TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The laser system further includes a galvanometer scanning mechanism. The galvanometer scanning mechanism is connected with a plastic body electric beam. The galvanometer scanning mechanism is provided between the beam shaping mechanism and the pole piece. The galvanometer scanning mechanism and the pole piece are further provided with a focus lens. The cleaning device further includes an auxiliary platform. The auxiliary platform is provided below the laser system. The auxiliary platform comprises an adsorption cooling mechanism for fixing and cooling pole pieces. The adsorption cooling mechanism and the laser emission head are provided on both sides of the pole piece. The auxiliary platform further comprises a dust removing mechanism for gettering coated granules produced in the laser cleaning process. The dust removing mechanism is disposed between the pole piece and the laser system. The cleaning device further includes a central control system. The central control system is connected with the transmission system. The laser system is electrically connected to the auxiliary platform. The transmission system comprises at least one supply roll, a take-up reel and multiple fixed rollers. One end of the pole piece is connected with the supply roll and the other end is wound on the take-up reel by fixed roller. The transmission system further comprises at least one sensor for locating a pole piece area to be cleaned. The sensor is provided between the supply roll and the auxiliary platform. A pole piece rectifying mechanical device is further provided between the supply roll and the sensor. The transmission system comprises at least one sticky dust mechanism for removing residual particles and impurities upper pole piece. The sticky dust mechanism is disposed between the take-up reel and the auxiliary platform. The cleaning device further includes a quality monitoring system for detecting the pole piece after cleaning. The quality monitoring system is disposed between the sticky dust mechanism and the take-up reel. The quality control system is electrically connected to the central control system. The transmission system further comprises at least one guide roller for front and back flipping the pole piece. The device is provided with two laser systems and auxiliary platforms. One of the laser system is corresponds to a front of the pole piece and the other laser system is corresponds to opposite pole piece.
