Description

Technical Field

[0001] This utility model relates to an RGV trolley, and more particularly to a barcode reader that can read the QR code of logistics information on a plate-shaped vehicle. Background Technology

[0002] In a logistics warehouse, storage areas for various goods are typically arranged in zones. Each storage area is equipped with a conveyor line responsible for sending out or storing goods within that area. Connecting zones are set up between different conveyor lines. RGV (Automated Guided Vehicle) carts travel back and forth within these zones, connecting with different conveyor lines to transfer goods. Goods on each conveyor line are generally transported via pallets, each equipped with a logistics information QR code. When an RGV cart connects with a conveyor line, the goods on that line are transferred to the RGV cart. Simultaneously, the barcode reader on the RGV cart reads the logistics information QR code, identifies it, and determines the destination. The RGV (Gallery Vehicle) trolley starts, transporting the transferred goods to the target docking point for docking and transfer, thus completing the transfer task. Existing logistics information QR codes are generally placed on the side of the pallet carrier, with a corresponding barcode reader on the RGV trolley. However, some goods are stacked in plate form with varying sizes. For these goods, traditional pallet carriers cannot be used; only plate carriers can be used. The logistics information QR codes on plate carriers lie flat on the top surface, making them unreadable by traditional barcode readers. Furthermore, the greater width of the goods causes interference between the transfer path and the barcode reader on the RGV trolley. Developing an RGV scanning device specifically designed for this situation is a problem that needs to be solved on-site. Summary of the Invention

[0004] This utility model solves the above technical problems through the following technical solution: A barcode reader for reading logistics information QR codes on a plate-shaped carrier includes an RGV trolley, on which a plate-shaped carrier is mounted. A stack of plate-shaped materials is placed on the plate-shaped carrier. A logistics information QR code is located on the top surface of the plate-shaped carrier outside the stack of plate-shaped materials. A barcode reader bracket is mounted on the RGV trolley, and a barcode reader device is mounted on the barcode reader bracket. The barcode reader device consists of a rotary screw module, a horizontal cantilever guide rail, a movable vertical L-shaped slide, a horizontal L-shaped slide, and a barcode reader.

A horizontal cantilever guide rail is connected to the U-shaped bracket. A movable vertical L-shaped slide is connected to the horizontal cantilever guide rail. A horizontal L-shaped slide is connected to the upright plate of the movable vertical L-shaped slide.

Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings: A barcode reader for reading logistics information QR codes on a plate-shaped carrier includes an RGV trolley 1, on which a plate-shaped carrier 3 is mounted. A stack of plate-shaped materials 4 is placed on the plate-shaped carrier 3, and the plate-shaped carrier 3 carries the stack of plate-shaped materials 4 for transfer and transportation between the RGV trolley 1 and a cargo conveyor line 7. A logistics information QR code 5 is provided on the top surface of the plate-shaped carrier 3 outside the stack of plate-shaped materials 4. A barcode reader bracket 8 is provided on the RGV trolley 1, and a barcode reader device 6 is provided on the barcode reader bracket 8. The barcode reader device 6 consists of a rotary screw module 9, a horizontal cantilever guide rail 13, a movable vertical L-shaped slide 14, a horizontal L-shaped slide 18, and a barcode reader 21. The rotary screw module 9 is driven by a rotary screw drive motor 10. The motor 10 drives the lead screw in the rotary lead screw module 9 to rotate, thereby moving the nut seat 11 on the lead screw left and right. A U-shaped bracket 12 is fixedly connected to the nut seat 11 of the rotary lead screw module 9. A horizontal cantilever guide rail 13 is connected to the U-shaped bracket 12. The horizontal cantilever guide rail 13 moves left and right under the drive of the nut seat 11, realizing extension and retraction. A movable vertical L-shaped slide 14 is connected to the horizontal cantilever guide rail 13. The movable vertical L-shaped slide 14 can be adjusted on the horizontal cantilever guide rail 13 to realize the alignment adjustment of the barcode reader with the logistics information QR code 5 on the top surface of the flat carrier 3. A horizontal L-shaped slide 18 is connected to the upright plate of the movable vertical L-shaped slide 14. A barcode reader 21 that can read the logistics information QR code 5 is set on the horizontal L-shaped slide 18.

[0010] A first transverse elongated through hole 15 is provided on the horizontal plate of the movable vertical L-shaped slide 14. The fixing screw 16 passes through the first transverse elongated through hole 15 and abuts against the horizontal cantilever guide rail 13, thereby fixing the movable vertical L-shaped slide 14 after the position is adjusted. A vertical elongated through hole 17 is provided on the upright plate of the movable vertical L-shaped slide 14. A second transverse elongated through hole 22 is provided on the connecting plate of the horizontal L-shaped slide 18. A connecting bolt 19 passes between the vertical elongated through hole 17 and the second transverse elongated through hole 22. The horizontal L-shaped slide 18 adjusts the height of the barcode reader 21 by moving up and down along the vertical elongated through hole 17. The position of the connecting bolt 19 is adjusted in the second transverse elongated through hole 22 to adjust the front and back position of the barcode reader 21.

[0011] An arc-shaped through hole 20 is provided on the mounting plate of the horizontal L-shaped slide 18. The base of the barcode reader 21 is movably connected in the arc-shaped through hole 20. By adjusting the position of the base of the barcode reader 21 in the arc-shaped through hole 20, the reading angle of the barcode reader 21 can be adjusted. The RGV trolley 1 is docked on the cargo conveyor line 7. A cargo conveying roller 2 is provided on the vehicle platform of the RGV trolley 1, and a flat plate carrier 3 is movably mounted on the cargo conveying roller 2.

[0012] When the flatbed carrier 3, loaded with a stack of plate-shaped materials 4, is transferred to the cargo conveying roller 2 on the body platform of the RGV trolley 1, the rotary screw drive motor 10 starts, driving the nut seat 11 to move towards the center of the trolley. The horizontal cantilever guide rail 13 extends towards the center of the trolley, causing the barcode reader 21 on the mounting plate of the horizontal L-shaped slide 18 to move directly above the logistics information QR code 5 on the top surface of the flatbed carrier 3. After reading the logistics information QR code 5, the rotary screw drive motor 10 rotates in the opposite direction, causing the horizontal cantilever guide rail 13 to retract towards the outside of the trolley, clearing the way for the transfer and output of the flatbed carrier 3 loaded with a stack of plate-shaped materials 4. The RGV trolley 1 then transfers the goods to the destination cargo conveyor line 7 according to the read logistics information QR code 5.
