Description

Technical Field

[0001] This invention relates to the field of speaker wire stranding technology, and more specifically to an automatic speaker wire winding and coiling machine. Background Technology

[0002] Some loudspeakers have requested stranded wires, that is, two leads are hinged together into one hinged wire, thus creating new requirements for improvements to the equipment used in manufacturing loudspeakers.

[0003] Most products' hinged cables are made by first twisting the wire into stranded wire and then cutting it into segments for use. However, speaker wires are soldered first and then hinged. Therefore, it is impossible to achieve one-time hinged wiring, which presents at least the following difficulties:

[0004] 1. The speaker wires are thin and flexible; how can the wire ends be accurately connected?

[0005] 2. Since the wires are twisted after welding, how can damage be prevented at the weld points?

[0006] Therefore, it is necessary to develop a specialized wire twisting device for loudspeakers to complete the wire twisting process. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic speaker wire winding machine for accurately completing wire connection and preventing damage to the solder joints.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic speaker wire winding machine includes a wire winding mechanism corresponding to a wire winding fixture position. The wire winding mechanism includes a wire clamp for holding the wire to be wound and a wire winding drive unit for driving the wire clamp to rotate and winding the wire. It also includes:

[0010] A wire-leading mechanism, comprising a wire-leading clamp and a wire-leading driver, wherein the wire-leading clamp reciprocates between the stranding fixture and the stranding clamp under the drive of the wire-leading driver, and the wire-leading clamp is provided with a wire-leading groove for combing the wire to be stranded;

[0011] A wire pressing mechanism is provided between the lead wire clamp and the stranding fixture, and is located on the side where the stranding fixture is located. The wire pressing mechanism includes an upper pressing plate, a lower pressing plate, and a wire pressing drive unit that drives the upper pressing plate and the lower pressing plate to press the wire in opposite directions.

[0012] Sequentially, the lead clamp opens and moves to the side where the stranding fixture is located, the stranding fixture enters the stranding fixture position, the wire pressing drive unit drives the upper pressure plate and the lower pressure plate to press the wire to be stranded, the lead clamp closes and pulls one end of the wire to be stranded to the strand clamp, the strand clamp holds the wire to be stranded, and the lead clamp opens and returns to the side where the stranding fixture is located.

[0013] Furthermore, when the lead clamp is in the closed state, its upper clamp plate and lower clamp plate are offset, and the lead groove is formed on the upper clamp plate and the lower clamp plate.

[0014] Furthermore, the pressure mechanism also includes a tooling pressure plate, which follows the upper pressure plate, and a tooling pressure column and a speaker pressure column are elastically installed in the tooling pressure plate.

[0015] Furthermore, the stranding clamp includes a pull rod seat, a pull rod, a clamping spring, and a four-bar clamp. The first end of the pull rod is rotatably and axially slidably inserted into the pull rod seat. The second end of the pull rod extends out of the pull rod seat and forms a tension boss. The four-bar clamp is connected to the first end of the pull rod. The clamping spring is sleeved on the pull rod and located between the pull rod seat and the four-bar clamp. The maximum elastic force of the clamping spring is calibrated through a damage test of the strand to be stranded. The stranding drive unit includes a synchronous pulley, a synchronous belt, a stranding motor, a release cylinder, and a pull plate. The synchronous pulley is coaxially nested on the pull rod. The stranding motor drives the synchronous pulley to rotate through the synchronous belt. The pull plate has a pull groove corresponding to the boss. The release cylinder drives the pull plate to pull the tension boss.

[0016] Furthermore, it also includes a tooling track, in which the stranded wire tooling is positioned and slidably transported along the tooling track.

[0017] Furthermore, it also includes a tooling transfer mechanism, which includes a slide cylinder, a transfer cylinder, and a transfer block. The slide cylinder is located below the tooling track, and the transfer cylinder is mounted on the slide cylinder and drives the transfer block to rise and fall. The bottom of the tooling track is provided with a clearance groove for the transfer block to slide, and a clamping platform corresponding to the transfer block is provided below the stranding tooling.

[0018] Furthermore, it also includes a receiving mechanism, which includes a transfer unit and a receiving unit. The transfer unit is located above the tooling track to transfer the loudspeakers on the stranded wire tooling that are passing through. The receiving unit is located on one side of the tooling track and includes a tray for receiving the loudspeakers transferred by the transfer unit.

