Description

Technical Field

[0001] The invention relates to the technical field of axial flow fan assembly, in particular to an automatic assembly line for axial flow fans. Background Art

[0002] Axial flow fans are widely used. They are fans in which the airflow direction is in the same direction as the axis of the fan blades. For example, electric fans and air conditioner outdoor fans are fans that operate in an axial flow mode. They are called "axial flow" because the air flows parallel to the fan axis. Axial flow fans are usually used in situations where the flow rate requirements are high and the pressure requirements are low. Axial flow fans are fixed in position and can move air.

[0003] During the assembly process of the existing axial flow fan, it is necessary to go through the processes of loading, oiling, installing spring washers, installing flat washers, installing bearings, installing outer frames, installing retaining springs, performing retaining spring installation strength testing, and labeling.

[0004] The patent with publication number CN118060901A discloses an automatic assembly line for axial flow fans, including a tooling track; a positioning tooling, which is arranged on the tooling track and driven to move by the tooling track; a fan rotor feeding manipulator, which is used to grab the fan rotor from the fan rotor feeding conveyor belt and place the fan rotor on the positioning tooling; an oiling device, which is used to apply oil on the central axis of the fan rotor; a first spring washer installation device, which is used to install the spring washer on the central axis of the fan rotor; a second spring washer installation device, which is used to install the spring washer on the central axis of the fan rotor, and the second spring washer installation device The spring washer installation direction of the device is opposite to that of the first spring washer installation device; the first flat washer installation device is used to install the flat washer on the central axis of the fan rotor; the first bearing installation device is used to install the bearing on the fan rotor; the outer frame installation manipulator is used to grab the outer frame from the outer frame feeding conveyor and install the outer frame on the fan rotor; the second bearing installation device is used to install the bearing on the outer frame; the second flat washer installation device is used to install the flat washer on the central axis of the fan rotor; the retaining ring installation device is used to install the retaining ring on the central axis of the fan rotor; the unloading manipulator is used to unload the workpiece. The assembly of the axial flow fan can be completed automatically, and no human participation is required in the entire assembly process. The degree of automation is high, which greatly improves the assembly efficiency and saves labor costs.

[0005] In the above technical solution, the fan rotor loading robot is used to grab the fan rotor from the fan rotor loading conveyor and place the fan rotor on the positioning tooling. The assembly speed of the axial flow fan is much lower than the transportation speed of the fan rotor loading conveyor, resulting in the fan rotors piling up on the fan rotor loading conveyor, which can easily cause damage to the fan rotor blades. In addition, the accumulated fan rotors make it difficult for the fan rotor loading robot to position and clamp, thereby slowing down work efficiency. Therefore, an automatic assembly line for axial flow fans is urgently needed to solve the above-mentioned problems. Summary of the invention

The end face edges of the cover door 511 are respectively fixedly connected to the first arm plate 508 and the second arm plate 510.

[0097] The working principle of the present invention is as follows:

[0098] According to the specifications of the fan rotor transported by the conveyor belt 101, the height of the air cushion 209 is adjusted by the electric telescopic column 213 so that it is just on the lower side of the fan rotor blades, and the distance between the air cushions 209 on both sides is adjusted by the first cylinder 203 so that it just fits the fan rotor shell. The fan rotor is transported by the conveyor belt 101. When the fan rotor leaves the conveyor belt 101 and enters the sinking mechanism 2, the fan rotor shell is sunk between the air cushions 209 on both sides, and the fan rotor blades are overlapped on the air cushions 209, so that the support and clamp assembly can adapt and lift a single fan rotor. Through the adjustability of the sinking mechanism 2, fan rotors of various specifications can be adapted for use, thereby improving the scope of application.

[0099] The fan rotor is lifted by the contact between the air cushion 209 and the blades of the fan rotor, and the protection of the fan rotor blades is improved through soft contact.

[0100] In the early stage of operation, the position of the strip plate 212 is regulated by the second cylinder 211 so that it supports the rocker arm 113 and thus the second gear 116 and the first gear 103 are engaged. After the fan rotor is lifted by the support and clamp assembly, under the action of the gravity of the fan rotor, the support plate 208 slides down along the plate groove 205 through the slide bar 206, and the strip plate 212 slides down following the plate 210, so that the rocker arm 113 deflects around the outer axis 111, and the meshing state of the second gear 116 and the first gear 103 is released, and the conveyor belt 101 stops conveying the fan rotor. The fan rotor lifted by the support and clamp assembly of the sinking mechanism 2 waits for the mechanical arm 303 in the dispatching mechanism 3 to clamp and transport it. The shutdown of the conveyor belt 101 can save working energy and improve energy saving.

[0101] When the sinking mechanism 2 carries the fan rotor, the conveyor belt 101 can be stopped to avoid accumulation of the fan rotors on the conveyor belt 101, thereby reducing mutual contact between the fan rotors, avoiding squeezing and collision, and improving transportation safety.

[0102] The fan rotor lifted by the sinking mechanism 2 moves downward a certain distance under the action of gravity, and the fan rotor carried by the supporting clamp assembly on the sinking mechanism 2 is separately isolated and fixed at a certain height, which can facilitate the mechanical arm 303 in the dispatching mechanism 3 to locate and take the fan rotor, thereby improving work efficiency.

[0103] By setting the dust collection component, in the process of the conveyor belt 101 conveying the fan rotor, the vacuum cleaner 109 is started to vacuum and clean the fan rotor passing through the conveyor belt 101 through the dust tube 105 and the dust cover 104, thereby reducing the retention of dust. After the fan rotor is assembled, the wear between the various parts of the axial flow fan is reduced, which can extend the service life of the axial flow fan and improve the assembly quality.

[0104] When the conveyor belt 101 is running, the shaft block 506 rotates rapidly along with the front roller of the conveyor belt 101, and the airbag 507 has no time to deform, thereby driving the shaft sleeve 504 to rotate so that the first arm plate 508 approaches the second arm plate 510 to open the cover door 511, making it convenient for the fan rotor to enter the conveyor belt 101 from the inlet plate 501. When the conveyor belt 101 stops, under the tension of the second spring 509, the airbag 507 is compressed and slowly deformed, causing the shaft sleeve 504 and the shaft block 506 to rotate in an offset manner, and the first arm plate 508 gradually moves away from the second arm plate 510, causing the cover door 511 to automatically close the front port of the dust cover 104, thereby improving the degree of automation.

[0105] Under the normal operation of the conveyor belt 101, the dust hood 104 absorbs dust from the fan rotor, and wind is supplied from the front and rear ports of the dust hood 104. When the conveyor belt 101 stops operating, the hood door 511 is closed, so that the wind is only supplied from the rear port of the dust hood 104, which can further drive the internal air flow of the processing box 401, and introduce fresh air through the dust filter plate 402 to dissipate heat and clean dust inside, thereby improving the cleanliness during operation.

[0106] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
