Description

Technical Field

[0001] This invention relates to the field of inductor coil manufacturing technology, and in particular to a winding device for inductor coil manufacturing and processing. Background Technology

[0002] Inductor coils are typically wound on a magnetic core or frame. The current method involves manual winding, which has significant drawbacks: In terms of efficiency, manual operation is required for each turn, which is time-consuming and slow, severely restricting production efficiency; in terms of quality, it is susceptible to human interference, making it difficult to accurately control parameters such as coil winding position, spacing, and tension, resulting in frequent problems such as uneven coil winding, incorrect number of turns, and broken wires, leading to a low product yield; in terms of product consistency, it is difficult to ensure that the inductor coil specifications of each inductor are uniform, resulting in unstable and inconsistent product quality.

[0003] In addition, in the existing method, the wire feeding device makes a circular motion around the magnetic core during winding, which causes an angle between the coil and the surface of the magnetic core. This prevents the coil from being in close contact with the surface of the magnetic core during winding, which makes the wound coil prone to unstable tension. Unstable tension can lead to serious consequences, such as loosening between coil turns, affecting the stability of inductance, and easily causing short circuits between turns in a vibrating environment. Summary of the Invention

[0004] The purpose of this invention is to provide a winding equipment for the production and processing of inductor coils, so as to solve the problems of slow speed and poor efficiency in the winding process, as well as unstable tension and tension differences between layers in multi-layer winding, thereby improving the winding quality and performance of inductor coils.

[0005] The technical solution of the present invention: a winding equipment for producing and processing inductor coils, comprising a roller frame for placing magnetic cores, the roller frame being composed of at least three electrically guided rollers rotating in the same direction;

[0006] A positioning frame is provided between the roller frames. An installation frame and a gear sleeve are slidably installed in the positioning frame. The installation frame and the gear sleeve are fixedly connected. A motor is fixed on the positioning frame. The output end of the motor is fixed with a drive gear that meshes with the gear sleeve. When winding, the installation frame passes through the magnetic core. A wire feeding box is fixedly installed on the installation frame. Several control devices are also installed at equal intervals.

[0007] The control device includes a hydraulic cylinder fixed on a mounting frame, a piston rod inside the cylinder, the piston rod including a baffle, a limit seat fixed to the piston rod, a branch oil passage communicating with the hydraulic cylinder between the piston rod and the limit seat, hydraulic oil inside the cylinder, a secondary piston rod inside the branch oil passage, a push plate hinged to the secondary piston rod, a connecting rod fixed on the piston rod, a hinge spring installed between the push plate and the connecting rod, the hydraulic cylinder including a secondary piston cylinder, a piston head inside the secondary piston cylinder, a side frame fixed on the positioning frame on the inner side of the gear sleeve, several arc-shaped heads evenly distributed inside the side frame, a side push plate fixed on the limit seat, a guide cavity formed between the side push plate and the push plate, a limit roller below the limit seat inside the guide cavity.

[0008] Preferably, the oil cylinder also includes an overflow tank, which is connected to the oil cylinder. An electronic check valve is installed at the connection point. The electronic check valve has a threshold value, and the receiving chamber inside the overflow tank is located above the connection point between the overflow tank and the oil cylinder.

[0009] Preferably, the bottom of both the push plate and the side push plate is arc-shaped, and the bottom of both the push plate and the side push plate is provided with ball bearings.

[0010] Preferably, the wire outlet box includes a wire outlet, and the wire outlet and the guide cavity are located on the same horizontal line.

[0011] Preferably, the roller frame also includes a housing, an electric guide roller is mounted on the housing, a positioning frame is fixed on the housing, a worktable is mounted on the bottom of the housing, an electric slide rail is provided on the worktable, a cover seat and a cutting blade are provided on the electric slide rail, and a sleeve for receiving the electric guide roller is mounted on the cover seat.

[0012] Preferably, the positioning frame has an inlet and outlet, and a plug can be detachably installed at the inlet and outlet. The mounting frame, gear sleeve and side frame have notches, and mating parts are installed at the notches. The mating parts include a mounting frame head that is adapted to the mounting frame, a gear sleeve head that is adapted to the gear sleeve and a side frame head that is adapted to the side frame.

