[0002] In the prior art, the detection of the surface features of the arc surface of the frame of an electronic device usually adopts illumination methods such as surface light source and coaxial light source.

[0003] However, in actual application, it was found that since the arc surface of the frame of some electronic devices has a certain curvature, when using traditional surface light sources for illumination, the light emitted by traditional surface light sources and coaxial light sources is often not evenly distributed on the arc surface, resulting in some areas of the arc surface of the mobile phone frame being too bright while other areas are relatively dark, making the edge contours and subtle surface features blurred and difficult to accurately capture and analyze. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0028] Existing light sources for detecting the surface features of the arc surface of the frame of electronic devices include surface light sources, coaxial light sources, etc. For the detection of the arc surface of the mobile phone frame, since the structural design of the mobile phone frame is arc-shaped, the light spots of traditional surface light sources and coaxial light sources will produce dark areas when irradiating its arc surface. In addition, the surface light of the detected frame is uneven when these light sources are irradiated, making the arc surface features of the mobile phone frame unclear. Therefore, when the lens takes the image, the acquired image will be unclear, making it difficult to detect defects in the detected frame.

[0029] Based on this, this embodiment provides a frame arc surface detection light source 100, please refer to Figure 1-3 As shown, it includes: a detection area 11a, a lamp housing 110 and a light-emitting body 120; wherein, the detection area 11a is used to place the detected frame 200, and by placing the detected frame 200 in the detection area 11a, the light 31a of the detection light source 100 can be irradiated onto the detected frame 200, and the image is taken by the lens to realize defect detection of the detected frame 200; further, the lamp housing 110 is arranged on the outside of the detection area 11a; the light-emitting body 120 is installed on the lamp housing 110, and the light 31a of the light-emitting body 120 passes through the lamp housing 110 and / or directly irradiates the detection area 11a; wherein the light-emitting body 120 is coaxial with the central axis of the lamp housing 110, so that the light 31a of the light-emitting body 120 can be irradiated to different arc segments of the detected frame 200 located in the detection area 11a respectively.

[0030] Preferably, the light-emitting body 120 includes a first light-emitting component 211, which is installed at the bottom end of the lamp housing 110, and the light 31a of the first light-emitting component 211 is reflected in the lamp housing 110 and then irradiated toward the detection area 11a; it can be understood that in this embodiment, the inner wall of the shell is provided with a diffuse reflection wall 131, and the light 31a of the first light-emitting component 211 installed in the shell is diffusely reflected by the diffuse reflection wall 131, so that it is emitted outward and irradiated toward the detected frame 200 of the detection area 11a; in addition, the advantage of this structural design is that the light 31a of the first light-emitting component 211 can be irradiated to the top surface and one of the side surfaces inside the shell, thereby performing sufficient diffuse reflection, and then irradiating the detected frame 200 of the detection area 11a from one side.

[0031] Preferably, the light emitting body 120 includes a second light emitting member 212, and the second light emitting member 212 is installed on the side of the lamp housing 110 away from the detection area 11a. The lens concentrated in this embodiment is installed on the second light emitting member 212, and the lamp housing 110 is provided with a transmission port 21a. The purpose of designing the transmission port 21a is that the transmission port 21a can be used for the camera to illuminate the detected frame 200 of the detection area 11a so as to take an image, and at the same time, the light 31a of the second light emitting member 212 passes through the transmission port 21a to illuminate the detection area 11a, thereby supplementing the light 31a at the transmission port 21a to avoid the light 31a at the transmission port 21a being weak. It can be understood that the shell in this embodiment is set to a ring structure, and the structure The structural design makes the light-emitting side of the shell and the side for installing the second light-emitting component 212 both have arc-shaped structures. The arc-shaped structure allows the light 31a emitted from the second light-emitting component 212 and the first light-emitting component 211 to illuminate different arc segments of the detected frame 200, thereby achieving the goal of lighting up each arc segment of the detected frame 200, so that the lens can obtain a clearer image, thereby making it easier to detect defects in the detected frame 200; in addition, in this embodiment, the second light-emitting component 212 is installed on the side of the lamp housing 110 away from the detection area 11a. This design can ensure that the installation of the second light-emitting component 212 will not affect the normal illumination of the detected frame 200 by the light 31a of the first light-emitting component 211.

[0032] According to the above scheme, it can be understood that this embodiment designs the light emitting body 120 to be coaxial with the central axis of the lamp housing 110, so that the light 31a of the light emitting body 120 can be respectively irradiated to different arc segments of the detected frame 200 located in the detection area 11a, thereby avoiding uneven illumination of the light 31a of different arc segments of the detected frame 200, resulting in dark areas in some arc segments, and improving the illumination intensity and uniformity of the light 31a on the arc-shaped detected frame 200, so that the edge contour and subtle surface features of the detected frame 200 are clearer, thereby ensuring that the lens can accurately capture a clearer image, so that defects in the detected frame 200 can be more easily detected.

[0033] Preferably, there are at least two second light-emitting members 212, and each light-emitting body 120 passes through the lamp housing 110 to illuminate the detection area 11a. Optionally, the number of second light-emitting members 212 ranges from 2 to 5, and the angles 22a formed by any two adjacent second light-emitting members 212 and the central axis of the lamp housing 110 are equal.

[0034] According to the above scheme, preferably, three light-emitting bodies 120 are set, and the angle 22a formed by any two adjacent light-emitting bodies 120 and the central axis of the lamp housing 110 is 60°; it can be understood that the advantage of this structural design is that the illumination requirements of different arc segments of the detected frame 200 can be met under the premise of installing three second light-emitting parts 212, and the 60° angle is a more reasonable range for coaxial light source illumination, thereby making the illumination efficiency of the detection light source 100 better.

[0035] Preferably, a detection port 12a is provided on one side of the lamp housing 110 for allowing the detected frame 200 to move into the detection area 11a. In this embodiment, the ratio of the diameter of the detection port 12a to the length of the lamp housing 110 is 1 / 3.

[0036] Preferably, it also includes a light-transmitting plate 132 installed on the side of the lamp housing 110 facing the detection area 11a, the number of transmission ports 21a corresponds to the number of light-emitting bodies 120, and the transmission ports 21a are arranged through the light-transmitting plate 132; it can be understood that the light 31a of the first light-emitting component 211 is diffusely reflected in the lamp housing 110, and then passes through the light-transmitting plate 132 to irradiate the detection area 11a, and the light 31a of the second light-emitting component 212 passes through the transmission port 21a on the other side of the lamp housing 110 to irradiate the detection area 11a. Since the transmission port 21a is set to pass through the light-transmitting plate 132, it can be understood that the light 31a of the second light-emitting component 212 does not need to pass through the light-transmitting plate 132 to irradiate the detected frame 200 of the detection area 11a.

[0037] To sum up, the utility model provides a light source for detecting the arc surface of the frame. By designing the light-emitting body to be coaxial with the central axis of the lamp housing, the light of the light-emitting body can be respectively irradiated to different arc segments of the detected frame located in the detection area, thereby avoiding uneven light irradiation to different arc segments of the detected frame, resulting in dark areas in some arc segments, and improving the light irradiation intensity and uniformity of the arc-shaped detected frame, making the edge contour and subtle surface features of the detected frame clearer, thereby ensuring that the lens can accurately capture a clearer image, so that defects in the detected frame can be more easily detected.
