Ⅰ.Product Overview
The Delta Robot Flexible Feeding System integrates the Delta parallel robot, machine vision, and the flexible vibratory feeder. Designed for high-speed feeding, sorting, positioning, tray loading, and assembly of small components. The vision system identifies the position and orientation of each part, while the robot automatically picks and accurately places the parts at the required position.
It suits for automated feeding of various irregular, thin, fragile, and small workpieces. Its core purpose is to solve the pain points of traditional feeding methods: vibratory feeders can only handle workpieces of a single specification and are prone to jamming; manual feeding is inefficient, has large errors, and is costly.
Ⅱ.Core Structure and Operating Principle
1. Core Structure
The Delta robot feeding system features a compact and modular design. It mainly consists of four key systems that work together to complete the entire automated feeding process, from material identification and positioning to picking and placement.
① Motion Mechanism
The motion mechanism mainly consists of a top stationary platform, 4 arms, parallelogram linkages, and an end moving platform. The servo motors are mounted on the stationary platform and do not move with the arms, which reduces the moving inertia and improves stability and responsiveness during high-speed operation. The parallelogram mechanism also helps maintain the horizontal orientation of the end effector, reducing part displacement or overturning during handling.
②Vision Identification & Positioning System
The vision system is the key sensing module of the feeding system. It mainly consists of camera, lighting system, and vision software. It captures images of randomly positioned parts in real time and identifies their position, orientation, and size. Based on predefined criteria, the system can identify qualified parts and provide their coordinate information to the robot for accurate picking.
③ Flexible Gripping Mechanism
The gripping is responsible for directly picking and handling the parts. Vacuum suction cups are commonly used, together with independent air circuits and check valves. When some suction cups do not contact a part, the system can minimize air leakage and maintain the overall vacuum pressure, improving gripping stability. Customized suction cups or grippers can also be selected according to the shape, material, and surface characteristics of different parts for flexible and damage-free handling.
④Intelligent Control System
The intelligent control system is built around a PLC and servo control system, together with vision and vacuum monitoring modules. After receiving positioning data from the vision system, it controls the robot to perform picking and placement according to the programmed trajectory while monitoring the gripping status in real time. The control system can also communicate with peripheral equipment such as flexible feeders, conveyors, and rotary stations to achieve fully automated feeding operations.
2. Working Principle
The parts are first distributed and separated by the flexible feeder before entering the vision inspection area. The vision system detects the position, orientation, and status of each part and sends the coordinates to the Delta robot. Based on the vision data, the robot quickly performs picking, rotation, and placement to achieve continuous automatic feeding.
