Problems solved by technology
Traditional detection methods mainly rely on manual observation, but manual observation has limitations and unknown factors, and with the continuous improvement of machining precision, the requirements for product quality inspection and real-time monitoring automation are getting higher and higher. Machine vision And the rapid development of image processing technology has greatly improved the automation of product quality monitoring
Machine vision inspection technology has been relatively mature in low-speed and low-resolution application fields. For online inspection environments with high speed requirements, high-speed cameras are commonly used for inspection at present, which require cameras to achieve high-speed acquisition, high resolution and huge data volume. processing, but the current high-speed camera is extremely expensive, and even if the high-speed camera is used, the problem of online detection of high-speed moving products has not been solved

Embodiment Construction
[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0035] like figure 1 As shown, the present embodiment proposes a low-speed camera to realize a high-speed moving product quality inspection device, which includes an imaging system 1, a high-speed camera moving device 2, a bracket 3, a high-speed moving inspected product 4 and a control system. The detection device proposed in this embodiment is installed above the production line of the product to be detected 4, and the visual detection technology is used. When the product moves at a high speed on the production line, the imaging system located above is driven by the high-speed camera moving device 2. Reduce the relative movement speed between the camera and the product, and trigger the camera through the difference in the number of pulses generated by the photoelectric encoder on the drive motor of the production line and the l...

The invention discloses a high-speed moving product quality inspection device, which includes an imaging system, a high-speed camera moving device, a bracket, a product to be inspected and a control system. The camera high-speed moving device is installed on the top of the bracket, and the imaging system is installed on the camera high-speed moving device, which can move along the moving direction of the inspected product driven by the camera's high-speed moving device to reduce the relative speed between the camera and the inspected product , using the generated displacement difference to complete image acquisition at different positions on the product surface. The invention can realize the online detection of the quality of high-speed moving products by the low-speed camera, and has the advantages of simple operation, high degree of automation, high detection precision, low cost and the like.
Description
technical field [0001] The invention relates to the technical field of machine vision detection, in particular to a device for detecting the surface quality and appearance size of high-speed moving products. Background technique [0002] The surface quality and appearance size of products are an important part of product quality inspection. Surface defects and dimensional deviations of products will have a great impact on product use and subsequent processing, and even cause significant property losses. Therefore, in the production process of products, strict inspections of surface quality and dimensions are required. Traditional detection methods mainly rely on manual observation, but manual observation has limitations and unknowable factors, and with the continuous improvement of machining accuracy, the requirements for product quality detection and real-time monitoring automation are getting higher and higher. Machine vision And the rapid development of image processing ...
