Description

Technical Field

[0001] This invention relates to the technical field of wire processing, and more particularly to a device for bending the lead wire of a ring coil. Background Technology

[0002] When manufacturing toroidal coils, high-quality copper is often used because of its excellent ductility and flexibility, allowing it to be made into coils of different shapes. A very thin layer of insulating varnish is coated on the outer ring of the copper coil to form enameled wire, preventing short circuits between coil turns. To facilitate assembly, the lead wires of the copper toroidal coil need to be bent into specific shapes to fit into the mounting housing, facilitating subsequent assembly operations. Existing technologies use wire bending equipment to bend the lead wires into specific shapes. For example, Chinese invention patent CN120038249A discloses a small wire forming machine, which includes a frame, a straightening mechanism, a wire feeding mechanism, and a bending mechanism arranged sequentially on the frame along the wire forming direction. The wire feeding mechanism transports the wire to the bending mechanism, where the bending mechanism bends the wire into shape.

[0003] The above solution involves bending the copper wire into a specific shape using a bending mechanism. Since the wire surface is coated with an insulating varnish, the insulation of the lead wire is usually checked manually after bending. When damage to the insulating varnish is detected, the bending mechanism is adjusted. This results in untimely adjustments to the bending mechanism, leading to an increase in the amount of scrapped lead wires after bending and thus increasing production costs. Summary of the Invention

During the bending process of the wire by the bending shaft, a detection mechanism is used to detect and locate damage to the bent wire. Based on the damage point, the operating state of the bending shaft is temperature-controlled, specifically addressing the problem of high-risk damage points, significantly reducing the insulation varnish damage rate, and improving the product qualification rate. The specific solution is as follows: A toroidal coil lead bending device, comprising: The machine body is provided with a guide plate, the guide plate has a wire groove, the outer ring of the guide plate is fitted with a bending plate, the bending plate is vertically mounted with a bending shaft for bending the wire to be formed, and the bending shaft is equipped with a temperature control component for regulating the temperature of the bending shaft.

[0009] Furthermore, the end of the screw is mounted to the machine body via a mounting plate, and the distance sensor is mounted on the mounting plate and is correspondingly set with the toggle block.

[0010] Furthermore, a telescopic motor is installed on the machine body, and a connecting plate is provided at the output end of the telescopic motor.

The tops of the temperature control cavity and the temperature conduction cavity are connected. An inner tube is connected to the outside of the temperature control cavity.

[0012] Furthermore, the temperature-conducting cavity is provided with multiple unidirectional valves, which are fixedly installed in the temperature-conducting cavity by support rods. A micro pump is installed in the inner tube. The unidirectional valves are used to restrict the temperature-controlled liquid from flowing unidirectionally from top to bottom.

[0013] Furthermore, an electric heating rod and a hydraulic sensor are installed in the temperature control cavity, and a heat transfer block is arranged between adjacent unidirectional valves.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Example 1, please refer to... Figures 1-6 As shown, this invention provides a ring coil lead wire bending device, including a body 1, a cutting mechanism 5, a detection mechanism, and a bending intelligent controller 8. The body 1 is equipped with a guide plate 2, which has a wire groove. A bending plate 3 is fitted around the outer ring of the guide plate 2, and a bending shaft 4 is vertically mounted on the bending plate 3 for bending the wire to be formed. The wire to be formed is conveyed to the guide plate 2 by a wire feeding mechanism and moves along the wire groove to the bending shaft 4. By controlling the vertical movement and circumferential rotation of the bending plate 3, the bending shaft 4 can be driven to move to both sides of the wire, thereby controlling the wire to bend to both sides. With the continuous output of the wire, the copper wire can be bent into a preset shape, ultimately producing a lead wire of the target specification. Furthermore, a temperature control component is installed on the bending shaft 4 to regulate the temperature of the bending shaft 4, thereby controlling the temperature of its contact surface with the wire.

[0026] The cutting mechanism 5 is installed at the output end of the guide plate 2 and is used to cut the forming wire to form the forming part 9. By continuously cutting the forming wire through the cutting mechanism 5, the forming part 9 can be continuously produced in batches, which effectively improves production efficiency. It should be noted that the cutting operation is carried out by the cutting knife after the wire is bent and formed. This is a conventional prior art in the field, and its technical principle is common knowledge. Therefore, this application will not elaborate on the specific structure and working principle of the cutting mechanism 5.

