Description

Technical Field

[0001] This utility model relates to the field of high-speed winding machine technology, and in particular to a wire breakage detection device for high-speed winding machines. Background Technology

[0002] A high-speed winding machine is an automated device used to quickly and accurately wind conductors onto various coil frames or magnetic cores. It is widely used in the manufacturing of electronic components such as motors, transformers, inductors, and instrument transformers, as well as micro-motors. Through a precise mechanical structure and control system, it achieves high-speed conductor feeding, precise wire arrangement, and tight winding, greatly improving production efficiency and product quality. A high-speed winding machine typically consists of a wire feeding device, a winding head, a wire arrangement mechanism, a tension control system, a rotating spindle, a counter, and a control system. The wire feeding device provides and controls the conductor tension, the winding head performs the winding action according to a preset program, the wire arrangement mechanism ensures the conductor is evenly arranged on the frame, the tension control system ensures constant conductor tension, the rotating spindle drives the frame or magnetic core to rotate, the counter records the number of turns wound, and the control system coordinates the work of each part to achieve automated operation. Compared with traditional manual winding, high-speed winding machines have advantages such as high speed, high precision, good consistency, and a high degree of automation, meeting the needs of large-scale, high-precision production. They are key equipment in the modern electronic component and micro-motor manufacturing industries.

[0003] A significant technical problem with existing high-speed winding machines in practical applications is the high risk of wire breakage during the winding process due to their high operating speed. However, traditional high-speed winding machines generally lack effective wire breakage detection devices. This means that when a wire breakage occurs, the machine cannot detect it in time and stop operating, resulting in wasted time and energy. This not only reduces production efficiency and increases energy consumption but may also cause unnecessary wear and tear on the equipment itself due to continuous idling, potentially leading to more serious equipment failures. Utility Model Content

[0004] One objective of this invention is to provide a wire breakage detection device for a high-speed winding machine. This invention addresses the problem mentioned above, where traditional high-speed winding machines generally lack effective wire breakage detection devices. This results in the equipment being unable to detect and stop operation in time when a wire breakage occurs, leading to idle waste of the equipment. This not only reduces production efficiency and increases energy consumption, but may also cause unnecessary wear and tear on the equipment itself due to continuous idle operation, and may even lead to more serious equipment failures.

[0005] A high-speed winding machine anti-breakage detection device according to an embodiment of the present invention includes a winding machine body, a manual winding mechanism, and a breakage detection mechanism. The winding machine body includes a drive housing, a control housing, and a winding shaft. The winding shaft is rotatably connected between the drive housing and the control housing. The breakage detection mechanism includes a limit wheel, an electric push rod, and a fixing block. The fixing block is fixedly connected to the side surface of the fixed end of the electric push rod. A second spring is provided between one side surface of the fixing block and the outer surface of the drive housing. The limit wheel is rotatably connected to the telescopic end of the electric push rod through a connecting structure. A push switch is fixedly installed on the upper side of one side of the drive housing through a fixing plate. An indicator light is installed on the upper surface of the drive housing.

[0006] Preferably, a control panel is mounted on the upper surface of the drive housing, a drive motor is installed inside the drive housing, and the winding shaft is connected to the output end of the drive motor.

[0007] Preferably, the side surface of the limiting wheel is provided with a limiting groove for limiting the line, and the electric push rod is slidably connected to the upper part of one side of the drive housing.

[0008] Preferably, the indicator light is electrically connected to an external power supply via a push-button switch.

[0009] Preferably, the manual winding mechanism includes a driving gear and a driven gear, with the driven gear fixedly connected to one end of the winding shaft.

[0010] Preferably, a telescopic rod is movably connected to the upper part of one side of the control box, and a handwheel is fixedly connected to the outer end of the telescopic rod.

[0011] Preferably, a drive gear is fixedly connected to the telescopic end side surface of the telescopic rod.

[0012] Preferably, a first spring is installed on one side of the drive gear and the outside of the control box, and the drive gear and the driven gear mesh with each other when the drive gear is pressed inward.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a broken wire detection mechanism. During winding, the wire passes through a limiting groove on the surface of the limiting wheel, applying a force towards the electric push rod. This causes the limiting wheel and the electric push rod to be squeezed outwards, compressing the second spring. At this time, the fixing block moves away from the push switch, and the push switch is not triggered, so the indicator light is off. When a broken wire occurs, the limiting wheel and the electric push rod are reset by the second spring after the wire is no longer compressed. This causes the fixing block to squeeze towards the push switch, triggering it and illuminating the indicator light. This indicates that a broken wire has occurred on the high-speed winding machine, and the high-speed winding machine is braked. This avoids problems such as idling waste, reduced efficiency, increased energy consumption, and equipment wear, thus improving production efficiency and safety.

