The workpiece conveyor line includes a turntable 13 disposed between the inner table board 11 and the outer table board 12 and a motor capable of driving the turntable 13 to rotate around the inner table board 11. A plurality of installation seats 101 are evenly arranged on the turntable 13. The pin punching mechanism 3, the positioning mechanism 4, the blade locking mechanism 5, and the blanking mechanism 6 can be arranged on the outer table board 12 or the inner table board 11 according to actual situations.

[0060] In order to further improve the degree of automation, a front cover installation mechanism 7 can also be added upstream of the pin punching mechanism 3 for automatically installing the front cover 22 on the fan head 21 and locking the screws to fix the front cover 22; an axle sleeve installation mechanism 8 can also be arranged between the blade locking mechanism 5 and the blanking mechanism 6 for automatically installing the axle sleeve 26 and lubricating the axle sleeve 26 before installing the axle sleeve 26.

[0061] The working process of the present invention is as follows: First, place the fan head 21 on the mounting seat 101 at the feeding station, and then the turntable 13 rotates at intervals, so that the fan head 21 sequentially passes through the working areas of the front cover mounting mechanism 7, the pin punching mechanism 3, the alignment mechanism 4, the blade lock mounting mechanism 5, the bushing mounting mechanism 8, and the blanking mechanism 6. In this process, first, the front cover 22 is automatically mounted on the fan head 21 by the front cover 22 mechanism and the screws are locked to fix the front cover 22; then, the impeller pin 24 is automatically mounted on the main shaft 23 of the fan head 21 by the pin punching mechanism 3; then, the main shaft 23 of the fan head 21 is rotated by the alignment mechanism 4 to adjust the fan head 21 to a suitable orientation; then, the blade lock 25 cover is automatically mounted on the main shaft 23 of the fan head 21 by the blade lock mounting mechanism 5; then, the bushing 26 is automatically mounted on the main shaft 23 by the bushing mounting mechanism 8 and the bushing 26 is lubricated before mounting the bushing 26; finally, the blanking mechanism 6 takes out the assembled fan head assembly 2.

[0062] Refer to Figures 2 to 7 , in a preferred embodiment of the present invention, the rotary drive assembly includes a shaft clamping device 331 capable of clamping the main shaft 23 and a rotary power device capable of driving the shaft clamping device 331 to rotate.

[0063] The working principle of the pin punching mechanism 3 is: when the fan head 21 is conveyed to the working area of the pin punching mechanism 3, the shaft clamping device 331 descends a certain height and clamps the main shaft 23 of the fan head 21, and then rotates under the driving action of the rotary power device, and the sensing assembly senses the position of the pin hole; at the same time, the shaft pin feeding device conveys an impeller pin 24 to the pin punching position. When the position of the pin hole meets the requirements, the sensing device sends this signal to the control system, and then the control system issues an order to stop the rotary power device, and then the pin punching device moves to drive the impeller pin 24 into the pin hole of the main shaft 23; finally, the shaft clamping device 331 is released, and the turntable 13 rotates to send away the workpiece that has been punched, so that another workpiece that has not been punched moves to the working area of the pin punching mechanism 3 to continue the next pin punching operation. The present invention realizes automatically finding the pin hole position on the main shaft 23 of the fan head 21 and automatically installing the impeller pin 24, with high working efficiency and reduced labor costs.

[0064] Specifically, a rotating seat 332 is provided on the pin punching bracket 31, the shaft clamping device 331 is installed on the rotating seat 332, and the rotary power device includes a first motor 333 and a transmission belt mechanism 334 connecting the first motor 333 and the rotating seat 332. The shaft clamping device 331 is a pneumatic claw fixedly installed on the rotating seat 332.

[0065] In some embodiments of the present invention, the above-mentioned rotary drive assembly may also adopt other structural forms. For example, a gear set or a chain drive mechanism may be used to replace the above-mentioned drive belt mechanism 334; or a friction drive structure may be used to drive the rotation of the main shaft 23 of the fan head 21.

[0066] In a preferred embodiment of the present invention, the pin feeding device includes a feeding device 341 capable of outputting impeller pins 24 one by one, a receiving seat 342 capable of receiving and temporarily storing the impeller pins 24, and a first walking mechanism capable of driving the receiving seat 342 to move to the pin insertion position.

