[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-2 A fully automatic assembly line for ceiling fan motors includes a frame 1, a transmission line 2, a mobile positioning fixture 3, a front cover automatic feeding station 4, a bearing automatic feeding station 5, a rotor automatic feeding station 6, a stator feeding station 7, a rear cover automatic feeding station 8, a front screw locking station 9, a flipping station 10 and a back screw locking station 20. The transmission line 2 is arranged on the frame 1. The front cover automatic feeding station 4, the bearing automatic feeding station 5, the rotor automatic feeding station 6, the stator feeding station 7, the rear cover automatic feeding station 8, the front screw locking station 9, the flipping station 10 and the back screw locking station 20 are sequentially arranged along the conveying direction of the transmission line 2 and correspond to the mobile positioning fixture 3. There are multiple mobile positioning fixtures 3 and they are arranged on the transmission line 2. By providing a plurality of movable positioning jigs 3, it can be ensured that each station has a movable positioning jig 3 during assembly, so as to facilitate movement to the next station on the transmission line 2 after assembly.

[0027] A fully automatic assembly line for ceiling fan motors also includes a bearing automatic pressing station 30, a rotor automatic pressing station 40, a stator automatic pressing station 50 and a rear cover automatic pressing station 60, a front cover automatic feeding station 4, a bearing automatic feeding station 5, a bearing automatic pressing station 30, a rotor automatic feeding station 6, a rotor automatic pressing station 40, a stator feeding station 7, a stator automatic pressing station 50, a rear cover automatic feeding station 8, a rear cover automatic pressing station 60, a front screw locking station 9, a flipping station 10 and a rear screw locking station 20 are arranged in sequence along the conveying direction of a transmission line 2.

[0028] By arranging the above-mentioned processes in sequence, when assembling the ceiling fan motor, it is first placed and sequentially passes through the front cover - bearing assembly - bearing pressing - rotor assembly - rotor pressing - stator assembly - stator pressing - rear cover assembly - rear cover pressing - front side screw locking - back side screw locking, thereby realizing the overall assembly of the ceiling fan motor, greatly saving labor and improving assembly efficiency.

[0029] like Figure 2 and Figure 3As shown, the transmission line 2 includes a transmission motor 21, a conveying chain 22, a first gear 23, a second gear 24 and an annular slide rail 25. The transmission motor 21, the annular slide rail 25, the first gear 23 and the second gear 24 are all arranged on the frame 1. The first gear 23 is connected to the output shaft of the transmission motor 21. The conveying chain 22 is sleeved on the first gear 23 and the second gear 24. The annular slide rail 25 is located on the outside of the conveying chain 22. The front cover automatic feeding station 4, the bearing automatic feeding station 5, the bearing automatic pressing station 30, the rotor automatic feeding station 6, the rotor automatic pressing station 40, the stator feeding station 7, the stator automatic pressing station 50, the rear cover automatic feeding station 8, the rear cover automatic pressing station 60, the front screw locking station 9, the flipping station 10 and the reverse screw locking station 20 are all arranged corresponding to the conveying chain 22 and the annular slide rail 25, and the conveying chain 22 is annular.

[0030] Therefore, the first gear 23 can be driven to rotate through the transmission motor 21, and the conveying chain 22 can be driven to transmit through the first gear 23, thereby driving each mobile positioning fixture 3 to move; since the conveying chain 22 is ring-shaped, it is convenient for the mobile positioning fixture 3 to start moving at the initial position, and after completing a circle of assembly, it returns to the initial position, without the need for manual re-loading of the mobile positioning fixture 3.

[0031] In order to facilitate the conveying chain 22 to drive the mobile positioning fixture 3 to move, the bottom end of the mobile positioning fixture 3 is fixed on the conveying chain 22; the annular slide rail 25 is located on the outer periphery of the conveying chain 22, and is also arranged in a ring shape. A slider is provided at the bottom end of the mobile positioning fixture 3, and the slider cooperates with the annular slide rail 25. The annular slide rail 25 can limit and guide the mobile positioning fixture 3, thereby ensuring that the mobile positioning fixture 3 can move smoothly under the drive of the conveying chain 22.

