Description

Technical Field

[0001] The present invention relates to the technical field of wire winding machines, and particularly to a precision memory alloy wire winding device. Background Art

[0002] As a professional wire processing equipment, the precision memory alloy wire winding device is mainly used to wind memory alloy wires into specific specifications and shapes, playing an important role in high-end manufacturing fields such as aerospace, medical devices, and electronic equipment. This device integrates five core functional modules: wire feeding, guiding, winding, tension control, and driving. The wire feeding mechanism orderly releases the memory alloy wire, the guiding mechanism precisely guides the wire to the winding station, the winding mechanism winds the wire with the help of a mold or mandrel, the tension control mechanism maintains the stable tension of the wire during the winding process, and the driving system provides power support for each mechanism to ensure the efficient and precise operation of the entire winding process.

[0003] During the operation of the equipment, the wear problem at the contact part between the guiding roller and the memory alloy wire is particularly prominent. Since the memory alloy wire needs to maintain a constant tension during winding, the wire and the surface of the guiding roller are always in a state of close friction. Coupled with the relatively high hardness of the memory alloy itself, the long-term high-frequency friction will gradually damage the material structure of the guiding roller surface. This kind of wear will not only lead to a decrease in the wire guiding accuracy, resulting in dimensional deviations in the wound products and affecting product quality; but also the debris generated by the wear may adhere to the wire surface, forming scratches, further weakening the performance and reliability of the product.

[0004] In addition, the winding process of the memory alloy wire is extremely susceptible to temperature changes, which is closely related to its unique physical properties. Memory alloys have shape memory effect and superelasticity, and their mechanical properties are extremely sensitive to temperature changes. During the actual winding process, factors such as environmental temperature fluctuations and heat generated by equipment operation may change the wire temperature. Once the temperature changes, the key performance parameters such as the elastic modulus and yield strength of the memory alloy wire will also change accordingly, resulting in difficult-to-precisely control wire tension, with phenomena such as slack or breakage. At the same time, temperature changes will also affect the shape memory characteristics of the memory alloy, causing the wound products to fail to meet the design requirements, ultimately resulting in a decrease in product qualification rate and an increase in production costs.

[0005] Therefore, a precision memory alloy wire winding device is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a precision memory alloy wire winding device to solve the problems raised in the above background art.

[0007] To achieve the above object, the present invention provides the following technical solutions: A precision memory alloy wire winding device includes a precision wire winding machine, which is used to wind a memory alloy wire around a mandrel according to specific specifications and shapes. An outlet station is provided on the precision wire winding machine, and an anti-wear unit is provided on the precision wire winding machine. The anti-wear unit includes an electric telescopic rod, which is fixedly connected to the precision wire winding machine. The electric telescopic rod is divided into a fixed end and a telescopic end. A carrier plate is fixedly connected to the telescopic end of the electric telescopic rod. A fixing plate is installed on one side of the carrier plate away from the electric telescopic rod. A support rod is fixedly connected to one side of the fixing plate away from the carrier plate. One end of the support rod away from the fixing plate is rotatably connected to a rotating shaft. Both ends of the rotating shaft penetrate through the support rod. A rotating plate is fixedly connected to the rotating shaft. A side support plate is fixedly connected to one side of the carrier plate away from the electric telescopic rod. A servo motor is fixedly connected to one end of the side support plate away from the carrier plate. The servo motor is divided into a fixed end and an output shaft end. A groove sleeve is fixedly connected to the output shaft end of the servo motor.

[0008] Further, a plurality of convex blocks are fixedly connected in a ring shape on one side of the rotating plate close to the servo motor. A plurality of through holes are arranged in a ring array on the rotating plate. One fastening bolt is inserted into each of the plurality of through holes. A bracket is fixedly connected to each of the plurality of fastening bolts. One roller is rotatably connected to one end of each of the plurality of brackets away from the fastening bolts. A support telescopic tube is fixedly connected to the bottom of one side of the carrier plate close to the electric telescopic rod.

[0009] Further, a temperature control unit is provided at the outlet station. The temperature control unit includes a sleeve, which is fixedly connected to the top surface of the outlet station. A semiconductor refrigerating sheet and a temperature sensor are installed on the inner wall of the sleeve.

[0010] Further, the fixing plate is detachably connected to the carrier plate by bolts.

