Description

Technical Field

[0001] This utility model relates to the field of fan assembly technology, and in particular to a device for assembling fans. Background Technology

[0002] As a core component of thermal management for electronic devices, the assembly precision and efficiency of cooling fans directly affect product reliability and mass production costs. In the existing technology, the assembly process of fan impeller components generally adopts a semi-automated process: first, the operator manually positions the oil seal into the central shaft hole of the fan impeller, then operates the pressing equipment to press it into the fan impeller, then inserts the magnetic ring, and presses it again.

[0003] This type of semi-manual assembly mode has significant drawbacks. The pre-positioning of oil seals and magnetic rings requires manual picking, alignment and placement one by one. The operation cycle is limited by the skill level of the personnel and the accumulation of fatigue, making it difficult to achieve continuous and efficient operation and unable to be integrated into the fully automated assembly production process. Utility Model Content

[0004] The purpose of this invention is to provide a device for assembling fans, which enables automated feeding and pressing assembly.

[0005] The technical solution adopted by the device for assembling fans disclosed in this utility model is:

The second rotary motor is fixedly connected to the lifting slide plate, and a magnetic rod is fixedly connected to the output shaft of the second rotary motor. A positioning post is fixedly connected to one end of the magnetic rod, and the positioning post is located below the positioning ring. The feeding cylinder drives the material trough to move back and forth between the bottom of the material hole and the bottom of the positioning post.

[0010] As a preferred embodiment, the second hopper includes a second support bracket and a pusher plate. The second support bracket is fixedly connected to the workbench. A first carrier plate with a certain angle is fixedly connected to the second support bracket. A second carrier plate is fixedly connected to one side of the first carrier plate.

A gear that meshes with the rack is fixedly connected to the output shaft of the pusher motor. A guide plate is fixedly connected to one end of the first carrier plate. The outlet of the guide plate is connected to a guide assembly.

[0011] As a preferred embodiment, the transfer assembly includes a third rotary motor, which is fixedly connected to the second support bracket. A lifting cylinder is fixedly connected to the output shaft of the third rotary motor, and a clamping cylinder is fixedly connected to the output shaft of the lifting cylinder. The third rotary motor drives the clamping cylinder to move back and forth between the other carrier of the first rotary table and the discharge port of the material guiding assembly.

[0012] As a preferred embodiment, the pressing mechanism includes a pressing screw device, on which a pressing slide plate is slidably connected, and a pressing block is fixedly connected to the bottom of the pressing slide plate, the pressing block being located above another carrier of the two rotary tables.

[0013] As a preferred embodiment, both the first rotary table and the second rotary table include a first rotary motor, the first rotary motor is fixedly connected to the top of the worktable, and the output shaft of the first rotary motor is fixedly connected to the middle of the rotary plate.

[0014] As a preferred embodiment, the reciprocating mechanism includes a base, the reciprocating slide plate is slidably connected to the base, a connecting plate is fixedly connected to the base, a reciprocating cylinder is fixedly connected to the reciprocating slide plate, and the output shaft of the reciprocating cylinder is fixedly connected to the connecting plate.

[0015] As a preferred embodiment, the unloading mechanism includes an unloading screw device, which is fixedly connected to the top of the worktable. An unloading slide plate is slidably connected to the unloading screw device, and an unloading cylinder is fixedly connected to the unloading slide plate. A second gripping suction cup is fixedly connected to the output shaft of the unloading cylinder.

[0016] The beneficial effects of the device for assembling fans disclosed in this utility model are:

[0017] The feeding mechanism conveys the fan impeller toward the positioning seat. The reciprocating slide slides back and forth toward the feeding mechanism or the unloading mechanism under the drive of the reciprocating mechanism, so that the gripping cylinder at the head of the reciprocating slide transfers the fan impeller to the positioning ring through the first gripping suction cup. After the assembly component takes out the oil seal from the first material bin and pre-presses it into the fan impeller through the positioning ring, the first gripping suction cup of the head gripping cylinder releases the fan impeller.

