[0002] In the manufacturing process of the fan, the assembly of the impeller is a very critical step. This task requires the blades to be inserted into the storage slot of the silo one by one through the assembly equipment, and the lower protrusion of the blade is inserted into the matching hole of the lower wheel disc, and then the upper wheel disc is placed on all the blades, so that the upper protrusion of the blade is inserted into the matching hole of the upper wheel disc. After all the blades are inserted, the blades and the lower wheel disc rotate together with the upper wheel disc, and then the upper and lower protrusions of the blades are bent by the extrusion device, so that the blades are fixed between the upper and lower wheels, thereby completing the assembly of the impeller. However, the traditional method of inserting a single blade into the silo has a low assembly efficiency.

[0019] The driving unit includes a slide rail 101, a slider I 102 and a slider II 103; the workbench 1 is fixedly connected to two slide rails 101; all the slide rails 101 are slidably connected to a slider I 102, and all the sliders I 102 are fixedly connected to the fixing ring I 9; all the slide rails 101 are slidably connected to a slider II 103, and all the sliders II 103 are fixedly connected to the pressing device 12.

[0020] It also includes a traction unit; the traction unit includes a gear ring 201, a motor II 202, a gear 203, a sliding plate 204 and a rope 205; the fixed ring I9 is ​​rotatably connected to the gear ring 201, and the gear ring 201 is rotatably connected to the rotating ring 10; the fixed ring I9 is ​​bolted to the motor II 202; the output shaft of the motor II 202 is fixedly connected to the gear 203, and the gear 203 is meshed with the gear ring 201; all the guide plates 11 are slidably connected to 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 provided on the opposite sides, and the blades are sent into the storage tank of the rotary silo 7 through the sliding plate 204; all the sliding plates 204 are fixedly connected to the rope 205, and the other end of the rope 205 passes through the rotating ring 10 and is fixedly connected to the gear ring 201.

