Description

Technical Field

[0001] The present application relates to the technical field of motor component assembly, and in particular to a brushless motor stator press-fitting device and press-fitting method. Background Art

[0002] In the traditional brushless motor stator press-fitting process of lawn mowing robots, the iron core stator is usually pressed in one go. Since the reserved wire ends of the iron core stator coil are not effectively guided and protected during the assembly process, the wire ends are easily pressed, pulled or squeezed by mistake, resulting in uneven arrangement and inconsistent length of the reserved wires, which in turn affects the overall assembly quality and subsequent electrical performance of the brushless motor. It also affects the press-fitting accuracy, resulting in deviations in the fit between the iron core stator and the motor base, further increasing the product defect rate and making it difficult to meet the production needs of high-quality brushless motors. Summary of the Invention

[0003] In order to improve the defects of traditional brushless motor stator press-fitting process of lawn mowing robot, in which the reserved wire ends of the iron core stator coil are easily pressed, pulled or squeezed by mistake, resulting in uneven arrangement of the reserved wires, inconsistent lengths, and insufficient assembly accuracy, the present application provides a brushless motor stator press-fitting device and press-fitting method.

[0004] The present application provides a brushless motor stator press-fitting device and press-fitting method using the following technical solutions: A brushless motor stator press-fitting device comprises a press-fitting base, a positioning base connected to the press-fitting base, a press-fitting guide mechanism movably inserted in the positioning base, a positioning guide column connected to the press-fitting base and inserted in the press-fitting guide mechanism, an elastic reset mechanism sleeved around the positioning guide column and located between the press-fitting base and the press-fitting guide mechanism, a downward pressing guide mechanism connected to the press-fitting base and located around the positioning base, a lower pressing plate sleeved around the downward pressing guide mechanism and slidably connected to the downward pressing guide mechanism, a pressing head mechanism connected to the lower pressing plate and aligned with the positioning base, a wire management guide mechanism movably inserted on the positioning base and connected to the press-fitting guide mechanism, and an iron core gluing mechanism connected to the positioning base and sleeved around the press-fitting guide mechanism. The upper end of the positioning seat is used to support the bottom of the iron core stator, the press-fitting guide mechanism supports the motor base, and the pressure head mechanism is used to press the motor base downward to make the motor base and the iron core stator have an interference fit. When the press-fitting guide mechanism drives the wire management guide mechanism to move downward, the wire management guide mechanism is used to drive the wire ends on the iron core stator to move downward.

[0005] By adopting the above technical solution, the upper end of the press-fitting guiding mechanism passes through the middle position of the iron core stator and is used to support the motor base. The lower pressing plate is used to drive the pressing head mechanism to move along the length direction of the downward pressing guiding mechanism. The pressing head mechanism is used to perform a downward pressing operation on the motor base, so that the motor base is in interference plug-in fit with the iron core stator under the action of the pressing head mechanism. The positioning and guiding column is used for the positioning and guiding of the press-fitting guiding mechanism, and the elastic reset mechanism is used to realize the automatic reset of the press-fitting guiding mechanism after press-fitting; the wire head of the wire on the iron core stator passes through the wire arranging guiding mechanism. When the press-fitting guiding mechanism moves downward, the wire arranging guiding mechanism moves downward synchronously, thereby driving the wire head to move downward, avoiding the risk of the wire head being mis-pressed, pulled or pinched during the press-fitting process; when the press-fitting guiding mechanism moves downward, the iron core gluing mechanism automatically glues the iron core stator through compression, ensuring the reliability and consistency of the press-fitting of the iron core stator and the motor base; the present application not only improves the automation and assembly accuracy of the press-fitting process, but also effectively avoids phenomena such as wire head damage and fitting deviation, reduces the product defect rate, and improves the overall assembly quality and production efficiency of the brushless motor.

[0006] Preferably, the positioning seat includes a positioning seat body connected to the press-fitting base, and a positioning support convex edge connected to the upper end of the positioning seat body and used to support the bottom of the iron core stator; guiding sliding grooves for the press-fitting guiding mechanism to be movably inserted are provided on both the positioning seat body and the positioning support convex edge.

[0007] By adopting the above technical solution, the iron core stator is placed on the positioning support convex edge, and the positioning support convex edge realizes reliable support for the bottom of the iron core stator, ensuring the stability and alignment accuracy of the iron core stator during the subsequent press-fitting process. The press-fitting guiding mechanism is movably inserted along the guiding sliding groove to realize the precise alignment and guiding of the motor base and the iron core stator, thereby improving the coordination degree of each component during the press-fitting operation, and at the same time reducing the assembly error caused by manual placement or positioning deviation. The present application ensures the stable positioning and precise guiding of the iron core stator during the press-fitting process, and effectively improves the overall assembly quality and product consistency.

[0008] Preferably, the press-fitting guiding mechanism includes a sealing cover bottom plate sleeved on the periphery of the positioning and guiding column and connected to the upper end of the elastic reset mechanism, a linear bearing connected to the sealing cover bottom plate and sleeved on the periphery of the positioning and guiding column, a guiding seat connected to the sealing cover bottom plate and sleeved on the periphery of the linear bearing, and a positioning convex block inserted into the guiding seat.

