  • Publication number: 20210268603
    Abstract: A laser processing apparatus 3 includes: a laser head H; a head driving mechanism that moves the laser head H above a workpiece W; and a dust collecting box 60 that moves below the workpiece W and follows the laser head H. A non-contact support unit 7 is provided at an opening 61 of the dust collecting box 60, and the non-contact support unit 7 suctions a lower surface of the workpiece W toward a suction surface 71 and supports the workpiece W without bringing the lower surface of the workpiece W and the suction surface 71 into contact with each other. An outer support roller 81 and an inner support roller 82 that are each rotatable about an axis parallel to a width direction orthogonal or substantially orthogonal to a conveying direction Fy are provided at the opening 61.

  • Patent number: 10794685
    Abstract: An optical measurement system calculates a distance between an optical system and a measurement object based on reflected light beams corresponding to cores, compares a value indicating the distance with a threshold value for each of the reflected light beams, calculates an average value of all the values indicating the distance when the values in the reflected light beams corresponding to all the cores are equal to or greater than the threshold value or the values are less than the threshold value, and calculates an average value of the values indicating the distance which are equal to or greater than the threshold value or an average value of the values indicating the distance which are less than the threshold values when the values corresponding to some cores are equal to or greater than the threshold value and the values corresponding to the other cores are less than the threshold value.
