PCB Production Line Layout Analysis And Blister Box Grabbing Manipulator Design Research

Printed circuit board(PCB)is an important part of the electronic products.In order to reduce labor input,improve production efficiency and product quality.In this paper,the automatic transformation of the PCB production line is carried out according to the production demand of PCB.The design of the manipulator used to grab the plastic box for PCB packaging production line was completed.The manipulator can complete the automatic grasping,packing and stacking of the plastic box.According to the technical requirements and working parameters in the actual production of PCB,the layout of the PCB production line and the plastic box grasping manipulator are analyzed and studied in detail.The main work of this article is as follows:(1)Make a detail research for the layout of the production line and the manipulator.Understand the layout and balance analysis method of production line and the structural form of the manipulator for packaging production line.The research goal of this paper is put forward in combination with the actual production of PCB.(2)Carry on the automatic transformation to the original production line and the process flow of PCB production line is analyzed.Based on Petri network,a process model of PCB production line is set up to prove the feasibility of the scheme.At the same time,the improvement measures are put forward in view of the balance problem of PCB production line.The balance rate and the system smoothness of the production line are improved.(3)After analysis and calculation,the basic parameters such as the number of degrees of freedom and the working space of the mechanical hand are determined.The design scheme of the manipulator is determined according to the parameters.According to the working conditions and design requirements,the selection and calculation of key components,such as motor and guide rail,are completed.The assembly of all parts was assembled by Pro/E software,and the assembly structure of the manipulator that grasp the plastic box for loading PCB was obtained.(4)The grasping mode suitable for the PCB loading box is determined,and the structure of the end-effector is designed.The calculation of the clamping force of the fingertip is calculated and the static analysis of the plastic box is carried out by Pro/M software.The driving force range of the plastic box grabbing end-effector is given.(5)The required number and type of pneumatic components is determined according to the plastic box grasping manipulator pneumatic loop work demand.The simulation model of pneumatic circuit is established by Fluidsim-P software.The work sequence is optimized under the condition that the motion of each device did not produce interference.
