Description

Technical Field

[0001] The present application relates to the field of intelligent manufacturing technology, and in particular to an automatic fan assembly line. Background Art

[0002] Manual assembly of server cooling fan rotors remains a key method for some companies, particularly those involved in small- and medium-volume production and high-precision customization. This process is significantly affected by human factors, with varying worker habits leading to fluctuations in assembly accuracy. The long assembly cycle per workstation and the time-consuming assembly of individual rotors make it difficult to meet the demands of large-scale production. Furthermore, repetitive pressing and welding operations can lead to worker fatigue and errors. Furthermore, the lack of real-time data logging makes it difficult to trace quality issues and pinpoint specific links, resulting in low assembly efficiency. Summary of the Invention

[0003] The present application provides an automatic fan assembly line to at least solve the problem of low efficiency and poor precision in manual assembly of heat dissipation fans in the related art.

[0004] The present application provides a fan automatic assembly line for mounting a first bearing having a central shaft mounted thereon and a second bearing on a fan body, wherein the fan body has a first surface and a second surface opposite to each other. The fan automatic assembly line sequentially comprises:

[0005] a loading mechanism configured to load the fan body with the first surface facing upward;

[0006] a first assembly part configured to mount the first bearing on the fan body;

[0007] a flip mechanism configured to flip the fan body on which the first bearing is mounted, so that the fan body is transported with the second surface facing upward;

[0008] The second assembly part is configured to install the second bearing between the fan body and the central shaft.

[0009] Through this application, the feeding mechanism can feed the fan body with the first side facing upward. During assembly, the middle shaft and the first bearing can be assembled separately in advance, which can save the waiting time of the fan automatic assembly line. The first assembly part can be used to assemble the first bearing and the middle shaft as a whole on the fan body. Then, the flipping mechanism can be used to flip the fan body so that the fan body changes from the first side facing upward to the second side facing upward, so that the second bearing can be completely installed on the fan body using the second assembly part. Fully automatic assembly can be achieved from loading to unloading. By replacing manual labor with machines, the labor intensity of operators can be reduced. The machine operation is controllable, and the influence of human factors can be eliminated, errors can be reduced, assembly accuracy can be improved, and product quality can be ensured. In addition, the automated assembly line can work continuously, greatly improving production efficiency. It can also record assembly process parameters in real time, and parameters such as pressure, temperature, and angle in the assembly process can be digitized. Quality problems can be located at specific links without relying on human recollection. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] An embodiment of the present application provides a fan automatic assembly line for installing a first bearing with a central axis and a second bearing on a fan body. Specifically, the fan automatic assembly line of the present application can install the central axis on the first bearing, and then assemble the first bearing, the central axis and the second bearing as a whole on the fan body.

[0036] The fan body has a first surface and a second surface relative to each other. The first bearing is assembled on the side of the fan body where the first surface is located, and the second bearing is assembled on the side of the fan body where the second surface is located. The first bearing and the second bearing need to be assembled corresponding to the specific positions on the actual central axis and the fan body.

[0037] When implementing it, refer to Figures 1 to 7As shown, the fan automatic assembly line includes a first transmission mechanism (including a first guide rail 1 and a first drive mechanism 2), a loading mechanism 3, a third assembly part 4, a first assembly part 5, a second transmission mechanism (a second guide rail 6 and a second drive mechanism 7), a flipping mechanism 8, a second assembly part 9 and a unloading mechanism 10.

[0038] Among them, the loading mechanism 3 is configured to load the fan body with the first side facing upward, the first assembly part 5 is configured to install the first bearing on the fan body, the flipping mechanism 8 is configured to flip the fan body with the first bearing installed so that the fan body is transmitted with the second side facing upward, and the second assembly part 9 is configured to install the second bearing between the fan body and the central axis.

[0039] The loading mechanism 3 can load the fan body with the first side facing upward. During assembly, the central shaft and the first bearing are assembled separately in advance, which can save the waiting time of the fan automatic assembly line. The first assembly part 5 can be used to assemble the first bearing and the central shaft as a whole on the fan body, and then the flipping mechanism 8 can be used to flip the fan body so that the fan body changes from the first side facing upward to the second side facing upward, so that the second bearing can be completely installed on the fan body using the second assembly part 9.

