Abstract
Description
Technical Field
[0001] This specification relates to the technical field of automation equipment, and in particular to a photo detection mechanism. Background Art
[0002] With the continuous advancement of technology, digital products such as smartphones and iPads are constantly being upgraded. Camera components are a crucial component, requiring inspection before installation. Manual inspection is often ineffective, prone to errors, and inefficient. Therefore, it is necessary to design automated equipment to automatically perform photo inspections on camera components, often referred to as visual inspection.
[0003] Visual inspection involves replacing the human eye with machines for measurement and judgment. It involves using machine vision products (i.e., image capture devices, available in CMOS and CCD) to convert captured objects into image signals. These signals are then transmitted to a dedicated image processing system, which converts them into digital signals based on pixel distribution, brightness, color, and other information. The image system then performs various operations on these signals to extract the target's features and, based on the results, controls the operation of on-site equipment. Visual inspection is invaluable in detecting defects and preventing defective products from reaching consumers. Lighting is a critical factor affecting the input of machine vision systems, directly impacting the quality of the input data and the effectiveness of the application. Utility Model Content

[0031] See also Figure 1 and Figure 2 The embodiment of the present application provides a photographing detection mechanism, comprising: a first mounting plate 1 , a photographing unit 2 , and a driving member 3 .
[0032] The first mounting plate 1 is vertically arranged. There are multiple camera units 2, which are spaced apart along the horizontal direction X and fixedly mounted on the first mounting plate 1. The camera unit 2 includes an image capture component 21 and a light source component 22, and the image capture component 21 is located above the light source component 22. The light source component 22 includes an axial light source 221, an arched light source 222, and an annular light source 223. The arched light source 222 and the annular light source 223 are located below the axial light source 221, and the arched light source 222 is located around the annular light source 223. The driving member 3 is connected to the first mounting plate 1 and is used to drive the first mounting plate 1 to move along the vertical direction Y.
[0033] The photographic inspection mechanism provided in this embodiment utilizes a driver 3 to drive the first mounting plate 1, which in turn moves the photographic unit 2 in the vertical direction Y. This allows for adjustment of the distance between the photographic unit 2 and the component to be inspected, thereby achieving optimal imaging results. Furthermore, a light source assembly 22 comprising an axial light source 221, an arched light source 222, and an annular light source 223 is disposed below the image capture assembly 21. This integrated design maximizes space utilization and allows for the combination of multiple light source effects. Utilizing the principle of diffuse reflection imaging, the optical path is uniform, and the array layout minimizes light source interference and creates complementary optical paths, achieving enhanced imaging results.
[0034] In addition, multiple photographing units 2 are provided to simultaneously photograph multiple components to be inspected, thereby improving inspection efficiency.
[0035] In this embodiment, if Figure 2 As shown, the bottom surfaces of the arched light source 222 and the annular light source 223 are flush. Preferably, the center lines of the axial light source 221, the arched light source 222, and the annular light source 223 all extend along the vertical direction Y and are located on the same straight line, thereby forming a four-part shadowless light with a better imaging effect.
[0036] Specifically, the image capturing component 21 includes a camera 211 and a lens 212. The camera 211 is located above the lens 212, and the lens 212 is located above the axial light source 221. The center line of the lens 212 and the center line of the axial light source 221 are located on the same straight line to achieve a better imaging effect.
[0037] like Figure 1 As shown, the photo detection mechanism also includes a plurality of vertically arranged second mounting plates 4, the second mounting plates 4 are fixedly mounted on the first mounting plate 1, and the photo unit 2 is mounted on the side of the second mounting plate 4 facing away from the first mounting plate 1, and the installation and fixation of the photo unit 2 is achieved through the second mounting plate 4.
[0038] Specifically, the image capture component 21 is fixedly connected to the top end of the second mounting plate 4 through the first fixing plate 5, and the arched light source 222 is fixedly connected to the bottom end of the second mounting plate 4 through the second fixing plate 6, that is, the fixed connection between the photo-taking unit 2 and the second mounting plate 4 is realized through the first fixing plate 5 and the second fixing plate 6.
[0039] like Figure 2 As shown, the axial light source 221 is fixedly connected to the second mounting plate 4 via a movable plate 7. The position of the movable plate 7 relative to the second mounting plate 4 in the vertical direction Y is adjustable, thereby adjusting the distance between the axial light source and the lens 212 or the arched light source 222 to achieve a better imaging effect. The movable plate 7 is connected to the second mounting plate 4 via bolts. Before taking photos and testing, the specific position of the axial light source 221 is adjusted and determined, and the movable plate 7 is fixed to the second mounting plate 4 using bolts.
[0040] Specifically, the bottom of the annular light source 223 is fixedly connected to the bottom of the arch light source 222 through a third fixing plate 8, and the end of the axial light source 221 away from the second mounting plate 4 and the end of the arch light source 222 away from the second mounting plate 4 are fixedly connected through a deformable soft plate 9 to facilitate adjustment of the distance between the axial light source and the arch light source 222.
[0041] like Figure 1 As shown, the photo detection mechanism further includes a third mounting plate 10 vertically disposed on the side of the first mounting plate 1 facing away from the second mounting plate 4. One end of the driving member 3 is fixedly connected to the third mounting plate 10. A slide rail 11 extending along the vertical direction Y is provided on the side of the third mounting plate 10 facing the first mounting plate 1. The first mounting plate 1 is slidably connected to the slide rail 11 via a slider 12, thereby enabling the driving member 3 to drive the first mounting plate 1 to move the multiple photo units 2 along the vertical direction Y.
