Description

Technical Field

[0001] The invention relates to the technical field of motor coils, and in particular to a glue rolling machine and a glue rolling method for gluing motor coils. Background Art

[0002] The gluing process of motor coils is an important step in the motor manufacturing process. A specific adhesive is applied to the surface of the coil to form a uniform insulating layer, which can not only improve the insulation performance and mechanical strength of the coil, but also improve the seismic and vibration resistance of the coil, and reduce damage and failures caused by external forces.

[0003] At present, the existing glue rolling machines, such as Chinese patent CN220358996U, disclose a glue rolling machine for hollow cup motor coils. The device can adsorb multiple groups of coils through magnetic blocks, so when in contact with the glue coating component, it can complete the purpose of processing multiple groups of coils at the same time, thereby improving work efficiency. The collection component can collect excess glue, on the one hand to prevent the glue from flowing freely and polluting the operating environment, on the other hand, the excess glue can be collected and reused.

[0004] Another example is Chinese patent CN214314950U, which discloses a glue rolling machine for hollow cup motor coils. The glue rolling machine performs glue application and glue rolling on the hollow cup motor coils through an automatic assembly line system, which not only reduces manpower and improves work efficiency, but also achieves convenient and safe operation.

[0005] However, when the two types of glue rolling machines are performing glue rolling processing on the coil, they adopt the method of directly brushing glue on the coil or performing glue rolling operation through assembly line glue rolling method. This may cause uneven coating of glue on the coil when brushing or rolling glue, which may not only affect the insulation performance of the coil after glue rolling processing, but also may affect the subsequent assembly process of the coil, and thus affect the normal use of the entire motor.

[0027] 2. The present invention utilizes the mechanical pressure of the motor coil on the outside of the soft layer to squeeze the optical fiber at a local position, thereby causing a slight bend in it.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 10 The present invention provides a technical solution: a glue rolling machine for gluing motor coils, comprising a mounting frame 1, the top of the mounting frame 1 is set as a top plate 2, and a partition plate 3 is provided in the middle, and also includes:

[0041] Two spiral drums 4 are mounted on the top of the partition 3 and can rotate relative to each other. The outer walls of the two spiral drums 4 are covered with spiral fins. The rotation directions of the two spiral fins are opposite, and the pitch of the spiral fins is greater than the length of the motor coil 9;

[0042] The rubber rolling assembly is installed at the bottom of the top plate 2, and the rubber rolling assembly includes a rubber rolling roller 6 that can roll glue on the motor coil 9. The gap between the rubber rolling roller 6 and the two spiral rollers 4 constitutes a rubber rolling conveying channel for the motor coil 9, and the length of the spiral roller 4 is greater than the length of the rubber rolling roller 6.

[0043] When the rubber rolling machine is in use, the motor coil 9 to be rolled is placed between the gaps between the spiral fins of the two spiral rollers 4. Figure 1 and Figure 2 The motor coil 9 can be put in from the gap in front of the rubber rolling roller 6, which can be placed manually or by conveying with a conveyor belt. The put-in motor coil 9 is supported by the arc surface outer walls of the two spiral rollers 4, so that the motor coil 9 is pushed forward and conveyed by the spiral fins as the spiral rollers 4 rotate. When the motor coil 9 moves to the bottom of the rubber rolling roller 6 and enters the rubber rolling conveying channel, since the rotation direction of the rubber rolling roller 6 is the same as the rotation direction of one of the spiral rollers 4, the motor coil 9 is driven to rotate while being conveyed, and at the same time, the rubber rolling roller 6 performs rubber rolling processing on the surface of the motor coil 9;

[0044] The outer walls of the two spiral rollers 4 are both provided with an anti-stick coating, which can avoid or reduce the adhesion of the glue during the glue rolling process, and can also make the glue rolling degree of the motor coil 9 more uniform.

[0045] It is worth mentioning that, during the process of rolling the glue, since the rotation direction of one of the spiral drum 4 and the glue rolling roller 6 is opposite to the rotation direction of the motor coil 9, the glue liquid rolled on the motor coil 9 can be evenly immersed in the gap of the motor coil 9, and the rotation direction of the other spiral drum 4 is the same as the rotation direction of the motor coil 9. By utilizing the mutual force of friction between the two, the glue liquid on the motor coil 9 can accelerate the immersion rate and make the rolling of the glue more uniform.

[0046] After the rubber rolling is completed, as the motor coil 9 is transported, when it is separated from the rubber rolling roller 6, the motor coil 9 will stop rotating after losing the external rotational power of the rubber rolling roller 6, and continue to transport as the two spiral rollers 4 rotate until the next process.

