The conveying mechanism detects the product transmission distance through the conveyor belt, meter wheel and incremental rotary encoder. The code scanning mechanism uses the first and second code scanning cameras to identify the QR codes on the back and front of the product respectively. The sealing detection mechanism detects the product's sealing quality through the sealing camera.

Benefits of technology

It realizes scanning of QR codes on both sides of the front and back without flipping of FOG products of different specifications and inspecting the quality of the sealant on both sides without flipping, avoiding secondary damage to the product during flipping, improving detection efficiency, and using software to set distance parameters to adapt to products of different specifications, simplifying the debugging process of the camera and light source.

Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and in particular to a vision-based integrated code scanning and sealing detection device. Background Art

[0002] Flexible On Glass (FOG) means directly binding the flexible circuit board to the electrode at the edge of the liquid crystal glass. The process flow of automotive FOG products requires the binding parts to be sealed with glue. However, during the sealing process, due to mechanical vibration or accidental errors, various defects such as no sealing, broken glue, and lack of glue may occur. Generally, FOG products will print QR codes for product traceability. However, the QR code pasting position will be posted in different positions due to the specifications of the product, or even posted on both sides of the front. In the actual production process, the traditional manual inspection method requires scanning and sealing inspection of the product separately, which is inefficient and easy to fatigue. The robot or transmission belt inspection equipment also needs to repeatedly flip the product for scanning and sealing inspection. The position of the camera and light source needs to be repeatedly adjusted for products of different specifications and sizes. Utility Model Content
