Embodiment Construction

[0058] In order to better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] refer to figure 1 , in some embodiments, a defect locating system for sheet material slitting is provided, comprising a general controller 101, a defect locating device 102, a slitting device 103 and a rejecting device 104 arranged in sequence along the sheet moving direction;

[0060] The defect locating device 102 is used to detect sheet defects by machine vision and record the length position of the defect, and the slitting device 103 is used to cut the sheet according to the slitting control signal and record each actual cutting length position;

[0061] The controller is configured to calculate the average length of the slice according to the actual cutting length position, and when the defect location device 102 detects a sheet defect, judge the sheet defect accor...

Abstract

The invention discloses a defect positioning system and method for sheet slitting. The system comprises a master controller, a defect positioning device, a slitting device and a removing device, wherein the defect positioning device, the slitting device and the removing device are sequentially arranged in the sheet moving direction; the defect positioning device is used for detecting sheet defects through machine vision and recording the length positions of the defects, and the slitting device is used for cutting sheets according to slitting control signals and recording each actual cutting length position; the controller is used for calculating the tracking distance of the slice where the sheet defect is located to the removing device; the rejecting device is used for executing rejecting operation according to the tracking distance; according to the system, the defect removing device is arranged to remove the defects of the slit sheets, and the defects are accurately positioned by calculating the theoretical optimal cutting position of the sheets, so that the system structure and the operation process are simplified, the omission ratio is reduced, and the material waste is reduced.

Description

technical field [0001] The present invention relates to the technical field of sheet defect positioning, and in particular, to a defect positioning system and method for sheet cutting. Background technique [0002] Slitting machines are widely used in the production of sheets such as paper, film and copper foil. They are mainly used to cut continuous long-length materials into products of different lengths, and play a role in eliminating defects and ensuring product quality. In the actual production process, in order to achieve the purpose of automatically removing defects, the existing slitting machine is usually equipped with machine vision technology for defect detection, that is, an industrial line scan camera is used to scan the object to be inspected, and then the image is processed in real time and analyzed. The type of defects on the surface of the material is determined, and finally the cutting material with the defect area is removed. [0003] However, after the f...
