The above embodiments are further understood through several application examples below.

Application example 1

This application example is realized based on the above-mentioned embodiment 1 and embodiment 4.

In this application example, the picking system includes a picking robot. There are several turnover boxes on the picking robot, and each turnover box is equipped with an RFID tag, which adopts the passive RFID tag with LED of Fasens Company, and the tag Two-dimensional codes or barcodes are also arranged on the top, which can be pasted.

The RFID reader/writer is used to read the RFID tag information on the turnover box, and is configured on the picking robot where it can read the RFID tag information on the turnover box.

The picking robot is equipped with an order analysis device, which is used to analyze the order, connect the barcode/two-dimensional code reading barcode device, and can read the barcode information of the product and the two-dimensional code information on the RFID on the turnover box, and the picking robot can Obtain order data and send it to the order analysis device.

Specifically, the picking robot obtains order data in real time or regularly through its own communication module (such as a WiFi wireless communication module), and transmits the order data to the order analysis device installed in the robot.

The warehouse manager uses the barcode reader of the picking robot to scan the barcode/QR code on the turnover box to bind the turnover box with the order information of the picking robot.

According to the order information in the order analysis device (including the QR code corresponding to the order number, all the products corresponding to the order number, the shelf positions of all the products, the quantity and size of the products, and other information), according to the shelf positions of the products respectively, you can Using the navigation and positioning methods in the prior art to make the picking robot automatically walk to the corresponding commodity shelf, or the warehouse manager walks to the corresponding commodity shelf according to the shelf number of the commodity, and the picking robot with the following function will follow the warehouse The management personnel walk to the front of the corresponding commodity shelf.

After arriving at the corresponding commodity shelf, the QR code information and RFID ID of the corresponding order are stored in the order analysis device, then the picking robot will send instructions to the RFID reader/writer, and the RFID reader/writer will read RFID information, the LED light in the RFID tag with the corresponding ID will flash to remind the warehouse manager to place the product in the turnover box with the LED light flashing, and there will be no error. The warehouse manager takes off the corresponding product and reads the product barcode on the barcode or two-dimensional code reader. After reading, the order analysis device recognizes that a corresponding product of the order is about to be put into the turnover box .

After all the products of an order are placed in the corresponding turnover boxes, after the order analysis device recognizes that the products belonging to the order have been scanned, the feedback is given to the robot, and the robot instructs the order analysis device to automatically enter the next order. Product information identification. Repeat the above process in turn.

Because this system uses passive RFID tags with LED lights, and there are two-dimensional codes on the labels, it establishes a one-to-one correspondence between orders, commodities, and two-dimensional codes, which can reduce manual picking and order goods Misplacement problems occur. Moreover, the label can be pasted on the turnover box by pasting, without laying circuits, etc., and the cost is low.

Application example 2

This application example is realized based on the above-mentioned embodiment 2 and embodiment 4.

In this application example, on the basis of application example 1, the difference from application example 1 is that passive RFID tags with LED lights are also set on the shelves. In this way, when the robot navigates to the location near the corresponding shelf according to the commodity shelf information in the order, the RFID reading device reads the ID corresponding to the corresponding shelf, and the LED light on the corresponding RFID label will flash to remind the warehouse manager (picker) Remove the item on the correct shelf.

Application example 3

The difference between this application example and application example 2 is that the passive RFID tags with LED lights set on the shelves are also connected to electronic counters to display the remaining quantity of goods on the shelves, and the electronic counters are connected to order analysis devices.

In another application example, the passive RFID tags with electronic counters set on the shelves are wirelessly connected to the robot, and the order analysis device feeds back the quantity information of the goods to the robot, and the robot sends commands to make the passive RFID tags with electronic counters The RFID tag shows the quantity that needs to be picked up.

Application example 4

This application example introduces a picking method based on RFID tags with LEDs and QR codes.

The picking method of this application example adopts the picking system of any application example in Application Example 1, Application Example 2, and Application Example 3, and the robot adopts a robot with an autonomous navigation and positioning system in the prior art, and the robot is provided with multiple Crate. The picking method of this application example comprises the following steps:

Step S01, each turnover box is provided with passive RFID tags with LED lights and two-dimensional codes, and each tag has a different ID;

Step S02, the robot autonomously navigates to the vicinity of the corresponding shelf according to the shelf information of the commodity in the order;

Step S03, the pick-up personnel use the barcode device to scan the graphic code on the turnover box to bind the order information with the ID of the RFID tag on the corresponding turnover box; the order analysis device feeds back the ID of the RFID tag on the turnover box corresponding to the order to The robot controls the RFID tag reading device to read the RFID, and the LED on the RFID tag with the ID flashes to prompt the pick-up personnel to put the product into the turnover box;

Step S04, the pick-up person takes off the commodity from the shelf, and scans it under the barcode scanning device, and the barcode scanning device feeds back the scanned commodity information to the order analysis device;

Step S05, after the operator finishes picking one commodity, pick the next commodity, and repeat steps S01-S04 until the corresponding commodity of the order is picked.

Correspondingly, after the goods picking of one order is completed, the picking of the next order also repeats the above steps.

The robot uses laser navigation, and other navigation and positioning methods can also be used. Of course, in order to realize the above functions, the robot first pre-stores the map in the warehouse.

Step S02 may also include: the robot autonomously navigates to the vicinity of the corresponding shelf according to the shelf information of the commodity in the order, the RFID reading device on the robot reads the RFID on the shelf, and the LED light of the RFID on the shelf storing the corresponding commodity flashes, Accurately remind the pick-up personnel to pick up the shelf.

Step S02 may also include: the warehouse manager picks up the goods according to the number of goods to be picked up displayed on the electronic counter, so as to avoid wrong number of goods to be picked up.

In addition, the robot can calculate the quantity of goods on the shelf based on the quantity of goods in the order and the quantity actually picked up by the warehouse manager, so as to remind replenishment when the quantity of goods is small.
