Description

Technical Field

[0001] This invention belongs to the field of hollow cup processing equipment, and more specifically, relates to a modular cup forming device. Background Technology

[0002] Hollow cup motors use a hollow cup as the rotor, eliminating the energy loss caused by eddy currents formed in the iron core. At the same time, their weight and moment of inertia are greatly reduced, reducing the mechanical energy loss of the rotor itself. The energy density of motors using hollow cups is greatly improved. Compared with motors with iron cores of the same power, their weight and volume are greatly reduced, making them a highly efficient energy conversion mechanism.

[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] Because of the precision design of coreless motors, which involve numerous components, especially the core itself, the accuracy requirements are very high. The diamond-shaped coil serves as the basic unit of the coreless motor. These coils are stacked together and then hot-pressed to form a composite coil. This composite coil is then rounded to form a cup-shaped composite coil. The composite coil then undergoes a series of processes including cold pressing, rounding, and tinning to create the final coreless motor that can be used in coreless motors.

[0005] Because the hollow cup motor is designed with precision and has many parts, especially the precision requirements of the spliced ​​spool, manual assembly is not only complicated and cannot guarantee its roundness, but also has low production efficiency. Summary of the Invention

[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 1-5A modular spool forming device includes a base 7 and a rounding module mounted on the base 7. The rounding module includes a first forming fixture and a plurality of first pressing rounding components arranged around the first forming fixture, wherein:

[0033] The first forming fixture includes a first fixed post 10, a first rotating shaft 32, a first push rod 31, a first round bar 11, a first positioning sleeve 24, a first drive motor 41, and a first lifting drive mechanism A49. The first fixed post 10 has a first through hole extending vertically and is fixedly mounted on the base 7. The first rotating shaft 32, the first push rod 31, and the first round bar 11 are coaxially arranged and are all vertically arranged. The upper end of the first rotating shaft 32 is mounted on the inner wall of the first fixed post 10 via a bearing A30. The first rotating shaft 32 is movably mounted on the first push rod 31. The first rotating shaft 32 and the first push rod 31 each have a limiting structure A and a limiting structure B to restrict the relative rotation of the first push rod 31 and the first rotating shaft 32. The limiting structure A and the limiting structure B can be a boss 26 and a groove, respectively. The first rotating shaft 32 has two planes; for example, the first push rod 31 is a D-shaped shaft and the through hole of the first rotating shaft 32 is a D-shaped hole, or the first push rod 31 is a square rod. These structures can restrict their relative rotation while allowing them to slide relative to each other. The top end of the first push rod 31 is fixedly connected to the first round rod 11. The top end of the first fixed column 10 is fitted with the first positioning sleeve 24 at the position corresponding to the first through hole, and the top surface of the first positioning sleeve 24 is a horizontal receiving surface for receiving the mosaic strip. The first positioning sleeve 24 has a second through hole that serves as a lifting channel for the first round rod 11. The output shaft of the first drive motor 41 is connected to the first rotating shaft 32. The output shaft of the first lifting drive mechanism A49 is connected to the first push rod 31 to drive the first push rod 31 to rise and fall. The first push rod 31 and the output shaft of the first lifting drive mechanism A49 are rotatably connected. The first rotating shaft 32 is locked to the bearing B33 by the first rotating shaft 32 locking nut 34.

[0034] Each of the first pressing round components includes a first pressing block 1 and a first pressing block driving mechanism 3. The first pressing block 1 is mounted on the first pressing block driving mechanism 3 to drive the first pressing block 1 to move horizontally to press the patchwork line cake onto the first round bar 11 and deform the patchwork line cake. The first pressing blocks 1 of each of the first pressing round components cooperate with each other to gradually deform the patchwork line cake into the patchwork line cup 9.

[0035] The pressing block drive mechanism and lifting drive mechanism described in this invention can adopt a cylinder or a structure with a motor connected to a lead screw.

[0036] The process involves stacking multiple rhomboid coils in a staggered manner to form a rhomboid coil group, which is supported by a carrier. Each rhomboid coil has two wire ends. After being hot-pressed by a hot-pressing mechanism, the rhomboid coil group forms an integral piece of wire cake. The piece of wire cake is then shaped into a cup-shaped piece of wire cup, which includes processes such as rounding and rounding.

