Problems solved by technology

However, due to the limitation of the overall technical level of my country's manufacturing industry, no substantive breakthroughs have been made to the problem of low precision of serial robots. The control of serial spraying robots is relatively complicated. In addition, related foreign patents still apply to its application in my country. Various restrictions have been carried out, so inventing a new type of spraying robot is an urgent task for my country's automobile industry

Embodiment 1

[0032] Such as figure 1 As shown, the combined spraying robot that can complete the automatic spraying operation for the whole vehicle of the present invention includes a gantry frame 17 and four spraying operation module units. The spraying operation modules are respectively the first spraying operation module ①, the second spraying operation module ②, the third spraying operation module ③, and the fourth spraying operation module ④, all of which are parallel robots. Among them, the first spraying operation module ① and the fourth spraying operation module ④ have the same structure, and they are respectively symmetrically installed on the two columns of the gantry frame 17; the second spraying operation module ② and the third spraying operation module ③ structure Also exactly the same, it is respectively fixed on the third spraying operation module motion slide block 18 and the second spraying operation module motion slide block 110, and the upper beam guide rail 19 of the mo...

Embodiment 2

[0039] Such as Figure 4 As shown, according to the present invention, in Embodiment 2, another planar three-degree-of-freedom parallel mechanism is used to replace the planar five-bar parallel mechanism in Embodiment 1 as the second spraying operation module ② and the third spraying module in the combined spraying robot. Operation module③. It includes a third moving frame 41, a third moving platform 37, a first branch chain, a second branch chain, and a third branch chain. The first branch chain and the second branch chain have the same structure, and are respectively used to connect the third moving platform 37 and the third moving frame 41, in order to determine the position of the third moving platform 37, the third branch The chain is used to connect the moving frame 41 and the third moving platform 37 to change the posture of the third moving platform 37 . Described first branch chain comprises slide block I42, first connecting rod 43, motion pair group IV; Described s...

Abstract

The invention relates to a hybrid connected combined vehicle spraying robot based on a 3-DOF (Degrees Of Freedom) and 4-DOF parallel mechanism, comprising a gantry stand and four spraying operation module units, wherein the gantry stand can realize horizontal motion on a horizontal guide rail, and the pose of an atomizer nozzle of each spraying operation module unit can be controlled by combining the horizontal motion of the gantry stand and motion of the spraying operation module units, thereby finishing whole vehicle spraying operation of a vehicle to be sprayed. The hybrid connected combined vehicle spraying robot has the advantages of symmetric structure, good flexibility, high accuracy and rigidity, easy manufacture, convenient control, easy modularization realization and high flexibility degree, can increase and decrease an amount of spraying modules according to the needs and carrying spraying operation on different whole vehicles.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a modular combined spraying robot that can be applied to the field of complete automobile spraying production. Background technique [0002] With the rapid development of the modern automobile industry, the continuous adjustment of car models and car body design, domestic car production is developing in the direction of large-scale, high-quality and low-cost, and car body spraying is one of the most important production processes in car manufacturing , it can not only improve the corrosion resistance of automobile products and prolong the service life of automobiles, it also most directly reflects the quality of the color, gloss and brightness of the outer surface of the automobile, and is the most intuitive evaluation of the quality of automobiles, so it is the most intuitive evaluation of automobile quality. The competitiveness of the automobile market has the most direc...
