Brief: We show the practical steps and results so you can judge suitability quickly. This video demonstrates the Automated Buffering Feeding NG/OK Buffer Stocker Precision Motor in action, showcasing its automated buffering and feeding process. You'll see how it efficiently separates OK and NG boards, its precision motor-controlled lifting mechanism, and the PLC-controlled operation that ensures high accuracy and production efficiency.
Related Product Features:
  • Automated buffering, feeding, and balancing for front-end and back-end production processes.
  • PLC and touch screen programmable control with LIFO (Last-In-First-Out) operational mode.
  • Directly conveys OK boards to the next machine while storing NG boards for manual testing.
  • Precision motor-controlled lifting travel ensures repositioning accuracy of 0.1mm.
  • Supports multiple lifting pitch options: 25mm, 50mm, and 75mm for flexible operation.
  • High production cycle capability of 8-12 boards per second for efficient throughput.
  • Available in multiple models (AS-250N, AS-350N) to accommodate different PCB size ranges.
  • Manual or automatic track adjustment options for versatile integration into production lines.
FAQs:
  • What is the main function of the Automated Buffer Stocker?
    The Automated Buffer Stocker provides automated buffering, feeding, and balancing between front-end and back-end production processes. It efficiently separates OK (good) boards, conveying them directly to the next machine, while storing NG (not good) boards for manual inspection and testing.
  • How is the machine controlled and what is its operational accuracy?
    The machine is controlled via a PLC (Programmable Logic Controller) with a touch screen interface, operating in LIFO mode. It features a precision motor that ensures high repositioning accuracy of 0.1mm, with adjustable lifting pitches of 25mm, 50mm, or 75mm to suit various production needs.
  • What are the key differences between the AS-250N and AS-350N models?
    The AS-250N model handles PCB sizes from 70L*50W to 330L*250W and has dimensions of 920L*980W*1800H. The AS-350N model accommodates larger PCBs from 70L*50W to 460L*350W with dimensions of 1020L*1080W*1800H. Both share core features like 0.5KW power, 0-5kg loading capacity, and 8-12/s production cycle.
  • What are the power and utility requirements for operating this buffer stocker?
    The buffer stocker operates on AC220V 50/60Hz power supply with a power consumption of 0.5KW. It requires a gas pressure of 0.4-0.7MPa for pneumatic functions and has a standard conveying height of 900±20mm for seamless integration into production lines.
