Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of winding machines, in particular to a motor rotor carbon fiber winding machine. BACKGROUND

[0002] Winding carbon fiber coated with glue on the motor rotor is a rotor reinforcement technology for high-performance motors, the core purpose of which is to solve the mechanical failure risk of the rotor during high-speed rotation and improve the overall performance of the motor.

[0003] When winding carbon fiber on the motor rotor, a winding machine needs to be used. When the winding machine is working, the carbon fiber tows are unwound, coated with glue by the glue coating device, and then directly wound on the surface of the rotor.

[0004] The existing glue coating device usually first delivers glue to the surface of the glue coating roller, and then scrapes off the excess glue to accurately control the thickness of the glue layer on the roller surface. When the carbon fiber tows pass through the surface of the glue coating roller, the glue on the roller surface is uniformly transferred to the surface of the base material under the action of pressure and adhesion to complete the glue coating.

[0005] In the above glue coating method, when multiple tows are coated in parallel, the tension difference between the tows will cause uneven glue coating. The contact between some tows with small tension is loose, which is easy to cause too much glue coating, resulting in an increase in the moment of inertia of the rotor. The contact between some tows with large tension is tight, which is easy to cause insufficient glue coating, resulting in exposed fibers and decreased interlayer bonding force, ultimately affecting the quality of the motor rotor produced by the winding machine.

DETAILED DESCRIPTION

[0020] The specific embodiments of the present application are further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0021] The "top surface", "bottom", "bottom surface" are used as a reference to the normal use state of the motor rotor carbon fiber winding machine, only for the convenience of describing the present application and simplifying the description, and are not indicative or suggestive of the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0022] As shown in Figures 1-7 A motor rotor carbon fiber winding machine, comprising a machine body 1, a glue applying mechanism 5, a winding mechanism 4, a plurality of guide rollers 3 and a plurality of drive rollers 2 are arranged on the machine body 1, the guide rollers 3 and the drive rollers 2 are used to guide the tows 6 to advance along a first path; the tows 6 pass through the glue applying mechanism 5 along the first path, and then the tows 6 are wound onto the motor rotor by the winding mechanism 4; the glue applying mechanism 5 comprises a glue storage box 53 internally provided with a glue applying roller 56, the top of the glue storage box 53 is open, and a box cover 52 is hingedly connected at the opening; the tows 6 comprise first unit tows 61 attached to the top surface of the glue applying roller 56 with a preset wrapping angle and second unit tows 62 attached to the bottom surface of the glue applying roller 56 with a preset wrapping angle, the number of the first unit tows 61 is equal to the number of the second unit tows 62, and the first unit tows 61 and the second unit tows 62 are arranged axially staggered along the glue applying roller 56.

[0023] The above-mentioned winding machine is suitable for applying glue to the carbon fiber tows 6 and then winding them onto the motor rotor to achieve the reinforcing effect of the motor rotor. The glue applied is usually a thermosetting resin. The guide rollers 3 and the drive rollers 2 jointly guide the tows 6 to advance along the first path. The drive rollers 2 are respectively connected with separate drive motors, and the drive motors provide power to the drive rollers 2, so that each drive roller 2 can independently control its rotation speed. While providing forward driving force to the tows 6, the tension of the tows 6 can be controlled by the speed difference of the drive rollers 2. The tows 6 are composed of a plurality of parallel carbon fiber filaments. The first unit tows 61 and the second unit tows 62 each comprise one or more filaments. The tows are divided into a plurality of unit tows, and each unit tow passes above and below the glue applying roller 56 in a staggered manner. Each unit tow is separated and kept at a certain interval from each other, thereby reducing the mutual obstruction between the filaments in the tows 6 during the glue applying process. The filaments in the unit tows can be uniformly and fully contacted with the glue. Then, the unit tows after being applied with glue are combined into the entire tows 6. In this way, the uniformity of the glue applying process can be improved. The tows are orderly wound onto the motor rotor, and the quality of the motor rotor produced by the winding machine can be improved.

