1. Product Overview
The inspection rotary table is a high-precision indexing rotary platform for CCD visual inspection, electrical testing and sorting equipment. It uses servo indexing or direct-drive rotary motion to transfer components sequentially through multiple working stations, completing feeding, vision inspection, electrical probing, marking, and defective part rejection in one continuous cycle.
Commonly made of optical glass or precision aluminum alloy, this rotary fixture features high flatness, low runout and stable indexing repeatability. It is widely adopted for semiconductor chips, LED dies, electronic connectors, precision hardware and MEMS components in cleanroom mass-production inspection lines.
2. Core Features & Advantages
- Multi-Station Indexing Design Custom number of stations (4/6/8/12/16/24 stations) to arrange vision cameras, probes, marking and blow-off stations. Parallel processing improves throughput and UPH.
- High Flatness & Low Runout Precision surface grinding and lapping. Glass version delivers high light transmittance for backlight vision inspection; aluminum alloy version features high rigidity and vacuum adsorption grooves.
- Servo / Cam Indexing Drive Option Servo-controlled indexing supports adjustable speed and angle; cam divider version provides stable high-speed intermittent rotation, low vibration and consistent positioning.
- High Positioning Repeatability Closed-loop encoder feedback controls angular repeatability, ensuring parts align accurately under CCD cameras and test probes to reduce measurement fluctuation.
- Optional Vacuum Groove & Fixture Pocket Custom part pockets, vacuum suction channels and positioning pins for small and fragile components, preventing shifting during rotation and imaging.
- Cleanroom-Friendly Surface Treatment Hard anodizing for aluminum versions; polished optical glass with low particle release, suitable for Class 100 / Class 1000 semiconductor packaging environments.
- Fully Customizable Dimensions Custom outer diameter, station layout, pocket shape, mounting interface and drive mode based on machine footprint and product size.
3. Typical Applications
- Semiconductor: LED, Mini/Micro LED, discrete IC, diode appearance inspection and electrical sorting
- 3C Electronics: Connector pin inspection, camera module component defect screening
- Precision Hardware: Screw, pin, turning part dimension and crack detection
- Medical & Optics: Small optical part, lens component visual inspection
- Matching equipment: CCD vision sorters, electrical test handlers, laser marking machines

5. Operation & Maintenance Notes
- Protect the working surface from scratches. Glass turntables are brittle; avoid hard impact.
- Keep the surface clean; dust, glue residue and metal chips will affect imaging accuracy.
- Check indexing repeatability periodically. Adjust servo home position or cam clearance if misalignment occurs.
- For vacuum type models, regularly inspect air channels for blockage to avoid component slippage.
- Do not overload beyond the design load; excessive load increases runout and accelerates bearing wear.