[0037] Furthermore, the first push rod 31 and the first round rod 11 each have a vertical third through hole and a vertical fourth through hole, and the inner wall of the first push rod 31 and the inner wall of the first round rod 11 are connected by the outer ring of the bearing B33. The rounding module of the present invention also includes a heating component. The third and fourth through holes facilitate the installation of the heating component. The heating component includes a heating tube A28 and a heating tube sleeve A29 fixedly mounted on the heating tube A28. The heating tube sleeve A29 is placed on the inner ring of the bearing B33. The upper end of the heating tube A28 extends into the fourth through hole of the first round rod 11 for heating the first round rod 11, and the lower end of the heating tube A28 protrudes from the lower end of the first push rod 31. In addition, each of the first pressing blocks 1 is equipped with a heating device for heating the first pressing block 1. With the above settings, the spool 9 of the assembly block can be heated internally and externally. The lower end of the heating tube sleeve A29 can extend into the inner ring of the bearing B33 and the two are interference-fitted. The bearing B33 is designed so that the heating component and the first round bar 11, the first rotating shaft 32, and the first push rod 31 can rotate relative to each other. The rotation of the first round bar 11, the first rotating shaft 32, and the first push rod 31 does not affect the normal operation of the heating component.

[0038] Furthermore, the system also includes a robotic arm, a lifting drive mechanism B22, a support, a pneumatic gripper, a compression spring, and a guide post 21. The robotic arm is mounted on the base 7 via a running track. The lifting drive mechanism B22 is mounted on the robotic arm, and the support is mounted on the output shaft of the lifting drive mechanism B22 to drive the support to move up and down. The pneumatic gripper is mounted on the support, and the pneumatic gripper includes a cylinder body and two gripping fingers 20 driven by the cylinder body for gripping the spool 9. The guide post 21 is vertically arranged and located between the two gripping fingers 20. The guide post 21 is slidably mounted on the support so that it can be moved up and down to adjust its position so that the spool 9 can be fitted onto the guide post 21 or separated from the guide post 21. The upper end of the compression spring is connected to the support, and the lower end is connected to the guide post 21. The compression spring can act as a buffer and allows the guide post 21 to have a certain upward stroke, making it easy for the guide post 21 to retract from the spool 9.

[0039] Furthermore, the present invention also includes a twisting device for twisting the two ends of the spool 9 into one strand and a cutting device 15 for cutting the ends of the strand to a set length, both of which are mounted on the robotic arm. The twisting device and the cutting device 15 can employ existing structures.

[0040] Furthermore, a connecting seat 40 is fixedly installed on the output shaft of the first lifting drive mechanism A49. An annular notch is provided at the lower end of the first push rod 31, and a slot is provided on the connecting seat 40. The slot engages with the annular notch of the first push rod 31, thereby achieving a rotatable connection between the first push rod 31 and the output shaft of the first lifting drive mechanism A49. A planar bearing 39 is mounted on the first push rod 31, located above the annular notch. The planar bearing 39 includes a lower cover, a rolling element, and an upper cover. The rolling element is located between the upper and lower covers. The lower cover presses against the connecting seat 40. The upper cover is interference-fitted with the first push rod 31, and the lower cover is clearance-fitted with the first push rod 31. The lifting drive mechanism B22 uses a cylinder, which is equipped with a push-pull rod 46. A push-pull plate 48 is installed on the top of the push-pull rod 46, and a connecting seat 40 is installed at the front end of the push-pull plate 48. The connecting seat 40 can be locked onto the annular slot at the bottom of the first push rod 31. Driven by the first lifting drive mechanism A49, the push-pull rod 46 is pushed up and down, which in turn drives the push-pull plate 48 to move up and down. When the push-pull plate 48 moves upward, it pushes the plane bearing 39 installed on the first push rod 31. The plane bearing 39 causes the first push rod 31 to move upward, which in turn pushes the first round bar 11 installed on the first push rod 31 to move upward. When the push-pull rod 46 moves downward, it drives the push-pull plate 48 to move downward. Through the connecting seat 40, the first push rod 31 is pulled downward, which in turn pulls the first round bar 11 downward.

[0041] Furthermore, the present invention also includes a rounding module installed on the base 7. The rounding module includes a second forming fixture and a plurality of second rounding components arranged around the first forming fixture. The second forming fixture has the same structure as the first forming fixture. Each second rounding component includes a second pressing block driving mechanism and a second pressing block 18 installed on the second pressing block driving mechanism. The second pressing block 18 is provided with an arc surface with the same diameter as the outer circular surface of the splice spool 9.

