[0002] As camera modules are used in various high-end electronic devices, their performance and quality requirements are becoming increasingly stringent. Therefore, after the camera module is manufactured, it is necessary to test the actual module orientation in accordance with the product's application. However, the testing orientation of existing testing devices in module factories is vertically upward, which introduces a certain orientation error, making it unable to meet the increasingly demanding high-quality testing requirements. Therefore, a camera module testing device and its testing system are designed to solve the orientation error problem in current testing devices, while improving its testing accuracy and efficiency. Summary of the Invention

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] like Figure 1 As shown, a camera module inspection device includes: an inspection box 1, a chart 13, a light-emitting plate 14, a slide rail assembly 16, a teleconverter 17, a rotating slide table 19, and a test box 18. The inspection box 1 has a hollow interior. The slide rail assembly 16 is located on the left side inside the inspection box 1, the teleconverter 17 is located on the right side inside the inspection box 1, and the rotating slide table 19 is located at the bottom of the right outer wall of the inspection box 1. The camera module for inspection is installed in the inner cavity of the test box 18, and the test box 18 is placed on top of the rotating slide table 19. It should be noted that when using this device, the operator needs to first initialize the chart using the sensor, obtain the chart 13, attach the chart 13 to the light-emitting plate 14, and adjust the slider on the slide rail assembly 16 to make the fixing frame 15 reach the appropriate position. At this time, the test box 18 is connected to the rotating slide table 19, the camera module is aligned with the center of the teleconverter 17, and the position and focus are adjusted. Then, the device can be controlled by operating a PC for inspection.
[0027] like Figure 1 As shown in one embodiment, a switch door 12 is provided on the left side of the back of the test box 1, and a reinforcing plate 11 is provided on the inner wall of the back of the test box 1 and around the switch door 12. It should be noted that there are only three reinforcing plates 11, located at the top, bottom and left side of the back of the switch door 12, respectively. The switch door 12 is a single door, and its right side is connected to the outer wall of the test box 1 by a hinge.
[0028] like Figure 1 As shown, in one embodiment, the slide rail assembly 16 includes two slide rails and two sliders that slide on the slide rails. The top of each slider is designed with an integrally formed base plate, and a fixing bracket 15 is fixedly connected to the base plate. The slide rails are longitudinally arranged towards the teleconverter 17. It should be noted that the light-emitting plate 14 is also disposed on the base plate, located on the left side of the base plate, while the fixing bracket 15 is located on the right side of the base plate. A certain distance exists between the fixing bracket 15 and the light-emitting plate 14 for placing Chart 13.
[0029] like Figure 1As shown in one embodiment, the side of the fixing frame 15 is concave, and the fixing frame 15 is located on the right side of the light-emitting plate 14. Chart 13 is located in the center between the fixing frame 15 and the light-emitting plate 14.
[0030] 5. The camera module testing device according to claim 1, characterized in that the Chart (13) is an SFR drawing, and the shape and size of the front of the Chart (13) are compatible with the shape and size of the front of the light-emitting plate (14). It should be noted that the testing box 1 is a fully enclosed design, and the light-emitting plate 14 is the only light source in the testing box 1 when testing is performed.
[0031] like Figure 1 As shown, in one embodiment, the teleconverter 17 is disposed in the center of the inner right side wall of the detection box 1. The front of the teleconverter 17 is circular, and the center of the teleconverter 17 is parallel and perpendicular to the center of the chart 13. It should be noted that this design allows the center of the chart 13 to be parallel and perpendicular to the center of the teleconverter 17.
[0032] like Figure 1 As shown, in one embodiment, the width of the front side of the mounting bracket 15 is the same as the length of the front side of the light-emitting panel 14, and the height of the mounting bracket 15 is half the height of the light-emitting panel 14. It should be noted that this design allows the mounting bracket 15 to fix the chart 13 onto the light-emitting panel 14 without occupying too much area of the chart 13, thus not affecting its normal use.
[0033] like Figure 1 As shown in one embodiment, shock-absorbing blocks are provided at all four corners of the bottom of the testing box 1. It should be noted that this design can reduce the impact of external vibrations on the testing box 1 during testing.
[0034] like Figure 1 As shown in one embodiment, the bottom of the rotating slide 19 is provided with a receiving plate, which is located at the bottom center of the right outer wall of the detection box 1. The top of the rotating slide 19 is located at the center of the bottom of the teleconverter 17. It should be noted that the table surface of the rotating slide 19 is provided with connecting pins that connect to the display module in the test box 18, and the bottom of the rotating slide 19 is provided with an image acquisition board, which is provided with a lens connection cable. The image acquisition board is connected to the PC through this cable, so that the detection data can be directly transmitted to the PC for display.
[0035] To achieve the above objectives, a detection system for a camera module detection device is provided, comprising a resolution adjustment module 2, an image acquisition module 3, a data processing module 4, and a data display module 5. The resolution adjustment module 2 is electrically connected to the display module in the test box 18, the image acquisition module 3 is data connected to the display module in the test box 18, the image acquisition module 3 is data connected to the data processing module 4, and the data processing module 4 is data connected to the data display module 5. It should be noted that the resolution adjustment module 2 can operate the resolution of the design module in the test box 18, allowing the detection device to focus and find the clearest point of the camera module after the sensor initializes and outputs the chart 13 (the output is 4K at a resolution of 4096*3072). At this time, the rotating slide 19 will not move and will remain in place. When the sensor switches to 8K mode for initialization (switching to 8K outputs the chart at a resolution of 8192*6144), the clearest point will still be the clearest point after focusing in 4K mode. The chart 13 is then taken and the SFR resolution value is calculated. Therefore, this detection device allows the camera module to focus in 4K mode and calculate the resolution value in 8K mode, thereby saving a lot of time that would otherwise be spent focusing in 8K mode, thus improving its detection efficiency and saving detection time.
[0036] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
