[0035] The driving unit includes slide rail 101, slide block I 102 and slide block II 103; the workbench 1 is fixedly connected with two slide rails 101; all the slide rails 101 are slidably connected with a slide block I 102, and all the slide blocks I 102 are fixedly connected with the fixed ring I 9; all the slide rails 101 are slidably connected with a slide block II 103, and all the slide blocks II 103 are fixedly connected with the pressing device 12.

[0036] It also includes a traction unit; the traction unit includes a tooth ring 201, a motor II 202, a gear 203, a sliding plate 204 and a rope 205; the fixed ring I 9 is rotatably connected with the tooth ring 201, and the tooth ring 201 is rotatably connected with the rotating ring 10; the fixed ring I 9 is bolted with the motor II 202; the output shaft of the motor II 202 is fixedly connected with the gear 203, and the gear 203 is engaged with the tooth ring 201; all the guide plates 11 are slidably connected with a sliding plate 204, and all the sliding plates 204 are provided with a rubber layer, and the rubber layers of the two sliding plates 204 on the same guide group are arranged on the opposite sides, and the blade is sent into the storage groove of the rotary bin 7 through the sliding plate 204; all the sliding plates 204 are fixedly connected with the rope 205, and the other end of the rope 205 penetrates through the rotating ring 10 and is fixedly connected with the tooth ring 201.

[0037] The working steps of the above embodiment are: first, manually place the lower disc 100 on the placing ring 2, and drive the rotating hopper 7 to rotate through the motor I 6, at this time, the plurality of dispensing devices 8 push the blades into the corresponding storage grooves of the rotating hopper 7, so that a plurality of blades are placed in the corresponding storage grooves of the rotating hopper 7 at a time, so as to improve the assembly efficiency of the impeller, but since the rotating hopper 7 is rotating, when the plurality of dispensing devices 8 push the blades into the corresponding storage grooves of the rotating hopper 7, the position of the blades and the storage grooves cannot be determined, the blades and the storage grooves of the rotating hopper 7 are not aligned, so that the blades are easily stuck, affecting the normal assembly of the impeller, therefore, by arranging the guide group on the rotating ring 10 which is aligned with the storage grooves of the rotating hopper 7, when the rotating hopper 7 is driven to rotate by the motor I 6, since the rotating hopper 7 is engaged with the rotating ring 10, the rotating ring 10 will rotate synchronously with the rotating hopper 7, the guide group arranged on the rotating ring 10 is always opposite to the corresponding storage groove, so that when the plurality of dispensing devices 8 push the blades into the corresponding storage grooves, the blades will first contact the guide group, and the blades are guided by the guide plate 11 on the guide group, so as to ensure that the blades can be smoothly inserted into the storage grooves, avoiding that the position of the blades and the storage grooves cannot be determined, resulting in that the blades and the storage grooves of the rotating hopper 7 are not aligned, affecting the assembly efficiency of the impeller;

[0038] It should be noted that the two guide plates 11 on the same guide group are arranged in a funnel shape, and the funnel-shaped opening faces the corresponding dispensing device 8, so as to facilitate the dispensing device 8 to push the blades to the guide group, so that the blades will move along the funnel-shaped opening to the storage groove;

[0039] When all the storage tanks of the rotary hopper 7 have blades, the fixed ring I 9 and all the parts connected thereto are moved upward by the sliding block I 102, and then the support plate 5 and all the parts connected thereto are moved downward by the push rod I 4, thereby moving the rotary hopper 7 downward, and then the protruding part below the blade is inserted into the matching hole of the lower disc 100, and then the push rod I 4 stops pulling, and then the sliding block I 102 stops moving after the fixed ring I 9 moves upward by a certain distance, and then the upper disc is placed on the blade by hand, and the protruding part above the blade is inserted into the matching hole of the upper disc, and then the pressing device 12 is moved downward by the sliding block II 103, thereby pressing the upper disc by the pressing device 12, and then the bending device 3 is moved to the left end of the lower disc 100 and the upper disc, and then the rotary hopper 7, the blade, the lower disc 100 and the upper disc are rotated by the motor I 6, and in the process of rotating the blade, the lower disc 100 and the upper disc, the upper protruding part and the lower protruding part of the blade are bent by the bending device 3, thereby fixing the blade between the lower disc 100 and the upper disc, thereby completing the assembly of the fan impeller, so that the blades are inserted into the storage tank of the rotary hopper 7 through the plurality of discharging devices 8, and the blades are guided into the storage tank of the rotary hopper 7 through the guide plate 11, so that the efficiency of inserting the blades of the present application is much higher than that of the prior art by inserting the blades into the hopper and the disc one by one through a discharging machine, thereby improving the production efficiency;

