Case Study | 3D vision-guided large size aluminum profile loading solution
Due to high temperature resistance, corrosion resistance, good heat transfer and electrical conductivity and other characteristics, aluminum profile is selected as the manufacturing material of new energy electric vehicle battery shell. Compared with steel shell, aluminum profile shell is lighter, thinner, and can meet requirement of lightweight and safty the power battery.
This case study will share how an autoparts manufacturer used 3Dvisionto guide a robot to complete the automatic loading of aluminum profiles on the processing line of square battery housings.
Pain Points
§ The workpiece is transported to the loading station by forklift or AGV in the form ofstacking, the aluminum profiles are placedin the black plastic pallet layer by layer , the offset of the workpiece during transportation and the overall placement accuracy of the stacking are not enough for the robot to complete the grasping and loading through the fixed position teaching, so the deviation needsto be corrected by 3Dvision.
workpiece picture
§ A single piece of aluminum profile is about 2meters, and the 3D vision system needs to have a large field of view and depth of field to cover large stacks;
§ The station is set at thefront end of the processing line, close to the workshop door and window, the light and light changes at different times will affect the lighting of thestation, and the light will cause reflection on the surface of some batches of workpieces, which requires 3D visionto have light adaptability and reflective adaptability;
§In order to improve the utilization rate of the entire production line, a variety of workpieces of various sizes are processed at the same station, requiring flexible production.
Solution
After the comprehensive evaluation of the workpiece characteristics, grasping accuracy and working environment, the project selected AT-S1000-01A 3Dvision system to meet theuser's workstation design and production needs of efficient, accurate and stable.
· The 3D camera adopts binocular laser structured light imaging, has good environmental suitability, has the ability to operate under outdoor light, and can stably collect images and generate reliable pointclouds under 100,000Lux.
· The product has a large field of view, large depth of field, can coverlarge-size stacks, and can achieve multi-grab bit coordinate feedback in onescan;
· The accuracy meets the user's accuracy requirements, and the algorithm effectively eliminates distortion to ensure that the edge accuracy and center accuracy of large workpieces are consistent to achieve stable grasping;
· The reflection of the profile surface and the pure black pallet can be effectively recognized, and the empty tray can be quickly judged;
· It can realize the automatic switching and matching of various sizes of incoming materials, distinguish the orientation of workpieces, improve the production flexibility and utilization rate of the station, and meet the flexibility requirements of the order-based production mode;
· The 3D vision system is simple to operate, and through simple training, equipment operators can smoothly introduce new specification workpieces within two hours without mastering complex programming knowledge;
