Optionally, Figure 2 In the embodiment, as an example, the frame 10 is square. Obviously, according to actual needs, the frame 10 can also be other shapes known in the art, so it is not limited to the above. Figure 1 Limits shown.

[0041] Recombination Figure 2 and Fig.13 The rotary conveyor line 40 includes a rotary chain 41, a rotary driver 42 for driving the rotary chain 41 to perform horizontal rotary motion, and a plurality of support seats 43 arranged on the rotary chain 41 along the rotary direction of the rotary chain 41 and used to support the bottom cover 210 pre-installed with the stator 220. The buckle feeding mechanism 20 is adjacent to the buckle assembly mechanism 50b, the bearing feeding mechanism 30a is adjacent to the bearing assembly mechanism 50e, and the fan blade transfer mechanism 30b is adjacent to the fan blade pressing mechanism 60.

[0042] Therefore, when the support seat 43 follows the rotary chain 41 to make a rotary motion, the stator pressing mechanism 50a presses the stator 220 of the shaft sleeve structure 211 pre-coated on the bottom cover 210 on the support seat 43 to achieve the correct matching between the stator 220 and the shaft sleeve structure 211; the buckle assembly mechanism 50b clamps the buckle 230 delivered by the buckle feeding mechanism 20 to the shaft sleeve structure 211 to achieve the purpose of fixing the stator 220 and the bottom cover 210 by the buckle 230; the buckle detection mechanism 50c detects whether the shaft sleeve structure 211 is clamped with the buckle 230 to ensure the reliability of subsequent work; the first oiling mechanism 50d applies oil to the shaft sleeve structure 211; the bearing assembly mechanism 50e fixes the shaft sleeve structure 211 with the buckle 230; The bearing 240 delivered by the bearing feeding mechanism 30a is installed in the sleeve structure 211; the second oiling mechanism 50f applies oil to the bearing 240; the labeling mechanism 50g labels the bottom of the bottom cover 210; the blade pressing mechanism 60 presses the shaft 251 of the blade 250 delivered by the blade transfer mechanism 30b into the bearing 240 to obtain the fan body 200; the blade tension testing mechanism 70a performs a tension test between the blade 250 and the bottom cover 210; when the tension test fails to meet the preset requirements, the defective product unloading robot 70b unloads the unqualified fan body 200; when the tension test meets the preset requirements, the qualified fan body 200 is unloaded by the qualified product unloading robot 70c. More specifically, as follows:

[0043] Combination Figure 2 , Fig.13 and Fig.14As an example, the fan body assembly labeling machine 100 of the present invention also includes a blade loading conveyor line 70d arranged opposite to the blade pressing mechanism 60, an auxiliary labeling mechanism 90a adjacent to the labeling mechanism 50g and arranged between the labeling mechanism 50g and the rotating chain 41, a good product unloading conveyor line 90b adjacent to the good product unloading manipulator 70c, and a positioning driver 44 located below the corresponding supporting seat 43 and arranged up and down, and a circular guide rail 90d mounted on the frame 10 and arranged around the rotating chain 41. A positioning die base 80 is provided between the blade feeding conveyor line 70d and the rotary chain 41, and a positioning structure 81 for positioning the blade 250 is provided on the positioning die base 80; the blade transfer mechanism 30b spans over the positioning die base 80, the blade feeding conveyor line 70d and the rotary chain 41 to ensure that the blade transfer mechanism 30b can accurately transfer the blade 250 conveyed by the blade feeding conveyor line 70d to a position matching the bottom cover 210. The auxiliary labeling mechanism 90a is used to pick up the bottom cover 210 with the buckle 230 and the bearing 240 after being oiled by the second oiling mechanism 50f of the support seat 43 and turn it upside down, and the labeling mechanism 50g, with the assistance of the auxiliary labeling mechanism 90a, affixes the label to the bottom cover 210 with the bottom facing up. The good product unloading conveyor line 90b is located beside an outer side of the rotary chain 41 to meet the need of the good product unloading conveyor line 90b to automatically unload the fan body 200 conveyed by the good product unloading robot 70c. The support seat 43 is provided with a matching structure 431 located beside the outer side of the circular guide rail 90d, and the output end 441 of the positioning driver 44 is equipped with a positioning structure 442 for positioning and cooperating with the matching structure 431, so that before the corresponding operation, the positioning driver 44 first positions the support seat 43 with the help of the matching structure 431 and the positioning structure 442, thereby ensuring the reliability of subsequent operations. The outer wall of the circular guide rail 90d is provided with a circular groove 97 arranged around the rotary chain 41, and the support seat 43 is correspondingly equipped with a guide roller 432 embedded in the circular groove 97 and rolling along the circular groove 97. With the cooperation of the guide roller 432 and the circular groove 97, on the one hand, the support strength of the support seat 43 is increased, and on the other hand, the smoothness and stability of the support seat 43 following the rotary chain 41 in the rotary motion are improved, thereby avoiding the defects such as jamming and jumping during the rotary process. Specifically, combined with Figures 13 to 17 As an example, the guide rollers 432 on the support seat 43 are two and are arranged spaced apart from each other along the rotation direction of the rotary chain 41; obviously, according to actual needs, the guide rollers 432 on the support seat 43 can also be three or four. Fig.17The figure is limited to the figure; in addition, the matching structure 431 on the support seat 43 is located between the guide rollers 432 on the support seat 43 along the rotation direction of the rotary chain 41, so as to effectively improve the accuracy of the support seat 43 being positioned by the positioning driver 44. In addition, each support seat 43 corresponds to a positioning driver 44, and each positioning driver 44 is equipped with a positioning structure 442 on the output end 441; such a design can be positioned from various positions in the rotation direction of the rotary chain 41 to better meet the requirements of "the stator clamping mechanism 50a before clamping the stator 220, the buckle assembly mechanism 50b before assembling the buckle 230, the buckle detection mechanism 50c before detecting the buckle 230, the first oiling mechanism 50d before oiling the sleeve structure 211, and the bearing assembly mechanism 50e before assembling the bearing 240" , before the second oiling mechanism 50f assembles the bearing 240, before the labeling mechanism 50g labels the bottom of the bottom cover 210, before the fan blade pressing mechanism 60 presses the fan blade 250, before the fan blade tension testing mechanism 70a performs the tension test between the fan blade 250 and the bottom cover 210, before the defective product unloading robot 70b unloads the unqualified fan body 200, and before the good product unloading robot 70c unloads the qualified fan body 200”, the corresponding supporting seat 43 is positioned, so as to improve the working reliability of the fan twist cover assembly labeling machine 100 of the present invention. More specifically, in Fig.14 and Fig.16 As an example, the setting structure 431 is a column arranged flat, and the positioning structure 442 is a positioning groove with a notch facing upward; this design makes the engagement or separation between the positioning structure 442 and the setting structure 431 smoother and more convenient; in addition, the output end 441 of the positioning driver 44 is arranged upward to simplify the assembly relationship between the output end 441 of the positioning driver 44 and the positioning structure 442; obviously, according to actual needs, the specific structures of the setting structure 431 and the positioning structure 442 and the orientation of the output end 441 of the positioning driver 44 can also be other, so it is not used here. Fig.14 and Fig.16 Limits shown.

