Description

RF ID based reel receiver

The present invention relates to a radio frequency identification (RFID) technology, and more particularly, to a technology for recognizing information of a reel using an RFID ID.

RF ID (RFID) system is a non-contact recognition system that attaches RFID tags to various items and transmits and processes information and surrounding environment information on a radio frequency. The RFID ID system, which consists of a reader with a reading function, an RFID ID tag with unique information, operating software and a network, reads the information by identifying the RFID tag attached to the article. RF ID system's radio frequency identification technology does not require direct contact or scanning in the visible band like a barcode. Because of these advantages, it is evaluated as a technology to replace the bar code, and its use range is very wide. However, according to the structure of the antenna for reading the RFID tag, an area in which the RFID tag cannot be read may occur, which degrades the accuracy of article information recognition.

Meanwhile, an electronic component may be stored in a device called a reel. For example, the electronic component may be stored in the reel in a form in which a tape on which the electronic component is loaded is wound on a reel. The reel may be attached with an RFID tag that can know information about the stored electronic components. And, a reel receiver may be used to store and manage the reels. However, when many reels are stored in the reel storage device, the user has to lift the reels one by one in order to find a reel loaded with electronic components, which is a waste of time and money.

According to an embodiment of the present disclosure, an RFID ID based reel storage device capable of accurately recognizing information of a reel using an RFID ID is proposed.

According to an embodiment of the present invention, an RFID ID-based reel storage device has an open part and is accommodated so as to cover a plurality of reels equipped with an RFID tag, and a three-dimensional closed loop is formed on the storage part. A first loop antenna for reading the RFID tag of the reel, and a three-dimensional closed loop is formed on the housing, and a part of the transmission / reception area overlaps with the first loop antenna to read the RFID tag of the reel stored at the corresponding position. And a control unit for recognizing the reel information by identifying the two loop antenna and the read RFID tag.

The accommodating part according to an exemplary embodiment has a shape surrounding each reel to accommodate at least a center position of each reel.

Each loop antenna according to an embodiment forms a closed loop along the shape of the housing.

Each loop antenna according to an exemplary embodiment has an RF transceiver and a ground unit for transmitting an RF signal for reading an RFID tag, for receiving an RF tag signal in response to the transmitted RF signal, and inputting the RF tag signal to the controller.

The reel receiver may further include a switching unit for sequentially activating the RF transceiver of each loop antenna in a state in which the ground unit of each loop antenna is activated. At this time, a portion of the first loop antenna and the second loop antenna may be adjacent to each other, but may be separated by an inactivated loop antenna so as not to affect the RFID tag recognition of the activated loop antenna.

The reel receiver may further include a switching unit that sequentially activates the RF transceiver and the ground unit of each loop antenna.

The reel receiving device may further include a display unit displaying reel information identified by the control unit. In this case, when the user wants to find a reel in which a predetermined electronic component is loaded, the controller finds an accommodating position of the reel in which the corresponding electronic component is loaded using the pre-stored RFID tag information, and determines the storing position of the reel through the display unit. I can tell you.

The reel receiving apparatus may further include a sensor for detecting whether the reel is accommodated, and the controller may read the RFID tag of the reel through each loop antenna only when detecting the reel receiving through the sensor.

According to an embodiment of the present disclosure, as long as the reel is stored in the reel storage device, the RFID tag recognition rate may be increased by recognizing all the RFID tags of the plurality of reels. In particular, through the structure in which a part of the transmit / receive region overlaps between loop antennas for reading the RFID tag, the RFID tag of the reel can be recognized even in a blank area in which the RFID tag cannot be read. In addition, as a part of each loop antenna is adjacent to an inactive loop antenna and has a structure that is spaced apart in a range that does not affect the RFID tag recognition of the activated loop antenna, even in an area where the RFID tag cannot be read. You can recognize RF tags. In addition, when the RFID tag is recognized, the user may easily check whether the RFID tag is recognized.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention; In the following description of the present invention, if it is determined that detailed descriptions of related well-known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intention or custom of a user or an operator. Therefore, the definition should be made based on the contents throughout the specification.

1 is an external view of an RFID ID based reel storage device 1 according to an embodiment of the present invention.

Referring to FIG. 1, the reel receiving device 1 includes a loop antenna array 12 including an accommodating part 10, a first loop antenna 12-1, and a second loop antenna 12-2. .

