[0057] Existing technologies typically repair broken cables using fusion splicing. Fusion splicing offers advantages such as safety, reliability, and long service life. Currently, the process involves manually peeling away the outer insulation layer of the cable to expose the conductors. Two molds are then manually moved to clamp the two cables, and a fusion flux is added. The flux is then heated to connect the two conductors. Excess material at the weld is then manually cut and polished, and finally, external insulation tape is continuously wrapped around the weld. This process requires multiple people working together, making it time-consuming and labor-intensive. The cable repair device described in this embodiment can be applied to cable repair without requiring a large number of maintenance personnel, thus reducing unnecessary labor input, accelerating the repair process, and shortening the cable repair cycle.

[0058] like Figures 1 to 5 As shown, this embodiment provides a cable repair device, including a base 11, a wire stripping mechanism 12, a welding mechanism 13, and a cutting and grinding mechanism 14.

[0059] The base 11 is placed on the ground to support the wire stripping mechanism 12, the welding mechanism 13, and the cutting and grinding mechanism 14. The wire stripping mechanism 12, the welding mechanism 13, and the cutting and grinding mechanism 14 are all mounted on the base 11.

[0060] The wire stripping mechanism 12 is used to strip the insulation layer of the cable to expose the wire cores. The welding mechanism 13 is used to weld the two wire cores together. The cutting and grinding mechanism 14 is used to cut off excess material at the welding area and grind the welding area. The wire stripping mechanism 12 enables automatic wire stripping, eliminating the need for manual stripping with tools, thus reducing the labor intensity and manpower required for wire stripping. The welding mechanism 13 enables rapid cable welding. The cutting and grinding mechanism 14 automatically cuts and grinds off excess material at the welding area, fusing the two wire cores into a single wire with a circular outer surface, facilitating subsequent insulation layer application.

[0061] The welding mechanism 13 includes a first mold 131 having a first wire hole 133 and a second mold 132 having a second wire hole 134. The first mold 131 and the second mold 132 together enclose to form a flux tank 135, the first wire hole 133, and the second wire hole 134.

[0062] Specifically, the first mold 131 has a first wire clamping groove 1311 and a second wire clamping groove 1312, and the second mold 132 has a third wire clamping groove 1321 and a fourth wire clamping groove 1322. When the first mold 131 and the second mold 132 are engaged, the inner walls of the first wire clamping groove 1311 and the third wire clamping groove 1321 together form a first wire hole 133, and the inner walls of the second wire clamping groove 1312 and the fourth wire clamping groove 1322 together form a second wire hole 134. Both the first mold 131 and the second mold 132 also have semi-circular grooves, and the inner walls of the two semi-circular grooves together form a flux bath 135.

[0063] The flux tank 135 is located between the first wire hole 133 and the second wire hole 134, and both the first wire hole 133 and the second wire hole 134 are connected to the flux tank 135. The flux tank 135 extends from top to bottom, and both the first wire hole 133 and the second wire hole 134 extend horizontally. The upper end of the flux tank 135 has an opening, and the lower end of the upper end of the flux tank 135 is connected to both the first wire hole 133 and the second wire hole 134. The openings of the first wire hole 133 and the second wire hole 134 face opposite directions.

[0064] When repairing two broken cables, the cable repair device first uses a stripping mechanism 12 to strip the insulation layer from the connection ends of the two cables, and then uses a welding mechanism 13 to weld them together. The welding mechanism 13 uses a first mold 131 and a second mold 132 to clamp the two cables, so that the connection end of one cable extends into the flux tank 135 through the first wire hole 133, and the connection end of the other cable extends into the flux tank 135 through the second wire hole 134. Welding or welding flux is then added to the flux tank 135. The flux can be copper oxide powder and highly reactive aluminum. A welding torch ignites the copper oxide powder and highly reactive aluminum, generating heat to weld the two cables together. After the two cables cool, some of the flux forms solid waste at the weld area. A cutting and grinding mechanism 14 cuts and grinds the weld area to make its cross-section circular. Finally, an insulation layer is applied to the weld area to complete the cable repair. The wire stripping mechanism 12 can automatically strip the insulation layer, the welding mechanism 13 is simple to operate and has high welding efficiency, and the cutting and grinding mechanism 14 can automatically complete the cutting and grinding. Compared with the current stage where all repair processes are carried out manually step by step, the cable repair device in this embodiment is more efficient in repairing cables, does not require too much manpower, and reduces the workload of cable repair.