[0021] The working steps of the above embodiment are: first, manually place the lower wheel disc 100 on the placement ring 2, and drive the rotary silo 7 to rotate through the motor Ⅰ6. At this time, multiple discharge devices 8 push the blades into the storage slots corresponding to the rotary silo 7, so that multiple blades are placed in the storage slots corresponding to the rotary silo 7 at one time to improve the assembly efficiency of the impeller. However, since the rotary silo 7 is rotating, when multiple discharge devices 8 push the blades into the storage slots corresponding to the rotary silo 7, the positions of the blades and the storage slots cannot be determined. The blades are not aligned with the storage slots of the rotary silo 7, which makes the blades easy to get stuck, affecting the normal assembly of the impeller. Therefore, By setting a guide group aligned with the storage slot of the rotating silo 7 on the rotating ring 10, when the motor Ⅰ6 drives the rotating silo 7 to rotate, since the rotating silo 7 is engaged with the rotating ring 10, the rotating ring 10 will rotate synchronously with the rotating silo 7, and the guide group set on the rotating ring 10 is always directly opposite to the corresponding storage slot, so that when the multiple discharge devices 8 push the blades into the corresponding storage slots, the blades will first contact the guide group, and the guide plates 11 on the guide group will guide the blades to ensure that the blades can be smoothly inserted into the storage slots, so as to avoid the blades and the storage slots cannot be determined. The storage slots are not aligned with the blades, which affects the assembly efficiency of the impeller; It should be noted that the two guide plates 11 on the same guide group are set to be in an eight-shaped funnel shape, and the funnel-shaped opening faces the corresponding discharge device 8, so that the discharge device 8 pushes the blade toward the guide group, so that the blade will move toward the storage tank along the funnel-shaped opening; When all the storage slots of the rotating silos 7 have blades, the fixing ring Ⅰ9 and all the parts connected to it are driven upward by the slider Ⅰ102, and then the support plate 5 and all the parts connected to it are pulled downward by the push rod Ⅰ4, thereby driving the rotating silo 7 to move downward, and then the protruding part below the blade is inserted into the matching hole of the lower wheel disc 100, and then the push rod Ⅰ4 stops pulling, and then after the fixing ring Ⅰ9 moves upward for a certain distance, the slider Ⅰ102 stops moving, and then the upper wheel disc is manually placed on the blade, and the upper protruding part of the blade is inserted into the matching hole of the upper wheel disc, and then the pressing device 12 is driven downward by the slider Ⅱ103, so that the upper wheel disc is pressed by the pressing device 12, and then the upper wheel disc is pressed by the push rod Ⅰ4. The bending device 3 is moved to the left end of the lower wheel disc 100 and the upper wheel disc, and then the motor Ⅰ6 drives the rotating silo 7, the blades, the lower wheel disc 100 and the upper wheel disc to rotate. During the rotation of the blades, the lower wheel disc 100 and the upper wheel disc, the upper protruding part and the lower protruding part of the blade are bent by the bending device 3, so that the blade is fixed between the lower wheel disc 100 and the upper wheel disc, thereby completing the assembly of the fan impeller. In this way, the blades are inserted into the storage groove of the rotating silo 7 through multiple discharge devices 8, and the blades are guided to the storage groove of the rotating silo 7 through the guide plate 11, so that the efficiency of inserting the blades of the present invention is much higher than that of the prior art in which the blades are inserted into the silo and the wheel disc one by one through a discharge machine, thereby improving the production efficiency; It should be noted that since the blades are in the shape of thin plates, and the storage slots on the rotary silo 7 are inclined at a certain angle, when placing the blades, the inclination angle of the blades needs to be consistent with the inclination angle of the storage slots on the rotary silo 7, so that the blades can be placed in the storage slots on the rotary silo 7, and the guide plate 11, which is in the shape of an eight-shaped funnel, can only play a guiding role, and cannot rotate the inclination angle of the blades to be consistent with the inclination angle of the storage slots on the rotary silo 7, so that the blades still cannot enter the storage slots on the rotary silo 7. Therefore, by setting the guide plate 11 to be rotatably 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 slots on the rotary silo 7, when the discharge device 8 pushes the blades into the storage slots of the rotary silo 7, the blades will squeeze the guide plate 11, causing the guide plate 11 to rotate. The torsion spring connecting the guide plates 11 is in a compressed state, thereby further increasing the distance between the two guide plates 11 of the same guide group, and at the same time, the elastic membrane 11a is stretched, and then after the discharge device 8 completely pushes the blade out of the discharge 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 is reset, the blade will be clamped between the two guide plates 11 of the same guide group, and at this time, the two sliding plates 204 are in contact with the blade, and the blade is rotated to be consistent with the inclination angle of the storage slot on the rotary silo 7, so as to facilitate the subsequent pushing of the blade into the storage slot on the rotary silo 7, and at this time, the elastic membrane 11a can support the blade to prevent the blade from falling, so that the blade is temporarily stored between the two guide plates 11 of the same guide group; Subsequently, when all guide groups have temporarily stored blades, the motor I6 stops moving, and the motor II 202 drives the gear 203 to rotate, thereby driving the gear ring 201 to rotate through the gear 203, so that the gear ring 201 pulls the rope 205, and the rope 205 drives the sliding plate 204 to move in the direction close to the rotating silo 7. Since the sliding plate 204 fits with the blades at this time, the sliding plate 204 drives the blades to move in the direction close to the rotating silo 7, so that all the blades are accurately inserted into the storage slots of the rotating silo 7, thereby preventing the problem that the blades cannot be put into the storage slots on the rotating silo 7 due to the inclination angle of the blades being inconsistent with the inclination angle of the storage slots on the rotating silo 7; It should be noted that when the motor I6 drives the rotating silo 7 to rotate, the motor II 202 synchronously drives the gear 203 to rotate, so that the gear ring 201 and the rotating silo 7 rotate synchronously, avoiding the gear ring 201 pulling the rope 205 to drive the sliding plate 204 to move.

[0022] Example 2 On the basis of Example 1, Figure 4-8As shown, a correction unit is also included. The rotating hopper 7 and the rotating ring 10 are connected together with the correction unit, and the correction unit is used to correct the protruding part of the blade; the correction unit includes a correction bar Ⅰ301; the rotating ring 10 is fixedly connected with the same number of correction bars Ⅰ301 as the guide plate 11, and all the correction bars Ⅰ301 are located above the guide plate 11, and an eight-shaped inclined surface is arranged above two adjacent correction bars Ⅰ301; the upper protruding part of the blade is corrected by the correction bar Ⅰ301.

