(3) Statistical function
The statistics of the test data of the whole production line can be divided into monthly statistics and annual statistics: for the monthly statistical data of the products, you can select statistical conditions, such as the month that needs statistics, the number of unqualified, etc., the form of the chart display can be The pass rate is also the daily output; the annual statistics are counted according to the monthly statistics, so each month's data will be counted in the annual statistics table.
Laser vision inspection station application
With the continuous improvement of the automobile manufacturing level, the laser visual inspection station has been gradually applied. FAW Volkswagen Automotive Co., Ltd. has adopted the system for size control from each assembly, and the faulty parts will be discovered, alarmed and put back in time. Repair area. This ensures that each stage assembly is assembled from a substandard assembly of acceptable size. Not only that, because the data is detected and stored in real time, when problems are found, the manufacturing department can quickly find out the problems of the fixtures and adjust them in the shortest time.
In addition, laser vision inspection systems are widely used in welding production, such as door assembly, front end cutting and welding, and the formation of rear taillight positioning holes in the rear of the body.
In the traditional process, the lamp mounting hole is welded by a plurality of stamping parts, and the accumulated error is large and difficult to control, resulting in poor quality and dimensional instability of the rear tail lamp after installation. The laser vision inspection technology is used, and the punching is performed after the welding of the components is completed. By using the laser on-line measurement, the left and right profiles of the rear taillight are formed into a digital mode, and compared with the digital mode already stored in the Controller, The best match size and adjust the robot to complete the punching process.
An example of the application of laser on-line inspection technology in the assembly of the body-in-white door. The robot-controlled pickup and the laser on-line detection system are controlled by the bus to form a closed-loop system. The real-time dynamic measurement of the laser on-line inspection system in the assembly process of the door cover, the measured data and the standard in the processor are real-time. The comparison of digital and analog data gives the deviation between the measured value and the theoretical value, and adjusts the installation position of the picker in real time to achieve the optimal value of the design. At this time, the flatness and clearance of the door and the side wall will reach the maximum. Good value.
Conclusion
The application of advanced laser on-line inspection systems in different fields of automobile manufacturing has changed some traditional processes in automobile manufacturing to some extent, and it has important significance for promoting the development of automobile manufacturing.
