The present disclosure relates to a testing device; in particular, to a radiofrequency (RF) testing apparatus and a movable testing device.
An object (e.g., an RF chip) needs to be moved into the conventional RF testing apparatus by manpower before the RF testing process is implemented, so that the testing efficiency of the conventional RF testing apparatus needs to be increased. Moreover, in order to get an accurate testing result for the object, the electromagnetic shielding effect of the conventional RF testing apparatus needs to be improved for preventing any external signal from entering into the conventional RF testing apparatus.
The present disclosure provides an RF testing apparatus and a movable testing device to effectively improve the drawbacks associated with conventional RF testing apparatuses.
The present disclosure discloses a radiofrequency (RF) testing apparatus, which includes an automatically testing platform and a movable testing device. The automatically testing platform has a testing space and an inserting hole in air-communication with the testing space. The movable testing device includes a case module, an aligning box, a lift mechanism, and an electromagnetic shielding cloth. The case module has a first accommodating space in an interior thereof. A top portion of the case module has a first opening in air-communication with the first accommodating space. The aligning box has a second accommodating space in an interior thereof. A bottom portion of the case module has a second opening in air-communication with the second accommodating space. The lift mechanism connects the case module and the aligning box. The lift mechanism is configured to rise or fall the aligning box with respect to the case module. The electromagnetic shielding cloth is formed as a tubular structure having a first end portion and an opposite second end portion. The first end portion of the electromagnetic shielding cloth is seamlessly fastened to the case module and is arranged around the first opening. The second end portion of the electromagnetic shielding cloth is seamlessly fastened to the aligning box and is arranged around the second opening. An inner space of the electromagnetic shielding cloth is defined as an adjustable channel in air-communication with the first accommodating space and the second accommodating space. The cooperation between the electromagnetic shielding cloth and the case module and the cooperation between the electromagnetic shielding cloth and the aligning box are configured to block an external electromagnetic signal to enter into the first accommodating space and the second accommodating space through the first opening and the second opening. When the movable testing device is moved toward the automatically testing platform to arrange the aligning box under the inserting hole, the lift mechanism is configured to move the aligning box to enter into the testing space through the inserting hole.
The present disclosure also discloses a movable testing device, which includes a case module, an aligning box, a lift mechanism, and a flexible shielding member. The case module has a first accommodating space in an interior thereof. A top portion of the case module has a first opening in air-communication with the first accommodating space. The aligning box has a second accommodating space in an interior thereof. A bottom portion of the case module has a second opening in air-communication with the second accommodating space. The lift mechanism connects the case module and the aligning box. The lift mechanism is configured to rise or fall the aligning box with respect to the case module. The flexible shielding member is formed as a tubular structure having a first end portion and an opposite second end portion. The first end portion of the flexible shielding member is seamlessly fastened to the case module and is arranged around the first opening. The second end portion of the flexible shielding member is seamlessly fastened to the aligning box and is arranged around the second opening. An inner space of the electromagnetic shielding cloth is defined as an adjustable channel in air-communication with the first accommodating space and the second accommodating space.
In summary, the movable testing device of the present disclosure can be moved toward the automatically testing platform to arrange the aligning box under the inserting hole, and the lift mechanism can be operated to move the aligning box to accurately enter into the testing space through the inserting hole, thereby effectively increasing the testing efficiency of the RF testing apparatus.
Moreover, the RF testing apparatus (or the movable testing device) can be used to block an external electromagnetic signal to enter into the first accommodating space and the second accommodating space through the first opening and the second opening by using the cooperation between the electromagnetic shielding cloth and the case module and the cooperation between the electromagnetic shielding cloth and the aligning box.

Specifically, the first end portion 71 of the electromagnetic shielding cloth 7 is seamlessly fastened to the case module 1 and is arranged around the first opening 113, the second end portion 72 of the electromagnetic shielding cloth 7 is seamlessly fastened to the aligning box 2 and is arranged around the second opening 22, and an inner space of the electromagnetic shielding cloth 7 is defined as an adjustable channel 74 in air-communication with the first accommodating space 111 and the second accommodating space 21. Thus, the cooperation between the electromagnetic shielding cloth 7 and the case module 1 and the cooperation between the electromagnetic shielding cloth 7 and the aligning box 2 are configured to block an external electromagnetic signal to enter into the first accommodating space 111 and the second accommodating space 21 through the first opening 113 and the second opening 22.
It should be noted that the electromagnetic shielding cloth 7 in the present embodiment has a specific stiffness and is not a soft structure. In order to have a better shielding effect on the cooperation between the electromagnetic shielding cloth 7 and the case module 1, the electromagnetic shielding cloth 7 and the case 11 of the case module 1 are preferably provided with a soft conductive material arranged there-between for achieving a seamless connection between the electromagnetic shielding cloth 7 and the case 11.
Specifically, the first end portion 71 of the electromagnetic shielding cloth 7 and the first conductive foam 13 are sandwiched between the first holder 14 and the first ridge 114 so as to substantially establish a seamless connection between the first end portion 71 of the electromagnetic shielding cloth 7 and the first conductive foam 13. The second end portion 72 of the electromagnetic shielding cloth 7 and the second conductive foam 24 are sandwiched between the second holder 25 and the second ridge 23 so as to substantially establish a seamless connection between the second end portion 72 of the electromagnetic shielding cloth 7 and the second conductive foam 24.
In the present embodiment, the first conductive foam 13 is sandwiched between the first end portion 71 and the first ridge 114, and the second conductive foam 24 is sandwiched between the second end portion 72 and the second ridge 23, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure, the first conductive foam 13 can be sandwiched between the first end portion 71 and the first holder 14, and the second conductive foam 24 is sandwiched between the second end portion 72 and the second holder 25.