[0042] For the rounding module of the present invention, the first rounding component is preferably provided with six. The first pressing block driving mechanism 3 adopts a cylinder. Six first pressing block driving mechanisms and first fixed seats 5 are evenly arranged around the first fixed column 10. Each first fixed seat 5 is provided with a first pressing block 1. A first push rod 4 is provided between the output shaft of the first pressing block driving mechanism 3 and the pressing block. Two heating tubes B2 are installed on each first pressing block 1. The base 7 is below the driving component for driving the rotation and lifting of the first round rod 11. The first fixed column 10 has a first through hole inside and a first boss 26 in the middle. The first boss 26 is provided with a first mounting hole 27. The first fixed column 10 is fixedly installed in the first through hole of the base 7 by installing pins or screws 25. The upper part of the first boss 26 of the first fixed column 10 is above the top surface of the base 7, and the lower part of the boss 26 is located below the top surface of the base 7. A first gearbox 42 is mounted on the front end of the first drive motor 41. The first gearbox 42 is mounted on a flange, which is installed below the mounting platform 38. Four mounting posts 37 are arranged around the mounting platform 38, and the mounting platform 38 is fixedly connected to the mounting posts 37. The mounting posts 37 are located below the base 7 and are fixedly connected to the bottom of the base 7. The first drive motor 41 is connected to the input shaft of the first gearbox 42. The output shaft of the first gearbox 42 is equipped with a first driving gear 47, which meshes with a first driven gear 36. The first driven gear 36 is mounted on a first rotating shaft 32. The upper end of the first push rod 31 passes through the top of the first rotating shaft 32 and the boss 26 of the first fixed post 10, reaching the top of the base 7. The top of the first push rod 31 is connected to the lower end of the first round bar 11 through a bearing. A first positioning sleeve 24 is provided on the outside of the first round bar 11, and the first positioning sleeve 24 is fixedly installed above the first fixed post 10 by screws 25. The first positioning sleeve 24 is hollow inside. After the first round rod 11 rises, the upper end of the first round rod 11 can extend from the top of the first positioning sleeve 24. The interior of the first round rod 11 is hollow, and the heating tube sleeve A29 is installed there. The heating tube A28 is installed inside the heating tube sleeve A29. The bottom of the heating tube sleeve A29 is provided with a flange, which rests above the bearing B33 to prevent the heating tube sleeve A29 from falling. The first fixed column 10, the first positioning sleeve 24, the first round rod 11, the first top rod 31, the bearing, the heating tube sleeve A29, the heating tube A28, the mounting platform 38, the first rotating shaft 32, the first driven gear 36, the first sensing plate 35, the first rotating shaft 32, and the locking nut 34 are all coaxially mounted. Furthermore, the output shaft of the first drive motor 41 is connected to an encoder 43; a first sensing plate 35 is installed on the first rotating shaft 32, and a photoelectric sensor 44 for detecting the first sensing plate 35 is installed on the base 7. The photoelectric sensor 44 is installed on the photoelectric sensor mounting plate 45, and the photoelectric sensor mounting plate 45 is fixedly installed on the mounting platform 38.The encoder 43 on the first drive motor 41 works together with the photoelectric sensor 44 to obtain the rotational position of the first rotating shaft 32.

[0043] The rounding module of this invention also has multiple second pressing blocks 18 evenly distributed around the periphery of the second round rod 17. The second pressing blocks 18 are mounted on the second fixed base 19, and a second pressing block driving mechanism 13 is located behind the second fixed base 19. The second pressing block driving mechanism 13 is a booster cylinder. A heating tube B is also provided on the second pressing block 18. The heating tube B heats the second pressing block 18, causing the spool 9 of the assembly piece to deform around the second round rod 17. A driving component is also provided below the second round rod 17, which can drive the second round rod 17 to rotate and move up and down. A temperature controller 12 is also installed on the base 7. The temperature controller 12 has ten displays showing the real-time temperature of the six first pressing blocks 1 of the rounding module, the three second pressing blocks 18 of the rounding module, and the first round rod 11 of the rounding module, so as to control the temperature according to the different materials of the spool 9 and keep the temperature within a stable range. Because the guide post 21 has a compression spring, when it encounters the second round bar 17, the second round bar 17 can push the guide post 21 upwards. The guide post 21 prevents the pneumatic gripper from deforming the spool 9 during the transition from rounding to rounding. A twisting device is installed next to the pneumatic gripper. The twisting device, pneumatic gripper, and guide post 21 are mounted on the same robotic arm. The robotic arm runs on the robotic arm running track 8, transporting the spool 9 from the rounding module to the rounding module. The robotic arm running track 8 is driven and controlled by the robotic arm motor 14. The twisting device includes a twisting motor 23 and a twisting chuck 16. The twisting chuck 16 is driven to rotate by the twisting motor 23. The robotic arm motor 14 controls the up and down movement of the robotic arm. The drive motor, twisting motor 23, and robotic arm motor 14 are all equipped with gearboxes and encoders 43, enabling closed-loop control.

