Description

Technical Field

[0001] The invention relates to the technical field of coil winding, in particular to an automatic winding device and method for an inductor coil. Background Art

[0002] An inductor is a device that works on the principle of electromagnetic induction. When current flows through a wire, a certain electromagnetic field is generated around the wire, and the wire itself in this electromagnetic field will have an inductive effect on the wires within the range of this electromagnetic field. The effect on the wire itself that generates the electromagnetic field is called "self-inductance", that is, the changing current generated by the wire itself produces a changing magnetic field, and this magnetic field further affects the current in the wire. The effect on other wires within the range of this electromagnetic field is called "mutual inductance".

[0003] When winding the insulating ring, the wire is evenly wound on the insulating ring by driving the insulating ring to rotate. However, due to the different diameters of the insulating rings, when winding the insulating ring with a larger diameter, the spacing between the windings is likely to be larger, thereby affecting the production effect. If the diameter is smaller, it will cause extrusion between the wires. At this time, the single rotation angle of the insulating ring needs to be adjusted separately, which is not only cumbersome to operate, but also reduces the scope of application of the equipment.

[0014] The present invention also discloses an automatic winding method for an inductor coil, which uses the automatic winding device for an inductor coil, and comprises the following steps: S1: First, place the insulating ring on one side of the guide wheel, and support the bottom of the insulating ring through the guide wheel; S2: The insulating ring is clamped and fixed by operating the clamping connector. During this process, the pitch-adjusting rotating member drives the guide wheel to change its rotation angle according to the diameter of the insulating ring. S3: Then, the wire is wound around the insulating ring through the operation of the driving motor, the arc bracket, and the rotating ring; S4: Start the pitch-adjusting rotating member, and the operation of the pitch-adjusting rotating member causes the guide wheel to rotate. The larger the diameter of the insulating ring, the smaller the angle at which the pitch-adjusting rotating member drives the guide wheel to rotate. Similarly, the smaller the diameter of the insulating ring, the larger the rotation angle of the guide wheel. The guide wheel drives the insulating ring to rotate intermittently during winding, so that the wire is evenly wound on the insulating ring.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a clamping connector, the guide wheel is pushed toward the support frame, and the aqueous solution inside the water storage tank will enter the first piston cylinder through the extraction of the second piston rod. Then, the coil is placed on one side of the guide wheel, and the guide wheel is released. At this time, the telescopic spring will push the second connecting block to recover, so that the guide wheel connected to the support frame can clamp and limit the insulating ring from different directions. Then, the push rod is pushed to make the blocking block block the aqueous solution inside the first piston cylinder, thereby limiting the guide wheel, so that the insulating rings of different diameters are at the same position after being fixed. In this way, the effect of clamping and limiting the insulating rings of different diameters can be achieved, which increases the scope of application of the equipment; 2. By setting a distance-adjusting rotating member, when the second piston rod moves downward with the first connecting block, the third piston rod drives the bayonet pin to move horizontally on the inner side of the straight groove guide rail, so that the distance between the bayonet pin and the center of the second shift spur gear can be adjusted, and the rotating motor is started. The bayonet pin drives the straight groove guide rail to move up and down reciprocatingly through the operation of the rotating motor, so that the hexagonal connecting rod rotates unidirectionally, so that the second transmission bevel gear drives the first transmission bevel gear to rotate, and thus the transmission shaft drives the guide wheel to rotate. Since the distance between the bayonet pin and the center of the second shift spur gear changes with the movement of the guide wheel, the moving distance of the movable rack can be changed, so that the larger the diameter of the insulating ring, the shorter the distance between the bayonet pin and the center of the second shift spur gear, so that the angle at which the guide wheel drives the insulating ring to rotate at a single time is smaller, thereby improving the uniformity of the wire winding on the surface of the insulating ring.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0020] See also Figures 1 to 9 In an embodiment of the present invention, an automatic winding device for an inductor coil includes an operating table 1, a driving motor 2, an arc bracket 3, and a rotating ring 4. The driving motor 2 is installed on the top of the operating table 1, and the arc bracket 3 located on one side of the driving motor 2 is installed on the top of the operating table 1. One end of the arc bracket 3 is connected to the rotating ring 4 connected to the driving motor 2 through a synchronous wheel and a synchronous belt. A support frame 5 located around the arc bracket 3 is installed on the top of the operating table 1. The number of support frames 5 is set to three, and the three support frames 5 are equidistantly distributed around the notch of the arc bracket 3. A side connecting plate 8 is connected to the support frame 5 located on the side of the arc bracket 3 away from the driving motor 2, and a clamping connector is provided on the support frame 5. The support frame 5 is connected to a guide wheel 12 through the clamping connector, and a pitch-adjusting rotating member located on the inner side of the side connecting plate 8 is installed at the bottom of the support frame 5.