[0032] Among them, the mobile positioning fixture 3 includes a support frame 31, a support plate 32 and a positioning rod 33. The support frame 31 is clamped and fixed with the conveying chain 22 and cooperates with the annular slide rail 25; the support plate 32 is fixed at the top of the support frame 31, and a groove is provided on the support plate 32, and its shape matches the front cover of the ceiling fan motor; the positioning rod 33 is fixed on the upper end surface of the support plate 32. By providing the positioning rod 33, it can pass through the through hole on the front cover of the ceiling fan motor, so that the position of the front cover on the support plate 32 can be determined, which is convenient for each process to quickly determine the assembly position, improve the assembly efficiency, and ensure the assembly accuracy.

[0033] like Figure 2 and Figure 4As shown, the automatic front cover loading station 4 includes a front cover loading rack 41, a front cover lifting cylinder 42, a front cover forward and backward moving cylinder 43, a suction cup rack 44 and a front cover forward and backward moving rack 45. The front cover loading rack 41 is fixed on the frame 1, the front cover forward and backward moving cylinder 43 is fixed on the front cover loading rack 41, the front cover forward and backward moving rack 45 is connected to the piston rod of the front cover forward and backward moving cylinder 43, the front cover lifting cylinder 42 is fixed on the front cover forward and backward moving rack 45, the suction cup rack 44 is connected to the piston rod of the front cover lifting cylinder 42, and the suction cup rack 44 is arranged corresponding to the mobile positioning fixture 3. A plurality of suction cup heads 46 are installed on the suction cup rack 44, and each suction cup head 46 is provided with a plurality of suction nozzles, through which the front cover of the ceiling fan motor can be sucked and moved and transported. The front cover forward and backward moving cylinder 43 is arranged horizontally, and the front cover lifting cylinder 42 is arranged vertically; the front cover loading rack 41 is located on the outside of the annular slide rail 25.

[0034] When the mobile positioning fixture 3 at the front cover automatic feeding station 4 is in an empty state, the front cover is placed on the mobile positioning fixture 3 through the front cover automatic feeding station 4. Specifically, the piston rod of the front cover lifting cylinder 42 extends downward, pushing the suction cup frame 44 to move downward, and the suction nozzle on the suction cup frame 44 sucks the front cover below tightly; then, the piston rod of the front cover lifting cylinder 42 is pulled back; the piston rod of the front cover forward and backward moving cylinder 43 extends forward, pushing the front cover forward and backward moving frame 45 to move forward, and when the front cover on the suction cup frame 44 moves forward to the top of the corresponding mobile positioning fixture 3, the front cover lifting cylinder 42 extends the piston rod downward, so that the corresponding front cover is located on the support plate 32, and the corresponding suction nozzle is released, so that the front cover is placed on the mobile positioning fixture 3, and the automatic feeding of the front cover is completed. Subsequently, each cylinder on the front cover automatic feeding station 4 is reset to facilitate the next front cover feeding. When the front cover of the ceiling fan motor is automatically loaded at the front cover automatic loading station 4 , the movable positioning fixture 3 is moved to the bearing automatic loading station 5 along with the conveying chain 22 .

[0035] like Figure 2 and Figure 5 As shown, the automatic bearing loading station 5 includes a bearing loading rack 51, a bearing lifting cylinder 52, a bearing forward and backward moving cylinder 53, a bearing grabbing rack 54, a bearing forward and backward moving rack 55, a bearing feeding barrel 56 and a bearing conveyor belt 57. The bearing loading rack 51 is fixed on the frame 1, the bearing feeding barrel 56 is vertically arranged and located above the bearing conveyor belt 57, the bearing conveyor belt 57 is arranged corresponding to the bearing grabbing rack 54, the bearing forward and backward moving cylinder 53 is fixed on the bearing loading rack 51, the bearing forward and backward moving rack 55 is connected to the piston rod of the bearing forward and backward moving cylinder 53, the bearing lifting cylinder 52 is arranged on the bearing forward and backward moving rack 55, the bearing grabbing rack 54 is connected to the bearing lifting cylinder 52, and is arranged corresponding to the mobile positioning fixture 3.

