Assembly Robots: Transforming Assembly Lines

Global competition at the production level has accelerated the industry's need for automation. Manipulator robots such as the RB-KAIROS+ precisely streamline assembly processes, which are very common in manufacturing companies. This article shows how assembly robots are a boost for assembly lines in different industries. Learn more about the assembly tasks that a mobile manipulator can perform.


In the manufacturing and industrial production sectors, efficiency is key. This efficiency involves achieving a reduction in time, increasing production speed and maintaining quality standards.
One of the most frequent, repetitive and demanding tasks is assembly. In the industrial realm, the assembly process represents the joining of multiple parts or components to create a complete final product. It is a repetitive process that requires great precision, which is why the automation of assembly lines is a goal for more and more industries.
Human intervention in assembly can not only slow down the pace of production, but also increase the possibility of errors during manufacturing. These errors represent a significant risk to quality and a higher economic cost.

The introduction of mobile manipulator robots in assembly operations offers a number of benefits:

◼️Flexibility: Mobile manipulators can easily adapt to changes in product design or the assembly process, allowing them to perform a greater number of tasks in more than one location.
◼️Efficiency: By eliminating the need to transport parts and components from one location to another, mobile robots reduce downtime and optimize production time.
◼️Space optimization: RB-KAIROS+ can navigate tight spaces and work in areas of the production floor that might be difficult or impossible for a fixed manipulator arm to reach.
◼️Safety: Mobile robots are equipped with advanced sensors and navigation systems that allow them to avoid obstacles and operate safely in environments shared with human workers.
◼️Cost reduction: Although an initial investment is required, in the medium term, they manage to reduce operating costs by increasing productivity and reducing assembly errors.

The industries that use manipulator robots for assembly are diverse, ranging from automotive to electronics, aerospace and food. A mobile manipulator is used in a variety of ways to carry out precise and efficient assembly tasks, depending on the specific needs of each industry. Here are some of the sectors that implement mobile manipulator robots in assembly processes:
◼️Automotive industry: the use of manipulator robots in the automotive sector is one of the most widespread. They are used to assemble a wide range of components, from engines and transmissions to bodies and electronic systems. This mobile manipulator robot performs tasks such as welding, part assembly, painting, and material handling.
◼️Electronics: In the manufacture of electronic products, such as mobile phones, computers, and medical devices, manipulator robots are used to assemble small, delicate components with pinpoint precision. These robots can place chips, solder components, assemble printed circuit boards, and perform quality tests, ensuring the reliability and performance of electronic products.
◼️Aerospace: A manipulator robot in the aerospace industry can assemble aircraft components, such as wings, fuselages, and propulsion systems. These robots can perform complex tasks in controlled environments, such as composite material handling and high-precision welding, ensuring safety and quality in aircraft manufacturing.
◼️Food industry: In the food industry, manipulator robots are used to assemble products such as food packages, cardboard boxes, and packaging trays. These robots can handle food hygienically and safely, reducing the risk of contamination and ensuring food quality and safety at all times.

In addition to the above-mentioned industries, the use of mobile manipulator robots has also spread to sectors such as the pharmaceutical industry, the plastics industry, the furniture industry, and many others. These robots can perform a wide range of assembly tasks, from attaching caps and labels to joining structural components, adapting to the specific needs of each application.

Mobile manipulator robots are used in a variety of applications within an assembly process in industry, including:
◼️Small Parts Assembly: Small parts assembly involves the delicate handling and placement of very small components within a final product. The mobile manipulator robot accurately picks the parts from a storage container and picks them exactly where they are required in assembly and subsequently secures the parts in place using suitable fastening methods, whether welding, gluing or another joining method.
◼️Classification and selection: the identification and separation of different types of components based on their distinctive characteristics. Using advanced vision systems and sensors, the robot recognizes and classifies parts based on their shape, size, color, or other specific properties. Once identified, it automatically selects the parts needed for assembly, classifying them as required and optimizing the workflow.
◼️Pick & Place: The mobile robot manipulator can pick individual parts from a storage container and transport them to the assembly station. This includes the precise selection of electronic, mechanical, or any other components needed for assembly.
◼️Component placement and fixing: Once the robot has transported the parts to the assembly station, it can place them in their correct position within the product being assembled. This involves the precise alignment of components and their attachment using screws, adhesives, or other fastening methods.
◼️Soldering: To assemble electronic components, the manipulator robot can carry out soldering tasks, whether it is spot soldering, surface soldering, or soldering components through the printed circuit board.
◼️Quality Inspection: The mobile manipulator can perform quality inspection tasks to verify that all parts are properly assembled and working as intended. This can include functional testing, strength testing, and verification of dimensional tolerances.
