In existing technology, the winding arm is typically wound on one side only. High-speed rotation during winding can easily lead to imbalance and instability, resulting in slower winding speeds and reduced efficiency. Therefore, improvements can be made to existing stator core winding methods. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a winding robot that solves the issue of poor balance in existing single winding arms, which limits winding speed.

[0010] A further improvement to the above scheme is that the winding positioning frame includes a first push rod, a mounting base connected to the first push rod, and a positioning slide rail mounted on the mounting base. The first push rod passes through the lead wire device and is movable within the lead wire device. The second positioning component is mounted on the positioning slide rail. A second push rod is provided inside the first push rod, and the second push rod is connected to the first positioning component. Limit blocks are installed at both ends of the positioning slide rail.

[0011] A further improvement to the above solution is that the first positioning component includes a first slider, a first buffer element connected to the first slider, a positioning guide block connected to the mounting base, and a first positioning element connected to the positioning guide block and abutting against the first buffer element.

During the winding process, the iron core or magnetic core is placed in the placement position. After the iron core is positioned by the cooperation of the placement position and the winding positioning device, the lead wire device introduces the wire into the conductor device. The conductor device winds the copper wire onto the iron core by rotating the winding element around the iron core. Attached Figure Description

Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0032] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] like Figures 1-10 As shown, a winding robot for winding iron core 5 includes a placement position 1, a lead wire device 2, a wire guide device 3, and a winding positioning device 4. The lead wire device 2 faces the placement position 1, and the winding positioning device 4 is used for positioning the iron core 5 during winding. The lead wire device 2 has a connection position 21. The wire guide device 3 includes a winding element 31 and a balancing element 32. The winding element 31 and the balancing element 32 are symmetrically installed on the connection position 21. The winding element 31 extends towards the placement position 1. The rotation of the connection position 21 drives the winding element 31 and the balancing element 32 to rotate. The rotation of the winding element 31 winds the wire onto the iron core 5.

[0035] See Figure 3 As shown, placement position 1 includes a fixing component 11 for fixing the iron core 5 and a positioning clamping member 12 for fixing the outer periphery of the iron core 5. The positioning clamping member 12 is provided with a clamping groove 121, which is used for positioning the outer periphery of the iron core 5. In this embodiment, the iron core 5 is pressed and fixed by the fixing component 11 in conjunction with the fixing clamping member, and the clamping groove 121 is used to fix the iron core 5 according to its shape, resulting in better stability during winding. A positioning clamping block 121a is provided in the clamping groove 121a, and a clamping groove 121b is provided corresponding to the iron core for clamping and positioning the iron core.

[0036] See Figure 3 As shown, the fixing assembly 11 includes a drive connecting element 111 and a mounting element 112 mounted on the drive connecting element 111. The iron core 5 is mounted on the mounting element 112. The iron core 5 includes a fixing ring 51 and a winding portion 52 arranged circumferentially on the fixing ring 51. The inner diameter of the fixing ring 51 is provided with a fixing groove 511. The mounting element 112 is provided with a mounting platform 112a. The mounting platform 112a is provided with a positioning strip 112b. The positioning strip 112b cooperates with the fixing groove 511. In a further preferred embodiment, the iron core 5 is provided with a fixing ring 51 and a circumferentially distributed winding portion 52, thereby forming a coil structure of a motor. During operation, the drive connecting element 111 drives the mounting element 112 to drive the iron core 5 to rotate. During rotation, the positioning strip 112b and the fixing groove 511 cooperate to ensure stable rotation, and copper wire can be wound onto the winding portion 52 in sequence.

[0037] The placement position 1 is provided with protective plates 13 on both sides. The protective plates 13 are provided with guide grooves 131. The guide grooves 131 are used for positioning the outer periphery of the iron core 5. The guide grooves 131 are provided with baffles 132 on both sides.

In the above embodiment, in order to better guide and position the iron core 5 during winding rotation, the protective plates 13 are provided for outer periphery positioning, and the baffles 132 are used for positioning protection to prevent the copper wire from falling into the winding parts 52 on both sides during winding.

[0038] See Figure 4 As shown, the lead wire device 2 includes a winding drive unit 22, a connecting position 21 fixedly connected to the winding drive unit 22, a ramp 211 provided on the connecting position 21, a fixing groove 212 provided on the ramp 211, a winding element 31 adjustablely mounted on the fixing groove 212, and a wire-passing hole 311 connected to a winding ring 312. In this embodiment, through the cooperation of the winding drive unit 22 and the connecting position 21, when the winding drive unit 22 rotates, the winding element 31 rotates to wind the copper wire onto the winding part 52 of the iron core 5. After the copper wire passes through the wire-passing hole 311, it is guided by the winding ring 312, and the guidance is stable. More preferably, the wire-passing hole 311 has a magnetic ring for the copper wire to pass through, preventing scratches on the insulation layer of the enameled wire.

[0039] See Figures 6-10 As shown, the winding positioning device 4 includes a winding positioning frame 41, a first positioning component 42 and a second positioning component 43 mounted on the winding positioning frame 41. The first positioning component 42 is used to fix the two sides of the iron core 5, and the second positioning component 43 is used to fix the upper and lower surfaces of the iron core 5. In this embodiment, the two positioning components cooperate to fix the two sides and the upper and lower surfaces of the iron core 5 respectively, forming a four-sided fixing structure, which provides better stability and higher accuracy during winding. In a further preferred embodiment, the first positioning component 42 and the second positioning component 43 are provided with avoidance slopes near the position where the iron core 5 is fixed, so that there will be no obstruction during winding.

