Description
Invenţia se referă la domeniul de identificare a resurselor materiale şi poate fi utilizată la marcarea pieselor electroconductoare, de exemplu, la producerea laminatului, a pieselor mijloacelor de transport, în industria construcţiilor de maşini şi avioane. The invention refers to the field of identification of material resources and can be used to mark electroconductive parts, for example, in the production of laminate, parts of means of transport, in the car and aircraft construction industry.
Se cunoaşte un procedeu de aplicare a nanomarcajului de identificare nedetaşabil, care constă în formarea unei imagini individuale prin turnarea într-un şliţ a unui praf ultradispers, încălzirea şi sinterizarea acestuia sub presiune, aplicarea unei grile informaţionale pe imaginea individuală obţinută şi a unui cod numeric de identificare lângă aceasta [1]. A procedure for applying the non-removable identification nanomarking is known, which consists in the formation of an individual image by pouring an ultradisperse powder into a slot, heating and sintering it under pressure, applying an informational grid on the obtained individual image and a numerical code of identification next to it [1].
Dezavantajele acestui procedeu constau în necesitatea utilizării unei cantităţi considerabile de praf ultradispers, utilizarea presiunilor înalte şi consumul mare de energie pentru încălzirea întregului marcaj de identificare. The disadvantages of this process are the need to use a considerable amount of ultradisperse powder, the use of high pressures and the high energy consumption for heating the entire identification mark.
Cea mai apropiată soluţie este un procedeu de identificare a obiectului electroconductor, care constă în imprimarea pe acesta a unui număr de identificare, aplicarea mecanică a unei grile informaţionale şi a unei imagini individuale, obţinute prin descărcare electrică punctiformă între obiect şi un electrod vibrant [2]. The closest solution is a procedure for identifying the electroconductive object, which consists in printing on it an identification number, the mechanical application of an informational grid and an individual image, obtained by point-like electric discharge between the object and a vibrating electrode [2 ].
Dezavantajul procedeului cunoscut constă în aceea că descărcarea electrică nu asigură o mare varietate de imagini individuale, în particular, nu asigură distribuirea aleatorie a prafurilor de diferite dimensiuni. The disadvantage of the known method is that the electrical discharge does not provide a wide variety of individual images, in particular, it does not provide a random distribution of dusts of different sizes.
Problema pe care o rezolvă invenţia constă în majorarea nivelului de protecţie informaţională a marcajului de identificare. The problem that the invention solves consists in increasing the level of informational protection of the identification mark.
Procedeul, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că pe suportul metalic se execută un cod numeric şi o grilă informaţională de coordonate, pe care se formează o imagine individuală prin aplicarea pe suportul metalic a unui strat neuniform de praf metalic cu particule de dimensiuni diferite, plasarea pe acesta a unei plăci transparente de fixare a stratului de praf metalic, iradierea neuniformă a prafului cu laser, cu densitatea fluxului de radiaţie de 105…106 W/cm2, înlăturarea plăcii transparente de fixare şi a particulelor nefixate. The process, according to the invention, removes the disadvantages mentioned above in that a numerical code and an information grid of coordinates are executed on the metal support, on which an individual image is formed by applying to the metal support a non-uniform layer of metal dust with particles of different sizes, placing on it a transparent plate for fixing the metal dust layer, unevenly irradiating the dust with a laser, with a radiation flux density of 105...106 W/cm2, removing the transparent fixing plate and unfixed particles.
După înlăturarea plăcii transparente de fixare şi a particulelor nefixate, pe imaginea individuală poate fi aplicat un strat protector transparent. After removing the clear mounting plate and unfixed particles, a clear protective layer can be applied to the individual image.
Invenţia se explică prin desenele din fig. 1-5, care reprezintă: The invention is explained by the drawings in fig. 1-5, which represent:

Procedeul se efectuează după cum urmează. The procedure is carried out as follows.
Pe suportul metalic se execută, de exemplu, cu instrumente de gravat sau de lovire cu ace codul numeric 3 şi cu maşina de frezat - grila informaţională 4. După aceasta pe grila informaţională 4 se aplică un strat neuniform de praf metalic cu particule de dimensiuni diferite şi se iradiază cu laser 6 cu densitatea fluxului de radiaţie de 105…106 W/cm2 (fig. 5) printr-o placă transparentă de fixare a stratului de praf metalic 10, formând imaginea individuală 5 pe grila informaţională 4. The numerical code 3 is executed on the metal support, for example, with tools for engraving or punching with needles, and with the milling machine - the informational grid 4. After this, an uneven layer of metal dust with particles of different sizes is applied to the informational grid 4 and is irradiated with a laser 6 with a radiation flux density of 105...106 W/cm2 (fig. 5) through a transparent plate for fixing the metal dust layer 10, forming the individual image 5 on the information grid 4.
