Core Components
Micro-Precision Dispensing System
Composed of an imported high-precision gear pump (US MAC or VERMES) and replaceable micro-nozzles (0.1-0.5mm diameter). The gear pump adopts frequency conversion speed regulation and DST (Dynamic Shockwave Technology) to ensure precise control of glue output (adjustable within 0.01-5g/s) and repeatable dispensing accuracy of ±1%. The micro-nozzles are available in various types (point, line, micro-spray) to meet different electronic bonding needs-point dispensing for chip fixing, line dispensing for wire harness bonding, and micro-spray for PCB board protection.
Multi-Zone PID Intelligent Temperature Control System
dopts multi-zone independent PID temperature control technology, with a temperature control range of 0-230℃ (adjustable in 1℃ increments) and control precision of ±0.5-1℃. The melting tank, glue delivery pipeline, and dispensing head are independently heated to ensure uniform temperature distribution and stable glue fluidity, avoiding glue carbonization or poor fluidity caused by uneven heating. Equipped with high and low temperature protection, overheating alarm, and automatic temperature compensation functions to prevent equipment damage and ensure the hot melt glue maintains optimal viscosity-critical for bonding heat-sensitive electronic components
Anti-Static & Dust-Free Design
The entire machine adopts an anti-static design (surface resistance ≤10^8Ω) to prevent static electricity from damaging electronic components (such as chips, capacitors, and PCBs). The dispensing head and glue tank are equipped with anti-static coatings, and the machine is compatible with cleanroom environments (Class 1000 cleanroom compatible) to avoid dust contamination during the bonding process-essential for high-precision electronic production.
Intelligent Control & Positioning System
Equipped with a 4.3-7 inch LCD touchscreen (supporting English and multi-language) for intuitive parameter setting-glue temperature, dispensing time, glue output, dispensing speed, and path can be adjusted with one click. The system supports parameter storage (up to 999 groups of templates) for quick switching between different electronic components, reducing changeover time. It also integrates a high-precision motion platform (X/Y/Z axis) with repeat positioning accuracy of ±0.01-0.02mm (screw drive) or ±0.02-0.04mm (synchronous belt), ensuring precise alignment with tiny electronic parts. Optional CCD visual positioning system is available for automatic product recognition and trajectory compensation, further improving dispensing accuracy.
Core Advantages
1. Micro-Precision Dispensing & Consistent Bonding Quality
Adopts imported high-precision gear pumps, micro-nozzles, and multi-zone PID temperature control, achieving micron-level dispensing precision (±0.01-0.05mm) and repeatable glue output accuracy of ±1%. The precise glue cut-off design avoids wire drawing and glue leakage, ensuring uniform glue application on tiny electronic components (chips, PCBs, wires). The bonded components have strong adhesion, good consistency, and a low defective rate (≤0.1%), significantly improving product quality and reducing rework costs.
2. Anti-Static & Dust-Free Design, Protects Electronic Components
The entire machine adopts an anti-static design (surface resistance ≤10^8Ω) to prevent static electricity from damaging sensitive electronic components (such as chips, capacitors, and PCBs)-a critical advantage for electronic production. The dust-free design (Class 1000 cleanroom compatible) avoids dust contamination during the bonding process, ensuring the reliability and service life of electronic products. This design reduces component damage rate by 80% compared to general-purpose dispensers.
3. Low-Temperature Compatibility, No Damage to Heat-Sensitive Components
Equipped with a low-temperature heating system (120-180℃ for consumer electronics models) and multi-zone temperature control, ensuring the hot melt glue melts evenly without overheating-avoiding damage to heat-sensitive electronic components (e.g., smartphone displays, camera modules, chips). The adjustable temperature range adapts to different types of low-temperature hot melt adhesives, meeting the bonding needs of various electronic components.
4. High Efficiency & Labor Cost Savings
Compared to manual bonding, the machine improves work efficiency by 4-6 times, with a dispensing speed of 50-300 mm/s and a production capacity of 1000-3000 pieces per hour (depending on component size)[4][6]. One operator can complete the entire process (component positioning + machine triggering), replacing 2-3 manual workers, reducing labor costs by 60-70%. The fast preheating time (10-20 minutes) and parameter template storage function reduce changeover time, ensuring uninterrupted production.
