A stencil printer includes a stencil, a material applicator to apply material on the stencil, and a stencil wiper assembly to selectively wipe the stencil. The stencil wiper assembly includes has a quick-change material module having a supply roller to receive a roll of material, a take-up roller to receive used material, a drive to move the material across the stencil from the supply roller to the take-up roller, and a controllable tension device configured to vary a tension of the material when driving the material from the supply roller to the take-up roller.

A circulating feeding printer combining screen printing and digital ink jetting, includes a rack. The rack includes an upper rack layer and a lower rack layer, and the two layers are respectively provided with a transmission platen capable of moving relative to the rack. Each transmission platen is provided with a movable printing platen bearing a print medium capable of sliding relative to the transmission platen, a locking device locking the movable printing platen, and the transmission platen is arranged between them. The platen transfer devices capable of transferring the movable printing platen onto the transmission platen at the different layer are disposed on the rack, separately located at two sides of the transmission platens. The rack is further provided with a screen printer and an inkjet printer used for printing separately.

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.

A printing device includes a printing section configured to execute a printing process of a viscous fluid on a printing target using a screen mask, and a receiving section configured to receive an accommodation rack having multiple shelf sections for accommodating frames configured to support exchangeable members for a printing process that is executed at the printing section.

A processing line for processing a substrate used for the manufacture of a solar cell is provided. The processing line includes a first station including a first chamber. The processing line includes a second station. The second station includes a second chamber and a printer in the second chamber. The processing line includes a linear guide extending at least from the first chamber to the second chamber. The processing line includes a robot arm. The processing line includes an actuator assembly to move the robot arm along the linear guide. The robot arm is movable along the linear guide to a position inside the first chamber. The robot arm is movable along the linear guide to a position inside the second chamber.

Accommodating rack 51 is used in a printing device including a printing section that performs a printing process of viscous fluid on a processing object using a screen mask, and accommodates, in a shelf shape, a replacement frame including a support portion that supports a replacement member used in the printing device and a frame-side stopper. The accommodating rack includes an accommodating section configured to accommodate the replacement frame, a guide section configured to support the replacement frame and guide the replacement frame between the accommodating section and an outside, and a rack-side stopper protruding toward an inside of the frame from a reference outer surface of the replacement frame and engaging with the frame-side stopper to restrict removal of the replacement frame in a pulled-out state in which the replacement frame is pulled out from the accommodating rack.