[0009] By adopting the above technical solution, the cover base plate serves as the bearing platform of the press-fitting guide mechanism and is connected to the elastic reset mechanism. After the press-fitting is completed, it automatically returns to its original position through elastic action. The linear bearing is sleeved on the side of the positioning guide column, so that the press-fitting guide mechanism can move smoothly and with low friction along a predetermined straight path, effectively avoiding shaking and deflection during the press-fitting process, and ensuring the accuracy of the plug-in alignment. The guide seat further enhances the stability and guiding effect of the structure. The positioning protrusion is used to limit the positioning of the motor base and prevent rotation. Through the cooperation of the above-mentioned structure, this application improves the smoothness and accuracy of the press-fitting operation, effectively reduces the errors caused by manual intervention, ensures the interference fit accuracy between the iron core stator and the motor base, and thus improves the assembly quality and production efficiency.

[0010] Preferably, the positioning seat body is further provided with a wire-management guide through-hole for connecting the guide slide groove with the external space, and a wire-management guide groove provided on the inner side wall of the wire-management guide through-hole and communicating with the wire-management guide through-hole; The wire guiding mechanism includes a wire guiding slider which is movably inserted in the wire guiding groove and connected to the press-fitting guiding mechanism, a wire sliding protrusion which is connected to the wire guiding slider and extends from the wire guiding through hole to the outside of the positioning seat body, a wire transmission rod connected to the wire sliding protrusion, and a wire end toggling ring which is connected to the end of the wire transmission rod, and the wire end toggling ring is used for allowing the wire ends on the iron core stator to pass through.

[0011] By adopting the above technical solution, the wire ends of the wires on the iron core stator pass through the wire end toggle ring. When the press-fitting guide mechanism moves downward and drives the wire management guide slider to move downward synchronously, the wire management guide slider drives the wire management sliding convex edge and the wire management transmission rod to move downward along the length direction of the wire management guide groove. The wire management transmission rod drives the wire end toggle ring to move downward. The wire end toggle ring can effectively pull and guide the coil wire ends, ensuring that the wire ends are always kept outside the positioning seat body during the entire press-fitting stage, avoiding the wire ends from being accidentally pressed, pulled or squeezed, effectively improving the neatness and length consistency of the wire ends, reducing the difficulty and error rate of manual wire management, thereby improving assembly efficiency and finished product consistency, and ensuring high-quality press-fitting of the brushless motor stator.

[0012] Preferably, the iron core gluing mechanism includes a gluing bracket connected to the positioning seat body, an annular gluing assembly connected to the gluing bracket and sleeved on the circumference of the press-fitting guide mechanism, a glue storage assembly connected to the press-fitting base and communicated with the annular gluing assembly, an airbag assembly movably inserted on the positioning seat body and connected to the glue storage assembly, and an airbag extrusion assembly located on the upper side of the airbag assembly and connected to the press-fitting guide mechanism; when the press-fitting guide mechanism moves downward, the press-fitting guide mechanism drives the airbag extrusion assembly to move downward and presses the airbag assembly downward.

[0013] By adopting the above technical solution, when the press-fitting guiding mechanism moves downward, the airbag extrusion assembly is driven to move downward synchronously and press down on the airbag assembly. After being squeezed, the airbag assembly inflates into the glue storage assembly, prompting the glue inside the glue storage assembly to be evenly ejected through the annular glue application assembly, achieving automatic, quantitative, and annular glue application to the insertion part of the iron core stator. The whole process is integrated into the press-fitting action, eliminating the need for manual glue application. This not only ensures the uniformity and coating efficiency of glue application but also enhances the bonding strength and reliability between the iron core stator and the coil, effectively reducing the inconsistent glue application and missed glue application caused by human factors, thereby further improving the consistency of brushless motor assembly and the reliability of the product.

[0014] Preferably, the positioning seat body is further provided with a glue application guiding through-hole for communicating the guiding chute with the external space, and a glue application guiding groove provided on the inner side wall of the wire arranging guiding through-hole and for the airbag extrusion assembly to be movably inserted. The airbag assembly includes an airbag body inserted into the glue application guiding groove and located below the airbag extrusion assembly, an intake check valve connected to the airbag body and arranged in the direction close to the elastic reset mechanism, a blowing conduit for connecting the airbag body and the glue storage assembly, and an outlet check valve connected to the blowing conduit.

[0015] By adopting the above technical solution, when the airbag extrusion assembly moves downward along the glue application guiding groove and applies a squeezing force to the airbag body, after being pressed, the airbag body sends gas into the glue storage assembly along the blowing conduit through the outlet check valve, prompting the glue to be accurately and evenly pushed to the glue application area. When the airbag body resets, external air enters the airbag body through the intake check valve; this application realizes the linkage of automatic inflation and deflation of the airbag body and quantitative glue delivery, enhancing the automation, sealing, and consistency of the glue application process, reducing human operation errors, and ensuring the bonding effect of the combination of the iron core stator and the coil and the assembly quality of the product.

[0016] Preferably, the glue storage assembly includes a storage tank connected to the blowing conduit, a guide pipe inserted into the bottom of the storage tank and connected to the annular glue application assembly, and a check valve arranged on the upper side of the storage tank and connected to the guide pipe.

[0017] By adopting the above technical solution, during the press-fitting and glue application process, when the airbag assembly injects gas into the storage tank through the blowing conduit, the glue in the storage tank is pressed and flows along the guide pipe to the annular glue application assembly, realizing the quantitative output of the glue. The check valve is used to prevent the glue from flowing back, ensuring that the glue only enters the guide pipe unidirectionally. This application drives the automatic and stable output of the glue through air pressure, enhancing the glue application efficiency and uniformity, and effectively avoiding the risks of glue leakage and backflow.

