Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] An embodiment of the metal mask manufacturing method of the present invention includes the following steps: (1) processing a convex-concave structure on the upper surface of the metal mesh frame; (2) filling the hollow space in the metal mesh frame with fillers, And make the upper surface of the filler flush with the upper surface of the metal mesh frame, and the metal mesh frame and the filler are combined to form a combination frame; (3) Clean the combination frame, remove the oil stain on the surface of the combination frame, and obtain a clean combination frame, The specific process is as follows: using cleaning equipment, under the condition of 25 ℃, spray the surface of the frame with degreasing liquid to remove the oil stains, and then wash and dry the process to obtain a clean combination frame; (4) conduct electricity to the fi...

Abstract

The invention discloses a metal mask manufacturing method and a metal screen frame. The metal mask manufacturing method comprises the following steps of: step (1), processing a convex-concave structure on the upper surface of the metal screen frame; step (2), filling a hollow part of the metal screen frame with a filler, and combining the metal screen frame and the filler to form a combined frame;step (3), cleaning the combined frame; step (4), carrying out electric conduction treatment on the filler; step (5), coating the combined frame; step (6), carrying out exposure reaction on a part where an opening is required, of the coated combined frame; step (7), developing by using developing equipment, and exposing the metal screen frame and the filler on an unexposed part; step (8), electroplating the upper surface of the combined frame, wherein a plating layer gradually grows to a place of the combined frame, which is not covered by printing ink, and forming a metal mask on the electroplating layer; and step (9), removing the coating, to be specific, putting the electroplated combined product in coating removal equipment for coating removal, and dissolving the printing ink and the filler completely by coating removal liquid medicine in the coating removal equipment to form the metal mask finished product.

Description

technical field [0001] The invention relates to a method for manufacturing a metal mask and a metal screen frame, belonging to the technical field of metal masks. Background technique [0002] The metal mask plate includes a metal mask (FMM, CMM) and a metal screen frame connected together. In the prior art, a laser welding method is used to weld the metal mask on the upper surface of the metal screen frame. A schematic diagram of this welding process is shown in figure 1 As shown, the net is first stretched on the metal frame, and the metal mask is stretched on the net machine after the pattern is made, and then laser welding is performed. [0003] This welding method has the following disadvantages: (1) The requirements for the metal mesh frame are very high, and the welding surface of the metal mesh frame is required to be smooth and flat without concave and convex points, otherwise there will be false welding or raised welding points. (2) Since the metal screen frame i...
