Description

Technical Field

[0001] This invention relates to the field of headphone cable winding technology, and more particularly to an automatic headphone cable feeding and winding device. Background Technology

[0002] When the headphones are manufactured, the headphone wires need to be neatly wound up for easy packaging and to improve the appearance of the wires.

[0003] Patent publication number CN102238451A discloses an earphone cable winder, characterized by comprising a housing, a rotating rod, and a rotating rod driving device; the rotating rod is located in the center of the housing and connected to the housing via a rotating shaft. The rotating driving device is located on the reverse side of the housing and is fixedly connected to the rotating rod via a rotating shaft.

[0004] The aforementioned patent directly winds the headphone cable onto two cylinders, without evenly arranging the cable or pressing it down. This results in the cable becoming loose and the overall appearance of the winding being relatively poor. To address this issue, we have designed an automatic feeding and winding device for headphone cables that features both even cable arrangement and pressing functions. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies that cannot uniformly wind headphone cables and cannot compress wound headphone cables, this invention provides an automatic feeding and winding device for headphone cables with uniform winding and compression functions.

[0006] An automatic headphone cable feeding and winding device includes a winding base, an electric push rod, and a motor. The electric push rod is installed on the left side of the middle part of the winding base, and the motor is installed on the right side of the middle part of the winding base. It also includes an arranging mechanism and a pressing mechanism. The motor housing is provided with an arranging mechanism for uniformly winding the headphone cable, and the winding base is provided with a pressing mechanism for pressing down the wound headphone cable.

[0007] As a further preferred embodiment, the arrangement mechanism includes a cable tube, a retaining ring, and an arrangement assembly. The cable tube for winding the headphone cable is snapped onto the output shaft of the motor. The retaining ring is fixed to the electric push rod and contacts the left side of the motor output shaft. An arrangement assembly for evenly winding the headphone cable onto the cable tube is provided on the rear side of the middle of the winding base.

[0008] As a further preferred embodiment, the arrangement assembly includes an arrangement plate, a support rod, a limiting plate, an upper compression spring, a lower compression spring, and a support plate. The motor's output shaft has a groove for the headphone cable head to move. The cable guide tube has an insertion port corresponding to the groove on the motor's output shaft. A limiting plate is installed on the rear side of the middle section of the winding base. A support rod is slidably connected to the rear side of the middle section of the winding base. An arrangement plate is installed on the top of the support rod. The arrangement plate has evenly spaced arc-shaped grooves on the side near the cable guide tube. The lower rear part of the arrangement plate engages with the limiting plate. A support plate is slidably connected to the upper rear side of the middle section of the winding base. A support plate is also slidably connected to the lower rear side of the middle section of the winding base. An upper compression spring is connected between the upper support plate and the winding base, and the upper compression spring is wound around the upper support plate. A lower compression spring is connected between the lower support plate and the winding base, and the lower compression spring is wound around the lower support plate.

[0009] As a further preferred embodiment, the clamping mechanism includes a pressure plate and a return spring. A pressure plate for pressing down the wound headphone wire is slidably connected to the lower left side of the motor housing. Multiple return springs are wound around the lower part of the pressure plate, and the upper and lower ends of the return springs are respectively connected to the pressure plate and the motor housing.

[0010] As a further preferred embodiment, a clamping mechanism is also included to prevent the headphone cable from unraveling when the wound headphone cable is removed. The clamping mechanism includes a telescopic clamping frame, a rear tension spring, clamping rods, and a front tension spring. The telescopic clamping frame is engaged between the left side of the motor housing and the right side of the fixing ring. The telescopic clamping frame is telescopically connected between its front and rear sides and between its left and right sides. The middle of the front and rear sides of the telescopic clamping frame is wound with a rear tension spring. The left and right sides of the rear tension spring are respectively connected to the left and right sides of the telescopic clamping frame. The middle of the left side of the telescopic clamping frame is wound with a front tension spring. The front and rear ends of the front tension spring are respectively connected to the front and rear parts of the left side of the telescopic clamping frame. A fixing ring is installed on the electric push rod. The front and rear parts of the right side of the fixing ring are symmetrically installed with clamping rods. The front and rear clamping rods respectively contact the front and rear sides of the upper part of the telescopic clamping frame.

