Description

Technical Field

[0001] This utility model relates to the field of brushless motor manufacturing technology, specifically to a coil winding device for a hollow cup motor. Background Technology

[0002] The hollow cup motor coil winding equipment is a high-precision automated device specifically designed for manufacturing hollow cup motor coils. Hollow cup motors, due to their coreless rotor design, offer advantages such as high efficiency, low inertia, and high response speed, and are widely used in drones, medical devices, robots, and other equipment. The core function of this equipment is to precisely wind enameled wire onto the hollow cup motor's frame according to specific process requirements, forming the coil structure required for the motor and ensuring consistent winding quality. The hollow cup motor coil winding equipment not only improves production efficiency but also significantly enhances the accuracy and consistency of the coils, making it an indispensable key piece of equipment in the hollow cup motor manufacturing process.

[0003] According to the Chinese Utility Model Publication No. CN218335686U, a hollow cup winding device for a brushless DC motor is disclosed. This device has a compact and reasonable structure, is simple to operate, and is convenient to use. First, the coil to be used is hung on the hanging rod. Then, the hollow cup is clamped by the clamping mechanism. Next, one end of the coil is fixed on the hollow cup. Finally, the copper wire is quickly and orderly wound onto the hollow cup by the clamping mechanism and the winding mechanism. This saves time and effort while improving the winding quality and ensuring the quality of the subsequent finished product.

[0004] However, there are some problems to consider when implementing the above technical solution: First, the device clamps and fixes the hollow cup with a clamping plate, but it is not easy to control the position when holding it by hand, which causes the hollow cup to shift and affect the winding quality. Second, after the raw material is hung on the hanging rod, it needs to be controlled by the limiting sleeve and the first fastening knob, which is cumbersome to operate. Utility Model Content

[0005] The purpose of this utility model is to provide a hollow cup motor coil winding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hollow cup motor coil winding device, comprising a base, a raw material placement mechanism, a wire feeding mechanism, and a winding mechanism. A controller is provided on the front of the base, a raw material placement mechanism is installed on one side of the top of the base, a wire feeding mechanism is installed at the center of the top of the base, and a winding mechanism is installed on the other side of the top of the base.

[0007] Preferably, the raw material placement mechanism includes a central shaft, a bearing, a tray, and a conical frame. The central shaft is welded to one side of the top of the base, a bearing is sleeved on the outside of the central shaft, and a tray is sleeved on the outside of the bearing.

[0008] Preferably, a tapered frame is welded to the top of the tray, and the size of the tapered frame is smaller than the size of the tray.

[0009] Preferably, the wire feeding mechanism includes a slide rail, an electric slider, a first electric telescopic rod, and a wire feeder. The slide rail is welded to the center of the top of the base, and the electric slider is slidably connected to the top of the slide rail. The top of the electric slider is fixedly connected to one end of the first electric telescopic rod, and the wire feeder is fixedly connected to the other end of the first electric telescopic rod.

[0010] Preferably, the winding mechanism includes a bracket, a rotary motor, a rotating rod, a shaped rod, a first limiting plate, a second limiting plate, a rotating seat, a rotating shaft, a pressure block, a spring, a second electric telescopic rod, a slide groove, a connecting rod, and a support plate. A bracket is welded to the other side of the top of the base. A rotary motor is fixedly connected to the rear end of the bracket. A rotating rod is fixedly connected to the output end of the rotary motor. A shaped rod is welded to the front of the rotating rod. A first limiting plate is threaded to the outer side of the rotating rod. A second limiting plate is movably connected to the front end of the shaped rod.

[0011] Preferably, a rotating seat is welded to the front end of the second limiting plate, the pressure block is hinged to the rotating seat via a rotating shaft, one end of the rotating shaft is fixedly connected to a spring, and the other end of the spring is fixedly connected to the rotating seat.

[0012] Preferably, the outer side of the irregular rod is fixedly connected to one end of the second electric telescopic rod, and the other end of the second electric telescopic rod is fixedly connected to a sliding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a second electric telescopic rod, a sliding groove, a connecting rod, and a support plate. The support plate is connected to the sliding groove via the connecting rod and secured with bolts. After the second electric telescopic rod extends, the support plate supports the coil, maintaining the stability of the hollow cup. When the coil needs to be removed, the second electric telescopic rod first retracts the inner-wide, outer-narrow support plate, and then retracts the outer-wide, inner-narrow support plate, preventing the support plate from jamming and affecting the stroke. By setting a rotating rod, a shaped rod, a first limiting plate, and a second limiting plate, the first and second limiting plates cooperate to limit the winding width and prevent detachment. By setting a rotating seat, a rotating shaft, a pressure block, and a spring, the pressure block contacts the shaped rod, preventing the second limiting plate from loosening during winding. When the second limiting plate is moved, the pressure block is lifted and rotated on the rotating seat, while the spring is stressed. After releasing, the spring returns to its original position, allowing the pressure block and the shaped rod to re-contact and maintain stability.

[0015] This invention features a central shaft, bearings, and a tray. Raw materials are placed on the tray, and when the winding mechanism is working, pulling the raw materials causes the tray to rotate. The bearings reduce friction when the tray rotates. The conical frame facilitates fixing the position of the raw materials and makes it easy to place them on the tray. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides an embodiment of a hollow cup motor coil winding device, comprising a base 1, a raw material placement mechanism 3, a wire feeding mechanism 4, and a winding mechanism 5. A controller 2 is provided on the front of the base 1, the raw material placement mechanism 3 is installed on one side of the top of the base 1, the wire feeding mechanism 4 is installed at the center of the top of the base 1, and the winding mechanism 5 is installed on the other side of the top of the base 1.

