[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0022] See also Figures 1 to 4An optical corrective lens with an anti-counterfeiting two-dimensional code is shown, comprising a lens body 10, at least one anti-counterfeiting two-dimensional code 20 is arranged on the convex surface 11 of the lens body 10, and an anti-counterfeiting two-dimensional code 20 is arranged on the surface of the anti-counterfeiting two-dimensional code 20. The anti-reflection film layer 30 has an anti-reflection effect, so that the anti-counterfeiting two-dimensional code 20 is easier to read in different environments and is not affected by external factors, making scanning the code simpler and more convenient, avoiding situations such as being unable to scan and read, reducing consumer complaints, and increasing product satisfaction.

[0023] In this embodiment, the information that can be stored in the anti-counterfeiting two-dimensional code 20 includes the production date, manufacturer, brand introduction, sales area, degree, diameter, traceability information, etc. of the lens. After the consumer purchases the lens, by scanning the anti-counterfeiting two-dimensional code 20 on the lens, the consumer first knows the reliability of the lens, and also increases the recognition of the high-end product. At the same time, by filling in the consumer's information, the manufacturer can count the products purchased by the consumer, so that the consumer can trace and feedback in the future. The manufacturer can effectively control a series of tasks that were originally counted manually, such as sales area, sales statistics, complaint statistics, etc.

[0024] The anti-counterfeiting two-dimensional code 20 is set on the edge of the convex surface 11 of the lens body. The anti-counterfeiting two-dimensional code 20 in this embodiment includes a pair, and the pair of anti-counterfeiting two-dimensional codes 20 are symmetrically set on the edge of the convex surface 11 of the lens body about the center of the lens. Since the pair of anti-counterfeiting two-dimensional codes 20 are symmetrically set at different positions, when one of the anti-counterfeiting two-dimensional codes 20 is difficult to scan due to reflection caused by the light angle or other environmental factors, the other anti-counterfeiting two-dimensional code 20 is further avoided due to the different position. The anti-counterfeiting two-dimensional code 20 in this embodiment is formed on the convex surface 11 of the lens body by a laser engraving machine, and the depth of the anti-counterfeiting two-dimensional code 20 is 0.05-0.5mm and the side length is 4-10mm.

[0025] The anti-reflection film layer 30 of this embodiment includes an evaporation layer, and the evaporation layer is arranged on the surface of the anti-counterfeiting two-dimensional code in a fan-shaped structure. The thickness of the anti-reflection film layer 30 is 30nm to 150nm. The evaporation process is fan-shaped, which can increase the amount of evaporation each time, so that the evaporation process is a batch processing state. When the medicinal materials are evaporated, the heat source will disperse the medicinal materials in a fan-shaped manner. Therefore, in order to make the surface of the two-dimensional code more evenly covered with the anti-reflection film layer during the entire evaporation, the entire evaporation is carried out in a fan-shaped manner.

[0026] In order to further improve the anti-counterfeiting effect of the utility model, at least one invisible mark 40 is provided on the convex surface 11 of the lens body, and an anti-reflection film layer 30 is provided on the surface of the invisible mark 40. The invisible mark 40 is formed on the convex surface 11 of the lens body by a laser engraving machine, and the invisible mark 40 includes a text-type invisible mark, and its depth is 0.02-0.1mm. The invisible mark plays a preliminary anti-counterfeiting effect, and the anti-counterfeiting two-dimensional code plays an enhanced anti-counterfeiting effect such as anti-counterfeiting and tracing, and further reduces the risk of imitation.

[0027] The utility model forms an independent anti-counterfeiting two-dimensional code 20 according to the customer's requirements and required content, and connects to the receiving end of the engraving device through the two-dimensional code generation system, so that the engraving device performs the engraving action after receiving the information. After the engraving device is finished, it automatically feeds back to the two-dimensional code generation system, and uploads this two-dimensional code information to the customer's production and sales tracing system, forming a set of rigorous anti-counterfeiting production links. The two-dimensional code anti-counterfeiting technology of the utility model can achieve universality in the lens industry, regardless of the lens material, lens curvature, and lens size, it can be quickly universal according to customer needs.

[0028] The preparation process of the utility model is as follows:

[0029] 1. The lens manufacturer forms a dot matrix QR code and text invisible mark according to its own requirements.

[0030] 2. Interact with the recognition and selection software of the deep ultraviolet laser engraving machine through data transmission.

[0031] 3. Place the lens in the working area, turn on the laser engraving machine and select the required QR code and invisible mark.

[0032] 4. Start engraving. The equipment automatically identifies the lens height and diameter through the visual recognition system and infrared laser detection and positioning system, and calculates a series of engraving parameters such as engraving position, engraving height, and engraving power.

[0033] 5. The mechanical part of the equipment reaches the engraving conditions according to the equipment instructions. By focusing the light spot, a square QR code engraving work with a depth of 0.05-0.5mm and a size of 4-10mm is completed within 3-10 seconds. The laser power of the UV laser engraving machine in this step is 3-10W, and the wavelength is 285-355nm. The UV light focusing spot is extremely small, and the processing heat effect is minimal. The UV laser engraving machine uses visual recognition and infrared distance detection functions. The software automatically identifies the lens height and transmits it to the mechanical part of the equipment. The screw controls the lifting and lowering of the laser head. The marking software automatically sets the marking frequency according to the feedback marking distance, and then laser engraves the corresponding points on the convex surface of the lens.

[0034] 6. The equipment can also engrave text-type invisible marks according to the selected requirements, and complete the engraving of an invisible mark with a depth of 0.02mm to 0.1mm within 2 to 5 seconds.

[0035] 7. After completing the QR code engraving process, the lens is sent to a polymer vacuum coating machine. After the vacuum of the coating machine reaches an appropriate pressure, the anti-reflection medicinal material is heated by an electron gun, and the surface of the lens is fan-shaped evaporated to form an anti-reflection film with a thickness of 30nm to 150nm on the surface.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
