V1.0 Shanghai Empower Technologies Co., Ltd. © Copy Right 5 | 24www.empower.cnBM109 SERIES 1.5KW Auto-Focusing Laser Cutting HeadsUser Manual Maximum acceleration of focus lens driver 10m / s2, maximum speed 6m / min; The drawer type lens holder makes the replacement of protective lens more quickly andeasier The composite lenses were used for collimation and focusing to obtain the best opticalquality and cutting effect; With QBH interface, can be adapted with various fiber lasers.1.2 Structure & FunctionAs shown in Figure 1, the laser head consists of five basic units, such as collimated water-cooledmodule, collimation centering module, focus drive module, protective lens module, nozzle module. Collimated water-cooled module: complete the function of cooled collimating module, water-cool the collimation centering module; collimation centering module: complete the function of fiber collimation, collimate incident laserinto parallel beams with centering function; Focus drive module: focus the collimated beam to a high power density convergent beam andrealize automatic adjustment of the focus position by the driving device; Protective lens module: protecting lens can protect focusing lens from the damage of return slagsand extend the life of focusing lens; Nozzle module: guide beams to the processing workpiece and produce high-speed air jet joint-cutting to achieve high-quality cutting.
