DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] It should be understood that the present invention can be implemented in different forms and should not be construed as being limited to the embodiments presented herein. On the contrary, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. In the accompanying drawings, the same reference numerals throughout represent the same components.

[0024] The specific structure of the welding smoke treatment system of the vehicle frame flexible automatic welding line in the utility model is combined with reference to Figure 1 and Figure 2 The welding smoke treatment system of the vehicle frame flexible automatic welding line comprises a first production line 100, a second production line 200, a third production line 300 and a fourth production line 400. The first production line 100 and the second production line 200 are arranged in parallel and have the same transmission direction. The third production line 300 and the fourth production line 400 are arranged in parallel and have opposite transmission directions. The transmission rear end of the second production line 200 is aligned with the transmission head end of the fourth production line 400, and the transmission rear end of the first production line 100 is aligned with the transmission rear end of the third production line 300.

[0025] It also includes a welding smoke dust removal device 700, a suction main pipe 720 and a plurality of suction branch pipes 730. The suction main pipe 720 is connected to the welding smoke dust removal device 700. The suction branch pipes 730 are distributed on both sides of the suction main pipe 720 and extend into the workstations of the first production line 100, the second production line 200, the third production line 300 and the fourth production line 400. The first production line 100, the second production line 200, the third production line 300 and the fourth production line 400 are all provided with a first welding smoke suction hood 740.

[0026] Among them, the main suction pipe 720 is distributed between the first production line 100 and the second production line 200, the third production line 300 and the fourth production line 400, and the suction branch pipes 730 are distributed on both sides of the main suction pipe 720. This allows the suction branch pipes 730 to extend into each workstation of the first production line 100, the second production line 200, the third production line 300 and the fourth production line 400. This trunk-type arrangement can also evenly distribute and optimally balance the wind pressure and air volume of each suction branch pipe to achieve the suction effect of each suction port.

[0027] Specifically, a front frame overpass system 500 is installed between the rear of the first production line 100 and the rear of the second production line 200, and a frame assembly overpass system 510 is installed between the rear of the third production line 300 and the front of the fourth production line 400. In this solution, the first production line 100, the second production line 200, the third production line 300 and the fourth production line 400 are distinguished by the front and rear parts in the conveying direction, that is, the upstream in the conveying direction is the front part, and the downstream in the conveying direction is the rear part.

[0028] In the actual implementation process, the frame flexible automatic welding line is used to produce and process wide-body pickup truck frames and narrow-body pickup truck frames respectively. Specifically, the first production line 100, the second production line 200, and the fourth production line 400 are combined to weld wide-body pickup truck frames, and the third production line 300 and the fourth production line 400 are combined to weld narrow-body pickup truck frames. The combination of the first production line 100, the second production line 200, the third production line 300, and the fourth production line 400 in this solution can weld and produce both wide-body and narrow-body pickup truck frames. The frame flexible automatic welding line can be arranged in a factory with limited space, and the wide-body and narrow-body pickup truck frames can be combined and welded in sequence respectively, and the welding process can be carried out automatically, which greatly reduces labor costs and effectively improves the welding accuracy and welding efficiency of the pickup truck frames. During use of the flexible automated welding line for the vehicle frame in this scheme, the welding smoke generated by all production lines can be processed by the welding smoke treatment system. Specifically, the welding smoke dust removal device 700 can be turned on, and the suction branch pipe 730 can be extended to each workstation of the first production line 100, the second production line 200, the third production line 300 and the fourth production line 400 to suck the welding smoke generated by each workstation and then draw it to the welding smoke dust removal device 700 through the suction main pipe 720 to process the welding smoke.

[0029] In some embodiments, a main pipeline flame arrester 710 is disposed at the front end of the suction main pipeline 720, and the main pipeline flame arrester 710 is connected to the welding smoke dust removal device 700. For example, Figure 2 As shown, the main duct flame arrester 710 can prevent the flame in the welding smoke from entering the welding smoke dust removal device 700, effectively preventing the risk of combustion in the welding smoke treatment system.

[0030] In some embodiments, the first welding fume extraction hood 740 on the first production line 100, the second production line 200, and the fourth production line 400 is located at the rear thereof, and the first welding fume extraction hood 740 on the third production line 300 is located at the front thereof. For example, Figure 2As shown, in the actual implementation process, the first production line 100, the second production line 200, the middle and rear part of the fourth production line 400, and the middle and front part of the third production line 300 all have welding stations. A first welding smoke suction hood 740 is used to cover the top of the station, and a suction branch pipe 730 is used to extract the welding smoke, which can effectively and comprehensively collect the welding smoke generated by welding.

[0031] In some embodiments, the first welding fume extraction hood 740 has 3-5 extraction branch pipes 730. For example, Figure 2 As shown, since the first welding smoke extraction hood 740 has a certain length, the extraction branch pipes 730 can be properly arranged inside it according to the number of workstations.

[0032] In some embodiments, an air curtain is provided in the first welding smoke suction hood 740. Under the effect of the air curtain, welding smoke can enter the suction branch pipe 730 more quickly.

[0033] In some embodiments, the suction branch pipe 730 is provided with an on-off fan 731. Figure 2 As shown, the on-off fan 731 can open and close the suction branch pipe 730 independently, and then use the suction branch pipe 730 according to the welding process, so that the power of the welding smoke treatment system can be maximized.

[0034] In some embodiments, the front of the first production line 100 and the front of the second production line 200 are provided with a second welding fume extraction hood 750, and there are two second welding fume extraction hoods 750 on the second production line 200. Figure 2 As shown, the second welding smoke extraction hood 750 can specifically extract the welding smoke at the front ends of the first production line 100 and the second production line 200, further improving the effect of welding smoke treatment.

[0035] In some embodiments, on the first production line 100 and the second production line 200, an arc welding room 760 is disposed between the second welding fume extraction hood 750 and the first welding fume extraction hood 740, and the arc welding room 760 is closely attached to the first welding fume extraction hood 740. For example, Figure 2 As shown, the arc welding room 760 can facilitate arc welding operations. Its structure adopts a closed design, and by cooperating with the suction branch pipe 730, it can comprehensively reduce welding smoke during arc welding.

[0036] In some embodiments, at least one extraction branch duct 730 is provided in the second welding fume extraction hood 750 and the arc welding room 760. For example, Figure 2As shown, the suction branch pipe 730 is used in conjunction with the second welding smoke suction hood 750 and the arc welding room 760, respectively, so that the welding smoke treatment system can more comprehensively absorb the welding smoke at each workstation and perform treatment.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
