Description

Technical Field

[0001] The present application relates to the field of S-winding wave-wound flat wire motor W-pin bending devices, and in particular to a flexible W-pin bending auxiliary device. Background Art

[0002] W-pin copper wire is made of high-purity copper and has good electrical conductivity, thermal conductivity and ductility. In equipment such as motors or transformers, W-pin copper wire usually needs to be bent continuously. On the one hand, it can make the W-pin copper wire match the slot structure inside the motor stator for placing the winding. On the other hand, proper bending of the W-pin copper wire can optimize the electromagnetic induction effect of the winding.

[0003] In the related art, the equipment used to bend the W-pin copper wire usually includes a rotary bending mechanism and a cylinder-driven bending mechanism. Taking the rotary bending mechanism as an example, an automatic copper wire bending device with the authorization announcement number CN222113362U includes a frame, a base, a clamping part, a reference component, a rotating part and a clamping manipulator. The copper wire is passed through the clamping part and the bending gap, and the rotating part is rotated along the circumference of the reference component to bend the copper wire. The clamping manipulator then drives the copper wire to move forward for a second time in the bending gap and repeats the bending operation, thereby completing the continuous bending process of the copper wire.

[0004] With regard to the above-mentioned related technologies, the clamping part can only fix the copper wire from both sides. This fixing method cannot effectively limit the freedom of the copper wire in the axial direction when it is radially bent. When the rotating part starts to rotate and bend, due to the insufficient axial component of the clamping force and the lack of targeted anti-rotation settings, the copper wire will produce axial torsion due to the uneven radial force. As a result, the motor winding cannot be accurately embedded in the stator slot or the connection method is wrong, affecting the performance of the motor. Summary of the invention

[0005] In order to improve the problem that the W-pin copper wire is prone to axial torsion when being bent, the present application provides a flexible W-pin bending auxiliary device.

[0006] A flexible W-pin bending auxiliary device provided in this application adopts the following technical solution:

[0007] A flexible W-pin bending auxiliary device, comprising a feeding mechanism for conveying unbent W-pins, a bending fixing seat for fixing the W-pins, a bending mechanism for bending the W-pins, a synchronous conveying mechanism for conveying the bent W-pins, a shearing mechanism for cutting the W-pins, and a frame body for mounting the mechanisms;

[0008] The bending mechanism includes a bending flange, a cam bearing follower, a bending motor, a planetary reducer and a lifting screw slide, wherein the lifting screw slide is fixedly connected to one side of the frame body, and the lifting screw slide is slidably installed with a bending motor seat in the height direction, the bending motor and the planetary reducer are both installed on the upper side of the bending motor seat, the bending flange is installed on the lower side of the bending motor seat, and the cam bearing follower is installed on the lower side of the bending flange;

[0009] The feeding mechanism has a bending fixing seat for the W-pin to pass through, and the end of the bending fixing seat away from the end connected to the frame body is directly opposite to the bottom of the bending flange;

[0010] The synchronous conveying mechanism has a feeding station for the W-pin to enter, and the feeding station is directly opposite to the lower part of the bending flange and the bending fixing seat.

[0011] By adopting the above technical solutions, the lifting screw slide can adjust the height of the bending motor seat, and the cam bearing follower can ensure that the bending angle and curvature of the WPI copper wire are accurate, so that the bent copper wire can perfectly fit the motor stator slot structure and optimize the electromagnetic induction effect of the winding. The feeding mechanism, bending mechanism, synchronous conveying mechanism and shearing mechanism work together to orderly convey the unbent copper wire, accurately bend it, smoothly remove the finished product and cut it off as needed, so as to achieve highly automated continuous bending. Each mechanism is compactly installed on the main body of the frame, the feeding and conveying links are closely connected, and the key bending parts are stable and reliable, ensuring the smooth operation of the W-pin copper wire throughout the entire processing process, reducing shaking and deviation, and improving the bending quality in all aspects.

