DETAILED DESCRIPTION

[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] See Figures 1-9The present invention discloses a cooling fan base assembly machine, including a loading platform, a retaining frame clamping assembly 20, a conveying assembly 30, a magnet clamping assembly 40, a wear-resistant sheet clamping assembly 50, a snap ring clamping assembly 60 and a bearing clamping assembly 70, and a workpiece carrier 11 and a workpiece carrier driving member 12 are provided on the loading platform, and two workpiece positioning grooves 111 are provided on the workpiece carrier 11. The workpiece positioning grooves 111 can match the structure of the fan base. The existing fan base has a triangularly distributed bracket structure, so the workpiece positioning grooves 111 have triangularly distributed positioning grooves that match the triangular brackets of the fan base. Therefore, after the fan base is placed in one of the positioning grooves of the workpiece carrier 11, it can match the structure of the fan base to achieve the positioning of the fan base.

[0040] The workpiece carrier 11 is rotatably mounted on the loading platform, and the workpiece carrier driver 12 is used to drive the workpiece carrier 11 to rotate. In the initial state, one of the positioning slots of the workpiece carrier 11 can be rotated to the position corresponding to the loading transfer assembly 10. After the loading transfer assembly 10 clamps the fan base and places it in one of the positioning slots, the workpiece carrier driver 12 drives the workpiece carrier 11 to rotate, so that the positioning slot at the other end of the workpiece carrier 11 rotates toward the loading transfer assembly 10, preparing for loading the next fan base. The workpiece positioning slot 111 with the fan base clamped can then face the holder clamping assembly 20 to perform the holder clamping action.

[0041] Specifically, the cage clamping assembly 20 includes a cage feeding mechanism 22 and a cage positioning mechanism 23. The cage positioning mechanism 23 includes a cage positioning platform 231, a positioning rod 232, and a positioning rod 232 driving member. The cage positioning platform 231 is provided with a positioning hole 2311. The cage positioning platform 231 can be connected to the end of the cage feeding mechanism 22, and the cage positioning platform 231 can receive the cage fed by the cage feeding mechanism 22. The positioning rod 232 driving member can drive the positioning rod 232 to move up and down to align the cage with the positioning hole 2311.

[0042] The conveying assembly 30 can receive the fan base with the holder clamped thereon, and convey the fan base with the holder clamped thereon along a conveying direction to the magnet clamping assembly 40 , the wear-resistant sheet clamping assembly 50 and the snap ring clamping assembly 60 in sequence.

[0043] The magnet clamping assembly 40 includes a magnet loading member 42 and a magnet clamping member 41. The magnet clamping member 41 can clamp the magnet on the magnet loading member 42 and transfer it to the fan base of the conveying assembly 30. The wear sheet clamping assembly 50 includes a wear sheet loading member 52, a wear sheet clamping member 51, and a wear sheet oiling member. The wear sheet loading member 52 can clamp the wear sheet from the wear sheet loading member 52. The wear sheet oiling member can oil the wear sheet. The wear sheet clamping member 51 is used to clamp the oiled wear sheet and transfer it to the fan base of the conveying assembly 30.

[0044] The snap ring clamping assembly 60 includes a snap ring loading member 62 and a snap ring gripping member 61. The snap ring gripping member 61 is used to grip the snap ring from the snap ring loading member 62 and transfer it to the fan base of the conveyor assembly 30. The bearing clamping assembly 70 is connected to the end of the conveyor assembly 30 and is used to clamp the bearing to the fan base.

[0045] Based on the above structure, when using the cooling fan base assembly machine of the present invention, the fan base is transferred to the workpiece positioning groove 111 on the workpiece carrier 11 through the loading transfer component 10, and then the workpiece carrier driving component 12 drives the workpiece carrier 11 to rotate, so that the fan base on the workpiece positioning groove 111 faces the retaining frame clamping component 20, and the workpiece positioning groove 111 at the other end of the workpiece carrier 11 can be rotated to the loading position to prepare for loading the next fan base.

