JZ-20B Mechanical Manufacturing Engineering Display Cabinet (Touch Screen Control)

1、 Overview:
The "Mechanical Manufacturing Engineering" demonstration display cabinet is an electronic teaching equipment designed by introducing the most mainstream teaching philosophy of mechanical manufacturing engineering, combining the 12th and 13th Five Year Plan textbooks, and combining the mechanical teaching syllabus of universities, vocational schools, technical schools, and vocational schools. The demonstration is lifelike, reliable in operation, and the production process is beautiful. The use of this display cabinet can improve teaching effectiveness and save class hours. It is a modern mechanical course teaching application laboratory equipment.
2、 Technical specifications:
1. This display cabinet is composed of twenty individual display cabinets, with an external dimension of 1200 × five hundred and fifty × 1860mm (width × thick × High. Material: The cabinet is made of SPCC cold-rolled steel plate with a net thickness of 1.0mm or more, which is processed by bending, welding, phosphating, and spray painting (orange matte treatment), and is finely processed. The cabinet body has good steel properties, and the process is carefully designed to ensure that there are no scratches when the coin is scratched. The panel inside the cabinet is composed of laser printed text annotations and photographic charts, which are professionally coated and rolled without bubbles. The model material inside the cabinet is a combination of aluminum alloy, physical objects, partially transparent organic glass, and engineering plastics. Beautiful and elegant appearance, durable and long-lasting.
2. The model actions and explanations of the mechanism in the display cabinet are composed of a new second-generation multifunctional voice playback control system:
2.1. The system control has a password protection function, and students cannot start the touch screen without a password provided by the teacher. It has a strong guarantee function for controlling the entire product. The control program sequence is composed of touch screen buttons, microcontroller, relay, motor (and sound player), model, etc.
2.2. Touch screen (available from different brands with different specifications of 4.3 inches, 5 inches, and 7 inches), the touch screen program includes: welcome interface, password input interface, and control interface,
2.3. The key content includes: sound size control key, loop play key, stop key, and number key. The synchronization of model actions and voice explanations can be achieved through button operation.
3. The top of the display cabinet is equipped with lighting fluorescent lamps and control switches, and the back of the cabinet is equipped with opposite doors, which is beneficial for maintaining equipment and facilitating repairs. There is a cabinet box at the bottom of the cabinet, which facilitates the storage of individual models, experimental boxes, and related experimental documents.
