[0002] A coil generally refers to a wire winding in a ring shape. The most common coil applications include: motors, inductors, transformers, and loop antennas, etc. Coils need to be wound around a coil skeleton by a winding machine.

[0024] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention here does not limit the protection scope of the present invention.

[0025] As Figures 1 to 10As shown in the figure, it is a schematic structural diagram of an efficient wire winding machine for double-sided circuit boards provided by the present invention. The efficient wire winding machine for double-sided circuit boards includes a machine table 10, a wire storage mechanism 20 located on one side of the machine table 10, a wire passing mechanism 30 arranged on the machine table 10, an upper clamping mechanism 40 arranged on the machine table 10, a lower clamping mechanism 50 arranged on the machine table 10, and a blowing and clamping mechanism 60 arranged on the machine table 10. It can be imagined that the efficient wire winding machine for double-sided circuit boards also includes some other functional modules, such as a control module, and a wire cutting and clamping assembly, etc., which are well-known technologies to those skilled in the art and will not be elaborated here.

[0026] First of all, it should be noted that the coil skeleton 100 for winding the double-sided circuit board of the efficient wire winding machine for double-sided circuit boards has a through hole 110 at the center, a wire clamping port 120 is provided on the through hole 110, and a plurality of pins 130 are provided on the coil skeleton 100. The coil skeleton 100 should be an existing technology and will not be elaborated here.

[0027] The machine table 10 is used to carry the above-mentioned various functional modules, that is, the wire storage mechanism 20, the wire passing mechanism 30, the upper clamping mechanism 40, and the lower clamping mechanism 50. Therefore, the machine table 10 is provided with various functional structures, such as screws, bolts, jigs, etc. to complete the installation and assembly of the above-mentioned functional modules, which can be set according to actual needs and will not be described in detail one by one here.

[0028] The wire storage mechanism 20 includes a plurality of wire storage cylinders 21 and a plurality of wire passing wheels 22. Conductive wires are stored in the wire storage cylinders 21. After the conductive wires extend out of the wire storage cylinders 21, they pass through the wire passing wheels 22 and then enter the wire passing assembly 30. The wire storage mechanism 20 should be an existing technology and will not be elaborated here.

[0029] The wire passing mechanism 30 includes a bracket 31 arranged on the machine table 10, a plurality of tension components 32 arranged on the machine table 10, a plurality of wire passing components 33 arranged on the bracket 31, and a driving component 34 arranged on the bracket 31.

[0030] The tension component 32 is located at the top of the bracket 31 and is used to adjust the tension of the conductive wire.

[0031] In this embodiment, there are six sets of the wire passing components 33. The high-efficiency wire winding machine applicable to double-sided circuit boards can wind six coils simultaneously. Only one of them will be described here. The wire passing component 33 includes a mounting plate 331 arranged on the bracket 31, a plurality of wire passing plates 332 arranged at intervals on the mounting plate 311, a plurality of wire passing tubes 333 respectively arranged on the wire passing plates 332, a plurality of driving wheels 334 arranged on the mounting plate 331, two guiding shafts 335 arranged on the mounting plate 331, a sliding plate 336 slidably arranged on the mounting plate 331, and a plurality of driven wheels 337 arranged on the sliding plate 336.

[0032] The mounting plate 331 is in a long strip shape and its extending direction is parallel to the direction of gravity. One end of the wire passing plate 332 is connected to the mounting plate 331, and the other end is provided with a wire passing tube 333 for passing a wire through. The wire passing tubes 333 on the plurality of wire passing plates 332 are coaxially arranged to ensure the straight delivery of the wire. The wire output from the wire storage mechanism 20 passes through the wire passing component 33 and then passes through the plurality of wire passing tubes 333 in sequence. The driving wheel 334 is located between two adjacent wire passing plates 322. The rotating shaft of the driving wheel 334 passes through the mounting plate 331 and the bracket 31 and is connected to the driving component 34, so as to drive the driving wheel 334 to rotate through the driving component 34. The two guiding shafts 335 are located at the upper and lower ends of the mounting plate 331. One end of the guiding shaft 335 is connected to one side of the mounting plate 331, and the other end is slidably provided with the sliding plate 336. The sliding plate 336 is located on one side of the mounting plate 331 and is connected to the driving component 34, so as to drive the sliding plate 336 and the driven wheels 337 arranged on it to translate through the driving component 34. The number of the driven wheels 337 is the same as that of the driving wheels 334 and they are located in one-to-one correspondence with the driving wheels 334. Thus, when the sliding plate 336 drives the driven wheels 337 to move towards the driving wheels 334, the driving wheels 334 and the driven wheels 337 can clamp the wire, and then the driving wheels 334 rotate to convey the wire.