[0046] When clamping the retainer, the retainer can be transported to the retainer positioning platform 231 through the retainer feeding mechanism 22. After receiving the retainer, the retainer positioning platform 231 can correspond to the positioning hole 2311. In order to enable the retainer to be accurately assembled with the center axis of the fan base, the positioning rod 232 is driven by the positioning rod 232 to move downward, and the positioning rod 232 can be inserted downward into the center hole of the retainer. After insertion, it corresponds to the positioning hole 2311 to achieve the center positioning of the retainer.

[0047] Afterwards, the retainer gripper 21 can grip the positioned retainer on the retainer positioning platform 231 and clamp it to the central axis of the fan base on the workpiece positioning groove 111, thereby positioning and clamping the retainer and the fan base. After the retainer is clamped to the fan base, the loading and transfer assembly 10 can transfer the fan base to the conveyor assembly 30.

[0048] The conveying assembly 30 can convey the fan base with the holder clamped thereon to the corresponding position of the magnet clamping assembly 40, where the magnets of the fan base are loaded and clamped. During the magnet clamping, the magnet loading member 42 can convey the magnets for magnet loading, and the magnet clamping member 41 can clamp the magnets on the magnet loading member 42 and clamp them into the holder of the fan base, thereby loading and clamping the magnets in the holder of the fan base.

[0049] After the magnet is clamped to the holder of the fan base, the conveying assembly 30 conveys the fan base to the position of the wear-resistant sheet clamping assembly 50. After the fan base reaches this position, the wear-resistant sheet can be clamped. When loading and clamping the wear-resistant sheet, the wear-resistant sheet can be loaded by the wear-resistant sheet loading component 52, and then the wear-resistant sheet clamping component 51 can clamp the wear-resistant sheet to the magnet of the holder of the fan base to clamp the wear-resistant sheet.

[0050] After the wear-resistant sheet is clamped to the fan base holder, the conveying assembly 30 conveys the fan base to the position of the snap ring clamping assembly 60. After the fan base reaches this position, the snap ring can be clamped. When loading and clamping the snap ring, the snap ring can be loaded by the snap ring loading component 62, and then the snap ring clamping component 61 can clamp the snap ring to the wear-resistant sheet of the fan base holder to clamp the snap ring.

[0051] After the retaining ring is clamped to the retaining frame of the fan base, the conveying assembly 30 can continue to convey the fan base to the bearing clamping assembly 70, and the bearing is loaded and clamped at the position of the bearing clamping assembly 70. In this way, the fan base, retaining frame, magnet, wear-resistant plate, retaining ring and bearing can be automatically clamped in sequence. After clamping is completed, unloading can be carried out. The degree of automation is high. When the corresponding workstation is clamping the parts, the fan base of the previous workstation is clamping the previous part. The clamping process is continuous, which improves the efficiency of the automatic assembly of the fan.

[0052] In addition, since the retaining frame of the fan base is the basis for the subsequent clamping of magnets, wear-resistant sheets, retaining rings and bearings, the accuracy of its clamping is particularly important. Therefore, in this application, before the retaining frame is clamped, the downward movement of the positioning rod 232 is coordinated with the positioning hole 2311 to achieve the center positioning of the retaining frame, so that the retaining frame can be positioned and clamped with the center axis of the fan base, thereby improving the clamping accuracy of the retaining frame and making the clamping accuracy of the subsequently clamped magnets, wear-resistant sheets, retaining rings and bearings higher.

[0053] Furthermore, in this embodiment, the bearing clamping assembly 70 includes a bearing loading part, a bearing positioning mechanism, a bearing clamping part and a turntable 71 mechanism, and the bearing positioning mechanism includes a bearing positioning platform 72 and a positioning carrier. The above-mentioned positioning carrier is rotatably arranged on the bearing positioning platform 72, and the bearing loading part can be loaded onto the positioning carrier, and the bearing clamping part clamps the bearing on the positioning carrier and transfers it to the turntable 71 mechanism.

