Description

Traceable resin lens and traceable method and application thereof
Technical Field
The invention belongs to the field of resin lenses, and relates to a traceable resin lens and a traceable method and application thereof.
Background
Resin lenses belong to optical products, and most of the existing tracing methods for resin lenses are in a mode of marking production batch numbers on outer packages. However, after the resin lenses are sold to users, the outer package is discarded after the lenses are matched and mounted, so that the production lot number cannot be traced back only through the resin lenses, unless the resin lenses are inquired, and the inquiry records easily cause the situation of inaccurate traceability. In addition, if the production batch number of the resin lens can be accurately traced, the anti-counterfeiting effect can be achieved, the product can be prevented from being counterfeited, and meanwhile, the error complaint can also be distinguished.
CN112115319A discloses a mold tracing method, a system and an automatic loading manipulator of optical lens molding equipment, the method includes the following steps: establishing a mould tracing information database, and identifying the surface shape characteristics of the mould when the mould reaches a specified position; acquiring a tracing code according to the identification result, and setting tracing information of the lens product according to the corresponding tracing code combined by the mold; obtaining traceability information, searching a mold for preparing a lens product in a mold traceability information database, and outputting the mold; the tracing code comprises a serial number set according to the surface shape characteristics of the die; by adopting the method, the production efficiency of the lens can be further improved, when the lens produced by a single mold has defects, the produced mold and all other lens products produced by the mold can be traced back in time, and other lenses produced by the mold can be withdrawn, isolated or abandoned in time, so that the loss of enterprises is reduced. However, the invention only realizes that the production lot number can be traced back to the corresponding mould when the produced lens has defects, and the production lot number cannot be traced back only through the resin lens.
Therefore, in the art, it is expected to develop a traceable resin lens and a tracing method and application thereof.

Comparative example 1
A resin lens was provided in this comparative example, which differs from example 1 only in that the retroactive agent was not included in the raw materials for the production of the resin lens, and the weight percentage of the resin monomer was 90.2%.
The transmittance spectrum of the resin lens prepared in this comparative example is shown in FIG. 7.
Comparative example 2
The comparative example provides a traceable resin lens, and is different from the example 6 only in that the traceable resin lens is prepared from raw materials, wherein the traceable agent accounts for 3% by weight, and the resin monomer accounts for 94.4% by weight.
The transmittance spectrum of the traceable resin lens prepared in this comparative example is shown in fig. 8.
The spectrograms of the resin lenses provided in the examples and comparative examples were measured using a spectrocolorimeter (trade lab, model: UltraScan PRO) and data were recorded for analysis of the average transmittance in a specific wavelength range, wherein the band limits were determined by comparing the range of wavelengths affected by each absorber before and after addition, and the average transmittance was calculated by averaging the transmittance data at each wavelength in the wavelength range after deriving the data.
The test results are shown in table 1.
TABLE 1
Figure BDA0003215885980000141
Figure BDA0003215885980000151
As can be seen from table 1, when different kinds of absorbers are contained in the resin lenses and the content of the absorbers is different, the spectrogram of the resin lenses and the corresponding transmittance data thereof are different, so that different production batches of the resin lenses can be accurately distinguished. In comparative example 1, since no tracers are added and there is no absorption in the visible and infrared regions, the average transmittance is maximized in the same wavelength range, and it can be seen from fig. 7 that there is no significant characteristic peak in the transmittance spectrum of comparative example 1, and thus the tracing of the resin lens cannot be achieved. In the comparative example 2, the added traceback agent has too high content, so that strong absorption is generated in visible light and infrared regions, the average transmission is relatively low, and the transmittance performance of the resin lens is reduced.
The applicant states that the traceability resin lens and the traceability method and application thereof of the present invention are described by the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must depend on the above embodiments to be implemented. It will be apparent to those skilled in the art that any modification of the present invention, equivalent substitutions of selected materials and additions of auxiliary components, selection of specific modes and the like, which are within the scope and disclosure of the present invention, are contemplated by the present invention.
