The invention relates to the technical field of laser, and particularly discloses a device and method for removing a PVD coating film through ultrafast laser. The top of the supporting seat is fixedly connected with a supporting rod; the top of the supporting rod is fixedly connected with a top plate; a laser assembly is arranged at the bottom of the top plate; the top of the supporting seat is fixedly connected with a pair of straight plates; cylindrical blocks are rotationally connected to the outer side walls of the pair of straight plates; clamping blocks are fixedly connected to the side walls, away from the straight plate, of the pair of cylindrical blocks. A first motor is mounted on the outer side wall of the straight plate; the output end of the first motor is fixedly connected with a rotating shaft; a first straight gear is fixedly connected to the outer side wall of the cylindrical block; the outer side wall, close to the first straight gear, of the rotating shaft is fixedly connected with a second straight gear engaged with the first straight gear. A fixing mechanism is arranged in the pair of clamping blocks; and the workpiece is clamped through the fixing mechanism, so that the workpiece is kept stable after being overturned, and a PVD film layer on the surface of the workpiece is conveniently removed.
Description
technical field [0001] The invention relates to the field of laser technology, in particular to an ultrafast laser removing PVD coating device and a method thereof. Background technique [0002] During the processing of the part, in order to meet the service of the part under specific conditions, the surface of the part needs to be coated with a coating. PVD coating is a film coated on the outside of the part. In the process, there will be defective products, so it is necessary to strip the parts. In order not to damage the parts, most of them use laser cleaning and stripping to achieve stripping treatment of the parts. [0003] In the prior art, when the laser removes the PVD film layers on different sides of the workpiece, it is necessary to manually turn the workpiece over to facilitate the laser to remove the PVD film layers on the different sides of the workpiece. The temperature is high, and there is a possibility of being scalded by manually turning the workpiece. ...
