Abstract

The invention discloses an electromagnetic wave absorbing material performance testing device. The device comprises a streamline frame; universal wheels are connected to the periphery of the bottom end of the streamline frame, and a product feeding box is fixedly connected to the upper part of one side of the streamline frame. The device has a direct effect that the performance of the wave absorbing material can be detected in real time, the quality of products is guaranteed, the risk of customer complaint is reduced, an impedance analysis meter test product is prevented from the loss of scrap, and the costs are saved; if only the inductance value is detected, a lower inductance value standard is set, the pass rate is high, but defective products with poor magnetic conductivity will be mixed with good products; a higher inductance value standard is set, although the magnetic conductivity can be ensured to be above the standard, a plurality of good products will be missed by mistake, soa third kind of determination type can be realized, that is, the inductance value only changes along with the magnetic conductivity such that an anticipated effect is achieved; and the mechanism thatthe design adopts is simple in structure and high-efficiency, and the practical efficiency of the current electromagnetic wave absorbing material performance testing device can be greatly improved.

Description

Technical field: [0001] The invention belongs to the field of testing equipment for electromagnetic wave absorbing materials, in particular to a performance testing device for electromagnetic wave absorbing materials. Background technique: [0002] Absorbing material is a commonly used magnetic material, which can be used for absorption, conduction and shielding of electromagnetic waves. It can play a very good role in solving electromagnetic wave EMI / ESD problems. It is an excellent material for electronic products to quickly achieve EMC electromagnetic compatibility. It can also be applied In wireless charging of consumer electronics products, NFC / RFID near field communication and other wireless fields. [0003] A functional product needs to be tested to accurately evaluate its performance. The same is true for electromagnetic wave absorbing materials. The current more accurate conventional solution is to prepare samples of the product and then use an impedance analyzer wi...
