The optimization of the optical software design for injection molding machine dedicated robotic arms can meet the structural design requirements of the robotic arms
When the injection molding machine manipulator used ZEMAX optical design software to optimize the system, in order to better meet the overall structural design requirements of the manipulator system, it underwent repeated testing and optimization. The aperture position is set to overlap with the 9th surface, which can better correct distortion and magnification chromatic aberration due to the overlap between the aperture and the lens. At the same time, it can effectively reduce the diameter of the lens and decrease the size of the system specifications.
After optimizing and shortening the total length of the system, the total structural length of the system at three focal lengths is 330mm, which can meet the requirement of image plane stability. According to the third-order aberration theory, a material was used that cannot correct chromatic aberration, let alone chromatic aberration, and the improvement in image quality was not significant. Therefore, the glass material was replaced on the basis of the original structure, and zinc sulfide was used instead of germanium as the material for the final lens.
The mechanical arm system did not introduce non spherical mirror elements or use diffraction elements, which is beneficial for practical processing and application.
The application of multiple structure commands in ZEMAX design software selects short focus (20mm), medium focus (160mm), and long focus (300) as evaluation criteria, mainly used to evaluate the image quality of the robotic arm system and achieve continuous zoom. Optical system structure. be based on. The above system analysis applied ZEMAX software for a series of optimized designs of the robotic arm system, resulting in the two-dimensional structure of the far-infrared continuous zoom optical system. The application of ZEMAX software for injection molding machine manipulators can optimize the system design, thereby meeting the requirements for stable operation of the manipulator.