[0040] That is, the fan automatic assembly line of the present application can achieve fully automatic assembly from loading to unloading. By replacing manual labor with machines, the labor intensity of operators can be reduced. The machine operation is controllable, which can eliminate the influence of human factors, reduce errors, improve assembly accuracy, and ensure product quality. Moreover, the automated assembly line can work continuously, greatly improving production efficiency. It can also record assembly process parameters in real time, and can digitize parameters such as pressure, temperature, and angle in the assembly process. Quality problems can be located at specific links without relying on human recollection.

[0041] In some embodiments, reference Figure 1 and Figure 2 As shown, the feeding mechanism 3 includes a feeding belt 301 and a feeding belt 302. The feeding belt 301 is used to arrange the fan body so that the fan body is neatly arranged on the feeding belt 301. The feeding belt 301 provides the fan body to the feeding belt 302 at a frequency of one at a time. The feeding belt 302 is used to realize the loading of the fan body.

[0042] Specifically, the feed belt 301 has a feed outlet, and the loading belt 302 has a loading inlet. A rotating guide wheel 303 is arranged between the feed outlet and the loading inlet. The rotating guide wheel 303 is provided with multiple slots 304 at intervals along the circumferential direction. The slots 304 are connected with the feed outlet so that the fan bodies arranged neatly on the feed belt 301 can enter the slots 304 at the feed outlet. The rotating guide wheel 303 can drive the fan bodies to rotate. When the direction of the slots 304 is consistent with the running direction of the loading belt 302, the fan bodies can be disengaged from the slots 304 at the loading inlet, so that the fan bodies can be transferred to the loading belt 302, and finally the fan bodies can be loaded through the loading belt 302.

[0043] In a specific implementation, the feed outlet only allows one fan body to pass through at the same time, so that the fan body can be prevented from being blocked at the notch of the slot 304 .

[0044] Specifically, the fan automatic assembly line of the present application also includes an assembly platform, the rotating guide wheel 303 is arranged on the assembly platform, and can rotate relative to the assembly platform, and the feeding belt 301 and the loading belt 302 are also arranged on the assembly platform. Such an arrangement can realize the movement of the fan body on the feeding belt 301, the rotating guide wheel 303 and the loading belt 302, thereby realizing the loading of the fan body.

[0045] Reference Figure 2 As shown, a guide mechanism 305 is provided on the feed belt 301. In the conveying direction of the feed belt 301, i.e., the direction of movement of the fan body, the guide mechanism 305 is arranged at an angle from the first side of the feed belt 301 to the second side, and a feed outlet is formed between the end of the guide mechanism 305 and the second side of the feed belt 301. In other words, the guide mechanism 305 guides and straightens the fan body, ensuring that the fan body always faces upward. In the forward direction of the feed belt 301, the width of the fan body is gradually reduced, so that the fan body gradually aligns neatly on the feed belt 301 and enters the slot 304 on the rotating guide wheel 303.

[0046] The guide mechanism 305 may be formed as a guide rod structure for guiding the movement of the fan body.

[0047] Specifically, there are multiple slots 304 , which are arranged in sequence along the circumferential direction of the rotating guide wheel 303 . The slots 304 are arranged with their openings facing away from the center of the rotating guide wheel 303 to facilitate entry of the fan body.

[0048] In some embodiments, a loading station 101 and a first installation station 102 are provided on the first guide rail 1. One end of the loading belt 302 is connected to the loading station 101 to transport the fan body to the loading station 101. The first drive mechanism 2 is used to transfer the fan body from the loading station 101 to the first installation station 102, so that the fan body can move on the first guide rail 1 to the first installation station 102 for installation of the first bearing. Only one fan body is placed on the loading station 101 at a time to avoid confusion in the transportation of the fan bodies.

[0049] The loading mechanism 3 is configured to place the fan body at the loading station 101 with the first surface facing upward, that is, the fan body is transported on the first transport mechanism with the first surface facing upward.

[0050] The second transmission mechanism includes a second guide rail 6 and a second driving mechanism 7. The second guide rail 6 is provided with a second installation station 601 and a unloading station 602. The flipping mechanism 8 transfers the fan body to the second guide rail 6. The second driving mechanism 7 drives the fan body from the second installation station 601 to the unloading station 602, so that the fan body can move on the second guide rail 6 to the unloading station 602 for unloading.

