Automatic Spray Specimen Preparation Workstation LASSP-A10

Labtron’s modern automatic spray specimen preparation workstation LASSP-A10 include fully enclosed spray chambers equipped with water-curtain overspray capture systems and regenerative thermal oxidizers or scrubbers for VOC removal. Overspray is collected in liquid tanks and treated, while vapors are directed through multi-stage filtration to achieve regulatory-compliant emissions. Solvent recovery mechanisms significantly reduce chemical waste, and separate aqueous and solvent waste streams simplify disposal. Automated monitoring logs VOC levels and filter lifespans to maintain continuous compliance. These systems greatly reduce operator exposure to hazardous fumes and cut environmental impact through efficient resource use.

Labtron’s High-end automatic spray specimen preparation workstation LASSP-A10 integrate collaborative six-axis robot arms—such as Fanuc or ABB—fitted with vacuum suction feeders and pneumatic grippers. They incorporate 2D/3D vision systems to detect panel location and orientation, automatically adjusting the handling path to ensure precise spray coverage. Robots traverse a programmed motion sequence that includes loading, spraying, curing, and unloading, eliminating manual transfer. This closed-loop operation enhances throughput and reduces contamination risk. Centralized control via PLCs and remote monitoring interfaces further streamline process integration and quality assurance.

Labtron’s automatic spray specimen preparation workstation LASSP-A10 rely on advanced spray applicators—such as Graco ProMix and Ransburg Evolver 560—that offer real-time control over fluid pressure, flow rate, nozzle type, and pattern. Colour-change valves and proportioning systems support rapid line switching with minimal purge waste. Built-in sensors track spray thickness while robot dynamics ensure consistent deposition. Feedback loops regulate gun voltage and pressure to maintain target atomization. The entire process is programmable, allowing preset recipes for different coatings and substrates—ensuring repeatable high-quality finishes with optimized material usage.

Curing is handled within the spray enclosure via inline ovens (typically 1–3?kW) capable of temperatures up to 150?°C, allowing freshly sprayed panels to enter drying immediately. Conveyor belts or robotic shuttles transfer panels seamlessly from spray to cure zones without exposure. Bake profiles—temperature, duration, humidity—are programmable per panel batch and tightly controlled. Enclosure thermal insulation reduces heat loss and energy consumption, while inert-air purges mitigate fire risk. This compact, self-contained workflow eliminates external ovens, reduces footprint, and ensures consistent cure conditions

Labtron’s automatic spray specimen preparation workstation LASSP-A10 fully enclosed chambers maintain negative pressure with controlled airflow and VOC-level sensors Exhaust streams pass through multi-stage filtration—bag filters, cyclones, or scrubbers—to capture particulates and vapours. Fire safety is addressed by inert-air purge before heating stages. Emergency stops, overload-release systems, and interlocks shut down the line on fault detection. Temperature and solvent sensors prevent unsafe conditions during cure. Automated diagnostics continuously monitor filters, pressures, and motors. These measures ensure EPA or local environmental compliance and protect operators from fumes and fire hazards.

Labtron’s automatic spray specimen preparation workstation employs precision-controlled pressure regulators linked to high-resolution sensors, ensuring that liquid and atomizing air stay within set tolerances. Nozzles—often servo-driven—operate between defined pressure ranges (e.g., up to 0.7?MPa) to control droplet size and coverage, and spray speed is adjustable (e.g., 0–500?mm/s) to tune film thickness accordingly. Real-time feedback adjusts flow automatically to compensate for viscosity or solvent-level changes. Operators validate performance using reference test panels and record calibration data in the system’s log. Uniform flow ensures reproducible coatings and analytic accuracy. Regular nozzle checks prevent drift from specifying errors. Together, these controls maintain uniform specimen preparation.

Labtron supplies advanced models of automatic spray specimen preparation workstation. After a coating cycle, the workstation initiates a "solvent flush–air purge–rinse–air purge" sequence to clean the application gun. Solvent is pumped from the 5?L reservoir to flush internal channels, followed by compressed-air blast to clear residues. Often a brushing ring or agitation enhances cleaning efficiency. Waste solvent returns to a holding tank for disposal or recycling. Enclosed ventilation captures any vapor, directing it to scrubbers or filters. Every cleaning cycle is digitally logged, with solvent level monitoring triggering refill alerts. This comprehensive protocol mitigates nozzle clogging, ensures spray quality, and supports hygienic operations and operator safety.

The exhaust system integrates wet or spray-tower scrubbers to capture solvent mists and vapors efficiently. Counter current spray schemes direct solvent or water sprays across ventilation flow, capturing droplets in scrubbing towers and using mist eliminators to separate cleaned air. Packed-bed or Venturi-style scrubbers may be employed to enhance removal of fine droplets and VOCs. Periodic automatic purges maintain scrubber efficiency, while sensors track liquid levels, trigger replenishment, and monitor air quality. This design achieves regulatory compliance, keeps lab air clean, and reduces environmental impact.

Labtron supplies advanced models of automatic spray specimen preparation workstation. Immediately after spray application, specimens are transferred into an integrated drying or curing zone—often a heated chamber or infrared dryer capable of reaching ~150?°C, powered around 2?kW. Temperature and duration are pre-programmed and monitored via sensors for repeatability. Automated transfer mechanisms, such as robotic arms or conveyors, minimize manual handling and cross-contamination risks. Every drying cycle, including parameters and timestamps, is logged for traceability. Once cured, specimens are ready for analysis or packaging without further intervention, streamlining workflow efficiency and ensuring consistent preparation standards.

Maintenance follows a scheduled rhythm: weekly tasks include reservoir-level checks, lint trap or filter clearance, and visual inspection of chambers; monthly tasks cover nozzle and sensor calibration, solvent-filter replacement, and scrubber liquid refresh. Quarterly checks involve heating-element diagnostics, fan/filter servicing, and ventilation integrity. Annual preventive maintenance includes full calibration, software updates, and system diagnostics, often performed by certified engineers. All tasks are logged digitally, maintaining audit-ready records. This routine upkeep ensures uptime, consistent output quality, compliance, and safety across operations.
