[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 7 As shown, an automatic laser welding system for an aluminum pot 100 and a welding nail 101 includes: an aluminum pot conveying device 3, a welding nail conveying device 4 and a laser welding device 5, the aluminum pot conveying device 3 includes a conveyor belt 31, and the conveyor belt 31 is fixed with equidistant positioning parts 32, the positioning parts 32 are used for sleeve installation of the circular aluminum pot 100, the welding nail conveying device 4 is used to convey the welding nail 101 and make the welding nail 101 correspondingly fit the outer surface of the aluminum pot 100; the laser welding device 5 includes two laser welding heads 51, and the two laser welding heads 51 can be respectively aligned with the upper edge 10121 of the connecting part 1012 of the welding nail 101 and the lower edge 10122 of the connecting part 1012 of the welding nail 101.

[0035] In the present application, the aluminum pot 100 is arranged on the aluminum pot conveying device 3 and conveyed, and the welding nail 101 is conveyed by the welding nail conveying device 4. When passing through the laser welding device 5, the two laser welding heads 51 respectively weld the aluminum pot 100 at the upper edge 10121 and the lower edge 10122 of the connecting portion 1012 of the welding nail 101. In this process, the aluminum pot 100 and the welding nail 101 continue to move horizontally, allowing the welding to be completed during the movement. Compared with the traditional rotary laser welding, this method significantly improves the welding efficiency.

[0036] The greatest advantage of the present application is that the aluminum pot 100 and the welding nail 101 are always in a moving state during the welding process without stopping. In this way, the laser welding device 5 can complete the welding during the movement of the aluminum pot 100 and the welding nail 101, thereby greatly improving the welding efficiency.

[0037] In the present application, the movement of the conveyor belt 31 is achieved by an existing driving method.

[0038] The aluminum pot conveying device 3 and the welding nail conveying device 4 are at least partially arranged in parallel, and the laser welding device 5 is arranged at a position where the aluminum pot conveying device 3 and the welding nail conveying device 4 are arranged in parallel.

[0039] Specifically, it also includes a clamping device 6, which includes a first fixed frame 65, an adjusting frame 61, a push rod motor 62, a cylinder 63, and a pressure plate 64. The adjusting frame 61 is slidably set on the first fixed frame 65, the push rod motor 62 is fixed on the first fixed frame 65, and the push rod of the push rod motor 62 is connected to the adjusting frame 61, which is used to drive the adjusting frame 61 to move back and forth along the conveying direction of the conveyor belt 31. The cylinder 63 is fixed on the adjusting frame 61, and the pressure plate 64 is fixed on the piston rod of the cylinder 63. The clamping device 6 is set at the position corresponding to the laser welding device 5, and the clamping device 6 is used to press the aluminum pot 100 moved to the laser welding device 5 on the positioning portion 32.

[0040] When the aluminum pot 100 is placed on the aluminum pot conveying device 3 and moves to the corresponding position of the laser welding device 5, the push rod motor 62 is started to drive the adjustment frame 61 to move with the aluminum pot 100. At the same time, the cylinder 63 drives the pressing plate 64 to press on the aluminum pot 100 to prevent the aluminum pot 100 from moving or detaching from the positioning part 32 during the welding process to avoid welding failure. After the welding is completed, the pressing device 6 is reset to prepare for the next step.

[0041] Specifically, the laser welding device 5 also includes a compensation mechanism 52 for automatically adjusting the distance between the laser welding head 51 and the aluminum pot 100 according to the curvature of the aluminum pot 100. The compensation mechanism 52 includes a second fixed frame 521, a mobile frame 522, an extrusion rod 523, and an extrusion wheel 524. The mobile frame 522 is slidably arranged on the second fixed frame 521, the extrusion rod 523 is fixed on the mobile frame 522, and the extrusion wheel 524 is rotatably arranged at the end of the extrusion rod 523. The extrusion wheel 524 can contact the outer surface of the positioning portion 32, and the positioning portion 32 has The abutment part 321 is directly at the same welding position as the aluminum pot 100, and the extrusion wheel 524 is extruded on the abutment part 321; the movable frame 522 is connected to the second fixed frame 521 through a plurality of springs 525, and the first limit block 5211 and the second limit block 5212 are detachably installed on the second fixed frame 521, and the movable frame 522 is arranged between the first limit block 5211 and the second limit block 5212, and can be abutted against the first limit block 5211 or the second limit block 5212, wherein the laser welding head 51 is fixed on the movable frame 522.

[0042] Taking into account that the surface of the aluminum pot 100 has a curvature, in order to ensure that the welding effect between the aluminum pot 100 and the connecting part 1012 of the welding nail 101 is optimal, the compensation mechanism 52 is adjusted so that the laser welding head 51 can be consistent with the welding position of the aluminum pot 100 and the connecting part 1012 of the welding nail 101, thereby obtaining a better welding effect.