[0065] Optionally, a robotic arm is provided on the base 11, on which a welding gun and an injection machine for adding welding flux to the flux tank 135 are mounted, making the operation of the welding mechanism 13 simpler and further reducing the workload of cable repair.

[0066] In one embodiment, the first mold 131 and the second mold 132 together form a cable repair groove 136. Specifically, both the first mold 131 and the second mold 132 are provided with square grooves, and the inner walls of the two square grooves together form the cable repair groove 136. The cable repair groove 136 is used to place additional extension cables. Currently, some cables already in use have relatively fixed lengths. When a cable is damaged, for example, if one section is damaged, if fusion splicing is used for repair, the damaged part needs to be removed. After removal, the length is insufficient, and the two sections of cable cannot be connected. The entire cable must be replaced, which is not only costly, but also very difficult, time-consuming, and labor-intensive when the cable laying area is large and the laying location is difficult to disassemble. To solve the above problems, the cable repair device of this embodiment is provided with a cable repair groove 136, which can add an additional extension cable to fuse two cables that need to be fused. When the extension cable is fused, both ends of the extension cable are simultaneously fused with the two cables that need to be fused, which is highly efficient.

[0067] When it is necessary to extend the cable to weld two cables that need to be spliced, two flux tanks 135 are required. One flux tank 135 is used to weld one end of the extension cable to one of the cables to be spliced, and the other flux tank 135 is used to weld the other end of the extension cable to the other cable to be spliced. The two flux tanks 135 are spaced apart between the first wire hole 133 and the second wire hole 134. One flux tank 135 is connected to the first wire hole 133, and the other flux tank 135 is connected to the second wire hole 134. A filler groove 136 is located between the two flux tanks 135, and both flux tanks 135 are connected to the filler groove 136. In use, the extension cable is placed in the repair groove 136, one end of the extension cable is inserted into one of the flux grooves 135, and the other end of the extension cable is inserted into the other flux groove 135. After the flux is put into the two flux grooves 135, the flux is ignited so that the two ends of the extension cable are connected to the two cables respectively, so that the two cables are connected and the repair is completed.

[0068] Optionally, a cable winder 137 for cable positioning is provided on the inner wall of the cable replenishment groove 136. The cable winder 137 can be used to wind up the extension cable, thereby achieving cable positioning and reducing the size of the cable replenishment groove 136, which in turn makes the first mold 131 and the second mold 132 smaller.

[0069] Furthermore, the wire winder 137 includes a first slider 1371, a second slider 1372, a first rod 1373 mounted on the first slider 1371, and a second rod 1374 mounted on the second slider 1372. The first slider 1371 is mounted on the first mold 131, and the second slider 1372 is mounted on the second mold 132. When the first mold 131 and the second mold 132 abut and enclose to form a wire filling groove 136, the first rod 1373 and the second rod 1374 are both located within the wire filling groove 136 and are on the same straight line. In use, before the first mold 131 and the second mold 132 approach and abut each other, a portion of the extension cable is wound around the first rod 1373 with one end placed in the first clamping groove 1311 or the third clamping groove 1321, and the remaining portion of the extension cable is wound around the second rod 1374 with the other end placed in the second clamping groove 1312 or the fourth clamping groove 1322. Then, the first mold 131 and the second mold 132 approach and cooperate with each other, and finally, the welding mechanism 13 completes the cable repair. After the repair is completed, when the first mold 131 and the second mold separate, the first rod 1373 and the second rod 1374 separate, and the extension cable wound around the first rod 1373 and the second rod 1374 automatically detaches from the first rod 1373 and the second rod 1374, allowing the extension cable to be freely stretched into a straight state.

[0070] Optionally, the first rod 1373 is provided with a locking plate 1375, and the second rod 1374 is provided with a locking hole 1376 for the locking plate 1375 to be engaged. When the wire winder 137 is installed, after the first mold 131 and the second mold 132 abut and surround to form the wire filling groove 136, the locking hole 1376 into which the locking plate 1375 is engaged completes the positioning and connection of the first rod 1373 and the second rod 1374.

[0071] Furthermore, the first mold 131 is provided with a first groove 1361, and the second mold 132 is provided with a second groove 1362. When the first mold 131 and the second mold 132 abut and enclose to form the wire filling groove 136, the first groove 1361 and the second groove 1362 are both located on the inner wall of the wire filling groove 136 and are arranged opposite to each other. The first slider 1371 slides in the first groove 1361 and is detachably connected to the first mold 131, and the second slider 1372 slides in the second groove 1362 and is detachably connected to the second mold 132. When using the cable winder 137, the first rod 1373 and the second rod 1374 can be positioned and connected by first inserting the clamping plate 1375 into the clamping hole 1376. Then, the extension cable is wound around the first rod 1373 and the second rod 1374. When the first mold 131 and the second mold 132 abut and surround to form the cable repair groove 136, the cable winder 137 is installed to complete the installation of the extension cable, which facilitates the subsequent repair of the broken cable.

