  • Patent number: 8839834
    Abstract: A masking device capable of effectively carrying out a masking operation using a masking jig by means of a robot. A step S5, wherein the masking jig is taken out by a second robot, must be completed prior to step S6, and may be carried out until step S2 has been completed, otherwise, may be carried out concurrently with step S4. Since the taking out operation of the masking jig by the second robot may be concurrently with the detecting/taking-out operation of the workpiece or the applying operation of adhesive by the first robot, cycle time may be reduced.

  • Patent number: 7149602
    Abstract: Provided is a correction data checking system, for robots, which makes it easy to reveal the cause of a machining defect. A laser machining head and a distance sensor or a sensor for detecting a work line are attached to the distal end of a robot arm. A robot is driven based on a teaching program, and a copying control technique is implemented based on information sent from the sensor so that the distance between the laser machining head and a workpiece will be equal to a set value. A path of taught positions of the laser machining head and a path of actual positions thereof are displayed in comparison with each other on a display of a teaching console or the like. Moreover, the difference between the taught position and actual position is calculated and displayed.

  • Patent number: 7038165
    Abstract: If a machining program is reproduced in a robot controller and a robot is moved on a machining route, then a detection signal of a distance sensor is fetched through a distance sensor amplifier, and tracer control is carried out so as to keep a distance between a laser machining head and a workpiece at a predetermined value. In an acceleration and decoration processing in a corner, a restriction means that restricts a maximum acceleration and a maximum jerk is used to control an acceleration and a jerk of the robot not to exceed respective predetermined values, and prevents generation of a vibration when the laser machining head passes through the corner.

  • Publication number: 20050143861
    Abstract: A processing system for stably processing a workpiece even if the shape of the workpiece changes every production lot of the workpiece, or by a change of the workpiece. The distance between the workpiece and an end of a nozzle of a laser machining head is measured by a distance sensor. A data correcting value ?Z?mn is calculated using a measured distance ?Zrn at each teaching point and a set gap value ?Zs (step S6-S15). By using ?Z?mn, the data of the teaching points are corrected to new data of the teaching points of the program (step S16-S19). The distance between the workpiece and the end of the nozzle of the laser machining head does not become larger because the teaching points of the processing program are corrected every time when the workpiece is processed. The interference between the workpiece and the head may be prevented and the processing may be stably implemented because the amount of correction becomes smaller when the position of the head is corrected during the processing.

  • Publication number: 20050055134
    Abstract: A device for determining an interference region of a robot, capable of determining an interference region/non-interference region and the like on an off-line layout space without difficulty. Geometric data of a robot and peripheral objects is read from a CAD system or the like to be displayed in the form of a layout display, to thereby form a cage region. An initial occupied region is found by calculating a three-dimensional position of each arm at an initial position. An operation simulation is run, and the tree-dimensional positions are repeatedly calculated, thereby finding the aggregate sum of the occupied region. After the robot is moved, a total occupied region G, an overlapping region H, a protruding region K, a non-occupied region M and the like are displayed in different colors, to thereby perform layout correction of a peripheral object, a change of the cage region, etc.

  • Publication number: 20050011867
    Abstract: When a laser beam is irradiated from a laser welding torch onto a surface of a welding target workpiece, a plasma is generated. This plasma is introduced to an optical fiber, extracted by a filter-added half-silvered mirror, branched by half-silvered mirrors and a reflecting mirror, split by a bandpass filter, and detected by an optical sensor. Using a detection result of the optical sensor, a control for keeping the intensity or the temperature of a plasma beam constant is exercised.

  • Patent number: 6763284
    Abstract: An image of a reference object is captured using a camera and displayed. A measurement starting point is pointed by an image position pointing device. A corresponding view line is obtained using a position on the image and a position and a direction of the camera, a robot approaches to the reference object such that it does not deviate from a projecting direction to move to a position suitable for measurement. A light is projected on the reference object and measurement of an inclination of a face of the object in the vicinity of a measuring point is started. An image including a bright line image on the reference object is photographed and 3-dimensional positions of points sequentially measured along a working line. A movement path of a robot is created using these positions as teaching points for a working robot.

  • Patent number: 6680461
    Abstract: A nozzle system for laser machining capable of maintaining an interference region of a robot in a teaching operation to be substantially the same as that in a laser machining operation. An optical fiber supporting unit is attached to a nozzle body unit having laser beam converging lens for performing a laser machining operation. An optical fiber for supplying a laser beam is connected to an optical fiber connector on the optical fiber supporting unit. A laser machining is performed by combination of the nozzle body unit and the optical fiber supporting member attached to a distal end of a robot arm. In a teaching operation, a camera supporting unit (dummy nozzle) having substantially the same dimension as the nozzle body unit and supporting a camera at a predetermined position is used in place of the optical fiber supporting unit and the nozzle body unit.

  • Patent number: 6555784
    Abstract: A laser machining apparatus with a simplified laser beam transmitting network. Respective laser beams form laser generators LS#11 to LS#25 divided into groups of G1 and G2 are aggregated to fiber-optic cables H1 and H2 by confluence devices HC1 and HC2 and transmitted to a most upstream laser beam outlet OP1. The laser beams are further aggregated to a fiber-optic cable H3 and distributed to a branch fiber-optic cable HH1 by the laser beam outlet OP1, and then distributed by laser beam outlet OP2 to OP8 to branch fiber-optic cables HH2 to HH8. The laser beams distributed to branch fiber-optic cables are focused by the machining tools TL1 to TL8 attached to robots RB1 to RB8 for laser machining. By controlling output levels of the laser generators with different oscillation wavelengths and different polarization characteristics, blend ratio of the laser beams can be adjusted. Distribution ratios of the laser beams at the laser beam outlets OP1 to OP8 are adjustable.