[0023] The correction unit also includes a spring telescopic rod Ⅰ302, a fixed ring Ⅱ303, a correction bar Ⅱ304, a push rod Ⅲ305 and an extrusion ring Ⅰ306; the rotating silo 7 is fixedly connected with three spring telescopic rods Ⅰ302; all the spring telescopic rods Ⅰ302 are fixedly connected with the fixed ring Ⅱ303; the fixed ring Ⅱ303 is rotatably connected with the correction bars Ⅱ304 of the same number as the guide plate 11, and all the correction bars Ⅱ304 are located below the guide plate 11, and an eight-shaped inclined surface is arranged below two adjacent correction bars Ⅱ304, and the fixed ring Ⅱ303 is provided with a baffle portion 303a on the outside of the rotation position of the correction bar Ⅱ304; the rotating silo 7 is fixedly connected with three push rods Ⅲ305; the telescopic ends of all the push rods Ⅲ305 are fixedly connected with the extrusion ring Ⅰ306, and the extrusion ring Ⅰ306 is in contact with the correction bar Ⅱ304 at one end close to the center of the rotating silo 7.

[0024] It also includes a storage block 401 ; all storage slots of the rotary silo 7 are fixedly connected with a storage block 401 , and a plurality of rubber blocks 401 a are arranged in the storage block 401 .

[0025] The rubber block 401a located at the upper part of the same storage block 401 is tilted in an inverted figure eight shape, and the rubber block 401a located at the lower part of the same storage block 401 is tilted in a right figure eight shape.

[0026] A metal block is provided at the end of the rubber block 401 a in the storage block 401 , and electromagnets are provided on the left and right sides of the storage block 401 .

[0027] It also includes a push rod IV402; the rotary silo 7 is fixedly connected to the push rod IV402, the telescopic end of the push rod IV402 is fixedly connected to the corresponding storage block 401, and the storage block 401 fixedly connected to the push rod IV402 and the rotary silo 7 are set to be slidably connected.

