Embodiment 1

[0050] In a typical implementation of the present invention, an imprinting device capable of imprinting special-shaped curved surfaces includes a plurality of microelement platens 100 arranged in several rows and columns, and two adjacent microelements The pressure plates 100 are set at a set distance, or when the micro-element pressure plates are set at the same height, two adjacent micro-element pressure plates are set in contact; and each micro-element pressure plate is connected to the driving mechanism, or all the micro-element pressure plates are connected to the drive mechanism through elastic parts. Institutional connections.

[0051] Among them, the size of the micro-element platen is selected for the object to be imprinted. For example, for a larger workpiece such as the wing plate of an aircraft, the size of the micro-element platen is relatively enlarged, which can be 3-5mm; the number of micro-element platens is preferably 30 -200, or even more, is more suitable f...

Embodiment 2

[0067] The differences between this embodiment and Embodiment 1 are:

[0068] The driving mechanism includes a magnet and an electromagnetic driver on the top of the box. The micro-element pressure plate is fixedly connected with the magnet, and the magnet is connected to the telescopic rod. The electromagnetic driver corresponds to the magnet one by one. The cross-sectional area of ​​the magnet is the same as that of the micro-element pressure plate. , the electromagnetic force generated by the electromagnetic field drives the micro-element platen to press on the mold and forms micro-nano structures on the surface of the material.

[0069] It should be noted that the telescopic rod can be a multi-joint telescopic rod, the top of the telescopic rod is fixed by the box, and the box plays a role in limiting the moving direction of the telescopic rod.

[0070] In this embodiment, the micro-element pressing plate is cylindrical and has a higher height, so that the magnet 190 is in...

Embodiment 3

[0073] The difference between this embodiment and embodiment one is:

[0074] The push-pull plate is partly transparent and partly opaque, and then through the push-pull plate, the temporary suspension of the UV lamp irradiation when the sample is switched (the opaque part is aligned with the UV lamp), without repeatedly switching the UV lamp.

[0075] For example, the ultraviolet lamp is set on the inner side of the box, the width of the push-pull plate is smaller than the width of the box, the inside of the push-pull plate is opaque, and the outside is transparent. Under normal conditions, the transparent part of the push-pull plate is located above the ultraviolet lamp. When it is necessary to pause, Move the push-pull plate to the inside of the box to cover the UV lamp.

Abstract

The invention discloses impressing equipment capable of achieving impressing of a special-shaped curved surface and a using method thereof, solves the problem that impressing equipment in the prior art can only achieve plane impressing, and has the beneficial effects that the application range is wide, and impressing of a complex curved surface can be achieved.According to the specific scheme, the impressing equipment capable of achieving impressing of the special-shaped curved surface comprises a plurality of infinitesimal pressing plates, the infinitesimal pressing plates are arranged in a plurality of rows and a plurality of columns, and every two adjacent infinitesimal pressing plates are arranged at a set interval or can be arranged in a contact mode. Each infinitesimal pressing plate is connected with the driving mechanism, or all the infinitesimal pressing plates are connected with the driving mechanism through elastic pieces.

Description

technical field [0001] The invention relates to the technical field of embossing, in particular to an embossing device capable of embossing special-shaped curved surfaces and a method for using it. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The process of changing the thickness of the sheet under the action of the mold and embossing the undulating pattern or characters on the surface of the part is called embossing. However, the current embossing technology is mainly aimed at flat imprinting, which cannot emboss complex curved surfaces, let alone process flat and curved surfaces at the same time, and the working range is limited. [0004] In the UV imprint process, the monomer-coated substrate and transparent stamp are loaded into the aligner and held on their respective chucks under vacuum. When the optical alignment of the substra...