[0019] Furthermore, with the tooling track as the X-axis, the transfer unit includes a YZ-axis transfer device, a rotary driver, and a transfer head. The transfer head is mounted on the transfer device via the rotary driver. The receiving unit also includes an X-axis transfer device to drive the material tray to move along the X-axis. When the YZ-axis transfer device moves towards the tooling track to pick up material, the rotary driver rotates the transfer head in the X-axis direction. When the YZ-axis transfer device moves towards the material tray to unload material, the rotary driver rotates the transfer head in the Y-axis direction. Each time the transfer head unloads material, the material tray is fed along the X-axis once.

[0020] Furthermore, the surface of the tray is flat and magnetically attracts the speaker; the transfer head includes an inverted U-shaped base, a magnetic strip and a magnetic strip lifting driver, the underside of the inverted U-shaped base forms a pressure surface that presses down on the edge of the speaker, and the magnetic strip lifting driver is disposed on the inverted U-shaped base to drive the magnetic strip to move up and down in the inverted U-shaped base.

[0021] Furthermore, the receiving unit also includes a frame, a tray lifting driver, and a tray support. The frame includes four angle irons facing each other to correspond to the four corners of the tray. The Y-axis gap of the angle irons forms a receiving channel on the X-axis. The tray lifting driver is located below the receiving channel. The tray supports are a pair and facing each other towards the receiving channel. Each tray support includes a Y-axis driver and a support plate mounted on the Y-axis driver. When the tray is fully entered into the receiving channel, the tray lifting driver drives the tray to rise, and the tray support drives the support plate to support the tray. Then, the tray lifting driver resets to clear the receiving channel, waiting for the next receiving cycle.

[0022] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] 1. The present invention includes a lead wire mechanism and a wire pressing mechanism that cooperates with the lead wire mechanism. After the stranding fixture enters the stranding fixture position, the wire pressing mechanism clamps the end of the wire to be stranded on the side where the solder joint is located. Then the lead wire clamp closes and moves along the direction of the stranding clamp. In this way, the lead wire mechanism allows the thinner and softer wire to be stranded to be smoothly connected by the stranding clamp. At the same time, the clamping of the wire pressing mechanism prevents the lead wire and stranding process from damaging the solder joint, which would cause the wire to be stranded to fall off or loosen from the solder joint.

[0024] 2. The present invention sets the lead clamps as staggered clamps, which makes it easy to adjust the clamping gap and force, making it easy to straighten the wire to be twisted and less likely to damage the wire.

[0025] 3. The stranded wire fixture of the present invention uses the fixture pressure column to elastically press the speaker body, which compensates for the difference between the pressing distance and the clamping distance between the upper and lower pressure plates, making it easy to adjust the pressing force of the upper and lower pressure plates.

[0026] 4. The stranding clamp of the present invention achieves integrated control of multiple stranding clamps through synchronous belt drive and release cylinder release, which facilitates batch stranding of loudspeakers; at the same time, its clamping is achieved by clamping spring, and the maximum elastic force of the clamping spring is calibrated by the damage test of the wire to be stranded, so that when the hinge force applied to the wire to be stranded is too large and will damage the wire to be stranded, the wire to be stranded can be detached from the clamping spring.

[0027] 5. The transfer unit of the present invention rotates the transfer head by a rotary driver, switching the material picking direction and the material unloading direction of the transfer head, thereby arranging the speaker on the material tray along the Y-axis. In conjunction with the X-axis feeding of the material tray, the unloading efficiency can be improved.

[0028] 6. The transfer head of the present invention, through the cooperation of the inverted U-shaped base and the magnetic strip, makes it difficult for the speaker to shift on the tray during unloading. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Furthermore, it should be noted that:

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example

[0055] Please refer to Figure 1-3 As shown, the present invention discloses an automatic speaker wire winding and coiling machine, including a wire winding mechanism 200, a wire leading mechanism 300, and a wire pressing mechanism 400.

[0056] The stranding mechanism 200 is set in relation to the stranding fixture position 110. Please refer to [reference needed]. Figures 7-9 As shown, the stranding mechanism 200 includes a stranding clamp 210 for holding the wire to be stranded and a stranding drive unit 220 for driving the stranding clamp 210 to rotate and strand the wire.

