Description

Technical Field

[0001] This invention relates to the field of bearing ball filling technology, specifically to a welding device and method for welding multi-core wire harnesses with male connectors for aviation applications. Background Technology

[0002] Soldering multi-core wire harnesses for aviation use requires stripping the outer sheath of the wire cores and removing the oxide layer. The wire cores of the multi-core wire harness are then clamped and positioned on the welding head, and the wire cores are pressed down on the welding head. Ultrasonic vibration is used to weld the wire cores of the multi-core wire harness using the welding head. However, traditional multi-core wire harness welding devices still have technical problems that urgently need to be solved.

[0003] In traditional methods, wire stripping and oxide removal need to be done in separate steps, which is highly dependent on manual labor or independent equipment, resulting in low efficiency and poor weld conductivity due to oxide residue. In addition, residual metal debris on the welding head requires machine shutdown for cleaning, affecting continuous operation. Existing technologies lack an integrated device that combines wire stripping, oxide removal, and welding head cleaning, leading to cumbersome processes and unstable welding quality. Summary of the Invention

[0026] The rubber sleeve is fixed to the upper end of the hollow sleeve, forming a cylindrical structure with the hollow sleeve;

[0028] Furthermore, the application component includes:

[0029] The sponge is fixed inside the rubber sleeve and located on one side of the fine sandpaper;

[0030] Multiple pieces of wicking material are evenly distributed inside the hollow sleeve, with both ends penetrating through the two ends of the hollow sleeve and extending into the interior of the sponge.

[0049] Secondly, a method of using an aviation male multi-core wire harness welding device, the method of using the aviation male multi-core wire harness welding device includes:

[0050] Pass one end of the multi-core wire bundle to be stripped through the movable tube and the sleeve in sequence, so that one end of the wire bundle extends out of the sleeve by a certain length.

[0051] Control the electric lifting rod to retract, and drive the connecting block and wire stripper to move downward together through the telescopic plate, so that the rubber clamp and rubber seat cooperate to clamp the multi-core wire harness. At the same time, the wire stripper and the semi-circular knife cooperate to cut the outer sheath of the multi-core wire harness, and the pressure rod squeezes the rubber sleeve downward through the pressure plate, so that the fine sandpaper adheres to the outside of the wire harness and the sponge adheres to the outside of the wire harness.

[0052] Place the stripped or unstripped cores of the multi-core wire harness onto the soldering head;

[0053] The electric telescopic rod is extended so that the right clamping block engages with the T-seat to clamp the wire harness core placed on the welding head. At the same time, the movable cylinder moves to the left, which in turn moves the fixed end of the telescopic plate to the left via the electric lifting rod. This stretches the telescopic plate and causes the rubber clamp to engage with the rubber seat to pull the multi-core wire harness that needs to be stripped to the left. This separates the multi-core wire harness from the outer sheath cut by the wire stripper and the semi-circular blade. Meanwhile, the wire harness core passes through fine sandpaper and sponge in sequence during the movement. The external force of the movement rubs against the fine sandpaper to lightly polish the wire core, and the sponge squeezes out cleaning agent to wipe the surface of the wire core to remove the oxide layer.

[0054] Control the extension of the electric lever to move the upper clamping block to the right above the clamped wire core;

[0055] The electric actuator retracts, which drives the upper clamping block to move downwards through the T-seat, causing the upper clamping block to press down on the wire harness core, making the core tightly adhere to the welding head.

[0056] The transducer is activated to generate ultrasonic waves, which are then transmitted to the welding head via an amplitude transformer and welding socket. The ultrasonic vibration is used to weld the cores of a multi-core aviation male connector wire harness.