[0021] In this embodiment: when winding the insulating ring, the insulating ring is first placed on one side of the guide wheel 12. At this time, the bottom of the insulating ring is supported by the guide wheel 12, and then the insulating ring is clamped and fixed by operating the clamping connector. During this process, the pitch-adjusting rotating member will drive the guide wheel 12 to change its rotation angle with the diameter of the insulating ring. Then, the wire is wound around the insulating ring by the operation of the driving motor 2, the arc-shaped bracket 3, and the rotating ring 4. During this process, the pitch-adjusting rotating member is started, and the guide wheel 12 drives the insulating ring to rotate through the operation of the pitch-adjusting rotating member. The larger the diameter of the insulating ring, the smaller the angle at which the pitch-adjusting rotating member drives the guide wheel 12 to rotate. Similarly, the smaller the diameter of the insulating ring, the larger the rotation angle of the guide wheel 12. The wire is evenly wound around the insulating ring by the intermittent rotation of the insulating ring driven by the guide wheel 12 during winding.

[0022] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5The clamping connector includes a guide rod 16 movably connected to the top of the support frame 5, a second connecting block 32 is installed at one end of the guide rod 16 away from the support frame 5, the guide wheel 12 is rotatably connected to the top of the second connecting block 32, and telescopic springs 17 connected to the support frame 5 and located on the outside of the guide rod 16 are arranged on both sides of the second connecting block 32. The side of the second connecting block 32 close to the support frame 5 is rotatably connected to the oblique pressure connecting rod 29 through a rotating shaft, and the bottom end of the oblique pressure connecting rod 29 is rotatably connected to the first connecting block 30 through a rotating shaft. A V-shaped connecting rod 6 is installed at the bottom of the first connecting block 30, a water storage tank 11 is installed on the top of the side connecting plate 8, a transition tank 10 is installed at the bottom of the water storage tank 11, a push rod 15 extending to the outside of the transition tank 10 is inserted into the interior of the transition tank 10, and a baffle block 33 movably connected to the inner side of the transition tank 10 is installed at one end of the push rod 15, a first piston cylinder 9 is installed at the bottom of the transition tank 10, a second piston rod 31 is inserted into the inner side of the first piston cylinder 9, and the bottom of the second piston rod 31 is connected to the first connecting block 30.

[0023] In this embodiment: the push rod 15 is pulled to move the baffle block 33 out from between the water storage tank 11 and the first piston cylinder 9, and then the guide wheel 12 is pushed toward the support frame 5. At this time, the second connecting block 32 squeezes and contracts the telescopic spring 17. At the same time, the second connecting block 32 causes the first connecting block 30 to drive the second piston rod 31 to move downward through the oblique pressure connecting rod 29. At this time, the aqueous solution inside the water storage tank 11 will be drawn into the first piston cylinder 9 through the second piston rod 31. Then, the coil is placed on one side of the guide wheel 12, and the guide wheel 12 is released. At this time, the telescopic spring 17 is compressed and contracted. The spring 17 will push the second connecting block 32 to restore, so that the guide wheel 12 connected to the support frame 5 can clamp and limit the insulating ring from different directions, and then push the push rod 15 to move the baffle block 33 to between the water storage tank 11 and the first piston cylinder 9. In this way, the aqueous solution inside the first piston cylinder 9 can lose its flow space, thereby limiting the guide wheel 12, so that the insulating rings of different diameters are at the same position at the center of the circle after being fixed. In this way, the effect of clamping and limiting the insulating rings of different diameters can be achieved, thereby increasing the scope of application of the equipment.

[0024] Please refer to Figure 5 The transition chamber 10 is provided with a through hole that penetrates the transition chamber 10 and is located between the water storage chamber 11 and the first piston cylinder 9 , and the diameter of the through hole is smaller than the diameter of the baffle block 33 .

[0025] In this embodiment: by setting this structure, the aqueous solution inside the first piston cylinder 9 loses flow space when the baffle block 33 is moved between the water storage tank 11 and the first piston cylinder 9, so as to fix the second piston rod 31, thereby preventing the guide wheel 12 from moving when the insulating ring is rotating and winding.

[0026] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 The opening of the V-shaped connecting rod 6 faces the rotating ring 4, and the first connecting blocks 30 connected to different support frames 5 are connected through the V-shaped connecting rod 6.

[0027] In this embodiment: by setting this structure, the synchronous movement of the guide wheels 12 connected to different support frames 5 is achieved.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Fig. 9The pitch-adjusting rotating member includes a connecting frame 7 installed at the bottom of the support frame 5 and located on the inner side of the side connecting plate 8. A rotating motor 13 is installed on the side of the connecting frame 7 away from the arc-shaped bracket 3. The output end of the rotating motor 13 is connected to a first shifting spur gear 23. A second piston cylinder 14 located below the first piston cylinder 9 is arranged on the inner side of the connecting frame 7. A first piston rod 28 extending to the inner side of the second piston cylinder 14 is arranged at the bottom end of the second piston rod 31.

