Description

Technical Field

[0001] This utility model belongs to the field of mobile phone camera testing technology, and more specifically, it relates to a mobile phone camera anti-shake testing device. Background Technology

[0002] With the development of smartphones, mobile phones have become more than just communication devices. More and more people enjoy using them to take photos and videos to capture precious moments, thus placing increasing emphasis on image quality. As mobile phone cameras rapidly advance towards higher resolutions and multi-directional shooting capabilities, more and more users are choosing their phones as their primary image capture tool. Among these users are photography enthusiasts and even professionals who have higher demands for mobile phone images, one of which is image stabilization.

[0003] During the mobile phone manufacturing process, the optical image stabilization (OIS) function of the phone camera needs to be tested. This test mainly involves the calibration and inspection of camera components at the factory. However, this method only tests the OIS function of the camera components and does not test the OIS when the camera is installed on the phone. If the position of the camera deviates during installation, it may affect the OIS function. To conduct double verification, testers use handheld shooting to test the OIS after the phones are manufactured. However, it is impossible to guarantee that the degree of shaking is the same for every device during testing, and the testing efficiency is low, resulting in insufficient accuracy and failing to meet the needs of the general public.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mobile phone camera image stabilization testing device in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] This utility model provides a mobile phone camera anti-shake testing device, including a workbench 1 and a test cabinet 2 covered on top of it. A vibration machine table 3 is provided on one side of the bottom of the test cabinet 2. A vibration seat 4 is provided on the vibration machine table 3. A support frame 5 is connected to the top of the vibration seat 4. A clamping assembly 6 is provided on one side of the support frame 5. The clamping assembly 6 includes a positioning block 61 connected to one side of the support frame 5. A miniature double-headed cylinder 62 is embedded inside the positioning block 61. Both piston rod ends of the miniature double-headed cylinder 62 are connected to L-shaped clamping arms 63. The mobile phone body 7 is clamped between the two L-shaped clamping arms 63. A rotating assembly 8 is provided on the other side of the support frame 5 to drive the mobile phone body 7 and the clamping assembly 6 to rotate. A test plate 9 is provided on one side of the inner wall of the test cabinet 2. A test block 10 is installed on one side of the test plate 9.

[0029] In other embodiments, a plurality of rubber sheets 65 are evenly distributed on the surface of the positioning block 61. The rubber sheets 65 are attached to the rear side of the mobile phone body 7. Two L-shaped clamping arms 63 are each connected to a silicone block 64 on their opposite sides. The two silicone blocks 64 are attached to both sides of the mobile phone body 7. The mobile phone body 7 is placed on the surface of the positioning block 61. The micro double-headed cylinder 62 is activated. The two piston rods of the micro double-headed cylinder 62 extend, thereby driving the two L-shaped clamping arms 63 to position and clamp the mobile phone body 7 to prevent the mobile phone body 7 from shifting or loosening during vibration testing. This ensures the reliability of the relative position of the mobile phone body 7. The rubber sheets 65 and silicone blocks 64 protect the mobile phone body 7 and prevent the positioning block 61 and the two L-shaped clamping arms 63 from damaging the mobile phone body 7.

[0030] In other embodiments, the rotating component 8 includes a protective box 81, which is fixedly connected to the other side of the support frame 5. A micro motor 82 is installed inside the protective box 81. The micro motor 82 is a stepper micro motor, which can drive the main body of the mobile phone 7 to rotate 45°, 90° and 180°, thereby testing the anti-shake effect at different angles. This can achieve the test effect of simulating the real machine and improve the accuracy of the test.

[0031] In other embodiments, the output shaft of the micro motor 82 is connected to a rotating shaft 83. One end of the rotating shaft 83 passes through the support frame 5 and is fixedly connected to one side of the positioning block 61. When the micro motor 82 is started, the micro motor 82 can drive the rotating shaft 83 to rotate, thereby driving the positioning block 61 and the mobile phone body 7 on it to rotate, so that the mobile phone body 7 is in different angles for shooting.

[0032] In other embodiments, the front of the test cabinet 2 is hinged with two cabinet doors 13, and multiple spotlights 11 are installed on the top of the test cabinet 2. The multiple spotlights 11 are all tilted above the test block 10. The multiple spotlights 11 illuminate the test block 10, improve the clarity of the test block 10 captured by the mobile phone 7, and improve the test effect.

[0033] In other embodiments, a PLC controller 15 is connected to the top side of the workbench 1 via a bent rod 12. The PLC controller 15 is electrically connected to the vibration machine 3, the miniature double-headed cylinder 62, the mobile phone body 7, the miniature motor 82, and the spotlight 11. The PLC controller 15 controls the operation of the vibration machine 3, the miniature double-headed cylinder 62, the mobile phone body 7, the miniature motor 82, and the spotlight 11, making the camera stabilization test more intelligent.

[0034] In other embodiments, four support legs 14 are fixedly installed at the bottom corners of the workbench 1 to support and fix the workbench 1, ensuring its stable placement.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, the two cabinet doors 13 are opened, and the mobile phone body 7 is placed against the surface of the positioning block 61. The miniature double-headed cylinder 62 is activated, and the two piston rods of the miniature double-headed cylinder 62 extend, thereby driving the two L-shaped clamping arms 63 to move closer together, positioning and clamping the mobile phone body 7 to prevent displacement or loosening during vibration testing, ensuring the reliability of the relative position of the mobile phone body 7. At this time, the camera of the mobile phone body 7 is facing the test block 10, and the mobile phone body 7 is in a vertical position. The PLC controller 15 controls the vibration table 3 to work. When the vibration table 3 is working, the vibration seat 4 transmits the vibration to the support. The support frame 5 causes the support frame 5 and the mobile phone body 7 on it to vibrate with the vibration seat 4. The PLC controller 15 controls the mobile phone body 7 to take test images of the test block 10 with the anti-shake function enabled, and obtains the first test image. Then, the PLC controller 15 controls the micro motor 82 to start. The stepper micro motor can drive the mobile phone body 7 to rotate 45°, 90° and 180° in sequence. The mobile phone body 7 at different angles takes test images of the test block 10 with the anti-shake function enabled, and obtains the second test image, the third test image and the fourth test image.

[0037] When the vibration table 3 stops working, the camera of the mobile phone body 7 faces the test block 10, and the mobile phone body 7 is in a vertical position. The PLC controller 15 controls the mobile phone body 7 to take test images of the test block 10 with the image stabilization function turned off, obtaining the fifth test image. Then, the PLC controller 15 controls the micro motor 82 to start. The stepper micro motor can drive the mobile phone body 7 to rotate 45°, 90° and 180° in sequence. At different angles, the mobile phone body 7 takes test images of the test block 10 with the image stabilization function turned off, obtaining the sixth, seventh and eighth test images. Finally, the first, second, third and fourth test images are compared with the fifth, sixth, seventh and eighth test images to determine the camera image stabilization performance value of the mobile phone under test, so as to better and more comprehensively achieve the test effect of simulating the real machine.

[0038] It should be noted that the specific models and specifications of the PLC controller 15, vibrating machine table 3, miniature double-headed cylinder 62, mobile phone body 7, miniature motor 82, and spotlight 11 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail. The PLC controller 15, vibrating machine table 3, miniature double-headed cylinder 62, mobile phone body 7, miniature motor 82, and spotlight 11 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition, and principle are clear to those skilled in the art and are common knowledge in this field, so they will not be described in detail.