[0028] The working steps of the above embodiment are as follows: since the protruding parts above and below the blades are smaller in width than other parts, the blades are easily deformed after colliding and squeezing with other blades during production and transportation, and the deformation of the protruding parts of the blades will make it difficult to insert the protruding parts of the blades into the matching holes of the wheel disc. Therefore, through the several correction strips I301 on the fixing ring I9 and the several correction strips II304 on the fixing ring II303, when the sliding plate 204 drives the blades to be inserted into the storage slots of the rotating silo 7, the upper parts of the blades will be located at the corresponding positions. The lower part of the blade will be located between the two adjacent correction strips I301, and the lower part of the blade will be located between the two corresponding adjacent correction strips II304, and the correction strips I301 and II304 will be in close contact with the blade, so that when the fixing ring I9 moves upward, the fixing ring I9 will drive the correction strip I301 to move upward, so as to correct the convex part of the upper part of the blade. Before the push rod I4 pulls the support plate 5 and all the parts connected to it to move downward, the push rod III305 pushes the extrusion ring I306 to move downward, so that the extrusion ring I306 squeezes the correction strip II304. The correction bar II 304 is locked, so that the correction bar II 304 cannot rotate upward. Therefore, when the push rod III 305 pushes the extrusion ring I 306 to move downward, it will also drive the fixed ring II 303 to move downward, and the spring telescopic rod I 302 is stretched, so that the correction bar II 304 will correct the protruding part of the lower square of the blade to avoid the protruding part of the blade from being deformed, which makes it difficult to insert the protruding part of the blade into the matching hole of the wheel disc. When the blade is corrected, the extrusion ring I 306 is pulled upward by the push rod III 305, and the spring telescopic rod I 302 is driven to fix the fixed ring II 303. The fixed ring II 303 is reset, so that the correction strip II 304 is reset accordingly, and before the protruding portion below the blade is inserted into the matching hole of the lower wheel disc 100, the extrusion ring I 306 is pulled upward by the push rod III 305, so that the extrusion ring I 306 and the correction strip II 304 are no longer in contact, and a certain space is left. At this time, the correction strip II 304 will lose the restriction of the extrusion ring I 306. Under the influence of gravity, the correction strip II 304 rotates downward with its connection with the fixed ring II 303 as the axis, so as to avoid affecting the protruding portion below the blade from being inserted into the matching hole of the lower wheel disc 100; It should be noted that, since some of the protruding parts of the blades are bent, and the bending angle of some of the protruding parts of the blades is close to 180 degrees, the protruding parts of the blades and the normal parts of the blades are close to a folded state, making it difficult for the correction strips I 301 and II 304 to enter between the bent protruding parts and the normal parts of the blades. Therefore, the correction strips I 301 and II 304 are inclined when correcting the blades. , the correction strip I 301 and the correction strip II 304 can be inserted into the folded part of the protruding part of the blade, and then after the correction strip I 301 moves upward and the correction strip II 304 moves downward, the protruding part close to the folding bend is corrected by the correction strip I 301 and the correction strip II 304, thereby avoiding the problem that the correction strip I 301 and the correction strip II 304 are difficult to enter between the bent protruding part and the normal part of the blade due to the protruding part of the blade and the normal part of the blade being close to the folded state, resulting in the problem that the correction strip I 301 and the correction strip II 304 cannot be corrected; It should be noted that, since the storage groove of the rotating silo 7 has a limited fixing effect on the blade, when the correction bars Ⅰ301 and Ⅱ304 correct the blade, there is a possibility that the blade is brought out of the storage groove of the rotating silo 7, resulting in the correction bars Ⅰ301 and Ⅱ304 being unable to correct the protruding part of the blade. Therefore, a storage block 401 is provided in the storage groove of the rotating silo 7, so that when the correction bars Ⅰ301 and Ⅱ304 correct the blade, the blade will drive the rubber block 401a arranged in an eight-shaped tilt in the storage block 401 to rotate, and the rubber block 401a arranged in an eight-shaped tilt in the storage block 401 will rotate. When the shaped inclined rubber block 401a rotates to be perpendicular to the blade, the distance between the rubber blocks 401a becomes smaller because the length of the oblique side is longer than the straight side, so that the rubber block 401a will produce a stronger squeezing force on the blade, which greatly increases the friction force, so that the blade cannot move up or down, and then when the correction bar I 301 and the correction bar II 304 are corrected, the blade will not move up and down, thereby avoiding the correction bar I 301 or the correction bar II 304 from taking the blade out of the storage tank of the rotating silo 7, resulting in the problem that the correction bar I 301 and the correction bar II 304 cannot correct the blade; Furthermore, when inserting the protruding portion below the blade into the matching hole of the lower wheel disc 100, due to the large number of blades, it takes a certain amount of time to align all the blades with the matching holes of the lower wheel disc 100, resulting in reduced efficiency. Therefore, before the protruding portion below the blade is inserted into the matching hole of the lower wheel disc 100, the storage block 401 connected thereto is pushed downward by the push rod IV 402. After the storage block 401 moves downward for a certain distance, the push rod IV 402 stops pushing, so that the blades below the storage block 401 connected to the push rod IV 402 are aligned with the matching holes of the lower wheel disc 100. The protruding part of the square is lower than the protruding parts under other blades, so the protruding part under the blade in the storage block 401 connected to the push rod IV 402 will first contact the lower wheel disc 100, and at the same time, the rotating bin 7 is driven to rotate repeatedly by the motor I 6, so that the protruding part under the blade in the storage block 401 connected to the push rod IV 402 can be inserted into the matching hole of the lower wheel disc 100. When the protruding part under the blade in the storage block 401 connected to the push rod IV 402 is inserted into the matching hole of the lower wheel disc 100, it means that the blade is now After the push rod Ⅳ402 is reset, all the blades in the storage block 401 connected to the push rod Ⅳ402 do not move relative to the lower wheel disc 100. After that, all the blades are accurately inserted into the matching holes of the lower wheel disc 100. Thus, by first inserting the protruding portion under one blade into the matching hole of the lower wheel disc 100, the matching hole of the lower wheel disc 100 is aligned with the protruding portions under other blades. Subsequently, only the protruding portions under other blades need to be moved downward to be inserted into the matching holes of the lower wheel disc 100. This avoids the problem that it takes a certain amount of time for the blades and the matching holes of the lower wheel disc 100 to be aligned, resulting in reduced efficiency. 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 block at the end of the rubber block 401a, so that the rubber block 401a in the storage block 401 will fit together with the inner wall of the storage block 401, so that the rubber block 401a no longer restricts the movement of the blade in the up and down directions, and then after the impeller is assembled, the impeller can be taken out from the rotating silo 7.