[0036] The automatic bearing loading station 5 also includes a bearing conveying motor 58, and a bearing conveying belt 57 (blocked in the figure, not shown) is sleeved on the output shaft of the bearing conveying motor 58, and the bearing conveying belt 57 is driven by the bearing conveying motor 58; wherein, the motor-driven conveying belt transmission is the same as the motor-driven conveying belt transmission method commonly used in the prior art. The conveying direction of the bearing conveying belt 57 is consistent with the moving direction of the bearing forward and backward moving cylinder 53, both of which are horizontal directions.

[0037] In order to facilitate the automatic feeding of bearings, multiple bearing feeding cylinders 56 are arranged side by side. The inner diameter of each bearing feeding cylinder 56 matches the outer diameter of the bearing. Multiple bearings can be stacked in each bearing feeding cylinder 56. The bottom of the bearing feeding cylinder 56 is a through structure. A bearing feeding rack 59 is fixed on one side of the bearing loading rack 51. The bearing feeding cylinder 56 is fixed on the bearing feeding rack 59. A push cylinder 591 and a push plate 592 are installed below the bearing feeding rack 59. The push plate 592 is connected to the piston rod of the push cylinder 591. The push plate 592 is located below the bearing feeding cylinder 56 and on one side of the bearing conveyor belt 57. A slide rail 593 is provided on the bearing feeding rack 59. The slide rail 593 is located below the bearing feeding cylinder 56. The push plate 592 cooperates with the slide rail 593. The distance between the slide rail 593 and the bottom end of the bearing supply cylinder 56 is greater than the height of a single bearing and less than the height of two bearings, thereby facilitating a layer of bearings at the bottom of the bearing supply cylinder 56 to fall between the slide rail 593 and the bearing supply cylinder 56.

[0038] When the mobile positioning fixture 3 with the front cover of the ceiling fan motor is moved to the automatic bearing loading station 5, the automatic bearing loading station 5 moves the bearing to be assembled on the front cover of the ceiling fan motor. Specifically, the pushing cylinder 591 drives the pushing plate 592 to move toward the side of the bearing conveyor belt 57, and the pushing plate 592 pushes the lowest layer of bearings at the bottom of the bearing supply cylinder 56 onto the bearing conveyor belt 57, and then the bearing is transported to the bottom of the bearing grabbing frame 54 through the bearing conveyor belt 57.

[0039] At this time, the bearing lifting cylinder 52 drives the bearing grabbing frame 54 to move downward, so that the bearing grabbing frame 54 can grab the corresponding bearing on the bearing conveyor belt 57, and then the bearing lifting cylinder 52 pulls back upward; then, the piston rod of the bearing forward and backward moving cylinder 53 extends out, pushing the bearing forward and backward moving frame 55 forward, thereby driving the bearing grabbing frame 54 forward; when the bearing grabbed by the bearing grabbing frame 54 moves to the top of the motor front cover on the front side moving positioning fixture 3, the bearing lifting cylinder 52 pushes the bearing grabbing frame 54 downward to the motor front cover. When the bearing is placed, the piston rods of the bearing lifting cylinder 52 and the bearing forward and backward moving cylinder 53 retract and reset to facilitate the grabbing of the next bearing.

[0040] After the bearing is placed on the front cover of the ceiling fan motor, the corresponding movable positioning fixture 3 moves along the conveying chain 22 to the bearing automatic pressing station 30, through which the bearing automatic pressing station 30 can press the bearing into the corresponding through hole on the front cover.

[0041] After the bearing is pressed on the front cover, the corresponding positioning fixture 3 is moved to the rotor automatic feeding station 6, and the rotor is assembled to the front cover through the rotor automatic feeding station 6; then it is moved to the rotor automatic pressing station 40 to press the rotor into place.

