Method for manufacturing holographic mother board by using laser welding imposition

Abstract

The invention relates to a method for manufacturing a holographic mother board by using a laser welding imposition, which comprises the following steps: arranging nickel boards of unit holographs according to the requirements, and welding each unit holograph by using the laser energy to manufacture a holographic mother board which has a large dimension and comprises a plurality of unit holographs. The invention has the advantages that the method can be used for splicing unit holographs of arbitrary dimensions and is particularly suitable for splicing unit holographs of large dimensions; the laser welding has the characteristics of fine, smooth and flat welding joints, small thermal deformation and the like and can realize digitally-controlled automatic operation, thus the splicing speed is quick, and the splicing precision is high; and the holographic mother board formed by welding can be electroformed and reproduced into a plurality of mother boards, and the large board formed by laser welding can be also directly arranged on a moulding press for use.

Description

technical field [0001] The invention belongs to the field of holographic technology, in particular to a method for manufacturing a holographic master plate by laser welding imposition. Background technique [0002] At present, the technologies used for imposition at home and abroad can basically be divided into two categories: [0003] The first is a mechanical imposition machine for small-sized unit holograms, which uses the principle of hot stamping to splice small-sized unit holograms into a large-sized hologram master by hot stamping transfer. Due to the limitations of its principle and technology, at present, only small-sized holograms can be spliced, and the unit size is mostly within the range of 10 cm × 10 cm, and large-sized unit holograms cannot be spliced. [0004] The second is the silica gel imposition method. In principle, this method can splice large-sized unit holograms. It uses silica gel to replicate the unit holographic graphics that need to be spliced, ...

AI Technical Summary

Problems solved by technology

However, due to the softness of the silica gel, it is difficult to control the cutting and splicing accuracy, and the imposition cycle is also very long (because the silica gel replication of each unit holographic pattern generally takes 24 hours), the process is complicated, and human factors have a greater influence

[0005] Therefore, for large-scale unit holograms, there is currently no ideal imposition method and machinery to splice holographic masters with large-size unit holograms.
