Makeup system special for manufacturing wide-surface laser holographic mother set

Abstract

The invention provides a makeup system special for manufacturing a wide-surface laser holographic mother set, which comprises an upper top steel platform and a lower top steel platform that are oppositely arranged up and down. The system further comprises a moving platform and a moving assembly. The moving platform comprises a single-column hydraulic machine body and a makeup assembly fixed to thelower end of the single-column hydraulic machine body. The single-column hydraulic machine main body is movably suspended above the lower top steel platform; the moving assembly is connected with thesingle-column hydraulic machine body and can drive the single-column hydraulic machine body to move along the X axis and the Y axis which are perpendicular to each other; the downward-jacking steel platform is used for fixing a makeup base material; and when the single-column hydraulic machine body is started, the makeup assembly can be driven to move downwards and press the makeup base material.The problem that relative errors are generated due to the fact that a base material and a makeup head of a common makeup machine move at the same time is solved, meanwhile, the surface temperature ofthe base material at the position is reduced, thermal deformation is reduced, and uniformity and stability of holographic image quality are facilitated.

Description

technical field [0001] The invention relates to the technical fields of ultra-fine processing and laser holography, in particular to an imposition system specially used for making wide-area laser holographic master plates. Background technique [0002] With the development of molded holographic technology, laser holographic printing technology is widely used in the anti-counterfeiting of tobacco, salt industry, pharmaceuticals and other industries, as well as the promotion and use of holographic packaging films in these industries. In order to improve production efficiency and the needs of wide-format materials, laser holographic printing technology The emergence of wide-format imposition technology in the holographic field. Imposition technology is to use the principle of thermal embossing transfer to transfer the unit holographic images of various ultra-fine grooves to the substrate, and then repeat the transfer multiple times according to the required size, and finally sp...

AI Technical Summary

Problems solved by technology

[0005] The pressure-providing four-column hydraulic press determines that the general imposition machine is open around. The imposition substrate a is directly exposed in the workshop, and the dust particles flowing in the air are easy to adhere to the imposition substrate a, which affects the image quality and reduces the finished product. Pass rate

[0006] The imposition substrate a is suspended and fixed on the frame e, and it is easy to cause expansion and deformation when heated. The holographic image is prone to position shift and uneven heating during imprinting. Especially when the unit holographic image is large, it is more likely to appear pressure and Uneven heating, leading to quality problems of uneven brightness of holographic images, resulting in waste products

[0007] When the ordinary wide-format imposition machine is working, the imposition head b2 must move left and right and up and down, and the imposition substrate a must also move back and forth along with the frame, which is prone to the problem that the position accuracy of the holographic image on the substrate a is not high. Will affect the product qualification rate
