Description

High-efficiency laser engraving device for stainless steel Technical Field The invention belongs to the technical field of laser engraving, and particularly relates to a high-efficiency laser engraving device for stainless steel. Background With the continuous improvement of the requirements of manufacturing industry on precise identification and metal surface treatment, stainless steel materials are widely applied in the field of laser engraving due to the excellent corrosion resistance and aesthetic property. In order to achieve high quality and high efficiency engraving effect, the existing laser engraving technology has been tried in terms of automation degree, machining precision and slag treatment. However, the existing laser engraving device still has certain defects in the aspects of structural compactness, machining efficiency and adaptability to complex working conditions. After searching, a laser engraving machine with an authorized bulletin number of CN110560912B is disclosed, and the authorized bulletin date is 2024, 4 and 5. This patent is through setting up the frame, moving material module and two XY removal modules that are parallel to each other, has realized the two-sided simultaneous processing to the product to processing speed and position accuracy have been promoted. However, in this technical scheme, in order to realize high-efficient processing, adopted extremely complicated mechanical structure, including a plurality of removal modules, layer board, cyclic annular main belt and swage subassembly etc. this not only leads to equipment area big, manufacturing cost is high, and because moving parts is too much, the system maintenance degree of difficulty increases notably. In addition, the complex material moving logic has structural redundancy when processing a single-sided engraving task, and the engraving quality and flexibility are difficult to consider on the premise of simplifying the structure. After searching, a laser engraving machine with an authorized bulletin number of CN118081103B is disclosed, and the authorized bulletin date is 2024, 7 and 5. This patent is to the problem that the metal sheet sculpture in-process produced the slag easily, drives rotatory roller and clearance brush synchronous rotation through setting up drive group two, carries out real-time clearance to the processing region at the sculpture in-process, has avoided the slag to lead to the problem that the nick edge is irregular and the sign definition reduces. However, in this technical scheme, the clearance mechanism (such as rotatory roller, the distributed brush hair of screw thread and the slant board of preventing splashing of slope setting) has increased the sculpture head load and the complexity of moving chain thereof, and in the high-speed sculpture in-process, mechanical contact clearance can produce interference or vibration coupling with the high-frequency movement of laser head, and then has restricted the further promotion of sculpture speed, and the introduction of wearing parts such as brush has also reduced the operational stability of equipment. The above problems indicate that in the process of pursuing processing quality and efficiency, the existing laser engraving device often has the cost of increasing the complexity of the mechanical structure and the maintenance cost, and the consistency of the engraving process and the simplification of the structure still have contradiction.