[0057] The above-described solution of the present invention has at least the following beneficial effects:

[0058] Through the synergistic action of the stripping mechanism and the deoxidation mechanism, the wire core stripping and oxide layer removal are completed simultaneously during the welding process, reducing manual intervention, ensuring the cleanliness of the wire core surface, improving the welding conductivity, the continuous operation capability of the device, and the welding effect and quality of the wire harness, and ensuring the welding conductivity.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0074] like Figures 1 to 12 As shown, an embodiment of the present invention provides a welding device for multi-core wire harnesses with male connectors for aviation applications, including a controller 1 and a housing 2. A transducer 3 is electrically connected to the controller 1 inside the housing 2. An amplitude transformer 4 is connected to the output end of the transducer 3. A welding seat 5 is connected to the end of the amplitude transformer 4 away from the transducer 3. A welding head 6 is fixed to the end of the welding seat 5, and the welding end of the welding head 6 extends vertically upward to the outside of the housing 2. A support 7 is fixed inside the housing 2, and the support 7 is located on one side of the welding head 6. An upper clamping block 11 is provided on the support 7 for lifting, lowering, and translating. An electric telescopic rod 12 is fixed inside the housing 2 by a fixing component. The telescopic end of the electric telescopic rod 12 is connected to a right clamping block 14 by a support component to fix the multi-core wire harness to the welding head 6. The device also includes:

[0075] The wire stripping mechanism is connected to one side of the support 7 and the front of the right clamping block 14. It includes a semi-circular blade 21 connected to the support 7 via a connecting component, a wire stripping blade 25 that is raised and lowered above the semi-circular blade 21, a movable cylinder 19 fixed to the right clamping block 14 via a connecting component, a rubber seat 20 fixed inside the movable cylinder 19, and a rubber clamp 27 that is raised and lowered above the rubber seat 20, so as to move with the right clamping block 14 to realize the wire stripping work.

[0076] The deoxidation mechanism is set inside the stripping mechanism, including a support and grinding assembly that passes through the movable cylinder 19 and is located on the side of the semi-ring knife 21 near the glue seat 20. It also includes a pressing part set on the support and grinding assembly and a coating assembly connected to the support and grinding assembly to remove the oxide layer on the surface of the wire core.

[0077] The scraping mechanism is located on one side of the welding head 6 and the deoxidation mechanism. It includes a shovel-push assembly that is translatably mounted on the support 7 and located on one side of the welding head 6, and a transfer assembly connected to the shovel-push assembly. The transfer assembly is fixedly connected to the connecting part that is connected to the half-ring cutter 21 to clean metal debris on the welding head 6 when the right clamping block 14 is reset after welding is completed.

[0078] Specifically, an electric push rod 8 is fixed to the inner side of the support 7 by a fixing component. The electric push rod 8 is in an extended state, and a T-shaped seat 9 is fixed to its telescopic end. The T-shaped seat 9 is slidably connected to the support 7. The upper clamping block 11 is fixed to the upper end of the T-shaped seat 9 by a fixing component. An electric rod 10 is fixed to the T-shaped seat 9 by a fixing component. The telescopic end of the electric rod 10 is fixedly connected to the upper clamping block 11. An electric telescopic rod 12 is fixed to one side of the inner wall of the outer shell 2 by a fixing component. A movable seat 13 is fixed to the telescopic end of the electric telescopic rod 12. The movable seat 13 is fixedly connected to the right clamping block 14 by a fixing component. The upper end of the right clamping block 14 is flush with the upper end of the T-shaped seat 9, and the lower end is flush with the upper end of the welding head 6.

[0079] The controller 1 can control the operation of the transducer 3, electric push rod 8, electric telescopic rod 12, electric lifting rod 22, electric rod 10 and lifting rod under the operation of the operator. The housing 2 can provide support for the transducer 3 and the amplitude rod 4. The amplitude rod 4 can provide support for the welding head 6 through the welding seat 5. The housing 2 can provide vibration space for the welding head 6 and can provide movement space for the movable seat 13, T seat 9, right clamp 14 and upper clamp 11. The support seat 7 can provide support and telescopic space for the electric push rod 8. The electric push rod 8 can push the T seat 9 up and down using the telescopic end. The support seat 7 can provide movement guidance for the T seat 9. The T seat 9 can provide a blocking effect for the wire harness during wire harness welding.

