DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0038] like Figures 1 to 15 As shown, the multi-core wire harness for an ultrasonic probe that is easy to weld described in this embodiment includes a wire harness 1, on which a wire stripping structure is provided; the number of wire stripping mechanisms can be set to multiple, and the multiple wire stripping mechanisms can be preset according to the actual length of the ultrasonic probe used.

[0039] Specifically, the wire stripping structure includes a first wire stripping mechanism 2 and two second wire stripping mechanisms 3 connected to both ends of the first wire stripping mechanism;

[0040] The first wire stripping mechanism includes a first shell 21 and two rotating seats 22, the first shell 21 is roughly tubular; the two rotating seats 22 are arranged at both ends of the first shell 21 for rotation at intervals; the two rotating seats 22 are symmetrically arranged; a locking pin 23 is connected between the two rotating seats 22; a cutting path 211 is provided on the outer wall of the first shell 21 in the middle of the corresponding locking pin 23, and the first shell 21 can be cut into two symmetrical sections by the cutting path 211; an elastic energy storage member 24 is provided between the rotating seat 22 and the first shell 21; the elastic energy storage member 24 is in an energy storage state at the initial time; the elastic energy storage member 24 is preferably a coil spring; a first cutting knife group is movably provided at one end of each rotating seat 22 away from the locking pin 23;

[0041] Annular grooves are provided in the first housing 21 at both ends of the corresponding locking pin 23. The projection of the cutting path 211 on the horizontal cross-section of the first housing 21 partially overlaps with the projection of the annular groove on the horizontal cross-section of the first housing 21. This allows the locking pin 23 to be released from the restriction of the first housing 21 when the first housing 21 is cut, allowing the locking pin 23 to slide in the annular groove after cutting.

[0042] The second wire stripping mechanism 3 includes a second shell 31, which is a rectangular parallelepiped with a hollow structure inside; one end of the second shell 31 is movably provided with two flattening rollers 32 facing each other up and down, and the other end is movably provided with two friction rollers 33 facing each other up and down; one end of the second shell 31 is also movably provided with two second cutting knife groups facing each other up and down; the two second cutting knife groups are respectively connected to the corresponding friction rollers 33 in transmission; the second shell 31 is also movably provided with a stripping component and two locking components for locking the second cutting knife groups; initially, the locking component locks the second cutting knife group; the two locking components are movably abutted against the stripping component; a first tension spring 37 is connected between the two locking components.

[0043] When the wiring harness 1 needs to be used, the cutting path 211 of the first shell 21 of the stripping structure at the preset length position is cut, so that the locking pin 23 is cut off, and the wiring harness 1 is divided into two sections. At this time, the cut locking pin 23 is not restricted by the locking of the first shell 21. At this time, the coil spring releases the stored energy, driving the corresponding rotating seat 22 to rotate, and the rotating seat 22 drives the first cutting knife group to rotate. The first cutting knife group performs a circular cut on the wiring harness 1 during the rotation process, thereby leaving a first incision on the first insulation layer of the wiring harness 1, exposing several wire cores; then, the wiring harness 1 is pulled out in a direction away from the cutting path 211, and the first insulation layer portion from the first incision to the incision position of the wiring harness 1 is stripped off and detached from the first shell 21;

[0044] like Figure 7As shown, when the exposed wire core moves between the two flattening rollers 32, the two flattening rollers 32 squeeze the wire core so that several wire cores are oriented and arranged horizontally to facilitate subsequent welding operations; then, as shown in FIG. Figure 7 As shown, when the first incision position of the wiring harness 1 comes to be opposite to the stripping assembly, the locking assembly releases the lock on the second cutting knife group. Then, while the wiring harness 1 is pulled outward, the wiring harness 1 drives the two friction rollers 33 to rotate through friction force, and the two friction rollers 33 synchronously drive the two second cutting knife groups to rotate. The two second cutting knife groups simultaneously cut a number of equally spaced second incisions on the second insulation layer of several horizontally arranged wire cores, which provides convenience for the subsequent removal of the second insulation layer and greatly improves the efficiency of wire stripping; when the wire core enters the stripping assembly, the stripping assembly strips the second insulation layer cut from each wire core from the wire core until the wiring harness 1 is pulled out from the second stripping mechanism 3, thereby realizing the stripping of the first insulation layer and the second insulation layer of the wiring harness 1 and the directional arrangement of the wire cores.

