• SMD (surface mounted devices) generally needs to be accurately and nondestructive installed on the special carrier belt made of PVC plastic sheet for users, or for the automatic installation production line of components.

At present, there are more and more electronic products using surface mount technology, and SMD tape forming machine is an indispensable equipment in the production of surface mount electronic components. The automation level of SMD belt carrying forming machine will play a decisive role in the output and quality of belt carrying. –Carrier Tape Used for SMD Package

Therefore, the development of SMD belt carrying forming machine has important engineering practical value and practical significance. The purpose of this research is to design a SMD belt carrier forming machine integrating machinery, electricity and gas. –Carrier Tape Used for SMD Package

HMI (human machine interface, also known as touch screen) is used to realize man-machine dialogue, PLC (programmable logic controller) is used as the control core of the system, servo amplifier, permanent magnet synchronous motor and encoder are used to form a speed closed-loop control system, and relay control system is combined with computer technology, Realize the full-automatic control of SMD belt carrying forming machine. —Carrier Tape Used for SMD Package

The main research contents of this paper include the following aspects:

firstly, a new design using permanent magnet synchronous motor as the main drive of SMD belt forming machine is proposed to complete the hardware design of the system. It solves the problems of low product precision and low output caused by using the cylinder stop as the belt drawing power of SMD belt loading forming machine.

Secondly, the control schemes of various permanent magnet synchronous motors are analyzed and compared, the servo motion control system based on PLC is selected, and the software and hardware design of the control system is completed.

Finally, PLC and HMI man-machine interface programs are designed, which can guide and monitor the operation of the whole control system, facilitate the operator to set and save the control parameters corresponding to different specifications of materials on the touch screen, display various equipment fault information and solutions, make the operation more convenient, and greatly save the debugging time of fault handling and changing specifications and varieties, Meet the requirements of modern SMD belt carrying forming machine.