[0047] In this way, through the design of the glue rolling conveying channel, not only can the motor coil 9 be conveyed quickly and automatically, but the glue rolling coating on the motor coil 9 can also be more uniform, so that a uniform insulating layer can be formed after curing, which can not only ensure the insulation performance and mechanical strength of the coil, but also ensure the seismic performance and vibration resistance of the coil, reducing damage and failures caused by external forces.

[0048] In one of the more preferred embodiments, an implementation method for accelerating the curing of the motor coil 9 after the glue rolling is provided;

[0049] A circular side plate 10 is provided at a position of the mounting frame 1 near the end of the spiral drum 4, and a driven ring 11 is rotatably installed on the outer wall of the circular side plate 10. An active ring 12 that can rotate intermittently is also installed on the outer wall of the circular side plate 10 through a rotating shaft. The active ring 12 and the driven ring 11 are eccentrically arranged in the vertical direction, and a transmission rod 27 is rotatably installed between corresponding positions of the driven ring 11 and the active ring 12, and the connection between the transmission rod 27 and the active ring 12 is rotatably connected through a connecting shaft 13 fixed on the outer wall of the transmission rod 27, one end of the connecting shaft 13 passes through the active ring 12 and is coaxially installed with a purple light tube 26, and when the connecting shaft 13 and the purple light tube 26 are located at the conveying channel position, the connecting shaft 13 and the motor coil 9 are concentrically arranged.

[0050] For details, please refer to Figure 2 , Figure 5 and Figure 6Among the adhesives used on the motor coil 9, some types of adhesives can be cured by ultraviolet rays, such as UV curing adhesives, etc. Therefore, when the spiral roller 4 transports the rolled motor coil 9 to the position of the ultraviolet lamp 26, the ultraviolet lamp 26 will irradiate the motor coil 9 from the inside, thereby curing the inner ring of the motor coil 9, accelerating the formation of the inner ring, and also providing preparation for subsequent testing;

[0051] Then, as the motor coil 9 is pushed out, it will be sleeved on the connecting shaft 13. At this time, the active ring 12 is driven to rotate by an external driving source, such as a motor, etc. Figure 6 , under the transmission action of the transmission rod 27, the driven ring 11 will be driven to rotate together, so that the connecting shaft 13 will rotate intermittently to turn the motor coil 9 away, and transfer the empty connecting shaft 13 and the ultraviolet light tube 26 to the previous position;

[0052] In this way, the motor coil 9 can be automatically unloaded by rotating the connecting shaft 13, and because the motor coil 9 moves around the periphery of the ultraviolet lamp tube 26, the ultraviolet lamp tube 26 is located at the center of the motor coil 9, which can ensure that the glue can be irradiated and cured more evenly, thereby providing a guarantee for the quality of the subsequent insulating layer.

[0053] Moreover, it is worth mentioning that since the active ring 12 and the driven ring 11 are eccentrically arranged in the vertical direction, they will always remain in a vertical state during the rotation of the transmission rod 27, that is, the connecting shaft 13 will make circular motion with the active ring 12, but it itself will not rotate in the axial direction, providing preparation for subsequent detection.

[0054] In one of the more preferred embodiments, an implementation method capable of detecting the inner ring of the motor coil 9 is provided;

[0055] The outer wall of the connecting shaft 13 is also covered and fixed with a rotor core 14, and the diameter of the rotor core 14 is the same as the diameter of the permanent magnet rotor. The outer wall of the rotor core 14 is also wrapped with a soft layer 15. The outer wall of the soft layer 15 is provided with multiple groups of detection parts distributed in an annular shape. The detection part includes an optical fiber 16 embedded in the outer wall of the soft layer 15. Both ends of the optical fiber 16 are bent and extended into the rotor core 14, and are respectively connected to a light transmitter 17 and a light receiver 18 installed in the rotor core 14.

[0056] The outer wall of the active ring 12 is also fixed with a fixed disk 19 which is sleeved on the outer wall of the connecting shaft 13, and the connecting shaft 13 is rotatably connected with the penetration point of the fixed disk 19. The outer wall of the fixed disk 19 is provided with a clamping part for fixing the wire at the edge of the motor coil 9.

[0057] In the hollow cup motor, after the motor coil 9 is rolled and solidified to form an insulating layer, the motor coil 9 will be put on the permanent magnet rotor and then installed in the motor housing. In the design of the motor, a certain air gap is usually deliberately left between the permanent magnet rotor and the coil. The existence of the air gap can reduce the magnetic pull of the permanent magnet on the coil, thereby reducing the hysteresis loss and noise of the motor. Similarly, the air gap can also provide a certain design flexibility, allowing the magnetic flux between the rotor and the coil to be adjusted without direct contact, so as to optimize the performance of the motor.

