DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a single-swing air-cooled handheld welding head, such as Figure 1-Figure 3 As shown, it includes a first shell 10 and a second shell 11, a collimating lens module 101 is installed inside the first shell 10, a QBH connector 1 is installed on the outer end of the first shell 10, a focusing lens module 3 is installed inside the second shell 11, an X-axis swing motor reflecting lens module 2 is installed on one side of the second shell 11, a protective lens module 7 is installed on one side of the focusing lens module 3, an adjusting focus point assembly 8 is installed on the outer side of the protective lens module 7, a copper nozzle 9 is installed on the outer side of the adjusting focus point assembly 8, the adjusting focus point assembly 8 is an existing conventional technical content, and focusing operation is performed by adjusting the focusing point assembly 8, which is a conventional structure of an existing welding head and will not be described in detail here.

[0022] In this embodiment, one end of the first housing 10 is connected to a gas interface 6 for easy introduction of gas.

[0023] Specifically, a light directing channel 12 and a light focusing channel 13 are arranged between the collimating lens module 101 and the focusing lens module 3. One end of the light directing channel 12 is connected to the collimating lens module 101, and the other end of the light directing channel 12 is connected to one end of the light focusing channel 13, and the other end of the light focusing channel 13 is connected to the focusing lens module 3.

[0024] Furthermore, the X-axis swing motor reflective lens module 2 includes a swing motor and a reflective lens. The output shaft of the swing motor is connected to the reflective lens. The reflective lens is located at the junction of the light directing channel 12 and the light focusing channel 13 to facilitate pipeline transmission.

[0025] Furthermore, a switch button 5 is installed on one side outer wall of the second housing 11 to facilitate controlling the emission of the laser.

[0026] Furthermore, the copper nozzle 9 is a circular or square structure to adapt to welding operations in various scenarios.

[0027] Furthermore, an air cooling channel is provided inside the first shell 10, one end of the air cooling channel is connected to the gas interface, and the other end of the air cooling channel is connected to the inside of the second shell 11, so as to facilitate the passage of gas for air cooling.

[0028] Furthermore, an intelligent monitoring display light 4 is provided on one side outer wall of the second shell 11, and an intelligent monitoring module is installed on the inner side of the second shell 11. The intelligent monitoring module includes a contamination detector for detecting the lens contamination value and feeding back the data to the intelligent monitoring display light 4 for further reminders and alarms.

[0029] When the single-swing air-cooled handheld welding head of the utility model is used, first, the laser enters the welding head through the QBH joint 1, and then passes through the collimating lens module 101, which adjusts the laser into parallel light. These parallel light rays are then transmitted to the X-axis swing motor reflective lens module 2 through the light directing channel 12. Here, the swing motor can drive the reflective lens to make precise angle adjustments, thereby realizing the swing function of the welding head, which is very useful when welding curves or complex patterns.

[0030] The reflected light enters the light focusing channel 13, and finally focuses the laser to a very small point through the focusing lens module 3 to provide sufficient energy density for welding. At the same time, the protective lens module 7 is used to protect the focusing lens from damage by spatter that may be generated during the welding process.

[0031] During welding, the focus adjustment component 8 allows the user to fine-tune the focus position as needed to ensure welding quality. The copper nozzle 9 serves as an outlet of the welding head, and its shape (round or square) can be selected according to specific welding requirements.

[0032] In addition, the air cooling function of the welding head is realized through the air cooling channel inside the first shell 10. When the gas is introduced through the gas interface 6, it will flow through the air cooling channel to cool the inside of the welding head, thereby effectively reducing the heat generated during the welding process and ensuring the stable operation of the welding head.

[0033] Importantly, the intelligent monitoring module plays a key role in the welding process. The contamination detector in it continuously monitors the contamination level of the lens. Once it detects that the lens contamination exceeds the safety threshold, the intelligent monitoring display light 4 will immediately light up to warn the user. This intelligent monitoring function greatly reduces the risk of welding quality problems and equipment damage caused by lens contamination.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
