Eliminating Wrong Spot Welding by Robots in Production Line

Abstract

The main objective of our project is to reduce the false seam joints. There are many important issues, such as waiting for a lost robot, checking individual parts, unnecessary manual nutrition and increasing the cycle time of this soldering joint. When the cycle times are getting longer, the company's revenue decreases accordingly. Many large manufacturing companies have discovered this false weld defect at the end of the painting. In other words, in the field of quality, if an error is detected in the material during the inspection, it is completely lost. The content is processed or replayed until the entire row is stopped and the entire row is off. This manufacturer proves a defect in two ways. One is with a laser and another by ultrasound. Test equipment is placed in the mass zone for testing purposes. You can get 99% of the correct output. However, this is not necessary if the error is completely lost in the final stage, if the economic cost of these devices is high and if the skilled worker has to deal with this problem, our project, therefore, will use another device. To avoid this error in the initial phase, we found that the weld at the main point increased due to the poor solution in the drawer. Using simple Plc coding methods, we use light and automation sensors to develop devices that detect seat position changes. We use the Six Sigma method to eliminate this error. It is possible to eliminate the risk of wrong place welding and reduce the output defect by 100%.
