An industrial robot is a programmable, multi-purpose manipulator with three degrees of freedom or multi-axis automatic control. This is almost the definition of an industrial robot. More and more engineers and entrepreneurs are exploring robotics to optimize workflows in industrial environments. As time has passed and robotics technology has advanced, robot handles have evolved from storage-oriented AGV groups to paving the way for beginners. A robot hand is essentially a tool for movement. However, not every industrial robot resembles a hand. Different robots have different types of structures. A detailed explanation of the internal structure and basic principles of industrial robots is needed.
If you consistently perform the same tasks, you can use an automation solution tailored to your needs. Factories require greater flexibility in handling work. In this case, the right solution is a reprogrammable robot that can attempt a variety of tasks.
Basic industrial robot components
With the development of artificial intelligence, robots are becoming increasingly integrated into our lives.
Research shows that cultural differences influence human perception of robots. People in Lenema saw the Terminator, as did the Japanese. There's also the Aster Boy. There's a link between education level and positive emotions: the higher the education level, the greater the interest in robots. Currently, public opinion towards robots is generally positive.
Using robots can prevent us from doing jobs entirely by humans: integrating robots into our economy to increase productivity and reduce our dependence on mining so that people don't have to make a living most of the time.
Basic components and operating principle of a conventional cylinder:
Cylinder components: cylinder body, piston, sealing ring, magnetic ring (sensor cylinder)
Principle: Compressed air moves the plunger. Changing the intake direction will change the direction of the piston arm's movement.
Fault modes: Piston stuck, not working; cylinder weak, gasket worn, air leaking.
Typical cylinder design and working principle
For example, the double-acting single-rod cylinder is most commonly used in pneumatic systems. It consists of a cylinder, piston, piston rod, front cover, rear cover, and seals. The interior of a double-acting cylinder is divided into two chambers by the piston. The hollow portion of the piston rod is called the rod chamber, and the hollow portion of the piston rod without a piston rod is called the rodless chamber.
When compressed air is introduced from the rodless chamber, the rodless chamber retracts. The pressure difference between the two chambers of the cylinder acts on the piston, exceeding the resistance load, which facilitates piston movement and extends the piston arm; if the rod chamber is used for intake and the rod chamber for exhaust, the piston rod retracts. If there are rod and rodless chambers for alternating intake and exhaust, the piston can move in a linear rotational path.
Design and operation of cylinders without mechanical contact rods
The cylinder structure without a mechanical contact rod is shown in Figure 3. There is a groove along the axial direction of the cylinder tube, and the piston and slider move on top of the groove. To prevent leakage and dust, the cylinder heads at both ends are connected to the openings with polyurethane sealing tape and dustproof stainless steel strips. The plunger frame connects the plunger to the slider through the groove. The piston is connected to the slider to control the actuator connected to the slider, enabling mutual movement.
The characteristics of the cylinder are: 1) Compared with ordinary cylinders, the installation position can be reduced by 1/2 under the same gear; (2) No anti-rotation mechanism is required; 3) Applicable to cylinder diameters of 10~80mm, and when the cylinder diameter is ≥40mm, the maximum gear can reach 7m; 4) High speed, the standard type can reach 0.1~0.5m/s; the fast type can reach 0.3-3.0m/s. Disadvantages: 1) Poor sealing performance, easy to leak. When using a three-position valve, a medium pressure type should be selected; 2) Low load capacity. A control mechanism must be added to improve the load capacity.
Structure and working principle of rack and pinion oscillating cylinder
The shelf and pine wood rotary cylinder is a type of rotary cylinder that rotates via a shelf and pine wood connected to a piston. Its structural principle is shown in Figure 5. The piston moves only in opposite linear directions, resulting in low friction loss, high gear efficiency, and an efficiency of approximately 95%.
Detailed Explanation of the Internal Structure and Basic Principles of Industrial Robots? The design principle of a single-vane rotary cylinder is shown in Figure 6. It consists of a main shaft rotor (output shaft), stator, cylinder body, and front and rear ends. The stator and cylinder are connected together, and the vane and rotor are connected together. The stator has two channels. If the left side is used for air intake, the right side is used for exhaust. Compressed air forces the vane, causing the rotor to rotate clockwise. Conversely, it rotates counterclockwise. A cylinder with a magnetic switch refers to a magnetic ring mounted on the cylinder piston and a magnetic switch directly mounted on the cylinder arm.
