Description

Technical Field

[0001] The present invention relates to the technical field of painting equipment, and specifically to a paint production line for disc-shaped parts with a truss robot and a vertical access chamber body. 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 chamber bodies such as each spray booth, 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 elevators and other conveying methods are occasionally used at certain specific locations in traditional paint production lines, in essence, it is still a conveying system of a "broad one-dimensional space" composed of "lines" (conveyor lines), rather than a three-dimensional space conveying system in the true sense.

[0004] Just like the railway transportation system, only understood 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, understood 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 disc-shaped parts 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, no matter how close the equipment is, the disc-shaped 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 paint production lines for disc-shaped parts 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 for disc-shaped parts with a truss robot and a vertical access chamber body to solve the problems mentioned in the above background art.

Mandrel 5A enters a set position inside vertical chamber 3A through indoor conveying device 3E. After disc part 1 completes the set operation, mandrel 5A reaches indoor tail end 3E2 through indoor conveying device 3E again, and then truss robot 4 hoists mandrel 5A to other set positions, that is, disc part 1 realizes its conveyance between all or part of the vertical chamber modules 3 through truss robot 4.

[0009] As a further solution of the present invention: The indoor conveying device 3E includes a chain conveyor 6.

The spacing between several adjacent fixed V-shaped grooves 3A1V on fixed seat 3A1 is equal to the spacing between several adjacent movable V-shaped grooves 7A1 on movable rod 7A. When movable rod 7A is at the lowest position, movable V-shaped groove 7A1 is lower than fixed V-shaped groove 3A1V. Movable rod 7A can run below mandrel 5A on fixed V-shaped groove 3A1V through push-pull device 7C. When movable V-shaped groove 7A1 is aligned with fixed V-shaped groove 3A1V in the vertical direction and movable rod 7A rises to the highest position through lifting device 7B, movable rod 7A can lift mandrel 5A away from fixed V-shaped groove 3A1V, move forward by a spacing through push-pull device 7C, and then lower through lifting device 7B, and place mandrel 5A on movable V-shaped groove 7A1 on fixed seat 3A1 into fixed V-shaped groove 3A1V.
