Embodiment Construction
[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0031] Such as figure 1 , 2 Shown, the line speed schematic diagram and the tension control schematic diagram. Compared with the traditional textile detection, a linear speed encoder and a tension control structure are added to the unwinding component, and a tension sensor is added to the winding part to realize the coordinated control of speed and tension. This is based on the fact that lace has high The characteristic of elasticity.
[0032] The control principle of linear speed: V0(t) is the given speed, V(t) is the actual speed, E(t) is the error after the comparison between the two, and the output is sent to the servo drive. After the calculation of the servo motor drive, the pulse is modified Output to the servo motor to correct the linear speed. The encoder acts as a speed feedback device.

The invention belongs to the technical field of textile production, and discloses a nylon lace defect detection device based on machine vision and an application method of the nylon lace defect detection device. The nylon lace defect detection device comprises an uncoiling component (1) and a defect detection component (2), wherein the defect detection component (2) comprises a detection platform(24); the uncoiling component (1) is installed below the detection platform (24); a rolling component (3) is fixedly installed on the back of the detection platform (24); the uncoiling component (1) is electrically connected to a PLC controller; and the PLC controller is electrically connected to the rolling component (3). The method comprises the steps: putting a nylon lace material roll into anuncoiling shaft (13), and enabling the nylon lace material roll to reach a tension control structure (14), and further reach the detection platform (24); judging defects, and starting to roll; and ending operation. The defect detection devices in a textile industry are enriched; and the nylon lace defect detection device is high in detection efficiency and strong in instantaneity.
Description
technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a machine vision-based lace defect detection device and a using method. Background technique [0002] In today's textile industry, flaw detection or defect detection plays a very important role in improving the quality of textiles, and of course lace is no exception. At present, the detection of lace in my country mainly relies on manual detection. The traditional manual inspection method is that inspectors make assessments based on personal experience. This method has many problems such as low detection speed, high missed detection rate, and inconsistent detection standards. Therefore, it is urgent to develop a novel, fast and accurate automatic detection method for fabric defects. [0003] The existing textile defect detection device has the following schemes: (1) Application No. 201820594716.2, name A test bench for textile defect detection, with a tes...
