Description

Automobile part picking and placing rack

Technical Field

The utility model relates to an automobile parts field, more specifically say, relate to automobile parts get work or material rest.

Background

On the automobile production assembly line, each station is installed and processed fixed spare part by the robot, consequently, all need dispose spare part on each station and get the work or material rest, places the spare part that this station corresponds on the work or material rest and takes with the robot altogether.

On traditional automobile production assembly line, each assembly line corresponds a motorcycle type, and every station all corresponds a spare part. Therefore, the traditional part picking and placing rack adopts a fixed structure. And designing a material rack structure according to the shape, the size and the material property of the corresponding automobile parts. The material racks are all integral steel pipe welding racks. The welded structure cannot be changed, and each material rack can only be suitable for automobile parts with one overall dimension.

Moreover, in order to satisfy consumers with different preferences, automobile manufacturers may develop multiple vehicle models on the same platform. On the other hand, in order to save the manufacturing cost, the vehicle models based on the same platform can share the production line to realize collinear production. When collinear production is carried out, corresponding parts of different vehicle types can be processed on the same station, the parts of different vehicle types are slightly different in shape, size, material and the like, and the challenge brought to the mode of the existing fixed material rack is brought. Because under the mode of fixed work or material rest, work or material rest and spare part one-to-one, the spare part that the shape size slightly differs also can lead to unable loading to the work or material rest, and this just needs all make the work or material rest respectively for every kind of spare part. In general, the conventional stationary rack mainly presents the following problems:

a) in case the motorcycle type changes, perhaps newly-increased motorcycle type, just need increase a work or material rest, the matching of work or material rest and motorcycle type is the one-to-one. When motorcycle type quantity increases very fast, can cause work or material rest quantity to increase fast, no matter be manufacturing cost or take up space and all can increase by a wide margin.

b) The material rack has various dimensions and specifications, and cannot meet the storage requirements of the current standard elevated stereoscopic warehouse.
