[0031] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0032] Please see Figures 1 to 3 The cooling fan assembly machine 100 of the present invention includes a machine base 10a, a turntable 10b mounted on the machine base 10a, a support plate 20a spaced apart and located directly above the turntable 10a, and each of the support plates 20a mounted along the rotation direction of the turntable 10b (see...). Figures 1 to 3 The following components are arranged in a counter-clockwise direction: a stator pressing mechanism 20b, a gasket mounting mechanism 30, a buckle mounting mechanism 40a, a bearing mounting mechanism 40b, a bearing pressing mechanism 40c, an oiling mechanism 50a, a fan blade mounting mechanism 50b, a fan blade pressing mechanism 50c, a top cover mounting mechanism 60a, and a finished product unloading robot 70a.

[0033] The turntable 10b is provided with a plurality of tooling seats 11 arranged at intervals along the rotation direction of the turntable 10b and positioned by the bottom shell 210. Optionally, as an example, all the tooling seats 11 are arranged on the turntable 10b with equal central angles to ensure that the rotation angle of the turntable 10b in each step is consistent with the central angle, thereby achieving the purpose of the turntable 10b gradually conveying each tooling seat 11.

[0034] Next to the gasket loading mechanism 30, there is a gasket 230 located outside the turntable 10b (see... Figure 13 The vibratory disc mechanism 30a for vibration screening is mounted on the machine base 10a to continuously supply shims 230 to the shim loading mechanism 30. Next to the bearing loading mechanism 40b, there is a bearing screening disc 40d and a bearing 250 (see [reference]) for screening the bearings 250 after screening by the bearing screening disc 40d. Figure 13 The bearing 250 is transferred to the bearing transfer mechanism 40e directly below the bearing loading mechanism 40b. The bearing screening disc 40d is mounted on the machine base 10a and located outside the turntable 10b. Through the coordinated operation of the bearing transfer mechanism 40e and the bearing screening disc 40d, the bearing 250 is continuously fed to the bearing loading mechanism 40b. Alternatively, the bearing 250 can be transferred to the bearing loading mechanism 40b. Figure 2 and Figure 3 In this example, the bearing transfer mechanism 40e is mounted on the support plate 20a so that the bearing transfer mechanism 40e is arranged above the bearing screening disk 40d, thereby making the layout of the bearing transfer mechanism 40e between the bearing screening disk 40d and the bearing mounting mechanism 40b more compact.

[0035] Next to the oiling mechanism 50a, an oil supply container 50d is located outside the turntable 10b, and the oil supply container 50d provides sufficient oil to the oiling mechanism 50a; alternatively, at... Figure 1 In this example, the oil supply container 50d is mounted on the support plate 20a, which provides support for the oil supply container 50d and creates a height difference between the oil supply container 50d and the oil dispensing mechanism 50a, thus facilitating the delivery of oil from the oil supply container 50d to the oil dispensing mechanism 50a. Obviously, depending on actual needs, the oil supply container 50d can also be mounted on the machine base 10a; therefore, it is not considered... Figure 1 The above is the limit.

[0036] Next to the fan blade mounting mechanism 50b, there is a fan blade conveyor line 50e mounted on the machine base 10a and located outside the turntable 20a, so as to realize the external fan blade 260 (see Figure 13 The blades are continuously conveyed to the blade mounting mechanism 50b via the blade conveyor line 50e; alternatively, as an example, the blade conveyor line 50e may be, but is not limited to, a belt conveyor line and is arranged in a horizontally extended manner.

[0037] Next to the top cover mounting mechanism 60a, there is a top cover conveyor line 60b mounted on the machine base 10a and located outside the turntable 20a, so as to realize the external top cover 270 (see Figure 13 The cover is continuously conveyed to the cover mounting mechanism 60a via the cover conveyor line 60b; alternatively, as an example, the cover conveyor line 60b may be, but is not limited to, a belt conveyor line, and may be arranged horizontally. Specifically, in Figure 1 and Figure 2 As an example, a finished product unloading robot 70a is provided next to a finished product delivery line 70b, which is also located beside the machine 10a and below the finished product robot 70a, so that the finished product unloading robot 70a can transfer the finished cooling fan 200 taken from the tooling seat 11 of the turntable 20a from above to the finished product unloading robot 70a; alternatively, in Figure 1 In this example, the finished product delivery line 70b may be, but is not limited to, a belt conveyor line arranged horizontally; furthermore, since the finished product unloading robot 70a is already well known in the art, it will not be described in detail here. More specifically, see the description below.