The second guide tube 26 is close to the second piston cylinder 1 A second shifting spur gear 25 meshing with the first shifting spur gear 23 is installed at one end of the guide wheel 12, a third piston cylinder 27 is connected to one end of the second guide pipe 26, a third piston rod 35 extending to the outside of the third piston cylinder 27 is inserted in the third piston cylinder 27, a bayonet 38 is installed at one end of the third piston rod 35 away from the third piston cylinder 27, a straight groove guide rail 40 is sleeved on the bayonet 38, a limit column 34 slidably connected to the connecting frame 7 is installed on the top of the straight groove guide rail 40, a transmission shaft 18 passing through the second connecting block 32 is provided at the bottom of the guide wheel 12, and a first transmission cone 36 is installed at the bottom of the transmission shaft 18 Gear 20, the side of the connecting frame 7 away from the rotating motor 13 is rotatably connected to the hexagonal connecting rod 19 through a bearing, the hexagonal connecting rod 19 is movably sleeved with a second transmission bevel gear 21, the second transmission bevel gear 21 is provided with an L-shaped connecting plate 22 connected to the transmission shaft 18, the transmission shaft 18 and the L-shaped connecting plate 22 are rotatably connected through a bearing, the hexagonal connecting rod 19 is provided with a first ratchet 37 located on one side of the second transmission bevel gear 21, one end of the hexagonal connecting rod 19 is rotatably connected to a rotating coupling 45, and the end of the rotating coupling 45 away from the hexagonal connecting rod 19 is connected to a transmission spur gear 42, and one side of the straight groove guide rail 40 is provided A movable rack 39 is provided which meshes with the transmission spur gear 42, a second ratchet 43 located on one side of the transmission spur gear 42 is fixed on the rotating coupling 45, a support plate 44 is installed on the outer wall of one end of the hexagonal connecting rod 19, the top of the support plate 44 is rotatably connected to a second pawl 41 which meshes with the second ratchet 43 through a rotating shaft, a torsion spring 46 is clamped between the second pawl 41 and the support plate 44 through a slot, a first pawl 36 which meshes with the first ratchet 37 is provided on the side of the connecting frame 7 away from the rotating motor 13, and a torsion spring 46 is also clamped between the first pawl 36 and the connecting frame 7 through a slot.

[0029] In this embodiment: when the second piston rod 31 moves downward with the first connecting block 30, the first piston rod 28 will push the aqueous solution inside the second piston cylinder 14 to flow, so that the aqueous solution inside the second piston cylinder 14 enters the third piston cylinder 27 through the first guide tube 24 and the second guide tube 26. At this time, the third piston rod 35 drives the bayonet 38 to move horizontally on the inner side of the straight groove guide rail 40, so that the distance between the bayonet 38 and the center of the second shifting spur gear 25 can be adjusted. After the guide wheel 12 is fixed, the rotating motor 13 is started. The operation of the rotating motor 13 drives the first shifting spur gear 23 to drive the second shifting spur gear 25 to rotate, so that the third piston cylinder 27 rotates with the second shifting spur gear 25. When the third piston cylinder 27 rotates, the straight groove guide rail 40 can be driven to move back and forth up and down through the bayonet 38. When the movable rack When the movable rack 39 moves upward, the transmission spur gear 42 is driven to swing. At this time, the second ratchet 43 rotates relative to the hexagonal connecting rod 19. When the movable rack 39 moves downward, the second pawl 41 limits the second ratchet 43 in one direction. At this time, the second ratchet 43 will drive the hexagonal connecting rod 19 to rotate through the second pawl 41. In this way, the second transmission bevel gear 21 can drive the first transmission bevel gear 20 to rotate, so that the transmission shaft 18 drives the guide wheel 12 to rotate. Since the distance between the pin 38 and the center of the second shifting spur gear 25 changes with the movement of the guide wheel 12, the moving distance of the movable rack 39 can be changed, so that the larger the diameter of the insulating ring, the shorter the distance between the pin 38 and the center of the second shifting spur gear 25. In this way, the angle at which the guide wheel 12 can drive the insulating ring to rotate at a single time is smaller, thereby improving the uniformity of the wire winding on the surface of the insulating ring.

[0030] Please refer to Figure 7 , Figure 8 A through hole matching the hexagonal connecting rod 19 is provided on the inner side of the second transmission bevel gear 21 , and the first transmission bevel gear 20 is meshed with the second transmission bevel gear 21 .

[0031] In this embodiment: by setting this structure, when the guide wheel 12 moves, the transmission shaft 18 drives the second transmission bevel gear 21 and the first transmission bevel gear 20 to move synchronously through the L-shaped connecting plate 22, so that the second transmission bevel gear 21 and the first transmission bevel gear 20 are always in a meshing state.