[0043] When one of the positioning parts 32 moves to the front side of the laser welding device 5 and contacts the extrusion wheel 524, the laser welding head 51 starts welding. During the movement of the positioning part 32, the extrusion wheel 524 starts to be pushed, which drives the moving frame 522 to start moving. Through the action of the tension spring, the extrusion wheel 524 can be tightly attached to the positioning part 32 to ensure that a fixed distance is maintained between the laser welding head 51 and the positioning part 32. The first limit block 5211 and the second limit block 5212 are used to control the movement of the moving frame 522 within a preset range, effectively preventing the laser welding head 51 from touching other parts to prevent damage.

[0044] Specifically, the welding nail conveying device 4 includes a third fixed frame, a conveying guide rail 41, and a guide pressure block 42. The conveying guide rail 41 is fixed on the third fixed frame. A plurality of sliders 43 are slidably arranged on the conveying guide rail 41. Adjacent sliders 43 are hingedly connected by connecting rods 431. A clamping assembly 44 is slidably arranged on the slider 43. The clamping assembly 44 includes a first pressure block 441 and a second pressure block 442. The first pressure block 441 is slidably arranged on the slider 43. A fixing rod 4411 is fixed on the first pressure block 441. A fixing block 432 is fixed on the slider 43. The fixing rod 4411 passes through the fixing block 432 and can slide relative to the fixing block 432. The end of the fixing rod 4411 is connected to the fixing block 432 through a first compression spring 443. A first slide groove 4412 is provided on the first pressure block 441, and a second pressure block 442 is provided There is a second slide groove 4421 corresponding to the first half groove, a first half pressure ring 444 is slidably arranged in the first slide groove 4412, a second half pressure ring 445 is slidably arranged in the second slide groove 4421, the first half pressure ring 444 is connected to the first pressure block 441 through a second pressure spring 446, and the second half pressure ring 445 is connected to the second pressure block 442 through a third pressure spring 447, the first half pressure ring 444 and the second half pressure ring 445 form a clamping part for clamping the main body 1011 of the welding nail 101, the guide pressure block 42 is fixed on the second fixing frame 521, and is arranged at the corresponding position of the laser welding device 5, the guide pressure block 42 can abut against the second pressure block 442, so that when the welding nail 101 moves to the position of the laser welding device 5, the second pressure block 442 moves toward the direction of the first pressure block 441 and is used to clamp the main body 1011 of the welding nail 101.

[0045] After the welding nail 101 is set in the clamping assembly 44, when the slider 43 moves to the position of the guide pressing block 42, the first pressing block 441 of the clamping assembly 44 moves toward the second pressing block 442, so that the first half pressing ring 444 on the first pressing block 441 and the second half pressing ring 445 on the second pressing block 442 clamp the main body 1011 of the welding nail 101, thereby preventing the welding from moving during the welding process. In addition, the first half pressing ring 444 is connected to the first pressing block 441 through the second compression spring 446, and the second half pressing ring 445 is connected to the second pressing block 442 through the third compression spring 447. After the connection part 1012 of the welding nail 101 contacts the surface of the aluminum pot 100, it can only fit through the second compression spring 446 and the third compression spring 447 to avoid welding failure.

[0046] Among them, the first pressure block 441 is slidably set on the slider 43, a fixing rod 4411 is fixed on the first pressure block 441, a fixing block 432 is fixed on the slider 43, the fixing rod 4411 passes through the fixing block 432 and can slide relative to the fixing block 432, and the end of the fixing rod 4411 is connected to the fixing block 432 through the first compression spring 443; this partial structure can maintain the slider 43 at a preset position, and even if it deviates, it can be reset under the action of the first tension spring, so that the position of clamping the welding nail 101 can be kept consistent each time.

[0047] In the present application, the movement of the slider 43 on the conveying guide rail 41 is achieved by an existing driving method, such as a chain or a gear rack structure.

[0048] Specifically, a mounting frame 411 is fixed on the conveying guide rail 41, a pushing motor 412 is fixed on the mounting frame 411, a pushing block 413 is fixed on the push rod of the pushing motor 412, and the pushing block 413 can abut against the first pressing block 441 and the second pressing block 442 to move the first pressing block 441 and the second pressing block 442 toward the aluminum pot conveying device 3.

[0049] When the slider 43 moves to the position of the mounting bracket 411, the motor 412 is started, driving the push block 413 to move. The push block 413 squeezes the first pressure block 441 and the second pressure block 442 to move toward the aluminum pot 100, so that the welding nail 101 on the clamping assembly 44 can be against the aluminum pot 100. At the same time, when the welding nail 101 is against the aluminum pot 100, the welding nail 101 can drive the first half pressure ring 444 and the second half pressure ring 445 to move inward, so that the connecting part 1012 of the welding nail 101 is automatically adapted to the surface of the aluminum pot 100, thereby preventing the welding nail 101 from causing damage to the surface of the aluminum pot 100.

[0051] This design enables the first pressing block 441 to move up and down relative to the second pressing block 442 . After the external force on the first pressing block 441 is released, the first pressing block 441 is separated from the second pressing block 442 by the fourth compression spring 4423 .
