Description

Technical Field

[0001] This invention relates to the field of optical testing technology, specifically to an optical performance testing device and its testing method. Background Technology

[0002] A collimator is used to generate a parallel light beam. This beam passes through the optical system under test and is then adjusted for intensity by an attenuator. The choice of attenuator should be determined based on the characteristics of the optical system under test and the testing requirements to ensure the accuracy of the test results.

[0003] By combining a collimator and an attenuator, the transmittance, reflectance, aberration, and other properties of an optical system can be tested. However, during the testing process, the illumination range of the collimator is limited, and the test positions vary for different products, requiring repeated adjustments during testing, which has certain limitations. Furthermore, different attenuators are sometimes needed during testing, and by measuring the output light intensity of the optical system under different attenuation levels, key parameters such as transmittance can be calculated.

Detailed Implementation

[0066] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0067] Example 1

[0068] This invention discloses an optical performance testing device and a testing method thereof.

[0069] According to the attached Figure 1 As shown in -11, it includes:

[0070] Rack Unit 1;

[0071] A multi-axis adjustment unit 2 is installed inside the frame unit 1, and the multi-axis adjustment unit 2 includes:

[0072] The clamp position adjustment assembly 24 has a clamp for holding the product mounted on it, and the position of the clamp can be adjusted.

[0073] The deflection angle adjustment component 23 is connected to the clamp position adjustment component 24 and is used to adjust the deflection angle of the clamp position adjustment component 24.

[0074] A horizontal angle adjustment component 22 is disposed below the deflection angle adjustment component 23 and is used to adjust the horizontal angle of the deflection angle adjustment component 23.

[0075] A horizontal movement component 21 is disposed below the horizontal angle adjustment component 22 and is used to adjust the horizontal position of the horizontal angle adjustment component 22;

[0076] The horizontal movement component 21, the horizontal angle adjustment component 22, and the deflection angle adjustment component 23, together with the fixture position adjustment component 24, enable multi-axis adjustment of the product.

[0077] The illumination unit 3 is installed inside the frame unit 1 and is located behind the clamp position adjustment assembly 24. The illumination unit 3 includes:

[0078] The collimator assembly 31 is capable of emitting a parallel beam of light toward the product, and using the parallel beam of light to illuminate the product to achieve optical performance testing of the product.

[0079] The attenuator switching component 32 is located at the emitting end of the collimator component 31 and is used to adjust the illumination intensity of the collimator beam.

[0080] During use, the fixture for the product to be tested is first installed on the fixture position adjustment component 24. The product can then be clamped and fixed on the fixture position adjustment component 24 by this fixture. When the product on the fixture position adjustment component 24 needs to be tested by 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 realize multi-axis adjustment of the product. This allows for adjustments according to different test positions of different products, so that the parallel beam emitted by the illumination unit 3 can accurately illuminate the test position of the product, thereby realizing the optical performance test of the product.

[0081] Specifically disclosed, rack unit 1 includes:

[0082] Inner rack 11;

[0083] The outer cover 12 is installed on the outside of the inner frame 11. The front of the outer cover 12 is provided with a feeding window, and the feeding window is provided with an electric sliding window.

[0084] The inner frame 11 provides support for the horizontal movement component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23, and the clamp position adjustment component 24. Meanwhile, the outer cover 12 is installed on the outside of the inner frame 11, which effectively shields the optical performance testing process and prevents external light from affecting the testing process. The feed window facilitates manual loading of products and can be closed by an electric sliding window.

[0085] Specifically disclosed, the horizontal movement component 21 includes:

[0086] The base 211 is fixedly installed on the inner frame 11;

[0087] The first linear motor 212 is horizontally mounted above the base 211, and the first linear motor 212 is connected to the first slider.

[0088] The movable plate 214 is slidably disposed above the first linear motor 212, and the movable plate 214 is fixedly connected to the first slider;

[0089] The second linear motor 215 is mounted longitudinally above the movable plate 214, and the second linear motor 215 is connected to the second slider.

[0090] The support plate 217 is slidably disposed above the second linear motor 215, and the support plate 217 is fixedly connected to the second slider.

[0091] 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, which in turn drives the movable plate 214 to move laterally, and thus drives 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 outside the second linear motor 215, which in turn drives the support plate 217 to move longitudinally, and thus drives the product to move longitudinally.

[0092] Furthermore, a first auxiliary rail 213 is fixedly connected above the base 211, and a movable plate 214 is slidably disposed above the first auxiliary rail 213. A second auxiliary rail 216 is fixedly connected above the movable plate 214, and a support plate 217 is slidably disposed above the second auxiliary rail 216.

[0093] By utilizing the first auxiliary rail 213 and the second auxiliary rail 216, the movable plate 214 and the support plate 217 can be supported respectively, making the movable plate 214 and the support plate 217 more stable during the sliding process.

[0094] Specifically disclosed, the horizontal angle adjustment component 22 includes:

[0095] Electric actuator 221 is fixedly mounted above support plate 217;

[0096] Rotating plate 222, which is mounted on the top output end of electric drive 221;

[0097] The pad 223 is fixedly installed above the rotating plate 222.

[0098] The electric driver 221 is equipped with a stepper motor, which drives the rotating plate 222 to rotate on the top of the electric driver 221, thereby causing the pad 223 on the rotating plate 222 to rotate, and thus driving the product to rotate at an angle.

[0099] Furthermore, multiple inductive switches 225 can be optionally fixedly installed on the outside of the electric actuator 221, and a sensing element 224 is fixedly installed on the outside of the rotating plate 222. The electric actuator 221 drives the rotating plate 222 to rotate, which can move the sensing element 224 into the inductive switch 225.

[0100] By utilizing the sensor 224 and the sensor switch 225, it is convenient to control the rotating plate 222 to rotate to different angles.

