BACKGROUND

1. Technical Field The present disclosure relates to testing devices, and, more particularly, to an automated antenna testing device applicable to a testing operation over the air.

2. Description of the Prior Art

Current communication transmission is in fourth generation (4G), and is under development toward fifth generation (5G), which provides greater wireless transmission bandwidth, from 28 GHz to 52.6 GHz (3gpp R15), even to as high as 73 GHz.

Compared to the current 4G antenna testing, which is conducted at a system end (such as mobile phones, tablet personal computers etc.), the 5G antenna testing has to be conducted at a packaging and testing end, since the mmWave band has been changed to Antenna in Package (AiP) packaging design.

Currently, the electric testing device used by a packaging and testing factory during a packaging and testing stage employs a metal compressing fixture to compress a chip-to-be-tested. However, the metal compressing fixture induces a metal shielding effect, which will interfere the antenna. Therefore, the antenna cannot be tested in an over the air (OTA) testing environment.

Therefore, how to design an automated antenna testing device that is applicable in an OTA testing environment, meets the antenna testing requirements, and is compatible with other processes is becoming an urgent issue in the art.

SUMMARY

In view of the drawbacks of the prior art, the present disclosure provides an automated antenna testing device, comprising: a machine part; a cavity part installed on the machine part and having a receiving space; a carrying stand installed in the receiving space, for objects-to-be-tested to be carried thereon; an antenna stand installed in the receiving space and corresponding to the carrying stand, for an antenna to be installed thereon that receives an signal from the objects-to-be-tested or transmits an signal to the objects-to-be-tested; and a conveyance device installed on the machine part and configured for moving the objects-to-be-tested to the carrying stand, wherein the conveyance device and the cavity part are installed independently.

FIGS. 1A to 1E are schematic diagrams of an automated antenna testing device 1 according to the present disclosure. The automated antenna testing device 1 comprises a machine part 1a, a cavity part 10, a cover 11, a carrying stand 12, an antenna stand 19, a conveyance device 13 and an actuation device 14 (detailed in FIGS. 3A and 3B).

In an embodiment, the automated antenna testing device 1 employs an over the air (OTA) testing environment.

The machine part 1a is a supporting structure of the automated antenna testing device 1, and can be designed to have interior and exterior appearances on demands, including shelfs, frames, stands or other suitable structures, to support the cavity part 10, the conveyance device 13 and the actuation device 14. The drawing shows a portion of the machine part 1.

In an embodiment, the machine part 1a is provided with a carrying plate 7, for a plurality of objects-to-be-tested 8 to be placed thereon, for facilitating the automation of production lines. In an embodiment, the objects-to-be-tested 8 are electronic components, such as an active element (e.g., a semiconductor chip), a passive element (e.g., a resistor, a capacitor and an inductor), a packaging component, or a combination thereof. In another embodiment, the packaging component comprises a substrate, a chip disposed on the substrate, and an encapsulation layer encapsulating the chip. In yet another embodiment, the objects-to-be-tested 8 are components having an antenna structure.

The cavity part 10 is disposed on the machine part 1a, and has a receiving space S and an opening 100 in communication with the receiving space S, as shown in FIG. 1C. The receiving space S is defined with an inactive region A adjacent to and corresponding to the opening 100 and an active region B adjacent to the inactive region A.

In an embodiment, the cavity part 10 is composed of six approximately rectangular boards 10a, 10b, 10c, 10d, 10e and 10f, and the receiving space S is formed among the boards 10a, 10b, 10c, 10d, 10e and 10f. In another embodiment, the opening 100 is formed on the lower board 10f (i.e., a bottom board). In yet another embodiment, the cavity part 10 and the receiving space S are in other forms.

The carrying stand 12 is disposed within the inactive region A of the cavity part 10 for carrying and locating the objects-to-be-tested 8 within the inactive region A. A top surface of the carrying stand 12 is used as a base surface L to define a space under the base surface L to be used as the inactive region A, and another space above the base surface L to be used as the active region B. In other words, the active region B is formed between the carrying stand 12 and the antenna stand 19.

In an embodiment, the carrying stand 12 is a testing stand having associated circuits arranged therein and electrically connected to the objects-to-be-tested 8.

The carrying stand 12 is disposed at the lower board 10f (i.e., the bottom board), and is exposed from a surface of the lower board 10f (i.e., the bottom board).

