Description

Technical Field

[0001] This invention belongs to the field of automatic production equipment for hollow cup motor rotors, and more specifically, relates to an automatic coiling device for an automated production line for hollow cup motor rotors. Background Technology

[0002] With the development of technology and the rise in labor costs, production automation has become increasingly suitable for the current situation, and replacing manual production with fully automated production lines has become the choice of more and more manufacturing companies.

[0003] Coreless motors are widely used in military, aerospace, civilian electrical appliances, and industrial products due to their outstanding characteristics such as high energy conversion efficiency, rapid starting and braking, stable and reliable operation, and small speed fluctuation.

[0004] The conventional structure of a hollow cup motor rotor includes a spool, a rotor frame, a rotor shaft, and a commutator. The rotor frame is fixedly mounted on the rotor shaft, the commutator is mounted on the rotor frame, the spool covers the rotor frame, and the circumferentially distributed coil of wire on the spool is pressed together with the circumferentially distributed coil of commutator segments.

[0005] In the prior art, before pressing the wire ends of the spool in the hollow spool motor rotor and the commutator segments, the wire ends of the spool are mostly upright or slightly deflected at an angle relative to upright, that is, roughly parallel to the axis of the spool. The top surface of the commutator is horizontal. Therefore, the wire ends need to be pressed down to a roughly horizontal position to be close to the top surface of the commutator. In the prior art, the wire ends are usually pressed down manually on the operating table before pressing, which requires specially assigned personnel and is time-consuming and labor-intensive. Summary of the Invention

[0006] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an automatic wire coiling device for an automated production line of a coreless motor rotor. This device uses a pressure head to press down the wire ends on the coreless motor rotor, and then the rotating base's carrier positioning block drives the carrier to rotate, thereby sequentially pressing a ring of wire ends from the coil onto the commutator. It is suitable for use on production lines and easily enables automated production.

[0007] To achieve the above objectives, according to the present invention, an automatic coiling device for an automated production line of a hollow cup motor rotor is provided, characterized in that it includes a rotating base and a pressing device, wherein:

The rotating shaft and the push rod are coaxially arranged, and the push rod is movably inserted inside the rotating shaft. The cylinder is fixedly connected to the lower end of the push rod to drive the push rod to move up and down, so that when the push rod moves upward, the top end of the push rod cooperates with the top plate of the carrier positioning block to clamp the carrier, and when the push rod moves downward, it releases the clamping of the carrier;

[0009] The wire pressing device includes a pressing head drive cylinder and a pressing head. The pressing head is connected to the pressing head drive cylinder to drive the pressing head to move horizontally, thereby pressing down the upright wire end on the spool of the hollow cup motor rotor on the carrier.

[0010] Preferably, the end face of the pressure head used to contact the wire end is an arc surface, and arc transition angles are respectively provided at the upper and lower edges of the arc surface.

[0011] Preferably, a stop bar is provided along the length of the guide rail to block the carrier conveyed onto the guide rail by an external conveying mechanism.

[0012] Preferably, the top plate is provided with a guide groove, which is parallel to the guide rail, so that the vehicle moves along the guide groove onto the vehicle positioning block.

[0013] Preferably, the carrier is provided with two mutually planar first guide surfaces, and correspondingly, the inner wall of the carrier positioning block is also provided with two mutually parallel second guide surfaces, each of the second guide surfaces being respectively attached to one of the first guide surfaces.

[0014] Preferably, the rotating base further includes an encoder, a photoelectric sensor, and a sensing element. The encoder is connected to the output shaft of the motor, and the photoelectric sensor and the sensing element are respectively mounted on the mounting platform and the rotating shaft to obtain the rotational position of the rotating shaft.

[0015] Preferably, the rotating shaft is mounted on the mounting platform via a bearing, and an external thread is provided on the outer side wall of the rotating shaft. A lock nut is connected to the external thread of the rotating shaft, thereby locking the rotating shaft onto the inner ring of the bearing.

[0016] Preferably, the guide rail is provided with a receiving hole, and the carrier positioning block is located at the receiving hole.

[0017] Preferably, the plane of the base plate for supporting the vehicle is coplanar with the plane of the guide rail for supporting the vehicle.

[0018] Preferably, a guide groove is arranged along the entire length of the top plate, and the guide groove is parallel to the guide rail;

[0019] The material-pushing block has two material-pushing grooves, and these two material-pushing grooves are arranged along the length of the guide rail, so as to simultaneously push one of the vehicles into the vehicle positioning block and push the other vehicle out of the vehicle positioning block.

