[0036] The following is combined with Figure 1 —5 Provide further details of this application.

[0037] The embodiment of the present application discloses a large-scale container automatic wire feeding laser welding machine.

[0038] Example 1

[0039] Reference Figure 1 , 2A large-scale container laser automatic wire feeding welding machine comprises a main shell 1, a cavity with an installation structure is opened in the middle of the main shell 1, an operating table 2 is fixedly arranged on one side of the top surface of the main shell 1, a welding wire reel 6 is rotatably arranged at one end of the side wall of the cavity of the main shell 1, and a welding wire for welding is wound on the surface of the welding wire reel 6, a correction plate 5 is fixedly arranged on one side below the welding wire reel 6 at the bottom of the cavity of the main shell 1 by screws, and a through hole from large to small is opened in the middle of the correction plate 5.

[0040] It should be noted that the operating table 2 penetrates through the cavity of the main shell 1 and is connected to a system electrical control system, a water cooler and other structures. Due to conventional existing technologies, the principle will not be described in detail.

[0041] Through the above arrangement, the personnel debug the operating table 2 to control the electrical control system inside the main shell 1, and manipulate the subsequent wire feeding mechanism 3 and welding mechanism 4 to perform automatic wire feeding and automatic welding operations, thereby forming an automated production process.

[0042] Reference Figure 2 , 3 A wire feeding mechanism 3 is provided in the cavity of the main shell 1 at the other side of the correction plate 5 away from the welding wire reel 6. The wire feeding mechanism 3 includes a wire feeding shell 31 aligned with the correction plate 5 and fixedly arranged at the bottom of the cavity of the main shell 1. A second motor 10 is fixedly arranged on one side of the outer surface of the wire feeding shell 31. The interior of the wire feeding shell 31 is hollow, and a rotating gear 32 is rotatably arranged in the middle of the inner surface. The rotating rod of the rotating gear 32 movably penetrates the wire feeding shell 31 and is fixedly connected to the output shaft of the second motor 10. The inner surface of the wire feeding shell 31 is rotatably connected with pressure plates 37 on both sides above the rotating gear 32. The two pressure plates 37 rotate in opposite directions and have side grooves at the tails. A groove is provided at the bottom of the pressure plate 37 from bottom to top. The grooves of the two pressure plates 37 and the inner surface of the wire feeding shell 31 are located on both sides of the rotating gear 32. The limiting wheels 33 are rotatably connected. The two sets of limiting wheels 33 in an upper and lower relationship abut and align with each other, and an annular groove is provided on the surface of the limiting wheel 33.

[0043] Reference Figure 2 , 3 A force gear 34 is fixed on one side of each of the four limiting wheels 33 , and the two groups of force gears 34 in an upper and lower relationship are meshed and connected with each other, and the two force gears 34 located at the bottom of the wire feeding housing 31 are respectively meshed and connected with the two sides of the tooth surface of the rotating gear 32 .

[0044] It should be noted that the width of the slot on the surface of the limiting wheel 33 is consistent with the width of the welding wire being transported, which guides the welding wire and has a certain degree of fixity to prevent the welding wire from being misplaced.

[0045] Through the above arrangement, the rotating gear 32 provides power to drive the two force gears 34 at the bottom to rotate. The rotation of the two force gears 34 at the bottom simultaneously drives the two force gears 34 at the top to rotate. As the four force gears 34 rotate, the four limiting wheels 33 rotate in the synchronous direction of the force gears 34. When the four limiting wheels 33 rotate, they drive the welding wire in the groove to move, thereby completing the main transmission process of the welding wire.

[0046] Reference Figure 2 , 3 , 5. Rotating plates 35 are rotatably provided on both sides of the top of the wire feeding housing 31 and aligned with the side grooves of the pressure plate 37. The bottom of the two rotating plates 35 close to one end of the side groove of the pressure plate 37 is rotatably connected with a pressure wheel 36, and the width of the pressure wheel 36 is consistent with the width of the side groove of the pressure plate 37. A wire inlet 38a is provided on the outer surface of the wire feeding housing 31 at the abutment position of the grooves of the two limiting wheels 33. The wire inlet 38a is aligned with the through hole of the correction plate 5 and penetrates the wire feeding housing 31 to form a connection. A wire outlet 38c is provided on the side of the outer surface of the wire feeding housing 31 away from the wire inlet 38a. The wire outlet 38c penetrates the interior of the wire feeding housing 31 to achieve connection with the outside, and a hose housing 39 is fixedly provided at the docking interface connected with the outside. The welding wire hose inside the hose housing 39 is aligned with the wire outlet 38c, and a support tube body 38b is fixedly provided on the inner wall of the wire feeding housing 31 cavity between the wire inlet 38a and the wire outlet 38c.

[0047] Through the above arrangement, the welding wire is inserted into the wire inlet 38a through the correction plate 5 and thus enters the wire feeding housing 31, and then is clamped and inserted between the grooves of the two limiting wheels 33. As the limiting wheels 33 rotate, the welding wire is transported to the support tube body 38b and then inserted between the grooves of the other two limiting wheels 33 again, and finally is transported from the wire outlet 38c to the welding wire hose in the hose housing 39 to guide the transportation of the welding wire.

