Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, and the attached drawing in describing is that this is practical
Novel some embodiments to those skilled in the art without creative efforts, can be with
Other accompanying drawings can also be obtained according to these attached drawings.
Fig. 1 is the coaxial temperature feedback welding system example structure schematic diagram of multi-pass.
Below with reference to embodiment, and referring to attached drawing, the realization of the utility model aim, functional characteristics and advantage are made into one
Walk explanation.
Specific embodiment
In order to keep the purposes, technical schemes and advantages of utility model clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
Applying example is utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
It is practical new to belong to this for those of ordinary skill's every other embodiment obtained without making creative work
The range of type protection.
As shown in Figure 1, the utility model proposes a kind of coaxial temperature feedback welding system embodiments of multi-pass.
The coaxial temperature feedback welding system of the multi-pass, including acquiring the camera 4 of weld point image, generating the laser of laser
1, laser is transferred to the coupling camera lens 2 of galvanometer 3 and can quickly changes the galvanometer that laser direction makes laser irradiation in bond pad locations
3, the temperature prover 5 of laser irradiation weld point temperature is acquired, and is swashed according to control 5 input temp of temperature prover control output
