Application of Cleanroom Semiconductor Stocker Polyurethane Drive Wheel

Stocker polyurethane drive wheel is a wheel for production storage and handling equipment in the cleanroom semiconductor industry. It is made of high-performance NDI polyurethane material with strong mechanical properties, compression deformation resistance and heat resistance. It is mainly used for high-bay warehouse stackers, shuttle vehicles (OHCV/OHT), automatic guided vehicles (AGV) and rail transport vehicles (RGV), automated logistics equipment. It has excellent performance in clean environments such as normal temperature, low-temperature cold storage (-35℃) and special industrial environments.

In the field of semiconductor manufacturing, the storage and handling process of wafers places extremely high demands on cleanliness, stability and efficiency. As a core component dedicated to wafer automated handling equipment, Stocker's polyurethane drive wheel has been widely investigated in automated logistics systems with its excellent material properties and adaptability to working conditions. It is a high-performance drive component for cranes in clean rooms.

Travel drive wheel designed for craft processing

Stocker polyurethane drive wheel is mainly used for wafer production and storage and handling equipment in clean rooms, such as:

• High-bay warehouse stacker

• Aerial travel vehicle (OHT/OHS/OHCV)

• Automatic guided vehicle (AGV)

• Railway transport vehicle (RGV)

• Thin film storage system (Stocker)

In the AMHS (automatic unloading and handling factory system) of semiconductors, it is a key component to achieve accurate handling and circulation of material boxes. Its stable operation directly affects the production line beat, product yield and particle control level of the clean room.

High-performance NDI polyurethane material

Stocker drive wheel adopts high-performance NDI type polyurethane material, which not only has excellent physical and chemical stability, but also adapts to strict clean requirements:

• Strong mechanical properties and resistance to compression deformation

Strong load-bearing capacity, can quickly restore to its original shape after long-term static, and ensure smooth operation of equipment when repeatedly started.

• Excellent heat resistance

Even under high load and high speed operation, the polyurethane material can still maintain stable performance without softening or deformation.

• Widely popular in a wide range of environments

It can work stably in clean environments at room temperature, low-temperature cold storage (-35℃) and even special industrial gas environments without performance degradation.

Material advantages highlight core value

The Stocker polyurethane drive wheel combines an advanced polyurethane formula and precision manufacturing technology, with the following product advantages:

• High rebound: reduce the system, improve operating efficiency, and quickly restore it to its original state after long-term operation.

• Super tear resistance: strong resistance to mechanical damage and increased service life.

• Wear resistance: significantly reduces the generation of particles and pollutants, and maintains a clean room.

• Anti-static and conductive dual-mode selection:

Anti-static type: 10⁸~10⁹ Ω, suitable for most AMHS scenarios

Conductive type: 10³~10⁵ Ω, effectively releases static electricity and protects electronic components

Typical application equipment list

Stocker polyurethane drive wheels can be equipped with the following air clean room automated handling equipment:

Clean manufacturing, promote industrial upgrading

As the semiconductor industry moves towards higher cleanliness levels and more precise manufacturing standards, Stocker polyurethane drive wheels are becoming the selected products of wafer fabs with their high-performance materials, excellent durability and industry customization capabilities.

Whether in an extremely low-temperature cold storage environment or a clean room with strict particle control, the wafer transport polyurethane wheel can always run quietly, drive accurately, and last long, ensuring the efficient and stable operation of the AMHS system.
