Description

Technical Field

[0001] This utility model relates to the field of machining, specifically a fuse winding machine that automatically adjusts resistance. Background Technology

[0002] In existing winding equipment, the left and right cone-shaped components that hold the metal fusible wire spool are often fixedly connected by a steel shaft. The metal fusible wire spool is fixed by passing the steel shaft through the central cavity of the metal fusible wire spool. When the fusible wire on the metal fusible wire spool is finished winding and a new metal fusible wire spool needs to be replaced, this fixed connection method often has the problem of inconvenient disassembly, resulting in low replacement efficiency and affecting the production progress.

[0003] Furthermore, existing winding equipment lacks a technical solution for real-time detection of whether the fuse resistance meets expectations, making it impossible to promptly identify winding quality defects and make corresponding adjustments, resulting in rework and resource waste in subsequent processing.

[0004] Therefore, designing a winding machine that can solve the problem of inconvenience in replacing metal wire spools in existing technologies, and that can check the winding quality and make timely adjustments to the winding quality, has become an urgent problem to be solved. Utility Model Content

One end of the spring abuts against the hollow driven roller cone, and the other end abuts against the limiting ring.

[0008] Furthermore, the resistance detection contact includes a first detection contact, a second detection contact, a third detection contact, and a fourth detection contact. The first detection contact, the second detection contact, the third detection contact, and the fourth detection contact are spaced apart on the fixed plate.

[0009] Furthermore, a first wire pressing assembly is provided between the first detection contact and the outlet nozzle. The first wire pressing assembly includes a first wire pressing wheel and a second wire pressing wheel, wherein the first wire pressing wheel and the second wire pressing wheel are symmetrically arranged on one side near the outlet nozzle, and the first wire pressing wheel can move in a direction close to or away from the second wire pressing wheel.

[0010] Furthermore, a second wire pressing assembly is provided between the first wire pressing wheel and the first detection contact. The second wire pressing assembly includes a third wire pressing wheel and a fourth wire pressing wheel. The third wire pressing wheel and the fourth wire pressing wheel are symmetrically arranged on the side close to the first detection contact, and the third wire pressing wheel can move in the direction of approaching or moving away from the fourth wire pressing wheel.

[0011] Furthermore, a first wire feeding wheel is provided between the third wire pressing wheel and the first detection contact, and the first wire feeding wheel is fixed to the fixed plate; A second feed wheel is also provided between the third detection contact and the winding spool, and the second feed wheel is fixed to the fixed plate.

[0012] Furthermore, a wire conveying wheel is also provided directly below the second wire feeding wheel, and the wire conveying wheel has an annular groove.

[0013] Furthermore, two threading plates are also spaced apart on the outside of the wire feeding bracket. The two threading plates are arranged vertically and vertically, and both threading plates are provided with threading holes. A conductor post assembly is also provided between the two wire guide plates. The conductor post assembly includes horizontal straight conductor posts arranged at intervals from top to bottom, and hook conductor posts provided between adjacent horizontal straight conductor posts.

[0014] Furthermore, a wire transmission assembly is provided between the wire threading plate and the wire feeding bracket.

[0016] In summary, the present invention has the following advantages compared with the prior art: This product utilizes an innovatively designed sliding fit structure between the bushing clamping slider and the fixed rod, combined with an adjustable hollow driven roller cone, to achieve rapid disassembly and replacement of the metal fusible wire spool. Specifically, when replacing the metal fusible wire spool, simply rotate the handle on the bushing clamping slider to loosen the clamping part from the fixed rod. This allows the bushing clamping slider to slide horizontally along the fixed rod, simultaneously moving the hollow driven roller cone away from the hollow driving roller cone, thus releasing the clamping force on the metal fusible wire spool. A new metal fusible wire spool can then be installed. The entire process is simple, significantly reducing replacement time and effectively improving production efficiency.

