  • Patent number: 11285713
    Abstract: A screen printing apparatus includes a squeegee driver that lifts/lowers a first lifting/lowering shaft and a second lifting/lowering shaft; a link mechanism including a swinging member that pivots about a horizontal axis by lifting/lowering operations of the first lifting/lowering shaft and the second lifting/lowering shaft; a squeegee unit installed to the swinging member; and a controller that controls at least a height of the squeegee unit and an orientation of the squeegee unit in a rotating direction by controlling the squeegee driver.
    Type: Grant
    Filed: April 10, 2019
    Date of Patent: March 29, 2022

  • Patent number: 10000056
    Abstract: A screen printing apparatus includes a pair of clampers that clamp a substrate, a mask plate contacted to the substrate, a pair of squeegees provided above the mask plate vertically, and a squeegee controller that selectively controls one of the pair of squeegees to move in the horizontal direction in abutment against the mask plate so that the selected one of the pair of squeegees slides on the mask plate.

  • Patent number: 9796035
    Abstract: A screen printing machine for forming a print of paste supplied to a mask plate having pattern holes, includes: a flexible filling squeegee which performs a squeegeeing operation in which the filling squeegee is moved relative to the mask plate in a printing direction; and a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction and to be movable together with the filling squeegee in the printing direction, and which scraps off the paste remaining on the mask plate after passage of the filling squeegee. In the squeegeeing operation, the filling squeegee is pushed up and bent by the paste to provide a clearance between a bottom end of the filling squeegee and the mask plate with the paste interposed therebetween so that the pattern holes are filled with paste with a prescribed filling pressure.

  • Patent number: 9409248
    Abstract: A screen printer includes a mask, a substrate holding unit that clamps and holds a substrate below the mask by clamping members, a substrate holding unit moving mechanism that moves the substrate holding unit to contact the substrate with a lower surface of the mask, a paste filling unit that fills pattern holes of the mask with a paste, mask suction portions provided in the clamping members which suck the mask contacted with the substrate. The mask suction portions keep sucking the mask when the substrate holding unit moving mechanism moves the substrate in a direction away from the mask to perform plate releasing, and release the suction of the mask in a state in which the mask sucked to the mask suction portions maintains a posture parallel to the substrate after the movement of the substrate is started.

  • Patent number: 9352409
    Abstract: A screen printing machine for forming a print of paste supplied to a mask plate having pattern holes, includes: a filling squeegee which is held to have a given clearance with respect to the mask plate, and which fills the pattern holes with the paste by moving the filling squeegee relative to the mask plate in a printing direction; and an urging member which urges the filling squeegee toward the mask plate such that at least the given clearance is maintained. The screen printing machine further includes a scraping squeegee which is held to maintain a given interval from the filling squeegee in the printing direction, and which scraps off paste remaining on the mask plate after passage of the filling squeegee by moving the scraping squeegee together with the filling squeegee in the printing direction.
