Description

Technical Field

[0001] The invention relates to the technical field of coil winding, and in particular to a high-efficiency winding system for winding multiple coils. Background Art

[0002] A coil usually refers to a ring-shaped wire winding. The most common coil applications are: motors, inductors, transformers and loop antennas.

[0003] A multiple coil is a motor coil having multiple coil frames connected by a wire, and each coil frame is wound with a wire. After winding, the multiple coil frames need to be spliced ​​together and the wires need to be bent. Therefore, the wire length between two adjacent coil frames is very high. If the wire is too long, it will extend out of the two coil frames after splicing, and if it is too short, it will make it difficult to splice the two coil frames. Most of the winding systems in the prior art fix the two coil frames in the same fixture and then wind them. For example, a winding system for a motor coil disclosed in patent number CN201822238531.0, the winding device 40 of the winding system of the motor coil includes a rotating table 41, a fixture 42 disposed on the rotating table 41, and a wire clamp 43 disposed on the rotating table 41, and a release mechanism 44 disposed on the rotating table 41. The rotating table 41 can rotate under the control of the motor to allow the wire to be wound around the magnetic core located on the fixture 42, and the fixture 42 is used to fix the two magnetic cores. However, when the coil skeletons have different specifications, i.e., different lengths, the distance between the two coil skeleton jigs needs to be adjusted. However, it is not convenient to adjust the wire distance when the two coil skeletons are set on the same jig, and multiple different jigs need to be prepared, which makes the cost very high. In addition, since the two coil skeletons need to be wound with the same wire, it is not convenient to rotate the wire when the two coil skeletons are set on the same jig. Summary of the invention

[0019] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0020] like Figures 1 to 6 As shown, it is a schematic diagram of the structure of the efficient winding system for winding multiple coils provided by the present invention. The efficient winding system for winding multiple coils includes a machine 10, a wire passing mechanism 20 arranged on the machine 10, a plurality of winding mechanisms 30 arranged on the machine 10, and a loading and unloading mechanism 40 arranged on the machine 10. It can be imagined that the efficient winding system for winding multiple coils also includes some other functional modules, such as a tension component, a wire cutting component, etc., which are well known to those skilled in the art and will not be repeated here.

[0021] First of all, it should be noted that the high-efficiency winding system for winding multiple coils is used to wind multiple coils, and the multiple coils include at least two coil frames 100 and a wire wound on the coil frames 100. The coil frames 100 should be prior art and will not be described in detail.

[0022] The machine 10 is used to carry the above-mentioned functional modules, so the machine 10 is provided with a variety of functional structures, such as screws, bolts, clamps, etc. to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs and will not be described in detail one by one here.

[0023] The wire-passing mechanism 20 includes a first three-axis moving device 21 disposed on the machine platform 10 , and a plurality of guide needle assemblies 22 disposed on the first three-axis moving device 21 .

[0024] The first three-axis moving device 21 drives the plurality of guide needle assemblies 22 to move in three axes to adjust the positions of the guide needles and the guide wires, which should be the prior art and will not be described in detail here. In this embodiment, the high-efficiency winding system for winding multiple coils can wind six coils at the same time, so the guide needle assemblies 22 are provided with six in this embodiment, and the number can be set according to actual needs.

[0025] The guide needle assembly 22 includes a wire passing plate 221 , a wire withdrawal clamp 222 arranged on the first three-axis moving device 21 , a wire guide plate 223 arranged on the first three-axis moving device 21 , and a guide needle 224 arranged on the wire guide plate 223 .

[0026] The wire plate 221 is provided with a wire eyelet for passing the wire, and the wire withdrawal clamp 222 is located between the wire plate 221 and the wire plate 223. The wire withdrawal clamp 222 is used to clamp the wire when not winding the wire to prevent the wire from withdrawing. The wire plate 223 is a groove-shaped structure, one end of the wire plate 223 is connected to the first three-axis moving device 21, and the other end faces the winding mechanism 30 and is provided with the guide pin 224, so that the wire plate 223 and the guide pin 224 extend to a certain length to avoid affecting the rotation of the winding mechanism 30.

