Embodiment

[0025] Example: such as figure 1 and figure 2 As shown, a BOWL light source for AOI visual detection is equipped with a surrounding light detection mechanism, including a bracket 1, a BOWL light source 9 and a CCD camera. The bracket 1 has a detection area 1-1, and the bracket 1 is located in the detection area 1-1. The four sides are respectively provided with strip light sources 2 for illuminating the detection area. The CCD camera includes a front viewing angle CCD camera 3 positioned directly above the detection area and a side viewing angle CCD camera 4 positioned on the side of the detection area. The BOWL light source 9 Located below the front view angle CCD camera 3 and above the detection area 1-1, an up and down sliding mechanism 5 is respectively arranged between the above-mentioned front view angle CCD camera 3, the side view angle CCD camera 4, the BOWL light source 9 and the support 1, and the front view angle The CCD camera 3 , the side view CCD camera 4 and t...

Abstract

The invention discloses a detection mechanism provided with BOWL light source cooperating with strip light sources on the periphery for AOI visual detection. The detection mechanism comprises a bracket, the BOWL light source and CCD cameras, wherein the bracket is provided with a detection area, and the strip light sources used for emitting light to the detection area are arranged on the periphery of the detection area of the bracket; the CCD cameras comprise a front view angle CCD camera located right above the detection area and a side view angle CCD camera located on the side surface of the detection area; a vertical sliding mechanism is arranged between the bracket and each of the front view angle CCD camera, the side view angle CCD camera and the BOWL light source, and the height of each of the front view angle CCD camera, the side view angle CCD camera and the BOWL light source can be vertically adjusted relative to the bracket through the vertical sliding mechanism. The detection mechanism can solve the problem of insufficient and non-uniform light emission during AOI visual appearance detection, pictures shot by the CCD cameras are of higher quality due to good light emission effect, and result determination of AOI visual appearance detection is more accurate.

Description

technical field [0001] The invention relates to the field of AOI visual detection, in particular to a detection mechanism for AOI visual detection. Background technique [0002] The inspection mechanism in the existing AOI visual inspection device is relatively simple, and it is all supplemented by the light source of the incandescent lamp, which cannot solve the problem of insufficient and uneven lighting during the AOI visual appearance inspection. However, due to the poor lighting effect, the quality of the photos taken by the CCD camera (CCD image sensor) is not high, so the results of the AOI visual appearance inspection cannot be accurately judged. Contents of the invention [0003] The purpose of the present invention is to provide a BOWL light source for AOI visual inspection with surrounding strip light detection mechanism, which can solve the problem of insufficient and uneven lighting during AOI visual appearance inspection, and because of the good lighting effe...
