Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of painting equipment, and specifically, it is a paint production line with a truss robot and a spreader capable of longitudinal and lateral movement. 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, various functional chambers 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 "broad one-dimensional space" conveying system 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. However, if there is no track connection, even if the trains are only one meter apart, they cannot reach each other. 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, even if the equipment is very close, the workpiece cannot reach it; 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 workpiece paint production lines 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 capable of longitudinal and lateral movement to solve the problems mentioned in the above background art.

The entrance of the starting section 3A and the exit of the ending section 3B are both open. The truss robot 4 can grasp the spreader 5 carrying the workpiece 1 and enter the narrow conveyor 3 from the starting section 3A, or grasp the spreader 5 carrying the workpiece 1 from the ending section 3B and leave the narrow conveyor 3.
[0009] As a further solution of the present invention: Both the wide conveyor 2 and the narrow conveyor 3 include a double-plate chain conveyor 6.

[0011] As a further solution of the present invention: The grasping interface 5C includes a hanging hole 5A2 on the hanger 5A or the bottom edge of the hanger 5A.

By inserting the translational jaw 4A1 into the hanging hole 5A2 or clamping the bottom edge of the hanger 5A, the truss robot 4 realizes the picking and placing of the spreader 5.
[0012] As a further solution of the present invention: The truss robot 4 includes a trolley 4B, a carriage 4C, and a lifting device 4D. The trolley 4B includes a traveling device 4B1.

The carriage 4C runs horizontally on the trolley 4B.
[0013] As a further solution of the present invention: The truss robot 4 includes a slewing device 4E. The lifting device 4D includes a multi-stage lifting device 4D1. The jaw 4A is installed on the slewing device 4E, and the slewing device 4E is installed at the bottom of the lifting device 4D when it is at the lowest position.
[0014] As a further solution of the present invention: The empty hanger 5A can carry the spreader device 5B and enter or leave the narrow conveyor 3 at the starting section 3A or the ending section 3B.
[0015] As a further solution of the present invention: the paint production line includes an operation chamber 8 with a cover on the top, the operation chamber 8 includes a cover 8A located outside the top and brackets 8B located on both sides inside the operation chamber 8, and the painting operation of the operation chamber 8 is carried out in a state where both ends of the hanging bracket 5A are placed on the brackets 8B.
[0016] As a further solution of the present invention: the workpiece 1 includes a bogie 1A in a railway vehicle and an H-shaped frame in construction machinery.
[0017] In summary, compared with the prior art, the main features of the present invention are: the truss robot is used to realize the operation of the workpiece between all or part of the functional chambers. Since the truss robot can operate in three-dimensional space, as long as it is within the coverage range of the truss robot, each functional chamber can be flexibly arranged according to the process requirements, and the process route can also be flexibly set according to the production needs.
[0018] The main advantages of the present invention are: the shortest path selected by the computer system is used, and the truss robot is adopted to complete the conveying of the workpiece between the functional chambers; therefore, the structure of the production line is simple, the equipment is easy to arrange, the floor area is small, and the cost is low.
