Full-automatic single-ended and double-ended tangent wire stripping terminal pressure welding machine control system

Abstract

The invention discloses a full-automatic single-ended and double-ended tangent wire stripping terminal pressure welding machine control system. The system comprises an industrial computer, a PLC+MC integrated controller and terminal boards. The industrial computer is connected with the PLC+MC integrated controller through a PCI bus interface, and the controller is connected with the terminal boards through DC2 interfaces. The high-performance embedded control technology is introduced to the harness processing field, so that the high-performance control system for harness processing is achieved; coordinated synchronization of mechanical control and mechanical motion is achieved by adopting multiple control modes; the PLC process is integrated with motion control, and high-speed and high-precision smooth processing is achieved through parameter optimization matching of processing technologies, motion control based on speed modes and the like.

Description

technical field [0001] The invention relates to the field of numerical control equipment and wire harness processing equipment manufacturing, and in particular to a control system for a fully automatic crimping machine for single- and double-end wire cutting and stripping terminals. Background technique [0002] Wire harness products are mainly made of metal terminals and wires after crimping and assembly. Although the wire harness processing industry is only a supporting industry, it occupies 1 / 4 of the output value of China's electrical industry. It has a wide range of products and a wide range of applications, involving electric power, construction, communications, manufacturing and other industries, and is closely related to various sectors of the national economy. Wire harness products have been generally considered to have broad development prospects. , The necessary basic products in the information society. [0003] At present, the only countries in the world that ...

Problems solved by technology

[0003] At present, the only countries in the world that can produce such equipment are Germany and Japan. The equipment produced in these countries is very mature in terms of technology and stability, with high added value of technology, and the price of importing them into my country is extremely expensive.

At present, domestic wire harness processing equipment generally has shortcomings such as limited precision and speed, single function, high cost and inconvenient use, mainly in the following aspects:

[0004] 1) The existing terminal machine control systems all use foreign PLCs, which require motor control modules and are expensive;

[0005] 2) The control of the motor is not stable, the start-stop vibration is large, it is easy to overshoot, and the control accuracy is difficult to guarantee;

[0006] 3) The parameter management function is not perfect;

[0007] 4) PLC process control, not suitable for system motor acceleration and deceleration control and closed-loop control;

[0008] 5) Process control logic is not reasonable, it is difficult to improve processing efficiency
