TURIN Ten misunderstandings about the application of industrial robots

Today, TURIN will talk about the top ten misunderstandings of industrial robot applications. Robot investments typically range from tens of thousands to millions of dollars. It's important to make the right choices the first time and avoid common mistakes that can lead to unnecessary costs or delays in tasks. In order to help engineers and designers avoid the most serious mistakes, we have listed the top ten mistakes in industrial robot applications for everyone to learn from.

TURIN Ten misunderstandings about the application of industrial robots(图1)

One: Underestimating Payload and Inertia

The first mistake robot users make in industrial robotics applications is that they underestimate payload and inertia requirements. Usually, the weight of the tool mounted on the end of the arm is not included in the load calculation. The second reason for this error is that the inertial forces generated by eccentric loads are underestimated or completely ignored.


Inertial forces can overload the robot axes. In industrial robots, overloading of the rotating shaft is very common. If this problem is not corrected, industrial robots will suffer. Reduce the load or reduce the speed parameter to stop compensating for this condition. However, reducing speed increases unnecessary cycle time—cycles that are part of a reduced return on investment are the number one factor in purchasing a robot. This is why load-related factors are so important from the start.


Payload is very important. Some information given by common robot technical parameters is explained in detail. The rated load is only valid when the rated speed is reached. One of the important conditions for reaching the maximum load is to reduce the operating speed of the industrial robot. Also, an excessive load may damage the accuracy of the robot.

Two: Trying to make robots do too much

The robot's flair and flexibility have designers asking it to take on too much work and overcomplicating the robotic cell. Once this result is produced, it can be difficult to achieve the correct cycle time, or introduce additional difficulties to the processing scheme, resulting in massive difficulties caused by processor speed limitations. And once the consumption is defective, this error is often amplified. On the consumption side, unplanned shutdowns will result in huge losses.


Another situation is that the use of industrial robots and work cells exceeds the requirements of the original design. The added work is just after the simulation, which can easily present a disappointing situation. In particular, the regular cycle may not be reached if new simulations are not conducted prior to the promotion plan. Therefore, if we want to ensure that a cycle of the robot is within the specified time, we must pay attention to things beyond the scope of industrial robots.


Before using an industrial robot, it is necessary to simulate the design requirements to confirm the travel load and cycle time of the industrial robot application. Assuming that new applications of robots will be added, certain research will be suspended before entering.

Three: Underestimating cable management

Simple as it may seem, cable management is often overloaded by looking too simple. However, optimizing the path of cables or peripherals for tools mounted at the end of an industrial robot arm is important for the movement of industrial robotic equipment. Lack of estimates of potential problems can cause robots to take unnecessary actions to avoid cable entanglement and compression. Also, assuming not using dynamic cables or reducing cable stress can lead to wire damage and downtime.


At present, the end effectors of industrial robots are usually driven by gas or electrical appliances, and there will inevitably be corresponding gas pipes or cable connections. Most of the gas circuits and circuits of industrial robots are outside, so pay attention to the motion control part of the robot; cable management only needs to be considered when the arm and end effector are moving relative to each other.


Four: Questions to consider before choosing a system

After thinking about each application and system installation, you can be sure that every aspect of the application is your needs, and avoid serious overruns caused by possible errors.


In addition to these, the work schedule of industrial robots is also one of the issues to be considered. When the stroke is positive, it is impossible to judge whether it can meet the application requirements only based on the stroke of the technical parameters of the industrial robot. It is necessary to wait until the end effector is installed to determine whether the motion trajectory of the robot can meet the travel requirements. This is one of the key reasons why industrial robots stop simulating.


According to the environment, there will be customized industrial robots in different environments. For example, the spraying industry requires industrial robots with explosion-proof capability, which is different from the use of standard robots and clean rooms. The reliability, defect rate, and power consumption of industrial robots are all issues that must be considered when selecting robots.

Five: Misunderstandings about accuracy and repeatability

An accurate machine is repeatable, but a repeatable machine is not necessarily accurate. Repeatability refers to the precise reciprocating motion of a robot between given positions according to a regular working path.


Accuracy is expressed in terms of the exact movement of the work path to the calculation point. In the transport movement, the robot takes advantage of the precise performance of the robot by calculating the movement to some fixed positions. Accuracy is directly related to the mechanical tolerance and precision of the robotic arm.


Accuracy has a lot to do with the mechanical accuracy of the robotic arm. The higher the accuracy, the higher the guaranteed speed. The industrial robot reducer is an important key structure to ensure the accuracy of the robot.

Six: only look at the advantages and disadvantages of the control system

Most robot manufacturers think more about the controller of the robot than the mechanical properties. However, assuming that once the robot is configured, the uptime is mainly determined by the durability of the machine. The loss of product consumption capacity is probably not due to poor controllers and electronic equipment, but poor mechanical properties.


In general, the selection of an industrial robot system is based on the user's knowledge of the controller and software. Assuming the robot also has excellent mechanical properties, that would be a very competitive advantage. Conversely, if the robot needs to be stopped from time to time after installation, the time-saving benefits of control can be quickly eroded.


The mechanical part is the key to ensuring the performance of industrial robots. Accuracy, speed and durability are all closely related to the mechanical part. The mechanism of the robot is relatively simple, and the common ones are the motor and the reducer. It's easy to assume that the chosen robot will often require repairs to reducers or other mechanical structures.


Seven: Not having the right knowledge of robotics

Robot manufacturers and system integrators typically design robotic cells for one application. However, if users do not have the right knowledge of bots, they may face failure. The usage time of any consumer device is closely related to how the user uses and maintains the device. It is not uncommon for some first-time users to refuse training. A necessary condition for a robot to continue to work properly is to fully understand the robot's talents and make the best use of it within the scope of work.


An industrial robot is a very special kind of equipment whose operational complexity is no less than that of a CNC machine tool. Similarly, when using robots, you must be familiar with the basic safe operation methods of industrial robots, otherwise it will be very unsafe for equipment and personnel. Operators using the robot must receive safe operation training organized by the system manufacturer to operate.

Eight: Ignore related equipment for robotic applications

A teach pendant, communication cable, and some special software are usually required, but are easy to forget in the initial sequence. These will cause the entire program to be delayed and over budget. When choosing industrial robot products correctly, you must first focus on your own comprehensive needs and meet all aspects of equipment selection. It is not uncommon for customers to sometimes fail to integrate some critical equipment and robots in order to save money.

At the beginning of the project, it is necessary to understand a series of content such as related equipment and software required for the project. During the procurement process, the relevant products should be ordered according to the application requirements of the project.


Nine: Overestimate or underestimate robot control systems

Overestimating the capabilities of an industrial robot control system can lead to duplication of investment and waste in the system. It is common to use double backups on safety circuits. However, overestimating the capabilities of the control system can lead to additional equipment costs, rework and delay costs. Trying to control too many I/O ports and adding servos is a common mistake.


Security controls are a very important issue. While considering safety, it is also necessary to optimize the safety logic signals of the application as much as possible. There is no need for repetition in the program.

10: Don't consider robotics

Limited by the investment scope of industrial robots, people who lack robot knowledge have tried to adopt robots in the past and failed, which is the reason why many people stay away from robots. However, getting rid of the wrong robotics in this regard is very important in order to win in the market competition. However, in many cases, it can help overall consumption efficiency, market response time, improve consumption efficiency, simple operation, flexibility, reusability, reliability, precision and control, and can be used for a long time. These are important reasons to adopt industrial robotics.
