DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus for inspecting radio characteristics of an antenna for a mobile communication terminal according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an apparatus for inspecting radio characteristics of an antenna for a mobile communication terminal according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of an antenna mounting part 120 and an adsorption head 130 according to the present invention. The antenna to be inspected (RCA) described in this example is a conductor applied to the rear case of the mobile communication terminal.

1, an apparatus 100 for testing a radio communication characteristic of an antenna for a mobile communication terminal according to the present invention includes an inspection table 110, an antenna mounting unit 120, an adsorption head 130, a pneumatic unit 140, A conveyor 150, a defective product collecting unit 160, a transfer unit 170, a control unit 180, and a display 185. [ Hereinafter, the configuration of each element will be described.

The inspection table 110 is arranged spatially for inspection of an object RCA, and is a basic structure in which the detailed parts are installed, and is an inspection area to be handled by one operator. As will be described later, the inspection table 110 is disposed adjacent to a conveyor 150 for conveying good goods, and the good quality antennas RCA classified through one inspection table 110 are placed on the conveyor 150 And is collected at the final destination.

The antenna mounting portion 120 is a portion on which an antenna to be inspected of radio characteristics is placed on the inspection table 110. The plurality of antenna mounting portions 120 and the plurality of suction heads 130 may be provided so that the antennas RCA placed on the plurality of antenna mounting portions 120 are simultaneously attracted by the corresponding plurality of suction heads 130, And are classified according to whether they are good or defective.

The absorption head 130 is formed so as to elastically press or adsorb an inspection target antenna RCA placed on the antenna mounting portion 120. 2, the suction head 130 includes a cover plate 131 formed to cover the antenna mount 120, a suction unit 132 disposed at a plurality of locations of the cover plate 131, And a spring 133. As shown in Fig. The adsorption unit 132 is connected by a pneumatic line constituting a part of the pneumatic unit 140. The end of the adsorption unit 132 may be formed of a soft material so as to adsorb an inspection target antenna RCA on a smooth surface. The spring 133 provides an elastic force such that the suction portion 132 is elastically pressed against the antenna so that the antenna RCA and the antenna mounting portion 120 can be electrically connected to each other. Therefore, the suction head 130 is provided with an antenna RCA for transferring the tested antenna RCA while ensuring an electrical connection for the inspection target antenna RCA placed on the antenna mounting portion 120 by the operator It becomes a catching part.

The position of the adsorption unit 132 may vary depending on the size and shape of the object. In addition, it is also possible to provide a position changing hole 131a in one cover plate 131 so as to vary the position of the adsorption unit 132.

The antenna mount 120 and the adjacent antenna mount 120 may be spaced apart at a spatial distance to minimize interference between the antennas. Shielding films 135 and 121 for shielding the antenna to be inspected RCA may be included on the inner surface of the cover plate 131 or the inner surface of the antenna mount 120, respectively. Further, the edges of the antenna mount 120 and the cover plate 131 may include blocking walls 137 or additional elements such as gaskets to effectively block electromagnetic waves from adjacent antennas.

The human body detection sensor 123 and the switch unit 125 may be installed in front of the antenna mounting unit 120, respectively. The human body detecting sensor 123 is provided to detect whether a human body exists in the antenna mounting portion 120. The controller 180 controls the human body detecting sensor 123 to advance the examination in the absence of a human body . That is, if the operator does not remove the hand while the inspection target antenna (RCA) is placed on the antenna mounting portion 120, the influence of the radio characteristics due to the human body may be affected. Therefore, Respectively.

The switch unit 125 is installed to instruct the control unit 180 to start the inspection after the worker places the inspection object antenna RCA on the antenna mounting unit 120. [ As described above, the human body sensor 123 and the switch unit 125 are primary complementary elements for improving the accuracy and quality of the radio characteristic checking apparatus 100 of the antenna for a mobile communication terminal according to the present invention .

The pneumatic unit 140 may include a pneumatic pump, a pneumatic line, and a valve. By opening and closing the valve under the control of the controller 180, the adsorption head 130 adsorbs or drops the inspection target antenna RCA . The pneumatic unit 140 may include a terminal plate 141 for smooth port connection when the branching and inspection target antennas RCA are changed or replaced.

As described above, the conveyor 150 is configured such that good products out of the antennas to be inspected RCA can be transported. Specifically, the conveyor 150 may be formed in the form of a belt conveyor, and may have a width capable of accommodating the inspection target antennas RCA adsorbed by the plurality of antenna mounting portions 120 even if they fall down.

The defective product collecting unit 160 is a place where defective products are classified among the inspection target antennas RCA that have been inspected and adsorbed by the adsorption heads 130. The defective product collecting unit 160 can be a barrel or a box or a belt conveyor such as a conveyor 150 through which good goods are conveyed.

The defective article collection unit 160 may be located farther from the conveyor 150 or may be disposed between the antenna mounting unit 120 and the conveyor 150. [ Fig. 1 shows a case of a belt conveyor in the latter case.

