SCARA Robot: An Arm’s Length Ahead
Robust Jointed-Arm Robots for Industrial Applications
SCARA robots (Selective Compliance Assembly Robot Arm) are deployed in industrial applications where tasks are performed parallel to a work surface."Designed with an arm-like structure, they facilitate precise work in a short time frame. Unlike the more flexible six-axis robots, SCARA robots have four degrees of freedom, consisting of three rotary axes and one linear axis. The advantage of SCARA robots is their compact footprint, robustness, and cost-effectiveness compared to models with multiple axes. They are also known for their high repeatability and long service life. These attributes, along with their significant press-in forces, make them a popular choice for assembly robots in the electrical and electronics industries. However, SCARA robots are also utilized in other sectors, including pharmaceuticals, food, plastics, and metal processing. They excel in performing repetitive pick-and-place tasks, are well-suited for gluing, joining, and assembly operations, and can reliably operate machinery.
How Are SCARA Robots Constructed?
Serial Kinematics With 3 Rotary Axes and One Linear Axis
SCARA robots feature a fixed base with a rotating swivel arm as the first axis of their kinematics. The rest of the kinematic chain, responsible for moving the robot arm links, is connected to this arm via a joint (second axis). At the end of the second arm, there's an integrated vertical and rotatable Z-axis (the third axis). An end effector, like a gripper, can be attached here, allowing for additional linear movements (the fourth axis). This unique kinematic structure provides precise and flexible motion control capabilities.
SCARA Robots in Industry
From Pick-And-Place to Joining and Bonding
To ensure the reliable, long-term operation of SCARA robots in demanding industrial environments, it's essential to secure their gears and joints with effective seals. Seal performance and service life are influenced by various factors, from professional installation and suitable installation space to diverse operating conditions and the choice of lubricants. The specific requirements for seal properties vary across different applications. Freudenberg Sealing Technologies’ sealing solutions not only deliver dependable sealing but also extend service life. Moreover, our comprehensive services enhance the efficiency of your robotics applications.
High-Performance Materials for SCARA Robots
SCARA robots play a pivotal role in automating industrial processes. They excel at handling delicate components in the 3C industry (Computers, Communications, and Consumer Electronics) and the electronics sector. They are synonymous with speed and precision in pick-and-place operations within the food industry and maintain reliable, high-speed performance, even within compact production cells in metal processing. SCARA robots are proficient at stacking heavy batteries for electric vehicles and find application in clean rooms for processing medical plastic components. Their remarkable adaptability has earned them the nickname 'universal robots'.
The diverse range of potential applications imposes substantial demands on selecting the ideal gasket material. Factors include:
- Pressure and temperatures
- Chemical exposure
- Contamination
- Required service life and maintenance cycles