[0012] Furthermore, the synchronous conveying mechanism includes a rotating seat provided on the frame body and used to rotate synchronously with the bending flange, and a conveying platform provided on the rotating seat and used to receive the bent W-pin;

[0013] The rotating seat includes an annular seat body fixedly connected to the side wall of the frame body, a rotating shaft provided on the annular seat body and a drag chain used to cooperate with the rotating shaft, a sliding guide rail seat provided on the frame body and used to adjust the position of the conveying platform, a seat body driving motor provided below the rotating shaft and rotating synchronously with the bending motor, and a synchronous reducer matched with the seat body driving motor;

[0014] The sliding guide rail seat is located above the annular seat body, and the conveying platform is installed on the sliding guide rail seat.

[0015] By adopting the above technical solution, the rotating seat can rotate synchronously with the bending flange. When the bending mechanism bends the W-pin copper wire, the conveyor table can move in coordination with it. When the bending flange bends the copper wire according to the set angle, the rotating seat drives the conveyor table to rotate synchronously, so that the bent copper wire can be immediately received and follow the rotation of the conveyor table to enter the subsequent process, avoiding problems such as nowhere to receive the copper wire after bending, accumulation or poor conveying connection due to asynchrony, thereby ensuring the continuity and efficiency of the entire W-pin copper wire bending and conveying process.

[0016] Furthermore, the conveyor platform includes a mounting base plate slidably mounted on the sliding guide rail seat, two side plates symmetrically arranged and fixedly connected to the upper side of the mounting base plate, and a synchronous wheel, a synchronous belt and a belt support plate installed between the two side plates.

[0017] By adopting the above technical solution, the installation base plate is slidably installed on the sliding guide rail seat, so that the conveyor platform can accurately adjust its position according to the specific landing point of the W-pin copper wire after bending and the connection requirements of the subsequent processes, so that it is always in the best receiving and conveying state. The two side plates are symmetrically arranged and fixedly connected to the upper side of the installation base plate, providing a stable and balanced support frame for the conveyor platform. During the transportation of the W-pin copper wire, the side plates can effectively resist the lateral force caused by factors such as the copper wire's own weight, movement inertia, and possible external force interference, preventing the conveyor platform from deformation, shaking, etc., and ensuring the integrity of the conveyor platform's own structure and the stability of its working state.

[0018] Furthermore, a gland plate for pressing the W-pin is movably connected to the conveying platform, and a supporting assembly for lifting the gland plate is provided on one side of the conveying platform, and the supporting assembly includes a supporting cylinder, a cylinder fixing part and a cylinder speed regulating valve;

[0019] The side wall of the belt support plate is provided with a support column and a hinge pin for cooperating with the supporting cylinder.

[0020] By adopting the above technical solution, the cover plate movably connected on the conveyor table can play a role in pressing the W-pin copper wire. When the rotating seat drives the conveyor table to turn, the cover plate can press the copper wire on the belt to avoid the position deviation of the copper wire, thereby ensuring that the copper wire can be accurately conveyed to the subsequent process according to the predetermined path. The cover plate is lifted by the top support assembly, and the lifting and pressing actions of the cover plate can be flexibly controlled with the help of the top support cylinder, cylinder fixings and cylinder speed control valve. For example, when the W-pin copper wire is being conveyed, the top support cylinder can drive the cover plate to lift up, so that the copper wire can be smoothly put into place; and when the conveyor table needs to turn, the top support cylinder retracts to press the cover plate down to achieve the pressing function. At the same time, the cylinder speed control valve can also be used to accurately adjust the movement speed of the top support cylinder to adapt to the steering rhythm of the rotating seat and the actual working conditions.

[0021] Furthermore, the sliding guide rail seat includes a U-shaped seat body arranged above the annular seat body, a screw drive assembly arranged on the U-shaped seat body and used to cooperate with the mounting base plate, and a belt drive assembly fixedly connected to the side wall of the frame body and used to provide driving force for the screw drive assembly;

[0022] The U-shaped seat body is provided with a slide rail and a slide block on the upper side, and the mounting base plate is fixedly connected to the upper side of the slide block.

