Design and experimental study of automatic bead gluing mechanism

Many tire factories generally use manual methods for bead gluing in the assembly process of tires and wheels. The gluing efficiency is low and there are problems such as uneven gluing and low pass rate, which has always been one of the problems faced in the tire assembly process. It also brings about a lot of waste in mass production. In addition, in order to meet the needs of mass production, the automation of tire production is imminent. This paper investigates the tire factories and finds that the mesh belt chain with additional rollers is used as the conveying unit in view of the characteristics of large frictional resistance and difficult operation of tires. The gluing roller increases the load-bearing roller to increase the strength and rigidity and the rotating mechanism and the blocking mechanism are combined into one, which reduces the complexity of the mechanism, and uses the anti-parallelogram linkage mechanism to achieve relative swing, making the gluing equipment compact in structure and high in efficiency. Finally, the method verified by the prototype experiment was tested in the factory, which improved the first pass rate of the product, reduced the number of reworks, reduced the number of labor force, and effectively reduced the production cost. Bead coating is an important process in the assembly of tire and rim, which is related to the air tightness after assembly. In addition to the low efficiency of manual assembly brush, the uneven brush has always been the weak link of tire assembly. Aiming at the characteristics of high friction resistance and difficult operation of tire, this design uses the mesh belt chain with additional roller as the conveying unit. The coating roller increases the load-bearing roller, increases the strength and rigidity, and the rotating mechanism and the blocking mechanism are combined to reduce the complexity of the mechanism. The antiparallel-crank mechanism is used to realize the relative swing, which makes the coating equipment compact, efficient and smooth.
