Description

Technical Field

[0001] The utility model belongs to the technical field of laser engraving and cutting machines, and provides a mobile phone steel sheet laser engraving and cutting machine. Background Technique

[0002] Some parts of the mobile phone shell are made of steel sheets. In order to enhance the aesthetics of the steel sheet surface, it is necessary to engrave characters and pattern designs on the steel sheet surface. The pattern designs are used to enhance the aesthetics of the steel sheet, and the characters are used to explain the product parameters and performance. At first, a large steel sheet was divided into multiple small steel sheet areas for laser engraving of characters and pattern designs. After laser engraving, the large steel sheet was cut into several small steel sheets, and then the cut small steel sheets were subjected to post-processing. Usually, a cutting component was added to the laser engraving machine, and cutting was carried out immediately after laser engraving was completed. The working principle mainly involves using the high energy and high density of the laser beam to perform a processing process of evaporating, melting or oxidizing the material, so as to achieve fine engraving and cutting effects. Relying on the laser emitter to generate a high-energy and high-density laser beam, the laser beam is focused into a very small and high-energy-density small light spot through a focusing lens. The adjustment of the size and shape of this light spot determines the accuracy and details of the final engraving effect. The focused laser beam irradiates the material, and the high energy density of the laser causes part of the material surface to be evaporated, vaporized or melted. By controlling the movement of the laser beam through the numerical control system, engraving, carving or cutting can be achieved on the material surface. Since the energy density of the laser beam is very large, a very fine engraving effect can be achieved, and the intelligent adjustment of the control system and the accuracy of the scanning method ensure the accuracy and consistency of engraving.

[0003] During the process of transferring a large steel sheet to the cutting link after laser engraving, due to the different sizes, shapes and engraving positions of the mobile phone steel sheets of different models, after changing the product, the cutting boundaries to be cut are different, and it is necessary to readjust the cutting tool for the cutting boundary on the steel sheet surface. Lacking accurate measurement and positioning measures, it is difficult to accurately determine the cutting boundary, which is not convenient to adjust the position of the cutting tool for cutting the steel sheet, and it is easy to occur cutting misalignment, resulting in defective products.
