[0002] In the automobile manufacturing production process, it is required to read the car body bar code (such as transfer station, bifurcated route, paint booth and the like) at important passing points to obtain / verify the car body information. Since the relative positions of bar codes of different vehicle models relative to conveying carriers (such as ETS, topcoat skid, electrophoresis skid and the like) are different, a single code reading device cannot cover multiple vehicle models, and therefore the prior art adopts multiple code reading devices installed at different positions to scan different vehicle models. This makes it necessary to add code reading devices at all code scanning points when a new vehicle model is produced, which results in large changes, high cost and long time required. Taking a project as an example, there are 30 code scanning points in welding, painting, corridor and stereoscopic warehouse, and general assembly, and therefore 30 code reading devices need to be added.

[0003] In addition, the steel code is a rectangular lattice composed of small pits with a depth of about 0.3 mm engraved on the surface of the steel plate of the vehicle body by a needle engraving device. Among all one-dimensional and two-dimensional bar codes, the steel code is the most difficult to identify, and has a high requirement for the scanning position of the code reading device.
