The present invention discloses a silicon wafer printer for double half-cell printing, comprising a work platform, a turntable assembly, a front-end conveyor, a left calibration module, and a right calibration module. A calibration vision camera is mounted above the front-end conveyor's end. The left linear module connects to a left motor module and then a left suction module. The right linear module connects to a right motor module, two calibration cylinders, calibration bearings, and a right suction module. It uses visual positioning to determine double half-cells' position/angle, adjusts the right half-cell with the left as reference, shortens alignment time, adopts single-head front-to-back printing and a smaller indexing disc, boosting turntable printing efficiency.

A degassing chamber for degassing a material located on a workpiece, comprises a vacuum source and a vacuum reservoir in fluid communication with the vacuum source, a secondary chamber, a port valve which is movable between an open position to allow passage of a workpiece therethrough between the exterior of the degassing chamber and the secondary chamber and a closed position in which the port valve is fluidly sealed, and a reservoir valve which is movable between an open position to provide fluid communication between the secondary chamber and the vacuum reservoir and a closed position in which the reservoir valve is fluidly sealed. The degassing chamber may be provided subsequent to a printing machine in a production line, and has particular application for degassing silicone material when producing fuel cells.
