Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a magnetic pole winding winding device. Background Art

[0002] The stator of the motor includes magnetic poles, which are used to generate the magnetic field required for the rotor to rotate. The magnetic poles are composed of an iron core and an excitation winding placed on the iron core. Among them, the excitation winding is usually divided into two types: aluminum foil winding and copper wire winding; the aluminum foil winding is formed by laminating aluminum foil, which has the advantages of low cost and light weight; while the copper wire winding is made of copper wire, which has the characteristics of high mechanical strength and good conductivity.

[0003] The surface of the aluminum foil winding is paved with an insulating film, which can play a certain insulating role. The magnetic pole is the core subcomponent of the Changdao high-speed maglev to achieve the suspension and guidance function, and there are five different shapes. When winding the aluminum foil winding, different shapes require different winding lengths within the same angle of rotation of the main shaft. However, limited by the existing technical level, the existing magnetic pole winding winding equipment cannot be wound continuously, nor can it flexibly adjust the tension of the aluminum foil and the insulating paper during the winding process. The tension mismatch will cause the aluminum foil winding to be broken due to excessive tension, and the aluminum foil winding will also be blocked due to insufficient tension. The failure rate during the winding process is high, and the winding quality and winding efficiency cannot be guaranteed. Summary of the invention

[0074] 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.

[0075] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0076] The embodiment of the present invention discloses a magnetic pole winding winding device, as shown in the attached Figure 1 As shown, it includes an aluminum foil unwinding device 11, an insulating film unwinding device 12, a winding winding device 13, an aluminum foil tensioning adjustment device 14 and an insulating film tensioning adjustment device 15.

[0077] Aluminum foil 01 is wound on the aluminum foil unwinding device 11, which is used to unwind the aluminum foil 01. The aluminum foil unwinding device 11 includes an aluminum foil 01 winding roller, an aluminum foil 01 roller fixing rod, and an aluminum foil 01 roller driving motor. The aluminum foil 01 winding roller is used for winding the aluminum foil 01. A central through hole is formed in the center of the aluminum foil 01 winding roller. The aluminum foil 01 roller fixing rod is provided with a plurality of radially telescopic limit sliding shoes. When all the limit sliding shoes are radially expanded, the limit sliding shoes abut against the inner side wall of the central through hole, so that the aluminum foil 01 winding roller is fixedly connected to the aluminum foil 01 roller fixing rod; when all the limit sliding shoes are radially contracted, the limit sliding shoes are separated from the central through hole, so that the aluminum foil 01 winding roller is conveniently replaced. The aluminum foil 01 roller driving motor and the aluminum foil 01 roller fixing rod are used to drive the aluminum foil 01 roller fixing rod to drive the aluminum foil 01 winding roller to rotate to release the aluminum foil 01. The insulating film 02 is wound on the insulating film unwinding device 12. The structure of the insulating film unwinding device 12 is the same as that of the aluminum foil unwinding device 11, and the details can be referred to the above content, which will not be described in detail here.

[0078] The aluminum foil tensioning adjustment device 14 is arranged between the aluminum foil unwinding device 11 and the winding winding device 13, and is used to adjust the tension of the aluminum foil 01, so that the aluminum foil 01 always maintains the set tension, that is, the aluminum foil 01 is kept tensioned between the aluminum foil unwinding device 11 and the winding winding device 13 with the set tension, so as to avoid the aluminum foil 01 being pulled apart due to excessive tension, and also to avoid the aluminum foil 01 being loose and blocked due to too little tension. The insulating film tensioning adjustment device 15 is arranged between the insulating film unwinding device 12 and the winding winding device 13, and is used to adjust the tension of the insulating film 02, so that the insulating film 02 always maintains the specified tension, that is, the insulating film 02 is kept tensioned between the insulating film unwinding device 12 and the winding winding device 13 with the specified tension, so as to avoid the insulating film 02 being too large or too small. The set tension in the text refers to the optimal tension of the aluminum foil 01 in the tensioned state, which can be flexibly adjusted according to the thickness and composition of the aluminum foil 01. The specified tensioning force in the text refers to the optimal tensioning force of the insulating film 02 in a tensioned state, which can be flexibly adjusted according to the thickness and composition.