[0038] like Figures 1 to 3 As shown, as an example, the cooling fan assembly machine 100 of the present invention further includes a gasket 230 (see [reference]) for being installed in the base housing 210 by the gasket mounting mechanism 30. Figure 13 The gasket testing mechanism 30b is used for testing the gasket, and the retaining ring 240 is used for testing the retaining ring 240 that is inserted into the bottom housing 210 by the retaining ring mechanism 40a (see...). Figure 13 The fastener inspection mechanism 40f performs the inspection. The fastener inspection mechanism 40f is located between the fastener mounting mechanism 40a and the bearing mounting mechanism 40b in the rotation direction of the turntable 10b. The gasket inspection mechanism 30b is located between the gasket mounting mechanism 30 and the fastener mounting mechanism 40a in the rotation direction of the turntable 10b. See the attached diagram for details. Figures 1 to 3 As shown, the purpose of this design is to ensure the pass rate and quality of the finished cooling fan 200 assembled by the cooling fan assembly machine 100 of the present invention. Specifically, the gasket detection mechanism 30b is used to detect whether a gasket is missing, and the retaining ring detection mechanism 40f is used to detect whether a retaining ring 240 is missing. It should be noted that since the gasket detection mechanism 30b, the retaining ring mechanism 40a, and the retaining ring detection mechanism 40f are well known in the art, they will not be described in detail here.

[0039] For example Figures 1 to 3As shown, as an example, the support plate 20a has a first exposed notch 21 and a second exposed notch 22 that protrude from the turntable 10b. The first exposed notch 21 is located between the stator pressing mechanism 20b and the fan blade pressing mechanism 50c; at this time, the finished product unloading robot 70a is partially located in the first exposed notch 21; this design facilitates the operator's operation of installing the bottom shell 210 into the tooling seat 11 at the first exposed notch 21. The second exposed notch 22 is located between the bearing pressing mechanism 40c and the fan blade pressing mechanism 50c, and the fan blade mounting mechanism 50b is partially located in the second exposed notch 22; this design allows the support plate 20a to provide an operating position for the operator through the second exposed notch 22. Furthermore, in... Figures 1 to 3 As an example, the support plate 20a is also provided with a first clearance notch 23 for the clearance of the shim mounting mechanism 30 and a second clearance notch 24 for the clearance of the buckle mounting mechanism 40a; the purpose of this design is to ensure that the shim mounting mechanism 30 mounts the shim 230 from above (see Figure 13 ) and the fastening mechanism 40a fastens the fastening ring 240 from above (see Figure 13 In this case, the connection between the pressure head and the bearing plate 20a is more compact. It should be noted that the pressure stator mechanism 20b and the pressure fan blade mechanism 50c are of the same type, both of which are driven by a motor through a lead screw and nut to move the pressure head in a loosening or pressing motion.

