  • Patent number: 12051613
    Abstract: A method of using a processing apparatus that includes a holding unit with a rotatable chuck table for holding a workpiece; a processing unit for processing the workpiece; a camera for imaging the workpiece that is movable in an indexing feed direction; and a control unit for controlling the components. The method includes forming a linear processed mark in the workpiece, and then moving the chuck table to an imaging zone, where the camera images the processed mark. The method further includes calculating correction values or a correction angle, and carrying out processing feed of the chuck table in the imaging zone under a condition in which the camera has been corrected in position in the Y-axis direction based on the correction values or the chuck table has been rotated by the correction angle.

  • Patent number: 11745374
    Abstract: A cutting apparatus includes a holding table that has at at least a part of a holding surface a transparent section including a transparent member and that holds a workpiece, a cutting unit including a cutting blade that cuts the workpiece held by the holding table, and a cutting water nozzle that supplies cutting water during cutting of the workpiece by the cutting blade, an imaging camera that images the workpiece through the transparent section, and a removing unit that removes a liquid adhered to the transparent section. The removing unit includes a contact member positioned at a contact position for making contact with the transparent section and a retracted position, and an X-axis moving unit that relatively moves on the transparent section the contact member making contact with the transparent section.

  • Patent number: 11699606
    Abstract: A cutting apparatus includes a table including a support plate transparent in a visible region, a cutting unit, a first feeding mechanism that includes a first moving section for supporting the table and a first motor, a second feeding mechanism that includes a second moving section for supporting the cutting unit and a second motor, a first camera disposed on the side of a first surface of the support plate, a second camera disposed on the side of a second surface opposite to the first surface of the support plate, and a storage section that stores positional deviation amounts in the X-axis direction and the Y-axis direction between an imaging region at a reference position of the first camera and an imaging region at a reference position of the second camera.

  • Publication number: 20210210375
    Abstract: A processing apparatus includes a processing feed unit and a control unit. The processing feed unit moves a holding unit along guide rails between a processing zone, and an imaging zone in which a workpiece is imaged by a camera. The control unit includes a correction amount calculation section configured such that, after forming a cut groove in the workpiece, the cut groove is imaged by the camera, and correction values in a Y-axis direction or a correction angle for the chuck table are or is then calculated from Y-coordinates of two points apart from each other in a processing feed direction on the cut groove, whereby when carrying out processing feed of the chuck table in the imaging zone, the camera is corrected in position in the Y-direction based on the correction values or the chuck table is rotated by the correction angle.
