Description

Technical Field

[0001] This utility model relates to the field of fan assembly machines, and in particular to a two-section annular track fan assembly machine. Background Technology

[0002] In fan assembly, FDP bearings or ordinary bearings are used with retaining rings to install fan blades. Some retaining rings are installed below the bearing, while others are installed above it. In the case where the retaining ring is installed above the bearing (the retaining ring is installed inside the upper port of the fan housing tube), the bearing needs to be fitted onto the tube and the upper port of the tube needs to be sealed. For this situation, the assembly machine needs to be divided into two sections to accommodate the bearing being assembled in the later stage. Furthermore, since the FDP bearings need to be oriented correctly before they can be placed in the corresponding workstation for assembly, traditionally, FDP bearings are manually loaded, resulting in low efficiency, low positioning accuracy, high labor intensity for workers, and high assembly costs.

In this embodiment, the first sector frame clamping drive device 941 is configured as a finger clamping cylinder.

[0071] By adopting the above technical solution, the fan frame is placed on the fan frame conveyor line 5 for conveying and feeding, and the fan blades are placed on the fan blade conveyor line 6 for conveying. When the fan frame is conveyed by the fan frame conveyor line 5 to a position close to the fan frame assembly mechanism 9, the fan frame lateral movement component 92 and the first fan frame longitudinal movement component 93 in the fan frame assembly mechanism 9 cooperate to drive the first fan frame clamping component 94 and the second fan frame clamping component 95 to work simultaneously. When the first fan frame clamping component 94 is in contact with the fan frame lateral movement component 92 and the first fan frame longitudinal movement component 93... Driven by the combined action of the first fan frame conveyor 93 and the second fan frame clamping component 95, the second fan frame clamping component 95 simultaneously clamps the previously positioned fan frame from the fan frame transfer positioning fixture 91 and places it onto the corresponding fan frame conveying fixture on the first circular track conveyor 7. This achieves fully automatic continuous feeding of fan frames, giving it the advantages of high feeding efficiency, high feeding accuracy, and good feeding effect.

In this embodiment, the oil injection valve lifting drive device 101 is configured as a cylinder.

[0074] By adopting the above technical solution, when the fan frame is conveyed into the working position of the first oiling component 10 by the first circular track conveyor line 7, the oiling valve lifting drive device 101 drives the first oiling valve 105 to descend into the middle tube of the fan frame to oil (apply lubricating oil) to the middle tube of the fan frame. This achieves fully automated oiling of the middle tube of the fan frame and has the advantages of precise oiling, high oiling efficiency and good oiling effect.

Two correction clamp arms 1132 are mounted on the output end of the correction clamp arm opening and closing drive device 1131, and correction grooves 1133 are provided on the correction clamp arms 1132.

[0076] By adopting the above technical solution, the first electrostatic fan 112 of the graphite sheet assembly mechanism 11 blows air onto the graphite sheet feeding vibratory plate 111 to remove static electricity from the graphite sheets. The graphite sheet lateral movement component 115 and the graphite sheet longitudinal movement component 116 of the graphite sheet assembly mechanism 11 cooperate to drive the graphite sheet suction nozzle 114 to pick up the graphite sheets from the graphite sheet feeding vibratory plate 111 and convey them to the pad correction component 113. The correction clamp arm opening and closing drive device 1131 drives the two correction clamp arms 1132 to close. The correction grooves 1133 of the two correction clamp arms 1132 limit and correct the graphite sheets. After the graphite sheets are positioned and corrected, when the fan frame... When the graphite sheet is conveyed into the workstation of the graphite sheet assembly mechanism 11 by the first annular track conveyor line 7, the graphite sheet suction nozzle 114 picks up the graphite sheet after positioning and correction and places it into the corresponding central tube of the fan frame on the first annular track conveyor line 7 to complete the graphite sheet assembly. The bottom of the graphite sheet is adhered to the bottom of the central tube of the fan frame by lubricating oil to prevent the graphite sheet from being carried out of the central tube by the graphite sheet assembly mechanism 11, which would cause assembly failure. The installation of the graphite sheet can prevent the end (bottom) of the central shaft of the fan blade from wearing down the bottom of the central tube of the fan frame. It realizes fully automatic assembly of graphite sheets for the fan frame and has the advantages of high assembly efficiency and good assembly effect. In this embodiment, the correction clamping arm opening and closing drive device 1131 is set as a finger clamping cylinder, but it is not a limitation.