[0054] Specifically, the turntable 71 mechanism includes a turntable 71, a turntable 71 driving member and a plurality of spotting guns 74. A plurality of workpiece clamping platforms 711 are provided on the turntable 71. The workpiece clamping platforms 711 are also provided with a workpiece positioning groove 111 with the same structure as the above-mentioned workpiece carrier 11, and the turntable 71 driving member can drive the turntable 71 to rotate. The plurality of workpiece clamping platforms 711 are distributed at intervals in the circumferential direction of the turntable 71, and the plurality of spotting guns 74 are distributed on the outer periphery of the turntable 71 and are distributed at intervals along the rotation direction of the turntable 71; the spotting guns 74 are used to spot the workpieces on the workpiece clamping platforms 711.

[0055] It should be noted that a plurality of spotting gun driving members 742 may be provided on the turntable 71 , each spotting gun driving member 742 corresponding to a spotting gun 74 , which may drive the spotting gun 74 to move up and down. During the up and down movement, the spotting gun 74 spots the workpiece on the turntable 71 .

[0056] Based on this structure, the conveying assembly 30 transports the fan base clamped with the retaining frame, magnet, wear-resistant plate and retaining ring to the end, and then a transfer clamp 733 can be set on the bearing clamping part. The transfer clamp 733 can grab the fan base at the end of the conveying assembly 30 and transfer it to the workpiece clamping table 711 of the turntable 71. The fan base is positioned and clamped using the workpiece positioning groove 111 on the workpiece clamping table 711, and then the bearing clamping action is started.

[0057] The bearing is transported through the bearing loading piece, and the bearing clamping piece can clamp the bearing to the positioning platform of the bearing positioning table 72. The positioning platform can be rotated under the drive of the positioning platform driving piece, so that the bearing on the positioning platform is rotated to an angle matching the clamping structure of the retaining frame. Then the bearing clamping piece can clamp the positioned bearing to the fan base on the workpiece clamping table 711 of the turntable 71 to perform positioning and clamping of the bearing and provide bearing accuracy.

[0058] Specifically, four spotting guns 74 may be provided, and the four spotting guns 74 are spaced apart in the direction of rotation of the turntable 71. After the fan base is transported to the end in the transport direction of the conveying assembly 30, a retaining frame, a magnet, a wear-resistant sheet, and a clamping ring structure have been clamped on the fan base in sequence. Thereafter, the fan base on the conveying assembly 30 is clamped by the transfer clamp 733 on the bearing clamping member, and transferred to the workpiece clamping table 711 on the turntable 71. Thereafter, the bearing positioning table 72 is positioned by the magnetic attraction magnet 7311 of the bearing clamping member. The bearing is transferred to the fan base on the turntable 71. Thereafter, the turntable 71 is driven to rotate by the turntable 71 driving member and passes through four spotting guns 74 in sequence. The four spotting guns 74 are respectively used to apply lubricating oil, bearing accelerator, bearing anaerobic agent and bearing oil repellent on the bearing points of the fan base. That is, after the bearing is clamped with the retaining frame of the fan base, the lubricating oil, accelerator, anaerobic agent and oil repellent can be automatically applied to the bearing, which facilitates the direct clamping of the motor shaft and the bearing of the fan base in the later stage, and prevents the bearing from oxidation, oil leakage and the like in the later stage.

[0059] It should be noted that a spotting slot 76 and a spotting slot 76 driving member may also be provided on the turntable 71 , and a spotting slot 76 and a spotting slot 76 driving member may be provided at a position corresponding to each spotting gun 74 . The spotting slot 76 is filled with the corresponding spotting liquid. When spotting, the spotting slot 76 driving member drives the spotting slot 76 to move toward the spotting gun 74 , and the spotting gun tip 741 of the spotting gun 74 may dip the sample liquid in the spotting slot 76 for spotting.

