[0034] Embodiment
[0035] Please refer to Figure 1-6 , the present utility model provides a technical solution: a multi-light source vision adjustment mechanism, including two support frames 1. An installation plate 7 is installed on the top of the support frame 1. A camera 2 for visual shooting is provided on one side of the bottom of the installation plate 7; several light source bodies 8 are provided on one side of the bottom of the support frame 1 and are located below the camera 2. A light source controller is installed on one side of the light source body 8. During the scanning process of the camera 2, high-speed switching is continuously performed, and after the scanning is completed, image processing is performed to separate the pictures taken by the light source bodies 8 at different angles;
[0036] A first adjustment component 3 for adjusting the angle of the camera 2 is provided on one side of the installation plate 7;
[0037] The first adjustment component 3 includes a first fixing frame 31 and a second fixing frame 32. Second through holes 35 are opened at the four corners of the first fixing frame 31. First through holes 34 are opened at the four corners of the second fixing frame 32. A spherical ball 33 is ball-jointed at the center of one side of the second fixing frame 32. The diameter of the second through hole 35 is larger than the diameter of the first through hole 34. A limiting groove 36 is opened on one side of the installation plate 7 and is located outside the camera 2. The bottom of the first fixing frame 31 is fixed to the top of the installation plate 7. The bottom of one side of the second fixing frame 32 is installed outside the camera 2. Screws are inserted into one side of the second through hole 35 and are threadedly connected to the inner sides of the first through holes 34. The four screws are threadedly connected to the four first through holes 34 at different depths, so that the second fixing frame 32 drives the camera 2 to be at different angles; by adjusting the connection depth between the screw and the first through hole 34, the shooting angle of the camera 2 can be easily changed, greatly improving the shooting efficiency and creative space.
[0038] A base 4 is slidably connected to the outside of the support frame 1 through a slide rail, and a lifting assembly 5 for adjusting the height of the camera 2 is provided on one side of the base 4; the lifting assembly 5 includes two first limit plates 53 and two second limit plates 58. One side of the second limit plate 58 is rotatably connected to a first bolt 52 through a bearing, and one side of the first limit plate 53 is threadedly connected to a second bolt 54. The staff can visually observe the size of the scale line 55 so that both sides of the support frame 1 are at the same height. When the rotation of the first bolt 52 stops, then rotate the second bolt 54 so that the top of the second bolt 54 fits against the bottom of the slide plate 51. A first chute 57 is provided on one side of the support frame 1, and the outside of the first bolt 52 is threadedly connected to a slide plate 51 slidably connected to the inside of the first chute 57. A vertical plate 56 is fixed on one side of the support frame 1, and a scale line 55 is provided on the surface of the vertical plate 56. One side of the first limit plate 53 and the second limit plate 58 are both fixed to one side of the support frame 1, completing the adjustment of the height of the camera 2. By visually observing the scale line 55, the staff can accurately control the height of the camera 2, ensuring that the heights of the two support frames 1 are the same, thus avoiding inclination and distortion during the shooting process.
[0039] A second adjustment assembly 6 for adjusting the angle of the light source body 8 is provided on one side of the base 4;
[0040] The second adjustment assembly 6 includes two limit frames 66. Six support plates 61 are fixed on one side of the limit frame 66. Two second chutes 64 are provided on the inner wall of the support plate 61. A support rod 62 is rotatably connected to the inside of the second chute 64. An installation frame 63 is fixed between the support rods 62. Rotate the third bolts 65 on both sides of the support plate 61. The two third bolts 65 have different lengths downward, so that the bottom of the third bolts 65 pushes the installation frame 63 to rotate around the support rod 62. The outside of the light source body 8 is installed on one side of the bottom of the installation frame 63. One side of the limit frame 66 is fixed to one side of the bottom of the support frame 1. The two sides of the top of the support plate 61 are both threadedly connected to the third bolts 65, and the bottom ends of the third bolts 65 are located on one side of the top of the installation frame 63.
[0041] Working principle: When it is necessary to photograph a product, place the product at the bottom of the camera 2, and then the screws inserted into the inner side of the second through holes 35 can be rotated. At this time, the second fixing frame 32 rotates with the spherical ball 33 as the rotation point. At this time, according to the different depths of the four screws threadedly connected to the four first through holes 34 respectively, the second fixing frame 32 drives the camera 2 to be at different angles; by adjusting the connection depth of the screws and the first through holes 34, the shooting angle of the camera 2 can be easily changed, greatly improving the shooting efficiency and creative space, being able to capture more diverse product perspectives, and at the same time, the inclination and rotation angles of the camera 2 can be very finely controlled, and the shooting requirements of different products can be easily met.
[0042] Then rotate the first bolts 52 on both sides of the base 4 so that the first bolts 52 are threadedly connected to the sliding plate 51, and the sliding plate 51 can slide up and down inside the first chute 57, enabling the adjustment of the height of the camera 2. The staff can visually observe the size of the scale line 55 to make both sides of the support frame 1 at the same height. When the rotation of the first bolts 52 stops, then rotate the second bolts 54 so that the tops of the second bolts 54 fit against the bottom of the sliding plate 51. At this time, the adjustment of the height of the camera 2 is completed. By visually observing the scale line 55, the staff can accurately control the height of the camera 2 to ensure that the heights of the two support frames 1 are consistent, thus avoiding tilting and distortion during the shooting process. When the rotation of the first bolts 52 stops and the second bolts 54 are rotated so that their tops fit against the bottom of the sliding plate 51, the height of the camera 2 is firmly locked, ensuring good stability of the camera 2 at the adjusted position and reducing shaking and deviation during the shooting process;
[0043] When the irradiation angle of the light source body 8 needs to be adjusted, only need to rotate the third bolts 65 on both sides of the support plate 61 according to the light position. The two third bolts 65 have different lengths downward, so that the bottoms of the third bolts 65 push the mounting bracket 63 to rotate around the support rod 62. At this time, the angle of the light source body 8 at the bottom of the mounting bracket 63 can be adjusted. At this time, the camera 2 continuously performs high-speed switching during the scanning process and performs image processing after the scanning is completed. The pictures taken by the light source body 8 at different angles are separated to prepare for subsequent calculations. Combining the image features under different perspectives and different states of the light source body 8, the algorithm can better correctly identify the defects and improve the accuracy. By rotating the third bolts 65 with different lengths to adjust the irradiation angle of the light source body 8, images of the product under different lighting conditions can be obtained, providing richer information for subsequent image processing and defect recognition. Combining the image features under different perspectives and light source states can more accurately identify product defects, thereby improving the accuracy and reliability of detection.
[0044] The model of the camera 2 is: LBAS-U3200S-19C;
[0045] The model of the light source body 8 is: LL-180;
[0046] The model of the light source controller is: DCP-24V60W-2-T.
