For painting machine construction, we have numorous control options to make it completely fulfill onsite spray requirements. Either PLC or motion control card is widely used with its specific advantages. In RPG group, we have both being used for different painting machines electric programming. To understand more about the two, we have following article for quick guides. The fundamental difference between motion control card and PLC lies in their positioning: motion control card specializes in high-precision, complex motion control, whereas PLC focus primarily on logical sequence control. They differ significantly in terms of hardware architecture, programming methods, and performance specifications, making them suitable for different automation scenarios. Differences in Core Functional Positioning Motion Control Card: Specifically designed for motion control, featuring robust multi-axis coordination capabilities. It supports precise management of…

Conductive paint is a functional coating material composed of a base resin, conductive fillers (such as metal particles or graphite), solvents, and additives. Conductive coatings are generally categorized into two types: anti-static paint and truly conductive paint. The former serves a dual function - providing both corrosion protection and anti-static properties and is typically applied to equipment such as storage tanks. The latter possesses a higher electrical conductivity (surface resistivity ≤ 0.025–0.25 Ω/cm²) and is utilized for electromagnetic shielding and the corrosion protection of underground power grids. Conductive paints are formulated as single-component coatings using metal fillers such as silver, copper, or nickel, and can be spray-applied to the surfaces of metal or plastic substrates. Representative products—such as TF-801 (silver-copper based) and TF-606 (nickel-based)—are well-suited for the processing of plastics…

UV intelligent power supplies exhibit significant generational differences compared to traditional power supplies in industrial applications. These differences are primarily manifested across four key dimensions—energy efficiency, control precision, response speed, and level of intelligence—in all of which they comprehensively outperform traditional transformer-based power supplies. Consequently, they are particularly well-suited for scenarios with stringent requirements for process stability and cost control, such as automated spray coating lines. Core Performance Comparison ITEM Transformer + Capacitor UV Intelligent Power(High-Frequency Variable Frequency + Intelligent Control) ‌Energy conversion efficiency‌ 75%–80% ‌92%–96%‌ ‌Power Regulation Method‌ Fixed Three-Speed（Ex. 50% /75% /100%） ‌10%–100% Stepless Dimming ‌Startup Response Time‌ 1–3s ‌≤8ms‌ ‌Standby Power Consumption‌ Minimum 50% of rated power ‌Can be reduced to 10%‌ ‌Impact on Lamp Lifespan Frequent high-voltage surges lead to a shortened service life.

Ensuring consistent coating thickness in automated spray painting hinges on the synergistic management of equipment automation, closed-loop control of process parameters, and real-time monitoring. Particularly in high-volume production environments, stability and repeatability constitute the core objectives. Precise Control of Automated Spraying Systems Robot Path Programming: Through teach-in programming or offline simulation, the system ensures highly repeatable spray gun trajectories, guaranteeing complete coverage of the target area without omissions or excessive overlap—a capability particularly well-suited for workpieces with complex curved surfaces. Constant Spraying Distance: Utilizing laser rangefinders or vision-guided systems, the robotic arm's posture is automatically adjusted to consistently maintain a distance of 15–25 cm between the spray gun and the workpiece surface. Uniform Movement Control: The robot moves at a constant speed of 30–60 cm/s, thereby eliminating the speed fluctuations…

We have developped an automatic loading machine for vacuum metallization painting line system considerring its great improvement to reduce labor works. When it's well programmed and everything well tested for live production, suddenly some day we found the automatic loader can not put objects properly to chain spindle. After inspection on each unit carefully we finally found its due to the chain pitch elongated during operation. Technically speaking, the painting line system is a high precision setup which should be always accurate in mechanical structure. Among all the components, conveyor chain is the most crutial part as it will carry all spindles and products to pass through various treatment stations. Elongated chains in painting lines will directly trigger a series of cascading failures in terms of machinery, processes, and safety.…