The storage unit 10 has a space for accommodating the reels 20-1, 20-2-2, and the received reels 20-1, 20-2 span the storage unit 10 and are aligned in a line. Support as much as possible. In this case, the storage unit 10 serves as a shelf for storing and managing the reels 20-1 and 20-2. Although only two reels are shown in FIG. 1, the number of reels is not limited thereto. In addition, the reels accommodated may have the same size or may have different sizes. For example, the outer diameters may be different from each other, and the inner diameters may be different from each other.

The accommodating part 10 is partially opened for accommodating so that a user can easily store or take out the reels 20-1 and 20-2. The accommodating part 10 according to an exemplary embodiment has a shape surrounding the reels 20-1 and 20-2 by a predetermined portion or more so as to accommodate the center position or more of the reels 20-1 and 20-2. For example, as shown in FIG. 1, it is slightly higher than the half cylinder to accommodate more than the middle of the reels. In this case, the reels 20-1 and 20-2 can be stably supported, and the recognition rate of the RFID tag attached to each reel can also be increased. The housing 11 may be positioned outside the housing 10 to protect and support the housing 10.

The reels 20-1 and 20-2 accommodated in the accommodating part 10 may wind and store a strip in which electronic components are loaded, respectively. The electronic component may be a semiconductor chip, for example. RF tags are attached to the outer peripheries of the reels 20-1 and 20-2. The RFID tag may record identification information and manufacturing history data of the parts housed in the reel. The identification information is related to the parts stored in the reel, and may include a part code, a manufacturer name, a manufacturing year and a manufacturing lot number. The manufacturing history data represents the history of parts mounted on the reel and used for manufacturing, i.e., the date of use and the specification of the mounting work line / device mounted. In addition, the remaining amount information of the parts accommodated in the reel may be recorded in the RFID tag. The parts remaining information shows the number of remaining parts of the tape wound on the reel.

When a lot of reels are stored in the reel storage device 1, the user has to lift the reels one by one in order to find a reel loaded with electronic components, which is a waste of time and money. The present invention is a technology for automatically recognizing and managing the storage position of each reel accommodated in the reel storage device (1) so that the user can easily find the desired electronic components, in particular, the area that cannot recognize the RFID tag mounted on the reel In accordance with the antenna structure that can recognize the reel is a technology to accurately recognize the storage position of the reel.

Each loop antenna 12-1, 12-2 of the loop antenna array 12 reads an RFID tag mounted on the reel to identify each reel. To this end, each loop antenna 12-1, 12-2 transmits an RF signal and receives an RF tag signal in response to the transmitted RF signal. Each loop antenna 12-1, 12-2 forms a three-dimensional closed loop. For example, as shown in FIG. 1, each of the loop antennas 12-1 and 12-2 may have a hollow rectangular loop toward the accommodating part 10. Each of the loop antennas 12-1 and 12-2 may form a closed loop according to the shape of the accommodating part 10. For example, as shown in FIG. 1, each of the loop antennas 12-1 and 12-2 may be shaped like a semi-circle along the semi-cylindrical shape of the accommodating part 10. However, this is only an embodiment, and the shape of each loop antenna 12-1 and 12-2 may be modified into various geometric shapes, and may be located outside of the housing 10. Meanwhile, in FIG. 1, only two of the first loop antenna 12-1 and the second loop antenna 12-2 are illustrated, but the number of loop antennas is not limited thereto. Do not.

Each of the loop antennas 12-1 and 12-2 overlaps a part of the transmission / reception possible region. The transmit / receive area means a coverage that can transmit an RF signal and receive an RFID tag signal in response to the transmitted RF signal, and the range may vary depending on the performance of the antenna. A part of the second loop antenna 12-2 is positioned between the first loop antenna 12-1 and the second loop antenna 12 to overlap the transmit / receive areas of the loop antennas 12-1 and 12-2. A part of the first loop antenna 12-1 may be positioned between −2). The reason why a portion of the transmit / receive area of each loop antenna 12-1 and 12-2 overlaps will be described later with reference to FIGS. 2 and 3.

2 and 3 are reference diagrams for explaining a principle of eliminating a blank area by overlapping a part of a transmit / receive area of an adjacent loop antenna according to an embodiment of the present invention. 12-1) and a top view of the second loop antenna 12-2 from above. In detail, FIG. 2 is a reference diagram for explaining a blank area occurring in one closed loop antenna, and FIG. 3 is a reference view for explaining a closed loop antenna structure for blocking generation of a blank area.

