[0023] It should be noted that in the accompanying drawings of the present application, an arrow marked with X indicates the first direction X, an arrow marked with Y indicates the second direction Y, and an arrow marked with Z indicates the third direction Z. Among them, the first direction X represents the arrangement direction of the first welding assembly and the second welding assembly; the second direction Y represents the arrangement direction of the first welding assembly and the welding head; the third direction Z represents the arrangement direction of a plurality of welding grooves. And the first direction X, the second direction Y, and the third direction Z intersect with each other. Further, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The introduction of the first direction X, the second direction Y, and the third direction Z is to facilitate the description of the specific structural position relationship of the wire welding structure, and thus facilitate the understanding of its structure.

[0024] In the related art, during the ultrasonic welding of wires, the part of the wire welding structure in contact with the wire is easily worn, resulting in a reduced service life of the wire welding structure.

[0025] In view of this, an embodiment of the present application provides a wire welding structure, aiming to solve the above problems.

[0026] Please refer to Figures 1 - 3 , an embodiment of the present application provides a wire welding structure, which is mainly applied to the ultrasonic welding of wires. The wire welding structure has intersecting first direction X and second direction Y, and includes a welding head 1, a first welding assembly 2, a second welding assembly 3, and a third welding assembly 4. The first welding assembly 2 is arranged on one side of the welding head 1 along the second direction Y and is movably connected to the welding head 1. The first welding assembly 2 can move along the first direction X; the second welding assembly 3 is arranged on one side of the welding head 1 along the first direction X; the second welding assembly 3 includes a second bracket 31 and a second welding part 32. The second welding part 32 is detachably connected to the second bracket 31; a part of the second welding part 32 protrudes on the side of the welding head 1 facing the first welding assembly 2. The second welding part 32 is arranged at an interval from the first welding assembly 2 along the first direction X; the second bracket 31 can drive the second welding part 32 to move along the second direction Y; the third welding assembly 4 is movably connected to the side of the second welding part 32 along the second direction Y away from the welding head 1. The third welding assembly 4 is arranged at an interval from the first welding assembly 2 along the first direction X; the third welding assembly 4 can move along the first direction X and can move along the second direction Y with the second welding part 32.

[0027] In the embodiment of the present application, the wire welding structure clamps the wire along the first direction X by arranging the first welding component 2 and the second welding component 3, and clamps the wire along the second direction Y by arranging the third welding component 4 in cooperation with the welding head 1, so as to realize the positioning welding of the wire; wherein, the second welding component 3 is detachably connected to the second welding part 32 by arranging the second bracket 31. At this time, when the second welding part 32 is worn and fails during the welding process, the second welding part 32 can be disassembled and replaced in time. Compared with directly replacing the second welding component 3, the overall service life of the second welding component 3 can be correspondingly improved. At the same time, only the worn second welding part 32 needs to be replaced, effectively reducing the equipment use cost.

[0028] Specifically, the first welding component 2 is connected to the welding head 1 and is located on one side of the welding head 1 along the second direction Y. The second welding part 32 has no displacement in the first direction X, and a part of the second welding part 32 is spaced from the first welding component 2 along the first direction X. At this time, a positioning space 5 for accommodating the wire is formed between the first welding component 2, the welding head 1 and the second welding part 32. When welding the wire, the wire is sorted out and placed in the positioning space 5 to perform subsequent welding. Among them, the first welding component 2 can move along the first direction X, so that the distance between the first welding component 2 and the second welding part 32 can be adjusted. At this time, the width of the wire harness can be limited. Further, the third welding component 4 can move along the first direction X and finally contact the first welding component 2 to form a closed positioning space 5 around the end of the wire. Then, the whole second welding component 3 and the third welding component 4 both move along the second direction Y so that the third welding component 4 moves close to the welding head 1 along the second direction Y to realize the pressing of the wire harness, and further facilitate the ultrasonic welding of the wire. At this time, the thickness of the wire harness can be limited.

[0029] It should be noted that the first welding component 2 in the embodiment of the present application can be a wire gathering block, the second welding component 3 can be a bottom die arm, and the third welding component 4 can be a bottom die, which are used to realize the ultrasonic welding of the wire.

[0030] It should also be noted that by designing the second welding assembly 3 as a split structure of the second bracket 31 and the second welding part 32, the replaceability of the welding part can be achieved. After being worn out after multiple wire weldings, compared with replacing the entire second welding assembly 3, only replacing the second welding part 32 can timely replace the new second welding part 32, and the second bracket 31 that is not in contact with the wire does not need to be replaced, which can extend the service life of the second bracket 31, and thus effectively extend the service life of the second welding assembly 3. In addition, due to the special operating environment requirements of ultrasonic welding, the material cost of each component for wire welding is relatively high. By only replacing the vulnerable second welding part 32, the usage cost of the second welding assembly 3 can be effectively reduced, thereby reducing the usage cost of the equipment and further reducing the production cost, which is beneficial to cost reduction and efficiency improvement.

