What is an NG/OK Buffer?
An NG/OK buffer is an intelligent device used in SMT production lines. It is mainly used to temporarily store tested qualified (OK) and unqualified (NG) PCB boards, providing convenience for subsequent production and testing.
What are the technical features?
- Human-machine interface control operation and function switching are simple and easier to understand.
- PLC control system, multiple electrical circuit protection design, safe and stable.
- The temporary storage area has 25 pitches for stopping boards.
- Comprehensive multiple functions, first-in-first-out, straight-through, NG/OK.
- Servo positioning system, accurate positioning, fast lifting speed, high production efficiency.
- Standard SMEMA signal communication method.
What are the main functions?
- Automatic classification function: By connecting with the inspection equipment (such as AOI or SPI), the inspection results are obtained in real-time, and the PCB boards are divided into NG and OK categories for storage.
- Intelligent temporary storage function: According to the preset rules, NG and OK boards are stored separately for subsequent processing.
- Alarm and prompt function: When the temporary storage area is full or the equipment is abnormal, prompts are automatically issued to ensure the normal operation of the production line.
- Flexible docking: It can be seamlessly connected with SMT equipment of different brands to achieve overall optimization of the automated production line.
What are the advantages?
- Improve efficiency: reduce the time of manual sorting and handling, and optimize the smoothness of the production line.
- Reduce labor costs: automated equipment replaces traditional manual sorting operations, reducing staffing requirements.
- Improve accuracy: direct communication with testing equipment, and accurate classification.
- Improve production environment: centralize the management of unqualified boards to avoid confusion or misoperation.
- Facilitate subsequent processing: NG boards are temporarily stored in a unified manner to facilitate maintenance and rework; OK boards quickly enter the next link to ensure production rhythm.
Compared with traditional equipment
- Traditional method: Manual sorting and handling of NG/OK boards, which is time-consuming and prone to errors.
- NG/OK Buffer: automatically completes classification, storage, and prompting, significantly improving efficiency and reliability.
What are the usage scenarios?
- SMT production line: Used in conjunction with AOI, SPI, and other testing equipment for quality inspection and circulation of PCB boards.
- PCB processing plant: Temporarily stores qualified OK and unqualified NG boards during the production process.
- Electronic assembly line: Classify and temporarily store PCB boards for mobile phones, tablets, automotive electronics, and other electronic products.
