Abstract:
A stencil printer (10) includes a frame (12), a stencil coupled to the frame, and a print head (20) coupled to the frame to deposit and print viscous material over the stencil. The stencil printer further includes a lift table assembly (22) configured to support the substrate (16) in a transport position and a print position, and a conveyor system (14). The conveyor system includes a pair of rail members (28, 30) 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 (28, 30), a lift tool assembly (32) coupled to the rail member. The lift tool assembly (32) is configured to cooperate with the lift table assembly (22) and to engage and support the substrate (16) at a transport height and a print height.
Abstract:
A stencil printer (10) includes an electronic substrate support (22) configured to support an electronic substrate (24) and move the electronic substrate between a lowered position and a raised position. The stencil printer further includes a stencil shuttle assembly (18) configured to support a stencil (16) and to move the stencil between a first position in which the stencil is positioned toward a front of the stencil printer and a second position in which the stencil is positioned toward a back of the stencil printer. The stencil printer further includes a print head (20) configured to engage the stencil to dispense a material onto the substrate during a print stroke. The stencil printer further includes a drive assembly configured to move the print head (20) to perform the print stroke and configured to selectively move the stencil shuttle assembly (18) between the first and second positions.

Abstract:
The present invention(s) provide an apparatus and method for processing substrates (150) in a screen printing chamber (102) that can deliver a repeatable and accurate screen printed pattern on one or more processed substrates. In one embodiment, the screen printing chamber is adapted to perform a screen printing process within a portion of a crystalline silicon solar cell production line in which a substrate is patterned with a desired material. In one embodiment, the screen printing chamber is a processing chamber positioned within the Rotary line tool or Softline™ tool available from Baccini S. p. A.
Abstract:
A feeding board for substrate treatment, equipped with support units (2) whereon a mounting board (3) is mounted that allows to treat substrates or objects placed on the mounting board (3) and to stow excess material underneath the mounting board if necessary. These feeding boards can be interconnected to allow continuous production processing.
Abstract:
A stencil printer for printing viscous material on a substrate includes a frame, a stencil coupled to the frame, and a print head, coupled for the frame, to deposit and print viscous material over the stencil. The stencil printer further includes a substrate support to support a substrate in a print position and a substrate clamping assembly to clamp the substrate in the print position. In a certain embodiment, the substrate clamping assembly includes a pair of rail members coupled to the frame. The rail members are adapted to engage opposite edges of the substrate. The substrate clamping assembly further includes a pair of foils, one for each rail member, with each foil being releasably secured to the rail member in a position so that the foil overlies the substrate. The substrate clamping assembly also includes a pair of clamping members, one for each rail member and foil, to releasably secure the foil in place on the rail member.
Abstract:
A vibratable support (2) for supporting a workpiece (44) in a screen printing apparatus, the support comprising: a mount (14) for mounting to a screen printing apparatus; and at least one transducer (12) disposed on the mount, the at least one transducer including a surface for supporting a workpiece and vibrating the same thereabove.
Abstract:
A device at printing machines for printing of multi-colour prints on printing substrates (23), in particular textiles. The device is of a kind comprising a number of treatment stations (15), such as printing and drying stations (16, 17) and a number of carriers for printing substrates (22). These are arranged to successively bring the printing substrates from station to station or vice versa, that the stations are brought to cooperate with the carriers for the printing substrates. Each carrier for the printing substrates (22) consists of a channel plate provided with a number of ventilation channels (27). The carrier for the printing substrates (22) is essentially internally ventilated over its whole working area. The carrier for the printing substrates (22) is produced of a material having good heat conducting properties, and at least parts of the walls surrounding (24, 25, 26) the ventilation channels (27) are designed with a low weight and thereby a low heat accumulating capacity.
