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
