    摘要: A positioning method of a spot welding robot, the spot welding robot having a movable electrode tip and an opposition electrode tip opposed to the movable electrode tip. The method sandwiches a work piece to be welded between the pair of electrode tips and includes driving the movable electrode tip towards the opposition electrode tip with a servo motor and stopping the movement upon contact based upon a prescribed current value. The method further includes measuring an open separation of two opposing tips between the movable electrode tip and the opposition electrode tip and moving the opposition electrode tip towards the moveable electrode tip based upon the preset value and the open separation of the two opposing tips.

    摘要: An optical functional sheet characterized in that, at least within the sheet, a light diffusing phase and a transparent phase each extend along a direction perpendicular to the surface of the sheet and are alternately arranged along the sheet surface direction. The optical functional sheet has a smooth surface that can be surface-treated or laminated with another functional sheet and is provided with a light collecting effect due to the internal arrangements thereof that is capable of collecting both light diverging transversely and light diverging longitudinally using a single sheet. Thus, the sheet can be useful for applications such as the backlight for liquid crystal displays.

    摘要: A laser oscillator capable of executing a high-speed feedback control by reducing the control load of a main processor in the feedback control of the laser output. The laser is excited by an excitation source activated by one or more power supplies. The laser radiation is detected by a power sensor or a photodiode. A detected signal is A/D converted and fed to a sub processor or a high-speed DSP. The sub processor compares the current laser output value to a desired control value and calculates a deviation value in a predetermined period. The sub processor outputs a feedback signal to each of the power supplies according to a command from the main processor. Each power supply adjusts the supplied current to control the laser output. The main processor monitors conditions of the power supplies and controls a coolant circulation device. A factor regarding a load on a sequential control process, which may delay the feedback control, is eliminated and an analog circuit is unnecessary. The period time of the feedback control may be within 200 μs.

    摘要: A work mounting device in which an operation for teaching a robot to mount a work on a work mounting member is automated. The work is gripped by a hand placed on an arm tip portion of the robot and the operation for mounting the work on the work mounting member is taught. A plurality of distance sensors are disposed on the work mounting member or the hand. Distances between each sensor and the work or distances between each sensor and the work mounting member are measured. A robot controller maintains an attitude of the robot so that the distances detected by the distance sensors are uniform and, at the same time, allows the work to approach the work mounting member so that a plurality of holes of the work are engaged with a plurality of respective protrusions of the work mounting member. Based on the distance data detected by the distance sensors, a disturbance estimation observer, a load torque on motors for each axis or the like, the movement of the robot is stopped automatically when the work reaches a position where the work is in contact with the work mounting member or is very close to contact therewith. The position and attitude of the robot at this time is taught.

    摘要: A welding voltage value Vf and a welding current value IF are respectively monitored by a detector during execution of arc welding in accordance with a robot operation program, indexes are calculated which show how far the monitored values Vf and If are deviated from a command welding voltage value Vc and a command welding current value Ic specified in the operation program, and it is decided that there is a possibility of occurrence of a defective weld in arc welding under execution, when the calculated index exceeds a preset threshold value. Then, the data for arc-welding execution conditions and execution results are cumulatively stored in a defective weld history data area provided in a memory in accordance with the line number and the statement of the line in the operation program for each line constituting the program, and the cumulatively-stored data is displayed on a screen.

    摘要: A method of inducing arc generation in arc welding between a head of a wire and a workpiece, such that a robot supports a welding torch, thereby causing the head of the wire to be brought near a welding start position on a workpiece. However, if there is a failure to generate an arc between the head of the wire at the position and the workpiece within a predetermined time, at least one cycle is repeated of a sequential retrial motion, in which first the robot is made to move to cause the head of the wire to be moved at a predetermined speed from a position close to the present welding start position to another position away from the position by a predetermined distance, and then the robot is made to move in the opposite direction to cause the head of the wire to be moved at a predetermined speed toward the welding start position. Then, when an arc generation signal is detected during repeated performance of the retrial motion, the retrial motion is stopped, and a predetermined welding for the workpiece is started.
