Multi axis robots in the automation industry are the robotic devices that are designed with multiple axes installed unto the robotic arm shells of the automation system in order to conduct processing, relocations, transmission, and other complicated actions that require precision positioning. This type of mechanical structure can be used to perform accurate relocations of the work pieces on the production lines for onsite workers to process the many following steps of their processing steps, or it can be utilized to cover even more steps that were once handled by human workers in the past time so that the whole procedures would be further improved and smoothed. The inventory of multi axis robotic arm is wide, including 6 axis robot, 8 axis robot, 12 axis robot, etc. The more axes the robot has, the more flexibility the movement can be.
Linear-guide ways can be integrated together to form a multiple direction movement mechanism for the working procedure. It is a bearing designed to provide free motion in one single direction. There are many different kinds of linear guide ways. Some powered linear guide ways such as machine slides, rotary working tables, roller working tables and some dovetail slides with advanced functionality are bearings moved by drive mechanisms.
Not all linear guide ways are powered, and those non-powered dovetail slides, ball bearing slides and roller slides provide low friction linear actions for equipment which is powered by inertia effects or by hand operation. With the powered linear guides, many of them are activated by linear motors. In the design of machinery movement, a linear motor is a device developed to convert one form of energy source into the linear mechanical energy.
One of the most commonly known examples is the heat engines, such as the internal combustion engine machine, which can burn a fuel to create heat that is later utilized to do work for power consumption afterwards. Meanwhile, electric motors convert electrical energy into mechanical motion, and pneumatic motors use compressed air, and clockwork motors in wind-up toys use elastic energy to drive the items with safe and controlled force inside the plastics or metal objects. Based on these features, basically the number of axis can be increased definitely, but now scientists are working on the 6 six robot, 8 axis robot, and 12 Axis robot.
Robotic arms with multiple axes can do as much as human manual processes in a large extent while not one hundred percent though since there are still many parts of jobs need to be taken into consideration by human judgment rather than computer programs. The limitation of computers is the boundaries of the robots’ capacity, and that is why now the world industry is having the AI rush for this solution. In the application of multiple axis robots with the example of the double column machining centers or other heavy duty cutting machine tool models, these kinds of machining processes could be achieved on different directions and phases which are based on the box in box ways just like oil country turning machines controlled by the CNC automatic controllers.
Not like the turning based machinery, CNC automatic machining centers with robotic arms cover a wide variety of various operations and ranges a wide scale from single tiny parts to heavy and large milling operation tasks concerning complicated profiles of work pieces, so there are axes of them that are installed with the linear guide units for heavy duty that request for precision machining standards under the strict surveillance of human operators needed as well as computer based real time inspections.
This kind of single axis robotic guide way usages of the eventual output of the integrated machinery features can do the best use for the harden or thick work pieces just like ordinary milling machining does. For example, many 5 axis machining centers are equipped with the linear guide ways to ensure certain specific types of machining processes, and the result in the industry is highly appraised by users and operators.
Ordinary servo motors including both direct current and alternating current motors are usually adopted in the robotic science for a series of usages. Recently, the AC servo motors are also widely used because the control is getting easier than before, but these motors can still handle better torque forces for the mechanical actions. Meanwhile, the prices of servo motors are generally higher, so standard sensors installed are optical sensors with selected resolution values.
With the introduction of the brushless direct current motor, now industrial based robotic arms are able to move objects with heavier weights with great precision level, and the cost is not as much as other alternative solutions like people faced in the past time. Therefore, there are many robotic arms that are utilized in the industry are installed as a part of the machinery with the brushless DC motors, granting the best optimal working results of the end quality for the production lines in the manufacturing plants.
