The stamping robotic arm manipulator is a device developed on the basis of automation equipment and specially developed for the unmanned production of stamping automation according to the characteristics of stamping products. It can replace the man power in terms of stamping, handling, loading and unloading of materials in various stamping stations. The robotic arm manipulator has an important embodiment in saving manpower and labor costs, improving labor and equipment safety, and maintaining product productivity, quality and process stability in the industries of repetitive, dangerous and high-beat product manufacturing. With the development of the stamping automation industry, various arm manipulator have been designed according to different product processes and on-site use environments.  Among them, the most common and most used stamping robots are: connecting rod manipulator, in-mold manipulator, independent manipulator, two-dimensional manipulator, three-dimensional manipulator and so on.

The mechanical arm is mainly composed of three parts: the gripper, the movement mechanism and the control system. The gripper is used to grip the workpiece (or tool). There are various structural forms of gripper according to the shape, size, weight, material and operation requirements of the object to be grasped, such as clamping type, holding type and adsorption type.

The moving mechanism enables the gripper to perform various rotation (swinging), moving or compounding movements to achieve the prescribed action, and to change the position and posture of the grasped object. The independent movement of the movement mechanism such as lifting, telescopic, and rotating is called the degree of freedom of the manipulator.

In order to grab objects in any position and orientation in space, there are 6 degrees of freedom. Degree of freedom is a key parameter for manipulator design. The more degrees of freedom, the more flexibility of the manipulator arm has, and its structure is also more complex. Generally, exclusive manipulators have 2 to 3 degrees of freedom. The control system performs specific actions by controlling the motor of each degree of freedom of the manipulator. At the same time, the information fed back by the sensor is received to form a stable closed-loop control. The core of the control system is usually composed of a micro-control chip such as a single-chip microcomputer or a DSP, and the desired function is realized by programming it.
