DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0027] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0029] Referring to Figures 1 - 4 , this utility model discloses a wind wheel pressing and assembling machine for a cooling fan, which includes a conveying assembly 10, a dust suction and positioning assembly 20, a feeding assembly 30, a transfer clamping member 50, and a pressing assembly 60. The above-mentioned conveying assembly 10 is used to convey a first workpiece in a conveying manner. Specifically, the dust suction and positioning assembly 20 includes a positioning frame 21 and a positioning shaft 22. The positioning shaft 22 is installed on the positioning frame 21, and an air suction channel is provided in the positioning frame 21. A plurality of air suction holes are provided on the positioning shaft 22, and the air suction holes communicate with the air suction channel.

[0030] In addition, the feeding assembly 30 includes a feeding member, a feeding driving member, and a feeding clamping member 40. The feeding member can support a second workpiece, and the feeding driving member can drive the feeding member to move up and down; the feeding clamping member 40 reciprocates between the feeding member and the positioning shaft 22 to clamp and transfer the second workpiece. The transfer clamping member 50 reciprocates between the positioning shaft 22 and the conveying assembly 10 to clamp and transfer the second workpiece. The pressing assembly 60 is arranged in the conveying direction of the conveying assembly 10, and the pressing assembly 60 presses the second workpiece onto the first workpiece; the transfer clamping member 50 and the pressing assembly 60 are sequentially spaced apart in the conveying direction of the conveying assembly 10.

[0031] Based on the above structure, when using the wind wheel pressing and assembling machine for a cooling fan of this utility model, taking the first workpiece as the fan base and the second workpiece as the wind wheel as an example, and there are a wind wheel feeding station and a pressing station in the conveying direction of the conveying assembly 10;

[0032] When the two are pressed and assembled, the fan base can be sequentially conveyed to the wind wheel feeding station through the conveying assembly 10, and the fan base is sequentially fed through the feeding member. The feeding clamping member 40 can clamp the wind wheel on the feeding member and transfer it to the positioning shaft 22, and the positioning shaft 22 positions the rotating seat of the wind wheel. Thereafter, the dust suction channel of the positioning frame 21 can be connected to an external dust suction device. By pumping air with the external dust suction device, a negative pressure is generated in the dust suction channel. Since the dust suction channel communicates with the plurality of air suction holes of the positioning shaft 22, a continuous negative pressure is generated by suction in the dust suction channel, and the dust in the rotating seat of the wind wheel is sucked through the plurality of air suction holes.

[0033] After the positioning shaft 22 vacuums and positions the wind wheel, the transfer gripper 50 grips the wind wheel on the positioning shaft 22 and transfers it to the fan base at the wind wheel loading station of the conveying assembly 10. After that, the conveying assembly 10 conveys the fan base with the wind wheel to the pressing station, and after the pressing station, the pressing assembly 60 presses and assembles the wind wheel and the fan base.

[0034] In this way, the feeding part and the conveying assembly 10 continuously feed the wind wheel and the fan base respectively. The feeding gripper 40 continuously transfers the wind wheel to the positioning shaft 22 for vacuum positioning. After the positioned wind wheel is gripped by the transfer gripper 50 and transferred to the fan base of the conveying assembly 10, it is then conveyed to the pressing assembly 60. The whole assembly process is continuous and highly automated, improving the pressing and assembling efficiency.

[0035] Furthermore, an installation plate is provided on the outer periphery of the positioning frame 21, and a first positioning sensor 23 is provided on the installation plate. The first positioning sensor 23 detects the second workpiece on the positioning shaft 22. In this way, when positioning the wind wheel, the rotating seat of the wind wheel is sleeved on the positioning shaft 22, and the first positioning sensor 23 detects and positions the position of the rotating seat of the wind wheel. Taking the first positioning sensor 23 as a photoelectric sensor or an infrared sensor as an example, after the rotating seat of the wind wheel is sleeved on the positioning shaft 22, if the optical path of the photoelectric sensor or the infrared sensor is just blocked, it can indicate accurate positioning. If the optical path is not blocked, it indicates that there is an offset or eccentricity, and adjustment is required. In this way, the first positioning sensor 23 and the positioning shaft 22 cooperate to complete the positioning of the wind wheel, making the positioning more accurate.

