TECHNICAL FIELD
[0001] The present application relates to the technical field of paint spraying robots, in particular to a reciprocating multi-nozzle high-efficiency paint spraying robot for wooden furniture. BACKGROUND
[0002] Wooden furniture paint spraying is a key process in furniture manufacturing, directly affecting the appearance quality, durability and market value of the product. Traditional paint spraying methods mainly rely on manual operation or simple automatic equipment, which has problems such as low efficiency, poor consistency, and serious environmental pollution. With the improvement of intelligent manufacturing and environmental protection requirements, paint spraying robot technology has gradually been applied in this field, aiming to achieve efficient, uniform and environmentally friendly paint spraying operations.
[0003] Although the existing paint spraying robot technology has partially solved the automation problem, there are still some technical defects in the application scene of wooden furniture: First, the existing paint spraying equipment mostly adopts a single nozzle structure, and the paint spraying range is limited. In order to cover a large area of furniture surface, multiple movements or repeated spraying are required, which not only reduces the efficiency, but also easily causes uneven paint film thickness due to overlapping spraying; Second, the existing paint spraying equipment often ignores the real-time treatment of paint mist, or uses a fixed mist suction device (such as a workshop top exhaust system). However, it takes a long time for the paint mist to be sucked after it disperses, resulting in some paint mist spreading into the environment. An independent power system (such as an additional motor) drives the mist suction device, increasing energy consumption and equipment complexity. Moreover, the fixedly installed mist suction system cannot move with the paint spraying unit, resulting in a decay of the suction effect with distance; Therefore, the present application proposes a reciprocating multi-nozzle high-efficiency paint spraying robot for wooden furniture.
