Description

Technical Field

[0001] The present invention relates to the technical field of painting equipment, and specifically to a paint production line with a truss robot and a sling cart. Background Art

[0002] Currently, as long as the production capacity of a paint production line reaches 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 chambers such as each painting chamber, leveling chamber, drying chamber, and strong cooling chamber 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, conveying methods such as elevators 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 the "three-dimensional space" like airplanes.

[0006] If the workpieces to be transported are regarded as "points", then the "points" can only find running paths in the established "one-dimensional space" composed of "lines". Without conveyor lines, even if the equipment is very close, the workpieces 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 paint production lines for workpieces are: complex structure, difficult equipment layout, large floor area, and high cost. Summary of the Invention

[0007] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a paint production line with a truss robot and a sling cart to solve the problems mentioned in the above background art.

[0008] To achieve the above object, the present invention provides the following technical solutions: The paint production line of the workpiece 1 includes a truss robot track 1X, a conveyor 2, a truss robot 4 running on the truss robot track 1X, and a spreader car 5.