[0031] It should also be noted that in the embodiment of the present application, the detachable connection between the second bracket 31 and the second welding part 32 can specifically be that the second bracket 31 and the second welding part 32 are locked and connected through a connecting member 33. The connecting member 33 can be a bolt. At this time, threaded holes are respectively provided on the second bracket 31 and the second welding part 32, and the second welding part 32 can be locked on the second bracket 31, as Figure 3 shown. Or, a protruding positioning pin can be provided on the side of the second bracket 31 facing the second welding part 32, and a positioning hole can be provided on the second welding part 32. The positioning pin is detachably inserted into the positioning hole to achieve the detachable connection between the second welding part 32 and the bracket. Among them, both the positioning pin and the positioning hole are polygonal structures, so that mutual limitation between the positioning pin and the positioning hole can be achieved to prevent the second welding part 32 from twisting. This solution is not shown in the drawings. In addition, a limiting groove can be provided on the second bracket 31, and the second limiting part can be directly embedded in the limiting groove. Limiting protrusions can also be provided on the groove wall of the limiting groove, and limiting sliding grooves can be provided at corresponding positions on the outer side of the second limiting part. The limiting protrusions cooperate with the limiting groove to achieve the limitation of the second limiting part and the second bracket 31 along the second direction Y. This solution is also not shown in the drawings. Of course, the second bracket 31 and the second limiting part can also be other publicly known detachable connection methods, which will not be elaborated here.

[0032] Please refer to Figure 2 、 Figure 3 and Figure 6 , in some embodiments, the second welding part 32 includes a second welding surface 321 and a fifth welding surface 325 arranged oppositely; the second welding surface 321 is movably connected to the welding head 1, and the fifth welding surface 325 is connected to the second bracket 31; or, the fifth welding surface 325 is movably connected to the welding head 1, and the second welding surface 321 is connected to the second bracket 31.

[0033] In the embodiment of the present application, the second welding part 32 is provided with a second welding surface 321 and a fifth welding surface 325. The second welding surface 321 and the fifth welding surface 325 may have the same or different structures. At this time, the second welding part 32 can have two welding surfaces, so that when the second welding surface 321 is worn out after multiple uses and cannot continue welding, the fifth welding surface 325 can be replaced to face the welding head 1 and be movably connected to the welding head 1. At this time, the fifth welding surface 325 can continue to be used to continue welding, thereby further increasing the service life of the second welding part 32, and further increasing the service life of the second welding assembly 3. Furthermore, it is equivalent to increasing the service life of the entire wire welding structure. In this way, the use cost of the equipment can be effectively reduced, and the production cost can be reduced.

[0034] As Figure 3 shown, in some embodiments, the second bracket 31 has a groove 311. The groove 311 is provided on the side of the second bracket 31 facing the welding head 1. At least a part of the second welding part 32 is detachably arranged in the groove 311, and the second welding surface 321 or the fifth welding surface 325 is located outside the groove 311.

[0035] In the embodiment of the present application, by providing the groove 311 on the second bracket 31 and arranging the second welding part 32 in the groove 311, the side wall of the groove 311 can limit the second welding part 32 in the third direction Z at this time. The second welding part 32 can be directly embedded in the groove 311. At this time, there is a large frictional force between the inner wall of the groove 311 and the outer surface of the second welding part 32, which can realize the fixation of the second limiting part.

[0036] Furthermore, in some embodiments, the second bracket 31 has a first through hole 312. The first through hole 312 penetrates the second bracket 31 along the first direction X; the second welding part 32 has a second through hole 322. The second through hole 322 penetrates the second welding part 32 along the first direction X; the second welding assembly 3 further includes a connecting piece 33. The connecting piece 33 is detachably inserted through the first through hole 312 and the second through hole 322 to detachably connect the second bracket 31 and the second welding part 32.

[0037] By providing through holes and using the connecting piece 33 to be detachably inserted therein, the effective connection between the second bracket 31 and the second welding part 32 can also be realized.

[0038] It should be noted that at this time, the first through hole 312 and the second through hole 322 can be threaded holes, and the connecting member 33 can be a screw or a bolt. By screwing the connecting member 33 into the first through hole 312 and the second through hole 322, the detachable connection between the second welding part 32 and the second is realized. Additionally, at this time, the first through hole 312 and the second through hole 322 can also be special-shaped holes or polygonal holes, and the cross-section of the connecting member 33 can be special-shaped or polygonal that matches the first through hole 312 and the second through hole 322. In this way, the connecting member 33 can be directly passed through the first through hole 312 and the second through hole 322, realizing the detachable connection between the second welding part 32 and the second, and preventing the second welding part 32 and the second from twisting relative to each other.