[0015] This invention utilizes a manual winding mechanism. During normal use, the winding shaft is automatically wound at high speed by a drive motor inside the drive housing. When fine-tuning or manual adjustment of the winding shaft is required, the drive motor inside the drive housing is turned off. Then, the handwheel is pushed inward, compressing both the telescopic rod and the first spring. Simultaneously, the inward compression of the telescopic rod engages the driving and driven gears. Rotating the handwheel then drives the driving gear, which in turn drives the driven gear and the winding roller to rotate. After adjustment, releasing the handwheel causes the first spring's restoring force to eject the handwheel and driving gear outward, dislocating them. This allows the drive motor inside the drive housing to continue driving the winding shaft at high speed for automatic winding. This flexible approach addresses different winding needs, improving the applicability and ease of operation of the equipment. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-4 A high-speed winding machine anti-breakage detection device includes a winding machine body 1, a manual winding mechanism 2, and a breakage detection mechanism 3. The winding machine body 1 includes a drive housing 11, a control housing 14, and a winding shaft 13. The winding shaft 13 is rotatably connected between the drive housing 11 and the control housing 14. The breakage detection mechanism 3 includes a limit wheel 36, an electric push rod 32, and a fixing block 33. The fixing block 33 is fixedly connected to the side surface of the fixed end of the electric push rod 32. A second spring 34 is provided between one side surface of the fixing block 33 and the outer surface of the drive housing 11. The limit wheel 36 is rotatably connected to the telescopic end of the electric push rod 32 through a connecting structure 35. A push switch 39 is fixedly installed on the upper side of one side of the drive housing 11 through a fixing plate 38. An indicator light 31 is installed on the upper surface of the drive housing 11. Through the set breakage detection mechanism 3, when the winding shaft 13 passes through the control housing 14, the breakage detection mechanism 3 detects the breakage of the winding shaft. During the winding process, the wire passes through the limiting groove 37 on the surface of the limiting wheel 36, and a force is applied to the limiting wheel 36 in the direction of the electric push rod 32, causing the limiting wheel 36 and the electric push rod 32 to be squeezed outward. The second spring 34 is compressed, and at this time the fixing block 33 moves away from the press switch 39, the press switch 39 is not triggered, and the indicator light 31 is off. When a wire break occurs, after the wire is no longer squeezed, the limiting wheel 36 and the electric push rod 32 are subjected to a reset force by the second spring 34, thereby driving the fixing block 33 to squeeze in the direction of the press switch 39. The pressing switch 39 is triggered by the fixing block 33, and the indicator light 31 lights up, indicating that a wire break has occurred in the high-speed winding machine. At the same time, the high-speed winding machine is braked, avoiding problems such as idling waste, reduced efficiency, increased energy consumption and equipment wear, and improving production efficiency and safety.

[0024] Example 1: A control panel 12 is installed on the upper surface of the drive housing 11. A drive motor is installed inside the drive housing 11. The winding shaft 13 is connected to the output end of the drive motor. A limiting groove 37 for limiting the wire is opened on the side surface of the limiting wheel 36. An electric push rod 32 is slidably connected to the upper side of the drive housing 11. An indicator light 31 is electrically connected to an external power supply through a push switch 39.

[0025] Example 2: The manual winding mechanism 2 includes a driving gear 23 and a driven gear 21. The driven gear 21 is fixedly connected to one end of the winding shaft 13. A telescopic rod 22 is movably connected to the upper side of one side of the control housing 14. A handwheel 25 is fixedly connected to the outer end of the telescopic rod 22. The driving gear 23 is fixedly connected to the telescopic end side surface of the telescopic rod 22. A first spring 24 is installed on one side of the driving gear 23 and the outer side of the control housing 14. When the driving gear 23 is pressed inward, the driving gear 23 and the driven gear 21 mesh with each other. Through the manual winding mechanism 2, the winding shaft 13 is driven to rotate at high speed by the drive motor inside the drive housing 11 to achieve automatic winding during normal use. When fine adjustment or manual adjustment of the winding shaft 13 is required, the mechanism is closed. The drive motor inside the drive housing 11 is then pushed inward via the handwheel 25, compressing both the telescopic rod 22 and the first spring 24. Simultaneously, the inward compression of the telescopic rod 22 engages the drive gear 23 and the driven gear 21. Rotating the handwheel 25 then drives the drive gear 23, which in turn drives the driven gear 21 and the winding roller to rotate. After adjustment, releasing the handwheel 25 causes the return force of the first spring 24 to eject the handwheel 25 and the drive gear 23 outward, dislocating them. This allows the drive motor inside the drive housing 11 to continue driving the winding shaft 13 to rotate at high speed, achieving automatic winding. This flexibly addresses different winding needs, improving the applicability and ease of operation of the equipment.

[0026] In operation, the drive motor inside the drive housing 11 drives the winding shaft 13 to rotate at high speed, achieving automatic winding. At this time, the wire passes through the limiting groove 37 on the surface of the limiting wheel 36 in the wire breakage detection mechanism 3, and a force is applied to the limiting wheel 36 in the direction of the electric push rod 32, causing the limiting wheel 36 and the electric push rod 32 to be squeezed outwards, compressing the second spring 34. The fixing block 33 moves away from the push switch 39, and the indicator light 31 goes out. If a wire break occurs and the squeezing force is lost, the limiting wheel 36 and the electric push rod 32 reset under the action of the second spring 34, causing the fixing block 33 to squeeze the push switch 39, the indicator light 31 illuminates, and the equipment is braked, avoiding idling waste, reduced efficiency, increased energy consumption, and equipment wear, thus improving production efficiency and safety. When fine-tuning or manual adjustment of the winding shaft 13 is required, the drive motor is turned off, and the manual winding mechanism 2 is operated. The handwheel 25 is pushed inwards, compressing the telescopic rod 22 and the first spring 24, causing the driving gear 23 to mesh with the driven gear 21. Turning handwheel 25 causes the drive gear 23 to rotate, driving the driven gear 21 and winding shaft 13 to rotate, thus achieving manual winding. After adjustment, releasing handwheel 25 causes the return force of the first spring 24 to pop out handwheel 25 and drive gear 23, dislocating the drive and driven gears 21. The drive motor inside the drive housing 11 can then drive the winding shaft 13 to rotate at high speed, achieving automatic winding. This design flexibly addresses different winding needs, improving the applicability and ease of operation of the equipment. The entire device, through automatic and manual modes combined with a wire breakage detection function, achieves efficient, safe, and flexible winding operations.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