[0042] In actual use, the structure of the rotor automatic feeding station 6 is the same as that of the front cover automatic feeding station 4, the difference being that the suction nozzle in the suction cup frame 44 is replaced by a claw, the rotor is grabbed by the claw, and placed on the motor front cover for pressing the bearing. Subsequently, the movable positioning fixture 3 with the rotor placed thereon moves to the rotor automatic pressing station 40 to press the rotor into place on the front cover.

[0043] After the rotor is pressed in place, the stator is placed on the motor front cover at the stator loading station 7. A robot can be provided on the stator loading station 7, or the stator can be placed on the motor front cover manually. When the stator is placed, the corresponding moving positioning fixture 3 is moved to the stator automatic pressing station 50 for pressing.

[0044] like Figure 2 and Figure 6 As shown, the stator automatic pressing station 50 includes a mounting frame 501, a pressing cylinder 502 and a pressing head 503. The mounting frame 501 is arranged on the frame 1 and is located above the transmission line 2. The cylinder body of the pressing cylinder 502 is fixed on the mounting frame 501. The pressing head 503 is connected to the piston rod of the pressing cylinder 502 and corresponds to the mobile positioning fixture 3. When in use, the mobile positioning fixture 3 with the stator placed thereon moves to the bottom of the pressing head 503 of the stator automatic pressing station 50. At this time, the piston rod of the pressing cylinder 502 is pushed downward, pushing the pressing head 503 to move downward, so that the pressing head 503 is pressed downward on the stator, so that the position of the stator on the front cover is pressed in place.

[0045] In actual use, the structure of the bearing automatic pressing station 30 and the structure of the rotor automatic pressing station 40 are the same as the structure of the stator automatic pressing station 50, except that the shape of the pressing head is different, and the pressing principle is the same. The size of the pressing head of the bearing automatic pressing station 30 matches the size of the bearing, and the bearing can be pressed flatly on the front cover; the size of the pressing head in the rotor automatic pressing station 40 is consistent with the outer diameter of the rotor, so that the pressing head can press the rotor down as a whole and press the rotor into place on the front cover.

[0046] When the stator is pressed in place, the corresponding movable positioning fixture 3 moves to the rear cover automatic feeding station 8, and the rear cover is automatically fed through the rear cover automatic feeding station 8, and the rear cover is matched with the front cover. Among them, the structure of the rear cover automatic feeding station 8 is the same as that of the front cover automatic feeding station 4, and the automatic feeding of the rear cover is realized.

[0047] When the rear cover is loaded, the corresponding mobile positioning fixture 3 moves to the front screw locking station 9. Among them, the front screw locking station 9 is an automatic screw locking machine, which is a prior art and its structure is not described here. Through the front screw locking station 9, the three screws on the front of the ceiling fan motor can be locked and fixed without manual operation. Subsequently, the ceiling fan motor moves to the flipping station 10 with the mobile positioning fixture 3, and the fan motor is flipped 180° through the flipping station 10.

[0048] like Figure 2 and Figure 7 As shown, the flipping station 10 includes a flipping bracket 101, a flipping lifting cylinder 102, a flipping lifting frame 103 and a flipping cylinder 104. The flipping bracket 101 is fixed on the frame 1, the flipping lifting cylinder 102 is arranged on the flipping bracket 101, the flipping lifting frame 103 is connected to the piston rod of the flipping lifting cylinder 102, the flipping cylinder 104 is arranged on the flipping lifting frame 103, and a chuck 105 is connected to the flipping cylinder 104. The chuck 105 is arranged corresponding to the mobile positioning fixture 3, that is, the chuck 105 can clamp the ceiling fan motor on the mobile positioning fixture 3.