[0077] Reference Figure 6As shown, the graphite sheet detection mechanism 12 includes a graphite sheet detection lifting drive device 121, a second guide rod connecting plate 122, a second linear guide rod 123, a first photoelectric sensor 124, a second photoelectric sensor 125, a first sensing plate 126, a telescopic rod 127, and a graphite sheet detection fixture 128.

The first sensing plate 126 is mounted on the top of the telescopic rod 127, and the graphite sheet detection fixture 128 is mounted on the bottom of the telescopic rod 127.

[0078] By adopting the above technical solution, when the fan frame is conveyed into the workstation of the graphite sheet inspection mechanism 12 by the first circular track conveyor line 7, the graphite sheet inspection mechanism 12 is used to install and inspect the graphite sheets inside the central tube of the fan frame. The graphite sheet inspection lifting drive device 121 drives the telescopic rod 127 and the graphite sheet inspection fixture 128 installed on its lower end to descend together to the upper surface of the graphite sheet inside the central tube. The descending graphite sheet inspection fixture 128 presses the graphite sheet. Since the telescopic rod 127 is longitudinally slidably installed on the front end of the second guide rod connecting plate 122, when the graphite sheet is pressed, the telescopic rod 127 slides upward at the front end of the second guide rod connecting plate 122. Since the first sensing plate 126 is installed on the top of the telescopic rod 127 and moves with the telescopic rod 127 on the second guide rod connecting plate 122... Sliding upwards away from the second guide rod connecting plate 122, when the first photoelectric sensor 124 and the second photoelectric sensor 125 simultaneously do not detect the first sensing piece 126, it indicates that no graphite sheet is installed in the middle tube; when the first photoelectric sensor 124 detects the first sensing piece 126, it indicates that the required graphite sheet is correctly installed in the middle tube; when the first photoelectric sensor 124 and the second photoelectric sensor 125 simultaneously detect the first sensing piece 126, it indicates that more than one graphite sheet is installed (i.e., more than one graphite sheet is installed). The structural design of the graphite sheet detection mechanism 12 ensures whether the required number of graphite sheets are correctly installed in the middle tube and whether the graphite sheets are installed in place. It achieves automatic detection of graphite sheets while improving assembly accuracy. In this embodiment, the graphite sheet detection lifting drive device 121 is set as a cylinder.

In this embodiment, the buckle clamping drive device 1331 is configured as a finger-clamping cylinder.

[0080] By adopting the above technical solution, the first buckle assembly mechanism 13 is used to assemble buckles inside the central tube. The second electrostatic fan 132 blows air onto the first buckle feeding vibratory plate 131 to remove static electricity from the buckles. The buckle clamping drive device 1331 of the buckle clamping assembly 133 drives the two buckle clamping arms 1332 to close and clamp the buckles. When the fan frame is conveyed into the station of the first buckle assembly mechanism 13 by the first annular track conveyor line 7, the first buckle lateral movement assembly 134 and the first buckle longitudinal movement assembly 135 cooperate to drive the buckle clamping assembly 133 to clamp the buckle from the first buckle feeding vibratory plate 131 and place it into the central tube of the corresponding fan frame on the first annular track conveyor line 7. This buckle is located on top of the graphite sheet and clamps the slot at the lower end of the central shaft of the fan blade to prevent the fan blade from detaching from the central tube. The structural design of the first buckle assembly mechanism 13 enables the buckle to automatically complete the adaptation and installation with the slot at the lower end of the central shaft of the fan blade.

[0081] When the fan frame is conveyed into the station of the buckle detection mechanism 14 by the first circular track conveyor line 7, the structure and working principle of the buckle detection mechanism 14 are the same as those of the graphite sheet detection mechanism 12. The design of the buckle detection mechanism 14 ensures that the required number of buckles are correctly installed in the middle tube and ensures that the buckles are installed in place.

One end of the FDP bearing upper push plate 1533 and one end of the FDP bearing lower push plate 1534 are integrally formed and mounted on the output end of the push plate translation drive device 1536. The push plate translation drive device 1536 pushes the FDP bearing upper push plate 1533 and the FDP bearing lower push plate 1534 to slide back and forth on the first push rail 1532. The upper end of the second FDP bearing feeding conduit 1535 is connected to the first FDP bearing feeding conduit 1515 through the conduit support 1516.

