Problems solved by technology

[0006] In order to make up for the shortcomings of the existing technology, the detection device needs an external light source to provide detection light, which is inconvenient to use, and it is difficult to ensure the coincidence between the detection light and the axis of the camera module. At the same time, it is necessary to adjust the angle of the detection light. It is difficult to determine the angle between the detection light and the axis of the camera module, which has a certain impact on the detection results and accuracy. The invention proposes a mobile phone photosensitive element detection device and detection method

Embodiment 1

[0039] See Figure 1-8 It shows, a mobile phone sensor detection device, including base 1, stent 2 and workbench 3. The upper side of the workbench 3 is equipped with a packet 4, and the installation is connected to the computer electrical; the installation is installed; There is a contact block 5 on the upper side of the Tower 4 through the support frame; the stent 2 above the packet 4 is connected to the hydraulic cylinder 6 in the bracket 2; 7 The lower end is linked to the light source transmitter 8; at work, the detection device in the existing technology requires external light sources to provide detection light. It is not convenient to use, and it is difficult to ensure the weight between the detection light and the camera module axis. At the same time, at the same time When you need to adjust the angle of the detection of light, it is difficult to determine the angle between the detection light and the camera module axis, which has a certain effect on the results and accura...

Embodiment 2

[0053] See Figure 9 The comparison embodiments one, the other embodiment of the driver's institution is to converge with the central axis of the stamping cylinder 15 and the central axis of the air pressure cylinder 15; at work, by working, by the mobile phone, by the mobile phone, the mobile phone is by working. The camera module is taken out. In a full black environment, the camera module is placed on the installation of the detection device to clamp the table 4, clamp the camera module by the contact block 5, and at the same time start the light source transmitter 8, through the hydraulic cylinder 6 6, 6 Adjust the distance between the light source transmitter 8 and the camera module, when the angle between the detection of the axis between the light and the camera module needs to be adjusted, the sliding strip 13 is slid in the slide 12 through the stress cylinder 15, and then connects the number of slides, and then connects to connect, and then connects to connect. Ring 14 dr...

Embodiment 3

[0055] See Figure 10 The comparison of embodiment 1, as another embodiment of the present invention, the position of the sliding rod 19 and the No. 2 slide 18 contact is connected to the No. 2 roller wheel 65; at work, the No. 2 roller wheel 65 is 65 of the 65 roller wheel 65. Settings can reduce the friction of the sliding rod 19 and No. 2 slide 18, and reduce the amount of wear.

[0056] When working, take out the camera module in the mobile phone. In a full black environment, the camera module is placed on the installation of the detection device on the packet 4, and the camera module is tightened by the contact block 5. 8. Adjust the distance between the light source transmitter 8 and the camera module through the hydraulic cylinder 6. When the distance is appropriate, read the number of light sensing points on the sensor of the camera module through the computer. In the test, this test device comes with a light source transmitter 8, which does not need to be added with light ...

Abstract

The invention belongs to the technical field of communication, in particular to a mobile phone photosensitive element detection device, comprising a base, a bracket and a worktable, a clamping table is arranged on the upper side of the worktable; a contact block is fixedly connected to the upper side of the clamping table through a support frame A hydraulic cylinder is fixedly connected to the bracket above the clamping table, and a light source transmitter is fixedly connected to the lower end of the hydraulic rod; a mobile phone photosensitive element detection method, including S1: placing a camera module on the clamping table, clamping the camera Module; S2: Start the light source transmitter, adjust the distance, and read the digital quantity converted by each photosensitive point; S3: Start the motor, adjust the inclination angle of the clamping table, and read the digital quantity converted by each photosensitive point; S4: Analysis result And compare with the preset threshold to judge whether the photosensitive quality of the camera module is qualified; the test device in the present invention has its own light source emitter, which can ensure the coincidence between the detection light and the axis of the camera module, and improve the detection result. accuracy.

Description

Technical field [0001] The invention is a communication technology field. Specifically, it is a mobile phone sensing component detection device and detection method. Background technique [0002] There are two main factors that affect the quality of the image during the camera process of the smart terminal: one is the difference in the camera module of the smart terminal itself, and the other is the difference between the post -processing of the data collected by the camera module in the later stage, and the difference between the camera module. It is mainly reflected in the quality of the camera module. [0003] There are also some technical solutions about detection of photosensitive elements in existing technologies. For example, a Chinese patent with the application number 2015110165895 discloses a test method and device of the photoresmal sensitivity, including: when the surface of the camera module is received, it is received. When detecting the light, read the number of th...