[0040] It should be noted that since the blade is thin plate-shaped and the storage groove on the rotary bin 7 is inclined at an angle, when placing the blade, the inclination angle of the blade needs to be consistent with the inclination angle of the storage groove on the rotary bin 7, so that the blade can be placed into the storage groove on the rotary bin 7. The guide plate 11 in the shape of an eight-shaped funnel can only play a guiding role and cannot rotate the inclination angle of the blade to be consistent with the inclination angle of the storage groove on the rotary bin 7, so that the blade still cannot enter the storage groove on the rotary bin 7. Therefore, by arranging the guide plate 11 to be connected by a torsion spring, and the inclination angle of the guide plate 11 in the initial state is consistent with the inclination angle of the storage groove on the rotary bin 7, so that in the process of the discharging device 8 pushing the blade into the storage groove of the rotary bin 7, the blade will press the guide plate 11, so that the guide plate 11 rotates. At this time, the torsion spring connecting the guide plate 11 is in a compressed state, so that the distance between the two guide plates 11 of the same guide group is further increased, and the elastic film 11a is stretched. Subsequently, after the blade is completely pushed out of the discharging device 8 by the discharging device 8, the blade no longer presses the guide plate 11, and then the torsion spring connecting the guide plate 11 drives the guide plate 11 to reset, so that the guide plate 11 pushes the blade to rotate, so that after the guide plate 11 completes the reset, the blade will be clamped between the two guide plates 11 of the same guide group. At this time, the two sliding plates 204 are in contact with the blade and make the blade rotate to be consistent with the inclination angle of the storage groove on the rotary bin 7, so as to facilitate subsequent pushing of the blade into the storage groove on the rotary bin 7. At this time, the elastic film 11a can support the blade to prevent the blade from falling, thereby temporarily storing the blade between the two guide plates 11 of the same guide group.

[0041] Subsequently, when all the guide groups temporarily store the blades, the motor I 6 stops moving. At this time, the motor II 202 drives the gear 203 to rotate, thereby driving the gear ring 201 to rotate, so that the gear ring 201 pulls the rope 205, thereby driving the sliding plate 204 to move towards the rotary bin 7. Since the sliding plate 204 is in contact with the blade at this time, the sliding plate 204 drives the blade to move towards the rotary bin 7, thereby accurately inserting all the blades into the storage groove of the rotary bin 7, thereby preventing the problem that the blade cannot be placed into the storage groove on the rotary bin 7 due to the inconsistency between the inclination angle of the blade and the inclination angle of the storage groove on the rotary bin 7.

[0042] It should be noted that when the motor I 6 drives the rotary bin 7 to rotate, the motor II 202 synchronously drives the gear 203 to rotate, so that the gear ring 201 synchronously rotates with the rotary bin 7, avoiding that the gear ring 201 pulls the rope 205 to drive the sliding plate 204 to move.

[0043] Example 2

[0044] On the basis of embodiment 1, as shown in Figures 4-8 It also includes a correction unit, the rotary bunker 7 and the rotating ring 10 are jointly connected with the correction unit, and the correction unit is used for correcting the blade protruding part; the correction unit includes a correction strip I 301; the rotating ring 10 is fixedly connected with the correction strip I 301 consistent with the number of the guide plate 11, and all the correction strip I 301 is located above the guide plate 11, and the upper part of the adjacent two correction strip I 301 is provided with an eight-shaped slope; the upper part of the blade is corrected by the correction strip I 301.

