Description

Technical Field

[0001] This invention relates to the field of forming mechanism technology, and in particular to a flat wire coil forming mechanism. Background Technology

[0002] In the field of motor manufacturing, flat wire windings have become a core technology for high-performance motors because they can effectively improve the slot fill factor and power density.

[0003] However, the current flat wire coil forming process still faces many technical bottlenecks, such as the difficulty of winding, insufficient forming precision, the high rigidity of flat wire itself, and the rectangular cross-section. Traditional winding mechanisms have difficulty in accurately controlling the bending angle and size, which can easily lead to problems such as flat wire twisting and irregular winding shape. This directly affects the performance stability and service life of the motor. Moreover, most flat wire winding equipment requires manual assistance to complete processes such as wire feeding, positioning, clamping and adjustment. The poor connection between each link not only leads to low production efficiency, but also large human operation errors, making it difficult to meet the needs of large-scale and high-precision production.

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] This invention provides, for example Figures 1-7The flat wire coil forming mechanism shown includes a mounting plate 1, a forming component 2, a forming clamping component 3, a conveying component 4, a feeding clamping component 5, and a tensioning component 6. The forming component 2 is mounted on the mounting plate 1 and is used to bend and form the flat wire. The forming clamping component 3 is mounted on the top of the mounting plate 1 and is used to clamp and position the flat wire when the forming component 2 bends it. The conveying component 4 and the feeding clamping component 5 are mounted on the mounting plate 1 and work together to quantitatively convey the flat wire. The tensioning component 6 is located on one side of the mounting plate 1. That is, when bending and forming the flat wire, the flat copper wire enters from the rear side of the tensioning component 6 and then passes through the conveying component 4. When the feeding clamping assembly 5 reaches the forming assembly 2, and the conveying assembly 4 and the feeding clamping assembly 5 are conveying the flat wire, the forming clamping assembly 3 is in a released state. When winding is required, the forming clamping assembly 3 clamps the copper wire, the feeding clamping assembly 5 releases the copper wire, and the conveying assembly 4 and the feeding clamping assembly 5 return to the starting wire feeding position. Then the forming assembly 2 begins forming and bending. After bending, the forming clamping assembly 3 is released, and the conveying assembly 4 and the feeding clamping assembly 5 convey the flat wire again. This reciprocating action is repeated for each coil until the entire coil is wound. After one coil is wound, the conveying assembly 4 and the feeding clamping assembly 5 convey a certain length of flat wire, so that adjacent flat wires are staggered in a stepped manner. Figure 1 The coil in the diagram is shown.

[0062] Furthermore, the forming component 2 includes a first fixing frame 21, a first mounting base 24, a bending head 26, a second fixing frame 22, a first servo motor 23, and a second mounting base 25. The first fixing frame 21 is fixedly mounted on the mounting plate 1, and the first mounting base 24 is fixedly mounted on the first fixing frame 21. The bending head 26 is disposed on the top of the first mounting base 24 and is used to bend the flat wire. The first servo motor 23 is mounted on the bottom of the first fixing frame 21 through the second fixing frame 22. The second mounting base 25 is rotatably connected to the top of the first mounting base 24, and the bending head 26 is connected to the top of the second mounting base 25. The output end of the first servo motor 23 is connected to the second mounting base 25 for transmission. The first servo motor 23 can drive the bending head 26 to rotate through the second mounting base 25, thereby causing the bending head 26 to bend the flat wire.

[0063] Specifically, the bending head 26 includes a connecting seat 261, a fixing plate 262, a bending member 263, and a bending post 265. The connecting seat 261 is fixedly installed on the top of the second mounting seat 25. The fixing plate 262 is fixedly connected to the top of the connecting seat 261. The bending member 263 is fixedly connected to the top of the fixing plate 262. A first protrusion 264 for limiting the flat line is fixedly connected to the side of the bending member 263. The bending post 265 is fixedly connected to the top of the connecting seat 261 through the fixing plate 262. The bending post 265 is located on the top of the bending member 263. A second protrusion 266 for layering the bending flat line is fixedly connected to the top of the bending post 265. Figure 3 As shown, when the flat wire is located between the bending member 263 and the bending post 265, the first servo motor 23 drives the connecting seat 261 to rotate around the bending post 265 via the second mounting base 25, thereby causing the bending member 263 to bend the flat wire along the outer wall of the bending post 265. Under the action of the first protrusion 264 and the second protrusion 266, the coil can be layered vertically to bend into a coil. The connecting seat 261 can be adjusted in position on the second mounting base 25, so that the bending member 263 can work with the bending post 265 at different positions. The two bending posts 265 have different diameters, and the inner diameter of the bent coil is also different.