[0011] Further, the output shaft end of the servo motor faces the rotating plate, and the output shaft end of the servo motor and the rotating plate are coaxial.

[0012] Further, the rotation speed of the output shaft of the servo motor is set to be the same as the rotation speed of the output shaft of the rotating motor of the precision wire winding machine, and the rotation directions are the same.

[0013] Further, the plurality of convex blocks are arranged in a ring array on the rotating plate with the center position of the rotating plate as the array center. A plurality of hole grooves are provided on the groove sleeve, and the hole grooves of the groove sleeve are inserted and adapted to the convex blocks.

[0014] Further, the fastening bolts are detachably installed on the rotating plate by bolts.

[0015] Further, the sleeve is sleeved on the memory alloy wire.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Rolling friction is formed between multiple rotating rollers and the shape memory alloy wire. When the self-rotation speed of the rotating plate is synchronized with the wire winding speed of the shape memory alloy wire, the relative sliding between the shape memory alloy wire and the roller surface is significantly reduced, which significantly reduces the friction force between the two, greatly slows down the wear rate of the roller surface material, extends the service life of the guiding part, reduces debris generated by wear at the same time, avoids scratching the surface of the shape memory alloy wire, and improves product quality.

[0018] At the same time, the roller converts the contact between the shape memory alloy wire and the contact surface of the guiding part into multi-point rolling contact, greatly reducing the contact area and the friction coefficient. When the shape memory alloy wire moves, the roller can rotate synchronously with the shape memory alloy wire, converting sliding friction into rolling friction, further reducing the frictional resistance, reducing the wear of the wire surface, avoiding the influence of heat generated by friction on the performance of the shape memory alloy wire, and significantly extending the service life of the guiding part and the shape memory alloy wire at the same time.

[0019] At the same time, as a vulnerable part in direct contact with the shape memory alloy wire, the roller can be quickly disassembled and replaced with bolts after wear, avoiding the scrapping of the entire guiding part due to the loss of a single part. This "partial replacement" mode greatly shortens the equipment downtime for maintenance.

[0020] At the same time, the roller can replace the appropriate mating surface material according to the material of the shape memory alloy wire, and can be targeted to match different types of shape memory alloys (such as nickel-titanium alloys, copper-based alloys, etc.) with different hardness, surface characteristics and processing requirements, which can better reduce the wear of the roller itself and protect the surface of the shape memory alloy wire.

[0021] Through the temperature control unit, it can cool or heat quickly and accurately according to the temperature change of the shape memory alloy wire, and stabilize the temperature within a suitable range. This helps to avoid the temperature change of the shape memory alloy wire caused by environmental temperature fluctuations, heat generation during equipment operation, heat generation by friction, etc., ensures the stability of the key performance parameters of the shape memory alloy wire, reduces the fluctuations of parameters such as elastic modulus and yield strength caused by temperature, and thus improves the consistency and stability of the final wire winding forming.

[0022] Through the temperature control unit, the change in the mechanical properties of the shape memory alloy wire can be effectively reduced, so that the shape memory alloy wire can maintain a stable tensioned state during the wire winding process, reduce the risk of wire relaxation or fracture, improve the wire winding quality and production efficiency, and help ensure the accurate realization of the shape memory characteristics of the shape memory alloy wire, and improve the qualified rate of products.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiments provided by the present invention:

[0037] Embodiment 1:

[0038] Please refer to Figures 1 to 8As shown in the figure, a precision memory alloy wire winding device includes an anti-wear unit provided on a precision wire winding machine 11. It should be noted that the precision wire winding machine 11 is a device used to wind a memory alloy wire 13 around a mandrel 12 according to specific specifications and shapes, and an outgoing wire station 14 is provided on the precision wire winding machine 11.

[0039] It should be added that: Referring to Figure 2 As shown in the figure, the precision wire winding machine 11 includes a workbench, a rotating motor, and an electric push rod. The rotating motor is divided into a fixed end and an output shaft end. The fixed end of the rotating motor is installed on the workbench. The electric push rod includes a fixed end and a telescopic end. The output shaft end of the rotating motor is fixedly connected to the fixed end of the electric push rod. The telescopic end of the electric push rod is detachably installed on the mandrel 12 through bolts. Specifically, the functions of the rotating motor and the electric push rod are to drive the mandrel 12 to rotate and move on the precision wire winding machine 11.