[0027] Please see Figures 1-3 The detection mechanism includes a conductive block 22 that matches the cut surface of the molded part 9, a measuring brush head 7 that moves along the molded part 9, and a distance sensor for detecting the displacement of the measuring brush head 7. A conductive brush is installed at the end of the measuring brush head 7, and the conductive block 22 is equipped with detection contacts corresponding to the cross-section of the molded part 9. The molded part 9, after being cut by the cutting mechanism 5, falls into the detection mechanism and is positioned by the limiting block and limiting groove on the detection mechanism. Regarding the installation position and structure of the limiting block and limiting groove, those skilled in the art can design them according to the specific shape and movement trajectory of the molded part 9 in actual production to meet the adaptation requirements of different production scenarios.

[0028] During testing, the cut surface of the molded part 9 is connected to the detection contact of the conductive block 22, controlling the measuring brush head 7 to move along the outer ring trajectory of the molded part 9, so that the conductive brush slides along the outer ring of the molded part 9; by detecting the energization state of the detection contact and the conductive brush, the damage to the external insulating varnish of the molded part 9 can be identified; at the same time, by using a distance sensor to detect the moving position of the measuring brush head 7, the damage point of the insulating varnish can be accurately located, providing a basis for the subsequent parameter adjustment of the bending mechanism.

[0029] Multi-component collaboration enables the detection and precise location of insulation varnish damage, effectively intercepting defective products and preventing them from entering subsequent stages, thus reducing rework costs. Damage point location provides accurate information for adjusting bending parameters, helping to reduce the damage rate from the source.

[0030] It is worth mentioning that you should refer to Figure 6 The bending intelligent controller 8 is installed on the body 1. The bending intelligent controller 8 is equipped with a bending control system, which includes a leakage detection module, a bending control module, a bending regulation module, and an alarm module. The bending control module is connected to the leakage detection module, the bending regulation module, and the alarm module. The leakage detection module is connected to a continuity detector and a distance sensor. The continuity detector is connected to a conductive brush and a detection contact. The bending regulation module is connected to the temperature control component.

[0031] In the wire bending operation, the bending control module controls the bending disc 3 to perform circumferential and vertical movements, driving the bending shaft 4 to complete the bending and forming of the wire. After forming, the formed part 9 is cut by the cutting mechanism 5 and then transported to the detection mechanism. At this time, the current measuring brush head 7 moves along the outer ring of the formed part 9 to detect the damage to the insulating varnish of the formed part 9. When the insulating varnish is detected to be damaged, the current measuring brush head 7 moves to the damaged position, and the continuity detector detects that the conductive brush and the detection contact form a conductive circuit. The leakage detection module then determines that the formed part 9 is damaged. The distance sensor simultaneously detects the position of the current measuring brush head 7. The system determines the specific location D of the breakage point on the molded part 9 and issues an audible and visual warning via the alarm module, indicating that the molded part 9 is a defective product. Simultaneously, the bending control module initiates its control operation. Specifically, during the bending process of the next wire through the bending shaft 4, before the bending shaft 4 reaches the corresponding location D on the wire, the bending control module activates the temperature control component on the bending shaft 4, raising its temperature to a preset temperature T. This temperature raises the temperature of the insulating varnish above its glass transition temperature (Tg), improving its flexibility and reducing the probability of breakage during bending. In summary, this device can automatically detect the molded part 9 and adjust the wire bending parameters in real time based on the detection results, effectively reducing the product breakage rate.

[0032] The fully automated design reduces human intervention, minimizes product defects caused by human error, and improves production stability; the audible and visual warning function can quickly identify defective products, avoid the risk of mixing materials, and ensure product quality consistency; the adaptive temperature control based on the damage point can specifically solve the problem of high damage risk points, significantly reduce the insulation varnish damage rate, improve the product qualification rate, and reduce raw material waste.

[0033] For some industries, such as aerospace, automotive electronics (especially EV drive motors), medical equipment, and high-end servo motors, the reliability and consistency of lead wires are required to be high. Active temperature control is used to reduce the breakage rate during bending and forming, thereby ensuring the operational reliability of the end products.

[0034] In addition, the test brush head 7 is provided with a detection line 17 that is electrically connected to the conductive brush. The other end of the detection line 17 is connected to the continuity detector signal. Test brush heads 7 are provided on both sides of the molded part 9. The conductive brush has the characteristics of being long and flexible, which can completely cover the outer ring of the molded part 9 and avoid damaging the insulating varnish, thus ensuring comprehensive testing of the insulating varnish of the outer ring of the molded part 9.

