  • Publication number: 20130017040
    Abstract: In recent years, frames have gotten larger in size and thinner, and warping of the frames has posed a problem. If a warp of a frame is large, there is a high possibility that fetching the frame may fail. If fetching the frame fails, that is, if the frame cannot be fetched, the lead time of mounting gets longer. Further, the frame that cannot be fetched has to be manually removed by an operator. Therefore, a man-hour increases. According to the present invention, before a loader feeder fetches a frame from a frame magazine, a loader lifter is moved in a Y direction. Thereafter, the loader feeder fetches the frame from the frame magazine.

  • Patent number: 8336195
    Abstract: The invention is directed to an unfailing pickup operation of an electronic component from a component storage portion at a seam of storage tapes connected even using a connection tape and prevention of reduction in a pickup rate of an electronic component. A CPU sends a feeding command to a component feeding unit to perform a component feeding operation or the like. Then, when the CPU judges that a connection tape reaches a pickup position, the CPU drives an X axis drive motor and a Y axis drive motor to move a board recognition camera to the pickup position of the feeding unit, the camera takes an image of a storage portion of a storage tape, and a recognition processing device performs recognition processing. A correction value based on a result of this recognition processing is stored in a RAM, and a suction nozzle is moved taking this correction value into account and lowers to pick up an electronic component.

    Abstract: RFID tags are attached to tools of a preform head, a bonding head, and a push-up unit, and information related to each tool such as a dimension of a processing-target die is stored into the RFID tags. When a tool is mounted, an operator inputs manufacturing conditions related to the tool. On the other hand, when the information related to the tool read from the RFID tag by an RFID reader/writer and the manufacturing conditions related to the tool do not match each other, a message about wrong mounting of the tool is displayed on a monitor. Further, an operation history of the tool is written into the RFID tag by the RFID reader/writer when the production is completed. The operation history is read when the next production is started, and if the values of the operation history exceed predetermined numbers of times, a message is displayed on the monitor.
