Modern automobile industry has the characteristics of large-scale production, small volume of vehicle models, rapid variety change and multi-vehicle co-line production. These trends require stamping automation technology to develop towards high flexibility and high efficiency.
Most of the industrial robots used in stamping production line, which have advantages of low procurement cost, high flexibility and easy maintenance.But the six-axis industrial robot is limited by its motion posture，During the transfer of the stamping workpiece from the previous press to the next one, the stamping workpiece must be rotated 180 degrees horizontally, which leads to the complex trajectory of the robot，The problem of stamping workpiece is easy to fall off in the rotation process, which limits the speed of the robot, thus limiting the improvement of production tempo.The horizontal rotary motion of the stamping workpiece requires large space, which is more obvious when handling large stamping parts such as the side wall of the car body.As a result, there is a large gap between the press machines before and after the process, which increases the floor space of the production line, and thus increases a series of costs such as capital investment of the plant.
If can speed up the product operation, reduce the risk, then the problem solved, permanent magnets to replace the traditional mechanical fixture electricity has become the mainstream of the modern way, in the process of the workpiece rotation, no matter how trajectory and tempo, electric permanent magnet claw hand through strong magnetic adsorption, ensure the workpiece does not damage the also don't fall off.
