as a point which has been confirmed as a tool-attainable point on an off-line teaching apparatus. When a necessary correction is made on-line to teaching data generated by the off-line teaching apparatus, including as data the target points taken in the broad sense, an operator can select a suitable point from the target points taken in the broad sense and carry out a process of correcting the teaching data, regarding the suitable point as being a starting point.Type: GrantFiled: September 10, 1992Date of Patent: August 23, 1994Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masakatsu Kaneko, Hidetaka Nosse, Katsumi Takeishi
