Embodiment Construction

[0028] figure 1 The rolling process on the surface of the metal substrate 1 is schematically shown. The surface is configured as an open structure. In order to form the open structure, individual depressions 12 are rolled on the undeformed surface 11 of the metal substrate 1 which still has a smooth appearance. Arranged on the surface of the rolling bodies 22 of the roller 2 used are spherical caps 21 which penetrate the surface of the metal base plate 1 . For example, the spherical caps 21 are of the same size so that they produce the same negative structure on the substrate surface. As an alternative, however, the structural dimensions of the roller surface can be very different, and other shapes, for example conical or cylindrical, are also conceivable. In any case, this is the fine structure comprising the almost smooth undeformed raw background of the initial surface formed by rolling from the substrate surface.

Abstract

The invention relates to an electro-optical or electromechanical structural component, in particular, an LED, connector or stamped grid, or sliding element, made of a rolled metal substrate of a metal strip, or a sheet produced therefrom, made of Cu or a Cu alloy strip, Al or an Al alloy strip, Fe or a Fe alloy strip, Ti or a Ti alloy strip, Ni or a Ni alloy strip or a stainless steel strip, which has a specially structured surface. The structure of the surface allows joining using optical methods, even in the case of highly reflective surface coatings, and simultaneously improves the functional properties of the components used.

Description

technical field [0001] The invention relates to an optoelectronic or electromechanical component or sliding element according to the preamble of claim 1 . Background technique [0002] Known from the aluminum industry and the steel industry is the possibility of structuring surfaces by rolling processes, building aluminum and steel sheets for use as body parts, so that during the subsequent stretching process, it is not visible on the painted body to flowline. Examples of methods of directly structuring the surface of a work roll or belt are laser texturing, grinding and sandblasting. The so-called EBT method (Electron Beam Texturing) or the EDT method (Electron Discharge Texturing) is also known as a method for the production of textured surfaces. However, this type of rolled build results in rough surfaces with irregular geometries that cannot meet the optical or mechanical performance requirements for many applications.
