All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-8 , the present invention provides a technical solution: a motor coil winding device, including a bottom plate 1, a bearing plate 2 and a driving mechanism provided on the bottom plate 1. A vertical frame 15 is provided at the top end of the bottom plate 1, and a fixing plate 18 is provided on the vertical frame 15. A slide rail 181 is fixedly provided on the middle surface of the fixing plate 18, and a slide plate 3 is arranged in the slide rail 181. A driving component is also provided on the vertical frame 15, and the driving component is used to drive the slide plate 3 to move vertically. A main gear 22 is provided at the top end of the bearing plate 2, and a push frame 27 is slidably arranged on the inner wall of the main gear 22. One end of the surface of the main gear 22 meshes with a driven gear 23, and the extended end of the shaft of the driven gear 23 penetrates through the bearing plate 2 and is fixedly connected with a first bevel gear 24. Two opposite baffles 26 are provided at the bottom end of the bearing plate 2, and a lead screw 112 is rotatably inserted between the two baffles 26. A nut block 46 is threadedly inserted on the surface of the lead screw 112, and a top plate 4 is movably sleeved on the surface of the nut block 46. The top plate 4 and the push frame 27 are slidably pressed against each other; the driving mechanism includes a stepping motor 11, and the output end of the stepping motor 11 is connected with a support rod 111 through a coupling. A second bevel gear 25 is fixedly sleeved on the shaft of the support rod 111. The second bevel gear 25 is meshed and connected with the first bevel gear 24. The extended end of the support rod 111 passes through the baffle 26 and is fixedly connected with the lead screw 112. Adjusting the driving component to drive the slide plate 3 to move vertically is convenient for providing power for the winding of the winding equipment. Driving the stepping motor 11 enables its output end to drive the connected support rod 111 to rotate through the coupling. The rotating support rod 111 can drive the second bevel gear 25 sleeved on its surface. Due to the meshing connection between the first bevel gear 24 and the second bevel gear 25, the rotating second bevel gear 25 is convenient for driving the first bevel gear 24, thereby being able to drive the driven gear 23 to rotate. The rotating driven gear 23 further drives the main gear 22 meshed at one end, which is beneficial to realizing the rotation of the motor coil clamped on the inner wall of the main gear 22, achieving the effect of reciprocally rotating the wire column in the motor coil, and being convenient for the winding equipment to wind the motor coil. The driven support rod 111 can also synchronously drive the connected lead screw 112 to rotate. The rotating lead screw 112 is convenient for driving the nut block 46 inserted on its surface to move towards one end of the baffle 26. The driven nut block 46 can drive the top plate 4 at the top to slide. When the top plate 4 slides and presses against the arc-shaped protruding end at the bottom of the push frame 27, it is convenient to push out the inner ring of the motor placed in the main gear 22, which is beneficial to quickly taking out the motor coil after winding. A clamping ring for tensioning the motor wire is arranged on the surface of the fixing plate 18.

[0028] The driving assembly includes a servo motor 16. The output end of the servo motor 16 penetrates through the vertical frame 15 and is fixedly connected with an eccentric wheel 17. The sliding plate 3 is located directly above the axis of the main gear 22. A fixed wheel 31 is inserted into the sliding plate 3. The recess of the wheel axle of the fixed wheel 31 is in sliding extrusion with the outer peripheral side of the eccentric wheel 17. A wire rod is fixedly connected to the bottom end of the sliding plate 3, and a wire wheel corresponding to the position of the wire rod is arranged on one side of the bottom of the sliding plate 3. By driving the servo motor 16 to work, the connected eccentric wheel 17 is driven to rotate. The rotating eccentric wheel 17 is in sliding extrusion with the fixed wheel 31 on the surface, so that the driven fixed wheel 31 drives the sliding plate 3 to move vertically back and forth along the slide rail 181, conveys the external motor wire along the inside of the snap ring to the wire wheel, and then conveys the motor wire slidably connected to the surface of the wire wheel to the wire rod, so that the motor wire is wound around one of the wire columns in the motor coil, which is convenient for the driven sliding plate 3 to drive the wire rod to wind the motor coil.

[0029] Both ends of the slide rail 181 are fixedly connected with connecting frames 32. Elastic springs 33 are arranged in both connecting frames 32. The extending ends of the two elastic springs 33 are both connected with connecting plates 34. One ends of the two connecting plates 34 far from the elastic springs 33 are fixedly connected with the corresponding two ends of the plate body of the sliding plate 3 through hinge ear seats. The elastic springs 33 and the connecting plates 34 are used in cooperation and act on the sliding plate 3, which is convenient for the moving sliding plate 3 to reset and enables the eccentric wheel 17 to always be in sliding contact with the fixed wheel 31.

[0030] The connecting frame 32 is in an "L" shape, and a rod groove is opened at one end of the connecting frame 32 opposite to the sliding plate 3. The opened rod groove is convenient for the connecting plate 34 to move along one end of the connecting frame 32.