[0018] The transfer assembly extracts the magnetic ring from the second hopper and places it into one of the empty carriers on the second rotary table. The first rotary table drives the rotating plate to rotate 180°, allowing the transfer assembly to place the magnetic ring into another empty carrier on the second rotary table, thus realizing the alternating feeding of the two carriers on the first rotary table. The gripping cylinder located in the middle of the reciprocating slide transfers the fan impeller with the oil seal pre-pressed into place above the magnetic ring. After the fan impeller is pre-fitted into the outside of the magnetic ring, the first gripping suction cup of the middle gripping cylinder releases the fan impeller.

[0019] The gripping cylinder at the tail of the reciprocating slide transfers the pre-installed impeller with oil seals and magnetic rings to the empty carrier on the second rotary table. Then, the first gripping suction cup of the tail gripping cylinder releases the impeller, and the second rotary table drives the rotating plate to rotate 180°, allowing the pressing mechanism to completely press the oil seals and magnetic rings into the impeller. The second rotary table then drives the rotating plate to rotate 180° again, allowing the unloading mechanism to remove the pressed impeller and free up the empty carrier. This achieves alternating unloading and simultaneous loading and pressing of the two carriers on the second rotary table. By automating the placement of oil seals and magnetic rings into the impeller and performing pressing, assembly efficiency is improved. Attached Figure Description

[0038] The unloading mechanism 3 includes an unloading screw device 31; the unloading screw device 31 is fixedly connected to the top of the worktable 1.

[0041] Furthermore, a slider is fixedly connected to the top of the base 41, and a reciprocating slide plate 42 is slidably connected to the reciprocating mechanism 4.

[0042] Furthermore, a reciprocating cylinder 421 is fixedly connected to the reciprocating slide plate 42. The output shaft of the reciprocating cylinder 421 is parallel to the table surface of the worktable 1. The slide rail is parallel to the output shaft of the reciprocating cylinder 421. The output shaft of the reciprocating cylinder 421 is fixedly connected to the connecting plate.

[0043] Furthermore, three equally spaced gripping cylinders 422 are fixedly connected to the reciprocating slide plate 42, and the output shaft of the gripping cylinder 422 is provided with a first gripping suction cup.

[0044] The output shaft of the reciprocating cylinder 421 pushes the reciprocating slide plate 42 to slide towards the feeding mechanism 2, so that the three gripping cylinders 422 are respectively located above the feeding mechanism 2, above the positioning ring 111, and above one of the carriers 123 of the first rotating table 12; the output shaft of the reciprocating cylinder 421 pulls the reciprocating slide plate 42 to slide towards the unloading mechanism 3, so that the three gripping cylinders 422 are respectively located above the positioning ring 111, above one of the carriers 123 of the first rotating table 12, and above one of the carriers 123 of the second rotating table 13.

[0045] Please refer to Figure 2 and Figures 3-6 .

[0046] The workbench 1 is equipped with a first material bin 5 and an assembly component 55. The assembly component 55 is located near the discharge port of the first material bin 5 and below the positioning ring 111. The first material bin 5 includes a first support bracket 51. The first support bracket 51 is fixedly connected to the bottom of the workbench 1. A feeding cylinder 52 is fixedly connected to the first support bracket 51. A material tray 521 is slidably connected to the first support bracket 51. The output shaft of the feeding cylinder 52 is fixedly connected to the material tray 521. A material groove 522 is opened on the top of the material tray 521. In this embodiment, the depth of the material groove 522 is preferably equal to the length of the oil seal. The output shaft of the feeding cylinder 52 pushes or pulls the material tray 521 to slide back and forth on the first support bracket 51.

[0047] Furthermore, a material box 53 is provided on the first support bracket 51. The inside of the material box 53 is used to store the oil seal. A material hole 531 is opened at the bottom of the material box 53. In this embodiment, it is preferred that the diameter of the material hole 531 is larger than the diameter of the oil seal and the diameter of the material hole 531 is smaller than the length of the oil seal. A slope is opened at the bottom of the material box 53, and the low point of the slope is close to the material hole 531.

