Hey there! I’m a supplier of industrial robots, and over the years, I’ve seen my fair share of issues with these machines. In this blog, I’ll talk about some of the most common faults of industrial robots that I’ve come across in my business. Industrial Robot
1. Mechanical Wear and Tear
One of the most frequent problems we see is mechanical wear and tear. Industrial robots are constantly in motion, performing repetitive tasks. This continuous movement takes a toll on their mechanical components like gears, bearings, and joints.
For example, the gears in a robot’s arm are responsible for transferring power and controlling the movement. Over time, the teeth of the gears can wear down. This can lead to inaccurate movements, as the robot might not be able to position itself precisely. You’ll notice that the robot starts to deviate from its programmed path, which can be a big problem if it’s working on a precision task like assembling small electronic components.
Bearings are another area that gets affected. They allow parts of the robot to rotate smoothly. But with constant use, the lubrication in the bearings can break down, and the balls or rollers inside can start to wear. When this happens, the robot may make strange noises or experience increased friction. This not only affects its performance but can also lead to overheating, which can cause further damage.
Joints are also prone to wear. The constant bending and straightening can cause the seals around the joints to deteriorate, allowing dirt and debris to enter. This can lead to corrosion and reduced flexibility in the joints.
2. Electrical and Electronic Failures
Electrical and electronic failures are also quite common. Industrial robots rely heavily on electrical systems to control their movements, process data, and communicate with other devices.
Faulty wiring is a big culprit. The wires in a robot can get damaged due to repeated bending, vibration, or exposure to harsh environments. A broken wire can disrupt the flow of electricity, causing the robot to malfunction. For instance, if a wire connected to a sensor breaks, the sensor won’t be able to send accurate data to the robot’s control system. This can lead to the robot making incorrect decisions, like picking up the wrong part or colliding with an object.
Electronic components such as circuit boards can also fail. These boards are responsible for processing all the data and sending commands to different parts of the robot. Over time, the soldering on the circuit boards can weaken, or the components themselves can degrade due to heat and electrical stress. When a circuit board fails, it can be a real headache to diagnose and repair, as there are often many components on the board that could be the problem.
Power supply issues are another common problem. If the robot doesn’t receive a stable and proper voltage, it can cause all sorts of problems. For example, a voltage spike can damage sensitive electronic components, while a low voltage can cause the robot to operate sluggishly or not at all.
3. Software Glitches
Software plays a crucial role in the operation of industrial robots. However, it’s not immune to problems.
One of the most common software glitches is programming errors. Even the most experienced programmers can make mistakes, and a single error in the code can cause the robot to behave unexpectedly. For example, a wrong instruction in the code could make the robot move in the wrong direction or perform an incorrect sequence of actions. These errors can be difficult to detect, especially if the robot seems to be working fine most of the time but has intermittent issues.
Software compatibility issues can also arise. As technology evolves, new versions of operating systems and software applications are released. If the robot’s software isn’t updated or isn’t compatible with the new systems, it can lead to problems. For instance, the robot may not be able to communicate properly with other devices in the production line, or it may experience slowdowns or crashes.
Another problem is software bugs. These are unintended errors in the software that can cause the robot to malfunction. Bugs can be introduced during the development process or can be the result of changes made to the software later on. Fixing software bugs can be time – consuming, as it often requires a detailed analysis of the code and extensive testing.
4. Sensor Malfunctions
Sensors are an essential part of industrial robots. They help the robot to interact with its environment, detect objects, and ensure accurate movements. But sensors can malfunction for various reasons.
Dirt and debris can accumulate on the sensors, blocking their ability to detect objects accurately. For example, a vision sensor that is used to identify parts may not be able to see clearly if it’s covered in dust. This can lead to the robot picking up the wrong part or missing parts altogether.
Physical damage to sensors is also a common issue. Robots are often working in harsh environments where they can be exposed to impacts, vibrations, or extreme temperatures. These conditions can damage the sensors, causing them to give inaccurate readings or stop working completely.
Calibration problems can also occur. Sensors need to be calibrated regularly to ensure that they are providing accurate data. If the calibration is off, the robot may make incorrect decisions based on the faulty sensor data. For example, a proximity sensor may indicate that an object is closer or farther away than it actually is, which can cause the robot to collide with the object or miss it.
5. Lack of Maintenance
A lot of the problems I’ve mentioned above can be prevented or minimized with proper maintenance. However, many companies neglect the maintenance of their industrial robots.
Some companies don’t have a regular maintenance schedule. They only address problems when they occur, which can lead to more serious issues down the line. For example, if a company doesn’t lubricate the robot’s bearings regularly, the bearings will wear out faster, and eventually, they may fail completely. This can result in costly downtime and repairs.
Inadequate training of maintenance staff is another issue. Industrial robots are complex machines, and it takes a certain level of expertise to maintain them properly. If the maintenance staff doesn’t have the right training, they may not be able to identify potential problems early or may make mistakes during the maintenance process.