[0011] As a further preferred embodiment, it also includes a guiding mechanism for guiding the headphone cable during the winding process. The guiding mechanism includes a lower guide bracket, an upper guide bracket, a guide wheel, and a guide spring. The lower guide bracket is installed in the middle of the front part of the winding base. The upper guide bracket is slidably connected to the upper part of the lower guide bracket. The guide wheel is rotatably connected to the upper part of the lower guide bracket. The guide wheel is also rotatably connected to the upper guide bracket. The guide wheels on the upper and lower sides are in contact with each other. Guide springs are wound on the left and right sides of the lower part of the upper guide bracket. The upper and lower ends of the guide springs are respectively connected to the upper guide bracket and the lower guide bracket.

[0012] As a further preferred embodiment, it also includes a wire clamping mechanism for clamping the headphone cable end. The wire clamping mechanism includes a wire clamping cover and a helical spring. The wire clamping cover is symmetrically and slidably connected to the front and rear parts of the right side of the cable tube. A helical spring is wound on each wire clamping cover. The inner and outer ends of the helical spring are respectively connected to the wire clamping cover and the cable tube.

[0013] As a further preferred option, a baffle is also included. The baffle is evenly installed around the left side of the cable tube. Before the telescopic clamp retracts and clamps the wound headphone wire, the baffle prevents the headphone wire from slipping off the left side of the cable tube.

[0014] The beneficial effects of this invention are as follows: 1. Through the elastic force of the upper and lower compression springs, the arranging plate presses down on the headphone wire and guides the headphone wire, so that the headphone wire is evenly laid on the ribbon tube, which is conducive to the neat winding of the headphone wire. 2. The spring force of the return spring can make the pressure plate press the wound headphone wire tightly, preventing the wound headphone wire from loosening and keeping the wound headphone wire in a neat state. 3. The telescopic clamping frame retracts due to the elastic force of the rear tension spring and the front return spring. The retraction of the telescopic clamping frame can clamp the wound headphone cable, thereby enhancing the stability of the wound headphone cable. 4. By passing the headphone cable through the middle of the upper and lower guide brackets, the headphone cable can be guided, preventing it from bending and being damaged, and facilitating the smooth and safe winding of the headphone cable. 5. The elastic force of the spiral spring can clamp the headphone cable end with the clip, thereby preventing the headphone cable end from slipping out and facilitating stable winding of the headphone cable; 6. Before the telescopic clamp retracts to clamp the wound headphone cable, the baffle prevents the headphone cable from slipping off the left side of the cable guide tube, maintaining the wound state of the headphone cable and facilitating neat winding of the headphone cable.

