Abstract
Description
Invenţia se referă la domeniul aplicării marcajelor de identificare, şi anume la procedee de aplicare a marcajelor de identificare pe obiecte, executate atât din materiale electroconductoare, cât şi din materiale dielectrice. The invention refers to the field of application of identification marks, namely to methods of application of identification marks on objects, made of both electroconductive and dielectric materials.
Se cunoaşte un procedeu de identificare a resurselor materiale, care se efectuează prin imprimarea unui număr de identificare, pe care se aplică o grilă informaţională de forma unor figuri geometrice regulate, apoi suprafaţa acesteia se suflă cu un jet de înaltă viteză de gaz cu amestec de particule metalice şi nemetalice [1]. A procedure for identifying material resources is known, which is carried out by printing an identification number, on which an informational grid in the form of regular geometric figures is applied, then its surface is blown with a high-speed jet of gas with a mixture of metallic and non-metallic particles [1].
Dezavantajele acestui procedeu constau în faptul că la viteze ce nu depăşesc viteza sunetului energia cinetică a particulelor este insuficientă pentru încorporarea lor în structura dură a metalelor şi formarea unei matrice individuale. Identificarea gazodinamică este aplicabilă în general pentru formarea matricei individuale din mase plastice şi materiale relativ moi - plumb, aluminiu, bronz, cupru etc. The disadvantages of this process consist in the fact that at speeds that do not exceed the speed of sound, the kinetic energy of the particles is insufficient for their incorporation into the hard structure of the metals and the formation of an individual matrix. Gasodynamic identification is generally applicable for the formation of the individual matrix from plastics and relatively soft materials - lead, aluminum, bronze, copper, etc.
Cea mai apropiată soluţie este un procedeu de identificare a obiectului electroconductor, care include aplicarea pe obiect şi înregistrarea în memoria calculatorului a unei grile de coordonate cu număr de identificare şi a imaginii individuale, obţinute prin acţiunea electrică între obiect şi electrod, cu identificarea ulterioară prin compararea numărului de identificare şi imaginii individuale cu cele înregistrate anterior [2]. The closest solution is a procedure for identifying the electroconductive object, which includes applying to the object and recording in the computer memory a coordinate grid with an identification number and the individual image, obtained by the electrical action between the object and the electrode, with the subsequent identification by comparing the identification number and the individual image with those previously registered [2].
Dezavantajul acestei soluţii constă în faptul că pentru aplicarea imaginii individuale este necesară utilizarea unui aparataj de înaltă tensiune, care poate prezenta pericol pentru personalul tehnic. Pentru susţinerea regimului descărcărilor prin scântei electrice este necesară aplicarea vibraţiei electrodului (obiectului identificării), aceasta de asemenea prezentând pericol pentru personalul tehnic. The disadvantage of this solution lies in the fact that for the application of the individual image it is necessary to use a high-voltage apparatus, which can be dangerous for the technical staff. In order to support the regime of discharges through electric sparks, it is necessary to apply the vibration of the electrode (the object of identification), this also presenting a danger for the technical staff.
Problema pe care o rezolvă invenţia este de a permite aplicarea unei imagini individuale pe obiecte fără a recurge la descărcări electrice şi de a realiza o tehnologie prin excepţie de ordin chimic pentru confecţionarea imaginii individuale. The problem that the invention solves is to allow the application of an individual image on objects without resorting to electrical discharges and to realize a technology by way of chemical exception for making the individual image.
Procedeul de aplicare a marcajelor de identificare pe obiecte, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că include imprimarea pe obiect a unui set de marcaje de identificare, formate din numere de identificare şi grile informaţionale de coordonate, cu aplicarea ulterioară pe acestea a imaginilor nereproductibile, executate prin pulverizarea unui lichid în formă de picături polidisperse cu ajutorul unui dispersor, amplasat deasupra setului de marcaje de identificare. În calitate de lichid este selectată o substanţă, care după uscare formează pe suprafaţa marcajelor pete durabile. În calitate de lichid se selectează o substanţă, care asigură brunarea chimică a suprafeţei lor. În calitate de lichid se utilizează vopsele inlavabile. În calitate de lichid se utilizează vopsele inlavabile de diferite culori. După uscare suprafaţa setului de marcaje de identificare se acoperă cu un strat de material polimer transparent. The process of applying identification marks on objects, according to the invention, removes the disadvantages mentioned above in that it includes the printing on the object of a set of identification marks, consisting of identification numbers and information grids of coordinates, with the subsequent application on them of non-reproducible images, executed by spraying a liquid in the form of polydisperse drops with the help of a disperser, placed above the set of identification marks. A substance is selected as a liquid, which after drying forms permanent stains on the surface of the markings. As a liquid, a substance is selected, which ensures the chemical browning of their surface. Washable paints are used as liquid. Washable paints of different colors are used as liquid. After drying, the surface of the set of identification marks is covered with a layer of transparent polymer material.
Rezultatul invenţiei constă în protejarea codurilor numerice pe obiecte, fără restricţii. The result of the invention consists in protecting the numerical codes on objects, without restrictions.
Invenţia se explică prin desenul din figură, care reprezintă schematic instalaţia pentru aplicarea imaginii individuale pe obiect. The invention is explained by the drawing in the figure, which schematically represents the installation for applying the individual image to the object.
