Description

Multi-camera detection module Technical Field The invention relates to the field of physics, in particular to a visual detection technology, and specifically relates to a multi-camera detection module. Background The visual inspection is a device for measuring and judging products by using a machine instead of human eyes, and the picked-up targets are converted into image signals through the machine vision products and transmitted to a special image processing system, so that whether the products are defective or not is detected. The visual inspection device in the prior art is only provided with a single camera, a single light source and a single fixed angle. In practical experimental detection, image information acquisition is often required to be carried out on detected objects with characteristics of different sizes, different materials, different colors and the like, and cameras with different parameters have good or bad imaging quality on the characteristics, so that a single camera cannot ensure that all acquired detected object images with different characteristics are clear so as to meet detection requirements, thereby reducing detection accuracy, increasing omission rate and false detection rate, and further influencing product quality and manufacturing efficiency. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the multi-camera detection module, overcomes the defects of the prior art, effectively reduces the equipment height, and can ensure the omnibearing and multi-angle visual detection of the side surface of a product so as to effectively improve the comprehensiveness and the precision of defect detection. In order to achieve the above purpose, the invention is realized by the following technical scheme: The utility model provides a multi-camera detection module, includes the cavity revolving stage, the main camera is installed to cavity revolving stage top, the rotation of cavity revolving stage below is connected with the mounting panel, the through-hole has all been seted up to the center of cavity revolving stage and mounting panel correspondence, the shooting head of main camera is just opposite with the through-hole, install driving motor on the cavity revolving stage, driving motor's drive end passes through the inside driving piece of cavity revolving stage and is connected with the mounting panel transmission; The outer edge of mounting panel evenly installs a plurality of mounting brackets, and each mounting bracket all is the circular arc structure setting, and the centre of a circle point of circular arc intersects in a bit, the mounting bracket side is provided with the arc slide rail, arc slide rail surface sliding connection has the carriage, the equal fixed mounting of carriage lateral surface has the side camera, and the shooting route of each side camera intersects in a bit with the shooting route of main camera. Preferably, a lampshade is fixedly arranged below the mounting plate. Preferably, a plurality of notches are uniformly formed in the side face of the lampshade, and each notch corresponds to the shooting route of each side camera one by one. Preferably, the mounting frame comprises an arc-shaped plate and a fixed plate which are arranged in an integrated structure, the fixed plate is fixedly arranged at the outer edge position of the mounting plate, and the arc-shaped plate is arranged below the fixed plate. Preferably, a plurality of strip-shaped holes are symmetrically formed in the surface of the fixing plate, threaded holes are formed in the outer edge of the mounting plate, and the strip-shaped holes correspond to the threaded holes. The invention provides a multi-camera detection module. The camera has the advantages that the shooting head of the main camera 2 can directly penetrate through the through holes in the centers of the hollow rotary table and the mounting plate to visually detect products right below, and the four side cameras can slide along the arc-shaped sliding rails on the side surfaces of the four mounting frames respectively through the four mounting frames. In addition, install driving motor on cavity revolving stage, accessible control driving motor's operation to drive whole mounting panel through cavity revolving stage and rotate, drive each side camera then and carry out horizontal rotation, thereby make each side camera homoenergetic move in horizontal direction and vertical direction, thereby guarantee to carry out all-round, the visual inspection of multi-angle to the side of product, with comprehensive and the precision that has effectively improved defect detection.
