1. Introduction
With the accelerated penetration of industrial automation and intelligent manufacturing, the application of sealing robots in modern production lines is increasingly widespread. Different from manual sealing operations, sealing robots require sealing materials to have excellent process adaptability, stable rheological properties, low pollution and easy maintenance characteristics. Traditional sealing glues often have problems such as high volatility, serious nozzle residue, difficult cleaning, large amount of glue waste and environmental hazards in automated operation, which lead to nozzle blockage, uneven glue output, unstable sealing quality and increased production downtime of sealing robots, seriously restricting the improvement of production efficiency and product quality.
Clean glue for sealing robot is a new type of environmental friendly functional adhesive developed for the above pain points. It takes clean operation, precision adaptation, low residue and easy maintenance as the core design goals, and is specially optimized for the dispensing system, motion control and process parameters of sealing robots. In the context of global emphasis on green manufacturing, clean production and product quality upgrading, clean glue has gradually replaced traditional sealing materials and become the preferred matching material for high-end sealing robots. This paper focuses on the technical characteristics, automation matching, industrial application and development trend of clean glue for sealing robots, aiming to provide theoretical reference and practical guidance for the selection, application and process optimization of sealing materials in automated production lines.
2. Overview of Clean Glue For Sealing Robot
2.1 Definition and Core Connotation
Clean glue for sealing robot refers to a kind of sealing adhesive material with low volatile organic compounds (VOCs), low residue, no dripping, no wire drawing, easy cleaning, stable fluidity and precise curing performance, which is specially developed for the automatic dispensing, coating and sealing process of industrial sealing robots. Its core connotation is reflected in three aspects: first, process cleanliness, that is, no excess overflow, no nozzle residue, no environmental pollution during automatic operation; second, equipment friendliness, that is, no corrosion to the robot's dispensing valve, pipeline and nozzle, easy to clean and maintain, reducing equipment failure rate; third, product reliability, that is, forming a uniform, dense and stable sealing layer after curing, with excellent waterproof, dustproof, shockproof and aging resistance.
2.2 Difference Between Clean Glue and Traditional Sealing Glue
Compared with traditional silicone sealant, polysulfide glue, polyurethane glue and other sealing materials, clean glue for sealing robot has obvious advantages in process performance and environmental protection. Traditional sealing glue is prone to wire drawing, dripping, overflow and nozzle blockage in the process of robot automatic dispensing, which requires frequent manual cleaning and maintenance, resulting in low production efficiency and high labor costs. At the same time, traditional glue often contains a large number of solvents and volatile components, which not only pollute the production environment, but also affect the health of operators. Clean glue adopts solvent-free or low-solvent formula, with optimized rheological properties, which can realize stable glue output, precise dosing and clean cutting under the drive of sealing robot, completely solving the pain points of traditional glue in automated operation.
3. Technical Characteristics of Clean Glue For Sealing Robot