[0048] Furthermore, a rotating shaft 532 is rotatably connected inside the material box 53, and a plurality of material brushes 533 are fixedly connected to the outside of the rotating shaft 532. In this embodiment, three material brushes 533 are preferably arranged at intervals around the outside of the rotating shaft 532. A drive motor 54 is fixedly connected to the outside of the material box 53, and the output shaft of the drive motor 54 is fixedly connected to the rotating shaft 532.

[0049] Furthermore, an air blowing device 534 is fixedly connected to the outside of the material box 53;

[0050] The output shaft of the drive motor 54 drives three material brushes 533 to rotate inside the material box 53 via the rotating shaft 532. When the material brushes 533 sweep the multiple oil seals inside the material box 53, a single oil seal will fall into the material hole 531. The output shaft of the feeding cylinder 52 pulls the material tray 521 into the first support bracket 51, so that the material groove 522 is coaxial with the material hole 531. The oil seal falls into the material groove 522. The output shaft of the feeding cylinder 52 pushes the material tray 521 to slide out of the first support bracket 51 carrying the oil seal. The air outlet of the air blowing device 534 faces the oil seal on the material tray 521, and the air blowing device 534 blows away the dust attached to the oil seal.

[0051] Assembly component 55 includes a lifting screw device 551 and a second rotary motor 553; the lifting screw device 551 is fixedly connected to the bottom of the worktable 1, and a lifting slide plate 552 is slidably connected to the lifting screw device 551; the second rotary motor 553 is fixedly connected to the lifting slide plate 552, and a magnetic rod 554 is fixedly connected to the output shaft of the second rotary motor 553, and a positioning post 555 is fixedly connected to one end of the magnetic rod 554;

[0052] Furthermore, a slot runs through the workbench 1, the slot is located below the positioning ring 111, the positioning post 555 is located below the positioning ring 111, and the feeding cylinder 52 drives the material trough 522 to move back and forth between the material hole 531 and the positioning post 555.

[0053] After the material tray 521 carrying the oil seal slides to below the magnetic rod 554, the second rotary motor 553 drives the magnetic rod 554 to rotate 180°, so that the positioning post 555 faces the oil seal in the material hole 531. The lifting screw device 551 drives the positioning post 555 to descend and enter the center hole of the oil seal through the lifting slide plate 552. The positioning post 555 and the center hole of the oil seal are in clearance fit. The magnetic rod 554 uses magnetic force to attract the oil seal. The lifting screw device 551 drives the magnetic rod 554 carrying the oil seal to rise through the lifting slide plate 552. During the rising process, the second rotary motor 553 drives the magnetic rod 554 to rotate another 180°, so that the positioning post 555 faces the center point of the positioning ring 111. Driven by the lifting screw device 551, the oil seal passes through the slot and the positioning ring 111 and is pre-pressed into the fan impeller 8.

[0054] Please refer to Figure 1 and Figures 7-9 .

[0055] The workbench 1 is provided with a second material bin 6, which includes a second support bracket 61 and a pusher plate 62. The second support bracket 61 is fixedly connected to the top of the workbench 1. A first carrier plate 611 is fixedly connected to the second support bracket 61. The first carrier plate 611 is tilted at a certain angle on the second support bracket 61. In this embodiment, the first carrier plate 611 is preferably tilted at 45° on the second support bracket 61. A second carrier plate 612 is fixedly connected to one side of the first carrier plate 611. Multiple magnetic rings 81 are stacked into multiple rows. The multiple rows of magnetic rings 81 are placed on the top of the tilted first carrier plate 611. The second carrier plate 612 supports the multiple rows of magnetic rings 81.

[0056] Furthermore, a rack 613 is fixedly connected to the first carrier plate 611, and a sliding groove 614 passes through the first carrier plate 611. The rack 613 and the sliding groove 614 are parallel to each other. Two smooth rods 615 are fixedly connected to both sides of the first carrier plate 611, and the sliding groove 614 and the smooth rods 615 are parallel to each other. A pusher plate 62 is placed on the first carrier plate 611. The two sides of the pusher plate 62 are slidably connected to the two smooth rods 615 respectively. A connecting part extends from the pusher plate 62 and passes through the sliding groove 614. A pusher motor 621 is fixedly connected to the connecting part of the pusher plate 62. A gear is fixedly connected to the output shaft of the pusher motor 621, and the gear meshes with the rack 613.

