Description

Technical Field

[0001] This invention relates to the field of winding device technology, and more specifically, to a lead wire winding device. Background Technology

[0002] Currently, for some induction magnetization products, to meet production process requirements, the two leads of the enameled wire in the main body need to be wound onto the lead wires. However, this wire-to-wire winding is usually done manually, which is inefficient. Although existing technologies include winding devices, such as the dry-type transformer coil winding device and control method disclosed in patent CN114582625A, this involves winding the wire bundle on the iron core, driven by an external drive mechanism to rotate the iron core, and guided by a conductor unit to wind the wire bundle onto the iron core. This method cannot be applied to the finer winding process of connecting the two leads of the enameled wire to the lead wires. Summary of the Invention

[0011] Furthermore, the two pin clamping blocks that are pre-tightened to each other are provided with guide surfaces on their opposite ends so that the pins at one end of the enameled wire can be better pre-fixed between the two pin clamping blocks.

[0012] Furthermore, the guide surface is an arc surface.

[0013] Furthermore, the enameled wire is pre-fixed between a pair of pin clamping blocks via the clamping area.

[0014] Furthermore, the rotary winding mechanism includes a base plate that can move along the clamping direction of the lead wire clamping block by the fifth drive; an upper and lower drive module with the second drive disposed on the base plate; a fourth drive disposed on the upper and lower drive module that can move up and down by the second drive; a pair of clamping fingers connected to the fourth drive; the clamping fingers moving closer or further apart by being driven by the third drive.

[0024] Example

[0025] Combination Figures 1 to 3 As shown, this embodiment provides a lead wire winding device, including a tooling clamping mechanism 1 and a rotary winding mechanism 2; wherein,

[0026] The tooling clamping mechanism 1 includes a base with a limiting protrusion 6. Lead wire clamping blocks 7 are movably disposed on both sides of the protrusion, and clamping areas are formed between the two lead wire clamping blocks 7 and the protrusion. The lead wire clamping blocks 7 approach the limiting protrusion 6 through the action of a first elastic member 8 to clamp the lead wire pin 3, and can move away from the limiting protrusion 6 under the drive of a first drive 13. A product 4 with enameled wire 5 is disposed on the base. A pair of pin clamping blocks 9 are disposed behind the clamping area, and the two pin clamping blocks 9 are pre-tightened through a second elastic member 10 to pre-fix one end of the enameled wire 5.

[0027] The rotary winding mechanism 2 includes a clamping finger 22 located in the winding area below the clamping area. It can move up and down under the drive of the second drive, clamp the enameled wire 5 under the drive of the third drive 23, wind the lead pin 3 under the drive of the fourth drive 21, and move horizontally under the drive of the fifth drive.

[0028] The innovation of this application lies in the coordinated design of the tooling clamping mechanism 1 and the rotary winding mechanism 2, which realizes automated clamping and precise winding of the 5-pin lead of the enameled wire, effectively solving the problem of low efficiency in manual winding. Compared with existing winding devices that rely on manual operation or are only applicable to specific scenarios, this application provides a precise positioning reference through the cooperation of the limiting protrusion 6 and the lead clamping block 7, and realizes automated winding of the 5-pin lead of the enameled wire through multi-drive coordinated control, meeting the high-precision requirements of wire-to-wire winding.

[0029] The working principle of this application embodiment is as follows:

[0030] A lead wire winding device achieves automated clamping and precise winding of enameled wire 5 leads through the coordinated operation of a tooling clamping mechanism 1 and a rotary winding mechanism 2. The tooling clamping mechanism 1, with a base featuring a limiting protrusion 6, provides a precise positioning reference. Movable lead wire clamping blocks 7 are respectively arranged on both sides of the limiting protrusion 6, forming a clamping area between the two clamping blocks 7 and the limiting protrusion 6 to stably clamp the lead wire leads 3. Furthermore, under the action of a first elastic element 8, the lead wire clamping blocks 7 automatically approach the limiting protrusion 6, utilizing the restoring force characteristic of the elastic element to automatically clamp the leads, thereby ensuring consistent clamping force and preventing winding failure due to loosening. Simultaneously, the lead wire clamping blocks 7 can move away from the limiting protrusion 6 under the drive of a first drive 13, facilitating rapid insertion and removal of the lead wire, thus reducing operation time. The base also features a structure for fixing the product 4 containing the enameled wire 5, ensuring the main body remains stable during winding and preventing the product 4 from shaking and affecting winding accuracy.

