Ø Composition of practical training and assessment device
The training device consists of an aluminum alloy guide rail training platform, typical mechanical components of mechatronics equipment, PLC modules, frequency converter modules, button modules, power supply modules, simulated production equipment training modules, terminal blocks, various sensors. The overall structure is open and modular. The training device is used for assembling mechanical components; production equipment can be assembled using existing components, or additional components can be added to assemble other production equipment. This allows the entire device to be flexibly assembled into mechatronics equipment with production functions according to teaching or competition requirements. The modules adopt a standard structure and drawer-type module racks, ensuring strong interchangeability. It also requires expandability to form larger-scale production simulation systems to meet the teaching and training requirements of different levels and majors in various user schools.

Ø Equipment Structure
The training device platform is made of aluminum alloy guide rails. The I/O terminals of the PLC module, the wiring terminals of the frequency converter, and the connection terminals of various commonly used modules to the PLC are all connected to safety sockets, using wires with safety plugs for circuit connections. The circuits of various instruction switches, photoelectric switches, sensors, and indicating elements are connected through terminal blocks. The combination of plug-in wire connections and terminal block connections ensures both the training, formation, and consolidation of students' basic skills and the speed, safety, and reliability of circuit connections.

Button module: one set each of 24 V/6 A and 12 V/2 A; 1 emergency stop button, 2 changeover switches, 1 buzzer, 1 reset button each of yellow, green and red, 1 self-locking button each of yellow, green and red, 2 24V indicator lights each of yellow, green and red;
5. Terminal block: The terminal block housing has a primary wiring area (terminal) and a secondary wiring area (safety socket) on opposite sides; the terminal and the corresponding safety socket are connected by a conductive elastic element; the edge of the terminal block housing is rolled up and has screw holes for fixing, so that it can be fixed on the training table.
6. Feeding Mechanism: Feeding Device: A circular feeding tray with a discharge port on the edge; the feeding tray connects to the training table via a frame.
Fixed; a DC geared motor is installed at the bottom of the feeding tray as the rotational power, and is connected to the spiral blades inside the feeding tray through a coupling; one section of the feeding trough is connected to the discharge port. A material platform is installed on the adjusting column, with its height flush with the discharge port, and a photoelectric sensor detects whether there is material.
7. Pneumatic manipulator device: A four-degree-of-freedom pneumatic manipulator, with SMC cylinders and auxiliary sensors; the entire handling mechanism can complete four degrees of freedom movements, including arm raising and lowering, left and right back and forth movement, and clamping and releasing. SMC cylinders and auxiliary sensors are used.
8. Material Sorting Device: The conveyor belt is driven by a three-phase asynchronous motor. A material discharge port is designed at the end of the conveyor belt, and materials are detected by photoelectric sensors. The conveyor belt is equipped with three discharge troughs, with corresponding inductive sensors, fiber optic sensors, etc., and a pushing cylinder is installed directly opposite the trough, for a total of three cylinders. The conveyor belt uses a detachable aluminum alloy frame. SMC is used for the cylinders and auxiliary sensors.
9. Fault testing: The system uses the latest MCU technology RAM processing chip digital integrated circuit board and matching wireless fault setting control system, which is stable and not easily infected by viruses.
The drive module has a built-in intelligent fault setting and control system, and is equipped with a dedicated new wireless data transmission module (pluggable) and an RS232 serial communication interface, enabling wireless networking communication and RS232 wired communication.
Various common faults can be freely set at any point, including open circuits, short circuits to ground, poor contact, and intermittent faults. Each driver module can be configured with 8 high-current (5A) open-circuit faults and 16 low-current (2A) signal path faults (open circuit, poor, intermittent, short circuit, etc.), for a total of 24 fault settings. This can be expanded to include 64 high-current (5A) open-circuit faults and 128 low-current (2A) signal path faults (open circuit, poor, intermittent, short circuit, etc.), for a total of 192 fault settings. The number of fault setting points and the fault setting types can be adjusted according to user requirements.