[0045] The correction unit also includes a spring telescopic rod I 302, a fixed ring II 303, a correction strip II 304, a push rod III 305 and an extrusion ring I 306; the rotary bunker 7 is fixedly connected with three spring telescopic rods I 302; all the spring telescopic rods I 302 are fixedly connected with the fixed ring II 303; the fixed ring II 303 is rotatably connected with the correction strip II 304 consistent with the number of the guide plate 11, and all the correction strip II 304 is located below the guide plate 11, and the lower part of the adjacent two correction strip II 304 is provided with an eight-shaped slope, and the fixed ring II 303 is provided with a baffle part 303a outside the rotating position of the correction strip II 304; the rotary bunker 7 is fixedly connected with three push rods III 305; the telescopic end of all the push rods III 305 is fixedly connected with the extrusion ring I 306, and the extrusion ring I 306 is in contact with the end of the correction strip II 304 close to the center of the rotary bunker 7.

[0046] It also includes a storage block 401; all the storage grooves of the rotary bunker 7 are fixedly connected with one storage block 401, and a plurality of rubber blocks 401a are arranged in the storage block 401.

[0047] The rubber blocks 401a located on the upper part of the same storage block 401 are arranged in an inverted eight-shaped slope, and the rubber blocks 401a located on the lower part of the same storage block 401 are arranged in a positive eight-shaped slope.

[0048] The end of the rubber block 401a in the storage block 401 is provided with a metal block, and the left side and the right side of the storage block 401 are provided with electromagnets.

[0049] It also includes a push rod IV 402; the rotary bunker 7 is fixedly connected with the push rod IV 402, the telescopic end of the push rod IV 402 is fixedly connected with the corresponding storage block 401, and the storage block 401 fixedly connected with the push rod IV 402 is slidingly connected with the rotary bunker 7.

[0050] The working steps of the above embodiment are as follows: due to the fact that the protruding portions above and below the blade have a smaller width than other portions, the blade is prone to deformation after being pressed by other blades during production and transportation; and the deformed protruding portions of the blade make it difficult to insert the protruding portions of the blade into the matching holes of the wheel disc. Therefore, a plurality of correction bars 1301 on the fixing ring I 9 and a plurality of correction bars 1304 on the fixing ring II 303 are arranged to make the upper portion of the blade located between the corresponding adjacent two correction bars 1301 and the lower portion of the blade located between the corresponding adjacent two correction bars 1304 when the sliding plate 204 drives the blade to be inserted into the storage groove of the rotating stock bin 7, and the correction bars 1301 and the correction bars 1304 are in close contact with the blade, so that the fixing ring I 9 drives the correction bars 1301 to move upward when the fixing ring I 9 moves upward, thereby correcting the deformed protruding portions above the blade. Before the push rod I 4 drives the support plate 5 and all the parts connected thereto to move downward, the push rod III 305 drives the extrusion ring I 1306 to move downward, so that the extrusion ring I 1306 extrudes the correction bars 1304. Since the baffle part 303a blocks the correction bars 1304, the correction bars 1304 cannot rotate upward, so that the push rod III 305 drives the extrusion ring I 1306 to move downward, thereby driving the fixing ring II 303 to move downward, and the spring telescopic rod I 302 is stretched, so that the correction bars 1304 correct the deformed protruding portions below the blade, thereby avoiding the problem that the protruding portions of the blade are difficult to insert into the matching holes of the wheel disc due to the deformation of the protruding portions of the blade. When the blade is corrected, the push rod III 305 drives the extrusion ring I 1306 to move upward, the spring telescopic rod I 302 drives the fixing ring II 303 to reset, so that the correction bars 1304 reset, and before the protruding portions below the blade are inserted into the matching holes of the lower wheel disc 100, the push rod III 305 drives the extrusion ring I 1306 to move upward, so that the extrusion ring I 1306 is no longer in contact with the correction bars 1304 and a certain space is left. At this time, the correction bars 1304 will lose the restriction of the extrusion ring I 1306, and the correction bars 1304 will rotate downward around the connection between the correction bars 1304 and the fixing ring II 303 under the influence of gravity, thereby avoiding affecting the insertion of the protruding portions below the blade into the matching holes of the lower wheel disc 100.

