Firstly, when molded parts are released onto a conveyor belt or chute. A wrist rotates 90 degree to release parts carefully without scratching them. Molded parts can be removed by utilizing a vacuum unit. The 90 degrees wrist is included as well. An adjustable 4 suction cup end of arm tool is available is an option. Sprues or edge gates can be cut before molded parts are released. The wrist turns 90 degrees when parts are released. Operation can be interlocked to a conveyor by connecting an optional metal connector, enabling molded parts to be stocked. When a defect signal is received, defective parts are released at a separate location from good parts. The customer can specify a special color for the robot and control box. That's the procedure of most universal robot arm for picking and placing.
The timing of the ejector operation and part gripping operation is synchronized, after runners have been extracted, they can detected by a limit switch. When a runner is gripped and the arm ascends, fragments from the molded parts that are adhering to the mold are blown away using air. To prevent deformation of the molded products, a pressure reducing valve is used. If parts are difficult to release from the vacuum cup, air blows through this valve to ensure safe release of the parts. If the robot will interfere with an object such as a rack mold when the mold closes, the robot can be set to stand by at the swing out limit. The robot can use automatic injection signal output from the molding machine as a condition begin extracting. This initiates automatic operation only when parts have been molded. Automatic injection signal the take-out robot arm uses the automatic injection signal input of the molding machine as the condition to begin extracting. Using this signal makes it possible to initiate the extracting operation only when products have actually been molded.