[0067] Specifically, the feeding device 341 is a vibrating disk capable of outputting impeller pins 24 one by one. The first walking mechanism includes a lifting frame 351, a pin insertion lifting driver 352 capable of driving the lifting frame 351 to move up and down, a horizontal sliding seat 353 provided on the lifting frame 351, and a translation driver 354 capable of driving the horizontal sliding seat 353 to move left and right. The receiving seat 342 is fixed to the horizontal sliding seat 353, and the rotary drive assembly and the sensing assembly are both provided on the lifting frame 351. The pin insertion lifting driver 352 and the translation driver 354 are preferably air cylinders and electric cylinders.

[0068] The receiving seat 342 is provided with a receiving groove 3421 capable of accommodating the impeller pins 24. The pin insertion device includes a pushing member 361 capable of ejecting the impeller pins 24 from one end of the receiving groove 3421 and a pin insertion driver 362 capable of driving the pushing member 361 to move back and forth. The pin insertion driver 362 is preferably an air cylinder and an electric cylinder.

[0069] Preferably, the pushing member 361 includes a pushing block 3611 located outside the receiving groove 3421 and a convex portion 3612 provided on the pushing block 3611. The convex portion 3612 extends into the receiving groove 3421 and can move back and forth along the receiving groove 3421. The pushing member 361 has such a structure, with high strength and not easily broken.

[0070] In a preferred embodiment of the present invention, the pin feeding device may also adopt other structural forms. For example, a conveying pipe may be used to replace the above-mentioned first walking mechanism.

[0071] Refer to Figure 3 And Figure 4, a lifting frame 351 is provided on the pin punching bracket 31, the rotation drive assembly, the induction assembly, and the pin punching device are all provided on the lifting frame 351. A shaft resting member 371 and a shaft resting driver 372 capable of driving the shaft resting member 371 to move back and forth are provided on the lifting frame 351. The shaft resting member 371 is located on the other side opposite to the pin punching device. A groove cooperating with the main shaft 23 of the fan head 21 is provided on the shaft resting member 371. The shaft resting driver 372 is preferably a cylinder. Before pin punching, the main shaft 23 of the fan head 21 is leaned against by the shaft resting member 371, which is convenient for driving the impeller pin 24 into the main shaft 23.

[0072] In a preferred embodiment of the present invention, a through hole 3711 is provided on the shaft resting member 371 in the front-back direction. The induction assembly includes a positioning rod 381 capable of moving back and forth in the through hole 3711, an induction driver 382 capable of driving the positioning rod 381 to move back and forth, and an induction switch capable of measuring the position of the positioning rod 381 or the output shaft of the induction driver 382. The front end of the positioning rod 381 has a plug 3811 capable of being inserted into the pin hole of the main shaft 23. The induction driver 382 is preferably a cylinder, and the induction switch is a proximity switch, a Hall induction switch, a travel switch, or a photoelectric induction switch.

[0073] During the rotation of the main shaft 23, under the power action of the induction driver 382, the front end of the positioning rod 381 presses against the main shaft 23. When the main shaft 23 rotates in place, the plug 3811 at the front end of the positioning rod 381 is inserted into the pin hole. The position induction switch senses the position change of the positioning rod 381 and the output shaft of the induction driver 382, and then determines that the main shaft 23 has rotated in place. At this time, the rotation power device stops, and the pin punching step is carried out.

[0074] Furthermore, the impeller pin 24 is tubular and the plug 3811 can be inserted into the impeller pin 24. A limiting step 3812 capable of abutting against the end face of the impeller pin 24 is provided on the positioning rod 381. When pin punching, the limiting step 3812 on the positioning rod 381 can limit the length of both ends of the impeller pin 24 extending out of the main shaft 23, and the uniformity of the product is high.

[0075] In some embodiments of the present invention, the induction assembly can also adopt other structural forms, such as using an image recognition device to identify whether the pin hole on the main shaft 23 has rotated in place.

[0076] Refer to Figures 8 to 10, the alignment power device includes an alignment member 43 located above the moving path of the mounting base 101, an alignment lifting driver 441 capable of driving the alignment member 43 to move up and down, and a screwing driver 442 capable of driving the alignment member 43 to rotate. A clamping groove 4301 capable of cooperating with the impeller pin 24 on the main shaft 23 is provided at the lower end of the alignment member 43, and an avoidance structure capable of avoiding the upper part of the main shaft 23 is provided on the alignment member 43.

