Key Differences Between Sorting Transfer Stations and Standard Transfer Stations

Key Differences Between Sorting Transfer Stations and Standard Transfer Stations

Functional Variations

Sorting Transfer Station:

Features sorting functionality, capable of automatically distinguishing between OK boards and NG boards (e.g., post-AOI inspection). NG boards are temporarily stored via multi-tiered buffering racks (typically 10 tiers), with an alarm triggering manual intervention upon tier saturation.

Supports ‌Caching Mode‌: When upstream/downstream process cycle times are mismatched, it can temporarily store PCBs (e.g., 10-layer capacity). Boards are released layer-by-layer upon receiving signals from downstream equipment.

Select models feature ‌Dust Covers‌ (transparent acrylic/PC material) to prevent PCB contamination from dust or flux volatiles, suitable for processes before/after reflow/wave soldering.

‌Standard Transfer Station‌:

Provides only basic transfer functionality without sorting or buffering capabilities, requiring manual intervention for handling abnormal boards.

Some models support manual width adjustment but can only hold a single PCB during operation, requiring sensor confirmation of board delivery before accepting the next piece.

Structural Design

Screening transfer stations typically incorporate lifting buffer zones, photoelectric sensors, PLC control systems, and multi-tiered temporary storage racks. Standard transfer stations feature simpler construction, comprising only conveyor tracks and basic electrical control cabinets.

‌Applicable Scenarios‌

Screening transfer stations are suited for SMT production lines demanding high precision and cleanliness (e.g., automotive electronics, medical devices), requiring integration with inspection equipment such as AOI/SPI.

Standard transfer stations are predominantly used for low-complexity PCB conveyance, such as single-track manual width adjustment scenarios.
