Description

Technical Field

[0001] This utility model belongs to the field of imaging module testing technology, and in particular relates to an imaging module testing platform. Background Technology

[0002] With the rapid development of smartphones, autonomous driving, security monitoring, and AR / VR devices, the performance requirements for imaging modules (such as cameras and optical sensors) are increasing. Imaging modules need to meet stringent standards in many aspects, including resolution, focusing accuracy, color reproduction, and low-light performance, making the testing phase a critical part of the production process.

[0003] Currently, traditional imaging module testing platforms typically use manual or semi-automatic methods to test imaging modules, relying on manual adjustment of module positions and parameters. This makes it difficult to meet the large-scale testing needs of imaging modules. Furthermore, existing testing platforms can usually only test imaging modules of a single specification, resulting in poor versatility and making it difficult to test imaging modules of multiple specifications.

[0026] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0027] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] This embodiment provides an imaging module testing platform that enables rapid testing of imaging modules without the need for manual adjustments, ensuring testing accuracy and meeting the needs of large-scale testing of imaging modules.

[0029] Combination Figures 1 to 3 As shown, the imaging module test platform of this embodiment includes a platform body 10, a lifting part 20, a test lens 30, an image plate 40, and a display panel 50. The image plate 40 of this embodiment has an image or video. The test lens 30 is aligned with the image plate 40 to obtain the imaging light and shadow, and then the imaging module obtains the imaging light and shadow of the test lens 30. The test fixture 11 is connected to the display panel 50 through a video signal cable to output the imaging light and shadow to the display panel 50, thereby testing whether the imaging module is working properly.

[0030] In this embodiment, a test fixture 11 is provided on the platform body 10. Multiple sets of lifting units 20 are distributed along the length of the test fixture 11. The test lens 30 is driven by the lifting units 20 to move closer to or away from the platform body 10. The number of image plates 40 is the same as that of the lifting units 20 and they correspond one-to-one. The image plates 40 and the test lenses 30 are arranged opposite to each other. The display panel 50 is provided on the platform body 10 and connected to the test lenses 30. In this embodiment, the image plates 40 are installed on the test fixture 11. The lifting units 20 drive the test lenses 30 to move closer to the image plates 40. The test lenses 30 are aligned with the image plates 40 to obtain the imaging light and shadow. Then, the imaging module obtains the imaging light and shadow of the test lenses 30 and transmits the imaging light and shadow to the display panel 50 for display to complete the testing process of the imaging module.

[0031] In this embodiment, the platform body 10 is provided with a number of control buttons 60. The control buttons 60 control the lifting part 20. In this embodiment, there are two control buttons 60. When the two control buttons 60 are pressed at the same time, the lifting part 20 works. In this embodiment, the number of lifting parts 20, image plate 40 and display panel 50 are the same and they correspond one-to-one. Therefore, multiple imaging modules can be tested simultaneously, improving testing efficiency and meeting the large-scale testing needs of imaging modules.

[0032] Combination Figure 1 and Figure 3 As shown, the lifting unit 20 in this embodiment includes a lifting driver 21 and a lifting plate 22. The lifting driver 21 drives the lifting plate 22 to change the distance between the lifting plate 22 and the test fixture 11. Multiple test lenses 30 are mounted on the lifting plate 22 to bring the test lenses 30 closer to the image plate 40. Several guide rods 80 are provided on the platform body 10 to guide the lifting plate 22. The lifting unit 20 in this embodiment drives the test lenses 30 to bring them closer to the image plate 40 in order to acquire imaging light and shadow, so as to perform subsequent testing and processing on the imaging module. The presence of the guide rods 80 can guide the movement of the lifting plate 22, making the movement of the test lenses 30 more precise and improving the testing accuracy.

[0033] In this embodiment, the lifting unit 20 is connected to the platform body 10 via the bracket 70, and the image plate 40 is mounted on the test fixture 11 via several positioning pins 90.

[0034] In actual use, the imaging module testing platform of this embodiment sets the image plate 40 on the test fixture 11, and the lifting part 20 drives the test lens 30 to approach the image plate 40. The test lens 30 is aligned with the image plate 40 to obtain the imaging light and shadow, and then the imaging module obtains the imaging light and shadow of the test lens 30. The test fixture 11 is connected to the display panel 50 through the video signal cable and outputs the imaging light and shadow to the display panel 50, thereby testing whether the imaging module is working properly.
