Please refer to fig. 1 to 6. The embodiment of the application provides a forming device for winding an alpha coil based on a wire storage mode, which comprises a mounting seat 1, a winding mechanism 2 and a wire feeding mechanism 3.

As shown in fig. 1 and 3, the mount 1 includes an upper mounting portion 11, a lower mounting portion 12, and a connecting portion 13. The upper and lower ends of the connection portion 13 are connected to one ends of the upper and lower mounting portions 11 and 12 in the first horizontal direction X, respectively. The upper mounting portion 11 is fitted with an upper spindle 14 and the lower mounting portion 12 is fitted with a lower spindle 15, both the upper spindle 14 and the lower spindle 15 extending in the vertical direction Z and being coaxial. The mounting base 1 is provided with a first driving member 17 for driving the upper spindle 14 to move up and down, and a second driving member 18 for driving the upper spindle 14 and the lower spindle 15 to rotate synchronously.

As shown in fig. 1 and 4, the winding mechanism 2 includes a wire storage ring 21, an upper jig 22, and a lower jig 23 disposed from top to bottom. The wire storage ring 21 is fixedly connected with the upper spindle 14, the upper jig 22 is fixedly connected with the wire storage ring 21, and the lower jig 23 is fixedly connected with the lower spindle 15.

As shown in fig. 1 and 5, the wire feeding mechanism 3 is provided at a side of the lower mounting portion 12 facing away from the connecting portion 13 in the first horizontal direction X for feeding the wire 10 to the wire storage ring 21. The wire feeding mechanism 3 includes a wire feeding rail 31 extending in the second horizontal direction Y, and a guide pin 32 provided on the wire feeding rail 31, the guide pin 32 being provided with a through hole (not shown) extending in the second horizontal direction Y for accommodating the wire 10. The second horizontal direction Y is perpendicular to the first horizontal direction X and both are perpendicular to the vertical direction Z.

According to the forming device based on the wire storage mode and used for winding the alpha coil, the wire winding mechanism 2 is arranged through the installation seat 1, and the wire feeding mechanism 3 is arranged for feeding wires; because wire winding mechanism 2 includes stores up wire loop 21, wire winding mechanism 2 is carried to wire winding mechanism 2 with lead wire 10 to wire winding mechanism 3's guide pin 32, can store up the line to wire 10 round through storing up wire loop 21 earlier, and the last tool 22 of rethread wire winding mechanism 2 and lower tool 23 are normally coiled to wire 10, and the normal wire winding is after the end to expand the wire storage number on storing up wire loop 21, and the wire storage number after will expanding winds into normal number, can obtain alpha coil. The forming device can meet the product requirement of customers on the alpha coil, and provides reliability for the alpha coil in the next process.

Because the wire storage ring 21 and the upper jig 22 are fixedly connected with the upper spindle 14, the lower jig 23 is fixedly connected with the lower spindle 15, the wire storage ring 21 and the upper jig 22 are driven to rotate by the upper spindle 14, and the lower jig 23 is driven to rotate by the lower spindle 15 so as to store wires and perform normal winding; the upper spindle 14 drives the wire storage ring 21 and the upper jig 22 to move up and down so as to change the layer number of the coil; thereby realizing the orderly arrangement of the multi-layer coil.

Further, one of the main characteristics of the alpha coil is that the start wire 101 and the tail wire 102 are overlapped in a crossing way, and the positions of the crossing points are not fixed due to other winding forming devices and modes. Therefore, the forming device based on the wire storage mode and wound around the alpha coil can meet the requirements of orderly arrangement of the multi-layer coil and fixed positions of the tail wires in a crossing manner.

In the present embodiment, the connecting portion 13 is provided with an intermediate shaft 16 extending in the vertical direction Z, the upper end of the intermediate shaft 16 is connected to the upper spindle 14 by a first timing belt 19, and the lower end of the intermediate shaft 16 is connected to the lower spindle 15 by a second timing belt 110. The second driving element 18 is connected to the intermediate shaft 16, and is used for driving the intermediate shaft 16 to rotate, so that the intermediate shaft 16 drives the upper main shaft 14 to rotate through the first synchronous belt 19, and drives the lower main shaft 15 to rotate through the second synchronous belt 110. By designing the lengths of the first and second timing belts 19 and 110, the rotational speeds of the upper and lower spindles 14 and 15 are equalized, for example, the upper spindle 14 (driving the upper jig 22) rotates 30 degrees, and the lower spindle 15 rotates 30 degrees together in synchronization (driving the lower jig 23).

As shown in fig. 3, the first driving member 17 is preferably fixedly installed at the upper mounting portion 11 so as to conveniently drive the upper spindle 14 to move up and down. An intermediate transmission member can be arranged between the first driving member 17 and the upper main shaft 14, so that the first driving member 17 is not required to be directly arranged right above the upper main shaft 14, the space utilization is more reasonable, and meanwhile, the two actions of up-and-down movement and axial rotation of the upper main shaft 14 can be ensured not to be mutually interfered. The upper spindle 14 may be rotated, moved up and down, or rotated while being moved up and down.