[0045] This embodiment pre-installs a wire stripping structure on the wire harness 1, which can efficiently and conveniently remove the insulation layer, improve wire stripping efficiency, reduce manual intervention, reduce labor intensity, and improve product consistency and stability; and by cutting multiple incisions on the wire core, when stripping the insulation layer, the multiple notches make the force more evenly distributed at different positions of the wire core, greatly reducing the risk of excessive local force on the wire core, deformation and breakage, effectively protecting the integrity and electrical performance of the wire core, and improving the reliability of the wire harness 1.

[0046] At the same time, multiple cuts can better destroy the adhesion between the insulation layer and the wire core, making the insulation layer smoother when peeling off and easier to completely peel off from the wire core, reducing the problem of insulation layer residue and providing a better wire core preparation state for subsequent welding.

[0047] like Figure 4 As shown, in some embodiments of the multi-core wire harness for an ultrasonic probe of this embodiment, a first cutting blade assembly includes a first cutter 251 movably mounted on the rotating base 22 along the radial direction of the rotating base 22. Preferably, the first cutter 251 is arc-shaped to better conform to the outer circumference of the wire harness 1. The first cutter 251 is provided with a cutter shaft 252 that movably extends through the rotating base 22. A spring 253 is sheathed on the outer wall of the cutter shaft 252. The ends of the spring 253 abut against the cutter shaft 252 and the rotating base 22, respectively. Preferably, a first retaining plate is provided at the end of the cutter shaft 252, and the spring 253 abuts against the first retaining plate. A driving groove 212 is provided on the inner wall of the first housing 21 at a position corresponding to the cutter shaft 252. The cutter shaft 252 is movably inserted into the driving groove 212. When the rotating base 22 drives the first cutter 251 to rotate, the driving groove 212 causes the first cutter 251 to extend toward the axis of the rotating base 22, overcoming the elastic force of the spring 253. Preferably, each rotating base 22 is provided with a plurality of first cutting blade assemblies evenly distributed along the circumference.

[0048] Specifically, after the locking pin 23 is cut off, the coil spring releases the stored energy and drives the rotating seat 22 to rotate relative to the first shell 21. The rotating seat 22 synchronously drives each first cutting knife group to rotate. When the first cutting knife group rotates relative to the first shell 21, the driving groove 212 squeezes the first tool 251 through the knife shaft 252, so that the first tool 251 overcomes the elastic force of the spring 253 and extends inward. The first tool 251 cuts into the first insulating layer until the knife shaft 252 moves out of the driving groove 212. At this time, the first tool 251 remains in an extended state, thereby cutting a first incision in the first insulating layer. As the wiring harness 1 is pulled out, the cut first insulating layer is detached from the wiring harness 1, thereby completing the stripping operation of the first insulating layer.

[0049] For example, Figure 5 As shown, the driving slot 212 includes a locking slot and an inclined slot; initially, the first clamping platform is accommodated in the locking slot under the elastic force of the spring 253, and when the rotating seat 22 drives the first tool 251 to rotate, the first clamping platform moves out of the locking slot to the inclined slot, so that the first shell 21 generates an extrusion force on the first tool 251, so that the first tool 251 extends radially inward to cut into the first insulating layer.

[0050] like Figure 8 and Figure 9 As shown, the ultrasonic probe of this embodiment uses a multi-core wire harness. In some embodiments, the second cutting knife group includes two oppositely arranged transmission wheels 341, two oppositely arranged eccentric wheels 342, a knife holder 343 connected between the two eccentric wheels 342, and a plurality of second knives 344 arranged at equal intervals on the knife holder 343; the transmission wheel 341 is rotatably arranged on the inner wall of the second shell 31; the transmission wheel 341 is transmission-connected to one end of the corresponding friction roller 33; the transmission wheel 341 is provided with an eccentric shaft; the eccentric wheel 342 is rotatably provided on the eccentric shaft; the outer peripheral wall of the transmission wheel 341 is provided with a locking notch 3411 for locking with the locking assembly; the outer peripheral wall of the eccentric wheel 342 is extended with an extension arm 3421, and a limit column 345 is movably provided on the extension arm 3421; one end of the limit column 345 is movably passed through the second shell 31.

