Detailed Description of the Invention

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

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

[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 two 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 at the middle part corresponding to the 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 stage; 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] Circular grooves are respectively provided at both ends of the corresponding locking pin 23 in the first housing 21; the projection of the cutting path 211 on the horizontal cross section of the first housing 21 partially overlaps with the projection of the circular groove on the horizontal cross section of the first housing 21, so that when the first housing 21 is cut off, the restriction of the first housing 21 on the locking pin 23 can be released, so that the locking pin 23 after cutting can slide in the circular groove;

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

[0043] When the wire harness 1 is needed, 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 wire 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 cutting on the wire harness 1 during the rotation process, thereby leaving a first incision on the first insulating layer of the wire harness 1, exposing a plurality of wire cores; then, the wire harness 1 is pulled out in a direction away from the cutting path 211, and the first insulating layer portion from the first incision to the incision position of the wire harness 1 is stripped off and detached from the first shell 21;

[0044] like Figure 7As shown, when the exposed wire cores move between the two flattening rollers 32, the two flattening rollers 32 squeeze the wire cores, causing a number of wire cores to be arranged horizontally in a specific direction for subsequent welding operations; subsequently, as Figure 7 shown, when the first cutting position of the wire harness 1 comes opposite to the stripping assembly, the locking assembly releases the locking of the second cutting knife group. Then, while the wire harness 1 is being pulled outwards, the wire harness 1 drives the two friction rollers 33 to rotate through friction. 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 cuts on the second insulating layers of the horizontally arranged wire cores, facilitating the subsequent removal of the second insulating layer and greatly improving the efficiency of wire stripping; when the wire cores enter the stripping assembly, the stripping assembly strips the second insulating layers cut on each wire core from the wire cores until the wire harness 1 is pulled out from the second wire stripping mechanism 3, realizing the stripping of the first and second insulating layers of the wire harness 1 and the directional arrangement of the wire cores.

[0045] In this embodiment, by pre - sleeving a wire stripping structure on the wire harness 1, the insulating layer can be removed efficiently and conveniently, improving the wire stripping efficiency, reducing manual intervention, lowering the labor intensity, and also enhancing the consistency and stability of the product; and by cutting multiple cuts on the wire cores, when stripping the insulating layer, the multiple notches make the force more evenly distributed at different positions of the wire cores, greatly reducing the risk of excessive local force on the wire cores, the risk of deformation and fracture, effectively protecting the integrity and electrical performance of the wire cores, and improving the reliability of use of the wire harness 1.

[0046] Meanwhile, the multiple cuts can better break the adhesion between the insulating layer and the wire cores, making the insulating layer more smooth during stripping, more easily peeled off from the wire cores completely, reducing the problem of insulating layer residue, and providing a better wire core preparation state for subsequent welding.

[0047] As Figure 4 shown, for the multi - core wire harness of the ultrasonic probe in this embodiment, in some embodiments, the first cutting knife group includes a first cutting tool 251 radially movably arranged on the rotating seat 22 along the radial direction of the rotating seat 22; preferably, the first cutting tool 251 is arc - shaped to better fit the outer peripheral surface of the wire harness 1; the first cutting tool 251 is provided with a tool shaft 252 movably penetrating the rotating seat 22; a spring 253 is sleeved on the outer wall of the tool shaft 252; both ends of the spring 253 are in contact with the tool shaft 252 and the rotating seat 22 respectively; preferably, a first clamping platform is provided at the end of the tool shaft 252, and the spring 253 abuts against the first clamping platform; a driving groove 212 is provided on the inner wall of the first housing 21 at the position corresponding to the tool shaft 252; the tool shaft 252 is movably embedded in the driving groove 212; when the rotating seat 22 drives the first cutting tool 251 to rotate, the driving groove 212 causes the first cutting tool 251 to extend towards the axis direction of the rotating seat 22 against the elastic force of the spring 253. Preferably, each rotating seat 22 is provided with a plurality of first cutting knife groups evenly distributed in the circumferential direction.

[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 housing 21. The rotating seat 22 synchronously drives each first cutting tool group to rotate. When the first cutting tool group rotates relative to the first housing 21, the driving groove 212 squeezes the first cutting tool 251 through the tool shaft 252, causing the first cutting tool 251 to extend inward against the elastic force of the spring 253. The first cutting tool 251 cuts into the first insulating layer until the tool shaft 252 moves out of the driving groove 212. At this time, the first cutting tool 251 remains in the extended state, thereby cutting a first incision in the first insulating layer. When the wire harness 1 is pulled out, the cut first insulating layer is detached from the wire harness 1, thus completing the peeling operation of the first insulating layer.