[0039] Of course, at this time, a groove 311 can also be provided on the second bracket 31. The first through hole 312 communicates with the groove 311, that is, the first through hole 312 penetrates the bottom of the groove 311. The second welding part 32 is arranged in the groove 311, and the second through hole 322 corresponds to the first through hole 312 one by one. At this time, the connecting member 33 is detachably passed through the first through hole 312 and the second through hole 322, which can further realize the detachable connection between the second welding part 32 and the second bracket 31, and the connection effect is more stable.

[0040] It should also be noted that there can be multiple first through holes 312, multiple second through holes 322, and multiple connecting members 33. The numbers of the first through holes 312, the second through holes 322, and the connecting members 33 correspond to each other one by one to achieve multi-point fixation, further improving the stability of the connection and fixation.

[0041] Please refer to Figure 1 、 Figure 7 and Figure 9 In some embodiments, the first welding assembly 2 includes a first bracket 21 and two first welding parts 22. The two first welding parts 22 are oppositely arranged at both ends of the first bracket 21 along the first direction X, and both of the two first welding parts 22 are connected to the first bracket 21; one of the two first welding parts 22 is arranged on one side of the welding head 1 along the second direction Y and is movably connected to the welding head 1.

[0042] In the embodiments of the present application, the first welding part 22 is used for movably connecting with the welding head 1 and cooperating with the second welding part 32 and the third welding assembly 4 to realize wire ultrasonic welding. Therefore, the first welding part 22 will also be worn during frequent welding, resulting in a reduced service life. In the present application, by symmetrically arranging two first welding parts 22 at both ends of the first bracket 21, the service life of the first welding assembly 2 can be doubled, thereby further improving the overall service life of the wire welding structure, reducing the equipment use cost, and further reducing the production cost.

[0043] Please refer toFigures 7 - 9 , in some embodiments, the first welding portion 22 includes a first welding surface 221, and a first positioning surface 222 and a third positioning surface 223 that are oppositely arranged along the second direction Y. The first welding surface 221 is disposed on a side of the first welding portion 22 away from the first bracket 21. The first welding surface 221 is spaced apart from the second welding surface 321 along the first direction X; the first positioning surface 222 or the third positioning surface 223 is movably connected to the welding head 1.

[0044] In the embodiments of the present application, by providing the first positioning surface 222 and the third positioning surface 223, and the first positioning surface 222 or the third positioning surface 223 is movably connected to the welding head 1, it is possible to achieve a 180-degree flip of the first welding portion 22 with the first direction X as the axis, so as to reverse the use end of the first welding surface 221, thereby further increasing the service life of the first welding portion 22.

[0045] Specifically, since when welding a wire, the first welding portion 22 needs to cooperate with the second welding portion 32 and the third welding assembly 4 to achieve the positioning and welding of the wire. Among them, during welding, the first welding surface 221 of the first welding portion 22 faces the second welding portion 32. As the third welding assembly 4 moves along the second direction Y toward the welding head 1 to press the wire, at this time, only one end of the first welding surface 221 close to the welding head 1 contacts the wire, and the end away from the welding head 1 does not contact the wire. Therefore, during welding, the end of the first welding surface 221 away from the wire and the welding head 1 is rarely worn or not worn, while the end of the first welding surface 221 close to the wire and the welding head 1 is worn more seriously. After multiple weldings, a problem of inability to continue welding will occur. At this time, by flipping the first welding portion 22 by 180 degrees, the end of the first welding surface 221 that was originally away from the wire and the welding head 1 is adjusted to be close to the wire and the welding head 1, and at this time, welding can continue to be used, so as to double the service life of the first welding portion 22. Both of the two first welding portions 22 can be doubled, so that the service life of the first welding assembly 2 is increased by three times compared to the initial state, effectively extending the service life of the first welding assembly 2.

[0046] It should be noted that since the first welding portion 22 still needs to be movably connected to the welding head 1 after being flipped by 180 degrees, the present application provides that the first welding portion 22 includes a first positioning surface 222 and a third positioning surface 223 that are oppositely arranged along the second direction Y, which can support the flipping of the first welding portion 22 and be movably connected to the welding head 1. Among them, the first positioning surface 222 and the third positioning surface 223 are used to cooperate with the welding head 1 to achieve the guiding of the first welding portion 22 along the first direction X and the positioning along the third direction Z.

