Description

Secondary printing screen

This creation relates to a secondary printing screen, in particular to a secondary printing screen having a good aspect ratio of the printed pattern.

Screen printing is a technology for printing patterns onto printed materials through screen printing, which can be mass-produced and can reduce the cost of production. Therefore, the technology of screen printing has been widely used in electronic products.

With the advancement of technology and the improvement of living standards, the accuracy of electronic circuits in electronic products is also more demanding. Therefore, the quality of screen printing and the accuracy requirements of alignment systems are also quite strict. However, when it is necessary to print a thin line width and a thicker pattern, the conventional screen can not achieve the required requirements with only one printing, so for a pattern requiring a good aspect ratio, it is generally adopted. Secondary printing to achieve the required fine line width and high graphic thickness. However, the conventional printing equipment cannot directly dry the printing paste due to the current drying method, so different printing must be used in the process. The machine is used for printing, and in the case where the same printing machine cannot be used, the alignment error of the screen position is generated, so that the printing patterns cannot be accurately overlapped. Therefore, it takes a lot of time to replace the printing machine. Quasi-screen printing position, but this method can not absolutely match the position of the screen at the time of the first printing, which not only takes time to match, but also seriously affects the quality of the product.

For the above reasons, the purpose of this creation is to provide a secondary printing screen, especially A secondary printing screen for a printed pattern having a good aspect ratio.

To achieve the foregoing objectives, the present invention provides a secondary printing screen comprising: a frame, a first printing plate, and a second printing plate. The first printing plate is composed of a mesh fixed in a frame, wherein the first printing plate has a squeegeing surface and a first bonding surface; and the second printing plate has a second printing a plurality of pattern openings of the plate, and the second printing plate has a printing surface and a second bonding surface, wherein the second bonding surface is adhered to the first bonding surface; wherein the mesh in the first printing plate has a Printing ink. The printing ink is set in the first printing plate through the first printing, and the ink is added in the second printing, and the user adds the ink added in the second printing together with the printing ink set in advance through the doctor blade. And scraping on the printed matter, due to the secondary printing screen made of two printing plates, the thickness of the screen will be larger than the conventional screen, and the second printing version without the netting can avoid the printing disconnection. And the problem of incomplete pattern, so the pattern printed by the creation can obtain higher thickness and better fine line width than the conventional screen.

According to an embodiment of the present invention, the mesh is interwoven by a plurality of metal mesh wires, and the mesh is combined with an emulsion layer.

According to an embodiment of the present invention, the mesh is interwoven by a plurality of metal mesh wires, and the mesh is combined with a polymer layer.

According to an embodiment of the present invention, the second printing plate is a monolithic emulsion layer.

According to an embodiment of the present creation, the second printing plate is a monolithic sheet metal.

The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.

1 and 2 are divided into a top view and a side cross-sectional view showing a secondary printing screen according to a preferred embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the secondary printing screen of the present invention comprises: a frame 10, a first printing plate 20 and a second printing plate 30.

As shown in FIG. 1 and FIG. 2, the first printing plate 20 is formed by fixing a mesh cloth 22 in a frame 10. After the mesh cloth 22 of the first printing plate 20 is fixed, the second printing plate is used. The conventional plate-making step of coating, exposing, developing, and the like is performed such that the second printing plate 30 has a plurality of pattern openings 32 penetrating through the second printing plate 30. After the second printing plate 30 is completed, the second printing plate 30 will have a printing surface 31 and a second bonding surface 33, and the conventional coating and exposure of the first printing plate 20 is performed on the second bonding surface 33. The first bonding surface 24 of the first printing plate 20 is bonded to the second bonding surface 33, wherein the other end of the first bonding surface 24 has a squeegeing surface 23; 22 is interlaced by a plurality of metal mesh wires and combined with an emulsion layer having an opening 25 in the center of the first printing plate 20, the opening 25 being slightly larger than the pattern opening 32 of the second printing plate 30.

3A and 3B are divided into schematic diagrams showing the use of a secondary printing screen according to a preferred embodiment of the present invention. As shown in FIG. 3A, the user applies the printing surface 31 of the secondary printing screen to the printed matter 50, and performs the first printing by the printing machine, and adds the printing ink 60 to the printing surface 23, and transmits the same. The same angle and pressure push the blade 40 toward the wire end. At this time, the printing ink 60 will fill the hollow portion in the mesh cloth 22, so that the printing cloth 60 is provided in the mesh cloth 22 of the first printing plate 20. And the printing ink 60 is filled by the pressure of the doctor blade 40 to fill the first printing plate 20 without passing through the second printing plate 30.

As shown in FIG. 3B, after the first printing is completed, the user can directly perform the second printing without replacing the screen, and the user adds the ink 61 to the squeegee surface 23, and the squeegee is sprayed through different angles and pressures. 40 is pushed in the direction of the thread, and the printing ink 60 at this time is pressed by the ink 61 to pass through the plurality of pattern openings 32 penetrating the second printing plate 20 to form a pattern on the substrate 50.

In the secondary printing screen provided by the present invention, the mesh 22 is interlaced by a plurality of metal mesh wires and combined with an emulsion layer or a polymer layer, and the polymer material may be PET, PE, PI, PVC. One of PP, PTFE, PMMA, and PS is a composition having one of the polymer materials added thereto, however, the material combined with the metal mesh is not limited thereto. In the present embodiment, the mesh 22 is made of a metal material, but the material of the mesh is not limited thereto, and may be a metal, a Tedron, a polymer material, or an elastic nylon. In the present embodiment, the second printing plate 30 is a one-piece emulsion layer having a plurality of through pattern openings 32, but the manufacturer may also modify the material of the second printing plate 30 to change the second printing plate to have A plurality of metal sheets that extend through the pattern opening 32.

The secondary printing screen provided by the creation, through the printing ink set in the first printing plate and the second printing plate without the netting, so that the ink does not become uniform due to being stuck on the mesh or the mesh. In the case of ink transmission and disconnection, the thickness of the secondary printing screen combined by the two printing plates can print a higher thickness and a higher aspect ratio than the conventional screen, and there is no need to replace the screen. Or the printing machine avoids the problem that the printing pattern cannot be accurately overlapped due to the alignment error of the screen, and also saves the time spent replacing the machine and the alignment position, improves the product quality, and achieves creation. The purpose.

It can be seen from the above embodiments that the secondary printing screen provided by the present invention has industrial use value, but the above description is only a description of the preferred embodiment of the present invention, and those skilled in the art can Other improvements are described, but these changes are still within the spirit of this creation and the scope of patents defined below.
