DETAILED DESCRIPTION

[0037] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below in combination with the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0038] In the assembling process of the motor, the fan cover needs to be assembled on the motor main body. The radial dimension of the fan cover is usually larger than that of the motor main body, and during the installation process, the inner circumferential surface of the fan cover needs to be glued, and then the fan cover is covered on the outer circumference of the motor main body. After the glue dries, the glue can connect the fan cover and the motor main body. By using this kind of assembling method, the consumption of glue is large, which is not conducive to reducing the production cost.

[0039] Please refer to Figure 1, based on the above problems, the embodiment of the application provides an assembling device 100, which is used for assembling a motor 4 and can perform aging test on the motor 4. The assembling device 100 comprises a supporting mechanism 1, a positioning mechanism 2 and a press-fitting mechanism 3. The positioning mechanism 2 is used for arranging a motor body 41, and the press-fitting mechanism 3 is used for arranging a fan cover 42 and driving the fan cover 42 to press fit the motor body 41.

[0040] It should be noted that in the embodiment of the application, the first direction is the Z-Z direction, and the second direction is any direction intersecting the first direction, and the embodiment of the application does not limit the specific direction of the second direction.

[0041] Please refer to Figure 1 In some embodiments, the positioning mechanism 2 comprises a supporting body 21 connected to the supporting mechanism 1, and the supporting body 21 is used for supporting the motor body 41 along the first direction, and the first direction is the height direction of the supporting body 21. The press-fitting mechanism 3 comprises a driving assembly 31 connected to the supporting mechanism 1, and the driving assembly 31 is used for driving the fan cover 42, and the driving assembly 31 is used for driving the fan cover 42 to press fit the motor body 41 along the first direction, so that the fan cover 42 and the motor body 41 are in interference fit. By using the press-fitting mechanism 3 to press fit the fan cover 42, the fan cover 42 and the motor body 41 are in interference fit, a circumferential pre-tightening force is generated, the inner circumferential surface of the fan cover 42 is tightly attached to the outer circumferential surface of the motor body 41 without any space, and the fan cover 42 and the motor body 41 are tightly and rigidly connected. While ensuring the connection strength of the fan cover 42 and the motor body 41, the use of glue can be omitted, the step of dispensing glue and the consumables can be omitted, the assembly process is simplified, and the production cost is reduced.

[0042] Further, the interference fit between the fan cover 42 and the motor body 41 can realize the circumferential sealing of the fan cover 42 and the motor body 41, can avoid the leakage of circumferential airflow when the motor 4 is running at high speed, and can ensure the wind guiding efficiency of the fan cover 42. At the same time, the interference fit between the fan cover 42 and the motor body 41 can block the foreign matter from entering the inside of the motor 4. At the same time, the interference fit between the fan cover 42 and the motor body 41 realizes the tight connection, even if the motor 4 runs at high speed and generates radial vibration, the fan cover 42 will not rotate or deviate relative to the motor body 41, and the problems such as wear caused by circumferential looseness can be avoided, and the durability of the motor 4 is improved. In addition, the interference fit between the fan cover 42 and the motor body 41 can improve the circumferential concentricity between the fan cover 42 and the motor body 41, and when the motor 4 runs at high speed, the fan cover 42 and the motor body 41 will not cause eccentric vibration, and the noise of the motor 4 can be reduced.

[0043] It needs to be explained that the radial dimension of the fan cover 42 and the radial dimension of the motor body 41 are similar in the present application, in order to ensure that the fan cover 42 can be better interference fitted with the motor body 41. On the one hand, it is necessary to provide sufficient external force for press fitting, and on the other hand, it is necessary to ensure that the positioning accuracy between the two is high, so as to prevent the two from being misaligned or deviated during press fitting.

[0044] Please refer to Figure 2 and Figure 3 It needs to be explained that the motor 4 of the present application comprises a motor body 41 and a fan cover 42. The motor body 41 comprises a circuit board 411, a conductive terminal 412, an upper shell 413 and a lower shell 414, please refer to Figure 3 The upper shell 413 has a first abutting edge 4131, and the fan cover 42 is interference fitted and press fitted on the first abutting edge 4131. Please refer to Figure 2 The upper shell 413 also has a second abutting edge 4132. The circuit board 411 is located in the inner periphery of the lower shell 414, and the lower shell 414 protrudes in the first direction relative to the circuit board 411 to form a protrusion 4141.

