A robot lifting platform for surface spraying of large equipment

Abstract

The invention relates to a robot lifting platform for spraying on the surface of large-scale equipment, which includes a drive mechanism, a transmission mechanism and a telescopic tube assembly that are connected to each other and form an integrated structure. The barrel assembly is used to adjust the degree of freedom of lifting. It can be seen from the above technical solution that the present invention has compact structure, precise and stable movement, large lifting distance, and stable movement by adjusting the reduction ratio.

Description

technical field [0001] The present invention relates to the technical field of robots, in particular to a robot lifting head for spraying on the surface of large equipment. Background technique [0002] Compared with traditional manual spraying, machine spraying has the advantages of high spraying quality, stable and controllable nozzle movement speed, accurate and stable paint flow, effective control of uniform coating thickness, and high production efficiency. The control program responds to the surface shape changes of different parts without changing the production line, which can meet the flexible manufacturing needs of modern factories; the spraying robot can also control the effective range of paint spraying by precisely controlling the angle and distance between the spray gun and the workpiece, improving the spraying efficiency. and pass rate, etc., laying a technical foundation for the production of high-quality aircraft or other large equipment surfaces. However, ...

Problems solved by technology

However, the common problems at present are: due to the large size of large equipment, manual spraying is time-consuming and labor-intensive, and the requirements for workers' experience and operation are also extremely high; Poor, the stability of the system is not very good, the transmission accuracy is low, and the spraying quality is not ideal

For example: the invention patent of a two-stage automatic lifting spraying device (CN110185241A), which is only suitable for some indoor decoration occasions, and the two-stage lifting function cannot meet the spraying requirements of some large-scale equipment; the utility model of the spraying robot lifting mechanism and lifting mobile device The patent (CN208686029U) uses a link mechanism for lifting, which cannot meet the needs of large-span lifting, and the distance and speed of the lifting are difficult to control precisely; a utility model patent (CN205659841U) for a liftable spraying device uses a chain drive for lifting, and a chain drive The mechanism is easy to wear and stretch, and the transmission stability is poor. Additional dynamic load, vibration, impact and noise will be generated during operation, which is not conducive to high-quality spraying operations