[0031] A pair of pin clamping blocks 9, positioned below and behind the clamping area, achieve a pre-tightening function through a second elastic element 10. Utilizing the automatic adjustment characteristic of the elastic pre-tightening force, the pins at one end of the enameled wire 5 are reliably pre-fixed between the two pin clamping blocks 9, facilitating the subsequent clamping of the finger 22. Specifically, this pre-tightening design simplifies the initial steps, prevents pin misalignment, and improves the accuracy of clamping the finger 22.

[0032] In the rotary winding mechanism 2, the clamping fingers 22 are positioned in the winding area below the clamping area. Driven by the second drive, they can move up and down to ensure precise positioning. Furthermore, driven by the third drive 23, the clamping fingers 22 move closer to or further away from each other, clamping the enameled wire 5. Precise control of the drive keeps the wire secure during winding, preventing slippage. The clamping fingers 22 can also wind the lead pins 3 under the drive of the fourth drive 21, achieving automated winding through rotational movement, significantly improving efficiency. In addition, driven by the fifth drive, the clamping fingers 22 move horizontally, adjusting the winding position according to the drive's displacement, thus achieving fine winding of the lead pins 3 on the other side, meeting the high-precision requirements of wire-to-wire winding.

[0033] Thus, through the coordinated design of the tooling clamping mechanism 1 and the rotary winding mechanism 2, the device solves the problem of low efficiency in winding the enameled wire 5 pins onto the lead wire feet, and realizes the functions of automated clamping and efficient winding.

[0034] Specifically, in this embodiment, first limiting portions 12 are respectively protruding on both sides of the limiting protrusion 6 on the base; a guide rod 11 is movably passed through the first limiting portion 12, one end of the guide rod 11 is connected to the lead wire clamping block 7; a first elastic element 8 is disposed between the first limiting portion 12 and the lead wire clamping block 7; an opening block 15 is provided at the other end of the guide rod 11. The guide rod 11 is a key component to ensure that the lead wire clamping block 7 moves along a straight trajectory. The first elastic element 8 can be understood as an element that provides automatic reset force, which can be a spring, a sheet, or other elastic structure with similar function, with the purpose of enabling the lead wire clamping block 7 to quickly reset and maintain a stable clamping state. The opening block 15 serves as the operating interface of the external drive mechanism, and its design should facilitate cooperation with the external drive device to achieve uniform force and stable operation.

[0035] In detail, this solution provides a reliable mounting base for the entire guiding mechanism through the first limiting part 12, allowing the guide rod 11 to slide precisely axially within the first limiting part 12. The guide rod 11 is directly connected to the lead wire clamping block 7, ensuring synchronous movement between the two. While providing elastic force between the first limiting part 12 and the lead wire clamping block 7, the first elastic element 8, with the constraint of the guide rod 11, ensures linear movement of the elastic element during its operation, preventing jamming. The introduction of the above structure not only solves the problem of unstable movement of the lead wire clamping block 7, but also significantly improves the reliability of the clamping action and production efficiency.

[0036] Through the above technical solution, the movement of the lead clamping block 7 is strictly limited to a straight trajectory, avoiding lateral offset and wobbling, thereby achieving more precise clamping position control. This improvement optimizes the overall performance of the tooling clamping mechanism 1, laying a solid foundation for the subsequent pre-fixation and winding operations of the enameled wire 5 pins.

[0037] In this embodiment, the first drive 13 is a cylinder, which is connected to an opening arm 14 to act on the opening block 15, thereby causing the lead wire clamping block 7 to overcome the elastic force of the first elastic member 8 and move away from the limiting protrusion 6. By using the cylinder as a power source and combining the linkage design of the opening arm 14 and the opening block 15, a highly efficient force transmission system is formed.

[0038] In this embodiment, the base is provided with a second limiting part 16 protruding downward, and a third limiting part 17 is provided on both sides of the second limiting part 16; of the two pin clamping blocks 9 that are pre-tightened to each other, one pin clamping block 9 is fixed on the side wall of the second limiting part 16, and the other pin clamping block 9 is connected to the third limiting part 17 through the second elastic member 10.

[0039] Specifically, the second limiting part 16 refers to a rigid support structure extending downward from the base. It can be integrally formed of metal or welded to the base, and its purpose is to provide a stable mounting reference for the pin clamping block 9. The third limiting part 17 can be understood as an auxiliary positioning structure used in conjunction with the second limiting part 16. It can be fixed to both sides of the second limiting part 16 by bolt connection or snap-fit, and is used to achieve elastic connection of the other pin clamping block 9. In practical applications, the second elastic element 10 is usually selected from elastic components such as springs or rubber pads to ensure uniform distribution of preload.