[0079] During winding, the aluminum foil unwinding device 11 and the insulating film unwinding device 12 rotate at the same time to release the aluminum foil 01 and the insulating film 02 respectively, the aluminum foil tensioning adjustment device 14 adjusts the tensioning force of the aluminum foil 01, and the insulating film tensioning adjustment device 15 adjusts the tensioning force of the insulating film 02, so that the tensioning forces of the aluminum foil 01 and the insulating film 02 are always matched during the entire winding process, ensuring that the aluminum foil 01 and the insulating film 02 are fully unfolded after tensioning, and under the guidance of the winding winding device 13, the unfolded insulating film 02 intersects with the aluminum foil 01 along the tangent direction of the winding winding device 13, so that the insulating film 02 is attached to the surface of the aluminum foil 01 to form a layered winding, and the layered winding is wound on the winding winding device 13, the entire winding process can be carried out continuously, the manual participation is reduced, and the aluminum foil 01 and the insulating film 02 maintain appropriate tension, the failure rate is also reduced, and the winding quality and winding efficiency are improved.

[0080] The aluminum foil tensioning and adjusting device 14 includes an aluminum foil tensioning wheel group 141, an aluminum foil preload adjusting component 142, and an aluminum foil tensioning force adjusting component 143. The aluminum foil tensioning wheel group 141 is used for the aluminum foil 01 to pass through in sequence. The aluminum foil tensioning wheel group 141 includes at least one aluminum foil tensioning wheel to ensure that the aluminum foil 01 is fully tensioned. As a preferred embodiment, the aluminum foil tensioning wheel group 141 includes a central aluminum foil tensioning wheel, a left aluminum foil tensioning wheel, and a right aluminum foil tensioning wheel. The left aluminum foil tensioning wheel and the right aluminum foil tensioning wheel are symmetrically arranged on the central aluminum foil tensioning wheel, and the center lines of the central aluminum foil tensioning wheel, the left aluminum foil tensioning wheel, and the right aluminum foil tensioning wheel are distributed in a triangular shape. The diameter of the central aluminum foil tensioning wheel is larger than the diameter of the left aluminum foil tensioning wheel and the diameter of the right aluminum foil tensioning wheel, respectively. The aluminum foil 01 passes through the right aluminum foil tensioning wheel, the central aluminum foil tensioning wheel, and the left aluminum foil tensioning wheel from right to left in sequence.

[0081] The aluminum foil preload force adjustment component 142 is arranged between the aluminum foil tensioning wheel group 141 and the aluminum foil unwinding device 11, and is used to adjust the preload force of the aluminum foil 01. The aluminum foil tension force adjustment component 143 is arranged between the aluminum foil tensioning wheel group 141 and the winding winding device 13, and is used to adjust the tension force of the aluminum foil 01. The combination of the aluminum foil preload force adjustment component 142 and the aluminum foil tension force adjustment component 143 divides the tension force adjustment of the aluminum foil 01 into two stages: preload force adjustment and tension force adjustment, with a larger adjustment range and compensation range, and better adaptability.

[0082] As a preferred embodiment, the aluminum foil tensioning wheel set 141, the aluminum foil pre-tightening force adjustment component 142 and the aluminum foil tensioning force adjustment component 143 are distributed in a triangular shape, so that the aluminum foil 01 is fully tensioned. The aluminum foil pre-tightening force adjustment component 142 and the aluminum foil tensioning force adjustment component 143 are arranged at the same height, and the aluminum foil tensioning wheel set 141 is respectively higher than the aluminum foil pre-tightening force adjustment component 142 and the aluminum foil tensioning force adjustment component 143, so that the aluminum foil 01 is bent into a V-shaped structure, thereby ensuring that the aluminum foil 01 is fully tensioned.

