In industries including electronics manufacturing, new energy and automotive manufacturing, RTV silicone (Room Temperature Vulcanizing silicone) is widely used in component fixing, waterproof sealing, thermal conductive filling and other processes due to its excellent adhesion, sealing, insulation and high- and low- temperature resistance. With more than 20 years of deep cultivation in the fluid dispensing field, Second Intelligent has launched a benchtop RTV dispensing system. With core advantages of high precision, high stability and strong compatibility, it has become the preferred equipment for dispensing RTV silicone and thermal gel, helping enterprises achieve automated and efficient production.
(1) Industry Pain Points: Core Challenges in RTV Dispensing Processes
RTV silicone generally has a viscosity of 60,000–100,000 cps, and some processes require matching thermal gel (such as models with a high thermal conductivity of 4.5 W/m·K). Traditional dispensing equipment often suffers from the following drawbacks:
● Insufficient precision: Uneven dispensing of high-viscosity adhesives and large deviations in dispensing positions lead to poor sealing and bonding failure;
● Poor compatibility: Inability to adapt to both 2600 ml bulk RTV silicone cartridges and 150 cc syringes, resulting in cumbersome adhesive replacement;
● Low automation: Reliance on manual positioning and programming, low production efficiency and susceptibility to human errors;
● Lack of stability: Prone to adhesive leakage and interruption during long-term operation, high equipment failure rate and increased production costs.
Second Intelligent RTV dispensing equipment directly addresses these industry pain points, uses advanced technologies to solve high viscosity fluid dispensing challenges, and provides enterprises with one-stop solutions.
(2) Core Advantages of Second Intelligent RTV Dispensing Equipment
1. High-Precision Motion Control
The Second SEC-E480 series RTV dispensing equipment adopts servo motors coupled with ground ball screws for driving, paired with an integrally cast aluminum alloy frame. The X/Y-axis transmission components are directly fixed to the casting, minimizing component errors and ensuring stable and reliable operation.
● Effective stroke: X/Y = 480 mm, Z = 100 mm; dispensing area up to X350 * Y350 mm (SEC-E480S-L) and X400 * Y400 mm (SEC-E480SV);
● Repeat positioning accuracy: ±0.015 mm; three-axis linkage of XYZ supports continuous interpolation of dots, lines, surfaces, arcs and irregular curves to meet complex trajectory dispensing requirements;
● Operating speed: Maximum 500 mm/s for X/Y axes and 200 mm/s for Z axis, balancing precision and efficiency for mass production.
2. Dual Mode Adhesive Supply System for Full-Scenario RTV / Thermal Gel Applications
Targeting mainstream packaging formats including 2600 ml RTV silicone cartridges and 150 cc thermal gel syringes, the equipment is equipped with a dual adhesive supply system supporting one-key switching. It accommodates adhesives with viscosity ranging from 1,000 to 200,000 cps, covering various fluids such as RTV silicone, thermal gel, epoxy adhesive and UV adhesive dispensing machine.
● 2600 ml pressure tank supply: Pneumatically driven (0.2–0.8 MPa), pressure-resistant seamless steel tank body with adhesive shortage buzzer alarm, suitable for large-batch continuous production;
● 150 cc syringe pressing assembly: Pneumatically driven with stainless steel flow path, suitable for small-to-medium batch and multi-category production with convenient adhesive replacement;
●Dispensing valve configuration: Standard medium back-pull valve + screw valve, with adjustable back-pull shut-off stroke to eliminate stringing and leakage of high-viscosity adhesives.
3. Intelligent CCD Visual Positioning for Full Automation
The equipment integrates a 1.3-megapixel CCD vision system (Hikvision camera) with Mark point positioning, laser height measurement and automatic deviation correction, completely eliminating manual dependence.
●Visual positioning: Single Mark point recognition time of 200 ms, supporting single / dual Mark point positioning, automatic alarm when errors exceed thresholds, and real-time dispensing path correction within tolerance range;
●Laser height measurement: Detection range from 30±4 mm to 250±150 mm, repeat accuracy of 4 μm–100 μm, automatic compensation for product height deviations to ensure consistent dispensing;
●Multi-function integration: Compatible with coaxial light, ring light, strip light and other light sources; supports code scanning and appearance defect inspection; can connect to MES systems and upload process data for production traceability.
4. Modular Design for Flexible Adaptation to Diverse Production Scenarios
Second RTV dispensing equipment features a modular architecture supporting customized upgrades to meet different production scenarios.
1)SEC-E480S-L adopts a 6-axis design (including conveyor line), matched with a three-stage chain conveyor (feeding / working / discharging) to support automated assembly line production;
2)SEC-E480SV adopts a 5-axis design (including ZR rotary axis), supporting 360° rotation and 90° swing for dispensing on irregular parts and multi-angle applications.
●Compact footprint: Equipment dimensions (L×W×H) 1200/1500 mm × 1000 mm × 1600 mm; benchtop installation requires no complex site modification, suitable for small and medium sized workshops;
●Easy maintenance: Core components adopt branded products such as Inovance servo motors and Airtac guide rails, with a simplified structure to reduce later maintenance costs.
