Operation process and optimization improvement of stamping robots

Stamping robot is one of the important equipments in the automated production line, which is used to take down the finished parts on the stamping press and handle them or the next operation. Its operation process generally includes the following steps: positioning, gripping, handling, placing and repositioning. When carrying out the operation of the press manipulator, it can be optimized and improved in the following aspects.

First is the positioning operation. Positioning operation is the step of press manipulator operation, which is mainly used to determine the position of the parts to be handled by sensors or vision systems. In order to improve the accuracy and speed of positioning, it can be done by updating the sensor equipment, choosing more highly accurate sensors or using advanced vision systems. In addition, a positioning calibration device between the robot and the press can be used to ensure the precise positioning of the robot.

Next is the gripping operation. The gripping operation is the process of removing the positioned parts from the press. In order to improve the stability and efficiency of gripping, more flexible gripping devices can be considered, such as pneumatic grippers or electromagnetic suction cups, to adapt to different shapes and sizes of parts. In addition, force sensors can be added to monitor the gripping strength in real time to avoid damage or dropping of parts.

The third is the handling operation. Handling operation is the process of transporting the gripped parts from the press to the designated location. In order to improve the accuracy and speed of handling, multi-axis manipulators such as robotic arm telescopic axes and rotary axes can be considered to improve the flexibility and adaptability of the manipulator. In addition, auxiliary equipment such as vision systems or laser rangefinders can be used to detect the distance and attitude between the workpiece and the target position to help the manipulator complete the handling operation more accurately.

The fourth is the placement operation. Placement operation is the process of placing the handled parts into the designated position. In order to improve the accuracy and stability of the placement, you can consider the use of height-adjustable worktable or conveyor belt, so that the robot can be placed at the appropriate height for the operation. In addition, the gap between the part and the target position can be detected by adding sensors or a vision system to ensure that the part can be placed to the target position in a complete and smooth manner.

It is the homing operation. The homing operation is the process by which the manipulator returns the gripping device to its initial position. In order to improve the speed and accuracy of homing, the return path of the manipulator can be optimized by choosing a more efficient motion path planning algorithm, while reducing the no-load motion time. In addition, it can be considered to increase the sensor equipment of the robot itself to ensure that the robot can accurately return to the initial position.

In conclusion, optimizing and improving the operation process of the press manipulator can improve the efficiency and stability of the production line and reduce human errors and accidents. By means of updating equipment, improving operation methods and adding sensors, the operation process of the manipulator can be continuously improved and the overall efficiency of the automated production line can be further enhanced.
