[0002] refer to Figure 15 During the manufacturing process of automotive connector parts 901, terminals 910 need to be sent to the molding mold of the injection molding machine to be integrally formed with the product housing 920 in the mold. At this time, sprue material 902 is connected between the two connector parts 901 to form the injection molded finished product 900. Optical inspection equipment is needed to detect whether the two connector parts 901 in the injection molded finished product 900 are good products. If they are good products, the two connector parts 901 need to be knocked off from both ends of the sprue material 902 and the good connector parts 901 need to be collected. At the same time, the defective injection molded finished product 900 and sprue material 902 need to be collected in designated locations. Currently, all of the above processes require manual processing, resulting in low production efficiency. Utility Model Content

[0053] When this utility model is in operation, the terminal 910 is output from the vibrating plate 21 to the terminal conveying groove 221 of the conveying support plate 22 and moves vibratingly towards the output end of the terminal conveying groove 221. When the terminal 910 moves to the output end of the terminal conveying groove 221, the clamp 241 of the parallel air clamp 24 moves horizontally to directly above the terminal 910 to prevent the terminal 910 from derailing. At this time, the terminal insertion hole 311 is directly opposite the terminal 910. Then, the terminal 910 continues to move horizontally and is inserted into the terminal insertion hole 311. After the terminal 910 is inserted into place, the position sensor 40 senses the terminal 910 and transmits the signal to the control system. The control system controls the clamp 24 of the parallel air clamp 24 to retract inward to the outside of the terminal conveying groove 221. Then, the control system controls the drive cylinder 323 to rotate the roller 31 upward 90 degrees outward, waiting for the robot to take away the terminal 910. The clamp 24 of the parallel air clamp 24 retracts inward to the outside of the terminal conveying groove 221, so that when the roller 31 rotates upward and flips outward, the clamp 241 of the parallel air clamp 24 is prevented from jamming the terminal 910.The feeding robot 230 inserts the terminal 910 into the insertion hole 621. Then, the terminal fixture 6 moves forward with the moving module 5 to the front of the housing 100 and is positioned to the right by the two mold guide pillars 64 to align with the product mold in the injection molding machine. After that, the terminal 910 and the product housing 920 are integrally formed into connector accessories 901. The two connector accessories 901 are connected by sprue material 902 to form the injection molded product 900. Then, the moving module 5 drives the terminal fixture 6 to detach from the product mold, so that the injection molded product 900 is taken out with it. Then, the moving module 5 drives the terminal fixture 6 to retract back into the housing 100. Then, the ejector pin 634 of the terminal ejection assembly 63 pushes the terminal 910 out to the right. At the same time, the feeding robot 230 grabs the detached injection molded product 900 and sends it to the placement cavity 421. The linear motion module 410 moves the injection molded product 900 forward. When it passes the two product optical inspection devices 700, the two product optical inspection devices 700 respectively optically inspect both sides of the injection molded product 900 to obtain image data from both sides of the injection molded product 900, thereby determining whether the two connector accessories 901 in the injection molded product 900 are good products. If they are good products, the injection molded product 900... As the linear motion module 410 moves to below the detection gripper 753, the detection gripper 753 moves down and grabs the injection-molded product 900, sending it into the impact space 801. It then swings back and forth with the lateral motion module 751, causing the two connector parts 901 of the injection-molded product 900 to impact the first impact arm 810, and causing the two ends of the sprue 902 to impact the two second impact arms 820. This causes the two connector parts 901 to detach from the ends of the sprue 902 and fall through the center hole of the impact mounting frame 830 onto the good product conveyor belt 550. The sprue 902 is conveyed to the designated storage location for good products, while the removed sprue 902 moves with the detection gripper 753 to the sliding opening 571. The detection gripper 753 releases, allowing the sprue 902 to slide down the sprue slide 570 to the designated storage location. If it is a defective product, the injection molded product 900 moves with the linear motion module 410 to below the detection gripper 753. The detection gripper 753 moves down and grabs the injection molded product 900, moving it to the opening of the defective product receiving basin 560. The detection gripper 753 releases, allowing the defective injection molded product 900 to fall into the defective product receiving basin 560. The entire process is automatically controlled by the control system.