[0072] In one embodiment, the welding mechanism 13 further includes a driver mounted on the base 11. The first mold 131 and the second mold 132 are both slidably mounted on the base 11, sliding linearly along the same straight line, allowing them to move closer or further apart. The first mold 131 and the second mold 132 each have a first position and a second position. The driver is drive-connected to the first mold 131 and the second mold 132 to switch between the first and second positions. The driver can be an instrument capable of linear motion, such as an electric telescopic device or a cylinder. When the first mold 131 and the second mold 132 are in the first position, the driver drives them to abut against each other and enclose to form a first wire hole 133, a second wire hole 134, and a flux tank 135, after which welding can be performed. After the welding is completed, the first mold 131 and the second mold 132 are switched to the second position. When the first mold 131 and the second mold 132 are in the second position, the driver drives the first mold 131 and the second mold 132 to move away from each other, so that the cable can be removed.

[0073] Optionally, the driver includes a first motor and a lead screw 138 driven by the first motor. The first motor is not shown in the figure. The lead screw 138 has a first threaded section and a second threaded section, with the threads of the first threaded section and the second threaded section being opposite. A first guide block 1313 is provided on the first mold 131, and a second guide block 1323 is provided on the second mold 132. The first guide block 1313 is mounted on the first threaded section through a first threaded groove 1314 or a threaded hole, and the second guide block 1323 is mounted on the first threaded section through a second threaded groove 1324 or a threaded hole, thereby allowing the first mold 131 and the second mold 132 to slide and switch between a first position and a second position.

[0074] Furthermore, the first mold 131 and the second mold 132 also have a third position. When the first mold 131 and the second mold 132 are in the third position, both the first mold 131 and the second mold 132 are detachably connected to the machine base 11. Specifically, the second position is located between the third position and the first position. The first guide block 1313 is provided with a first threaded groove 1314, and the second guide block 1323 is provided with a second threaded groove 1324. The machine base 111 has a trapezoidal groove 115 extending along the sliding direction of the first mold 131 and the second mold 132. The trapezoidal groove 115 has a trapezoidal cross-section perpendicular to the sliding direction of the first mold 131 and the second mold 132. The first guide block 1313 and the second guide block 1323 are also trapezoidal. Both ends of the trapezoidal groove 115 are provided with mounting grooves 117, which are rectangular grooves. When the first guide block 1313 and the second guide block 1323 are in the trapezoidal groove 115, they cannot be separated from the machine base 112. When the first guide block 1313 slides to the rectangular groove at one end of the trapezoidal groove 115, and the second guide block 1323 slides to the rectangular groove at the other end of the trapezoidal groove 115, the first mold 131 and the second mold 132 are in the third position. At this time, both the first guide block 1313 and the second guide block 1323 can be removed from the mounting groove 117. By setting the mounting groove 117, the first mold 131 and the second mold 132 can be replaced, thereby allowing the welding mechanism 13 to adapt to cables of different sizes and facilitating the cleaning of the first mold 131 and the second mold 132.

[0075] Optionally, the bottom wall of the trapezoidal groove 115 is provided with a clearance groove 116 to facilitate the installation of the lead screw 138.

[0076] Optionally, a sealing cover is provided on the machine base 112 of the base 11 to seal the welding mechanism 13 during welding. Specifically, an exhaust fan is installed on the machine base 112 of the base 11. The exhaust fan is connected to the sealing cover and can be used to remove the gas generated during welding to avoid air pollution.

[0077] like Figure 1 , Figures 6 to 8As shown, in one embodiment, the wire stripping mechanism 12 includes a stripping tube 121, a first blade holder 122 slidably disposed on the outer surface of the stripping tube 121, and a first blade 124 mounted on the first blade holder 122. The stripping tube 121 has a third wire hole 126 and a blade groove 127. The third wire hole 126 communicates with the outside of the stripping tube 121 through the blade groove 127. The first blade 124 extends into the third wire hole 126 through the blade groove 127. During wire stripping, one end of the cable is inserted into the third wire hole 126, and the insulation layer is cut by the relative movement between the cable and the first blade 124. Multiple stripping tubes 121 can be provided to achieve simultaneous stripping of the insulation layer of multiple cables.

