A recently granted patent (Publication Number: US11688589B2) describes a carrier designed to hold multiple substrates in a vertical orientation while passing through a coater that applies a coating to the front face of each substrate. The carrier consists of a frame with an aperture, a bottom tap bar, a top tap bar, vertical support bars, and fasteners. The vertical support bars are positioned behind the back faces of the substrates and have multiple attachment positions for the fasteners, allowing substrates of different widths to be vertically stacked on top of each other in the aperture.

The carrier's fasteners can be pins or pegs, and the vertical support bars have slots, holes, grooves, or other openings for attaching the fasteners. The dimensions of the aperture can vary, with a horizontal dimension between 50 and 200 inches and a vertical dimension between 50 and 150 inches. The vertical support bars can be made of metal and may have a rail, channel, or groove design.

The substrates that can be held by the carrier include glass or plastic, and they can be windows intended for coating with an electrochromic device. The frame of the carrier is also made of metal, and the bottom and top tap bars may be made of a material that expands and contracts to match the thermal expansion and contraction of the substrates.

Additional features of the carrier include a pivot peg attached to the top tap bar, a transport mechanism for moving the carrier through the coater, and a shield to protect the frame during coating.

This patented carrier offers a solution for efficiently coating multiple substrates in a vertical orientation. Its design allows for the stacking of substrates with different widths, providing flexibility in the coating process. The use of fasteners, such as pins or pegs, and the attachment positions on the vertical support bars ensure secure and stable positioning of the substrates. The carrier's dimensions and materials are adaptable to accommodate various substrate sizes and thermal conditions. Overall, this carrier design has the potential to enhance the efficiency and effectiveness of coating processes for glass or plastic substrates, particularly in applications such as electrochromic window coatings.
