Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an automated feeding device for an injection molding machine. Background Technology

[0002] With the upgrading of plastic components in 3C consumer electronics, conventional injection molded parts can no longer meet process requirements to enhance product structural strength. As customer product processes upgrade, auxiliary structures such as iron and aluminum-magnesium components are added to the plastic component structure for injection molding. Initial verification was conducted manually. However, since the injection mold needs to be heated, manual placement poses safety hazards and is prone to abnormalities such as misalignment, detachment, and material mixing, and also increases the risk of plastic particle carbonization. In the intermediate stage, semi-automatic production verification was adopted with manual assistance and robots. Due to the instability of manual operation, product quality and molding cycle could not meet process control requirements, and hidden costs such as labor, machinery, and materials were increased.

The control unit compares the image information with the preset part graphic, and then controls the X-axis mechanism 8, Y-axis mechanism 7 and Z-axis mechanism 6 to move the suction cup assembly to the position of the part to be grasped and grasp the part. Then rotate and adjust the direction of the part to make the direction of the part consistent with the preset part direction, and transfer the part to the secondary positioning platform 4. Finally, the robot arm transfers the part on the secondary positioning platform 4 to the injection molding machine.

[0058] In summary, this feeding equipment can improve production efficiency, reduce labor input, and enhance safety performance.