[0018] Preferably, the annular glue coating assembly includes an annular pipe connected to the glue coating bracket, a soft glue material guide nozzle connected to the annular pipe and extending in the direction facing the pressing guide mechanism, and a glue coating brush connected to the inner side wall of the annular pipe and extending in the direction facing the pressing guide mechanism. The soft glue material guide nozzle and the glue coating brush are arranged in an array along the circumference of the annular pipe.

[0019] By adopting the above technical solution, the soft glue guide nozzle and the glue brush are inserted between the iron core stator and the motor base and are located above the iron core stator. During the gluing process, the glue in the glue storage assembly is distributed to multiple soft glue guide nozzles through the annular pipe, so as to realize annular, multi-point synchronous glue spraying on the upper side of the iron core stator. When the iron core stator and the motor base are pressed together, the iron core stator and the motor base are pressed to maintain a gap, the elastic reset mechanism is reset and drives the pressing guide mechanism to move upward, and the pressing guide mechanism drives the pressed iron core stator and the motor base to move upward synchronously. The glue brushes distributed on the inner circumference of the annular pipe will stick to the upper side wall and the peripheral side wall of the iron core stator in turn, and cooperate with the sprayed glue to perform secondary uniform coating and spreading, which effectively improves the uniformity and coverage of the glue distribution, avoids the problems of missing coating and local excessive thickness, and improves the bonding reliability and consistency of the iron core stator and the coil, and improves the overall quality and production efficiency of the pressing.

[0020] Preferably, the positioning seat further comprises an iron core glue coating groove body located below the annular glue coating component and sleeved on the peripheral side of the positioning support protrusion, and the iron core glue coating groove body is used for inserting the bottom of the iron core stator.

[0021] By adopting the above technical solution, the iron core gluing trough is used to receive the glue overflowed during spraying by the soft glue guide nozzle, and the iron core stator is inserted into the iron core gluing trough so that the bottom of the iron core stator is coated with glue. The setting of the iron core gluing trough can not only prevent the glue from flowing out, but also can coat the bottom of the iron core stator with glue, further improving the reliability of the gluing operation and the utilization rate of glue, and effectively improving the overall assembly accuracy of the pressing device and the consistency of the finished product.

[0022] A brushless motor stator press-fitting method includes the brushless motor stator press-fitting device described above, and further includes a bearing press-fitting positioning seat, a bearing pressing convex edge connected to the middle position of the bearing press-fitting positioning seat, an iron core stator positioning sleeve sleeved on the circumference of the bearing pressing convex edge, a bearing press-fitting guide column inserted at the middle position of the bearing pressing convex edge, and a bearing positioning pressure head provided above the bearing pressing convex edge and used for movably plugging and cooperating with the bearing press-fitting guide column, the bearing press-fitting positioning seat is provided with an iron core positioning groove, the bearing pressing convex edge, the iron core stator positioning sleeve and the bearing press-fitting guide column are all inserted into the iron core positioning groove; and further includes the following steps: S1: Place the iron core stator on the upper side of the positioning seat and sleeved on the outer wall of the press-fitting guiding mechanism, and insert the motor base on the press-fitting guiding mechanism; S2: Pass the wire end of the wire on the iron core stator through the wire arranging guiding mechanism; S3: The lower pressing plate moves downward and drives the pressing head mechanism to move downward synchronously. The pressing head mechanism presses down the motor base, the motor base presses down the press-fitting guiding mechanism, the press-fitting guiding mechanism moves downward along the length direction of the positioning guiding column and compresses the elastic reset mechanism. The motor base and the iron core stator are in interference plug-in fit to form a primary plug-in press fit; S4: The press-fitting guiding mechanism drives the wire arranging guiding mechanism to move downward, and the wire arranging guiding mechanism drives the wire end of the wire on the iron core stator to move downward; S5: The press-fitting guiding mechanism presses down the iron core gluing mechanism, and the iron core gluing mechanism sprays glue onto the iron core stator; S6: Remove the preliminarily press-fitted motor base and iron core stator from the positioning seat, place the two bearings at the middle positions on the upper and lower sides of the motor base respectively, and then insert the preliminarily press-fitted motor base and iron core stator into the iron core positioning groove; S7: The two bearings, the motor base and the iron core stator are all movably sleeved on the periphery of the bearing press-fitting guiding column. The bearing pressing convex edge is used to press the bearing on the lower side of the motor base, and the iron core stator positioning sleeve is used to press the preliminarily press-fitted iron core stator; S8: The bearing positioning press head moves downward and makes the bearing press-fitting guiding column movably inserted into the bearing positioning press head. The lower end of the bearing positioning press head presses down the bearing on the upper side of the motor base. The bearing positioning press head and the bearing pressing convex edge cooperate to press the two bearings on the motor base to form a secondary plug-in press fit; The bearing positioning press head and the iron core stator positioning sleeve cooperate to tightly press the motor base and the iron core stator synchronously to form a tertiary plug-in press fit.

