System Description
The Sigma benchtop is a compact three-axis robotic gantry ideal for automating a variety
of dispensing and coating applications. Featuring multiple mounting positions, users can
easily incorporate multiple chemistries or application techniques into their process. With
remote programming capability and image background import, programs can be quickly
uploaded from your desktop utilizing Sigma’s internal 2.4 GHz Wi-Fi network.
Personal Protective Equipment
Workcell operation includes air pressure, electrical power, mechanical devices, and the use
of hazardous materials. Only qualified personnel can operate and service workcells.
Operators must use eye protection because material contents are under pressure. Always
wear gloves when handling materials and solvents. Refer to MSDS sheets on the material
that is used for other precautions.
Best Practices
•Do not wear loose clothes or jewelry when you operate the workcell
•Do not touch the dispense head while it is moving
•Make sure cables and pneumatics hoses are attached and do not cross walkways
•Immediately engage the Emergency Stop button if personnel is in danger
•Locate and define all safety labels on and around the workcell before you turn the
machine “On”
•There must be two people during maintenance procedures
•Dispose of all used parts and materials in accordance with local laws and
regulations
•Safety is a joint responsibility between the OEM and the end-user. All precautions
and practices should be in accordance with local regulations.
DO NOT use incompatible tools, remove door interlocks or bypass safety devices,
make custom mechanics or fluid delivery modification, or change material from the
original design.
