Low Cost PCB-board handling system
System for PCB handling over large spans from the back-end of electronics manufacturing for large-scale production with the following specifications:
- Open construction for access of different systems
- High rigidity, vibrations forbidden
- Fully automatic width adjustment for different plate sizes
- High accuracies of linear races to avoid blocking of plates during transport
- Abrasion-free contact surfaces
- Increased system accuracy for parallel assemblies
- Clean room suitable
- Function and quality assurance
Using FEM analysis static and dynamic component optimization was achieved and the tasks implemented as follows:
- Base/bridge construction with cast composite parts
- Self-supporting, highly rigid and preloaded linearways
- Abrasion-resistant linearways with special surface coating
- Automatic width adjustment over linear positioning tables with integrated ballscrew and directly mounted stepper motor drive
- Various manipulators for the plate operated by compressed air and evacuated systems
- All movements and positions supervised by contactless sensor technology
- Supervising control and monitoring of all functions through CAN bus
- Bearings, ballscrew and linearways lubricated with appropriate clean room grease
- 100 % examined precision assembly including optimization of parallelism and angularity
- Function control, examination of compressed air-, vacuum and sensor technology system by application identically sequencing program with 100% of all assemblies simulated and tested
- Test protocol attached at each delivery
