Description

Technical Field

[0001] This invention relates to the field of automated fan assembly equipment technology, and in particular to a fully automated assembly equipment and assembly process compatible with multiple types of fans. Background Technology

[0002] With the increasing demand for heat dissipation in electronic devices, fans, as key heat dissipation components, are becoming increasingly diverse in their structural types. Currently, the most common fans on the market are mainly divided into two types: open fans and closed fans. Open fans typically include components such as fan blades, fan frame, shock-absorbing ring, shaft retaining ring, and rubber cover; closed fans typically include components such as fan blades, fan frame, cross retaining ring, and bearing, and the fan blades all need to be magnetized.

[0003] In current technology, fan assembly largely relies on manual labor or semi-automated equipment, which is inefficient and inconsistent. Although some automated assembly equipment has been put into use, these devices are usually designed for a single type of fan, such as assembling enclosed or open fans. When two different types of fans need to be assembled on the production line at the same time, companies often need to configure two separate sets of equipment, resulting in high equipment costs, large footprint, complex processes, and hindering flexible adjustments to production plans.

[0004] Furthermore, due to differences in components, the assembly processes for the two types of fans also differ. For example, enclosed fans require the installation of cross-shaped retaining rings and bearings after the fan blades are magnetized, while open fans require the installation of damping rings and bearings after the fan blades are magnetized, and further installation of another damping ring, shaft retaining rings, and rubber caps after assembly. Existing equipment struggles to achieve this switchable process flow at the same workstation, resulting in redundant production line layouts and low material handling efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automated assembly equipment and assembly process compatible with multiple types of fans. It integrates two optional assembly processes on the same workbench to achieve efficient and flexible assembly of different types of fans, thereby reducing equipment investment costs and improving the degree of automation and adaptability of production.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a fully automatic assembly device compatible with multiple types of fans, comprising a workbench, wherein the workbench is provided with:

[0007] A fan blade processing system includes a first fan blade feeding channel, a magnetization system, a first shock-absorbing ring feeding mechanism, and a second fan blade feeding channel arranged sequentially.

[0008] The fan frame processing system includes a fan frame feeding channel, a cross-ring feeding mechanism, and a bearing feeding mechanism arranged in sequence. The bearing feeding mechanism includes a bearing vibrating plate and a material separating mechanism. A material passage for guiding the bearing is provided between the bearing vibrating plate and the material separating mechanism. The material separating mechanism includes a movable table connected to the material passage and a bearing drive mechanism that is connected to the movable table. The bearing drive mechanism drives the movable table to displace the bearing on the movable table away from the material passage.

[0009] The fan blade and frame assembly mechanism is connected between the fan blade processing system and the fan frame processing system. It picks up the fan blades on the second fan blade feeding channel and moves the fan blades to the fan frame on the fan frame feeding channel for assembly, forming the fan body.

[0010] The fan body processing system includes a second shock-absorbing ring feeding mechanism, a shaft retaining ring feeding mechanism, a rubber cover feeding mechanism, and a label feeding mechanism;

[0011] The equipment is configured to perform two assembly processes on the same workbench:

[0012] The first assembly process sequentially passes through the magnetization system, the cross-ring feeding mechanism, the bearing feeding mechanism, the fan blade and frame assembly mechanism, and the label feeding mechanism to form a closed fan product.

[0013] The second assembly process sequentially passes through the magnetization system, the first shock-absorbing ring feeding mechanism, the bearing feeding mechanism, the fan blade and frame assembly mechanism, the second shock-absorbing ring feeding mechanism, the shaft retaining ring feeding mechanism, the rubber cover feeding mechanism, and the label feeding mechanism to form an open-type fan product.

The first damping ring feeding mechanism is located between the magnetic ring pressing mechanism and the fan blade flipping mechanism.

