[0027] The present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1-8As shown, a high-precision stator winding device can be divided into two parts. One part is used for adjusting the position of the enameled wire 28, which is divided into three major parts: a horizontal moving device 3, a vertical moving device 4 and a longitudinal moving device 5. The other part is divided into four major parts. The enameled wire 28 passes through the clamping device 6, the paint scraping device 7, the shearing device 8 in sequence and finally reaches the stator clamping and winding device 9 to complete the entire stator winding process.

[0028] The present invention has two winding lines, which can simultaneously perform winding assembly on two stators. The structures and principles of the two lines are the same, except that the two lines share a position adjustment device. The following will take one line to illustrate the above structure separately: the above structures are all installed on a workbench 1, and a wire barrel 2 containing enameled wire 28 is placed next to the workbench 1. A conductor post is provided on the workbench 1 directly above the wire barrel 2. The enameled wire 28 first passes through the conductor post and then reaches the clamping device 6, wherein the clamping device 6, the paint scraping device 7, and the shearing device 8 are all installed on the device fixing part 12, and the lateral moving device 3, the vertical moving device 4 and the longitudinal moving device 5 are fixed in sequence at the bottom of the device fixing part 12, and the position adjustment of several structures installed on the device fixing part 12 in three-dimensional space is completed through these three devices.

[0029] First, let's explain the position adjustment device. The cross section of the workbench 1 is "concave", and the three position adjustment devices are installed in the "concave" of the workbench 1. The horizontal moving device 3 includes three parts: a cylinder 15, a horizontal sliding mounting member 301, and a linear rail 16. The horizontal sliding mounting member 301 is fixed to the side of the workbench 1, and the linear rail 16 is respectively fixed to the upper and lower ends of the side of the horizontal sliding mounting member 301. The power required for movement is provided by the cylinder 15, and the cylinder 15 is fixed on the horizontal sliding mounting member 301. Its transmission rod is fixedly connected to the vertical moving device 4. The vertical moving device 4 and the device connected thereto are moved horizontally by contraction of the transmission rod of the cylinder 15, so as to achieve To adjust the horizontal horizontal position; the vertical moving device 4 includes three components: a cylinder 15, a vertical sliding mounting member 401, and a linear rail 16. Its installation and connection method is the same as that of the horizontal moving device 3, except that the vertical sliding mounting member 401 is slidably mounted on the linear rail 16 of the horizontal moving device 3. In order to facilitate the fixation of the linear rail 16 of the vertical moving device 4, a bearing seat 10 is provided on the vertical moving device 4. The bearing seat 10 is used to carry and install other device structures. The linear rail 16 of the vertical moving device 4 is fixed to the side of the bearing seat 10 and is slidably connected to the vertical sliding mounting member 401. In order to enable the bearing seat 10 to achieve the purpose of vertical movement, The cylinder 15 of the vertical moving device 4 is fixed on the vertical sliding mounting member 401, and the transmission rod of the cylinder 15 is fixedly connected to the bearing seat 10. However, it is undoubtedly difficult for a single cylinder 15 to achieve the purpose of vertically moving the entire bearing seat 10 and other device structures installed on the bearing seat 10. For this reason, a fixed connecting member 13 and two lifting cylinders 14 are also provided on the side of the bearing seat 10. The cross-section of the fixed connecting member 13 is "L"-shaped, and its two ends are fixed on the vertical sliding mounting member 401. The bearing seat 10 passes through the fixed connecting member 13, and the lifting cylinder 14 is fixed on the bearing seat 10 as a whole. The transmission rod of the lifting cylinder 14 is fixedly connected to the fixed connecting member 13, and the lifting cylinder 14 is fixedly connected to the vertical sliding mounting member 401. The cylinders 15 and the lifting cylinders 14 on both sides of the carrier 10 can easily move the carrier 10 vertically up and down, and the lifting cylinders 14 can also fix the carrier 10 more firmly; the longitudinal moving device 5 is located on the upper part of the carrier 10 and is installed and fixed on the bottom of the sliding base 11. The linear rail 16 of the longitudinal moving device 5 is fixed on the bottom of the sliding base 11. The sliding base 11 is slidably connected to the carrier 10 through the linear rail 16. The cylinder 15 of the longitudinal moving device 5 is fixed on the bottom of the sliding base 11, and its transmission rod is fixedly connected to the carrier 10. The sliding base 11 and other device structures installed on the sliding base 11 are driven to move longitudinally by the telescopic transmission rod of the cylinder 15.

[0030] The principles of the three moving devices are the same. The clamping device 6, the paint scraping device 7 and the shearing device 8 are respectively located on both sides of the upper part of the sliding base 11 to form two lines. In order to facilitate the installation of the paint scraping device 7 and the shearing device 8 and make their division of labor more detailed, a device fixing part 12 is also installed at the right end of the upper part of the sliding base 11. The two devices are installed on the device fixing part 12.

