Research On Multi-size Foam Column Fiber Array Load Micro-assembly System

Since the industrial revolution,petrochemical energy has promoted the gear of the times as the cornerstone of the development of human civilization.However,on the one hand,petrochemical energy has limited reserves,and on the other hand,it has caused damage to nature and human living environment.Therefore,it is being replaced by new energy resources.The research and development of new energy resources refers to using new technologies and new materials to realize modern exploitation and sustainability of resources.Nuclear fusion energy in new energy resources releases a large amount of energy through the mass loss caused by the combination of multiple hydrogen nuclei.It has the advantages of sufficient reserves,huge release of energy,and no radioactivity.The application of Z-pinch inertial confinement fusion in nuclear fusion energy is the most widely used,among which the energy conversion rate of the dynamic black cavity target in the black cavity formed by Z-pinch is the highest,and the target's quality in the nuclear fusion experiment directly affect experiments,it is particularly important to design a semi-automated assembly system to improve the assembly quality of dynamic black cavity targets.In the actual experimental process,the assembled dynamic black cavity target can't be stored for a long time,otherwise it will affect the quality of the foam column;at the same time,the dynamic black cavity target currently required by the experiment contains a variety of specifications,and assembly system requires a higher assembly efficiency and multiple specifications.This paper designed the assembly system from these two points.First,this paper analyzed the composition of the target and the structure of each component,and developed the assembly strategy and assembly process for the task's difficulties.The system assembled with the left and right arms,the ends of the left and right arms were the holders of the target components.The whole assembly process was monitored and controlled visually.After the modular analysis of the platform,this paper designed the overall structure,built model and performed kinematic analysis.The diversity of the system is mainly reflected in the target components: foam columns,foam column bases,and wire array loads all contain a variety of sizes,different specific holders are designed by analyzing the structure and mechanical properties of the target components.The foam column consists of special materials.In order to ensure the non-destructive use of foam columns,this paper used vacuum adsorption clamping;in order to meet the stable clamping of a variety of specifications of the bases and improve the ease of operation,the base used vacuum adsorption and clamping jaws to convert the clamping mode to clamp the form hold.Second,this paper used microscopic vision to achieve precise assembly control.A visual module is constructed through the analysis of the microscopic visual mapping model,and a suitable visual algorithm is used to visually identify the wire array loaded standard rods and bubble columns to control its spatial pose.Finally,a multi-foam column assembly experiment platform was built,and corresponding experimental control software was designed.The reliability of the designed holder was verified by clamping experiments.The bonding and assembly tests were carried out with different specifications of the target components,and the mean value of the bonding accuracy was 0.032 mm and the average assembly accuracy was 0.027 mm,and the assembly requirements were met(0.05mm),demonstrating the effectiveness of the platform.