[0083] The aluminum foil preload force adjustment assembly 142 includes an aluminum foil preload force adjustment wheel 1421, an aluminum foil preload force adjustment cylinder 1422, an aluminum foil preload force detection member and a position detection member 1423. The aluminum foil preload force adjustment wheel 1421 is used for the aluminum foil 01 to bypass. The aluminum foil preload force adjustment cylinder 1422 is fixedly connected to the aluminum foil preload force adjustment wheel 1421. The aluminum foil preload force adjustment cylinder 1422 is arranged vertically, that is, the aluminum foil preload force adjustment cylinder 1422 is retracted in the vertical direction, so that the aluminum foil preload force adjustment cylinder 1422 drives the aluminum foil preload force adjustment wheel 1421 to move up and down, so as to drive the aluminum foil preload force adjustment wheel 1421 to lift the aluminum foil 01, so as to adjust the preload force of the aluminum foil 01. The aluminum foil preload force detection member is used to detect the current preload force applied by the aluminum foil 01 to the aluminum foil preload force adjustment wheel 1421, and can be a pressure sensor. The position detection member 1423 is used to detect whether the aluminum foil preload force adjustment wheel 1421 moves down to the target position, and can be a position sensor. The target position in the text refers to the limit position of the aluminum foil preload force adjustment wheel 1421 moving down.

[0084] When the aluminum foil preload force detection component detects that the current preload force is less than the set preload force, the aluminum foil preload force detection component sends a signal to the controller. After receiving the signal, the controller makes a judgment and sends a command to the aluminum foil preload force adjustment cylinder 1422 to control the aluminum foil preload force adjustment cylinder 1422 to automatically retract. The aluminum foil preload force adjustment cylinder 1422 drives the aluminum foil preload force adjustment wheel 1421 to move downward, thereby increasing the tensioning force of the aluminum foil 01. The controller has a high degree of automation and a high adjustment accuracy, which is beneficial to improving the winding quality.

[0085] When the position detection component 1423 detects that the aluminum foil preload adjustment wheel 1421 moves down to the target position, the position detection component 1423 sends a signal to the controller. After receiving the signal, the controller performs judgment and processing, and sends an instruction to the winding winding device 13 to control the winding winding device 13 to stop, specifically controlling the winding winding motor of the winding winding device 13 to automatically stop, so as to prevent the aluminum foil preload adjustment wheel 1421 from moving down excessively and tearing the aluminum foil 01.

[0086] The aluminum foil tension adjustment assembly 143 includes an aluminum foil tension adjustment wheel 1431, an aluminum foil tension adjustment cylinder 1432, and a tension detection member. The aluminum foil tension adjustment wheel 1431 is used for the aluminum foil 01 to pass around. The aluminum foil tension adjustment cylinder 1432 is fixedly connected to the aluminum foil tension adjustment wheel 1431. The aluminum foil tension adjustment cylinder 1432 is also arranged vertically, that is, the aluminum foil tension adjustment cylinder 1432 is retracted in the vertical direction, so that the aluminum foil tension adjustment cylinder 1432 drives the aluminum foil tension adjustment wheel 1431 to move up and down, so as to drive the aluminum foil tension adjustment wheel 1431 to lift the aluminum foil 01, so as to adjust the pre-tension of the aluminum foil 01. The tension detection member is used to detect the current tension applied by the aluminum foil 01 to the aluminum foil tension adjustment wheel 1431, and can be a pressure sensor.

[0087] When the tension detection component detects that the current tension is inconsistent with the set tension, the tension detection component sends a signal to the controller. After receiving the signal, the controller makes a judgment and sends a command to the aluminum foil tension adjustment cylinder 1432, automatically starting the aluminum foil tension adjustment cylinder 1432, so that the aluminum foil tension adjustment cylinder 1432 drives the aluminum foil tension adjustment wheel 1431 to pull the aluminum foil 01, thereby automatically adjusting the tension of the aluminum foil 01, with high adjustment accuracy, which can effectively improve the winding quality.