[0023] By adopting the above technical solution, first, the iron core stator and the motor base are sequentially assembled on the positioning seat and the press-fitting guiding mechanism. The wire head is smoothly guided by the wire management guiding mechanism. The lower pressing plate and the pressing head mechanism cooperate to press the motor base downward, realizing the interference plug-in fit between the motor base and the iron core stator, completing the first-level pressing, and protecting the wire head by the synchronous downward movement of the wire management guiding mechanism. Then, the press-fitting guiding mechanism further moves downward to trigger the iron core gluing mechanism, automatically and evenly spraying glue to complete the gluing operation. Subsequently, the preliminarily pressed components are removed and two bearings are assembled. The whole is inserted into the iron core positioning groove. The bearing positioning pressing head moves downward, and the lower end of the bearing positioning pressing head presses the bearing on the upper side of the motor base. With the cooperation of the bearing positioning pressing head and the bearing top pressing convex edge, the precise pressing of the two bearings is completed, realizing the second-level plug-in pressing. The bearing positioning pressing head and the iron core stator positioning sleeve cooperate to synchronously press the motor base and the iron core stator, forming the third-level plug-in pressing. Through the step-by-step precise cooperation and automatic movement of each structural part in this application, the assembly accuracy, structural stability and consistency between the iron core stator, the motor base and the bearings are improved, effectively reducing the risks of wire head damage, pressing deviation and assembly defect rate, and improving the finished product quality of the brushless motor assembly.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. A brushless motor stator press-fitting device, wherein the upper end of the press-fitting guiding mechanism passes through the middle position of the iron core stator and is used to support the motor base. The lower pressing plate is used to drive the pressing head mechanism to move along the length direction of the downward pressing guiding mechanism. The pressing head mechanism is used to perform a downward pressing operation on the motor base, so that the motor base realizes an interference plug-in fit with the iron core stator under the action of the pressing head mechanism. The positioning and guiding column is used for the positioning and guiding of the press-fitting guiding mechanism. The elastic reset mechanism is used to realize the automatic reset of the press-fitting guiding mechanism after pressing. The wire head of the wire on the iron core stator passes through the wire management guiding mechanism. When the press-fitting guiding mechanism moves downward, the wire management guiding mechanism moves downward synchronously, thereby driving the wire head to move downward, avoiding the risks of the wire head being mis-pressed, pulled or pinched during the press-fitting process. When the press-fitting guiding mechanism moves downward, the iron core gluing mechanism automatically glues the iron core stator through compression, ensuring the reliability and consistency of the press-fitting between the iron core stator and the motor base. This application not only improves the automation and assembly accuracy of the press-fitting process, but also effectively avoids phenomena such as wire head damage and fitting deviation, reduces the product defect rate, and improves the overall assembly quality and production efficiency of the brushless motor. 2. A brushless motor stator press-fitting device. When the press-fitting guiding mechanism moves downward, the airbag extrusion assembly is driven to move downward synchronously and press down on the airbag assembly. After being squeezed, the airbag assembly inflates into the glue storage assembly, prompting the glue inside the glue storage assembly to be evenly sprayed through the annular glue coating assembly, realizing automatic, quantitative, and annular glue coating on the insertion part of the iron core stator. The whole process is integrated into the press-fitting action, eliminating the need for separate manual glue application. This not only ensures the uniformity and coating efficiency of glue application but also enhances the bonding strength and reliability between the iron core stator and the coil, effectively reducing the inconsistent glue application and missed glue application caused by human factors, thereby further improving the consistency of brushless motor assembly and the reliability of products. 3. A brushless motor stator press-fitting method. First, the iron core stator and the motor base are sequentially assembled on the positioning seat and the press-fitting guiding mechanism. The wire head is smoothly guided by the wire management guiding mechanism. The lower pressing plate and the pressing head mechanism cooperate to press down the motor base, realizing the interference fit between the motor base and the iron core stator and completing the first-level press fit. The wire head is protected by the synchronous downward movement of the wire management guiding mechanism. Then, the press-fitting guiding mechanism moves further downward to trigger the iron core glue coating mechanism, which automatically sprays glue evenly to complete the glue coating operation. Subsequently, the preliminarily press-fitted components are removed and two bearings are assembled. The whole is inserted into the iron core positioning groove. The bearing positioning pressing head moves downward, and the lower end of the bearing positioning pressing head presses down the bearing on the upper side of the motor base. With the cooperation of the bearing positioning pressing head and the bearing top pressing convex edge, the precise press-fitting of the two bearings is completed, realizing the second-level insertion press fit. The bearing positioning pressing head and the iron core stator positioning sleeve cooperate to synchronously clamp the motor base and the iron core stator, forming the third-level insertion press fit. Through the step-by-step precise cooperation and automatic movement of each structural component in this application, the assembly accuracy, structural stability, and consistency between the iron core stator, the motor base, and the bearings are improved.

[0031] The following is combined with Figures 1 to 5 This application is described in further detail.

[0032] The present application discloses a brushless motor stator press-fitting device and press-fitting method. Figure 1 A brushless motor stator press-fitting device comprises a press-fitting base 1, a positioning base 2 connected to the press-fitting base 1, a press-fitting guide mechanism 3 movably inserted in the positioning base 2, a positioning guide column 4 connected to the press-fitting base 1 and inserted in the press-fitting guide mechanism 3, an elastic reset mechanism 5 sleeved around the positioning guide column 4 and located between the press-fitting base 1 and the press-fitting guide mechanism 3, a downward pressing guide mechanism 6 connected to the press-fitting base 1 and located around the positioning base 2, a lower pressing plate 7 sleeved around the downward pressing guide mechanism 6 and slidably connected to the downward pressing guide mechanism 6, a pressing head mechanism 8 connected to the lower pressing plate 7 and aligned with the positioning base 2, a wire management guide mechanism 9 movably inserted on the positioning base 2 and connected to the press-fitting guide mechanism 3, and an iron core gluing mechanism 10 connected to the positioning base 2 and sleeved around the press-fitting guide mechanism 3; The upper end of the positioning seat 2 is used to support the bottom of the iron core stator. The press-fitting guiding mechanism 3 supports the motor base. The pressing head mechanism 8 is used to press down the motor base so that the motor base and the iron core stator are in interference plug-in fit. When the press-fitting guiding mechanism 3 drives the wire arranging guiding mechanism 9 to move downward, the wire arranging guiding mechanism 9 is used to drive the wire heads of the wires on the iron core stator to move downward.

