Description

technical field [0001] The invention relates to the technical field of automatic coupling and packaging, in particular to a high-power laser automatic coupling device and a coupling method. Background technique [0002] With the wide application of products such as laser cutting and high-speed optical modules, high-power lasers have been greatly developed. Traditional high-power lasers mostly use manual coupling. The coupling of multiple current points often takes a lot of time and labor intensity, and it is difficult to guarantee the yield of coupling. Secondly, when a high-power laser is coupled, if there is an error in the position of the fiber, the fiber is very easy to burn. Therefore, in the manual coupling method, when the position of the fiber is not controlled accurately, the proportion of fiber damage is relatively large. [0003] Some existing laser coupling devices on the market still have some disadvantages. First, the degree of automation is low, the structure...

[0003] Some existing laser coupling devices on the market still have some disadvantages. First, the degree of automation is low, the structure is complex, the stability is low, and the later maintenance is frequent. Secondly, manual coupling, manual welding, and manual clamping of products are required, and the operation is complicated, resulting in long coupling time. , the processing efficiency is low, resulting in an increase in the production cost of the enterprise
