[0002] Brazing refers to a welding method in which a filler metal with a melting point lower than that of the workpiece and the workpiece are simultaneously heated to the melting temperature of the filler metal, and then the liquid filler metal is used to fill the gaps of the solid workpiece to connect the metals.

[0003] For example, Chinese Patent Publication No. CN108746917A discloses the following technical solution: a welding robot device, the structure of which includes a filler metal box, a welding main body, a cabinet door, support feet, a bottom cabinet, a hinge, a welding seat, and a connecting pipe. The filler metal box is fixedly installed on the upper surface of the welding main body. The cabinet door is installed on the surface of the bottom cabinet through a hinge. There are four support feet in total and they are fixedly installed at the four corners of the bottom of the bottom cabinet. The upper surface of the bottom cabinet is welded to the lower surface of the welding main body. The welding seat is welded to the upper surface of the bottom cabinet and is located on the left side of the welding main body. The upper end of the connecting pipe is connected to the filler metal box, and the lower end of the connecting pipe is connected to the welding main body. The following problems exist in the prior art: In the above device, by pulling the baffle, the filler metal flows through the filler metal outlet pipe to the baffle, and then from the filler metal outlet pipe to the nozzle. When brazing the hinge, it is not necessary to perform long-distance brazing, but to perform brazing on both sides of the hinge. Therefore, it is controlled by the baffle and it is not easy to control the flow rate well. Summary of the Invention

[0025] It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other. The following will refer to the drawings and combine with embodiments to detail this application.

[0026] Example 1, please refer to Figures 1 - 7, this embodiment provides a brazing device for a refrigerator hinge, including: an operating table 1; a slide rail 2, which is fixedly connected to the upper end of the operating table 1; a support leg 3, which is fixedly connected to the bottom of the operating table 1; an L-shaped plate 4, which is fixedly connected to the upper end of the operating table 1; a motor 51 is fixedly connected to the outer wall of the L-shaped plate 4, the output shaft of the motor 51 is fixedly connected to a turntable 52, a fixed shaft 53 is fixedly connected to the outer wall of the turntable 52, a connecting rod 54 is fixedly sleeved on the outer wall of the fixed shaft 53, a connecting shaft 55 is rotatably connected to the outer wall of the connecting rod 54, the other end of the connecting shaft 55 is rotatably connected to a moving block 56, a chute 57 is opened on the outer wall of the moving block 56, an installation shaft 58 is rotatably connected to the inner side of the L-shaped plate 4, an installation rod 59 is fixedly sleeved on the outer wall of the installation shaft 58, a welding head 510 is fixedly sleeved at the other end of the installation rod 59. The welding head 510 is a key part in the brazing device for actually performing welding. The brazing process of the hinge is completed through its contact with the brazing solution. A sliding shaft 515 is fixedly connected to the outer wall of the installation rod 59, and the sliding shaft 515 is slidably connected inside the chute 57. A guide rail 511 is fixedly connected to the inner side of the L-shaped plate 4, and the moving block 56 is slidably connected to the outer wall of the guide rail 511. An arc-shaped baffle 512 is fixedly connected to the side of the L-shaped plate 4. The design of the arc-shaped baffle 512 can prevent the overflow of the brazing molten liquid, ensure the working space of the welding head 510 is clean and effectively prevent the waste of the solution. A melting box 513 is fixedly connected to the top of the L-shaped plate 4. A connecting pipe 514 is assembled at the liquid outlet at the bottom of the melting box 513, and the other end of the connecting pipe 514 is communicated with the welding head 510. The melting box 513 is a device for heating and melting the brazing material.

[0027] In use, first place the two parts of the hinge in the positioning plates 62 on both sides respectively. Then, start the heating element inside the melting box 513 to heat the brazing material inside it until it melts. Then, the melted brazing liquid will flow into the inside of the welding head 510 through the connecting pipe 514. Next, start the motor 51 to drive the turntable 52 to rotate. The fixed shaft 53 on the outer wall of the turntable 52 will rotate around the center of the turntable 52. Then, one end of the connecting rod 54 fixedly sleeved outside the fixed shaft 53 will also rotate around the turntable 52. Since the height of the bottom of the connecting rod 54 changes with the position of the fixed shaft 53 during the rotation, the top of the connecting rod 54 will push the moving block 56 hinged to it, and the moving block 56 will slide up and down on the outer wall of the guide rail 511. When the moving block 56 slides up and down, the sliding shaft 515 slidingly connected in the chute 57 opened on its outer wall will slide and its height will also change. When the moving block 56 descends, the height of the sliding shaft 515 will also descend accordingly, and then drive the mounting rod 59 to rotate downward around the mounting shaft 58 as the rotation center. Then, the welding head 510 at the other end of the mounting rod 59 will rotate accordingly. When the welding head 510 rotates and moves by an angle, the bottom end of the welding head 510 will leave the surface of the arc-shaped baffle 512, so that the brazing liquid can flow at the welding seam. When the moving block 56 moves upward, the height of the sliding shaft 515 will rise, and then the mounting rod 59 will rotate upward around the mounting shaft 58 as the center, driving the bottom end of the welding head 510 to rotate to fit the surface of the arc-shaped baffle 512, thus avoiding the continuous outflow of the brazing solution and causing waste, and at the same time leaving time for the cooling of the already outflowed brazing solution.

