Industrial intelligent production line / ROBOT VISION SYSTEM

We have embedded the robot vision system in the automation application to improve the industrial intelligence, and has been applied in the robot 2D vision, 3d vision, laser orientation guidance vision and so on in the automobile industry.

ROBOT VISION SYSTEM-CASE STUDY OF 3D Vision Application

1. Introduction (industry background)

As customers demand higher and higher automobile quality and customization, the automobile manufacturing industry is trying hard to find new production models and technologies to realize more flexible and intelligent production process to upgrade the production line For the robot's front-end incoming material positioning put forward a higher flexible requirements, we hope that the robot can quickly and accurately identify the situation of random incoming material.

Solushin integrates the ALSONTECH-AT-S1000 series 3D vision positioning system with industrial robots to form a flexible upgrade solution for multi-variety, small and medium-volume Parts Processing It changes the original manual processing mode of single machine tool and makes the automatic flexible production possible.

2. PROJECT BACKGROUND

A well-known auto parts factory, products for a variety of specifications of the gearbox Shell. In the newly-built intelligent factory, it is necessary to realize the unmanned production as far as possible, using AGV and robot to realize the workpiece transportation and automatic loading.

3. Problems and pain points that need to be addressed

1. The precision of AGV is not high, if the positioning fixture is designed on it, it will cause the robot can not place and grasp accurately when it is loading and unloading. Can only use pallets to hold the workpiece.

2. Because the position of the workpiece on the pallet is more random, it needs the visual assistant robot to locate and grasp.

3. Because 2D vision can not get depth information, the tray has random deformation, the 2.5 d vision is not flexible enough, and the grasping in the field is unstable, so other solutions are urgently needed.

4. Our Solution

Considering the site layout, the AT-S1000-04A is installed at the end of the manipulator to avoid interference between the camera mounting bracket and the robot or AGV. PRODUCT CONFIGURATION: Vision Range set 600500200, positioning accuracy 1 mm, positioning beat 6 s, line length 29.3 meters.

Program advantages (generally one-to-one correspondence with problems and pain points)

1. With the rapid modeling function, a new model can be imported in 15 minutes without the need to redesign the fixture and robot teaching

2. High degree of flexibility: AGV does not need to be accurate, the position of the workpiece is more random, the tray deformation has no effect.

3. The linear laser scanning system has good adaptability to illumination and workpiece reflection.

4. Equipped with professional extension cable, ensure high-quality image data in 25 meters long distance stable transmission.

5. Customer Expectations

Flexible visual localization, in any case can accurately locate the target workpiece.

6. Customer Revenue

1. The positioning problem, which has been perplexed for a long time, has been solved, the project has been implemented smoothly, and a large number of construction costs have been saved.

2. The Flexibility of 3D vision makes the complexity and difficulty of the whole technical scheme greatly reduced.

3. Visual System Support Remote Assistance, easy to follow up maintenance.

4. The introduction of subsequent new workpiece production is very convenient, reduce the cost of introduction.
