Introduce
A 6-axis robot arm is an automatic mechanical machine with 6-axis joints, corresponding to 6 degrees of freedom. This allows the robot arm to move freely within its range without being limited by any translation or rotation. Therefore, 6-axis robot arms are a very important part of large, continuous production lines that need high precision.
Currently, there are many large-scale industrial production lines requiring high precision and automation such as auxiliary lines in the automobile manufacturing industry: welding, painting, assembly, etc. The 6-axis robot arm is an indispensable part of the above lines to ensure production progress and accuracy as required.
Overview of 6-axis robot arm
Main elements in a 6-axis robot arm
Axis of motion and degrees of freedom: The arm consists of 6 rotating axes driven by 6 servo motors attached directly to them. The first axis is the largest axis of the arm, corresponding to 1 rotation step, mounted closest to the base, and axis 6 is the smallest axis of the arm, attached to the main working mechanism of the machine.
Materials and structure: Robot arms are often assembled from durable and flexible materials such as aluminum and steel. The choice of material for the arm’s structural details is often based on the working characteristics and weight and size requirements of the arm.
Size and weight: The selection of the size of the robot arm must be based on the working characteristics, the volume of the goods, and from there the mass of the arm can be calculated to suit the line and factory. Large arms with longer reach can carry large loads or handle larger products, while small arms can be inserted into smaller locations in products that require greater precision. higher precision.
Characteristics of 6-axis robot arm
Speed and accuracy: The 6-axis robot arm is controlled by 6 servo motors, so the rotation speed of the axes, processing speed, and accuracy are all very high and can be customized to suit working needs.
Package weight: Depending on the size and design of the machine, the robot arm can work with small to large volumes of goods, up to hundreds of kilograms.
Working scope: The largest working range of a 6-axis robot arm is the entire half-bridge, not counting the size of the arm, with a radius equal to the distance between servo 1 and servo 6 when all 6 motors are in line, the center of the half. The bridge is located at the position of servo 1
Application of 6 axis machine arm
Manufacturing and assembly industry
Automotive industry: 6-axis robot arms are used for machining and finishing in many production stages of the automobile industry such as frame structure welding, welding, shell machining, painting, assembly, etc. Commonly used types of robotic arms is a medium to large type, able to work with loads up to hundreds of kilograms.
Electronic industry: With a variety of designs, sizes, and product types, robot arms are especially useful in painting, assembling, and arranging components in the electronics industry. For items with small electronic circuits that require high precision, choosing a machine arm to ensure product quality is essential.
Aviation industry: Similar to the above two industries, robot arms are also widely used in the production of shells, furniture, electronic components,… serving the aviation industry.
Material handling and packaging
Logistics: For large warehouses that require precise quantity, location and type of products in the warehouse in real time, using multiple machine arms combined with a control panel will accurately classify items. location, quantity, and possible movement of them for transportation.
Food industry: Robot arms are often not directly applied in product production in the food and beverage industry, they are often used in packaging, sorting, and arranging products in this industry.
Medical and health care
Surgical procedure: Currently, robotic arms can assist doctors in a number of surgical procedures such as suturing, tissue cutting, cell surgery, etc. due to their precision characteristics.
Rehabilitation: With the ability to move without any degree of freedom restriction, 6-axis robots are also used to support rehabilitation for patients with accidents, injuries, post-surgery, etc.
Research and development
Research room automation: With the characteristics of precision and diversity in size, 6-axis robot arms are also applied in research environments that require high accuracy to be able to perform observations and experiments with the desired results. want.
Product development: With the continuous development of electronic technology, materials, mechanical engineering, information technology, etc., 6-axis robot arms are increasingly expanding in terms of control ability, accuracy, size, and mass. work volume,… and can assist in research and production of many products and items, as well as participate in support in many different industries.
Benefits of using a 6-axis robot arm
Using 6-axis robotic arms brings many important benefits, including increased productivity and production efficiency. Thanks to the flexible structure of this arm, the working process becomes more powerful, helping to improve the responsiveness of the production system.
At the same time, the flexibility of the 6-axis robot arm also brings benefits in terms of accuracy and iteration during task performance. The robot’s multi-dimensional movement ability helps precise position and pressure, thereby significantly improving the repeatability of production steps.
