Screen Printing Adapter Device
A screen printing adapter device is disclosed. In an example, the screen printing adapter device includes a body configured as an accessory to a printing board having a tag printing surface. The body is attached to a screen and moves on and off of the printing board along with the screen for a screen printing operation. The body supports areas of the screen for a squeegee that are otherwise unsupported by the printing board. The example screen printing adapter device also includes a shoulder edge of the body shaped to fit adjacent and conform to a shoulder edge of the printing board. The example screen printing adapter device includes a collar edge of the body. In an example, the collar edge of the body is shaped to fit fully around a perimeter of the tag printing surface of the printing board.
SCREEN PRINTING APPARATUS AND SCREEN PRINTING METHOD
A screen printing apparatus moves a mask, inserted through an insertion opening, to a printing position at which paste is printed onto a substrate via a mask moving mechanism, and includes: a first detecting unit that detects one of a front frame component and a back frame component of the mask at a first detection position on a path along which the mask inserted through the insertion opening is moved to the printing position; a second detecting unit that detects one of the front frame component and the back frame component at a second detection position closer to the printing position than the first detecting position is; and a print suspension controller that suspends printing when the second detecting unit detects one of the front frame component and the back frame component while the first detecting unit is detecting one of the front frame component and the back frame component.
COMBINED PRINTING PRESS
There is described a combined printing press (10) for the production of security documents, in particular banknotes, comprising a screen printing group (3) and a numbering group (4) adapted to process printed substrates in the form of individual sheets or successive portions of a continuous web. The screen printing group (3) is located upstream of the numbering group (4) and comprises at least one screen printing unit (32-33) designed to print a pattern of optically-variable ink, which optically-variable ink contains flakes that can be oriented by means of a magnetic field. The screen printing group further comprises a magnetic unit (36) located downstream of the screen printing unit (32-33), which magnetic unit (36) is designed to magnetically induce an optically-variable effect in the pattern of optically-variable ink applied by the screen printing unit (32-33) prior to drying/curing of the optically-variable ink. The screen printing group (3) further comprises at least one drying/curing unit (37) designed to dry/cure the pattern of optically-variable ink in which the optically-variable effect has been induced by the magnetic unit (36), prior to transfer of the printed substrates to the numbering group (4).

MULTI-OPERATION TOOL FOR PHOTOVOLTAIC CELL PROCESSING
Multi-operation tools for photovoltaic cell processing are described. In an example, a multi-operation tool includes a conveyor system to move a photovoltaic (PV) cell continuously along a conveyor path through a laser scribing station and an adhesive printing station. Furthermore, the PV cell may be aligned to a laser head of the laser scribing station and a printer head of the adhesive printing station in a single alignment operation prior to being laser scribed and printed with an adhesive in a continuous process.
Solder paste bead recovery system and method
A stencil printer is configured to print an assembly material on an electronic substrate. The stencil printer includes a frame, a stencil coupled to the frame, a support assembly coupled to the frame, and a print head gantry coupled to the frame. The print head gantry includes an elongate beam that rides along rails provided on the frame and a print head assembly supported by the print head gantry in such a manner that the print head assembly is configured to traverse the stencil during print strokes. The print head assembly includes a print head having a squeegee blade assembly configured to roll solder paste along the stencil. The stencil printer further includes a solder paste bead recovery system configured to remove a bead of solder paste from a top surface of the stencil and to deposit the bead of solder paste onto a new replacement stencil.
Screen printing device and method for screen printing onto substrates
The application relates to a printing device for printing onto substrates, in particular solar cells, wafers or printed circuit boards, including a squeegee means and including at least one printing table, wherein the squeegee means is arranged above the printing table, and including at least one conveying means, by means of which a substrate can be transported away in each case to a printing nest below the squeegee direction and away out of the printing nest after the printing process has taken place. It is provided that the printing table has several conveying means, which are arranged side by side and aligned parallel to one another and which each have at least one printing nest, and that the squeegee means has at least one squeegee, which can be moved over each printing nest in order to print successively onto the substrates, which are arranged in the printing nests.
Method for replacing items in a stencil printer using a dual function tooling tray
A dual function tooling tray for a stencil printer includes a perimeter frame, a first frame member spaced from a first side of the perimeter frame, a second frame member spaced from a second side of the perimeter frame, and a third frame member extending between and secured to the first frame member and the second frame member. The third frame member is configured to support at least one squeegee blade assembly.
