  • Patent number: 10415962
    Abstract: A non-contact and optical measuring automation system, configured to electrically connect to a computer to measure the profile accuracy of a disk cam, includes a base, a rotating chuck, a moving stage module and a laser displacement meter. The rotating chuck is disposed for clamping the disk cam. The moving stage module includes a first linear motion stage movable relative to the base in a first direction and a second linear motion stage movable relative to the first linear motion stage in a second direction. The computer is able to control the rotation of the rotating chuck and the movement of the moving stage module, and is able to control a beam emitted from the laser displacement meter projecting onto a profile surface of the disk cam so as to obtain a profile deviation value of the disk cam by using the laser triangulation method.

  • Patent number: 10151585
    Abstract: A non-contact and optical measuring automation system includes a base, a rotating chuck to clamp a disk cam, a moving stage module and an optical measuring module. The moving stage module includes a first linear motion stage movably disposed on the base, a second linear motion stage movably disposed on the first linear motion stage, and a rotary motion stage rotatably disposed on the second linear motion stage. The optical measuring module disposed on the rotary motion stage includes a laser-emitting unit and an image-capturing unit. The laser-emitting unit projects a light beam onto a cam surface of the disk cam, and the image-capturing unit receives scattering light to capture a grayscale measuring image including a profile speckle pattern. A computer calculates a profile speckle characteristic value according to the grayscale measuring image and the surface roughness value according to the profile speckle characteristic value.

  • Patent number: 10095322
    Abstract: A mouse roller module includes a roller, a swinging arm, a movable block and an adjusting device. The roller includes a recess with a toothed surface. The swinging arm includes a contacting part, a linking part and an adjusting part. The contacting part is connected with a first elastic element. In response to an elastic force of the first elastic element, the contacting part provides a pressing force to the toothed surface. When the adjusting part is pushed by the movable block, the swinging arm performs a swinging motion. The movable block is pushed by the piston. While the position of the piston is adjusted by the adjusting device, the movable block is moved and the swinging arm performs the swinging motion. The pressing force of the contacting part provided to the toothed surface is adjusted in response to the swinging motion.
