In the emerging industrial era, the automatic production line of automatic machining integrates advanced technologies such as robot technology, PLC technology, sensor detection technology, communication technology and numerical control, realizes the technical combination of industrial robot, loading and unloading manipulator and numerical control machine tool, simplifies the operation mode of numerical control machine tool, improves the operation safety of numerical control machine tool, reduces the labor intensity of workers, and the loading and unloading of workpieces and automatic processing are closely connected, It greatly improves the working efficiency and has good application value.

In order to ensure the cooperation between robot system integration and CNC machine tools, a reliable communication connection between robot, PLC and CNC machine tools is established. In terms of hardware, the corresponding input and output points among the three are connected through shielded cables. In terms of software, the current status of the CNC machine tool and robot is collected through the robot specific software and PLC interface, and the corresponding control program conforming to the loading and unloading logic is compiled to achieve effective communication between the CNC machine tool and the robot.

It is mainly required to handle the emergency stop signal, NC machine tool equipment completion signal, robot gripper pneumatic signal, NC machine tool fixture unclamp signal and safety door signal, and NC machine tool status monitoring screen.

The NC machine tool robot adopts a vision system to reasonably plan the robot's motion trajectory, organically combine the handling technology of industrial robots and the processing technology of NC machine tools, realize automatic assembly line to automatically load and unload workpieces, automatically stack and process finished products, and realize high-precision and low-cost processing of products.

The loading and unloading manipulator of CNC machine tools can meet the requirements of "rapid mass processing rhythm", "improving production efficiency", and become an ideal choice for more and more factories. The loading and unloading robot system of CNC machine tool has high stability, simple structure and easy maintenance, which can meet the production of products with different weights. For users, product adjustment and capacity expansion can be carried out quickly, and the labor intensity of workers can be greatly reduced.
