Description

Technical Field

[0001] The utility model relates to the field of physics, in particular to a visual detection technology, and specifically to a multi-camera detection module. Background Art

[0002] Visual inspection is a device that uses machines to measure and judge products instead of human eyes. The captured target is converted into an image signal through machine vision products and transmitted to a dedicated image processing system to detect whether the product has defects.

[0003] Existing visual inspection devices, however, only use a single camera, a single light source, and a single fixed angle. In actual testing, it's often necessary to capture images of objects with varying dimensions, materials, and colors. However, cameras with different parameters often have varying imaging quality for these features. A single camera cannot guarantee that all images of these diverse features are clear enough to meet testing requirements, resulting in reduced detection accuracy and increased rates of missed and false detections, which in turn impacts product quality and manufacturing efficiency. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a multi-camera inspection module, which overcomes the shortcomings of the existing technology, effectively reduces the height of the equipment, and can ensure all-round and multi-angle visual inspection of the side of the product, thereby effectively improving the comprehensiveness and accuracy of defect detection.

A drive motor is mounted on the hollow rotating platform, and the driving end of the drive motor is connected to the mounting plate through a transmission member inside the hollow rotating platform;

[0007] A plurality of mounting brackets are evenly installed on the outer edge of the mounting plate, each mounting bracket is arranged in an arc-shaped structure, and the center points of the arcs intersect at one point, an arc-shaped slide rail is arranged on the side of the mounting bracket, and the outer surface of the arc-shaped slide rail is slidably connected to the sliding bracket, and the outer side surface of the sliding bracket is fixedly installed with a side camera, and the shooting route of each side camera intersects with the shooting route of the main camera at one point.

[0008] Preferably, a lampshade is fixedly installed below the mounting plate.

[0009] Preferably, a plurality of notches are evenly opened on the side surface of the lampshade, and each notch corresponds to a shooting route of each side camera.

[0010] Preferably, the mounting frame includes an arc-shaped plate and a fixing plate which are arranged in an integrated structure. The fixing plate is fixedly installed at an outer edge position of the mounting plate, and the arc-shaped plate is arranged below the fixing plate.

[0011] Preferably, a plurality of strip-shaped holes are symmetrically provided on the surface of the fixing plate, and a threaded hole is provided at the outer edge of the mounting plate, and the strip-shaped holes and the threaded holes correspond to each other.

A driving motor 3 is installed on the hollow rotating platform 1; the driving end of the driving motor 3 is connected to the mounting plate 4 through the transmission member inside the hollow rotating platform 1; in this embodiment, the transmission member inside the hollow rotating platform 1 adopts a gear transmission mechanism, specifically, the driving end of the driving motor 3 cooperates with the input end of the hollow rotating platform 1, and the mounting plate 4 is connected to the output end of the hollow rotating platform 1; (wherein, the hollow rotating platform 1 adopts a well-known technical solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here);

[0022] Four mounting brackets 5 are evenly installed on the outer edge of the mounting plate 4. Each mounting bracket 5 is arranged in a quarter-circular arc structure, and the center points of the arcs intersect at one point. An arc-shaped slide rail 6 is arranged on the side of each mounting bracket 5. The outer surface of the arc-shaped slide rail 6 is slidably connected to a sliding bracket 7. The outer side of the sliding bracket 7 is fixedly installed with a side camera 8. The shooting route of each side camera 8 intersects with the shooting route of the main camera 2 at one point.

[0023] Working principle:

[0024] When in use, the main camera 2 can directly pass through the through-hole in the center of the hollow rotating table 1 and the mounting plate 4 to perform visual inspection of the product directly below, and by providing four mounting frames 5, the four side cameras 8 can slide along the curved slide rails 6 on the sides of the four mounting frames 5 respectively. In this embodiment, an arc-shaped rack parallel to or coaxial with the curved slide rail 6 can be provided on the mounting frame 5, a small motor can be installed on the slide frame 7, and a gear can be installed at the driving end of the small motor so that the gear and the arc-shaped rack are engaged. The operation of the small motor can be controlled to drive the entire slide frame 7 to slide along the curved slide rail 6. In addition, a drive motor 3 is installed on the hollow rotating table 1. The operation of the drive motor 3 can be controlled to drive the entire mounting plate 4 to rotate through the hollow rotating table, and then drive each side camera 8 to rotate horizontally, so that each side camera 8 can move in the horizontal and vertical directions, thereby ensuring all-round and multi-angle visual inspection of the side of the product, thereby effectively improving the comprehensiveness and accuracy of defect detection.