[0048] Reference Figure 2 , 4The welding mechanism 4 includes a moving drive mechanism 48 fixedly arranged on the inner surface of the main shell 1 at one end away from the welding wire reel 6, a connecting shell 46 is threadedly arranged on the surface of the transverse lead screw at the bottom of the moving drive mechanism 48, a groove is provided on one side of the connecting shell 46, and a lead screw is rotatably arranged in the groove, a first motor 47 is fixedly arranged at the bottom of the connecting shell 46 by screws, an output shaft of the first motor 47 movably passes through the bottom of the connecting shell 46 and is fixedly connected to the lead screw, a connecting plate 45 is threadedly connected to the surface of the lead screw of the connecting shell 46, an end of the connecting plate 45 away from the connecting shell 46 is annular, and a laser welding head 41 is fixedly arranged on the inner surface of the annular ring, a fixing fixture 42 is welded and fixed on one side of the bottom surface of the laser welding head 41, a rotating fixture 43 is rotatably arranged on the other end of the fixing fixture 42 relative to the laser welding head 41, a welding wire head 44 is fixedly arranged in the groove at the bottom of the rotating fixture 43, and the wire inlet of the welding wire head 44 is fixedly connected to the welding wire hose of the hose shell 39.

[0049] It should be noted that the optical fiber at the top of the laser welding head 41 is provided with a laser generator for transmitting laser light, and the laser welding head 41 is connected to a water cooler so as to have the function of lowering the temperature.

[0050] Through the above-mentioned arrangement, the operating platform 2 transmits signals to control the mobile driving mechanism 48 to move horizontally and vertically, thereby driving the connecting shell 46 to move synchronously, and the connecting shell 46 is fixedly connected to the laser welding head 41 through the connecting plate 45, thereby controlling the horizontal and vertical movement of the laser welding head 41. At the same time, the operating platform 2 controls the first motor 47 to rotate so that the connecting plate 45 is lifted and lowered along the screw surface of the connecting shell 46, thereby driving the laser welding head 41 to move up and down synchronously.

[0051] Reference Figure 1 , 2 A material fixing disk 7 is rotatably arranged at the bottom of the cavity of the main shell 1 in a position aligned with the laser welding head 41, and a groove on the surface of the material fixing disk 7 is aligned with the welding point of the laser welding head 41. A feed port 8 is arranged on the side of the outer surface of the main shell 1 close to the material fixing disk 7, and a baffle that can be opened and closed is rotatably arranged at the feed port 8. A heat dissipation window 9 is arranged on the side of the outer surface of the main shell 1 adjacent to the feed port 8, and a screen formed by winding iron wire is installed on the heat dissipation window 9, and the aperture of the screen is set between 1 and 1.5 cm.

[0052] Through the above arrangement, the material to be welded is transported from the feed port 8 to the surface of the material fixing disk 7 for fixation, and the material fixing disk 7 keeps rotating so that the laser welding head 41 can continuously weld a large amount of material, and at the same time, the hot air generated by welding is discharged to the outside of the device through the heat dissipation window 9.

[0053] Among them, the device also includes a laser generator, a welding wire tube body, a laser welding head 41, a welding wire head 44, a first motor 47, a mobile drive mechanism 48, a second motor 10, a material fixing disk 7, and the rotating device and material fixing method of the material fixing disk 7 are all existing technologies, and their structural principles are not described in detail. The second motor 10 type is set to a vertical output motor.

[0054] The implementation principle of a large container automatic laser wire feeding welding machine according to the embodiment of the present application is as follows: when using the device, a person opens the baffle closed at the feed port 8, fixes the material on the surface of the material fixing disk 7, and then adjusts the parameters of the operating table 2, controls the mobile driving mechanism 48 to translate, and the mobile driving mechanism 48 drives the connecting shell 46 to move the laser welding head 41 synchronously. When the laser welding head 41 moves until it is aligned with the welding point of the material fixing disk 7, the operating table 2 sends an electrical signal to control the first motor 47 to rotate, so that the connecting plate 45 moves downward, thereby reducing the height of the laser welding head 41 to achieve a safe welding distance;

[0055] After the personnel have completed the parameter debugging of the operating table 2, the second motor 10 is started to rotate, and the second motor 10 drives the rotating gear 32 to rotate, and the rotating gear 32 drives the four mutually meshing force gears 34 to rotate synchronously, so that the four limiting wheels 33 that are in contact with each other rotate clockwise and counterclockwise respectively. With the rotation of the four limiting wheels 33, a pulling force is applied to the welding wire in the groove of the limiting wheel 33, and then the welding wire is transmitted to the welding wire tube of the hose housing 39 through the wire outlet 38c, and finally output by the welding wire head 44;

[0056] At this time, the operator controls the operating console 2 to start the laser transmitter to emit laser, and the laser is transmitted to the laser welding head 41 through the optical fiber and emitted from the bottom of the laser welding head 41, melting the welding wire while performing welding operations on the material.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
