[0021] In the embodiment, Figures 1-5Provided is an automatic welding structure for a metal component, including a bracket 1, on which several pipe brackets 2 for placing pipe fittings are provided, and the brackets 2 are evenly distributed along the feeding direction of the bracket 1. A feeding component 3 is provided on the bracket 1, which is used to feed the pipe fittings one by one along the bracket 1. A placement rack 4 is provided at the discharging end of the bracket 1. A vibrating feeding tray 5 for continuously conveying metal plugs is provided on one side of the placement rack 4. A material distributing component 6 is provided at the output end of the vibrating feeding tray 5. A six-axis robot 7 is provided between the vibrating feeding tray 5 and the placement rack 4. A material taking component 8 is provided at the output end of the six-axis robot 7. A rotating platform 9 is provided on one side of the six-axis robot 7. A welding device 10 is provided on the side of the rotating platform 9 away from the six-axis robot 7. Place the metal pipe fitting on the first bracket 2 on the bracket 1, start the feeding component 3, and automatically feed the metal pipe fitting from the current bracket 2 to the next bracket 2 one by one, that is, convey it forward along the preset path of the bracket 1. A placement rack 4 is provided at the discharging end of the bracket 1, which is used to receive and temporarily store the metal pipe fittings that have been fed, and is the material taking position of the metal pipe fittings for the six-axis robot 7. The vibrating feeding tray 5 starts to work, and the metal plugs are orderly arranged and conveyed to the output end one by one through vibration. The material distributing component 6 is located at the output end of the vibrating feeding tray 5 and is responsible for separating the single metal plug from the continuously conveyed materials and preparing for the six-axis robot 7 to grab. Subsequently, the six-axis robot 7 first grabs the metal pipe fitting and places it at the discharging position of the rotating platform 9, then grabs the metal plug, and pre-assembles the metal plug and the metal pipe fitting. Subsequently, the rotating end of the rotating platform 9 rotates to move the metal pipe fitting and the metal plug to the welding position of the welding device 10. The welding device 10 uses existing technology to perform welding operations on the metal pipe fitting and the metal plug.

[0022] Referring to Figures 1-5 , wherein, the bracket 2 includes a mounting seat 21, the mounting seat 21 is arranged on the bracket 1, the cross-section of the mounting seat 21 is arranged in a "V" shape, and a plurality of rollers 22 are rotatably connected to the top of the mounting seat 21;

[0023] Through the above structural arrangement, when the metal pipe fitting is placed on the bracket 2, the lower part of the metal pipe fitting will naturally be embedded in the "V" groove of the mounting seat 21, so that the metal pipe fitting is effectively supported and fixed in the vertical direction. The rollers 22 help to reduce friction and can also guide the pipe fitting to a certain extent.

[0024] Referring to Figures 1-5 , wherein, the feeding component 3 includes a driving motor 31 fixedly installed on the bracket 1. The output end of the driving motor 31 is provided with a crankshaft 32. A connecting rod 33 is rotatably connected to the crankshaft 32. The end of the connecting rod 33 away from the crankshaft 32 is rotatably connected to a pushing frame 34. A plurality of V-shaped grooves 35 are evenly distributed on one side surface of the pushing frame 34, and wear-resistant sheets 36 are welded in the grooves of the V-shaped grooves 35;

[0025] With the above structural arrangement, the driving motor 31 serves as the power source, which can drive the crankshaft 32 to rotate on its own. The rotational motion of the crankshaft 32 is converted into the reciprocating motion of the pusher frame 34 through the connecting rod 33. Along with the reciprocating motion of the pusher frame 34, the V-shaped grooves 35 thereon will sequentially contact the pipe fittings and push them forward. The presence of the wear-resistant plates 36 further enhances the wear resistance of the V-shaped grooves 35, reduces the frictional loss between the pipe fittings and the pusher frame, and extends the service life of the equipment.

[0026] Refer to Figures 1-5 , wherein, both side surfaces of the pusher frame 34 are slidably connected with connecting plates 11, and one side surface of the connecting plate 11 away from the pusher frame 34 is slidably connected to the bracket 1;

[0027] With the above structural arrangement, the pusher frame 34 and the connecting plate 11 and between the connecting plate 11 and the bracket 1 are all slidably connected through slide rails and sliders, ensuring that the pusher frame 34 can continuously push the pipe fittings forward and realize a continuous and stable conveying process.

[0028] Refer to Figures 1-5 , wherein, the material distribution assembly 6 includes a feeding channel 61. One end of the feeding channel 61 is communicated with the discharging end of the vibrating feeding tray 5, and the other end is communicated with a blanking channel 62. A linear vibrator 63 is arranged below the blanking channel 62, and the linear vibrator 63 is used to drive the metal plug to move along the blanking direction of the blanking channel 62. One end of the blanking channel 62 is provided with an electric push rod 64. The output end of the electric push rod 64 is provided with a moving block 65, and one side surface of the moving block 65 abuts against one end of the blanking channel 62. A receiving groove 66 adapted to the metal plug is formed on the moving block 65;

[0029] With the above structural arrangement, the vibrating feeding tray 5 orderly arranges and conveys the metal plugs to the entrance of the feeding channel 61 through its vibrating function. The metal plugs enter the blanking channel 62 along the feeding channel 61. After the linear vibrator 63 is started, linear vibration is generated. This vibration acts on the blanking channel 62 and pushes the metal plugs to move along the blanking direction. When the metal plug moves into the receiving groove 66 communicated with the blanking channel 62, the electric push rod 64 starts to work. The output end of the electric push rod 64 pushes the moving block 65 forward, thereby separating the current metal plug. And a laser sensor is arranged on one side of the moving block 65. When the laser sensor detects that there is a metal plug at the current position, the six-axis robot 7 can perform grasping.

[0030] Refer to Figures 1-5, wherein the material taking member 8 includes a connecting block 81 provided at the output end of the six-axis robot 7, and a first material taking jaw 82 and a second material taking jaw 83 are respectively provided on the connecting block 81, and the first material taking jaw 82 and the second material taking jaw 83 are respectively used for gripping the metal pipe fitting and the metal plug;

[0031] With the above structural arrangement, the six-axis robot 7 has six degrees of freedom and can perform complex movements and positioning in three-dimensional space. The first material taking jaw 82 and the second material taking jaw 83 are respectively designed to grip objects of different shapes and sizes, and both the first material taking jaw 82 and the second material taking jaw 83 are composed of a two-way cylinder and a clamping block provided at the telescopic end of the two-way cylinder. Under the clamping action of the clamping block, the metal pipe fitting and the metal plug can be gripped and released.

[0032] Refer to Figures 1-5 , wherein an installation groove 12 adapted to the outer diameter of the metal pipe fitting is provided at the rotating end of the rotating platform 9;

[0033] With the above structural arrangement, the inner diameter of the installation groove 12 is precisely matched with the outer diameter of the metal pipe fitting. When the metal pipe fitting is placed in the installation groove 12, stable support and fixation can be obtained, reducing the errors and losses caused by the metal pipe fitting shaking or shifting during rotation.
