Product Features
Integrated Built-in Check Valve, No Extra Assembly Needed: One-piece integrated design with internal embedded one-way check valve, eliminating tedious external valve assembly and pipeline layout. Simplifies pneumatic system structure, reduces equipment failure points and lowers overall installation cost.
Professional Anti-leakage for Porous PCB Workpieces: Real-time automatic sealing response for PCB via holes and porous surfaces. The internal check valve instantly cuts off local air leakage channels, effectively solving suction failure and workpiece dropping caused by vacuum pressure loss on perforated circuit boards.
Anti-static Rubber Material for Electronic Safety: Adopts professional ESD anti-static rubber raw material, which can conduct static electricity rapidly during grabbing operation. It prevents static breakdown and circuit damage to sensitive PCBs and electronic chips, meeting electronic workshop anti-static production standards.
Mini Compact Body for Precision Automation: Ultra-small integrated size adapts to compact end fixtures of electronic manipulators and automatic testing machines, suitable for high-density multi-nozzle combined grabbing without mutual interference between adjacent suction nozzles.
Traceless Soft Contact Protection: Soft elastic suction lip fits closely with flat and thin PCB surfaces uniformly, dispersing suction pressure evenly. No indentation, scratch or surface damage on fragile thin circuit boards and test tubes during high-speed cyclic handling.
Fast Vacuum Response & Stable Operation: Optimized internal airflow channel improves vacuum suction and deflation speed, matching high-frequency automatic handling and testing cycle rhythm of electronic production lines, ensuring consistent and reliable suction performance for long-term continuous operation.
Product Advantages
First, Perfect solution for porous PCB air leakage problem. Unique built-in check valve targets the biggest pain point of PCB handling, maintaining stable system vacuum even when partial suction areas cover via holes, greatly reducing workpiece falling rate. Second, Integrated structure saves system cost. All-in-one design removes the need for separate external check valves and connecting pipelines, simplifying equipment structure and cutting spare parts procurement and maintenance costs. Third, Built-in anti-static function protects electronic workpieces. Professional static-dissipating rubber avoids static damage to precision circuit boards, lowering product defective rate in electronic automated processing. Fourth, Dual-purpose for PCB and test tube handling. Compatible with flat porous circuit boards and cylindrical test tubes, realizing one suction nozzle for two common electronic handling scenarios to enrich equipment application range. Fifth, Plug-and-play easy replacement: Standard universal pneumatic interface matches mainstream electronic automation manipulators and vacuum generators directly, supporting quick replacement without modifying original equipment.
How to Use
First, confirm workpiece type before installation: select this integrated check valve suction nozzle specially for porous PCB boards, FPC flexible circuits and test tubes; not recommended for fully sealed smooth workpieces. Check suction lip integrity, internal valve flexibility and suction channel blockage in advance. Second, clean tiny dust, solder residues and particle debris on PCB surface and suction nozzle contact face thoroughly, because fine particles will affect the sealing performance of built-in check valve and cause subtle air leakage. Third, install the integrated PCB suction nozzle firmly on manipulator end fixture, keep vertical grabbing posture to ensure uniform stress on the internal one-way valve during adsorption. Fourth, connect vacuum pipeline and perform idle test, verify flexible opening and closing of internal check valve, confirm no overall vacuum pressure attenuation and smooth airflow switching. Fifth, conduct trial grabbing test on real PCB boards and test tubes, check that the check valve automatically seals leakage points when covering board via holes, ensure stable suction without workpiece shaking or dropping during high-speed movement and positioning. Sixth, launch formal automated circuit board testing and handling production after debugging. For daily maintenance, regularly clean tiny dust blocked inside suction nozzle airflow holes; avoid hard extrusion damaging internal check valve core; replace the suction nozzle timely if suction response slows down or anti-static performance declines.
