AI Technical Summary

Technical Problem

Existing material boxes cannot provide a stable and consistent background and material posture for visual recognition systems, making it difficult for visual systems to quickly and accurately locate part feature points, resulting in unstable robot grasping. Furthermore, developing dedicated material boxes for each model is costly and makes warehouse management difficult.

Method used

An automatic assembly and positioning frame for excavator stick components has been designed, including a shaft seat positioning frame, a side plate positioning frame, and a feed component positioning frame. It adopts replaceable shaft seat assembly positioning pins, position-adjustable positioning pins, and multiple positioning mechanisms to achieve neat placement of components and high repeatability positioning accuracy, and is suitable for precise positioning of multiple models of components.

Benefits of technology

It achieves a stable environment for the visual recognition system, improves the accuracy of robot grasping and the stability of the production process, reduces tooling costs and storage space requirements, and has a high degree of flexibility in changing models.

Abstract

This invention discloses an automatic assembly and positioning frame and changeover method for excavator boom components, belonging to the field of excavator structural component manufacturing automation technology. The positioning frame includes a frame body, a shaft seat positioning frame, a side plate positioning frame, and a blanking component positioning frame. The shaft seat positioning frame is equipped with replaceable shaft hole positioning pins for precise positioning of the shaft seat assembly; the side plate positioning frame is equipped with multiple position-adjustable positioning pins for contour-guided limiting of the side plate assembly; the blanking component positioning frame includes a gravity self-positioning mechanism with an inclined positioning surface, a movable positioning mechanism that can move relative to the frame body, and a support tube positioning mechanism with multiple tube seats, respectively used for positioning different plates and tubes. This invention provides a regular and highly repeatable material posture for the automatic assembly process, solving the problems of difficult visual recognition and unstable robot grasping, while reducing tooling costs and storage space, achieving highly flexible changeover and efficient production.