[0033] The upper end part of the press-fitting guiding mechanism 3 of the present application passes through the middle position of the iron core stator and is used to support the motor base. The lower pressing plate 7 is used to drive the pressing head mechanism 8 to move along the length direction of the downward pressing guiding mechanism 6. The pressing head mechanism 8 is used to perform a downward pressing operation on the motor base, so that the motor base is in interference plug-in fit with the iron core stator under the action of the pressing head mechanism 8. The positioning and guiding column 4 is used for the positioning and guiding of the press-fitting guiding mechanism 3. The elastic reset mechanism 5 is used to realize the automatic reset of the press-fitting guiding mechanism 3 after press-fitting; the wire heads of the wires on the iron core stator pass through the wire arranging guiding mechanism 9. When the press-fitting guiding mechanism 3 moves downward, the wire arranging guiding mechanism 9 moves downward synchronously, thereby driving the wire heads to move downward, avoiding the risks of the wire heads being mis-pressed, pulled or squeezed during the press-fitting process; when the press-fitting guiding mechanism 3 moves downward, the iron core gluing mechanism 10 automatically glues the iron core stator through compression, ensuring the reliability and consistency of the press-fitting of the iron core stator and the motor base; the present application not only improves the automation and assembly accuracy of the press-fitting process, but also effectively avoids phenomena such as wire head damage and fitting deviation, reduces the product defect rate, and improves the overall assembly quality and production efficiency of the brushless motor.

[0034] The present application also discloses that the lower pressing plate 7 is driven to move downward by a cylinder or a hydraulic cylinder (not shown in the figure); the elastic reset mechanism 5 is preferably a spring; the downward pressing guiding mechanism 6 is preferably a guiding slide bar.

[0035] Further, as Figure 1 shown, the positioning seat 2 includes a positioning seat body 21 connected to the press-fitting base 1, and a positioning support convex edge 22 connected to the upper end of the positioning seat body 21 and used to support the bottom of the iron core stator; guiding chute 23 for the press-fitting guiding mechanism 3 to movably insert is provided on both the positioning seat body 21 and the positioning support convex edge 22.

[0036] The iron core stator of the present application is used to be placed on the positioning support convex edge 22, and the reliable support of the bottom of the iron core stator is realized by the positioning support convex edge 22, ensuring the stability and alignment accuracy of the iron core stator in the subsequent press-fitting process. The press-fitting guiding mechanism 3 movably inserts along the guiding chute 23 to realize the precise alignment and guiding of the motor base and the iron core stator, thereby improving the coordination degree of each component during the press-fitting operation, and at the same time reducing the assembly error caused by manual placement or positioning deviation. The present application ensures the stable positioning and precise guiding of the iron core stator during the press-fitting process, and effectively improves the overall assembly quality and product consistency.

[0037] Even further, asFigure 1 As shown in the figure, the press-fitting guiding mechanism 3 includes a cover bottom plate 31 sleeved on the peripheral side of the positioning and guiding column 4 and connected to the upper end of the elastic reset mechanism 5, a linear bearing 32 connected to the cover bottom plate 31 and sleeved on the peripheral side of the positioning and guiding column 4, a guiding seat 33 connected to the cover bottom plate 31 and sleeved on the peripheral side of the linear bearing 32, and a positioning convex block 34 inserted into the guiding seat 33.

[0038] In this application, the cover bottom plate 31 of the present application serves as the bearing platform of the press-fitting guiding mechanism 3 and is connected to the elastic reset mechanism 5. After the press-fitting is completed, it realizes automatic return through the elastic action. The linear bearing 32 is sleeved on the peripheral side of the positioning and guiding column 4, enabling the press-fitting guiding mechanism 3 to move smoothly and with low friction along a predetermined straight path, effectively avoiding shaking and skew during the press-fitting process, ensuring the accuracy of the insertion alignment. The guiding seat 33 further enhances the structural stability and guiding effect. The positioning convex block 34 is used for limiting and positioning the motor base and preventing rotation. Through the cooperation of the above structures in this application, the smoothness and accuracy of the press-fitting operation are improved, the error caused by manual intervention is effectively reduced, the interference fit accuracy between the iron core stator and the motor base is ensured, and thus the assembly quality and production efficiency are improved.

[0039] As Figure 1 shown, the present application also discloses that a limiting convex edge 211 which is in top pressure fit with the upper side edge of the cover bottom plate 31 is provided inside the positioning seat body 21.

[0040] In the present invention, during the press-fitting process, the cover bottom plate 31 moves downward and compresses the elastic reset mechanism 5. After the press-fitting is completed, the pressing head mechanism 8 moves upward, the elastic reset mechanism 5 resets and presses the cover bottom plate 31 upward. When the upper side edge of the cover bottom plate 31 moves upward to a preset position, the upper side edge of the cover bottom plate 31 and the limiting convex edge 211 have a top pressure fit, thereby effectively restricting and positioning the upward movement stroke of the press-fitting guiding mechanism 3 and preventing the press-fitting guiding mechanism 3 from detaching from the positioning seat 2. This application can not only accurately control the movement stroke during the press-fitting process, improve the stability and controllability of the press-fitting operation, but also ensure the assembly accuracy of the iron core stator and the motor base, and reduce the error rate and defect rate during the press-fitting process.

