[0002] In the aluminum processing industry, mirror aluminum is widely used in building curtain walls, home appliance shells, automotive interiors and other fields due to its high reflectivity, corrosion resistance and aesthetics. Mirror aluminum has very high requirements for surface quality. However, in the actual processing process, there will be scratches or defects on the surface of mirror aluminum. These scratches or defects will be flattened after being rolled by multiple rollers, forming a defective cortex close to the surface of the aluminum. Since the boundary color of the defective cortex is consistent with the color of the mirror aluminum, it is not easy to be detected or found. These defective cortexes will only be exposed after the customer pickles or deforms the product; and if conventional water washing or roller brushing is used to treat these surface defective cortexes, the glossiness or reflectivity of the mirror aluminum will be affected.

[0008] Furthermore, the viscosity of the film is 45-80 g.

[0009] Another technical solution of the present invention: a method for detecting defects on the surface of mirror aluminum, using the mirror aluminum surface defect detection device as described above, during the process of the aluminum material being transferred from the aluminum material unwinding shaft to the aluminum material winding shaft, the film is transferred from the film winding shaft to the film winding shaft, the aluminum material and the film pass between the upper film coating roller and the lower film coating roller, the upper film coating roller and the lower film coating roller cooperate to press the aluminum material and the film and the aluminum material are bonded together, the film winding shaft tears the film from the aluminum material, and the defective skin layer adhered to the mirror aluminum surface is torn off by the viscosity of the film, and the number of defective skin layers is observed or detected through the torn film.

[0010] Furthermore, the pressure of the upper laminating roller on the film is 2-5 MPa.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the mirror aluminum surface defect detection device of the present invention has a simple structure, is convenient and practical, and has a low investment cost.
