Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "plurality" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0051] The material clamp is a robot gripper mechanism used for automatic loading and transportation of stators and finished products during the assembly of motor stators and rotors. The servo position of the gripper can be automatically adjusted by the program. In the field of motor stator and rotor assembly, there are many types and specifications of stators and rotors, which can be assembled into motors of different specifications through different combinations. During production, multiple sets of grippers are often required for loading, turning, and transportation of stators and assembled finished products. The gripping of various components and specifications can be achieved by replacing the robot grippers. It is impossible to clamp materials of different shapes with one set of grippers.

[0052] In view of this, an embodiment of the present application provides a material clamp to overcome at least one of the above-mentioned technical problems.