[0020] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0021] 1) An automatic coiling device for an automated production line of a hollow cup motor rotor according to the present invention, wherein the motor can drive the rotating shaft and the carrier positioning block on the rotating shaft to rotate, thereby causing the carrier mounted on the carrier positioning block and the hollow cup motor rotor mounted on the carrier to rotate, so that the pressing device located next to the rotating base can automatically press the wire ends on the spool of the hollow cup motor rotor, thereby helping to realize the automation of pressing.

[0022] 2) An automatic coiling device for an automated production line of a hollow cup motor rotor according to the present invention, wherein the push rod can extend into the carrier positioning block from the through hole on the bottom plate of the carrier positioning block to hold the carrier in place, thereby cooperating with the top plate of the carrier positioning block to fix the carrier, preventing the carrier from being misaligned radially along the rotating shaft when the rotating shaft drives the carrier positioning block to rotate, which would affect the normal coiling of the hollow cup motor rotor by the coiling device above the rotating base.

[0023] 3) An automatic coiling device for an automated production line of a hollow cup motor rotor according to the present invention, wherein the feeding block can move under the drive of a multi-axis motion platform, allowing the carrier to enter the feeding groove, thereby feeding the carrier into the carrier positioning block to realize the installation of the carrier, which facilitates the pressing device above the rotating base to perform the pressing work.

[0024] 4) The present invention provides an automatic coiling device for an automated production line of a hollow cup motor rotor. The entire process is fully mechanical and automatic, driving the carrier and the hollow cup motor rotor mounted on the carrier to rotate. In conjunction with the coiling device above the rotating base, the device sequentially coils the wire ends on the coil spool of the hollow cup motor rotor and the commutator segments. No manual operation is required, which greatly liberates productivity, improves production efficiency, and effectively eliminates the risks of burns caused by manual operation.

[0025] 5) The rounded surface and transition angle of the pressure head end face are designed to ensure the wire end fits perfectly in the middle of the commutator segment, preventing misalignment and facilitating the next welding step, reducing incomplete welds, and improving yield. The rounded surface essentially forms a groove, which avoids the protective sleeve on the rotor shaft of the hollow cup motor rotor (the protective sleeve prevents weld slag from falling into the commutator and causing defects) during the wire pressing process, thus preventing damage to the protective sleeve during wire winding.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Reference Figures 1-6 An automatic coiling device for an automated production line of a hollow cup motor rotor includes a rotating base 200 and a pressing device 100, wherein:

[0033] The rotating base 200 includes a mounting platform 35, a guide rail 48, a cylinder 18, a motor 37, a rotating shaft 54, a push rod 56, a carrier positioning block 42, and a material feeding device, wherein:

[0034] The guide rail 48 is horizontally mounted on the mounting platform 35 to guide the movement of the carrier 15 for mounting the hollow cup motor rotor. It is preferably mounted on the mounting platform 35 via a mounting base 49, and a stop bar 47 is provided along the length of the guide rail 48 to block the carrier 15 for mounting the hollow cup motor rotor, which is conveyed to the guide rail 48 by an external conveying mechanism. The carrier 15 acts as a tool for mounting and assembling the hollow cup motor rotor. The external conveying mechanism can be a conveyor belt or a robotic arm. If it is a conveyor belt, the conveyor belt is perpendicular to the guide rail 48, conveying the foremost carrier 15 onto the guide rail 48 in a direction perpendicular to the guide rail 48. Because the foremost carrier 15 is blocked by the stop bar 47, subsequent carriers 15 queue on the conveying mechanism, waiting for the foremost carrier 15 to be delivered before being conveyed onto the guide rail 48 in sequence.

[0035] The motor 37 and the cylinder 18 are respectively mounted on the mounting platform 35. The rotating shaft 54 ​​is vertically arranged and rotatably mounted on the mounting platform 35. The motor 37 is connected to the rotating shaft 54.

[0036] The carrier positioning block 42 is installed at the top of the rotating shaft 54. The carrier positioning block 42 has an inner cavity and includes a top block 421, a side connecting block 422 and a bottom block 423 for receiving the carrier 15. The side connecting block 422 connects the top block 421 and the bottom block 423. The bottom block 423 is provided with a through hole as a moving channel for the top rod.

[0037] The feeding device includes a feeding block 8 and a multi-axis motion platform. The feeding block 8 is mounted on the multi-axis motion platform and has feeding grooves to feed the carrier 15 on the guide rail 48. This allows the carrier 15 to extend into the inner cavity of the carrier positioning block 42 and be supported by the bottom block 423 of the carrier positioning block 42. The carrier 15 can then be placed on the bottom block 423 of the carrier positioning block 42. Preferably, the base 44 of the carrier 15 enters the inner cavity of the carrier positioning block 42.

