Description

Technical Field

[0001] This utility model relates to the field of winding equipment, specifically to a waste wire collection device for winding machines. Background Technology

[0002] As a core piece of equipment in electronic coil manufacturing, the winding machine's core function is to automatically wind conductive materials such as copper and aluminum wires onto a bobbin or magnetic core using precise mechanical control, forming a coil structure that meets electromagnetic performance requirements. A typical process flow for existing winding machines is as follows: First, the starting end of the wire is clamped and fixed using a wire end clamp. Then, the winding mechanism drives the wire to wind onto the bobbin. After winding, a pulling mechanism drives the wire end clamp to flip and stretch the wire, causing it to break under tension. Finally, the wire end clamp releases the wire, and the broken waste wire falls into a waste wire collection trough at the bottom of the equipment for collection.

[0003] However, existing winding machines have significant technical defects in the waste wire handling process. When the wire pulling mechanism performs the breaking action, the wire end clamp needs to apply a clamping force exceeding 30%-50% of the wire's tensile strength. During this process, microscopic burrs, residual lubricant, or electrostatic adsorption effects caused by severe plastic deformation on the wire surface can lead to mechanical interlocking or physical adhesion between the wire end and the wire end clamp surface. According to actual production data, in continuous operation scenarios, more than 60% of winding machines have waste wire adhesion problems, manifested as the waste wire end getting stuck in the wire end clamp jaws or wrapped around the drive shaft system, directly causing two serious consequences: First, the adhered waste wire may interfere with the positioning accuracy of subsequent winding, leading to coil turn deviation or interlayer insulation failure, increasing the product defect rate by 15%-20%; Second, to ensure the normal operation of the equipment, manual shutdown and cleaning are required every 2 hours, with each maintenance taking about 8-10 minutes, reducing the overall equipment efficiency (OEE) by more than 12%. Although some manufacturers have tried to improve this problem by adding compressed air purging modules, due to the complexity of the wire end clamp structure and the range of airflow disturbance, 20%-30% of waste wires still cannot be completely removed, which cannot meet the demand of smart manufacturing for "zero intervention" production.

[0004] Therefore, it is necessary to develop a waste wire collection device for winding machines with active anti-adhesion function to solve the problem of waste wire adhesion. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This utility model provides a waste wire collection device for winding machines, which can at least solve the technical problem of how to automatically remove the waste wire adhering to the wire end clamp after the wire is pulled.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste wire collection device for a winding machine, wherein the winding machine includes a wire pulling mechanism and a plurality of wire end clamps connected to it, the wire end clamps including a clamping part for clamping or releasing the wire end, and the wire pulling mechanism is used to drive the plurality of wire end clamps to rotate to break a plurality of wires; the waste wire collection device for the winding machine includes:

[0009] Mounting rack;

[0010] The wire scraping mechanism is mounted on the mounting frame and located below the wire end clamp. The wire scraping mechanism includes at least two scrapers arranged along the width direction of the winding machine. There is a clamp passage between two adjacent scrapers. The number of clamp passages is the same as the number of wire end clamps and their positions correspond one-to-one. The clamp passage is used for the clamping part of the corresponding wire end clamp to pass through.

[0011] The lifting mechanism is mounted on the mounting frame and is connected to the wire pulling mechanism or several wire end clamps. The lifting mechanism is used to drive the lifting movement of several wire end clamps so that several clamping parts pass through the corresponding clamp passages, thereby scraping the waste wire off the corresponding clamping parts.

[0012] A waste wire container is located below the wire scraping mechanism and is used to collect waste wire.

[0013] Furthermore, the aforementioned scraper is made of a flexible or plastic material that can be bent and rebound, and the width of the clamp passage is not greater than the width of the clamping part.

[0014] Furthermore, the aforementioned scraper is made of a hard material, and the width of the clamp passage is equal to the width of the clamping part.

[0015] Furthermore, the aforementioned scraping mechanism also includes a scraping frame, which includes connecting plates. The number of connecting plates is the same as the number of scrapers and they are arranged in a one-to-one correspondence. The scrapers are detachably mounted on the corresponding connecting plates, and the gap between two adjacent connecting plates is greater than the width of the clamping part.

[0016] Furthermore, the aforementioned scraping mechanism also includes pressure plates. The number of pressure plates is the same as that of scrapers and they are arranged in a one-to-one correspondence. The corresponding connecting plate, scraper and pressure plate are stacked in sequence from bottom to top and are fixed together by threaded components. The width of the pressure plate is not greater than the width of the connecting plate.

[0017] In a further configuration, the aforementioned lifting mechanism is located below the wire end clamp, and the wire scraper also includes a baffle plate located on one side of the lifting mechanism.

[0018] As a further feature, the aforementioned waste wire container has a discharge port on two opposite sides or one side, and a bellows cover is installed at the discharge port of the waste wire container. The bellows cover can be folded to expose the discharge port.

