What do computer parts, medical devices, and cars have in common? They are all built using assembly robot arms. Assembly lines using robots have become more common in the manufacturing industry worldwide. In fact, automation and robotics are believed to be the only means to achieve a cost-effective assembly line.
With technology advancements in automation control, assembly line robots are now able to complete complex assembly tasks that are not previously possible. Buy industrial robotic arms that you can install and commission quicker as compared to special-purpose assembly equipment from EVS. Our products can be easily configured multiple times with a simple tweak in the program.
Assembly robotic arms are used to automate tasks that involve putting products together including electronic components, machinery, furniture, and automotive assemblies. They often come with 4- to 6-axis arms with a dexterity that is comparable to a human arm. Below are the main assembly robot configurations:
Although these robots have smaller payload capacities, they have unparalleled speed and acceleration. They look like spiders that are mounted on the ceiling with bases composed of motors that help in moving the 3-linked arms.
Their main mechanical axes act in parallel on their face-plates rather than in series. This gives delta robots excellent precision and speed. They normally have 10-mm/sec speeds and can accommodate enhanced repeatability at the tip so they are ideal for assembly processes dealing with small parts.
Short for Selective Compliant Articulated Robot Arm, SCARAs have 4 axes that are perfect for assembly applications with high-speed requirements. They are compliant in the X and Y planes but not in the Z plane. This is useful in assembly tasks like inserting pins into holes without binding.
These robots provide more flexibility, strength, and optimal reach to finish tasks. They have compact designs, are nimble and highly dexterous, and can engage assemblies in all angles. They are the most popular types of robots in the industrial sector.
Robot assembly kits offer standard interfaces that are used for motion guidance and inspection through vision systems. Vision systems help the robots identify a part’s style and locate part features for an accurate assembly process. They guide a robot in picking up components from conveyors. Visual serving also allows robots to translate or rotate pieces to make them fit into other pieces properly.
Assembly robots are also equipped with force-sensing technologies for the precise completion of part assembly tasks such as insertion. Force sensors give feedback to the robot’s controller on the amount of force applied to the parts being assembled. These force-sensing technologies, together with vision systems, produce a cost-effective automated manufacturing line with shorter lead times.
For assembly applications that deal with large operations, they can use synchronized multiple robots to assemble components through cooperative motion control. End effectors composed of servos and positioners with multiple axes can be controlled by the robot to finish multiple assembly tasks in one work cell. Lastly, the end effector of an assembly robot can be custom-designed to accommodate different manufacturing requirements.
Robotic assembly systems are the life of a lot of manufacturing industries because they provide faster results. These flexible systems offer many financial advantages compared to hard automation systems. They can handle a wide array of product families when equipped with the right sensing technologies and can be reconfigured quickly to accommodate product changes without spending too much.
Even if one product line completely disappears, robotic assembly lines can be reprogrammed and deployed for other applications, unlike dedicated assembly systems. Robotic systems can lower expenses while enhancing the capacity and quality of production lines. Their flexibility makes them low-risk but high-return investments.
Below are the main reasons why manufacturing industries choose both big and small assembly robots in their production lines:
Industrial assembly robots increase ergonomics and workplace safety by handling dangerous and repetitive tasks. Assembly robots come with safety devices to keep human workers safe when around the robots.
Assembly robots have great accuracy that helps in reducing quality defects and in decreasing product waste. While human workers can create rejects when they experience fatigue, robots can work non-stop but still produce high-quality results.
Automating the assembly production line decreases the amount of occupied floor space. Thus, allowing you to use the factory floor space for other processes.
Assembly robots undergo strict payload and repeatability tests so they are guaranteed to perform with precision for various applications. They ensure that all products are manufactured with consistency.
Below are the common types of assembly operations that use automated robotic systems:
This process is important in assembly operations because the main task of assembly lines is to bring multiple parts together. Assembly robots can perform various fastening methods such as adhesive/glue dispensing, screwdriving, inserting clips, and ultrasonic welding where car assembly line robots are often used.
Bin picking robots can identify and sort random items from cartons, cases, totes, and bins with high accuracy through vision systems. Assembly robots are ideal solutions for manufacturing lines that process parts from bins.
Assembly part sorting robots help in selecting and sorting parts based on the part’s features such as its geometry, color, marking, and barcode.
Genealogy and traceability of parts are crucial in many production processes. Assembly robots can be used to identify parts with the help of advanced vision systems.
EVS offers agile robots equipped with vision systems and force sensors that are unstoppable. Our robots can work accurately, quickly, tirelessly, and precisely which brings a promising future for automation.