[0080] In practical application, the operator can place the stripped multi-core wire cores onto the welding head 6 as needed. Then, the operator controls the extension of the electric telescopic rod 12, which, supported by the housing 2, pushes the movable seat 13 towards the support 7 via its telescopic end. Simultaneously, the movable seat 13 drives the right clamping block 14 towards the T-seat 9, allowing the right clamping block 14 to engage with the T-seat 9 to clamp the wire cores placed on the welding head 6. Afterward, the operator controls the electric rod 12... The extension bar extends, pushing the upper clamping block 11 to the right and above the clamped wire harness core through the telescopic end. Then, the electric push rod 8 is controlled to retract, causing the electric push rod 8 to drive the upper clamping block 11 downward through the T-base 9, so that the upper clamping block 11 can press down on the wire harness core, making the wire harness core tightly attached to the welding head 6. Finally, the transducer 3 is controlled to start, so that the transducer 3 generates ultrasonic waves and transmits the vibration to the welding head 6 through the amplitude transformer 4 and the welding base 5, so that the welding head 6 uses ultrasonic vibration to weld the wire core of the aviation male multi-core wire harness.

[0081] In a preferred embodiment of the present invention, the peeling mechanism includes a cutting component and a clamping component. The cutting component is fixedly connected to the support 7, and the clamping component is connected to the right clamping block 14. The cutting component includes:

[0082] L-plate 15 is fixed to one side of support 7;

[0083] Sleeve 16 is fixed to the upper end of L plate 15 and is located on one side of movable cylinder 19, and is on the same axis as movable cylinder 19;

[0084] The semi-circular knife 21 is fixed to the inner bottom wall of the sleeve 16, and the wire stripper 25 is movably installed above the sleeve 16;

[0085] Support plate 24 is fixed above wire stripper 25.

[0086] Specifically, the support 7 provides stable support for the L-plate 15, the L-plate 15 provides support for the sleeve 16, the sleeve 16 provides stable support for the semi-ring knife 21, and provides a passage for the wire stripper 25 to pass through and move. The end faces of the semi-ring knife 21 and the wire stripper 25 that are close to each other are relatively sharp. The telescopic plate 23 provides stable support for the support plate 24 under the support of the electric lifting rod 22, so that the support plate 24 can provide support for the wire stripper 25.

[0087] The clamping and shifting assembly includes:

[0088] One end of the movable cylinder 19 is connected to a connecting rod 18, and the connecting rod 18 is fixedly connected to the right clamp through a connecting component;

[0089] The adhesive clip 27 is positioned above the movable cylinder 19;

[0090] Connecting block 26 is fixed on adhesive clip 27;

[0091] The pressure shifting component is mounted on the movable cylinder 19 and is telescopically connected to the support plate 24.

[0092] Specifically, the outer side of the right clamping block 14 is fixed with a fixed plate 17 by a fixing component, and the end of the fixed plate 17 is welded to the connecting rod 18, so that the right clamping block 14 can provide support for the movable cylinder 19 through the fixed plate 17 and the connecting rod 18, and can drive the movable cylinder 19 to move together when the right clamping block 14 moves. The movable cylinder 19 can provide stable support for the rubber seat 20, and can provide a through and moving channel for the rubber clamp 27. The rubber clamp 27 and the rubber seat 20 can cooperate to easily clamp the wire harness, and the telescopic plate 23 can provide support for the rubber clamp 27 through the connecting block 26.

[0093] Pressure shifting components include:

[0094] The electric lifting rod 22 is fixed on the movable cylinder 19 and is located on the side of the connecting block 26 away from the support plate 24;

[0095] The telescopic plate 23 is fixed at its fixed end to the telescopic end of the electric lifting rod 22 by a fixing component;

[0096] The telescopic end of the telescopic plate 23 is fixedly connected to the support plate 24, while the fixed end is fixedly connected to the connecting block 26.

