Abstract

The invention discloses a flexible PCB electromagnetic micromirror, a scanner and a laser marking / carving machine. The flexible PCB electromagnetic micromirror comprises a flexible PCB structure, a lens and external magnets; the flexible PCB structure comprises a flexible layer and a coil layer, and the flexible layer is usually a polyimide layer; the lens is adhered to the flexible PCB structure;the external magnets are arranged around the flexible PCB structure and are used for generating a magnetic field; and during being used, voltage / current is applied to a coil of the coil layer, and the coil perpendicular to the magnetic field generates force for driving the flexible PCB structure and the lens to rotate. The flexible PCB electromagnetic micromirror has the characteristics of beinglarge in quasi-static rotation angle, large in optical aperture, high in lens surface flatness and low in cost; the laser scanner can be manufactured on the basis of the flexible PCB electromagnetic micromirror, and the laser marking / carving machine can be manufactured on the basis of the laser scanner; and the marking / carving machine has the advantages of being low in cost, convenient to carry and the like.

Description

technical field [0001] The invention relates to the technical fields of micromirror and laser marking / engraving, in particular to a flexible PCB electromagnetic micromirror, a scanner and a laser marking / engraving machine. Background technique [0002] Laser marking / engraving machines use a focused laser beam to remove top layers or alter the surface properties of target materials. They are widely used in marking / engraving identification numbers, logos and barcodes etc. in industries such as automotive, medical equipment, textile, electronics and semiconductor. Compared with other marking technologies (such as electrochemical etching, dot impact and inkjet), laser marking technology has many advantages, such as: can eliminate burrs and waviness to obtain higher surface quality of the finished product, non-contact method, and can Mark on materials that are difficult to mark with other techniques. A laser marking / engraving machine consists of two main parts: a laser source a...
