Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly, and particularly relates to a magnetic sheet mounting device for rotor assembly. Background Technique

[0002] The brushless motor, as an important branch of modern motor technology, is widely used in fields such as household appliances, power tools, automobiles, aerospace, etc. It mainly replaces the traditional carbon brush and commutator with an electronic commutator to achieve contactless rotation of the motor, thereby reducing mechanical wear, extending the service life of the motor, and improving the overall performance.

[0003] The core component of a brushless motor is the rotor, and the rotor magnetic sheet is a key component of the rotor. In the current market, most rotor magnetic sheets adopt traditional adhesive fixing technology. This process not only involves manual coating of adhesives but also subsequent manual installation and positioning. Each step highly depends on the operator's skills and experience. Therefore, the limitations of manual operation have led to a series of problems: First, the installation speed is slow, seriously hindering the improvement of the efficiency of large-scale production; second, it is difficult to precisely control the amount of glue applied manually, resulting in significant differences in the glue layer thickness and uniformity between products of different batches, thereby affecting the consistency of the finished products and the final performance. In addition, the correct installation of the rotor magnetic sheet requires that the magnetic pole directions of adjacent magnetic sheets are strictly opposite to form a closed rotating magnetic field. However, in actual operation, this delicate operation requirement is often difficult to achieve due to human negligence, and the incorrect arrangement of magnetic sheets directly leads to the failure of the motor function, greatly increasing the defective rate. Content of the Utility Model

[0004] The utility model aims to provide a magnetic sheet mounting device for rotor assembly to improve the assembly efficiency and quality of magnetic sheets in the rotor.

[0005] To achieve the above object, the utility model adopts the following technical scheme: A magnetic sheet mounting device for rotor assembly includes a support frame, a rotor housing conveying mechanism and a magnetic sheet mounting mechanism provided on the support frame. The rotor housing conveying mechanism includes a conveying tooling and a conveying sprocket. The magnetic sheet mounting mechanism includes a magnetic sheet integration mechanism and an S-pole feeding mechanism and an N-pole feeding mechanism distributed on both sides of the magnetic sheet integration mechanism. The magnetic sheet integration mechanism is used to pre-arrange the magnetic sheets uniformly; the magnetic sheet integration mechanism includes a vertical sliding component and a rotating component. The bottom of the rotating component is detachably connected with a rotating head. A plurality of pairs of fixing grooves for accommodating magnetic sheets are evenly arranged on the outer periphery of the rotating head. The rotating head is made of a magnetic metal material; the number of fixing grooves between the S-pole feeding mechanism and the N-pole feeding mechanism is odd. The S-pole feeding mechanism and the N-pole feeding mechanism both include a magnetic sheet placement bin and a feeding cylinder; a glue coating component for coating the outside of the magnetic sheet is also installed on the support frame.

[0006] The principle and advantages of this solution are:

[0007] 1. In actual application, the rotor housing conveying mechanism, the magnetic sheet mounting mechanism, and the glue coating assembly in this solution realize the automatic operation of the whole process from the arrangement, feeding, glue coating to the installation of magnetic sheets. The combined use of the conveying tooling and the conveying sprocket ensures the stable transmission of the rotor housing on the production line, greatly improving the continuity and speed of the assembly of the rotor housing and the magnetic sheets, and fundamentally solving the problem of low production efficiency caused by traditional manual installation. Moreover, the automated process not only reduces labor costs but also helps to achieve large-scale production, conforming to the trend of modern manufacturing industry to respond to market demands efficiently and quickly.

[0008] 2. This solution sets up an S-pole feeding mechanism and an N-pole feeding mechanism to separately provide S-pole magnetic sheets and N-pole magnetic sheets, and the number of fixed slots between the two feeding mechanisms is odd, effectively ensuring that during the rotation of the rotating head, the magnetic sheets are installed into the rotor housing in an alternating arrangement of S-pole and N-pole. Fundamentally eliminating the magnetic sheet arrangement errors caused by human negligence, not only greatly reducing the defective product rate but also ensuring the formation of the closed rotating magnetic field of the motor and ensuring the normal functioning of the motor.

