Problems solved by technology

However, there are still two problems in this method. First, because the metal sub-plates are relatively thin, and because the joints are all a very thin straight line, the strength of the electroforming is not high, and it is easy to break in the later imprinting application; Second, when splicing sub-boards and sub-boards, human eyes need to observe the alignment, which not only reduces efficiency, but also lowers precision

Embodiment Construction

[0023] Please refer to figure 1 , figure 1 It is a flow chart of making a metal mother plate according to the first embodiment of the present invention. As shown in the figure, the first is step S11: splicing the pre-fabricated metal sub-boards according to the layout pattern of the mother board to be made. The splicing action is best carried out on a flat table, because for metal sub-boards, the thickness is often only a few tens of microns, and the thickness difference between different metal sub-boards is also less than 10um, so for splicing flat Degree requirements are very high.

[0024] Then step S12: After the splicing is completed, with the texture facing upward, use adhesive tape to fit and fix the seams on the texture surface, so that the metal sub-plates are not easy to separate, and a large-sized metal mother board with gaps is formed. The tape used is preferably acid-resistant, alkali-resistant, and high-temperature-resistant tape to avoid corrosion by the elec...

Abstract

The invention relates to a method for making a metal mother board. The metal mother board is made by splicing at least two metal daughter boards together, and each metal daughter board has lines of a laser image. In the method, an abutted seam between the at least two metal daughter boards is stuffed mainly in an electroforming manner, wherein a concave-convex structure is arranged on the abuttededge of each metal daughter board, and the concave-convex structures of adjacent daughter boards are matched with each other. By adopting the concave-convex structures, the electroforming strength among metal daughter boards is increased, simple and accurate counterpoint is also realized, and the quality of the finished product of the metal mother board is improved.

Description

technical field [0001] The invention relates to a method for manufacturing a metal mother board, in particular to a method for manufacturing a metal mother board using an electroforming pattern. Background technique [0002] Laser light-variable images are used as anti-counterfeiting marks due to their difficulty in production and high barriers to entry, and are widely used in packaging, certificates, stamps, coins, etc. A high-efficiency laser optical variable image production method is to transfer a texture pattern with a specific shape from a metal mother board to a product to be imprinted by embossing. Therefore, making metal mother boards becomes the key to this technical method. [0003] With the development of the market, people have higher and higher requirements for the laser pattern on the metal mother board, and it is often necessary to design a laser pattern with various visual effects on a metal mother board. Laser patterns with different visual effects have d...
