Top 10 myths about industrial robotics applications

Myth 1: Underestimating the effective load and inertia

Among the top misunderstandings of robot users in their applications is the underestimation of the effective load and inertia requirements. This is often mostly due to the fact that the weight of the tools installed at the end of the robotic arm is not included when calculating the load. The second reason for this error is to underestimate or completely ignore the inertia generated by the biased load.  

Inertial forces may constitute an overload of the robot's axis. In robots, overloading of the rotating axis is common. Failure to correct this problem can also be harmful to the robot. Reducing the load or reducing the speed parameter can stop compensating for this situation. However, the rate of reduction will increase the cycle time that is not needed - the cycle that is part of the reduction in return on investment ranks first when it comes to buying a robot. This is also why load-related elements are important from the very beginning.  

The payload is very important, and general robot technology parameters give some information, It is detailed that the rated load is effective when the rated speed is applied, and one of the important conditions for reaching the max load is to besides a low robot operating speed, and an excessive load may also break the accuracy of the robot. Lead the charge to change the gun disc and arrange it.

Myth 2: Trying to get robots to do too much.

Sometimes, the ability and flexibility of the robot cause the designer to take on too much work, making the robot unit too complex. Once such an outcome is produced, it is difficult to determine the correct cycle time or creates additional difficulties for the disposal scheme, resulting in significant difficulties due to the disposal speed limit. And once consumption becomes defective, this error is often amplified. In consumption, unplanned shutdowns will incur huge losses.  

Another situation is where the use of robots and work units exceeds the capacity requirements of the original design. When increased work is not added until after simulation, it is easy to present disappointing situations. In particular, the regular period of batching cycles may not be achieved without new emulation before the program is pushed forward. So to ensure that a robot-like period of batching cycles is within a rule, things that are out of the robot-like have to be watched very carefully.  

Before using the robot, it is necessary to go through simulation and simulation, according to the design requirements, confirm the travel load of the robot's application, and also the cycle time, and assume that new applications of the robot are added, stop certain tests before entering.

Myth 3: Underestimating Cable Management Problems

As simple as it appears, or perhaps because it seems too simple, cable management is often overloaded. However, optimizing access to the cable or peripheral equipment of the tool mounted at the end of the manipulator is very important with respect to the motion of the robot equipment. A lack of estimates of potential problems would cause robots to make unwanted movements to avoid entanglement and pressure on the cable. Furthermore, it is assumed that not using dynamic cables or reducing the pressure of the cables may cause damage to the wires and downtime.  

The end-effector currently used is usually gas-driven or electrically driven, and inevitably there will be corresponding trachea or cable connection. Most of the airway and electrical circuits of industrial robots are external, so considerable care should be taken during the movement control of the robot. There are also industrial robots where the airway and electrical circuits are built-in, which is very convenient at this time, simply considering the management of cables when the arm is moving relative to the end actuator.  

Myth 4: Questions to think about before choosing a robot system

After thinking about each application, when the system is installed, you can be sure that all aspects of the application are what you need and avoid serious overruns due to possible errors.  

In addition to these, the robot's work schedule is also one of the issues to consider. When the journey is certain, it is not possible to determine whether the application requirements can be reached only according to the journey of the robot technical parameters, but should theoretically consider whether the robot's trajectory may be reachable after the end actuator is installed. This is one of the key reasons why analog simulations should be discontinued. Pilot quickly change gears and organize.

Regarding the environment, different environments will have customized industrial robots, such as the spraying industry needs explosion-proof industrial robots that are different from standard robots, and the use of clean rooms. The reliability of the robot and its defect rate, the amount of electricity consumed, etc. are also issues that need to be considered when selecting.

Myth 5: Misconceptions about accuracy and reproducibility

A precise machine can be repeated, but a reproducible machine does not necessarily have precision. Repeability refers to the fact that a robot behaves precisely repeatedly between a given position in accordance with a ruled way of working.  

Accuracy is expressed according to the precise movement of the working pathway to a calculated point. In the case of moving motion, the robot has calculated the position of moving to some established points, using the precise performance of the robot. Precision is directly related to mechanical tolerance and the accuracy of robotic arms.  