[0051] The flipping mechanism 8 is configured to flip the fan body, assembled with the central shaft, from the first conveying mechanism and transfer it to the second conveying mechanism, so that the fan body is transferred with the second surface facing upward. The second assembly unit 9 is configured to assemble the second bearing between the fan body and the central shaft at the second installation station 601. That is, the flipping mechanism 8 can transfer the fan body from the first conveying mechanism to the second conveying mechanism, and can flip the fan body assembled with the first bearing and central shaft transferred from the first conveying mechanism, so that the fan body can be installed with the second bearing at the second installation station 601. After the second bearing is assembled, the fan body can be transferred again to the downstream assembly line under the action of the second driving mechanism 7.

[0052] It should be noted that the first side of the fan body can be either the front or the back side, and correspondingly, the second side can be either the back or the front side. That is, the fan body can be transported on the first guide rail 1 with the front side facing upward or with the back side facing upward. This application does not impose any restrictions on this. As long as the flip mechanism 8 can be used to flip the fan body with the first side facing upward on the first guide rail 1 and the second side facing upward on the second guide rail 6, so that the first bearing and the second bearing can be assembled on the central shaft by pressing from top to bottom, it will be sufficient.

[0053] In some embodiments, the first driving mechanism 2 includes a first driving member 201, a first driving member 202 that drives the first driving member 201 to move along a first direction, and a second driving member 203 that drives the first driving member 201 to move along a second direction. The loading station 101 and the first installation station 102 are arranged along the first direction, and the second direction intersects with the first direction.

[0054] For example, the first direction is the X direction in the horizontal plane, the second direction is the vertical Z direction, the second driving member 203 drives the first toggle member 201 to move up and down in the vertical direction, and the first driving member 202 drives the first toggle member 201 and the second driving member 203 to move left and right in the horizontal plane. Specifically, the first toggle member 201 is initially in contact with the fan body. When the fan body needs to be moved, the first driving member 202 is directly used to drive it forward. Then, the second driving member 203 is used to drive the first toggle member 201 upward to avoid the fan body, and the first driving member 202 drives the first toggle member 201 backward. Then, the second driving member 203 drives the first toggle member 201 downward. At this time, the first toggle member 201 can return to its initial state, so as to repeatedly toggle the fan body forward.

[0055] Of course, the second direction can also be the Y direction in the horizontal plane, the second driving member 203 drives the first toggle member 201 to move forward and backward in the horizontal plane, the first driving member 202 drives the first toggle member 201 to move left and right in the horizontal plane, or the first direction and the second direction are any other two intersecting directions. This application does not limit this and can be arranged according to the actual scenario.

[0056] It should be noted that the first and second drive members 202, 203 are formed as cylinder structures, and their automatic press-fitting pressure is controllable, which can prevent axial displacement deviation of the magnetic steel and ensure uniform assembly stress. In specific implementation, the first actuator 201 is disposed on the cylinder moving end of the second drive member 203, and the second drive member 203 is disposed on the cylinder moving end of the first drive member 202.

[0057] The first actuator 201 is provided with a plurality of first claws 204 for moving the fan body in a first direction. Specifically, the first claws 204 are formed with a limiting groove on one side of the fan body to limit the fan body and ensure the fan body's movement path.

[0058] In a specific implementation, a first buffer station is further provided on the first guide rail 1 to buffer excess fan bodies. The first buffer station can be provided between the loading station 101 and the first installation station 102, or downstream of the first installation station 102, and can be specifically provided according to actual needs.

[0059] Specifically, the number of the first shifting claws 204 is the same as the number of the workstations on the first guide rail 1 , so as to shift the fan bodies on all the workstations to move simultaneously.

[0060] In some embodiments, the fan automatic assembly line further includes a first glue dispensing device 11 , which is located upstream of the first assembly component 5 to reduce the difficulty of assembling the downstream first assembly component 5 .

[0061] The first guide rail 1 is also provided with a first glue dispensing station 103, which is located between the loading station 101 and the first installation station 102. The first glue dispensing device 11 is used to perform glue dispensing on the first surface of the fan body at the first glue dispensing station 103. That is, when the fan body moves to the first glue dispensing station 103, glue is first applied by the first glue dispensing device 11. After the central shaft and the first bearing are assembled, the central shaft and the first bearing are installed on the fan body at the first installation station 102.