[0029] Example 3 On the basis of Example 2, Figure 9-11As shown, it also includes a bending unit; the workbench 1 and the rotating silo 7 are jointly connected with the bending unit, and the bending unit is used to bend the blades; the bending unit includes a push rod V502, a fixed plate 503, a bending rod 504, a push rod VI505 and an extrusion strip 506; the workbench 1 is bolted with two push rods V502; the output end of the push rod V502 is fixedly connected with the fixed plate 503; the fixed plate 503 is rotatably connected with the bending rod 504, and the blades are bent by the bending rod 504; the fixed plate 503 is fixedly connected with two push rods VI505; the output end of the push rod VI505 is fixedly connected with the extrusion strip 506, and the extrusion strip 506 is rotatably connected with the bending rod 504.

[0030] The bending unit also includes support bars 501; thirty support bars 501 are fixedly connected to the rotating silo 7, and all the support bars 501 are staggered with the storage slots of the rotating silo 7; the middle part of the blade is supported by the support bars 501, so that the blade can be bent more evenly.

[0031] The working steps of the above embodiment are: during the assembly process of the impeller, the blades are usually required to be bent. In the prior art, the blades are usually inserted into the silo and the lower protruding portion of the blades is inserted into the lower wheel disc 100, and then the blades are squeezed to bend the blades. However, since the upper protruding portion of the blades has not been fixed, the upper and lower forces of the blades are uneven, resulting in inconsistent upper and lower bending of the blades after squeezing the blades. The present invention is to insert all the blades into the discharge device 8, and then insert all the blades into the upper wheel disc and the lower wheel disc 100 in sequence. Therefore, after all the blades are inserted into the rotary bin 7 and the fixing ring Ⅰ9 moves upward, the rotary bin 7 and the blades are driven to rotate by the motor Ⅰ6. When the storage block 401 rotates to a position opposite to the fixing plate 503, the motor Ⅰ6 stops rotating, and then the fixing plate 503 and all the parts connected to it are pushed to the left by the push rod Ⅴ502. When the fixing plate 503 contacts the rotary bin 7, the push rod Ⅴ502 stops pushing. At this time, the bending rod 504 is aligned with the outer side of the blade, and then the push rod Ⅵ 505 pushes the extrusion bar 506 to move to the left, so that the bending rod 504 rotates in the direction close to the blade, and supports the middle part of the blade through the support bar 501, so that the bending rod 504 squeezes the end of the blade away from the rotating bin 7, and then bends the blade. After the bending of the blade is completed, the fixed plate 503 and the push rod VI505 are driven to reset through the push rod V502 and the push rod VI505, and then the rotating bin 7 and the blade are driven to rotate again through the motor I6, so that all the blades are bent in turn, thereby avoiding the problem of inconsistent bending of the blades after squeezing the blades due to uneven upper and lower forces on the blades in the prior art; It should be noted that, since the blade is fixed by the rubber block 401a in the storage block 401, and the rubber block 401a is soft and has the ability to deform, the storage block 401 has a poor ability to fix the rubber layer, so that when the bending rod 504 bends the blade, the blade is easy to break away from the storage block 401. Therefore, when the fixing plate 503 moves to the left, the fixing plate 503 will be inserted between the blade and the rubber block 401a, so that the blade is squeezed on the rubber block 401a, so that the blade is fixed between the rubber block 401a and the fixing plate 503. On the plate 503, the stability of the blade is ensured when the blade is bent, and the blade is prevented from being separated from the rubber block 401a when the bending rod 504 bends the blade. Then after bending, in the process of pulling out the fixed plate 503 by the push rod V502, the push rod VI505 pushes the squeezing strip 506 to move to the left, so that the blade is fixed by the squeezing strip 506 to prevent the blade from being pulled out when the fixed plate 503 is pulled out. Then, after the fixed plate 503 is pulled out from the storage block 401, the squeezing strip 506 is pulled back to its original position by the push rod VI505.

Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
