[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Refer to Figures 1-9 , a motor automatic wire embedding device, including a wire embedding frame 1, a wire embedding cylinder 2, a top rod 3 and symmetrically arranged rotating pressing plates 4. The wire embedding cylinder 2 is fixedly arranged on the wire embedding frame 1. The top rod 3 is slidably arranged in the wire embedding cylinder 2. During wire embedding, the top rod 3 is ejected from the wire embedding cylinder 2 to embed the copper wire clamped in the wire embedding cylinder 2 into the iron core.

[0036] The wire embedding device further includes a pressure ring 13 and a pressure cover 41. After the rotating pressing plate 4 rotates, it can press the pressure ring 13. The pressure cover 41 is used to keep the insulating paper inside the iron core in a flat state. During use, the iron core is placed at the top of the wire embedding cylinder 2. Subsequently, the pressure ring 13 is manually sleeved on the outer circle of the iron core, and the pressure cover 41 is placed inside the inner circle of the iron core. The driving mechanism of the rotating pressing plate 4 is started to press the pressure ring 13. When the top rod 3 ejects and embeds the copper wire, the pressure cover 41 is ejected. Subsequently, the pressure cover 41 is manually recovered. This is the existing structure and operation process of the existing automatic wire embedding device, and will not be elaborated here too much.

[0037] One side of the wire embedding frame 1 is provided with a button board 5. The button board 5 is provided with a pressing plate button 6 for starting the rotating pressing plate 4 and a top rod button 7 for starting the ejection of the top rod 3. As Figure 6 shown, the top rod button 7 is arranged on the right side of the pressing plate button 6, that is, the pressing plate button 6 is arranged close to one side of the wire embedding frame 1. After the pressing plate button 6 is pressed, the symmetrically arranged rotating pressing plates 4 on both sides can be started to rotate towards the center side of the wire embedding cylinder 2 to press the pressure ring 13 on the iron core of the wire embedding cylinder 2. Preferably, a slidable conductive rod 12 is arranged at the pressing end of the rotating pressing plate 4. As Figure 9 shown, a second spring 25 is arranged between the lower end of the conductive rod 12 and the rotating pressing plate 4. When the rotating pressing plate 4 presses the pressure ring 13, the conductive rod 12 can be pressed against the second spring 25, so that the conductive rod 12 is always in contact with the end face of the pressure ring 13 by relying on the elastic force of the second spring 25.

[0038] A sliding cover 8 that can cover the pressing plate button 6 and the top rod button 7 is slidably arranged on the button board 5. The sliding cover 8 is provided with a pressing groove 9 through which a finger can pass. The pressing groove 9 runs through the sliding cover 8. The sliding cover 8 is a hollow cover. Initially, the pressing groove 9 is located at the left end of the sliding cover 8. As Figure 6 shown, when the sliding cover 8 slides to the right, the pressing groove 9 can be aligned with the pressing plate button 6 and the top rod button 7 in sequence. When the pressing plate button 6 is aligned with the pressing groove 9, a finger can press the pressing plate button 6. Similarly, when the pressing groove 9 is aligned with the top rod button 7, the top rod button 7 can be pressed.

[0039] As Figure 3As shown, several first guide rods 23 are provided at the right end of the sliding cover 8. The first guide rods 23 are slidably disposed through the right side plate of the button plate 5. A first spring 24 is provided between the sliding cover 8 and the right side plate. The first spring 24 is sleeved on the first guide rods 23 and its two ends respectively abut against the sliding cover 8 and the right side plate.

[0040] As Figure 1 shown, a protective cover 10 that can be rotatably opened is provided on the wire embedding frame 1. A damping push rod can be provided between the protective cover 10 and the wire embedding frame 1, so that the operator can slowly open the protective cover 10. A driving block 11 for driving the sliding cover 8 to slide to the right is provided on one side of the protective cover 10 close to the button plate 5. A vertically upward driving plate 22 is provided on one side of the sliding cover 8 close to the protective cover 10. The driving plate 22 and the sliding cover 8 are preferably integrally formed. As Figure 3 shown, a driving inclined surface 21 is provided on the driving block 11. The driving inclined surface 21 inclines downward and away from the sliding cover 8. When the protective cover 8 is closed, the driving inclined surface 21 abuts against the driving plate 22, pushing the sliding cover 8 to the right, so that the pressing groove 9 cooperates with the pressing plate button 6, that is, after the protective cover 10 is closed, the pressing plate button 6 can be pressed.