[0049] Exemplarily, as Figure 5 shown, the driving groove 212 includes a clamping groove and an inclined groove; initially, the first clamping platform is accommodated in the clamping groove under the elastic force of the spring 253. When the rotating seat 22 drives the first cutting tool 251 to rotate, the first clamping platform moves out of the clamping groove into the inclined groove, so that the first housing 21 generates a squeezing force on the first cutting tool 251, causing the first cutting tool 251 to extend radially inward to cut into the first insulating layer.

[0050] As Figure 8 and Figure 9 shown, for the multi-core wire harness for an ultrasonic probe in this embodiment, in some embodiments, the second cutting tool group includes two oppositely arranged driving wheels 341, two oppositely arranged eccentric wheels 342, a tool holder 343 connected between the two eccentric wheels 342, and a plurality of second cutting tools 344 arranged at equal intervals on the tool holder 343; the driving wheels 341 are rotatably arranged on the inner side wall of the second housing 31; the driving wheels 341 are in driving connection with one end of the corresponding friction rollers 33; the driving wheels 341 are provided with eccentric shafts; the eccentric wheels 342 are rotatably arranged on the eccentric shafts; the outer peripheral wall of the driving wheels 341 is provided with locking notches 3411 for locking and cooperating with the locking assembly; an extension arm 3421 extends from the outer peripheral wall of the eccentric wheel 342, and a limit post 345 is movably arranged on the extension arm 3421; one end of the limit post 345 movably penetrates through the second housing 31.

[0051] Specifically, the friction roller 33 is drivingly connected to the driving wheel 341 through a transmission belt; after the locking assembly moves out of the locking notch 3411, the locking of the driving wheel 341 by the locking assembly is released. At this time, the two friction rollers 33 can rotate during the movement of the wire harness 1. The friction roller 33 drives the driving wheel 341 to rotate through the transmission belt, and the driving 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 post 345, the eccentric wheel 342 drives the second cutting tool 344 to rotate through the tool holder 343. In this way, a plurality of second cuts can be cut at equal intervals on the second insulating layer on the wire core. The plurality of second cuts can better break the adhesion between the second insulating layer and the wire core, making the second insulating layer more smooth when detaching, and more easily peeled off from the wire core completely, reducing the problem of the remaining second insulating layer, and facilitating the subsequent welding operation.

[0052] As Figure 8 and Figure 10 shown, in some embodiments, the ultrasonic probe multi-core wire harness of this embodiment, the locking assembly includes two spaced-apart limiting frames 361. Specifically, the two limiting frames 361 are distributed on both sides inside the second housing 31, and the two locking assemblies are symmetrically arranged up and down; both ends of the first tension spring 37 are respectively connected to the limiting frame 361 and the corresponding limiting frame 361 of the other locking assembly; one end of the limiting frame 361 is movably arranged on the inner side wall of the second housing 31 and is used for cooperating with the locking notch 3411, and the other end of the limiting frame 361 is in movable abutment with the peeling assembly. As Figure 7 , Figure 8 , Figures 10 to 15As shown, in the multi-core wire harness for an ultrasonic probe of this embodiment, in some embodiments, the stripping assembly includes a stripping frame 351 disposed in the second housing 31. In the stripping frame 351, two driving sliders 352, two sliding rods 353, two first clamping plates 354, and two second clamping plates 355 are movably arranged in an up-and-down opposite manner; each driving slider 352 is provided with a first inclined boss 3521 and a second inclined boss 3522 that are staggeredly arranged; on the opposite inner side walls of the stripping frame 351, L-shaped sliding grooves 3511 are respectively provided corresponding to each sliding rod 353; the vertical section of the L-shaped sliding groove 3511 is arranged away from the friction roller 33; both ends of the sliding rod 353 are connected to one end of the second housing 31 close to the friction roller 33 by a second tension spring 356; both ends of the sliding rod 353 are movably inserted into the L-shaped sliding grooves 3511; each first clamping plate 354 protrudes with a third inclined boss 3541 for cooperating with the first inclined boss 3521; each second clamping plate 355 protrudes 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 staggeredly arranged; both ends of the driving slider 352 protrude with first pushing portions 3523; both ends of the sliding rod 353 are provided with second pushing portions 3531 for cooperating with the first pushing portions 3523; the other end of the limiting frame 361 is in movable abutment with the corresponding sliding rod 353.

