Problems solved by technology

[0006] For non-continuous film products that are arranged on the continuous film roll carrier at intervals, if the conventional detection equipment for continuous film rolls is used, the film product will often be warped or sunken due to the uneven tension of the film roll, which will cause varying degrees of damage. It will cause the distortion of the image acquisition of the membrane product, and cause the misjudgment of the defect of the membrane product

Abstract

The invention aims to provide surface defect detection equipment based on machine vision, which is used for surface defect detection of a film roll and comprises a rack, a film roll assembly and a vision detection system, the rack comprises an operation table, a side bracket and an upper frame, and the operation table comprises a detection area; the film roll winding comprises a feeding roll shaft, a release paper collecting roll shaft, a tightening roll shaft, a release paper feeding roll shaft and a discharging roll shaft which are connected in sequence. The visual detection system comprisesan industrial camera, a light source and a PLC. The visual detection system is installed on the rack through a system support and arranged above the detection area, after a product enters the detection area, the PLC sends a camera trigger signal to take a picture, and after picture taking analysis processing of the camera, the PLC controls an executing mechanism to act. According to the method, the position of the defect area can be quickly and efficiently found and found as soon as possible, and defect films can be treated from the source.

Description

technical field [0001] A method and device for detecting defects in discontinuous lithium battery thin films based on machine vision. [0002] Technical field [0003] The invention relates to the technical field of machine vision, and mainly relates to surface defect detection equipment based on machine vision for online detection of surface defects of film roll products. Background technique [0004] The traditional film surface quality inspection is realized by manual online visual inspection and offline finished product sampling inspection, which is only suitable for small-scale production occasions. Manual detection uses subjective impression as the detection standard, and it is difficult to achieve the consistency of detection between different products in the horizontal direction and at different times in the vertical direction. In addition, it is limited by the detection speed and sampling frequency, as well as the human visual sensitivity and resolution. The produ...
