[0002] Electric wire refers to the conductor for transmitting electric energy, which is divided into bare wire, electromagnetic wire and insulated wire. Bare wire has no insulation layer, including copper, aluminum flat wire, overhead stranded wire and various profiles. It is mainly used for outdoor overhead and indoor bus and switch box. Electromagnetic wire is an insulated wire that generates a magnetic field or induces current in a magnetic field when energized. It is mainly used for motor and transformer winding and other related electromagnetic equipment. Its conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties.

[0019] like Figure 1-6As shown, in one embodiment, a wire connection device for electrical production is proposed, including a lower plate 1, a guide column 101 is installed on the upper end of the lower plate 1, an upper plate 102 is slidably connected on the circumferential surface of the guide column 101, and a positioning component 2 and a connecting component 3 are arranged on the surface of the upper plate 102 and the lower plate 1. The connecting component 3 includes a stripping mechanism 31 and a winding mechanism 32. The stripping mechanism 31 includes a slide groove 311, a slider 312, a clamping block 313, a threaded rod 316 and a first motor 317. The two sets of slide grooves 311 are respectively opened on the lower plate 1 and the upper plate The surface of the block 102, a pair of sliders 312 are respectively slidably connected in the slide grooves 311 at the corresponding positions, a pair of clamping blocks 313 are respectively installed on the surface of the sliders 312 at the corresponding positions, a second arc groove 314 is opened on the surface of the clamping block 313, and a plurality of threading needles 315 are arranged in the second arc groove 314, a pair of threaded rods 316 are respectively rotatably connected in the lower plate 1 and the upper plate 102, a pair of first motors 317 are respectively installed in the lower plate 1 and the upper plate 102, and the output end of the first motor 317 is fixedly connected to the threaded rod 316 at the corresponding position; The peeling mechanism 31 includes a lifting groove 321, a lifting block 322, a rotating frame 323, a semicircular block 324, a fixed block 325, a semi-toothed ring 327 and a spring 329. A pair of lifting grooves 321 are respectively provided on the surface of the lower plate 1 and the upper plate 102. A pair of lifting blocks 322 are slidably connected in the lifting grooves 321 at corresponding positions. A pair of rotating frames 323 are respectively installed on the surfaces of the lifting blocks 322 at corresponding positions. A pair of semicircular blocks 324 are respectively slidably connected in the rotating frames 323 at corresponding positions. A pair of fixed blocks 325 are respectively installed in the semicircular blocks 324 at corresponding positions. A third arc groove 326 is provided on the surface of the fixed blocks 325. Two groups of semi-toothed rings 327 are respectively installed on the circumferential surfaces of the semicircular blocks 324 at corresponding positions. A groove 328 is provided on the lower end surface of the lifting block 322. The springs 329 are all installed in the groove 328. The lifting blocks 322 are slidably connected to the sliders 312 at corresponding positions.

[0020] In actual application, the embodiment of the present invention is to place two wires 203 to be connected together in the positioning assembly 2, and then control the upper plate 102 to move downward, so that the positioning assembly 2 operates to clamp the rear end of the wire 203, so that the rear end of the wire 203 is clamped and fixed. At the same time, after the positioning assembly 2 is operated, the clamping block 313 will clamp the front end of the wire 203, and then the threading needle 315 in the second groove 328 will be inserted into the insulating protective sleeve outside the wire 203, and then the insulating rubber sleeve on the circumferential surface of the wire 203 is melted to partially melt it, and then the first motor 3 is controlled to rotate. When the first motor 317 is in operation, the first motor 317 will drive the threaded rod 316 to rotate, and the threaded rod 316 will drive the slider 312 to move forward, thereby driving the clamping block 313 to move forward. Under the cooperation of the clamping block 313 and the threading needle 315, the insulating protective sleeve on the outside of the wire 203 can be pulled off from the melted part, and then it will continue to be pulled forward to separate it from the wire 203, and finally the copper wire inside the wire 203 is exposed, thereby completing the effect of stripping the insulating protective sleeve on the outside of the wire 203. When the slider 312 moves forward, the slider 312 will gradually release the spring 329. The lifting block 322 is pressed, and the lifting block 322 is provided with an inclined surface on its surface. The lifting block 322 will rise upward as the slider 312 moves forward. When the slider 312 moves to the frontmost position, the lifting block 322 will be fully raised, so that the two semicircular blocks 324 are merged together, and the semi-toothed rings 327 installed on the circumferential surfaces of the semicircular blocks 324 are spliced ​​into a complete toothed ring, and the fixed block 325 will clamp the copper wire part exposed to the outside, and then by controlling the semicircular block 324 to rotate in the rotating frame 323, the fixed block 325 can be driven to rotate, so that the two copper wires are moved together. The upper plate 102 is controlled to rise and reset, and the connected wires 203 can be taken out. Then, the threaded rod 316 is controlled to reverse, driving the slider 312 to move forward and reset. At this time, under the action of the inclined surface on the surface of the lifting block 322, the slider 312 will gradually press the lifting block 322 to reset, thereby driving the semicircular block 324 and the fixed block 325 to reset. At this time, the device is reset as a whole, and other wires 203 can be put into it for winding and connection.

[0021] like Figure 5-7 As shown, as a preferred embodiment of the present invention, a second motor 3210 is installed in the lifting block 322, a driving shaft 3211 is installed at the output end of the second motor 3210, a gear 3212 is installed on the circumferential surface of the driving shaft 3211, and the gear 3212 is meshed with the half gear ring 327.

