IC694PWR331D As the semiconductor industry continues to evolve, manufacturers are challenged to improve production efficiency and reduce costs. Crane Handling System (OHT) is an important automated handling system in semiconductor manufacturing plants that improves the overall production process by increasing material handling efficiency, reducing labor costs and reducing pollution risks.
What do you know about the Crane Handling System (OHT)?
“OHT” stands for Overhead Hoist Transfer. The main Load transfer components are: wafer loading machine (LPU), load-port Unit and Front Open Unified Pod (FOUP), and the components of the entire OHT handling system are shown as follows:
And in such efficient and complex automation equipment, as a sensor expert, what unique products can play a role.
BPS 8 barcode positioning system
Helps OHT equipment position accurately
Working distance 60~120 mm, compact design, only 60mm blind areaIC694PWR331D especially suitable for compact equipment;
Positioning range 0~10,000,000mm, with high quality BCB bar code belt can fully meet the requirements of walking distance;
Compatible device 4m/s moving speed, fully meet the maximum speed requirements of OHT equipment 3m/s;
5VDC/24VDC (for MA8 adaptation module) Various voltage ranges are suitable for different electronic device power supply requirements;
RS232/RS485 and Modbus data output mode, to provide you with more data choices;
BCB bar codes come with standard 25mm height and 47mm height options, providing customized height and length services.
CR 100 economical fixed bar code reader
With the single bar code attachment, it can realize the economical positioning and speed change signal acquisition of OHT car
Working distance 15~67 mm, compact design is especially suitable for compIC694PWR331D act equipment;
700Hz scanning frequency, with single bar code accessories to meet the requirements of high-speed operation equipment;
5VDC power supply requirements, more PCB control board circuit design;
RS232 data output mode, suitable for single device use.
PRK 3C series sensors
Stability check, every inch of it
In the general purpose OHT vehicle, a photoelectric sensor is needed to detect the presence of FOUP stably. The PRK 3C high-performance photoelectric sensor enables stable detection while ensuring the need for fast response, as well as high-speed triggering of barcode reading products.
The mirror with polarized light lens reflects the photoelectric sensor to ensure the detection stability;
PRK3C.A3 coaxial optical sensor, “0” blind area, even close to the reflector is effective;
1500Hz scanning frequency, the first choice for high-speed sports equipment;
The adjustment function of IO-Link can make the parameter setting more consistent and intelligent one step ahead.
