Abstract
Clean benches each providing a sealed work space can be connected together in a row to form a modular system such that objects on pallets can be transported concurrently back and forth from one to another of connected benches through sealed doorways. The pallets have a translucent bottom and lamps are provided below their paths such that the objects thereon can be clearly silhouetted. Each bench is provided with a driving mechanism for a robotic gripper arm such that various tools can be used to automatically perform different tasks in the work space. The main frame of each bench forms a closed air circulating system for providing an air flow through the work space, and fans of different power are arranged in its path such that the air pressure tends to be higher in the work space than elsewhere.