[0078] Specifically, there are two stripper tubes 121. The two cables that need to be connected are inserted into the third wire hole 126 from opposite directions, so that the insulation layer can be cut and then stripped.

[0079] Optionally, the cable extends from one end of the stripping tube 121 into the third wire hole 126, and the first blade 124 is mounted on the other end of the stripping tube 121 through the first blade holder 122, and the cutting length is determined by the amount of cable extension.

[0080] Furthermore, in order to facilitate the separation of the insulation layer from the cable core, there are at least two first blade holders 122 and one-to-one corresponding first blades 124. The two first blades 124 are arranged at intervals along the stripping tube 121 or the circumference of the cable, so that the insulation layer can be divided into at least two arc strips.

[0081] In other embodiments, the first cutter holder 122 can also be slidably mounted, causing the first blade 124 to slide along the length of the cable to cut the insulation layer. After the cable extends from one end of the stripper tube 121 into the third wire hole 126 and is fixed in place, the cutting length is determined according to the sliding distance of the first cutter holder 122.

[0082] Optionally, the first blade 124 can be detached or slidably installed, thereby facilitating the replacement of the first blade 124 or changing the relative position of the first blade 124 and the first blade holder 122. This allows for changing the depth to which the blade of the first blade 124 is inserted into the third wire hole 126, enabling the cutting of insulation layers of different thicknesses and avoiding damage to the wire core or the inability to cut the insulation layer.

[0083] In one embodiment, to achieve automatic separation of the insulation layer from the cable core, the stripping mechanism 12 further includes a second blade holder 123 and a second blade 125 mounted on the second blade holder 123. Specifically, the stripping tube 121 is provided with an annular groove 128, which divides the stripping tube 121 into a first tube segment 1211 and a second tube segment 1212. The first blade holder 122 is located at one end of the second tube segment 1212 away from the first tube segment 1211, and the second blade holder 123 is located at the annular groove 128. By setting different lengths of the second tube segment 1212, the length of the insulation layer cut off can be changed. Therefore, the length of the second tube segment 1212 can be set according to the required length of the insulation layer to be cut. The second blade 125 extends from the annular groove 128 into the interior of the first pipe section 1211. By driving the second blade holder 123 to slide along the annular groove 128, the second blade 125 slides around the circumference of the cable and cuts the insulation layer, completing the circumferential cutting of the insulation layer. Then the cut insulation layer moves to the first blade 124, and the first blade 124 completes the axial cutting of the insulation layer. The insulation layer is divided into at least two parts. After the insulation layer moves to the outside of the second pipe section 1212, the insulation layer automatically separates from the wire core, completing the stripping of the insulation layer.

[0084] In order to drive the second cutter holder 123 to slide along the annular groove 128, in this embodiment, the wire stripping mechanism 12 also includes a second motor, and a gear is installed at the output end of the second motor. The second cutter holder 123 is slidably mounted on the first pipe segment 1211 and / or the second pipe segment 1212. The first pipe segment 1211 and / or the second pipe segment 1212 are rotatably mounted with an annular rack. The gear meshes with the annular rack. When the second motor is started, it drives the gear to rotate, thereby causing the annular rack to drive the second cutter holder 123 to slide along the annular groove 128. Finally, the second blade 125 separates the insulation layer at the point where the cable needs to be welded from the other insulation layers that need to be retained.

[0085] Furthermore, the second blade 125 is installed in the same way as the first blade 124, thus adapting to cables with different insulation thicknesses.

[0086] Optionally, the cutting edge of the second blade 125 is a circular arc blade 129, which can adapt to the curvature of the cable insulation layer and complete the accurate cutting of the insulation layer in one go.

[0087] like Figure 2As shown, in one embodiment, the cable repair device further includes a conductivity detection mechanism 15 mounted on the base 11. The conductivity detection mechanism 15 detects whether the repaired cable is conductive. Specifically, the conductivity detection mechanism 15 includes a test base 151, a first conductive pin 152, and a second conductive pin 153. The first conductive pin 152 and the second conductive pin 153 are used to conduct external circuits. The test base 151 has a test groove 154. The first conductive pin 152 and the second conductive pin 153 are spaced apart on the inner wall of the test groove 154. During testing, the repaired cable is inserted into the test groove 154, with the welded portion located between the first conductive pin 152 and the second conductive pin 153. Both the first conductive pin 152 and the second conductive pin 153 abut against the cable core. When the external circuit is conductive, it indicates that the repaired cable is conductive.

