[0041] In the related art, a metal basket is made by welding an "L-shaped" metal bar and a metal hoop. The metal bar includes a first bend and a second bend, and the first bend is perpendicular to the second bend. The metal bar is arranged circumferentially to form a cylindrical structure, wherein the first bend is the bottom of the cylindrical structure, the second bend is the side wall of the cylindrical structure, and the metal hoop is sleeved on the second bend. After the metal bar and the metal hoop are set, the second bend of the metal bar needs to be twisted, and then the metal bar and the metal hoop need to be fixed and finally welded. The metal basket with the second bend of the metal bar twisted can improve the support rigidity.

[0042] However, there is currently a lack of a special welding device for welding the above-mentioned metal baskets. The traditional welding method is manual welding, which has low efficiency and high labor cost.

[0043] In response to the problems existing in the above-mentioned prior art, the present application proposes a welding device, which fixes the metal strip, the metal hoop and the bottom ring through a fixing device, and can twist the second bent portion of the metal strip. The welding device is provided with a first welding mechanism and a second welding mechanism. The first welding mechanism welds the bottom of the cylindrical structure composed of the metal strip and the metal hoop, that is, the first welding mechanism is used to weld the first bent portion and the bottom ring of the metal strip, and the second welding mechanism welds the side wall of the cylindrical structure composed of the metal strip and the metal hoop, that is, the second welding mechanism is used to weld the second bent portion and the metal hoop of the metal strip. The welding device of the present application can realize automatic welding of metal baskets with low labor costs.

[0044] Reference Figures 1 to 13 It will be understood that some embodiments of the present invention provide a welding device that includes a horizontal moving mechanism 300, a fixing device 400, a first welding mechanism 500, and a second welding structure. Specifically, the fixing device 400 is disposed on the horizontal moving mechanism 300 and is used to fix the metal strip 100 and the metal hoop 200, as well as to twist the second bend 120 of the metal strip 100. The first welding mechanism 500 is disposed at one end of the horizontal moving mechanism 300 in the conveying direction and is used to weld the first bend 110 and the bottom ring 210. The second welding mechanism 600 is disposed on both sides of the horizontal moving mechanism 300 in the conveying direction and is used to weld the second bend 120 and the metal hoop 200.

[0045] It should be noted that the horizontal movement mechanism 300 is provided with a base 310, a slide rail 320, and a drive rod 330. There are two slide rails 320, and the base 310 is sandwiched between the two slide rails 320. The base 310 can slide along the length of the slide rails 320. The end of the drive rod 330 is connected to the base 310. The drive rod 330 is driven by a cylinder and drives the base 310 to move. In some embodiments, the drive rod 330 can be configured as a screw, which is driven by a motor. The base 310, the screw, and the motor form a screw module to drive the fixing device 400 to slide horizontally along the slide rails 320.

[0046] It should be noted that the fixing device 400 includes a fixing platform 410 and a base 420. The fixing platform 410 is rotatably mounted on the base 420, which is fixed to the base 310 of the horizontal movement mechanism 300. The fixing platform 410 is used to fix the metal bar 100, and the base 420 is provided with a limiter 421, which is used to fix the metal hoop 200. After the fixing platform 410 and the base 420 secure the metal bar 100 and the metal hoop 200, the fixing platform 410 rotates and twists the second bend 120 of the metal bar 100. The metal bar 100 is first placed on the fixing platform 410 and fixed, primarily by engaging the first bend 110 with the groove at the top of the fixing platform 410, with the second bend 120 pointing vertically downward. The metal hoop 200 is then placed over the second bend 120 and secured by the limiter 421.

[0047] Furthermore, the limiting portion 421 is provided with a retractable protrusion 422, which can be retracted in the horizontal direction. The metal hoops 200 need to be placed on the metal bar 100 one by one. Therefore, when the first metal hoop 200 is placed, only the bottom protrusion 422 is extended, and the upper protrusion 422 is retracted, and the metal hoops 200 are placed upward in sequence.

[0048] It should be noted that the first welding mechanism 500 is equipped with a first base 510, a lifting platform 520, a first driver 530, a first mounting base 540, and a first welding gun 550. The lifting platform 520 is disposed within the first base 510. A guide rail or a lifting cylinder or oil cylinder is provided within the first base 510 to drive the lifting platform 520 up and down. A plurality of first drivers 530 are disposed on the lifting platform 520, and the plurality of first drivers 530 are arranged along the length of the lifting platform 520. The first mounting base 540 is disposed on the first driver 530 and can be driven to move horizontally. The first welding gun 550 is vertically disposed at the end of the first mounting base 540. This arrangement allows the position of the first welding gun 550 to be adjusted according to the position of the metal bar 100 and the bottom ring 210 on the fixing base 640.

[0049] It should be noted that the first welding mechanism 500 is provided with a second machine base 610 and a second welding gun 630. The second machine base 610 is provided with a first slope 620. Multiple second welding guns 630 are arranged on the first slope 620. This arrangement can adapt to the position of the twisted second bending portion 120 to realize automated welding of the metal basket.

[0050] Furthermore, a fixing base 640, a second driver 670 and a second mounting base 680 are provided in the second machine base 610. The fixing base 640 is provided with a second slope 650. The second slope 650 is parallel to the first slope 620. The second slope 650 is arranged with multiple grooves 660. The second driver 670 is arranged in the groove 660 and connected to the second mounting base 680. The second welding gun 630 is arranged on the second mounting base 680. This arrangement can adjust the height of the second welding gun 630 to adapt to the welding of metal baskets of different specifications.

[0051] Furthermore, the second mounting base 680 is provided with a first rotating portion 681 at one end and a second rotating portion 682 at the other end. The second driver 670 is provided with a first push rod 671 and a second push rod 672, which are parallel to each other. The first rotating portion 681 is rotatably connected to the end of the first push rod 671, and the second rotating portion 682 is rotatably connected to the end of the second push rod 672. This arrangement allows the angle of the second welding gun 630 to be adjusted, has a simple structure, and does not require an additional device to drive the second welding gun 630 to rotate.

[0052] It should be noted that the fixing seat 640 is provided with an elastic connection mechanism 700, which includes a clip 710 and an elastic member 720. The side wall of the fixing seat 640 is also provided with a first through hole 800 connected to the groove 660. The elastic member 720 is arranged in the first through hole 800, and the clip 710 is passed through the elastic member 720. The side wall of the second driver 670 is provided with a card slot 730. The elastic member 720 can make the clip 710 be stuck in the card slot 730 to fix the second driver 670. At the same time, pulling the clip 710 outward can make the clip 710 disengage from the card slot 730.

[0053] Furthermore, the second driver 670 is configured as a cylinder, and a second through hole 810 is provided at one end of the fixing seat 640 away from the first through hole 800, and a trachea connector is inserted into the second through hole 810, which is connected to the second driver 670, and the clamping member 710 cooperates with the trachea connector to fix the two ends of the second driver 670.

[0054] A guide member 820 is further provided inside the second base 610 for guiding the push rod of the second driver 670. While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the above embodiments. Various modifications are possible within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention.