[0097] Specifically, the movable cylinder 19 can provide stable support for the electric lifting rod 22, the electric lifting rod 22 can provide support for the telescopic plate 23, and can use the telescopic end to drive the telescopic plate 23 to rise and fall, so that the telescopic plate 23 can drive the connecting block 26, the support plate 24 and the pressure rod 33 to rise and fall together, and the electric lifting rod 22 is in the extended state.

[0098] In practical application, before extending the electric telescopic rod 12, the operator can pass one end of the multi-core wire harness that needs to be stripped through the movable cylinder 19 and the sleeve 16 in sequence, so that one end of the multi-core wire harness extends a certain length out of the sleeve 16 for welding. At the same time, the operator controls the electric lifting rod 22 to retract, causing it to move the telescopic plate 23 downward through the telescopic end. Simultaneously, the telescopic plate 23 will move the connecting block 26 and the wire stripper 25 downward together, so that the adhesive clamp 27 can cooperate with the adhesive base 20 to squeeze and clamp the multi-core wire harness. At the same time, the wire stripper 25, driven by the support plate 24, cooperates with the semi-circular blade 21 to cut the outer sheath of the multi-core wire harness. Afterward, the operator can place the wire core of the multi-core wire harness that does not need to be stripped onto the welding head 6 and control the electric... The telescopic rod 12 extends, which allows the right clamping block 14 to move the fixed plate 17 and the connecting rod 18 to the left. The connecting rod 18 then pushes the movable cylinder 19 to the left, which in turn causes the movable cylinder 19 to move the fixed end of the telescopic plate 23 to the left via the electric lifting rod 22. Under the action of external force and the positioning of the sleeve 16, the wire stripper 25, and the support plate 24, the telescopic plate 23 will move the rubber clamp 27 via the connecting block 26. The rubber clamp 27 and the rubber seat 20 will cooperate to pull the multi-core wire harness that needs to be stripped to the left, thereby separating the multi-core wire harness from the outer sheath cut by the wire stripper 25 and the semi-circular blade 21, thus facilitating the stripping of the multi-core wire harness.

[0099] In a preferred embodiment of the present invention, the grinding assembly includes:

[0100] Hollow sleeve 28 is fixed inside the sleeve 16 and located on one side of the semi-ring cutter 21;

[0101] The rubber sleeve 29 is fixed to the upper end of the hollow sleeve 28, forming a cylindrical structure with the hollow sleeve 28;

[0102] Two pieces of fine sandpaper 31 are fixed to the inside of the rubber sleeve 29 and the hollow sleeve 28, respectively.

[0103] Specifically, the sleeve 16 provides stable support for the hollow sleeve 28. During wire stripping, the worker needs to insert one end of the multi-core wire harness through the space between the hollow sleeve 28 and the rubber sleeve 29. The hollow sleeve 28 provides stable support for the rubber sleeve 29, and the rubber sleeve 29 provides support for the fine sandpaper 31. The rubber sleeve 29 is elastic and can deform under external force. When the external force is removed, it will rebound.

[0104] The application components include:

[0105] Sponge 30 is fixed inside the rubber sleeve 29 and located on one side of fine sandpaper 31;

[0106] Multiple wicks 32 are evenly arranged inside the hollow sleeve 28, with both ends penetrating through both ends of the hollow sleeve 28 and extending into the interior of the sponge 30.

[0107] The filling pipe 47 is installed through the outer wall of the hollow sleeve 28;

[0108] Rubber sheet 48 is fixed inside the injection tube 47.

