[0001] The utility model relates to the technical field of welding, in particular to an automatic wire feeding device for welding wire. Background Art

[0002] In the welding process, it is found that the welding wire is not round, and the deformed welding wire has an adverse effect on the clamping of the welding wire on the robotic arm; moreover, for robotic arm welding, the consumption of the welding wire needs to be estimated in advance and confirmed before each welding. Otherwise, it is easy to cause the situation that the welding wire has been consumed but not supplied in time during the welding process. Therefore, it is necessary to propose an automatic wire feeding device for welding wire to supply the welding wire, give an early warning when the welding wire is almost consumed, and remind the staff to perform the operation of replenishing the wire to avoid the situation that the welding wire is consumed during the welding process but the welding is still in progress.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-3 shown, the present utility model provides a technical solution: including a support assembly 1, a wire welding reel assembly 2 is arranged at the top of the front surface of the support assembly 1, and a warning assembly 3 is fixedly installed on the top surface of the support assembly 1;

[0020] The support assembly 1 includes a vertical plate 101, a rotating motor 104 is fixedly embedded at the top of the front surface of the vertical plate 101, and a rotating roller 105 is fixedly installed at one end of the output shaft of the rotating motor 104;

[0021] The warning assembly 3 includes a vertical plate 301, a top plate 302 is fixedly installed on the top surface of the vertical plate 301, a baffle 303 is fixedly installed at the front end of the bottom surface of the top plate 302, a round shaft 304 is fixedly installed between the back surface of the baffle 303 and the front surface of the vertical plate 301, a slider 305 is slidably sleeved on the round shaft 304, a spring 306 is sleeved on the rear end of the shaft body of the round shaft 304, and two ends of the spring 306 are respectively fixedly connected with the front surface of the vertical plate 301 and the back surface of the slider 305. A pressing head 307 is fixedly installed at the bottom of the front surface of the slider 305, a transmission rod 308 is rotatably connected to the bottom surface of the slider 305, a vertical groove 309 is formed on the front surface of the vertical plate 301, an L-shaped sliding rod 310 is slidably installed on the front surface of the vertical groove 309, a resisting plate 311 is fixedly installed at one end of the L-shaped sliding rod 310 away from the vertical plate 301, the bottom end of the transmission rod 308 is rotatably connected to the top surface of the resisting plate 311, a warning buzzer 312 is fixedly embedded at the bottom of the front surface of the baffle 303, and the vertical plate 301 is fixedly installed on the top surface of the vertical plate 101.

[0022] In this embodiment, a L-shaped support rod 102 is fixedly installed at the top of one side surface of the vertical plate 101. One end of the L-shaped support rod 102 is fixedly installed with a wire passing block 103. The wire reel assembly 2 includes a winding reel 201. A wire reel 202 is sleeved on the cylinder body of the winding reel 201. The winding reel 201 is sleeved on the rotating roller 105. A locking nut 106 is threadedly sleeved at one end of the rotating roller 105 away from the rotating motor 104. The back surface of the locking nut 106 is in contact with the front surface of the winding reel 201. One end of the welding wire can be passed through the wire passing opening formed in the wire passing block 103. After passing through, start the rotating motor 104 to drive the rotating roller 105 to rotate. The rotation of the rotating roller 105 can make the winding reel 201 rotate. The rotation of the winding reel 201 can send the welding wire of the wire reel 202 wound thereon to the processing end.

[0023] A switch button is arranged at one end of the warning buzzer 312 close to the pressing head 307. The pressing head 307 faces the switch button. When the amount of the welding wire of the wire reel 202 is reduced to a certain amount, at this time, the pressing head 307 will press the switch button of the warning buzzer 312. At this time, the warning buzzer 312 emits a beeping sound and flashes a light, so as to remind the staff that the wire reel 202 is about to run out, which can effectively avoid the situation that the amount of the welding wire is consumed during the welding process, but the welding is still in progress.

[0024] The bottom surface of the pressing plate 311 is in contact with the surface of the wire reel 202. Both sides of the bottom surface of the pressing plate 311 are provided with arc-shaped round corners, which can prevent the situation that the bottom surface of the wire reel 202 is scratched by the bottom surface of the pressing plate 311 during the rotation process, resulting in damage to the welding wire.

[0025] During use, one end of the welding wire can be passed through the wire passing opening formed in the wire passing block 103. After passing through, start the rotating motor 104 to drive the rotating roller 105 to rotate. The rotation of the rotating roller 105 can make the winding reel 201 rotate. The rotation of the winding reel 201 can send the welding wire of the wire reel 202 wound thereon to the processing end.

[0026] As the welding wire is consumed, the thickness of the welding wire reel 202 will become smaller and smaller. The bottom surface of the abutment plate 311 will always be in contact with the surface of the welding wire reel 202. Therefore, as the welding wire reel 202 becomes less and less, the abutment plate 311 will also descend accordingly. The bottom surface of the abutment plate 311 always contacts the surface of the welding wire reel 202. As the welding wire reel 202 is used, when its quantity decreases to a certain amount, at this time, the abutment plate 311 also descends to a certain height. During its descent, it will drive the bottom end of the transmission rod 308 to descend. During the descent of the transmission rod 308, under the action of the spring 306, the slider 305 will slide forward. The movement of the slider 305 can drive the pressing head 307 to move. When the quantity of the welding wire on the welding wire reel 202 decreases to a certain amount, at this time, the pressing head 307 will press the switch button of the warning buzzer 312. At this time, the warning buzzer 312 will emit a beeping sound and flash a light, so as to remind the staff that the welding wire reel 202 is about to run out, which can effectively avoid the situation that the welding wire is consumed completely during the welding process, but the welding is still in progress.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
