  • Patent number: 8649894
    Abstract: A method for controlling a board stopping position includes a calculation step for calculating an extended length of the electronic component mounted on the board and extended from the board end portion in the transfer direction by one of the electronic component mounting machines; and a correcting and stopping step for correcting a stopping timing of the conveyer belt to be stopped in response to the detection signal which is outputted from the board sensor and stopping the board at the mounting position, based on the calculated extended length of the electronic component in a subsequent stage electronic component mounting machine arranged subsequent to the one of the electronic component mounting machines.

  • Patent number: 8448834
    Abstract: A board printing system is provided with a printing apparatus for printing solder paste on each board, a printing inspection apparatus for inspecting a printed state of solder paste on each board, a transfer device for transferring each board in a forward direction from an unloading portion of the printing apparatus to a loading portion of the printing inspection apparatus, a reversible feed holding device configured to be able to hold a failure board which was taken out from the loading portion of the printing inspection apparatus as a result of being judged by the printing inspection apparatus to be rejected, after feeding the failure board in a reverse direction and then, to load the failure board to the loading portion of the printing inspection apparatus by feeding the failure board in the forward direction, and a selection device for enabling the transfer device and the reversible feed holding device to be used selectively.

  • Patent number: 6272984
    Abstract: A squeegee for use in screen printing, including a flexible portion, and one separation or two separations extending from a contact edge of the flexible portion for contact with a screen, toward a base portion of the squeegee, thereby at least partly separating the flexible portion, so that the flexible portion includes a first portion between the one separation and a lateral edge of the flexible portion, or between the two separations, and a second portion different from the first portion, and so that the first portion and the second portion are flexible independent of each other.