[0084] By adopting the above technical solution, the FDP bearing loading and assembly mechanism 15 is used to assemble FDP bearings in the center tube. When the fan frame is conveyed into the work position of the FDP bearing loading and assembly mechanism 15 by the first annular track conveyor line 7, the storage tank lifting drive device 1514 of the FDP bearing loading mechanism 151 drives the storage tank mounting plate 1513 to slide up and down on the guide rod of the guide rod bracket 1512, thereby driving the FDP bearing storage tank 1511 to lift up and down to shake the FDP bearing inside, so that the FDP bearing is conveyed to the FDP bearing rotary feeding mechanism 153 along the first FDP bearing loading guide tube 1515 and the second FDP bearing loading guide tube 1535. The pusher plate translation drive device 1536 pushes the upper pusher plate 1533 and the lower pusher plate 1534 of the FDP bearing to slide back and forth on the first pusher rail 1532. This sets the second FDP bearing loading guide 1535 to align with the first FDP bearing receiving hole 15303, allowing the FDP bearing to fall into the first FDP bearing receiving hole 15303 via the second FDP bearing loading guide 1535. It then aligns the first FDP bearing receiving hole 15303 with the second FDP bearing receiving hole 15307, enabling the FDP bearing to fall into the second FDP bearing receiving hole 15307. The FDP bearing rotation drive device 1539 drives the FDP bearing rotation shaft 15306 to rotate 180 degrees to rotate the FDP bearing 180 degrees. This also rotates the second FDP bearing receiving hole 15307. 5307 is configured to mate with the third FDP bearing receiving hole 15308, allowing the FDP bearing to fall into the third FDP bearing receiving hole 15308. The FDP bearing lifting drive device 1530 raises the FDP bearing lifting rod 15301, thereby lifting the FDP bearing to supply the FDP bearing to the FDP bearing assembly mechanism 152. The structural design of the FDP bearing feeding and assembly mechanism 15 enables fully automatic feeding, flipping, and feeding of FDP bearings. It has the advantages of high feeding efficiency and high feeding positioning accuracy. It eliminates the need for manual feeding of FDP bearings, thereby reducing labor costs for enterprises and reducing production and processing costs. It also solves the problems of low work efficiency, poor positioning accuracy, and high production and processing costs caused by the traditional method of manually feeding FDP bearings.

The bottom edge of the press pin 1623 is provided with suction holes 1625 at equal intervals.

[0090] By adopting the above technical solution, the bearing pressing mechanism 16 assembles ordinary bearings (hereinafter referred to as bearings) in the center tube. The bearing feeding vibratory plate 160 feeds and conveys the bearings, and the bearings fall into the bearing push plate 1632. The bearing push plate transverse drive device 1635 pushes the bearing push plate 1632 to move horizontally to perform bearing misalignment transmission. When the fan frame enters the work position of the bearing pressing mechanism 16 along the first annular track conveyor line 7, the bearing longitudinal moving component 161 drives the bearing pressing pin 162 to press the bearing in the bearing push plate 1632 into the center tube of the corresponding fan frame on the first annular track conveyor line 7 to complete the assembly of the ordinary bearing in the fan frame.

[0093] By adopting the above technical solution, the third electrostatic fan 172 blows air to remove static electricity from the buckles installed in the second buckle feeding vibratory plate 171. The second buckle assembly mechanism 17 can assemble buckles that fit the slots at the upper or lower ends of the central shaft of the fan blades according to different assembly requirements. When the fan frame is conveyed into the station of the second buckle assembly mechanism 17 by the first annular track conveyor line 7, the second buckle lateral movement component 175 and the second buckle longitudinal movement component 174 cooperate to drive the buckle insertion component 173 to move downward to insert the buckle from the second buckle feeding vibratory plate 171 and install it into the corresponding fan frame central tube on the first annular track conveyor line 7. When the positioning pin extension drive device of the buckle insertion component 173... When the buckle positioning pin 1736 extends out of the buckle release seat 1732, it can retrieve the buckle from the second buckle feeding vibratory plate 171. When the buckle needs to be placed, the positioning pin extension drive device 1731 drives the buckle positioning pin 1736 to retract into the buckle release seat 1732. The buckle is blocked by the buckle release seat 1732 and falls off the buckle positioning pin 1736. At the same time, the counterweight pin connecting seat 1734 uses its own weight to push the buckle off the buckle positioning pin 1736 through the buckle counterweight pin 1735, so that the buckle falls into the middle tube of the corresponding fan frame on the first circular track conveyor line 7, thereby realizing the automatic installation of the buckle on the fan frame.

