Description
Technical Field
[0001] The present invention relates to the technical field of tire conveying, and in particular to intelligent suspension conveying equipment for tire production. Background Art
[0002] With the rapid development of the new energy vehicle manufacturing industry, production efficiency, product quality, and cost control have become key factors for companies to stand out in the fierce market competition. The intelligent tire conveying process plays a vital role in the entire new energy vehicle production chain. It is like an indispensable link in the chain, closely connecting all aspects of production. Especially in the inspection process, due to the weight of the battery pack, new energy vehicles are heavier overall, and the tires need to bear more weight, so there are more inspection links. The existing intelligent suspension conveying system can efficiently and accurately transport vulcanized tires to a dedicated inspection line for comprehensive and rigorous quality inspection, ensuring that each tire meets the established quality standards and meets the market demand for high-quality new energy vehicles.
[0003] During the transportation of tires, they are usually suspended on a special intelligent conveying device for efficient and stable transportation. However, in the actual transportation process, since the conveying line is often not a straight line layout, but has multiple corners, when the tire is transported to these corners, the tire will rotate a certain angle along the intelligent conveying line. In addition, the suspension state makes the tire prone to shaking when subjected to external forces. Therefore, at the corners, the suspended tires often have more obvious shaking. This shaking may not only cause the tire to deviate to a certain extent, but may even cause the tire to fall from the suspension device, thereby seriously affecting the efficiency and quality of transportation.
