Problems solved by technology

[0004] In addition, there is still a detection method that uses a camera combined with an AI algorithm. Due to the complexity of the tile background and the variety of tile types, the actual application effect is poor, and the inspection requirements of the manufacturer cannot be met for the time being.

Embodiment

[0025] The tiles 3 are transported by the belt conveyor assembly 1. When the tiles 3 run to the photoelectric trigger assembly 4, the photoelectric trigger assembly 4 sends out a photoelectric trigger signal, which respectively triggers the laser profile scanning assembly 5 and the camera acquisition system 8 to start working. The camera acquisition system 8 includes at least one camera group, which may be two groups, the first camera group 7 and the second camera group 12, and also includes a light source group 6, wherein the light source group may be at least one group.

[0026] The first camera group 7 and the second camera group 12 start to shoot, and the camera acquisition system 8 and the laser profile scanning component 5 start to receive the pulse trigger signal of the meter wheel trigger component 2, and shoot the tile 3 to be tested, and pass the preset shooting The number of lines or the number of scanning pulses is limited to work until the end signal of the photoel...

Abstract

The invention provides a ceramic tile defect detection device adopting a laser and camera composite detection mode. The ceramic tile defect detection device comprises a belt conveyor assembly, a photoelectric trigger assembly, a meter counting wheel trigger assembly, a camera acquisition system, a laser contour scanning assembly, an image processing unit, an upper computer display assembly and a marking / reminding assembly. The belt conveyor assembly conveys to-be-detected ceramic tiles for operation; the photoelectric triggering assembly is used for sending out a photoelectric triggering signal to start or stop working; the meter counting wheel triggering assembly is used for sending a scanning pulse triggering signal; and the image processing unit is used for processing the picture shot by the camera acquisition system and the point cloud data acquired by the laser contour scanning assembly, and transmitting a detection result to the upper computer display assembly and the marking / reminding assembly after completion. The invention further provides a method of the device, the ceramic tiles are detected in a laser and camera composite detection mode, complete ceramic tile defect detection can be achieved, and more accurate defect classification, qualitative analysis and quantitative analysis can be achieved on the defects.

Description

technical field [0001] The invention belongs to the technical field of defect detection methods, and in particular relates to a ceramic tile defect detection device and a grading method of a combined detection method of laser and camera. Background technique [0002] With the improvement of the high-quality level of the manufacturing industry, the current ceramic product production line has basically completed the automation transformation. At present, manual visual inspection is often used to detect ceramic defects on the assembly line. Due to the detection accuracy and consistency of detection requirements, it cannot meet the requirements of factory quality improvement. , leading to more complaints from end customers; there are also relatively poor employment environment in ceramic manufacturing plants, high labor intensity, personnel flow and recruitment problems have become the bottleneck of capacity expansion, and ceramic manufacturers urgently need to automate the exist...
