Whether correct a kind of polarized spectacle lens of checking install detection method
Technical field
Whether correct a kind of polarized spectacle lens of checking install detection method.
Background technology
Polaroid glasses are made up of two polarization direction different lens.If glasses neglected loading eyeglass or left and right sides eyeglass polarization direction dress are anti-, all can cause the out of use consequence of glasses.
In the past, whether neglected loading and polarization direction were adorned anti-detection and are manually and detect for polarized spectacle lens.Detect manually; Though can effectively realize the technical operation of above-mentioned two test items; But owing to the testing staff can cause mistake behaviour because of reasons such as fatigue, energy dispersion, other factor interference, the generation of above-mentioned phenomenon in the time of can not absolutely stopping polaroid glasses production; When detecting manually simultaneously, because manual operation by ophthalmoscope, can make some problem effectively not detect, thereby cause the generation of false retrieval and omission phenomenon because of hand-held by the difference of ophthalmoscope angle; Moreover; When producing for eyeglass, because the polarized light absorption shaft angle degree offset issue that eyeglass cutting mistake produces, artificial naked eyes also can't directly detect. to sum up; Above problem is all, makes the manual detection mode can't detect the glasses with the said goods quality problems.
Summary of the invention
The objective of the invention is design, make polaroid glasses can realize Equipment Inspection, thereby thoroughly eliminate because of the human factor influence detects effect through a kind of detection method, and the problem that remedies the test item that manual detection can't accomplish.
Detection method of the present invention is: through LED lamp emissive source emitting detection white light, detect white light through passing benchmark polaroid and anaglyph spectacles sheet to be detected, obtain the light transmittance values after white light passes overlapping eyeglass; Should wired the sending to of value read judging/displaying device; Read judging/displaying device with this signal with read judging/displaying device in the standard value of establishing compare; Establish in the standard value range in whether falling into through judging light transmittance values; Produce two kinds of result of determination of right and wrong, and with being presented on the display screen of reading decision maker after two kinds of result of determination digitizings.
Detection method of the present invention is that the technical configuration through following equipment realizes:
Equipment by LED lamp emissive source, benchmark polaroid, light receiver, read judging/displaying device and form; Technical configuration is two for the benchmark polaroid; Be arranged on LED lamp emissive source front end of emission; Leave the technology distance with LED lamp emissive source, the benchmark polarized light piece is glasses to be detected at the back, and glasses to be detected are the light receiver at the back; Distance between benchmark polaroid and the light receiver less than white light energy attenuation distance, is read judging/displaying device and light receiver wired connection greater than the length of seized anaglyph spectacles user mode.
LED lamp emissive source is commercially available white LED lamp, and colour temperature is 4200k-6000k, and power is 3W.
Read judging/displaying device unit, input end, electric signal digital conversion unit, comparing unit being set, reading display unit and form by standard.
So-called technology distance is meant the appropriate distance that can realize that the benchmark polaroid is put.
Use when of the present invention; Glasses to be detected are placed between benchmark polaroid and the light receiver, start LED lamp emissive source, make it launch detection and use white light. detect and pass benchmark polaroid and eyeglass to be detected with white light; Light intensity electric signal with eyeglass to be detected that obtains and benchmark polaroid; Send the electric signal digital conversion unit of reading judging/displaying device to, compare the light intensity electric signal in electric signal digital conversion unit with the standard value that is provided with in advance; And the end value after will comparing converts qualified (OK) and defective (NG) to and manifests the result for two kinds, is presented on the display screen of reading display unit.
The invention enables polaroid glasses can realize becoming manual detection and be Equipment Inspection; Thereby can thoroughly stop false retrieval omission phenomenon because of human factor influence generation; Remedy the angular deviation of polarisation absorption axes; The shortcoming that manual detection can't detect is a much progress of anaglyph spectacles quality control method, has great social significance and market outlook.

Embodiment
Provide an instance at present the present invention done further detailed description:
Embodiment:
LED lamp emissive source 1 is commercially available white LED lamp; Colour temperature is 4200k-6000k; Power is 3W, and benchmark polaroid 2 is opposite with eyeglass polarization direction to be detected, the polaroid that absorption axes is vertical relatively; Light receiver 4 is to be PD15-22T light receiver with the LED lamp emissive source 1 corresponding model that matches; Read judging/displaying device 5 input ends 6 and light receiver 4 wired connections, wherein read electric signal digital conversion unit 7 in the judging/displaying device 5, unit 8, comparing unit 9 are set, read identifying unit 10 and be middle scale central processing unit, display screen 11 is a LCDs.
Benchmark polaroid 2 distance L ED lamp emissive sources 1 10mm, glasses 3 to be detected read judging/displaying device 5 apart from glasses 3 200mm to be detected apart from benchmark polaroid 2 10mm.
Reading the standard range of transmittance value of establishing in the judging/displaying device is 0.05-0.2V.
Through LED lamp emissive source 1 emitting detection white light, colour temperature is 4200k-6000k, and power is 3W, detects white light through passing benchmark polaroid 2 and anaglyph spectacles sheet 3 to be detected, obtains the light transmittance values after white light passes overlapping eyeglass; Should wired the sending to of value read judging/displaying device 5, read judging/displaying device 5 with this signal with read judging/displaying device in the standard value of establishing compare. the correct scope of standard value is 0.05-0.2V.Through judging that light transmittance values is established in the standard value range in whether falling into, and produces two kinds of result of determination of right and wrong, and with after two kinds of result of determination digitizings, is presented on the display screen 11 of reading decision maker.
Read the functional module of the built-in use of judging/displaying device primary control program, be the commercially available standard module and the type of drive of standard.
