Analysis of the operation difficulties and solutions of stamping robots

Stamping robot is a commonly used automation equipment in stamping process, and its main function is to clamp, position and carry the workpiece. However, in actual operation, there are some difficulties in stamping robot, how to solve these difficulties is the key to improve the efficiency and quality of stamping process.

First of all, one of the difficulties in the operation of the press manipulator is the stability of the clamped workpiece. Since the stamping process has high requirements for workpiece clamping, unstable clamping will lead to workpiece position deviation, which in turn affects the precision of the stamping process. To solve this problem, the following measures can be taken: one is to optimize the structure of the clamping jaws to ensure that the clamping jaws and the workpiece match to improve the clamping stability; the second is to increase the force of the cylinder to increase the clamping jaws gripping strength to ensure the stability of the clamping; the third is to install sensors to detect and adjust the clamping strength, timely detection of clamping instability and timely correction.

Secondly, the second difficulty in the operation of the press manipulator is the high positioning accuracy requirements of the workpiece. In the stamping process, the workpiece must be accurately placed in the stamping mold, and any positional deviation may lead to stamping failure. In order to solve this problem, the following measures can be taken: first, to improve the positioning accuracy of the workpiece by increasing the positioning device, such as the use of magnetic positioning, photoelectric alignment and other technologies; second, to strengthen the sensing detection of the workpiece, through the sensor to detect the positional offset of the workpiece, and real-time adjustments to the position of the jaws of the manipulator, to maintain the accurate positioning of the workpiece.

Third, the third difficulty in the operation of stamping robot is the protection of the workpiece in the handling process. During the stamping process, the workpiece may be damaged due to the friction or collision of the manipulator, which is especially critical for some workpieces with high requirements for appearance quality. To solve this problem, the following measures can be taken: first, through the action path planning of the robot, reduce the contact area between the robot and the workpiece to reduce the risk of damage; second, optimize the speed and strength control of the robot to ensure the smoothness and accuracy of the operation process and reduce the damage to the workpiece.

Fourth, the fourth of the operating difficulties of the press manipulator is the difficulty in the handling process of complex shaped workpieces. For some complex shapes and curves of the workpiece, the clamping jaws of the manipulator are often difficult to completely fit with the workpiece, thus affecting the stability and accuracy of the handling. To solve this problem, the following measures can be taken: first, increase the adaptive ability of the manipulator, by adjusting the gripping method and angle of the gripper jaws, so that it can fit better with the workpiece; second, increase the flexibility of the manipulator, using multi-axis manipulator or flexible manipulator, to improve the adaptive ability of the complex shape of the workpiece.

In summary, the operational difficulties of the press manipulator include clamping stability, positioning accuracy, workpiece protection and the difficulty of handling complex shaped workpieces. For these difficulties, they can be solved by optimizing the structure of the clamping jaws, adding sensors, increasing the positioning device, optimizing the action path planning, adjusting the speed and strength control of the robot, and increasing the adaptive ability and flexibility of the robot. Only by solving these difficulties, the stamping robot can more stably and accurately complete the stamping process and improve work efficiency and product quality.
