This paper introduces an automatic identification system for a horizontal machining center workbench. The system can automatically identify the workbench, and the CNC system can automatically call the corresponding program for processing according to the identification information, thereby improving the processing efficiency. The system has a simple structure, high reliability, and high degree of automation. While improving the efficiency, it can also avoid manual errors. Due to the high precision and good stability of the laser, it can adapt to the identification of a large number of workbenches.

With the development of my country's economy, it has become a widely accepted consensus to change the labor-intensive, resource-consuming, inefficient and rough production model. The rapid increase in labor costs and the shortage of high-quality labor have also prompted companies to use robots to increase industrial added value and ensure product quality. The desire is much stronger than before. Industrial robots and digital equipment are facing development opportunities, and the degree of automation of machine tools is getting higher and higher with the passage of time.

The machine tool workbench identification structure proposed in this paper includes a protective support structure under the machine tool exchange area, a workbench, an identification block for identification is fixed on the side of the workbench, and a single-lens reflex laser transmitter and receiver is installed on the surface perpendicular to the identification block and the side of the workbench. The laser is sent out to contact the identification block and then returned to be received. The single-lens reflex laser transmitter and receiver can obtain the distance between the remaining identification blocks, and confirm the number of the workbench by the difference in distance. The identification structure is simple, convenient for structural production and installation, can identify a large number of workbenches, can accurately identify the workbench, ensure that the processed workpiece is consistent with the system's processing program, improve the work efficiency of the machine tool, further improve the degree of automation, reduce the processing cost of the workpiece, and can effectively avoid accidents and unnecessary economic losses caused by human errors, which helps to improve the reliability of the production system.