[0051] It should be noted that due to the bending of the convex part of the blade, the bending angle of the convex part of the blade is close to one hundred and eighty degrees, at this time the convex part of the blade and the normal part of the blade are close to the folding state, so that the correction strip 301 and the correction strip 304 are difficult to enter between the folded convex part and the normal part of the blade, so that the correction strip 301 and the correction strip 304 on the inclined surface can be inserted into the folded convex part of the blade during the correction of the blade, and then after the correction strip 301 moves upward and the correction strip 304 moves downward, the folded convex part is corrected by the correction strip 301 and the correction strip 304, thereby avoiding the problem that the correction strip 301 and the correction strip 304 are difficult to enter between the folded convex part and the normal part of the blade due to the convex part of the blade and the normal part of the blade close to the folding state, resulting in the problem of being unable to correct;

[0052] It should be noted that due to the limited fixing effect of the storage groove of the rotary bin 7 on the blade, the blade is taken out of the storage groove of the rotary bin 7 during the correction of the blade by the correction strip 301 and the correction strip 304, so that the correction strip 301 and the correction strip 304 cannot correct the convex part of the blade, so the storage block 401 is arranged in the storage groove of the rotary bin 7, so that the rubber block 401a in the storage block 401 is rotated by the blade during the correction of the blade by the correction strip 301 and the correction strip 304, and when the rubber block 401a is rotated to be perpendicular to the blade, the length of the inclined side is higher than that of the straight side, so that the distance between the rubber blocks 401a is reduced, so that the rubber blocks 401a can generate stronger extrusion force on the blade, so that the friction force is greatly increased, so that the blade cannot move upward or downward, and thus the blade will not move up and down during the correction of the correction strip 301 and the correction strip 304, thereby avoiding the problem that the correction strip 301 or the correction strip 304 takes the blade out of the storage groove of the rotary bin 7, resulting in the problem that the correction strip 301 and the correction strip 304 cannot correct the blade;

[0053] And, when the blade lower protruding part is inserted into the matching hole of the lower disc 100, because the number of blades is large, it takes a certain amount of time to align all the blades with the matching hole of the lower disc 100, resulting in a decrease in efficiency, so before the blade lower protruding part is inserted into the matching hole of the lower disc 100, the connected storage block 401 is pushed downward by the push rod IV 402, and when the storage block 401 moves downward by a certain distance, the push rod IV 402 stops pushing, so that the blade lower protruding part in the storage block 401 connected by the push rod IV 402 is lower than the other blade lower protruding parts, so the blade lower protruding part in the storage block 401 connected by the push rod IV 402 will contact the lower disc 100 first, and at the same time, the rotating hopper 7 is repeatedly rotated by the motor I 6, so that the blade lower protruding part in the storage block 401 connected by the push rod IV 402 can be inserted into the matching hole of the lower disc 100, and when the blade lower protruding part in the storage block 401 connected by the push rod IV 402 is inserted into the matching hole of the lower disc 100, it means that the blade has been aligned with the matching hole of the lower disc 100 at this time, so that the subsequent other blade lower protruding parts can be directly inserted into the matching hole of the lower disc 100, and then after the rotating hopper 7 continues to move downward, the connected storage block 401 is pulled upward by the push rod IV 402 to reset, and the speed of the storage block 401 connected by the push rod IV 402 moving upward is kept consistent with the speed of the rotating hopper 7 moving downward, so that the blade in the storage block 401 connected by the push rod IV 402 does not move relative to the lower disc 100, and then after the push rod IV 402 is reset, all the blades are accurately inserted into the matching hole of the lower disc 100, so that by first inserting a blade lower protruding part into the matching hole of the lower disc 100, the matching hole of the lower disc 100 is aligned with the other blade lower protruding parts, so that subsequent only the other blade lower protruding parts need to be moved downward to be inserted into the matching hole of the lower disc 100, thereby avoiding the problem of a decrease in efficiency due to the time required to align the blades with the matching hole of the lower disc 100.

[0054] It should be noted that after the impeller is assembled, the electromagnets on the left and right sides of the storage block 401 are activated, so that the electromagnets on the left and right sides of the storage block 401 attract the metal blocks at the end of the rubber block 401a, so that the rubber block 401a in the storage block 401 will be attached to the inner wall of the storage block 401, so that the rubber block 401a no longer restricts the upward and downward movement of the blade, and then the impeller can be removed from the rotating hopper 7 after the impeller is assembled.