[0044] Combination Figures 3 to 8As an example, the buckle feeding mechanism 20 includes a closed cavity 21, a rotating driver 22 located above the closed cavity 21 and with an output shaft 221 extending downward into the closed cavity 21, a sweeping plate 23 located in the closed cavity 21, a material receiving slider 24 located below the closed cavity 21, and a switching driver 25 for driving the material receiving slider 24 to switch between at least a first position and a second position. A truncated cone 26 protruding from the closed cavity 21, a circular groove 27 arranged in a downward direction around the truncated cone 26, and a discharge hole 28 connected to the upper and lower parts of the circular groove 27 are provided on the lower end wall 211 of the closed cavity 21. A trapezoidal notch 231 is provided at the center of the lower side of the sweeping plate 23, and the truncated cone 26 is placed in the notch 231 with a clearance fit. The lower sides 232 of the sweeping plate 23 are also spaced apart from the lower end wall 2111 of the closed cavity 21 by a preset distance. See the state. Figure 8 As shown; this design effectively controls the discharge hole 28 to enter only one buckle 230 of the closed cavity 21 at a time. The reason is: when the buckle 230 from the outside enters the closed cavity 21 from the feeding port 212 above the closed cavity 21, the buckle 230 is first dispersed and guided to the outer edge position close to the lower end wall 211 by the truncated cone 26, and then the buckle 230 is swept by the sweeping plate 23, so that the buckle 230 with a layer of the circular groove 27 is flattened; and among the buckles 230 with a layer of flattened, only the buckle 230 aligned with the discharge hole 28 can enter the discharge hole 28. Specifically, combined with Figures 9 to 11 As an example, the receiving slide 24 is provided with a positioning cavity 241 with the cavity opening 2411 facing upward, and a vacuum channel 242 and an auxiliary channel 243 communicating with the positioning cavity 241; the vacuum channel 242 and the auxiliary channel 243 are respectively communicated with the positioning cavity 241 on the cavity bottom wall 2412 of the positioning cavity 241; with the help of the vacuum channel 242, the reliability of the buckle 230 being transferred from the discharge hole 28 to the positioning cavity 241 is ensured, and with the help of the auxiliary channel 243, an auxiliary blowing effect is provided when the buckle assembly mechanism 50b removes the buckle 230 on the receiving slide 24, so as to facilitate the buckle assembly mechanism 50b to take the buckle 230 from the positioning cavity 241; in addition, the positioning cavity 241 is aligned with the discharge hole 28 when the receiving slide 24 is switched to the first position, and the state is shown in 6 and Figure 7 As shown; the positioning cavity 241 is aligned with the buckle assembly mechanism 50b when the receiving slide 24 switches to the second position, and the receiving slide 24 also closes the discharge hole 28 to prevent the buckle 230 in the closed cavity 21 from falling into the outside through the discharge hole 28.