[0035] In this embodiment, please refer to Figures 3-5The machine body 1 has a recessed detection chamber 6 corresponding to the detection mechanism. Below the detection chamber 6 is a track plate 13 with the same structure as the molded part 9. The outer wall of the track plate 13 abuts against a tracking block 15. The tracking block 15 is connected to the electrical testing brush head 7 through a linkage frame 16. By setting a track plate 13 with the same structure as the molded part 9, when the tracking block 15 moves along the outer ring of the track plate 13, the linkage frame 16 can synchronously drive the electrical testing brush head 7 to move, so that the electrical testing brush head 7 moves along the outer ring contour of the molded part 9, effectively reducing the pressure of the electrical testing brush head 7 on the outer ring of the molded part 9 and avoiding damage to the insulating varnish. In addition, the track plate 13 of the corresponding shape can be replaced according to the different structures of the molded part 9 to be processed, so that the device is suitable for various bending shape lead wire structures. It should be added that the tracking block 15 is engaged on both sides of the track plate 13, and the tracking block 15 and the track plate 13 are rotatably connected to rollers at the corresponding positions on the sides, which can reduce the frictional resistance between the tracking block 15 and the track plate 13 and ensure that the tracking block 15 moves smoothly along the outer ring of the track plate 13.

[0036] In addition, the bottom of the testing chamber 6 is set at an angle. After the test, the molded parts 9 slide down the inclined surface to the material box at the bottom. Multiple material boxes are used to distinguish between qualified and unqualified products, which makes it easier for staff to distinguish and process them later.

[0037] Please see Figures 4-5 A rotary motor 14 is installed below the detection chamber 6. The output end of the rotary motor 14 is connected to a toggle block 18 via a screw. The bottom of the tracking block 15 is slidably set with the toggle block 18 along the vertical direction of the screw. The leakage current detection module is connected to the rotary motor 14. By controlling the operation of the rotary motor 14, the screw can drive the toggle block 18 to move back and forth, thereby synchronously driving the tracking block 15 to move along the outer ring of the track plate 13, providing power support for the movement detection of the current measuring brush head 7.

[0038] The end of the screw is mounted to the body 1 via the mounting plate 19. The distance sensor is mounted on the mounting plate 19 and is set in correspondence with the actuating block 18. By detecting the distance between the actuating block 18 and the mounting plate 19, the real-time position of the actuating block 18 can be determined, thereby synchronously positioning the position of the electrical measuring brush head 7 on the molded part 9, providing technical support for the accurate positioning of the insulation paint damage point.

[0039] Please see Figure 3The machine body 1 is equipped with a telescopic motor 11. The output end of the telescopic motor 11 is provided with a connecting plate. The bending disc 3 is rotatably connected to the connecting plate through the main shaft. The connecting plate is equipped with a second rotating motor 10. The output end of the second rotating motor 10 is linked to the main shaft through a gear set. The bending control module is connected to the second rotating motor 10 and the telescopic motor 11 respectively. The bending control module controls the operation of the telescopic motor 11, which can synchronously drive the bending disc 3 and the bending shaft 4 to move up and down. At the same time, working in coordination with the second rotating motor 10, the bending shaft 4 can be moved to both sides of the wire and the wire can be bent to both sides to form a bending shape, which can meet the processing requirements of various bending shapes.

[0040] Example 2 further optimizes the toroidal coil lead bending device provided in Example 1. Unlike Example 1, in order to flexibly control the temperature of the bending shaft 4, please refer to [link to example 2]. Figures 6-8 The temperature control component includes a temperature control cavity 25 and a temperature conduction cavity 28 sequentially formed from the middle of the bending shaft 4 outwards. The tops of the temperature control cavity 25 and the temperature conduction cavity 28 are connected. An inner tube 23 is connected to the outside of the temperature control cavity 25. An outer tube 24 connected to the temperature conduction cavity 28 is fitted around the outer ring of the inner tube 23. The inner tube 23 is used to input the temperature control liquid. A temperature sensor 21 is installed in the temperature control cavity 25. The bending control system also includes a temperature control module. The temperature control module is connected to the bending control module and the temperature sensor 21 respectively. After the temperature control liquid is input into the inner tube 23 at a preset temperature, it flows through the temperature control cavity 25 and the temperature conduction cavity 28 in sequence, and is finally discharged through the outer tube 24. This can quickly adjust the bending shaft 4 to the preset temperature. The temperature sensor 21 can detect the internal temperature of the bending shaft 4 in real time, which is convenient for monitoring its heating status. It should be noted that by setting up a double-layer cavity structure of temperature control cavity 25 and temperature conduction cavity 28, since the temperature conduction cavity 28 is closer to the outer wall of the bending shaft 4, its temperature drops faster than that of temperature control cavity 25; the temperature control liquid in temperature control cavity 25 can slow down the cooling rate of temperature conduction cavity 28, thereby reducing the overall cooling rate of bending shaft 4; by adjusting the temperature of temperature control liquid input to inner tube 23, the temperature of bending shaft 4 can be rapidly regulated. By using the double-layer cavity to suppress the cooling rate, efficient and controllable temperature regulation of bending shaft 4 can be achieved.