[0031] The specific process and principle of stator winding will be explained below. The enameled wire 28 in the wire barrel 2 passes through the wire clamping device after being turned by the guide column 25. The wire clamping device is used to fix the enameled wire 28 and squeeze the enameled wire 28 between the clamping device 6 and the inner wall of the sliding base 11, so as to fix the enameled wire 28 to prevent it from sliding and affecting the subsequent winding; then the enameled wire 28 will pass through the paint scraping device 7, and the paint on the outer surface of the enameled wire 28 will be scraped off by the scraping claw mechanism 701. In order to facilitate the installation and opening of the scraping claw mechanism 701, a cylinder 15, a slide rail 17, a connecting block 702, a scraping claw mounting member 703, a wire transmission mechanism 704, a scraping claw telescopic member 705 and a limit member 706 are also arranged on the device fixed seat 906. The scraping claw mechanism 70 1 is located inside the scraper claw mounting member 703, the wire transmission mechanism 704 is installed at the end of the scraper claw mounting member 703, the scraper claw telescopic member 705 passes through the wire transmission mechanism 704 and is connected to the scraper claw mechanism 701 inside the scraper claw mounting member 703, the enameled wire 28 will pass through the scraper claw telescopic member 705, the wire transmission mechanism 704 and the scraper claw mechanism 701, and then extend outward through the shearing device 8. During the paint scraping operation, when the scraper claw telescopic member 705 is extended to the outside of the scraper claw mounting member 703, the scraper claw mechanism 701 will be pulled, so that the scraper claw mechanism 701 closes and clamps the enameled wire 28 and drags it backwards, so that the paint outside the enameled wire 28 is scraped off. This process cannot be done manually, and the cylinder 15 here is used to provide power. The cylinder 15 and the slide rail 17. The limiter 706 is arranged parallel to the scraper claw telescopic member 705. The cylinder 15 is fixed on the device fixing member 12. The slide rail 17 and the limiter 706 are installed on the side of the device fixing member 12. One end of the connecting block 702 is slidably connected to the slide rail 17, and the other end is fixedly connected to the scraper claw telescopic member 705. The transmission rod of the cylinder 15 will pass through the limiter 706 and be fixedly connected to the connecting block 702. When the transmission rod of the cylinder 15 is extended or retracted, it will drive the scraper claw telescopic member 705 to complete the paint scraping process. After the paint is scraped, the wire transmission mechanism 704 will transmit the enameled wire 28 to the outside of the scraper claw mounting member 703, and transmit it to the next device through the device fixing member 12; at the position on the device fixing member 12 and facing the scraper claw mechanism 701 A manual clamping part 24 is also installed to clamp the enameled wire 28; when the wire transmission mechanism 704 transmits the enameled wire 28, power support is required, so a motor 19 and a transmission wheel 21 are also installed in the middle of the device fixing part 12, and the motor 19, the transmission wheel 21 and the wire transmission mechanism 704 are connected by a transmission belt 20. When the motor 19 rotates, the transmission belt 20 will drive the wire transmission mechanism 704 to rotate, and the wire transmission mechanism 704 will work to transmit the enameled wire 28. One motor 19 can provide power for two wires; paint dust will be generated in the process of scraping paint and cannot be removed. For this reason, a dust suction pipe 22 is installed at the lower part of the scraper claw device, and the pipe mouth is facing the scraper claw mechanism 701. The dust suction pipe 22 is externally connected to a vacuum cleaner, which scrapes and sucks at the same time to prevent paint dust from remaining.

[0032] The part of the enameled wire 28 where the paint is scraped off needs to be cut off from the middle by the shearing device 8, and the two cut ends are respectively used as the welding ends of the two stators to be wound. After one stator is wound, the cut end of the enameled wire 28 will be used as the welding end of the next stator wire group; the shearing device 8 is composed of an electric cylinder 18, a fixed rod 801 and a shear 802. The electric cylinder 18 is installed on the device fixing part 12 at a certain angle and is located in the middle position of the device fixing part 12 near the end. The middle part of the fixed rod 801 is horizontally fixed on the electric cylinder 18. The shear 802 is respectively installed and fixed on the two ends of the fixed rod 801 to shear the two wires. Through the electric cylinder 18, the fixed rod 801 can be tilted and slid so that the shear 802 is close to the enameled wire 28 to be cut to complete the shearing. The angle between the shear 802 and the enameled wire 28 to be cut can be adjusted manually, and the flexibility is very high.

