Controller for bus-type fully electric injection molding machine

Abstract

The invention discloses a controller for a bus-type fully electric injection molding machine. The controller comprises a human-machine interaction unit and a main control unit; a field bus master station functional module reads instruction data written by an embedded microprocessor from a double-port data memory, packs the instruction data according to the format of a field bus protocol and then outputs the packed instruction data, and the packed instruction data pass through a first network chip and a first network interface and then are transmitted to a slave station; after the slave station processes the instruction data, feedback data are uploaded to the field bus master station functional module from a second network interface and a second network chip; the field bus master station functional module unpacks the uploaded feedback data, and writes the unpacked feedback data into the double-port data memory; and the embedded microprocessor reads the uploaded feedback data from the double-port data memory, submits the feedback data to the human-machine interaction unit for displaying, meanwhile, carries out various control calculations, and writes the calculated control instruction data into the double-port data memory.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine control, and in particular relates to a controller of a bus-type all-electric injection molding machine, which is used for the control of the all-electric injection molding machine. Background technique [0002] In recent years, with the emergence of new synthetic materials, the increasing demand for high-precision injection molded parts, and the enhancement of environmental awareness, people have higher and higher requirements for injection molding machines; all-electric injection molding machines using numerical control technology and high-performance servo drive technology have become It has become the development direction of the global injection molding machine industry and technology; compared with traditional quantitative pump hydraulic injection molding machines, all-electric injection molding machines can save energy by about 70% on average, and their functions and perfor...

Problems solved by technology

[0005] Aiming at the defects of the prior art, the object of the present invention is to provide a controller for a bus-type all-electric injection molding machine, aiming at solving the problem that the existing ordinary injection molding machine controllers can only realize open-loop control by using an analog command interface or a pulse command interface. Or semi-closed-loop control, which seriously affects the control accuracy of the system and the anti-interference ability of analog or pulse command signal is poor, which leads to the problem of low reliability of the system