Referring to FIG. 2, the current loop is formed in the direction of the arrow in the first loop antenna 12-1. At this time, the blank area 100 is generated as the magnetic fields due to the current flowing in one direction and the magnetic fields due to the current flowing in the opposite direction cancel each other. In the blank area 100, it is difficult for the first loop antenna 12-1 to recognize the RFID tag of the reel. This is coupled with degraded antenna performance and reduced accuracy of reel tag recognition rate.

Referring to FIG. 3, when the first loop antenna 12-1 alone exists, a blank area 100 in which magnetic fields cancel each other by currents flowing in opposite directions occurs, but the second loop antenna according to the present invention ( 12-2, the first loop antenna 12-1 and a part of the transmit / receive area overlap. In this case, the blank area 100 disappears due to the magnetic field due to the current flowing in the second loop antenna 12-2. Therefore, the RFID tag can be recognized even in the blank area 100, thereby improving the recognition rate. As shown in FIG. 3, a part of the first loop antenna 12-1 is blank of the second loop antenna 12-2 to overlap the transmit / receive area of each loop antenna 12-1 and 12-2. Located in the area, a portion of the second loop antenna 12-2 may be located in the blank area of the first loop antenna 12-1.

4 is a configuration diagram of the reel storage device 1 according to an embodiment of the present invention.

Referring to FIG. 4, the reel receiver 1 includes a loop antenna array 12, a controller 13, a switching unit 14, a display unit 15, and a memory 16.

The reel receiving device 1 is accommodated so that a part is opened and the reel 20 to which the RFID tag is mounted is spread. The reel 20 may wind and store a strip on which electronic components are loaded.

Each loop antenna 12-1, 12-2,..., 12-n constituting the loop antenna array 12 forms a three-dimensional closed loop, and reads the RFID tag of the reel 20 stored at the corresponding position. Each of the loop antennas 12-1, 12-2, ..., 12-n overlaps a part of the transmit / receive area with each other and reads the RFID tag. Each loop antenna 12-1, 12-2,..., 12-n may form a closed loop along the shape of the reel receiver 1.

The switching unit 14 sequentially activates each of the antennas 12-1, 12-2, ..., 12-n constituting the loop antenna array 12. The time to be activated may be periodic, which may be preset. For example, it may be activated in 0.5 seconds, but is not limited thereto. The switching unit 14 may select one of the antennas by switching the antennas 12-1, 12-2,..., 12-n. For example, the switching unit 14 may sequentially switch the antennas 12-1, 12-2, ..., 12-n, and the antennas 12-1, 12-2, ..., 12- n) one antenna may be selected. As another example, the switching unit 14 may activate another adjacent loop antenna to recognize the RFID tag only when one loop antenna does not recognize the RFID tag for a predetermined time. Meanwhile, as shown in FIG. 4, the loop antenna array 12 and the switching unit 14 may be formed as separate components, but each antenna and the switching unit 14 of the loop antenna array 12 may be integrated. It may be.

The control unit 13 identifies the RFID tag read through the RF signal transmission and reception from the antenna selected through the switching unit 14, and reads the storing position of the reel to which the identified RFID tag is attached. The read result can be output to the outside via the display unit 15. For example, when a user wants to find a reel in which an electronic component having predetermined information necessary for a process is loaded, the controller 13 automatically loads the electronic component using the RFID tag information stored in the memory 16. The storage position of the reel can be found and informed through the display unit 15. Accordingly, the user can save time and money because the user does not have to touch the reels one by one in order to find the desired reels.

The controller 13 may read tag information stored in the RFID tag of the reel 20, for example, identification information and manufacturing history data. For this purpose, the control unit 13 may be in the form of an RF reader. The controller 13 may read tag information from the RFID tag and output the read result to the outside through the display unit 15.

The control unit 13 controls the switching unit 14 to sequentially select one of the antennas. In addition, the controller 13 may obtain the reel position information from the RFID tag information of the reel obtained through the loop antenna array 12 and store it in the memory 16.

Hereinafter, the process by which the control part 13 recognizes the storing position of the reel 20 is mentioned later. The controller 13 controls the switching unit 14 to sequentially select predetermined antennas from the antennas of the loop antenna array 12. The controller 13 controls the selected antenna to output an RF signal to read the RFID tag of the reel 20, and receives the RFID tag signal read from the RFID tag of the reel 20 from the corresponding antenna. When the RF tag signal is received, the control unit 13 confirms that the reel 20 is stored around the antenna, reads the RFID tag information using the RF tag signal, and uses the read reel ( 20) It is determined whether or not the user wants the reel. In addition, the controller 13 may output the determination result to the outside through the display unit 14. For example, the controller 13 may emit light of the storage position of the reel 20 using light emission.

