Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass production equipment technology, specifically an edge detection device. Background Technology

[0002] On automated photovoltaic glass production lines, strict quality control is required at every stage, from raw material processing to final delivery of finished products to customers, to ensure product integrity and safety. Particularly during glass processing and subsequent packaging and transportation, meticulous inspection of glass edges is crucial to prevent breakage due to edge defects during production line transport, handling, and long-distance shipping. This can lead to production line shutdowns, environmental pollution, and collateral damage to other intact glass products.

[0003] Edge inspection, a crucial step in this process, is essential for the timely detection and rejection of glass products with edge cracks, chips, or other potential defects. This step not only affects the quality of individual panes of glass but also directly impacts the efficiency of the entire production line and customer satisfaction. To achieve efficient and accurate inspection, inspection cameras are widely used in this stage, capable of quickly capturing subtle changes at the glass edges. However, this also places high demands on the inspection environment.

[0004] Crucially, glass vibration poses a significant challenge to inspection accuracy. On the production line, slight vibrations are inevitable during inspection due to mechanical transmission and environmental vibrations. If this vibration exceeds the depth of field of the inspection camera—typically only about 2 millimeters—it can cause the camera to lose focus, leading to missed detections (failing to identify defective glass) or false alarms (incorrectly marking qualified products as unqualified). Both scenarios negatively impact production efficiency and cost control.

[0005] To address this technical challenge and effectively control costs while ensuring detection accuracy, an innovative edge detection device is proposed. Utility Model Content