[0045] Please refer to Figure 4 First, the specific structure of the positioning mechanism 2 in the present application is introduced:

[0046] Please refer to Figure 5 In some embodiments, the positioning mechanism 2 further comprises a profiling positioning piece 22, which is arranged on the support body 21 and is used to limit the motor body 41 in the second direction. The second direction intersects the first direction. The setting of the profiling positioning piece 22 can reduce the deviation of the motor body 41 during the press fitting stress, thereby ensuring the positioning accuracy of the press fitting.

[0047] In optional embodiments, the profiling positioning piece 22 can be arranged inside the support body 21 or outside the support body 21. The present application does not limit the setting position of the profiling positioning piece 22 on the support body 21.

[0048] Please refer to Figure 5 In optional embodiments, the number of profiling positioning pieces 22 can be one or more. When the number of profiling positioning pieces 22 is more than one, all the profiling positioning pieces 22 are arranged in intervals and surround the motor body 41, which can limit the motor body 41 from all directions of the outer periphery surface of the motor body 41.

[0049] Please refer to Figure 4 In optional embodiments, the support body 21 comprises a first support plate 212 and two second support plates 213, which are arranged at the bottom of the first support plate 212 and opposite to each other, and the second support plate 213 is used to support the first support plate 212.

[0050] Referring to Figure 5 , the first support plate 212 is provided with a mounting through hole 214 penetrating in the first direction, and all the profiled positioning members 22 are arranged at intervals along the hole wall of the mounting through hole 214. The motor body 41 is arranged in the mounting through hole 214 and is limited by the plurality of profiled positioning members 22.

[0051] In an optional embodiment, the profiled positioning member 22 is made of plastic. The profiled positioning member 22 made of plastic can reduce the scratching of the motor body 41 during the limiting process, thereby reducing the damage of the motor body 41.

[0052] During the press-fitting process, the radial dimensions of the fan cover 42 and the motor body 41 are similar, and an external force needs to be applied to realize the extrusion deformation, so as to achieve the interference fit connection. If the external force is directly applied, the motor body 41 may be damaged. Therefore, before pressing down, the bottom surface of the motor body 41 needs to be supported, that is, the second abutting edge 4132 of the upper shell 413 of the motor body 41 needs to be supported. Figure 2

[0053] Referring to Figure 4 , in some embodiments, the positioning mechanism 2 further comprises a supporting assembly 23 arranged on the support body 21, and the supporting assembly 23 is used for limiting the motor body 41 in the first direction and / or the second direction intersecting with the first direction. Referring to Figure 4 The supporting assembly 23 can limit the bottom surface of the motor body 41 in the first direction, or the supporting assembly 23 can also limit the outer periphery of the motor body 41 in the second direction. The supporting assembly 23 can support and limit the motor body 41 during the press-fitting process, thereby improving the supporting effect of the motor body 41 and avoiding damage and breakage of the motor body 41.

[0054] In an optional embodiment, the supporting assembly 23 supporting the bottom surface of the motor body 41 can be power-driven support or non-power-driven support. The non-power-driven support means that the supporting assembly 23 is directly arranged on the bottom of the motor body 41 in the first direction, and does not need to be moved to the bottom of the motor body 41 in the first direction by power driving.

[0055] Referring to Figure 4 ​In some embodiments, the supporting assembly 23 comprises a first driver 231 connected to the supporting body 21 and a supporting component 232 connected to the first driver 231, the first driver 231 drives the supporting component 232 to move in a second direction, the second direction intersects the first direction. It can be understood that when the first driver 231 drives the supporting component 232 to move in the second direction, the supporting component 232 can move to limit the motor body 41, so that the motor body 41 is overlapped on the supporting component 232. When the first driver 231 drives the supporting component 232 to retract, i.e., drives the supporting component 232 to move in the second direction to move away from the motor body 41, it is convenient to disassemble and assemble the motor body 41, and the interference of disassembling and assembling the motor body 41 is reduced.

