Second Intelligent Dispensing Systems: Core Technological Breakthroughs Redefine Precision Fluid Control

 In modern electronics manufacturing, automotive electronics, medical devices, and new energy equipment, high-precision dispensing technology has become a critical factor impacting product reliability and production efficiency. As a high-tech enterprise specializing in fluid control automation, Shenzhen Second Intelligent Equipment Co., Ltd. has achieved systematic breakthroughs in core dispensing technologies through nearly two decades of specialization. Its products now set international benchmarks in positioning accuracy, dispensing consistency, and complex-path adaptability.

Core Challenges in Dispensing Technology

Precision dispensing is far more than simple fluid extrusion—it's a complex system engineering feat involving fluid dynamics control, precision mechanical transmission, and real-time dynamic compensation. At millimeter-scale dispensing paths, variables like adhesive viscosity fluctuations, temperature variations, substrate deformation, and motion control errors significantly impact results. Traditional dispensers often exhibit broken glue lines, uneven deposition, and positional deviations during 3D-path operations, directly compromising waterproof sealing, electrical conductivity, and structural integrity. Second Intelligent addresses these pain points with a comprehensive technological solution spanning fundamental principles to control systems.

Fundamental Working Principles: A Scientific Architecture of Precision Control

Second’s dispensing systems adopt a triple-technology architecture integrating “pneumatic drive + servo control + machine vision” with four core operational modules:

Fluid Delivery System
Adhesives are supplied via pressure pots or cartridge barrels, propelled through precision pressure regulators to dispensing valves.

Core Actuation Mechanism
Dispensing valves (including needle valves, screw valves, and piezoelectric jet valves) enable precise start/stop control via electrical signals.

Motion Control System
Three-axis platforms or six-axis robots guide dispensing heads along predefined trajectories with micron-level reproducibility.

Quality Assurance System
CCD vision systems monitor deposition positions in real-time, while laser height sensors dynamically compensate Z-axis variations.

Critically, Second enhances traditional open-loop systems with real-time feedback mechanisms—high-resolution sensors monitor glue pressure, flow rate, and positional data to establish closed-loop control, ensuring precision at the principle level.

Four Core Technological Breakthroughs: Second’s Proprietary Advantages

Second has achieved revolutionary advancements in four key areas that form competitive barriers:

1.Rotary Nozzle Dispensing Technology
As China’s sole master of this technology, Second enables active rotational controlof nozzles during dispensing. This creates optimized fluid interfaces at needle tips, producing triangular glue-line profiles. Essential for EMI shielding in communication devices and irregular-surface coating, it eliminates adhesive accumulation at corners and enables uniform 3D surface coverage.

2.High-Speed Vision Positioning
Integrating German industrial CCDs with multispectral LED lighting achieves ±0.015mm positioning accuracy. Proprietary feature-matching algorithms automatically correct dispensing paths despite ±5° angular deviations or 2mm placement errors, increasing production line yield by 15%+ by eliminating manual-loading inaccuracies.

3.Sub-Millisecond Valve Response
Second's proprietary piezoelectric valves operate 30% faster than industry standards with 0.8ms response times. Combined with unique suck-back technology, this creates instant negative pressure for "knife-cut separation" at needle tips—completely eliminating stringing and dripping. Particularly vital for microelectronics packaging, it ensures ±0.01ml accuracy on 0.2mm solder pads.

4.Adaptive Height Compensation
For curved substrates or warped PCBs, integrated laser sensors enable dynamic Z-axis adjustments. Pre-dispensing 3D scans create height topology maps, allowing real-time needle-height adjustments to maintain 0.5-1mm optimal working distances—solving challenges in automotive electronics sealing and LED lens encapsulation.

Precision Meets Intelligent Control

Second's excellence stems not just from hardware innovations but deeply optimized control systems:

Motion Control
A PC + dedicated motion card architecture with Panasonic servos and ball screws achieves 500mm/s linear speeds while supporting point-to-point, linear, circular, and spline interpolations (±0.025mm repeatability).

· 

· 

Glue Volume Control
Servo-driven piston metering delivers 0.001ml resolution, with automatic parameter optimization via viscosity-pressure-temperature matrices.

Pre-Delivery: 15-day continuous operation tests + approval by senior engineers (5+ years' experience)

Deployment: Onsite technician training + process optimization for specific products

Operations: 24/7 response (3-hour remote troubleshooting, 24-hour onsite support), enabling 98%+ OEE at clients like Huawei and Lenovo

Conclusion

Through fundamental innovations and sustained technological breakthroughs, Second Intelligent has established new global standards in precision dispensing. Its rotary nozzle technology breaks foreign monopolies, while vision systems redefine accuracy limits. These integrated advancements transform dispensing from simple fluid allocation into a cornerstone of smart manufacturing. With 5G, new energy, and wearable technologies advancing, Second's R&D in micro-dispensing and nano-silver sintering will continue driving Chinese advanced manufacturing toward unprecedented precision and reliability.
