Description

Technical Field

[0001] This invention relates to the field of steel coil label scanning technology, specifically to a scanning device and scanning method for steel coil conveying lines. Background Technology

[0002] Taking a cold-rolled steel coil production line as an example, after a cold-rolled steel coil is processed in the upstream unit, its information (such as steel grade, specifications, production date, etc.) needs to be printed as a barcode / QR code label. This label is then manually or automatically affixed to a relatively fixed position on the surface of the steel coil before it is transported to the downstream unit. Simultaneously, the label on the steel coil needs to transmit the coil information to the downstream unit during transportation. Currently, this process is mainly handled in two ways: 1. Manual handheld industrial barcode scanners are used to scan the label codes. The barcode scanners transmit the information to the downstream production line via wireless Bluetooth or other means.

[0003] 2. An industrial six-axis robot equipped with a camera is used to scan the label code and then send the steel coil information to the downstream production line through a wired interface.

[0004] The disadvantage of method 1 is that it increases the intensity of manual labor, and the wireless barcode scanner is easily interfered with during signal transmission due to the large number of wireless signals in the factory. The disadvantage of method 2 is that the price of industrial six-axis robots is too high, resulting in excessive investment costs. Summary of the Invention

The steel coil occupancy detection mechanism is used to identify whether a steel coil has been conveyed to the steel coil detection area, the steel coil rotation mechanism is used to drive the steel coil located in the steel coil detection area to rotate, and the barcode scanning camera is located above the steel coil occupancy detection mechanism. The barcode scanning camera is used to scan and identify the label code on the steel coil located in the steel coil detection area and transmit the scanned label code information to the computer system for display.

[0007] Preferably, it also includes a fixed bracket, which includes a vertical pole and a horizontal bar located at the top of the vertical pole and extending horizontally to one side, with the barcode scanning camera mounted on the horizontal bar.

[0008] Preferably, the steel coil rotating mechanism includes a motor and a steel coil rotating roller connected by a drive. The motor drives the steel coil rotating roller to rotate, thereby causing the steel coil located on the steel coil rotating roller to rotate.

[0009] Preferably, the steel coil is a horizontal steel coil with a width ranging from 900 to 2000 mm and an outer diameter ranging from 900 to 2150 mm.

Place the steel coil horizontally onto the conveyor line and convey it forward through the conveyor line; S2. The steel coil continues to be conveyed forward. The steel coil triggers the steel coil occupancy detection mechanism, thereby confirming that the steel coil has entered the steel coil detection area. The steel coil rotation mechanism then starts the barcode scanning camera. S3. The steel coil rotation mechanism drives the steel coil located in the steel coil detection area to rotate, thereby aligning the label code on the steel coil with the barcode scanning camera. The barcode scanning camera scans and identifies the label code on the steel coil in the steel coil detection area and transmits the scanned label code information to the computer system.

[0012] The present invention has the following beneficial effects: This invention enables rapid and automatic scanning and identification of the label codes on steel coils on the steel coil transport line through the coordinated operation of a steel coil rotation mechanism, a steel coil positioning detection mechanism, and a barcode scanning camera. The scanned label code information is then transmitted to a computer system for display. This eliminates the need for manual scanning with an industrial barcode scanner, reducing labor intensity and costs. Furthermore, the wired interface of the camera prevents interference during transmission, ensuring transmission stability. Compared to the scanning method of an industrial six-axis robot, this invention offers lower investment costs and higher cost-effectiveness. Attached Figure Description

[0024] In this embodiment, the steel coil 8 is a horizontal steel coil, that is, the axial direction of the steel coil 8 is a horizontal direction that is perpendicular to the conveying direction. In other words, the conveying direction is the front-to-back direction, and the axial direction of the steel coil 8 is the left-to-right direction, thereby ensuring the smooth and stable operation of the steel coil 8 conveying and scanning.
