Technical Field

The invention mainly relates to the field of conveying equipment, in particular to an automatic conveying device of a production line.

Background

Compared with the common single-piece production, the flow operation on the production line has more detailed division, and each worker only needs to complete one or more procedures, so that the effective operation time of the worker is longer, and the production efficiency is greatly improved. At present, assembly line conveying equipment is only used for conveying semi-finished products, the speed of each process is not considered, workers still need to move the semi-finished products to stations in front of the workers to operate, the physical power and time of the workers are consumed in repeated conveying, and the efficiency is reduced. Although a stepping type conveying apparatus has been introduced in a factory, once a worker fails to complete a process at a predetermined time due to individual differences, the conveying apparatus conveys a semi-finished product to a next process, which is a problem, and such a stepping type conveying apparatus is not practical in actual production.
