[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] Injection molding is a process in which plastic material is completely melted by a screw at a certain temperature, injected into a mold cavity under high pressure, and then cooled and solidified to obtain a molded product. When injection molding parts composed of both metal and plastic, the metal components are manually placed one by one into the injection mold. After injection molding, they are removed from the mold and placed in a finished product collection box.

[0004] In traditional injection molding processes, the material handling and unloading processes are all done manually. Therefore, when there are many metal components to be injection molded, the number of times the material handling and unloading actions need to be repeated increases, the labor intensity of workers increases, and the efficiency decreases. At the same time, there are errors in the position of each metal component placed in the mold, and the quality of the injection molded product cannot be effectively guaranteed. Currently, there are relatively few patents for material handling grippers. Therefore, when designing grippers, there is an urgent need for a material handling gripper that can accurately match the mold and has multiple functions. Utility Model Content

[0038] Specifically, refer to the appendix Figure 1 Appendix Figure 2 The first gripper 301 and the second gripper 302 are arranged in a group. The first gripper 301 is symmetrically arranged on both sides of the connecting base 101. The first gripper 301 and the second gripper 302 are arranged perpendicularly. When the first gripper 301 and the second gripper 302 are working, the gripper unit 3 can grip the positioning plate of the material frame.

[0039] Specifically, the length of the positioning post 2 is greater than the lengths of the first gripper 301 and the second gripper 302, as shown in the attached diagram.

[0042] An automated injection molding robot includes the aforementioned feeding gripper, and further includes a dual-worktable switching unit 7, a detection unit 8, a six-axis robot 9, a turntable injection molding machine 10, a material frame 11, and a conveyor belt 12. The dual-worktable switching unit 7 is used for transferring the material frame, the six-axis robot 9 is used for gripping, moving, and transferring the injection molded product from the material frame, the turntable injection molding machine 10 is used for injection molding, the detection unit 8 is used for mold detection, and the conveyor belt 12 is used for conveying the mold. The dual-worktable switching unit 7 includes a manual pin insertion station and a robot gripper material picking station.

[0043] The material frame 11 is provided with a positioning hole 110 and a positioning plate on its upper part.

[0044] The dual-worktable repositioning fixture has two stations: a manual pin-installation station and a robot gripper-grabbing station. After the equipment starts normally, the operator installs the pins at the manual pin-installation station and presses the start button. At this time, the material frame 11 with the pins is transferred to the robot gripper-grabbing station. The empty material frame is simultaneously switched to the robot gripper-grabbing station. After the material frame 11 is in place, the arrival sensor sends a signal to the six-axis robot 9. The six-axis robot 9 drives the grippers to arrive at their positions, and the first gripper 301 and the second gripper 302 on both sides move simultaneously to clamp the material frame 11. Driven by the six-axis robot 9, the material frame 11 is picked up and placed above the mold. After the six-axis robot 9 arrives at its position, it sends a signal to the grippers to release them. After the gripper arrival detection sensor detects that the grippers have released, the two pressing cylinders 601 drive the pressing plates 602 of the material frame 11 to press down simultaneously, pressing the material frame 11 into the mold. The mold is equipped with a material frame detection sensor. After the material frame 11 is detected to be in place, the rotary injection molding machine 10 starts working. After injection molding is completed... The injection turntable rotates, and the injection molded product and material frame 11 rotate to the starting position. The turntable injection molding machine 10 sends an arrival signal to the six-axis robot 9. The six-axis robot 9 moves with the grippers above the mold. After the six-axis robot 9 arrives, it sends a signal to the grippers. The first gripper 301 and the second gripper 302 on both sides move simultaneously to clamp the material frame 11. At the same time, the product pick-up suction cup 401 picks up the injection molded product and judges whether the product has been successfully picked up by the pressure sensor. After the product is successfully picked up, the pressure sensor sends a signal to the robot. The six-axis robot 9 picks up the injection molded product and places it at the detection station. During the robot's movement, the material frame detection sensor detects whether the material frame 11 is in place. After the material frame 11 is in place, the sensor at the manual pin loading station lights up to indicate to the operator that the switching fixture can be started. The empty material frame at the robot gripper picking station is transferred to the manual pin loading station, and the material frame 11 with pins at the manual pin loading station is transferred to the robot gripper picking station. After the six-axis robot 9 arrives at the inspection station, it sends a signal to the material pick-up suction cup 401. The material pick-up suction cup 401 places the injection-molded product onto the inspection station. Then, the six-axis robot 9 drives the gripper to grab a new material frame 11 above the robot gripper material pick-up station and repeats the above actions. The conveyor belt 12 unloads the product into the defective product box or material box according to whether the inspected product is qualified.
