Problems solved by technology

Other lasers commonly used in existing laser marking technology are 1-micron fiber lasers and neodymium-doped stone (YAG) solid-state lasers. The laser wavelengths emitted by these lasers are 1.01 to 1.15 microns. These wavelengths of laser light can pass through glass and transparent plastics, etc. Packaging materials, however, for the capsule pharmaceutical materials to be processed, since these capsules are transparent or translucent materials composed of organic components, the above-mentioned 1 micron wavelength laser cannot perform laser marking on these organic objects
Therefore, the concept of laser marking the capsule organic material to be processed through transparent or translucent packaging materials is difficult to achieve with the existing laser marking technology.

Abstract

The invention discloses a laser marking method for a capsule. The laser marking method is characterized in that transparent or semi-transparent materials are used for packing and locating the capsule to be marked, a laser beam is focused on capsule materials to be processed through a transparent or semi-transparent package layer for laser marking, and the wavelength of the laser beam is 1.5 micrometers to 2.5 micrometers. The laser marking method realizes laser marking on capsule materials containing organic materials in an outer package layer packaging protection state, can realize automatic marking classification of mini-sized capsule medicines, and can realize large-scale industrialized production.

Description

technical field [0001] The invention relates to a laser marking method, in particular to a method for laser marking on the surface of a capsule, which belongs to the field of laser material processing. Background technique [0002] The processing of materials by laser is an important processing technology in the fields of modern industry, medical equipment and high-end equipment manufacturing. For example, laser marking is not only clear and wear-resistant, but also does not require ink materials, which is very conducive to environmental protection, and can realize large-scale high-speed industrialized automated production. [0003] There are a large number of capsule drug packages in the field of pharmaceutical materials. Marking and identifying the model numbers of these capsule drugs can scientifically and clearly classify capsule drugs, which is of great significance to drug safety management and use. Traditionally, ink printing, spraying and other methods are used to p...
