2021 Cognex Product Application Automotive Industry Solution Collection

1. The In-Sight 7905 vision system guides the robot to realize the guiding and grabbing of the cylinder head PRV

Challenge: Conventional vision tools cannot accurately identify workpieces made of transparent plastic, and the vision system has a small installation space on site, and the robot cannot guide the gripping.

The result: The In-Sight 7905 vision system is compact and modular, allowing for customizable site heights to solve space constraints. And the imaging effect is good, accurately identify the front and back sides of the workpiece, the accuracy rate is greatly improved, reaching 99.8%, and the robot is successfully guided to locate and grab.

2. Cognex 3D-A5000 series area scan cameras help FAW-Volkswagen's new energy battery factory robots solve the problem of unstable grasping

Challenge: When the robot grabs the battery shell, it requires a high accuracy of the discharge position of the material truck, and the logistics personnel are time-consuming and laborious when parking the material truck; Each material car is equipped with four layers of shells, the height of each layer is inaccurate, and the limit accuracy of the battery shell is low, which causes the robot to grasp the shell unstable, and the production is prone to failure, affecting the production beat, and causing the production to stop; Due to the poor grasping stability of the manipulator, the robot has been running slowly and needs technicians to accompany the delivery and deal with machine failures, which affects production efficiency and wastes manpower.

Effect: Logistics personnel no longer need to accurately place the material truck in the loading position, which saves the discharge time and improves the work efficiency of logistics personnel; Even if the accuracy of the material car is not high, the robot can grasp stably, ensuring the smooth progress of production; After using Cognex 3D-A5060, the detection accuracy reaches 0.1mm, which exceeds the predetermined index, the robot grabbing is very stable, there is no longer the problem of production line shutdown, and the enterprise no longer needs to arrange manual handling of on-site problems, which saves a lot of manpower and material resources, and greatly improves production efficiency.

3. Cognex 3D vision software: realize the efficient and accurate grasping of the automobile engine block by the robot

Challenge: The manual feeding method affects the production cycle and has potential quality hazards; The vision system should be able to guide the robot to quickly and accurately grasp a variety of workpieces with a program, and meet the angle requirements of three directions with an accuracy of 0.3mm, and also need to overcome the adverse effects of on-site ambient light.

Effect: The automation of the feeding station has been realized, replacing 10 manual laborers, and the yield rate has been improved; The four types of workpieces can be used in one program to guide the robot to grasp quickly with high precision, the actual visual accuracy exceeds expectations, and provides a stable light environment to ensure the detection effect.

4. The Cognex In-Sight 7802 vision system helps Bosch solve the problem of automotive motor winding detection

Challenge: If the camera does not reach the shooting angle of the camera, the fitting detection area will be reduced, which will affect the judgment of the proportion of copper wire extension. The surface pits appear in the hook, which will affect the judgment of the copper wire of the hook; The headline is too short to be judged by the blob width.

Effect: Efficient detection, accurate verification of various winding defects; The operation is simple and fast, the beginners get started quickly, and the product stability is strong; The yield rate has increased to 97%, and the production efficiency and economic benefits have been significantly improved.

5. Cognex In-Sight 9912 vision system helps Sinotrans solve the problem of tire inspection

Challenge: Difficult to identify, small size of the object and wide variety of colors.

Effect: It can detect whether the point is damaged, and distinguish the color type of the point, so that the yield rate can be increased by 20%.

6. Cognex In-Sight vision system helps the automotive electrical box production line to achieve automatic inspection

Challenge: The types of defects are complex and subtle, manual inspection is difficult, labor intensity is high, and manual inspection is prone to quality inspection problems such as wrong installation, multiple installation, and missing installation, which will also lead to the risk of defective parts flowing out, low efficiency and high cost.

Effect: The visual inspection of the product realizes intelligent automation, solves the risk of outflow of defective parts such as wrong installation, multiple installation, and missing installation, greatly improves production efficiency, and eliminates customer quality complaints; The payback period is only 0.13 years, and it can meet the needs of multiple types of workpiece defects at the same time

7. The application of 3D displacement sensor realizes the automatic measurement of the appearance size of the PACK board and solves the problem of product deformation detection

Challenge: The manual sampling method leads to low detection efficiency, and it is difficult to trace the defect problem. Visual products are required not only to have a large field of view, but also to have high precision, and also to achieve accurate image stitching of laser scanning products, and it is difficult to obtain measurement data.

Effect: Realize the automation of inspection, and the efficiency has been greatly improved; The detection accuracy has reached the expectation, meeting the requirements of the product's largest field of view, and solving the problem of image stitching and measurement, and easily customizing the database.