Precision has a lot to do with the mechanical accuracy of the robot arm. The higher the accuracy, the more accurate it is to ensure an accurate high speed. The robot slowdown is an important key structure to ensure the accuracies of the robot. Normal industrial robots use standard decelerators of the RV type, and given the need for some precision manufacturing applications, consider industrial robots using the robot's ancestral staubliunimation.

Myth 6: Choosing a robot system depends only on the quality of the control system

Most robot manufacturers probably think more about the robot's controller than about its mechanical properties. However, it is assumed that once the robot is configured, the normal operation time is mainly dependent on the durability of the machinery. The loss of consumption capacity of products is likely to be due not to poor controllers and electronic equipment, but to poor mechanical performance.  

The choice of a robot system is usually based on the user's knowledge of the controller and software. Assuming that the robot in this area also has excellent mechanical properties, this will be a very competitive advantage. Conversely, assuming that the robot needs to stop repairs from time to time after installation, the time-saving advantages of knowing the control will quickly be lost.  

The mechanical part is the key to safeguarding the performance of industrial robots in the first place, and accuracy, speed and durability have a great relationship with the mechanical part. The mechanical composition of the robot is relatively simple, usually motors and slowdowns, and it is very easy to assume that the selected robot often needs to service the slowdown parts or other mechanical structures.  

Myth 7: There is no correct robot knowledge

The manufacturer and system integrator of the robot usually design a robot unit for only one application, but if the user does not have the correct knowledge of the robot, it may fail. The use time of any consumer equipment is closely related to how the user uses and maintains the equipment. It is not uncommon for some novice users of robots to be untrained. It is essential to fully understand the capabilities of the robot and use it better within its scope of work.

Industrial robots are very special equipment, and their operation is no less complex than that of a CNC machine tool. Similarly, the use of robots requires familiarity with the basic safety operation knowledge of industrial robots, otherwise it is very unsafe for the equipment and people. The operator of the robot must be allowed to operate the robot after the system manufacturer has completed the safety operation training of the system.

Myth 8: Neglecting the equipment associated with robotics applications

Instruction aids, communication cables, and some special software are often necessary, but can easily be forgotten during the initial ordering. These would cause delays in the entire plan and costs to exceed budget. When choosing a robot product correctly, first of all, think about your comprehensive needs and all aspects of satisfying the equipment selection. It is often the case that customers sometimes fail to integrate some of their key equipment and robots in order to save money.  

At the beginning stage of discontinuation of a project, it is necessary to understand a series of relevant equipment, software, etc. that the project needs to configure. During the procurement process, it is necessary to think about the relevant products ordered according to the application of the project.

Myth 9: Overestimating or underestimating the capabilities of robotic control systems

Estimating the capabilities of a robot control system too low will result in repeated investment in the system and unnecessary costs. The use of double backup on secure circuits is very common. It is a common mistake to try to control too many I / O ports and increase the service system by overestimating the ability of the control system to generate additional equipment costs, rework and lost time costs.  

Security control is a very important issue. While thinking about security, we should also try to optimize the application's security logic signal. There is no need for duplication in the program.  

Myth 10: No thought at all about using robotics.

Constraints on the scope of investment, lack of knowledge about robotics and past failed attempts to adopt robots are reasons for many to stay away from robotics. But in order to improve consumption rates and win in market competition, it is very important to get rid of this aspect of the error robotics technology does not improve consumption rate alone, but in many cases it can help improve overall consumption efficiency. Market response time, Increased consumption efficiency, simple operation, flexibility, reusability, reliability, precision, control capability and long-term availability are all strong reasons for the adoption of robotics.  

Application of robots is a long-term investment that can be managed properly, but also ensures product yield, improves consumption rate, and completely automated applications of factories naturally give customers a stable pillar.  

Therefore, with the emergence of the seventh axis of robots, the application of robots successfully cooperates with robots, making the robots more flexible and utilizing space more extensive, so it is sooner or later that robots will replace human labor.