[0017] Meanwhile, this product, through its matching four-wire resistance tester and two sets of cooperating resistance detection contacts, constructs a precise real-time winding resistance detection system, completely solving the problem that traditional equipment cannot timely control winding quality. The resistance detection contacts are divided into two sets: the first and fourth detection contacts form one set, and the second and third detection contacts form another. Each set of contacts connects to the corresponding interface of the four-wire resistance tester. When the wound fuse is simultaneously connected to both sets of contacts, a complete detection circuit is formed. When the detected resistance value deviates from the preset range, the resistance tester feeds back the abnormal signal to the back-end control system. The back-end control system promptly adjusts the rotation speed of the roller, thereby regulating the winding tension and tightness of the fuse, achieving precise control of winding quality and significantly improving product consistency and yield.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] According to one embodiment of the present invention, such as Figures 1-6 As shown, an automatic resistance-adjusting fuse winding machine includes: A fixed frame 1 is provided with a fixed rod 2. A bushing clamping slider 3 is slidably connected to the fixed rod 2. The bushing clamping slider 3 is provided with a clamping part and a rotating handle 4 for driving the clamping part to clamp or loosen the fixed rod 2. A wire feeding bracket 5 is fixedly provided on the bushing clamping slider 3. The wire feeding tube 6 is fixed on the wire feeding bracket 5. Its opening is fixedly connected to a hollow driven roller cone 7 that can rotate around the wire feeding tube 6. A hollow active roller cone 8 is provided on its side at intervals. A metal filament spool 9 with a hollow cavity is abutted between the hollow driven roller cone 7 and the hollow active roller cone 8. The two are connected to the wire feeding tube 6 through the hollow cavity of the metal filament spool 9. A roller 10 is connected to the hollow active roller cone 8. On the other side of the roller 10 away from the hollow active roller cone 8, there is a wire outlet 11 that communicates with the hollow active roller cone 8. The roller 10 is also provided with a wire picking fork 12, which is located between the hollow active roller cone 8 and the roller 10. The wire picking fork 12 and the roller 10 are connected by a wire feeding channel. The wire outlet of the wire feeding channel is on the same side as the wire outlet 11. The roller 10 is also provided with a winding post 13, which is located between the wire outlet of the wire feeding channel and the wire outlet 11. A winding spool 14 is spaced apart from the outlet nozzle 11 and is used to receive the wound fuse. A winding reel 15 is disposed on the outside of the winding spool 14 and is used to transport the wound fuse onto the winding spool 14. A resistance detection contact is provided between the outlet nozzle 11 and the winding spool 14, and is connected to a resistance detector 23 for real-time monitoring of the resistance value of the output fuse of the outlet nozzle 11.

[0030] In this embodiment, the hollow cavity of the hollow driven roller cone 7 is connected to the outlet of the feed tube 6, and the hollow driven roller cone 7 can rotate around the feed tube 6. The hollow driven roller cone 8 is connected to the hollow driven roller cone 7 through the hollow cavity of the metal filament wire shaft 9. The outlet nozzle 11 is connected to the outlet of the hollow driven roller cone 8. The hollow driven roller cone 8 and the roller 10 drive the hollow driven roller cone 8 to rotate synchronously. The outlet nozzle 11 is used to output glass fiber wire. The left and right forks of the wire-taking fork 12 are equipped with wire-rolling wheels 42, with the wire-rolling wheel 42 on the top surface of the left fork and the right fork... The wire-rolling wheel 42 is located on its bottom surface. The wire-taking fork 12 and the roller 10 are provided with a connected wire feeding channel. There are two winding posts 13, which are symmetrically arranged on the side of the outlet of the wire feeding channel. The head of each winding post 13 is provided with a wire-rolling wheel 42. The molten wire is wound onto the wire-rolling wheel 42 of the wire-taking fork 12, enters the wire feeding channel, and is then wound onto the wire-rolling wheel 42 on the winding post 13. The rotation of the roller 10 drives the wire-rolling wheel 42 on the winding post 13 to rotate synchronously, thereby realizing the continuous feeding of the molten wire and evenly winding the molten wire onto the glass fiber wire to form a fuse.

