Automation Machine Equipment Shell has strict requirements for electromagnetic shielding, which are designed to protect the electronic components inside the equipment from external electromagnetic interference and prevent the electromagnetic radiation generated by the equipment itself from interfering with the outside world. The following is a detailed explanation of these requirements:
1. Necessity of electromagnetic shielding
With the rapid development of electronic technology, a large number of electronic components and circuits are integrated inside the automation machine equipment, which are extremely sensitive to the electromagnetic environment. External electromagnetic radiation, such as radar, radio waves, etc., may enter the interior through the gaps or holes in the equipment shell, interfering with the normal operation of the circuit, and even causing equipment failure. At the same time, the equipment itself may also generate electromagnetic radiation during operation, causing interference to other electronic equipment in the surrounding environment. Therefore, it is particularly important to electromagnetically shield the Automation Machine Equipment Shell.
2. Specific requirements
Material selection: The shell material must have good conductivity and electromagnetic shielding properties. Metal materials such as aluminum alloy and stainless steel are usually selected as shell materials. These materials can not only effectively block the entry of external electromagnetic radiation, but also limit the electromagnetic radiation generated inside the equipment to a certain range.
Structural design: The shell structure design needs to consider the needs of electromagnetic shielding. For example, continuous welding and overlapping are used to reduce the gaps at the joints to prevent electromagnetic waves from leaking through the gaps. At the same time, electromagnetic shielding materials or special treatments need to be installed at openings and holes to ensure that electromagnetic waves cannot enter or leave the equipment through these areas.
Grounding treatment: Good grounding is the key to electromagnetic shielding. The shell needs to be closely connected to the grounding system of the equipment to ensure that electromagnetic radiation can be quickly introduced into the earth through the grounding system, thereby reducing interference with the internal circuits of the equipment.
Electromagnetic compatibility test: During the design and manufacturing process, electromagnetic compatibility testing is required to verify whether the electromagnetic shielding performance of the shell meets the relevant standards and requirements. The test content includes but is not limited to radiation emission test, conducted emission test, radiation sensitivity test and conducted sensitivity test.
In summary, Automation Machine Equipment Shell needs to meet the requirements of material selection, structural design, grounding treatment and electromagnetic compatibility testing in terms of electromagnetic shielding. By taking these measures, the electronic components inside the equipment can be effectively protected from external electromagnetic interference, while preventing the electromagnetic radiation generated by the equipment itself from interfering with the outside world. This is of great significance to ensure the normal operation of automation machinery and equipment and improve the reliability and stability of the equipment.
