[0031] like Figure 1-10 As shown, in one embodiment, an automatic welding device for electrical equipment maintenance is proposed, including a lower plate 1 and a guide assembly 2 arranged in the lower plate 1, the lower plate 1 is connected to an upper plate 101 through the guide assembly 2, a positioning assembly 3 is arranged in the lower plate 1, the positioning assembly 3 is used to fix the copper opening nose, a welding assembly 4 is arranged in the upper plate 101, the welding assembly 4 includes a mounting plate 402, a welding head 403 and a wire feeding hole 404, a slide groove 401 is opened on the upper end surface of the upper plate 101, the mounting plate 402 is slidably connected in the slide groove 401, the welding head 403 is installed in the mounting plate 402, and the wire feeding hole 404 is opened in the mounting plate 402, and the wire feeding hole 404 is used to guide the welding wire.

[0032] The positioning assembly 3 includes a positioning protrusion 301, a first positioning frame 302, a second positioning frame 303, a first rack 304, a second rack 305, a gear 306 and a tension spring 307. The positioning protrusion 301 is installed on the upper surface of the lower plate 1. The first positioning frame 302 and the second positioning frame 303 are both slidably connected in the lower plate 1. The first rack 304 and the second rack 305 are respectively installed on the surfaces of the first positioning frame 302 and the second positioning frame 303. The gear 306 is rotatably connected in the lower plate 1 through a rotating shaft. The first rack 304 and the second rack 305 are both meshed with the gear 306. A tension spring 307 is installed between the first rack 304 and the second positioning frame 303, and between the second rack 305 and the first positioning frame 302.

[0033] In actual application of the embodiment of the present invention, the first positioning frame 302 and the second positioning frame 303 are pushed to move toward both sides, so that the position of the copper opening nose is opened by the lower plate 1, and then the copper opening nose is positioned under the action of the positioning protrusion 301, and then the tension spring 307 pulls the first positioning frame 302 and the second positioning frame 303 inward to move, thereby clamping and pressing down the two sides of the copper opening nose, so that the position of the copper opening nose is positioned, and under the action of the gear 306, the first rack 304 and the second rack 305, the first positioning frame 302 and the second positioning frame 303 can be made to move relative to each other at the same position, so that the copper opening nose can be clamped and positioned. Correction is performed to avoid the copper opening nose from tilting, and then the copper wire can be placed in the copper opening nose, and then the upper plate 101 is pressed down under the action of the guide component 2, so that the welding component 4 is close to the copper opening nose and the copper wire, and then the welding head 403 is controlled to open, and then the welding wire is conveyed under the guidance of the wire feeding hole 404, so that the welding wire is conveyed to the bottom of the welding head 403, and finally the welding wire is melted into liquid through the welding head 403 and penetrated into the space between the copper opening nose and the copper wire, and at the same time, the welding component 4 is controlled to slide in the slide groove 401, so that the liquid can move back and forth between the copper opening nose and the copper wire, so that the copper opening nose and the copper wire are welded evenly, and the stability after welding is improved, thereby completing the effect of automatic welding of the copper opening nose and the copper wire.

[0034] like Figure 4-6 As shown, as a preferred embodiment of the present invention, a release rod 308 is installed at the lower end of the first positioning frame 302 and the second positioning frame 303. The release rod 308 is slidably connected to the lower plate 1, and the release rods 308 slide relative to each other.

[0035] When the embodiment of the present invention is actually used, by pressing the release rod 308 inward, the first positioning frame 302 and the second positioning frame 303 can be pushed to move to both sides, so that the first positioning frame 302 and the second positioning frame 303 are in an open state. When the release rod 308 is released, the first positioning frame 302 and the second positioning frame 303 can be pulled inward by the action of the tension spring 307 to achieve a closed state, so that the copper opening nose can be quickly disassembled and assembled.

[0036] like Figure 1-3 As shown, as another preferred embodiment of the present invention, the guide assembly 2 includes a lower handle 201, an upper handle 202, a guide rod 204 and a spring 205. The lower handle 201 is installed on the surface of the lower plate 1. Guide holes 203 are provided in the lower handle 201 and the lower plate 1. The guide rod 204 is slidably connected in the guide hole 203. The upper handle 202 is installed on the surface of the upper plate 101. The guide rod 204 is installed on the lower ends of the upper plate 101 and the upper handle 202. Springs 205 are installed between the lower handle 201 and the lower plate 1 and the upper handle 202 and the upper plate 101.

[0037] When the embodiment of the present invention is actually used, by holding the upper handle 202 and the lower handle 201 by hand at the same time, the upper plate 101 and the lower plate 1 can be controlled to move closer together through the cooperation of the guide rod 204 and the guide hole 203, and then the welding assembly 4 can be controlled to approach the position of the copper opening nose to complete the subsequent welding operation. When the welding is completed, after loosening the upper handle 202 and the lower handle 201, the upper plate 101 can be pushed to reset under the action of the spring 205, so that the upper plate 101 and the lower plate 1 are unfolded, which is convenient for taking out the copper opening nose.