[0060] Furthermore, a plurality of spotting detection mechanisms 75 may be provided on the turntable 71, and the spotting detection mechanisms 75 include spotting cameras and spotting camera driving components. The plurality of spotting detection mechanisms 75 are arranged corresponding to the plurality of spotting guns 74, that is, a spotting camera is provided at the position where each spotting gun 74 is arranged, and the spotting camera driving component can be used to drive the spotting camera to move closer to or away from the workpiece clamping table 711. When spotting, the spotting camera driving component drives the spotting camera to move up and down or left and right, so that it can be aligned with the fan base on the workpiece clamping table 711 on the turntable 71 to achieve positioning of the fan base. The spotting gun driving component 742 can drive the spotting gun 74 to spot according to the detection position of the spotting camera, thereby achieving accurate spotting of the fan base and higher spotting accuracy.

[0061] It should be noted that the above-mentioned cage loading parts and bearing loading parts can be realized by using vibration plate loading parts in the prior art, and the vibration of the vibration plate is used to output the vibration of the cage and bearing to the conveying track to realize loading.

[0062] Furthermore, the bearing clamping member includes a bearing suction member 731 and a suction member driving member 732. Specifically, a suction magnet 7311 is provided at the bottom end of the suction member. The suction member driving member drives the suction member to move between the positioning platform and the turntable 71. The suction member driving member can drive the suction member to move up and down, left and right, and front and back, while the suction magnet 7311 can absorb the bearing. On the basis of this structure, in order to facilitate the transfer and clamping of the bearing by the bearing clamping member, the suction member driving member 732 can be provided with a driving frame. The above-mentioned suction member and the above-mentioned transfer clamping claw 733 are all installed on the driving frame. On the moving frame, the suction member driving member can drive the driving frame to move up and down, left and right, and forward and backward, so that the transfer clamp 733 on the driving frame can grab the fan base for transfer, and the suction member on the driving frame uses the suction magnet 7311 to absorb the bearing. When clamping the bearing, the bearing on the suction magnet 7311 can be placed in the retaining frame of the fan base, and then the suction member driving member drives the driving frame to move downward and press it into the retaining frame. The bearing and the retaining frame are tightly assembled, and the suction magnet 7311 can be separated from the bearing to start the next bearing suction and transfer action.

[0063] Of course, a transfer clamp driving member 734 can also be set on the driving frame. The transfer clamp driving member 734 drives the transfer clamp 733 to rotate relative to the driving frame, and the assembly angle of the fan base to the workpiece clamping table 711 on the turntable 71 can be adjusted.

[0064] Furthermore, the cooling fan base assembly machine also includes a material transfer assembly 80. Multiple spot detection mechanisms 75 and the material transfer assembly 80 are sequentially distributed along the rotational direction of the turntable 71. The material transfer assembly 80 is used to clamp the fan base on the workpiece clamping table 711 and perform material removal. As the turntable 71 rotates, the multiple spot detection mechanisms 75, in conjunction with the multiple spot guns 74, automatically apply lubricating oil, accelerator, anaerobic agent, and oil repellent to the bearings. After this, the turntable 71 rotates to the material transfer assembly 80, where the fan base, clamped by the material transfer assembly 80, is removed.

[0065] It should be noted that the above-mentioned loading and transferring assembly 10 and unloading and transferring assembly 80 can both be implemented by multi-axis robots in the prior art or by structures such as manipulators.

[0066] Further, see Figure 7 The magnetic loading component 42 includes a magnetic loading platform, multiple magnetic loading tubes 422, a pushing block 423 and a pushing block driving component 425. A magnetic loading rack 421 and a magnetic loading rack driving component 424 are provided on the magnetic loading platform. The magnetic loading rack 421 is rotatably installed on the magnetic loading platform, and the magnetic loading rack driving component 424 drives the magnetic loading rack 421 to rotate.

[0067] Specifically, a plurality of drop holes are provided on the magnet loading rack 421, and a plurality of magnet loading tubes 422 are mounted on the magnet loading rack 421, with each magnet loading tube 422 corresponding to each of the drop holes. A pusher block 423 is provided with a pusher trough 4231, which is located below the magnet loading rack 421 and corresponds to one of the drop holes. A pusher block driver 425 is used to drive the pusher block 423 back and forth. A magnet gripper 41 is used to grip the magnet within the pusher trough 4231.