[0109] Specifically, the rubber sleeve 29 provides stable support for the sponge 30, which can deform and rebound along with the rubber sleeve 29, and also provides support for the wick 32. The hollow sleeve 28 provides support for the wick 32, and the hollow sleeve provides storage space for the cleaning agent. The wick 32 can absorb the cleaning agent and transfer it to the sponge 30, allowing the sponge 30 to absorb and store the cleaning agent inside. The filling tube 47 provides storage space for the rubber sheet 48 under the support of the hollow sleeve 28. The operator can use an injection needle to pierce the rubber sheet 48 and insert it into the filling tube 47, and use the injection needle to inject the cleaning agent into the hollow sleeve 28. The hollow sleeve 28 is made of transparent material, which allows the operator to easily observe the liquid level of the cleaning agent.

[0110] The pressing parts include:

[0111] The upper end of the pressure rod 33 is fixed below the telescopic end of the telescopic plate 23, and the lower end is located between the movable cylinder 19 and the sleeve 16.

[0112] The pressure plate 34 is fixed to the lower end of the pressure rod 33 and is located on the rubber sleeve 29, extending to the inside of the movable cylinder 19 and the sleeve 16.

[0113] Specifically, the telescopic plate 23 can provide support for the pressure rod 33 and can drive the pressure rod 33 to move up and down together. The pressure rod 33 can use external force to drive the pressure plate 34 to move together, so that the pressure plate 34 can use external force to squeeze the rubber sleeve 29 downward.

[0114] In practical application, when the worker inserts one end of the multi-core wire harness through the sleeve 16, they first pass through the space between the hollow sleeve 28 and the sheath. When the electric lifting rod 22 retracts, the telescopic plate 23 pushes the pressure rod 33 downward, causing the pressure rod 33 to push the pressure plate 34 downward with external force. This allows the pressure plate 34 to squeeze the sheath downward, enabling the sheath to move the sponge 30 and fine sandpaper 31 downward together with external force. This allows the two pieces of fine sandpaper 31 to adhere to the outer side of the multi-core wire harness. At the same time, the sponge 30 will deform along with the wick cotton 32 under the downward pressure, allowing the sponge 30 to adhere to the outer side of the multi-core wire harness. The movable cylinder 19, in conjunction with the rubber seat 20 and the rubber clamp 27, holds and moves the wire harness. During the stripping process of the multi-core wire harness, the wire cores of the multi-core wire harness will pass through the gap between the wire stripping knife 25 and the semi-circular knife 21, the gap between the two fine sandpapers 31, and the gap between the sponge 30 and the hollow sleeve 28 as the moving cylinder 19 moves along with it. During the passage, the wire cores of the multi-core wire harness are rubbed by the external force of the movement, allowing the fine sandpapers 31 to lightly polish the wire cores of the multi-core wire harness. Meanwhile, the sponge 30 will squeeze out the cleaning agent stored in it during the deformation process. During the contact and friction between the wire cores of the multi-core wire harness and the sponge 30, the cleaning agent is wiped on the delicate surface of the multi-core wire harness. The sponge 30 wipes the wire cores, thereby removing the oxide layer on the surface of the wire cores and preventing the oxide layer from affecting the soldering conductivity.

[0116] The telescopic rod 35 has its fixed end fixed to one side of the L-plate 15 and located below the movable cylinder 19;

[0117] Spring 36 is sleeved on the outside of telescopic rod 35, and one end is fixedly connected to L plate 15;

[0118] Push plate 37 is fixed to the telescopic end of telescopic rod 35 and is fixedly connected to the other end of spring 36;

[0119] The push rod 46 is fixed to one side of the L plate 15 and is located between the movable cylinder 19 and the spring 36.

[0120] Specifically, the upper right corner of the welding head 6 has an inclined angle, the L plate 15 can provide stable support for the telescopic rod 35, the telescopic rod 35 can extend and retract under the action of external force, and can provide support and guidance for the spring 36. The telescopic rod 35 and the spring 36 can provide support for the push plate 37, the L plate 15 can provide support for the top rod 46, and the top rod 46 can provide a blocking and limiting function for the flag plate 38 and the magnet 39, so that the magnet 39 can be easily separated from the movable cylinder 19 after the shovel plate 45 moves to the inclined angle of the upper right corner of the welding head 6.

