[0033] The detection device includes an RFID (Radio Frequency Identification) reader and a QR code reader. The RFID reader is used to verify the RFID number and quantity of the products in the box body 17, and the QR code reader is used to scan the QR code on the box body 17 to identify the box number of the box body 17. The RFID reader in this embodiment includes multiple RFID antennas, and the RFID antennas are equipped with high-precision radio frequency acquisition integrated modules to obtain the chip RFID information on the products in the box body 17. The multiple RFID antennas are respectively installed above different areas inside the shielding cover.

The QR code reader is a barcode scanner, and the barcode scanner is installed at a corresponding position inside the shielding cover according to the position of the QR code on the box body 17. By scanning the QR code on the box body 17 multiple times, the barcode scanner can not only efficiently and accurately ensure the identification and reading of the box number of the box body 17, but also be applicable to the classification scanning of other diverse products. Preferably, the RFID antenna is a high-power RFID antenna with a power of not less than 20W, and the QR code reader is a high-resolution barcode scanner with a resolution higher than 0.15mm.
[0034] The third optoelectronic device 7 and the fourth optoelectronic device 8 are installed on the verification platform 10 at a predetermined interval along the conveying direction of the second conveyor belt 12.

According to the trigger signal of the photoelectric sensor, the industrial control module controls the start and stop of the corresponding section of the belt. In this embodiment, the first belt 2, the second belt 12 and the third belt 15 can be started and stopped respectively according to the movement requirements of the box 17, ensuring that there is and at most only 1 box 17 on each section of the belt. While improving the automation degree of the calibration device, the energy consumption of the entire calibration device is reduced, and the placement spacing control of the boxes 17 on each section of the belt, as well as the status alarm control such as the box 17 being skewed, stuck, continuously placed, and the reminder of long-term storage of the received box, etc. are realized according to the start and stop of each section of the belt. The RFID processing module is connected to the RFID antenna, receives the detection information of the RFID antenna, adds up the product quantities collected by the 4 RFID antennas to calculate the product quantity in the box 17, and determines the product information in the box 17. This actual product quantity and product information are transmitted to the industrial control module to compare with the predetermined product quantity and product information of the box 17 with this box number. If they are consistent, the calibration is qualified; otherwise, it is unqualified.

The operator inputs control commands and views calibration data to the industrial control module, the distribution board, etc. through the touch screen. The real-time monitoring of the image sensor facilitates the industrial control module to detect abnormal phenomena in a timely manner, such as the box 17 being skewed, stuck, continuously placed, etc.
[0036] The blanking component of this embodiment includes a fifth photoelectric sensor 13, a second centering guide rail 14, a third belt 15, and a blanking platform 16. The blanking platform 16 is coaxially located on the output side of the calibration platform 10 along the conveying direction. The third belt 15 is a box receiving belt, which is installed on the blanking platform 16, coaxially flush with the second belt 12 and has the same conveying direction, and is used to convey the box body 17 within the blanking component. The structure and installation method of the second centering guide rail 14 are the same as those of the first centering guide rail 4. Two second centering guide rails 14 are arranged in parallel on the front and rear sides of the third belt 15 and are centered and moved by a cylinder, which will not be elaborated here. The fifth photoelectric sensor 13 is installed at a predetermined position on the blanking platform 16 and is used to monitor whether the box body 17 reaches the third belt 15. When the fifth photoelectric sensor 13 is triggered by a signal for a predetermined duration, it indicates that the box body 17 reaches the box receiving position.
[0037] The calibration process of the calibration device in this embodiment is as follows:
[0038] 1. Loading;
[0039] Manually or automatically, a conveying mechanism picks up the box body 17 with the QR code pasted and places it on the first belt 2. When the first photoelectric sensor 3 triggers the photoelectric signal for more than a predetermined time, the industrial control module determines that the box body 17 reaches the calibration waiting area. At this time, the feed shielding door 6 and the discharge shielding door 9 are in the open state;
[0040] 2. Conveying the box body 17 to the calibration area;
[0041] The industrial control module controls the first belt 2 and the second belt 12 to start running according to the box body in-place signal, and conveys the box body 17 to the calibration area inside the shielding cover. And the attitude of the box body 17 is controlled by the first centering guide rail 4 during the conveying process. The box body 17 passes through the positions of the second photoelectric sensor 5 and the third photoelectric sensor 7 in sequence. When the fourth photoelectric sensor 8 is triggered, the industrial control module controls the first belt 2 and the second belt 12 to stop, and closes the feed shielding door 6 and the discharge shielding door 9;
[0042] During the continuous calibration process, the calibration device ensures that there is at most 1 box body 17 on each section of the belt through the second photoelectric sensor 5, the third photoelectric sensor 7, the fifth photoelectric sensor 13, and the industrial control module.
[0043] 3. Calibrating the product;
[0044] After the feeding shielding door 6 and the discharging shielding door 9 are completely closed, the industrial control module starts the barcode scanner and the RFID reader. The barcode scanner starts to scan the QR code on the box body 17 for code reading and sends the information to the industrial control module to determine the box number. The RFID reader reads the chip information of the products in the box body 17 and records the quantity of the products, and sends the information to the RFID processing module for verification. The RFID processing module obtains the box number information through the industrial control module, and judges whether the RFID information and quantity of the products in the box body 17 are correct; and alarms through the voice alarm to inform the operator of the verification result of the current box body 17, and at the same time sends a verification completion signal to the industrial control module.
[0045] 4. Transport the box body 17 out of the shielding cover;
[0046] After the verification is completed, the industrial control module controls the feeding shielding door 6 and the discharging shielding door 9 to open automatically; after the shielding doors are completely opened, the industrial control module automatically starts the second belt 12 and the third belt 15 to run, and transports the box body 17 in the verification component to the blanking component.
[0047] 5. Receive the box.
[0048] When the box body 17 runs onto the third belt 15 and the fifth optoelectronic sensor 13 is triggered, the industrial control module controls the third belt 15 to stop running. When the fifth optoelectronic sensor 13 detects that the box body 17 has been stationary for more than the set duration, the voice alarm alarms to prompt to remove the box body 17; the industrial control module controls the first belt 2 to run, and automatically runs the box body 17 on the first belt 2 to the next process, and the above verification process is cycled.
