The Beam Path Design Of The Online Laser Perforating System

Laser perforating system in scanning is widely used to perforate some thin nonmetal material, such as paper, leather and plaster, and so on. The system has many advantages, including simple and reliable control structure, high efficiency, dense and tidy pores after perforating. The principle and implement of a new type wide range laser perforating system is introduced in this article, the system is highly improved in perforating range and numbers and can be compatible with manufacturing facilities online.First of all, the beam path design, which is mainly about how to design this system according to the theory and practical requirement. Using the method of light splitting and the scanning unit, the system transfers CW laser into pulses to increase the perforating range and efficiency. It researchs the scan principle of prism and parabolic reflector,and optimizes the parameters of scanning system to reduce the distortion and ensure the practical scanning range. Through comparing implements of focus,it chooses a proper one and estimate the focus spot diameter for perforating.Then, the experiment equipment, which discusses the practical problems and solutions. It includes the material, processing standard and the mechanical parts design of optiacal element. It also induces the controlling parameter for perforating,from which we design the control system.At last, the experiment, which includes the installation and alignment of the equipment and analyzing the result. The result of experiment proves that the perforating effect are excellent and fits well with the theoretical analyzing.