[0009] 3. In this solution, all the magnetic sheets in a rotor housing are pre-uniformly arranged by the magnetic sheet integration mechanism, and then the vertical sliding component is used to drive the rotating head and the magnetic sheets downward into the rotor housing, ensuring that the position, direction, and installation force of each magnetic sheet are consistent. At the same time, the glue coating assembly uniformly coats the outer side of the magnetic sheets received on the rotating head, avoiding the uneven glue layer thickness caused by manual operation, improving the consistency and performance stability of the finished product, significantly reducing the performance differences between different batches of products, and enhancing the overall product quality.

[0010] Furthermore, a stop component for stopping the conveying tooling is evenly arranged on the support frame. The stop component includes an inductor, a stop cylinder, and a stop seat arranged at the end of the output shaft of the stop cylinder.

[0011] Through the cooperation of the inductor, the stop cylinder, and the stop seat, it is ensured that each conveying tooling stops moving when it reaches below the feeding mechanism for the assembly process. And compared with the frequent start-stop of the whole conveying sprocket, which consumes time and energy and exacerbates the start-stop wear of components, intercepting the conveying tooling by the stop component can effectively ensure production continuity and be more economical.

[0012] Furthermore, clamping components are symmetrically arranged on both sides of the support frame. The clamping components include clamping cylinders and clamping blocks connected to the ends of the output shafts of the clamping cylinders.

[0013] The position of the rotor housing on the conveying tooling is further adjusted and determined by the clamping components to ensure the precise alignment between the rotor housing and the rotating head, realize the precise assembly of the magnetic sheets, and guarantee the production quality.

[0014] Furthermore, a jacking assembly is provided below the rotating head corresponding to the support frame, and the jacking assembly is used to jack up the conveying tooling and the rotor housing upward.

[0015] The rotor housing is jacked up upward between the clamping assemblies on both sides by the jacking assembly, so that the conveying tooling is separated from the conveying sprocket, facilitating the effective clamping of the rotor housing by the clamping assemblies, realizing secondary positioning, and avoiding the shaking and offset of the rotor housing caused by the relative movement between the conveying tooling and the conveying sprocket during the magnetic sheet assembly, resulting in assembly errors and affecting the assembly efficiency and quality.

[0016] Furthermore, one end of the two clamping blocks facing each other is V-shaped.

[0017] The V-shaped end of the clamping block can naturally guide the centering of the rotor housing, which helps the rotor housing to be positioned quickly and accurately. At the same time, the V-shaped structure can be applied to the clamping of rotor housings of different specifications and sizes, eliminating the need for frequent replacement of clamping blocks and improving production efficiency.

[0018] Furthermore, a sliding assembly is provided between the clamping block and the end of the output shaft of the clamping cylinder. The sliding assembly includes a slide rail and a sliding seat, and the sliding seat is connected to the output shaft of the clamping cylinder.

[0019] With the sliding assembly as an intermediate transmission structure, moving along the slide rail is beneficial to ensuring the movement stability of the clamping block and preventing position deviation so that the rotor housing cannot be adjusted to the correct assembly position.

[0020] Furthermore, sliding assemblies are provided at the bottoms of both the S-pole feeding mechanism and the N-pole feeding mechanism. The sliding assemblies include slide rails and sliding seats, and the sliding seats are fixed to the bottoms of the feeding cylinders and the magnetic sheet placement bins.

[0021] The sliding assemblies facilitate adjusting the distances between the S-pole feeding mechanism and the N-pole feeding mechanism and the rotating head, which helps to adapt to multi-demand assembly according to the specifications of the rotating head and the rotor housing in actual production, enhancing the overall practicality of the device.

[0027] The following is a more detailed description through specific embodiments:

[0028] The reference numerals in the accompanying drawings of the specification include: support frame 1, rotor housing transfer mechanism 2, transfer sprocket 21, transfer tooling 22, support table 3, magnetic sheet mounting mechanism 4, magnetic sheet integration mechanism 41, sliding cylinder 411, rotating motor 412, rotating head 413, fixed groove 414, connecting block 415, S-pole feeding mechanism 42, N-pole feeding mechanism 43, magnetic sheet placement bin 44, feeding cylinder 45, strip hole 46, push block 47, glue application head 5, stop component 6, inductor 61, stop cylinder 62, stop seat 63, clamping component 7, clamping cylinder 71, clamping block 72, sliding component 8, slide rail 81, sliding seat 82, jacking assembly 9, jacking cylinder 91, transmission plate 92.