[0023] By adopting the above technical solution, the screw drive assembly cooperates with the mounting base plate, and with the help of the driving force provided by the belt drive assembly, the precise position adjustment of the mounting base plate is achieved. A slide rail and a sliding block are provided on the upper side of the U-shaped seat body, and the mounting base plate is fixedly connected to the upper side of the sliding block, so that the conveyor can slide smoothly along the slide rail during movement. The cooperation between the slide rail and the sliding block provides a good guiding effect, reducing the possibility of instability such as left-right deviation and shaking of the conveyor during movement.

[0024] Furthermore, the bending fixing seat includes a strip base, a base fixing cover fixedly connected to the upper side of the strip base, a deformation guide seat fixedly connected between the strip base and the base fixing cover, and a T-shaped connecting plate fixedly connected to the frame body, the base fixing cover is fixedly connected to the lower side of the T-shaped connecting plate, the strip base is provided with a first linear channel for the W-pin to pass through on the upper side, and the deformation guide seat is provided with a second linear channel connected to the first linear channel on the upper side.

[0025] By adopting the above technical solution, the bending fixing seat is fixedly connected to the frame body through the T-shaped connecting plate, and the base fixing cover is fixedly connected to the lower side of the T-shaped connecting plate. The multi-layer connection structure enables the bending fixing seat to be firmly installed on the frame. When the W-pin copper wire is bent, it can withstand various forces generated during the copper wire bending process. The first linear channel opened on the upper side of the strip base is for the W-pin copper wire to pass through, so that the copper wire has a clear and fixed placement position before entering the bending link, limiting the lateral movement of the copper wire in the plane, and ensuring that it is always in an accurate position while waiting for bending and in the initial stage of bending. The second linear channel opened on the upper side of the deformation guide seat is connected to the first linear channel. During the bending process of the W-pin copper wire, when the copper wire begins to bend and deform, the second linear channel of the deformation guide seat reasonably guides the deformation of the copper wire, so that the stress distribution of the copper wire during the bending process is more uniform, which helps to avoid irregular twisting, bending angle deviation and other problems of the copper wire during bending, and makes the shape of the copper wire after bending more accurate and standardized.

[0026] Furthermore, the deformation guide seat is symmetrically provided with arc guide surfaces for matching with the W-pin on both sides of the second linear channel, and the arc guide surfaces are located at the end position of the deformation guide seat away from the frame body.

[0027] By adopting the above technical solution, when the W-pin copper wire is bent, the arc guide surface can provide a smooth transition area for the bending of the copper wire. When the copper wire begins to change from a straight state to a curved state, it can naturally change its direction along the arc guide surface, making the bending process smoother and more continuous, avoiding problems such as sudden angle changes and irregular bends caused by sudden bending, thereby improving the bending accuracy of the copper wire and ensuring that the shape of the bent copper wire can accurately meet the design requirements of windings in equipment such as motors or transformers.

[0028] Furthermore, the strip base has an upper step surface for installing the deformation guide seat on a side away from the frame body, and the deformation guide seat has a lower step surface matching the upper step surface on the lower side.

[0029] By adopting the above technical solution, the upper step surface of the strip base matches the lower step surface of the deformation guide seat, and the deformation guide seat can fit tightly when installed on the strip base, so that the upper surfaces of the strip base and the deformation guide seat are in the same horizontal plane, so that the first linear channel and the second linear channel can be smoothly connected, ensuring the stability of the bending accuracy.

[0030] Furthermore, the feeding mechanism is arranged on a side of the frame body away from the synchronous conveying mechanism, and the feeding mechanism includes two groups of belt drive assemblies arranged at intervals in an upper and lower manner, and a transmission gap is left between the two belt drive assemblies for the W-pin to pass through, and the transmission gap is opposite to the first linear channel.