[0057] Please refer to Figure 4 As shown, the wire leading mechanism 300 includes a wire clamp 310 and a wire driver 320. The wire clamp 310 moves back and forth between the stranding fixture 110 and the stranding clamp 210 under the drive of the wire driver 320. The wire clamp 310 is provided with a wire groove 311 for combing the wire to be stranded.

[0058] Please refer to Figure 5 and Figure 6As shown, the wire pressing mechanism 400 is located between the lead wire clamp 310 and the stranding fixture 110, and is located on the side where the stranding fixture 110 is located. The wire pressing mechanism 400 includes an upper pressing plate 410, a lower pressing plate 420 and a wire pressing drive unit that drives the upper pressing plate 410 and the lower pressing plate 420 to press the wires in opposite directions.

[0059] Sequentially, the lead clamp 310 opens and moves to the side of the stranding fixture 110, the stranding fixture 130 enters the stranding fixture 110, the wire pressing drive unit drives the upper pressure plate 410 and the lower pressure plate 420 to press the wire to be stranded, the lead clamp 310 closes and pulls one end of the wire to be stranded to the stranding clamp 210, the stranding clamp 210 clamps the wire to be stranded, and the lead clamp 310 opens and returns to the side of the stranding fixture 110.

[0060] That is, if the stranding fixture 130 is taken as the X-axis, a row of speakers to be stranded is mounted on the stranding fixture 130, and the strands to be stranded are distributed along the Y-axis. The stranding mechanism 200 is set parallel to the stranding fixture position 110, and the stranding clamp 210 points along the Y-axis toward the strands to be stranded. The wire clamping mechanism 400 is distributed along the X-axis to clamp the strands to be stranded of each speaker. The lead wire clamp 310 is distributed along the X-axis, and then moves along the Y-axis under the drive of the lead wire driver 320 to clamp the strands to be stranded on the side of the stranding fixture 130, and then pulls them onto the stranding clamp 210. The stranding drive unit 220 drives the stranding clamp 210 to rotate to complete the stranding.

[0061] Thus, the lead wire mechanism 300 allows the thinner and softer wire to be twisted to be smoothly connected by the wire clamp 210. At the same time, the clamping mechanism 400 prevents the lead wire and twisting process from damaging the solder joints, which could cause the wire to be twisted to fall off or loosen from the solder joints.

[0062] The upper pressure plate 410 is driven by the upper pressure plate cylinder 430, and the lower pressure plate 420 is driven by the lower pressure plate cylinder 440.

[0063] Furthermore, when the lead clamp 310 is closed, its upper and lower clamps are staggered, and the lead groove 311 is formed on the upper and lower clamps. Thus, after closing, neither the upper nor lower clamp is a complete closed loop; that is, the wire to be twisted has a downward adjustment gap relative to the upper clamp and an upward adjustment gap relative to the lower clamp. This reduces the risk of damaging the wire and makes it easier to adjust the clamping gap and force, facilitating the straightening of the wire.

[0064] The wire pressing mechanism 400 also includes a tooling plate 450 for pressing the stranded wire tool 130 and the speaker 700. In a preferred embodiment, the tooling plate 450 follows the upper pressure plate 410, and a tooling pressure post 451 and a speaker pressure post 452 are elastically mounted in the tooling plate 450 by springs. In this way, the stranded wire tool 130 is elastically pressed by the tooling pressure post 451, and the body of the speaker 700 is elastically pressed by the speaker pressure post 452, which compensates for the difference in pressing distance between the tooling plate 130 and the clamping distance between the upper pressure plate 410 and the lower pressure plate 420, thereby reducing the number of drive units such as cylinders, and making it easier to adjust the wire pressing force of the upper pressure plate 410 and the lower pressure plate 420.

[0065] Please refer to Figures 7-9 As shown, in a preferred embodiment, the stranded wire clamp 210 includes a pull rod seat 211, a pull rod 212, a clamping spring 213, and a four-bar clamp 214. The first end of the pull rod 212 is rotatably and axially slidably inserted into the pull rod seat 211, and the second end of the pull rod 212 extends out of the pull rod seat 211 and forms a tension boss 2121. The four-bar clamp 214 is connected to the first end of the pull rod 212, and the clamping spring 213 is sleeved on the pull rod 212 and located between the pull rod seat 211 and the pull rod seat 212. Between the four-bar clamps 214, the maximum elastic force of the clamping spring 213 is calibrated through a damage test of the wire to be stranded. The stranding drive unit 220 includes a synchronous pulley 221, a synchronous belt (not shown in the figure), a pressure wheel 222, a stranding motor 223, a release cylinder 224, and a pull plate 225. The synchronous pulley 221 is coaxially nested on the pull rod 212. The stranding motor 223 drives the synchronous pulley 221 to rotate through the synchronous belt. The pressure wheel 222 is used to press the synchronous belt to achieve tensioning of the synchronous belt. The pull plate 225 is provided with a pull groove 2251 corresponding to the boss. The release cylinder 224 drives the pull plate 225 to pull the tensioned boss 2121 to achieve release.