[0068] When loading magnets, multiple magnets can be stacked in multiple magnet loading tubes 422. When loading magnets, the magnet loading rack driving component 424 drives the magnet loading rack 421 to rotate, so that one of the blanking holes on the magnet loading rack 421 corresponds to the pushing groove 4231 on the pushing block 423, and the height of the pushing groove 4231 is the height of one magnet.

[0069] When one of the drop holes corresponds to the pushing groove 4231, a magnet falls into the pushing groove 4231. Thereafter, the pushing block driving component 425 is started, and the pushing block driving component 425 drives the pushing block 423 to withdraw forward, so that the pushing groove 4231 on the pushing block 423 is exposed, and then the magnet clamping component 41 can clamp the magnet in the pushing groove 4231 for magnet clamping and transfer.

[0070] After the magnet in the pusher block 423 is taken out, the pusher block driving member 425 drives the pusher block 423 to return to the pusher slot 4231 corresponding to the blanking hole, and the next magnet is blanked in the magnet feeding tube 422, and so on. After the magnet in one magnet feeding tube 422 is loaded, the magnet feeding rack driving member 424 drives the magnet feeding rack 421 to rotate so that the blanking hole of the next magnet feeding tube 422 corresponds to the pusher slot 4231 of the pusher block 423, and the magnets are continuously loaded. In this way, the pusher block 423 can be moved back and forth to realize the separate loading of each magnet, and the rotation of the magnet feeding rack 421 can drive different magnet feeding tubes 422 to continuously transport and load magnets.

[0071] Further, see Figure 8 as well as Figure 9 The wear-resistant sheet loading component 52 includes a loading barrel 521, a push plate 522, and a push plate driving component 524. A loading chamber 5211 is provided in the loading barrel 521, and a blanking port 5212 is provided at the bottom end of the loading chamber 5211. Specifically, a toggle plate 525 and a toggle plate driving component 523 are provided in the loading barrel 521. The toggle plate 525 is rotatably installed in the loading chamber 5211, and the toggle plate driving component 523 is installed at the top of the loading barrel 521. The toggle plate driving component 523 can rotate the toggle plate 525, and the toggle plate 525 pushes the wear-resistant sheet to the blanking port 5212 during the rotation process.

[0072] The above-mentioned pushing plate 522 is arranged below the upper barrel 521, and the pushing plate 522 can move back and forth below the upper barrel 521. A receiving groove 5221 is provided on the pushing plate 522, and the receiving groove 5221 can correspond to or stagger with the blanking port 5212 under the drive of the pushing plate driving member 524; the wear-resistant sheet clamping member 51 is used to clamp the wear-resistant sheet in the receiving groove 5221.

[0073] Based on this structure, when loading the wear-resistant sheets, multiple wear-resistant sheets are placed in the loading chamber 5211 of the loading barrel 521. In the initial state, the receiving groove 5221 of the pushing plate 522 can correspond to the position of the blanking port 5212. The height of the receiving groove 5221 is the same as the height of the wear-resistant sheet, so that the receiving groove 5221 can only receive one wear-resistant sheet at a time.

[0074] When pushing the wear-resistant sheet, the toggle sheet 525 is driven to rotate by the toggle sheet driving member 523. The toggle sheet 525 rotates in the loading chamber 5211, and can push the wear-resistant sheet to the blanking port 5212, and fall into the receiving groove 5221 through the blanking port 5212. After that, the pushing plate driving member 524 drives the pushing plate 522 to move forward, and the receiving groove 5221 on the pushing plate 522 is staggered with the blanking port 5212. The other positions of the pushing plate 522 close the blanking port 5212, and the receiving groove 5221 is exposed. The wear-resistant sheet clamping member 51 can clamp the wear-resistant sheet in the receiving groove 5221, and then transfer and clamp the wear-resistant sheet to the retaining frame of the fan base.