[0088] Taking into account that the pole winding is not a regular circle but a rectangle, the lengths of the aluminum foil 01 and the insulating film 02 required per unit time are not the same. The pole winding winding equipment also includes a material compensation device, which is used to compensate the feed for the winding winding device 13 within a set time period to avoid affecting the winding quality due to length mismatch between the aluminum foil 01 or the insulating film 02.

[0089] The material compensation device includes a winding angle detection member, which is used to detect the current rotation angle of the winding winding device 13, which can be an encoder. When the winding angle detection member detects that the current rotation angle reaches the set rotation angle, the winding angle detection member sends a signal to the controller. After the controller performs judgment processing, it sends an instruction to the aluminum foil preload adjustment cylinder 1422 and the aluminum foil tension adjustment cylinder 1432, and controls the aluminum foil preload adjustment cylinder 1422 and the aluminum foil tension adjustment cylinder 1432 to extend upward synchronously within the set time period, so that the aluminum foil preload adjustment wheel 1421 and the aluminum foil tension adjustment wheel 1431 both release the aluminum foil 01 by automatically lifting, and the released aluminum foil 01 can just compensate for the shortage caused by the change in the shape of the magnetic pole winding, avoiding the aluminum foil 01 from being torn due to insufficient length, and can achieve accurate compensation of materials, and the winding quality is higher.

[0090] The pole winding winding equipment also includes an aluminum foil shaping device 16 for shaping the aluminum foil 01, removing burrs on the surface of the aluminum foil 01 to prevent the burrs from scratching the insulating layer, which is beneficial to improving the winding quality. The aluminum foil shaping device 16 includes a shaping support, a shaping pressure plate, a shaping locking rod and a reset spring. The shaping support is fixedly arranged and mainly plays a supporting role. The shaping support is fixed with a shaping shaft, and the shaping pressure plate can be rotatably arranged on the shaping shaft so that the shaping pressure plate rotates around the shaping shaft. The shaping locking rod is arranged on the shaping pressure plate to lock the shaping pressure plate when the shaping pressure plate presses the aluminum foil 01. The reset spring is arranged between the shaping pressure plate and the shaping support, and is used to assist the shaping pressure plate in resetting to move away from the aluminum foil 01 after the shaping locking rod is unlocked.

[0091] When the shaping pressure plate rotates counterclockwise around the shaping axis for a certain angle, the shaping pressure plate presses the aluminum foil 01 toward one of the aluminum foil tensioning wheels and pushes down the shaping locking rod at the same time. The shaping locking rod is inserted into the limit locking hole provided in the shaping support, and the shaping pressure plate remains stably pressed on the aluminum foil 01; when the aluminum foil 01 moves along the aluminum foil tensioning wheel assembly 141, the aluminum foil tensioning wheel and the shaping pressure plate squeeze the two sides of the aluminum foil 01 respectively to shape the aluminum foil 01 to ensure that the two sides of the aluminum foil 01 are flush; when the shaping locking rod is lifted, the shaping pressure plate is unlocked, and the reset spring restores its elastic deformation, driving the shaping pressure plate to rotate clockwise around the shaping axis for a certain angle until the shaping pressure plate is reset.

[0092] The magnetic pole winding winding device further includes at least one set of aluminum foil centering devices 17 disposed between the winding winding device 13 and the aluminum foil tensioning adjustment device 14, which is used to adjust the position of the aluminum foil 01 relative to the insulating film 02 so that the aluminum foil 01 and the insulating film 02 are kept aligned. As a preferred embodiment, the magnetic pole winding winding device is specifically provided with two sets of aluminum foil centering devices 17, which are arranged horizontally, and the aluminum foil 01 is wound horizontally between the two sets of aluminum foil centering devices 17.