[0045] Recombination Figures 9 to 11 As an example, the vacuum channel 242 includes a main channel 2421 and a plurality of center lines surrounding the positioning cavity 241 (see Fig.10) are arranged in a separated manner, and the branch channel 2422 is connected to the positioning cavity 241 on the cavity bottom wall 2412 of the positioning cavity 241; such a design enables the vacuum channel 242 to suck the buckle 230 in the positioning cavity 241 from multiple positions, thereby improving the reliability of the buckle 230 sliding along with the material receiving slide 24. In addition, the auxiliary channel 243 is arranged obliquely relative to the center of the positioning cavity 241, so that when the buckle assembly mechanism 50b removes the buckle 230 in the positioning cavity 241, the auxiliary channel 243 provides an oblique blowing force to the buckle 230 in the positioning cavity 241, thereby making it easier for the buckle assembly mechanism 50b to remove the buckle 230 in the positioning cavity 241. In addition, the receiving slide 24 is provided with a blind hole 244 extending upward from the center of the positioning cavity 241 through the center of the cavity bottom wall 2412 of the positioning cavity 241, so as to provide more sufficient working space for the buckle assembly mechanism 50b to remove the buckle 230 in the positioning cavity 241. For example, the rotation driver 22 may be a motor but not limited thereto, and the switching driver 25 may be a cylinder but not limited thereto.

[0046] like Fig.12 As shown, as an example, the blade transfer mechanism 30b includes a linear transfer module 31, a transfer slide 32 and a slide assembly mounted on the transfer slide 32 and along the sliding direction of the transfer slide 32 (see Fig.12 The first lifting driver 33 and the second lifting driver 34 are separated from each other (indicated by the double arrows in the middle), and the output ends 331 (341) of the first lifting driver 33 and the second lifting driver 34 are each equipped with a vacuum suction head 35 located below the transfer slide 32, and the vacuum suction head 35 is arranged downward; this design allows the transfer of the fan blade 250 at the fan blade feeding conveyor line 70d to the positioning mold base 80 and the transfer of the fan blade 250 at the positioning mold base 80 to the support base 43 of the rotating chain 41 to be performed synchronously, so the coordination is better. Specifically, at Fig.12 As an example, the linear transfer module 31, the first lifting driver 33 and the second lifting driver 34 can each be a cylinder but are not limited thereto.

[0047] like Fig.18 As shown, as an example, the fan blade pressing mechanism 60 includes an external pressure driver 61, an internal pressure driver 62, an external pressure plate 63 and an internal pressure head 64. The external pressure plate 63 is assembled and connected with the output end 611 of the external pressure driver 61, and the external pressure plate 63 is provided with an escape hole 631 which runs through from top to bottom; the internal pressure head 64 is opposite to the escape hole 631 from top to bottom, and the internal pressure head 63 is also assembled and connected with the output end 621 of the internal pressure driver 62; the advantage of such a design is that the external pressure plate 63 presses the top of the bottom cover 210 from above, and the internal pressure head 64 presses the fan blades 250, thereby improving the reliability of fixing the fan blades 250 and the bottom cover 210. Specifically, Fig.18As an example, the external pressure driver 61 and the internal pressure driver 62 may each be a cylinder but are not limited thereto.

[0048] like Fig.19 As shown, as an example, the defective product unloading robot 70b includes a linear transfer mechanism 74 arranged opposite to the good product unloading conveyor line 90b, an upper and lower mechanism 75 mounted on the linear transfer mechanism 74, a rotary driver 76 mounted on the upper and lower mechanism 75, and a first grabbing member 77 and a second grabbing member 78 mounted on the output end 761 of the rotary driver 76. The linear transfer mechanism 74 is located next to the other outer side opposite to the rotary chain 41. This design improves the unloading efficiency of the defective product unloading robot 70b for unqualified fan bodies 200. Specifically, Fig.19 As an example, the linear transfer mechanism 74 may be a structure composed of a motor, a screw rod and a nut, the upper and lower mechanisms 75 may be but not limited to a cylinder, the rotary drive 76 may be but not limited to a rotary cylinder, and the first grabbing member 77 and the second grabbing member 78 may each be a pneumatic clamp.

[0049] like Fig. 20 As shown, as an example, the good product unloading robot 70c includes a horizontal transfer mechanism 71 across the rotating chain 41 and the good product unloading conveyor line 90b, a lifting mechanism 72 mounted on the horizontal transfer mechanism 71, and a pneumatic gripper 73 mounted on the lifting mechanism 72. The pneumatic gripper 72 is arranged downward to simplify the structure of the good product unloading robot 70c. Fig. 20 As an example, the horizontal transfer mechanism 71 may be a structure consisting of a motor, a screw rod and a nut, and the lifting mechanism 72 may be a cylinder but is not limited thereto.

[0050] like Fig.21As shown, as an example, the auxiliary labeling mechanism 90a includes an up-down moving module 91, a lifting slide 92, a rotary driver 93, a first pneumatic clamp 94, and a second pneumatic clamp 95.