[0066] In this way, multiple stranded wire clamps 210 can be compactly arranged together through the above structure, and synchronous rotation drive and synchronous opening and closing of the claws can be achieved.

[0067] Furthermore, it is easy to understand that the minimum elastic force of the clamping spring 213 usually needs to meet the clamping requirements of the stranded wire 710, and the stranding is stopped by controlling the number of rotations of the stranding motor 223. However, given the thinness of the wire to be stranded in the speaker, the allowable tolerance value in its length will cause a large difference in the number of turns when transferred to the number of turns. In order to avoid the set number of turns damaging the wire when the length of the wire to be stranded is at the lower limit of the tolerance, a damage test is conducted with the wire to be stranded at the lower limit of the tolerance length, and the maximum elastic force of the clamping spring 213 is gradually adjusted until the wire to be stranded can slip or come out in the hinge claw before damage.

[0068] The present invention also includes a tooling track 100, which has a U-shaped groove, and the stranding tool 130 is accommodated in the U-shaped groove for conveying, so that the stranding tool position 110 is located in the tooling track 100.

[0069] In the stranding fixture position 110, if the stranding fixture 130 is transported via a belt drive mechanism, interference will occur between the belt drive mechanism and the wire pressing mechanism 400, etc. Therefore, the present invention employs a fixture transfer mechanism 500 to remove the stranding fixture 130, which has already completed stranding, from the stranding fixture position 110. The fixture transfer mechanism 500 includes a fixture track 100, a slide cylinder 510, a transfer cylinder 520, and a transfer block 530. The slide cylinder 510 is located below the fixture track 100, and the transfer cylinder 520 is mounted on the slide cylinder 510 and drives the transfer block 530 to rise and fall. The bottom of the fixture track 100 is provided with a clearance groove 120 for the transfer block 530 to slide, and a clamping platform 131 corresponding to the transfer block 530 is provided below the stranding fixture 130. Thus, after the stranding is completed, the transfer cylinder 520 pushes the transfer block 530 upward to abut against the clamping table 131. Then the slide cylinder 510 is activated, pushing the transfer cylinder 520 to move along the X-axis, so that the transfer block 530 pushes the clamping table 131 to move the stranding fixture 130 out of the stranding fixture position 110.

[0070] Please refer to Figure 10 and Figure 11 As shown, the present invention also includes a receiving mechanism 600, which includes a transfer unit 610 and a receiving unit 620. The transfer unit 610 is disposed above the tooling track 100 to transfer the speaker 700 on the stranded wire tooling 130. The receiving unit 620 is disposed on one side of the tooling track 100 and includes a tray 621, which holds the speaker 700 transferred by the transfer unit 610.

[0071] With the tooling track 100 as the X-axis, the transfer unit 610 includes a YZ-axis transfer device 611, a rotary driver 612, and a transfer head 613. The transfer head 613 is mounted on the YZ-axis transfer device 611 via the rotary driver 612. The receiving unit 620 also includes an X-axis transfer device 622 to drive the material tray 621 to move along the X-axis. When the YZ-axis transfer device 611 moves towards the tooling track 100 to pick up material, the rotary driver 612 rotates the transfer head 613 in the X-axis direction. When the YZ-axis transfer device 611 moves towards the material tray 621 to unload material, the rotary driver 612 rotates the transfer head 613 in the Y-axis direction. Each time the transfer head 613 unloads material, the material tray 621 is fed along the X-axis once.

