Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, and more specifically, to a positioning mechanism and a detection device. Background Technology

[0002] In the current smartphone manufacturing industry, the quality of mobile phone cameras is directly related to the user's photography experience and the overall performance of the device. Among them, camera concentricity, as one of the important indicators for measuring the precision of camera assembly, has a crucial impact on image quality.

[0003] Therefore, existing technologies use visual inspection to confirm whether the camera concentricity is up to standard. This requires a positioning mechanism to locate the phone during inspection. Traditional positioning mechanisms often have fixed models, necessitating the replacement of different mechanisms when inspecting phones of different sizes, which is inconvenient. Therefore, we propose an improvement, creating a positioning mechanism and inspection device. Utility Model Content

[0029] The bottom of the third limiting block 509 is slidably connected to the top of the platform 5 to limit the third limiting block 509 and reduce the situation where the third limiting block 509 rotates along with the second hand-tightening bolt 507 during rotation.

[0030] Furthermore, the top of the platform 5 is provided with a pick-up and put-down slot 510, which facilitates the insertion of fingers when picking up and putting down the mobile phone.

The third linear module 4 and the protective box 101 are both connected to the cabinet 1 by bolts.

[0034] Furthermore, a detection unit located inside the protective box 101 is installed on the top of the cabinet 1. The detection unit includes two support frames 2 installed on the top of the cabinet 1. A first linear module 201 is connected between the two support frames 2. A second linear module 202 is connected to the moving end of the first linear module 201. A first connecting plate 203 is connected to the moving end of the second linear module 202. A CCD camera 204 and a fill light 205 located below the CCD camera 204 are installed on the side of the first connecting plate 203. The support frame 2 is connected to the first linear module 201 and the cabinet 1 by bolts. The second linear module 202 is connected to the first connecting plate 203 and the first linear module 201 by bolts.

[0038] When in use, first adjust the positioning mechanism. Specifically, first place the mobile phone on the top of the platform 5, and then rotate the first hand-tightening bolt 503 and the second hand-tightening bolt 507 to move the third limiting block 509 and the first limiting block 505 toward the mobile phone. This causes the side of the mobile phone to contact the L-shaped positioning rod 501, the second limiting block 506, the first limiting block 505 and the third limiting block 509 but not to clamp or fix it. In other words, the mobile phone can still be removed.

[0039] During testing, the phone screen is placed face down on top of the platform 5. The phone is transported by the third linear module 4 through the inlet / outlet 104 into the protective box 101 and reaches the fill light 205 and CCD camera 204. The CCD camera 204 captures information from the phone's camera for testing. After testing is completed, the third linear module 4 drives the platform 5 and the phone to move from the inlet / outlet 104 to the outside of the protective box 101. The tested phone can then be manually removed.