[0033] The driving component 34 includes a rotary driving device 341 and a translational driving device 342. The rotary driving device 341 is connected to the driving wheel 334 and drives it to rotate for wire feeding. The translational driving device 342 is connected to the sliding plate 336 and drives it to move horizontally, so that the sliding plate 336 drives the driven wheels 337 towards the driving wheels 334 to fit for wire feeding. The rotary driving device 341 and the translational driving device 342 should be prior art and will not be elaborated here.

[0034] The upper clamping mechanism 40 includes a first three-axis moving device 41, a mounting bracket 42 disposed on the first three-axis moving device 41, a plurality of upper clamping cylinders 43 disposed on the mounting bracket 42, a plurality of pressing plates 44 respectively disposed on the upper clamping cylinders 43, a plurality of upper guide pins 45 disposed on the mounting bracket 42, and a plurality of wire cutting clamps 46 disposed on the mounting bracket 42.

[0035] The first three-axis moving device 41 is configured to drive the upper clamping mechanism 40 to move in three axes. The upper clamping cylinder 43 clamps an upper fixture 47 for setting a coil bobbin. The upper fixture 47 includes an upper clamping portion 471, a plug rod 472 disposed on the upper clamping portion 471, an upper fixture through hole 473 disposed on the upper clamping portion 471, a locking rod 474 inserted into the upper fixture through hole 473, a spring 475 sleeved on the locking rod 474, and a plurality of balls 476 disposed on the locking rod 475.

[0036] The upper clamping cylinder 43 fixes and moves the upper fixture 47 by clamping the upper clamping portion 471. The plug rod 472 is disposed at the center of the end face of the upper clamping portion 471 facing the lower clamping mechanism 50. The plug rod 472 is coaxially disposed with the upper clamping portion 471 and is configured to be inserted into the lower clamping mechanism 50. The plug rod 472 is provided with a plurality of through holes 4721 arranged in a circumferential pattern. The balls 476 roll within the through holes 4721. One end of the locking rod 474 is provided with an abutting portion 4741, and the other end is inserted into the upper fixture through hole 473 and is provided with a locking groove 4742. The locking groove 4742 is obliquely connected to the outer side wall of the locking rod 474. The locking groove 4742 is configured to accommodate a part of the balls 476, and during locking, it cooperates with the lower clamping mechanism 50 through the inclined surface of the locking groove 4742 for locking. The specific description will be given below in conjunction with the lower clamping mechanism 50. One end of the spring 475 abuts against the abutting portion 4741, and the other end abuts against the upper clamping portion 471. In the free state, the locking rod 474 is moved away from the lower clamping mechanism 50 by the elastic force of the spring 475.

[0037] The pressing plate 44 is located between the two output ends of the upper clamping cylinder 43, and presses down the locking rod 474 when the upper clamping cylinder 43 clamps the upper fixture 47 to achieve unlocking. The specific description will be given below in conjunction with the lower clamping mechanism 50. The upper guide pin 45 is located between the upper clamping cylinder 43 and the wire cutting clamp 46, and the wire output from the wire passing mechanism 30 passes through the upper guide pin 45. The wire cutting clamp 46 is configured to cut the wire after winding is completed.

[0038] The lower clamping mechanism 50 includes a second three-axis moving device 51, a rotating assembly 52 disposed on the second three-axis moving device 51, a plurality of lower clamping cylinders 53 disposed on the rotating assembly 52, a plurality of lower guide pins 54 disposed on the rotating assembly 52, a vertical moving lead screw 55 disposed on the second three-axis moving device 51, a carrier plate 56 disposed on the vertical moving lead screw 55, a plurality of cylinders 57 disposed on the carrier plate 56, and a plurality of wire clamping cylinders 58 respectively disposed on the cylinders 57.

[0039] The second three-axis moving device 51 is used to drive the lower clamping mechanism 50 to move in three axes, so as to draw a circle together with the first three-axis moving device 41 to wind the wire around the upper and lower surfaces of the skeleton. The rotating assembly 52 is used to rotate the lower guide pin 54 to facilitate the winding of the leads.

[0040] The lower clamping cylinder 53 clamps a lower fixture 59 for setting the coil skeleton. The lower fixture 59 includes a lower clamping portion 591, a lower fixture through hole 592 disposed on the lower clamping portion 591, and an inclined surface 593 disposed on the lower fixture through hole 592. The lower fixture through hole 592 is used to insert the insertion rod 472, and the inner side wall of the lower fixture through hole 592 is provided with the inclined surface 593.

