[0053] Further, please refer to Figure 5 As shown, the direction of the diagonal flat row of openings 36 corresponds to the air-permeable barrier net 43 on the two-way airflow channel 42, and the direction of the diagonal flat row of openings 37 corresponds to the air-permeable barrier net 43 on the air storage box 47.

[0059] Embodiment 3

[0060] Please refer to Figure 12 and Figure 13 , flat wind assembly 5 includes a welding interface 13 and welding interface 13 left and right side wall on the flow port 51, one of the flow port 51 and the air outlet of the wind disc two 52 is connected, the wind disc two 52 and the air outlet of the air source device two 53 is connected, the other flow port 51 and the one end of the air guide inclined pipe 54 is connected, the other end of the air guide inclined pipe 54 penetrates the top of the splicing table 12 and extends to the outside of the inclined setting.

[0061] In this embodiment, please refer to Figure 12 and Figure 13 , by setting the flat wind assembly 5, flat wind assembly 5 is a structure for preheating the positive and negative welding position of the horizontal frame material, first, its preheating treatment and the diagonal preheating method is slightly different, by using both sides of the flow port 51 to form a parallel convection channel, the air source device two 53 and the wind disc two 52 provide heat flow (the structure of the wind disc two and the wind disc one is the same) for one of the flow port 51, the flow port 51 on one side is parallel to the corresponding flow port 51 on the other side, in the process of transmission, the back of the parallel horizontal frame material welding position is preheated, and the heat flow transmitted to the other side of the flow port 51 is preheated to the front of the corresponding front horizontal frame material welding position through the connected air guide inclined pipe 54, thereby completing the front and back preheating treatment of the horizontal frame material welding position, facilitating subsequent welding process.

[0062] Further, please refer to Figure 1 , Figure 14 and Figure 15 , the descaling assembly 6 includes a mounting ring 61 fixedly connected to the laser welding head 17, an outer sleeve 62 is mounted on the outside of the mounting ring 61, an inner column 63 is slidably connected in the outer sleeve 62, a scraping plate 64 is fixedly installed at the bottom end of the inner column 63, and the top end of the inner column 63 is connected with the top wall of the outer sleeve 62 through the spring 65.

[0063] By setting the deburring assembly 6, the laser welding head 17 is moved to the welding point by the mechanical arm 2 to carry out diagonal welding (the preheating structure is in a stopped state during welding), and the diagonal position is in a local preheating state during welding. The diagonal part of the frame material is also in a heat-weak state due to preheating. When the laser welding head 17 starts to descend to reach the diagonal welding point, the inner column 63 in the outer sleeve 62 on which the mounting ring 61 is installed is in a pressing state at the top of the frame material at the diagonal welding point. The spring 65 is used to make the bottom of the inner column 63 connected to the skimmer 64 tightly adhere to the top of the frame material. Then, when the laser welding head 17 carries out welding operation, the inner column 63 moves synchronously (the welding method of the diagonal welding is laser welding from inside to outside). The burrs of the diagonal part are adjusted in the same direction by the skimmer 64 connected to the lower part, and the surface burrs can also be removed. Then, welding is carried out at each welding point in turn, and the transverse welding part is also the same principle, so as to eliminate the factors affecting the welding quality of the front and rear butt joint positions, and the welding quality of the front and rear surfaces is improved.

[0064] Further, please refer to Figure 7 and Figure 8 The inner end of the two-way air flow channel 42 is also rotatably connected to a refrigeration column 45, and the middle part of the refrigeration column 45 is equidistantly provided with a refrigeration fin 46. The outer end surface of the refrigeration fin 46 is attached to a heat insulation film. The heat cycle system combining the two-way air flow channel 42 and the inclined air outlet 44 is used to accelerate the preheating process and improve the preheating efficiency. After welding is completed, normal temperature air flow is supplied by the inclined air flow assembly 3. In the process of blowing the welding area, the air flow can effectively drive and remove the debris generated in the welding process (the debris that cannot fall off when the supporting plate 7 is turned over). The debris is then effectively collected through the air-permeable barrier net 43. At the same time, the normal temperature air flow entering the two-way air flow channel 42 drives the refrigeration column 45 to rotate, and the refrigeration fin 46 installed thereon starts to release cold air (the refrigeration column 45 is provided with a temperature sensor, which will not start the refrigeration fin 46 when it senses heat flow, but will start when it is continuously impacted by normal temperature air flow). The combination of the cold air and the high-speed air flow changes the original normal temperature air flow into cold air with a suitable temperature (the temperature of the cold air will not be too low to ensure that the problem of thermal expansion and cold contraction of aluminum alloy does not occur due to too low temperature). The cold air is then cooled quickly and uniformly through the wide coverage of the inclined air outlet 44, eliminating the local high temperature after preheating and welding. This process not only significantly accelerates the cooling speed of the aluminum alloy, improves the production efficiency, but also ensures the safety and convenience of the operator when handling the welded parts, so that the operator can take out and handle the completed parts more quickly and safely. The heat insulation film avoids the impact of heat flow on the refrigeration fin 46, and the refrigeration column 45 and the refrigeration fin 46 are also provided in the air storage box 47 and the convection port 51 for cooling (not shown in the figure).

[0065] Further, please refer to Figure 7 , Figure 9 and Figure 11 , the cross section of the air permeable barrier net 43 is concave arc shape, the air permeable barrier net 43 is made of high temperature resistant material, the air permeable barrier net 43 is made of high temperature resistant material, on the one hand, effectively resist the thermal damage of the laser welding joint 17, on the other hand, its concave arc cross section design, plays a dual role in the welding operation: can effectively block and collect the residual solder after welding, prevent it from flying around, can also ensure the neatness and safety of the welding environment, in addition, the air permeable barrier net 43 supports regular replacement and maintenance, easy to keep its good working performance and barrier effect for a long time.

[0066] In summary, the present embodiment is provided with the flat wind assembly 5 and the deburring assembly 6, realizes the preheating and cooling treatment of the transverse welding position, and the burr treatment of the welding position, improves the welding quality and the welding efficiency.