[0031] By adopting the above technical solution, the feeding mechanism conveys the W-pin copper wire through two groups of belt drive components arranged at intervals in the upper and lower parts. The belt drive itself has the advantages of smooth transmission, low noise, and buffering and vibration absorption. The W-pin copper wire is placed in the transmission gap between the two groups of belt drive components. The friction between the belt and the copper wire can make the copper wire move forward smoothly, avoiding unstable conditions such as jumping and jamming of the copper wire during transportation, and ensuring that the copper wire can enter the bending fixed seat in a stable state. The transmission gap is directly opposite to the first linear channel, so that the W-pin copper wire can enter the first linear channel on the bending fixed seat accurately after being conveyed by the feeding mechanism. It avoids the problems such as the need for manual secondary adjustment or the possible bending error due to inaccurate entry position of the copper wire, and improves the degree of automation and production efficiency of the production process.

[0032] Furthermore, the shearing mechanism is arranged on the side wall of the frame body and is located adjacent to the lifting screw slide. The shearing mechanism includes pneumatic scissors for shearing W-pins and a lifting adjustment slide and a horizontal adjustment slide for adjusting the position of the pneumatic scissors.

[0033] By adopting the above technical solution, the lifting adjustment slide and the horizontal adjustment slide of the shearing mechanism can accurately adjust the position of the pneumatic scissors in multiple dimensions, quickly position the pneumatic scissors to the precise shearing point, and ensure that the shearing meets the process requirements.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] The lifting screw slide adjusts the height of the bending motor seat and the cam bearing follower ensures the accuracy of the bending angle and arc. The W-pin copper wire is reasonably guided by the guiding structures such as the second linear channel and arc guide surface of each channel in the bending fixed seat and the deformation guide seat, so that the bent copper wire can perfectly fit the motor stator slot structure and optimize the electromagnetic induction effect of the winding. At the same time, the stress distribution of the copper wire is more uniform during the bending process, avoiding problems such as irregular distortion and bending angle deviation, and improving the bending quality in all aspects.

[0036] The feeding mechanism, bending mechanism, synchronous conveying mechanism and shearing mechanism cooperate with each other to realize the automatic continuous operation from W-pin copper wire conveying, precise bending, receiving and synchronously rotating the copper wire after conveying and bending to shearing on demand. The various mechanisms are closely connected. For example, the rotating seat of the synchronous conveying mechanism and the bending flange rotate synchronously to ensure smooth receiving. The structure of the conveying table and related adjustment components ensure stable conveying and flexible position adjustment. The feeding mechanism can accurately convey the copper wire to the bending fixed seat, etc., which greatly improves the production efficiency and ensures the continuity and efficiency of the entire process.

[0037] The sliding guide seat of the synchronous conveying mechanism can accurately adjust the position of the conveying table, and the shearing mechanism can adjust the position of the pneumatic scissors in multiple dimensions. Each key part has a flexible adjustment function, so that it can adapt to different specifications of W-pin copper wires, different bending and production process requirements, and enhance the versatility of the device. The multi-layer connection structure of the bending fixed seat, the stable frame of the conveying table and other mechanism structures are reasonably and firmly designed to ensure the smooth operation of the W-pin copper wire during the processing process, reduce shaking, offset, etc., and the operation of the components is relatively simple and intuitive, which is convenient for manual operation and equipment maintenance, and improves the overall stability and convenience of operation.

[0051] The strip base 24 is provided with an upper step surface 241 on the top surface on the side away from the frame body 6, and the deformation guide seat 23 is provided with a lower step surface 231 on the lower side. The deformation guide seat 23 is engaged with the strip base 24 through the lower step surface 231, so that the top surface of the deformation guide seat 23 and the top surface of the strip base 24 can be in the same horizontal plane.

[0052] A first linear channel 242 is provided at the middle position of the top side of the strip base 24 along the length direction, and a second linear channel 232 is provided at the middle position of the top side of the deformation guide seat 23 along the length direction.

