Embodiment 1

[0026] A control system for dispensing valves controlled by voice coil motors, including FPGA (Field Programmable Gate Array) components, FPGA components are electrically connected to voice coil motors and domestic dispensing valves, and the voltage of the PWM signal generated by the voice coil motor is 48V , use the optocoupler to step down to 5V, because the driving voltage of FPGA components is 3.3V, and can withstand 5V voltage, it can be compatible with domestic dispensing valves, reducing equipment costs, taking advantage of the advantages of parallel processing of FPGA components, and portability powerful. The injection valve of the existing Camalot FX-D dispensing valve control system is controlled by a voice coil motor. The injection valve system is divided into four parts, namely: voice coil motor, encoder, and dispensing of Camalot FX-D Valves and ASICs (Application Specific Integrated Chips). The internal signal transformation of the existing Camalot FX-D dispensi...

Abstract

The invention discloses a control system and a control method for a dispensing valve controlled by a voice coil motor, and aims to solve problems in the application of the existing domestic dispensing valve. The invention includes FPGA (Field Programmable Gate Array) components, and the FPGA components are respectively electrically connected with voice coil motors and domestic dispensing valves. The invention is compatible with domestic dispensing valves, solves the problem that domestic dispensing valves cannot be used for normal dispensing on Camalot equipment, reduces equipment costs, and ensures normal dispensing; the invention uses FPGA components with strong portability, which can be used many times Burning greatly improves the designer's ability to meet the needs of customers. The dispensing effect of the present invention can be comparable to that of the world's leading imported dispensing valve system, and the application prospect is broad.

Description

technical field [0001] The invention relates to the field of voice coil motors, in particular to a control system for controlling a dispensing valve by a voice coil motor. Background technique [0002] In recent years, with the improvement of performance requirements for high-speed and high-precision positioning systems and the rapid development of voice coil motor technology, voice coil motors are not only widely used in precision positioning systems such as magnetic disks and laser disc positioning, but also in many different forms of high acceleration, It is also widely used in high frequency excitation. [0003] Voice coil motor (Voice Coil Motor) is a special form of direct drive motor. It has the characteristics of simple structure, small size, high speed, high acceleration and fast response. Its working principle is that when the energized coil (conductor) is placed in the magnetic field, a force will be generated, and the magnitude of the force is proportional to t...
