Here are some methods to increase the adsorption force of magnetic component trays:

1、 Starting from the magnetic material itself

Select high magnetic materials

Use permanent magnet materials with stronger magnetism to make the tray. For example, neodymium iron boron (Nd-Fe-B) is currently one of the strongest magnetic permanent magnet materials. If ordinary ferrite magnetic materials are replaced with neodymium iron boron materials to make the magnetic part of the tray, its adsorption force will be significantly enhanced.

For some industrial scenarios with special requirements, samarium cobalt (Sm Co) magnetic materials can also be considered. Samarium cobalt permanent magnet materials also have strong magnetic properties and good high-temperature resistance, making them suitable for magnetic component trays working in high-temperature environments.

Increase the thickness or volume of magnetic materials

For the magnetic layer at the bottom or side of the tray, increase its thickness within the allowable design range. According to the relationship between magnetic field strength and magnetic material volume, appropriately thickening the magnetic material layer can enhance the magnetic field strength, thereby improving the adsorption force.

For example, if it is a rectangular magnetic component tray, increasing the laying area or height of magnetic materials at the bottom of the tray without changing the overall size of the tray can effectively enhance the adsorption force.

Optimize the arrangement of magnetic materials

Adopt a reasonable layout of magnetic material arrays. For example, arranging multiple small magnetic units in a certain pattern, such as honeycomb or circular arrangement, can make the magnetic field distribution more uniform and concentrated on the surface of the tray, thereby improving the adsorption force.

The optimal arrangement of magnetic materials can be designed by simulating magnetic field distribution software to enhance the adsorption force.

2、 Improve the structural design of the tray

Reduce the distance between the tray and the parts

Try to minimize the distance between magnetic components and magnetic sources during design. For example, embedding magnetic materials on the surface of the tray instead of placing them deeper at the bottom of the tray can reduce the attenuation of the magnetic field, allowing the parts to be closer to the magnetic field source and enhancing the adsorption effect.

For multi-layer trays, the magnetic layer can be placed on the top layer and a thin and flat isolation layer can be used to reduce the distance between the parts and the magnetic layer.

Increase the number of magnetic sources

Reasonably add magnetic sources at different positions on the tray. For example, in addition to placing magnetic materials at the bottom of the tray, small magnetic strips or blocks can also be added to the sides of the tray.

For large magnetic component trays, a partition design can be adopted, with each partition having an independent magnetic source. Through reasonable circuit control, these magnetic sources can work together to enhance the overall adsorption force.

3、 External auxiliary means

Use magnetic enhancers (in some cases)

In some special application scenarios, such as storing precision instrument parts with extremely high adsorption requirements, magnetic enhancers can be considered. This enhancer is usually a liquid or paste, and its main component is magnetic particles that can enhance the magnetic field.

Applying magnetic enhancer to the magnetic surface of the tray can enhance the magnetic field strength to a certain extent, thereby improving the adsorption force. However, it should be noted that this method may be affected by environmental factors such as temperature and humidity, and requires regular maintenance and reapplication.

Combining other adsorption methods

Combining electrostatic adsorption and magnetic adsorption. For example, setting up an electrostatic adsorption film on the surface of the tray can assist in fixing the parts when the magnetic adsorption force is insufficient.

This combined adsorption method can be applied in some scenarios that require very strict fixation of parts, such as the storage and transportation of aerospace parts.