[0088] Optionally, the test slot 154 is provided with a first pinhole and a second pinhole. One end of the first conductive pin 152 is installed in the first pinhole via a first spring, and one end of the second conductive pin 153 is installed in the second pinhole via a second spring. Before the repaired cable is fully inserted into the test slot 154, it is disconnected from the external circuit under the action of the first spring and the second spring. After the cable is fully inserted into the test slot 154, the first conductive pin 152 and the second conductive pin 153 are squeezed, the depth of the first pinhole inserted into the first pinhole increases, the depth of the second pinhole inserted into the second pinhole increases, and the first conductive pin 152 and the second conductive pin 153 are connected to the external circuit.

[0089] like Figure 10 As shown, in one embodiment, an injection molding mechanism 16 is also included, through which an insulation layer is formed after the cable test is completed.

[0090] Specifically, the injection molding mechanism 16 includes a first injection molding seat 161. The first injection molding seat 161 has a first channel 162, a second channel 163, and a third channel 164 connected sequentially. The first injection molding seat 161 includes two semi-circular tubes, which are detachably connected to form the first channel 162, the second channel 163, and the third channel 164. The first channel 162 and the third channel 164 have the same diameter, both larger than the diameter of the second channel 163. Both ends of the second channel 163 have inclined inner walls or arc-shaped inner walls, such that the diameter of one end of the second channel 163 gradually increases along the direction closer to the first channel 162, and the diameter of the other end of the second channel 163 gradually increases along the direction closer to the third channel 164. The outer surface of the first injection molding seat 161 has an injection hole 165 communicating with the second channel 163. When the outer insulation layer of the repaired cable is injection molded, the welding part is located inside the second channel 163. Injection is performed through injection hole 165, and the plastic is allowed to cool and form an insulation layer. Thus, the insulation layer formed by injection molding within the second channel 163 is thinner than the original cable insulation layer, facilitating the subsequent winding of a more wear-resistant insulation material. After winding the more wear-resistant insulation material, the diameter of the weld joint is the same as the original cable diameter. The inclined or arc-shaped inner wall facilitates the positioning of the insulation material when winding it.

[0091] In other embodiments, before cable repair, cold shrink tubing or heat shrink tubing can be applied to both cables. After the two cables are fused together, the cold shrink tubing or heat shrink tubing is used to cover the fused area to form an insulating layer. The cold shrink tubing or heat shrink tubing can also cover the injection-molded insulating layer.

[0092] like Figure 1 , Figure 2 As shown, in one embodiment, the base 11 includes a bracket 111 and a machine platform 112 rotatably mounted on the bracket 111. A wire stripping mechanism 12, a welding mechanism 13, a cutting and grinding mechanism 14, and an injection molding mechanism 16 are sequentially and spaced apart along the circumferential axis of rotation of the machine platform 112. The injection molding mechanism 16 is not shown in the figure. The wire stripping mechanism 12, welding mechanism 13, and cutting and grinding mechanism 14 are arranged circumferentially along the machine platform 112, resulting in a more compact installation and a smaller overall size of the base 11, while also facilitating cable repair work. When the cable repair device is in operation, the wire stripping mechanism 12, welding mechanism 13, cutting and grinding mechanism 14, and injection molding mechanism 16 rotate sequentially to directly above the machine platform 112 for convenient sequential operation.

[0093] To facilitate the positioning of the machine tool 112, the base 11 also includes positioning pins. The positioning pins are not shown in the diagram. The bracket 111 has several first positioning holes 113, and the machine tool 112 has several second positioning holes 114. The first positioning holes 113 and second positioning holes 114 correspond one-to-one. The first positioning holes 113 are spaced apart circumferentially along the rotation axis of the machine tool 112, and the second positioning holes 114 are also spaced apart circumferentially along the rotation axis of the machine tool 112. After rotating the machine tool 112 so that the required mechanism is positioned directly above it, the positioning pins are engaged with the first positioning holes 113 and second positioning holes 114 to complete the positioning of the machine tool 112.

[0094] In one embodiment, the base 11 further includes lifting feet and casters. Neither the lifting feet nor the casters are shown in the diagram. Multiple lifting feet and casters are provided, with each lifting foot and caster spaced apart on the bracket 111. During transport, the lifting feet are raised so that the casters contact the ground, facilitating the movement and transport of the base 11. When repairing cables, the lifting feet are lowered to contact the ground, moving the casters away from the ground, allowing the base 11 to move or shake during cable repair.

