With the rapid development of the injection molding industry, there is an increasing demand for higher levels of factory automation The existing fully pneumatic robotic arms and single servo robotic arms for injection molding machines can no longer meet the needs of users well Multi axis servo robotic arms have become a new development direction for injection molding machine robotic arms This article takes the three-axis servo manipulator dedicated to injection molding machines as the research object Design and manufacture a prototype of a three-axis servo robotic arm based on the structural characteristics of the injection molding machine manipulator Using finite element method to analyze and optimize the mechanical arm model, and find the optimal structure
A control system for a three servo robotic arm was developed by combining a touch screen with a motion controller Finite element analysis software was used to analyze the static characteristics, modes, harmonic responses, and transients of a three servo injection molding manipulator. Based on the analysis results, the manipulator was improved and designed to optimize its structure The method for selecting the capacity of servo motors is provided through calculation
The hardware wiring method and parameter adjustment method of the servo motor for the three servo robotic arms under position control mode have been determined The servo motor of the designed three servo robotic arm was debugged on site using servo motor debugging software Through experimental methods, the actual action waveform of the servo motor was extracted and compared, and the motor performance was optimized A human-machine interface for a three servo robotic arm was developed using WEINVIEW's MT8080 touch screen The overall structure of the human-machine interface for the three servo robotic arms has been determined
A detailed analysis was conducted on the development of the core part of the human-machine interface - the teaching function And developed new practical functions for touch screens using macros
