Description

Technical Field

[0001] The present invention relates to the field of optical testing technology, and in particular to an optical performance testing device and a testing method thereof. Background Art

[0002] The collimator is used to generate a parallel light beam, which passes through the optical system under test and then passes through the attenuator for light intensity adjustment. The selection of the attenuator should be determined according to the characteristics of the optical system under test and the test requirements to ensure the accuracy of the test results.

[0003] By using a combination of a collimator and an attenuation sheet, the transmittance, reflectance, aberration and other properties of an optical system can be tested. However, during the test, the irradiation range of the collimator is limited, and the test positions of different products are different. During the test, it needs to be adjusted repeatedly, which has certain limitations. At the same time, during the test, different attenuation sheets are sometimes needed. By measuring the output light intensity of the optical system under different attenuation amounts, the transmittance and other key parameters of the optical system can be calculated. However, during the switching process of the existing attenuation sheets, manual adjustment is required, which is relatively cumbersome.

[0080] During use, the fixture of the product to be tested is first installed on the fixture position adjustment component 24, and then the product can be clamped and fixed on the fixture position adjustment component 24 through this fixture. When the product on the fixture position adjustment component 24 needs to be tested through the illumination unit 3, the horizontal movement component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23 and the fixture position adjustment component 24 can be used to achieve multi-axis adjustment of the product, and then it can be adjusted according to different test positions of different products, so that the parallel light beam emitted by the illumination unit 3 can accurately illuminate the test position of the product, thereby achieving the optical performance test of the product.

[0081] In particular, the rack unit 1 comprises:

[0084] The inner frame 11 can support the horizontal moving component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23 and the clamp position adjustment component 24. At the same time, the outer cover 12 is installed on the outside of the inner frame 11, thereby effectively shielding the optical performance test process and preventing external light from affecting the test process. The feed window can be used to facilitate manual loading of products, and the feed window can be closed by an electric sliding window.

[0085] Specifically disclosed, the horizontal moving assembly 21 comprises:

[0086] A base 211, which is fixedly mounted on the inner frame 11;

[0087] A first linear motor 212 is installed horizontally above the base 211, and the first linear motor 212 is transmission-connected to a first slider;

[0091] When the first linear motor 212 is working, the electromagnetic force inside it drives the first slider to move linearly on the outside of the first linear motor 212, which can then drive the movable plate 214 to move laterally, and then drive the product to move laterally. When the second linear motor 215 is working, the electromagnetic force inside it drives the second slider to move linearly on the outside of the second linear motor 215, which can then drive the support plate 217 to move longitudinally, and then drive the product to move longitudinally.

[0098] A stepper motor is installed inside the electric driver 221, and the stepper motor can drive the rotating plate 222 to rotate on the top of the electric driver 221, so that the pad 223 on the rotating plate 222 rotates accordingly, thereby driving the product to rotate at an angle.

[0099] Furthermore, a plurality of induction switches 225 may be optionally fixedly mounted on the outer side of the electric driver 221 , and an induction member 224 may be fixedly mounted on the outer side of the rotating plate 222 .

[0110] It should be emphasized that the working principle of the linear motor is to directly convert electrical energy into mechanical energy of linear motion, and to make the mover move in a linear direction inside the stator through the action of electromagnetic force. This is an existing mature technology, so it will not be described in detail in this embodiment.

[0111] The inner frame 11 can support the horizontal moving component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23 and the clamp position adjustment component 24.

When the product on the fixture position adjustment component 24 needs to be tested by the illumination unit 3;

[0113] When the first linear motor 212 is working, the electromagnetic force inside it drives the first slider to move linearly outside the first linear motor 212, thereby driving the movable plate 214 to move horizontally, thereby driving the product to move horizontally. When the second linear motor 215 is working, the electromagnetic force inside it drives the second slider to move linearly outside the second linear motor 215, thereby driving the support plate 217 to move longitudinally, thereby driving the product to move longitudinally.

[0114] A stepper motor is installed inside the electric driver 221, and the stepper motor can be used to drive the rotating plate 222 to rotate on the top of the electric driver 221, so that the pad 223 on the rotating plate 222 rotates accordingly, thereby driving the product to rotate at an angle; using the set rocking seat motor 233, when the rocking seat motor 233 is working, its output end drives the rotating shaft to rotate, and then drives the rocking seat 232 to rotate relative to the rotating shaft at its end as the axis through the rotating shaft, so that the deflection angle of the product can be adjusted; using the set mounting block 242, the product fixture can be installed and fixed, and through the set third linear motor 241, when the third linear motor 241 is working, the electromagnetic force inside it drives the third slider to move linearly on the outside of the third linear motor 241, thereby driving the product to move accordingly.

[0115] Furthermore, the horizontal moving component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23 and the fixture position adjustment component 24 can be used to achieve multi-axis adjustment of the product, and can be adjusted according to different test positions of different products, so that the parallel light beam emitted by the illumination unit 3 can accurately illuminate the test position of the product, thereby achieving the optical performance test of the product.

[0117] Step 1: Install the fixture of the product to be tested on the fixture position adjustment component 24, so that the product can be clamped and fixed on the fixture position adjustment component 24 by the fixture;

[0119] Step 3. After the adjustment is completed, the parallel light beam can be emitted by the parallel light tube assembly 31, so that the parallel light beam can accurately illuminate the test position of the product. Then, the attenuation plate switching assembly 32 is used to adjust the light intensity of the parallel light beam, and the optical performance test is achieved after the product is illuminated at different light intensities.