[0022] When the embodiment of the present invention is actually applied, by controlling the operation of the second motor 3210, the second motor 3210 will drive the driving shaft 3211 to rotate, the driving shaft 3211 will drive the gear 3212 to rotate, the gear 3212 will drive the spliced ​​half-toothed ring 327 to rotate, and then drive the spliced ​​semicircular block 324 to rotate in the rotating frame 323, thereby achieving the effect of controlling the winding connection of the two copper wires.

[0023] like Figure 1-3 As shown, as another preferred embodiment of the present invention, a support frame 4 and a cutter 401 are respectively installed at the front end of the slider 312, the cutter 401 is installed at the front end of the upper slider 312, the support frame 4 is installed at the front end of the lower slider 312, and the cutter 401 and the support frame 4 are slidably connected.

[0024] In actual application of the embodiment of the present invention, after the copper wire is placed in the clamping block 313 and the fixing block 325, as the upper plate 102 moves downward, the clamping block 313 and the fixing block 325 are combined to clamp the wire 203. At this time, the cutter 401 will descend, and with the cooperation of the support frame 4, the wire 203 that passes over the fixing block 325 will be cut off, and the wires 203 that are wound and connected together will be trimmed, so that the lengths of the wound parts of the two wires 203 are the same. After winding, the length of one copper wire will not protrude, thereby improving the effect of the subsequent winding connection between the wires 203.

[0025] like Fig.11 and 12 As shown, as another preferred embodiment of the present invention, the positioning assembly 2 includes a positioning block 201 and a first arc-shaped groove 202, a pair of positioning blocks 201 are respectively installed on the surface of the lower plate 1 and the upper plate 102, two groups of first arc-shaped grooves 202 are both opened on the surface of the positioning block 201, and the first arc-shaped groove 202 clamps the wire 203.

[0026] In actual application, the embodiment of the present invention is to place the wire 203 in the first arc-shaped groove 202, and then control the upper positioning block 201 to move downward, so that the wire 203 is clamped in the first arc-shaped groove 202. When the outer insulation layers of the two wires 203 are subsequently stripped and the copper wire is rotated and wound, the rear end of the wire 203 is fixed to prevent the wire 203 from loosening, thereby improving the stability of the winding connection of the wire 203.

[0027] like Figure 1-3 As shown, as another preferred embodiment of the present invention, a connecting frame 204 is installed on the upper end of the guide column 101, and an electric push rod 205 is installed on the upper end of the connecting frame 204. The output end of the electric push rod 205 is fixedly connected to the upper plate 102.

[0028] When the embodiment of the present invention is actually used, by controlling the operation of the electric push rod 205, and then with the cooperation of the guide column 101, the electric push rod 205 will drive the upper plate 102 to move downward, so that the clamping block 313 and the fixing block 325 clamp and fix the front and rear ends of the wire 203 respectively, and at the same time achieve the effect of cutting and trimming the two wires 203 neatly.

[0029] like Fig. 9 As shown, as another preferred embodiment of the present invention, both the upper plate 102 and the lower plate 1 are provided with mounting grooves 206 , and both the mounting grooves 206 are provided with semicircular electric heating rings 207 .

[0030] In actual application of the embodiment of the present invention, after the two wires 203 are clamped and fixed in the second arc groove 314 opened on the surface of the clamping block 313, the semicircular electric heating ring 207 is controlled to heat and locally heat the insulating protective cover on the wire 203, causing it to melt and soften locally. At this time, by pulling the front end of the insulating protective cover forward, the insulating protective cover at the front end of the wire 203 can be peeled off, exposing the copper wire to the outside.

[0031] like Figure 8 and 9 As shown, as another preferred embodiment of the present invention, a plurality of anti-slip strips 5 are disposed in the first arc groove 202 and the third arc groove 326, and the anti-slip strips 5 are made of rubber.

[0032] In actual application, the embodiment of the present invention is provided with a plurality of anti-slip strips 5 in the first arc groove 202 and the third arc groove 326, so that the stability when clamping the electric wire 203 can be improved, and the insulating protective layer and the copper wire part can be stably clamped. When winding and connecting, since the length of the copper wire will gradually shorten during winding, and the front end of the copper wire has a contraction distance, the copper wires can be always clamped in the fixed block 325 during winding and connecting. During the winding process, the copper wire can be forced to slide between the protective strips provided in the third arc groove 326. The reason for the forced sliding is that the two fixed blocks 325 are pushed together by multiple springs 329 in the upper and lower directions to clamp the copper wire. The force of the fixed blocks 325 to merge is less than the force of the electric push rod 205 to push the positioning block 201, and then the fixed block 325 will be loosened to a certain extent when the twisted copper wire is wound, so that the copper wire retracts therein, and the rear end of the electric wire 203 always remains motionless, so that the two electric wires 203 can be stably wound and connected together.

[0033] like Fig.10 As shown, as another preferred embodiment of the present invention, the positioning block 201, the clamping block 313 and the fixing block 325 are respectively installed on the upper plate 102, the lower plate 1, the clamping block 313 and the fixing block 325 by bolts, and the positioning block 201, the clamping block 313 and the fixing block 325 are replaceable.

[0034] When the embodiment of the present invention is actually used, since the positioning block 201, the clamping block 313 and the fixing block 325 are all installed and positioned by bolts, they can be disassembled and replaced. The first arc groove 202, the second arc groove 314 and the third arc groove 326 in the positioning blocks 201, the clamping block 313 and the fixing block 325 of different sizes are different in size. The positioning block 201, the clamping block 313 and the fixing block 325 adapted thereto can be replaced according to the size of the wire 203, thereby achieving the effect of connecting and processing wires 203 of different diameters.