Dispozitivul de control 7 permite iradierea neuniformă a prafului cu laser atât prin deplasarea laserului 6, cât şi prin deplasarea în spaţiu a sistemului optic 9. The control device 7 allows the non-uniform irradiation of the laser dust both by moving the laser 6 and by moving the optical system 9 in space.
În această variantă imaginea individuală 5 se formează din particulele de pulbere sudate de dimensiuni diferite, iar la necesitate şi de culori diferite. Apoi placa de fixare 10 este înlăturată şi, dacă este necesar, pentru protecţia împotriva mediilor agresive, pe imaginea individuală 5 se aplică un email transparent, formând un strat nedetaşabil de la imaginea individuală 5. Emailul în acest caz îndeplineşte şi o altă funcţie - fixează particulele slab fixate. Ultimele pot apărea din cauza temperaturilor scăzute şi a utilizării unui amestec de prafuri din materiale cu temperaturi de topire diferite. In this variant, the individual image 5 is formed from the welded powder particles of different sizes and, if necessary, of different colors. Then the fixing plate 10 is removed and, if necessary, for protection against aggressive environments, a transparent enamel is applied to the individual image 5, forming a non-removable layer from the individual image 5. The enamel in this case also fulfills another function - it fixes loosely fixed particles. The latter can occur due to low temperatures and the use of a mixture of dusts from materials with different melting temperatures.
Poziţiile particulelor amplasate imprevizibil şi sudate pe suprafaţa grilei informaţionale de coordonate 4 (imaginea individuală 5) se introduc în baza de date. The positions of the particles placed unpredictably and welded on the surface of the informational coordinate grid 4 (individual image 5) are entered into the database.
Exemplul 1 Example 1
Suportul metalic a fost executat din oţel inoxidabil cu grosimea de 2 mm. Codul numeric şi grila informaţională de coordonate au fost aplicate prin gravare cu laser CO2 al companiei ULS (Universal Laser Systems Inc.). Diametrul punctului iradiat cu laser era de cca 50 µm. The metal support was made of stainless steel with a thickness of 2 mm. The numerical code and the information grid of coordinates were applied by CO2 laser engraving of the company ULS (Universal Laser Systems Inc.). The diameter of the point irradiated with the laser was about 50 µm.
Aplicarea pe grila informaţională a particulelor de cupru s-a realizat manual cu pensula. Placa transparentă de fixare era confecţionată din sticlă optică de cuarţ cu grosimea de 8 mm. Densitatea fluxului de radiaţie estimată la suprafaţa suportului metalic a fost de 105 W/cm2. După iradierea neuniformă a suportului metalic cu laser CO2, placa transparentă de fixare a fost înlăturată şi suprafaţa marcajului de identificare obţinut a fost prelucrată cu aspiratorul. Ca rezultat, pe marcajul de identificare rămâneau nu mai mult de 15% din numărul iniţial de particule de cupru. The application of the copper particles on the informational grid was done manually with a brush. The transparent fixing plate was made of optical quartz glass with a thickness of 8 mm. The radiation flux density estimated at the surface of the metal support was 105 W/cm2. After unevenly irradiating the metal support with CO2 laser, the transparent fixing plate was removed and the surface of the obtained identification mark was vacuumed. As a result, no more than 15% of the initial number of copper particles remained on the identification mark.
La iradierea prafului cu densitatea fluxului de radiaţie de 8·104 W/cm2, numărul particulelor de cupru fixate a fost minim, deoarece se fixau bine în special particulele de cupru de dimensiuni minime. Uneori numărul particulelor fixate nu depăşea câteva unităţi, ceea ce era insuficient pentru crearea marcajului de identificare. La iradierea prafului cu densităţi ale fluxului de radiaţie mai mari de 105 W/cm2, numărul particulelor de cupru fixate pe suprafaţa suportului metalic depăşea 100…150 unităţi, ceea ce este suficient pentru identificarea sigură a obiectului. When irradiating the dust with a radiation flux density of 8·104 W/cm2, the number of fixed copper particles was minimal, because copper particles of minimum size were fixed well. Sometimes the number of fixed particles did not exceed a few units, which was insufficient to create the identification mark. When irradiating dust with radiation flux densities higher than 105 W/cm2, the number of copper particles fixed on the surface of the metal support exceeded 100...150 units, which is sufficient for the safe identification of the object.
