Description

Technical Field

[0001] This invention relates to a wire covering device for a winding machine and a winding machine. Background Technology

[0002] A winding machine is a specialized automated device that winds enameled wire, cotton-covered wire, and other wires according to specific rules (such as the number of layers, turns, and shape) onto products such as transformer frames, inductor cores, and motor stators. In winding machines, the covering device mostly adopts a single-sided or double-sided covering structure, meaning that the sample is covered from a single direction or two opposite directions through one or two covering heads. This structure results in severely uneven circumferential stress on the sample, large variations in the thickness of the covering layer, and a tendency for problems such as localized loose covering leading to wire displacement or localized over-tight covering leading to insulation damage, seriously affecting the electrical performance of the product. Furthermore, single-sided or double-sided covering requires the sample to rotate, which can easily cause runout for long-axis samples, further reducing the covering accuracy. Moreover, the lack of a pressure detection device on the covering head makes it impossible to ensure consistent covering pressure during the process, easily leading to excessive pressure damaging the sample or insufficient pressure resulting in incomplete covering, resulting in a high scrap rate. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of high scrap rate caused by the inability of existing coating devices to adjust the coating pressure in real time. This invention proposes a coating device for a winding machine, which uses a pressure sensor installed on the coating unit to detect the coating pressure in real time. The device can adjust the position of the coating unit in real time according to the pressure signal, thereby ensuring that the pressure remains consistent during the coating process, avoiding damage to the sample due to excessive coating pressure, improving the uniformity of the coating layer, and reducing the scrap rate.

[0019] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0020] Example 1: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a wire covering device for a winding machine includes a fixed plate 1 and several wire covering units 2. The fixed plate 1 has a through hole 11 in the middle for the sample to pass through. The several wire covering units 2 are evenly arranged along the outer circumference of the through hole 11 and are movably connected to the fixed plate 1. The wire covering unit 2 is provided with a cutting part 3 for cutting the end of the wire 10 and a pressure sensor 4 for detecting the wire covering pressure. A heating unit 5 for heating the surface of the sample is provided on the fixed plate 1 on one side of each wire covering unit 2.

[0021] The pressure sensor 4 installed on the coating unit 2 detects the coating pressure in real time, and the position of the coating unit 2 can be adjusted in real time according to the pressure signal, thereby ensuring that the pressure remains consistent throughout the coating process, avoiding damage to the sample due to excessive coating pressure, improving the uniformity of the coating layer, reducing the scrap rate, and allowing the coating pressure to be adjusted according to different samples to meet different winding requirements. In addition, the cutting part 3 installed on the coating unit 2 can automatically cut the wire 10 during the wire laying process without manual intervention, improving production efficiency, and ensuring that the cutting position accurately coincides with the coating end point, with no excess wire residue, resulting in good product appearance consistency. Secondly, the heating unit 5 is also included. The sample surface can be heated to control the temperature of the wire application point, ensuring optimal adhesion between the wire 10 and the sample surface. This prevents the coating layer from peeling off due to decreased adhesion after the sample cools. Furthermore, a heating unit 5 is provided on one side of each wire application unit 2, allowing for individual control of the heating temperature of each unit 5. This compensates for temperature differences at different locations, ensuring uniform heating temperature at all points around the sample and further improving the stability of the wire application quality. Finally, several wire application units 2 are evenly arranged along the outer circumference of the through hole 11, enabling simultaneous wire application to the sample from multiple directions. This ensures uniform force distribution around the sample, improving both wire application efficiency and quality.

[0022] The overlay unit 2 includes a linear guide rail 21, a first slider 22, a second slider 23, and an overlay head 24. The linear guide rail 21 is fixedly mounted on a fixed plate 1. The first slider 22 and the second slider 23 are both slidably connected to the linear guide rail 21. The fixed plate 1 is provided with a drive assembly 6 for driving the first slider 22 to move linearly on the linear guide rail 21. The drive assembly 6 includes a drive part 61 and a lead screw and nut transmission part 62. The drive part 61 is connected to the lead screw and nut transmission part 62. The lead screw and nut transmission part 62 is provided with an elastic transmission element 63 for driving the second slider 23 to move linearly on the linear guide rail 21. The overlay head 24 is mounted on the second slider 23. The pressure sensor 4 is disposed on the overlay head 24 and the second slider 23. Between the second slider 23; the overlay unit 2 is configured as a structure of linear guide rail 21, first slider 22, second slider 23 and overlay head 24. Since the first slider 22 and the second slider 23 are both slidably connected on the linear guide rail 21, the straightness of the movement of the first slider 22 and the second slider 23 can be guaranteed. In addition, the first slider 22 is driven by the drive component 6 and the second slider 23 is driven by the elastic transmission component 63, which can effectively buffer the overlay pressure of the overlay head 24 and improve the overlay accuracy. The pressure sensor 4 is set between the overlay head 24 and the second slider 23, which can directly and accurately detect the contact pressure during overlay, and facilitate subsequent adjustment of the output of the drive component 6 based on the pressure data to form a closed-loop control and ensure that the overlay pressure is stable within a suitable range.

