Universal Arm and Magnetic Bases

The universal arm and magnetic bases are the robotic devices that are implemented in multiple engineering, manufacturing and science settings as the aid in picking up, holding and placing tasks. The universal arm is also referred to as the universal robot or collaborative robot. The universal robot arm has the appearance similar to a lamp stand with several joints. The joints that the universal arm has allow the robot to conduct a wide range of tasks with almost limited movements. The universal arm can be mounted to a magnetic base in order to attach the arm temporarily onto a determined metal surface. The magnetic bases are often referred to as the magnetic switch bases. The universal arm & magnetic bases are widely applied in assembly, dispensing, machine tending, material handling, removing, welding quality inspection and more.


Universal Robot Arms

The universal robot arm is like a stand with several joints. Each joint on a universal arm represents a moving axis. A joint on the arm allows a 360 degrees rotation capability. Two joints allow the rotations in two orientations. With more joints on the robotic arm, there is more possibility to the movement the arm can make. Since the movement of the universal arm is limitless, it is ideal to perform delicate tasks in the automated operations with. In addition, the movements are controlled by the computer, the precision of the movement is guaranteed therefore. As a result, the universal arms are widely implemented in industries where automation and precision are required.

Besides the stand-style robot arms, there are also the gooseneck style universal arms. The mechanical construction of these two types of robot arm is very different. The universal robotic arms are pieces of rods that are connected by movable joints while the gooseneck arms are actually a spring coil. The strength and flexibility comes from the high strength steel. These two types of arms are used for different types of tasks.


Magnetic Bases

The magnetic bases are the device that helps light weighted equipment to attach onto metal surfaces. This type of machine has the identical working principle to the magnetic lifters. Inside the magnetic base, there is permanent magnet that is used to create magnetic field. The magnetic field can be turned on and off. When the base is turned on, it becomes magnetic and can attach to metals; when the base is turned off, it becomes non-magnetic and cannot attach to metals.

There are two general varieties of the magnetic bases: the button style magnetic bases and the switch style ones. The way these magnetic bases works is actually the same but the mechanism they are turned on and off. The button style bases have buttons to push; the switch magnetic bases has a switch or a lever to control the on and off of the device. On top of the magnetic base, there is a hole to install a machine, typically a universal arm. With the magnetic base, the universal arm can be attached to a metal surface at almost every angle based on the task it is involved.


Material Handling

The most common application of universal arm & Magnetic bases is material handling and placing. In such application, the arm will be attached to a work table with the magnetic base and there will be a clamp or claws on the arm to hold materials or object. The arm is used to hold an object in position for processing, or it is used to retrieve an object from a working station. The benefit of using the universal arm in material handling is that is to relieve the workers from repetitive work and reduce errors, and improve the efficiency.


Assembly

The universal arm & magnetic bases are used heavily in assembly line automation as well. In an assembly line, the repetitive works, such as screw driving, nut driving, part fitting, inserting or lifting, are commonly conducted by the robotic arms because the efficiency and precision of work that are assured by the arm can profoundly cut the assembly time and improve the productivity. With the application of universal arms, the assembly and production can be optimized.


Material Removal

The material removal application refers to the machining operations such as grinding, milling, drilling, boring, routing, etc. In these machining operations, the universal robot arms are equipped with drill bits or cutting tools. Since the arms are allowed with excellent freedom of movement, the machining operations can be performed at almost every angle on the work pieces.