The opening 100 adjacent to an edge of the carrying stand 12, and has unparallel first and second channels 100a and 100b in communication with each other. In an embodiment, the opening 100 is L-shaped along the edge of the carrying stand 12 (as shown in FIG. 1D or 1E), or is in a shape of a hoof, an open ring etc.

The active region B is a seamless region without metal therein.

The antenna stand 19 corresponds to the carrying stand 12 and is disposed on a wall surface of the active region B of the cavity part 10, for receiving a signal from the objects-to-be-tested 8 or transmitting a signal to the antenna 9 of the objects-to-be-tested 8.

In an embodiment, the antenna stand 19 is disposed on the upper board 10a (i.e., a top board) and corresponds to the carrying stand 12. In another embodiment, the antenna stand 19 is disposed at a position of the cavity part 10 in any angle direction, depending on the specification of the antenna product.

The cover 11 (as shown in FIGS. 1D, 3A and 3B) covers the opening 100, and seals the receiving space S, which is thus closed.

The conveyance device 13 is disposed on the machine part 1a for moving the objects-to-be-tested 8 between the carrying stand 12 and the carrying plate 7 and placing the objects-to-be-tested 8 on the carrying stand 12 or on the carrying plate 7 on demands. The conveyance device 13 and the cavity part 10 are arranged independently.

In an embodiment, the conveyance device 13 comprises a track 13b disposed on the machine part 1a, and a robotic arm 13a configured for picking and placing the objects-to-be-tested 8 on the carrying stand 12. The robotic arm 13a absorbs and secures the objects-to-be-tested 8, and then moves the objects-to-be-tested 8. In an embodiment, the robotic arm 13a comprises a plurality of picking and placing parts 130 configured for absorbing and securing the objects-to-be-tested 8, and the track 13b is disposed between the opening 100 and the carrying plate 7, allowing the robotic arm 13a to move along a straight line between the opening 100 and the carrying plate 7 and access the cavity part 10 through the opening 100. In another embodiment, the conveyance device 13 absorbs and secures the objects-to-be-tested 8, and the picking and placing parts 130 are sucking discs or other suitable structures.

The first channel 100a is used for allowing the robotic arm 13a of the conveyance device 13 to access the cavity part 10 (e.g., upward and downward, as shown in FIGS. 1C and 1E), and the second channel 100b is used for allowing the conveyance device 13 to move in the cavity part 10 (e.g., horizontally, as shown in FIGS. 1D and 1E). In the automated antenna testing device 1, the active region B of the cavity part 10 and the conveyance device 13 are disposed separately, and the cavity part 10 is an independent mechanism. Therefore, no metal or other objects that will interfere the testing will be within the active region B during the testing operation.

The conveyance device 13 enters the cavity part 10 through the opening 100 (below) of the inactive region A, and the opening 100 of the cavity part 10 corresponding to the conveyance device 13 adjacent to the inactive region A, without being adjacent to the active region B. Therefore, the active region B, in which the testing is conducted, is a seamless space and signals will not be lost.

The conveyance device 13 accesses the opening 100 of the cavity part 10 at a position corresponding to where the carrying stand 12 is disposed. In an embodiment, any position corresponding to the base surface L and being away from the active region B will do, e.g., any position within the inactive region A. As shown in FIG. 4, since the inactive region A and the active region B are defined by the base surface L, the cavity part 10′ can be designed on demands, in which the opening 100 is formed at a position of the right-hand side board 10d corresponding to the inactive region A, and the carrying stand 12 is disposed on the lower board 10f. In another embodiment, the inactive region A or the opening 100 can be disposed at either side of the cavity part.

The actuation device 14 (as shown in FIGS. 3A and 3B) is disposed outside of the cavity part 10, e.g., on the machine part, to move the cover 11, allowing the cover 11 to be engaged with or separated from the opening 100.

In an embodiment, the actuation device 14 comprises at least one pneumatic component 140, such as an air cylinder, to move the cover 11 to be close to or away from the opening 100. In an embodiment, the pneumatic component 140 provides a first force (in a first direction Y1 shown in FIG. 3A) to raise the cover 11 with respect to the bottom board 10f and separate the cover 11 from the opening 100, and, through a recovery mechanism of the air cylinder, lowers the cover 11 slowly to allow the cover 11 to be engaged with the opening 100 (as shown in FIG. 3B). In another embodiment, in consideration of scheduling of the automatic production lines, the pneumatic component 140 is a two-way air cylinder, which can provide a second force (in a second direction Y2 shown in FIG. 3B), to speed up downward speed of the cover 11. Therefore, the time for the testing operation is reduced significantly.