[0024] Further improvement is as follows Figure 6 , 10As shown in Figs. 14 and 15, the glue roller 56 has an elliptical cross section, and a guide groove 566 is formed on each side surface at both ends of the short axis of the elliptical cross section, extends perpendicularly to the axial direction of the glue roller 56, and is arranged alternately along the axial direction of the glue roller 56. On the same side surface of the glue roller 56, the minimum distance between two adjacent guide grooves 566 is greater than or equal to the width of the guide groove 566, and the length of the guide groove 566 is less than the length of the long axis of the elliptical cross section. The box cover 52 is fixedly connected with a mounting frame 59, the glue roller 56 is rotatably connected to the mounting frame 59, and a guide roller 3 is also rotatably connected to the mounting frame 59. The glue roller 56 has a hollow inner cavity, and the bottom of each guide groove 566 is provided with a glue outlet hole 567 connected to the inner cavity. The bottom of the glue storage box 53 is provided with a power pump 533 connected to the inner cavity through a hose 532.

[0025] In the above-described winding machine, the box cover 52 and the glue storage box 53 are connected to each other through the hydraulic support rod 54, the glue roller 56 is mounted on the box cover 52 through the mounting frame 59, and the glue roller 56 can be lifted to the outside of the glue storage box 53 when the box cover 52 is opened, so as to facilitate the operator to arrange the fiber bundle on the glue roller 56. The number of carbon fiber filaments contained in the first unit bundle 61 and the second unit bundle 62 is determined so as to ensure that the sum of the diameters of the filaments is less than or equal to the width of the guide groove 566, so that the filaments can be laid flat in the guide groove 566, reducing the stacking of the filaments, and thus the glue can uniformly and fully contact with each filament. The elliptical glue roller 56 can increase the contact range between the unit bundle and the surface of the glue roller 56, improve the glue coating time of the unit bundle, and make the unit bundle fully and uniformly coated with glue. The guide rollers 3 are arranged on the front and rear sides of the glue roller 56 along the first path, so that the fiber bundle 6 can stably pass through the glue roller 56 and be combined under the action of the rear guide roller 3. The working principle is as follows. The glue stored in the glue storage box 53 is sent into the inner cavity of the glue roller 56 through the hose 532 by the power pump 533, and then is discharged from each glue outlet hole 567 into the inner cavity of each guide groove 566. A plurality of glue outlet holes 567 can be arranged in each guide groove 566 and extend in the radial direction of the glue roller 56, so that the glue can fully fill the inner cavity of the guide groove 566, and the filaments can be fully coated with glue when passing through the inner cavity of the guide groove 566. The length of the guide groove 566 is less than the length of the long axis of the elliptical cross section, so that the side surfaces of the glue roller 56 at both ends of the long axis are smooth.

[0026] The process of separating the fiber bundle 6 into multiple unit bundles and distributing them on both sides of the glue roller 56 is manually performed by an operator. The guide groove 566 is arranged so that the surface of the glue roller 56 has a comb structure, which can comb the fiber bundle 6 to untangle the internal entanglement of the fiber bundle 6. In this way, the internal filaments of the fiber bundle 6 can also be in full contact with the glue. At the same time, the guide groove 566 is also used to guide the forward direction of the entire fiber bundle 6, limit the displacement of the filaments along the axial direction of the glue roller 56, and prevent the filaments from being too dispersed during the gluing process, which makes it difficult to combine into a complete fiber bundle 6. Furthermore, the guide groove 566 has a certain depth and can accommodate more glue inside, so that the filaments can be in full contact with the glue. The guide grooves 566 are arranged on both surfaces of the glue roller 56, and the spacing and width between the guide grooves 566 are limited, so that each guide groove 566 can completely cover the width of the fiber bundle 6 along the axial direction of the glue roller 56, and prevent the unit bundles from being too dispersed.

[0027] Further improvements are as shown in FIGS. Figure 12 、 14 and 15, one end of the glue roller 56 is coaxially fixedly connected with a rotating shaft 561, the rotating shaft 561 is rotatably connected with the mounting frame 59, the box cover 52 is provided with a third power member 57 in transmission connection with the rotating shaft 561, the other end of the glue roller 56 is provided with an open end, and an end cover 562 is arranged on the open end; the end cover 562 is fixedly connected with a filter cover 563, the filter cover 563 is located inside the inner cavity, the end cover 562 is provided with a glue inlet 568 communicating with the inside of the filter cover 563 and a plug-in port 565 communicating with the inner cavity, the hose 532 is in communication with the glue inlet 568, and the plug-in port 565 is sealingly and plug-inly provided with a second heater 564.