Detailed Implementation

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0031] Example 1 An automatic wire feeding and winding device for headphone cables, such as Figure 1 and Figure 2As shown, it includes a winding base 1, an electric push rod 2, a motor 3, an arranging mechanism 4, and a pressing mechanism 5. The electric push rod 2 is fixed to the left side of the middle part of the winding base 1, and the motor 3 is installed on the right side of the middle part of the winding base 1 by screws. The arranging mechanism 4 is provided on the housing of the motor 3. The arranging mechanism 4 is used to evenly wind the headphone wire. The pressing mechanism 5 is provided on the winding base 1. The pressing mechanism 5 is used to press down the wound headphone wire.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the arranging mechanism 4 includes an arranging plate 41, a support rod 42, a limiting plate 43, an upper compression spring 44, a lower compression spring 45, a cable guide tube 46, a support plate 47, and a fixing ring 48. The cable guide tube 46 is snapped onto the output shaft of the motor 3 and is used to wind the headphone cable. The output shaft of the motor 3 has a groove for the headphone cable head to move, and the cable guide tube 46 has an insertion port corresponding to the groove on the output shaft of the motor 3. The limiting plate 43 is welded to the rear side of the middle of the winding base 1. The support rod 42 is slidably connected to the rear side of the middle of the winding base 1. The arranging plate 41 is welded to the top of the support rod 42. The arranging plate 41 is located near the cable guide tube 46. The sides are evenly spaced with arc-shaped grooves. The lower rear part of the arrangement plate 41 engages with the limiting plate 43. There are two support plates 47. One support plate 47 is slidably connected to the upper rear side of the middle part of the winding base 1, and the other support plate 47 is slidably connected to the lower rear side of the middle part of the winding base 1. The upper compression spring 44 is fixed between the upper support plate 47 and the winding base 1 and is wound on the upper support plate 47. The lower compression spring 45 is fixed between the lower support plate 47 and the winding base 1 and is wound on the lower support plate 47. A fixing ring 48 is fixedly connected to the electric push rod 2 and contacts the left side of the output shaft of the motor 3.

[0033] like Figure 1 , Figure 2 and Figure 6 As shown, the clamping mechanism 5 includes a pressure plate 51 and a return spring 52. The pressure plate 51 is slidably connected to the lower left side of the motor 3 housing. The pressure plate 51 is used to press down the wound headphone wire. Three return springs 52 are wound around the lower part of the pressure plate 51. The upper and lower ends of the return springs 52 are respectively connected to the pressure plate 51 and the motor 3 housing.

[0034] When it is necessary to wind the headphone cable, the headphone cable end is first placed on the rightmost side of the groove on the cable guide tube 46 and the output shaft of the motor 3, and then the motor 3 is started. The output shaft of the motor 3 rotates, causing the cable guide tube 46 to rotate. The rotation of the cable guide tube 46 winds the headphone cable. During the winding process, the headphone cable presses against the arranging plate 41, which slides adaptively. The elastic force of the upper compression spring 44 and the lower compression spring 45 causes the arranging plate 41 to press down on the headphone cable, and the arranging plate 41 guides the headphone cable, so that the headphone cable is evenly laid on the cable guide tube 46 from right to left. After the headphone cable completes one turn of winding on the cable guide tube 46, it is guided by the arranging plate 41. The headphone cable is wound from right to left onto the ribbon cable tube 46. By repeatedly winding the headphone cable back and forth on the ribbon cable tube 46, the headphone cable can be completely wound onto the ribbon cable tube 46. In addition, during the winding process, the elastic force of the return spring 52 causes the pressure plate 51 to press the wound headphone cable tightly, thereby preventing the wound headphone cable from loosening. When the headphone cable is wound, the motor 3 is turned off, and the telescopic part of the electric push rod 2 is controlled to retract, thereby moving the fixing ring 48 to the left and disengaging it from the output shaft of the motor 3. Then the ribbon cable tube 46 can be removed, and the wound headphone cable can be taken away. Then the fixing ring 48 is reset by the electric push rod 2, and then the electric push rod 2 is turned off.

[0035] Example 2 Based on Example 1, such as Figure 1 , Figure 7 , Figure 8 and Figure 9 As shown, it also includes a clamping mechanism 6, which is used to prevent the headphone wire from unraveling when the wound headphone wire is removed. The clamping mechanism 6 includes a telescopic clamping frame 61, a rear tension spring 62, a clamping rod 63, and a front tension spring 64. The telescopic clamping frame 61 is snapped between the left side of the motor housing 3 and the right side of the fixing ring 48. The telescopic clamping frame 61 is telescopically connected between the front and rear sides and between the left and right sides. There are two rear tension springs 62, which are respectively wrapped around the middle of the front and rear sides of the telescopic clamping frame 61. The left and right sides of the rear tension springs 62 are respectively connected to the left and right sides of the telescopic clamping frame 61. The front tension spring 64 is wrapped around the middle of the left side of the telescopic clamping frame 61. The front and rear ends of the front tension spring 64 are respectively connected to the front and rear parts of the left side of the telescopic clamping frame 61. The clamping rods 63 are symmetrically welded to the front and rear parts of the right side of the fixing ring 48. The clamping rods 63 on the front and rear sides are respectively in contact with the front and rear sides of the upper part of the telescopic clamping frame 61.

