Single Axis Robot GuideSingle-axis robot in the manufacturing sector is the automation devices that help in the manufacturing industry with only one singly movement direction installed and designed onto that device. The design of a single-axis robot allows for only one direction but often with back and forth designs, and this feature of a single-axis robot not only defines one unilateral direction only, but it also makes it moving forward and backward steadily.
Such design of the single-axis robot is very common in the area of a mechanical movement mechanism for the production line, and the purposes are many. Some may be linear guideways that are installed as one axis of the robotic arm, some others may be a part of machinery that works as the transmission measures. The realization of a single-axis robot varies from one to another. The form of a single axis can be different though, the main functionality is still a single axis of movement.
Single Axis as Linear Guide
A linear-guide way is a bearing designed to provide free motion in one single direction. There are many different kinds of linear guideways. Some powered linear guideways such as machine slides, working tables, roller tables, and some dovetail slides are bearings moved by drive mechanisms. Meanwhile, not all linear guideways are powered, and those non-powered dovetail slides, ball-bearing slides, and roller slides provide low-friction linear movement for equipment that is powered by inertia or by hand. With the powered linear guides, many are activated by linear motors.
In the design of machinery movement, a linear motor is a device designed to convert one form of energy source into linear mechanical energy. One of the most commonly known examples is the heat engines, such as the internal combustion engine, which burn fuel to create heat which is then used to do work afterward. 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. Single-axis robots can be recognized in a way that their movements are triggered can be various.
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 in different directions and phases which are based on the box-in-box ways just like oil country turning machines. Contrary to the turning based machinery, machining centers cover a wide variety of various operations and range a wide scale from single tiny parts to heavy and large milling operation tasks concerning complicated profiles, so some axis of them are installed with the linear guide units for heavy but precision machining processes under the strict surveillance of human operators as well as computer-based real-time inspections.
This kind of single-axis robotic guideway usages of the eventual output of the integrated machinery features can do the best use for the hardened or thick workpieces just like ordinary milling machining does with the single-axis workings. For example, many 5 axis machining centers are equipped with linear guideways to ensure certain specific types of machining, and the result is highly appraised.
In the conventional robot design, ordinary servo motors including both DC and AC motors are commonly adopted in robotic science. Recently, the AC servo motors are also widely used because the control is getting easier than before, yet these motors can still handle a better torque force for the movement. Meanwhile, the prices of servo motors are generally higher, so standard sensors installed are optical sensors with selected resolutions. With the introduction of the BLDC motor, now industrial robotic arms are able to move objects with heavier weights with a great precision level while the cost is not as much as other alternative solutions. Therefore, there are many robotic arms that are utilized in the industry are installed with the brushless DC motors, granting the best optimal final output of the end quality for the production lines.
Most robotic arms are designed with more than one axis since only one axis would be too limited to the working patterns of the modern manufacturing industry to perform the common daily working situations. However, some industrial sectors may only need one axis instead of many, which is a case of the single-axis robot to be used for the maximum benefits with its simple design. For these kinds of usages, the linear transmission functionality is quite a popular field that is utilized by many business owners to deliver ultra-precision and accurate workpieces one direction up rather than the other way around.
