Control system for loading and unloading manipulator of press

Abstract

The invention relates to a control system for a loading and unloading manipulator of a press based on PID (proportion integration differentiation) control algorithm. Synchronous control of four-shaft alternating-current servo motor and analog input control of eight channels can be realized, movement and coordination of the manipulator and a feeding turntable are controlled according to stamping process flow, products are loaded or unloaded, products to be stamped and not in-place are detected and treated, safety of mechanical equipment is guaranteed, and the control system is flexible in use, sensitive in control reaction, low in program maintenance cost, stable, reliable and applicable to meeting stamping process requirements of other like products.

Description

technical field [0001] The invention belongs to the field of press manipulators, and in particular relates to a control system for press machine loading and unloading manipulators based on a PID control algorithm. Background technique [0002] The press manipulator is a machine specially equipped for stamping automation. It can reduce heavy physical labor, improve working conditions and safe production, and can realize high-speed and efficient loading and unloading through automatic control. [0003] Work plays an extremely important role in improving the production efficiency of presses, stabilizing product quality, reducing scrap rates, reducing production costs, and enhancing the competitiveness of enterprises. [0004] The defects in the control of the manipulator in the prior art are: the manipulator generally uses a single-chip microcomputer as the main control unit. Because the programming work of the single-chip microcomputer is relatively complicated, its internal p...

Problems solved by technology

[0004] The defects in the control of the manipulator in the prior art are: the manipulator generally uses a single-chip microcomputer as the main control unit. Because the programming work of the single-chip microcomputer is relatively complicated, its internal program is solidified and independent. Once a failure occurs or the work task of the manipulator changes, the program needs to be modified. , it needs to be checked by professionals

[0005] The internal program of the single-chip microcomputer is rewritten, and the operation flexibility and versatility of using the single-chip microcomputer to control the manipulator is poor, the cost is high, the program is complex and difficult to develop, and the control accuracy and efficiency are not high

At present, there are also imported and expensive manipulators equipped with CNC servo motors and other systems in China. The manipulator is mainly composed of three parts: positioning, clamping, and turning. However, the price of the equipment is high, and the cost of use is high. Complex structure, low linkage, large volume, difficult maintenance, rotation angle and flexibility need to be improved