[0057] Furthermore, a guide plate 63 is fixedly connected to one end of the first carrier plate 611. The width of the guide plate 63 is greater than the width of the first carrier plate 611, and the outlet of the guide plate 63 is connected to a guide assembly.

[0058] Furthermore, the material guiding assembly includes a material guiding box 64, the outlet of the material guiding plate 63 is connected to the material guiding box 64, the material guiding box 64 and the first carrier plate 611 are tilted synchronously at the same angle; a material guiding cylinder 641 is fixedly connected to the top of the material guiding box 64, a material guiding block 642 is slidably connected inside the material guiding box 64, the output shaft of the material guiding cylinder 641 passes through the material guiding box 64 and is fixedly connected to the material guiding block 642, a limit block 643 is fixedly connected to the bottom of the material guiding box 64, the material guiding block 642 and the limit block 643 are respectively located at both ends of the outlet of the material guiding box 64, and the outlet of the material guiding box 64 is located on one side of the material guiding box 64;

[0059] The output shaft of the pusher motor 621 drives the gear to rotate. The gear pushes the pusher plate 62 to slide on the first carrier plate 61 by a distance equal to the diameter of a magnetic ring 81 through the rack 613. This pushes a row of magnetic rings 81 close to the guide plate 63 into the guide plate 63. Due to their weight, the magnetic rings 81 slide to the outlet of the guide plate 63. The design of the guide plate 63, which is wider than the first carrier plate 611, allows the guide plate 63 to guide more magnetic rings 81 to its outlet, preventing insufficient number of magnetic rings 81 and their light weight from being attracted by the adjacent row of magnetic rings 81.

[0060] Since multiple magnetic rings 81 are sequentially attracted to each other, the output shaft of the guide cylinder 641 needs to push the guide block 642 to push the magnetic ring 81 at the first end away from the row of magnetic rings 81 and push the magnetic ring 81 to the discharge port of the guide box 64. The magnetic ring 81 will be clamped and constrained at the discharge port of the guide box 64 by the guide block 642 and the limiting block 643. When the clamping cylinder 653 clamps the magnetic ring 81 in the discharge port of the guide box 64, the output shaft of the guide cylinder 641 pulls the guide block 642 to reset and release the constraint on the magnetic ring 81, preparing to push the next magnetic ring 81 to the discharge port of the guide box 64.

[0061] The second hopper 6 is equipped with a transfer assembly 65, which is close to the discharge port of the second hopper 6 and another carrier 123 of the first rotary table 12. The transfer assembly 65 includes a third rotary motor 651.

[0062] Furthermore, the third rotary motor 651 is fixedly connected to the second support bracket 61, and a lifting cylinder 652 is fixedly connected to the output shaft of the third rotary motor 651. A clamping cylinder 653 is fixedly connected to the output shaft of the lifting cylinder 652. The third rotary motor 651 drives the clamping cylinder 653 to move back and forth between the other carrier 123 of the first rotary table 12 and the discharge port of the guide box 64.

[0063] The output shaft of the third rotary motor 651 drives the lifting cylinder 652 to rotate 135°, causing the clamping cylinder 653 to face the discharge port of the guide box 64. The lifting cylinder 652 pushes the clamping cylinder 653 to approach and penetrate the inner ring of the magnetic ring 81 inside the discharge port of the guide box 64. The clamping cylinder 653 drives the two grippers to open and touch the inner ring of the magnetic ring 81. The lifting cylinder 652 pulls the clamping cylinder 653 to reset and remove the magnetic ring 81 from the discharge port of the guide box 64. The output shaft of the three rotary motor 651 drives the lifting cylinder 652 to rotate 135° in the opposite direction, so that the clamping cylinder 653 faces the other carrier 123 of the first rotary table 12. The lifting cylinder 652 pushes the clamping cylinder 653 down, and the gripper of the clamping cylinder 653 releases the magnetic ring 81, so that the magnetic ring 81 is placed on the carrier 123 of the first rotary table 12. Since the gripper of the clamping cylinder 653 is made of non-metallic material, the magnetic ring 81 will not be attracted.

