Description

Technical Field

[0001] The utility model relates to the technical field of conveying automobile subframe products, in particular to a transfer and conveying device for automobile subframe products. Background Art

[0002] In the manufacturing of modern automobiles, the chassis subframe plays an important role, not only supporting the structure of the entire vehicle, but also bearing heavy loads. During the production process, the preparation of the chassis subframe consists of multiple processes, and the chassis subframe needs to be transferred to each process for processing. However, due to the limitation of site space, some process layouts are non-linear.

[0003] At present, non-linear conveying devices usually adopt a conveying structure of a two-stage conveyor belt. The first section of the conveyor belt conveys the product to the corner along the conveying direction of the conveyor belt, and at the corner, the product is sent to the second section of the conveyor belt after the corner, and the second section of the conveyor belt continues to convey the product. Although the conveying device changes its angle, the direction of the product itself does not change. This conveying structure is only suitable for conveying small-sized products. However, for rectangular product structures such as automobile subframes, when conveying on the first section of the conveyor belt, the long side of the product is parallel to the longitudinal direction of the conveyor belt for conveying, so as to reduce the width of the conveyor belt and the footprint of the conveyor device. When the product reaches the corner and enters the second section of the conveyor belt, the product itself cannot change direction. The short side of the product is parallel to the longitudinal direction of the second section of the conveyor belt, and the long side corresponds to the wide side of the conveyor belt. If the long side length of the product is used as the width of the conveyor belt, the width of the conveyor belt must be made very large, which not only increases the footprint of the conveyor device, but also increases the difficulty of making the conveyor device. In addition, the increase in the bandwidth of the conveyor belt also increases the material cost of the conveyor device, increasing the burden on the enterprise. If the transfer between non-linear processes such as automobile subframes is done manually, the chassis subframes may be damaged due to the instability of manual handling. In addition, the chassis subframes are heavy and usually require multiple people to carry them, which is time-consuming and labor-intensive. Manual handling is high in intensity and low in efficiency, resulting in high handling costs. How to solve the transfer of automobile chassis subframes in non-linear processes has long been a difficult problem to solve. Summary of the invention