[0028] In the aforementioned winding machine, the end cap 526 is fixedly connected to the coating roller 56 by screws. During operation, the hose 532 first delivers the glue to the inside of the filter screen 563 through the glue inlet 568. After the glue is filtered by the filter screen 563, it is discharged from the glue outlet 567. Due to the viscosity of the glue, the glue discharged from the glue outlet 567 can also exert a certain thrust on the monofilaments, thereby maintaining a certain tension on the monofilaments. Furthermore, the fluidity of the glue allows the thrust generated to act on each monofilament individually, improving the consistency of the thrust on each monofilament and ensuring that each monofilament has a consistent tension. The second heater 564 is a heating rod that can heat the glue when the temperature is too low, maintaining good fluidity of the glue. Moreover, the process of the glue passing through the inside of the coating roller 56 is also a process of stirring and mixing the glue. This prevents the performance degradation of the adhesive due to sedimentation and stratification. The rotating shaft 561 is connected to the mounting bracket 59 via bearings. The third power component 57 includes a motor fixedly connected to the cover 52. Both the drive shaft of the motor and the rotating shaft 561 are equipped with pulleys, and a belt is provided between the two pulleys. The motor drives the coating roller 56 to rotate back and forth. The sides of the coating roller 56 at both ends of the long shaft are smooth. When the monofilaments inside the carbon fiber bundle 6 are too severely wrapped, the coating roller 56 is rotated so that the unit bundle comes into contact with the smooth surface of the coating roller 56. In this way, the unit bundle is no longer restricted by the guide groove 566 and can be dispersed along the axial direction of the coating roller 56 under its own tension. Then, the coating roller 56 is rotated in the opposite direction to reset it, so that the unit bundle re-enters the interior of each guide groove 566 in an orderly manner, which is conducive to untangling the cross-wrap between monofilaments.

[0029] Further improvements include, for example Figures 4-8 As shown, a feed inlet 531 is provided on the top of one side of the glue storage box 53. A cleaning roller 58 is provided on the side of the glue storage box 53 and the box cover 52 near the feed inlet 531. The cleaning roller 58 located on the box cover 52 is raised and lowered on the box cover 52. When the box cover 52 is closed, the two cleaning rollers 58 are parallel to each other and abut against each other radially.

[0030] The outer circumferential surface of the cleaning roller 58 is provided with an adhesive tape layer, the cleaning roller 58 located on the glue storage box 53 is connected through the connecting seat 581, the end of the cleaning roller 58 is connected with the connecting seat 581 through a bearing, the box cover 52 is provided with a vertical extending guide groove 582, the connecting seat 581 is slidably arranged in the guide groove 582, and the cleaning roller 58 located on the box cover 52 is connected with the connecting seat 581 located in the guide groove 582 through a bearing; when the box cover 52 is covered, the volatilization of the glue in the glue storage box 53 can be reduced, and the environmental protection performance is improved, and the cleaning roller 58 on the box cover 52 can be closely attached to the lower cleaning roller 58 under the action of gravity; the filament 6 passes between the two cleaning rollers 58, and the dust and impurities on the filament 6 can be stuck through the adhesive tape layer on the cleaning roller 58, so that the pollution to the glue is reduced, and the quality of the motor rotor produced by the winding machine is improved.

[0031] Further improvement is that, as shown in Figure 3 The winding mechanism 4 comprises a fixed seat 401 fixedly connected with the machine body 1, a first direction along the width direction of the machine body 1, a translation seat 402 slidably arranged on the fixed seat 401 along the first direction, and a first power member 403 arranged on the fixed seat 401 and drivingly connected with the translation seat 402.

[0032] Specifically, the translation seat 402 is provided with a second power member 405, and the second power member 405 is a motor, the driving shaft of which is fixedly connected with the chuck 404. The first power member 403 comprises a motor and a lead screw, and the lead screw is threadedly connected with the translation seat. When the motor rotor is installed, one end is clamped and fixed by the chuck 404, and the other end is abutted and fixed by the abutting seat 406. The first power member 405 drives the motor rotor to rotate, so that the coated filament 6 is wound on the outer circumference of the motor rotor. At the same time, the translation seat 402 is driven by the lead screw to reciprocate along the width direction of the machine body 1, so that the motor rotor reciprocates along the axial direction of itself, and the filament 6 is orderly wound on the motor rotor.