[0064] Please refer to Figure 1 and Figure 10 .

[0065] A pressing mechanism is provided on the workbench. The pressing mechanism is close to another carrier 123 of the second rotary table 13. The pressing mechanism 7 includes a pressing screw device 71. A pressing slide plate 711 is slidably connected to the pressing screw device 71. A pressing block 712 is fixedly connected to the bottom of the pressing slide plate 711. The pressing block 712 is located above the other carrier 123 of the second rotary table 13.

[0066] The pressing screw device 71 drives the pressing block 712 to descend via the pressing slide plate 711. The pressing block 712 touches the fan impeller 8, pressing the oil seal and magnetic ring 81 completely into the fan impeller 8. After pressing is completed, the pressing screw device 71 drives the pressing block 712 to rise and reset via the pressing slide plate 711, waiting for the next round of pressing.

[0067] Please refer to Figures 1-10 .

[0068] When the device is running:

[0069] The fan impeller 8 is transferred to the positioning seat 11 by the feeding mechanism 2. The reciprocating mechanism 4 drives the reciprocating slide plate 42 to move towards the feeding mechanism 2, so that the gripping cylinder 422 located at the head of the reciprocating slide plate 42 moves to the top of the fan impeller 8 on the feeding mechanism 2. After the output shaft of the first gripping cylinder 422 pushes the first gripping suction cup to descend and adsorb the fan impeller 8, the output shaft of the first gripping cylinder 422 pulls the first gripping suction cup to rise and reset. The reciprocating mechanism 4 drives the reciprocating slide plate 42 to move towards the unloading mechanism 3. The first gripping cylinder 422 transfers the fan impeller 8 to the top of the positioning ring 111 and presses the fan impeller 8 on the positioning ring 111. The assembly component 55 takes out the oil seal from the first hopper 5 and pre-presses it into the fan impeller 8 through the slot and the positioning ring 111. Then, the first gripping suction cup on the output shaft of the first gripping cylinder 422 releases the fan impeller 8.

[0070] The reciprocating mechanism 4 drives the reciprocating slide plate 42 to move toward the feeding mechanism 2, so that the gripping cylinder 422 located in the middle of the reciprocating slide plate 42 moves to above the fan impeller 8 after the oil seal pre-pressing is completed. After the output shaft of the middle gripping cylinder 422 pushes the first gripping suction cup to descend and adsorb the fan impeller 8, the output shaft of the middle gripping cylinder 422 pulls the first gripping suction cup to rise and reset.

[0071] The transfer component 65 takes out the magnetic ring 81 from the second hopper 6 and places it on one of the carriers 123 of the first rotary table 12. The first rotary table 12 drives the rotating plate 122 to rotate 180°, so that the transfer component 65 can take out the magnetic ring 81 from the second hopper 6 and place it on the other carrier 123 of the first rotary table 12. This allows the transfer component 65 to simultaneously place another magnetic ring 81 while the fan impeller 8 is pre-loaded with the magnetic ring 81, realizing the alternating feeding of the two carriers 123 of the first rotary table 12 and improving the working efficiency of the transfer component 65.

[0072] The reciprocating mechanism 4 drives the reciprocating slide plate 42 to move toward the unloading mechanism 3. The middle gripping cylinder 422 transfers the fan impeller 8 to the top of the magnetic ring 81. After the fan impeller 8 is pre-fitted into the outside of the magnetic ring 81, the first gripping suction cup on the output shaft of the middle gripping cylinder 422 releases the fan impeller 8.