Procedeul constă în faptul că deasupra unui set de marcaje de identificare 1, formate din numere de identificare 2 şi grile informaţionale de coordonate 3, se aplică imagini nereproductibile cu un dispersor 4, care pulverizează un lichid în formă de picături polidisperse 5, iar în calitate de lichid este selectată o substanţă, care după uscare formează pe suprafaţa marcajelor 1 pete durabile. În calitate de dispersor 4 pot fi utilizate pulverizatoare sau duze de injectare de orice construcţie etc. The procedure consists in the fact that on top of a set of identification marks 1, consisting of identification numbers 2 and information grids of coordinates 3, non-reproducible images are applied with a disperser 4, which sprays a liquid in the form of polydisperse drops 5, and as a substance is selected from the liquid, which after drying forms permanent stains on the surface of the markings 1. Sprayers or injection nozzles of any construction, etc., can be used as the disperser 4.
Exemple de realizare Examples of realization
Exemplul 1 Example 1
Pe o suprafaţă plată este în prealabil aplicat setul de marcaje de identificare 1 din aluminiu în formă de matrice de 10x10=100 unităţi. Suprafeţele marcajelor de identificare sunt preventiv degresate şi spălate în apă curgătoare. Pe fiecare imagine sunt aplicate în prealabil numere de identificare 2 şi grile informaţionale de coordonate 3 analogice cu pas similar. Pasul similar al grilei simplifică crearea bazei de date. Deasupra setului de marcaje de identificare 1 este amplasat dispersorul 4 capabil să pulverizeze lichide relativ vâscoase. În calitate de lichid este utilizată soluţia anticorozivă E-Tek pentru brunarea la rece a aluminiului. În calitate de dispersor 4 este utilizată o duză centrifugă. După funcţionarea duzei timp de câteva secunde, picăturile de pe marcajul de identificare 1 sunt lăsate să se usuce definitiv. În urma brunării chimice, pe suprafaţa marcajului de aluminiu apare o serie de pete amplasate haotic, ce formează imaginea. O asemenea identificare, în principiu, nu exclude posibilitatea reproducerii imaginii, însă această tehnologie este extrem de simplă şi ieftină. Protecţia informaţională a codului numeric în varianta descrisă este determinată din considerente economice - contrafacerea manuală a unui asemenea marcaj necesită eforturi, costul cărora va depăşi înzecit beneficiile preconizate în urma lansării articolului contrafăcut. Domeniul de aplicare a procedeului respectiv este producţia în masă a unor mărfuri relativ ieftine, contrafacerea cărora este nerentabilă. Astfel, pentru o suprafaţă de 1 m2, pe care sunt aplicate 10000 de marcaje de identificare cu suprafaţa de 1 cm2, preţul de cost al aplicării imaginii este evaluat la 1,5 USD. On a flat surface, the set of aluminum identification marks 1 is previously applied in the form of a matrix of 10x10=100 units. The surfaces of the identification marks are preventively degreased and washed in running water. Identification numbers 2 and information grids of analog coordinates 3 with a similar step are applied beforehand on each image. The similar step of the grid simplifies the creation of the database. Above the set of identification marks 1 is placed the disperser 4 capable of spraying relatively viscous liquids. E-Tek anti-corrosion solution for cold browning of aluminum is used as liquid. A centrifugal nozzle is used as the disperser 4. After running the nozzle for a few seconds, the drops on the identification mark 1 are allowed to dry completely. After chemical browning, a series of chaotically placed spots appear on the surface of the aluminum marking, forming the image. Such an identification, in principle, does not exclude the possibility of reproducing the image, but this technology is extremely simple and cheap. The informational protection of the numerical code in the described version is determined by economic considerations - the manual counterfeiting of such a marking requires efforts, the cost of which will exceed tenfold the expected benefits following the launch of the counterfeit article. The field of application of the respective process is the mass production of relatively cheap goods, the counterfeiting of which is unprofitable. Thus, for an area of 1 m2, on which 10,000 identification marks with an area of 1 cm2 are applied, the cost price of image application is estimated at 1.5 USD.
Exemplul 2 Example 2
Mărimile geometrice ale marcajelor de identificare coincid cu cele din exemplul 1, însă marcajele respective sunt executate din fier (oţel). În calitate de lichid este utilizată o soluţie de 10% de bicromat de kaliu. Pulverizarea soluţiei apoase cu ajutorul duzei centrifuge nu prezintă nicio dificultate. După uscare, pe locurile unde au nimerit picături rămân pete inlavabile ce formează imaginea. The geometric sizes of the identification markings coincide with those of example 1, but the respective markings are made of iron (steel). A 10% solution of potassium bichromate is used as the liquid. Spraying the aqueous solution using the centrifugal nozzle does not present any difficulty. After drying, washable stains remain on the places where the drops hit, forming the image.
Exemplul 3 Example 3
Dimensiunile geometrice ale marcajelor de identificare coincid cu cele din exemplele precedente. În calitate de pulverizator este utilizată o perie, care la fiecare lovire de o vergea formează sute de picături de diferite dimensiuni. Dacă se utilizează câteva perii şi borcane cu vopsea inlavabilă de diferite culori (preponderent roşie, verde şi albastră), pe marcaj se formează o imagine aproape irepetabilă. Este de dorit să se aştepte uscarea definitivă a picăturilor după aplicarea fiecărei culori. Se poate accelera procesul uscării prin încălzirea marcajelor ori prin iradierea lor cu raze infraroşii. The geometric dimensions of the identification marks coincide with those of the previous examples. A brush is used as a sprayer, which forms hundreds of drops of different sizes with each hit of a rod. If several brushes and jars of washable paint of different colors (mainly red, green and blue) are used, an almost unrepeatable image is formed on the mark. It is desirable to wait for the final drying of the drops after applying each color. The drying process can be accelerated by heating the markings or by irradiating them with infrared rays.