[0041] A conductive ring 14 is embedded in the upper end surface of the pressure ring 13. After the rotating pressing plate 4 rotates and contacts the pressure ring 13, the conductive rod 12 on the rotating pressing plate 4 can contact the conductive ring 14, so that the conductive rods 12 on the two symmetric rotating pressing plates 4 are connected in series through the conductive ring 14. As Figure 6 shown, an electromagnet 15 is fixedly provided on the lower side plate at the right end of the button plate 5. A first magnetic attraction plate 31 that cooperates with the electromagnet 15 is downwardly extended on the right end surface of the sliding cover 8. The first magnetic attraction plate 31 and the sliding cover 8 are connected by a connecting plate 32. A sliding groove 33 for the connecting plate 32 to slide to the right is provided on the button plate 5. The electromagnet 15 is connected in series with the two symmetric conductive rods 12. That is, when the pressing plate button 6 is pressed, the two conductive rods 12 contact the conductive ring 14 to energize the electromagnet 15 circuit. Subsequently, the electromagnet 15 adsorbs the first magnetic attraction plate 31, making the sliding cover 8 slide further to the right, so that the pressing groove 9 cooperates with the ejector button 7, that is, when the pressing plate button 6 is pressed, the sliding cover 8 can slide and then the ejector button 7 can be pressed.

[0042] As Figure 2 shown, a second magnetic attraction plate 42 that abuts against the pressing cover 41 is slidably provided on the protective cover 10. That is, when the protective cover 10 is closed, that is, as Figure 5In the shown state, the second magnetic attraction plate 42 abuts against the gland 41. A third spring 43 is provided between the second magnetic attraction plate 42 and the protective cover 10. Second guide rods 44 are symmetrically provided on both sides of the second magnetic attraction plate 42. The second guide rods 44 are arranged through the protective cover 10. Preferably, the third spring 43 is sleeved on the second guide rods 44 and its two ends respectively abut against the second magnetic attraction plate 42 and the inner end face of the protective cover 10.

[0043] After the ejector button 7 is pressed, the ejector rod 3 can be ejected, so that the ejector rod 3 cooperates with the gland 41 to eject it towards the protective cover 10. A strong magnetic ring 45 matched with the second magnetic attraction plate 42 is provided on the protective cover 10. The second magnetic attraction plate 42 and the strong magnetic ring 45 are concentrically arranged. After the protective cover 10 is closed, the second magnetic attraction plate 42, the strong magnetic ring 45 and the gland 41 are in concentric positions. When the gland 41 is ejected by the ejector rod 3, the gland 41 and the second magnetic attraction plate 42 are synchronously displaced towards the strong magnetic ring 45. After displacing a certain distance, the strong magnetic ring 45 adsorbs the second magnetic attraction plate 42 due to its own suction force. The second magnetic attraction plate 42 is preferably an iron plate. At this time, the gland 41 is adsorbed by the magnetic attraction force attached to the second magnetic attraction plate 42, that is, the gland 41 is adsorbed on the protective cover 10.

[0044] A power-off switch 46 matched with the second magnetic attraction plate 42 after sliding is provided in the protective cover 10. The power-off switch 46 is electrically connected to the electromagnet 15. That is, after the gland 41 is ejected, the second magnetic attraction plate 42 is abutted against and compresses the third spring 43, so that the second magnetic attraction plate 42 is displaced towards the side close to the protective cover 10. Subsequently, the second magnetic attraction plate 42 contacts the power-off switch 46 to trigger the switch, so that the electromagnet 15 is powered off. At this time, the sliding cover 8 slides leftward to reset under the elastic force of the first spring 24, so that the pressing groove 9 is aligned with the pressing plate button 6 again.