The number of layers/thickness of the coil can be controlled by moving the upper spindle 14 up and down, and wire storage winding, normal winding or wire storage unwinding can be realized by rotating the upper spindle 14. During wire storage winding and normal winding, the upper spindle 14 rotates forward; when the storage wire needs to be deployed, the upper spindle 14 is reversed.

Preferably, the second driving member 18 is fixedly mounted on the lower mounting portion 12, so as to avoid that excessive components of the upper mounting portion 11 affect the balance of the whole mounting seat 1. The lower spindle 15 only needs to perform rotational movement and is fixed in the vertical direction Z, and the lower jig 23 can be used as a reference.

In this embodiment, a jig core 24 is disposed at the center of the lower jig 23, and a core drawing portion connected to the jig core 24 is disposed in the lower spindle 15 for driving the jig core 24 to move up and down. Specifically, the diameter of the jig core 24 is adjustable, so that the size of the inner diameter of the coil can be controlled. When normal winding is completed after wire storage, the coil is wound on the jig core 24, and finally the coil and the jig core 24 are peeled off in a core pulling mode.

As shown in fig. 2 and 4, the winding mechanism 2 further includes a first driving block 25 and a first pin 26 fixedly connected, and a second driving block 27 and a second pin 28 fixedly connected. The first driving block 25 is used for driving the first pin 26 to move up and down, and the second driving block 27 is used for driving the second pin 28 to move up and down. The first driving block 25 and the second driving block 27 are located below the lower jig 23, the first pin 26 and the second pin 28 extend along the vertical direction Z and penetrate through the lower jig 23, and the distances from the first pin 26 and the second pin 28 to the axis of the lower jig 23 are equal. When the coil has a bending requirement (e.g., wire 101 and tail 102 need to be bent 90 ° at the root and then extended), it is necessary to move the first pin 26 and the second pin 28 up to the bending positions of the two points, respectively. Specifically, when the bending step is reached, the first driving block 25 or the second driving block 27 pushes the first pin 26 or the second pin 28 upwards, and after the jig rotates by a certain angle, the first pin 26 or the second pin 28 blocks the wire lifting 101 or the tail wire 102, so that the wire end of the wire lifting 101 or the tail wire 102 forms an angle with the coil body, and bending is realized.

In the present embodiment, the first pin 26 is used for bending the wire 101, the second pin 28 is used for bending the tail wire 102, and the first pin 26 and the second pin 28 are preferably circular pins.

As shown in fig. 1, the forming device further includes a bending unlocking mechanism 4, and the bending unlocking mechanism 4 includes a first unlocking ring 41 and a second unlocking ring 42. The second unlocking ring 42 surrounds the second unlocking ring 42, and the first unlocking ring 41 and the second unlocking ring 42 are both coaxially arranged with the lower jig 23. The distance from the bottom of the first driving block 25 to the axis of the lower jig 23 is smaller than the distance from the bottom of the second driving block 27 to the axis of the lower jig 23, so that part of the first unlocking ring 41 is located right below the bottom of the first driving block 25, and part of the second unlocking ring 42 is located right below the bottom of the second driving block 27, so that the first unlocking ring 41 can push the first driving block 25 upwards, and the second unlocking ring 42 can push the second driving block 27 upwards.

As shown in fig. 2, the bending unlocking mechanism 4 further includes a third driving member 43 and a fourth driving member 44, where the third driving member 43 is connected to the first unlocking ring 41 and is used to drive the first unlocking ring 41 to drive the first driving block 25 to move up and down. The fourth driving member 44 is connected to the second unlocking ring 42, and is used for driving the second unlocking ring 42 to drive the second driving block 27 to move up and down. The third driving piece 43 and the fourth driving piece 44 are fixedly provided at the lower mounting portion 12.

In the present embodiment, as shown in fig. 1, the molding apparatus further includes a knock out mechanism 5 located on the side of the mount 1 out line in the second horizontal direction Y, and the knock out mechanism 5 has a component of the first horizontal direction X and the second horizontal direction Y in the advancing direction and faces away from the connecting portion 13 in the first horizontal direction X. The ejector mechanism 5 is flush with the top surface of the lower jig 23. Because the coil is wound on the jig core 24, the phenomenon that the coil sticks to the jig core 24 occurs after long-time heating (heating is related to a hot air gun 6 described later), and the coil cannot be completely peeled off only by pulling the core by the lower jig 23, the coil needs to be lifted off from the jig core 24 by the demolding and discharging mechanism 5 under the coil, so that the coil can be peeled off intact. After winding, the demolding and discharging mechanism 5 moves forward, and then the coil is ejected out, so that the coil is separated from the jig core 24 of the lower jig 23; the upper jig 22 is moved up to a proper safety height before the mold release mechanism 5 is advanced. The demolding and discharging mechanism 5 is only used for ejecting the coil, so that the coil and the jig core 24 are separated, and the coil can be conveniently and smoothly taken out by a subsequent manipulator.