[0121] The shovel and push assembly includes:

[0122] Flag-shaped plate 38 is fixed to the upper end of push plate 37;

[0123] Magnet 39 is fixedly installed through the flag plate 38 and located on one side of the movable cylinder 19;

[0124] Skateboard 40 is fixed to the lower end of flag plate 38;

[0125] Hollow board 41 is fitted onto the outside of slide plate 40;

[0126] Bolt 42, threaded through the upper wall of hollow plate 41;

[0127] Friction pad 43 is fixed to the lower end of bolt 42 and presses against slide plate 40;

[0128] The spade plate 45 is fixed to the end of the hollow plate 41 away from the slide plate 40 and is located diagonally above the welding head 6.

[0129] Specifically, the T-base 9 has an L-groove 44 on the side near the movable base 13. The spade plate 45 is located in the L-groove 44 and is smaller than the core of the multi-core wire harness so as not to affect the welding positioning and clamping work of the multi-core wire harness. The spade plate 45 is made of silicone to prevent scratching the welding head 6.

[0130] Specifically, the flag plate 38 provides stable support for the magnet 39, the movable cylinder 19 is made of metal and can be magnetically connected to the magnet 39, and the flag plate 38 can provide support for the slide plate 40. The slide plate 40 can provide support for the shovel plate 45 through the hollow plate 41. The hollow plate 41 can provide threaded support for the bolt 42. The bolt 42 can provide support for the friction pad 43. The bolt 42 can use the thread action with the hollow plate 41 to push the friction pad 43 to squeeze and fix the slide plate 40. The elastic force of the spring 36 is smaller than the magnetic force of the magnet 39 adsorbing the movable cylinder 19.

[0131] The transfer assembly further includes:

[0132] The tray 49 is fixed to the left side of the movable seat 13 and located below the right clamp;

[0133] The drawer 50 is set on the front of the outer shell 2 and is located above the tray 49.

[0134] In practical application, the operator can loosen the bolt 42 to adjust the position of the slide plate 40 according to the width of the multi-core wire harness core. This allows the right clamping block 14 to hold and fix the multi-core wire harness core while the movable cylinder 19 and magnet 39 are magnetically connected. The operator can loosen the bolt 42 to separate the friction pad 43 from the slide plate 40, thus releasing the fixation of the slide plate 40 and facilitating the adjustment of the position of the slide plate 40. After adjusting the position, the bolt 42 can be tightened to press the friction pad 43 downwards using the thread action with the hollow plate 41, thereby pressing and fixing the slide plate 40. The drawer box 50 is made of rubber and can deform under external force. It can deform under external force and the resistance of the welding head 6. When the external force disappears, it will rebound to prevent the drawer box 50 from affecting the clamping work of the wire harness.

