The present invention provides a multifunctional image test light box to solve the problems in the prior art that the wide-angle test light box occupies a large area, is inconvenient to move, and cannot meet the angle requirements of FOV of different products.

For ease of understanding, the specific process in the embodiment of the present application is described below, please refer to Figures 1 to 3. A multifunctional image test light box in the embodiment of the present application includes a frame 1, a carrying platform 2, a fixture placement area 3, a flat light source panel 4, an arc bracket 5 and a parallel light tube 6; the carrying platform 2 is installed in the middle of the frame 1, thereby dividing the interior of the frame 1 into two layers, the lower layer can be used to place a computer host, a product to be tested, etc., and the upper layer is used to install the fixture placement area 3, the flat light source panel 4, the arc bracket 5 and the parallel light tube 6, etc.

Based on FIG. 2 , the fixture placement area 3 is disposed at the center of the upper surface of the carrying platform 2 for placing a fixture carrying a product so that related tests can be performed on the product later.

Based on Figures 1 and 2, the planar light source panel 4 is arranged in the frame 1 in a liftable manner and is located above the jig placement area 3. The planar light source panel 4 is arranged parallel to the jig placement area 3. The height of the planar light source panel 4 and the product in the jig placement area 3 is adjusted in real time by lifting and lowering the planar light source panel 4 to meet the needs of different products and scenes. The purpose of the planar light source panel 4 is to provide a light source environment in the center of the product.

Specifically, the lower ends of the planar light source panel 4 are connected to two connecting rods 40 on both sides; the two connecting rods 40 are connected to two adjusting screws 41 located on the bearing table 2; the four corners of the bearing table 2 are also provided with four guide columns 42 that are arranged through, and the four guide columns 42 are vertically installed inside the frame 1; the planar light source panel 4 can be slid up and down in the guide columns 42. During operation, the two adjusting screws 41 synchronously drive the planar light source 4 to rise and fall directly above the fixture placement area 3 through the corresponding connecting rods 40 under the guidance of the guide columns 42, thereby meeting the requirements of different products for the light source height, and the practicability is strong. In addition, for ease of use, an adjustment button for controlling the adjustment screw 41 is also installed on the outside of the frame 1.

Based on Figure 2, this embodiment includes four arc-shaped brackets 5, and each of the four arc-shaped brackets 5 is provided with two relatively arranged parallel light tubes 6. Of course, there can be more than two parallel light tubes 6, which can be adjusted according to actual needs. The four arc-shaped brackets 5 are just arranged around the fixture placement area 3.

Secondly, in order to provide a variety of module image display ratios for the product, the angle of the arc bracket 5 needs to be adjusted, so a mounting plate 20 is set below the bearing table 2; the mounting plate 20 is provided with a rotating motor 21, and the rotating motor 21 drives the rotating disk 22 located on the bearing table 2 to rotate, and the arc bracket 5 is set on the rotating disk 22 and rotates with the rotating disk 22. According to this, the arc bracket 5 can be rotated and adjusted in angle by the rotating motor 21, and according to the requirements of the module image display ratio of 1:1, 4:3, and 16:9, the arc bracket 5 can be rotated to the corresponding position by the rotating motor 21, which greatly improves the adaptability and convenience of the test light box.

Based on Figures 2 and 3, in this embodiment, the collimator 6 is adjustably disposed on the arc bracket 5 to emit a parallel light beam to the product located in the fixture placement area 3. The four collimator light tubes can provide a test optical environment around the product.

In addition, the collimator 6 is detachably mounted on the arc bracket 5 through a quick-release assembly, and the collimator 6 points to the fixture placement area 3. The quick-release assembly in this embodiment includes an L-shaped first mounting block 61 and a second mounting block 62. The first mounting block 61 and the second mounting block 62 can be mounted at any position of the arc bracket 5 through a locking buckle 63, and the collimator 6 is arranged on the lower surface of the first mounting block 61 and the second mounting block 62, so that the collimator 6 can be installed at different positions of the arc bracket 5, and the position of the collimator 6 can be adjusted at multiple angles by adjusting the angle of the arc bracket 5, that is, different angles meet the requirements of different FOV products: if the FOV is 120°, 150°, this test light box is compatible with the test requirements of different FOV products at angles of 20° to 220°.

The arc bracket 5 in this test light box cooperates with the light source of the planar light source board 4, which can be compatible with the test requirements of product FOV between 20° and 220°. When the product FOV is between 20° and 80°, the planar light source board 4 is used; when the product FOV is between 80° and 220°, the planar light source board and the parallel light tube are used at the same time, with good versatility.

Furthermore, a teleconverter bracket 7 is provided on one side of the carrying platform 2 for placing a teleconverter so as to meet the requirement of testing modules with a longer distance.

Furthermore, a spherical light source plate 8 is provided on the right side of the jig placement area 3. The spherical light source plate 8 can be telescopically set on one side of the jig placement area 3 via a driving cylinder 10, and a spherical light source is arranged on the spherical light source plate 8; when a spherical light source is required for testing the OC, the driving cylinder 10 can push out the spherical light source plate 8.

Furthermore, a pulley 9 is provided at the bottom of the frame 1, so that the test light box can be conveniently moved, the operation is convenient and labor-saving, and the use requirements are met.

The specific work process is as follows:

First, place the product on the jig, and then place the jig together with the product in the jig placement area 3. When the distance needs to be increased, press the control button of the teleconverter, push the teleconverter above the product lens, and then adjust the height of the flat light source board 4 by adjusting the screw 41 to meet the optical environment requirements of different products for the center point.

Then, according to the requirements of the image display ratio of the photo module, four arc brackets 5 are installed on the rotatable platform. At the same time, according to the angle requirements of the FOV of different products, the quick-release assembly is installed to the corresponding position of the arc bracket 5, and then the collimator 6 is installed on the arc bracket. Two collimators are installed on each arc bracket, so that the test angle requirements of the FOV of different products can be achieved, and the requirements of testing two fields of view at the same time can also be met. The test light box can perform field of view tests on different products in various wide-angle lenses (FOV is between 20°-220°) to observe whether the product has black spots, dirt and other defects, which meets the actual use requirements.

As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
