Description

Technical Field

[0001] This utility model relates to the field of aluminum processing and manufacturing, and in particular to a device for detecting defects on the surface of mirror-finished aluminum. Background Technology

[0002] In the aluminum processing industry, mirror aluminum is widely used in various fields such as building curtain walls, home appliance casings, and automotive interiors due to its high reflectivity, corrosion resistance, and aesthetics. Mirror aluminum has very high requirements for surface quality. However, during actual processing, scratches or defects may appear on the surface of mirror aluminum. These scratches or defects are flattened after being rolled by multiple rollers, forming a defect skin layer tightly attached to the aluminum surface. Because the boundary color of the defect skin layer is the same as the color of the mirror aluminum, it is not easy to detect or find. These defect skin layers will only be exposed after the customer performs pickling or deformation treatments on the product. However, if conventional water washing or brushing is used to treat these surface defect skin layers, it will affect the gloss or reflectivity of the mirror aluminum. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a simple, convenient and practical, low-cost surface defect detection device for mirror aluminum, which can effectively remove the defect skin layer adhering to the surface of mirror aluminum without affecting the gloss or reflectivity of the mirror aluminum, and facilitate the observation or detection of the number of defect skin layers.

[0004] This utility model is achieved by the following scheme: a mirror aluminum surface defect detection device, including an aluminum material unwinding shaft and an aluminum material rewinding shaft, with an upper coating roller and a lower coating roller provided between the aluminum material unwinding shaft and the aluminum material rewinding shaft for cooperating to press the aluminum material and the film together, a film unwinding shaft provided above the upper coating roller, and a film rewinding shaft provided above and behind the upper coating roller to tear the film from the aluminum material.

[0005] Furthermore, a film flattening roller is provided between the upper coating roller and the film unwinding shaft.

[0006] Furthermore, an aluminum guide roller located on the lower side of the aluminum material is provided in front of the aluminum material winding shaft.

[0007] Furthermore, a film guide roller is provided below the film winding shaft near the upper surface of the aluminum material.

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

[0009] Compared with the prior art, the present invention has the following advantages: The present invention has a simple structure, is convenient and practical, and has low investment cost. By adhering a film to the surface of mirror aluminum and then tearing the film, the defect skin layer adhering to the surface of mirror aluminum is removed by using the adhesiveness of the film. Without affecting the gloss or reflectivity of mirror aluminum, the defect skin layer adhering to the surface of mirror aluminum is effectively removed. Furthermore, the number of defect skin layers can be easily observed or detected by tearing the film.

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below through specific embodiments and related drawings. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model;

[0012] The numbers in the diagram are explained as follows: 100-Aluminum material unwinding roller, 200-Aluminum material rewinding roller, 300-Upper coating roller, 400-Lower coating roller, 500-Film unwinding roller, 600-Film rewinding roller, 700-Film flattening roller, 800-Aluminum material guide roller, 900-Film guide roller. Detailed Implementation

[0013] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0014] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0015] like Figure 1As shown, a surface defect detection device for mirror aluminum includes an aluminum unwinding shaft 100 and an aluminum rewinding shaft 200. An upper coating roller 300 and a lower coating roller 400 are provided between the aluminum unwinding shaft and the aluminum rewinding shaft to cooperate in pressing the aluminum material and the film together. A film unwinding shaft 500 is located above the upper coating roller, and a film rewinding shaft 600 is located above and behind the upper coating roller to tear the film from the aluminum material. This device effectively removes the defect layer adhering to the surface of mirror aluminum by adhering a film to the surface and then tearing the film. The film's adhesiveness removes the defect layer without affecting the gloss or reflectivity of the mirror aluminum. Furthermore, the torn film makes it easier to observe or detect the number of defect layers, facilitating adjustments to the mirror aluminum processing technology and improving the surface quality of the mirror aluminum.

[0016] exist Figure 1 At the observation position, the number of defective skin layers on the film can be observed manually with the naked eye, or visual inspection can be performed using a camera. Visual inspection using a camera is existing technology and is not within the scope of this utility model; therefore, its structure and principle will not be specifically described here.

[0017] In this embodiment, a film flattening roller 700 is provided between the upper coating roller and the film unwinding shaft. The film flattening roller 700 unfolds the film, preventing air bubbles from forming between the film and the aluminum material; during the coating process, the pressure of the upper coating roller 300 on the film is 2-5 MPa, ensuring that the film and the aluminum material can be tightly bonded.

[0018] In this embodiment, an aluminum guide roller 800 is provided in front of the aluminum winding shaft and located on the lower side of the aluminum material.

[0019] In this embodiment, a film guide roller 900 is provided below the film winding shaft, close to the upper surface of the aluminum material.

[0020] In this embodiment, the viscosity of the film is 45-80g.

[0021] The detection method of the mirror aluminum surface defect detection device: During the process of aluminum material being conveyed from the aluminum material unwinding shaft to the aluminum material winding shaft, the film is conveyed from the film winding shaft to the film winding shaft. The aluminum material and the film pass between the upper coating roller and the lower coating roller. The upper coating roller and the lower coating roller work together to press the aluminum material and the film together, so that the film and the aluminum material are bonded together. The film winding shaft tears the film off the aluminum material. The defect skin layer adhering to the mirror aluminum surface is peeled off by using the adhesiveness of the film. The number of defect skin layers can be observed or detected by tearing the film.

Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by integral molding using a casting process) (except where it is obviously impossible to use an integral molding process).

[0024] In addition, unless otherwise stated, the terms used in any of the technical solutions disclosed in this utility model to indicate positional relationships or shapes include states or shapes that are similar to, close to, or approximate with those states or shapes.
