[0040] The specific working principle is as follows: referring to the drawings Figure 12As shown, the nuts are placed on two different nut carrying jigs according to the arrangement of the pressing nut insertion mechanism 23 of the rear mold nut insertion mechanism 2 and the arrangement of the front mold nut insertion mechanism 3, respectively, and the arrangement of the nuts on the two nut carrying jigs corresponds to the arrangement of the pressing nut insertion mechanism 23 and the front mold nut insertion mechanism 3, respectively, facilitating grabbing. This corresponding layout of the nut placement carrying jig designed according to the position of the plastic nut is widely used in the industry, facilitating the operator to place it in the corresponding position in the injection cavity of the injection mold according to the position of the nut, ensuring the accuracy of the nut placement position, which does not need to be described in detail in this application. The technology protected in this application is a insert nut insertion and material taking device capable of automatically inserting nuts and taking plastic product 5, which is installed on a robot arm through a flange plate 11. The robot arm can drive the insert nut insertion and material taking device to change different angles to adapt to the insertion of nuts and the taking of plastic product 5. During work, according to the requirements, the robot arm rotates the base 1. When it is needed to insert nuts on the rear mold of the injection mold, the robot arm drives the rear mold nut insertion mechanism 2 to move above the corresponding nut carrying jig, so that the position of the nut sleeve 232 on the pressing nut insertion mechanism 23 corresponds to the position of the nut on the nut carrying jig. Then the robot arm drives the rear mold nut insertion mechanism 2 to descend, so that the nut sleeve 232 is placed outside the corresponding nut. After the nut enters the sleeve hole 2321 of the nut sleeve 232, the position sensor 2323 senses the object entering and transmits a signal to the external electric control cabinet. The electric control cabinet controls the positioning cylinder 2322 to open, and the positioning cylinder 2322 drives its piston rod to extend, so that the nut is clamped in the nut sleeve 232 by the end of the piston rod. Then the robot arm controls the rear mold nut insertion mechanism 2 to move above the rear mold injection cavity, and places the nut in the sleeve hole 2321 in the specified position in the rear mold injection cavity after aligning. When the nut is placed, the positioning cylinder 2322 drives its piston rod to retreat and release the nut in the sleeve hole 2321. The nut falls into the corresponding position of the rear mold injection cavity. Then the ejector cylinder 5 drives the connecting seat 233 to descend, and the connecting seat 233 drives the pressure rod 234 connected thereto to descend synchronously. The end of the pressure rod 234 presses the nut at the bottom into the corresponding position of the rear mold injection cavity. After pressing, the pressure rod 234 resets upward, and the robot arm drives the insert nut insertion and material taking device to return to the nut carrying jig to grab the next group of nuts.When inserting a nut into the injection cavity of the front mold, the robotic arm controls the insert nut insertion and picking device to rotate, so that the grippers 331 on the front mold nut insertion mechanism 3 face downwards, ensuring that the clamping grooves 332 on the grippers 331 face downwards. The robotic arm controls the insert nut insertion and picking device to move above the support fixture for the nut in the front mold, and controls the insert nut insertion and picking device to descend. At the same time, the dual-axis dual-rod cylinder 31 drives the end plate 322 to descend, and the end plate 322 drives the finger cylinder 33 to descend. When the two symmetrical grippers 331 are engaged with the outside of the nut on the support fixture, the robotic arm controls the insert nut insertion and picking device to rise, so that... The nut detaches from the corresponding support fixture and moves to the injection cavity of the front mold. The robot arm then controls the insert nut insertion and picking device to descend, causing the nut gripped by the gripper 331 to reach the designated position and gradually release the nut. Simultaneously, the ejector cylinder 34 drives the ejector pin 342 to extend through its piston rod 241, pushing the nut in the corresponding clamping groove 332 into the designated position in the injection cavity of the front mold. After the nut is inserted, the dual-axis dual-rod cylinder 31 controls the end plate 322 to reset. The end plate 322 drives the finger cylinder 33 to reset synchronously, separating from the front mold. After separation, the robot arm controls the insert nut insertion and picking device to move to the nut support fixture, ready for the next round of nut gripping. The nut is then unloaded from the injection molding machine through the insert nut insertion and picking device. Figure 13 When the plastic part product 5 is being processed, the robot arm controls the insert nut insertion and material handling device to rotate, so that the plastic part removal mechanism 4 corresponds to the injection molded product 5 in the mold cavity after mold opening. Then, the robot arm controls the insert nut insertion and material handling device to gradually approach the injection molded product 5, so that the two sets of material handling cylinders 43 and chucks 44 enter the central opening of the plastic part product 5. At the same time, the vacuum suction cup 42 approaches the contour end face of the plastic part product 5, contacts and adsorbs the plastic part product 5. Simultaneously, the material handling cylinder 43 drives the chucks 44 to open outward, so that the end of the chucks 44 is stuck on the inner side wall of the central opening of the plastic part product 5. Figure 12 As shown, the two sets of clamps 44 hold the plastic product 5 and work with the vacuum suction cup 43 to ensure the stability of the gripping of the plastic product 5. The plastic product 5 can be taken out of the mold cavity and placed in the set placement area.

[0041] This insert nut insertion and picking device, used in conjunction with a robotic arm, allows for the setting of nut insertion mechanisms at corresponding positions according to the nut insertion layout. This enables batch picking and insertion of nuts, improving the insertion efficiency of nuts in the injection mold cavity. Different functional nut insertion mechanisms can be used to coordinate nut picking and insertion based on the nut insertion position, offering flexible operation. Through adsorption and clamping, it enables automatic unloading of plastic parts 5, preventing damage and ensuring product quality. This improves production efficiency, saves labor, and reduces production costs.

[0042] It should be emphasized that the above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