The pneumatic component 140 is disposed corresponding in position to the opening 100. In an embodiment, the pneumatic component 140 is disposed at two opposite ends of the opening 100, as shown in FIG. 1D. In an embodiment, the L-shaped opening 100 has a straight line segment, through which the robotic arm 13a ascends and enters the receiving space S of the cavity part 10, and a transverse segment, in which a moving space provides the robotic arm 13a to pick and place the objects-to-be-tested 8 in the cavity part 10. Refer to FIGS. 2A to 2D. During operation of the automated antenna testing device 1, the robotic arm 13a moves along the track 13b to the carrying plate 7, one of the picking and placing parts 130 absorbs one of the objects-to-be-tested 8′, and then the robotic arm 13a moves along the track 13b to a region under the opening 100 (in a moving direction X1 shown in FIG. 2A). Then, the actuation device 14 moves the cover 11 upward, allowing the cover 11 to be separated from the opening 100, while the picking and placing parts 130, through the robotic arm 13a, move upward (in a moving direction Z1 shown in FIG. 2A) to the receiving space S, and stretch horizontally with respect to the bottom board 10f (or rotate horizontally with respect to the surface of the bottom board 10f), to place the objects-to-be-tested 8′ on the carrying stand 12 (as shown in FIG. 2B). Then, the picking and placing parts 130 move along the track 13b to the opening 100 (in a moving direction X2 shown in FIG. 2B) and move downward and outside of the receiving space S (in a moving direction Z2 shown in FIG. 2C), while the actuation device 14 moves the cover 11 to move downward and be engaged with the opening 100, and the pneumatic component 140 moves out of the receiving space S to conduct a testing operation, such as sensing the antenna signals f1 and f2 between the antenna 9 on the antenna stand 19 and the objects-to-be-tested 8′ on the carrying stand 12 shown in FIG. 2C.

The conveyance device 13 and the actuation device 14 actuate synchronously. Therefore, the working time is reduced, the operation efficiency of the testing process is increased, and the overall time spent in the packaging and testing process is reduced significantly.

In an embodiment, if an object-to-be-tested 8 that is tested completely is placed on the carrying stand 12, as shown in FIG. 2A, another of the picking and placing parts 130 of the robotic arm 13a can absorb and move the object-to-be-tested 8 that is tested completely onto the carrying plate 7, as shown in FIG. 2D, and absorb another object-to-be-tested 8″.

After the robotic arm 13a enters the cavity part 10, the placement of the objects-to-be-tested 8′, 8″, which are not tested yet, and the picking of the objects-to-be-tested 8, which are tested completely, can be conducted subsequently, as shown in FIGS. 2A to 2D. Therefore, the working time is reduced, the operation efficiency of the testing process is increased, and the overall time spent in the packaging and testing process is reduced significantly.

After the OTA testing operation of the objects-to-be-tested 8′ is complete, the conveyance device 13 picks and places the objects-to-be-tested 8′ on the carrying plate 7, and places another objects-to-be-tested 8″ on the carrying stand 12.

In the automated antenna testing device 1 according to the present disclosure, the cavity part 10, 10′ and the conveyance device 13 are disposed independently. Therefore, other components associated with automatic design (not shown) in the automated antenna testing device 1 will not interfere the OTA testing environment, the automatic OTA testing is achieved, and the yield is increased. The conveyance device 13 or the cavity part 10, when malfunctioned, can be detached individually, to facilitate the replacement operation. In the automated antenna testing device 1 according to the present disclosure, both the conveyance device 13 and the actuation device 14 access the cavity part 10 through the opening 100 of the inactive region A, and the conveyance device 13 and the actuation device 14 are outside the cavity part 10 when the antenna is tested, no metal or other objects that will interfere the testing of the antenna will exist when the antenna is tested within the active region B, which is a seamless space. Therefore, the testing of the antenna will not be interfered.

In an embodiment, any type of antenna devices disposed on the antenna stand 19 and objects-to-be-tested 8 corresponding thereto can be arranged on demands, and a desired testing can be conducted, in addition to the previously mentioned OTA testing operation.

The foregoing descriptions of the detailed embodiments are only illustrated to disclose the features and functions of the present disclosure and not restrictive of the scope of the present disclosure.
