[0037] Through the above structure, the working principle of the high-precision multi-view synchronous visual inspection device provided by this application is as follows: The product is placed on the conveyor belt 14 of the conveyor frame 13. As the conveyor belt 14 rotates, the product gradually moves toward the direction of being transported to the inspection table 1. When the product is transported to the edge of the conveyor belt 14 close to the inspection table 1, the electric slide 262 is controlled to move toward the gantry 2 on the electric guide rail 261. At the same time, the electric telescopic rod 263 is controlled to extend and the electric telescopic rod 3 265 is controlled to extend. The electric telescopic rod 263 drives the connecting block 264, the electric telescopic rod 3 265 and the push block 266 to move horizontally and linearly. The rod 3 265 drives the push block 266 to move vertically and linearly, so that when the push block 266 is aligned with the product, the electric slide 262 is continuously controlled to slide on the electric guide rail 261, and the push block 266 can be used to push the product on the conveyor belt 1 4 onto the transparent tempered glass 8. When the infrared sensor 24 on the left inner wall of the gantry 2 detects that the product has reached the predetermined detection position, the electric slide 262 is controlled to move back to the original position on the electric guide rail 261, and the electric telescopic rod 2 263 and the electric telescopic rod 3 265 are controlled to shrink and reset, so that the push block 266 returns to the original position; After the controller 27 receives the signal from the infrared sensor 24, it controls the drive motor 16 to start according to the preset program. The drive motor 16 drives the lower transmission shaft 18 and the main pulley 20 to rotate, and the secondary pulley 19 and the upper transmission shaft 17 connected thereto are driven to rotate through the belt 21, so that the upper transmission shaft 17 and the lower transmission shaft 18 can rotate at the same time. The active bevel gears 22 at the right ends of the upper transmission shaft 17 and the lower transmission shaft 18 are respectively engaged with the driven bevel gears 23 on the upper vertical shaft 111 and the lower vertical shaft 131, thereby driving the upper bracket 11 and the lower bracket 13 to rotate at the same time, so that the three upper industrial cameras 12 and the three lower industrial cameras 14 rotate accordingly. At this time, the three upper industrial cameras 12 can be used to The upper surface of the product is visually inspected. The three lower industrial cameras 14 can be used to conduct a comprehensive visual inspection of the upper surface of the product. During the inspection process, by controlling the extension of the three electric telescopic rods 115, the three upper industrial cameras 12 can be vertically lowered while rotating, so that the side parts of the product can be visually inspected in all directions. In addition, during the inspection process, by controlling the forward and reverse rotation of the upper adjustment motor 119, the shooting angle of the upper industrial camera 12 can be flexibly adjusted. By controlling the forward and reverse rotation of the lower adjustment motor 138, the shooting angle of the lower industrial camera 14 can be flexibly adjusted, so that the best inspection viewing angle can be obtained, further improving the inspection accuracy and adaptability. At the same time, the controller 27 can control the fill light 25 to light up as needed to provide a suitable lighting environment for visual inspection. The captured visual images and visual inspection results will be transmitted to the controller 27 and displayed on its display screen for analysis and judgment by the operator; After the comprehensive visual inspection of the product is completed, the three electric telescopic rods 115 are controlled to retract and reset, so that the three upper industrial cameras 12 rise back to their positions, and then the drive motor 16 is stopped, and the electric slide 262 is controlled to move on the electric guide rail 261 toward the gantry 2. At the same time, the electric telescopic rod 263 is controlled to extend and the electric telescopic rod 3 265 is controlled to extend, so that the push block 266 is aligned with the product, and the electric slide 262 is continued to be controlled to slide on the electric guide rail 261. The push block 266 can be used to push the inspected products on the transparent tempered glass 8 onto the conveyor belt 26, and the conveyor belt 26 can be used to transport the inspected products away, thus completing the high-precision multi-view synchronous visual inspection and circulation process of the product. According to the above operating steps, the next product can be subjected to comprehensive visual inspection.
