Stamping robot problems and improvement program discussion

Stamping robot is an important equipment for gripping and positioning workpieces to complete stamping operations. However, there are some problems in the practical application of press manipulator. In this paper, we will discuss the problems of stamping robot and put forward corresponding improvement programs.

First of all, the positioning accuracy of the press manipulator is sometimes difficult to meet the requirements. In the stamping process, the workpiece needs to be accurately positioned to complete the processing operation after being grasped. However, due to the complex shape of the workpiece and the high requirement of machining accuracy, there is deviation in the positioning process of the manipulator. To solve this problem, a vision system can be used for assisted positioning. The vision system can monitor the position of the workpiece in real time and feed back to the robot to provide more accurate positioning information. At the same time, the vision system can be used to detect and measure the workpiece, detect problems in advance, and ensure the quality and efficiency of processing.

Secondly, the gripping strength of the stamping robot is unstable. In the process of gripping the workpiece, the manipulator needs to adjust the gripping strength according to the shape and material properties of the workpiece. However, the force sensor of the manipulator has problems such as low sensitivity and easy to be affected by the environment, which leads to unstable gripping strength. To improve this problem, it is possible to consider adding force sensors to the manipulator gripper and adjusting the gripping strength through real-time monitoring and feedback. In addition, flexible gripping technology can be used to realize flexible gripping of the workpiece through the manipulator's own flexible structure and control algorithm to improve gripping accuracy and stability.

Third, the operation speed of the stamping robot is relatively low. Stamping operations usually require high efficiency and high speed to complete, and the operating speed of the robot sometimes can not meet the production requirements. In order to improve the operating speed of the manipulator, consideration can be given to increasing the degrees of freedom of the manipulator and optimizing the control algorithm and action planning of the manipulator. In addition, parallel manipulator or distributed manipulator system can be used to improve the overall operating speed through multi-manipulator cooperative work.

Fourth, the system stability of the press manipulator needs to be improved. The working environment of the stamping robot is usually more severe, there are vibration, impact and other factors, which can easily affect the stability of the robot. To solve this problem, you can add compensation devices on the structure of the robot, such as shock absorbers, to reduce the impact of external interference on the robot. In addition, adaptive control or intelligent control algorithms can be used in the control system to adjust and optimize the robot action in real time to improve the stability and adaptability of the system.

Fifth, the maintenance of stamping robot takes up a lot of labor and time costs. As an important equipment, press manipulator needs regular maintenance to ensure its good working condition. However, the traditional maintenance method usually requires downtime for repair, which affects the production efficiency. To solve this problem, an intelligent maintenance system can be used to monitor the operating status of the manipulator through sensors, prejudge the equipment failure in advance, and remotely adjust and maintain the manipulator to reduce downtime and labor costs.

In summary, stamping manipulators have problems such as positioning accuracy, gripping strength, operating speed, system stability and maintenance. In order to improve these problems, corresponding improvement programs can be taken, such as the introduction of vision systems to assist positioning, increase the force sensor to optimize the gripping force, increase the degree of freedom to improve the operating speed, increase the compensation device to improve system stability and the use of intelligent maintenance system to reduce maintenance costs. These improvement programs can improve the working efficiency and stability of the press manipulator, and further improve the overall efficiency of the press production line.