[0044] The working process of this invention is as follows:

[0045] After the invention is powered on, the robotic arm picks up the piece of wire and places it into the alcohol soaking device 6 to soften the surface of the enameled wire. The robotic arm then picks up the alcohol-soaked piece of wire and places it into the first positioning sleeve 24 of the rounding module, so that the piece of wire is placed close to the first round bar 11 of the rounding module. Depending on the position of the piece of wire, the first pressing block 1 has different movement steps. According to the settings, the first pressing block drive mechanism 3 pushes the first pressing block 1 through the push rod, so that the first pressing block 1 moves forward on the movement track of the first fixed seat 5. The first pressing block 1 is provided with two heating tubes B2. The heating tubes B2 heat the first pressing block 1, thereby making the piece of wire soften by heat. After a set sequence, these first pressing blocks 1 repeat the above steps, so that the piece of wire is deformed around the first round bar 11 and connected end to end. Meanwhile, the first round rod 11 is also equipped with a heating tube A28 and a heating tube sleeve A29, so that the piece of wire is heated inside and out during the process of becoming the piece of wire cup 9. This not only makes the piece of wire easier to heat and soften, but also ensures that the temperature difference between the inside and outside of the piece of wire cup 9 is not too large and will affect the quality of the piece of wire cup 9.

[0046] After the modular wire spool becomes the modular wire cup 9, the first drive motor 41 installed below the base 7 rotates, driving the first drive gear 47 installed at the front end of the gearbox to rotate, which in turn drives the first driven gear 36 meshing with the first drive gear 47 to rotate. The rotation of the first driven gear 36 drives the rotation of the first rotating shaft 32, the first sensing plate 35, the first push rod 31, and the first round rod 11. The real-time position of the first round rod 11 can be determined by the photoelectric sensor 44. The first round rod 11 rotates by a set angle, eliminating the problem of uneven heating of the modular wire cup 9 caused by the gap between the first pressure blocks 1, thus improving the quality of the modular wire cup 9. An encoder 43 is installed at the rear end of the first drive motor 41, which can realize closed-loop control, making the control more precise.

[0047] After the spool 9 is rounded, the twisting chuck 16 on the robotic arm, driven by the motor, moves the pneumatic gripper and guide post 21 downwards together. After reaching the set position, the twisting motor 23 drives the twisting chuck 16 to rotate, forming the spool 9 from the spool. The two strands of enameled wire at the beginning and end are then twisted together into one. After the twisting is completed, the wire cutting device 15 cuts off the excess wire ends according to the settings. Furthermore, the pneumatic gripper and guide post 21 on the robotic arm move downwards under the drive of the motor. When the guide post 21 contacts the first round bar 11 of the rounding module, the sensor detects the contact, and the controller controls the second lifting drive mechanism B22 installed at the lower end of the base 7 to pull the push-pull rod 46, causing the connecting seat 40 at the front end of the push-pull plate 48 to move downwards, thereby driving the first push rod 31 to move downwards. The downward movement of the first push rod 31 drives the first round bar 11, which is connected to the first push rod 31 through the outer ring of the bearing B33, to move downwards, thereby driving the heating tube sleeve A29 and the heating tube A28 to move downwards. During the downward movement of the first round bar 11, the guide post 21 moves downwards at the same time, so that the spool 9 of the assembly block is smoothly inserted from the outside of the first round bar 11 into the outside of the guide post 21. The first round bar 11 descends to a position flush with the first positioning sleeve 24, and the pneumatic gripper clamps the assembly spool 9. Simultaneously, the robotic arm moves upward a certain distance. Then, driven by the robotic arm motor 14, the robotic arm moves to the right on the running track. After the pneumatic gripper removes the assembly spool 9, the second lifting drive mechanism B22 pushes the push-pull rod 46, further pushing the push-pull plate 48 upward, causing the first top rod 31 to move upward, which in turn drives the first round bar 11, which is fixed to the first top rod 31, to move upward and return to its previous position.

[0048] The above process is performed on the rounding module.

[0049] After the pneumatic gripper picks up the modular spool 9, the guide post 21 remains positioned in the middle of the modular spool 9 as an internal support during its movement to prevent deformation from the gripper. When the pneumatic gripper reaches the designated position, the top of the second round bar 17 of the rounding module contacts the bottom of the guide post 21. The pneumatic gripper continues downward, and the compression spring on the guide post 21 is compressed due to the obstruction of the second round bar 17, causing the modular spool 9 to transition from the guide post 21 onto the second round bar 17. Afterward, the robotic arm moves upward, repeating the previous command.

[0050] After the spool 9 is placed into position on the second round bar 17 of the rounding module, the three second pressing blocks 18 reciprocate on the second fixed seat 19 according to the set instructions to round the spool 9. The second forming fixture of the rounding module is the same as the first forming fixture of the rounding module in terms of structure and movement, except that the heating tube A28 and heating tube sleeve A29 are not installed.

[0051] 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.
