[0021] In order to solve the problem that the existing optical product test can only test one product at the same time due to the FOV problem, and increasing the test equipment will cause the production test cost to be high, the present application provides an optical product test device and method, which comprises a rotating support, a plurality of two groups of environment modules and a feeding and discharging module arranged on the periphery of the rotating support. The rotating support can drive each test module to rotate, so as to realize the feeding and discharging and detection of the test modules under multiple environmental conditions, and the product test efficiency can be effectively improved.

[0022] Figure 1 The schematic structure of the optical product test device according to the embodiment of the present application is shown; Figures 2 to 4 The schematic structure of the local component of the optical product test device according to the embodiment of the present application is shown from different angles.

[0023] Combined Figures 1 to 4As shown, the optical product testing device 100 provided by the present application comprises a rotating support 1, at least two groups of environment modules and feeding and discharging modules arranged on the periphery of the rotating support 1; wherein each group of environment modules comprises at least two different test environments, and a plurality of test modules are uniformly arranged on the rotating support 1, and at least one optical product to be tested is positioned in each test module, when the test modules are rotated to different test environments, the related tests of the optical product in the current environment can be realized, that is, the test modules are rotated by the rotating support 1, and the feeding and discharging modules are used to feed and discharge the test modules in rotation, and the optical products to be tested in each test module are tested in different test environments, by arranging a plurality of feeding and discharging modules, a plurality of test environments and a plurality of test modules, the synchronous optical test of multiple products and multiple environments can be realized.

[0024] In order to further improve the test efficiency and test quality of the optical product, the test module can comprise a plurality of test cavities arranged in an array and independent of each other, a corresponding reflection plate is arranged in each test cavity, and a driving assembly is arranged to drive the reflection plate to move, in the test process, the optical product can be positioned above each test cavity by a plurality of ways such as a hollow limiting plate, then according to the test environment, the optical product to be tested or the test requirement, the test position of the reflection plate in the corresponding test cavity is adjusted by the driving assembly, and then the related test of the optical product is completed.

[0025] In addition, for the same type of optical product, the position and type of the reflection plate in the corresponding test cavity can be the same, for different optical products, or different parameters of optical test of the same type of optical product, the position of the reflection plate can be adjusted according to the actual demand and the appropriate reflection plate is used, such as a 18% reflectivity diffuse reflection plate, since each test cavity in the test module is independent of each other, the independent optical test of multiple same or different products can be realized by one test module, so that the test efficiency is improved, and the test demand of diversity can also be met, which is suitable for multiple types of optical products.

[0026] As shown in Figure 2 and Figure 3 As shown, the test cavity can adopt a 2x2 hole as shown in Figure 2 (a), a 3x3 hole as shown in Figure 2 (b), a 4x4 hole as shown in Figure 2 (c), a 5x5 hole as shown in Figure 2 (d), and the reflection plate 3 can be positioned in the corresponding test cavity to move to meet various test requirements of the optical product.

[0027] In the optical product testing device of the present application, the number of groups of the environment module and the feeding and discharging module is consistent, and the testing movement of the testing module in different environment modules is synchronous, in other words, by setting multiple groups of the environment module and the feeding and discharging module, parallel execution of two groups of testing can be realized, and each group of testing can further realize related testing of multiple products in multiple testing environments.

[0028] Specifically, the feeding and discharging module includes a first feeding and discharging module and a second feeding and discharging module, the environment module includes a first environment module and a second environment module, the first environment module includes a first testing environment (testing environment 11), a second testing environment (testing environment 12) and a third testing environment (testing environment 13) arranged in sequence, and the second environment module includes a fourth testing environment (testing environment 21), a fifth testing environment (testing environment 22) and a sixth testing environment (testing environment 23) arranged in sequence. Since each testing environment and the feeding and discharging module are stationary, in order to facilitate feeding and discharging of the optical product and testing cycle, the first testing environment can be arranged corresponding to the position of the first feeding and discharging module, and the fourth testing environment can be arranged corresponding to the position of the second feeding and discharging module.

[0029] In addition, in the above-mentioned first testing environment to the sixth testing environment, the first testing environment, the second testing environment and the third testing environment are different respectively, and the fourth testing environment, the fifth testing environment and the sixth testing environment are also different respectively; the first testing environment and the fourth testing environment can be the same testing environment, the second testing environment and the fifth testing environment can be the same testing environment, and the third testing environment and the sixth testing environment can be the same testing environment, so that synchronous testing of the two groups of A end and B end can be realized; of course, the above-mentioned first testing environment to the sixth testing environment can all be different respectively, in this case, although the two groups of A end and B end testing can be synchronized, but the testing of the two groups of products in different environments can be realized.