[0019] Furthermore, the aforementioned accordion cover is made of silicone or plastic.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the waste wire collection device for winding machines provided by this utility model has the following advantages:

[0022] After the winding machine finishes winding, the wire pulling mechanism drives several wire end clamps to flip and stretch the wire away from the winding mechanism, breaking several wires. Then, the wire end clamps release the wire ends. The broken waste wires fall into the waste wire container below. At the same time, the lifting mechanism drives several wire end clamps to perform at least one lifting and reciprocating motion, so that the clamping part passes through the corresponding clamp passage at least once. The waste wire is scraped off the corresponding clamping part by the scraper and falls into the waste wire container. Finally, the wire pulling mechanism drives several wire end clamps to flip towards the winding mechanism and return to their original position. As can be seen, the waste wire collection device for winding machines provided by this utility model, through the cooperation of a scraping mechanism and a lifting mechanism, can automatically scrape off the waste wire adhering to the wire end clamp after pulling the wire, avoiding the impact of waste wire residue on subsequent winding work; the waste wire container can catch all falling waste wire, effectively preventing the waste wire from being thrown into other devices of the winding machine due to the high-speed movement of the wire pulling mechanism, avoiding waste wire from getting tangled in other devices and causing equipment failure, ensuring the normal operation of other devices of the winding machine, making the production environment cleaner and more orderly, reducing the workload and frequency of manual waste wire cleaning, reducing manual cleaning costs, saving production costs for enterprises, and improving overall economic benefits.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] A winding machine includes a wire pulling mechanism 1 and several wire end clamps 2. Each wire end clamp 2 includes a clamping part 21 for clamping or releasing the wire end. The output end of the wire pulling mechanism 1 and the several wire end clamps 2 are fixedly connected by screws or welding. The wire pulling mechanism 1 drives the several wire end clamps 2 to rotate, thereby breaking several wires.

[0033] This utility model provides a waste wire collection device for a winding machine, which solves the problem of how to automatically remove the waste wire adhering to the wire end clamp 2 after the wire is pulled.

[0034] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a perspective view of the waste wire collection device on the winding machine in the embodiment. Figure 2 for Figure 1 Enlarged diagram of point A in the middle. Figure 3 The diagram shows the structure of the wire pulling mechanism, the wire end clamp, and the waste wire collection device of the winding machine in the embodiment. The waste wire collection device of the winding machine includes a mounting frame 3, a scraping mechanism 4, a lifting mechanism 5, and a waste wire container 6.

[0035] The wire scraping mechanism 4 is mounted on the mounting frame 3 and located below the wire end clamp 2. The wire scraping mechanism 4 includes at least two scrapers 41 arranged along the width direction of the winding machine. A clamping passage 42 is provided between two adjacent scrapers 41. The number of clamping passages 42 is the same as the number of wire end clamps 2, and their positions correspond one-to-one. The clamping passages 42 are used for the clamping part 21 of the corresponding wire end clamp 2 to pass through.

[0036] The lifting mechanism 5 is mounted on the mounting frame 3 and is connected to the wire pulling mechanism 1 or several wire end clamps 2. The lifting mechanism 5 is used to drive the lifting movement of several wire end clamps 2 so that several clamping parts 21 pass through the corresponding clamp passages 42, thereby scraping the waste wire off the corresponding clamping parts 21.

[0037] Waste wire container 6 is installed below scraper mechanism 4 and is used to collect waste wire.

[0038] After the winding machine finishes winding, the wire pulling mechanism 1 drives several wire end clamps 2 to flip and stretch the wire away from the winding mechanism, breaking several wires. Then, the wire end clamps 2 release the wire ends. The broken waste wires fall into the waste wire container 6 below. At the same time, the lifting mechanism 5 drives several wire end clamps 2 to perform at least one lifting and reciprocating motion, so that the clamping part 21 passes through the corresponding clamp passage 42 at least once, thereby scraping the waste wires off the corresponding clamping part 21 by the scraper 41. The scraped waste wires also fall into the waste wire container 6. Finally, the wire pulling mechanism 1 drives several wire end clamps 2 to flip towards the winding mechanism and return to their original positions.

[0039] As can be seen, the waste wire collection device of the winding machine in the above technical solution, through the cooperation of the scraping mechanism 4 and the lifting mechanism 5, can automatically scrape off the waste wire adhering to the wire end clamp 2 after pulling the wire, avoiding the impact of waste wire residue on subsequent winding work; the waste wire container 6 can catch all the falling waste wire, effectively preventing the waste wire from being thrown into other devices of the winding machine due to the high-speed movement of the wire pulling mechanism 1, avoiding the waste wire from getting tangled in other devices and causing equipment failure, ensuring the normal operation of other devices of the winding machine, making the production environment cleaner and more orderly, reducing the workload and frequency of manual waste wire cleaning, reducing manual cleaning costs, saving production costs for enterprises, and improving overall economic benefits.