[0053] Initially, one end of the limiting frame 361 is inserted into the locking notch 3411 to lock the transmission wheel 341. The sliding rod 353 is located in the vertical section of the L-shaped sliding groove 3511. At this time, the second tension spring 356 is in a stretched state, and the two sliding rods 353 respectively abut against the outer peripheral wall of the wire harness 1, as Figure 13 shown, the first inclined boss 3521 is in abutting cooperation with the corresponding third inclined boss 3541; when the first incision of the wire harness 1 comes below the sliding rod 353, under the action of the first tension spring 37, the two vertically opposite limiting frames 361 move towards each other, and at the same time, the two sliding rods 353 also move towards each other, so that one end of the limiting frame 361 moves out of the locking notch 3411, thereby releasing the locking of the transmission wheel 341, as Figure 8 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, and a plurality of second incisions are cut at equal intervals on the second insulating layer on the wire core; at the same time, the end of the sliding rod 353 enters the horizontal section of the L-shaped sliding groove 3511, and under the action of the second tension spring 356, the sliding rod 353 slides along the horizontal section of the L-shaped sliding groove 3511 towards the direction of the friction roller 33. When the second push rod of the sliding rod 353 abuts against the first pushing portion 3523 of the driving slider 352, as Figure 14As shown, the sliding rod 353 pushes the driving sliders 352 to slide synchronously. The two driving sliders 352 are respectively engaged with the third inclined bosses 3541 of their respective corresponding first clamping plates 354 through the first inclined bosses 3521, so that the two first clamping plates 354 move towards each other, thereby clamping a plurality of horizontally arranged wire cores. With the continuous pulling of the wire harness 1, the two first clamping plates 354 cause a part of the second insulating layer to be separated from the wire cores until the first inclined bosses 3521 are separated from the third inclined bosses 3541; with the further sliding of the driving sliders 352, when the second inclined bosses 3522 of the two driving sliders 352 are respectively in contact and cooperation with the fourth inclined bosses 3551 on their respective corresponding second clamping plates 355, as Figure 15 shown, the two driving sliders 352 cause the two second clamping plates 355 to move towards each other, thereby clamping a plurality of wire cores to strip the second insulating layer from the wire cores; in this way, through the secondary stripping method, it is beneficial to reduce the risks of excessive local stress, deformation and fracture of the wire cores, effectively protect the integrity and electrical performance of the wire cores, improve the quality and reliability of the wire harness 1, and make it easier to pull off the second insulating layer from the wire cores completely, reducing the problem of residual second insulating layer.

[0054] As Figure 11 and Figure 12 shown, for the multi-core wire harness for ultrasonic probes in this embodiment, in some embodiments, two pairs of mounting posts extend from the top wall and the bottom wall of the stripping frame 351 respectively; each mounting post is provided with a guiding chute; elastic floating pins are provided at both ends of the first clamping plate 354 and both ends of the second clamping plate 355; the pins are movably embedded in the guiding chute. Specifically, the guiding chute includes a first locking groove, an inclined plane groove, a vertical groove and a second locking groove connected in sequence. The first locking groove is arranged at one end far from the axis of the wire harness 1. Initially, the pins are located in the first locking groove; in this embodiment, the 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 to move, the pins enter the inclined plane groove from the first locking groove, and then enter the vertical groove through the inclined plane groove until they enter the second locking groove from the vertical groove. At this time, the first clamping plate 354 or the second clamping plate 355 clamps a plurality of wire cores to strip the second insulating layer.

[0055] As Figure 9 shown, for the multi-core wire harness for ultrasonic probes in this embodiment, in some embodiments, the extension arm 3421 is provided with a strip-shaped hole; the other end of the limit post 345 is movably clamped with the strip-shaped hole; preferably, a second clamping platform is provided at the other end of the limit post 345, and the second clamping platform is movably clamped on the extension arm 3421. In this embodiment, the strip-shaped hole is provided to enable the limit post 345 to make an adaptive movement relative to the eccentric wheel 342 when the eccentric wheel 342 rotates.

[0056] As Figure 8As shown, for the multi-core wire harness for an ultrasonic probe in this embodiment, in some embodiments, a first tension belt 38 is connected between two flattening rollers 32; accommodating grooves are evenly distributed on the outer peripheral wall of each flattening roller 32 along its axial direction. In this embodiment, by providing the first tension belt 38, the two flattening rollers 32 are tensioned by the first tension belt 38 to ensure the shaping and arranging effect of the wire cores on the two flattening rollers 32; after several wire cores enter between the two flattening rollers 32, the flattening rollers 32 shape and arrange the several wire cores so that the several wire cores are respectively embedded into the accommodating grooves one by one, so that the several wire cores can be horizontally arranged.

[0057] As Figure 8 shown, for the multi-core wire harness for an ultrasonic probe in this embodiment, in some embodiments, a second tension belt 39 is connected between two friction rollers 33.