[0058] Therefore, it is necessary to detect the diameter of the inner ring of the motor coil 9 and the inner diameter of the insulating layer formed after the glue is cured, and to perform assembly-type detection on them to ensure the existence of the air gap during the subsequent installation process. The specific detection method is as follows:

[0059] For details, please refer to Figure 5 and Figure 8 As can be seen from the previous content, after the motor coil 9 is cured by the ultraviolet lamp 26, it will continue to be pushed outward by the spiral drum 4, so that the motor coil 9 is sleeved on the soft layer 15 outside the rotor core 14. Since the diameter of the rotor core 14 is the same as the diameter of the permanent magnet rotor, a substitution method can be achieved to improve the detection result. The thickness of the soft layer 15 corresponds to the width of the air gap. When the motor coil 9 is sleeved on the soft layer 15, the inner ring of the motor coil 9 will apply pressure to the optical fiber 16 embedded in the outer wall of the soft layer 15. The signal change of the optical fiber 16 can be used to determine the pressure change range of the motor coil 9 when it is sleeved into the soft layer 15. If the pressure increases at a certain point, it means that the inner diameter of the motor coil 9 may be due to uneven glue coating or too large a coil gap at that point, resulting in excessive glue infiltration into the inner ring, forming a bulge on the inner ring, thereby achieving the purpose of detecting the inner diameter of the motor coil 9. Then, as the motor coil 9 is sleeved, the silk thread at its front end (see Fig.10 ) will be fixed by the clamping part on the fixed disk 19, so as to achieve the purpose of rotation limitation.

[0060] Since the distribution of the optical fiber 16 is relatively dispersed, only the position in contact with the optical fiber 16 can be detected when the motor coil 9 is inserted. It can be seen from the above content that when the active ring 12 rotates, the connecting shaft 13 will make a circular axis motion with the active ring 12, but it itself will not rotate along the axial direction. Therefore, the connecting shaft 13 will rotate relative to the fixed disk 19, that is, the rotor core 14 and the soft layer 15 will rotate relative to the motor coil 9 along with the active ring 12, so that the optical fiber 16 on the outer wall of the soft layer 15 can scan and contact the inner ring of the motor coil 9, and then the inner ring of the motor coil 9 can be fully detected to improve the comprehensiveness of the detection result.

[0061] It is worth mentioning that the detection method of optical fiber 16 is as follows:

[0062] The mechanical pressure exerted by the motor coil 9 on the outside causes the optical fiber 16 to be squeezed at a local position, thereby causing a slight bend in it. This bending causes the transmission path of light in the optical fiber 16 to change, thereby causing loss. By measuring the change in microbend loss, the pressure on the optical fiber 16 can be monitored, thereby achieving the purpose of detecting the inner circle of the motor coil 9. What's more, it can be captured and analyzed by the monitoring system to obtain the bulge of the inner circle of the motor coil 9.

[0063] In one of the more preferred embodiments, an implementation of a clamping portion is provided;

[0064] The clamping portion includes a plurality of arc grooves 20 distributed in a ring shape on the outer wall of the fixed disk 19, and a compression airbag 21 is installed in each arc groove 20. An air pump 24 is also installed on the outer wall of the fixed disk 19. The air pump 24 is connected to each compression airbag 21 through an air guide tube 25 covered on the outer ring of the fixed disk 19.

[0065] For details, please refer to Fig. 9 When the motor coils 9 are all covered on the soft layer 15, the silk threads thereon will extend into the arc groove 20, and then the air pump 24 will inflate air into each compression airbag 21 through the air guide tube 25, thereby expanding the compression airbag 21, clamping and fixing the silk threads on the motor coils 9, and thus limiting and fixing the motor coils 9, so as to facilitate the subsequent relative rotation with the soft layer 15 to detect it.

[0066] In one of the more preferred embodiments, an implementation method for removing the motor coil 9 from the soft layer 15 is provided;

[0067] The fixed plate 19 between two adjacent arc-shaped grooves 20 is set as a middle strip 22, and each middle strip 22 is provided with a jet port 23 inside. The air outlet of the jet port 23 is flush with the edge of the motor coil 9, and each jet port 23 is also connected to the air pump 24.