[0040] The aforementioned lifting mechanism 5 can use existing linear drive devices such as telescopic cylinders and telescopic poles, and be installed on the mounting frame 3 by means of screwing or welding. Its output end is fixedly connected to the wire pulling mechanism 1, or rotatably connected to several wire end clamps 2.

[0041] In the first embodiment of the scraper 41, the scraper 41 is made of a flexible or plastic material that can be bent and rebound, and the width of the clamping passage 42 is not greater than the width of the clamping part 21. In this way, when the clamping part 21 passes through the clamping passage 42, the scraper 41 can better fit the surface of the clamping part 21, effectively scraping away waste thread, and the flexible and rebounding characteristics can avoid damage to the clamping part 21; while the design of the width of the clamping passage 42 can ensure that the scraper 41 and the clamping part 21 are in full contact during scraping, improving the scraping effect.

[0042] In a second embodiment of the scraper 41, the scraper 41 is made of a hard material, and the width of the clamping passage 42 is equal to the width of the clamping part 21. Thus, the scraper 41, made of hard material, can provide a stable scraping force during the scraping process, making it easier to scrape off waste thread; and the design of the width of the clamping passage 42 effectively avoids interference between the scraper 41 and the clamping part 21, thereby preventing damage to the clamping part 21.

[0043] See Figure 2 and Figure 3As shown, based on any embodiment of the scraper 41 described above, the scraping mechanism 4 further includes a scraper frame 43. The scraper frame 43 includes connecting plates 431. The number of connecting plates 431 is the same as that of the scrapers 41, and they are arranged in a one-to-one correspondence. The scraper 41 is detachably mounted on the corresponding connecting plate 431. The gap between two adjacent connecting plates 431 is greater than the width of the clamping part 21. In this way, the scraper 41 can be detachably mounted, which facilitates quick replacement when the scraper 41 is damaged or needs to be replaced with a scraper 41 of a different specification, improving the maintainability and flexibility of the equipment; while the gap design between adjacent connecting plates 431 can effectively prevent the clamping part 21 from interfering with the connecting plate 431 when passing through the clamp passage 42, ensuring that the scraping process proceeds smoothly.

[0044] See Figure 2 and Figure 3 As shown, based on the above embodiment of the connecting plate 431, the scraping mechanism 4 further includes a pressure plate 44. The number of pressure plates 44 is the same as the number of scrapers 41, and they are arranged in a one-to-one correspondence. The connecting plate 431, scraper 41, and pressure plate 44 are stacked sequentially from bottom to top and are fixed together by a threaded assembly (not shown in the figure) that passes through and screws them together. The width of the pressure plate 44 is not greater than the width of the connecting plate 431. Thus, the setting of the pressure plate 44 further enhances the connection stability between the scraper 41 and the connecting plate 431, preventing the scraper 41 from loosening or falling off during use, and enlarges the mounting and connecting surface of the scraper 41, thereby extending the service life of the scraper 41. The width design of the pressure plate 44 effectively avoids interference between the clamping part 21 and the pressure plate 44 when passing through the clamp passage 42, ensuring smooth scraping.

[0045] The aforementioned threaded assembly can use existing bolt and nut assemblies or screw double nut assemblies, etc.

[0046] See Figure 1 and Figure 3 As shown, based on the above-described embodiment of connecting plate 431, the lifting mechanism 5 is located below the wire end clamp 2. The wire scraper 43 also includes a baffle plate 432, which is located on one side of the lifting mechanism 5. Thus, the baffle plate 432 can prevent waste wire from being thrown onto the lifting mechanism 5, avoiding the waste wire from tangling around the components of the lifting mechanism 5 and affecting its normal operation, thereby extending the service life of the lifting mechanism 5 and reducing the equipment failure rate.

[0047] See Figure 1As shown, based on any of the above embodiments, the waste wire container 6 has a discharge port on two opposite sides or one side (not shown in the figure). A bellows cover 7 is slidably attached to the discharge port of the waste wire container 6. The bellows cover 7 can be folded to expose the discharge port. In this way, the bellows cover can be unfolded to close the discharge port, effectively preventing waste wire from moving out of the discharge port, and also playing a protective role, effectively preventing waste wire from being thrown onto other mechanisms; when it is necessary to clean the waste wire, the bellows cover can be folded to expose the discharge port, making it convenient for workers to remove the waste wire from the waste wire container 6 from the discharge port, improving cleaning efficiency.

[0048] In one embodiment of the accordion cover, the cover is made of silicone or plastic. Accordion covers made in this way have good flexibility and folding properties, allowing for easy folding and unfolding, are not easily damaged, and are relatively inexpensive. At the same time, the silicone or plastic material ensures good sealing, effectively preventing waste thread leakage and maintaining a clean production environment.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