[0055] Example 3

[0056] Based on example 2, as Figures 9-11Also shown, further comprising a bending unit; the workbench 1 and the rotary hopper 7 are commonly connected with the bending unit, the bending unit is used for bending the blade; the bending unit comprises a push rod V 502, a fixed plate 503, a bending rod 504, a push rod VI 505 and an extrusion strip 506; the workbench 1 is bolted with two push rods V 502; the output end of the push rod V 502 is fixedly connected with the fixed plate 503; the fixed plate 503 is rotatably connected with the bending rod 504, and the blade is bent through the bending rod 504; the fixed plate 503 is fixedly connected with two push rods VI 505; the output end of the push rod VI 505 is fixedly connected with the extrusion strip 506, and the extrusion strip 506 is rotatably connected with the bending rod 504.

[0057] The bending unit further comprises a support strip 501; the rotary hopper 7 is fixedly connected with thirty support strips 501, and all the support strips 501 are distributed in a staggered manner with the storage groove of the rotary hopper 7; the middle part of the blade is supported through the support strip 501, so that the blade can be bent more uniformly.

[0058] The working steps of the above embodiment are: during the assembly of the impeller, the blade usually needs to be bent, and in the prior art, after the blade is inserted into the hopper and the lower protruding part of the blade is inserted into the lower disc 100, the blade is extruded to bend the blade, but since the upper protruding part of the blade has not been fixed, the upper and lower forces of the blade are uneven, which causes the upper and lower bending conditions of the blade to be inconsistent after the blade is extruded;

[0059] And the present application is to insert all the blades into the material placing device 8, and then sequentially insert all the blades into the upper disc and the lower disc 100, so that after all the blades are inserted into the rotary hopper 7, and the fixed ring I 9 moves upward, the rotary hopper 7 and the blades are rotated by the motor I 6, when the storage block 401 rotates to the position opposite to the fixed plate 503, the motor I 6 stops rotating, then the fixed plate 503 and all the parts connected thereto are pushed to move leftward by the push rod V 502, when the fixed plate 503 contacts with the rotary hopper 7, the push rod V 502 stops pushing, at this time the bending rod 504 is aligned with the outer side of the blade, then the extrusion strip 506 is pushed to move leftward by the push rod VI 505, so that the bending rod 504 rotates towards the blade, and the middle part of the blade is supported by the support strip 501, so that the end of the blade away from the rotary hopper 7 is extruded by the bending rod 504, thereby bending the blade, then after the bending of the blade is completed, the fixed plate 503 and the push rod VI 505 are reset by the push rod V 502 and the push rod VI 505, then the rotary hopper 7 and the blades are rotated by the motor I 6 again, so as to sequentially bend all the blades, thereby avoiding the problem that the upper and lower bending conditions of the blade are inconsistent after the blade is extruded due to the uneven upper and lower forces of the blade in the prior art;

[0060] It should be noted that since the blade is fixed by the rubber block 401a in the storage block 401, the rubber block 401a is soft and has deformation ability, so the fixing ability of the storage block 401 to the rubber layer is poor, so when the bending rod 504 bends the blade, the blade is easy to separate from the storage block 401, so when the fixed plate 503 moves to the left, the fixed plate 503 will be inserted between the blade and the rubber block 401a, so that the blade is pressed on the rubber block 401a, so that the blade is fixed on the rubber block 401a and the fixed plate 503, which ensures the stability of the blade when bending, prevents the blade from separating from the rubber block 401a when the bending rod 504 bends the blade, and then in the process of pulling out the fixed plate 503 after bending, the pushing rod VI 505 pushes the pressing strip 506 to move to the left, so that the blade is fixed by the pressing strip 506, preventing the blade from being taken out when the fixed plate 503 is pulled out, and then after the fixed plate 503 is pulled out from the storage block 401, the pressing strip 506 is pulled back by the pushing rod VI 505.

[0061] The above embodiments are only preferred embodiments of the present application and are not intended to limit the scope of the present application. Any equivalent changes made in accordance with the content described in the claims of the present application shall be included within the scope of the claims of the present application.
