[0029] Example

[0030] like Figure 1 As shown, the utility model proposes a wire feeding device for a welding robot, comprising: a support frame 1 for support, and support legs are fixedly provided at the four corners of the bottom surface of the support frame 1, and through slots 2 are respectively opened on both sides of the support frame 1, and a group of guide rollers 3 are rotatably provided inside the through slots 2, which can stably guide the welding wire and improve the stability of the welding wire transmission; a detection component 4 is arranged inside the support frame 1 for monitoring the bumps on the surface of the welding wire, and the two ends of the detection component 4 respectively pass through the support frame 1 and extend to be connected with a pressure controller 5; a support frame 6 is fixedly arranged on the top surface of the support frame 1, and a conveying component 7 for wire feeding is provided on the support frame 6; a cutting component 8 for cutting the welding wire is located between the support frames 6, which can process rusted bumps on the transmitted welding wire, improve the stability of the welding wire transmission, and improve the quality of the welding wire.

[0031] like Figure 1 and Figure 2 As shown, the detection component 4 includes a fixed block 41, a guide groove 42 is provided inside the fixed block 41, and two groups of mounting grooves 43 are provided on the inner wall of the guide groove 42. Guide rods 44 are fixedly provided inside the mounting grooves 43, and the outer wall of the guide rod 44 is movably sleeved with a sleeve block 45, which can stably guide the sleeve block 45. A transmission rod 46 is fixedly connected between the sleeve blocks 45, and the transmission rod 46 is slidably connected to the guide groove 42. One end of the transmission rod 46 is fixedly connected to a pressure block 47, and the pressure block 47 is an arc-shaped structure, which can fit the welding wire better. A spring 48 is sleeved on the outer wall of the guide rod 44, one end of the spring 48 is fixedly connected to the mounting groove 43, and the other end of the spring 48 is fixedly connected to the sleeve block 45, which can reset the pressure block 47 to avoid continuous monitoring of the surface of the welding wire.

[0032] like Figure 1 and Figure 3As shown, the conveying component 7 includes a motor 71 fixedly installed on one side of the support frame 6. The output end of the motor 71 is fixedly connected to a threaded rod 72, and the threaded rod 72 is rotatably arranged between the support frames 6 through bearings. A connecting frame 73 is threadedly sleeved on the outer wall of the threaded rod 72, and the connecting frame 73 is movably clamped with the support frame 6, which can limit the connecting frame 73 and make its horizontal movement more stable. A mounting frame 74 is fixedly arranged at the lower end of the connecting frame 73. First cylinders 75 are respectively fixedly installed on both sides of the mounting frame 74. The output ends of the first cylinders 75 penetrate through the mounting frame 74 and extend to be connected with clamping blocks 76, which can stably clamp and convey the welding wire and ensure the welding efficiency.

[0033] As Figure 1 and Figure 4 As shown, the cutting component 8 includes a bracket 81 fixedly arranged between the support frames 6. Cutting through grooves 82 are respectively opened on both sides of the bracket 81 to facilitate the guiding of the welding wire. A second cylinder 83 is fixedly installed on one side of the bracket 81, and the second cylinder 83 is electrically connected to the pressure controller 5 to facilitate the transmission of electrical signals to control the switch of the second cylinder 83. The output end of the second cylinder 83 penetrates through the bracket 81 and extends to be connected with a transmission plate 84. Connecting blocks 85 are fixedly connected to both ends of the transmission plate 84. One end of the connecting block 85 is fixedly connected to a blade 86, and the connecting block 85 and the blade 86 are slidably connected with the cutting through groove 82, which can cut the welding wire into segments and thus avoid excessive waste of the welding wire.

[0034] Furthermore, a guiding groove 9 is opened on the inner bottom surface of the support frame 1, and the guiding groove 9 is inclined to facilitate the guiding and conveying of the cut welding wire.

[0035] Secondly, the inner ring surface of the pressing block 47 is concave to reduce the friction force in contact with the welding wire.

[0036] Furthermore, the pressure controller 5, the connecting frame 73, the mounting frame 74 and the bracket 81 are arranged in a "U" - shaped structure, which has stable support.

[0037] The working principle of this embodiment is as follows: First, the welding wire is sequentially passed through between the guiding roller 3, the pressing block 47, the clamping block 76 and the cutting through groove 82 to stably convey the welding wire. During the conveying process, when there are rust bumps on the surface of the welding wire, the bumps will push the pressing block 47 to move. The pressing block 47 drives the transmission rod 46 to move in the guiding through groove 42. One end of the transmission rod 46 pushes the pressure controller 5 and starts the pressure controller 5, so that the pressure controller 5 transmits an electrical signal to the second cylinder 83. At this time, the welding wire continues to be conveyed forward between the brackets 81. At the same time, the transmission rod 46 also drives the sleeve block 45 to vertically slide on the outer wall of the guiding rod 44. The sleeve block 45 pushes the spring 48 to contract, and the elastic force of the spring 48 can reset the pressing block 47, avoiding always fitting with the outer wall of the welding wire and improving the accuracy of the welding wire monitoring.

[0038] Furthermore, after the pressure controller 5 transmits an electrical signal to the second cylinder 83, the output end of the second cylinder 83 pushes the transmission plate 84 to move horizontally, and the transmission plate 84 drives the blade 86 to move horizontally in the cutting groove 82 through the connecting block 85, thereby cutting both ends of the welding wire with rusty bumps. The cut welding wire falls into the guide groove 9 and is guided and slid down through the guide groove 9 for centralized collection.

[0039] Furthermore, the cut welding wire continues to be transported forward, and after being transported between the clamping blocks 76, the clamping block 76 is pushed to stably clamp one end of the welding wire by starting the first cylinder 75, and then the motor 71 is started to drive the threaded rod 72 to rotate, and the threaded rod 72 drives the connecting frame 73 to move horizontally. The connecting frame 73 drives the clamping block 76 to move the welding wire stably clamped horizontally through the mounting frame 74, and one end of the welding wire passes through the guide rollers 3, so that the welding wire continues to be transported, and the rust on the surface of the welding wire can be cut, thereby removing the bumps on the surface of the welding wire, ensuring the stable transportation of the welding wire, and improving the welding quality.

[0040] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