[0036] Initially, the rear tension spring 62 is stretched. During the winding of the headphone cable, the wound headphone cable is located in the middle of the telescopic clamping frame 61. The fixed ring 48 moves to the left, causing the clamping rod 63 to move to the left. The clamping rod 63 moves to the left, squeezing the telescopic clamping frame 61 to open. The front tension spring 64 is stretched. When the clamping rod 63 moves to the left and disengages from the output shaft of the telescopic clamping frame 61, the elastic force of the rear tension spring 62 and the front return spring 52 causes the telescopic clamping frame 61 to contract, thereby clamping the wound headphone cable and enhancing the stability of the wound headphone cable.

[0037] like Figure 1 , Figure 2 and Figure 10 As shown, it also includes a guide mechanism 7, which is used to guide the headphone cable during the winding process. The guide mechanism 7 includes a lower guide bracket 71, an upper guide bracket 72, guide wheels 73, and guide springs 74. The lower guide bracket 71 is welded to the middle of the front part of the winding base 1. The upper guide bracket 72 is slidably connected to the upper part of the lower guide bracket 71. There are two guide wheels 73. One guide wheel 73 is installed on the upper part of the lower guide bracket 71 through a bearing, and the other guide wheel 73 is installed on the upper guide bracket 72 through a bearing. The upper and lower guide wheels 73 are in contact with each other. There are two guide springs 74. The two guide springs 74 are respectively wound around the left and right sides of the lower part of the upper guide bracket 72. The upper and lower ends of the guide springs 74 are respectively connected to the upper guide bracket 72 and the lower guide bracket 71.

[0038] Before securing the headphone cable end to the far right of the groove on the output shaft of motor 3, pass the headphone cable between the upper guide bracket 72 and the lower guide bracket 71. This guides the headphone cable and prevents it from bending and being damaged. During the winding of the headphone cable, the elastic force of the guide spring 74 keeps the upper guide bracket 72 and the lower guide bracket 71 in close contact, maintaining their guiding effect on the headphone cable.

[0039] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes a wire clamping mechanism 8, which includes a wire clamping cover 81 and a spiral spring 82. There are two wire clamping covers 81, which are slidably connected to the front and rear parts of the right side of the cable tray 46. There are two spiral springs 82, which are wound around the two wire clamping covers 81 respectively. The inner and outer ends of the spiral springs 82 are connected to the wire clamping cover 81 and the cable tray 46 respectively.

[0040] When the headphone cable end is secured in the rightmost groove on the output shaft of motor 3, the headphone cable end is inserted between the clamping covers 81. The headphone cable end squeezes the clamping covers 81 and moves outward, compressing the coil spring 82. Subsequently, the elastic force of the coil spring 82 causes the clamping covers 81 to clamp the headphone cable end, thus preventing the headphone cable end from slipping out. This ensures stable winding of the headphone cable during the winding process.

[0041] like Figure 2 , Figure 13 and Figure 14 As shown, it also includes a baffle 9, and the baffle 9 is uniformly welded to the left side of the cable conduit 46.

[0042] During the winding of the headphone cable, the headphone cable is wound on the right side of the baffle 9 due to the blocking effect of the baffle 9. Before the telescopic clamping bracket 61 retracts to clamp the wound headphone cable, the baffle 9 can prevent the headphone cable from slipping off the left side of the cable tube 46, thus maintaining the state of the headphone cable being wound.

[0043] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
