Linear and Rotary Indexing Systems

Linear and Rotary Indexing Systems

Linear and Rotary Indexing Systems constitute major sub systems that are required in an assembly automation project. Indexing mechanisms operated via camera or gear are driven pneumatically or through servo drives. Pick and place, screw driving and dispensing, crimping, pressing and ultrasonic welding are some of the assembly operations performed on indexers. SCARA robots, machine-vision systems and electrical testing are coupled with indexing systems based on the application type. Choosing between linear and rotary indexers for an automated assembly application is fundamentally dependent on how much space is available on the floor plant.
In comparison, Linear Indexing Systems are better-suited for assemblies that are relatively more complex in nature. Linear Indexing Systems are preferred for inspection and testing process during assembly. This type of indexing system is optimal for plants with narrow aisles. Linear indexing systems, apart from being modular and easily expandable, shuttles assemblies between stations within fractions of a second. Rotary indexers, on the other hand, are used for the assembly of products that are comparatively smaller in size.