[0031] In this embodiment, the bushing clamping slider 3 and the fixing rod 2 form an adjustable sliding fit structure, realizing the quick disassembly and replacement of the metal fusible wire spool 9. Specifically, when it is necessary to replace the metal fusible wire spool 9, simply rotate the rotating handle 4 on the bushing clamping slider 3 to drive the clamping part to loosen the fixing rod 2, which will push the bushing clamping slider 3 to slide horizontally along the fixing rod 2. At the same time, it will drive the hollow driven roller cone 7 away from the hollow driving roller cone 8, so that the clamping state between the two on the metal fusible wire spool 9 is released. Then, a new metal fusible wire spool 9 can be replaced. The whole process is simple to operate, greatly shortens the replacement time, and effectively improves production efficiency.

[0032] Furthermore, this product, through the matching four-wire resistance detector 23 and resistance detection contacts, constructs a precise real-time winding resistance detection system, completely solving the problem that traditional equipment cannot timely control the winding quality. Specifically, when the wound fuse is synchronously connected to the resistance detection contacts, a complete detection circuit is formed. When the detected resistance value deviates from the preset range, the resistance detector 23 feeds back the abnormal signal to the background control system. The background control system promptly adjusts the rotation speed of the roller 10, thereby regulating the winding tension and tightness of the fuse, thus achieving precise control of the winding quality and significantly improving product consistency and yield.

[0033] In one possible implementation, the fixing rod 2 consists of two horizontal fixing rods 2, the bushing clamping slider 3 passes through the fixing rod 2 and is slidably connected to it, and the two ends of the fixing rod 2 are provided with limit stops 16; A spring 17 is fitted on the wire feeding tube 6, and a limiting ring 18 is fitted on one end of the wire feeding tube 6 near the wire feeding bracket 5. One end of the spring 17 abuts against the hollow driven roller cone 7, and the other end abuts against the limiting ring 18.

[0034] In this embodiment, the two horizontally arranged fixed rods 2 provide more stable support for the bushing clamping slider 3 compared to a single fixed rod 2, preventing the slider from tilting or shaking when sliding along the rod or driving the wire feeding bracket 5 to work, thus ensuring the operational stability of the entire wire feeding structure. The limiting blocks 16 at both ends of the fixed rods 2 can limit the sliding range of the bushing clamping slider 3, preventing the bushing clamping slider 3 from sliding out of the fixed rods 2 when it is necessary to replace the metal filament spool 9 or adjust its position, thus avoiding damage to equipment components or operational safety hazards. Under the limiting action of the retaining ring 18, the spring 17 constantly applies an elastic thrust toward the hollow driven cone 7 towards the hollow driving cone 8, ensuring that the two are tightly abutted against both sides of the molten wire spool 9. This guarantees that when the hollow driving cone 8 rotates, it can stably drive the molten wire spool 9 and the hollow driven cone 7 to rotate synchronously through friction, preventing interruption or uneven molten wire delivery due to loose contact among the three. In addition, the top of the retaining ring 18 has a threaded hole, which is connected to a screw. By adjusting the screw's screw insertion depth, the position of the retaining ring 18 can be finely adjusted, thereby changing the compression of the spring 17. This allows for precise control of the clamping force between the hollow driven cone 7 and the hollow driving cone 8, adapting to the clamping requirements of molten wire spools 9 of different specifications, and improving the equipment's versatility and operational flexibility.

[0035] In one possible implementation, the resistance detection contact includes a first detection contact 19, a second detection contact 20, a third detection contact 21, and a fourth detection contact 22. The first detection contact 19, the second detection contact 20, the third detection contact 21, and the fourth detection contact 22 are spaced apart on the fixing plate 24. The first detection contact 19 and the second detection contact 20 are located on the side closer to the outlet 11, while the third detection contact 21 and the fourth detection contact 22 are located on the side away from the outlet 11.

[0036] In this embodiment, the first detection contact 19, the second detection contact 20, the third detection contact 21, and the fourth detection contact 22 are all made of graphene. The purpose of using graphene is that it has strong wear resistance and excellent conductivity, which can not only ensure the long-term use of the detection contacts, but also make the detected resistance value more accurate.