[0062] In some embodiments, reference Figure 3 As shown, the first dispensing device 11 includes a dispensing table 111 and a first rotating cylinder 112. A first claw 113 is provided on the first rotating cylinder 112. The first claw 113 is used to grab the fan body. The first rotating cylinder 112 drives the first claw 113 to rotate, and the first claw 113 has at least a first position corresponding to the first dispensing station 103 and a second position corresponding to the dispensing table 111.

[0063] It can be understood that when the fan body is moved to the first glue dispensing station 103, the first clamping claw 113 can move the un-glueized fan body to the glue dispensing table 111. At the same time, the fan body that has been glued on the glue dispensing table 111 can also be moved to the first glue dispensing station 103, so that the fan body that has been glued can be transferred to the first installation station 102 on the first guide rail 1.

[0064] Specifically, the glue dispensing gun is directly arranged corresponding to the glue dispensing station 111 so as to perform glue dispensing operation directly at the glue dispensing station 111 . After glue dispensing is completed, the fan body is moved to the second glue dispensing station 603 using the first clamping claw 113 .

[0065] It should be noted that one or more first dispensing devices 11 may be provided, and this application does not impose any limitation thereto, as long as it can ensure that all fan bodies on the first guide rail 1 can participate in the dispensing operation.

[0066] In some embodiments, the flipping mechanism 8 includes a second claw 801, a third driving member 802 that drives the second claw 801 to rotate about a third direction, and a fourth driving member that drives the second claw 801 to move in a fourth direction. The second claw 801 is used to grasp the fan body so as to flip the fan body via the third driving member 802. Specifically, when the first guide rail 1 and the second guide rail 6 are coaxially arranged, the fan assembly can be transferred between different transmission mechanisms using only a single movable cylinder. When the first guide rail 1 and the second guide rail 6 are not coaxial, multiple driving structures in different directions can be provided to cooperate and achieve the transfer of the fan assembly between different transmission mechanisms.

[0067] For example, the third driving member 802 can be used to realize the rotation of the second claw 801, and the fourth driving member includes a flip-transfer cylinder 803 and a flip-lifting cylinder 804. The flip-transfer cylinder 803 can realize position transfer in the horizontal plane, and the flip-lifting cylinder 804 can realize position transfer in the vertical direction. With such an arrangement, when the second claw 801 grasps the fan body, it can realize the transfer and flipping of the fan body in multiple cycles.

[0068] Of course, the third direction and the fourth direction can also be any other two intersecting directions. This application does not limit this and can be arranged according to actual scenarios.

[0069] In some embodiments, reference Figure 5 and Figure 6 As shown, the second assembly part 9 includes a first assembly table, a first bearing loading cylinder 901, a first pressing cylinder 902 and a third clamping claw. The first bearing loading cylinder 901 is used to provide the second bearing to the first assembly table. The first pressing cylinder 902 is arranged above the first assembly table to press the second bearing. The third clamping claw is used to grab the fan body and provide it to the first assembly table, as well as to grab the fan body with the second bearing installed from the first assembly table.

[0070] That is, the first bearing, the central axis and the fan body moved to the second installation station 601 can be grasped by the third claw to move to the first assembly table, and are arranged corresponding to the second bearing. Under the action of the first pressing cylinder, the second bearing can be assembled between the central axis and the fan body. After the assembly is completed, the third claw can be used again to return to the second installation station 601 to transfer the assembled finished product to the downstream assembly line through the second transmission mechanism.

[0071] In some embodiments, reference Figure 4As shown, the third assembly part 4 is used to assemble the middle shaft and the first bearing. The third assembly part 4 is located upstream of the first assembly part 5, and includes a second assembly table 401, a bearing placement table 402, a middle shaft placement table 403, a second bearing loading cylinder 404, a bearing picking cylinder 405, a middle shaft loading cylinder 406 and a middle shaft picking cylinder 407.

[0072] The first bearing is loaded onto the bearing placement table 402 through the second bearing loading cylinder 404, that is, the second bearing loading cylinder 404 can push out a first bearing from the bearing loading clip (the clip has an opening at the bottom), and the taken-out first bearing can be pushed onto the second assembly table 401 through the bearing picking cylinder 405. The middle shaft is loaded onto the middle shaft placement table 403 through the middle shaft loading cylinder 406, and is pushed onto the second assembly table 401 through the middle shaft picking cylinder 407.

