摘要:
A screen printing apparatus comprises a print executing part 20, a substrate loading part En, a substrate unloading part Ex, transferring and holding means, said transferring and holding means transferring a substrate W, which has been loaded from the substrate loading part En at a substrate standby position P1, to a print executing position P2 and holding the substrate, and a substrate recognition camera 50 for imaging the substrate. The transferring and holding means includes a clamp unit 14 and its drive mechanism, and is configured to transfer the substrate W to the print executing position P2 upon holding the substrate W with the clamp unit 14 in a state of enabling printing thereon by the print executing part 20 at the substrate standby position P1 in advance. The substrate recognition camera 50 is provided to be capable of imaging the substrate W, which is held by the clamp unit 14 and transferred from the substrate standby position P1 to the print executing position P2, in course of the transfer of the substrate W.

Rotary machine for the silk-screen printing of flat sheets (10a) comprising a rotating printing screen (200), a fixed doctor blade (300) arranged inside it, a conveyor belt (600) endlessly mounted on a pair of rollers, one of which is a drive roller (1600), for supplying flat sheets (10) to the printing screen (200) and an actuating motor (20,20a), there being provided devices (205,1600,605,1000,30) for controlling and adjusting the feed speed of the conveyor belt (600) so as to synchronise feeding of the flat sheet (10,Ov) to be printed, fed by means the said conveyor belt, with rotation of the printing screen (200,Or).
摘要:
A screen type printer has a conveying unit (40) and a printing table (54). The conveying unit (40) conveys a sheet from a first position to a second position through a printing region of the table (54). The sheet is supplied from the first position, printed at the printing region and discharged from the second position. A frame (42) having a gripper (43) is movable between the first position and the printing table (54). The gripper (43) holds a front edge of the sheet when the frame (42) moves from the first position to the table (54), and releases the sheet when the frame reaches the table (54).
摘要:
To provide an improved temperature control device in an inner space of a screen printer. A temperature control device 20 is disposed in the inner space of a printer covered with a cover 24. A heating/cooling unit 100 thereof is disposed by being fixed to a printer main body 10 behind a mask holding device 16 within an upper section of the inner space. Four heating/cooling units 100 which heat and cool air by using a Peltier device assembly are disposed side by side in a width direction of the printer. A heat exchanger and a fan on a temperature control side are surrounded by a common housing 132. The air whose temperature is controlled inside the housing 132 is supplied to a blower 220 disposed adjacent to a mask 46 by using a hose 224, and is caused to blow to a squeegee moving region so as to control the temperature. Heat is radiated and absorbed by the heat exchanger and the fan on a side opposite to the temperature control side of the Peltier device assembly. Furthermore, a fan 190 promotes exhausting of air, thereby efficiently controlling the temperature.
摘要:
A screen-printing method, including the steps of filling, in a state in which a screen (20) having through-holes (86, 88) is contacted with a print surface (12) of a substrate (14), the through-holes with a print material, and thereby applying the print material (330) to the print surface of the substrate, moving, after the filling step, one of the screen and the substrate relative to the other of the screen and the substrate, in one or more cycles, on a plane parallel to the print surface of the substrate, in one or more directions parallel to one or more straight lines, and separating, after the moving step, the screen and the substrate from each other.
摘要:
A shock absorber pad (110) for absorbing shock caused by separation of a perforated sheet mask from a surface on which a pattern of a screened medium has been formed by forcing a viscous material through the mask which includes a plurality of protuberant features (111) which have a separation (G) determined in accordance with a nominal viscosity of the screened medium and a transverse feature dimension (P) based on characteristic stand-off spacing or mask feature size increases pattern quality and extends mask life. Hollow pattern features also improve pattern quality by reducing pad contact area with the mask during separation while allowing the pad features to span mask features. Methodology of shock absorber pad design and adjustment of screened medium viscosity to pad feature spacing are included.