[0135] When the right clamping block 14 clamps and fixes the cores of the multi-core wire harness, it will drive the movable cylinder 19 to move together, so that one end of the movable cylinder 19 contacts the magnet 39, allowing the magnet 39 to magnetically attract the movable cylinder 19 using magnetic force. After the welding work is completed, the operator needs to first control the extension of the electric push rod 8 to reset the T-base 9 to its original position. Figure 3The position shown aligns the shovel plate 45 with the opening of the L-groove 44. During the descent of the T-base 9, the L-groove 44 provides space for the shovel plate 45 to move, preventing the shovel plate 45 from affecting the descent of the T-base 9. Then, the electric rod 10, electric telescopic rod 12, and electric lifting rod 22 are reset, allowing the right clamping block 14 to move the movable cylinder 19 away from the T-base 9. The movable cylinder 19 uses the magnetic force of the magnet 39 to pull the flag plate 38, push plate 37, slide plate 40, hollow plate 41, bolt 42, friction pad 43, and shovel plate 45 to move towards the right. Simultaneously, the push plate 37, in conjunction with the support of the L-plate 15, compresses the spring 36 and telescopic rod 35 during the movement. At the same time, the shovel plate 45 moves out of the L-groove 44 and moves to the right along the upper end of the welding head 6, scooping up and pushing metal debris and residue on the welding head 6 during the movement. As it moves, the metal debris and residue... The welding head 6 can be moved to the upper right corner of the inclined position and slide down along the inclined angle into the drawer 50 supported by the support plate 49 and the outer shell 2 for temporary storage. At the same time, the magnet 39 and the flag plate 38 will contact the end of the push rod 46, and under the action of the moving external force, the push rod 46 will block the flag plate 38 and the magnet 39, causing the magnet 39 to separate from the movable cylinder 19. Subsequently, the spring 36 will be supported by the L plate 15 and push the flag plate 38 and the magnet 39 to move and reset through the push plate 37, thereby allowing the scraper plate 45 to move and reset. Finally, the operator can pull the drawer 50 forward as needed, so that the drawer 50 can be moved out to the outside through the front of the outer shell 2 under the support of the support plate 49, so that the operator can clean the temporarily stored metal debris and residues. This facilitates the removal of metal debris and residues on the welding head 6 after the wire harness welding work, and prevents the welding effect of the wire harness core from being affected by too much metal debris and residues remaining on the welding head 6.

[0136] As a preferred embodiment of the present invention, a method of using an aviation male multi-core wire harness welding device includes:

[0137] One end of the multi-core wire harness to be stripped is sequentially passed through the movable tube 19 and the sleeve 16, so that one end of the wire harness extends a certain length out of the sleeve 16.

[0138] The electric lifting rod 22 is retracted, and the connecting block 26 and the wire stripper 25 move downward together through the telescopic plate 23, so that the rubber clamp 27 and the rubber seat 20 cooperate to clamp the multi-core wire harness. At the same time, the wire stripper 25 and the semi-ring blade 21 cooperate to cut the outer sheath of the multi-core wire harness, and the pressure rod 33 squeezes the rubber sleeve 29 downward through the pressure plate 34, so that the fine sandpaper 31 adheres to the outside of the wire harness and the sponge 30 adheres to the outside of the wire harness.

[0139] Place the stripped or unstripped cores of the multi-core wire harness onto the soldering head 6;

[0140] The electric telescopic rod 12 is extended, so that the right clamp 14 and the T seat 9 cooperate to clamp the wire core placed on the welding head 6. At the same time, the movable cylinder 19 is driven to move to the left, so that the movable cylinder 19 drives the fixed end of the telescopic plate 23 to move to the left through the electric lifting rod 22, thereby stretching the telescopic plate 23. The rubber clamp 27 and the rubber seat 20 cooperate to pull the multi-core wire harness that needs to be stripped to move to the left together, so that the multi-core wire harness is separated from the outer sheath cut by the wire stripper 25 and the half ring knife 21. At the same time, the wire core passes through the fine sandpaper 31 and the sponge 30 in sequence during the movement. The external force of movement is used to rub against the fine sandpaper 31 to lightly polish the wire core, and the sponge 30 squeezes out the cleaning agent to wipe the surface of the wire core to remove the oxide layer.

[0141] The electric control lever 10 extends, causing the upper clamping block 11 to move to the right and above the clamped wire core;

[0142] The electric actuator 8 is retracted, which drives the upper clamp 11 to move downward through the T-base 9, so that the upper clamp 11 presses down on the wire harness core, making the core tightly attached to the welding head 6.

[0143] The transducer 3 is activated, generating ultrasonic waves that are transmitted to the welding head 6 via the amplitude transformer 4 and welding base 5. The ultrasonic vibration is used to weld the cores of the multi-core aviation male connector wire harness.

[0144] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
