Minimize the time required for visual inspection of mounting substrates

1. Improve inspection output by reproducing the knowhow of skilled inspectors

When performing an automated visual inspection of multiple inspection points, the inspection path and focus of the inspection you choose can have a significant impact on inspection efficiency. It is essential to reproduce the professional visual inspection knowhow of a skilled inspector.

 

2. Transform the inspection knowhow into explicit knowledge to realize the start-up of equipment and devices

There is a shortage of qualified inspectors who can set the shortest inspection path. In order to automate inspections at manufacturing sites where equipment and installations are frequently commissioned, it is necessary to translate specialized inspection knowhow into explicit knowledge so that everyone can set the shortest path.

 

Solution

■ Combination of vision sensor and motion to achieve optimal operation

Automatically generate ideal inspection paths and operation trajectories.

For efficiency, visual inspection paths are often drawn by looking for the shortest path that covers all checkpoints. Omron's solution is based on this. The solution checks not only the inspection path of the vision sensor, but also its trajectory, so that the path with the shortest moving time can be found. Optimize the motion control of the vision sensor by finely balancing path finding and manipulation trajectories, minimizing inspection time.

 

■ Automatically calculates the ideal inspection path

The ideal inspection path is automatically calculated based on the entered inspection position

In the past, finding the ideal inspection path required trial and error. Workers need to enter measurement locations, set up multiple paths, then measure the inspection time for each path, and finally the experienced engineer decides which path to use. The technology we have developed automatically calculates the inspection path based on the input inspection position, reducing the recipe setup effort (reference value) by 75% and speeding up equipment commissioning.

 

■ Realize high-speed, uninterrupted multi-point inspection

Automatically generate inspection actions to minimize visual inspection time

The sensor moves on the shortest path between checkpoints, requiring an abrupt change of direction at each checkpoint, with a small stop time, which can slow down the movement. Omron's solution enables the sensor to move without slowing down by automatically generating an inspection path that curves the trajectory, minimizing the travel time and reducing the inspection time by 60% (reference value).