The transfer unit 170 has a guide arm 171 and a transfer plate 172. The guide arm 171 is formed to be able to reciprocate the suction head 130 and is formed to extend to the positions of the conveyor 150 and the defective product collecting unit 160. The transfer plate 172 supports the suction head 130 and is formed to be slidable along the guide arm 171.

The controller 180 checks the radio characteristics of all the connected antennas RCA at once and checks all the antennas to be inspected RCA mounted on the antenna mounting part 120 to the suction head 130 And if there is a good product among the antennas to be inspected RCA, the suction head 130 is controlled to move the conveying unit 170 to a position where the conveyor 150 is located, The air is shut off and the good product is controlled to drop to the conveyor 150. If there is a defective product among the antennas to be inspected (RCA), the controller 180 controls the transport unit to move the adsorption head 130 to the location where the defective product collector 160 is located, and then moves the air of the pneumatic unit 140 So that the defective article is controlled to fall to the defective article collection unit 160. The control process of the controller 180 may be automatically performed after the operator puts the antenna to be tested RCA on the antenna mounting unit 120 and then turns on the switch unit 125. [ Therefore, since it is unnecessary for the operator to classify the good or defective product, a human error or a variation in the proficiency level is fundamentally prevented by the operator, and a plurality of RCAs to be inspected are simultaneously transferred (in one direction) Because it classifies good and defective products, the speed and ability of inspection are significantly improved.

3 is a conceptual diagram for explaining a multi-port connection concept for a plurality of inspection subject antennas RCA1 to RCAn in connection with the present invention. The control unit 180 may be connected to the multi-port switch 185 so that a plurality of antennas to be inspected (RCA) may be connected in connection with the present invention. The multiport switch 190 has a separate port 192 to be connected to a plurality of antennas to be inspected RCA1 to RCAn and the individual port 192 is connected to the port 180 of the controller 180 using the common port 191. [ (182). The standing wave ratio of each inspection target antenna RCA can be output to the monitor 181 in the control unit 180 through the channel change.

FIG. 4 is a diagram for explaining a range of radio characteristics of a good product through a voltage standing wave ratio (VSWR) of a reference antenna under the control of the control unit according to the present invention, and FIG. 5 is a diagram .

In this example, a high limit and a low limit, which are set for each band of the reference antenna, are generated from the voltage standing wave ratio (VSWR) of the reference antenna stored through the controller 180 It seems that the range of good products is decided. Specifically, when the reference antenna of the control unit 180 is mounted on the antenna mounting unit 120, the voltage standing wave ratio of the reference antenna is extracted and stored, and the upper limit LH of the low band (LB: Low Band) And controls to generate the upper limit HH and the lower limit HL of the lower limit LL and the higher band HB, respectively. The range setting process of the automated good product leads to a reduction in time, a prevention of error by the operator, and an improvement in deviation, compared with the passive inspection process by the existing operator.

When the reference antenna is mounted on the antenna mounting part 120, the controller 180 sets the reference value (first reference value) by detecting the antenna characteristic of the reference antenna. After the reference antenna is detached, , The limit characteristic (good range) can be automatically set by using the first reference value and the second reference value, by detecting the antenna characteristic of the limit antenna and setting the limit value (second reference value). Here, the reference antenna means an antenna having a precise reference characteristic, which is a previously manufactured antenna having an optimal quality. Further, when setting the first reference value of the reference antenna, the target value of the marker of the reference antenna can be set. The second reference value can be set based on the target value of the marker. The limit antenna is a prefabricated antenna having a minimum quality as a good product. The limit antenna includes an upper limit antenna and a lower limit antenna. In this case, the second reference value includes the upper limit reference value and the lower limit reference value.

Thus, when the first reference value and the second reference value are obtained, the limit range is automatically set by using these two values. More specifically, the first reference value and the second reference value are obtained by dividing into a low-band and a high-band, respectively, so that a high-limit range and a low-band limit range can be automatically set. That is, the range of the limit is not the range in the whole band but the range of the specific band is the limit range, and the target of the marker is used to set the specific band.

6 is a perspective view of an apparatus 200 for testing a radio characteristic of an antenna for a mobile communication terminal according to another example of the present invention. Here, as an antenna to be inspected shown in Fig. 1, an inspection apparatus for a single antenna (SA: Stand Alone) is shown instead of a rear case antenna. The inspection table 110, the conveyor 150, the defective product collecting unit 160, the control unit 180, and the like in FIG. 1 are not limited to the table 210, the conveyor 250, the defective product collecting unit 260, 280, but there is a difference in that a pair of transfer units 270A, 270B arranged parallel to each other are provided. That is, the antenna mounting portion 220A, the suction head 230A, the human body sensor 223A and the switch portion 225A, the display 285A, and the like are provided corresponding to the first transfer unit 270A, Similar elements are provided corresponding to the transfer unit 270B. By arranging the equipment having the two transfer units 270A and 270B, the space can be utilized more efficiently and the working speed and the inspection capacity can be increased. In addition, it is possible to obtain the maximum number of antennas and to secure the separation distance in order to minimize the mutual coupling between the worker's work space and the antenna through the facing arrangement. Each of the transfer units 270A and 270B can be configured to be capable of independent transfer.