[0033] Further improvement is that, as shown in Figure 12 and 13As shown, the glue roller 56 is provided with two mutually parallel extrusion rollers 55 immediately behind the first path, one of which is rotationally arranged on the mounting frame 59, and the other is connected to the mounting frame 59 by elastic members at both ends. The specific structure of the elastic member includes a guide rod 552 extending radially along the extrusion roller 55, which is fixedly connected to the mounting frame 59, and a guide sleeve 551 is sleeved on the guide rod 552, one end of the extrusion roller 55 is rotationally connected with the guide sleeve 551, and a nut 553 is threadedly connected to the end of the guide rod 552 away from the mounting frame 59. A spring 554 is sleeved on the guide rod 552 and connected to the nut 553 and the guide sleeve 551 at both ends.

[0034] Specifically, the filament 6 coated by the glue roller 56 passes between the two extrusion rollers 55, and the extrusion rollers 55 apply pressure to the filament 6 to squeeze out excess glue inside and make the glue flow back to the inside of the glue storage tank 53, thereby effectively controlling the amount of glue on the filament 6. The nut 553 can be used to adjust the compression amount of the spring 554, thereby adjusting the thrust generated by the spring 554 on the guide sleeve 551, and further effectively adjusting the extrusion force between the two extrusion rollers 55, thereby effectively controlling the glue content inside the filament 6.

[0035] Further improvement is as shown in Figure 6 、 7 , 9, 11 and 12, the inside of the tank cover 52 is provided with a partition 523, which divides the inside space of the tank cover 52 into mutually independent first and second areas, the first area is in communication with the glue storage tank 53, and the second area is provided with a first heater 513 and a plurality of guide rollers 3, a transfer port 522 is formed in the partition 523, and a discharge port 521 is formed in the inner wall of the second area; the top of the second area is open, and a top cover 51 is provided on the opening, the first heater 513 is arranged on the inner side of the top cover 51, and the outer side of the top cover 51 is provided with a circulation pipe 511 communicating with the second area at both ends, and a gas pump 512 is arranged on the circulation pipe 511. The advancing path of the part of the filament 6 in the second area is S-shaped.

[0036] After the filament 6 is coated with glue, it needs to pass through a path during winding onto the motor rotor. During this process, the glue on the filament 6 is prone to dripping, and when the filament 6 contacts the guide roller 3 and the drive roller 2, the glue is also prone to transferring to the guide roller 3 and the drive roller 2, thereby contaminating the guide roller 3 and the drive roller 2 and affecting the glue content of the filament 6, resulting in a lack of glue on the filament 6 and affecting the quality of the motor rotor produced by the winding machine.

[0037] To address the aforementioned issues, the filament bundle after passing through the extrusion roller 55 is fed into a second region. A first heater 513 is installed inside the second region to heat the filament bundle 6, thereby pre-curing the adhesive on the filament bundle 6 to reduce the fluidity of the adhesive and minimize the dripping and transfer of adhesive during subsequent filament bundle transmission. Specifically, under the guidance of the guide roller 3, the filament bundle 6 is cleaned by the cleaning roller 58 and enters the first area through the feed port 531. Then, it comes into contact with the glue coating roller 58 for glue application. After the excess glue is removed by the extrusion roller 55, it enters the second area through the transfer port 522. In the second area, the glue is pre-cured by heating and then output from the discharge port 521. Finally, it is sent to the winding mechanism 4 for winding. The forward path of the part of the filament bundle 6 in the second area is S-shaped, which can extend the heating time and heating uniformity of the filament bundle 6. The setting of the circulation pipe 511 and the Qibang 512 can promote the air inside the second area to pass through the filament bundle 6, further improving the heating uniformity of the filament bundle and improving the pre-curing effect of the filament bundle 6. The openable top cover 51 facilitates the maintenance of the filament bundle 6 inside the second area, improving the convenience of winding machine maintenance.