[0056] Please refer to Figure 4 In optional embodiments, the first driver 231 and the supporting component 232 comprise two groups, each group of the first driver 231 and the supporting component 232 is arranged on both sides of the motor body 41 in the second direction. Each first driver 231 drives the corresponding supporting component 232 to move in the second direction to approach the motor body 41, so that the two supporting components 232 limit the motor body 41. Or each first driver 231 drives the corresponding supporting component 232 to retract in the second direction.

[0057] In optional embodiments, the first driver 231 can be a driving motor or a driving cylinder.

[0058] Please refer to Figure 4 In some embodiments, the positioning mechanism 2 further comprises a stopper 24 arranged on the supporting body 21, the stopper 24 is located on one side of the supporting component 232 in the second direction, and the stopper 24 is used to stop the supporting component 232. The arrangement of the stopper 24 can prevent the supporting component 232 from overextending and affecting the motor body 41.

[0059] Please refer to Figure 4 In optional embodiments, the number of stoppers 24 is multiple, and each supporting component 232 can be correspondingly provided with one or more stoppers 24. The arrangement of multiple stoppers 24 corresponding to each supporting component 232 can improve the stopping effect.

[0060] In optional embodiments, the first driver 231 drives the supporting component 232 to extend into the bottom of the motor body 41 in the first direction, so that the supporting component 232 is just supported on the bottom surface of the motor body 41, i.e., the supporting component 232 is just supported on the second abutting edge 4132 of the upper shell 413 of the motor body 41.

[0061] Please refer to Figure 6In other optional embodiments, a gap d can be reserved between the supporting assembly 23 and the second abutting edge 4132 of the bottom surface of the motor body 41 along the first direction. In this way, the bottom of the motor body 41 has enough space to set the supporting assembly 23, which can provide enough space for the movement of the supporting assembly 23, and reduce the possibility of the motor body 41 being pushed over or pushed aside during the movement of the first driver 231 driving the supporting component 232 along the first direction.

[0062] Please refer to Figure 6 Further, since the gap d is reserved between the supporting assembly 23 and the second abutting edge 4132 of the bottom surface of the motor body 41 along the first direction, the height of the motor body 41 along the first direction needs to be adjusted so as to be able to fall on the top surface of the supporting assembly 23. Please refer to Figure 6 In some embodiments, the positioning mechanism 2 further comprises a moving assembly 25 connected to the supporting mechanism 1, and the moving assembly 25 is used to drive the motor body 41 to move along the first direction, so that the second abutting edge 4132 of the bottom surface of the motor body 41 abuts on the supporting assembly 23. The addition of the moving assembly 25 can drive the motor body 41 to move along the first direction, and then lower the motor body 41 to fall on the bottom of the supporting assembly 23. In this way, by means of the reserved gap d, the smooth movement of the supporting assembly 23 to the bottom of the motor body 41 can be ensured, and the motor body 41 will not be pushed aside or pushed over. At the same time, the moving assembly 25 is arranged to drive the motor body 41 to lower the height of the gap d, and then to be lapped on the top surface of the supporting assembly 23.

[0063] Please refer to Figure 4 and Figure 6 In some embodiments, the moving assembly 25 comprises a second driver 251 and a moving component 252, the second driver 251 is connected to the supporting mechanism 1, the second driver 251 drives the moving component 252, the moving component 252 is used to be connected to the motor body 41 along the first direction, and the moving component 252 is movably connected to the supporting body 21 along the first direction, and the second driver 251 is used to drive the moving component 252 to move along the first direction, so that the moving component 252 drives the motor body 41 to move along the first direction, and the bottom surface of the motor body 41 abuts on the supporting assembly 23. The addition of the moving component 252 driving the motor body 41 can improve the connection stability.

[0064] Please refer to Figure 7In some embodiments, the moving component 252 comprises a support 2521, a guide 2522 and an elastic member 2523. The support 2521 is connected to the motor body 41 and drivingly connected to the second driver 251. The support 2521 is provided with a first mounting hole 2521a in the first direction. One end of the guide 2522 is connected to the support body 21, and the other end is movably provided in the first mounting hole 2521a. The elastic member 2523 is sleeved on the outer periphery of the guide 2522, and the two ends of the elastic member 2523 in the first direction abut against the bottom surface of the support 2521 and the guide 2522, respectively. Since the other end of the guide 2522 is movably provided in the first mounting hole 2521a, the support 2521 can move along the guide 2522 through the first mounting hole 2521a. The second driver 251 is drivingly connected to the support 2521, so that the support 2521 descends along the guide 2522 in the first direction, and the motor body 41 is driven by the support 2521 to descend in the first direction by a distance d, so that the motor body 41 can be overlapped on the top surface of the supporting assembly 23. The moving component 252 is provided with the guide 2522 and the elastic member 2523, which can buffer the descent of the support 2521, so that the bottom surface of the motor body 41 can gradually descend to contact the supporting assembly 23, and the hard collision between the motor body 41 and the supporting assembly 23 can be reduced to damage the motor body 41.