[0027] The winding mechanism 30 includes a bracket 31 arranged on the machine 10, a rotating component 32 arranged on the bracket 31, a locking component 33 arranged on the bracket 31, at least one first winding component 34 arranged on the rotating component 32, a second winding component 35 arranged on the first winding component 34, and a wire clamping component 36 arranged on the first winding component 34.

[0028] The bracket 31 is used to set the rotating assembly 32 and the locking assembly 33, and its structure can be set as needed.

[0029] The rotating assembly 32 is used to drive the first winding assembly 34 to rotate so that the coil frame rotates to perform winding. The rotating assembly 32 is composed of a rotating motor, a belt, a rotating wheel and other components, which should be existing technologies and will not be described in detail here.

[0030] The locking assembly 33 includes two first cylinders 331 arranged on the bracket 31, a first moving plate 332 arranged on the first cylinder 331, four guide shafts 333 arranged on the first moving plate 332, a second cylinder 334 arranged on the first moving plate 332, a second moving plate 335 arranged on the second cylinder 334, a fixture locking rod 336 arranged on the first moving plate 332, and a clamping wire locking rod 337 arranged on the first moving plate 332. The output end of the first cylinder 331 is connected to the first moving plate 332, and the moving direction of the first cylinder 331 is vertical movement. The guide shafts 333 are located at the four corners of the first moving plate 332, and the first moving plate 332 is driven to move vertically by the first cylinder 331. A through hole 3321 is provided in the center of the first moving plate 332, and the through hole 3321 is used to penetrate and accommodate the second moving plate 335 and the first winding assembly 34. The second cylinder 334 and the second movable plate 335 are located in the through hole 3321. The second cylinder 334 moves vertically and drives the second movable plate 335 to move. The fixture locking rod 336 and the clamping wire locking rod 337 move with the first movable plate 332 and are used to unlock the second winding assembly 35 and the clamping wire assembly 36. How the second movable plate 335, the fixture locking rod 336, and the clamping wire locking rod 337 unlock the first winding assembly 34 will be described below in conjunction with the first winding assembly 34.

[0031] The first winding assembly 34 includes a rotating shaft 341 arranged on the rotating assembly 32, a first fixture seat 342 arranged on the rotating shaft 341, two first clamping claws 343 slidably arranged in the first fixture seat 342, and a winding locking rod 344 movably inserted on the rotating shaft 341.

[0032] The rotating assembly 32 drives the rotating shaft 341 to rotate, thereby driving the entire first winding assembly 34 to rotate for winding. The first fixture seat 342 is used to place the coil frame 100 that needs to be wound. The first clamping jaw 343 includes a slider 3431 slidably arranged on the first fixture seat 342, a claw 3432 arranged at one end of the slider 3431, and a sliding guide 3433 arranged at the other end of the slider 3431. The claw 3432 is located at the end of the slider 3431 facing the coil frame 100. The sliding guide 3433 is located at one end close to the winding locking rod 344. A spring is arranged between the two first clamping jaws 343, so that the two first clamping jaws 343 are separated by the spring, so that the two claws 3432 release the coil frame 100 to achieve unlocking. Two connecting rods 3341 extending from the rotating shaft 341 are arranged on the outer wall of the winding locking rod 344. The winding locking rod 344 is provided with a spring at one end facing the rotating assembly 32, and a U-shaped guide portion 3441 is provided at one end facing the first clamping jaw 343. The winding locking rod 344 moves toward the first clamping jaw 343 under the action of the spring, so that the guide portion 3441 embraces the two sliding guide portions 3433, so that the two clamping jaws 343 are close to clamp the coil frame 100. When unlocking is required, the second moving plate 335 moves down and presses down the connecting rod 3341, so that the winding locking rod 344 moves down, and the two first clamping jaws 343 are separated by the spring between them, so that the two buckling claws 3432 release the coil frame 100.

[0033] The second winding assembly 35 includes an adjusting block 351 movably disposed on the rotating shaft 341 , a second fixture seat 352 disposed on the adjusting block 351 , and two second clamping jaws 353 slidably disposed on the second fixture seat 352 .

