Technical Field

[0002] Aluminum hose is a common packaging material. Because it has relatively high sealing, antioxidant and corrosion resistance, and can effectively isolate oxygen, odor, sunlight, ultraviolet rays, and is non-toxic and odorless, it is widely used in ointments, cosmetics and other industries.

[0003] After processing, aluminum hoses often have large defects on their surfaces. Due to the shiny surface of aluminum hoses, it is not convenient to observe these defects with the naked eye. Infrared detectors are usually used for detection. However, because the side of the aluminum hose is a circular arc, the detection end of the infrared detector has a small coverage area, making it difficult to quickly and comprehensively cover the surface of the workpiece. This results in low detection efficiency and slow speed, inaccurate detection, and easy omissions.

[0004] Therefore, in view of the defects of the above-mentioned aluminum hose surface defect detection device, because the side of the aluminum hose is a circular arc surface, the detection end of the infrared detector has a small coverage area, and it is difficult to quickly and comprehensively cover the surface of the workpiece. As a result, the detection efficiency of the device is low, the speed is slow, and the detection is inaccurate, and it is easy to miss the detection. This urgently needs to be solved to improve the use scenario of the aluminum hose surface defect detection device. Utility Model Content
