The first feeding support and the second feeding support are symmetrically arranged at both ends of the hopper support. The second elastic element elastically connects the hopper support and the second feeding support and is used to push the second feeding support to abut the welding wire so that the welding wire is close to the guide roller.

[0017] In one embodiment, both the first pusher support and the second pusher support are slidably disposed on the hopper bracket, so that the first pusher support and the second pusher support can move along the stacking direction of the plurality of welding wires to abut the plurality of welding wires against the feeding roller and the plurality of guiding rollers; and / or,

[0018] The first pusher support is provided with a first hand-held part exposed outside the hopper support, and the second pusher support is provided with a second hand-held part exposed outside the hopper support. The first hand-held part and the second hand-held part are pressed together.

[0041] This embodiment of the invention provides a wire feeding mechanism, primarily used in welding torches, to feed welding wire and improve welding efficiency. Please refer to... Figures 1 to 6 One embodiment of the wire feeding mechanism includes a main support 100, a hopper module 200, and a drive module 300. The hopper module 200 is detachably mounted on the main support 100. A solder hopper 201 is provided inside the hopper module 200, and several welding wires 10 are stacked inside the solder hopper 201. The drive module 300 is mounted on the main support 100 and is used to feed the several welding wires 10 out in sequence. With this configuration, the wire feeding mechanism is small in size, and after being mounted on the welding gun, the welding gun has high portability and good welding flexibility.

[0042] Understandably, since the hopper module 200 is detachably mounted on the main support 100, when the welding wire 10 in the solder hopper 201 is used up or needs to be replaced with another type of welding wire 10, the hopper module 200 can be removed from the main support 100. This facilitates filling or replacing the welding wire 10 in the solder hopper 201, or directly replacing a hopper module 200 that is fully loaded with welding wire 10, thereby further improving the filling and replacement efficiency of the welding wire 10. Because the hopper module 200 in the wire feeding mechanism of this embodiment is easy to disassemble, it facilitates the maintenance of the wire feeding mechanism.

[0043] In one embodiment, please refer to Figures 1 to 6 The drive module 300 includes a drive motor 310 and a feeding roller 320. The drive motor 310 is connected to the feeding roller 320 and is used to drive the feeding roller 320 to rotate. The rotation of the feeding roller 320 can drive the welding wire 10 that is in contact with it to output the feeding. During the rotation of the feeding roller 320, the welding wire 10 can be pushed to output the feeding according to the preset trajectory by friction.

[0044] Furthermore, in this embodiment, the drive module 300 also includes a reduction component 330, which is connected to the output shaft of the drive motor 310 and the feeding roller 320. It is used to reduce the rotational motion output by the drive motor 310 and transmit it to the feeding roller 320. By setting the reduction component 330, the rotational speed of the feeding roller 320 can be reduced and the torque of the feeding roller 320 can be increased, thereby achieving stable and reliable feeding of the welding wire 10.

[0045] Specifically, the reduction assembly 330 is either a gear reducer or a worm gear reducer. Worm gear reducers have a relatively compact mechanical structure, are lightweight, and are easy to install and use, making them particularly suitable for space-constrained applications.

[0046] In one embodiment, please refer to Figure 2 The wire feeding mechanism also includes a controller, which is electrically connected to the drive motor 310 and is used to control the output power of the drive motor 310 so that the feeding speed of the welding wire 10 varies between 0-10 mm / s, thereby controlling the feeding speed of the welding wire 10 of the feeding mechanism.

[0047] Specifically, the drive module 300 is fixed to the main support 100 by strapping, riveting, or adhesive, thereby realizing the installation of the drive module 300 on the main support 100. Of course, in other embodiments, the wire feeding mechanism also includes a fixing seat 500, and the drive motor 310 is mounted on the main support 100 through the fixing seat 500.

[0048] In one embodiment, please refer to Figures 1 to 3 The hopper module 200 includes a hopper support 210 and a pusher assembly 220 mounted on the hopper support 210. The pusher assembly 220 includes a first elastic member 221 and a first pusher support 222. The first elastic member 221 elastically connects the hopper support 210 and the first pusher support 222 and is used to push the first pusher support 222 to abut against the welding wire 10 so that the welding wire 10 is close to the feeding roller 320, thereby ensuring that there is sufficient friction between the feeding roller 320 and the welding wire 10, and ensuring stable and reliable output feeding of the welding wire 10.

[0049] By setting up the feeding component 220, the welding wire 10 can be automatically replenished at the outlet position of the welding hopper 201, which is beneficial for feeding coordination with the feeding roller 320.