[0041] When fixing the coil skeleton, first place the coil skeleton with the wire threaded thereon on the lower clamping portion 591. Then, the upper clamping cylinder 43 clamps the upper clamping portion 471, and at the same time, the pressing plate 44 also presses down the locking rod 474, so that the ball 476 returns to the locking groove 4742. Then, insert the insertion rod 472 into the lower fixture through hole 592, so that the upper and lower fixtures 47 and 59 clamp and fix the coil skeleton. Then, after the upper clamping cylinder 43 is released, the pressing plate 44 does not press the locking rod 474 anymore. The locking rod 474 moves away from the lower fixture 59 under the action of the spring 475, so that the inclined surface 593 and the inclined surface of the locking groove 4742 clamp the ball 476, thereby preventing the upper fixture 47 and the lower fixture 59 from moving. The locking process is simple. When unlocking is required after winding is completed, only need the upper clamping cylinder 43 to clamp the upper fixture 47 again, the pressing plate 44 will press the locking rod 474 again, so that the ball 476 will roll back into the locking groove 4742, and then the upper fixture 47 can be directly withdrawn.

[0042] The lower guide pin 54 is used to thread the wire output from the upper guide pin 45. After passing through, the wire is clamped by the wire clamping cylinder 58. When threading the wire, the lower guide pin 54 and the upper guide pin 45 are coaxially arranged and close to each other to facilitate wire threading. The vertical movement lead screw 55 can drive the carrier plate 56 to move, thereby driving a plurality of the wire clamping cylinders 58 to move together. After clamping the wire, the carrier plate 56 moves downward to pull out a sufficient length of wire in advance before winding to wind the lower end surface of the coil skeleton, so as to have a wire storage function. While a plurality of the wire clamping cylinders 58 move simultaneously, they can also move independently through the cylinder 57 to adjust the appropriate tension during the winding process to ensure the winding quality and prevent the wire from breaking.

[0043] The blowing and clamping mechanism 60 includes a third three-axis moving device 61, a plurality of clamping cylinders 62 arranged on the third three-axis moving device 61, and a plurality of blowing guns 63 arranged on the third three-axis moving device 61. The third three-axis moving device 61 drives the clamping cylinders 62 to move in three axes, and the clamping cylinders 62 can clamp the coil skeleton 100 for up and down handling.

[0044] During winding, the clamping cylinder 62 clamps the coil skeleton 100 and moves it to the middle of the upper and lower guide pins 45 and 54. The upper and lower guide pins 45 and 54 approach each other and pass through the center of the coil skeleton 100. Then the wire passes through the upper and lower guide pins 45 and 54 and is clamped by the wire clamping cylinder 58, so that the wire passes through the center of the coil skeleton 100 and is stuck into the wire clamping port 120 to complete the threading and fixing of the starting wire. The vertical movement lead screw 55 drives a plurality of the wire clamping cylinders 58 to move downward together to pull out a sufficient length of wire in advance to wind the lower end surface of the coil skeleton. Then the upper and lower clamping mechanisms 40 and 50 move again, so that the coil skeleton 100 is placed on the lower clamp 59, and the upper clamping mechanism 40 clamps the upper clamp 47 and inserts it through the coil skeleton 100 into the lower clamp 59. Then the upper and lower clamps 47 and 59 are loosened, thereby locking the upper and lower clamps 47 and 59 and fixing the coil skeleton. The clamping cylinder 62 always clamps the coil skeleton 100, and the first and second three-axis moving devices 41 and 51 perform circular movement to wind the wire on the upper and lower surfaces of the coil skeleton respectively. The wire pulled out in advance is wound on the lower end surface through the lower guide pin 54, and the wire connected to the wire storage cylinder is wound on the upper end surface through the upper guide pin 45. During the winding process, the blowing and clamping mechanism 60 always blows hot air to heat the wire so as to fix the wire to the coil skeleton. After winding, the wire cutting clamp 46 and the wire clamping cylinder 58 cut off the starting wire and loosen the tail wire respectively to complete the winding.

[0045] Compared with the prior art, when the high-efficiency wire winding machine applicable to double-sided circuit boards provided by the present invention winds wires, the fixture cylinder 62 will clamp the coil skeleton 100 and move it to the middle of the upper and lower guide pins 45 and 54. The lower guide pin 54 and the upper guide pin 45 are coaxially arranged and close to each other, and pass through the center of the coil skeleton 100. Then the wire passes through the upper and lower guide pins 45 and 54 and is clamped by the wire clamping cylinder 58, so that the wire passes through the center of the coil skeleton 100 and is clamped into the wire clamping port 120, automatically completing the wire threading. After clamping the wire, the vertical moving screw rod 55 drives the plurality of wire clamping cylinders 58 to move downward together, and pulls out a sufficient length of wire for the lower end surface of the coil skeleton in advance. When winding the wire, the coil skeleton is fixed by locking the upper and lower fixtures 47 and 59. The fixture cylinder 62 always clamps the coil skeleton 100, and the first and second three-axis moving devices 41 and 51 perform circular movement to wind the wire on the upper and lower surfaces of the coil skeleton respectively, realizing the automatic double-sided winding of the double-sided circuit board coil.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are all covered within the scope of the claims of the present invention.