As shown in fig. 5, the wire feeding mechanism 3 further includes a wire feeding clamp 33 and a wire storing clamp 34, the wire feeding clamp 33 extending in the first horizontal direction X, and the wire storing clamp 34 extending in the second horizontal direction Y. Wherein the wire feeding clip 33 and the guide pin 32 are used together for feeding a wire. The winding mechanism 2 is provided with a wire takeup clamp 29 for clamping the wire takeup 101 above the wire storage ring 21. After the wire clamp 33 and the guide pin 32 send the wire 10 to the winding mechanism 2, the wire clamp 29 clamps the wire 10, at this time, the wire clamp 33 can loosen the wire 10, the guide pin 32 can stay at a position, and the guide pin 32 can not move until the winding is finished. When normal winding and tail wire 102 bending are completed, the wire feeding clamp 33 is used for breaking the wire, then the wire lifting 101 is clamped by the wire storage clamp 34, the wire storage on the wire storage ring 21 can be unfolded by matching with the reverse rotation of the winding mechanism 2, and after that, the unfolded wire storage is continuously rotated by the wire storage clamp 34 and the winding mechanism 2, and the winding action is finished after the normal winding is carried out on the wire storage.

Preferably, the wire storage clamp 34 is provided with a weight 35 at one side of the wire inlet along the second horizontal direction Y, so as to provide a tension effect for winding the last circle, thereby meeting the action function of normal winding. In the winding process of the copper wire, the wire is required to be always in a state of being pulled to be in a straight line, so that a constant force is required to be applied to the head of the wire, and the other end of the wire can be used for winding. The weight 35 has a main function of applying a constant force to one end of the copper wire to tension the copper wire when the unwound storage wire is normally wound.

As shown in fig. 1, the forming device further includes a heat gun 6, the heat gun 6 is disposed toward the winding mechanism 2, and the heat gun 6 is fixedly connected to the connecting portion 13. The main work of the hot air gun 6 is to heat the winding mechanism 2 in the winding process, so that the temperature of the coil wound on the winding mechanism 2 is increased, the chemical coating on the surface of the copper wire is melted, and the adhesion force is generated between the wires, so that the coil is formed without being scattered. The heat gun 6 is always in an open state before and during winding, and can be closed after winding is finished.

As shown in fig. 7a to 7i, in a specific application scenario, when the forming device for winding an alpha coil based on the wire storage manner provided by the embodiment of the application is used for winding, there are approximately nine steps. First, as shown in fig. 7a, the wire feeding mechanism 3 feeds the wire 10 into the wire drawing clamp 29 of the winding mechanism 2, and the wire drawing clamp 33 is released. In the second step, as shown in fig. 7b, the wire 10 is stored one turn by the rotating action of the guide pin 32 and the winding mechanism 2. In the third step, as shown in fig. 7c, the coil is normally started to wind around the (1) th turn by the rotation action of the guide pin 32 and the winding mechanism 2. Fourth, as shown in fig. 7d, the coils are normally arranged in the (2) th turn by the rotation action of the guide pin 32 and the winding mechanism 2. In the fifth step, as shown in fig. 7e, the coils are normally arranged in the (3) th turn by the rotation action of the guide pin 32 and the winding mechanism 2. In the sixth step, as shown in fig. 7f, the coils are normally arranged in the (4) th turn by the rotation action of the guide pin 32 and the winding mechanism 2. In the seventh step, as shown in fig. 7g, the winding mechanism 2 and the guide pin 32 rotate to arrange the winding normally for the (5) th turn, and the tail wire 102 is wound at the (5) th turn, and the bending action of the tail wire 102 is finished through the second driving block 27 and the second pin 28, and then the wire breakage is performed through the wire feeding clamp 33. The eighth step is to pull the wire storage one turn by the reverse rotation of the wire winding mechanism 2 with the wire storage clip 34 holding the wire 101 therebetween, as shown in fig. 7 h. The ninth step is to finish the winding operation around the last turn by the rotation operation of the wire holder 34 and the winding mechanism 2 as shown in fig. 7i, and form an alpha coil having an inner and outer double layer and three rows up and down as shown in fig. 6.

In other embodiments, the device for forming alpha coils based on the wire storage mode provided by the embodiment of the application can be used for winding alpha coils with different layers and rows. The application is suitable for the technical field of manufacturing wireless charging alpha coils, mobile phone transmitting ends and receiving ends for inducing alpha coils, and is a forming device designed based on an alpha coil structure.

The forming device can realize high-efficiency operation by extending working procedures and separating working stations in parallel, can realize the appearance forming of the alpha coil, ensures the reliability of a product manufacturing process, can improve the process quality of the product and meets the requirements of customers. Specifically, the wire storage winding and the normal winding can be separated and operated in parallel, for example, the number of the installation seats 1 can be four, four stations are formed, and the four stations can operate simultaneously. The order of parallel operation is as follows: the first station hot air gun 6 preheats the winding mechanism 2, meanwhile, the second station has completed the wire storage action, the wire is normally wound, the third station performs wire storage and winding work, the fourth station finishes winding, and the blanking is performed.
