摘要:
Methods and apparatus to deliver ink to printing systems are disclosed. In one example, a disclosed apparatus (100) includes control valves (108a, 108b, 108c) which are coupled to a logic device (134). Together, the control valves and logic device control the flow of constituent components of press ready ink before the constituent components (102, 104, 106) are mixed into press ready ink and sent to a gravure impression cylinder ((132).
摘要:
The invention relates to a printing unit (4) with a first screen-printing cylinder (12) that, together with a second cylinder (17), defines a printing gap (14), said printing unit being characterized in that the second cylinder (17) is likewise a screen-printing cylinder.
摘要:
The invention relates to a device and to a method for applying a medium (12) in the form of liquid, powder or paste to a substrate (2), having a container (8) for the medium (12) and a transport device (1) which takes the medium (12) from the container (8) and discretely distributes it. In a propelling device the medium (12) is selectively transferred from the transport device to the substrate (2) with a propellant which is separate from the medium, or in the propelling device the medium is selectively removed from the transport device, and the remaining medium is transferred from the transport device to the substrate (2).
摘要:
A screen printing method for screen printing solder paste at a reference print speed by using a squeegee, the screen printing method comprising: a step for, upon an occurence of print standby time during a printing operation, measuring the print standby time; and a step for, at a resumption of printing with the print standby canceled, screen-printing the solder paste placed on a screen mask during the standby time, by moving the squeegee at an adjusted print speed lower than the reference print speed based on a relationship between the print standby time and a print time due to the adjusted print speed after the resumption of printing.
摘要:
A paste dispensing transfer system of a stencil printer is configured to print an assembly material on an electronic substrate. The transfer system includes a paste cartridge mechanism coupled to a print head assembly of the stencil printer, and a rotary indexing mechanism coupled to a frame of the stencil printer. The paste dispensing transfer system is configured to transfer a used paste cartridge from the print head assembly to the rotary indexing mechanism supported by the frame and to transfer a new paste cartridge from the rotary indexing mechanism to the print head assembly.

A method of performing a fully automated, single changeover process within a stencil printer includes identifying at least one item for replacement within the stencil printer, transporting an item to the stencil printer by a single change movable cart, removing a used item identified for replacement and delivering the used item to the movable cart, and installing a new item within the stencil printer from the movable cart. A system to perform a fully automated, single changeover process within a stencil printer includes a single change movable cart configured to transport an item to the stencil printer, remove a used item scheduled for replacement, and install the item within the stencil printer.
