Description

Technical Field

[0001] The utility model relates to the technical field of notebook shells, in particular to a device for detecting surface defects of notebook shells. Background Art

[0002] Laptops, also known as "portable computers, handheld computers, PDAs, or laptops," are distinguished by their compact size and portability compared to PCs. To ensure strict quality control, notebook casings are inspected for surface defects during the factory process. Unqualified products are rejected to ensure a high pass rate for all notebook casings.

[0003] In this regard, the Chinese utility model patent with authorization announcement number CN216900255U discloses an AI appearance inspection device for a notebook computer shell, which relates to the field of visual inspection technology, including a box body, a light-shielding window fixedly connected to the side of the box body, a placement table fixedly installed on the inner surface of the box body, a hanging table fixedly installed on the inner surface of the box body, a spring fixedly connected to the side of the hanging table, a fixing plate fixedly installed on the upper surface of the spring, a fixing rod fixedly connected to the side of the fixing plate, and a socket provided on the surface of the hanging table. In actual use, when people need to maintain or replace the detection light mirror, the fixing plate is pulled outward so that the fixing rod moves outward with the fixing plate, and the spring gradually stretches with the fixing plate. When people move the fixing rod to the outside of the socket, the detection light mirror can be removed, which is convenient for people to maintain or replace the detection light mirror. The disassembly process is simple and convenient, which is conducive to actual use.
