An automated production method for insert injection molding, including the following steps: Step 1. A six-axis mechanical arm takes metal inserts: four stations I are set on the carrier plate, and two identical metal inserts are manually placed into the There are two grooves on the carrier plate on the station Ⅰ; then, the carrier plate rotates at a certain angle to reach the designated position, and the grating device Ⅰ above the carrier plate station Ⅰ is used to detect whether the metal insert has arrived and placed properly , if placed correctly, the six-axis robotic arm comes to pick up a pair of metal inserts. The upper and lower sides of the end of the six-axis robotic arm are equipped with grabbing devices. When taking metal inserts, the lower surface of the end of the six-axis robot arm grabs a pair of metal inserts on the carrier plate, and then the six-axis robot arm moves the metal inserts to the insert injection molding machine. Simultaneously, the carrier disc rotates at a certain angle, waiting for the next pair of metal inserts to be manually placed.

Step 2. Injection molding of metal inserts: The end of the six-axis robotic arm is turned 180 degrees, and the free side that has not grasped the metal inserts faces down, and aligns with the two slots on the insert injection molding machine. The injection molded pair of metal inserts is then turned over 180 degrees, and the metal inserts to be injected at the end of the six-axis robotic arm are placed in the slot of the injection molding machine for injection molding. A six-axis robotic arm then moves the pair of metal inserts from the previous injection to the punching mechanism.

Step 3. In the punching mechanism, the four-axis robot arm receives the injected metal insert from the six-axis robot arm, and the four-axis robot arm grabs the injection-molded metal insert on the upper surface of the end of the six-axis robot arm, and then , the six-axis robotic arm returns to the tray picking area of the carrier to grab the next pair of metal inserts.

Step 4. Punching of injection molded products: the four-axis mechanical arm moves, and puts the metal inserts that have been injected into a pair of grooves in the punching mechanism. The punching mechanism detects whether the product is in place through the grating device II. If the product arrives After the corresponding groove position, the punching process begins. This step can effectively cut off the redundant circuits used to connect the metal inserts during the manufacturing process, making them into multiple sets of independent circuits for transmitting different signals. After punching, a four-axis robotic arm grabs the metal insert and sends it to the testing area.

Step 5. Injection molded metal insert test: The four-axis robotic arm puts the punched metal insert into the inspection tray for inspection. The inspection tray has six stations II, and each station II can place a metal insert . Each metal insert has to pass through the high-voltage (1000V) leakage detector and CCD image detector in sequence with the rotation of the detection disc. The metal inserts on station Ⅱ conduct high-voltage leakage and power-off tests, and also conduct surface quality inspections on the metal inserts to determine whether the metal inserts have surface defects, whether the external dimensions meet the standards, and whether there are any defects during the punching process. Excess circuit cut out.

If a metal insert with an abnormal electrical test is detected, the four-axis robotic arm will put the unqualified metal insert into the box on the left side of the lower end of station II. If a product with a bad image is detected, the four-axis robotic arm will Unqualified metal inserts are placed in the box on the right side of the lower end of station II. After that, the four-axis robotic arm returns to the punching area, waiting for the next delivery of products with the six-axis robotic arm.