[0041] It is worth mentioning that multiple unidirectional valves 30 are installed inside the temperature-conducting cavity 28. The unidirectional valves 30 are fixedly installed in the temperature-conducting cavity 28 by support rods 29. A micro pump 27 is installed in the inner tube 23. The unidirectional valves 30 are used to restrict the unidirectional flow of the temperature-controlled liquid from top to bottom. Under normal conditions, they are in the form of... Figure 7 The unfolded state is shown; when the micro pump 27 starts and draws the temperature control liquid in the inner tube 23 into the temperature control chamber 25, the one-way valve 30 swings downward and retracts (as shown). Figure 8As shown, the temperature-controlled fluid can flow smoothly through the temperature control chamber 25 into the temperature conduction chamber 28, achieving rapid temperature control of the bent shaft 4. After temperature regulation is completed, if it is necessary to maintain a constant temperature for the bent shaft 4, due to the elasticity of the one-way valve 30, the one-way valve 30 will unfold and reset after the micro pump 27 stops working. Due to the one-way restriction of the one-way valve 30, the temperature conduction chamber 28 is divided into multiple independent chambers, and the temperature-controlled fluid is locked in each chamber. Even if the temperature of a single chamber drops, the adjacent chambers can still maintain the preset temperature, ensuring that the bent shaft 4 maintains a relatively stable temperature state. In addition, when it is necessary to rapidly raise or lower the temperature of the bent shaft 4, starting the micro pump 27 can make the temperature-controlled fluid flow rapidly through the temperature control chamber 25, the temperature conduction chamber 28, and the outer tube 24, achieving rapid temperature adjustment. Through the collaborative working logic of the one-way valve 30 and the micro pump 27, rapid temperature control and constant temperature maintenance of the bent shaft 4 are achieved. The multiple independent chamber design of the one-way valve 30 provides a guarantee of temperature stability and further optimizes the temperature control accuracy.

[0042] Because the contact positions between different sections of the bending shaft 4 and the wire vary, uneven surface temperature is easily caused. The aforementioned multi-layered independent chamber design slows down the temperature drop rate of the temperature-conducting cavity 28 and achieves relative uniformity of the surface temperature of the bending shaft 4 through temperature compensation between adjacent chambers. The independent chamber design ensures overall temperature uniformity of the bending shaft, avoiding the risk of insulation varnish damage due to localized temperature differences.

[0043] In addition, an electric heating rod 26 and a hydraulic sensor 20 are installed in the temperature control chamber 25. A heat transfer block 12 is provided between adjacent one-way valves 30. The two ends of the heat transfer block 12 are respectively placed in the corresponding temperature control chamber 25 and the temperature conduction chamber 28. The temperature control module is connected to the electric heating rod 26, the micro pump 27 and the hydraulic sensor 20 respectively. When the bending shaft 4 moves to the easily damaged point D, it needs to be controlled to reach the preset temperature: at this time, the one-way valve 30 is in a state of... Figure 7 As shown, the temperature control module activates the electric heating rod 26 to heat the temperature control fluid in the temperature control chamber 25. Once the temperature reaches the preset value, as detected by the temperature sensor 21, the heat from the temperature control chamber 25 is conducted to the temperature conduction chamber 28 via the heat transfer block 12 and evenly distributed to each chamber segmented by the one-way valve 30, ensuring a uniform and constant external temperature for the bent shaft 4. The temperature control module detects the hydraulic pressure within the temperature control chamber 25 using the hydraulic sensor 20. When the hydraulic pressure is at a preset constant pressure, the one-way valve 30 is determined to be in an open state. Furthermore, when the bent shaft 4 leaves point D, the electric heating rod 26 stops working to save energy. When rapid temperature control of the bent shaft 4 is required, the micro pump 27 is controlled to run, allowing the temperature control fluid to flow rapidly through each chamber, achieving intelligent and precise temperature control. Simultaneously, the hydraulic sensor 20 monitors the state of the one-way valve 30, enabling intelligent control with on-demand temperature regulation and energy saving, thus perfecting the functional closed loop of the temperature control system.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
