  • Patent number: 11685104
    Abstract: A dynamic correction system of a manufacturing process using wire is provided. The dynamic correction system includes a driving device, a path sensor, and a controller. The driving device is configured to: drive a carrier with a motion parameter and encapsulate the carrier with a wire. The path sensor is configured to obtain an actual path information of the wire encapsulating the carrier. The controller is configured to: obtain an actual path of the wire encapsulating the carrier according to the actual path information; obtain an actual path difference between a target path and the actual path; determine whether the actual path difference is greater than a predetermined error; and, when the actual path difference is greater than the predetermined error, control the driving device to change the motion parameter to cause the actual path of the wire encapsulating the carrier to approach the target path.

  • Patent number: 10540779
    Abstract: A posture positioning system for machine and the method thereof are provided. The system mainly consists of at least a depth camera mount on a robot to scan points of cloud of the machine, and a processing unit to apply an algorithm with the points of cloud and a contour vector file of the machine to obtain a transfer relationship. The processing unit further obtains a spatial relationship by a matrix calculation with the transfer relationship and a position relationship which exists between the robot and the depth camera. A route generating module of the processing unit generates, if needed, a moving route for the robot according to the spatial relationship.

  • Publication number: 20060123434
    Abstract: A disc discriminating device disposed in a disc changer is provided. The disc changer includes at least a tray having a recess. The disc discriminating device includes a sensing circuit and a conductor. The sensing circuit has a first contact and a second contact. The sensing circuit accordingly outputs a signal when the first and second contacts are electrically connected. The conductor has a first end electrically connected to the first contact, a protrusion penetrating an aperture disposed on a sidewall of the recess and protruding to the recess, and a second end interspaced by an interval with the second contact. The protrusion outside the recess is squeezed by a disc when loading into the recess, so that the second end of the conductor is electrically connected to the second contact. The sensing circuit outputs a signal according to the above conduction.