[0065] Referring to Figure 7 In optional embodiments, the support 2521 comprises a connecting portion 2521b and a plurality of floating portions 2521c connected to each other. The floating portions 2521c are spaced apart from each other on the outer periphery of the connecting portion 2521b. The connecting portion 2521b is connected to the motor body 41 and drivingly connected to the second driver 251. The guide 2522 and the elastic member 2523 comprise a plurality of guides 2522 and a plurality of elastic members 2523, respectively. Each floating portion 2521c is provided with a plurality of first mounting holes 2521a. Each guide 2522 is provided in a corresponding first mounting hole 2521a, and each elastic member 2523 is sleeved on a corresponding guide 2522. The plurality of floating portions 2521c, guides 2522 and elastic members 2523 can improve the buffering effect.

The driving assembly 31 drives the second guide 32 to move along the first direction with the fan cover 42, and abut against the first guide 26. The arrangement of the first guide 26 and the second guide 32 can improve the abutting precision of the fan cover 42 pressing the motor body 41, in other words, the abutting of the first guide 26 and the second guide 32 can assist the abutting of the fan cover 42 and the motor body 41.

[0067] In optional embodiments, the first guide 26 is provided with an abutting hole, and the second guide 32 is provided with an abutting column which is inserted into the abutting hole.

It can be understood that the second guide 32 abuts against the first guide 26 first, and then the fan cover 42 is pressed on the motor body 41. In this way, the abutting of the second guide 32 and the first guide 26 can realize the positioning of the relative position of the fan cover 42 and the motor body 41 in advance, and further improve the pressing precision.

[0086] Referring to Figure 9In optional embodiments, the clamping assembly 36 comprises a fifth driver 361 and a clamping piece 362.

[0087] Referring to Figure 9 In some embodiments, the press-fitting mechanism 3 further comprises a pressure sensor 33 connected to the driving assembly 31. The pressure sensor 33 is used to detect the pressure value of the fan cover 42 in the first direction. The pressure sensor 33 can control the pressure of the fan cover 42 press-fitting the motor body 41, thereby ensuring the press-fitting position of the fan cover 42 and the motor body 41. By setting a preset pressure value for the pressure sensor 33, the pressure of each press-fitting can be kept at the preset pressure value, which can avoid excessive or insufficient press-fitting pressure, ensure the uniformity of press-fitting, and improve the press-fitting quality.

[0088] Referring to Figure 9 In optional embodiments, the pressure sensor 33 is arranged between the output end of the fourth driver 311 and the mounting plate 312.

[0089] In optional embodiments, the pressure sensor 33 can be a piezoresistive pressure sensor, a capacitive pressure sensor, etc.

[0090] Referring to Figure 9 In some embodiments, the press-fitting mechanism 3 further comprises a displacement sensor 34 arranged on the supporting mechanism 1.

[0091] In optional embodiments, the displacement sensor 34 can be a laser displacement sensor, an ultrasonic sensor, a slot photoelectric sensor, etc.

[0092] Referring to Figure 9In some embodiments, the displacement sensor 34 comprises a plurality of slot photoelectric cells 341, all of which are spaced apart along the first direction on the support mechanism 1, and the pressing mechanism 3 further comprises a shielding member 342, which is configured to be connected to the wind cover 42, and the driving assembly 31 is configured to drive the wind cover 42 to drive the shielding member 342 to pass through the slot photoelectric cells 341 in sequence, so as to detect the displacement value of the wind cover 42 along the first direction. The slot photoelectric cell 341 can realize non-contact measurement, does not directly contact the wind cover 42, and can reduce the influence on the wind cover 42. In addition, the slot photoelectric cell 341 has high precision, short photoelectric signal conversion time, and fast response speed.

