4, high security in the work of heavy, dangerous workplaces, or high repetitive industrial production workshop, human employees are prone to negligence and physiological fatigue, resulting in the occurrence of safety accidents, the use of intelligent industrial robots for the production, can maximize the protection of the safety of the workers, will not occur due to negligence or fatigue on the work of the safety of the accident. Detailed>>
Industrial robot shortcomings 1, ease of use is not as good as human due to the complexity of the robot structure and control, the use of industrial robots, employees need to be professionally trained to. If the operation is not appropriate, even a simple action, there may be a big safety accident. In contrast, for some simple processes, it will be much more convenient to be done by human beings.
2, do not have the ability to create an autonomous consciousness of judgment and creativity with emotion is a distinctive feature of human beings, but also human beings are still firmly in the hands of the robot control. In industry, workers can communicate with each other, can analyze the problem in different situations, can deal with emergencies in a timely manner. Robots, on the other hand, "think" according to a specific program, which may paralyze the machine or even cause a safety accident if the environment changes suddenly. In some of the need to add the artistic component of industrial and product design, the robot is more difficult to reach the human level.
3, the smoothness of the operation of the robot's joints is theoretically a point, in fact, the robot's joints have a gap, so it is necessary to consider the smooth operation of the robot under the influence of the gap of the motion vice.
4, the layout of the diversity of an industry used in the industrial robot is based on the industry's process, or the actual working conditions and targeted development, if the process changes, the previous equipment may need to optimize or even some occasions need to be completely pushed to start again. Specifically how to consider the layout design to quickly adapt to the company's new products, new processes. Detailed>>