[0040] In a further preferred embodiment, the winding positioning frame 41 includes a first push rod 411, a mounting base 412 connected to the first push rod 411, and a positioning slide rail 413 mounted on the mounting base 412.

A second push rod 414 is provided inside the first push rod 411, and the second push rod 414 is connected to the first positioning component 42. Limit blocks 413a are installed at both ends of the positioning slide rail 413. During winding, the first push rod 411 moves within the lead wire device 2, so that the first positioning component 42 positions the two sides and end faces of the iron core 5. After positioning, during the movement, the second positioning component 43 moves along the positioning slide rail 413. During the movement, the two ends of the iron core 5 can be positioned, resulting in a good positioning effect. Limit blocks 413a are provided to limit the second positioning component 43.

The mounting base 412 has a positioning slide groove 412a for sliding the first slider 421 and a positioning guide groove 412b for moving the positioning guide block 423. In a preferred embodiment, the first buffer element 422 is a spring, which can play a buffering role during the positioning process to prevent damage to the iron core 5. Moreover, the cooperation between the first slider 421 and the positioning guide block 423 ensures the accuracy of the structure during movement. The positioning groove 424a cooperates with the end face and both sides of the winding part 52 of the iron core 5 for positioning, resulting in high positioning accuracy. The positioning slide groove 412a and the positioning guide groove 412b cooperate to slide, further ensuring the moving accuracy of the structure. The movement is guided by the push rod, resulting in high accuracy.

[0042] The second positioning component 43 includes an upper positioning claw 431 and a lower positioning claw 432. The upper positioning claw 431 and the lower positioning claw 432 are symmetrical and slidably mounted on the positioning slide rail 413. The upper positioning claw 431 is provided with an upper sliding member 433, and the lower positioning claw 432 is provided with a lower sliding member 434. A tension element 435 is provided between the upper sliding member 433 and the lower sliding member 434. In this embodiment, the upper positioning claw 431 and the lower positioning claw 432 are used to position the upper and lower surfaces of the iron core 5, respectively. During positioning, the positioning slide rail 413 guides the sliding, resulting in high accuracy. In a preferred embodiment, a tension element 435 is also provided to connect the upper positioning claw 431 and the lower positioning claw 432, thereby pressing and positioning the two surfaces of the iron core 5.

[0043] See Figure 10As shown, the first slider 421 has a first push platform 421a and a second push platform 421b on its upper and lower sides, respectively. The upper slider 433 has a first push pulley 433a corresponding to the first push platform 421a, and the lower slider 434 has a second push pulley 434a corresponding to the second push platform 421b. The first push platform 421a pushes the first push pulley 433a, causing the upper slider 433 to move the upper positioning claw 431 along the positioning slide rail 413. The second push platform 421b pushes the second push pulley 434a, causing the lower slider 434 to move the lower positioning claw 432 along the positioning slide rail 413. In a preferred embodiment, the push platform and the push pulley together move the positioning claw on the positioning slide rail 413. When further combined with the tension element 435, the opening and closing action of the two positioning claws is realized.

[0044] The upper and lower sides of the positioning groove 424a are respectively provided with an upper groove 424b and a lower groove 424c. The upper positioning claw 431 can move in the upper groove 424b, and the lower positioning claw 432 can move in the lower groove 424c.

The first positioning hook 431a and the second positioning hook 432a are respectively connected to the upper and lower sides of the positioning groove 424a. In the preferred embodiment, the two positioning hooks are at the upper and lower ends of the positioning groove 424a, so that the groove surface of the positioning groove 424a and the two positioning hooks form a four-sided positioning structure for positioning the winding part 52 of the iron core 5, which improves the structural stability during winding.

[0045] This invention features a symmetrically mounted winding element 31 and balancing element 32 on the lead wire device 2. This ensures balance during winding rotation, solving the problem of poor balance and slow winding speeds inherent in existing single-arm winding systems. The symmetrically arranged balancing structure enables high-speed winding, thus improving production efficiency. Specifically, the invention includes a placement position 1, a lead wire device 2, a wire guide device 3, and a winding positioning device 4. The lead wire device 2 faces the placement position 1, and the winding positioning device 4 is used for positioning the iron core 5 during winding. The lead wire device 2 has a connection position 21. The wire guide device 3 includes a winding element 31 and a balancing element 32. The winding element 31 and the balancing element 32 are symmetrically mounted on the connection position 21. The winding element 31 extends towards the placement position 1. Rotation of the connection position 21 causes the winding element 31 and the balancing element 32 to rotate, and the rotation of the winding element 31 winds the wire onto the iron core 5. During the winding process, the iron core 5 or magnetic core is placed in the placement position 1. After the iron core 5 is positioned by the cooperation of the placement position 1 and the winding positioning device 4, the lead wire device 2 introduces the wire into the conductor device 3. The conductor device 3 winds the copper wire around the iron core 5 by rotating the winding element 31 around the iron core 5.
