Description

Printing template with metal foil support mesh

The present invention relates to a printing stencil having a metal foil support mesh, and belongs to the technical field of screen printing stencils, and more particularly to a printing stencil having a metal foil formed on the surface of the support mesh.

Referring to Fig. 1, it is a conventional printing stencil having a metal foil composed of a frame, a support mesh, a metal foil layer, an elastic film layer and the like. The conventional printing template is a combination of a support net disposed in the outer frame, and the metal foil layer is joined on one side of the support mesh, and is further disposed on a side of the metal foil layer that is not in contact with the support mesh. The elastic film layer; when the printing stencil is used for printing, the printing material is poured into one side of the printing stencil without a metal foil layer, and the elastic film is laminated on the printed matter, by a doctor blade or the like The workpiece of the printed material is extruded such that the printed material is printed onto the printed matter through the layer structure.

Although it is known that a printing stencil having a metal foil can achieve an improvement in printing precision and an improvement in printing quality, and at the same time, it can extend the life of the printing stencil. However, since the conventional printing stencil is joined to the support layer by the electroforming method, if the casting process is not processed, the mold release is likely to occur, and the cause of the print quality deterioration is formed. Therefore, the creator of this creation proposes a printing template with improved metal foil. In order to reduce the various factors that may affect the printing accuracy, and to create a printing template to improve the production yield.

The purpose of the present invention is to provide a printing stencil having an improved metal foil in order to solve the problems described in the prior art.

After more precise development of the creator of the creation, a printing stencil with improved metal foil is proposed, and the technical problem to be solved is achieved by the following technical means: a printing stencil with metal foil, including: a frame; a metal foil supporting net, the metal foil is bonded to the support net, and the surface of the supporting net is formed into a conductor to form the metal foil supporting net; an elastic film is flatly attached to the surface of the metal foil supporting net, the elastic film has At least one opening of a predetermined pattern.

The processing process utilized by the metal foil support mesh may be a sputtering process, a coating process, or an evaporation process. The surface of the support net is coated with a metal conductor by the foregoing process to form the metal foil support net, which can omit the process of casting the support net to the metal foil layer in the prior art, thereby not only saving a process, but also It is possible to avoid the occurrence of problems such as poor printing accuracy caused by demolding in the prior art.

In addition, the present invention has a printing stencil of metal foil, and the outer frame can be a metal casting frame; and the metal foil supporting mesh is directly adhered to the inner side of the outer frame, so that the printing stencil has greater strength when used, and is difficult to be used. Deformation.

Furthermore, the metal foil described above is coated on the surface of the support mesh by a sputtering process, a coating process or an evaporation process, and the metal foil may be a nickel alloy or a stainless steel. And the elastic film can be a high score Made of sub-materials.

It can be seen from the above technical means that the present invention can indeed improve the problems existing in the prior art, and provide a printing stencil of metal foil which saves process cost and improves the quality of the printing stencil.

The printing stencil with improved metal foil proposed in the present invention will be further described below in conjunction with the drawings.

First, in order to make the technical features of the present invention easy to read, the features of the prior art will be described again. Referring to Fig. 1, there is shown a perspective exploded view of a conventional printing stencil having a metal foil. As is apparent from the figure, the conventional printing stencil 1 is composed of a member such as an outer frame 11, a support net 12, a metal foil layer 13, and an elastic film layer 14. The combination of the printing stencil 1 is such that the support net 12 is disposed in the outer frame 11, and the metal foil layer 13 is cast on one side of the support net 12, and the metal foil layer 13 is not supported by the support. The elastic film layer 14 is disposed on one side of the contact of the net 12; the printing The stencil 1 not only achieves improved printing precision, but also has the advantages of extending the service life of the printing stencil.

However, since the conventional printing stencil 1 is joined to the layer of the metal foil layer 13 and the support web 12 by electroforming, if the casting process is not processed, the mold release is likely to occur, and the printing results in poor print quality. The cause of the change.

In order to improve the aforementioned problems, please refer to the drawings 2, 3A and 3B at the same time, the present invention proposes a printing stencil 2 with an improved metal foil, comprising: an outer frame 21, a metal foil support net 2 and an elastic Membrane 23.

A metal foil support web 22 is constructed by bonding a metal foil 221 to a support web 222 such that a surface of the support web 222 forms a conductor.

The elastic film 23 is flatly attached to the surface of the metal foil support net 22, and the elastic film 23 has at least one opening 231 of a predetermined pattern.

As shown in FIG. 3A, the textured structure of the metal foil support mesh 22 is woven by the angle between the contact angle of the outer frame 21 and the specific angle A and A+90 degrees; by this design, the metal foil support mesh 22 can increase the strength at the staggered network junction and is less prone to displacement during operation to maintain the accuracy of the through-hole of the printing area.

Referring to FIG. 3B again, the process of processing the metal foil support mesh 22 utilizes a sputtering process, a coating process, or an evaporation process to bond the metal foil to the support mesh 222. The foregoing process may also select to thicken or thicken the specific network line position of the support net 22, and the purpose of the thickening not only achieves control of the blanking amount and speed of the printing material, but also increases the support net. life.

The combination of the components of the printing stencil with metal foil is as shown in Fig. 4. A perspective view of a printing stencil having an improved metal foil. When the printing stencil 2 of the present invention is used for printing, the printing material is poured into one side of the printing stencil 2 which does not have the elastic film 23, and the elastic film 2 is pressed onto the printed matter, and can be squeezed by a doctor blade or the like. The workpiece of the printed material is printed on the printed matter through the layer structure.

By the above-mentioned improvement, the process of casting the support net 12 into the metal foil layer 13 by a conventional process can be omitted, and the process omitting not only saves a process, but also saves time and cost for the process, and can avoid Conventional mentions that problems such as poor printing accuracy caused by demolding occur.

In addition, the present invention has a metal foil printing stencil 2, and the outer frame 21 can be a metal cast frame; and the metal foil support net 22 is directly bonded to the inner side of the outer frame 21, so that the printing stencil 2 has The metal foil 221 disposed on the metal foil support mesh 22 may be a nickel alloy or stainless steel; and the elastic film 23 may be made of a polymer material, and as shown in FIG. 5 The elastic film 23 has a specific opening, and since the elastic film 23 can be surely attached to the surface of the metal foil support net 22, the printing accuracy can be greatly improved during the printing operation.

As stated above, this creation can indeed improve the problems of the prior art. The above-mentioned aspects are merely illustrative of the embodiments of the present invention, and are not intended to limit the present invention in any way, and without departing from the technical features of the present invention, any technical content using the above-mentioned connection is made. The equivalent of a simple transformation is within the scope of protection of the present invention.