[0040] It should be added that: Referring to Figures 2 to 4 As shown in the figure, the outgoing wire station 14 is installed on the side wall of the precision wire winding machine 11 through an electric push rod. The electric push rod is installed on the precision wire winding machine 11, and the outgoing wire station 14 is installed on the telescopic end of the electric push rod. The function of the outgoing wire station 14 is to limit the memory alloy wire 13 and guide the winding route of the memory alloy wire 13, and the winding route of the memory alloy wire 13 is changed by the telescopic movement of the electric push rod.

[0041] Combined with the above-mentioned precision wire winding machine 11, mandrel 12, and memory alloy wire 13, when the precision wire winding machine 11, mandrel 12, and memory alloy wire 13 operate jointly, the mandrel 12 is detachably installed on the telescopic shaft of the electric push rod of the precision wire winding machine 11 through bolts. The memory alloy wire 13 is guided along the winding route under the action of the outgoing wire station 14. The memory alloy wire 13 is wound around the mandrel 12. As the winding progresses, the mandrel 12 rotates and moves under the coordinated action of the rotating motor and the electric push rod of the precision wire winding machine 11, so that the memory alloy wire 13 is wound around the mandrel 12 in a multi-layer spiral shape.

[0042] It should be noted that the memory alloy wire 13 is conveyed by an external wire feeding mechanism. The external wire feeding mechanism is mainly responsible for storing the raw material of the memory alloy wire 13 and releasing the wire at a stable speed and tension.

[0043] The anti-wear unit includes an electric telescopic rod 21, which is fixedly connected to the precision wire winding machine 11. The electric telescopic rod 21 is divided into a fixed end and a telescopic end. A carrier plate 22 is fixedly connected to the telescopic end of the electric telescopic rod 21. On one side of the carrier plate 22 away from the electric telescopic rod 21, a fixing plate 23 is installed. On one side of the fixing plate 23 away from the carrier plate 22, a support rod 24 is fixedly connected. One end of the support rod 24 away from the fixing plate 23 is rotatably connected to a rotating shaft 25. Both ends of the rotating shaft 25 pass through the support rod 24. A rotating plate 26 is fixedly connected to the rotating shaft 25. On one side of the carrier plate 22 away from the electric telescopic rod 21, a side support plate 27 is fixedly connected. One end of the side support plate 27 away from the carrier plate 22 is fixedly connected to a servo motor 28. The servo motor 28 is divided into a fixed end and an output shaft end. A groove sleeve 29 is fixedly connected to the output shaft end of the servo motor 28. On one side of the rotating plate 26 close to the servo motor 28, a plurality of protrusions 210 are fixedly connected in a ring shape. A plurality of through holes 211 are arranged in a ring array on the rotating plate 26. One fastening bolt 212 is inserted into each of the plurality of through holes 211. A bracket 213 is fixedly connected to each of the plurality of fastening bolts 212. One roller 214 is rotatably connected to one end of each of the plurality of brackets 213 away from the fastening bolt 212. At the bottom of one side of the carrier plate 22 close to the electric telescopic rod 21, a support telescopic tube 215 is fixedly connected.

[0044] It should be noted that: Referring to Figure 5 , Figure 7 As shown, the fixing plate 23 is detachably connected to the carrier plate 22 by bolts, and the rotating shaft 25 is rotationally connected to the support rod 24 in a limiting manner.

[0045] It should be noted that: Referring to Figures 1 to 3 As shown, the support telescopic tube 215 is divided into a fixed shaft and a telescopic shaft. The telescopic shaft end of the support telescopic tube 215 is fixedly connected to the carrier plate 22, and the fixed shaft end of the support telescopic tube 215 is fixedly connected to the precision wire winding machine 11. The function of the support telescopic tube 215 is to provide support for the electric telescopic rod 21 and the carrier plate 22.

[0046] It should be noted that: Referring to Figure 7 , Figure 8 As shown, the output shaft end of the servo motor 28 faces the rotating plate 26. The output shaft end of the servo motor 28 and the rotating plate 26 are coaxial. The plurality of protrusions 210 are arranged in a ring array on the rotating plate 26 with the center position of the rotating plate 26 as the array center. A plurality of hole grooves are provided on the groove sleeve 29. The hole grooves of the groove sleeve 29 are inserted and adapted to the protrusions 210. When the plurality of protrusions 210 are inserted into the inside of the groove sleeve 29, at this time, the rotation of the output shaft of the servo motor 28 can drive the rotating plate 26 to rotate synchronously through the insertion relationship between the groove sleeve 29 and the protrusions 210.