[0040] like Figure 4 and Figure 5 As shown, as an example, the gasket loading mechanism 30 includes a horizontal linear transfer module 31 mounted on the support plate 20a, a vertical linear transfer module 32 mounted on the horizontal linear transfer module 31, a lifting actuator 33 mounted on the vertical linear transfer module 32, a gasket mounting head 34 located correspondingly below the lifting actuator 33 and mounted on the vertical linear transfer module 32, and a centering rod 35 that can extend downward from the center of the gasket mounting head 34 or retract upward into the gasket mounting head 34; therefore, when gripping the gasket 230 (see... Figure 13 During the process, the gasket mounting head 34 first presses down on the gasket 230, and then the lifting drive 33 drives the centering rod 35 to pass through the center of the gasket 230, thereby centering the gasket 230 and improving the reliability of the gasket 230 installation. Specifically, in conjunction with Figure 6 and Figure 7As an example, the gasket mounting head 34 has an air passage 341 and a large shaft 342 and a small shaft 343 arranged coaxially from top to bottom; the inlet 3411 of the air passage 341 is located on the large shaft 342 to facilitate external air access by the operator; four partition grooves 3431 are provided on the end 343a of the small shaft 343 away from the large shaft 342, which are circumferentially spaced apart, dividing the end 343a into four conical blocks 3432; the outlet 3412 of the air passage 341 is located on the bottom surface 3433 of the partition groove 3431; the core rod 35 extends downward from the small shaft 343 or under the drive of the lifting drive 33. The gasket 230 is retracted upwards into the small shaft 343. This design reduces the contact area between the gasket mounting head 34 and the gasket 230, and facilitates the separation of the gasket mounting head 34 and the gasket 230 due to the reduced contact area. Furthermore, with the outlet 3412 of the air passage 341 located on the bottom surface 3433 of the partition groove 3431, and the core rod 35 extending downwards or retracting upwards into the small shaft 343 under the drive of the lifting drive 33, the airflow blown out from the outlet 3412 after the core rod 35 retracts upwards into the small shaft 343 further increases the ease of separation between the gasket mounting head 34 and the gasket 230, thereby effectively improving the reliability of the gasket 230 being assembled into the bottom shell 210. More specifically, in Figure 7 In this example, the end face 3434 of each conical block 3432 away from the bottom surface 3433 of the partition groove 3431 is a flat surface perpendicular to the axial direction of the small shaft 343. This ensures the reliability of the tight contact between the gasket 230 and each conical block 3432, and generates a certain degree of negative pressure adsorption force on the gasket 230 by means of this tight contact. This is because the gasket 230 in the finished cooling fan 200 is a silicone gasket. It should be noted that, although Figure 7 The diagram shows four dividing grooves 3431. Obviously, depending on actual needs, the number of dividing grooves 3431 can also be one, two, three, five, or more. Therefore, it is not limited to this. Figure 6 and Figure 7 The above is for reference only; in addition, the large shaft 342 and the small shaft 343 are named according to their diameters, with the larger diameter being called the large shaft 342 and the smaller diameter being called the small shaft 343.

[0041] like Figure 8 and Figure 9As shown, as an example, the bearing mounting mechanism 40b includes upper and lower frames 41 mounted on the support plate 20a, a rotary actuator 42 mounted on the upper and lower frames 41, a sliding frame 43 sliding upward and downward within the upper and lower frames 41, and a screw and nut transmission assembly 44 mounted between the sliding frame 43 and the rotary actuator 42. The sliding frame 43 also extends downward through the upper and lower frames 41 and is provided with a die head 45 and a pressure plate 46 located between the support plate 20a and the turntable 10b. A clearance space 461 is provided on the pressure plate 46, and upper and lower sliding rods 47 are mounted at opposite ends of the pressure plate 46. The upper and lower sliding rods 47 slide upward through the sliding frame 43, and are also fitted with springs 48 that elastically abut against the pressure plate 46 and the sliding frame 43. The die head 45 is located between the upper and lower sliding rods 47, and is also opposite the clearance space 461 in the vertical direction. Therefore, in the bearing mounting 250 (see... Figure 13 During operation, the rotary drive 42 drives the sliding frame 43, along with the die head 45, pressure plate 46, upper and lower sliding rods 47, and spring 48, to slide downwards via the lead screw and nut transmission assembly 44. Because the pressure plate 46 is biased downwards relative to the die head 45 under the action of the spring 48, during the downward sliding of the sliding frame 43, along with the die head 45, pressure plate 46, upper and lower sliding rods 47, and spring 48, the pressure plate 46 first presses against the bottom shell 210, and then the die head 45 grips the bearing 250 (see...). Figure 13 The spring 48 is installed inside the base shell 210, while the bearing 250 (see...) Figure 13 During the insertion into the bottom shell 210, the bearing 250 is pushed upwards and compressed by the pressure plate 46, thus storing energy. Therefore, the spring 48, pressure plate 46, and upper and lower sliding rods 47 work together with the die head 45 to further ensure the reliability of the bearing installation mechanism 40b in inserting the bearing 250 into the bottom shell 210. Furthermore, the cooperation between the rotary drive 42 and the lead screw and nut transmission assembly 44 improves the accuracy of bearing 250 insertion. Specifically, in Figure 10 As an example, the mold head 45 has a vacuum channel 451 and a large shaft section 452, a middle shaft section 453, and a small shaft section 454 arranged coaxially from top to bottom. The outlet 451 of the vacuum channel 451 is located on the large shaft section 452 to facilitate external air access for the operator. The inlet 4512 of the vacuum channel 451 is located on the end face 4531 of the middle shaft section 453 away from the large shaft section 452, and the inlet 4512 of the vacuum channel 451 is also arranged around the small shaft section 454. This design allows the mold head 45 to grip the bearing 250 by adsorption, center the bearing 250 with the help of the small shaft section 454, and axially limit the bearing 250 with the end face 4531 of the middle shaft section 453 away from the large shaft section 452, thereby more effectively improving the reliability of the bearing mounting mechanism 40b in installing the bearing 250 into the bottom shell 210. More specifically, in Figure 10In the example above, the end of the small shaft segment 454 furthest from the central shaft segment 453 is hemispherical 4541, which facilitates the insertion and removal of the small shaft segment 454 onto the bearing 250. It should be noted that the rotary drive 42 described above can be, but is not limited to, a motor. Furthermore, since the bearing pressing mechanism 40c and the bearing mounting mechanism 40b have the same structure, the bearing pressing mechanism 40c will not be described in detail here. In addition, the large shaft segment 452, the central shaft segment 453, and the small shaft segment 454 are named according to their diameters: the one with the largest diameter is called the large shaft segment 452, the one with the smallest diameter is called the small shaft segment 454, and the one with the middle diameter is called the central shaft segment 453.