[0031] A pin 42 is vertically inserted into the top plate 4. A movable plate 43 is slidably sleeved on the surface of the pin 42. A plate hole matched with the movable plate 43 is opened on the screw block 46. A moving plate 45 perpendicular to the movable plate 43 is inserted into the top plate 4. A shaft block 44 is fixedly connected to one end of the movable plate 43 close to the moving plate 45. A "V"-shaped shaft hole matched with the shaft block 44 is opened on the moving plate 45. When the stepping motor 11 is driven to rotate in the reverse direction, the driven support rod 111 drives the lead screw 112. The rotating lead screw 112 drives the screw block 46 to move horizontally. The driven screw block 46 drives the top plate 4 and the moving plate 45. When the moving plate 45 contacts the baffle 26, the movable plate 43 will move along the "V"-shaped shaft hole of the moving plate 45 through the shaft block 44, and then drive the movable plate 43 to move vertically along the pin 42, so that the bottom end of the movable plate 43 slides out of the plate hole on the screw block 46, achieving the effect of the screw block 46 rotating by itself, which is beneficial to prevent the top plate 4 and the baffle 26 from hitting each other. Effectively avoid the contact between the top plate 4 and the baffle 26.

[0032] A plurality of pulleys 21 are provided at the top of the bearing plate 2. The plurality of pulleys 21 are all slidably connected to the main gear 22. A plurality of chutes are provided on the inner wall of the axle of the main gear 22. Both ends of the push frame 27 are slidably placed on the corresponding inner walls of the chutes, and the push frame 27 is of an arc structure. A leakage groove matching the push frame 27 is provided on the bearing plate 2. The sliding fit between the plurality of pulleys 21 and the main gear 22 facilitates the smoother rotation of the main gear 22 during rotation. The chutes are used to place the push frame 27 and the motor coil, and the leakage groove is convenient for placing the push frame 27. The arc-shaped push frame 27 is convenient for sliding and squeezing with the top plate 4, so that the motor coil slides out of the chute, which is convenient for ejecting the motor coil after winding is completed.

[0033] A limiting rod 28 is also fixedly connected between the two baffles 26. The top plate 4 is slidably sleeved on the outer surface of the limiting rod 28, which is beneficial to the stability of the movement of the top plate 4. At the same time, under the cooperation of the screw block 46 and the movable plate 43, the sleeved top plate 4 is driven to move horizontally.

[0034] A plurality of bases 12 are detachably installed on the bottom plate 1. A guide rod 13 is connected between two of the bases 12. The bearing plate 2 is sleeved on the rod shaft of the guide rod 13 through a sleeve rod 14. The detachably installed bases 12 facilitate the replacement of the sleeve rod 14 sleeved on the guide rod 13 and the connected bearing plate 2, so as to realize the adjustment and replacement of coils of different specifications.

[0035] The number of the bases 12 is specifically four, and the bases 12 are respectively connected to the bottom plate 1 and the guide rod 13 through screws, which is convenient for supporting the bearing plate 2. The screws are used to fix the bases 12 to the bottom plate 1 and to fix the guide rod 13 between the two bases 12.

[0036] Working principle: First, place the motor coil in the chute on the inner wall of the main gear 22. At this time, the motor coil is located at the top of the push frame 27. Thread the externally connected motor wire through the snap ring on the fixed plate 18 and convey it downward, so that the motor wire slides along the surface of the wire wheel on the slide plate 3. Then, make the motor wire penetrate the slide plate 3 and be led out by the wire rod at the bottom of the slide plate 3, and fix the led-out motor wire to one end inside the motor coil by winding. Then, drive the servo motor 16 to work, driving the connected eccentric wheel 17 to rotate. The rotating eccentric wheel 17 slides and presses against the fixed wheel 31 on the surface, causing the driven fixed wheel 31 to drive the slide plate 3 to move vertically back and forth along the slide rail 181, facilitating the driven slide plate 3 to drive the wire rod to wind the motor coil. At the same time, drive the stepper motor 11, and its output end drives the connected support rod 111 to rotate through a coupling. The rotating support rod 111 can drive the second bevel gear 25 sleeved on its surface. Due to the meshing connection between the first bevel gear 24 and the second bevel gear 25, the rotating second bevel gear 25 is convenient for driving the first bevel gear 24, thereby being able to drive the driven gear 23 to rotate. The rotating driven gear 23 further drives the main gear 22 engaged at one end, which is beneficial to realizing the synchronous rotation of the motor coil clamped on the inner wall of the main gear 22, achieving the effect of the reciprocating rotation of the wire column inside the motor coil. Then, in cooperation with the vertically moving slide plate 3 and the motor wire in the wire rod at the bottom, when the motor wire is on one side of one wire column inside the motor coil, rotate the main gear 22 to drive the motor coil to make the motor wire pass through the wire column, and at the same time drive the slide plate 3 to move vertically, which is convenient for winding the wire column inside the motor coil. Repeating this process multiple times can realize the winding of the wire column. Drive the main gear 22 to rotate the wire column inside the motor coil to the next one, which is convenient for adjusting and winding different positions of the motor coil. When the stepper motor 11 rotates in the reverse direction, the driven support rod 111 drives the lead screw 112, and the rotating lead screw 112 drives the nut block 46 to move horizontally. The driven nut block 46 drives the top plate 4 and the moving plate 45, so that the top plate 4 moves from one end of the baffle 26 to the other baffle 26. When the top plate 4 slides and presses against the arc-shaped protruding end at the bottom of the push frame 27, it is convenient to push out the inner ring of the motor placed in the main gear 22, which is beneficial to quickly pushing out the motor coil after winding from the main gear 22. When the moving plate 45 contacts the baffle 26, the movable plate 43 will move along the "V"-shaped shaft hole of the moving plate 45 through the shaft block 44, and then drive the movable plate 43 to move vertically along the pin 42, so that the bottom end of the movable plate 43 slides out of the plate hole on the nut block 46, achieving the effect of the self-rotation of the nut block 46.
