The composition of an injection manipulator is generally composed of an execution system, a drive system, and a control system. The execution and drive system is mainly designed to complete the normal function of the arm, which uses pneumatic or hydraulic power to drive the operation of mechanical components to achieve the function of fetching objects. The control system controls the drive system to make the execution system operate according to a predetermined process. Take the control system of a simple manipulator as an example:
HMI

Signal of injection molding machine opening mold completion ←→ MCU ←→ Manipulator signal of injection molding machine

Various valve signals

Executive cylinder
The operator operates through the man-machine interface. When the manipulator receives the executable signal from the injection molding machine, the manipulator cuts off the mold-closing signal of the injection molding machine to ensure the safety of the manipulator taking the object. After the removal is completed, the manipulator restores the injection molding machine Actions. The design difficulty of the control system lies in the coordinated working relationship between the manipulator and the injection molding machine. Under the command of the control system, the manipulator completes various actions in accordance with the predetermined working procedures, thereby taking out the injection molded products from the mold and transferring them to the designated location or the next production process. When designing, the control system should be determined according to the performance of the injection molding machine, the operating conditions and requirements of the manipulator, and the shape and weight of the product.