[0073] The reciprocating mechanism 4 drives the reciprocating slide plate 42 to move toward the feeding mechanism 2, so that the gripping cylinder 422 located at the tail of the reciprocating slide plate 42 moves to the top of the fan impeller 8 after the magnetic ring 81 has been pre-fitted. After the output shaft of the tail gripping cylinder 422 pushes the first gripping suction cup to descend and adsorb the fan impeller 8, the output shaft of the tail gripping cylinder 422 pulls the first gripping suction cup to rise and reset. The tail gripping cylinder 422 transfers the fan impeller 8 to one of the carriers 123 of the second rotary table 13, and the oil seal on the fan impeller 8 is inserted into the hole.

[0074] The second rotary table 13 drives the rotary plate 122 to rotate 180°, so that one of the carriers 123 of the second rotary table 13 moves to the underside of the pressing block 712. The pressing block 712 of the pressing mechanism presses the fan impeller 8 placed on one of the carriers 123 of the second rotary table 13, pressing the oil seal and magnetic ring 81 into the fan impeller 8. At the same time, the tail gripping cylinder 422 can put the next fan impeller 8 to be pressed into the other carrier 123 of the second rotary table 13 that is not in use. This realizes that the two carriers 123 of the second rotary table 13 alternately unload material first, and then simultaneously load and press, thereby improving the working efficiency of the pressing mechanism.

[0075] After the impeller 8 is pressed, the second rotary table 13 drives the rotary plate 122 to rotate another 180°. The feeding screw device 31 drives the feeding cylinder 312 to slide towards the feeding mechanism 2 through the feeding slide plate 311, so that the feeding cylinder 312 is close to the top of the second rotary table 13. After the output shaft of the feeding cylinder 312 pushes the second gripping suction cup to descend and adsorb the impeller 8, the output shaft of the feeding cylinder 312 pulls the second gripping suction cup to rise and reset. The feeding screw device 31 drives the feeding cylinder 312 to slide away from the feeding mechanism 2 through the feeding slide plate 311, so as to carry the pressed impeller 8 away from the equipment to complete the feeding.

[0076] The reciprocating mechanism 4, the three gripping cylinders 422 and the unloading mechanism 3 work together to reciprocate and transfer multiple fan impellers 8 one by one to the loading mechanism 2, the positioning ring 111, the first rotating table 12 and the second rotating table 13, thereby realizing the automated pressing of oil seals and magnetic rings 81.

[0077] This utility model provides a device for assembling a fan. The feeding mechanism conveys the fan impeller toward the positioning seat. The reciprocating slide slides back and forth toward the feeding mechanism or the unloading mechanism under the drive of the reciprocating mechanism, so that the gripping cylinder located at the head of the reciprocating slide transfers the fan impeller to the positioning ring through the first gripping suction cup. After the assembly component takes out the oil seal from the first material bin and pre-presses it into the fan impeller through the positioning ring, the first gripping suction cup of the head gripping cylinder releases the fan impeller.

[0078] The transfer assembly extracts the magnetic ring from the second hopper and places it into one of the empty carriers on the second rotary table. The first rotary table drives the rotating plate to rotate 180°, allowing the transfer assembly to place the magnetic ring into another empty carrier on the second rotary table, thus realizing the alternating feeding of the two carriers on the first rotary table. The gripping cylinder located in the middle of the reciprocating slide transfers the fan impeller with the oil seal pre-pressed into place above the magnetic ring. After the fan impeller is pre-fitted into the outside of the magnetic ring, the first gripping suction cup of the middle gripping cylinder releases the fan impeller.

[0079] The gripping cylinder at the tail of the reciprocating slide transfers the pre-installed impeller with oil seals and magnetic rings to the empty carrier on the second rotary table. Then, the first gripping suction cup of the tail gripping cylinder releases the impeller, and the second rotary table drives the rotating plate to rotate 180°, allowing the pressing mechanism to completely press the oil seals and magnetic rings into the impeller. The second rotary table then drives the rotating plate to rotate 180° again, allowing the unloading mechanism to remove the pressed impeller and free up the empty carrier. This achieves alternating unloading and simultaneous loading and pressing of the two carriers on the second rotary table. By automating the placement of oil seals and magnetic rings into the impeller and performing pressing, assembly efficiency is improved.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
