[0024] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0026] Reference Figures 1 to 8 The present invention proposes an impeller pinning device, comprising: a frame 1, a pin hole finding device, a feeding device, a pinning assembly and a control system.

[0027] The pin hole finding device includes a rotating drive component that can drive the main shaft 22 of the fan head 21 to rotate and a sensing component that can sense whether the main shaft 22 has rotated into place; the loading device is used to output the impeller pins 23 one by one and transport the impeller pins 23 to the pinning position; the pinning component is used to drive the impeller pins 23 at the pinning position into the pin hole on the main shaft 22; the rotating drive component, the sensing component, the loading device, and the pinning component are respectively connected to the control system, and the control system controls these devices to act in coordination.

[0028] In a preferred embodiment of the present invention, the rotary drive assembly includes a shaft clamping device 31 capable of clamping the main shaft 22 of the fan head 21 and a rotary power device capable of driving the shaft clamping device 31 to rotate.

[0029] When the present invention is applied to a fan head 21 assembly machine, its working process is as follows: when the fan head 21 is transported to the working area of the impeller pinning device, the clamping device 31 descends to a certain height and clamps the main shaft 22 of the fan head 21, and then rotates under the driving action of the rotary power device, and the sensing component senses the position of the pin hole; at the same time, the feeding device transports an impeller pin 23 to the pinning 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 a command to stop the rotary power device, and then the pinning component moves to drive the impeller pin 23 into the pin hole of the main shaft 22; finally, the clamping device 31 is released, and the turntable on the fan head 21 assembly machine sends away the pinned workpiece, so that another workpiece that has not yet been pinned moves to the working area of the impeller pinning device to continue the next pinning operation. The present invention realizes the automatic pin hole location on the main shaft 22 of the fan head 21 and the automatic installation of the impeller pin 23, with high work efficiency and reduced labor costs.

[0030] Specifically, the frame 1 is provided with a rotating base 32, the shaft clamping device 31 is mounted on the rotating base 32, and the rotary power device includes a first motor 33 and a transmission belt mechanism 34 connecting the first motor 33 and the rotating base 32. The shaft clamping device 31 is a pneumatic clamp fixedly mounted on the rotating base 32.

[0031] In certain embodiments of the present invention, the above-mentioned rotation drive assembly may also adopt other structural forms, for example, a gear set or chain transmission mechanism may be used to replace the above-mentioned transmission belt mechanism 34; or a friction drive structure may be used to drive the main shaft 22 of the fan head 21 to rotate.

[0032] In a preferred embodiment of the present invention, the loading device includes a feeding device 41 capable of outputting the impeller pins 23 one by one, a workpiece mounting seat 42 capable of receiving and temporarily storing the impeller pins 23, and a walking mechanism capable of driving the workpiece mounting seat 42 to move to the pinning position.

[0033] Specifically, the feeding device 41 is a vibrating plate that can deliver the impeller pins 23 one by one. The traveling mechanism includes a lifting frame 51, a lifting actuator 52 that can drive the lifting frame 51 up and down, a horizontal slide 53 mounted on the lifting frame 51, and a translation actuator 54 that can drive the horizontal slide 53 left and right. The workpiece mounting base 42 is fixed to the horizontal slide 53, and the rotation drive assembly and the sensing assembly are both mounted on the lifting frame 51. The lifting actuator 52 and the translation actuator 54 are preferably pneumatic cylinders or electric cylinders.

[0034] The workpiece mounting base 42 is provided with a receiving groove 421 capable of accommodating the impeller pin 23. The pinning assembly includes a pusher 61 capable of ejecting the impeller pin 23 from one end of the receiving groove 421 and a pinning driver 62 capable of driving the pusher 61 to move forward and backward. The pinning driver 62 is preferably a pneumatic cylinder or an electric cylinder.

[0035] Preferably, the ejector 61 includes an ejector block 611 located outside the receiving groove 421 and a protrusion 612 provided on the ejector block 611. The protrusion 612 extends into the receiving groove 421 and can move forward and backward along the receiving groove 421. The ejector 61 adopts such a structure, which is high in strength and not easy to break.

[0036] In a preferred embodiment of the present invention, the loading device may also adopt other structural forms, for example, a conveying pipe may be used instead of the above-mentioned traveling mechanism.

[0037] Reference Figure 3 and Figure 4 The rotary drive assembly, the sensing assembly, and the pinning assembly are all mounted on the lifting frame 51. The lifting frame 51 is provided with a shaft member 71 and a shaft driver 72 capable of driving the shaft member 71 forward and backward. The shaft member 71 is located on the other side of the fan assembly opposite to the pinning assembly and is provided with a groove that mates with the main shaft 22 of the fan head 21. The shaft driver 72 is preferably a cylinder. Before pinning, the shaft member 71 is used to lean against the main shaft 22 of the fan head 21 to facilitate driving the impeller pin 23 into the main shaft 22.

[0038] In a preferred embodiment of the present invention, a guide hole 711 extending forward and backward is provided on the shaft member 71. The sensing assembly includes a positioning rod 81 capable of moving forward and backward within the guide hole 711, an inductive driver 82 capable of driving the positioning rod 81 to move forward and backward, and an inductive switch capable of measuring the position of the output shaft of the positioning rod 81 or the inductive driver 82. The front end of the positioning rod 81 has a plug 811 capable of being inserted into the pin hole of the main shaft 22. The inductive driver 82 is preferably a pneumatic cylinder, and the inductive switch is a proximity switch, a Hall effect sensor, a travel switch, or a photoelectric sensor.

[0039] During the rotation of the main shaft 22, under the power of the induction driver 82, the front end of the positioning rod 81 is pressed against the main shaft 22. When the main shaft 22 is rotated to the position, the plug 811 at the front end of the positioning rod 81 is inserted into the pin hole. The position sensing switch senses the position change of the positioning rod 81 and the output shaft of the induction driver 82, and determines that the main shaft 22 has been rotated to the position. At this time, the rotating power device is stopped and the pinning step is performed.

[0040] Furthermore, the impeller pin 23 is tubular, and the plug 811 can be inserted into the impeller pin 23. The positioning rod 81 is provided with a stopper step 812 that can abut against the end surface of the impeller pin 23. When the pin is driven, the stopper step 812 on the positioning rod 81 can limit the length of the impeller pin 23 extending from the main shaft 22 at both ends, thereby improving the uniformity of the product.

[0041] In certain embodiments of the present invention, the sensing component may also adopt other structural forms, such as using an image recognition device to identify whether the pin hole on the main shaft 22 is rotated into place.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
