Since the RFID tag can record a large amount of data, and the data in the RFID tag can be quickly read. Therefore, the use of RFID tags can keep track of the movements and current conditions of each object. For logistics management, the read rate of RFID tags is the most important • key. The RFID tag on the object should be read correctly to ensure that the data of the object can be read correctly during the shipment and purchase, avoiding the error or failure of reading the object data. Lu affects the logistics management of objects. To this end, a radio frequency identification tag detection platform is required to detect the read rate of the radio frequency identification tag. 1 is a conventional delivery device that can read a radio frequency identification tag.

The read gate 120 spans the transport device 11'' and the plurality of antennas 13'' are disposed on the read gate 120. When the objects on the transport device 11 pass through the read gate 120, the radio frequency signals emitted by the antennas 130 will read the radio frequency identification tag on the object to grasp the movement and current state of the object. Since the metal interferes with the RF signal emitted by the antenna 130, the roller 112b is made of a non-metallic material to prevent the roller U2b from interfering with the RFID tag of the antenna 130. However, such a conveying apparatus 110 having rollers 123a, 112b of two different materials has a complicated assembly time and assembly time, so that the assembly conveying apparatus 1 has a high assembly time cost.

Transport. Although there are two rollers 32 shown in Fig. 2, in the present embodiment, more than two rollers 320 can also drive the conveyor belt 330 without affecting the overall function of the first conveyor apparatus 300. Therefore, the number of rollers 32A of Figure 2 is merely illustrative and not limiting. The detection gate 210 spans the first conveyor 3〇〇 and is located above the RF signal transmission zone 312. The plurality of antennas 220 are configured for detection.

The read window adjusting member 350 is made of a material that can reflect the RF signal, such as a metal. In this embodiment, the read window adjusting member can be a reflective cover having a parabolic reflecting smface and the antenna 220 is disposed on the antenna. The focus of the parabolic reflecting surface of the window adjusting member 35〇 is to concentrate the RF signal emitted by the antenna 220, and the antenna 22 is easily detected by the antenna 22 to detect the RFID tag on the object. Theoretically, the antenna 22 is disposed at the focal position of the parabolic reflecting surface, but in practice, if the position of the antenna 22 is slightly offset, it should still fall within the scope of the present invention. In this embodiment, since the antenna 220 is placed in the detection gate 21〇, the degree and the placement position may affect the detection and reading of the RFID tag by the antenna 220, so the antenna 220 may be an activity in which the placement angle can be adjusted. The antenna, the movable antenna with adjustable position, or the movable antenna with the angle and the placement, can be adjusted at the same time to meet the requirements of the detection of the RFID tag. Figure 6 is a plan view of a radio frequency identification tag detecting platform 11 1326429 P65950003TW 20873twf.doc/n of the second embodiment of the present invention. Referring to Fig. 6, the RFID tag detecting platform 400 further includes a plurality of second conveying devices 500 connected to each other, wherein the second conveying devices 500 together with the first conveying device 3A constitute a circulating conveying device. In the present embodiment, these second conveying devices 500 include a plurality of linear conveying devices 510 and a plurality of steering conveying devices 6A. These steering conveyors 600 connect the first conveying device 3〇〇 with the second conveying devices 5〇〇 into a circulating conveying device, and allow the object 40 to repeatedly pass through the detecting gate 210 to detect the RF on the object 4〇 Identify the read rate of the tag. In addition, each linear transport device 510 and each of the steering transport devices 6 can provide different item delivery rates (Speed). Therefore, when the RFID tag detecting platform 400 detects the RFID tags of the plurality of objects simultaneously, the object conveying rate provided by the linear conveying device 510 and the steering conveying device 600 can control the distance between the objects 4〇. To avoid collision of the object 40. In addition, since the conveying speed of the linear conveying device 510 can be greater than that of the steering wheeling device 6 〇〇, by the object conveying rate of the linear conveying device 51 〇 and the steering conveying device 600, the object 4 〇, the linear conveying device can be made When the 510 is ready to enter the steering conveyor 6〇〇, it can be decelerated to prevent the rate of transporting the object 4 from being too fast to exit the RFID tag detection platform 400. Figure 7 is a schematic illustration of the construction of the steering conveyor of Figure 6. Referring to Fig. 7', the steering conveyor 600 includes a plurality of sets of rollers 61A, a steering conveyor belt 620, and a drive 63A. The set roller 61 〇 includes a drive roller 〕, at least one driven roller 614, and at least one drive belt 616. The driving roller 612 has a first driving portion 613a and a second driving portion 613b connected to the first 12 1326429 P65950003TW 20873twf.doc/n driving portion 613a. The driven roller 6i4 has a second driving portion 615a, a fourth driving portion 615b, and a universal joint 61 connected between the second driving portion 615a and the fourth driving portion 6151). The first driving portion 61% can be moved relative to the third driving portion 615a by the universal joint 615c, so that the first driving portion 613a and the third driving portion 61 are leveled, the second driving portion 6131) and the fourth driving portion. 61 is not parallel. The drive belt 616 is assembled with the first-carrying portion 613a and the third-carrying portion, and the steering belt 620 is assembled with the second entraining portion 613b and the fourth entraining member 615b. ° Fig. 8 疋 Fig. 7 is a sectional view of the Κ·Κ. Please refer to _ 7 and FIG. 8, drive 630 ·- drive shaft 634 卩 and a drive belt & to connect and drive the active roller 612 to rotate, so that the rotating active roller is driven by the transmission belt 616 The moving rollers 614 lie such that the set of shafts 600 are adapted to drive the steering conveyor belt 62〇. 'About the first-carrying portion 613a and the third-carrying portion 6 with = wear' to increase the p of the transmission belt 616. In addition, the first entraining portion 613a is parallel to the third entrainment, and fb is parallel to the riding quality, that is, the above Parallel = non-parallel caused by non-thinking (four) hitting, for example, at 612 and the driven roller 614, it is inevitable that there will be a slight non-parallel between the third portion 613a and the second driving portion 615a due to the error.
