[0063] The wire arrangement guide slider 91 is connected with the cover bottom plate 31.

[0064] More specifically, as shown in Figure 2 The core gluing mechanism 10 comprises a gluing support 101 connected with the positioning seat body 21, an annular gluing assembly 102 connected with the gluing support 101 and sleeved on the side of the pressing arrangement guide mechanism 3, a glue storage assembly 103 connected with the pressing base 1 and communicated with the annular gluing assembly 102, an air bag assembly 104 movably inserted into the positioning seat body 21 and connected with the glue storage assembly 103, and an air bag extrusion assembly 105 located on the upper side of the air bag assembly 104 and connected with the pressing arrangement guide mechanism 3. When the pressing arrangement guide mechanism 3 moves downward, the pressing arrangement guide mechanism 3 drives the air bag extrusion assembly 105 to move downward and press the air bag assembly 104.

[0065] When the pressing arrangement guide mechanism 3 moves downward, the air bag extrusion assembly 105 is driven to move downward synchronously and press the air bag assembly 104, the air bag assembly 104 is inflated into the glue storage assembly 103 after being extruded, the glue in the glue storage assembly 103 is uniformly sprayed out through the annular gluing assembly 102, the automatic, quantitative and annular gluing of the core stator insertion part is realized, the whole process is integrated in the pressing action, manual gluing is not needed, the uniformity and coating efficiency of the gluing are guaranteed, the adhesion strength and reliability of the core stator and the coil are improved, the gluing inconsistency and missing phenomenon caused by human factors are effectively reduced, thereby the consistency of the brushless motor assembly and the reliability of the product are further improved.

[0066] The airbag compression assembly 105 is connected to the cover base plate 31.

[0067] In addition, such as Figure 2 As shown, the positioning seat body 21 is also provided with an adhesive guide through hole 26 for connecting the guide slide 23 with the external space, and an adhesive guide groove 27 provided on the inner side wall of the cable guide through hole 24 for the airbag compression assembly 105 to be movably inserted.

[0068] The airbag assembly 104 includes an airbag body 1041 inserted into the adhesive guide groove 27 and located below the airbag compression assembly 105, an air inlet check valve 1042 connected to the airbag body 1041 and located in the direction close to the elastic reset mechanism 5, an air blowing conduit 1043 for connecting the airbag body 1041 and the adhesive storage assembly 103, and an air outlet check valve 1044 connected to the air blowing conduit 1043.

[0069] When the airbag extrusion assembly 105 moves downward along the adhesive guide groove 27 and applies extrusion force to the airbag body 1041, the airbag body 1041, under pressure, directs gas through the air outlet check valve 1044 into the adhesive storage assembly 103 along the air blowing conduit 1043, thereby ensuring that the adhesive is accurately and evenly pushed to the adhesive application area. When the airbag body 1041 returns to its original position, external air enters the airbag body 1041 through the air inlet check valve 1042. This application achieves the linkage between the automatic inflation and deflation of the airbag body 1041 and the quantitative delivery of adhesive, improving the automation, sealing and consistency of the adhesive application process, reducing human error, and ensuring the bonding effect of the iron core stator and the coil and the product assembly quality.

[0070] The airbag body 1041 is preferably an elastic reset airbag, which can automatically reset when the compression pressure is removed.

[0071] And, as Figure 2 As shown, the glue storage assembly 103 includes a storage tank 1031 connected to the air blowing conduit 1043, a guide pipe 1032 inserted at the bottom of the storage tank 1031 and connected to the annular glue application assembly 102, and a check valve 1033 located on the upper side of the storage tank 1031 and connected to the guide pipe 1032.

[0072] In the pressing and gluing process, when the airbag assembly 104 injects gas into the storage tank 1031 through the air blowing conduit 1043, the glue in the storage tank 1031 is pressurized and flows along the guide pipe 1032 to the annular gluing assembly 102, realizing the quantitative output of glue. The check valve 1033 is used to prevent glue backflow and ensure that glue only enters the guide pipe 1032 in one direction. This application improves the gluing efficiency and uniformity by driving the automatic and stable output of glue with air pressure, and effectively avoids the risk of glue leakage and backflow.

[0073] Further, as shown in Figure 2 The annular glue coating assembly 102 comprises an annular pipeline 1021 connected with the glue coating support 101, a soft glue guide nozzle 1022 in communication with the annular pipeline 1021 and extending in the direction facing the press-fitting guide mechanism 3, and a glue coating brush 1023 connected with the inner side wall of the annular pipeline 1021 and extending in the direction facing the press-fitting guide mechanism 3. The soft glue guide nozzle 1022 and the glue coating brush 1023 are arranged in an array along the circumferential side of the annular pipeline 1021.

[0074] The soft glue guide nozzle 1022 and the glue coating brush 1023 of the present application are inserted between the core stator and the motor base and located above the core stator. In the glue coating process, the glue in the glue storage assembly 103 is distributed to the plurality of soft glue guide nozzles 1022 through the annular pipeline 1021, realizing annular and multi-point synchronous glue spraying on the upper side of the core stator. After the press-fitting of the core stator and the motor base is completed, the core stator and the motor base are kept with a gap, the elastic reset mechanism 5 is reset and drives the press-fitting guide mechanism 3 to move upward, the press-fitting guide mechanism 3 drives the press-fitted core stator and motor base to move upward synchronously, and the glue coating brushes 1023 distributed on the inner circumferential side of the annular pipeline 1021 will in turn tightly contact the upper side wall and the circumferential side wall of the core stator, cooperating with the sprayed glue to perform secondary uniform coating and spreading, effectively improving the uniformity and coverage of glue distribution, avoiding the problems of missed coating and local over-thickness. The present application improves the bonding reliability and consistency of the core stator and the coil, and improves the overall quality and production efficiency of the press-fitting.

[0075] Further, as shown in Figure 2 and Figure 3 The positioning seat 2 further comprises a core glue coating groove 28 located below the annular glue coating assembly 102 and sleeved on the circumferential side of the positioning support protruding edge 22, which is used for inserting the bottom of the core stator.

[0076] The core glue coating groove 28 of the present application is used for receiving the overflowed glue during the spraying of the soft glue guide nozzle 1022. The core stator is inserted into the core glue coating groove 28, so that the bottom of the core stator is coated with glue. The setting of the core glue coating groove 28 not only prevents the glue from flowing out, but also coats the bottom of the core stator, further improving the reliability of the glue coating operation and the utilization rate of the glue, and effectively improving the overall assembly precision and product consistency of the press-fitting device.