[0027] Specifically, the raw material placement mechanism 3 includes a central shaft 301, a bearing 302, a tray 303, and a conical frame 304. The central shaft 301 is welded to one side of the top of the base 1. The bearing 302 is sleeved on the outside of the central shaft 301. The tray 303 is sleeved on the outside of the bearing 302. When the raw material is placed on the tray 303, the tray 303 can be rotated by pulling the raw material. The bearing 302 can reduce the friction when the tray 303 rotates.

[0028] Specifically, a conical frame 304 is welded to the top of the tray 303. The size of the conical frame 304 is smaller than that of the tray 303. The conical frame 304 is convenient for fixing the position of the raw materials and also makes it easy to place the raw materials on the tray 303.

[0029] Specifically, the wire feeding mechanism 4 includes a slide rail 401, an electric slider 402, a first electric telescopic rod 403, and a wire feeder 404. The slide rail 401 is welded to the center of the top of the base 1. The electric slider 402 is slidably connected to the top of the slide rail 401. The top of the electric slider 402 is fixedly connected to one end of the first electric telescopic rod 403. The other end of the first electric telescopic rod 403 is fixedly connected to the wire feeder 404. The electric slider 402 moves on the slide rail 401, and at the same time the first electric telescopic rod 403 extends and retracts, which can change the position of the wire feeder 404.

[0030] Specifically, the winding mechanism 5 includes a bracket 501, a rotary motor 502, a rotating rod 503, a shaped rod 504, a first limiting plate 505, a second limiting plate 506, a rotating seat 507, a rotating shaft 508, a pressure block 509, a spring 510, a second electric telescopic rod 511, a slide groove 512, a connecting rod 513, and a support plate 514. The bracket 501 is welded to the other side of the top of the base 1, and the rotary motor 502 is fixedly connected to the rear end of the bracket 501. A rotating rod 503 is fixedly connected to the output end of motor 502. A shaped rod 504 is welded to the front of the rotating rod 503. A first limiting plate 505 is threaded to the outer side of the rotating rod 503. A second limiting plate 506 is movably connected to the front end of the shaped rod 504. When the rotating motor 502 works, it drives the rotating rod 503 and the shaped rod 504 to rotate, causing the wire to wind up. The first limiting plate 505 and the second limiting plate 506 cooperate to limit the width of the winding and prevent it from coming off the position.

[0031] Specifically, a rotating seat 507 is welded to the front end of the second limiting plate 506. The pressure block 509 is hinged to the rotating seat 507 via a rotating shaft 508. The outer side of the rotating shaft 508 is fixedly connected to one end of the spring 510, and the other end of the spring 510 is fixedly connected to the rotating seat 507. The pressure block 509 and the irregular rod 504 are in contact, which can prevent the second limiting plate 506 from coming loose during winding. When the second limiting plate 506 is moved, the pressure block 509 is lifted and rotated on the rotating seat 507. At the same time, the spring 510 is stressed. After releasing, the spring 510 returns to its original position, so that the pressure block 509 and the irregular rod 504 can re-contact and maintain stability.

[0032] Specifically, the outer side of the irregular rod 504 is fixedly connected to one end of the second electric telescopic rod 511, and the other end of the second electric telescopic rod 511 is fixedly connected to a slide groove 512. A connecting rod 513 is slidably connected inside the slide groove 512, and a support plate 514 is welded to the outer side of the connecting rod 513. The support plate 514 is bolted to the slide groove 512. The support plate 514 has two shapes: the first type is wider on the outside and narrower on the inside, and the second type is wider on the inside and narrower on the outside. The support plate 514 is connected to the slide groove 512 through the connecting rod 513 and then fixed with bolts. After the second electric telescopic rod 511 extends, the support plate 514 supports the coil and keeps the hollow cup stable. When the coil needs to be removed, the second electric telescopic rod 511 first drives the support plate 514 (wider on the inside and narrower on the outside) to retract, and then drives the support plate 514 (wider on the outside and narrower on the inside) to retract, so as to avoid the support plate 514 getting stuck and affecting the stroke.

[0033] Working principle: First, the raw material is placed on the tray 303. When the winding mechanism 5 is working, pulling the raw material will cause the tray 303 to rotate. The bearing 302 can reduce the friction when the tray 303 rotates. The tapered frame 304 facilitates fixing the position of the raw material and makes it easy to place the raw material on the tray 303. Next, the support plate 514 is connected to the slide groove 512 through the connecting rod 513 and fixed with bolts. After the second electric telescopic rod 511 extends, the support plate 514 supports the coil. Then, the first limiting plate 505 and the second limiting plate 506 cooperate to limit the winding width and prevent it from falling out of position. The pressure block 509 contacts the shaped rod 504 to prevent the second limiting plate 506 from loosening during winding. When the second limiting plate 506 is moved, the pressure block 509 is lifted and rotated on the rotating seat 507. At the same time, the spring 510 is stressed. After releasing, the spring 510 returns to its original position, so that the pressure block 509 and the irregular rod 504 can re-contact and maintain stability. Then, the rotary motor 502 works, driving the rotating rod 503 and the irregular rod 504 to rotate, so that the wire is wound up. At the same time, the electric slider 402 moves on the slide rail 401, and the first electric telescopic rod 403 extends and retracts, which can change the position of the wire feeder 404. When it is necessary to remove the coil, the second electric telescopic rod 511 first drives the inner wide and outer narrow support plate 514 to retract, and then drives the outer wide and inner narrow support plate 514 to retract, so as to avoid the support plate 514 getting stuck and affecting the stroke.