[0029] The embodiment is basically as shown in the attached Figures 1-5 As shown: A magnetic sheet mounting device for rotor assembly includes a support frame 1 and a rotor housing transfer mechanism 2 and a magnetic sheet mounting mechanism 4 provided on the support frame 1. The rotor housing transfer mechanism 2 includes a transfer tooling 22 and a transfer sprocket 21. There is a rolling friction between the transfer sprocket 21 and the transfer tooling 22, and the transfer sprocket 21 is driven by a motor to perform a rotary motion; a support table 3 is provided on the support frame 1, and the magnetic sheet mounting mechanism 4 is arranged on the support table 3. The magnetic sheet mounting mechanism 4 includes a magnetic sheet integration mechanism 41 and an S-pole feeding mechanism 42 and an N-pole feeding mechanism 43 distributed on both sides of the magnetic sheet integration mechanism 41.

[0030] The magnetic sheet integration mechanism 41 is used to pre-unify the arrangement of magnetic sheets. The magnetic sheet integration mechanism 41 includes a vertical sliding component and a rotating component. The vertical sliding component is a vertically arranged sliding cylinder 411, and the rotating component is a rotating motor 412. The rotating motor 412 is fixed on the output shaft of the sliding cylinder 411 through a connecting block 415. A rotating head 413 is detachably connected to the bottom of the rotating component, so as to facilitate replacing different specifications of rotating heads 413 according to actual production requirements to adapt to the production of different specifications of rotors; a plurality of pairs of fixed grooves 414 for accommodating magnetic sheets are evenly arranged on the outer periphery of the rotating head 413, and the rotating head 413 is made of a magnetic metal material.

[0031] The number of fixed slots 414 between the S-pole feeding mechanism 42 and the N-pole feeding mechanism 43 is odd. This effectively ensures that during the rotation of the rotating head 413, the magnetic sheets are installed into the rotor housing in an alternating arrangement of S-poles and N-poles, fundamentally eliminating the magnetic sheet arrangement errors caused by human negligence. This not only significantly reduces the defective rate but also ensures the assembly accuracy and product quality. Both the S-pole feeding mechanism 42 and the N-pole feeding mechanism 43 include a magnetic sheet placement bin 44 and a feeding cylinder 45. A strip-shaped hole 46 is opened on the side wall of the magnetic sheet placement bin 44 facing the feeding cylinder 45. A push block 47 is fixed on the output shaft of the feeding cylinder 45. The push block 47 is inserted into the magnetic sheet placement bin 44 through the strip-shaped hole 46 and slides along the strip-shaped hole 46 to push the magnetic sheet towards the rotating head 413.

[0032] A glue coating assembly for coating the outer side of the magnetic sheet is also installed on the support platform 3. The glue coating assembly is fixed between the magnetic sheet integration mechanism 41 and the N-pole feeding mechanism 43. The glue coating head 5 of the glue coating assembly is aligned with the fixed slot 414 on the rotating head 413, and the distance between the top of the glue coating head 5 and the bottom wall of the fixed slot 414 is equal to the thickness of the magnetic sheet. The installation position of the glue coating assembly is adjusted according to the thickness of the magnetic sheet. In this way, it is convenient to drive the magnetic sheet in the fixed slot 414 past the glue coating head 5 during the rotation of the rotating head 413, and the glue coating head 5 synchronously coats the outer side of the magnetic sheet, saving the separate glue coating process and improving production efficiency.

[0033] As Figure 4 shown, a stop component 6 for stopping the transfer tooling 22 is evenly arranged on the support frame 1. The stop component 6 includes an inductor 61, a stop cylinder 62, and a stop seat 63 arranged at the end of the output shaft of the stop cylinder 62. The induction signal of the inductor 61 is transmitted to the PLC program, and the stop cylinder 62 is controlled and driven by the PLC program. Through the cooperation of the inductor 61, the stop cylinder 62, and the stop seat 63, it is ensured that each transfer tooling 22 stops moving when it reaches below the rotating head 413 for the assembly process. Compared with the frequent start and stop of the entire transfer sprocket 21, which consumes time and energy and exacerbates the start and stop wear of components, intercepting the transfer tooling 22 by the stop component 6 can effectively ensure production continuity and be more economical.

