With the further development of fiber-to-the-home, cloud computing, big data applications, 5G and other internet technologies, the demand for optical fibers has increased significantly. Due to objective factors, the optical fiber product has the defects of missing welding, missing welding and the like, the working performance of the optical fiber is influenced, and if the optical fiber part with the missing welding point is directly removed, the waste is caused to a greater extent. In order to improve the quality of the optical fiber product and save the cost, a repair welding machine is needed to perform repair welding on the defect position.
The repair welding machine can instantly (in milliseconds) release welding energy to a certain minimum range (less than one square millimeter) so that a repair material is completely welded on a workpiece. The whole workpiece generates little heat, thereby avoiding the defects of deformation, cracks, color change and the like of the traditional welding, and being particularly suitable for repairing fine workpieces and workpieces which can not be welded at high temperature. However, the conventional repair welding machine is not intelligent enough, and needs to manually observe the change of welding power, align the position to be welded under a microscope according to the change of welding power, and then step on the repair welding machine triggering a single light beam, so as to perform repair welding. The mode depends on manual operation and human eye observation, and has the problems of low efficiency, inaccurate repair welding position, unattractive appearance and the like.
In order to solve the problems, the conventional repair welding machine inputs a specific position to be welded into a control system of the repair welding machine through external equipment before welding is started, and then the repair welding machine automatically adjusts a station, so that a laser head of the repair welding machine is aligned to the position to be welded to start repair welding. Although the scheme converts the manual alignment of the welding position into mechanical alignment, the accuracy of the repair welding position is improved, the specific welding position data still needs manual acquisition and input, and the repair welding efficiency is low; and the welding position data may be affected by position errors during optical fiber fixing, so that the welding position data cannot be correspondingly accurate after being input, and the probability of inaccurate repair welding exists.