[0075] It should be noted that the continuous rotation of the toggle piece 525 can continuously toggle and push the wear-resistant sheet in the feeding chamber 5211. Specifically, a conical guide surface can be provided at the bottom end of the feeding chamber. After the wear-resistant sheet is placed in the feeding chamber 5211, it can be guided by the conical guide surface and fall to the bottom end of the feeding chamber 5211. The conical guide surface can prevent the wear-resistant sheet from accumulating, so that the wear-resistant sheet is dispersed in the feeding chamber 5211 and is more easily pushed to the drop opening 5212 by the toggle piece 525.

[0076] Furthermore, the structure of the retaining ring loading part 62 in this embodiment is the same as that of the wear-resistant sheet loading part 52. The specific retaining ring loading process is consistent with the wear-resistant sheet loading process, and will not be described in detail here.

[0077] What is different from the loading process of the wear-resistant sheet is that when the wear-resistant sheet is loaded, after the wear-resistant sheet clamping part 51 clamps the wear-resistant sheet, it can first drive the clamped wear-resistant sheet to move to the wear-resistant sheet oiling part position, and oil the wear-resistant sheet through the wear-resistant sheet oiling part, and then clamp the wear-resistant sheet after oiling.

[0078] The above-mentioned wear-resistant plate oiling part can also use the oiling gun in the existing technology. After dipping the oil gun into the oil in the oil tank, the oil is applied to the wear-resistant plate. In this way, both sides of the wear-resistant plate are stained with oil, and there is oil between one side of the wear-resistant plate and the magnet. After the retaining ring is clamped, there is also oil between the other side of the wear-resistant plate and the retaining ring, which makes it more lubricated in later use.

[0079] Furthermore, the conveying assembly 30 also includes a plurality of positioning fixtures 31, which are spaced apart in the conveying direction. The magnet clamping assembly 40, the wear-resistant sheet clamping assembly 50, and the snap ring clamping assembly 60 are each provided with a corresponding positioning fixture 31. Thus, when the conveying assembly 30 is sequentially conveyed to the magnet clamping assembly 40, the wear-resistant sheet clamping assembly 50, and the snap ring clamping assembly 60, the positioning fixtures 31 at the corresponding positions can clamp the central axis of the fan base at that position of the conveying assembly 30, thereby achieving central positioning and enabling the magnet to be positioned and clamped.

[0080] Furthermore, the positioning fixture 31 in this embodiment includes a positioning frame, two positioning arms, a positioning arm driver and a positioning frame driver, and the two positioning arms are arranged at intervals on the positioning frame; the positioning arm driver can drive the two positioning arms to approach or move away from each other, and the positioning arms are provided with arc positioning grooves; the arc positioning grooves of the two positioning arms form an annular positioning groove after approaching each other; the positioning frame driver is used to drive the positioning frame to move close to or away from the conveying end face of the conveying assembly 30.

[0081] In this way, when positioning the fan base, after the fan base is transported to the positioning fixture 31 by the conveying assembly 30, the positioning frame driving member can drive the positioning frame to move toward the fan base on the conveying end surface, and the two positioning arms on the positioning frame can be respectively located on both sides of the central axis of the fan base, and then the two positioning arms are driven close to each other by the positioning arm driving member, and the arc positioning grooves of the two positioning arms can move close to the outside of the central axis, holding the central axis of the fan base on both sides, so that the central axis of the fan base can be centered by the annular positioning groove, so as to position the central axis of the fan base, and facilitate the center positioning and clamping of the retaining frame, magnet, wear-resistant plate and retaining ring, so that the clamping accuracy is higher.

[0082] Specifically, a positioning detection camera 32 is provided above each positioning fixture 31 to photograph and locate the fan base clamped by the positioning fixture 31 , and the corresponding components can be accurately clamped according to the shooting results of the positioning detection camera 32 .

[0083] In addition, a positioning detection sensor 33 is provided on the side of the corresponding positioning fixture 31. When the conveying component 30 conveys the fan component to the positioning fixture 31 at the corresponding position, the positioning detection sensor 33 can send position information, and the positioning fixture 31 can perform positioning and clamping actions according to the positioning.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