[0033] The sheared enameled wire 28 will reach the stator clamping and winding device 9, and the stator clamping and winding device 9 will complete the stator winding. Next, it will be explained how the stator is wound. The whole device is installed on the workbench 1, close to the shearing device 8, and is mainly composed of a bracket 901, an electric cylinder 18, a positioning member 902, a winding motor 903, a steering motor 904, a transmission belt 20, a steering platform 905, a fixing seat 906, a calibration cylinder 907, a stator fixing member 908, a transmission member 909 and other components. The function of the bracket 901 is to facilitate the installation of the cylinder 15 so as to clamp the stator later. This device can perform winding operations on two stators at the same time. Two electric cylinders 18 are installed vertically and parallel on the bracket 901, a fixing seat 906 is installed at the end of the electric cylinder 18, and a calibration cylinder 907 is installed horizontally on the fixing seat 906. The positioning member 902 passes through the fixing seat 906 and is installed at the bottom of the fixing seat 906. The upper end of the positioning member 902 is a flat surface. First, loosen the screws that fix the positioning member 902, then push the flat surface of the positioning member 902 through the calibration cylinder 907 to align the position of the positioning member 902, and then tighten the screws to calibrate the position of the positioning member 902. When the positioning member 902 is subjected to a large torsional force, its lower end will rotate and rotate synchronously with the stator fixing member 908 installed at the end of the turning platform 905; the stator fixing member 908 is used to place the stator, passes through the turning platform 905 and is fixed at both ends, and is slidably engaged with the transmission member 909 embedded in the workbench 1 near the shearing device 8, and the turning platform 905 is installed on the workbench 1, and its lower end is connected to the steering motor 904 installed inside the workbench 1, and the steering platform 905 is rotated by the steering motor 904; the winding motor 903 is installed inside the workbench 1 and is connected to the transmission member 909 through the transmission belt 20, and the stator fixing member 908 is driven by the winding motor 903 through the transmission belt 20 to rotate, completing the winding operation.

[0034] When the stator is winding, the enameled wire 28 in the wire barrel 2 passes through each device in turn. During the first operation, the distance between the end of the enameled wire 28 extending from the device fixing part 12 and the paint scraping mechanism is exactly the circumference of the stator. Then, the enameled wire 28 is fixed by the clamping device 6 and the manual clamping part 24, and the paint on the outer layer of the enameled wire 28 is scraped off by the paint scraping device 7. Then, the enameled wire 28 is released, and the motor 19 drives the wire conveying mechanism 704 to convey the enameled wire 28, so that the enameled wire 28 is conveyed to the position of the stator fixing part 908; the stator fixing part 908 The stator fixing part 908 is originally separated from the transmission part 909, and a part of the stator fixing part 908 can slide up and down. First, the end of the enameled wire 28 without paint is inserted into the slot of the stator fixing part 908 where the stator is placed. The electric cylinder 18 on the bracket 901 will move the positioning part 902 downward, clamp the stator together with the stator fixing part 908, and apply a downward force to the stator fixing part 908, forcing the stator fixing part 908 to sink and engage with the transmission part 909. In this process, the enameled wire 28 will be clamped, and the winding motor 903 starts. The stator fixing member 908 is driven to rotate by the transmission belt 20, so that the stator rotates, and finally the enameled wire 28 is wound on the stator. Since the stator is not circular, the clamping device 6, the paint scraping device 7 and the shearing device 8 need to be constantly adjusted in the process of winding, so that the enameled wire 28 is perfectly wound on the stator, and finally the winding operation is completed; when a stator is about to complete the winding operation, the paint scraping device 7 scrapes the paint on the enameled wire 28, and then the shearing device 8 scrapes the paint from the middle position of the enameled wire 28 where the paint is scraped off. To start cutting, a portion of the length of the enameled wire 28 needs to be reserved in advance, that is, the distance from the stator fixing part 908 to the shear 802, which is equal to the length of the remaining number of turns of the stator winding; when the paint scraping device 7 completes the winding operation of a stator, the positioning part 902 rises, the stator fixing part 908 returns to its original natural state, and the steering motor 904 rotates the steering table 905 to swap the two ends of the steering table 905. The end of the enameled wire 28 that is removed and cut off becomes the new stator winding fixed end, and then the above steps are repeated to complete the winding operation of the next stator.

[0035] It should be noted that the turning platform 905 and the stator fixing part 908 may cause position deviation after being rotated for a long time, so positioning notches are set at both ends of the turning platform 905 and the side of the lower end of the stator fixing part 908, and a positioning cylinder 911, a slide rail 17 and a positioning block 910 are installed next to the positioning notch of the turning platform 905. The positioning cylinder 911 and the slide rail 17 are fixed on the workbench 1, and the positioning block 910 is installed on the transmission rod of the cylinder 15, and the end of the positioning block 910 is adapted to the positioning notch; first First, loosen the screws at the connection between the steering platform 905 and the steering motor 19, and then push the positioning block 910 through the positioning cylinder 911 to make the end of the positioning block 910 completely fit into the positioning slot, thereby completing the positioning, and finally tighten the screws; based on the same principle, a calibration component 23 is provided next to the positioning slot of the stator fixing component 908, and the calibration component 23 is installed and fixed on the bottom of the steering platform 905 and its end is matched with the positioning slot, but this requires manual adjustment of the calibration component 23 to complete the position calibration.

[0036] In the winding equipment provided by the present invention, there are many places where the cylinder 15 is used as a power source. Therefore, a pressure reducing valve 26 and a pneumatic triplet 27 are installed on the side of the workbench 1 to provide air pressure for the cylinder 15 and control the stability of the air pressure in the entire equipment.

[0037] The above is an explanation of the specific structure and working principle of the entire device of the present invention.

[0038] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present invention and fall within the protection scope of the present invention.