[0028] Embodiment 2, please refer to Figures 1 - 7 , on the basis of Embodiment 1, an adjusting component 6 is assembled inside the L-shaped plate 4. The adjusting component 6 includes a bearing plate 61. The bearing plate 61 is slidably connected to the upper end of the slide rail 2. A positioning plate 62 is fixedly connected to the upper end of the bearing plate 61. A rotating rod 63 is rotatably connected inside the L-shaped plate 4. A runner 64 and a gear 68 are fixedly sleeved on the outer wall of the rotating rod 63. An arc-shaped groove 65 and a U-shaped groove 66 are opened on the outer wall of the runner 64. A semi-circular block 67 and a linkage shaft 610 are fixedly connected to the outer wall of the turntable 52. A toothed plate 69 is fixedly connected to the outer wall of one side positioning plate 62. The arc surface of one side of the semi-circular block 67 is consistent with the inner wall radian of the arc-shaped groove 65. The diameter of the linkage shaft 610 matches the width of the U-shaped groove 66. The gear 68 is located above the toothed plate 69 and meshes with it.

[0029] During use, when the turntable 52 rotates, it drives the linkage shaft 610 to rotate. When the linkage shaft 610 rotates into the U-shaped groove 66 formed on the outer wall of the runner 64, if the linkage shaft 610 continues to rotate at this time, it can drive the runner 64 to rotate. Then the runner 64 will drive. When the runner 64 rotates, it drives the lever 63 to rotate. Then the gear 68 located on the outer wall of the lever 63 also rotates. Then the toothed plate 69 engaged with it will move accordingly. Thus, it can drive the positioning plate 62 and the bearing plate 61 to slide on the upper end of the slide rail 2. Furthermore, it can drive the hinge fixed to the positioning plate 62 to move, so that other welding points can be moved to the lower end of the welding head 510. When the linkage shaft 610 slides out of the U-shaped groove 66, the arc-shaped groove 65 formed on the side of the runner 64 will fit with the arc-shaped surface of the semi-circular block 67, thus preventing the runner 64 from continuing to rotate under the action of inertia.

[0030] Embodiment 3. Please refer to Figures 1 - 7 , on the basis of Embodiment 1, a cooling component 7 is assembled at the bottom of the operating table 1. The cooling component 7 includes a blower 71. The blower 71 is fixedly connected to the bottom of the operating table 1. An air supply pipe 72 is assembled at the air outlet of the blower 71. The other end of the air supply pipe 72 is fixedly connected to an air supply hood 73. A ventilation opening 74 is formed in the middle of the operating table 1. A fixed block 75 is fixedly connected to the upper end of the operating table 1. A through hole is formed in the middle of the fixed block 75 and a resisting rod 76 is slidably connected inside the through hole. Two ends of the resisting rod 76 are respectively fixedly connected with a resisting block 77 and a closing plate 78. A moving plate 710 is fixedly connected to the bottom of the bearing plate 61. A spring 79 is fixedly connected between the fixed block 75 and the resisting block 77. The top of the air supply hood 73 is fixedly connected to the operating table 1. A plurality of grooves are formed on the side of the moving plate 710 away from the slide rail 2. The design purpose of the cooling component 7 is to provide effective heat dissipation during the brazing process to prevent overheating from damaging the equipment.

[0031] During use, when the bearing plate 61 moves, it drives the moving plate 710 at its bottom to move accordingly. When the bearing plate 61 is in the welding position, at this time the groove of the moving plate 710 contacts the resisting block 77. At this time, the closing plate 78 is located above the ventilation opening 74. Thus, the wind generated by the blower 71 will not be transported upward to the upper end of the operating table 1. When the welding is completed, the bearing plate 61 will move accordingly. At this time, the moving plate 710 will also move simultaneously. The place where the resisting block 77 contacts the moving plate 710 changes from a groove to a protruding end. Thus, the resisting block 77 will compress the spring 79 and drive the resisting rod 76 away from the moving plate 710. Then the closing plate 78 will also move accordingly. Then the ventilation opening 74 will also move accordingly. Then the blower 71 will transport the generated wind through the air supply pipe 72 and the air supply hood 73 and send the wind through the ventilation opening 74 to the bottom of the welding area, thus achieving cooling and temperature reduction.

[0032] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
