Description

Technical Field

[0001] This utility model belongs to the field of simulated plant processing technology, and in particular relates to a robotic arm device for uniformly spraying water-based solutions. Background Technology

[0002] In the manufacturing process of simulated plant leaves, spraying water-based solutions is mainly used to enhance the product's appearance, texture, functionality, and durability. Its main functions and specific applications include:

[0003] 1) Enhance the realism of the appearance: cover up color differences after injection molding or trimming (such as traces left by the sprue), achieve natural gradient effects (such as yellowing leaf tips and varying shades of leaf veins), and simulate texture (matte finish, enhanced texture).

[0004] 2) Functional optimization: as a protective coating such as UV protection (water-based UV protective liquid can delay fading and embrittlement caused by sunlight when used outdoors), waterproof and stain-resistant (forms a hydrophobic layer, reduces dust adhesion, and is easy to clean), and improves durability (reduces oxidation aging, extends service life, and is suitable for high temperature and high humidity environments).

[0005] 3) Environmental protection and safety: Water-based solutions do not contain organic solvents (VOCs), making them suitable for scenarios with high safety requirements, such as home decoration. Compared to oil-based paints, water-based coatings are easier to clean and reduce pollution.

[0006] 4) Achieving special effects (such as biomimetic details and gloss control) and compensating for process defects (covering up flaws and filling tiny pores to create a uniform surface).

[0007] Currently, water-based solutions can be sprayed onto plant leaves using robotic arms in conjunction with nozzles. However, due to the unevenness of plant leaf surfaces or the different angles at which spraying points are required, most existing nozzle structures are either fixed or oscillating.

[0008] Fixed nozzles have a fixed spray hole direction. If the spraying angle is adjusted by relying solely on the movement trajectory of a robotic arm, it is suitable for simple flat surface spraying. However, the curved surface of plant leaves will result in uneven coating thickness, affecting product quality.

[0009] The oscillating nozzle swings back and forth during use, but the swing angle is limited, so it is still not suitable for uniform spraying on curved surfaces, resulting in poor uniformity. Summary of the Invention

[0010] The purpose of this invention is to provide a robotic arm device for uniformly spraying water-based solutions. By designing a novel omnidirectional spraying mechanism in conjunction with the robotic arm, the angle of the nozzle valve can be controlled by an electric push rod and a connecting rod, and the orientation of the nozzle valve can be adjusted by a motor. Together with the robotic arm, it can achieve spraying without dead angles, is suitable for spraying complex simulated plant leaves, and is suitable for use on curved surfaces. It greatly improves the uniformity of spraying, while also increasing spraying efficiency and ensuring product quality.
