[0042] Please refer to Figures 1 to 5 This utility model provides a detection device, including: a turntable 1, which can rotate around the center line of the turntable 1; arc-shaped light sources 2, at least two of which are arranged in a circumferential array around the center line of the turntable 1, the arc-shaped light sources 2 having an inwardly concave arc-shaped light-emitting surface facing the center line of the turntable 1, all the arc-shaped light sources 2 and the turntable 1 forming a detection space 100 that allows the workpiece to enter; each arc-shaped light source 2 is provided with a photographic detection hole 201 that penetrates into the detection space 100, and the light emitted by two adjacent arc-shaped light sources 2 is different in color.
[0043] In the actual inspection process, the workpiece is placed in the inspection area, and then the turntable 1 is rotated so that the concave arc-shaped light-emitting surface of an arc-shaped light source 2 faces the workpiece. The arc-shaped light source 2 then emits light, and the external inspection camera 4 can then take a picture of the workpiece through the imaging inspection hole 201 on the arc-shaped light source 2. It should also be noted that after one imaging inspection, the turntable 1 rotates so that another arc-shaped light source 2 is positioned between the inspection camera 4 and the workpiece. This other arc-shaped light source 2 illuminates the workpiece with a different color of light, thus performing another imaging inspection. In this embodiment, the inspection device can perform imaging inspections on workpieces of different colors and specifications by switching between different arc-shaped light sources 2. Furthermore, the imaging inspection hole 201 on the arc-shaped light source 2 allows the inspection camera 4 to better photograph the workpiece surface, resulting in better illumination and improved inspection accuracy.
[0044] Optionally, the arc-shaped light source 2 includes a light-shielding housing 21, an arc-shaped diffuser plate 22, and an arc-shaped lamp plate 23. The arc-shaped diffuser plate 22 is installed on the side of the arc-shaped lamp plate 23 near the center line of the turntable 1. The light-shielding housing 21 has a light-emitting port facing the center line of the turntable 1. The arc-shaped diffuser plate 22 is installed at the light-emitting port, and the concave arc surface of the arc-shaped diffuser plate 22 forms a concave arc-shaped light-emitting surface.
[0045] Specifically, an arc-shaped diffuser plate 22 is provided, which can make the light diffusion more uniform, thereby making the light intensity irradiating the workpiece surface more uniform, which is conducive to improving the accuracy of detection.
[0046] Optionally, the curved light panel 23 includes a curved circuit board 231 and an array of LEDs 232 mounted on the side of the curved circuit board 231 near the curved diffuser plate 22; the curved circuit board 231 and the curved diffuser plate 22 are parallel to each other, thereby improving the uniformity of the emitted light.
[0047] Optionally, a gap is provided between the ends of two adjacent arc-shaped light sources 2, which effectively facilitates heat dissipation and makes it easier and more convenient to place the workpiece into the inspection space 100. It should also be noted that the workpiece does not rotate with the turntable 1 and remains stationary during the inspection process.
[0048] Optionally, the center line of the photo detection hole 201 intersects with the center line of the turntable 1, which makes it easier for the camera 4 to perform photo detection. In this case, the photo detection hole 201 can be tilted.
[0049] Preferably, the center line of the photo detection hole 201 is perpendicular to the center line of the turntable 1.
[0050] Optionally, a rotary drive device 3 is provided on the side of the turntable 1 away from the arc-shaped light source 2. The rotary drive device 3 is used to drive the turntable 1 to rotate around the center line of the turntable 1. Specifically, the rotary drive device 3 can be an electric rotary device, a hydraulic rotary device, a pneumatic rotary device, or other rotary devices. Generally, the driving component of the rotary drive device 3 is a rotary motor.
[0051] Optionally, the inspection device also includes an inspection camera 4 for inspecting the workpiece through the photographic inspection hole 201. The inspection camera 4 is mounted on the side of the arc-shaped light source 2 away from the inspection space 100, and the inspection camera 4 does not rotate with the arc-shaped light source 2. The inspection camera 4 will remain in its original position, and by rotating the turntable 1, the photographic inspection hole 201 on the arc-shaped light source 2 will be aligned with the inspection camera 4, thereby meeting the actual inspection needs.
[0052] Optionally, the number of arc-shaped light sources 2 is even, and the emitted light colors of opposite arc-shaped light sources 2 are the same. Preferably, the number of detection cameras 4 is relative to the number of arc-shaped light sources 2, thereby enabling the capture of various imaging effects.
[0053] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
