Description

Technical Field

[0001] The utility model relates to camera module testing equipment, in particular to glare testing equipment. Background Art

[0002] When strong light strikes the surface of a camera module lens, some light is inevitably reflected. This reflected light bounces multiple times within the lens and camera structure, causing the so-called "glare" phenomenon. To ensure the quality of camera modules, glare testing is often necessary. This involves rotating the camera module and photographing a strong point light source at different angles under a dark screen. The captured images are then analyzed to determine whether the lens produces "glare" when strong light enters the lens.

[0003] Most existing glare testing equipment uses manually rotated camera modules, which is inefficient during testing. Manual operation easily misses some angles and cannot guarantee that images of all angles required for testing are captured. In addition, existing glare testing equipment cannot provide a dark environment by itself and needs to be placed in a dark room. A lighting lamp is installed on the frame of the glare testing equipment. The lighting lamp is turned off during the test and turned on when loading and unloading materials. Utility Model Content

[0033] The first axis is along the left-right direction, and the second axis is along the front-back direction. The first driving element 2024 and the second driving element 2025 are both motors. The first driving element 2024 and the second driving element 2025 drive the camera module to rotate along the first and second axes, and capture the strong point light source emitted by the point light source transmitting box 2011 from different angles. The captured images can be used to analyze the glare effect of the camera module, which is used to detect whether the lens will produce "glare" when strong light enters the lens. There is no need for manual angle adjustment, which is highly efficient. In addition, the motor drive will not miss some angles, and can ensure that images of the required angles for the test are all captured.

[0034] In this embodiment, a first cavity is provided inside the frame body 1, and the first cavity has an inlet and outlet 101. The frame body 1 is provided with a lifting light-shielding roller curtain 102 at a position corresponding to the inlet and outlet 101; the lifting light-shielding roller curtain 102 can open or close the inlet and outlet 101, so that the first cavity is connected to the outside or the first cavity forms a closed chamber structure.

[0035] By raising and lowering the light-shielding roller shutter 102 to open the inlet and outlet port 101, the first cavity can be connected to the outside. At this time, the camera module can feed or discharge materials into or out of the first cavity through the inlet and outlet port 101; by raising and lowering the light-shielding roller shutter 102 to close the inlet and outlet port 101, the first cavity can form a closed chamber structure. At this time, external light cannot enter the first cavity, and the interior of the first cavity becomes a dark environment, thereby providing a dark environment for the glare test component 2 through the frame main body 1.

[0036] In this embodiment, the rotating jig 202 is arranged in the first cavity; the lifting light source component 201 includes a point light source emission box 2011 and an adjustment mechanism for driving the point light source emission box 2011 to rise and fall, and the point light source emission box 2011 extends into the first cavity and can emit light source toward the rotating jig 202.

[0037] In this embodiment, the adjustment mechanism includes a fourth mounting bracket 2012, a guide rod 2013, a screw 2014, a handle 2015 and a nut seat 2016. The guide rod 2013 is fixedly mounted on the fourth mounting bracket 2012, and the screw 2014 is rotatably mounted on the fourth mounting bracket 2012. The axes of the guide rod 2013 and the screw 2014 are both in the up and down directions. The handle 2015 is connected to the screw 2014, the nut seat 2016 is threadedly engaged with the screw 2014, and the nut seat 2016 is slidingly engaged with the guide rod 2013.

[0038] In this embodiment, the frame body 1 is enclosed by an upper side panel 103, a lower side panel 104, a left side panel 105, a right side panel 106, a front side panel 107 and a rear side panel 108 to form the first cavity. The material inlet and outlet 101 and the lifting shading roller shutter 102 are both arranged on the front side panel 107. The rotating fixture 202 is connected to the lower side panel 104, and the lifting light source component 201 is connected to the upper side panel 103.

[0039] In this embodiment, the rack body 1 further includes a plurality of shielding plates 109 disposed above the upper side plate 103 , and a second cavity is formed between the upper side plate 103 and the plurality of shielding plates 109 .

[0040] The point light source transmitting box 2011 is fixedly connected to the nut seat 2016, and a through hole that conforms to the point light source transmitting box 2011 is provided on the upper side plate 103. The upper part of the point light source transmitting box 2011 is located above the upper side plate 103, and the lower part of the point light source transmitting box 2011 passes through the through hole and extends into the first cavity. In order to ensure that the black screen environment is lightless, a plurality of mask plates 109 can also be provided above the upper side plate 103. The upper side plate 103 and the plurality of mask plates 109 enclose a second cavity, and one of the mask plates 109 is provided in an openable and closable form. When testing the camera modules of the same batch, after the height position of the point light source transmitting box 2011 is adjusted by the adjustment mechanism, it is generally not changed, so manual adjustment is adopted.

