Description

Technical field: [0001] The invention relates to a detection device, in particular to an intelligent online test device for the power characteristics of a carbon dioxide laser and a manufacturing method thereof. It is a device with a high degree of intelligence and real-time online test of the power characteristics of the laser. Background technique: [0002] The laser power is the most important parameter in the laser. The laser output power seriously affects the quality of laser processing. Therefore, if the laser power can be monitored in real time during the processing process, the stability of the laser power can be improved and the accuracy of the laser power can be improved. Has an extremely important role. However, in China, most laser manufacturers and laser equipment application manufacturers do not have laser power characteristic detection devices. The quality of lasers can only be discovered when they are used, which affects the quality and continuous type of laser pr...

AI Technical Summary

Problems solved by technology

However, in China, whether it is a laser manufacturer or a laser equipment application manufacturer, most of them do not have a laser power characteristic detection device. The quality of the laser can only be found when it is used, which affects the quality and continuous type of laser processing. If problems are found during use, it will also cause an increase in manufacturing costs

However, some manufacturers conduct related simple tests according to their own enterprise standards, which do not meet the requirements of industrial application of lasers.

Moreover, a small amount of laser power characteristic test method is also a traditional test method, which often adopts a one-by-one test method, and there is a "queue waiting" time for different parameter tests, which reduces the efficiency of laser power characteristic test

In addition, there are certain assumed differences in the data tested at different time periods, and the measurement precision and accuracy are not high

At the same time, most laser equipment requires continuous operation, and some existing power characteristic test methods require the laser equipment to stop working when testing laser power, which affects the continuity of laser processing
