Design of Automatic Feeding-and-Unloading Rotary Manipulator of Punching Machine

In recent years, punching technology of our country is developing fast. The proportion of hand feeding punching processing has gradually been replaced by automatic feeding and unloading mechanism, due to the low efficiency, poor security. In this paper, we design an automatic feeding and unloading system of the punching sheets of motor. The rotary manipulator consists of the transmission device, the mechanical arm device, the material suction device, the raw material automatic lifting device and so on. Adopting the rodless cylinder as the main actuator, the system realizes these beat movements of continuous lifting up, centering, conveying, unloading. According to the working principle and mechanical structure of the components in the system, the function and application of each component in the whole feeding-and-unloading system are analyzed in this paper.

电机冲片模具上下料机械手控制技术与仿真分析

本文主要探究了电机冲片模具上下料机械手控制系统的设计要点,并使用Matlab软件对该系统PID控制器的应用效果进行了仿真分析。上下料机械手控制系统采用S7-200型PLC作为主控制器,配合工件吸附控制模块、气缸伺服控制模块、人机交互模块等,可以自动完成材料的吸取、运移、放置。从仿真情况来看,该系统使用BP神经网络优化后的PID控制器,在运行0.61 s后即可完成调整,稳定性和快速性较好,并且无超调量,对提高上下料机械手的动作执行效果有积极帮助。