[0037] In this embodiment, the structure adopts a "four-wire detection method" design, which can effectively eliminate the interference of contact resistance on the detection results and improve the accuracy of resistance value monitoring. Specifically, the second detection contact 20 and the third detection contact 21 are "current input terminals", and the first detection contact 19 and the fourth detection contact 22 are "voltage acquisition terminals": when the wound fuse is output from the outlet 11, it will be smoothly connected to the four detection contacts in sequence. At this time, the resistance detector 23 applies a constant detection current to the fuse through the second and third detection contacts, and at the same time acquires the actual voltage across the fuse through the first and fourth detection contacts, and then calculates the true resistance value of the fuse according to Ohm's law. Four contacts are spaced apart on the fixed plate 24, which not only ensures stable contact between the fuse and the contacts, avoiding problems such as easy detachment and poor contact in single-point contact, but also eliminates the influence of contact resistance generated at the contact point between the contacts and the fuse on the test results through the "current-voltage separation acquisition" method, making the monitoring data more consistent with the actual performance of the fuse. When the detected resistance value exceeds the preset range, the resistance detector 23 can immediately feed back the abnormal signal to the background control system. The background control system can then adjust the rotation speed of the roller 10 in a timely manner, thereby adjusting the winding tension and winding tightness of the fuse. At the same time, to ensure high fault tolerance, the fixed frame 1 is also equipped with an operation control panel 40 connected to the background control system. Operators can also adjust parameters such as the winding speed of the roller 10 through the operation control panel 40 to avoid the generation of batches of unqualified products.

[0038] In one possible implementation, a first wire pressing assembly is further provided between the first detection contact 19 and the outlet 11. The first wire pressing assembly includes a first wire pressing wheel 25 and a second wire pressing wheel 26. The first wire pressing wheel 25 and the second wire pressing wheel 26 are symmetrically arranged on one side near the outlet 11, and the first wire pressing wheel 25 can move in a direction close to or away from the second wire pressing wheel 26.

[0039] In this embodiment, the core function of the first wire clamping assembly is to "preliminarily position and clamp" the fuse just output from the outlet 11, preventing the fuse from loosening, shifting, or experiencing unstable tension during subsequent transport. The specific operation is as follows: the glass fiber wire is output from the wire feeding channel of the outlet 11, and after the fused wire is wound onto the glass fiber wire to form a fuse, it directly enters the gap between the first clamping wheel 25 and the second clamping wheel 26. Then, through the rotation of the first clamping wheel 25 and the second clamping wheel 26, the glass fiber wire is driven to the subsequent process flow. When the wound fuses are of different specifications, the operator can manually adjust the size of the gap between the first clamping wheel 25 and the second clamping wheel 26 until they work together to stably clamp the fuse. This manual operation method ensures stable restriction of the fuse's position, preventing lateral shifting during transport, and also prevents damage to the fuse's surface structure or alteration of its physical properties due to excessive pressure.

[0040] In one possible implementation, a second wire pressing assembly is further provided between the first wire pressing roller 25 and the first detection contact 19. The second wire pressing assembly includes a third wire pressing roller 27 and a fourth wire pressing roller 28, wherein the third wire pressing roller 27 and the fourth wire pressing roller 28 are symmetrically arranged on one side close to the first detection contact 19, and the third wire pressing roller 27 can move in a direction close to or away from the fourth wire pressing roller 28.

[0041] In this embodiment, the second wire clamping assembly performs a "secondary precision calibration" of the first wire clamping assembly. Its core purpose is to ensure that the initially clamped fuse can connect to the resistance detection contacts in an absolutely stable posture, preventing poor contact due to slight fuse misalignment and ensuring accurate resistance monitoring. Specifically, the fuse, initially positioned by the first wire clamping assembly, directly enters the gap between the third and fourth wire clamping wheels 27 and 28. The rotation of these wheels drives the glass fiber wire to subsequent processes. When the wound fuses are of different specifications, the operator can manually adjust the gap between the third and fourth wire clamping wheels 27 and 28 until they work together to clamp the fuse securely for a second time.

