Abstract

The invention provides a detection system of a PVDF membrane. The system comprises: a light source assembly arranged on a PVDF membrane production line and comprising at least one light source for illuminating a PVDF membrane to be detected; a camera assembly arranged on the PVDF membrane production line and comprising at least one camera for shooting the PVDF membrane to be detected; a marking assembly arranged on a PVDF membrane production line and used for marking a defect position on the PVDF membrane to be detected; a length counter assembly arranged on the PVDF membrane production line and used for detecting the conveying distance of the PVDF membrane to be detected; and a computer respectively connected the light source assembly, the camera assembly, the marking assembly and the length counter assembly, used for triggering the at least one camera based on the conveying distance, detected by the length counter assembly, of the PVDF membrane and an actual production line speed inorder to shoot the PVDF membrane to be detected, and also used for receiving and processing a picture taken by the at least one camera, identifying the defect and controlling the marking assembly to perform code spraying marking on the defect position on the PVDF membrane to be detected. The detection system is suitable for the quality detection of the PVDF membrane, improves the production efficiency and reduces the production cost.

Description

technical field [0001] The invention relates to the technical field of surface defect detection of planar materials, in particular to a PVDF film detection system. Background technique [0002] During the production process of flat sheet, due to many technical factors such as insufficient raw material dissolution, uneven slurry feeding, and rough surface of the roller, there will be particles, cracks, scratches, holes, air bubbles, crystallization, and skin breakdown on the surface. Defects such as layers, stains, pitting, etc., these defects will reduce the quality of the product and increase the difficulty of quality inspection. [0003] PVDF membrane, polyvinylidene fluoride membrane, is a solid support commonly used in Western blotting. It can be divided into: PVDF membranes for water treatment, including ultrafiltration membranes and microfiltration membranes, mainly used for pretreatment of sewage and seawater desalination, etc., to remove impurities such as macromo...
