Description

Technical Field

[0001] This utility model relates to the field of electrical assembly and adjustment training technology, and in particular to a comprehensive electrical assembly and adjustment training device. Background Technology

[0002] With the rapid development of science and technology, automation technology has been widely applied in various fields, and the demand for automated equipment is increasing daily. In the education sector, automated teaching equipment provides a platform for practical teaching. Relying on the development of information technology, especially the advancement of artificial intelligence, automated teaching equipment can better align its development with the needs of real-world factories. These technological advancements drive the continuous innovation and development of automated teaching equipment, meeting the current talent cultivation requirements of "integrating theory and practice" and promoting the high-quality development of vocational education.

[0003] Chinese patent application number "2018219523372" discloses a new type of electrical assembly and adjustment training platform. This technical solution enables the electrical assembly and adjustment training platform to have a buffering effect, making the electrical assembly and adjustment training platform stable. However, this technical solution only strengthens the buffering effect of the electrical assembly and adjustment training platform, resulting in a large space occupied by the bottom structure of the training platform and a large self-weight of the equipment, making it difficult to move as a teaching equipment.

[0004] Chinese patent application number "2022207326365" discloses a CNC machine tool electrical assembly and adjustment training device. This device uses a servo driver and a frequency converter. The servo driver provides power to the XYZ axis servo motors and controls their speed, torque, and rotation direction. The frequency converter provides power to the spindle motor and controls its speed, torque, and rotation direction. The CNC device is the core of the machine tool's control system. It receives machining information from the CNC program input by the input device, decodes, calculates, and processes the information through its system software or logic circuits, and then sends corresponding pulses to the servo system. This causes the various moving parts of the servo system motor to move according to the predetermined requirements of the CNC program. Furthermore, the rotation rate and direction of the XYZ axis motors and spindle motor can be manually controlled by adjusting the machine tool's operation panel. However, this technical solution only uses a servo driver and frequency converter to adjust the machine tool equipment. This approach is too simplistic for student learning, and the teaching technology is outdated, failing to meet the current comprehensive teaching requirements. Utility Model Content

The perforated plate is provided with wire grooves and is divided into multiple installation areas by the wire grooves. A central control unit, a pneumatic unit, a lighting unit, and a control panel are installed on the perforated plate. The control panel is electrically connected to the central control unit. A three-phase motor is provided on the equipment frame and is electrically connected to the central control unit.

[0008] Furthermore, the central control unit includes a programmable logic controller, a servo drive module, a frequency converter drive module, and a communication module. The perforated board is equipped with a control panel, which is electrically connected to the programmable logic controller.

[0009] Furthermore, the pneumatic unit includes an actuating cylinder, a solenoid valve, and an air pump assembly. The air pump assembly is connected to the slide cylinder and the corner cylinder respectively through an air guide pipe. The solenoid valve is electrically connected to the programmable logic controller and is located on the air guide pipe between the air pump assembly and the actuating cylinder.

[0010] Furthermore, the actuating cylinder includes a rotary cylinder and a slide cylinder, and the air pump assembly is located below the equipment frame.

[0011] Furthermore, the light display unit includes a running light device and a three-color warning light. The running light device is electrically connected to the programmable logic controller, and the three-color warning light is electrically connected to the programmable logic controller to provide intuitive operating status information of the equipment.

[0012] Furthermore, the marquee device comprises a sheet metal frame mounted on a perforated plate and an array of LED lights distributed on the sheet metal frame, for displaying the programming effect of the trainees.

[0013] The beneficial effects of this utility model are as follows: This utility model provides mounting positions for equipment components by installing a perforated plate on a movable equipment rack, which facilitates the installation and debugging of each component. Moreover, this teaching equipment occupies little space and is easy to transport. Through different combinations of the main control unit, pneumatic unit, light display unit, control panel and three-phase motor, it can meet the practical training requirements for the installation and debugging of pneumatic systems, electrical control systems, automatic control systems and electromechanical equipment.