[0068] As can be seen from the above content, after the airbag 21 is pressed to fix the motor coil 9, the air outlet of the air jet 23 is flush with the edge of the motor coil 9. When the motor coil 9 needs to be removed, the air pump 24 can be used to exhaust air to the air jet 23, and the motor coil 9 can be blown off by the instantaneous action of the high-pressure airflow to complete the removal process;

[0069] It can also be taken down manually or by using a robotic arm, depending on the specific situation.

[0070] In one of the more preferred embodiments, an implementation of a rubber rolling assembly is provided;

[0071] The rubber rolling assembly also includes a rubber outlet pipe 7 installed below the top plate 2, and the rubber outlet of the rubber outlet pipe 7 corresponds to the outer wall of the rubber rolling roller 6. A scraper 8 for evenly spreading the glue on the rubber rolling roller 6 is also installed at the bottom of the top plate 2. A glue box 5 for replenishing the glue into the rubber outlet pipe 7 is also installed on the top of the top plate 2, and the glue box 5 and the rubber outlet pipe 7 are connected by a rubber delivery pipe.

[0072] For details, please refer to Figure 2 When rolling glue, the glue box 5 replenishes the glue liquid in the glue outlet pipe 7 through the glue delivery pipe. At the same time, when the glue squeezed out of the glue outlet pipe 7 is squeezed onto the glue rolling roller 6, as the glue rolling roller 6 rotates, the scraper 8 will evenly spread the glue on the glue rolling roller 6, thereby providing preparation for subsequent glue rolling.

[0073] In one of the more preferred embodiments, a feeding part is provided on both sides of the mounting frame 1, and the two feeding parts correspond to the two resting positions of the motor coil 9 respectively. The feeding part includes two unloading channels 28 with an inclined design, and when the motor coil 9 detaches from the soft layer 15, it will fall onto the two unloading channels 28.

[0074] See also Figure 1 and Figure 2 As can be seen from the above content, the motor coil 9 can be separated from the soft layer 15 by using the jet nozzle 23 to eject air. By designing two sets of feeding parts, the motor coils 9 that have passed the test and those that have failed the test can be transported. The motor coils 9 can be separated at different positions.

[0075] Among them, it is preferred that along the rotation direction of the active ring 12, the ones in front of it are unqualified and the ones behind it are qualified. In this way, a purple light structure can be added between the two to further solidify the qualified motor coils 9.

[0076] In one of the more preferred embodiments, one end of the two spiral drums 4 passes through the side wall of the mounting frame 1 for rotation, and gears are fixed to the protruding parts, and the two gears are meshed, and one of the spiral drums 4 is driven to rotate by an external motor.

[0077] See also Figure 1 By utilizing the mutual meshing of the two gears, the two spiral rollers 4 can rotate synchronously and at the same time, the rotation directions of the two can be opposite.

[0078] In one of the more preferred embodiments, the rotor mold core 14 and one end of the soft layer 15 close to the ultraviolet light tube 26 are both configured as a conical surface, and a transition arc surface is provided at the connection between the rotor mold core 14 and the soft layer 15 .

[0079] A method for rolling glue using a glue rolling machine for gluing motor coils, comprising the following steps:

[0080] S1, put the motor coil 9 to be rolled into the gap between the spiral fins of the two spiral rollers 4, and support the motor coil 9 through the curved outer walls of the two spiral rollers 4, so that the motor coil 9 is pushed forward and transported through the spiral fins as the spiral rollers 4 rotate;

[0081] S2, when the motor coil 9 moves to the bottom of the rubber rolling roller 6 and enters the rubber rolling conveying channel, the rotation direction of the rubber rolling roller 6 is the same as the rotation direction of one of the spiral rollers 4, so the motor coil 9 is driven to rotate while conveying, and the rubber rolling roller 6 performs rubber rolling processing on the surface of the motor coil 9;

[0082] S3. During the glue rolling process, the rotation direction of one of the spiral drum 4 and the glue rolling roller 6 is opposite to that of the motor coil 9, so that the glue liquid rolled on the motor coil 9 can be evenly immersed in the gap of the motor coil 9, and the rotation direction of the other spiral drum 4 is the same as that of the motor coil 9. The mutual force of friction between the two is used to accelerate the immersion rate of the glue liquid on the motor coil 9 and make the glue rolling more uniform.

[0083] S4, as the motor coil 9 is transported, when it is separated from the rubber rolling roller 6, the motor coil 9 stops rotating after losing the external rotational power of the rubber rolling roller 6, and continues to be transported as the two spiral rollers 4 rotate until the next process;

[0084] S5. The motor coil 9 subsequently transported continuously repeats the above steps S2-S4.

[0085] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