The deformation guide seat 23 is symmetrically provided with arc guide surfaces 233 on both sides of the second linear channel 232 to guide the bending of the W-pin. The arc guide surface 233 is located at the end position of the deformation guide seat 23 away from the frame body 6.

[0053] Reference Figure 4 and Figure 5 The bending mechanism 3 includes a bending flange 31, a cam bearing follower 32, a bending motor 33, a planetary reducer 34, a bending motor 33 seat and a lifting screw slide 36. The lifting screw slide 36 is fixedly connected to the side wall of the frame body 6, and the bending motor 33 seat is slidably installed along the height direction of the lifting screw slide 36. The bending motor 33 and the planetary reducer 34 are both installed on the upper side of the bending motor 33 seat. The bending flange 31 is installed on the lower side of the bending motor 33 seat and is electrically connected to the planetary reducer 34. The cam bearing follower 32 is installed on the lower side of the bending flange 31. Figure 1The bent flange 31 is directly above the base fixing cover 22 .

[0054] The shearing mechanism 5 is arranged on the side wall of the frame body 6 and is located adjacent to the lifting screw slide 36. The shearing mechanism 5 includes a pneumatic scissors 51 for shearing the W-pin and a lifting adjustment slide 52 and a horizontal adjustment slide 53 for adjusting the position of the pneumatic scissors 51.

[0055] Reference Figure 1 and Figure 6 The synchronous conveying mechanism 4 includes a rotating seat 41, a conveying platform 42 and a sliding guide rail seat 43. The rotating seat 41 is arranged on the frame body 6 and is used to rotate synchronously with the bending flange 31. The conveying platform 42 is arranged on the rotating seat 41 and is used to receive the bent W-pin. The sliding guide rail seat 43 is used to adjust the position of the conveying platform 42.

[0056] The rotating seat 41 includes an annular seat body 411 fixedly connected to the side wall of the frame body 6, a rotating shaft 412 disposed in the annular seat body 411 and located at the central axis, a drag chain 413 matched with the rotating shaft 412, a seat body driving motor 414 disposed below the rotating shaft 412 and capable of rotating synchronously with the bending motor 33, and a synchronous reducer 415 matched with the seat body driving motor 414. A ring plate 4111 for shielding the drag chain 413 is fixedly connected to the upper side of the annular seat body 411.

[0057] Reference Figure 1 and Figure 7 The conveying platform 42 is arranged above the ring plate 4111, and the conveying platform 42 includes a mounting base plate 421, two side plates 422 symmetrically arranged and fixedly connected to the upper side of the mounting base plate 421, and a synchronous wheel 423, a synchronous belt 424 and a belt support plate 425 installed between the two side plates 422. The lower side of the mounting base plate 421 is used to connect with the sliding guide rail seat 43. In this embodiment, the power source of the synchronous wheel 423 is preferably a servo motor with a relatively stable driving force, and the output end of the servo motor is equipped with a planetary reducer 34.

[0058] A pressure cover plate 426 for pressing the W-pin is hinged on one side of the conveyor 42, and a supporting assembly 427 for lifting the pressure cover plate 426 is installed on the side plate 422, so that the W-pin can be pressed on the synchronous belt 424. The supporting assembly 427 includes a supporting cylinder 4271, a cylinder fixing part 4272 and a cylinder speed regulating valve 4273. The side wall of the belt support plate 425 is provided with a support 428 and a hinge pin 429 for cooperating with the supporting cylinder 4271.

[0059] Combination Figure 8The sliding guide rail seat 43 is arranged between the ring plate 4111 and the conveying platform 42 and is used to adjust the position of the conveying platform 42. The bottom side of the mounting base plate 421 of the conveying platform 42 is mounted on the sliding guide rail seat 43. The sliding guide rail seat 43 includes a U-shaped seat body 431 arranged above the annular seat body 411, a screw drive assembly 432 arranged on the U-shaped seat body 431 and used to cooperate with the mounting base plate 421, and a belt drive assembly 433 fixedly connected to the side wall of the frame body 6 and used to provide driving force for the screw drive assembly 432. The U-shaped seat body 431 is provided with a slide rail 4311 and a sliding block 4312 on the upper side, and the mounting base plate 421 is fixedly connected to the upper side of the sliding block 4312. The screw drive assembly 432 has a drive block 4321 for being fixedly connected to the lower side of the mounting base plate 421, and the drive block 4321 is driven by a screw.