[0013] Compared with existing technologies, the beneficial effects of the present invention are as follows: By installing a control device in the mounting frame and ensuring that the coil is located in the guide cavity during operation, the present invention can ensure that the coil is always in contact with the surface of the magnetic core during winding, so that the included angle between the coil and the magnetic core disappears, ensuring the stability of the tension. In addition, the present invention can push the coil during winding, which improves the coil arrangement accuracy and uniformity. Furthermore, by using the same pushing force, the coil can ensure that the inter-turn spacing is the same in real time, preventing loosening, overlapping, or uneven density caused by tension fluctuations or changes in winding speed, and ensuring that the coil is tightly and neatly arranged.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] See attached document Figure 1-8 A winding device for producing and processing inductor coils includes a roller frame for placing magnetic cores, the roller frame being composed of at least three electrically guided rollers 200 rotating in the same direction;

[0025] A positioning frame 1 is provided between the roller frames. A mounting frame 2 and a gear sleeve 3 are slidably installed inside the positioning frame 1. The mounting frame 2 and the gear sleeve 3 are fixedly connected. A motor 4 is fixed on the positioning frame 1. A drive gear 5 that meshes with the gear sleeve 3 is fixed at the output end of the motor 4. When winding, the mounting frame 2 passes through the magnetic core. A wire feeding box 6 is fixedly installed on the mounting frame 2. Several control devices 7 are also installed at equal intervals.

[0026] The control device 7 includes a hydraulic cylinder 71 fixed on the mounting frame 2. A piston rod 72 is provided inside the hydraulic cylinder 71. The piston rod 72 includes a baffle 73. A limit seat 79 is fixed to the piston rod 72. A branch oil passage 721 communicating with the hydraulic cylinder 71 is opened between the piston rod 72 and the limit seat 79. Hydraulic oil is provided inside the hydraulic cylinder 71. A secondary piston rod 8 is provided inside the branch oil passage 721. A push plate 9 is hinged to the secondary piston rod 8. A connecting rod 11 is fixed to the piston rod 72. A hinge spring 12 is installed between 9 and connecting rod 11. The oil cylinder 71 includes a secondary piston cylinder 74, and a piston head 75 is provided inside the secondary piston cylinder 74. A side frame 781 fixed on the positioning frame 1 is provided on the inner side of the gear sleeve 3. Several arc-shaped heads 78 are evenly distributed inside the side frame 781. A side push plate 10 is fixed on the limiting seat 79. A guide cavity 600 is formed between the side push plate 10 and the push plate 9. A limiting roller 13 is provided below the limiting seat 79 inside the guide cavity 600.

[0027] The existing manual winding method is slow, which severely restricts production efficiency. In terms of quality, it is easily affected by human factors, and it is difficult to accurately control parameters such as coil winding position, spacing and tension. This leads to frequent problems such as uneven coil winding, incorrect number of turns, and wire breakage, resulting in a low product yield.

[0028] This invention involves mounting a magnetic core on a roller frame. In this embodiment, the magnetic core is supported by three electrically guided rollers 200. The rotation of these rollers drives the magnetic core to rotate. During winding, the magnetic core passes through the mounting frame 2. The starting motor 4 drives the gear sleeve 3 to rotate via the drive gear 5. This gear sleeve 3 then drives the mounting frame 2 to rotate, allowing the pay-off box 6 on the mounting frame 2 to rotate around the magnetic core. Once one end of the coil in the pay-off box 6 is fixed to the magnetic core, the coil winding operation can be performed by rotating the pay-off box 6 around the magnetic core. As the magnetic core rotates continuously, the entire circumference of the magnetic core is wound, thus achieving mechanical winding and greatly improving work efficiency.

[0029] like Figure 7 As shown, Figure 7 This diagram illustrates the positional changes of the coil relative to the surface of the magnetic core as the pay-off box 6 moves during the winding process of the existing magnetic core. In the diagram, A represents the magnetic core, B represents the coil, C represents the direction of movement of the pay-off box 6, and 6' represents the position of the pay-off box 6 at different stages of its movement. Figure 7 As can be seen, as the wire box 6 moves, there is always an angle between the coil and the surface of the magnetic core. The presence of the angle makes it impossible for the coil to stick to the surface of the magnetic core. Therefore, the coil will have unstable tension during winding, which will easily cause slack between the coil turns.

[0030] like Figure 8 As shown, Figure 8 Is Figure 7 The working effect after adding control device 7 to the basic structure. Figure 8 The tags and Figure 7 In accordance with the principle that when several control devices 7 are installed at equal intervals around the perimeter of the mounting frame 2, from Figure 8 It can be seen that the coil is pressed by the control device 7. Therefore, in this way, the angle between the coil and the surface of the magnetic core disappears, so that the coil will move along the surface of the magnetic core, ensuring the stability of the tension during winding.

