These pre-production systems, frequently for pilot run build-up to full production run rate, are based on standard workstations that can be reconfigured to assemble different part types using rapid change tooling and inter-changeable nests which operate using a Plug and Play concept through a single multi-pin connector. Coded fixtures and tooling allow automatic selection of assembly sequences and operator instructions within the PC-based touch screen controller.
ATM's new medical range control system has an administrator login function, which allows the creation of a detailed sequence of assembly operations to be followed. Along with this, an on-screen training video is also being developed to assist in the part assembly.
The control systems are consistent throughout the range and no specialist programming skills are required. There are three sizes of human machine interface (HMI) systems available – 15.24cm, 30.48cm and 38.1cm – with a standard interface for printers, scanners, sensors, vision systems and torque drivers.
Within the range are Vision and Verification Systems, built upon a standardised and proven concept with a choice of up to eight cameras. These have the capabilities to check colour, part orientation, major and minor part defects, and shape and size of individual parts. Vision systems are programmed to archive all images to a compressed file for later retrieval, enabling electronic audits of part or assembly quality.
BuildAssist can be used for a diverse range of tasks, with a wide selection of technologies that can be used individually or combined to meet different assembly requirements. These include screw feeding and driving, ultrasonic welding, bar code scanning, pneumatic or electric press units, glueing and dispensing systems, and machine vision inspection and verification.
