[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model addresses the problems of tungsten needles requiring manual installation, resulting in poor continuity, errors, and deviations during manual operation, thus reducing product yield and consistency. Furthermore, the welding process requires manual operation, leading to low automation levels, high operational difficulty, and reduced production efficiency. This invention provides a solution... Figures 1-3The tungsten wire welding device with an automatic needle feeding mechanism shown includes a worktable 1. A storage shell 2 and a fixing block 5 are fixedly installed on both sides of the top surface of the worktable 1. A first material groove 21 is formed through the bottom of the storage shell 2, and a second material groove 51 is formed on the top surface of the fixing block 5. A pushing assembly 3 is slidably installed inside both the first and second material grooves 21. The pushing assembly 3 includes a square plate 31, a connecting plate 32, and a pushing plate 33. The connecting plate 32 is fixedly connected to both ends of the square plate 31, and the pushing plate 33 is fixedly connected to the end of the connecting plate 32. The pushing plate 33 is circular, and its shape matches that of the first material groove 21. A distributing groove 23 is formed inside the storage shell 2. The distributing groove 23 is herringbone shaped, and its bottom sides are connected to the sides of the first material groove 21. The storage shell 2 contains... Multiple tungsten needles are placed on the top surface of the second material trough 51, with the ends of the tungsten wires facing the direction of the tungsten needles. The tungsten needles are evenly separated to both sides by the material distribution trough 23 and fall into the first material trough 21 below through the inclined channel of the material distribution trough 23. The first material trough 21 has circular grooves on both sides. After the tungsten needles fall into the circular grooves, the pushing component 3 pushes the tungsten needles out of the circular grooves. At the same time as the tungsten needles are pushed out, the pushing component 3 on the other side pushes the tungsten wire towards the tungsten needles. When the tungsten needles contact the ends of the tungsten wires, the pushing component 3 stops moving. By synchronously moving the tungsten wires and tungsten needles, the level of automation is improved, manual intervention is reduced, the difficulty of operation is reduced, and the production efficiency is improved. The square plate 31 is a plate connected to the power mechanism, and the connecting plate 32 helps to connect the square plate 31 to the pushing plate 33.

[0027] It should be noted that the circular groove holds one tungsten needle at a time. When the tungsten needle is pushed out, the pusher component 3 returns to its original position, and the top tungsten needle continues to fall. This process is repeated continuously, achieving good continuity. Through the cooperation of the components, the effect of automatic needle feeding is achieved, avoiding errors and deviations caused by human factors, improving the yield and consistency of the product, and reducing reliance on manual labor, thus lowering the company's labor costs.

[0028] In this utility model, the portal frame 6 is located on both sides of the welding seat 4. A second electric cylinder 61 is fixedly connected to the top surface of the outer wall of the portal frame 6. A fixing plate 62 is provided in the middle of the second electric cylinder 61. The end of the piston rod of the second electric cylinder 61 passes through the top of the portal frame 6 and is fixedly connected to the top surface of the fixing plate 62. The fixing plate 62 is fixedly connected to the welding head 63. When welding, the ends of the tungsten needle and tungsten wire are located on the welding seat 4. When welding, the position of the portal frame 6 is adjusted. After adjusting to the appropriate position, the second electric cylinder 61 is opened. The second electric cylinder 61 drives the piston rod on it to move. The movement of the piston rod drives the fixing plate 62 to move. When the welding head 63 reaches the position of the tungsten needle and tungsten wire, the welding work begins.

[0029] Furthermore, a portal frame 6 is provided on the top surface of the workbench 1, and two welding heads 63 are provided in the middle of the portal frame 6; the portal frame 6 helps to fix the welding heads 63, and the welding heads 63 have power supply and other equipment that cooperate with them, which is a mature existing technology and is not shown in the figure, so it will not be described in detail here.

[0030] It should be noted that the position of the gantry frame 6 is movable. This is a mature technology in the existing field and will not be elaborated here. When encountering tungsten wires and tungsten needles of different lengths, the position of the gantry frame 6 can be moved to adjust the welding head 63, which facilitates accurate welding.

[0031] In this utility model, a welding seat 4 is fixedly connected to the top surface of the workbench 1.

A gear 41 is rotatably arranged in the middle of the welding seat 4. A first rack 42 and a second rack 43 are slidably arranged inside the welding seat 4. The ends of the first rack 42 and the second rack 43 that are far apart from each other are fixedly connected to the side wall of the square plate 31. The first rack 42 and the second rack 43 mesh with the gear 41. When the square plate 31 located inside the storage shell 2 moves, it drives the second rack 43 to move. The movement of the second rack 43 drives the gear 41 to rotate. The rotation of the gear 41 drives the first rack 42 to move. Through the cooperation of the components, the contact between the tungsten needle and the tungsten wire is realized, which facilitates the smooth progress of subsequent welding work. During welding, the tungsten needle and the tungsten wire are located on the top surface of the welding seat 4.

[0032] It should be noted that welding grooves 44 are provided on both sides of the top surface of the welding seat 4. The welding grooves 44 are arc-shaped. The bottom of the welding grooves 44 has the same arc size as the bottom of the first material groove 21 and the second material groove 51. The tungsten needle pushed out in the first material groove 21 can smoothly enter the welding grooves 44, and the tungsten wire on the second material groove 51 can also smoothly enter the welding grooves 44, which facilitates the subsequent welding work.

[0033] In this utility model, a first electric cylinder 24 is fixedly installed on the top surface of the workbench 1. The piston rod end of the first electric cylinder 24 is fixedly connected to the side wall of the square plate 31 located inside the storage shell 2. When it is necessary to weld the tungsten needle and the tungsten wire, the first electric cylinder 24 is opened, the first electric cylinder 24 drives the piston rod to move, and the piston rod drives the pusher assembly 3 inside the storage shell 2 to move, thereby completing the push-out of the tungsten needle.

[0034] It should be noted that the top of the storage shell 2 is connected to the feed shell 22; tungsten needles are added into the storage shell 2 from the top of the feed shell 22, and the feed shell 22 can store multiple tungsten needles to facilitate subsequent continuous production.