[0047] Such as Figure 10As shown, in some embodiments, the wire welding structure has a third direction Z intersecting with the first direction X and the second direction Y; the welding head 1 includes a fourth welding surface 11 and a plurality of first protrusions 12. The fourth welding surface 11 is disposed on the side of the welding head 1 facing the first welding portion 22. The fourth welding surface 11 is movably connected to the first positioning surface 222 or the third positioning surface 223 of a first welding portion 22. The plurality of first protrusions 12 are arranged at intervals along the third direction Z, and the plurality of first protrusions 12 are all connected to the fourth welding surface 11. The first welding portion 22 has a plurality of first positioning grooves 224. A part of the first positioning grooves 224 penetrate the first positioning surface 222 along the second direction Y and are arranged at intervals along the third direction Z. Another part of the first positioning grooves 224 penetrate the third positioning surface 223 along the second direction Y and are arranged at intervals along the third direction Z. Each first protrusion 12 is disposed in a first positioning groove 224, and the first protrusion 12 can move along the first direction X within the first positioning groove 224.

[0048] In the embodiments of the present application, the first protrusion 12 and the first positioning groove 224 are arranged in cooperation with each other, which can realize the guiding of the first welding portion 22 along the first direction X and the positioning along the third direction Z, and prevent the position of the first welding portion 22 from shifting when moving along the first direction X.

[0049] As Figure 8 As shown, in some embodiments, the first welding portion 22 has a plurality of first welding grooves 225. The plurality of first welding grooves 225 all penetrate the first welding surface 221 and are arranged at intervals along the third direction Z. The second welding portion 32 includes a plurality of second welding grooves 326. A part of the second welding grooves 326 penetrate the second welding surface 321 and are arranged at intervals along the third direction Z. Another part of the second welding grooves 326 penetrate the fifth welding surface 325 and are arranged at intervals along the third direction Z.

[0050] In the embodiments of the present application, by arranging the first welding groove 225 and the second welding groove 326 to cooperate with each other, when the first welding surface 221 and the second welding surface 321 cooperate to clamp and weld the wire, the first welding groove 225 and the second welding groove 326 provide a partial deformation space for the wire, so that it is more conducive to the shrinkage clamping of the wire harness by the parts where the first welding surface 221 and the second welding surface 321 are attached to the wire. The locally bent and uneven wires are squeezed into the first welding groove 225 and the second welding groove 326, so that it is more convenient to tighten multiple wires and achieve good welding of multiple wires.

[0051] As Figure 7 As shown, in some embodiments, the first bracket 21 has a plurality of adjustment holes 211. The plurality of adjustment holes 211 are arranged along the direction in which the two first welding portions 22 are arranged. The plurality of adjustment holes 211 penetrate the first bracket 21 along the first direction X. The adjustment holes 211 are used to adjust the distance between the first welding portion 22 and the second welding portion 32 along the first direction X.

[0052] In the embodiment of the present application, the adjustment hole 211 is used to adjust the specific position of the first welding assembly 2 in the first direction X when the first welding assembly 2 is installed on the frame of the wire welding device. It can be a fine adjustment. After the first welding assembly 2 moves in place in the first direction X towards the second welding part 32, the error between the distance between the first welding surface 221 and the second welding surface 321 and the expected distance is made smaller. At the same time, the distance between the first welding surface 221 and the second welding surface 321 can be further adjusted according to the actual width of the welded wire terminal to achieve effective welding.

[0053] Specifically, in the embodiment of the present application, the adjustment hole 211 can be an oblong hole (waist-shaped hole), a rectangular hole, etc., as long as it can achieve the adjustment of the position of the first welding assembly 2 in the first direction X.

[0054] As Figure 7 shown, in some embodiments, the first bracket 21 has a limiting platform 212, and the limiting platform 212 is arranged in the adjustment hole 211 and connected to the hole wall of the adjustment hole 211.

[0055] In the embodiment of the present application, by providing the limiting platform 212, at this time, the adjustment hole 211 is equivalent to a counterbore with stepped grooves on both sides. At this time, the fixing member (which can be a bolt) for fixing the first welding assembly 2 can sink into the adjustment hole 211, so as to avoid interference of the fixing member.

[0056] It should be noted that the limiting platform 212 can be annular, surrounding the inner wall of the adjustment hole 211 to achieve better limiting of the bolt. The limiting platform 212 can be located in the middle of the adjustment hole 211, so that the adjustment hole 211 is symmetrical with respect to the limiting platform 212. At this time, it is convenient for the flipping of the first welding part 22.

[0057] Please refer to Figure 1 、 Figure 2 、 Figures 4 - 6 and Figure 11, in some embodiments, the wire welding structure has a third direction Z intersecting the first direction X and the second direction Y; the second welding portion 32 includes a second positioning surface 323, and the second positioning surface 323 is disposed on a side of the second welding portion 32 away from the welding head 1 along the second direction Y. The second welding portion 32 has a plurality of second positioning grooves 324, and the plurality of second positioning grooves 324 penetrate through the second positioning surface 323. The plurality of second positioning grooves 324 are spaced along the third direction Z; the third welding assembly 4 includes a third welding surface 41 and a plurality of second protrusions 42.