[0036] Furthermore, the multiple suction holes in this embodiment include a first suction hole 221 and multiple second suction holes 222. The first suction hole 221 is provided in the middle of the positioning shaft 22, and the first suction hole 221 penetrates through to the top surface of the positioning shaft 22. The first suction hole 221 communicates with the suction channel; the multiple second suction holes 222 are provided in the circumferential direction of the positioning shaft 22 and communicate with the first suction hole 221. In this way, when performing dust suction, the rotating seat of the wind wheel is sleeved on the positioning shaft 22. The middle first suction hole 221 sucks dust in the middle of the rotating seat of the wind wheel, and the multiple second suction holes 222 suck dust in the circumferential direction of the rotating seat of the wind wheel, making the dust suction more comprehensive and the dust removal effect better.

[0037] Furthermore, the feeding assembly 30 further includes a feeding frame 31, and the feeding frame 31 is provided with multiple through holes; the feeding part includes a feeding table 33 and multiple lifting rods 32, and the feeding driving part is used to drive the feeding table 33 to move up and down; the multiple lifting rods 32 are arranged on the feeding table 33 and are evenly spaced; the multiple lifting rods 32 are arranged in one-to-one correspondence with the multiple through holes; the multiple lifting rods 32 are used to extend into the feeding frame 31 through the multiple through holes after the feeding table 33 moves upward.

[0038] When loading the wind wheels, multiple wind wheels can be placed on a tray. By stacking multiple trays with wind wheels into the loading frame 31, and then performing the loading action, the loading driving member is started. The loading driving member drives the loading table 33 to move upward. Multiple lifting rods 32 on the loading table 33 can move upward simultaneously, extend through multiple through holes of the loading frame 31, and lift the tray with the wind wheel upward. In this way, the tray at the top of the loading frame 31 can be pushed out of the loading frame 31, and then the loading clamping member 40 can clamp the wind wheel on the topmost tray.

[0039] After the wind wheel on the topmost tray is clamped and transferred, the topmost tray can be transferred. Then, the loading driving member drives the loading table 33 to continue moving upward by one position, pushing out the next tray from the loading frame 31. In this way, the continuous transfer and loading of the wind wheels in the loading frame 31 can be realized.

[0040] Further, there are multiple loading frames 31 and loading members. A blanking bracket 70 is provided between two adjacent loading members. After the wind wheel on the tray is clamped and transferred, the loading clamping member 40 can clamp the tray and transfer it to the blanking bracket 70. The trays after the material is taken can be stacked in the blanking bracket 70 to realize the sequential stacking of the trays.

[0041] Further, the loading assembly 30 can also include a height detection sensor 34. The height detection sensor 34 is provided outside the loading frame 31 and is used to detect the height of the second workpiece in the loading frame 31. In this way, when the loading table 33 rises and drives the lifting rod 32 to lift the tray to the height detected by the height detection sensor 34, the height detection sensor 34 can send a height signal to the loading driving member, and the loading driving member stops, and then the wind wheel transfer action can start.

[0042] Of course, the above height detection sensor 34 can also be selected as an optoelectronic sensor, an infrared sensor, etc. in the prior art, and the optical path of the optoelectronic sensor and the infrared sensor is blocked by the top height of the tray as the height signal. It can also be a touch switch. After the tray is pushed out of the loading frame 31 and touches the touch switch, a touch signal can also be sent to the loading driving member.

[0043] Further, the loading driving member includes a motor 35, a lead screw 36, a threaded sleeve, and a guiding mechanism. The rotating shaft of the motor 35 is connected to the lead screw 36. The threaded sleeve is installed on the loading table 33 and is threadedly sleeved outside the lead screw 36. The guiding mechanism is used to guide the loading table 33 to move up and down when the lead screw 36 rotates. The motor 35 drives the lead screw 36 to rotate. With the threaded fit between the lead screw 36 and the threaded sleeve, and at the same time, the guiding mechanism restricts the rotation of the loading table 33 connected to the threaded sleeve. Thus, with the threaded fit between the lead screw 36 and the bolt sleeve, the loading table 33 can move up and down under the guidance of the guiding mechanism.