The memory 16 stores a program for the control unit 13 to execute various processing tasks. The location information of the reel 20 obtained from the RF tag information obtained through the control unit 13 may be stored. The memory 16 may be included in the reel storage device 1 or may be included in a separate server and connected to the reel storage device 1 through a network.

The memory 16 may store the total number of antennas constituting the loop antenna array 12 and the order for each antenna, and store RFID tag information of a reel identified through the currently selected antenna. For example, when the currently selected antenna of the total 16 antennas corresponds to the seventh, the RFID tag information identified through the seventh antenna may be temporarily stored in the memory 16. In addition, the memory 16 stores various data such as software for controlling the control unit 13 to sequentially select the antennas through the switching unit 14, antenna selection period information, antenna arrangement position information, and the like, and sequentially stores all the RF information. Can be recognized.

The display unit 15 displays an input command for operation and an operation screen at the time of input. And each storing position of the reel identified by the control part 13 is displayed. The display unit 15 may include light emitting means. The light emitting means may emit light through a light emitting diode (LED) to display storage position information identified by the controller 13.

The RF transmitting / receiving unit 70 transmits an RF signal for reading the RFID tag, and receives an RF tag signal in response to the transmitted RF signal. In this case, the first loop antenna 12-1 transmits the RF signal for reading the RFID tag, and the antenna pattern is configured to receive the RF tag signal again at the transmitted point. The RF transceiver 70 and the ground unit 72 may be formed on one side of the first loop antenna 12-1 as shown in FIG. 5A. The ground unit 72 may be used separately for each loop antenna, and may be used as a common ground of a plurality of loop antennas.

Referring to FIG. 5B, the switching unit 14 according to an exemplary embodiment sequentially activates the RF transceiver unit and the ground unit of each loop antenna. To this end, as illustrated in FIG. 5B, in the first loop antenna 12-1, the RF transceiver is connected to the first terminal 711 through the first line 701, and the ground part is connected to the second line ( 702 is connected to the first terminal 711. In the second loop antenna 12-2, the RF transceiver is connected to the second terminal 712 through the third line 703, and the ground part is connected to the second terminal 712 through the fourth line 704.

The switching unit 14 according to another embodiment sequentially activates the RF transceiver of each loop antenna while the ground unit of each loop antenna is activated. To this end, the ground portion of each loop antenna may be used as a common ground connected in common. In this case, each of the loop antennas may be spaced apart in a range that does not affect the RFID tag recognition of the activated loop antenna because some of the loop antennas are adjacent to the inactive loop antenna. Detailed description thereof will be described later with reference to FIGS. 6A to 6D.

The first loop antenna 12-1 generates a blank area A 810 that does not recognize the RFID tag. The blank area A 810 is activated due to activation of the second loop antenna 12-2 due to signal induced. The occurrence is eliminated.

In contrast, referring to FIG. 6B, when deactivating the first loop antenna 12-1 and activating the second loop antenna 12-2 adjacent to the first loop antenna 12-1, the second loop antenna When 12-2 is activated, current may be induced to the first loop antenna 12-1 which is not activated, and thus the first loop antenna 12-1 may be activated. The second loop antenna 12-2 generates a blank area B 820 that does not recognize the RFID tag, and due to activation of the first loop antenna 12-1 due to signal induction, The occurrence is eliminated.

Meanwhile, referring to FIG. 6C, when activating the first loop antenna 12-1 or the adjacent second loop antenna 12-2, the first loop antenna 12-1 or the adjacent agent is caused due to signal induction. A blank area C 830 may be generated between the two loop antennas 12-2 that do not recognize the RF tag.

Referring to FIG. 6D, in order to eliminate the occurrence of the blank area C 830, the first loop antenna 12-1 and the second loop antenna 12-2 are spaced apart by a predetermined distance 840. The separation distance is a distance within a range that is induced in an inactive loop antenna and does not affect RFID tag recognition of the activated loop antenna. The separation distance may vary depending on the transmission power of the RF signal. According to one embodiment, the separation distance may be set so that the degree of abandonment of the RF signal is 10%, but this is merely an embodiment for helping the understanding of the present invention, but is not limited thereto.
