Laser processing device

Abstract

The present disclosure discloses a laser processing device, which includes a casing and a flexible light-blocking structure. An inner cavity is formed within the casing. The outer side wall of the casing is provided with a material passage communicating with the inner cavity for materials to enter and exit the inner cavity. The flexible light-blocking structure is positioned within the material passage to block the material passage, preventing light within the inner cavity from transmitting outward. The flexible light-blocking structure is further configured to deform when materials enter or exit the material passage, creating a gap between the flexible light-blocking structure and the material passage for the materials to pass through.

Dependencies are inferred from the claim text.
