Description

Technical Field

[0001] This invention relates to the field of coil winding technology, and in particular to a fully automatic multi-coil high-precision winding device and its winding method. Background Technology

[0002] With the development of technology, electronic devices such as game consoles are gradually moving towards innovation, which requires them to achieve diversified functions and intelligence. As an important component inside game consoles, communication coils also face technical challenges, needing to achieve efficient communication functions within a limited space without affecting the normal operation of other components.

[0003] Most equipment can only wind a single coil independently, making it difficult to continuously wind and form multiple coils without stopping the machine or changing the mold, resulting in low production efficiency and complex processes.

[0004] Therefore, there is an urgent need in this field for a winding device that can realize continuous winding of multiple coils, high-precision wire arrangement and lead wire control, and automatic wire shaping, so as to meet the urgent needs of modern precision electronic manufacturing for high-performance, high-consistency and high-efficiency production of coils. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic multi-coil high-precision winding equipment and its winding method, which realizes multi-coil connection, lead wire control, precision wire arrangement, non-destructive winding, accurate positioning, and stable mass production, thereby meeting customer needs.

[0006] To achieve the above objectives, the present invention provides a fully automatic multi-coil high-precision winding device and its winding method, comprising a wire feeding mechanism, a wire arranging mechanism, a spindle mechanism, a wire cutting mechanism, a material handling mechanism, a heating mechanism, and a chassis, all mounted on a substrate. The wire feeding mechanism outputs wire to the wire arranging mechanism. The wire arranging mechanism includes a horizontal wire feeding assembly and a vertical moving assembly. The vertical moving assembly controls the vertical movement of the horizontal wire feeding assembly, which outputs wire to the spindle mechanism. The spindle mechanism includes an upper spindle mechanism and a lower spindle mechanism for winding operations. The wire cutting mechanism cuts the wire between the wire arranging mechanism and the upper spindle mechanism after winding is completed. The heating mechanism heats and shapes the outer surface of the wire. The material handling mechanism moves the wound coil to the next station. A controller within the chassis controls the wire feeding mechanism, the wire arranging mechanism, the spindle mechanism, the wire cutting mechanism, the material handling mechanism, and the heating mechanism.

[0007] Preferably, the wire feeding mechanism includes a wire feeding cover assembly and a tensioner assembly disposed on the substrate. The tensioner assembly includes a servo tensioner and a tension frame. The wire feeding cover assembly stably feeds the product raw material wire. The bottom of the tensioner assembly is fixed to the substrate by bolts, and the top of the tensioner assembly is fixed with a servo tensioner. The servo tensioner can actively feed the wire and ensure stable tension.

[0008] Preferably, the horizontal wire feeding assembly includes a wire inlet roller and a wire guide needle.

The output end of the upper rotating shaft assembly is fixed to the inner ring of the mold sleeve to realize the rotation of the mold sleeve.

[0011] The mold core feeding drive assembly includes a mold core feeding drive motor, a feeding support plate, and a mold core pushing screw. The mold core feeding drive motor is fixed on the feeding support plate and is driven by the mold core pushing screw. The mold core pushing screw includes a mold core first pushing screw and a mold core third pushing screw. The mold core first pushing screw is driven by the mold core first in the upper mold assembly, and the mold core third pushing screw is driven by the mold core third in the upper mold assembly.

[0012] The first fan-shaped mold cover is fixed to the mold sleeve. The mold sleeve has two fan-shaped holes. The first fan-shaped mold cover and the second fan-shaped mold cover pass through the fan-shaped holes and are slidably fitted to the mold sleeve.

[0013] The center of each of the three fan-shaped mold covers has a slotted hole. The mold cores 1, 2, and 3 are respectively inserted into the slotted holes of the three fan-shaped mold covers. The mold core 2 is fixed to the fan-shaped mold cover 2.

[0014] Preferably, the mold sleeve has a wire inlet groove on its side wall, and a wire hook and a wire block are fixedly connected to the side wall of the mold sleeve. The wire hook is located at the wire inlet groove of the mold sleeve, and the wire block is located at the wire outlet of the mold sleeve.

