Assembly of terminal blocks with the help of intelligent vision and robotics

With the help of NI Standard, we can quickly assemble the products of a project to shorten the time and reduce costs.

Challenge:

Designing an intelligent robotics system with image processing to assemble different electronic components using short arms.

Approach:

The installation of five Mitsubishi SCARA robots equipped with the NI vision system, which uses Mitsubishi’s Robots Library ImagingLab LabVIEW, and multiple NI IEEE 1394 image receivers with I / O reset, the software with the help of NI LabView and NI Vision Development it is developed.

One assembling and packing line assumes that different types of electrical terminals (about 40 models) are assembled into an intelligent cell that can be divided into six stages. The five Mitsubishi SCARA RP-5AH robots are mounted around a desk, each one designed to perform a specific task that can change the model to model.

Required project specifications:

  • 2500 pp
  • Assemble 40 different items
  • Requires a total of 32 different parts for the assembly of parts

Six cameras installed, each for a robot station plus an additional camera for quality control. Each station is designed to produce a piece based on the type of production. The key to this project is to allow the line operator to handle the robot’s arms.

Configure the visual system and feeder

We know the machine vision sector as the most important part of the project, the visual machine enables robotic cells to detect different parts in random positions, harvest and assemble them according to the type of product with a very high precision to prevent Specific settings have been used for each model, thus reducing the time of stopping piece changes and creating for each model the appropriate classification and storage.

In addition, selecting a feeder system for each robotic station is important to maintain flexible settings. The parts can be placed in random positions on the feeder; therefore, the feeder should be able to move parts forward by moving the vibration and for the sight to prepare the robot to select them.

Each station uses the FlexFactory Anyfeed SX-240 feeder, which can be programmed and managed by LabView based on system information.

When the parts arrive by the feeder, the visual system opens the image to find and remove the piece. The position information of the piece is sent to the robot, and after removing them with a precision of 0.02 mm, they put them in the right place.

Vision systems, robots and feeders, and controls the quality on the parts to be assembled in terms of size and appearance. If they are healthy, they will be added to the terminal assembly, otherwise The product line is deleted.
