Overview

 

Circular ingredient optical and electrical experimental desk is based on type material guide r--l tr--ning table, typical mechanical components, PLC modules, inverter modules, button modules, power modules, simulation production equipment tr--ning modules (including the above material unit, belt belt, belt, belt, belt, belt, belt, belt, belt, belt belt, belt belt, belt belt, belt belt, belt belt Transfer detection units, pneumatic robot handling units, material transmission storage units, and return units), touch screen, wiring terminal row, and various types. The open and disassembly structure is adopted, and production equipment can be assembled according to the existing mechanical parts, so that the entire device can be flexibly assembled by tr--ning or competition to assemble the optical and electrical integrated equipment with production functions. The module adopts industrial standard structure and drawer module placing frame, which has strong interchangeability.

The tr--ning system integrates motion control, pneumatic control, step motor driver, servo motor driver, sensor detection, programmable control, timing logic control. Based on the use, tr--ning and tr--ning based on the tr--ning system, we can fully exercise the operator team collaboration ability, planning organization ability, automatic line installation and debugging capabilities, and engineering implementation capabilities. At the same time, it is suitable for students to design and graduate design.
