Fiberglass pultruded sheets are the main raw material for the main or auxiliary beams of wind turbine blades. Internal defects such as voids and dry fibers are major factors affecting the physical properties of pultruded sheets. Simultaneously, with the expansion of domestic pultruded sheet production, blade manufacturers are placing higher demands on the appearance of the pultruded sheet release fabric. Currently, the appearance quality inspection of pultruded sheets is mainly done manually, with one person typically responsible for inspecting multiple machines. However, due to factors such as mood, physical strength, and external interference, a large number of inspections are missed, leading to customer complaints.

A pultruded sheet appearance quality inspection system based on machine vision technology can completely replace manual labor, enabling 24/7 real-time inspection during the pultruded sheet production process. Upon detecting an anomaly, the equipment will issue an audible and visual alarm.

Internal inspection: pores, dry filaments, yarn, lint, and foreign objects of different colors inside the pultruded plate.
Visual inspection: Defects such as stains, poor adhesion, wrinkles, and misalignment on the surface of the release fabric.