[0051] Specifically, the friction roller 33 is connected to the transmission wheel 341 through a transmission belt; after the locking assembly is moved out of the locking notch 3411, the locking assembly releases the lock on the transmission wheel 341. At this time, the two friction rollers 33 can rotate during the movement of the wiring harness 1, and the friction roller 33 drives the transmission wheel 341 to rotate through the transmission belt, and the transmission wheel 341 drives the eccentric wheel 342 to rotate. Since the eccentric wheel 342 is eccentrically arranged and the eccentric wheel 342 is restricted by the limiting column 345, the eccentric wheel 342 drives the second tool 344 to rotate through the tool holder 343, so that a plurality of second incisions can be cut at equal intervals in the second insulation layer on the wire core. The plurality of second incisions can better destroy the adhesion between the second insulation layer and the wire core, making the second insulation layer smoother when detached and easier to completely peel off from the wire core, reducing the problem of residual second insulation layer, for subsequent welding operations.

[0052] like Figure 8 and Figure 10 As shown, in some embodiments of the multi-core wire harness for the ultrasonic probe of this embodiment, the locking assembly includes two spaced apart limit frames 361. Specifically, the two limit frames 361 are distributed on both sides of the second shell 31, and the two locking assemblies are symmetrically arranged up and down; the two ends of the first tension spring 37 are respectively connected to the limit frame 361 and the limit frame 361 corresponding to the other locking assembly; one end of the limit frame 361 is movably arranged on the inner wall of the second shell 31 and is used to cooperate with the locking notch 3411, and the other end of the limit frame 361 is movably abutted against the stripping assembly. Figure 7 、 Figure 8 、 Figures 10 to 15As shown, the multi-core wire harness for the ultrasonic probe of this embodiment, in some embodiments, the stripping assembly includes a stripping frame 351 arranged in the second shell 31, and the stripping frame 351 is movably provided with two driving sliders 352, two slide bars 353, two first clamping plates 354 and two second clamping plates 355 arranged opposite to each other in the upper and lower directions; each driving slider 352 is provided with a first inclined boss 3521 and a second inclined boss 3522 arranged in a staggered manner; the two opposite inner side walls of the stripping frame 351 are respectively provided with an L-shaped slide groove 3511 corresponding to each slide bar 353; the vertical section of the L-shaped slide groove 3511 is set away from the friction roller 33; the two ends of the slide bar 353 are respectively connected to the second shell 31 near the friction roller 33 One end of the wiping roller 33 is connected to a second tension spring 356; both ends of the slide rod 353 are movably embedded in the L-shaped slide groove 3511; each first clamping plate 354 is convexly provided with a third inclined boss 3541 for cooperating with the first inclined boss 3521; each second clamping plate 355 is convexly provided with a fourth inclined boss 3551 for cooperating with the second inclined boss 3522; the third inclined boss 3541 and the fourth inclined boss 3551 are staggered; both ends of the driving slider 352 are convexly provided with a first push portion 3523; both ends of the slide rod 353 are provided with a second push portion 3531 for cooperating with the first push portion 3523; the other end of the limit frame 361 is movably abutted against the corresponding slide rod 353.