[0038] There are many structural forms for the carrier 15, as long as it can support the hollow cup motor rotor. After the hollow cup motor rotor, which consists of coil, rotor frame and commutator 45, is placed on the carrier 15, the soldering device above the rotating base 200 can perform soldering operations on the hollow cup motor rotor.

[0039] The rotating shaft 54 ​​has a through hole running vertically through it. The rotating shaft 54 ​​and the push rod 56 are coaxially arranged, and the push rod 56 is movably inserted through the interior of the rotating shaft 54. That is, the rotating shaft 54 ​​and the push rod 56 are not fixed together, but are independent of each other, and can rotate and move relative to each other. The cylinder 18 is fixedly connected to the lower end of the push rod 56 to drive the push rod 56 to move up and down. This facilitates the top end of the push rod 56 to engage with the top block 421 of the carrier positioning block 42 to clamp the carrier 15 when the push rod 56 moves upward, and facilitates the release of the clamp on the carrier 15 when the push rod 56 moves downward. Preferably, the lower end of the push rod 56 extends beyond the lower end of the rotating shaft 54 ​​to facilitate the connection between the cylinder 18 and the push rod 56. When the push rod 56 moves upward, it presses the carrier 15 onto the top block 421, preventing the carrier 15 from moving. This way, when the rotating shaft 54 ​​drives the carrier positioning block 42 and the carrier 15 to rotate together, the carrier 15 will not shift, thus not affecting the soldering work of the soldering device above the rotating base 200 on the hollow cup motor rotor.

[0040] Furthermore, the cylinder 18 has a push rod 19, which is connected to the push rod 56 via a push rod connector 57. The push rod 19 pushes upward to drive the push rod 56 to move upward. The cylinder 18 is fixedly mounted on the mounting platform 35 via a mounting block.

[0041] Furthermore, the top block 421 is provided with a guide groove 4211, which is parallel to the guide rail 48, so that the carrier 15 moves along the guide groove 4211 onto the carrier positioning block 42. If a part of the carrier 15 extends upward beyond the top block 421, the guide groove 4211 can adapt well to the shape of the carrier 15, allowing the carrier 15 to still enter the inner cavity of the carrier positioning block 42.

[0042] Furthermore, the carrier 15 is provided with two mutually planar first guide surfaces, and correspondingly, the inner wall of the carrier positioning block 42 is also provided with two mutually parallel second guide surfaces, each of which is in contact with one of the first guide surfaces. If the carrier 15 and the carrier positioning block 42 have cylindrical structures, the portions of the first and second guide surfaces will form flat structures, allowing the two guide surfaces to fit together well. This also prevents the carrier 15 from having rotational displacement when the carrier positioning block 42 drives the carrier 15 to rotate, which would affect the normal soldering of the hollow cup motor rotor by the soldering device.

[0043] Furthermore, the motor 37 is connected to the rotating shaft 54 ​​via a gear mechanism, which includes a driving gear 16 and a driven gear 17. The driving gear 16 and the driven gear 17 mesh with each other, so the driving gear 16 is mounted on the output shaft of the motor 37, and the driven gear 17 is fixedly mounted on the rotating shaft 54. The driven gear 17 drives the rotating shaft 54 ​​to rotate, the rotating shaft 54 ​​drives the carrier positioning block 42 to rotate, the carrier positioning block 42 drives the carrier 15 to rotate, and the carrier 15 drives the spool 14 and the hollow cup motor rotor on the carrier 15 to rotate. The sensing plate 39 is disposed above the driven gear 17.

[0044] Furthermore, the multi-axis moving platform is an XY-axis motion platform, used to drive the material-pulling block 8 to move horizontally in a direction parallel to the guide rail and horizontally in a direction perpendicular to the guide rail. The X-axis of the XY-axis motion platform is parallel to the guide rail 48, and the Y-axis is perpendicular to the guide rail 48. When the material-pulling block 8 moves in a direction perpendicular to the guide rail 48, the material-pulling groove can be locked on the carrier 15. When it moves in a direction parallel to the guide rail 48, it can move the carrier 15, allowing the carrier 15 to move along the length direction of the guide rail 48 to extend into the inner cavity of the carrier positioning block 42.

