Embodiment approach

[0036] The scanning mechanism includes a positioning rod 9 installed at a specific position, the outer wall of the positioning rod 9 is fixedly connected with the mounting seat 8, the outer wall of the mounting seat 8 is rotatably connected with the second rotating shaft 14, and the outer wall of the second rotating shaft 14 is fixedly connected with the second gear 13 With the launcher 7, the upper limit of the positioning rod 9 is slidably connected with a rack 15, the rack 15 is meshed with the second gear 13, the launcher 7 can emit detection light, and also includes a mechanism for driving the rack 15 to move up and down.

[0037] Such as figure 1 As shown, the output end of the launcher 7 faces the convex surface of the convex lens sheet 5, and when the control rack 15 moves up and down, it can drive the second gear 13 to rotate, thereby enabling the launcher 7 to rotate along the outer wall of the second rotating shaft 14, The angle of the detection light can then be ad...

Embodiment 1

[0041] The control mechanism is used to control the rotation of the convex lens sheet 5. The top of the detection table 1 is rotatably connected with the first installation shaft 18, the limit mechanism is installed on the top of the first installation shaft 18, and the bottom of the detection table 1 is fixedly installed with a driving first installation shaft. 18 rotates the first motor 19, and the emission device 7 adjusts the irradiation angle at an appropriate point through the adjustment mechanism.

[0042] Such as Figure 1 to Figure 4 As shown, the limit mechanism clamps the convex lens sheet 5, and the limit mechanism is fixedly installed on the top of the first installation shaft 18. At this time, the first motor 19 drives the first installation shaft 18 to rotate, thereby driving the installation box 20 to rotate, so that The limit mechanism can drive the convex lens sheet 5 to rotate, and then drive the emitting device 7 to generate an angle through the adjusting m...

Embodiment 2

[0049] The control mechanism is used to control the launch device 7 to revolve along the convex lens sheet 5, the top of the detection table 1 is fixedly connected with the second installation shaft 28, the limit mechanism is installed on the top of the first installation shaft 18, and the outer wall of the second installation shaft 28 is connected to There is a shaft sleeve 27, the outer wall of the shaft sleeve 27 is fixedly connected with the installation crank 23 and the third gear 25 in turn from top to bottom, the adjustment mechanism and the positioning rod 9 are fixedly connected to the top of the installation crank 23 away from the second installation shaft 28, and the detection A second motor is also provided at the bottom of the table 1, the output end of the second motor passes through the top of the detection table 1, and the outer wall of the output end is fixedly connected with a fourth gear 26 meshing with the third gear 25.

[0050] Such as Figure 5 to Figure...

Abstract

The invention discloses a detection device for a mobile phone camera module, and the device comprises a detection platform, the top of the detection platform is provided with a limiting mechanism for horizontally clamping a convex lens, and the top of the detection platform is provided with a height-adjustable detection plate. A scanning mechanism for continuously emitting a single beam of detection light to the surface of the convex lens is further arranged at the top of the detection table, the bottom of the detection plate can receive the detection light reflected from the surface of the convex lens, and the detection light can form a detection light spot at the bottom of the detection plate; the light detection device further comprises a control mechanism for driving the detection light and the convex lens to rotate relatively, and meanwhile, the light detection device further comprises an adjusting mechanism for driving the detection light to generate angle deflection, so that the detection light can scan the convex lens surface of the convex lens along with rotation of the convex lens. And the surface of the convex lens can be comprehensively scanned, and the detection accuracy is high.

Description

technical field [0001] The invention relates to the field of mobile phone camera technology, in particular to a detection device for a mobile phone camera module. Background technique [0002] Camera modules are widely used in electronic products such as mobile phones. Camera modules include lenses, lenses and filters. Among them, lenses are generally composed of multiple lenses, mainly including convex lenses. In order to ensure that the surface of the lens is smooth and free of defects, and in When installing the camera module, it is also necessary to ensure that the surface of the convex lens is not dirty, so surface inspection of the lens is required. [0003] However, the existing surface inspection is through manual identification, which cannot accurately remove defective products. Contents of the invention [0004] The purpose of the present invention is to provide a detection device for mobile phone camera module, equipped with the ability to detect light on the s...
