Abstract
A printing device capable of improving the printing accuracy by preventing positional displacement of a stencil applies paste on a stencil onto a substrate by spreading the paste by sliding a squeegee along a surface of the stencil disposed on the substrate. Outer attracting means for holding the stencil by attracting an undersurface side thereof is provided on the outside of a squeegee sliding region in which the squeegee slides over the stencil.
Claims3
A printing device that applies paste on a stencil onto a substrate by spreading the paste by sliding a squeegee along a surface of the stencil disposed on the substrate, comprising:
- a pair of conveyors for conveying the substrate in a transport direction;
- a stencil holding member, disposed above the paired conveyors, for holding the stencil in a state that the stencil is stretched over the substrate;
- and
- an attracting block, disposed on the outside of the paired conveyors, and on the outside of a squeegee sliding region in which the squeeze slides along the stencil, wherein
- the attracting block is disposed beneath the stencil, and includes an outer attracting member, disposed on a top surface of the attracting block for holding the stencil by sucking an undersurface of the stencil disposed on the substrate to attract the undersurface of the stencil onto the top surface of the attracting block,
- the paired conveyors are constituted of a fixed conveyor, and a movable conveyor which is movable in a direction orthogonal to the transport direction of the substrate with respect to the fixed conveyor to thereby change an interval of the paired conveyors in accordance with a size of the substrate, and
- the attracting block is fixedly mounted on the movable conveyor to thereby displace together with the movable conveyor which is moved for the interval of the paired conveyors.
