Stamping System with Automated Feeding Based on Programmable Logic Controller Electronic Cam Function

Abstract

Products in the stamping industry have been widely used in 3C products (computers, communications, and consumer electronics), daily necessities, and transportation vehicles. With the rapid development of the manufacturing industry and the rising cost of traditional methods of production, labor, equipment, and materials, it is essential to invest in automated production equipment. Therefore, improvements in stamping equipment with automated feeding to increase production capacity have been valued and adopted by enterprises. Manufacturers have also invested in the development and production of stamping equipment. The main purpose of this study is to improve the stamping process to reduce labor and increase production capacity. First, a 3D feeding manipulator is simulated. Its control system adopts a programmable logic controller with a motion control module, which is then connected to a servo unit via Mechatrolink-III on-site network communication. An electronic cam synchronous tracking function is used to control the trajectory between the manipulator and the punch and reduce the punch’s waiting time for the displacement of the manual parts of the feeding machine, thereby increasing the production efficiency. The control system is matched with a human-machine interface, which makes it easier to operate, test the mold, set the cam curve, and troubleshoot. Thus, product quality and production capacity can be significantly improved.
