Description

Technical Field

[0001] The invention relates to the technical field of winding machines, in particular to an automatic winding machine for a micro transformer coil. Background Art

[0002] In the production process of micro-transformers, the winding process is crucial, and its quality and efficiency directly affect the performance and production benefits of the transformer. However, there are many problems with the traditional winding method of micro-transformers. When fixing the iron core, traditional winding equipment usually uses a single-specification fixture, which is difficult to adapt to micro-transformer iron cores of different sizes and shapes. For square iron cores, due to the differences in the length, thickness and size of the internal hollow part, it is difficult for traditional devices to accurately support and fix the internal side walls. During the winding process, the iron core is prone to shaking and displacement, resulting in uneven winding, which not only affects the quality of the coil, but also may reduce the performance of the micro-transformer and increase the defective rate; when facing cylindrical iron cores, the problem is also prominent. The inner diameter, length and other specifications of different cylindrical iron cores are different. Traditional winding equipment lacks a flexible adaptation mechanism and is difficult to adjust according to the specific size of the iron core. This requires operators to spend time manually adjusting the fixture before winding, or frequently replace different fixing parts, thereby affecting production progress. Summary of the invention

At the same time, these supporting devices have individual adjustment functions and are easy to operate, thereby improving the winding efficiency and quality. The placement device can flexibly adjust the position and angle to facilitate the placement, use and cutting of copper wire rolls. The anti-slip device can also guide the direction of the copper wire and keep it taut to avoid falling off, effectively meeting the needs of micro-transformer coil production.

One end of the vertical linkage rod 337 is positioned by the vertical positioning frame 315, so the rotating cylinder 335 gradually approaching the limit head 314 will push the vertical rotating rod 336 to move, so that the vertical linkage rod 337 moves together, thereby jointly pushing the limit device 8 to move, thereby supporting the internal hollow primary coil core.

[0038] The limiting device 8 includes a double-pass block 81, the outer wall of the bottom of the double-pass block 81 is fixedly connected to a connecting plate 82, the outer wall of the double-pass block 81 is fixedly connected to a buffer plate 83, and the inner wall of the double-pass block 81 is fixedly connected to a limiting rod 84.

The double-pass block 81 is connected through the connecting plate 82 and then moves with the supporting position of the vertical support device 33 and the horizontal support device 34, and the balance of the supporting position is maintained by the oppositely plugged limiting rods 84.

The moving sliding block 341 will drive the rotating tube 343 to slide along the connecting rod 313, and the protruding block 344 will slide in the movable groove 318. Since the transverse linkage rod 346 rotates around the transverse positioning frame 316 under the positioning of the transverse positioning frame 316, the moving transverse rotating rod 345 drives the transverse linkage rod 346 to move, and at the same time pushes the limit device 8 to move, thereby realizing the transverse support and positioning inside the iron core.

[0042] Example 2: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: on the basis of the first embodiment, the placing device 4 includes a sliding seat 41, the inner wall of the sliding seat 41 is threadedly connected to the outer wall of the adjusting screw 6 through a threaded hole 42, the inner wall of the sliding seat 41 is slidably connected to the outer wall of the base 1 through a positioning hole 43, the inner wall of the sliding seat 41 is slidably connected to the outer wall of the base 1 through an avoidance groove 44, the outer wall of the top of the sliding seat 41 is fixedly connected with a supporting plate 45, the inner wall of the supporting plate 45 is rotatably connected with a rotating wheel 46, the outer wall of the rotating wheel 46 is fixedly connected with a driving gear 47, and the outer wall of the supporting plate 45 is rotatably connected with an adjusting device 48, the base 1 provides support for the entire device, and the protective shell 2 plays a protective role, the DC motor 5 is started to drive the adjusting screw 6 to rotate, and the adjusting screw 6 cooperates with the threaded hole 42 on the inner wall of the sliding seat 41 to make the sliding seat 41 slide along the base 1, thereby adjusting the position of the placing device 4, the rotating wheel 46 on the placing device 4 can place the copper wire roll, and the spiral cover 484 can fix the placed copper wire roll.

[0043] The adjusting device 48 includes a rotating ring 481, the outer wall of which is fixedly connected to a driven gear ring 482, the outer wall of which is fixedly connected to a fixed block 483, the inner wall of which is threadedly connected to a screw cover 484, the inner wall of which is fixedly connected to a sliding column 485, the outer wall of which is provided with a limiting groove 486, the outer wall of which is slidably connected to an anti-slip device 487, the driving gear 47 is meshed with the driven gear ring 482, the rotating ring 481 can rotate relative to the support plate 45, thereby adjusting the position of the copper wire roll, and since the position of the copper wire roll can be adjusted, the copper wire can be moved to a position where it is easier to cut after the winding process is completed.

[0044] The outer wall of the sliding seat 41 is slidably connected to the outer wall of the base 1, the inner side wall of the rotating ring 481 is rotatably connected to the outer wall of the support plate 45, the outer wall of the driving gear 47 is meshed with the outer wall of the driven gear ring 482, the anti-slip device 487 includes a sliding ring 4871, the outer wall of the sliding ring 4871 is fixedly connected with a positioning protrusion 4872, the outer wall of the positioning protrusion 4872 is slidably connected to the outer wall of the sliding column 485 through a limiting groove 486, the outer wall of the sliding ring 4871 is symmetrically fixedly connected with a protective ring 4873, and the outer wall of the protective ring 4873 is provided with a guide groove 4874. The anti-slip device 487 can prevent the copper wire roll from falling off. Before winding, the copper wire is moved along the guide groove 4874, so that the protective ring 4873 is slightly deformed and then sent between the protective ring 4873 and the sliding ring 4871, thereby preventing the copper wire from falling off. According to the winding rotation direction, the sliding column 485 is bypassed from top or bottom to tighten the copper wire. At the same time, the positioning protrusion 4872 of the sliding ring 4871 slides in the limit groove 486, and the copper wire is guided by the guide groove 4874 on the protective ring 4873, so that the copper wire is in a tensioned position during winding and is difficult to fall off.

