The Vision Guided Robot Reduces the Production Cost of Components and Improves the Product Quality

Challenge: implement the picking and placing process, and carry out the transmission and quality control of raw materials and finished components on the production line at the same time.

Solution: KWD will deploy the solution by combining Cognex's intelligent 3D locate image processing software, KUKA's modern robot and the precision machine manufactured by w-plan.

Advantages: compared with the manually controlled inspection process, the product quality is greatly improved. The quality is significantly improved and the scrap rate is significantly reduced, which is conducive to improving the profitability and long-term competitiveness of the company.

Robots move between steel plate components with extremely fast speed and almost playful ease. The welding system of KWD automobiltechnik GmbH, a subsidiary of schnellecke Group AG & Co.KG group in Wolfsburg, Germany, is making a new breakthrough in component production. The robot checks, picks up and places the steel plate at the welding station, and then picks up and places it again for additional testing. The precision machine made by w-plan, combined with connex 3D image processing software and KUKA's modern robot, solves this application of KWD. The precision machine made by w-plan, combined with connex 3D image processing software and KUKA's modern robot, solves this application of KWD. This visually guided picking and placing process performs the transmission and quality control of raw materials and finished components on the production line at the same time. Cognex has proven to be an ideal partner because of the unparalleled excellence of its 3D locate software in the industry. The 3D vision system reliably and repeatedly determines the component position, then detects possible defects in the side plate of the supply rack, and forwards the data to the robot controller.

The robot controller uses the position information of the element to adjust the movement of the gripper in real time according to the direction of the element. As a result, the product quality is greatly improved compared with manual component inspection and positioning. Now, the workload of machine operators is mainly focused on the smooth control of the system, rather than the correct loading and unloading of components.

Precise synchronization

The application of 3D locate software in the automotive industry has been very successful because it handles difficult 3D problems in a step-by-step manner to ensure that customers seize every chance of success. In KWD, the whole production and quality management process of automobile side plates are closely monitored by 3D vision system. According to the different requirements of the operation process, a single or stereo camera is used to record the relevant image area. Cognex 3D locate software provides 3D position data in real time. The intelligent vision system uses patmax? From Cognex's comprehensive visual tool library? Geometric pattern matching tools and different 2D tools. 3D locate software addresses all three aspects of 3D calibration. It directly supports internal calibration and can estimate the parameters of camera sensors and lenses. In addition, it can also handle external calibration, which refers to the position of the calibration camera, whether it is installed on the robot end effector or fixed at a certain position of the robot unit. Finally, it also supports hand eye calibration, which refers to how the user converts the visual results into the robot mobile coordinate system.

In the first operation, a robot positions itself with the gripper and the integrated vision system in front of the component library, in which small components are arranged horizontally on the conveyor. It measures the position of the elements and grabs each element in the correct position. The clamping action is completed in two steps. First, it passes through the vacuum suction element, and then the bolt pin is transferred to the appropriate position and the steel plate is fixed. At the same time, the second robot positions itself with the double-sided clamping system in front of the conveyor and the integrated 3D vision technology system, so that it can locate the large components placed on the vertical conveyor.

The second robot checks the position of the transmission locking assembly and the measuring element and picks up the element in the correct position. Then, the two robots move to the loading station, a turntable, and place the components in the correct position in logical order.

Comprehensive traceability and quality verification

After the spot welding robot completes the welding process, the first and second robots will perform optical spot welding inspection. The inspection content includes the quantity and position accuracy of spot welding. The 3D vision system checks whether the weld is placed in a predefined area. The system will check whether the root of the welding point is correct based on the welding control parameters. The data obtained from the test will be archived and the image will be assigned to the associated parameters. In this way, KWD automobiltechnik has achieved comprehensive traceability and quality verification of reliable records.

To detect the component position, the 3D vision system must position itself with the protruding structure of the sheet metal

In the final working procedure, the second robot removes the finished welded components and places them on the finished component conveyor. If the finished components stacked on the conveyor reach the required quantity, the signal will be sent to the conveyor Logistics Department, which will collect the full conveyor and provide a new empty conveyor.

Comprehensive inspection and satisfaction

In addition to product control, the new system will also provide an important service through Cognex 3D locate, which is the inspection of the predefined area of the system. In addition to the product itself, the 3D vision system will also check some starting and ending positions, such as the tensioning rod of the welding station. In addition, it will inspect the transfer claws of the container to confirm whether they are open or closed. Even under full load, the system can achieve significant efficiency improvement.

In the implementation of 3D vision system, one of the biggest challenges is the light source. The various components of the side plate have no definite position on the conveyor frame, and they may twist or tilt in some areas. This leads to the changing reflection behavior of automotive sheet metal and bare metal. The solution is to construct an enclosure with a white interior wall through which white light is evenly dispersed on the metal elements and the maximum possible incident angle is achieved.

After nine months of development and commissioning, the new plant is running at full speed on the basis of three shifts. However, KWD automobiltechnik is already considering taking further measures. In future systems, the 3D vision system will promote a significant reduction in the number of initiating stations. This will improve cost-effectiveness and minimize potential sources of error.
