Description

Technical Field

[0001] The present invention relates to the technical field of laser welding machines, and in particular to a method and system for intelligent maintenance reminder of laser welding machines. Background Art

[0002] In recent years, with the rapid expansion of the laser welding market, more and more laser welding machines have been put into use. However, in order to ensure processing efficiency and cost, most customers will let the laser welding machine work continuously for a long time. Laser welding machines that lack timely maintenance are very prone to failure, resulting in machine shutdown. There are multiple components on the optical welding machine that need regular maintenance, such as axial modules, lasers, water coolers, etc. The laser welding controller system, as the center of the entire laser welding machine, can obtain the use of various accessories on the laser welding, but there is no accurate and timely system reminder, which will lead to the lack of timely maintenance of the equipment, resulting in poor processing results, low efficiency, and even equipment failure, greatly reducing the service life of the equipment. Frequent maintenance will cause the machine to be shut down for too long for maintenance, and the customer's maintenance cost is too high. The current plan is to perform maintenance on the machine at a fixed time. The disadvantage is that the timing of maintenance is inaccurate. For example, when the machine is running at high load for a long time, scheduled maintenance may lead to untimely maintenance and cause equipment damage; if the machine load is small and the continuous working time is short, scheduled maintenance will cause excessive maintenance and increase maintenance costs.
