Technical Field

[0001] This utility model relates to the field of keycap manufacturing technology, and in particular to a keycap manufacturing defect re-inspection device. Background Technology

[0002] In the keyboard manufacturing process, keycaps, as a crucial component for human-computer interaction, directly impact the overall quality of the product and the user experience. After processes such as painting and printing, keycaps often suffer from issues such as misprinted characters, missing characters, blurry images, uneven paint application, abnormal light transmission, and structural defects like rough edges and deformation.