[0073] Specifically, the method for the central axis taking cylinder 407 to grab the central axis can be a magnetic suction method. Of course, the method for the central axis taking cylinder 407 to grab the central axis can also be to grab it through a claw structure, and this application is not limited to this.

[0074] By designing a fixed stroke for the bearing picking cylinder 405 and the central shaft picking cylinder 407, the loading position between the first bearing to be assembled and the central shaft can be fixed each time, and the axes of the first bearing and the central shaft can be aligned, which can facilitate subsequent assembly operations.

[0075] That is, the extension direction of the bearing placement platform 402 is consistent with the extension or retraction direction of the bearing picking cylinder 405. After the second bearing loading cylinder 404 pushes a first bearing from the loading clip to the bearing placement platform 402, by designing the fixed stroke of the bearing picking cylinder 405, the first bearing can be moved to a fixed position, that is, the position of the second assembly platform 401; at the same time, the middle shaft picking cylinder 407 can grab the middle shaft to the position where the first bearing is located, that is, also at the position of the second assembly platform 401.

[0076] Continue to refer to Figure 4 As shown, a second pressing cylinder 408 is provided above the second assembly platform 401 to press the first bearing onto the central shaft via the second pressing cylinder 408. In a specific implementation, the stroke of the second pressing cylinder 408 is fixed to ensure the installation position of the first bearing on the central shaft and avoid over-assembly.

[0077] In practice, the third assembly unit 4 also includes a second rotary cylinder 409. The center shaft placement platform 403 is positioned at the output end of the second rotary cylinder 409 to adjust the center shaft from a horizontally fed material to a vertically distributed material. It will be appreciated that the center shaft is typically fed horizontally. The second rotary cylinder 409 allows the center shaft to be adjusted to the desired orientation for press-fitting the first bearing, facilitating installation of the first bearing.

[0078] Exemplarily, the middle shaft placement platform 403 is a sleeve-shaped structure. Under the action of the middle shaft loading cylinder 406, the middle shaft is loaded into the sleeve of the sleeve-shaped structure. When the second rotating cylinder 409 drives the middle shaft placement platform 403 to rotate, the middle shaft can be adjusted to be distributed in the vertical direction, so that the axis of the middle shaft is aligned with the axis of the first bearing for press-fit assembly.

[0079] It is understood that the third assembly unit 4 is configured to assemble the first bearing onto the central shaft, and the first assembly unit 5 is configured to assemble the central shaft, equipped with the first bearing, onto the fan body at the first installation station 102. In a specific implementation, the third assembly unit 4 is first used to complete the assembly of the first bearing and the central shaft. At this point, the fan body is moved from the loading station 101 to the first installation station 102. The first assembly unit 5 is then used to integrally assemble the first bearing and the central shaft onto the fan body at the first installation station 102. In this manner, the fan body, equipped with the central shaft and the first bearing, can be transferred to the downstream assembly line via the first transmission mechanism.

[0080] In some embodiments, reference Figure 3 As shown, a first guide groove is formed on the first guide rail 1, and the fan body is slidably arranged in the first guide groove, which can ensure the straightness of the fan body following the movement of the first guide rail 1. The shape of the first guide groove is adapted to the shape of the fan body.

[0081] Reference Figure 5 As shown, a second guide groove is formed on the second guide rail 6, and the fan body is slidably arranged in the second guide groove, which can ensure the straightness of the fan body following the movement of the second guide rail 6. The shape of the second guide groove is adapted to the shape of the fan body.

[0082] In some embodiments, the second driving mechanism 7 includes a second toggle member 701, a fifth driving member 702 that drives the second toggle member 701 to move along the fifth direction, and a sixth driving member 703 that drives the second toggle member 701 to move along the sixth direction. The second installation station 601 and the unloading station 602 are arranged along the fifth direction, and the sixth direction intersects with the fifth direction.