[0031] In specific tasks, such as Figure 4 and Figure 5 As shown, during winding, after one end of the coil is fixed, the coil passes through the guide cavity 600 formed between the side push plate 10 and the push plate 9. The coil is located below the limiting roller 13. During the winding process, the hydraulic oil through the oil cylinder 71 will continuously act downward on the piston rod 72, causing the piston rod 72 to press down on the limiting seat 79, thus ensuring that the coil is always in contact with the surface of the magnetic core.

[0032] Furthermore, when the mounting frame 2 rotates, it will drive the control device 7 to rotate. When the control device 7 rotates, the piston head 75 will contact several arc-shaped heads 78. The arc-shaped heads 78 will push the piston head 75 to move into the oil cylinder 71. At this time, the hydraulic oil in the oil cylinder 71 will act downward to form pressure. Because of the presence of the baffle 73, the piston rod 72 will not move downward. At this time, the hydraulic oil will enter the branch oil passage 721, so that the pressure will push the auxiliary piston rod 8 out. The auxiliary piston rod 8 will push the push plate 9, so that the push plate 9 will rotate slightly with the hinge spring 12 as the fulcrum. Because the push plate 9 is set in an inclined position, the bottom of the push plate 9 rotates to a large extent.

[0033] observe Figure 5 As shown, the guide cavity 600 contains the coil to be wound, and the push plate 9 contains the coil wound on the magnetic core. By rotating the bottom of the push plate 9, the push plate 9 will push the wound coil, which improves the coil arrangement accuracy and uniformity. Furthermore, by using the same pushing force, the coil can ensure that the turn spacing is the same in real time, preventing loosening, overlapping, or uneven density caused by tension fluctuations or changes in winding speed, and ensuring that the coil is tightly and neatly arranged.

[0034] Preferably, the oil cylinder 71 further includes an overflow tank 76, which is connected to the oil cylinder 71. An electronic check valve 77 is installed at the connection point. The electronic check valve 77 has a threshold value. The receiving cavity in the overflow tank 76 is located above the connection point between the overflow tank 76 and the oil cylinder 71. The bottoms of the push plate 9 and the side push plate 10 are both arc-shaped. The bottoms of the push plate 9 and the side push plate 10 are both provided with ball bearings 14. The wire feeding box 6 includes a wire outlet 500, which is located on the same horizontal line as the guide cavity 600.

[0035] When the control device 7 moves to the thickness of the magnetic core, the distance between the mounting frame 2 and the magnetic core decreases. Therefore, when the push plate 9 and the side push plate 10 contact the magnetic core, they will push the piston rod 72 into the oil cylinder 71. When the pressure in the oil cylinder 71 reaches the threshold of the electronic check valve 77, the electronic check valve 77 will open, allowing hydraulic oil to enter the overflow tank 76. In this way, the piston rod 72 can move into the oil cylinder 71, ensuring that the control device 7 can pass through the thickness of the magnetic core normally.

[0036] In addition, the bottom of the push plate 9 and the side push plate 10 are designed with an arc shape and are equipped with ball bearings 14, which can prevent them from getting stuck, reduce friction, and ensure normal passage.

[0037] In this embodiment, the roller frame also includes a housing 100, an electric guide roller 200 mounted on the housing 100, a positioning frame 1 fixed on the housing 100, a workbench mounted on the bottom of the housing 100, an electric slide rail 800 mounted on the workbench, a cover seat 700 and a cutting blade 900 mounted on the electric slide rail 800, a sleeve for receiving the electric guide roller 200 mounted on the cover seat 700, an inlet and outlet 300 mounted on the positioning frame 1, a plug 400 detachably mounted at the inlet and outlet 300, a notch mounted on the mounting frame 2, a gear sleeve 3 and a side frame 781, a mating part 1000 mounted on the notch, the mating part 1000 including a mounting frame head adapted to the mounting frame 2, a gear sleeve head adapted to the gear sleeve 3 and a side frame head adapted to the side frame 781 respectively.

[0038] It should be noted that the setting of the 300 for the inlet / outlet and the 400 for the plug does not affect normal use.

[0039] In the specific operation, the cover 700 is moved away from the positioning frame 1 by the electric slide rail 800. Then the plug 400 is removed, and the mounting frame head, gear sleeve head and side frame head are also removed. Then the mounting frame 2, gear sleeve 3 and side frame 781 have notches, which face the inlet and outlet 300, forming a channel for the magnetic core to pass through. Then the magnetic core is passed through the positioning frame 1 and placed on the three electric guide rollers 200. Then the cover 700 returns to its position to support the electric guide rollers 200 and ensure the stability of the electric guide rollers 200.

[0040] In addition, the mounting frame head, gear sleeve head and side frame head all have gaps with the mounting frame (2), gear sleeve (3) and side frame (781) for a proper fit, or they can be fixed by bolts.
