However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.
[0025] Example 1
[0026] See Figures 1-5 This utility model provides an RFID tag detection device, including a detection base 1. The detection base 1 adopts a metal frame structure and has a mounting groove for fixing the segmentation mechanism 4 and the transportation mechanism.
[0027] The base has a testing station in the middle, a testing mechanism 2 is installed above the testing station, and a material discharge area is reserved below.
[0028] The testing mechanism 2 includes a main control board 3, which is integrated inside the testing base 1 and contains a microprocessor, a signal processing module, and a wireless communication module, supporting real-time data interaction with external systems.
[0029] It also includes sensors, which use a combination of radio frequency (RF) sensors and optical sensors. The RF sensors are used to read RFID tag information, and the optical sensors are used to detect the position and size of materials. The sensors are connected to the main control board 3 through shielded wires to reduce signal interference.
[0030] It also includes an audible and visual alarm module, located on the side of the detection base 1, which includes a buzzer and an LED indicator, and is connected to the main control board 3 via wires or wireless connection.
[0031] The segmentation mechanism 4 includes a segmentation frame 401, which is fixed to both sides of the detection base 1 by bolts. A linear slide rail is installed on the segmentation frame 401, and the surface of the slide rail is coated with a lubricating coating.
[0032] The segmented push rod 402 is made of aluminum alloy and has an inclined surface 410 at the end with an inclination angle of 30°-45°. The segmented push rod 402 is slidably connected to the support slide 409 via a slider.
[0033] The drive mechanism includes a drive motor 403, which is a stepper motor, fixed to the top of the segment frame 401, and the output shaft speed is adjustable.
[0034] It also includes a cam 405, which is mounted on the output end of the drive motor 403, with an eccentricity of 10mm and a chrome-plated surface.
[0035] It also includes a rocker arm 406 and a connecting block 407. One end of the rocker arm 406 is hinged to the eccentric hole of the cam 405, and the other end is embedded in the arc-shaped matching groove 408 of the connecting block 407 through a pin. The connecting block 407 is bolted to the segmented push rod 402.
[0036] The actuation mechanism includes a pneumatic telescopic rod, which is vertically installed on the side of the testing station, with a telescopic stroke of 50mm and a response time of ≤0.5s.
[0037] The pneumatic telescopic rod is connected to an L-shaped push plate at its end. The plate has a rubber buffer layer on its surface and is hinged to the piston rod end of the pneumatic telescopic rod.
[0038] The transport mechanism includes a ring conveyor belt with anti-slip protrusions of 2mm height evenly distributed on its surface, and the transport speed is adjusted by a variable frequency motor.
[0039] It also includes a synchronization controller, which communicates with the main control board 3 to match the conveyor belt speed and the operating frequency of the segment push rod 402 in real time.
[0040] The working process of this utility model:
[0041] This utility model discloses an RFID tag detection device. In use, the material is transported to the detection area by a conveyor belt. Anti-slip protrusions prevent the material from sliding and deviating. Then, the drive motor 403 starts, the cam 405 rotates and drives the rocker arm 406 to swing, which in turn drives the slider to move in the support slide 409, thereby driving the segmented push rod 402 to extend. At the same time, through reciprocating regular movement, it performs precise and stable blocking and release. The inclined surface 410 of the segmented push rod 402 blocks subsequent materials, and the current material enters the detection station alone.
[0042] Tag detection: RF sensors read tag information, and optical sensors verify material position; main control board 3 analyzes the data, and if the information is complete and matches the preset value, it is judged as qualified.
[0043] For qualified materials, the pneumatic telescopic rod retracts, the conveyor belt continues to run, and the materials enter the next process.
[0044] For non-conforming materials, the main control board 3 triggers the pneumatic telescopic rod, which pushes the material into the discharge area; if there are 3 consecutive abnormalities, the audible and visual alarm module is activated and the conveyor belt is paused.
[0045] The segmented push rod 402 extends and retracts periodically during operation, and the conveyor belt synchronizes with the detection action to achieve continuous automated detection and sorting.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