[0042] In one possible implementation, a first wire feeding wheel 29 is also provided between the third wire pressing wheel 27 and the first detection contact 19, and the first wire feeding wheel 29 is fixed on the fixing plate 24; A second feed wheel 30 is also provided between the third detection contact 21 and the winding spool 14, and the second feed wheel 30 is fixed on the fixing plate 24.

[0043] In this embodiment, the specific process is as follows: the fuse, after secondary calibration by the second wire pressing assembly, will be wound around to the first wire feeding wheel 29. The first wire feeding wheel 29 consists of two wire feeding wheels arranged coaxially. The fuse will first be wound around to the rear wheel of the first wire feeding wheel 29, and then contact the second detection contact 20 and the third detection contact 21 in sequence. Then it will be wound around to the second wire feeding wheel 30. The second wire feeding wheel 30 consists of two wire feeding wheels arranged coaxially. The fuse will first be wound around to the rear wheel of the second wire feeding wheel 30, and then conveyed by the wire conveying wheel 31 and wound around to the front wheel of the second wire feeding wheel 30. Then it will contact the fourth detection contact 22 and the first detection contact 19 in sequence. After being wound around to the front wheel of the first wire feeding wheel 29, it will finally be conveyed to the subsequent process for winding on the spool 14 for take-up operation. In this process, the double wire feeding wheel structure arranged coaxially further improves the stability of fuse delivery and the accuracy of detection contact through "bidirectional clamping guidance".

[0044] In one possible implementation, a wire conveying wheel 31 is also provided directly below the second wire feeding wheel 30, and the wire conveying wheel 31 has an annular groove.

[0045] In this embodiment, after passing the second detection contact 20 and the third detection contact 21, the fuse first winds around to the rear side of the second feed wheel 30, then embeds itself in the annular groove of the feed wheel 31, and is then guided by the groove to the first detection contact 19 and the fourth detection contact 22. The annular groove of the feed wheel 31 is precisely matched with the diameter of the fuse, which can strictly limit its lateral deviation, and its installation position is precisely calibrated to form a fixed spatial layout with the second feed wheel 30 and the first feed wheel 29, so that the path of the fuse between the second and third detection contacts (current input terminals) and the first and fourth detection contacts (voltage acquisition terminals) is firmly locked.

[0046] With this design, the fuse length between the two detection contacts can be stably maintained at 1 meter, providing a constant length reference for accurate resistance measurement, ensuring the accuracy of current and voltage signal acquisition during the detection process, and avoiding measurement errors caused by line length fluctuations.

[0047] In one possible implementation, two threading plates 32 are also provided at intervals on the outer side of the wire feeding bracket 5. The two threading plates 32 are arranged vertically at intervals, and both threading plates 32 are provided with threading holes. A guide post assembly is also provided between the two wire guide plates 32, wherein the guide post assembly includes horizontal straight guide posts 33 arranged at intervals from top to bottom, and hook guide posts 34 provided between adjacent horizontal straight guide posts 33; The threading plate 32, the horizontal straight guide post 33, and the hook guide post 34 are all fitted with silicone sleeves.

[0048] In this embodiment, the specific operation process is as follows: The glass fiber thread output by the external threading device first passes through the threading hole of the lower threading plate 32. The threading hole serves as a preliminary positioning function to prevent excessive deviation in the initial conveying direction of the glass fiber thread. Subsequently, the glass fiber thread enters the guide post assembly between the two threading plates: it first slides along the silicone sleeve surface of the horizontal straight guide post 33, and then changes its conveying direction through the silicone sleeve of the hook guide post 34. After being guided by multiple sets of horizontal straight guide posts and hook guide posts, the glass fiber thread finally passes through the threading hole of the upper threading plate 32 and accurately enters the delivery tube 6 on the delivery bracket 5. The silicone sleeves on all components can, on the one hand, isolate the glass fiber thread from direct contact with metal components to prevent metal burrs from scratching the glass fiber thread; on the other hand, the elasticity of the silicone sleeves can buffer the slight vibrations during the conveying of the glass fiber thread, reduce noise, and at the same time prevent the glass fiber thread from attracting impurities due to static electricity caused by friction, ensuring its conveying stability and cleanliness.