[0083] For example, the fifth direction is the X direction in the horizontal plane, and the sixth direction is the vertical Z direction. The sixth driving member 703 drives the second toggle member 701 to move up and down in the vertical direction, and the fifth driving member 702 drives the second toggle member 701 to move left and right in the horizontal plane. Specifically, the second toggle member 701 is initially in contact with the fan body. When the fan body needs to be moved, the fifth driving member 702 is directly used to drive it forward. Then, the sixth driving member 703 is used to drive the second toggle member 701 upward to avoid the fan body, and the fifth driving member 702 drives the second toggle member 701 backward. Then, the sixth driving member 703 drives the second toggle member 701 downward. At this time, the second toggle member 701 can return to its initial state, so as to repeatedly toggle the fan body forward.

[0084] Of course, the fifth direction can also be the Y direction in the horizontal plane, the sixth driving member 703 drives the second toggle member 701 to move forward and backward in the horizontal plane, the fifth driving member 702 drives the second toggle member 701 to move left and right in the horizontal plane, or the fifth direction and the sixth direction are any other two intersecting directions. This application does not limit this and can be arranged according to the actual scenario.

[0085] It should be noted that the fifth and sixth drive members 702 and 703 are cylinder structures, and their automatic press-fit pressure is controllable, which can prevent axial displacement deviation of the magnetic steel and ensure uniform assembly stress. In specific implementation, the second actuator 701 is disposed on the cylinder moving end of the sixth drive member 703, and the sixth drive member 703 is disposed on the cylinder moving end of the fifth drive member 702.

[0086] The second actuator 701 is provided with a plurality of second claws 704 for moving the fan body in the fifth direction. Specifically, the second claws 704 are formed with a limiting groove on one side of the fan body to limit the fan body and ensure the fan body's movement path.

[0087] Specifically, the number of the second shifting claws 704 is the same as the number of the workstations on the second guide rail 6 , so as to shift the fan bodies on all the workstations to move simultaneously.

[0088] In a specific implementation, a second buffer station is further provided on the second guide rail 6 to buffer excess fan bodies. The second buffer station can be provided between the second installation station 601 and the blanking station 602, or upstream of the second installation station 601, and can be specifically provided according to actual needs.

[0089] In some embodiments, the fan automatic assembly line further includes a second dispensing device 12 for adding dispensing agent to the fan body. The second dispensing device 12 is located upstream of the second assembly part 9 to reduce the assembly difficulty of the downstream second assembly part 9.

[0090] A second glue dispensing station 603 is also provided on the second guide rail 6, and the second glue dispensing station 603 is located before the second installation station 601. That is, when the fan body moves to the second glue dispensing station 603, glue is first dispensed by the second glue dispensing device 12, and then the second bearing is installed on the fan body at the second installation station 601.

[0091] Specifically, the dispensing gun is directly set corresponding to the second dispensing station 603, so that the dispensing operation can be performed directly at the second dispensing station 603. By setting the dispensing gun, the dispensing amount can be uniform, which can avoid the discreteness of the code disk bonding strength.

[0092] It should be noted that one or more second dispensing devices 12 can be provided, and this application does not impose any limitation on this, as long as it can ensure that all fan bodies on the second guide rail 6 can participate in the dispensing operation.

[0093] In some embodiments, the fan automatic assembly line also includes a curing device 13, which is located downstream of the second transmission mechanism and upstream of the unloading mechanism 10. The curing device 13 includes a curing track 131, a curing oven and a fourth clamp. The curing track 131 is passed through the curing oven to realize the glue curing of the fan body in the curing oven. The fan body on the second transmission mechanism is moved to the curing track 131 through the fourth clamp.

[0094] That is, after the fan body on the second transmission mechanism completes the assembly of the first bearing, the second bearing and the central axis, it can be moved to the curing track 131 using the fourth claw and enter the curing furnace to realize glue curing. After the glue curing is completed, the fan body can be unloaded through the unloading mechanism 10.

[0095] The unloading mechanism 10 is configured to unload the fan body, specifically after the first bearing, second bearing, and center shaft are assembled into the fan body. Specifically, the unloading mechanism 10 can be a unloading track, which interfaces with the curing track 131 to directly unload the fan body. Of course, the finished fan body can also be unloaded by gripping it with a claw structure, though this application does not limit this.

[0096] It should be noted that the third driving member 802 and the fourth driving member are both formed into a cylinder structure, and their automatic press-fitting pressure is controllable, which can avoid axial displacement deviation of the magnetic steel and make the assembly stress uniform.

[0097] The above is a detailed introduction to the fan automatic assembly line provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only intended to help understand the method and core concept of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