[0050] In one embodiment, please refer to Figures 1 to 4The hopper module 200 also includes several guide rollers 230, which are rotatably mounted on the hopper support 210 and spaced apart along the extension trajectory of the welding wire 10, so that the welding wire 10 can slide and engage with the guide rollers 230. The pusher assembly 220 also includes a second elastic element 223 and a second pusher support 224. The first pusher support 222 and the second pusher support 224 are symmetrically arranged at both ends of the hopper support 210. The second elastic element 223 elastically connects the hopper support 210 and the second pusher support 224 and is used to push the second pusher support 224 to abut against the welding wire 10, so that the welding wire 10 is close to the guide rollers 230, thereby facilitating the smooth and continuous output of the welding wire 10 from the welding hopper 201.

[0051] Specifically, the first elastic element 221 and the second elastic element 223 can both be selected as springs, and a number of guide rollers 230 are distributed at intervals along the length direction of the outlet position of the solder bin 201. Further, there can be three guide rollers 230, namely the first roller, the second roller and the third roller, wherein the second roller is disposed between the first roller and the third roller, and is disposed closer to the bottom of the solder bin 201 than the first roller and the second roller.

[0052] In one embodiment, please refer to Figures 1 to 3 The first pusher support 222 and the second pusher support 224 are both slidably disposed on the hopper support 210 so that the first pusher support 222 and the second pusher support 224 can move along the stacking direction of the plurality of welding wires 10 so that the plurality of welding wires 10 abut against the feeding roller 320 and the plurality of guiding rollers 230.

[0053] In this embodiment, the first pusher support 222 is provided with a first hand-held part 225 exposed outside the material bin support 210, and the second pusher support 224 is provided with a second hand-held part 226 exposed outside the material bin support 210. The first hand-held part 225 and the second hand-held part 226 are pressed together. The first pusher support 222 and the second pusher support 224 move away from the feeding roller 320 and a plurality of guide rollers 230. The first elastic member 221 and the second elastic member 223 are elastically compressed, thereby facilitating the addition or replacement of welding wire 10 in the welding material bin 201.

[0054] In one embodiment, please refer to Figures 1 to 6 The main support 100 is provided with mounting holes 110. The wire feeding mechanism also includes mounting components 400. Several mounting components 400 pass through the mounting holes 110 and are detachably connected to the hopper module 200 to detachably install the hopper module 200 onto the main support 100. There are two mounting holes 110, located at both ends of the main support 100. There are two mounting components 400, each corresponding to one of the mounting holes 110, facilitating the assembly and disassembly of the hopper module 200. Specifically, the mounting component 400 can be a plunger pin.

[0055] Furthermore, in this embodiment, multiple hopper modules 200 are provided, and one of the hopper modules 200 is detachably mounted on the main support 100. By providing multiple hopper modules 200, a new hopper module 200 can be promptly replaced when the welding wire 10 in the hopper module 200 is exhausted, thereby improving welding efficiency. Also, when it is necessary to change the type of welding wire 10, a new hopper module 200 can be promptly replaced, thus ensuring that the wire feeding type matches the welding requirements.

[0056] Specifically, the welding wire 10 stacked inside the welding hopper 201 can be copper welding wire, aluminum welding wire, stainless steel welding wire or carbon steel welding wire, etc. The diameter of the welding wire 10 can be selected from 0.8mm to 1.6mm. Further, the diameter of the welding wire 10 can be selected from 0.8mm, 1.0mm, 1.2mm or 1.6mm.

[0057] It is understood that the solder bin 201 is a storage space formed by the first pusher support 222, the second pusher support 224 and a number of guide rollers 230, and both the first pusher support 222 and the second pusher support 224 are provided with arc-shaped surfaces or horizontal surfaces that are adapted to the shape of the welding wire 10.

[0058] In one embodiment, please refer to Figures 1 to 6 The main support 100 is provided with a wire feeding hole 120, which is used to guide the output feeding of the welding wire 10, thereby facilitating the guiding and feeding of the welding wire 10. Furthermore, the feeding roller 320 is positioned close to the wire feeding hole 120.

[0059] Specifically, the main support 100 has an opening 130 for exposing the hopper module 200, which facilitates observation of the welding wire 10 inside the hopper module 200 through the opening 130, and allows for cleaning and straightening of the welding wire 10 through the opening to prevent foreign objects from getting stuck in the wire.

[0060] This utility model embodiment also provides a laser welding gun, which includes a gun body, an adapter, and a wire feeding mechanism. The adapter is detachably connected to the gun body and the wire feeding mechanism and is used to adjust the wire feeding angle of the wire feeding mechanism. The wire feeding mechanism is any of the wire feeding mechanisms described in the above embodiments.

[0061] Understandably, the small size of the wire feeding mechanism, when applied to a laser welding gun, enhances the gun's portability and welding flexibility. Furthermore, the adapter detachably connects the gun body and the wire feeding mechanism and allows for adjustment of the wire feeding angle, enabling the adjustment of the wire feeding angle according to different gun body structures, thus providing high adaptability to various gun bodies.

[0062] The adapter device of this embodiment can be used to adapt the wire feeding mechanism to gun bodies of different sizes and structures, thereby reducing the research and development costs of different wire feeding mechanisms.
