Automobile coating conveyor based on series-parallel hybrid mechanism

Abstract

The invention relates to an automobile coating conveyor based on a series-parallel hybrid mechanism and belongs to the field of machine manufacturing and traffic transportation. The conveyor comprises two functional components including a portal frame and a parallel conveying mechanism. The parallel conveying mechanism comprises two symmetrically arranged parallel mechanisms which are connected to the two sides of the portal frame correspondingly and connected into a whole through a connecting rod. The position and gesture of an automobile body are adjusted through synchronous movement of the parallel mechanisms. The portal frame can move along a supporting seat, the portal frame and the parallel conveying mechanism cooperatively move to form the hybrid mechanism, and thus conveying of the automobile body on a coating production line is achieved. Since the advantages of high rigidity and high dynamics load bearing capacity of the parallel mechanisms are utilized by the conveyor, the conveyor is higher in adaptability, coating of automobile bodies of different types and sizes can be completed on the production line, and flexible production is achieved.

Description

technical field [0001] The present invention relates to the field of machinery manufacturing and transportation, specifically an automobile coating conveyor based on a series-parallel hybrid mechanism Background technique [0002] The painting process is a very important process link in automobile manufacturing. The advanced nature of the painting process will directly affect the overall quality of the car. In the painting production line, the body is fixed on the conveyor, and the movement of the car body is realized through the movement of the conveyor. The painting conveyor runs through the whole process of the painting production line for actions such as lifting and turning, and its performance directly affects the painting quality of the car body. The traditional suspended conveyor is the first conveyor equipment to be applied in the automobile production line, but the suspended conveyor has defects such as easy contamination of the electrophoretic fluid and air pockets...

Problems solved by technology

However, RoDip conveyors and multifunctional shuttles have complex structures, high equipment investment, operation and maintenance costs

In addition, RoDip conveyors and multi-functional shuttles also have certain structural defects. Both of them adopt cantilever structures, and the cantilever beams are difficult to bear heavy loads. Therefore, a single machine is only suitable for electrophoretic coating of small cars, which is difficult to meet The flexible production requirements of different vehicle models in the painting production line

For example, in order to paint large and heavy car bodies, two multifunctional shuttle machines need to be used at the same time (refer to Chinese invention patent 200410003154.2), which leads to complicated control, low efficiency and high cost
