DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0023] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides a test device for an image sensor, including a test base plate 1: A support frame 2 is fixedly connected above the test base plate 1, and a plurality of light source test components are fixedly connected to the top of the support frame 2; The light source test component includes an electric lifting rod 3 fixedly connected to the top of the support frame 2, the output end of the electric lifting rod 3 is fixedly connected with a mounting frame body 4, both side walls of the mounting frame body 4 are threadedly connected through adjusting screws 5, the end of the adjusting screw 5 located outside the mounting frame body 4 is fixedly connected with a knob 14, and the ends of both adjusting screws 5 located inside the mounting frame body 4 are rotatably connected with arc-shaped clamping plates 6. An arc-shaped silica gel gasket is fixedly connected to the inner surface of the arc-shaped clamping plate 6, and a limiting component is fixedly connected to the arc-shaped clamping plate 6. The limiting component includes a limiting rod 10 fixedly connected to the arc-shaped clamping plate 6, and a plurality of limiting through holes are provided on the side wall of the mounting frame body 4, and the limiting rod 10 is matched with the limiting through holes;

[0024] By rotating the knob 14 to drive the rotation of the adjusting screw 5, the adjusting screw 5 rotates relative to the arc-shaped clamping plate 6 and pushes the arc-shaped clamping plate 6, so that the arc-shaped clamping plate 6 tightly fixes the outer wall of the LED lamp 15. Thus, a plurality of LED lamps 15 with different luminous specifications can be installed in a plurality of mounting frame bodies 4 to avoid frequent replacement operations of the LED lamps 15. At the same time, the inside of the mounting frame body 4 can support the installation of LED lamps 15 with different luminous specifications through the tight fixing of the arc-shaped clamping plate 6, thereby improving the test applicability of the test device.

[0025] As Figure 1 and Figure 3 shown, a position adjusting component is fixedly connected above the test base plate 1. The position adjusting component includes a slide rail base 7 fixedly connected above the test base plate 1, a position adjusting plate 8 is slidably connected to the top of the slide rail base 7, a sensor base 9 is fixedly connected to the middle of the position adjusting plate 8, and an adjusting driving component is rotatably connected through the side wall of the slide rail base 7. The adjusting driving component includes a rotating shaft rotatably connected through the side wall of the slide rail base 7, two gears 11 are fixedly connected to the rotating shaft, two rack plates 12 are fixedly connected to the bottom of the position adjusting plate 8, the teeth on the two gears 11 are respectively meshed with the racks on the two rack plates 12, and a driving motor 13 is fixedly connected above the test base plate 1, and the output end of the driving motor 13 is fixedly connected to one end of the rotating shaft;

[0026] The rotating shaft is driven by the drive motor 13 to rotate, causing the two gears 11 on the rotating shaft to start rotating. The adjustment plate 8 is driven to move through the meshing transmission between the two gears 11 and the racks on the two rack plates 12, so that the sensor base 9 and the image sensor on the adjustment plate 8 can be moved directly below the target test LED lamp 15. By supporting the position adjustment of the image sensor and using multiple LED lamps 15 with different luminous specifications to cooperate with the image sensor for light source testing, the test work efficiency of the image sensor can be effectively improved.

[0027] The detailed working process of the present utility model is as follows:

[0028] 1. When the image sensor testing device is in use, multiple groups of LED lamps 15, that is, LED lamps 15 with different luminous specifications, are correspondingly placed in the mounting frame body 4. The adjusting screw 5 is driven to rotate by rotating the knob 14, so that the adjusting screw 5 rotates relative to the arc-shaped clamping plate 6 and pushes the arc-shaped clamping plate 6, thereby making the arc-shaped clamping plate 6 tightly fit against the outer wall of the LED lamp 15, and thus multiple LED lamps 15 with different luminous specifications can be installed in several mounting frame bodies 4 to avoid frequent replacement operations of the LED lamps 15. At the same time, the inside of the mounting frame body 4 can support the installation of LED lamps 15 with different luminous specifications through the tight fit of the arc-shaped clamping plate 6, thereby improving the test applicability of the testing device.

[0029] 2. After multiple groups of LED lamps 15 are installed and fixed, the image sensor is installed in the sensor base 9. If it is necessary to adjust the position of the image sensor below the LED lamp 15 with the luminous specification to be tested, the drive motor 13 can be controlled to start. The rotating shaft is driven by the drive motor 13 to rotate, causing the two gears 11 on the rotating shaft to start rotating. The adjustment plate 8 is driven to move through the meshing transmission between the two gears 11 and the racks on the two rack plates 12, so that the sensor base 9 and the image sensor on the adjustment plate 8 can be moved directly below the target test LED lamp 15. By supporting the position adjustment of the image sensor and using multiple LED lamps 15 with different luminous specifications to conduct light source testing on the image sensor, the test work efficiency of the image sensor can be effectively improved.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them.
