Title: Laser beam processing robot
Inventor: MUNAKATA TADASHI
IPC: B23K26/21
Filed: 1990-08-16
Abstract: PURPOSE:To execute uniform welding by having a means for storing an operation start point and end point on the outer side of the beginning end and final end of a weld line, a control means which operates a robot body in accordance with this position and a means for starting the irradiation of a laser beam at the beginning point of the weld line and stopping the irradiation at the end point. CONSTITUTION:The positions of the beginning end and final end of the weld line and a processing speed are taught and are stored in the robot controller 2. The positions of the operation start point and end point which are previously determined by extrapolation and interpolation of the weld line by as much as the stroke necessary for accelerating and decelerating the laser beam processing robot from the positions of the beginning end and final end and the processing speed as well as the previously stored acceleration and deceleration parameters necessary for calculating the acceleration and deceleration strokes are first formed within a robot controller at the time of reproduction. The operation of the laser beam processing robot body is then controlled by using the positions of the operation start point and the end point. The weld line is welded by controlling an oscillator in such a manner that the laser beam is oscillated only when the tip of a nozzle torch exists in-between. The uniform welding is executed in this way and since only the beginning end and final end are taught, the teaching is easy.

Filed: 1989-08-22
Abstract: PURPOSE:To prevent output lines from being oscillated by preparing an output control means, and when both of a chip selection signal and a write command signal are active, fixing all data at the high level or the low level. CONSTITUTION:The memory element is constituted of a memory element body 20, data input terminals, data output terminals, and the output control means 30.