[0047] It should be noted that the electric telescopic rod 21 is electrically controlled by an external remote controller. The function of the electric telescopic rod 21 is that the operator can control the telescopic end of the electric telescopic rod 21 to expand and contract, so as to ensure that the roller 214 abuts against the shape memory alloy wire 13, and ensure that the roller 214 plays a guiding role.

[0048] It should be noted that: referring to Figure 8 As shown, the fastening bolt 212 is detachably installed on the rotating plate 26 through a nut. The function is that it is convenient for the operator to replace the fastening bolt 212 according to the actual guiding route and guiding angle required by the shape memory alloy wire 13, and the hardness of the shape memory alloy wire 13. Different types of shape memory alloy wires 13, such as nickel-titanium alloys and copper-based alloys, have different hardnesses, surface characteristics and processing requirements, and replace the roller 214 with a corresponding size or corresponding material. Specifically, the arc surface part of the side wall of the roller 214 is set to be concave inward, which is convenient for the roller 214 to guide the shape memory alloy wire 13.

[0049] It should be noted that: the rotation speed of the output shaft of the servo motor 28 is set to be the same as the rotation speed of the output shaft of the rotation motor of the precision wire winding machine 11, and the rotation direction is the same. The function is to ensure that the rotation speed of the rotating plate 26 is consistent with the wire winding speed of the shape memory alloy wire 13.

[0050] It should be noted that: the detachable connection between the fixed plate 23 and the carrier plate 22 functions to facilitate the operator to replace the rotating plate 26 with a corresponding size according to the actual guiding route required by the shape memory alloy wire 13, or when multiple rollers 214 are severely worn, the operator can directly replace the multiple rollers 214 provided on the rotating plate 26 by replacing the rotating plate 26, which can reduce the time required for replacing the rollers 214 one by one.

[0051] It should be noted that: each replaced rotating plate 26 with a different size is provided with a convex block 210. It should be added that when actually disassembling the fixed plate 23 and the carrier plate 22, the bolt at the connection between the fixed plate 23 and the carrier plate 22 can be screwed out, and then the fixed plate 23, the support rod 24, the rotating shaft 25, the rotating plate 26 and other structures are horizontally taken out along the axial direction of the rotating shaft 25, so that the insertion relationship between the hole groove of the groove sleeve 29 and the convex block 210 is released. When actually installing the fixed plate 23 and the carrier plate 22, first horizontally insert the convex block 210 into the groove sleeve 29, and then tighten and fix the fixed plate 23 and the carrier plate 22 with bolts.

[0052] In the preparation stage before the operation of the anti-wear unit, that is, it is necessary to adjust the anti-wear unit to the guiding route and guiding angle required for the wire winding of the shape memory alloy wire 13, and the material of the guiding contact surface adapted to the material of the shape memory alloy wire 13. The specific operation is as follows:

[0053] The operator adjusts the telescopic length of the electric telescopic rod 21 according to the guide route so that the roller 214 is located at the required guide position. At the same time, the operator replaces the rotating plate 26 with a suitable size and replaces the roller 214 with a suitable material.

[0054] After completion, the operator starts the precision wire winding machine 11 and fixes the bottom end of the memory alloy wire 13 on the mandrel 12 by glue. As the precision wire winding machine 11 is started, the mandrel 12 is driven to rotate and move, and the memory alloy wire 13 is spirally wound on the mandrel 12 in multiple layers. At this time, the anti-wear unit is running. In the process of winding the memory alloy wire 13, the output shaft of the servo motor 28 rotates through the plug-in relationship between the slot sleeve 29 and the protrusion 210 to drive the turn plate 26 to rotate synchronously. Combined with the above-mentioned characteristics that the output shaft of the servo motor 28 and the output shaft of the rotating motor of the precision wire winding machine 11 have the same speed and the same rotation direction, the turn plate 26 drives the rotation speed of multiple rollers 214 to be the same as the winding speed of the memory alloy wire 13, and the rotation direction of the multiple rollers 214 is the same as the moving winding direction of the memory alloy wire 13, and when a single roller 214 is in contact with the memory alloy wire 13, the roller 214 is driven by the memory alloy wire 13 to rotate on the corresponding bracket 213.

