Description

Technical Field

[0001] The present invention relates to the technical field of painting equipment, and specifically relates to a painting line for shaft parts with a truss robot and horizontal and vertical access to the chamber body. Background Art

[0002] Currently, as long as the production capacity of a paint production line (i.e., a painting line) has a certain scale, almost all of them use traditional conveyors to form a "line" in the broad sense of a one-dimensional space, that is, functional chamber bodies such as spray booths, leveling chambers, drying chambers, and strong cooling chambers are strung into a conveying system of a "broad one-dimensional space" according to process routes such as pretreatment, primer, the first topcoat, and the second topcoat. For example, in the air, traditional conveyors such as suspension chains, accumulation chains, and self-propelled trolleys are generally used; on the ground, conveying methods such as plate chains plus translation or rotation, reverse accumulation chains, and RGV vehicles are generally used.

[0003] Although in some traditional paint production lines, elevators and other conveying methods are occasionally used at certain specific locations, in essence, it is still a conveying system of a "broad one-dimensional space" composed of "lines" (conveyor lines), rather than a true three-dimensional space conveying system.

[0004] Just like the railway transportation system, only from the narrow physical concept, the railway network is indeed three-dimensional in space, but if there is no track connection, even if the trains are only one meter apart, they cannot reach. Therefore, from the broad concept, the railway network system can still be regarded as a "broad one-dimensional space" system composed of "lines" (tracks).

[0005] Traditional paint production lines are like railway vehicles that can only run on "one-dimensional" tracks, while truss robots can run in a "three-dimensional space" like airplanes.

[0006] If the shaft parts to be transported are regarded as "points", then the "points" can only find a running path in the established "one-dimensional space" composed of "lines". Without a conveyor line, no matter how close the equipment is, the shaft parts cannot reach; moreover, most production lines can only run in one direction, and once the production line is built, it will be extremely difficult to change the process route. Therefore, the main disadvantages of traditional shaft part paint production lines are: complex structure, difficult equipment layout, large floor area, and high cost. Summary of the Invention