[0104] By adopting the above technical solution, the second semi-finished product lateral movement component 222 and the second semi-finished product longitudinal movement component 223 of the semi-finished product transfer mechanism 22 cooperate to drive the second semi-finished product clamping component 224 to automatically clamp the semi-finished product fan from the semi-finished product conveyor line 29 and place it on the corresponding fan frame conveying fixture on the second annular track conveyor line 8.

The second oiling valve 233 is connected to the stator press-fit fixture mounting plate 234 through the second oiling valve mounting plate 235.

[0106] By adopting the above technical solution, the stator pressing and oiling mechanism 23 is used to press the stator placed on the corresponding sector frame conveying fixture on the second annular track conveyor line 8, and to oil the central tube of the sector frame after stator assembly is completed, to ensure that the bearing in the central tube has sufficient lubricating oil. When the sector frame is conveyed by the second annular track conveyor line 8 into the station of the stator pressing and oiling mechanism 23, the longitudinal moving component 231 of the stator pressing fixture drives the stator pressing fixture 232 to descend so as to press the stator on the corresponding sector frame conveying fixture on the second annular track conveyor line 8 onto the sector frame. The stator is firmly adhered to the sector frame with AB glue. At the same time, the longitudinal moving component 231 of the stator pressing fixture drives the second oiling valve 233 to descend so as to oil the sector frame at the next station. The structural design of the stator pressing and oiling mechanism 23 realizes that while pressing the stator on the current sector frame, it can also oil the next sector frame, which can greatly improve the overall production efficiency.

[0107] Reference Figure 23 As shown, the fan blade fastening mechanism 24 includes a fan blade positioning fixture 241 and a fan blade lateral movement component 243, etc. The fan blade positioning fixture 241 is mounted on the second platform 2 through the fan blade positioning support 242. The fan blade lateral movement component 243 is mounted on the second mounting bracket 4. The moving part of the fan blade lateral movement component 243 is longitudinally mounted with a fan blade longitudinal movement component 244. The lower end of the fan blade longitudinal movement component 244 is mounted with a first fan blade suction nozzle mounting plate 245. One end of the first fan blade suction nozzle mounting plate 245 is mounted with a first fan blade suction nozzle 246. The other end of the first fan blade suction nozzle mounting plate 245 is mounted with a fan blade pressure head 247. A second fan blade suction nozzle 248 is provided inside the fan blade pressure head 247.

[0108] By adopting the above technical solution, the fan blade fastening mechanism 24 clamps the fan blade from the fan blade conveyor line 6, positions it, and places it on the corresponding fan frame on the second annular track conveyor line 8 for fan blade fastening. The fan blade lateral movement component 243 and the fan blade longitudinal movement component 244 cooperate to drive the first fan blade suction nozzle 246 to pick up the fan blade from the fan blade conveyor line 6 and place it on the fan blade positioning fixture 241. At the same time, the fan blade lateral movement component 243 and the fan blade longitudinal movement component 244 cooperate to drive the second fan blade suction nozzle 248 to pick up the previously positioned fan blade from the fan blade positioning fixture 241 and place it in the bearing inside the corresponding fan frame on the second annular track conveyor line 8. The fan blade pressure head 247 presses the central shaft of the fan blade into the bearing to complete the fan frame assembly of the fan blade. This achieves fully automatic feeding, positioning, and fastening of the fan blade into the fan frame, and has the advantages of high installation efficiency, high installation accuracy, and good installation effect.

[0109] Reference Figure 24 As shown, the fan blade detection mechanism 25 includes a fan blade suction nozzle longitudinal moving assembly 251 mounted on the second mounting bracket 4. A second fan blade suction nozzle mounting plate 252 is mounted on the lower end of the fan blade suction nozzle longitudinal moving assembly 251. A sensor support 253 is mounted on the upper part of the second fan blade suction nozzle mounting plate 252. A third fan blade suction nozzle 254 is arranged below the second fan blade suction nozzle mounting plate 252. A pressure sensor 255 is connected to the upper end of the third fan blade suction nozzle 254. The pressure sensor 255 is mounted on the sensor support 253. A first fan blade pressing assembly 256 and a second fan blade pressing assembly 257 are respectively arranged on the two ends of the second fan blade suction nozzle mounting plate 252. The first fan blade pressing assembly 256 and the second fan blade pressing assembly 257 each include a fan blade pressing telescopic rod 258. A fan blade pressing block 259 is mounted on the lower end of the fan blade pressing telescopic rod 258.

