A conveyor system for a stencil printer includes a pair of rail members extending through a frame and configured to transport the substrate through the stencil printer. A lift tool assembly is configured to support the substrate at a transport height and a print height. The lift tool assembly includes a lifter portion configured to be engaged by a support of the lift table assembly. A foot of the lifter portion has at least two permanent magnets configured to secure the foot of the lifter portion to the support when engaging the support to the lifter portion, and at least one vacuum pocket formed in a bottom surface of the foot of the lifter portion. The vacuum pocket is configured to selectively secure the lifter portion in place on the support.

Lift tool assembly for stencil printer

A conveyor system for a stencil printer includes a pair of rail members, with the pair of rail members extending through a frame and configured to transport the substrate through the stencil printer. The conveyor system further includes, for each rail member, a lift tool assembly coupled to the rail member. The lift tool assembly includes a lifter portion, a main plate secured to the lifter portion, and a clamping member coupled to the main plate. The clamping member is configured to move horizontally between a substrate engaged position and a substrate disengaged position. The lift tool assembly further includes a thin foil coupled to the main plate. The thin foil is configured to move vertically and horizontally, independent from the clamping member.

Edge lock assembly for a stencil printer

A stencil printer includes a frame, a stencil coupled to the frame, and a print head coupled to the frame to deposit and print viscous material over the stencil. The stencil printer further includes a lift table assembly configured to support the substrate in a transport position and a print position, and a conveyor system. The conveyor system includes a pair of rail members coupled to the frame. The pair of rail members extends through the frame and is configured to transport the substrate through the stencil printer. The conveyor system further includes, for each rail member, a lift tool assembly coupled to the rail member. The lift tool assembly is configured to cooperate with the lift table assembly and to engage and support the substrate at a transport height and a print height.