[0049] When the flipping station 10 is working, the flipping lifting cylinder 102 pushes the flipping lifting frame 103 to move downward, so that the chuck 105 can clamp the ceiling fan motor downward; the chuck 105 can be a finger cylinder, which can easily clamp the ceiling fan cylinder. When the ceiling fan motor is clamped by the chuck 105, the flipping lifting cylinder 102 drives the flipping lifting frame 103 and the flipping cylinder 104 to move upward; after moving into place, enough space is reserved for the flipping of the ceiling fan motor. Subsequently, the flipping cylinder 104 works to make the chuck 105 flip 180°, and the chuck 105 drives the ceiling fan motor to flip 180° together; then the flipping lifting cylinder 102 moves downward again until the ceiling fan motor is placed on the movable positioning fixture 3 below; the chuck 105 releases the ceiling fan motor and moves upward to reset, which is convenient for the flipping of the next motor.

[0050] When the ceiling fan motor is flipped 180°, the upper and lower positions of the front cover and the rear cover are reversed, and the movable positioning fixture 3 moves to the reverse screw locking station 5. The structure of the reverse screw locking station 5 is the same as that of the front screw locking station 9, so that the reverse side of the ceiling fan motor can be screwed, thereby eliminating the need for manual operation, improving efficiency, and saving labor.

[0051] When the screws on the reverse side are tightened, the assembly of the entire ceiling fan motor is completed. The ceiling fan motor can be unloaded by the unloading robot and sent out through an external conveyor belt to complete the unloading.

[0052] like Figure 2 and Figure 8 As shown, a fully automatic assembly line for ceiling fan motors of the present invention also includes a front cover automatic anti-vibration pad sticking station 70, which is located outside the front cover automatic feeding station 4. The front cover automatic anti-vibration pad sticking station 70 includes a front cover conveyor belt 701, a front cover flip motor 702, a lifting cylinder 703 and a limit block 704. The front cover conveyor belt 701 is located on one side of the front cover automatic feeding station 4, and a strip groove 705 is provided on the front cover conveyor belt 701. The front cover flipping motor 702 is arranged on one side of the front cover conveyor belt 701, and a front cover clamp 706 is arranged on the output shaft of the front cover flipping motor 702. The limit block 704 is located above the front cover conveyor belt 701. The limit block 704 and the front cover automatic loading station 4 are respectively located on both sides of the front cover flipping motor 702. The front cover clamp 706 corresponds to the limit block 704, and the lifting cylinder 703 is located below the front cover conveyor belt 701, and its piston rod can pass through the strip groove 705.

[0053] The automatic feeding structure of the shockproof pad in the front cover automatic shockproof pad station 70 is the same as the structure of the existing labeling machine, which sticks the shockproof pad tightly to the outside of the front cover. Before sticking the shockproof pad, the front cover can be placed in a unified direction to facilitate the consistency of subsequent labeling and to facilitate positioning on the later moving positioning fixture 3. After the shockproof pad is stuck on the outside of the front cover, it is placed on the front cover conveyor belt 701, which is a belt conveyor. As the front cover conveyor belt 701 is conveyed, the front cover is conveyed to the limit block 704, and the limit block 704 limits the front cover to prevent the front cover from being further conveyed forward.

[0054] When the front cover is conveyed to the limit block 704, the piston rod of the lifting cylinder 703 pushes upward, and lifts the front cover near the limit block 704; then, the front cover flipping motor 702 works, driving the front cover clamp 706 to rotate to the side of the lifting cylinder 703, and clamps the front cover that is pushed upward. After the front cover is clamped, the front cover flipping motor 702 drives the front cover clamp 706 to flip 180°, so that the upper and lower sides of the front cover are flipped. After the front cover is flipped, it continues to be transported along the front cover conveyor belt 701, and is transported to the front cover automatic loading station 4, so that the suction cup frame 44 can suck and load the front cover.

[0055] By providing the strip groove 705 on the front cover conveyor belt 701, it is possible to facilitate the placement of the raised portion of the top end of the front cover on the conveyor belt, facilitate the smooth conveyance of the front cover, and play a certain guiding role for the front cover.
