Description

Technical Field

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

[0002] At present, as long as the production capacity of a paint production line reaches a certain scale, it almost always uses traditional conveyors to form a "line" in the broad sense of a one-dimensional space, that is, functional chambers 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 carts 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 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 workpiece to be transported is regarded as a "point", then the "point" 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 workpiece 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 spreader 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. The conveyor 2 includes a track 2A and a traction device 6. The spreader car 5 includes a car body 5A, a spreader device 5B, and a grasping interface 5C.

[0012] As a further solution of the present invention: The track 2A includes a channel steel track 2A1. The traction device 6 includes a traction chain 6A and a pusher head 6B installed on the traction chain 6A. The pusher head 6B pushes the car body 5A forward.

[0013] As a further solution of the present invention: The length of the car body 5A is greater than the length of the workpiece 1. The conveyor 2 includes an accumulation car body conveyor 7.
