The present disclosure provides a mask device and a manufacturing method thereof, and an evaporation system. The mask device includes a frame, strip alignment plates and a strip support plate, hollow portions are provided in the strip alignment plates, and the strip alignment plates are fixed on the frame; the strip support plate and the strip alignment plates cross each other, a plurality of welding spots are provided on the surface of the strip support plate proximal to the frame, and are welded and fixed to the frame, and the plurality of welding spots are provided in the region of the strip support plate corresponding to the hollow portions.

Mask device and manufacturing method thereof, evaporation system

The present disclosure relates to a mask sheet. The mask sheet includes a plurality of mask units. Each mask unit includes an evaporation effective area and a plurality of welding areas that are distributed around the evaporation effective area according to a preset rule. The distribution of the welding areas around the evaporation effective areas of the mask units at the edge of the mask sheet is consistent with the distribution of the welding areas around the evaporation effective areas of the mask units located in the inner region of the mask sheet.

Mask sheet and method for manufacturing the same

The embodiments of the present disclosure propose a device for inspecting a mask plate, a method for inspecting a mask plate, and a corresponding method for controlling light sources. The device includes: an image sensor configured to capture an image of the mask plate; and a plurality of light sources disposed on one side of the mask plate opposite to the image sensor, wherein at least one of the plurality of light sources is configure to emit light when the image sensor is capturing an image of a first region of the mask plate, and the at least one light source comprises light sources within a first range, wherein the first range corresponds to the first region and an orthographic projection of the image sensor on a light source plane falls within the first range. The method for controlling light sources includes: turning on at least one of a plurality of light sources disposed on one side of the mask plate opposite to an image sensor, which corresponds to a first region of the mask plate to be inspected, when the image sensor is moved to a position corresponding to the first region.

Device for inspecting mask plate, method for inspecting mask plate, and corresponding method for controlling light sources

A jointing device for metal mask plate welding includes a jointing device body. A height of the jointing device body is smaller than a welding height of a welding gun. The jointing device body has a through-hole corresponding to a welding area of a metal mask. A width of the through-hole is larger than a welding spot diameter of the welding gun. The jointing device body is used for jointing the metal mask to a metal mask receiving frame.
