The X-axis mobile unit comprises an X-axis motor, an X-axis transmission shaft, a moving belt and an X-axis synchronous belt. The X-axis motor is arranged at one end of the support seat, the moving belt is arranged on the support seat and is located on the same side as the X-axis motor, the output shaft of the X-axis motor is connected to the moving belt in a transmission manner, and the X-axis synchronous belt is arranged at the other end of the support seat. The two ends of the X-axis transmission shaft are connected to the moving belt and the X-axis synchronous belt in a transmission manner respectively. The X-axis mobile unit drives the Y-axis mobile unit to move along the X-axis direction together, and the Y-axis mobile unit drives the antenna to move along the Y-axis direction for emitting electromagnetic waves. In the automatic test shielding box, the clamping device is used to place multiple products, the support seat is connected to the inner wall of the cavity of the chassis, and the antenna device is provided with multiple antennas to detect multiple products at the same time, which greatly improves the efficiency of the test and solves the problem of low test efficiency caused by one-to-one testing in the prior art.

[0051] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
