What are the structures of injection molding machine manipulators?

The actuator of the injection molding machine manipulator is divided into hand, arm and torso:

1. Hands.

The hand is installed at the front of the arm. The inner hole of the arm is fitted with a drive shaft that transmits the application to the wrist, causing

 it to rotate, extend and bend, and the fingers to open and close.

The structure of the manipulator hand mimics the human finger, which is divided into three types: jointless, fixed joint and free joint. The number

 of fingers can be divided into two fingers, three fingers, four fingers, etc. Among them, the index finger is the most used. According to the shape 

and size of the clamping object, various shapes and sizes of the fixture can be provided to meet the needs of the operation. Hands without fingers generally refer to vacuum or magnetic suction cups.

2. Arms.

The role of the arm is to guide the fingers to accurately grasp the workpiece and deliver it to the desired position. In order for the manipulator to 

work correctly, the three degrees of freedom of the robot arm should be precisely positioned.

3. The trunk.

The trunk is a stand for the arm, power supply and various actuators.