[0093] The aluminum foil centering device 17 includes an aluminum foil centering adjustment wheel, an aluminum foil centering adjustment slide, an aluminum foil centering adjustment lead screw, an aluminum foil centering adjustment motor, and an aluminum foil centering detection member 171. The aluminum foil centering adjustment wheel is used for winding the aluminum foil 01, the aluminum foil centering adjustment slide is fixedly connected to the aluminum foil centering adjustment wheel, the aluminum foil centering adjustment lead screw cooperates with the aluminum foil centering adjustment slide, and the aluminum foil centering adjustment motor is fixedly connected to the aluminum foil centering adjustment lead screw. The aluminum foil centering detection member 171 is used to detect whether the aluminum foil 01 is in a set centering position, and can be a position sensor or a distance sensor.

[0094] When the aluminum foil centering detection part 171 detects that the aluminum foil 01 is not in the set centering position, the aluminum foil centering detection part 171 sends a signal to the controller. After the controller makes a judgment, it sends a command to the aluminum foil centering adjustment motor, automatically starts the aluminum foil centering adjustment motor, and drives the aluminum foil centering adjustment screw to rotate forward or reverse. The aluminum foil centering adjustment screw drives the aluminum foil centering adjustment slide to move linearly, so that the aluminum foil centering adjustment slide drives the aluminum foil centering adjustment wheel to slide back and forth along the width direction of the aluminum foil 01 until the aluminum foil 01 and the insulating film 02 are aligned. High-precision adjustment is achieved in a closed-loop control mode, which is conducive to improving the winding quality. It should be noted that the centering here means that the projection of the aluminum foil 01 completely overlaps with the insulating film 02 in the vertical direction.

[0095] The insulating film tension adjustment device 15 is a self-balancing structure, including an insulating film tension adjustment wheel 151, an insulating film tension adjustment rod 152 and a limit stop rod 154. The insulating film tension adjustment wheel 151 is used for the insulating film 02 to bypass. The insulating film tension adjustment wheel 151 is located obliquely below the insulating film unwinding device 12, so that the insulating film 02 is kept tilted and tensioned between the insulating film tension adjustment wheel 151 and the insulating film unwinding device 12. The insulating film tension adjustment rod 152 can be rotatably arranged, that is, the insulating film tension adjustment rod 152 adopts the lever principle. One end of the insulating film tension adjustment rod 152 is suspended by a lifting spring 153, and the other end thereof is rotatably provided with an insulating film tension adjustment wheel 151, and the tension of the insulating film 02 is adjusted by the gravity of the insulating film tension adjustment wheel 151 and the elastic force of the lifting spring 153. The limit stop rod 154 is fixedly arranged. When the insulating film tension adjusting wheel 151 moves down to the lowest position, the insulating film tension adjusting rod 152 abuts against the limit stop rod 154 to limit the extreme position of the insulating film tension adjusting rod 152 to prevent the insulating film tension adjusting wheel 151 from moving down excessively and tearing the insulating film 02.

[0096] The magnetic pole winding winding device further includes at least one set of insulating film centering devices 18 disposed between the winding winding device 13 and the insulating film tensioning adjustment device 15, which are used to adjust the position of the insulating film 02 relative to the aluminum foil 01 so that the insulating film 02 is centered with the aluminum foil 01. As a preferred embodiment, the magnetic pole winding winding device is specifically provided with two sets of insulating film centering devices 18, which are arranged horizontally, but the insulating film 02 is wound between the two sets of insulating film centering devices 18 in an inclined direction.

