Machine vision technology based leather detection device and detection method

Abstract

The invention discloses a machine vision technology based leather detection device. The device includes a support, an industrial camera, an LED lamp and a control device; the industrial camera can take pictures of leather on a conveyor belt; the LED lamp can illuminate the leather on the conveyor belt; and the control device can obtain the area and position information of the leather by taking pictures of the leather on the conveyor belt through the industrial camera, and control a nozzle to perform spraying on the leather on a corresponding position or with a corresponding area on the conveyor belt when the leather is conveyed to a spraying chamber by the conveyor belt. A leather detection method is also disclosed. The method includes the following steps: 1, performing camera calibrationon the industrial camera, and determining the position of a spray gun and the speed of the conveyor belt being V; 2, obtaining the area of the leather or the position information of the leather on theconveyor belt; and 3, controlling, by the control device, the spray gun to perform spraying on the leather on the corresponding position or with the corresponding area. Thus, the positions of the leather can be accurately detected and measured; the scope of detecting and measuring the positions of the leather is large; and the device and method are stable and reliable in operation.

Description

technical field [0001] The invention belongs to the technical field of automatic detection of leather production, in particular to a leather detection device based on machine vision technology and a detection method thereof. Background technique [0002] The leather industry is a large industry covering the main industries such as tanning, shoemaking, leather clothing, leather goods, fur and its products, and supporting industries such as leather chemicals, leather machinery, leather hardware, and shoe materials. Among them, spraying is one of the important processes in the leather production process. In order to improve production efficiency and production quality, spraying is completed in an automated manner. [0003] as attached figure 1 , The leather spraying machine is made of parts such as conveyor belt 1, leather detection device 2, spray chamber 3, drying chamber 4 and spray gun 5. The conveyor belt 1 realizes the transportation of the leather 10 in the whole spray...

AI Technical Summary

Problems solved by technology

However, this leather detection device and method has the following disadvantages: (1), the leather transmission line has a shielding effect on visible light, so sometimes the transmission line may be mistaken for leather during detection and cause false spraying; (2), the use of fluorescent tubes The service life is relatively short, and the replacement cycle is also short, which affects the production efficiency of leather; (3), in the production process, there are other external light sources that interfere with the leather detection device 2, resulting in errors and mistakes in the detection
