Description

Technical Field

[0001] The utility model relates to the technical field of linear array scanning platforms, in particular to a time-sharing stroboscopic experimental platform. Background Art

[0002] Time-sharing stroboscopic test benches are primarily used in industrial inspection applications, such as detecting scratches, bumps, dirt, and chipped edges on mobile phone glass screens. These inspection tasks are difficult to address with a single vision solution, and using multiple inspection stations for separate inspections can be challenging due to space and cost constraints. However, time-sharing stroboscopic technology can improve inspection efficiency while reducing equipment space and costs. Existing time-sharing stroboscopic test benches typically use fixed positions and angles for their line scan cameras and linear light sources. While this is sufficient for most inspections, testing parts with unusual shapes requires unconventional angles for more efficient inspection. Utility Model Content
