Abstract

A method and device (100) for optically processing the surface of a casing, the method comprising: a laser engraving machine emits a first light beam (130) and a second light beam (140); the first light beam (130) passes through the light The first light-transmitting area of ​​the mask (110) is transmitted to the first bonding surface (150) of the casing to perform laser engraving on the first bonding surface (150); the second light beam (140) passes through the The second light-transmitting area of ​​the photomask (110) is transmitted to the light-reflecting module (120); the light-reflecting module (120) reflects the second light beam (140) to the second bonding surface (160) of the casing, so as to Laser engraving is performed on the second bonding surface (160), wherein an included angle exists between the first bonding surface (150) and the second bonding surface (160). By adopting the method and device (100) for optically processing the surface of a housing, laser engraving can be performed simultaneously on the bottom surface and the side surface of the terminal equipment housing.

Description

technical field [0001] The invention relates to the technical field of surface treatment of shells, in particular to a method and device for optically treating the surface of a shell in the technical field of surface treatment. Background technique [0002] The peeling off of the display screen is one of the common problems in the use of terminal equipment with a display screen. The adhesion between the terminal equipment cover and the display screen is an important factor determining the quality of the terminal equipment. In the terminal equipment assembly process, the surface treatment of the terminal equipment shell is usually carried out to increase the roughness and specific surface area of ​​the terminal equipment shell, thereby increasing the bonding area of ​​the glue between the terminal equipment shell and the display screen, which can make The glue bond is stronger. [0003] Carrying out laser engraving on the shell of the terminal equipment is an existing common...