[0038] like Figure 1 and 11 As shown, as another preferred embodiment of the present invention, a locking mechanism 5 is provided in the lower plate 1 and the upper plate 101, and the locking mechanism 5 includes a movable groove 501, a locking frame 502 and a locking block 503. The movable groove 501 is provided in the lower plate 1, the locking frame 502 slides in the movable groove 501, and the locking block 503 is installed at both ends of the upper plate 101. The through hole 504 provided on the surface of the locking block 503 cooperates with the locking block 503.

[0039] In actual application of the embodiment of the present invention, after the upper plate 101 and the lower plate 1 are controlled to move together by hand, the locking frame 502 can be pushed to move in the movable groove 501 so that the locking block 503 is inserted into the through hole 504 opened on the surface of the locking frame 502, so that the current position of the upper plate 101 and the lower plate 1 can be locked. During welding, the hand does not need to exert force to keep the upper plate 101 and the lower plate 1 close together, making the equipment more labor-saving when used.

[0040] like Figure 1 and 3 As shown, as another preferred embodiment of the present invention, a pair of pressing blocks 6 are installed on the lower end surface of the upper plate 101, and the lower end surface of the pressing block 6 is provided with an inclined surface 601.

[0041] In actual application of the embodiment of the present invention, when the upper plate 101 and the lower plate 1 are controlled by hand to move closer, a pair of pressure blocks 6 installed at the lower end of the upper plate 101 will press down on both sides of the copper opening nose, causing the copper opening nose to deform inward, thereby wrapping the copper wire in the copper opening nose, achieving the effect of clamping the copper wire. After subsequent welding, the connection stability between the copper wire and the copper opening nose is improved.

[0042] like Figure 7-10 As shown, as another preferred embodiment of the present invention, a rotating frame 7, a guide frame 701 and a traction frame 702 are installed on the upper end of the mounting plate 402, a welding wire roller 703 is rotatably connected to the rotating frame 7 via a rotating shaft, a guide wheel 704 is rotatably connected to the guide frame 701 via a rotating shaft, a driving shaft 705 and a driven shaft 706 are rotatably connected to the traction frame 702, friction wheels 707 are installed on the circumferential surfaces of the driving shaft 705 and the driven shaft 706, the driving shaft 705 is connected to the output end of a micro motor 708 installed on the upper end of the mounting block, and the welding wire in the welding wire roller 703, one end away from the welding wire roller 703, passes through the wire feeding hole 404.

[0043] When the embodiment of the present invention is actually used, before the welding work starts, the welding wire on the welding wire roller 703 is passed around the guide wheel 704, then passed between the friction wheels 707, and finally passed through the wire feeding hole 404, and then the welding head 403 is controlled to open when the welding head 403 approaches the copper opening nose. At this time, the micro motor 708 is started synchronously, and the micro motor 708 will drive the drive shaft 705 to rotate, and then drive the friction wheel 707 to rotate relatively. Under the action of the friction wheel 707, the welding wire can be pulled for transportation, so that the welding wire is continuously melted by the welding head 403 and penetrates from the liquid into the gap between the copper opening nose and the copper wire, thereby achieving the effect of welding between the copper opening nose and the copper wire.

[0044] In one case of an embodiment of the present invention, a rubber layer is provided on the surface of the friction wheel 707. When the welding wire passes through the friction wheels 707, the rubber layer on its surface can have an effect of squeezing the welding wire, so that the friction wheel 707 has a higher friction force on the welding wire, thereby satisfying the function of conveying the welding wire.

[0045] like Figure 8 and 9As shown, as another preferred embodiment of the present invention, a driving motor 8 is installed in the upper plate 101, and a reciprocating screw 801 is installed at the output end of the driving motor 8. The reciprocating screw 801 is rotationally connected to the upper plate 101, and the reciprocating screw 801 is threadedly connected to the mounting plate 402.

[0046] When the embodiment of the present invention is actually applied, after the welding head 403 is turned on, the driving motor 8 runs synchronously. When the welding head 403 continues to melt the welding wire, the reciprocating screw rod 801 is driven by the driving motor 8 to rotate, so that the mounting plate 402 can be controlled to slide back and forth in the slide groove 401, thereby driving the welding head 403 to slide back and forth, so that the molten liquid of the welding wire is evenly melted in the copper opening nose, thereby improving the stability of the copper opening nose and the copper wire after welding.

[0047] like Figure 7 As shown, as another preferred embodiment of the present invention, an on / off button 802 is installed at the upper end of the upper handle 202, and the on / off button 802 is used to control the on / off of the welding head 403, the micro motor 708 and the drive motor 8, and a battery 803 is installed in the upper handle 202.

[0048] When the embodiment of the present invention is actually used, the opening and closing of the welding assembly 4 can be controlled by the opening and closing button 802 to complete the welding operation between the copper opening nose and the copper wire. At the same time, a battery 803 is arranged in the upper handle 202, which can supply power to the device without an external power supply during operation, thereby improving the convenience of using the device.

[0049] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