[0023] The drive unit 61 includes a fixed frame 611 and a servo motor 612. The screw and nut transmission unit 62 includes a transmission screw 621 and a transmission nut 622. The fixed frame 611 is fixedly mounted on the fixed plate 1, the servo motor 612 is fixedly mounted on the fixed frame 611, the transmission screw 621 is fixedly mounted on the motor shaft of the servo motor 612, the transmission nut 622 is disposed on the transmission screw 621, and the first slider 22 is disposed on the transmission nut 622. The elastic transmission component 63 includes a sliding sleeve 631 and a spring 632 sleeved on the outer wall of the sliding sleeve 631. One end of the spring 632 abuts against the first slider 22, and the other end of the spring 632 abuts against the second slider 23. The sliding sleeve 631 is fixedly mounted on the transmission nut 622, and the second slider 23 is fixedly mounted on the sliding sleeve 631. By configuring the drive unit 61 with a structure of a fixed frame 611 and a servo motor 612, the fixed frame 611 ensures that the servo motor 612 is stably mounted on the fixed plate 1, and the screw and nut transmission unit... Part 62 is configured as a transmission screw 621 and a transmission nut 622. Since the transmission screw 621 is fixedly mounted on the motor shaft of the servo motor 612, the rotation speed and rotation angle of the transmission screw 621 can be precisely controlled, thereby accurately controlling the stroke and speed of the first slider 22. The transmission nut 622 provides smooth transmission, ensuring the stability of the sliding of the first slider 22. Finally, the elastic transmission component 63 is configured as a sliding sleeve 631 and a spring 632. The sliding sleeve 631 ensures that the spring 632 is always compressed axially, avoiding radial offset that could cause the second slider 23 to tilt. It can also limit the maximum stroke of the second slider 23, preventing the spring 632 from being over-compressed and damaged, and the wire-covering head 24 from being over-pressed and damaging the sample. When the wire-covering head 24 contacts the sample, the spring 632 can automatically extend and retract according to the wire-covering pressure, adaptively adjusting the wire-covering pressure to avoid wire breakage or sample damage caused by rigid contact. In addition, the wire-covering pressure can be adjusted by replacing different models of spring 632 and sliding sleeve 631. The overall structure is compact.

[0024] The fixed plate 1 is equipped with an origin switch 7, and the first slider 22 is equipped with a touch plate 221 that abuts against the origin switch 7. The origin switch 7 is connected to a controller 8, which is connected to a servo motor 612. In this embodiment, the controller 8 is set on the servo motor 612. The origin switch 7 and the touch plate can provide a precise initial position for the first slider 22, ensuring that the first slider 22 can automatically return to the origin after each operation, ensuring the consistency of the starting position of each overlay operation and improving the consistency of overlay. The controller 8 can automatically control the start and stop of the servo motor 612. In this embodiment, the controller 8 is set on the servo motor 612.

[0025] The second slider 23 is equipped with a wire guide unit 9. The wire 10 is guided by the wire guide unit 9 and then conveyed to the wire covering head 24. The wire guide unit 9 ensures that the wire 10 is accurately conveyed to the wire covering head 24, solving the problems of wire 10 conveying deviation, looseness, and misalignment. Furthermore, placing the wire guide unit 9 on the second slider 23 shortens the distance between the wire guide unit 9 and the wire covering head 24, reducing the shaking of the wire 10. Specifically, the wire guide unit 9 includes a vertical plate 91, a rotating plate 92, and a wire guide block 93. The vertical plate 91 is fixedly installed on the second slider 23. One end of the rotating plate 92 is rotatably connected to the vertical plate 91, and the wire guide block 93 is located at the other end of the rotating plate 92. Because the rotating plate 92 is rotatably connected to the vertical plate 91, and the wire guide block 93 is located at the other end of the rotating plate 92, the angle and position of the wire guide block 93 can be flexibly adjusted to adapt to different operational needs, effectively protecting the integrity of the wire 10 and preventing wear and breakage. The fixing plate 1 is provided with a groove 12 for mounting the linear guide rail 21 and a number of connecting holes 13 connected to the frame of the winding machine. The groove 12 can position and fix the linear guide rail 21, avoid the wobbling of the linear guide rail 21 during operation, and ensure the stability of the movement of the first slider 22 and the second slider 23. Secondly, the connecting holes 13 can realize the quick connection of the entire winding machine covering device to the frame of the winding machine, reducing the overall installation difficulty.

The connecting plate 32 includes a horizontal section 35 and a vertical section 36. The horizontal section 35 is located at the bottom end of the vertical section 36. The piston rod of the cylinder 31 is connected to the vertical section 36. One end of the connecting block 33 is fixedly mounted on the horizontal section 35. The other end of the connecting block 33 has two upwardly protruding protrusions 37. The heating wire 34 is located between the two protrusions 37, thus cutting the section. 3 is configured with a cylinder 31, a connecting plate 32, a connecting block 33, and a heating wire 34. The heating wire 34 can ensure the flatness of the cut and prevent deformation or fraying at the end of the wire 10, thus improving the aesthetics and connection reliability of the wire end. The cylinder 31 enables automated cutting of the heating wire 34 with fast response and stable operation, improving cutting efficiency. The connecting plate 32 and the connecting block 33 make the whole structure more compact and easy to install. The protrusion 37 ensures the stability of the heating wire 34 during installation.

The Z-axis connecting rod 53 is provided with a Z-axis sliding sleeve 63156 for mounting the Y-axis connecting rod 52, and the Y-axis connecting rod 52 is provided with a Y-axis sliding sleeve 63157 for mounting the X-axis connecting rod 51. The fixing block 54 is detachably mounted on the X-axis connecting rod 51, and the fixing block 54 is provided with a fixing ring 58 for mounting the heating rod 55, enabling the heating rod 55 to move in the X-axis direction. The position of the heating rod 55 is adjustable in the Y-axis and Z-axis directions, so that it can be accurately aligned with the sample surface and adapt to the heating requirements of different shapes and sizes. Secondly, the fixing block 54 and the X-axis connecting rod 51 are set as a detachable installation structure, which facilitates the maintenance and replacement of the heating rod 55.