[0110] By adopting the above technical solution, the fan blade detection mechanism 25 performs a pull-out test on the fan blade to ensure that the retaining ring securely clamps the slot of the fan blade's central shaft. Since the third fan blade suction nozzle 254 is connected to an external vacuum system, when the fan frame is conveyed into the station of the fan blade detection mechanism 25 along the second annular track conveyor line 8, the longitudinal movement component 251 of the fan blade suction nozzle drives the first fan blade pressing component 256, the third fan blade suction nozzle 254, and the second fan blade pressing component 257 to descend onto the corresponding fan blade and press the third fan blade suction nozzle 254 to clamp the fan blade. The fan blade pressing blocks 259 in the first fan blade pressing component 256 and the second fan blade pressing component 257 are both subjected to the pressure of the fan blade, causing the fan blade pressing telescopic rod 258 to shorten. The first fan blade pressing component 256 and the second fan blade pressing component 257 press the third fan blade... The blade suction nozzle 254 clamps the fan blade for cushioning. When the longitudinal movement component 251 of the fan blade suction nozzle drives the third fan blade suction nozzle 254 to rise and pull the fan blade to test whether the central shaft of the fan blade is firmly engaged with the retaining ring. The pressure sensor 255 automatically senses the pressure of the third fan blade suction nozzle 254 pulling the fan blade. When the value displayed by the pressure sensor 255 when the fan blade is pulled out is less than the set value, it indicates that the fan blade is not properly fastened. If the value displayed by the pressure sensor 255 is greater than the set value and the fan blade is not pulled out, it indicates that the fan blade is properly fastened to the bearing and is firmly installed. This ensures that the fan blade is correctly installed on the fan frame. The structural design of the fan blade detection mechanism 25 realizes automatic testing of the fan blade assembly and has the advantages of high testing efficiency and good testing effect.

The third fan frame clamping component 264 includes a second fan frame clamping drive device 265, and two second fan frame clamping arms 266 are mounted on the output end of the second fan frame clamping drive device 265.

[0112] By adopting the above technical solution, the fan frame flipping mechanism 26 flips the fan frame with the fan blades fastened by 180 degrees, preparing for the subsequent assembly of magnets at the bottom of the fan frame. When the fan frame is conveyed into the station of the fan frame flipping mechanism 26 by the second circular track conveyor line 8, the second fan frame longitudinal moving component 261 drives the third fan frame clamping component 264 to rise and fall, thereby driving the fan frame with the fan blades fastened to rise and fall. The fan frame flipping drive device 263 drives the third fan frame clamping component 264 to flip, thereby flipping the fan frame with the fan blades fastened. The second fan frame clamping drive device 265 drives the two second fan frame clamping arms 266 to close, thereby clamping the fan frame with the fan blades fastened, so that it can automatically flip the fan frame with the fan blades fastened, and has the advantage of high flipping efficiency.

The magnet limiting plate 2725 is mounted on the end of the third push rail 2721 away from the magnet push plate lateral movement drive device 2724.

[0115] By adopting the above technical solution, the magnet assembly mechanism 27 assembles magnets at the bottom of the fan frame. The magnets are conveyed through the magnet guide tube 273 to the magnet push plate 2722 of the magnet lateral movement component 272. The magnet push plate lateral movement drive device 2724 pushes the magnet push plate 2722 to move laterally, realizing the misalignment and material distribution of the magnets and moving them below the magnet pin 274. When the fan frame is conveyed into the station of the magnet assembly mechanism 27 by the second annular track conveyor line 8, the magnet longitudinal movement component 271 drives the magnet pin 274 to press the magnets downward onto the flipped fan frame. The magnets use magnetic force to hold the central axis of the fan blades to prevent the fan blades from detaching from the fan frame. This achieves fully automatic assembly of magnets for the fan frame and has the advantages of high assembly efficiency and good assembly effect. After the fan frame is assembled with magnets, it becomes a finished fan. In this embodiment, the magnet push plate lateral movement drive device 2724 is set as a cylinder.