[0041] In this embodiment, the lifting and lowering light-blocking roller blind 102 includes a roller blind drive element 1021, a roller blind transmission assembly 1022, a roller blind shaft 1023, a light-blocking roller blind cloth 1024, a slide rod 1025 and two roller blind guide rails 1026. The roller blind drive element 1021 drives the roller blind shaft 1023 to rotate through the roller blind transmission assembly 1022. The roller blind shaft 1023 is arranged on the upper side of the inlet and outlet 101. The two roller blind guide rails 1026 are respectively located on the left and right sides of the inlet and outlet 101. The head and tail ends of the light-blocking roller blind cloth 1024 are respectively connected to the roller blind shaft 1023 and the slide rod 1025, and the light-blocking roller blind cloth 1024 is rolled up on the roller blind shaft 1023. The left and right sides of the slide rod 1025 are respectively slidably matched with the two roller blind guide rails 1026.

[0042] The roller blind drive element 1021 is a motor. The motor's output shaft drives the roller blind shaft 1023 in forward or reverse rotation through the roller blind transmission assembly 1022, thereby retracting or unretracting the shade roller blind 1024. The left and right sides of the slide rod 1025 slide into the slide grooves of the roller blind guide rail 1026. After the shade roller blind 1024 is retracted onto the roller blind shaft 1023, it no longer blocks the inlet and outlet 101. The slide rod 1025 also moves with the shade roller blind 1024 above the inlet and outlet 101, thereby raising and lowering the shade roller blind 102 and opening the inlet and outlet 101. After the shade roller blind 1024 is unrolled, the slide rod 1025 slides downward along the roller blind guide rail 1026 due to gravity. This movement of the slide rod 1025 simultaneously drives the shade roller blind 1024, thereby raising and lowering the shade roller blind 102 and closing the inlet and outlet 101.

[0043] In this embodiment, the lifting light-blocking roller blind 102 further includes two fixing seats 1027 , both of which are located above the material inlet and outlet 101 , and the left and right sides of the roller blind shaft 1023 are respectively rotatably engaged with the two fixing seats 1027 .

[0044] In this embodiment, the roller blind drive assembly 1022 includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is fixedly connected to the output shaft of the roller blind drive element 1021, the driven pulley is fixedly connected to one end of the roller blind shaft 1023, and the transmission belt is externally mounted on the driving and driven pulleys. The driving pulley, driven pulley, and transmission belt form a belt drive kinematic pair, which can further simplify the structure of the dark curtain environment test rack and reduce manufacturing, installation, and maintenance costs.

[0045] In this embodiment, the lifting shading roller blind 102 also includes a limiting pressure rod 1028 and a lower limiting member 1029; the limiting pressure rod 1028 is arranged between the roller blind shaft 1023 and the roller blind guide rail 1026, and a gap is formed between the limiting pressure rod 1028 and the front side panel 107, and the shading roller blind fabric 1024 passes through the gap; the lower limiting member 1029 is located below the inlet and outlet 101.

[0046] The limiting pressure rod 1028 is a cylindrical rod. The shade roller blind 1024 is preferably inserted into the sliding groove of the roller blind guide 1026 in a sliding fit. The limiting pressure rod 1028 constrains the position and direction of the shade roller blind 1024, preventing friction damage between the shade roller blind 1024 and the sliding groove of the roller blind guide 1026. When the slide bar 1025 abuts the lower limiting member 1029, it indicates that the slide bar 1025 has moved into position and completely closes the inlet and outlet 101. The lower limiting member 1029 also blocks the gap between the slide bar 1025 and the inlet and outlet 101, preventing light from entering the first cavity between the inlet and outlet 101 and the slide bar 1025. Position sensors 110 can be provided on both sides of the lower limiting member 1029 to detect whether the slide bar 1025 has moved into position.

[0047] During the glare test, after opening the inlet and outlet 101 and securing the camera module to the module positioning seat 2026, the inlet and outlet 101 is closed by raising and lowering the light-blocking roller shutter 102, forming a closed chamber structure in the first cavity. At this point, external light cannot enter the first cavity, and the interior of the first cavity becomes a dark environment. Then, the first and second drive elements 2024 and 2025 drive the camera module to rotate about the first and second axes, capturing the strong point light source emitted by the point light source emission box 2011 from different angles. The captured images can be analyzed to obtain the glare effect of the camera module, which is used to detect whether the lens will produce "glare" when strong light enters the lens. After the test is completed, the inlet and outlet 101 is opened to remove the camera module and place the next camera module to be tested.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
