Description

Technical Field

[0001] This utility model belongs to the field of microwave anechoic chamber technology, and more specifically, it relates to a microwave anechoic chamber turntable microwave absorbing material combination handling device. Background Technology

[0002] Microwave anechoic chambers are widely used in aerospace, electronics, and communications fields. Inside the anechoic chamber is a test turntable on which the test object (DAPI) is fixedly placed. During testing, the DAPI rotates with the turntable. When the DAPI moves in or out of the turntable, the absorbing material on top of the turntable must be moved off the turntable surface. This involves a large moving area, is labor-intensive, and manual handling can easily damage the absorbing material, impairing its performance.

[0003] Because the turntable rotates continuously, the microwave absorbing material handling device above the turntable must not interfere with the turntable's continuous rotation, whether it is leaving the turntable or positioned above it. In existing technology, the microwave absorbing material is typically moved manually. This method is inefficient, labor-intensive, and can damage the material. Therefore, to improve the efficiency of moving microwave absorbing material above the turntable, a specialized device for moving microwave absorbing material above the turntable is urgently needed.

After reaching the position, the electromagnet 1.5.4 is de-energized, and the electromagnetic force disappears, realizing the reset of the wave-absorbing material. The driven vehicle 2 can rotate with the turntable. When the driven vehicle 2 leaves the turntable, the turntable can also rotate normally.
