Description

Technical Field

[0001] The utility model relates to the technical field of laser rust removal, in particular to a work station and a laser cleaning system. Background Art

[0002] Laser cleaning and rust removal on the surface of steel can be divided into two main modes in terms of movement: the workpiece does not move and the cleaning head moves; the workpiece moves and the cleaning head is fixed. For the cleaning mode in which the workpiece moves and the cleaning head is fixed, the actual application of the project mostly uses roller beds or chain machine pallets to transport the workpieces, and the cleaning heads are mostly fixed on the rack or module. This workpiece moving cleaning movement mode is used for rust removal and cleaning of long profiles, which has high requirements for the site and is greatly restricted by the layout of the production workshop. For the cleaning mode in which the workpiece does not move and the cleaning head moves, in the actual application of the project, a fixed workstation is often used to carry the profile workpiece, and the cleaning head is generally installed with moving parts such as modules, robots, trusses, and ground rails. This cleaning head movement mode is used for rust removal and cleaning of long profiles, takes up little space, and is easy to layout in production. In the mode in which the workpiece does not move and the cleaning head moves, the workstation that carries the profile is often positioned, and the profile is prone to bending and deformation, resulting in poor cleaning effect.

[0003] Therefore, it is necessary to develop a work station that can correct the lateral bending deformation of the workpiece after the workpiece is positioned to improve the cleaning effect. Utility Model Content
