High-speed spectroscopic application galvanometer motor

Abstract

The invention discloses a high-speed spectroscopic application galvanometer motor. The high-speed spectroscopic application galvanometer motor comprises a stator, a rotor relatively rotated with the stator and a digital grating feedback encoder located at one end of the rotor, the stator comprises a coil sleeve and a coil located in the coil sleeve, the coil sleeve is formed by whole turning of permeability magnetic materials, and the coil is glued and fixed with the coil sleeve by pouring sealant; the rotor comprises a cylindrical permanent magnet rotationally installed in the coil, and two ends of the cylindrical permanent magnet are respectively fixedly provided with first stainless and second stainless. The spectroscope is directly glued on a lens clamp through glue, the whole structure is compact, the rigidity is high, the response speed is fast, and a digital optical grating feedback encoder capable of real-time and rapid synchronous feedback of the motor angle and position is employed to greatly improve the position precision and repeat location precision of the galvanometer motor.

Description

Technical field [0001] The invention relates to a galvanometer motor for high-speed spectroscopy applications, in particular to a moving magnet type galvanometer motor for high-speed spectroscopy applications that can be used in laser welding spectroscopic equipment or similar systems. Background technique [0002] Most laser welding machines are single-station, and one laser can only be provided for one workbench. At present, welding lasers are mainly imported machines. The price is high and the use of each laser requires a series of peripheral equipment. Including the cabinet power control card, it occupies a large area, but the laser welding time is short and the interval is long in one station on the production line, and the actual use efficiency of the laser is relatively low. The use of galvanometer motors for high-speed spectroscopy applications greatly improves the efficiency of lasers, reduces production costs, and saves production space. Galvanometer motors for high-spe...

[0002] Most of the laser welding machines are single-station. One laser can only be used for one workbench. At present, welding lasers are mainly imported machines, which are expensive and each laser requires a series of supporting equipment. It includes a cabinet power control card and occupies a large area. However, a station on the production line uses a laser for short welding time and long intervals, and the actual use efficiency of the laser is relatively low.