[0041] Specifically, as Figure 2 and Figure 3 shown, a wire management guiding through hole 24 for communicating the guiding chute 23 with the external space is further provided on the positioning seat body 21, and a wire management guiding groove 25 which is communicated with the wire management guiding through hole 24 is provided on the inner side wall of the wire management guiding through hole 24; The wire guiding mechanism 9 includes a wire guiding slider 91 which is movably inserted into the wire guiding groove 25 and connected to the press-fitting guiding mechanism 3, a wire guiding sliding protrusion 92 which is connected to the wire guiding slider 91 and extends from the wire guiding through hole 24 to the outside of the positioning seat body 21, a wire guiding transmission rod 93 which is connected to the wire guiding sliding protrusion 92, and a wire end moving ring 94 which is connected to the end of the wire guiding transmission rod 93. The wire end moving ring 94 is used for allowing the wire ends of the wires on the iron core stator to pass through.

[0042] The ends of the wires on the iron core stator of the present application pass through the wire end toggle ring 94. When the press-fitting guide mechanism 3 moves downward and drives the wire management guide slider 91 to move downward synchronously, the wire management guide slider 91 drives the wire management sliding protrusion 92 and the wire management transmission rod 93 to move downward along the length direction of the wire management guide groove 25. The wire management transmission rod 93 drives the wire end toggle ring 94 to move downward. The wire end toggle ring 94 can effectively pull and guide the coil wire ends, ensuring that the wire ends are always kept outside the positioning seat body 21 during the entire press-fitting stage, avoiding the wire ends from being accidentally pressed, pulled or squeezed, effectively improving the neatness and length consistency of the wire end arrangement, reducing the difficulty and error rate of manual wire management, thereby improving assembly efficiency and finished product consistency, and ensuring high-quality press-fitting of the brushless motor stator.

[0043] The wire management guide slider 91 is connected to the cover bottom plate 31 .

[0044] More specifically, if Figure 2 As shown, the iron core gluing mechanism 10 includes a gluing bracket 101 connected to the positioning seat body 21, an annular gluing component 102 connected to the gluing bracket 101 and sleeved on the side of the press-fitting guide mechanism 3, a glue storage component 103 connected to the press-fitting base 1 and connected to the annular gluing component 102, an airbag component 104 movably inserted on the positioning seat body 21 and connected to the glue storage component 103, and an airbag extrusion component 105 located on the upper side of the airbag component 104 and connected to the press-fitting guide mechanism 3; when the press-fitting guide mechanism 3 moves downward, the press-fitting guide mechanism 3 drives the airbag extrusion component 105 to move downward and presses the airbag component 104 downward.

[0045] In the present application, when the press-fitting guide mechanism 3 moves downward, the airbag extrusion component 105 is driven to move downward synchronously and press the airbag component 104 downward. After being squeezed, the airbag component 104 inflates into the glue storage component 103, prompting the glue inside the glue storage component 103 to be evenly sprayed out through the annular gluing component 102, thereby realizing automatic, quantitative and annular gluing of the core stator plug-in parts. The entire process is integrated into the press-fitting action, and no separate manual gluing is required, which not only ensures the uniformity and coating efficiency of the gluing, but also improves the bonding strength and reliability of the core stator and the coil, effectively reducing the gluing inconsistency and missing gluing caused by human factors, thereby further improving the consistency of brushless motor assembly and product reliability.

[0046] The airbag extrusion assembly 105 is connected to the cover bottom plate 31.

[0047] In addition, as Figure 2 shown, the positioning seat body 21 is further provided with a glue application guiding through-hole 26 for communicating the guiding chute 23 with the external space, and a glue application guiding groove 27 provided on the inner side wall of the wire arranging guiding through-hole 24 and for the airbag extrusion assembly 105 to be movably inserted; The airbag assembly 104 includes an airbag body 1041 inserted into the glue application guiding groove 27 and located below the airbag extrusion assembly 105, an intake one-way valve 1042 connected to the airbag body 1041 and arranged in the direction close to the elastic reset mechanism 5, a blowing conduit 1043 for connecting the airbag body 1041 and the glue storage assembly 103, and an outlet one-way valve 1044 connected to the blowing conduit 1043.

[0048] In this application, when the airbag extrusion assembly 105 moves downward along the glue application guiding groove 27 and applies an extrusion force to the airbag body 1041, after the airbag body 1041 is pressed, the gas is sent into the glue storage assembly 103 along the blowing conduit 1043 through the outlet one-way valve 1044, so as to promote the glue to be accurately and evenly pushed to the glue application area. When the airbag body 1041 resets, the external air enters the airbag body 1041 through the intake one-way valve 1042; this application realizes the linkage of the automatic inflation and deflation of the airbag body 1041 and the quantitative delivery of the glue, improves the automation, sealing performance and consistency of the glue application process, reduces the manual operation error, and ensures the bonding effect of the iron core stator and the coil combination and the product assembly quality.

[0049] The airbag body 1041 is preferably an elastic reset airbag and can automatically reset when the compression pressure is removed.

[0050] And, as Figure 2 shown, the glue storage assembly 103 includes a storage tank 1031 connected to the blowing conduit 1043, a guiding pipeline 1032 inserted into the bottom of the storage tank 1031 and connected to the annular glue application assembly 102, and a check valve 1033 arranged on the upper side of the storage tank 1031 and connected to the guiding pipeline 1032.

[0051] In this application, during the press-fitting and glue application process, when the airbag assembly 104 injects gas into the storage tank 1031 through the blowing conduit 1043, the glue in the storage tank 1031 is pressed and flows along the guiding pipeline 1032 to the annular glue application assembly 102, realizing the quantitative output of the glue. The check valve 1033 is used to prevent the glue from flowing back, ensuring that the glue only enters the guiding pipeline 1032 unidirectionally. This application realizes the automatic and stable output of the glue driven by air pressure, improves the glue application efficiency and uniformity, and effectively avoids the risks of glue leakage and backflow.