[0097] The insulating film centering device 18 also includes an insulating film centering adjustment wheel, an insulating film centering adjustment slide, an insulating film centering adjustment lead screw, an insulating film centering adjustment motor and an insulating film centering detection member 181. The insulating film centering adjustment wheel is used for winding the insulating film 02. The insulating film centering adjustment slide is fixedly connected to the insulating film centering adjustment wheel. The insulating film centering adjustment lead screw cooperates with the insulating film centering adjustment slide. The insulating film centering adjustment motor is fixedly connected to the insulating film centering adjustment lead screw. The insulating film centering detection member 181 is used to detect whether the insulating film 02 is in a specified centering position, and can be a position sensor or a distance sensor.

[0098] When the insulating film centering detection part 181 detects that the insulating film 02 is not in the specified centering position, the insulating film centering detection part 181 sends a signal to the controller. After the controller performs judgment and processing, it sends an instruction to the insulating film centering adjustment motor, automatically starting the insulating film centering adjustment motor, so that the insulating film centering adjustment motor drives the insulating film centering adjustment screw to rotate forward or reverse, and the insulating film centering adjustment screw drives the insulating film centering adjustment slide to move linearly, so that the insulating film centering adjustment slide drives the insulating film centering adjustment wheel to slide back and forth along the width direction of the insulating film 02 until the insulating film 02 is centered with the aluminum foil 01. High-precision adjustment can also be achieved to improve the winding quality.

[0099] The magnetic pole winding winding equipment also includes an aluminum foil clamping device 19 and an aluminum foil shearing detection part. The aluminum foil clamping device 19 is used to clamp the aluminum foil 01. The aluminum foil shearing detection part is used to detect whether the aluminum foil 01 is sheared, and can be a pressure detection part or an obstacle detection part. The aluminum foil clamping device 19 includes a left aluminum foil abutment roller and a right aluminum foil abutment roller that are arranged opposite to each other, and an aluminum foil clamping cylinder connected to the left aluminum foil abutment roller and the right aluminum foil abutment roller respectively. The aluminum foil clamping cylinder is a double-piston cylinder, which makes the left aluminum foil abutment roller and the right aluminum foil abutment roller approach each other or separate from each other.

[0100] After winding is completed, the aluminum foil 01 needs to be cut; when the aluminum foil cutting detection component detects that the aluminum foil 01 is cut, the aluminum foil cutting detection component sends a signal to the controller. After the controller makes a judgment, it sends a command to the aluminum foil clamping cylinder. The aluminum foil clamping cylinder drives the left aluminum foil abutment roller and the right aluminum foil abutment roller to retract each other to clamp the aluminum foil 01, so as to avoid excessive impact on the aluminum foil 01 when the tension of the aluminum foil 01 is released, thereby preventing the aluminum foil 01 from being torn off, which is beneficial to improving reliability.

[0101] The magnetic pole winding winding equipment also includes an insulating film clamping device 20 and an insulating film shearing detection part. The insulating film clamping device 20 is used to clamp the insulating film 02. The insulating film shearing detection part is used to detect whether the insulating film 02 is sheared, and can be a pressure detection part or an obstacle detection part. The insulating film clamping device 20 includes an insulating film fixed clamping block, an insulating film movable clamping block, and an insulating film clamping cylinder connected to the insulating film movable clamping block, so that the insulating film clamping cylinder drives the insulating film movable clamping block to move relative to the insulating film fixed clamping block to clamp or release the insulating film 02.

[0102] After the winding is completed, the insulating film 02 needs to be cut; when the insulating film shear detection part detects that the insulating film 02 is cut, the insulating film shear detection part sends a signal to the controller. After the controller makes a judgment and processing, it sends an instruction to the insulating film clamping cylinder. The insulating film clamping cylinder drives the insulating film movable clamp to automatically lean against the insulating film fixed clamp, so that the insulating film fixed clamp and the insulating film movable clamp cooperate to clamp the insulating film 02, avoiding excessive impact on the insulating film 02 when the tension of the insulating film 02 is released, which may cause the insulating film 02 to be torn off, and can also improve reliability.

[0103] In addition, each device of the magnetic pole winding winding equipment in the present invention is arranged vertically, with a more compact structure and smaller occupied space.

[0104] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