[0015] Preferably, the upper mold assembly further includes a wire pressing pin and a wire cutting pin. The wire pressing pin is installed at the tail end of the mold sleeve and supported by a spring at the tail end of the mold sleeve and a round hole on the mold sleeve. At the beginning of winding, the wire is hooked into the wire pressing pin, and the wire pressing pin pushes forward to press down the lead wire head, cooperating with the mold sleeve to rotate and wind the wire. A wire cutting pin is connected next to the wire pressing pin. The wire cutting pin is fixed to the mold sleeve by its surface groove. After the winding is completed, the wire cutting pin pushes forward to cut off the coiled lead wire.

[0016] Preferably, the lower spindle mechanism includes a lower rotating shaft assembly, a support member, and a lower spindle feed drive assembly. A support rod is provided on the support member, which provides support for the lower rotating shaft assembly and the lower spindle feed drive assembly. The lower spindle feed drive assembly includes a lower spindle feed drive motor and a lead screw connected together. The lead screw is pushed to control the longitudinal movement of the lower mold cover, and the lower rotating shaft assembly controls the rotation of the lower mold cover. The lower mold cover rotates at the same frequency as the mold sleeve.

[0017] Preferably, the mold core one, mold core two, and mold core three are in contact with each other on the lower mold cover.

[0018] Preferably, the wire cutting mechanism includes pneumatic scissors and a scissor pushing assembly. The scissor pushing assembly is fixed on the left side of the base. After the winding is completed, the pushing cylinder pushes the pneumatic scissors to extend between the wire feeding needle and the mold to cut off the lead wire.

[0019] The heating mechanism includes a hot air gun and a hot air gun propulsion assembly. The hot air gun propulsion assembly is fixed on the base. The hot air gun propulsion assembly horizontally propels the hot air gun closer to the winding working area. The hot air gun provides a sufficient temperature environment. At the same time, the hot air gun retracts to avoid interference during the process of the flipping material picking mechanism picking up the material.

[0020] The material handling mechanism includes a material handling fixture, a horizontal traversing assembly, and a vertical lifting assembly. The support plate on the horizontal traversing assembly mounts the entire flipping material handling mechanism on the right side of the base. Both the horizontal traversing assembly and the vertical lifting assembly use lead screw modules. The material handling fixture can be flipped under the action of the rear rotary cylinder, and the material is picked up from the upper mold by vacuum suction.

[0021] A winding method for a fully automated multi-coil high-precision winding device includes the following steps:

[0022] Step 1: Tensioner releases the wire. The wire passes through the tensioner on the wire release mechanism and enters the wire laying mechanism downwards.

[0023] Step 2: The wire enters the cable laying mechanism. The wire passes through the infeed roller of the cable laying mechanism and enters the cable laying guide pin on the right end. Then, the wire is pressed in by the wire pressing pin.

[0024] Step 3: Prepare for winding. The longitudinal moving component of the wire laying structure drives the wire laying guide pin to move down, while the wire is fed horizontally and pulled into the lead wire through the hanging hook. The mold core one extends out of the mold sleeve under the action of the mold core feeding drive component. The mold sleeve rotates, and the hanging hook rotates to the opposite side of the wire laying guide pin. The wire is close to the long side of the mold core one. The lower mold cover rises under the drive of the lower spindle feeding drive component and closes with the mold sleeve.

[0025] Step four: Start winding. The upper and lower rotating shaft assemblies drive the upper and lower rotating shafts to rotate clockwise at high speed to wind the first coil. The wire guide pins are driven by the longitudinal movement assembly of the wire winding mechanism to wind the wire on the mold core one. The wire is wound around the mold core one. After winding a certain number of turns, the lower mold is driven to descend by the lower main shaft feed drive assembly to open the mold. At the same time, the mold core one is retracted into the mold sleeve under the action of the mold core feed drive assembly.

[0026] Afterwards, the wire guide pin moves upward, the mold sleeve rotates counterclockwise to a fixed angle, the wire is close to the long side of the second mold core, and the lower mold cover rises under the drive of the lower spindle feed drive assembly to close the mold; the rotating assembly drives the upper and lower rotating shafts to rotate clockwise at high speed to wind the second coil. After winding a certain number of turns, the lower mold descends under the drive of the lower spindle feed drive assembly to open the mold; the third mold extends out of the mold sleeve under the action of the mold core feed drive assembly, the mold rotates clockwise to a fixed angle, and the wire is close to the long side of the third mold core; the hot air gun push assembly in the heating mechanism pushes the hot air gun into the winding working area, the winding mechanism rotates clockwise, the hot air gun heats up, melts the surface of the wire, and shapes the wire.