[0052] Furthermore, if Figure 2 As shown, the annular glue coating assembly 102 includes an annular pipe 1021 connected to the glue coating bracket 101, a soft glue material guide nozzle 1022 connected to the annular pipe 1021 and extending in the direction facing the pressing guide mechanism 3, and a glue coating brush 1023 connected to the inner wall of the annular pipe 1021 and extending in the direction facing the pressing guide mechanism 3. The soft glue material guide nozzle 1022 and the glue coating brush 1023 are arranged in an array along the circumferential side of the annular pipe 1021.

[0053] The soft glue guide nozzle 1022 and the glue brush 1023 of the present application are inserted between the iron core stator and the motor base and are located above the iron core stator. During the gluing process, the glue in the glue storage component 103 is distributed to multiple soft glue guide nozzles 1022 through the annular pipe 1021, realizing annular, multi-point synchronous glue spraying on the upper side of the iron core stator. When the iron core stator and the motor base are pressed together, the iron core stator and the motor base are pressed to maintain a gap, the elastic reset mechanism 5 is reset and drives the press-fitting guide mechanism 3 moves upward, the press-fitting guide mechanism 3 drives the pressed core stator and motor base to move upward synchronously, and the glue-coating brushes 1023 distributed on the inner circumference of the annular pipe 1021 will successively stick to the upper side wall and the peripheral side wall of the core stator, and cooperate with the sprayed glue to perform secondary uniform coating and spreading, which effectively improves the uniformity and coverage of the glue distribution, avoids the problems of missing coating and local excessive thickness, and improves the bonding reliability and consistency of the core stator and the coil, and improves the overall quality and production efficiency of press-fitting.

[0054] Furthermore, if Figure 2 and Figure 3 As shown, the positioning seat 2 also includes an iron core glue coating groove 28 located below the annular glue coating component 102 and sleeved on the side of the positioning support protrusion 22. The iron core glue coating groove 28 is used for inserting the bottom of the iron core stator.

[0055] The core gluing trough 28 of the present application is used to receive the glue overflowed during spraying by the soft glue guide nozzle 1022. The core stator is inserted into the core gluing trough 28 so that the bottom of the core stator is coated with glue. The setting of the core gluing trough 28 can not only prevent the glue from flowing out, but also can coat the bottom of the core stator with glue, further improving the reliability of the gluing operation and the utilization rate of glue, and effectively improving the overall assembly accuracy of the pressing device and the consistency of the finished product.

[0056] Specifically, if Figure 4 and Figure 5As shown in the figure, the present application also discloses a method for press-fitting a brushless motor stator, including a brushless motor stator press-fitting device, which further includes a bearing press-fitting positioning seat 11, a bearing pressing convex edge 12 connected to the middle position of the bearing press-fitting positioning seat 11, a core stator positioning sleeve 13 sleeved on the circumferential side of the bearing pressing convex edge 12, a bearing press-fitting guiding column 14 inserted into the middle position of the bearing pressing convex edge 12, and a bearing positioning press head 15 arranged above the bearing pressing convex edge 12 and used for movably inserting and mating with the bearing press-fitting guiding column 14. A core positioning groove 16 is provided on the bearing press-fitting positioning seat 11, and the bearing pressing convex edge 12, the core stator positioning sleeve 13 and the bearing press-fitting guiding column 14 are all inserted into the core positioning groove 16. The method further includes the following steps: S1: Place the core stator on the upper side of the positioning seat 2 and sleeve it on the outer wall of the press-fitting guiding mechanism 3, and insert the motor base into the press-fitting guiding mechanism 3; S2: Pass the lead wire of the wire on the core stator through the wire arranging guiding mechanism 9; S3: The lower pressing plate 7 moves downward and drives the pressing head mechanism 8 to move downward synchronously. The pressing head mechanism 8 presses down the motor base, and the motor base presses down the press-fitting guiding mechanism 3. The press-fitting guiding mechanism 3 moves downward along the length direction of the positioning guiding column 4 and compresses the elastic reset mechanism 5. The motor base and the core stator are press-fitted with interference to form a first-level plug-in press fit; S4: The press-fitting guiding mechanism 3 drives the wire arranging guiding mechanism 9 to move downward, and the wire arranging guiding mechanism 9 drives the lead wire of the wire on the core stator to move downward; S5: The press-fitting guiding mechanism 3 presses down the core gluing mechanism 10, and the core gluing mechanism 10 sprays glue onto the core stator; S6: Remove the preliminarily press-fitted motor base and core stator from the positioning seat 2, place the two bearings at the middle positions on the upper and lower sides of the motor base respectively, and then insert the preliminarily press-fitted motor base and core stator into the core positioning groove 16; S7: The two bearings, the motor base and the core stator are all movably sleeved on the circumferential side of the bearing press-fitting guiding column 14. The bearing pressing convex edge 12 is used to press the bearing on the lower side of the motor base, and the core stator positioning sleeve 13 is used to press the preliminarily press-fitted core stator; S8: The bearing positioning press head 15 moves downward and makes the bearing press-fitting guiding column 14 movably inserted into the bearing positioning press head 15. The lower end of the bearing positioning press head 15 presses the bearing on the upper side of the motor base. The bearing positioning press head 15 and the bearing pressing convex edge 12 cooperate to press-fit the two bearings on the motor base to form a second-level plug-in press fit; The bearing positioning press head 15 and the core stator positioning sleeve 13 cooperate to synchronously press the motor base and the core stator tightly to form a third-level plug-in press fit.

