  • Publication number: 20120325885
    Abstract: In the configuration where a cover tape separating mechanism 50 partially separating a cover tape 15e from a carrier tape 15 is provided in an upper member 32 of a guide section 30, a pressing member 43, which presses the carrier tape 15 from the cover tape 15e, is provided in the upper member 32 on the upstream side of the cover tape separating mechanism 50. Accordingly, it is possible to suppress the early separation of the cover tape 15e from the base tape 15a that does not yet reach the cover tape separating mechanism 50.

  • Patent number: 8327761
    Abstract: A screen printer capable of concurrently, efficiently subjecting a plurality of different types of substrates, to a printing operation. The screen printer makes up an electronic component mounting line and prints electronic component bonding paste on a substrate. A substrate conveyance section that conveys a substrate forwardly or backwardly in a direction of conveyance of a substrate is disposed at an intermediate position between a first screen printing section and a second screen printing section arranged symmetrically with respect to a center line CL. It thereby becomes possible to adopt a variety of substrate conveyance forms, as required, such as return conveyance for returning the substrate from a downstream machine to an upstream side of the screen printer and bypass conveyance for letting the substrate sent from an upstream side pass through the screen printer, to thus be conveyed to a downstream machine.

  • Publication number: 20120305585
    Abstract: In the separation of a cover tape 15e from a carrier tape 15 performed by a cover tape separating mechanism 50, a cover tape 15e, which is separated from a base tape 15a by a separating blade edge 51f, comes into contact with a concave conical surface 52c, so that one side portion of a cover tape 15e is bent toward the other side portion; and the bent cover tape 15e is pressed against a guide surface 32s from below while the carrier tape 15 is guided to a pick-up position. Accordingly, the cover tape 15e is folded on the base tape 15a in a flat shape.

  • Patent number: 7809461
    Abstract: In estimating a curved surface model by approximating the shape of the board surface of a circuit board, auxiliary measurement spots are set other than measurement spots on the board surface, eligibility as a sampling displacement magnitude in estimating a curved surface model is determined according to a difference in a displacement magnitude from a work reference surface. When the sampling displacement magnitude is determined to be ineligible, a new measurement spot is reset. By this operation, a local increase and decrease in the displacement magnitude due to a discontinuity of the board surface exerts no influence on the estimation of the curved surface model, and the curved surface model approximated more closely to the shape of the actual board surface is estimated, leading to an improvement in the work quality with the working height adjusted to the proper height.