[0040] In detail, this technical solution provides a rigid support point through the second limiting part 16, allowing one pin clamping block 9 to be firmly fixed to the side wall, thus avoiding possible displacement during operation. Simultaneously, the design of the third limiting part 17 creates elastic connection conditions for the other pin clamping block 9. Guide surfaces 18 are provided on the opposite ends of the two pin clamping blocks 9 to better pre-fix the pin at one end of the enameled wire 5 between the two pin clamping blocks 9. Specifically, the guide surface 18 refers to a guiding surface structure designed on the opposite ends of the pin clamping blocks 9, which can be implemented using an arc surface, a slope, or other smoothly transitioned curved surface. Its purpose is to provide a smooth guide path for the pin of the enameled wire 5, avoiding jamming or offset caused by irregular end faces, thereby improving the efficiency and stability of pre-fixation.

[0041] In detail, this solution effectively solves the problem of difficulty in aligning and sliding the enameled wire 5 pins into the clamping area during pre-fixation by setting guide surfaces 18 on the opposite ends of the two pin clamping blocks 9. Based on the stable clamping force generated by the elastic element, the two pin clamping blocks 9 ensure uniform force on the pins during pre-fixation; while the design of the guide surfaces 18 further optimizes the pin introduction process, allowing them to slide naturally into the clamping area along the guide surfaces 18. This structural design not only improves the smoothness of operation but also enhances the reliability of pre-fixation, providing a fundamental guarantee for subsequent fine winding. Furthermore, the aforementioned pin clamping blocks 9, together with the limiting part on the base and the elastic element, form a complete pre-fixation system, further improving the overall working efficiency and accuracy of the device.

[0042] Through the above technical solution, the pre-fixing process of the 5-pin enameled wire is more efficient and stable, significantly improving the user experience and laying a solid foundation for the subsequent winding process.

[0043] In this embodiment, the enameled wire 5 is pre-fixed between a pair of pin clamping blocks 9 after passing through the clamping area. Specifically, this technical solution ensures that the enameled wire 5 must first pass through the clamping area before being pre-fixed, so as to facilitate the subsequent gripping by the clamping finger 22.

[0044] In this embodiment, the rotating winding mechanism 2 includes a base plate 19 that can move along the clamping direction of the lead wire clamping block 7 via a fifth drive (not shown in the figure); an up-down drive module 20 with a second drive disposed on the base plate 19; a fourth drive 21 disposed on the up-down drive module 20 that can move up and down via the second drive (not shown in the figure); and a pair of clamping fingers 22 connected to the fourth drive 21; the clamping fingers 22 move closer to each other or further apart under the drive of a third drive 23.

[0045] Specifically, the base plate 19 refers to the basic component used to support and bear the entire rotary winding mechanism 2. It can be made of metal sheet or other high-strength materials to provide a stable mounting platform and ensure the rigidity of the overall structure. The fifth drive can be a power device such as a linear motor, lead screw drive mechanism, or cylinder to achieve horizontal movement. Its purpose is to precisely control the horizontal displacement of the base plate 19 along the clamping direction of the lead wire clamping block 7, thereby achieving precise alignment with the clamping area. In practical applications, the up-down drive module 20 can be understood as a modular component capable of providing vertical movement. It may consist of a guide rail slider system combined with a servo motor or stepper motor, aiming to achieve flexible height adjustment so that the enameled wire 5 can be gradually wound onto the lead wire pin 3 from top to bottom or from bottom to top. The fourth drive 21 uses a rotary motor to drive the clamping fingers 22 to rotate. The clamping finger 22 is designed to reliably clamp the enameled wire 5. Its opening and closing action is controlled by the third drive 23, which can be implemented by a miniature cylinder or an electric push rod. The purpose is to reduce manual intervention and improve clamping accuracy and efficiency through automated operation.

[0046] In summary, the above technical solutions not only solve the problems of inaccurate positioning and unstable movement during the winding process, but also significantly improve the accuracy and efficiency of the winding operation, providing a reliable solution for the production process of the induction magnetization product 4.

[0047] In this application, the clamping finger 22 is eccentrically configured to drive the winding lead pin 3 to rotate around in a circular motion via the fourth drive 21.

[0048] Specifically, the clamping finger 22 refers to the actuating component used to clamp and wind the enameled wire 5, which can be implemented using a mechanical finger with an eccentric structure. In practical applications, the eccentric design of the clamping finger 22 ensures that when the fourth drive 21 rotates the clamping finger 22 around the lead pin 3, the eccentric structure ensures that the clamping finger 22 always rotates around the lead pin 3. During rotation, the enameled wire 5 dynamically conforms to the contour of the lead pin 3, thereby ensuring that the enameled wire 5 receives uniform pressure during winding. It should be noted that when the clamping finger 22 drives the enameled wire 5 to wind, one end of the enameled wire 5 detaches from the pre-fixed position to form a free end, facilitating the movement of the clamping finger 22.
