Description

Technical Field

[0001] The present application relates to the technical field of sorting equipment, and in particular to a defect visualization lighting device. Background Art

[0002] In the process of material sorting, cameras are needed to identify materials. At the same time, a machine will be set up directly above the camera, which will cause the light to be blocked. Due to the low brightness, it may cause missed recognition or misrecognition, affecting the accuracy of the camera's recognition of materials. Therefore, it is necessary to add additional lights to the materials to be identified.

[0003] The existing solution is to provide four outside-inward light sources above the material conveyor belt to increase brightness, but this method still has room for improvement. The characteristic of fisheye cameras is that the center is bright and the four sides are dark. The outside-inward light on the market will make the center area reflective and the surrounding area dark, which will lead to the possibility of missed recognition or misrecognition of materials passing through the conveyor belt, affecting visual recognition.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0030] Embodiment 1

Figure 1 and Figure 2 The defect visualization lighting device includes a fisheye lens 2 installed in the machine 1 for identifying materials, and a fill light 3 is arranged inside the machine 1. The fill light 3 is arranged on one side of the fisheye lens 2, and the irradiation angle of the fill light 3 is arranged to be inclined in the direction away from the fisheye lens 2. When identifying materials, the fill light 3 is turned on, and the light emitted by the fill light 3 is irradiated to the surroundings, and the remaining light will illuminate the identification area corresponding to the fisheye lens 2, thereby achieving the effect of overall fill light. At the same time, by using the residual light of the fill light 3 for fill light, the phenomenon that the middle area appears to be reflected due to excessive brightness and the surrounding area becomes dark can be reduced, thereby improving the accuracy of material identification.

[0032] Reference Figure 1 and Figure 2A plurality of fill lights 3 are arranged around the fisheye lens 2, and the plurality of fill lights 3 are arranged obliquely in a direction away from the fisheye lens 2. The identification area is illuminated by the residual light of the plurality of fill lights 3, so as to achieve an overall fill light effect. A mounting bracket 4 is arranged in the machine 1, and the fill light 3 is mounted on the mounting bracket 4 by bolts, and the mounting bracket 4 is mounted in the machine 1 by bolts, so as to install the fill light 3 to a designated position.

[0033] Reference Figure 2 and Figure 3 The mounting bracket 4 includes a support plate 5 and a mounting frame 6. The support plate 5 is arranged at the end of the mounting frame 6. The mounting frame 6 is mounted on the machine 1 through the support plate 5, and the fill light 3 is mounted on the mounting frame 6. The support plate 5 is arranged in a direction toward the outside of the machine 1, and the width of one side of the support plate 5 close to the outside of the machine 1 is smaller than the width of the other side, so that after the mounting bracket 4 is installed in the machine 1, the fill light 3 is arranged in an inclined shape in the vertical direction.

[0034] The implementation principle of this embodiment is: the fill light 3 is set to be inclined in the direction away from the fisheye lens 2, and the identification area is filled with light through the residual light of the fill light 3, so that the fisheye lens 2 can identify the material and improve the recognition effect.

[0035] Embodiment 2

[0036] The present application discloses a defect-visualizing lighting device, referring to Figure 4 and Figure 5 , which is different from the first embodiment in that the support plate 5 includes a mounting portion 51 and a rotating portion 52, the mounting frame 6 is connected to the rotating portion 52, and the mounting portion 51 is connected to the machine 1. A mounting groove 7 is provided on the mounting portion 51, and the rotating portion 52 is rotatably arranged in the mounting groove 7. A through bolt 8 is provided at the rotating end of the rotating portion 52, that is, the rotating portion 52 is rotatably installed in the mounting groove 7 through the through bolt 8. A stopper 9 for fixing the rotating portion 52 is provided on the rotating portion 52. During installation, the inclination angle of the fill light 3 can be adjusted by rotating the rotating portion 52, so that the angle of the fill light 3 can be adjusted or corrected according to the recognition effect.

[0037] Reference Figure 4 and Figure 5, an arc groove 71 is provided on the mounting portion 51, and the arc groove 71 is arranged in an arc shape around the rotation axis of the rotating portion 52.

When the rotating portion 52 is rotated, the limiting screw 91 is driven to slide in the arc groove 71. After the adjustment is completed, the limiting sleeve 92 is rotated until the limiting sleeve 92 abuts against the side of the mounting portion 51, thereby fixing the rotating portion 52 and then fixing the fill light 3.

[0038] Reference Figure 4 and Figure 5 A plurality of friction strips 921 are arranged on one side of the limiting sleeve 92 close to the mounting portion 51. The plurality of friction strips 921 are evenly distributed on the limiting sleeve 92. The limiting sleeve 92 abuts against the mounting portion 51 through the friction strips 921, thereby increasing the friction between the limiting sleeve 92 and the mounting portion 51, thereby increasing the stability of the rotating portion 52 and reducing the deviation of the fill light 3.