[0034] As Figure 1 、 Figure 2 Combined with the figure shown, clamping components 7 are symmetrically arranged on both sides of the support frame 1. The clamping components 7 include a clamping cylinder 71 and a clamping block 72 connected to the end of the output shaft of the clamping cylinder 71. The opposite ends of the two clamping blocks 72 are V-shaped. The V-shaped design can better achieve the centering and positioning of the rotor housing. A sliding component 8 is arranged between the clamping block 72 and the end of the output shaft of the clamping cylinder 71. The sliding component 8 includes a slide rail 81 and a sliding seat 82. The sliding seat 82 is connected to the output shaft of the clamping cylinder 71. In this way, the stability of the movement of the clamping block 72 is improved, and the rotor housing is effectively clamped and positioned.

[0035] As Figure 5 shown, a jacking assembly 9 is provided below the rotating head 413 corresponding to the support frame 1. The jacking assembly 9 is used to jack up the conveying tooling 22 and the rotor housing upward. The jacking assembly 9 includes a jacking cylinder 91 fixed on the support frame 1. The end of the output shaft of the jacking cylinder 91 is connected to a transmission plate 92. The rotor housing is jacked up to between the clamping assemblies 7 on both sides by the jacking assembly 9, so that the conveying tooling 22 is separated from the conveying sprocket 21, facilitating the effective clamping of the rotor housing by the clamping assemblies 7, realizing secondary positioning, and avoiding the shaking and offset of the rotor housing caused by the relative movement between the conveying tooling 22 and the conveying sprocket 21 during the magnetic sheet assembly, resulting in assembly errors and affecting the assembly efficiency and quality.

[0036] Sliding assemblies 8 are provided at the bottoms of both the S-pole feeding mechanism 42 and the N-pole feeding mechanism 43. The sliding assemblies 8 include slide rails 81 and sliding seats 82. The sliding seats 82 are fixed to the bottoms of the feeding cylinders 45 and the magnetic sheet placement bins 44. The sliding assemblies 8 facilitate adjusting the distances of the S-pole feeding mechanism 42 and the N-pole feeding mechanism 43 from the rotating head 413, which helps to adapt to multi-demand assembly according to the specifications of the rotating head 413 and the rotor housing in actual production, improving the overall practicality of the device.

[0037] The specific implementation process is as follows:

[0038] In specific applications, the rotor housing with the partition frame installed is conveyed by the conveying sprocket 21 to the lower part of the magnetic sheet installation mechanism 4. The conveying sprocket 21 is driven by a motor to perform a rotary motion and drives the conveying tooling 22 and the rotor housing thereon to perform horizontal conveyance through rolling friction. When the conveying tooling 22 moves to the inductor 61, the inductor 61 transmits an induction signal to the PLC program. The PLC program sends a driving signal to the stop cylinder 62, and the stop cylinder 62 raises the stop seat 63 upward to make the rotor housing located directly below the rotating head 413. At the same time, the jacking cylinder 91 is started and jacks up the conveying tooling 22 and the rotor housing to between the two clamping assemblies 7, and the clamping block 72 is driven by the clamping cylinder 71 to clamp the rotor housing.

[0039] When the rotor housing is in place, the feeding cylinders 45 of the rotating electric machine 412, the S-pole feeding mechanism 42, and the N-pole feeding mechanism 43 are activated. The rotating electric machine 412 drives the rotating head 413 to rotate. The feeding cylinder 45 pushes the magnetic sheet into the fixing groove 414 through the pushing block 47. Each rotation amplitude of the rotating electric machine 412 is two fixing grooves 414. During the rotation process, the top of the glue application head 5 contacts the outer side of the magnetic sheet for glue application. Until after one full rotation, all the fixing grooves 414 on the rotating head 413 are adsorbed with magnetic sheets. Then, the sliding cylinder 411 drives the rotating head 413 to move downward so that the magnetic sheets are inserted into the partition frame to complete the installation of the magnetic sheets. After the installation of the magnetic sheets is completed, the sliding cylinder 411 drives the rotating head 413 to move upward to reset. The clamping cylinder 71, the lifting cylinder 91, and the stopping cylinder 62 all drive the output shafts to reset. The conveying tooling 22 falls on the conveying sprocket 21 again for rolling friction transmission.

[0040] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