[0093] It can be understood that the slot photoelectric cell 341 is usually in a U-shaped or slot-shaped structure. The two sides of the slot of the slot photoelectric cell 341 are respectively provided with a photoelectric emitter and a photoelectric receiver, and a gap (slot width) is left in the middle for the shielding member 342 to pass through. The photoelectric emitter in the slot photoelectric cell 341 is usually an infrared light-emitting diode, which is responsible for emitting a constant or modulated light signal. The photoelectric receiver is usually a phototransistor or a photodiode, which is used to receive the light signal emitted by the emitter and convert it into an electrical signal.

All of the slot photoelectric cells 341 are mounted at fixed intervals along the guide rail 39. The physical position coordinates of each slot photoelectric cell 341 are known. When the shielding member 342 on the mounting plate 312 moves under the drive of the fifth driver 361, it passes through the slots of the slot photoelectric cells 341 in sequence, and the shielding of the light path causes the sensor state to switch from on to off. Each slot photoelectric cell 341 outputs an electrical signal to detect the displacement value of the shielding member 342, so as to control the displacement value of the wind cover 42.

[0096] Next, the specific structure of the support mechanism 1 will be introduced:

[0097] Please refer to Figure 4 The support mechanism 1 comprises a support bottom plate 11, a support top plate 12 and a support column 13, the support top plate 12 and the support bottom plate 11 are arranged at the top and bottom of the support column 13 along the first direction, the pressing mechanism 3 is arranged on the support top plate 12, and the positioning mechanism 2 is arranged on the support bottom plate 11.

[0100] The motor body 41 is placed in the mounting hole 214 of the support body 21, and the bottom of the motor body 41 is in contact with the connecting part 2521b of the support part 2521. The outer periphery of the motor body 41 is limited by the profiling positioning part 22 in the mounting hole 214. The first driver 231 is driven to drive the supporting part 232 to extend into the second abutting edge 4132 of the upper shell 413 of the motor body 41, and at this time, a gap d is reserved between the top surface of the supporting part 232 and the second abutting edge 4132. Then, the second driver 251 is driven to drive the support part 2521 to move downward along the guide part 2522, the support part 2521 compresses the elastic part 2523, and the support part 2521 drives the motor body 41 to move downward by a distance d, so that the second abutting edge 4132 of the upper shell 413 of the motor body 41 is overlapped on the supporting part 232, and the supporting part 232 provides a supporting force to the motor body 41. Then, the suction accessory 35 is connected to the external air source, and the wind cover 42 is sucked. The fourth driver 311 drives the mounting plate 312 to drive the suction accessory 35 to move the wind cover 42 downward, the pressure sensor 33 detects the pressure received by the wind cover 42, and the displacement sensor 34 detects the displacement of the wind cover 42. During the downward movement of the wind cover 42, the first guide part 37 is positioned in abutment with the second guide part 38, the first guide part 37 and the second guide part 38 guide the movement, and then the wind cover 42 is press-fitted on the upper shell 413 of the motor body 41 to realize interference fit assembly, thereby completing the assembly of the motor 4.

[0101] Please refer to ​ It should be noted that a sealing part 43 is arranged at the top of the inner cavity of the wind cover 42, and the sealing part 43 is usually sealing foam. During press-fitting, the sealing part 43 is in contact with the impeller of the motor body 41. The assembled motor 4 also needs to be subjected to aging test, which is used to simulate the friction between the impeller and the sealing part 43 during long-term operation, detect whether the sealing part 43 is caused to fail due to wear, such as air leakage or noise increase, and confirm whether the material of the sealing part 43 is aging-resistant. The third driver 271 drives the conductive clamping jaw 272 to clamp the conductive terminal 412 at the bottom of the motor body 41, and after the external power supply is connected, the motor body 41 is supplied with power, so that the impeller of the motor body 41 is operated at high speed and rubs against the sealing foam to perform wear aging test.

[0102] Since the assembly device 100 is arranged in the embodiment of the application, the consistency and yield of the press-fitting of the wind cover 42 and the motor body 41 can be improved, so that the test conditions of the aging test of the assembled motor 4 can also be improved, and the accuracy of the aging test is further improved.
