  • Publication number: 20160316592
    Abstract: A tape feeder includes a gate, a gate drive mechanism, and a tape feed mechanism. The gate is provided in an insertion port through which a carrier tape storing components is inserted. In the gate drive mechanism, a tape feed mechanism which drives the gate in opening and closing directions feeds the components stored in the inserted carrier tape to a pickup position. The gate drive mechanism includes a spring member which biases the gate in the closing direction, and a solenoid which drives the gate in the opening direction against a biasing force of the spring member.

  • Publication number: 20150296669
    Abstract: A second tape conveying mechanism 20B includes a sprocket 21B allowed to rotate freely only in a first rotating direction corresponding to a tape conveying direction, and a first urging member 30 which urges and causes a carrier tape 14 to engage the sprocket 21B. When a preceding tape 14(1) engages the sprocket 21B and a subsequent tape 14(2) is inserted, the second tape conveying mechanism 20B abuts against a leading end of the subsequent tape 14(2) to prohibit entry of the subsequent tape 14(2). After the preceding tape 14(2) passes a tape stopper 35a, a position of the second tape conveying mechanism 20B is changed from a tape entry prohibition position to a tape entry permission position.

  • Publication number: 20150147143
    Abstract: There is provided a tape feeder that feeds a carrier tape to supply components to a component suction position for a mounting head in a component mounting apparatus. The tape feeder includes a first tape feed mechanism which is provided in a downstream side and feeds a preceding tape to the component suction position, and a second tape feed mechanism provided in an upstream side and feeds a following tape from a tape introducing port side toward the first tape feed mechanism.

  • Patent number: 5608815
    Abstract: An image testing device captures an image of a test object using a TV camera and raster-scans the image to search the test object for a scratch or spot. The device protects its test precision from being deteriorated by lowered brightness of an illuminator and properly maintains the illuminator by outputting an alarm on detecting a lowering of the illuminator. To realize the capabilities of the image testing device, it comprises a brightness measure circuit, a general determination circuit, etc. The brightness measure circuit receives a multivalued gray image signal or image data from the frame memory through a switching unit, obtains an average value of picture elements in a brightness measure area in a test object image, and outputs it as a measured brightness signal. The general determination circuit corrects, in proportion to a measured brightness a binarization threshold for use in detecting a picture element indicating a defect.