[0045] As Figure 4 shown, a locking pin 51 for locking the sliding cover 8 is slidably provided on the button plate 6. A fourth spring 52 is provided between the locking pin 51 and the sliding cover 8. A first pull rope 53 is provided on the locking pin 51. One end of the first pull rope 53 is fixedly provided on the locking pin 51, and the other end passes through the fourth spring 52, the button plate 5 and the protective cover 10 in sequence and is connected to the second magnetic attraction plate 42. The two ends of the fourth spring 52 respectively abut against the button plate 5 and the locking pin 51. The spring force of the fourth spring 52 is much smaller than the spring force of the third spring 43. Initially, the second magnetic attraction plate 42 is abutted by the fourth spring 52 and is in a natural state. The second magnetic attraction plate 42 tightens the locking pin 51 through the first pull rope 53, so that the fourth spring 52 is compressed. When the second magnetic attraction plate 42 slides towards the side close to the protective cover 10, the fourth spring 52 is relaxed, so that the locking pin 51 slides towards the side close to the sliding cover 8.

[0046] The sliding cover 8 is provided with a lock hole 54 that cooperates with the locking pin 51, that is, when the locking pin 51 is in the adapted position, it can be inserted into the lock hole 54, as Figure 4 shown. When the locking pin 51 cooperates with the lock hole 54, the pressing groove 9 is located on the pressing plate button 6. That is, after the ejector button 7 is pressed, the second magnetic attraction plate 42 simultaneously triggers the power-off switch 46 and the locking pin 51, causing the sliding cover 8 to slide towards the side close to the protective cover 10 and then inserting the locking pin 51 into the lock hole 54, thereby locking the position of the sliding cover 8. At this time, the pressing groove 9 corresponds to the pressing plate button 6. Subsequently, the protective cover 10 is opened, and then by pressing the pressing plate button 6, the rotating pressing plate 4 is moved to the outside of the pressure ring 13. Subsequently, the iron core after wire embedding is taken out, and at the same time, the pressing cover 41 on the protective cover 10 is removed. The second magnetic attraction plate 42 is manually reset. When the second magnetic attraction plate 42 is reset, it pulls the locking pin 51 again, so that the sliding cover 8 covers the pressing plate button 6 and the ejector button 7 again under the elastic force of the first spring 24.

[0047] As the production process of the above motor automatic wire embedding device, the process is as follows:

[0048] S1: The copper wire bundle is clamped into the wire embedding cylinder 2, and then the iron core with insulating paper is placed at the upper end of the wire embedding cylinder 2. The pressure ring 13 is sequentially placed on the outer circle of the iron core, and the pressing cover 41 is placed on the inner circle. At this time, both the pressing plate button 6 and the ejector button 7 are covered by the sliding cover 8;

[0049] S2: The protective cover 10 is closed so that the protective cover 10 covers the upper part of the iron core and the wire embedding cylinder 2. At this time, the second magnetic attraction plate 42 abuts against the pressing cover 41. While the protective cover 10 is being closed, the driving block 11 cooperates with the sliding cover 8 to make the sliding cover 8 slide horizontally, so that the pressing groove 9 is aligned with the pressing plate button 6;

[0050] S3: Press the pressing plate button 6 to make the rotating pressing plate 4 rotate onto the pressure ring 13. At this time, the conductive rod 12 contacts the conductive ring 14 on the pressure ring 13 to close the circuit, so that the electromagnet 15 is energized. At this time, the electromagnet 15 adsorbs the first magnetic attraction plate 31 to make the sliding cover 8 slide further, so that the pressing groove 9 is aligned with the ejector button 7;

[0051] S4: Press the ejector button 7, and the ejector rod 3 ejects the copper wire bundle to make it clamped in the iron core. At the same time, the pressing cover 41 is ejected so that the second magnetic attraction plate 42 is adsorbed by the strong magnetic ring 45. At this time, the pressing cover 41 is also adsorbed on the second magnetic attraction plate 42 through the strong magnetic ring 45. At the same time, the second magnetic attraction plate 42 triggers the power-off switch 46 to cut off the power supply of the electromagnet 15, and the first pull rope 53 is relaxed. Subsequently, the sliding cover 8 slides back, and the pressing groove 9 is aligned with the pressing plate button 6 again. At the same time, the locking pin 51 locks the sliding cover 8;

[0052] S5: Open the protective cover 10. The gland 41 is adsorbed on the protective cover 10. Then press the pressing plate button 6 to disengage the rotating pressing plate 4 from the pressure ring 13, and take out the iron core after winding the wire.

[0053] S6: Remove the gland 41 and manually reset the second magnetic attraction plate 42, so that the locking pin 51 is disengaged from the locking of the sliding cover 8, the sliding cover 8 is reset, and the pressing plate button 6 and the ejector rod button 7 are covered again.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
