Description

Technical Field

[0001] The invention belongs to the field of machinery, and in particular relates to an inductor coil winding device. Background Art

[0002] Existing toroidal inductor coils are usually made by winding a wire around a toroidal iron core. However, existing winding devices usually use two manipulator structures, that is, one manipulator allows the wire to pass through the coil, and the other manipulator contacts the coil and sends the wire back to the first manipulator, and then continues to wind. This winding method requires continuous clamping and wire loosening by the manipulator. Therefore, it is usually only suitable for inductor coils with fewer windings and shorter wires (the winding length depends on the length of the manipulator arm), and it requires precise connection of the wires. The scrap rate is high in actual use, so it needs to be improved. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses an inductor coil winding device. The present invention drives the wire to rotate and move along the wire groove through a circular wire groove and a clamping roller, so that the wire continuously passes through the coil, thereby realizing the winding of the coil, greatly increasing the winding length of the inductor, and does not require a precise manipulator to articulate the wire, so it is not easy to be damaged, and the qualified finished product rate is high.

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1

[0020] like Figure 1 and Figure 2 An inductor coil winding device shown includes a wire conveying structure 1, a wire breaking mechanism 2, a wire winding mechanism 3 and a coil feeding mechanism 4;

[0021] The wire winding mechanism 3 includes a wire plate 31, in which a circular wire groove 32 is formed; two sets of clamping rollers 33 are symmetrically installed at the wire groove 32, and the clamping rollers 33 are connected to a first rotating power structure 34; the coil feeding mechanism 4 includes a vibrating feeder 41, and the vibrating feeder 41 is connected to an L-shaped coil feeding track 42, and a U-shaped groove 43 is installed below the L-shaped coil feeding track 42, and a first push-pull device 44 is installed at the outer end of the U-shaped groove 43, and the first push-pull device 44 is connected to a push-pull device 44. The plate 45 has a rotating wheel 46 connected to the other end thereof, and the rotating wheel 46 is connected to a second rotating power device 47; a first lifting device 48 is installed on the upper inner side of the rotating wheel 46, and the first lifting device 48 is connected to a first limiting wheel 49; a second push-pull device 410 is installed horizontally on the inner side of the rotating wheel 46, and the second push-pull device 410 is connected to a second limiting wheel 411; an L-shaped pressing rod 412 is installed on one side of the U-shaped groove 43, and the L-shaped pressing rod 412 is connected to a third push-pull device 413. An arc-shaped protrusion 414 is formed on the U-shaped groove 43.

[0022] The wire conveying structure 1 comprises a wire wheel 11 and a wire feeding roller pair 12 which are sequentially arranged along the guiding transmission direction, and the wire feeding roller pair 12 is connected to a servo motor 13 .

[0023] A cavity 14 is formed in the middle of the wire board 31, and a triangular wire clamping plate 15 is formed in the cavity 14. The first rotary power structure 34 includes a first rotary motor 341, and the first rotary motor 341 is connected to a rotating shaft 342, and two transmission wheels 344 are fixed on the rotating shaft 342, and the transmission wheels 344 are connected to the clamping roller 33 through a transmission belt 343.

[0024] The first push-pull device 44, the first lifting device 48 and the second push-pull device 410 are all cylinders; the second rotary power device 47 is a stepping motor.

[0025] The first limiting wheel 49 and the second limiting wheel 411 are both elastic wheels.

[0026] The nip roller 33 is a rubber nip roller.

[0027] The wire cutting mechanism 2 comprises a fixed knife 21 and a movable knife 22 , and the movable knife 22 is connected to a movable knife lifting cylinder 23 .

[0028] The method of using the present invention is as follows:

[0029] The vibrating feeder 41 transports the coil 5 to the U-shaped groove 43, and then the second push-pull device 410 extends, driving the second limiting wheel 411 to extend outward, and the third push-pull device 413 pushes the coil to between the second limiting wheel 411 and the rotating wheel 46, and then the first lifting device 48 descends to drive the first limiting wheel 49 downward, thereby limiting the coil 5 between the three wheels.

[0030] Then the wire feeding roller 12 rotates so that the wire enters the wire groove 32 and is clamped and transported by the clamping roller 33, and the wire passes through the coil restricted between the three wheels. When the tail of the wire reaches the coil, the L-shaped wire pressing rod 412 extends forward and presses the wire on the L-shaped wire pressing rod 412 on the side of the coil 5, and then the clamping roller 33 drives the wire to move along the wire groove 32 and continuously pass through the coil 5, so that the wire is wound on the coil, wherein the first two windings press the tail end wire on the two turns of winding first inside and then the L-shaped wire pressing rod 412 retracts. When the wire is wound, the rotating wheel 46 rotates slowly, thereby driving the coil to rotate slowly, so that the coil is continuously wound on the coil. When the winding is completed, the first lifting device 48 and the second push-pull device 410 retract, so that the wound inductor coil falls into the cavity 14, and the third push-pull device 413 pushes the next coil to carry out the next cycle.
