Problems solved by technology
[0006] The manufacturing method of the above-mentioned vapor deposition cover is not only complicated in steps, but also easily causes deformation or displacement of the mesh of the vapor deposition net during the process of stretching the vapor deposition net by the fixtures, and it takes a lot of time to adjust the fixtures stretching strength
In addition, during the process of welding the vapor deposition mesh to the metal frame, the mesh holes of the vapor deposition mesh may also be deformed or displaced, so it takes a lot of work to perform a Totalpitch inspection after the welding is completed
It can be seen that this conventional AMOLED evaporation mask manufacturing method has always had the problems of poor manufacturing efficiency and low yield, which need to be solved urgently.

Embodiment Construction
[0040] figure 1 It is a flow chart of the manufacturing method of the metal shielding described in the present invention. In the present invention, the manufacturing method is used to manufacture an evaporation mask (FinePitchMetalMask, FMM) of an organic light-emitting diode, but it is not limited thereto. The manufacturing method can also be used to manufacture general metal shields, such as: Printing shields used in the manufacture of touch panels or printing shields used in IC packaging operations. The manufacturing method includes a metal frame feeding operation S1, a metal sheet feeding operation S2, a welding operation S3 and a laser drilling operation S4. Wherein, the metal frame feeding operation S1, the metal sheet feeding operation S2 and the welding operation S3 are carried out on a flat machine.
[0041] Such as figure 2 As shown, the stretching machine includes a workbench 7, a support device 71 and a welding device (not shown) that are located on the top su...

Abstract
The invention discloses a method for manufacturing a metal shield. The method includes sleeving a metal frame outside a support device of a working platform. Then, a metal thin board is disposed on a top face composed of the metal frame and the support device. Then the metal thin board is welded with the metal frame for forming a shield miniature. Finally, the laser drilling device is used for drilling on the shield miniature, so that a plurality of holes are formed in the metal thin board. Compared with the prior art, the metal thin board is disposed on the metal frame and welded with the metal frame first and then is drilled, so that a problem of deformation or shift of the holes of the metal shield can be avoided and then the yield of the metal shield is improved.
Description
technical field [0001] The invention relates to a method for manufacturing a metal shield and a laser opening device for manufacturing the metal shield, in particular to a method for manufacturing a shield and a laser opening device capable of improving yield. Background technique [0002] In the prior art, the manufacturing method of the active-matrix organic light-emitting diode (AMOLED) evaporation cover is to first form a plurality of tiny meshes on a metal sheet with a thickness of only about 40 μm by patterned etching. , to make an evaporation network. The size of each mesh hole on the evaporation net is only about 50 μm, and the distance between adjacent mesh holes is only about 70 μm. [0003] Another method for manufacturing the above-mentioned evaporation net, as shown in U.S. Patent Publication No. 2011 / 0183271, is to first form a plurality of (strip) holes on a thin metal plate, and then use a laser beam to open the holes in these holes. The walls are trimmed i...
