Description

The invention relates to the field of identification of material resources and can be used for marking electrically conductive parts, for example, rolled products, vehicle parts, mechanical engineering, aircraft, nuclear products, in particular TVELs, and the defense industry, etc.

A known method of identification [1], based on the assignment of a material resource identification number. The way to create a tag is characterized in that a vibrating electrode is placed with a gap above the electrically conductive material resource and an electric spark discharge is created between them, the electrode being moved along and across the information grid according to the law of random numbers, the identification number and the visual picture from the electrodischarge process are scanned simultaneously and the subsequent one the identification process is carried out by comparing the identification number and the visual image from the electric discharge process.

However, this identification method is unreliable and inefficient due to the length of the process of applying identification features.

There is an electric-discharge method for manufacturing an irreproducible identification tag by applying an identification number, an information grid and an irreproducible picture to it by performing discharges and entering an irreproducible picture into a database [2], characterized in that the irreproducible picture is created by a discharge between the main and additional electrodes, and the identifiable a dielectric product, such as paper, is installed between the primary and secondary electrodes. However, this method is applicable only for creating identification marks on paper.

As a prototype, a method of manufacturing identification marks [3] on a metal by electrically discharging onto a medium, assigning it a digital code and a virtual information grid was chosen. An irreproducible picture is created by a discharge between a tag and a composite electrode made of nanocomposites of ultrafine metal powders, according to the law of random numbers, at least one spot is extracted from all the electric discharge spots, its (their) coordinates are entered into the database on the information grid, and these selected spots are removed spectral characteristic and enter it into the database, and identification is carried out in two stages.

However, this method has significant disadvantages, since it requires the use of expensive spectral instruments. The rejection of these devices, in principle, allows the scanner to take the characteristics of discharges on a metal carrier. The main disadvantage of this method can be recognized as low efficiency, the need for multiple spark discharges, which does not allow to raise the productivity of this process to the desired level. Pointwise spots from discharges by themselves, without spectral characteristics, have low information saturation. All these shortcomings arise due to the use of a spark discharge, which can create only limited spot sizes and cannot create more information areas with maximum identification saturation. All these shortcomings result from the use of a spark discharge, which can create only limited spot sizes and cannot create extended and evaporated bands with maximum identification saturation.

The objective of the invention is to repeatedly increase productivity and obtain through the use of the process of separation of films from each other identification marks with maximum identification saturation. The task can also include expanding the scope of application for both metal and dielectric products.

A method for creating an identification mark on a metal by using a metal film with a dielectric double-sided coating and applying a physical information mark with subsequent cutting into individual cells, applying a digital code and identification grid to individual cells is proposed.

A feature of the newly proposed method is that one of the films deposited on the adhesive to the metal film is mechanically separated from the metal film, the irreproducible matrices made of adhesive and metal formed during the separation process are provided with a digital code, an information grid, covered with a new layer of transparent adhesive film, scanned and how the identification tag is entered into the database.

The method of creating an identification mark on a metal film includes applying a physical information mark on it with an information grid and an individual digital code, using a metal film with a double-sided dielectric coating, and one of the dielectric films deposited on the adhesive to the metal film is mechanically separated from the metal film , cut the film into individual cells, and the irreproducible physical marks of glue and metal formed on individual cells are supplied with ayut mesh information with a digital code, covered with a new layer of transparent adhesive film is scanned and as the identification mark is made into the database.

In fig. 1, an identifying non-repeating label is proposed.

As a proof, we present a database of 10 matrices with 100 identification marks in each matrix. In total, the mini tag database presented contains 1000 identification tags with various identifying attributes that are never repeated.
