A tire is a circular ring-shaped rubber product used in various vehicles or machines. Tires are usually used under complicated and severe conditions, which are subjected to various deformations, loads, forces and high and low temperatures during running, and therefore must have high load-bearing, traction and cushioning properties, as well as high wear resistance and flexibility, and low rolling resistance and heat buildup. The production of tyres generally requires the following steps: banburying process, rubber part preparation process, extrusion, calendering, bead forming, cord fabric cutting, bead apex attaching, belt ply forming, tire forming process, vulcanization process, final inspection process and tire testing.

In the production process of the tire, code scanning operation is carried out on the tire in and out of a warehouse, namely, corresponding bar codes are printed on the surface of the tire, and identity information of the tire can be acquired through the code scanner and then is subjected to subsequent processing; because the bar code is printed on the side surface of the tire, the tire can be randomly placed on a production line when the tire runs on the production line, but the bar code cannot appear on a specific certain position, so that the efficiency of subsequent operation is influenced.

In addition, in the tire production process, because the thickness of the rubber material affects the quality of the tire, in order to make the weight of the tire with the same specification the same, the weight of the tire with the same specification needs to be detected, the qualified tire and the unqualified tire with the same specification are sorted, and the unqualified tire is recycled to be rebuilt.