[0072] This transfer method involves switching the speaker 700, originally arranged along the X-axis on the stranding fixture 130, to an X-axis arrangement during winding. In this method, the YZ-axis transferor 611 moves to the X-axis centerline of the material tray 621 each time, and the unloading time is fixed each time. In contrast, the transfer method without rotating the transfer head 613 (i.e., X-axis arrangement during winding) initially has a shorter Y-axis movement distance for the YZ-axis transferor 611. However, this shorter distance does not save process time because it requires waiting for coordination time from other processes, such as the stranding time mentioned above. As time progresses, the Y-axis movement distance of the YZ-axis transferor 611 becomes longer, requiring other stranding processes to wait for the winding to complete. This contradiction is exacerbated, especially when the number of stranding stations exceeds the number of winding stations.

[0073] Therefore, the transfer unit 610 of the present invention rotates the transfer head 613 by the rotary driver 612, and switches the material picking direction and the material unloading direction of the transfer head 613, so that the speaker 700 is arranged along the Y-axis on the material tray 621. In conjunction with the X-axis feeding of the material tray 621, the unloading efficiency can be improved.

[0074] Furthermore, the assembled speaker 700 is generally transferred to the tray 621 by magnetic attraction using the magnetism on the speaker 700. If the speaker 700 shifts, it will hinder the retrieval of materials in subsequent processes. To prevent the speaker 700 from shifting in the tray 621, a receiving groove corresponding to the speaker 700 is usually provided in the tray 621, similar to the receiving groove in the stranding fixture 130. However, in this invention, because the speaker 700 has a lead wire soldered on it, and this lead wire has been formed into a relatively long stranded wire 710 through the aforementioned stranding process, it also has a relatively soft characteristic. During the transfer process, the shape may not be uniform due to gravity or other factors. Therefore, due to the presence of the stranded wire 710, it is not easy for the speaker 700 to reliably fall into the receiving groove. Therefore, the present invention designs the surface of the material tray 621 to be flat and uses magnetic attraction to attract the speaker 700. However, this causes a new problem. Even if the magnetic attraction force of the material tray 621 is greater than that of the transfer head 613 to facilitate unloading, the magnetic force of the transfer head 613 can still easily cause the speaker 700 to shift on the material tray 621 during unloading because there is no receiving groove for positioning.

[0075] Therefore, please refer to Figure 12 and Figure 13As shown, in a preferred embodiment of the present invention, an improved transfer head 613 is employed. The transfer head 613 includes an inverted U-shaped base 6131, a magnetic strip 6132, and a magnetic strip lifting driver 6133. A pressing surface 61311 adapted to the edge contour of the speaker 700 is formed on the underside of the inverted U-shaped base 6131 for pressing against the speaker 700. The body of the magnetic strip lifting driver 6133 is disposed on the inverted U-shaped base 6131, and its driving end extends into the inverted U-shaped base 6131 to drive the magnetic strip 6132 to move up and down within the inverted U-shaped base 6131.

[0076] Thus, when the transfer head 613 picks up the material, under the action of the YZ axis transferor 611, the inverted U-shaped seat 6131 first abuts against the outline edge of the speaker 700, and then the magnetic strip lifting driver 6133 descends to attract the speaker 700; the YZ axis transferor 611 moves the transfer head 613 to the material tray 621 to unload the material. At this time, the inverted U-shaped seat 6131 abuts against the speaker 700 against the material tray 621, and then the magnetic strip lifting driver 6133 retracts the magnetic strip 6132 to release the attraction to the speaker 700. Finally, the inverted U-shaped seat 6131 rises away from the material tray 621, ready for a new round of attraction.

[0077] In addition, please refer to Figure 14 As shown, the receiving unit 620 also includes a frame 623, a tray lifting driver 624, and tray supports 625. The frame 623 includes four angle irons facing each other to correspond to the four corners of the tray 621. The Y-axis gap of the angle irons forms the receiving channel on the X-axis. The tray lifting driver 624 is located below the receiving channel. The tray supports 625 are a pair and facing each other towards the receiving channel. The tray supports 625 include a Y-axis driver 6251 and a support plate 6252 mounted on the Y-axis driver 6251. Thus, when the tray 621 is fully entered into the receiving channel, the tray lifting driver 624 drives the tray 621 to rise. After the tray 621 rises to the correct position, the tray supports 625 drive the support plate 6252 to feed along the Y-axis to support both ends of the tray 621, preventing it from falling. Then, the tray lifting driver 624 resets to clear the receiving channel, waiting for the next receiving cycle.

[0078] It is easy to understand that the various types of drivers described in this invention are not specifically limited, and those skilled in the art can select drivers such as motors, cylinders, or hydraulic cylinders according to actual needs.

[0079] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
