AI Technical Summary
Traditional laser cleaning heads cannot effectively cover the inner wall of the internal cavity structure. The need to rotate the workpiece leads to complex equipment, cumbersome operation and low efficiency. At the same time, the cleaning of the inner wall causes serious dust pollution and damages expensive optical components.
A hollow motor drives the reflector to rotate at high speed to form a dynamic annular light spot. Combined with an adjustable focusing lens module and a coaxial protective air circuit design, it achieves efficient internal wall cleaning without rotating the workpiece, and isolates smoke and dust from optical components through the coaxial protective air circuit.
It achieves efficient and simplified equipment operation by cleaning the inner wall at 360°, reduces the risk of optical component contamination, improves equipment stability and service life, and reduces maintenance costs.