[0053] Initially, one end of the limit frame 361 is embedded in the locking notch 3411, thereby locking the transmission wheel 341, and the slide rod 353 is located in the vertical section of the L-shaped slide groove 3511. At this time, the second tension spring 356 is in a stretched state, and the two slide rods 353 are respectively in contact with the outer peripheral wall of the wiring harness 1. Figure 13 As shown, the first inclined boss 3521 is in close contact with the corresponding third inclined boss 3541; when the first cutout of the wiring harness 1 comes under the slide bar 353, under the action of the first tension spring 37, the two upper and lower opposite limit frames 361 move toward each other, and at the same time, the two slide bars 353 also move toward each other, so that one end of the limit frame 361 moves out of the locking notch 3411, thereby releasing the lock on the transmission wheel 341, as shown in FIG. Figure 8 As shown, in this way, driven by the friction roller 33, the friction roller 33 drives the transmission wheel 341 to rotate through the transmission belt, the transmission wheel 341 drives the eccentric wheel 342 to rotate, and the eccentric wheel 342 drives the second cutter 344 to rotate through the tool holder 343, cutting a plurality of second incisions at equal intervals in the second insulation layer on the wire core; at the same time, the end of the slide bar 353 enters the horizontal section of the L-shaped slide groove 3511, and under the action of the second tension spring 356, the slide bar 353 slides along the horizontal section of the L-shaped slide groove 3511 toward the friction roller 33. When the second push rod of the slide bar 353 abuts against the first push portion 3523 of the driving slider 352, as shown in FIG. Figure 14As shown, the slide bar 353 pushes the driving slider 352 to slide synchronously, and the two driving sliders 352 respectively cooperate with the third inclined boss 3541 of the corresponding first clamping plate 354 through the first inclined boss 3521, so that the two first clamping plates 354 move toward each other, thereby clamping several horizontally arranged wire cores. As the wire harness 1 is continuously pulled, the two first clamping plates 354 cause part of the second insulation layer to separate from the wire core until the first inclined boss 3521 is out of contact with the third inclined boss 3541; as the driving slider 352 slides further, when the second inclined bosses 3522 of the two driving sliders 352 are in contact with the fourth inclined boss 3551 on the corresponding second clamping plate 355, as shown Figure 15 As shown, the two driving sliders 352 cause the two second clamps 355 to move toward each other, thereby clamping several wire cores to peel off the second insulation layer from the wire cores; in this way, through the secondary peeling method, the risk of excessive local force, deformation and breakage of the wire cores is reduced, the integrity and electrical performance of the wire cores are effectively protected, the quality and reliability of the wiring harness 1 are improved, and the second insulation layer is easier to be completely pulled out from the wire core, reducing the problem of residual second insulation layer.

[0054] like Figure 11 and Figure 12 As shown, in some embodiments of the multi-core wire harness for an ultrasonic probe of this embodiment, two pairs of mounting posts extend from the top and bottom walls of the stripping frame 351, respectively. Each mounting post is provided with a guide slot. Both ends of the first clamping plate 354 and the second clamping plate 355 are elastically and floatingly provided with latches, which are movably embedded in the guide slots. Specifically, the guide slot includes a first locking slot, an inclined slot, a vertical slot, and a second locking slot, which are sequentially connected. The first locking slot is provided at the end away from the axis of the wire harness 1. Initially, the latch is located in the first locking slot. In this embodiment, mounting posts are provided to facilitate the installation of the first clamping plate 354 and the second clamping plate 355. When the driving slider 352 squeezes the first clamping plate 354 or the second clamping plate 355, the latch moves from the first locking slot into the inclined slot, then through the inclined slot into the vertical slot, and finally from the vertical slot into the second locking slot. At this point, the first clamping plate 354 or the second clamping plate 355 clamps the plurality of wire cores to strip the second insulation layer.

[0055] like Figure 9 As shown, in this embodiment of the multi-core wire harness for the ultrasonic probe, in some embodiments, the extension arm 3421 is provided with a strip-shaped hole; the other end of the limiting post 345 is movably engaged with the strip-shaped hole. Preferably, the other end of the limiting post 345 is provided with a second latch, which is movably engaged with the extension arm 3421. In this embodiment, the provision of the strip-shaped hole allows the limiting post 345 to adaptively move relative to the eccentric wheel 342 as the eccentric wheel 342 rotates.

[0056] like Figure 8As shown, in some embodiments of the multi-core wire harness for an ultrasonic probe of this embodiment, a first tensioning belt 38 is connected between two flattening rollers 32. Each flattening roller 32 has accommodating grooves uniformly distributed along its axial direction on its outer peripheral wall. In this embodiment, the first tensioning belt 38 is provided to tension the two flattening rollers 32, ensuring that the flattening rollers 32 effectively shape and align the wire cores. After the wire cores enter between the two flattening rollers 32, the flattening rollers 32 shape and align the wire cores, allowing them to fit into the accommodating grooves one by one, thereby ensuring a horizontal arrangement.

[0057] like Figure 8 As shown, in some embodiments of the multi-core wire harness for an ultrasonic probe of this embodiment, a second tensioning belt 39 is connected between the two friction rollers 33. This second tensioning belt 39 ensures that the two friction rollers 33 maintain contact with the wire harness 1. After the stop frame 361 releases the lock on the transmission wheel 341, the friction rollers 33 can rotate under the action of friction and the drive of the wire harness 1, thereby driving the second cutter 344 to cut a second incision in the second insulating layer.

[0058] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