[0055] In summary, during the operation of the anti-wear unit, the following beneficial effects can be achieved:

[0056] In the prior art, there is sliding friction between the guide roller and the memory alloy wire 13, while the anti-wear unit forms rolling friction between a plurality of rotating rollers 214 and the memory alloy wire 13, and when the rotation speed of the rotating plate 26 is synchronized with the winding speed of the memory alloy wire 13, the relative sliding between the surface of the memory alloy wire 13 and the roller 214 is greatly reduced, which significantly reduces the friction between the two, greatly slows down the wear rate of the surface material of the roller 214, extends the service life of the guide part, and at the same time reduces the debris generated by wear, avoids scratches on the surface of the memory alloy wire 13, and improves product quality.

[0057] At the same time, the rollers 214 transform the surface contact between the memory alloy wire 13 and the guide portion into multi-point rolling contact, significantly reducing the contact area and friction coefficient. As the memory alloy wire 13 moves, the rollers 214 rotate synchronously with it, converting sliding friction into rolling friction. This further reduces frictional resistance, minimizes surface wear, and prevents frictional heat from affecting the performance of the memory alloy wire 13. This significantly extends the service life of the guide portion and the memory alloy wire 13.

[0058] Furthermore, the roller 214, a vulnerable component that comes into direct contact with the memory alloy wire 13, can be quickly replaced by removing the bolts when worn, preventing the entire guide section from being scrapped due to the wear of a single component. This "partial replacement" model significantly reduces equipment downtime for maintenance.

[0059] Meanwhile, the fitting surface material of the roller 214 can be replaced according to the material of the shape memory alloy wire 13, and appropriate fitting surface materials can be selected to specifically match different types of shape memory alloy wires 13 with different hardness, surface characteristics and processing requirements, such as nickel-titanium alloys, copper-based alloys, etc., which can better reduce the wear of the roller 214 itself and protect the surface of the shape memory alloy wire 13.

[0060] Embodiment 2:

[0061] On the wire outlet station 14, a temperature control unit for adjusting the winding temperature of the shape memory alloy wire 13 is provided. The temperature control unit includes a sleeve 31, which is fixedly connected to the top surface of the wire outlet station 14, and the sleeve 31 is sleeved on the shape memory alloy wire 13. A semiconductor refrigeration sheet 32 and a temperature sensor 33 are installed on the inner wall of the sleeve 31.

[0062] It should be added that: the semiconductor refrigeration sheet 32 and the temperature sensor 33 are used to control the temperature inside the sleeve 31 to the appropriate winding temperature of the shape memory alloy wire 13. The temperature sensor 33 can also feedback the internal temperature of the sleeve 31 to the temperature control system in real time, and the temperature control system adjusts the internal temperature of the sleeve 31 through the semiconductor refrigeration sheet 32 to ensure the accuracy of the temperature adjustment of the semiconductor refrigeration sheet 32.

[0063] In summary: during the winding process of the shape memory alloy wire 13, the temperature of the shape memory alloy wire 13 can be adjusted so that the shape memory alloy wire 13 is adjusted to the appropriate winding temperature, and the following beneficial effects can be achieved:

[0064] Through the temperature control unit, cooling or heating can be carried out quickly and accurately according to the temperature change of the shape memory alloy wire 13, and the temperature can be stabilized within an appropriate range. This helps to avoid the temperature change of the shape memory alloy wire 13 caused by environmental temperature fluctuations, heat generation during equipment operation, frictional heat generation, etc., ensures the stability of the key performance parameters of the shape memory alloy wire 13, and reduces the fluctuations of parameters such as elastic modulus and yield strength caused by temperature, thereby improving the consistency and stability of the final winding forming.

[0065] At the same time, due to the shape memory characteristics of the shape memory alloy being sensitive to temperature, and the temperature change will cause the mechanical properties of the shape memory alloy wire 13 to change, which in turn affects the tension state of the shape memory alloy wire 13 during winding. Through the temperature control unit, the change of the mechanical properties of the shape memory alloy wire 13 can be effectively reduced, so that the shape memory alloy wire 13 can maintain a stable tension state during the winding process, reduce the risk of the shape memory alloy wire 13 being loose or broken, improve the winding quality and production efficiency, and help to ensure that the shape memory characteristics of the shape memory alloy wire 13 are accurately realized, and improve the qualified rate of products.

Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