[0101] Specifically disclosed, the deflection angle adjustment component 23 includes:

[0102] The fixed platform 231 is fixedly installed on the top of the pad 223;

[0103] The rocker base 232 is rotatably mounted inside the fixed platform 231 via a rotating shaft;

[0104] The rocking seat motor 233 is fixedly installed on the outside of the fixed platform 231, and the output end of the rocking seat motor 233 is fixedly connected to the rotating shaft.

[0105] By 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 the rotating shaft drives the rocking seat 232 to rotate relative to the rotating shaft at its end as the axis, thereby enabling the adjustment of the product's deflection angle.

[0106] Specifically disclosed, the clamp position adjustment assembly 24 includes:

[0107] The third linear motor 241 is fixedly mounted on the rocker base 232, and the third linear motor 241 is connected to the third slider in a transmission connection.

[0108] Mounting block 242 is fixedly mounted on the outside of the third slider, and mounting holes for mounting clamps are provided on mounting block 242.

[0109] The product can be fixed in place by using the mounting block 242. When the third linear motor 241 is working, the electromagnetic force inside the third linear motor 241 drives the third slider to move linearly outside the third linear motor 241, thereby moving the product accordingly.

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

[0111] The inner frame 11 provides support for the horizontal movement component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23, and the clamp position adjustment component 24. Meanwhile, the outer cover 12 is installed on the outside of the inner frame 11, which effectively shields the optical performance testing process and prevents external light from affecting the testing process. The feed window facilitates manual loading of products and can be closed by an electric sliding window.

[0112] During use, the fixture for the product to be tested is first installed 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. When the product on the fixture position adjustment component 24 needs to be tested by the light 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, which in turn drives the movable plate 214 to move laterally, and thus drives 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 outside the second linear motor 215, which in turn drives the support plate 217 to move longitudinally, and thus drives the product to move longitudinally.

[0114] The electric driver 221 is equipped with a stepper motor, which drives the rotating plate 222 to rotate on top of the electric driver 221. This causes the pad 223 on the rotating plate 222 to rotate, thereby rotating the product at an angle. The rocker motor 233 drives the rotating shaft to rotate when it is working. This rotating shaft drives the rocker 232 to rotate relative to the rotating shaft at its end, thereby adjusting the deflection angle of the product. The mounting block 242 is used to install and fix the product in a clamp. The third linear motor 241 drives the third slider to move linearly outside the third linear motor 241 when it is working, thereby moving the product accordingly.

[0115] Furthermore, 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. This allows for adjustments based on different test positions of different products, ensuring that the parallel beam emitted by the illumination unit 3 can accurately illuminate the test position of the product, thereby achieving optical performance testing of the product.

[0116] A testing method for an optical performance testing device includes the following steps:

[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 this fixture;

[0118] Step 2: When it is necessary to test the product on the fixture position adjustment component 24 through the illumination unit 3, the multi-axis adjustment of the product can be achieved by using the horizontal movement component 21, the horizontal angle adjustment component 22, the deflection angle adjustment component 23 and the fixture position adjustment component 24 according to the different test positions of different products.

[0119] Step 3: After adjustment, the parallel light tube assembly 31 can emit a parallel light beam, which can accurately illuminate the test position of the product. Then, the attenuator switching assembly 32 is used to adjust the light intensity of the parallel light beam. After illuminating the product with different light intensities, its optical performance is tested.

[0126] The deflection angle adjustment component 23 is connected to the clamp position adjustment component 24 and is used to adjust the deflection angle of the clamp position adjustment component 24.

[0127] A horizontal angle adjustment component 22 is disposed below the deflection angle adjustment component 23 and is used to adjust the horizontal angle of the deflection angle adjustment component 23.

[0129] The horizontal movement component 21, the horizontal angle adjustment component 22, and the deflection angle adjustment component 23, together with the fixture position adjustment component 24, enable multi-axis adjustment of the product.

[0130] The illumination unit 3 is installed inside the frame unit 1 and is located behind the clamp position adjustment assembly 24. The illumination unit 3 includes:

[0131] The collimator assembly 31 is capable of emitting a parallel beam of light toward the product, and using the parallel beam of light to illuminate the product to achieve optical performance testing of the product.

[0132] The attenuator switching component 32 is located at the emitting end of the collimator component 31 and is used to adjust the illumination intensity of the collimator beam.

[0133] Specifically disclosed, the collimator assembly 31 includes:

[0134] Mounting base 311 is fixedly mounted on inner frame 11;

[0135] The light source housing 312 is fixedly installed above the mounting base 311, and the light source housing 312 is mounted on the outside of the light source tube 313. The light source inside the light source housing 312 emits a parallel light beam, which then passes through the light source tube 313 and is emitted out.

[0136] Specifically disclosed, the attenuator switching component 32 includes:

[0137] Support frame 321 is fixedly installed on inner frame 11;

[0138] Mounting strip 322 is fixedly connected to the front of support frame 321;

[0140] Mounting plate 325, with its top fixedly connected to connecting plate 323, and multiple attenuation plates 326 optionally mounted on mounting plate 325, the multiple attenuation plates 326 being arranged horizontally in sequence.

[0141] Using the attenuator 326, the parallel light emitted from the light tube 313 passes through the attenuator 326 and illuminates the product. The attenuator 326 can adjust the brightness, uniformity, and intensity distribution of the light source. When different attenuators 326 with different attenuation effects are required, the fourth linear motor 324 is turned on. The electromagnetic force inside the motor drives the fourth slider to move linearly outside the motor. Then, the connecting plate 323 drives the mounting plate 325 to move linearly, so that another attenuator 326 moves to the light-emitting end of the light tube 313, thereby realizing the switching of the attenuator 326.