[0032] Please refer to Figure 8 The directions of the outer ratchet teeth of the second ratchet 43 and the first ratchet 37 are opposite.

[0033] In this embodiment, by providing this structure, the hexagonal connecting rod 19 can only rotate in one direction, so that the hexagonal connecting rod 19 can rotate intermittently when the straight groove guide rail 40 moves up and down reciprocatingly.

[0034] Please refer to Figure 2 , Figure 3 , Figure 6 The second piston cylinder 14 and the third piston cylinder 27 are equal in size, and an annular sealing gasket is provided at the connection between the first flow guide tube 24 and the second flow guide tube 26.

[0035] In this embodiment, this structure is provided to make the moving distances of the first piston rod 28 and the third piston rod 35 equal.

[0036] Please refer to Figure 6 The diameter of the latch 38 is equal to the width of the inner wall of the straight groove guide rail 40 , and the vertical center axis of the straight groove guide rail 40 is aligned with the vertical center axis of the second shifting spur gear 25 .

[0037] In this embodiment, by providing this structure, the latch 38 is made to reciprocate up and down along the straight groove guide rail 40 as the second shifting spur gear 25 rotates, thereby improving the stability of the movement of the movable rack 39.

[0038] In combination with the above-mentioned automatic winding device for an inductor coil, a method for automatic winding of an inductor coil is provided below, which specifically includes the following steps: S1: first place the insulating ring on one side of the guide wheel 12, and then support the bottom of the insulating ring through the guide wheel 12; S2: Pull the push rod 15 to move the baffle block 33 out from between the water storage tank 11 and the first piston cylinder 9, and then push the guide wheel 12 toward the support frame 5. At this time, the second connecting block 32 squeezes and contracts the telescopic spring 17. At the same time, the second connecting block 32 causes the first connecting block 30 to drive the second piston rod 31 to move downward through the oblique pressure connecting rod 29. At this time, the aqueous solution inside the water storage tank 11 will enter the first piston cylinder 9 through the extraction of the second piston rod 31. Then, place the coil on one side of the guide wheel 12, and release the guide wheel 12. At this time, the telescopic spring 17 will push the second connecting block 32 to restore, so that the guide wheel 12 connected to the support frame 5 clamps and limits the insulating ring from different directions, and then pushes the push rod 15 to move the baffle block 33 to between the water storage tank 11 and the first piston cylinder 9 In this way, the aqueous solution inside the first piston cylinder 9 loses flow space, thereby achieving the limitation of the guide wheel 12, so that the insulating rings of different diameters are at the same position after being fixed. In this way, the effect of clamping and limiting the insulating rings of different diameters can be achieved, which increases the scope of application of the equipment. When the second piston rod 31 moves downward with the first connecting block 30, the first piston rod 28 will push the aqueous solution inside the second piston cylinder 14 to flow, so that the aqueous solution inside the second piston cylinder 14 enters the third piston cylinder 27 through the first guide tube 24 and the second guide tube 26. At this time, the third piston rod 35 drives the bayonet 38 to move horizontally on the inner side of the straight groove guide rail 40, so that the distance between the bayonet 38 and the center of the second shifting spur gear 25 can be adjusted; S3: Then, the wire is wound around the insulating ring by driving the motor 2, the arc bracket 3, and the rotating ring 4; S4: Start the rotary motor 13. The operation of the rotary motor 13 causes the first shifting spur gear 23 to drive the second shifting spur gear 25 to rotate, so that the third piston cylinder 27 rotates along with the second shifting spur gear 25. When the third piston cylinder 27 rotates, the straight groove guide rail 40 can be driven to reciprocate up and down through the bayonet 38. When the movable rack 39 moves up, the transmission spur gear 42 is shifted to swing. At this time, the second ratchet 43 rotates relative to the hexagonal connecting rod 19. When the movable rack 39 moves down, the second pawl 41 limits the second ratchet 43 in one direction. At this time, the second ratchet 43 The hexagonal connecting rod 19 will be driven to rotate through the second ratchet 41, so that the second transmission bevel gear 21 can drive the first transmission bevel gear 20 to rotate, so that the transmission shaft 18 can drive the guide wheel 12 to rotate. Since the distance between the pin 38 and the center of the second shift spur gear 25 changes with the movement of the guide wheel 12, the movement distance of the movable rack 39 can be changed, so that the larger the diameter of the insulating ring, the shorter the distance between the pin 38 and the center of the second shift spur gear 25. In this way, the guide wheel 12 can drive the insulating ring to rotate at a single time. The smaller the angle, the uniformity of the wire winding on the surface of the insulating ring is improved, thereby improving the uniformity of the wire winding on the surface of the insulating ring.
