DETAILED DESCRIPTION

(9) In FIG. 1, a bar code 1 is die-cast on a hub outer rim 2.

(10) A laser head 5 emits laser, the laser passes through a first objective lens 4 and is transmitted to the hub surface bar code 1, and the laser refracted by the bar code 1 is transmitted to an image sensor 7 by a second objective lens 6. The first objective lens 4 and the second objective lens 6 are rotated at matching angles, and the laser is sequentially transmitted from left to right through a laser scanning trajectory 3 to the image sensor 7. The image sensor 7 records a height change value and transmits the height change value to a controller 8. The controller 8 converts the height change value into a bar code through an algorithm and reads the bar code information content. The controller 8 transmits the bar code information content to a computer 9.

Embodiment 1: Application of Die-Casting Workshop

(11) In FIG. 2, a roller bed 11 is rotated to transmit a die-cast bar code hub 12 to a position right above a laser engraving machine 10. A motor 13 drives a rotating arm 14 to rotate, and a laser reading means 15 reads the bar code information and transmits same to the computer. The computer identifies the wheel model, adds the wheel model production serial number information, and transmits the wheel model production serial number information to the laser engraving machine 10. The laser engraving machine 10 converts the information content into a two-dimensional code and etches the two-dimensional code to a hub flange weight reduction socket.

(12) Note: The die-cast hub rim is to be machined later, so the two-dimensional code position conversion is required.

(13) It can be realized: production quantity statistics, production time record, unique management and traceability of hubs; record of the production information of each hub about the process, device, personnel and the like; informatization of the die-casting workshop; zero delay transmission of information; quick aggregation of data, and automatic formation of a report formed for easy analysis.

Embodiment 2: Application of X-Ray Inspection Process

(14) In FIG. 3, the roller bed 17 is rotated to transmit a die-cast bar code hub 21 to move from left to right. The bar code information is read when the die-cast bar code hub 21 passes through a code reading device 18, and a hub model and a corresponding inspection device are determined. When the die-cast bar code hub 21 is determined to be the inspected device corresponding to second X-ray device 20, a sorting plate 23 is retracted, a stopper 24 is lowered, and the hub is transmitted to the second X-ray device 20. When the die-cast bar code hub 21 is determined to be the inspected device corresponding to first X-ray device 19, the stopper 24 is raised, a cylinder 22 pushes the sorting plate 23, and the sorting plate 23 pushes the hub, so that the hub is transmitted to the first X-ray device 19.

(15) It can realize: automatic screening of hubs, which overcomes the defects of misjudgment and the like when hubs are identified by front photographing in the past; inspection quantity statistics, inspection time record, unique management and traceability of the hubs; the X-ray device being programmed according to the product die classification, which reduces the problems of misjudgment, crash and the like caused by the die difference; zero delay transmission of information; quick aggregation of data, and automatic formation of a report formed for easy analysis.

Embodiment 3: Application of Machining Workshop

(16) In FIG. 4, a roller bed 26 is rotated to transmit a die-cast bar code hub 25 to move from left to right. The bar code information is read when the die-cast bar code hub 25 passes through the code reading device 27, and a hub model and a die number are determined. A machining lathe 28 calls a program for automatic machining according to the hub model and the die number.

(17) It can realize: automatic screening of hubs, which overcomes the defects of misjudgment and the like when hubs are identified by front photographing in the past; production quantity statistics, production time record, unique management and traceability of the hubs; record of the production information of each hub about the process, device, personnel and the like; the machining device being programmed according to the product die classification, which reduces the problems of crash, out of tolerance and the like caused by the die difference; zero delay transmission of information; quick aggregation of data, and automatic formation of a report formed for easy analysis.