Exemplul 2 Example 2
Suportul metalic a fost executat din bronz cu grosimea de 4 mm. Codul numeric şi grila informaţională de coordonate au fost aplicate prin gravare cu laser CO2 al companiei ULS (Universal Laser Systems Inc.). Diametrul punctului iradiat cu laser varia în limitele 50…80 µm. Aplicarea pe grila informaţională a particulelor de cupru s-a realizat manual cu pensula. Placa transparentă de fixare era confecţionată din sticlă optică de cuarţ cu grosimea de 8 mm. Densitatea fluxului de radiaţie estimată la suprafaţa suportului metalic a fost de 105 W/cm2. După iradierea neuniformă a suportului metalic cu laser CO2, placa transparentă de fixare a fost înlăturată şi suprafaţa marcajului de identificare obţinut a fost prelucrată cu aspiratorul. Ca rezultat, pe marcajul de identificare rămâneau peste 40% din numărul iniţial al particulelor de cupru. The metal support was made of bronze with a thickness of 4 mm. The numerical code and the information grid of coordinates were applied by CO2 laser engraving of the company ULS (Universal Laser Systems Inc.). The diameter of the point irradiated with the laser varies between 50...80 µm. The application of the copper particles on the informational grid was done manually with a brush. The transparent fixing plate was made of optical quartz glass with a thickness of 8 mm. The radiation flux density estimated at the surface of the metal support was 105 W/cm2. After unevenly irradiating the metal support with CO2 laser, the transparent fixing plate was removed and the surface of the obtained identification mark was vacuumed. As a result, more than 40% of the initial number of copper particles remained on the identification mark.
Utilizarea materialelor mai puţin refractare pentru confecţionarea suportului metalic al marcajului de identificare are un efect pozitiv asupra numărului de particule de cupru fixate. The use of less refractory materials for the manufacture of the metal support of the identification mark has a positive effect on the number of fixed copper particles.
Exemplul 3 Example 3
Suportul metalic este executat din aliaj de aluminiu (5…10%) şi cupru (90…95%) de culoare galben-aurie. Ca praf a fost selectat un praf oxidat din oţel inoxidabil de culoare întunecată. La iradierea cu densitatea fluxului de radiaţie de cca 8·105 W/cm2, particulele de praf se fixau sigur pe marcajul de identificare. The metal support is made of aluminum alloy (5...10%) and copper (90...95%) of yellow-gold color. A dark colored oxidized stainless steel powder was selected as the dust. When irradiated with a radiation flux density of about 8·105 W/cm2, the dust particles were securely fixed on the identification mark.
Exemplul 4 Example 4
Toate dimensiunile şi materialele coincid cu cele din exemplul 3. La iradierea cu densitatea fluxului de radiaţie de peste 106 W/cm2 particulele de praf erau fixate sigur pe marcajul de identificare, dar se observa topirea particulelor şi pierderea clarităţii formei, ceea ce reduce posibilitatea identificării. All dimensions and materials coincide with those of example 3. When irradiated with a radiation flux density of more than 106 W/cm2, the dust particles were securely fixed on the identification mark, but melting of the particles and loss of shape clarity is observed, which reduces the possibility of identification .
Exemplele de mai sus confirmă că intervalul selectat de densităţi ale fluxului de radiaţie de 105…106 W/cm2 asigură fixarea sigură a particulelor de metal pe marcajul de identificare. The above examples confirm that the selected range of radiation flux densities of 105…106 W/cm2 ensures secure fixation of the metal particles on the identification mark.
Cu cât mai variate sunt imaginile individuale 5 obţinute, cu atât mai sigură este protecţia informaţională a codului numeric 3 şi, prin urmare, mai înaltă este fiabilitatea procesului de identificare a obiectului material 1. The more varied the individual images 5 obtained, the more secure is the informational protection of the numerical code 3 and, therefore, the higher is the reliability of the identification process of the material object 1.
După formarea imaginii individuale 5, marcajul de identificare 2 cu codul numeric 3 şi imaginea individuală 5 se introduc în baza de date. Căutarea în baza de date se realizează după codul numeric 3, iar posibilitatea modificării codului numeric este complet exclusă datorită imaginii individuale 5. Procesul de identificare se finalizează după coinciderea deplină a imaginii individuale 5 de pe obiectul 1 cu imaginea individuală 5 a acestuia din baza de date. After the formation of the individual image 5, the identification mark 2 with the numerical code 3 and the individual image 5 are entered into the database. The search in the database is carried out according to the numerical code 3, and the possibility of changing the numerical code is completely excluded due to the individual image 5. The identification process is completed after the complete coincidence of the individual image 5 on the object 1 with its individual image 5 in the database data.
Luând în consideraţie faptul că codul numeric 3 poate fi executat pe suportul metalic cu gravorul cu laser, tehnologia propusă are avantaje semnificative faţă de celelalte, pentru că se execută cu acelaşi tip de echipament. Considering the fact that numerical code 3 can be executed on the metal support with the laser engraver, the proposed technology has significant advantages over the others, because it is executed with the same type of equipment.