[0095] In one embodiment, the cable repair device further includes a rotary-mounted cutter. The blade of the cutter extends in a straight line at an angle of 30 to 60 degrees to the cable extension direction. Before the insulation layer is peeled off and fused, the cutter cuts the cores of the cable that need to be fused, forming a beveled surface on the cores and increasing the fusion area of ​​the cores.

[0096] In one embodiment, the cutting and grinding mechanism 14 includes a guide rail 141 mounted on a machine base 112, a sliding frame 142 slidably mounted on the guide rail 141, a cutting wheel 143 rotatably mounted on the sliding frame 142, a third motor mounted on the sliding frame 142 and drivenly connected to the cutting wheel 143, a friction seat 144, a pressure seat 145, a lifter 146, a material clamping hole 147, a clamp 148, and a sliding table 149. The cutting wheel 143 is used to cut excess material at the welding area.

[0097] Specifically, the excess material at the welding point is cylindrical. The third motor, friction seat 144, lifting device 146, clamp 148, and sliding table 149 are all mounted on the machine base 112. There are two clamps 148, which are spaced apart. The machine base 112 has a material clamping hole 147 located between the two clamps 148. The sliding frame 142 drives the cutting wheel 143 to move between the two clamps 148. Both clamps 148 have clamping holes and include two detachably connected semi-circular tubes. The clamping holes are formed by the two semi-circular tubes enclosing each other. The clamping holes hold the cable to complete the positioning of the cable. The welding points of the two cables are located between the two clamps 148. The cutting wheel 143 is positioned below the clamping holes of the two clamps 148 and is tangential to the inner wall of the clamping holes. When cutting excess material at the weld joint, the excess material at the weld joint is inserted into the material clamping hole 147, driving the cutting wheel 143 to move and rotate to complete the cutting of the excess material at the weld joint. Compared with the traditional cutting method of manually handling the cutting equipment, the cutting of the present invention is easier and more efficient.

[0098] Two clamps 148 are slidably mounted on the machine base 112 via a sliding table 149. After cutting, the sliding table 149 is driven to slide, causing the cut cable to move between the friction seat 144 and the pressure seat 145. The friction seat 144 and the pressure seat 145 are then used to polish the cable. Compared to the traditional method of polishing by manually holding sandpaper, the polishing of this invention is easier and more efficient.

[0099] Furthermore, the friction seat 144 is slidably mounted on the machine base 112 along the arrangement direction of the two clamps 148. The pressure seat 145 is mounted above the friction seat 144 via a lifter 146, which can be a cylinder, hydraulic cylinder, electric telescopic device, etc. The lifter 146 is used to bring the pressure seat 145 close to or against the friction seat 144. Both the pressure seat 145 and the friction seat 144 are provided with semi-circular grooves, and the inner wall of the semi-circular groove of the friction seat 144 is lined with abrasive discs. When the lifter 146 drives the pressure seat 145 close to and abuts against the friction seat 144, it can squeeze the cable, so that the welded part on the cable can fully abut against the abrasive discs. Then, the back-and-forth sliding friction of the friction seat 144 against the cut welded part is used to achieve grinding.

[0100] This embodiment also provides a cable repair method. Based on the above-described cable repair device, the cable repair method includes the following steps:

[0101] S10: Place the two cables to be fused into the stripping mechanism 12. The stripping mechanism 12 strips the insulation layer from one end of the two cables to expose the wire core. The stripping mechanism 12 uses the second blade 125 and the first blade 124 to strip the insulation layer from one end of the two cables.

[0102] S20: The first mold 131 and the second mold 132 are assembled to form a flux tank 135. The core of one cable passes through the first wire hole 133 and extends into the flux tank 135, and the core of the other cable passes through the second wire hole 134 and extends into the flux tank 135. If the lengths of the two cables are insufficient to allow for welding, an extension cable is provided in the supplementary wire groove 136 to enable welding of the two cables.

[0103] S30: Add welding flux into the flux bath 135 and ignite the flux to weld the two wire cores together.

[0104] S40: Wait for the welded area to cool down, then start the cutting and grinding mechanism 14 to cut off excess material at the welded area and grind the welded area. Use the cutting wheel 143 to cut off the excess welded material, and then use the friction seat 144 to grind it, so that the welded area is smooth and even.

[0105] S50: An insulating layer is provided at the welded area. A continuity test can be performed before the insulating layer is provided.

[0106] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