[0057] In this application, the iron core stator and the motor base are first assembled on the positioning seat 2 and the press-fitting guiding mechanism 3 in sequence. The wire ends are smoothly guided by the wire management guiding mechanism 9. The lower pressing plate 7 and the pressing head mechanism 8 cooperate to press down the motor base, realizing the interference plug-in fit between the motor base and the iron core stator, completing the first-level pressing. And the wire ends are protected by the synchronous downward movement of the wire management guiding mechanism 9. Then, the press-fitting guiding mechanism 3 further moves downward to trigger the iron core glue application mechanism 10, which automatically sprays glue evenly to complete the glue application operation. Subsequently, the preliminarily press-fitted components are removed and two bearings are assembled. The whole is inserted into the iron core positioning groove 16. The bearing positioning pressing head 15 moves downward, and the lower end of the bearing positioning pressing head 15 presses the bearing on the upper side of the motor base. With the cooperation of the bearing positioning pressing head 15 and the bearing pressing convex edge 12, the precise press-fitting of the two bearings is completed, realizing the second-level plug-in pressing. The bearing positioning pressing head 15 and the iron core stator positioning sleeve 13 cooperate to synchronously press the motor base and the iron core stator tightly, forming the third-level plug-in pressing. Through the step-by-step precise cooperation and automatic movement of each structural part, this application improves the assembly accuracy, structural stability and consistency between the iron core stator, the motor base and the bearings, effectively reduces the wire end damage, press-fitting deviation and assembly defect rate, and improves the finished product quality of the brushless motor assembly.

[0058] The implementation principle of an embodiment of a brushless motor stator press-fitting device and a press-fitting method in this application is as follows: For a brushless motor stator press-fitting device, the upper end of the press-fitting guiding mechanism 3 passes through the middle position of the iron core stator and is used to support the motor base. The lower pressing plate 7 is used to drive the pressing head mechanism 8 to move along the length direction of the downward pressing guiding mechanism 6. The pressing head mechanism 8 is used to perform a downward pressing operation on the motor base, so that the motor base realizes an interference plug-in fit with the iron core stator under the action of the pressing head mechanism 8. The positioning and guiding column 4 is used for the positioning and guiding of the press-fitting guiding mechanism 3. The elastic reset mechanism 5 is used to realize the automatic reset of the press-fitting guiding mechanism 3 after press-fitting. The wire ends of the wire on the iron core stator pass through the wire management guiding mechanism 9. When the press-fitting guiding mechanism 3 moves downward, the wire management guiding mechanism 9 moves downward synchronously, thereby driving the wire ends to move downward, avoiding the risk of the wire ends being mis-pressed, pulled or squeezed during the press-fitting process. When the press-fitting guiding mechanism 3 moves downward, the iron core glue application mechanism 10 automatically applies glue to the iron core stator through compression, ensuring the reliability and consistency of the press-fitting between the iron core stator and the motor base. This application not only improves the automation and assembly accuracy of the press-fitting process, but also effectively avoids phenomena such as wire end damage and fitting deviation, reduces the product defect rate, and improves the overall assembly quality and production efficiency of the brushless motor. When the press-fitting guiding mechanism 3 moves downward, the airbag extrusion assembly 105 is driven to move downward synchronously and presses down the airbag assembly 104. After being extruded, the airbag assembly 104 inflates into the glue storage assembly 103, prompting the glue inside the glue storage assembly 103 to be evenly ejected through the annular glue coating assembly 102, realizing automatic, quantitative, and annular glue coating on the insertion part of the iron core stator. The whole process is integrated into the press-fitting action, without the need for separate manual glue application. This not only ensures the uniformity and coating efficiency of glue application, but also improves the bonding strength and reliability between the iron core stator and the coil, effectively reducing the inconsistent glue application and missed coating phenomena caused by human factors, thereby further improving the consistency of brushless motor assembly and the reliability of products; A method for press-fitting a brushless motor stator. First, the iron core stator and the motor base are sequentially assembled on the positioning seat 2 and the press-fitting guiding mechanism 3. The wire head is smoothly guided by the wire management guiding mechanism 9. The lower pressing plate 7 and the pressing head mechanism 8 cooperate to press down the motor base, realizing the interference insertion fit between the motor base and the iron core stator, completing the first-level pressing, and protecting the wire head by synchronously moving down the wire management guiding mechanism 9. Then, the press-fitting guiding mechanism 3 further moves downward to trigger the iron core glue coating mechanism 10, automatically spraying glue evenly to complete the glue coating operation; Subsequently, the preliminarily pressed components are removed and two bearings are assembled, and the whole is inserted into the iron core positioning groove 16. The bearing positioning pressing head 15 moves downward, and the bearing on the upper side of the motor base is pressed by the lower end of the bearing positioning pressing head 15. With the cooperation of the bearing positioning pressing head 15 and the bearing top pressing convex edge 12, the precise press-fitting of the two bearings is completed, realizing the second-level insertion and pressing. The bearing positioning pressing head 15 and the iron core stator positioning sleeve 13 cooperate to synchronously press the motor base and the iron core stator tightly, forming the third-level insertion and pressing. Through the step-by-step precise cooperation and automatic movement of each structural part in this application, the assembly accuracy, structural stability, and consistency between the iron core stator, the motor base, and the bearings are improved, effectively reducing wire head damage, press-fitting deviation, and assembly defect rate, and improving the finished product quality of brushless motor assembly.