[0064] Furthermore, the forming clamping assembly 3 includes a third fixing frame 31, a wire outlet 32, a first pressure plate 33, a fourth fixing frame 34, a first drive cylinder 35, and a second pressure plate 36. The third fixing frame 31 is fixedly connected to the top of the mounting plate 1, and the wire outlet 32 ​​is fixedly connected to the top of the third fixing frame 31. The wire outlet 32 ​​is used to guide and convey the flat wire, thereby improving the stability of the flat wire conveyed to the forming assembly 2. The first pressure plate 33 is fixedly connected to the top of the third fixing frame 31, and the top of the first pressure plate 33 has an opening. There is a cable tray corresponding to the cable outlet 32. The fourth fixing bracket 34 is fixedly installed on the top of the third fixing bracket 31. The first driving cylinder 35 is installed inside the fourth fixing bracket 34. The second pressure plate 36 is drivenly connected to the output end of the first driving cylinder 35. The second pressure plate 36 and the first pressure plate 33 cooperate to press and position the flat wire. That is, under the action of the first driving cylinder 35, the second pressure plate 36 and the first pressure plate 33 can press and bind the flat wire, thereby ensuring the stability of the forming component 2 when bending the flat wire.

[0065] Furthermore, the conveying assembly 4 includes a first bearing plate 41, a bearing platform 42, a slide rail 43, a slide block 44, a second servo motor 45, a drive screw 46, a photoelectric sensor 47, and a sensing plate 48. The first bearing plate 41 is fixedly connected to the top of the mounting plate 1. The bearing platform 42 is slidably mounted on the top of the first bearing plate 41 via the slide rail 43 and the slide block 44. That is, the slide rail 43 is fixedly connected to the top of the first bearing plate 41, and the slide block 44 is slidably sleeved on the outside of the slide rail 43 and fixedly mounted on the bottom of the bearing platform 42. The feeding clamping assembly 5 is mounted on the top of the bearing platform 42. When the feeding clamping assembly 5 clamps the flat wire, the bearing platform 42 moves to convey the flat wire, and when the feeding clamping assembly 5 releases the flat wire, the bearing platform 42... 2. The device can be moved and reset. The second servo motor 45 is installed on one side of the first support plate 41, and the drive screw 46 is rotatably installed on the top of the first support plate 41. The output end of the second servo motor 45 is connected to the drive screw 46. The bottom of the support platform 42 is fixedly connected to a threaded sleeve that is threadedly connected to the drive screw 46. Thus, the second servo motor 45 drives the drive screw 46 to rotate, which can drive the support platform 42 to slide on the top of the first support plate 41. The photoelectric sensor 47 is fixedly installed on the side of the first support plate 41, and the sensing plate 48 is fixedly installed on the side of the support platform 42. The sensing plate 48 and the photoelectric sensor 47 are used to detect the distance of movement of the support platform 42 to improve the accuracy of flat wire length conveying.

[0066] Furthermore, the feeding clamping assembly 5 includes a second bearing plate 51, a third pressure plate 52, a fifth fixing frame 53, a second cylinder 54, and a fourth pressure plate 55. The second bearing plate 51 is fixedly connected to the top of the bearing platform 42, the third pressure plate 52 is fixedly connected to the top of the second bearing plate 51, the second cylinder 54 is fixedly installed on the top of the second bearing plate 51 through the fifth fixing frame 53, and the fourth pressure plate 55 is drivenly connected to the output end of the second cylinder 54. The fourth pressure plate 55 and the third pressure plate 52 are used to clamp and limit the flat wire, that is, the second cylinder 54 drives the fourth pressure plate 55 to move up and down, so that the fourth pressure plate 55 and the third pressure plate 52 can clamp or release the flat wire.

[0067] Specifically, the tensioning assembly 6 includes an arm plate 61, an assembly base 62, a first guide roller 63, and a second guide roller 64. The arm plate 61 is fixedly connected to the top of the mounting plate 1, and the assembly base 62 is fixedly installed at the end of the arm plate 61. The first guide rollers 63 are rotatably mounted side-by-side on the front of the assembly base 62, with the first guide rollers 63 located at the top of the flat wire. The second guide rollers 64 are rotatably mounted side-by-side on the front of the assembly base 62, with the second guide rollers 64 located at the bottom of the flat wire. The second guide rollers 64 and the first guide rollers 63 are staggered. Under the action of multiple second guide rollers 64 and multiple first guide rollers 63, not only can the accuracy of the flat wire entry position be improved, but also the tension of the flat wire can be improved.
