Description

Technical Field

[0001] The utility model relates to the technical field of PVB film production, in particular to a heat-insulating PVB film defect detection device. Background Art

[0002] PVB (polyvinyl acetate butyrate) is a polymer material commonly used in the manufacture of laminated glass. Laminated glass has high strength and heat insulation effect. The strength and heat insulation effect of laminated glass are closely related to the quality of the PVB film in the middle. Therefore, when producing PVB film, it is very necessary to detect defects on the surface of PVB film.

[0003] Nowadays, defect detection of PVB film is mostly done by staff using a handheld light source to illuminate the PVB film and then observe it. This detection method will not only affect the defect detection effect due to different irradiation angles or limited irradiation ranges, but is also very inconvenient to operate. It is only applicable to the detection of smaller PVB film samples. In the actual production and processing process, PVB films are mostly stored in rolls. When defect detection is required, they are unrolled and transported by winding rollers. The manual handheld optical irradiation method cannot meet the normal defect detection needs. Therefore, a defect detection device for heat-insulating PVB film is urgently needed. Utility Model Content