[0045] Reference Figure 1 The multi-axis motion platform includes a first cylinder 6, a slider, a mounting frame 22, a second slider 20, and a second cylinder 7. A feeding block 8 is fixedly mounted to the mounting frame 22, which in turn is fixedly mounted to the first slider 381. The first slider 381 is pushed by the first cylinder 6, which in turn pushes the first slider 381 back and forth. This back and forth movement of the first slider 381 drives the mounting frame 22, which is fixedly connected to the first slider 381, to move back and forth. The back and forth movement of the mounting frame 22 then drives the feeding block 8 to move back and forth. Meanwhile, the first cylinder 6 is fixedly installed on the second slider 20. The second slider 20 is pushed by the second cylinder 7, which is fixedly installed on the mounting platform 35. The second cylinder 7 pushes the second slider 20 to move left and right, which in turn moves the first cylinder 6 fixedly installed on the second slider 20 to move left and right. At the same time, it drives the feeding block 8 to move left and right, so that the feeding block 8 can achieve functions such as moving forward, right, backward, and left. This moves the carrier 15, which carries the spool 14 and rotor frame that have not yet undergone the welding process, to the bottom of the solder gun for welding operation.

[0046] Furthermore, the rotating base 200 also includes an encoder, a photoelectric sensor 40, and a sensing element 39. The encoder is connected to the output shaft of the motor 37. The photoelectric sensor 40 and the sensing element 39 are respectively mounted on the mounting platform 35 and the rotating shaft 54 ​​to obtain the rotational position of the rotating shaft 54. The encoder can determine the rotation angle of the rotating shaft 54, while the photoelectric sensor 40 and the sensing element 39 work together to determine the initial position of the rotating shaft 54. The encoder, photoelectric sensor 40, and sensing element 39 work together to determine the rotational position of the rotating shaft 54.

[0047] Furthermore, the rotating shaft 54 ​​is mounted on the mounting platform 35 via bearings. The outer wall of the rotating shaft 54 ​​has external threads, and a locking nut 53 is connected to these external threads to lock the rotating shaft 54 ​​onto the inner ring of the bearings, preventing axial vibration during rotation. The rotating shaft 54 ​​is mounted on the mounting platform 35 via two bearings: a first bearing 51 and a second bearing 55. The first bearing 51 is positioned above the second bearing 55, and the locking nut 53 locks the rotating shaft 54 ​​onto the inner ring of the first bearing 51.

[0048] Furthermore, the guide rail 48 is provided with a receiving hole, and the carrier positioning block 42 is located at the receiving hole. The carrier positioning block 42 divides the guide rail 48 into two sections. One section is used to allow the carrier 15 to enter the carrier positioning block 42, and the other section is used to allow the carrier 15, after the welding process is completed, to leave the carrier positioning block 42 and move to the next process.

[0049] Furthermore, the plane of the bottom block 423 that supports the carrier 15 is coplanar with the plane of the guide rail 48 that supports the carrier 15, which facilitates the entry and exit of the carrier 15 on the guide rail 48 from the carrier positioning block 42.

[0050] Furthermore, the guide groove 4211 on the top block 421 is arranged along the entire length, and there are two material feeding grooves on the feeding block 8. These two material feeding grooves are arranged along the length direction of the guide rail 48, so as to simultaneously feed one of the carriers 15 into the carrier positioning block 42 and feed the other carrier 15 out of the carrier positioning block 42.

[0051] The base rotation device is positioned below the solder gun of the soldering device. The motor 37 is preferably a geared motor 37 with a gearbox 36. The drive gear 16 is fixedly mounted on the output shaft of the gearbox 36. An encoder is connected to the motor 37 to form a closed-loop control. The gearbox 36 is fixedly mounted on a flange 41 and then fixedly mounted to the mounting platform 35 via the flange 41. The rotating shaft 54 ​​is fixedly mounted on the mounting platform 35 via bearings. Several support columns 34 are provided around the mounting platform 35 for mounting to the production line table.

[0052] A locking nut 53 is installed above the induction plate 39. A bearing and a bearing support ring 50 are installed at the upper end of the locking nut 53. Both the bearing and the bearing support ring 50 are located inside the bearing mounting seat 52, which is mounted on the mounting platform 35. A carrier positioning block 42 is located at the upper end of the rotating shaft 54 ​​and is fixedly installed with the rotating shaft 54. The spool 14 and the rotor of the hollow cup motor 37 are simultaneously mounted on the carrier 15. A protective sleeve 13 is fitted on the outer side of the rotor shaft 43 of the hollow cup motor 37. The protective sleeve 13 is used to protect the commutator 45 from solder balls and rosin splashing into the slot of the commutator 45 during high-temperature soldering, thus preventing the generation of defective products.