[0044] It should be noted that the above guiding mechanism may include a guiding rod 371 and a guiding sleeve 372. The guiding sleeve 372 is fixedly connected to the feeding table 33, and the guiding rod 371 is slidably inserted through the guiding sleeve 372. The guiding of the feeding table 33 is realized by the sliding fit between the guiding rod 371 and the guiding sleeve 372.

[0045] Of course, the above feeding driving member can also be selected as a driving cylinder, an oil cylinder, etc. in the prior art.

[0046] Furthermore, the pressing assembly 60 in this embodiment includes a pressing head 61, a pressing driving member, a lifting block, and a lifting block driving member. The pressing head and the lifting block are respectively arranged above and below the conveying assembly and are correspondingly arranged. The pressing driving member 62 is used to drive the pressing head 61 to move up and down, and the lifting block driving member is used to drive the lifting block to move up and down. In this way, when performing the pressing action, the conveying assembly 10 conveys the fan base with the wind wheel to the lower part of the pressing head 61, and at this time, the fan base with the wind wheel is located above the lifting block. The lifting block driving member drives the lifting block to jack up and support the fan base, and the pressing driving member 62 drives the pressing head 61 to move downward. During the pressing action, the pressing head and the lifting block cooperate up and down, and the wind wheel can be pressed onto the fan base, and the pressing process is stable.

[0047] It should be noted that the above pressing head 61 can be made of soft rubber material, so as to prevent the wind wheel from being damaged when pressing down. The pressing driving member 62 can be selected as a linear motion driving structure such as a cylinder or an electric slide table to achieve.

[0048] Furthermore, there are two dust suction and positioning assemblies 20. In this way, when performing dust suction and positioning, the feeding clamping member 40 can clamp the wind wheel and transfer it to the positioning shaft 22 of one of the dust suction and positioning assemblies 20 for the first positioning and dust suction, and then the transfer clamping member 50 clamps and transfers the wind wheel on the previous positioning shaft 22 for secondary positioning and dust suction, so as to improve the positioning and dust suction effects.

[0049] Furthermore, the conveying assembly 10 includes a conveyor belt, a conveyor belt driving member, and a plurality of conveying plates. The plurality of conveying plates are fixedly connected to the conveyor belt, and the conveyor belt driving member is used to drive the conveyor belt to rotate; a second positioning sensor is arranged on the conveyor belt. Specifically, the conveyor belt driving member includes a conveying motor 35 and two conveyor wheels, and the conveyor belt is synchronously wound around the two conveyor wheels. In this way, the rotation of the conveying motor 35 can drive the conveyor wheels to rotate, and then drive the conveyor belt to drive, realizing the fan bases on the plurality of conveying plates, and the fan bases are conveyed by a single large conveying plate, which is convenient for the positioning and conveying of the fan bases.

[0050] Specifically, second positioning sensors are arranged at the wind wheel feeding station and the pressing station of the conveying assembly 10, so that the movement position of the fan base can be detected, and the wind wheel can be positioned and fed and positioned and pressed.

[0051] The second positioning sensor can also be implemented by structures such as a photoelectric sensor, an infrared sensor, or a positioning fixture, etc.

[0052] Of course, the above-mentioned loading gripper 40 and transfer gripper 50 can both adopt the same structure. Taking the transfer gripper 50 as an example, the transfer gripper 50 includes a gripping claw 51, a multi-axis robot 52, and a positioning camera 53. The multi-axis robot 52 drives the gripping claw 51 to move up and down, left and right, forward and backward, and rotate. The positioning camera 53 can take pictures of the workpiece, and the multi-axis robot 52 drives the gripping claw 51 to perform picking and placing actions according to the positioning by the positioning camera 53.

[0053] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present utility model.