[0060] The lower side of the U-shaped seat body 431 is fixedly connected to the rotating shaft 412 of the rotating seat 41. The rotating seat 41 rotates with the bending mechanism 3, and at the same time drives the conveying platform 42 to rotate from the X direction to the Y direction, and then rotates to the -X direction, so that the bent W-pin on the conveying platform 42 obtains flexible assistance.

[0061] The implementation principle of a flexible W-pin bending auxiliary device in the embodiment of the present application is as follows: the device is arranged around the frame body 6, the feeding mechanism 1 is located at the rear side, and cooperates with the bending fixing seat 2 at the front side to transport the W-pin copper wire. The bending mechanism 3, the bending fixing seat 2, and the synchronous conveying mechanism 4 are installed in sequence from top to bottom on the front side of the frame body 6, and the shearing mechanism 5 is on the front side of the frame body 6 and adjacent to the bending mechanism 3.

[0062] Two groups of belt drive assemblies 11 are arranged at intervals in the upper and lower parts, and use servo motors as driving devices, and use the friction between the belts to act on the W-pin copper wire placed in the transmission gap 111, driving it to move forward smoothly. And because the transmission gap 111 is in line with the first linear channel 242 of the bending fixed seat 2, the copper wire can be accurately transported to the bending fixed seat 2.

[0063] The first linear channel 242 on the strip base 24 defines the initial position of the copper wire, and the second linear channel 232 of the deformation guide seat 23 is connected thereto and circular arc guide surfaces 233 are arranged on both sides. When the copper wire is bent, the circular arc guide surfaces 233 play a guiding role, allowing the copper wire to smoothly transition along the circular arc guide surfaces when it changes from a straight line to a bent state, so that the bending process is smooth and the stress distribution is uniform.

[0064] The bending motor 33 seat slides through the lifting screw slide 36 to adjust the height. The bending motor 33 and the planetary reducer 34 are installed on the upper side of the motor seat, and drive the bending flange 31 to rotate through electrical connection. The cam bearing follower 32 located on the lower side of the bending flange 31 accurately controls the bending action.

[0065] The annular seat body 411 of the rotating seat 41 is fixed on the side wall of the frame body 6, and its internal rotating shaft 412 is driven by the seat body driving motor 414 and the synchronous reducer 415 to realize synchronous rotation with the bending motor 33. The rotating seat 41 rotates with the bending mechanism 3, driving the conveying platform 42 to rotate accordingly, ensuring that the bent W-pin copper wire can be timely received and smoothly change the conveying direction, realizing flexible conveying in different directions such as rotating from the X direction to the Y direction and -X direction, and ensuring the continuity of the entire conveying process.

[0066] The mounting base plate 421 is connected to the annular seat body 411 through the sliding guide rail seat 43, and the position adjustment is achieved by the screw drive assembly 432 on the U-shaped seat body 431. The two side plates 422 provide a stable support structure for the conveyor 42. The synchronous wheel 423 drives the synchronous belt 424 and the belt support plate 425 under the drive of the servo motor and the planetary reducer 34 to realize the copper wire conveying. The pressure cover plate 426 is controlled to be lifted or pressed down by the top support assembly 427, and is flexibly operated at different stages (such as when the copper wire is in place or the conveyor 42 is turned), pressing the copper wire against the synchronous belt 424 to avoid its position deviation and ensure the stability of the copper wire during the conveying process.

[0067] The shearing mechanism 5 is located on the side wall of the frame body 6 and is adjacent to the lifting screw slide 36.
