Description

Technical Field

[0001] This utility model relates to the field of headphone winding technology, and more specifically, it relates to a winding device for headphone production. Background Technology

[0002] Existing wired headphones generally consist of two parts: the sound-generating unit and the transmission cable. The transmission cable needs to be connected to the sound-generating unit to form headphones when in use. Therefore, when packaging and selling, the sound-generating unit and the transmission cable are usually placed separately. When packaging the transmission cable, the cable is usually coiled up for easy packaging.

[0003] Patent CN214085155U discloses a winding device for headphone production, including a stand and a base. The stand is disposed on the upper surface of the base, and the base has a feeding component inside. A pair of winding rods are inserted into the outer wall of the stand, and a bracket is fixedly disposed on the outer wall of the stand above the pair of winding rods. A belt pulley is shafted to the top of the bracket, and a winding tape is sleeved on the outer surface of the belt pulley. A first cylinder for driving the pair of winding rods is disposed inside the stand. A set of protruding plates are symmetrically disposed on the outer side of the stand, and a connecting plate is fixedly disposed on the outer wall of each protruding plate. A winding component is fixedly disposed between the two connecting plates.

[0004] The winding device in the above solution avoids the problem of easy knotting during traditional mechanical winding, and significantly reduces the error rate. However, the winding method of this winding device is vertical spiral winding. After the wire is unwound, the wire cannot quickly return to a vertical state due to the long-term packaging restriction.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A winding device for headphone manufacturing, such as Figures 1-4 As shown, the device includes a base 1, a sleeve 2 fixedly connected to the base 1, an electric push rod 3 fixedly connected to the base 1, an extension rod 4 fixedly connected to the telescopic end of the electric push rod 3, a fixing plate 5 fixedly connected to the extension rod 4, a motor 6 fixedly connected to the fixing plate 5, a winding assembly for winding wire at the output end of the motor 6, the winding assembly including a fixing rod 7 fixedly connected to the output end of the motor 6, a positioning post 8 fixedly connected to the fixing rod 7, and an upper mounting plate 9 detachably connected to the positioning post 8, a limiting component for limiting the wire on the fixing rod 7, a lower mounting plate 10 detachably connected to the sleeve 2, a plurality of upper extension blocks 11 and a plurality of lower extension blocks 12 fixedly connected to the upper mounting plate 9 and the lower mounting plate 10 respectively, an adhesive block 13 fixedly connected to the lower extension block 12, and a peelable protective film adhered to the side of the adhesive block 13 near the upper extension block 11.

[0021] like Figures 1-4 As shown, when the wire needs to be wound, the electric push rod 3 can be started first to insert the positioning post 8 into the sleeve 2. Then, the wire end is restricted to the positioning post 8 by the limiting member. Then, the motor 6 can be started to rotate, so that the wire is wound in a flat spiral. After the winding is completed, manual operation is performed. The lower mounting plate 10 is rotated to align the lower extension block 12 with the upper extension block 11. Then, the protective film on the adhesive block 13 is peeled off. Next, the upper extension block 11 is flipped to the side of the lower extension block 12, and then the lower extension block 12 is flipped to the side of the upper extension block 11, so that the adhesive block 13 contacts the upper extension block 11, so that the upper extension block 11 and the lower extension block 12 are adhered together. Then, the upper mounting plate 9 can be pressed manually and the electric push rod 3 can be started to extend. At this time, the limiting member will move away from the wire and no longer contact the wire. Then, the lower mounting plate 10 can be lifted manually to remove the upper mounting plate 9, the wound wire and the lower mounting plate 10, thus completing the winding of the wire.

[0022] like Figure 2 , Figure 4As shown, a number of protrusions 14 are fixedly connected to the fixing rod 7, and the upper mounting plate 9 is provided with a through groove 15 into which the protrusions 14 can be inserted. When installing the upper mounting plate 9, the upper mounting plate 9 can be installed on the fixing rod 7 according to the protrusions 14 and the through groove 15, thereby positioning the upper mounting plate 9. The fixing rod 7 drives the upper mounting plate 9 to rotate, avoiding the upper mounting plate 9 from being rotated by the limiting component, which would cause damage to the appearance of the upper mounting plate 9.

[0023] like Figures 1-3 As shown, the limiting components include a placement cylinder 16 fixedly connected to the fixed rod 7, a sliding rod 17 slidably connected to the placement cylinder 16, a locking block 18 and a lever 19 fixedly connected to both ends of the sliding rod 17, and a fixing block 20 fixedly connected to the middle section of the sliding rod 17. A spring 21 is sleeved between the fixing block 20 and the bottom side of the placement cylinder 16. When it is necessary to limit one end of the wire, the lever 19 can be pulled to drive the sliding rod 17 to slide on the placement cylinder 16. At this time, the fixing block 20 will also slide inside the placement cylinder 16, causing the spring 21 to be deformed into a compressed state. At this time, the locking block 18 will also move away from the sleeve 2. When one end of the wire is inserted between the locking block 18 and the sleeve 2 and the lever 19 is no longer pulled, the spring 21 will reset, causing the locking block 18 to limit one end of the wire.

[0024] like Figures 1-2 As shown, a positioning rod 22 is fixedly connected to the base 1, a guide roller 23 is rotatably connected to the positioning rod 22, and a stop rod 24 is rotatably connected to the positioning rod 22. After fixing one end of the wire, the wire can be placed between the guide roller 23 and the electric push rod 3. Then, the stop rod 24 is rotated so that the stop rod 24 points towards the electric push rod 3 to block the upper side of the wire and prevent the wire from coming off. In this way, the wire can be guided when winding the wire and prevent the wire from rotating with the upper mounting plate 9 and becoming unwindable.

[0025] Working principle: When winding the wire, first activate the electric push rod 3 to insert the positioning post 8 into the sleeve 2. Then, pull the lever 19 to drive the sliding rod 17 to slide on the placement cylinder 16. At this time, the fixing block 20 will also slide inside the placement cylinder 16, causing the spring 21 to be compressed. At this time, the locking block 18 will also move away from the sleeve 2. Then, insert one end of the wire between the locking block 18 and the sleeve 2 and stop pulling the lever 19. The spring 21 will then return to its original position, causing the locking block 18 to restrict one end of the wire, fixing it to the positioning post 8. Then, place the wire between the guide roller 23 and the electric push rod 3. Next, rotate the stop rod 24 so that it points towards the electric push rod 3 to block the upper side of the wire. Then, the electric push rod can be activated. The machine 6 rotates, causing the wire to be wound in a flat spiral. After winding, manual operation is performed. The lower mounting plate 10 is rotated to align the lower extension block 12 with the upper extension block 11. Then, the protective film on the adhesive block 13 is peeled off. Next, the upper extension block 11 is flipped to the side of the lower extension block 12, and then the lower extension block 12 is flipped to the side of the upper extension block 11, so that the adhesive block 13 contacts the upper extension block 11, making the upper extension block 11 and the lower extension block 12 stick together. Then, the upper mounting plate 9 can be pressed manually and the electric push rod 3 can be activated to extend. At this time, the limiting part will move away from the wire and no longer contact the wire. Then, the lower mounting plate 10 can be lifted manually to remove the upper mounting plate 9, the wound wire, and the lower mounting plate 10, thus completing the winding of the wire.