[0045] When in use, the inner support device 3 is fixed by supporting outward, and the servo motor 311 of the rotating device 31 drives the transmission rod 312, the connecting rod 313 and the limit head 314 to rotate, so that the coil rotates to complete the iron core winding of the primary coil of the micro transformer;

[0046] The stepping motor 331 on the mounting frame 32 drives the rotating screw 332 to rotate, so that the internal thread block 333 moves, and then drives the rotating cylinder 335 to drive the vertical rotating rod 336 to rotate. One end of the vertical linkage rod 337 is positioned by the vertical positioning frame 315, so the rotating cylinder 335 gradually approaching the limit head 314 will push the vertical rotating rod 336 to move, so that the vertical linkage rod 337 moves together, thereby jointly pushing the limit device 8 to move, so as to support the hollow primary coil core inside, which is convenient for winding. Due to the drive of the limit frame 317, the rotating cylinder 335 can rotate synchronously with the limit head 314;

[0047] The sliding block 341 of the transverse support device 34 moves with the push of the cylinder 7, and the cylinder 7 can provide auxiliary power when it is fixed. The moving sliding block 341 will drive the rotating tube 343 to slide along the connecting rod 313, and the protruding block 344 will slide in the movable groove 318. Since the transverse linkage rod 346 rotates around the transverse positioning frame 316 under the positioning of the transverse positioning frame 316, the moving transverse rotating rod 345 drives the transverse linkage rod 346 to move, and at the same time pushes the limit device 8 to move, so as to realize the transverse support and positioning inside the iron core. Due to the setting of the movable groove 318, the limit head 314 drives the protruding block 344 to move, thereby making the rotating tube 343 rotate synchronously;

[0048] The limiting device 8 is composed of two parts of the same structure plugged into each other, wherein one side of the double-pass block 81 as the main body cooperates with the buffer plate 83 to fix a limiting rod 84, and the limiting rod 84 is inserted into the double-pass block 81 on the opposite side which is in an idle position. The double-pass block 81 is connected by the connecting plate 82 and moves with the supporting position of the vertical support device 33 and the horizontal support device 34, and the supporting position is balanced by the oppositely plugged limiting rods 84, so that the inner side wall of the iron core is stably fitted, and thus more stable when it is fixed;

[0049] The vertical support device 33 and the lateral support device 34 respectively support the inner side wall of the hollow core, thereby fixing the position of the core, so that it remains stable during winding. Since the hollow core in the primary coil of the micro transformer has a tubular shape in addition to a cylindrical shape, the traditional internal support clamping mechanism is difficult to stably adapt to square cores of different specifications, while the vertical support device 33 and the lateral support device 34 have separate adjustment functions, so that the internal support can be adjusted;

[0050] When the inner support device 3 performs a coiling operation on the cylindrical iron core, the pin can be inserted into the first pin hole 334 and the second pin hole 347, so that the sliding block 341 and the internal thread block 333 move synchronously, thereby maintaining the synchronous expansion of the vertical support device 33 and the horizontal support device 34, and then adapting to the inner support fixation of the cylindrical hollow iron core. The inner support device 3 fixes the position of the coil iron core through the vertical support device 33 and the horizontal support device 34 and drives it to rotate, realizing automatic winding, improving the winding efficiency, and is suitable for the production of micro transformer coils.

[0051] When the micro transformer coil automatic winding machine is working, the base 1 provides support for the entire device, the protective shell 2 plays a protective role, the DC motor 5 starts to drive the adjusting screw 6 to rotate, and the adjusting screw 6 cooperates with the threaded hole 42 on the inner wall of the sliding seat 41 to make the sliding seat 41 slide along the base 1, thereby adjusting the position of the placing device 4, and the rotating wheel 46 on the placing device 4 can place the copper wire roll, and the spiral cover 484 can fix the placed copper wire roll;

[0052] The driving gear 47 is meshed with the driven gear ring 482, and the rotating ring 481 can rotate relative to the support plate 45, so as to adjust the position of the copper wire roll. Since the position of the copper wire roll can be adjusted, the copper wire can be moved to a position where it is easier to cut after the winding process is completed, which is convenient for the staff to use and wind the wire;

[0053] The anti-slip device 487 can prevent the copper wire roll from falling off. Before winding, the copper wire is moved along the guide groove 4874, so that the protective ring 4873 is slightly deformed and then sent between the protective ring 4873 and the sliding ring 4871, thereby preventing the copper wire from falling off. According to the winding rotation direction, the sliding column 485 is bypassed from top to bottom to make the copper wire tensioned. At the same time, the positioning protrusion 4872 of the sliding ring 4871 slides in the limit groove 486, and the guide groove 4874 on the protective ring 4873 guides the direction of the copper wire, so that the copper wire is in a tensioned position during winding and is difficult to fall off; the placement device 4 can flexibly adjust the position and angle, which is convenient for placing and using the copper wire roll and can prevent the copper wire roll from falling off.