[0053] The wire pressing device 100 includes a pressing head drive cylinder 2 and a pressing head 5. The pressing head drive cylinder 2 is mounted on the mounting platform 35 or the base 1, and the pressing head 5 is connected to the pressing head drive cylinder 2 to drive the pressing head 5 to move horizontally, thereby pressing down the upright wire ends on the spool of the hollow cup motor rotor on the carrier (initially, part of the wire end on the spool is upright, and another part is deflected inward or outward at a certain angle relative to the upright position, and needs to be pressed down to a roughly horizontal position, close to the commutator, in order to achieve welding of the wire end to the commutator). The pressing head drive cylinder 2 is preferably a slider cylinder, and a mounting block 4 is connected to its slider 3, preferably connected to the pressing head 5 through the mounting block. Two wire pressing devices 100 can be set up simultaneously, symmetrically arranged on both sides of the spool 14, which can improve work efficiency.

[0054] The end face of the pressure head 5 that contacts the end of the wire is an arc surface 52, and the upper and lower edges of the arc surface 52 are respectively provided with arc transition angles, namely upper arc transition angle 53 and lower arc transition angle 51. The upper arc transition angle 53 can contact the upright wire 141 that is deflected outward at a certain angle, and the lower arc transition angle 51 can contact the upright wire 141 that is deflected inward at a certain angle. Then the pressure head 5 moves horizontally to press the wire 141 to a roughly horizontal state.

[0055] The working process of this invention is as follows:

[0056] 1)Reference Figure 1 , Figure 4The first cylinder 6 pushes the first slider 381 forward, causing the material-pulling block 8, which is mounted with the first slider 381, to move to the left. The material-pulling groove on the material-pulling block 8 is engaged with the carrier 15. Then, the second cylinder 7 pushes the second slider 20 forward. The movement of the second slider 20 causes the material-pulling block 8 to move forward, which in turn causes the carrier 15 to move forward as well. The flat part of the carrier 15 is inserted into the carrier positioning block 42. At the same time, the cylinder pushes the push rod 19 upward. The push rod 19 pushes the top rod 56 through the connector 57, causing the top rod 56 to move upward and hold the carrier 15 in place. The top rod 56 and the top block 421 of the carrier positioning block 42 together clamp the carrier 15, fixing the carrier 15 inside the carrier positioning block 42. At the same time, the material-pulling block 8 retracts to the right and then moves backward, returning to its initial position.

[0057] 2) The pressing heads 5 of the left and right pressing devices 100 move horizontally at the same time, pressing down the two wire ends 141 on the spool 14 to the position close to the commutator.

[0058] 3) The pair of solder guns of the soldering device above the rotating base move downwards first. After the solder guns are powered on, they solder the two wire ends 141 in the spool 14 to the commutator 45 (the commutator 45 has been previously soldered). After the soldering is completed, the pair of solder guns of the soldering device above the rotating base 200 retract upwards.

[0059] 4) The motor 37 drives the drive gear 16 to rotate, which in turn drives the driven gear 17 meshing with the drive gear 16 to rotate. The rotation of the driven gear 17 drives the rotating shaft 54, which is fixedly installed with the driven gear 17, to rotate. The rotation of the rotating shaft 54 ​​drives the sensing plate 39 installed on the rotating shaft 54 ​​to rotate by a set angle, and at the same time drives the carrier positioning block 42 to rotate by a set angle. The carrier positioning block 42 drives the carrier 15 to rotate by a set angle. The set angle of rotation of the rotating shaft 54 ​​is determined by the sensing plate 39 and the photoelectric sensor 40.

[0060] 5) If the number of wire ends 141 is even, repeat steps 2), 3) and 4) above until all wire ends 141 are soldered to the commutator 45.

[0061] If the number of wire ends 141 is odd, when only one wire end 141 remains unsoldered, the pressure head on one side moves next, and the solder gun on one side moves downward, so that the last wire end 141 of the spool 14 is soldered to the commutator 45. In this way, all wire ends 141 are soldered to the commutator 45.

[0062] After welding is completed, push rod 19 falls back, pulling push rod 56 back down. Push rod 56 releases its clamp on carrier 15, allowing material-pulling block 8 to smoothly pull carrier 15 off carrier positioning block 42, so that carrier positioning block 42, along with carrier and the hollow cup motor rotor mounted on the carrier, can enter the next process.

[0063] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