[0034] The adjusting block 351 is movably mounted on the rotating shaft 341 at one end and fixed by a fastener, and the second jig seat 352 is provided at the other end, so that the adjusting block 351 rotates with the rotating shaft 341 and drives the second jig seat 352 to rotate around the first winding assembly 34. The second jig seat 352 and the second clamping jaw 353 are the same as the first jig seat 342 and the first clamping jaw 343, and are also used to place and fix the coil frame 100. However, the second jig seat 352 is used to place the coil frame 100 that has been wound, while the first jig seat 342 is used to place the coil frame 100 that needs to be wound. The unlocking of the second jig seat 352 and the second clamping jaw 353 is achieved by moving the first movable plate 332 to drive the jig locking rod 336. The jig locking rod 336 is unlocked when it is inserted and locked when it is released.

[0035] The first jig seat 342 and the second jig seat 352 are no longer at the same height. The height of the first jig seat 342 is higher than the height of the second jig seat 352, so as to avoid the wire being wound onto two coil frames at the same time during rotational winding, so as to ensure the normal winding of the first jig seat 342. The distance between the first jig seat 342 and the second jig seat 352 is twice the length of the coil frame 100, so that the two coil frames 100 can be perfectly spliced ​​together when the winding is completed, thereby ensuring the length of the wire. At the same time, the second winding assembly 35 can adjust the distance from the first jig seat 342 through the adjustment block 351, so as to determine the length of the wire according to the specifications of the coil frame 100, which is suitable for coil frames of different specifications and is also convenient to adjust.

[0036] During winding, the loading and unloading mechanism 40 transports the coil frame 100 to the first fixture seat 342 and locks it. The external wire clamping device pulls the wire extending from the guide pin 244 to the wire clamping assembly 36 and clamps it, and then the rotating assembly 32 drives the first winding assembly 34 to rotate, and the guide pin 244 does not move, so that the wire is wound onto the coil frame 100. After the winding of the first coil frame 100 is completed, the external wire cutting device cuts the wire clamped by the wire clamping assembly 36, and the loading and unloading mechanism 40 moves the coil frame 100 that has been wound to the second fixture seat 352, and places another empty coil frame 100 on the first fixture seat 342, and then starts winding again, so that the second coil frame 100 is also wound, thereby completing the winding of the twin coils. Multiple twin coils are wound by using multiple jigs of different heights, and the coil frame 100 to be wound is placed on the jig at the highest position. The coil frame 100 that has been wound rotates around the jig in the center to avoid other coil frames that have been wound. It can be imagined that this embodiment illustrates the situation of winding twin coils. When more coil frames need to be wound, it is only necessary to increase the number of the second winding assemblies 35 and move the wound coil frames down one by one. The wire clamping assembly 36 is used to clamp the starting wire during winding, and the first movable plate 332 drives the wire clamping locking rod 337 to move up to achieve unlocking.

[0037] The loading and unloading mechanism 40 includes a second three-axis moving device 41 disposed on the machine table 10, and a plurality of clamps 42 disposed on the second three-axis moving device 41. The second three-axis moving device 41 drives the clamps 42 to move so that the clamps 42 clamp or place the coil skeleton, which should be the prior art and will not be described in detail here.

[0038] Compared with the prior art, the second jig seat 352 of the efficient winding system for winding multiple coils provided by the present invention is movably arranged on the rotating shaft 341 through the adjusting block 351, so that the height of the first jig seat 342 is higher than the height of the second jig seat 352. The first jig seat 342 is used to place the coil frame 100 to be wound, and the second jig seat 352 is used to place the coil frame 100 that has been wound. Multiple jigs of different heights are used to wind multiple coils, and the coil frame 100 to be wound is placed on the jig at the highest position. The coil frame 100 that has been wound rotates around the jig in the center, avoiding other coil frames that have been wound. At the same time, the second winding assembly 35 can adjust the distance from the first jig seat 342 through the adjusting block 351, so as to determine the length of the wire according to the specifications of the coil frame, which is suitable for coil frames of different specifications and is also convenient to adjust.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