[0042] like Figure 11 As shown, as an example, the fan blade mounting mechanism 50b includes a transverse drive 51 mounted on the support plate 20a, a transverse seat 52 mounted on the transverse drive 51, and each of the transverse seats 52 mounted and moving along the transverse direction of the transverse seat 52 (see...). Figure 11 The fan blade transfer module 53 and the fan blade pressing module 54 are separated by the direction indicated by the double arrows in the middle; this design allows the fan blade mounting mechanism 50b to pick up the fan blade 260 (see...) at the fan blade conveyor line 50e. Figure 13 While simultaneously installing the fan blades 260 into the base shell 210 on the tooling holder 11, the process is highly efficient. Specifically, at... Figure 11 In this example, the transverse actuator 51 can be, but is not limited to, a pneumatic or hydraulic cylinder; and the fan blade transfer module 53 can be a vertically lifting vacuum adsorption module, and the fan blade pressing module 54 can also be a vertically lifting vacuum adsorption module, but not limited to... Figure 11 The above is the limit.

[0043] Compared with existing technologies, the design utilizes a system consisting of "a stator pressing mechanism 20b, a gasket mounting mechanism 30, a buckle mounting mechanism 40a, a bearing mounting mechanism 40b, a bearing pressing mechanism 40c, an oiling mechanism 50c, a fan blade mounting mechanism 50b, a fan blade pressing mechanism 50c, a top cover mounting mechanism 60a, and a finished product unloading robot 70a, all mounted on the support plate 20a and arranged sequentially along the rotation direction of the turntable 10b." Furthermore, it incorporates a vibratory feeder mechanism 30a located next to the gasket mounting mechanism 30, and a bearing screening disc 40a located next to the bearing mounting mechanism 40b. The bearing 250 screened by the bearing screening disc 40d is transferred to the bearing transfer mechanism 40e directly below the bearing mounting mechanism 40b. An oil supply container 50d is provided next to the oiling mechanism 50a, a fan blade conveyor line 50e is provided next to the fan blade mounting mechanism 50b, and a top cover conveyor line 60b is provided next to the top cover mounting mechanism 60a. On the one hand, this enables the cooling fan assembly machine 100 of the present invention to realize the automatic assembly of cooling fans and the automatic unloading of finished products; on the other hand, it makes the arrangement of the cooling fan assembly machine 100 of the present invention more compact.

[0044] It is worth noting that since the oiling mechanism 50a, the fan blade mounting mechanism 50b, the top cover mounting mechanism 60a, and the bearing transfer mechanism 40e are already well known in the art, they will not be described in detail here. Additionally, the oiling mechanism 50a is used to apply oil to bearing 250.

[0045] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