[0027] Step 5: Flip and pick up the material. The lower mold is driven to descend by the lower spindle feed drive assembly to open the mold. The horizontal traverse assembly drives the material pick-up fixture to move horizontally and enter the winding work area. The material pick-up fixture flips under the action of the rear rotary cylinder. The vertical lifting assembly works with the material pick-up fixture to pick up the finished product on the upper mold. The finished product is transferred by vacuum suction. Flip again, release the vacuum and unload to the rear station.

[0028] The advantages and positive effects of the fully automatic multi-coil high-precision winding equipment described in this invention are:

[0029] This invention, by setting up the coordinated operation of the upper spindle mechanism, the lower spindle mechanism, and the wire winding mechanism, combined with two independently retractable mold cores and a fixed mold core structure, and with the help of wire cutting pins and wire pressing pins, can sequentially complete the winding of three coils in a single clamping and continuous process without changing the mold, which significantly improves production efficiency and equipment integration.

The material handling fixture 71 can be tilted by a rear-end rotary cylinder, and material is handled from the upper mold by vacuum suction.

[0079] This invention discloses a winding method for a fully automatic multi-coil high-precision winding device, comprising the following steps:

[0080] Step 1: The tensioner releases the wire, which then passes through the tensioner on the wire release mechanism 2 and enters the wire laying mechanism 3.

[0081] Step 2: The wire enters the cable laying mechanism 3. The wire passes through the infeed roller 311 of the cable laying mechanism 3 and enters the cable laying guide pin on the right end. Then, the wire is pressed by the wire pressing pin 4138.

[0082] Step 3: Prepare for winding. The longitudinal moving component 32 of the winding structure drives the winding guide pin to move downward, while simultaneously feeding the wire horizontally. The wire is pulled in and passes through the hanging hook 4137. The mold core 41341 extends out of the mold sleeve 4135 under the action of the mold core feed drive component 412. The mold sleeve 4135 rotates, and the hanging hook 4137 rotates to the opposite side of the winding guide pin. The wire is close to the long side of the mold core 41341. The lower mold cover 434 rises under the drive of the lower spindle feed drive component 433 and closes with the mold sleeve 4135.

[0083] Step four: Begin winding. The upper rotating shaft assembly 411 and the lower rotating shaft assembly 431 drive the upper and lower rotating shafts to rotate clockwise at high speed, respectively, to wind the first coil. The wire guide pin, driven by the longitudinal movement assembly 32 of the wire winding mechanism 3, winds the wire onto the mold core 41341, and the wire winds around the mold core 41341. After winding a certain number of turns, the lower mold, driven by the lower main shaft feed drive assembly 433, descends to open the mold. Simultaneously, the mold core retracts into the mold sleeve 4135 under the action of the mold core feed drive assembly 412.

[0084] Afterwards, the wire guide pin moves upward, the mold sleeve 4135 rotates counterclockwise to a fixed angle, and the wire is close to the long side of the mold core 41342. The lower mold cover 434 rises under the drive of the lower spindle feed drive assembly 433 to close the mold. The rotating assembly drives the upper and lower rotating shafts to rotate clockwise at high speed to wind the second coil. After winding a certain number of turns, the lower mold descends under the drive of the lower spindle feed drive assembly 433 to open the mold. The mold three extends out of the mold sleeve 4135 under the action of the mold core feed drive assembly 412, and the mold rotates clockwise to a fixed angle, with the wire close to the long side of the mold core 41343. The hot air gun push assembly 62 in the heating mechanism 6 pushes the hot air gun into the winding working area, the winding mechanism rotates clockwise, the hot air gun heats up, melts the surface of the wire, and shapes the wire.

[0085] Step 5: Flip and pick up the material. The lower mold is driven to descend by the lower spindle feed drive assembly 433 to open the mold. The horizontal lateral movement assembly 73 drives the material pick-up fixture 71 to move laterally and enter the winding working area. The material pick-up fixture 71 is flipped under the action of the rear rotary cylinder. The vertical lifting assembly 72 works with the material pick-up fixture 71 to pick up the finished product on the upper mold. The finished product is transferred by vacuum suction. Flip again, release the vacuum and unload to the rear station.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