[0049] In one possible implementation, a wire transmission assembly is further provided between the wire threading plate 32 and the wire feeding bracket 5. The wire transmission assembly includes a wire transmission wheel 35, a wire guide wheel 36, a fifth wire pressing wheel 37, and a sixth wire pressing wheel 38. The wire transmission wheel 35 is located on the side closer to the wire threading plate 32. The fifth wire pressing wheel 37 and the sixth wire pressing wheel 38 are symmetrically arranged vertically on the side closer to the wire feeding bracket 5. The fifth wire pressing wheel 37 can move in a direction closer to or away from the sixth wire pressing wheel 38. The wire guide wheel 36 is located between the wire transmission wheel 35 and the sixth wire pressing wheel 38. Both the wire conveying wheel 35 and the wire guiding wheel 36 have annular grooves.

[0050] In this embodiment, the fiber conveying assembly is a stabilizing and adjusting link before the glass fiber wire enters the feeding tube 6. Its core function is to ensure that the glass fiber wire enters the feeding tube 6 with a constant tension through the dual action of "guiding + clamping", so as to avoid the glass fiber wire being stretched or piled up due to tension fluctuations, which would affect the subsequent winding effect with the fuse.

[0051] The specific operating process is as follows: The fiberglass thread passing through the upper threading plate 32 first embeds into the annular groove of the thread-passing wheel 35. The annular groove matches the diameter of the fiberglass thread, initially limiting its lateral deviation and guiding it to the thread-passing wheel 36. Subsequently, the fiberglass thread enters the annular groove of the thread-passing wheel 36, further correcting the conveying angle so that the fiberglass thread is precisely aligned with the gap between the fifth and sixth pressure wheels. Then, through the rotation of the fifth pressure wheel 37 and the sixth pressure wheel 38, the fiberglass thread is driven to the subsequent process flow. When the fuses after winding are of different specifications, the operator can manually adjust the gap between the fifth pressure wheel 37 and the sixth pressure wheel 38 until the two work together to clamp the fuses smoothly. This manual operation method ensures that the fiberglass thread enters the feed tube 6 with stable tension without damaging the fiberglass thread due to excessive pressure. The rotation of the wire feeding wheel 35 and the wire guiding wheel 36 can reduce the conveying resistance of the glass fiber wire, ensuring that it enters the wire feeding tube 6 continuously and smoothly, and providing a stable carrier guarantee for the subsequent glass fiber wire to be output sequentially along the hollow driven roller 7, the hollow active roller 8 and the wire outlet 11, and to be wound with the fuse to form a fuse.

[0052] In one possible implementation, the winding reel 15 is rotatably mounted on a slider 39, the slider 39 being slidably connected to a horizontal guide rod, and the horizontal guide rod being arranged parallel to the winding spool 14. The slider 39 is equipped with a drive cylinder.

[0053] In this embodiment, the specific operation process is as follows: After the winding post 13 evenly winds the fuse wire onto the glass fiber line to form a fuse, the fuse reaches the winding reel 15 through the resistance detection and conveying process. At this time, a transmission belt 41 is provided on the outside of the winding spool 14. The transmission belt 41 is connected to an external drive device. The external drive device drives the winding spool 14 to rotate through the transmission belt 41, which in turn drives the winding reel 15 to rotate synchronously to guide the fuse to the winding spool 14. At the same time, the drive cylinder drives the slider 39 to reciprocate linearly along the horizontal guide rod. Since the horizontal guide rod is parallel to the winding spool 14, the movement direction of the slider 39 is completely consistent with the axis of the winding spool 14. This can drive the winding reel 15 to "evenly distribute" the fuse to various areas of the winding spool 14, avoiding the problems of "local accumulation" or "excessive gaps" and improving the quality of finished product storage.
