All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without inventive step, are within the scope of the present invention.

The parameter visualization handheld laser welding gun and the assembly method of the preferred embodiment of the invention, as shown in fig. 1-5, comprise a gun head 1, a handheld part 2 and a display assembly 3; set up the incident light passageway 4 that supplies laser to pass through in the handheld portion 2, set up in the rifle head 1 with incident light passageway 4 complex emergent light passageway 5, the one end that deviates from its laser outgoing on the rifle head 1 is equipped with installation position 6 of installation display module 3, set up trough 7 in the handheld portion 2, trough 7 and installation position 6 intercommunication, through setting up display module 3 alright real-time grasp processing parameter and the correspondence of the actual welding condition on the rifle head 1 of welding rifle.

In the hand-held laser welding industry at present, no matter which hand-held laser welding gun only has a simple welding function, and because a certain distance exists between a processing station and a control console, before welding, the processing parameters need to be preset on the control console, and then a worker walks to the processing station to start the welding gun for welding, but the welding parameters cannot be observed in real time during the welding process, if the parameters are shaken or deviated at the moment, workers cannot find the parameters in time, so that the welding result deviates from the original preset expectation, even a serious person cannot find the problems after welding a plurality of batches of products, and further irrecoverable loss is caused, and after the operator adjusts the parameters and then walks to the welding station for work, the operator needs to go back to the console for observation and adjustment when needing to know whether the parameters change or needing to adjust the parameter change in the process.

In addition, means such as arranging a display device beside a processing station or increasing real-time communication between two persons by hands can be adopted in the industry, but the methods have the defects that the display device can hinder the convenience of processing, the production cost can be greatly increased, the production and the processing are extremely inconvenient, so the industry is not basically adopted, besides the schemes, the display is integrated on a welding gun, but the scheme has the defects of difficulty and heaviness due to various problems, the problems not only need to consider the size problem of the display, but also need to consider the influence of an electrostatic field and high temperature generated by a high-energy laser assembly on the display, the high temperature is blocked, electric shock is also needed to be prevented, the miniaturization layout of the whole device is convenient to hold, various technical problems cause the difficulty and heaviness in real implementation, the domestic and foreign fields are in the technical blank stage, and compared with the traditional handheld laser welding equipment, in the scheme provided by the invention, an operator does not need to run back and forth between the control host and the welding station, the display assembly 3 is encapsulated in the protective cover, and then the protective cover is fixed on the gun head 1, so that when the operator performs welding, the operator can intuitively master the matching of the welding parameters and the actual welding conditions in real time, and the unnecessary loss caused by parameter deviation is avoided.
