Problems solved by technology

[0003] In order to improve the production efficiency of the camera module, after the automatic assembly of the camera module is completed, the camera module is transferred to the loading and unloading station through the transmission mechanism to continuously detect various performance parameters, such as black spot detection, automatic focusing and white spot detection, etc. If the position of the assembled camera module transported to the loading and unloading station is shifted, and the station for the subsequent inspection operation is pre-set, the positional deviation of the camera module will easily cause errors in the subsequent inspection operation

Embodiment 1

[0033] Turntable camera module inspection system, such as figure 1 and image 3 Shown: including the processing module, launch module, detection module and prompt module located on the loading and unloading station of the turntable 1; the turntable 1 can use the structure in the existing Chinese patent with the publication number of CN108857381A; the signal of the launch module is connected to the processing module, and the signal of the detection module is connected The processing module, the signal of the prompting module is connected to the processing module, and the processing module can use the SOC chip of existing HiSilicon; There is a single-chip microcomputer with a C8051F120 signal, the control unit signal is connected to the laser unit 7, and the laser unit 7 can use an existing miniature infrared emission tube. Unit 7 is located on the loading and unloading station of the turntable 1 below the camera module 8; the detection module includes a camera unit 6, a bracke...

Embodiment 2

[0042] The difference from Embodiment 1 is that when the abnormal value is equal to the quantity threshold, the edge distance between the detection picture and the reference image at multiple positions is used as the offset distance by the processing module, and the variation trend of multiple offset distances is judged by the processing module, The change trend includes gradual trend and equivalent trend, for example, the change trend of multiple offset distances of the rotation offset is 0.1mm, 0.2mm, 0.3mm, 0.4mm and 0.5mm, etc. The variation trend of multiple offset distances in translation offset is the equivalent trend of 0.3mm, 0.3mm, 0.3mm, 0.2mm, 0.2mm, and 0.2mm. shift, the processing module judges the shift mode as translation shift according to the change trend of the equivalent trend, and improves the accuracy of the shift mode disk to select an accurate shift distance calculation method.

Embodiment 3

[0045] The difference with Embodiment 2 is that, if Figure 5 As shown, a correction mechanism is placed at the place where the camera module is placed on the turntable 1. The correction mechanism includes a placement box 9, and a cavity is provided in the placement box 9, and an air inlet 10 filled with compressed air is provided at the bottom wall of the cavity. The air inlet 10 is connected to the gas source through a pipe, and a controlled air valve is arranged on the pipe, and the signal of the controlled air valve is connected to the control unit. An independent placement plate 12 is placed along the top, the placement plate 12 is a circular plate, the laser unit 7 is arranged in the placement plate 12, and a plurality of spiral fan blades 11 are welded on the side wall of the placement plate 12 facing the cavity, and the air inlet 10 Set towards any spiral fan blade 11, the processing module sends an inflation signal to the control unit when it judges that the camera mo...

Abstract

The invention relates to the technical field of fault testing. The invention particularly relates to a rotating disc type camera module detection system and method. The system comprises a processing module, a transmitting module, a detecting module and a prompting module which are located on a turntable loading and unloading station, the processing module receives the detection size of the cameramodule; the processing module sends a detection signal to the transmitting module and the detection module according to the detection size; the transmitting module lightens a laser light source with the area equal to that of the camera module according to the detection signal; the laser light source is positioned below the camera module; the detection module shoots a detection picture of the camera module according to the detection signal and sends the detection picture to the processing module; and the processing module identifies the brightness value in the detection picture, calculates theoffset of the camera module when the brightness value is greater than a brightness threshold, and sends a prompt signal to the prompt module for offset prompt when the brightness value is greater thanthe brightness threshold. Whether the position of the camera module deviates or not is detected, and the accuracy of subsequent detection of the camera module is improved.

Description

technical field [0001] The invention relates to the technical field of fault testing, in particular to a detection system and method for a turntable camera module. Background technique [0002] The camera module is an important component for mobile phones and other devices to realize the camera function.
