Abstract

The present application discloses a primary imaging system and method for laser removal of PVD coatings on terminal shells, wherein the system includes a large field of view image acquisition module, a lens, a light source assembly, and a filter assembly; the light source assembly includes a first monochromatic light source . The second monochromatic light source; the filter assembly includes a first band-pass filter and a second band-pass filter integrally connected. Compared with the existing technology, the large field of view image acquisition module is adopted, which can satisfy the enough field of view to realize one-time imaging while ensuring the system pixel equivalent, and improve the accuracy and efficiency of the system. The light source adopts the combination of two kinds of monochromatic light sources. At the same time, the combination of filters with the opposite color to the light source is set in front of the lens to prevent the strong light in the reflected light from entering the lens, and only keep the weak reflected light in the reflected light to enter the lens. Solve the problem of image overexposure on the edge of the arc surface of the terminal shell, and the image is clearer, so that the laser positioning software can perform high-precision positioning of the target (the position where the PVD coating needs to be removed).

Description

Technical field[0001]The present application relates to the field of visual imaging, and more particularly to a primary imaging system and method for laser removal of the terminal housing PVD plating layer.Background technique[0002]The coating obtained by PVD (Physical Vapor Deposition, Physical Vapor Deposition) technology has the advantages of high hardness, low friction coefficient, good wear resistance and chemical stability, which is widely used in the manufacture of terminal equipment, such as mobile phones. Shell, tablet case, etc. The raw material metal in the general PVD plating is a well conductor. If it is applied to the entire mobile phone case, electromagnetic shielding occurs, causing the mobile phone signal to be deteriorated or even unable to receive data. Therefore, it is necessary to open a slit on the phone case, the next antenna, remove the PVD plating layer, change to plastic fillers to enhance the signal overflow.[0003]Usually, such asfigure 1 As shown, accordi...