[0077] The alignment process is as follows: When the fan head 21 moves to the working area of the alignment mechanism 4, the alignment member 43 acts to drive the main shaft 23 of the fan head 21 to rotate, align the gearbox, and make the fan head 21 shake to a suitable orientation; during this process, the detection device detects the position of the shaking crank 27. When the shaking crank 27 moves to the target position, it indicates that the gearbox has been aligned. After the control system receives this signal, it controls the alignment lifting driver 441 to start, so that the alignment member 43 returns to the initial position, and then the turntable 13 rotates a certain angle to move the fan head 21 to the next working station.

[0078] In this solution, the method for the alignment member 43 to drive the main shaft 23 to rotate is as follows: When the mounting base 101 moves to directly below the alignment member 43, the alignment member 43 moves downward, so that the upper part of the main shaft 23 is inserted into the avoidance structure of the alignment member 43, and the impeller on the main shaft 23 is caught in the clamping groove 4301 at the lower end of the alignment member 43. Then the alignment member 43 rotates, and the main shaft 23 can be driven to rotate. Preferably, the number of the above clamping grooves 4301 is 2, 4, or 6, and the respective clamping grooves 4301 are evenly distributed along the circumferential direction of the alignment member 43.

[0079] In a preferred solution of the present invention, an alignment bracket 443 is provided on the frame 1, a lifting seat 444 is provided on the alignment bracket 443, the screwing driver 442 is arranged on the lifting seat 444, the screwing driver 442 is connected to the alignment member 43 to drive the alignment member 43 to rotate, and the alignment lifting driver 441 is connected to the lifting seat 444 to drive the lifting seat 444, the screwing driver 442, and the alignment member 43 to move up and down together. Specifically, the alignment lifting driver 441 is a cylinder, the screwing driver 442 is a motor, and the motor is connected to the upper end of the alignment member 43 through a coupling.

[0080] In a preferred solution of the present invention, the alignment member 43 includes a coupling rod 431 and a sleeve 432. The clamping groove 4301 is provided at the lower end of the sleeve 432. The upper end of the coupling rod 431 is directly or indirectly connected to the screwing driver 442. The upper part of the sleeve 432 is sleeved on the lower part of the coupling rod 431 and the two are in sliding fit. An anti-rotation and anti-disengagement structure for restricting the relative rotation and disengagement of the two is provided between the sleeve 432 and the coupling rod 431, and an elastic buffer member 433 is also provided between the sleeve 432 and the coupling rod 431.

[0081] As a preferred embodiment of the anti-rotation and anti-disengagement structure, the anti-rotation and anti-disengagement structure includes an axially closed groove 4321 provided on the sleeve 432 and a pin 4311 fixed to the coupling rod 431. The end of the pin 4311 is inserted into the axially closed groove 4321 and can move up and down within the axially closed groove 4321. A boss 4312 is provided on the coupling rod 431 above the sleeve 432, and the elastic buffer 433 is a spring provided between the upper end face of the sleeve 432 and the boss 4312. The above-mentioned avoidance structure is the inner hole of the sleeve 432. With such a structure of the alignment member 43, it is possible to avoid a rigid collision between the alignment member 43 and the impeller pin 24 on the main shaft 23 when the alignment member 43 moves downward. At the same time, during the process of the alignment member 43 rotating to drive the main shaft 23 to rotate, even if slipping occurs and the impeller pin 24 disengages from the card slot 4301, the sleeve 432 of the alignment member 43 continues to rotate, and the impeller pin 24 can also be caught in other card slots 4301.

[0082] In some embodiments of the present invention, the alignment member 43 can also adopt other structural forms. For example, the coupling rod 431 and the sleeve 432 are fixedly connected or designed as an integrally formed structure, and the depth of the card slot 4301 at the lower end of the sleeve 432 is increased to prevent the impeller pin 24 from slipping out of the card slot 4301 when the alignment member 43 rotates.

[0083] In a preferred embodiment of the present invention, a window for exposing the swing crank 27 of the fan head 21 is provided on one side of the mounting base 101, and the detection device includes a photoelectric sensor 46 provided on the frame 1.

[0084] In a preferred embodiment of the present invention, a window for exposing the swing button of the fan head 21 is provided on the other side of the mounting base 101, and a pressing device capable of pressing the swing button of the fan head 21 is provided on the frame 1.