[0030] In one specific embodiment of the present application, the feeding and discharging module includes an automatic feeding module and an automatic discharging module; the automatic feeding module is used for feeding the testing module rotated in place, and the automatic discharging module is used for discharging the optical product tested in all testing environments from the testing module rotated in place.

The specific rotation angle can be set according to the angle between the test modules, and is not limited to the specific example shown in the drawings.

[0033] In the application process of the optical product test device in the embodiment of the application, first, the first test module is loaded by the automatic loading module in the first up-down loading module, and the fourth test module is loaded by the automatic loading module in the second up-down loading module, and then the products in the first test module are tested in the test environment 11, and the products in the fourth test module are tested in the test environment 21.

[0034] Then, the rotating support is controlled to rotate counterclockwise by 60°, the products in the first test module are tested in the test environment 12, and the products in the fourth test module are tested in the test environment 22; at the same time, the sixth test module is loaded by the automatic loading module in the first up-down loading module, and the corresponding test is completed in the test environment 11, and the third test module is loaded by the automatic loading module in the second up-down loading module, and the corresponding test is completed in the test environment 21.

[0035] Then, the rotating support is controlled to rotate counterclockwise by 60°, the products in the first test module are tested in the test environment 12, and the products in the fourth test module are tested in the test environment 22; at the same time, the sixth test module is loaded by the automatic loading module in the first up-down loading module, and the corresponding test is completed in the test environment 11, and the third test module is loaded by the automatic loading module in the second up-down loading module, and the corresponding test is completed in the test environment 21.

[0036] Finally, the rotating support is controlled to rotate clockwise by 120° to return to the initial test position, and the products in the first test module after the test under three environments are unloaded by the automatic unloading module in the first up-and-down feeding module, and the products in the fourth test module after the test under three environments are unloaded by the automatic unloading module in the second up-and-down feeding module.

[0037] The above-mentioned actions are repeatedly performed, so that the synchronous test under multiple products and multiple environments can be realized, the test efficiency can be improved, different types of optical products can be tested by changing or replacing the external test environment, the flexibility is high, and the application range is wide.

[0038] In addition, as Figure 4 shown in another specific embodiment of the present application, the optical product test device further comprises a control unit 4, a transmission unit 5 and a test board card 6 connected in sequence; wherein the test modules in the optical product test device 100 are connected and conducted with the test board card 6 through various ways such as 12C or SPI serial external interface, the control unit 4 such as PC can control the test board card 6 to detect the optical products to be tested in the test module through the transmission unit 5 such as can bus.

[0039] It should be noted that the shape of the rotating support can be circular or regular polygon, and the rotating support is provided with a wiring hole in the inside, and the test modules are uniformly distributed on the rotating support, for example, a regular hexagon shown in the drawing, it can be known that the number of test modules, the number of test environments and the number of test ends (A end and B end) in the embodiment of the present application can be adjusted according to the specific application scene, for example, three test ends, two different test environments (three groups are set) and six test modules can be set, and the structure can realize the synchronous test of three groups of products under two different test environments.

[0040] As a specific example, Figure 5 a schematic state of the optical product test device according to the embodiment of the present application under different rotating positions is shown.

[0041] As Figure 5 shown in this embodiment, P1, P2 and P3 respectively represent different test modules arranged on the rotating support, and the whole device has two groups of test modules P1 to P3, in the application process, each test module can be folded outward relative to the rotating support, so as to facilitate the up-and-down feeding and detection of each test module.

[0042] In the initial position shown in state 1, optical products to be tested are pre-positioned in both P2 and P3 by default. At this point, P1 can be loaded, and testing can be completed in test environment 1. After P1, P2, and P3 have all completed their corresponding tests, the rotating bracket is rotated 60° counterclockwise. The device is now in state 2. P2 moves to the loading position to load and unload (unload the tested products and then reload the untested products), and tests in environment 1 are performed. Simultaneously, P1 moves to the test environment 2 position to perform tests in test environment 2. After P1, P2, and P3 have all completed their corresponding tests, the rotating bracket is rotated 60° counterclockwise again. The device is now in state 3. P3 moves to the loading position to load and unload, and tests in test environment 1 are completed. Simultaneously, P2 moves to the test environment 2 position to perform tests, and P1 moves to the test environment 3 position to perform tests.

[0043] Finally, after P1, P2 and P3 have completed their respective tests, rotate the rotating bracket 120° clockwise. At this time, the device is in state 4. First, unload the material at position P1, then load the material and perform the test under test environment 1. At this time, P2 moves to position 3 for testing; P3 moves to position 2 for testing, and the above steps are repeated.
