Building cell phones with robots

An automated assembly line consisting of twelve stations that combine to automatically load, assemble, process and unload parts for cell phones has been developed by Euless, TX-based Spectra Technologies.

An automated assembly line consisting of twelve stations that combine to automatically load, assemble, process and unload parts for cell phones has been developed by Euless, TX-based Spectra Technologies for Eimo Americas of Vicksburg, MI.

Ten of the twelve stations in the line use SpectraFlex Modular Process Platforms (MPP) equipped with Stäubli RX-60 six axis robots and CS7B controllers. An asynchronous conveyor transfers pallets between stations that then load and unload parts from or to a tray, pick and place gaskets or protective covers to the cell phone housing, and glue parts of the phone together.

Each MPP work cell is identical except for custom tooling, process devices and process specific programming, so the stations can be reconfigured for new processes as required.

For the cell phone housing assembly line, the Staubli RX-60 robot is mounted to the upper mounting plate in the MPP. This provides an open tabletop in the work area. The Stäubli CS7B controller is mounted in the base of the machine along with the control enclosure for easy access and maintenance.

An operator interface for each work cell is provided via a 15-inch touch screen panel PC running WIN 2000 and Adept Windows and a SMEMA interface is used to connect each work cell. Each workstation is connected via an Ethernet cable to a supervisory station where line data can be collected and displayed.