A material separating groove for accommodating the bearing is opened on the movable table. The material separating groove is coaxially aligned with the material feeding tube in the vertical direction. The material feeding mechanism includes a pushing member and a material feeding drive mechanism connected to the pushing member. The material feeding drive mechanism drives the pushing member to push towards the discharge end of the material feeding tube, so that the bearing falling from the material feeding tube is straightened and falls into the material separating groove.

[0022] A further configuration of the present invention is as follows: the bearing loading mechanism further includes a bearing clamping mechanism, the bearing clamping mechanism including a bearing clamping base disposed on the worktable, and a first bearing clamping drive mechanism and a first bearing clamping sliding plate disposed on the bearing clamping base.

[0025] The label feeding mechanism includes a label feeding bracket, and a reel, a roller assembly, and a take-up roller mounted on the label feeding bracket. A movable bracket is slidably connected to the label feeding bracket, and a first label feeding drive mechanism is fixedly connected and driven by the movable bracket.

The second label feeding drive mechanism drives the third suction head to reciprocate along the Z-axis. The first label feeding drive mechanism and the second label feeding drive mechanism cooperate to adsorb and stick the labels on the conveyor belt on the movable bracket to the fan body at the corresponding workstation via the third suction head.

[0026] A further feature of the present invention is that the first fan blade feeding channel, the second fan blade feeding channel, and the fan frame feeding channel each include two parallel guide rails extending along the X-axis direction. The guide rails on the first fan blade feeding channel, the second fan blade feeding channel, and the fan frame feeding channel are all connected to an adjustment mechanism, which drives the guide rails to move toward each other or toward each other.

[0065] In summary, the present invention has the following beneficial effects:

[0066] 1. The equipment employs a workbench equipped with a fan blade processing system, a fan frame processing system, a fan blade and fan frame assembly mechanism, and a fan body processing system. The equipment is configured to execute two assembly processes on the same workbench: the first assembly process sequentially passes through a magnetization system, a cross-ring feeding mechanism, a bearing feeding mechanism, a fan blade and fan frame assembly mechanism, and a label feeding mechanism to form a closed fan product; the second assembly process sequentially passes through a magnetization system, a first shock-absorbing ring feeding mechanism, a bearing feeding mechanism, a fan blade and fan frame assembly mechanism, a second shock-absorbing ring feeding mechanism, a shaft ring feeding mechanism, a rubber cap feeding mechanism, and a label feeding mechanism to form an open fan product. Integrating two selectable assembly processes on the same workbench enables efficient and flexible assembly of different types of fans, reducing equipment investment costs and improving production automation and adaptability.

[0067] 2. The first shock-absorbing ring loading mechanism includes a first shock-absorbing ring loading base mounted on a workbench, and a shock-absorbing ring Y-axis drive mechanism and a shock-absorbing ring loading sliding plate mounted on the first shock-absorbing ring loading base. The shock-absorbing ring Y-axis drive mechanism drives the shock-absorbing ring loading sliding plate to reciprocate along the Y-axis direction. A shock-absorbing ring Z-axis drive mechanism is mounted on the shock-absorbing ring loading sliding plate. The output end of the shock-absorbing ring Z-axis drive mechanism is connected to an elastic ejector pin. The shock-absorbing ring Z-axis drive mechanism drives the elastic ejector pin to reciprocate along the Z-axis direction, realizing the automatic picking, placing, and assembly of the first shock-absorbing ring from the first shock-absorbing ring vibrating plate to the corresponding workstation. The design of the elastic ejector pin not only realizes the gripping and releasing of the first shock-absorbing ring, but also effectively avoids damage to the first shock-absorbing ring, improving the smoothness of loading.

[0068] 3. The material separating and cutting mechanism also includes a material separating and cutting base fixedly installed on the worktable, and a mating block and a material feeding mechanism fixedly installed on the material separating and cutting base. The mating block abuts against the movable table, and a material passage pipe is provided through the mating block. The material passage pipe forms part of the material passage channel. A material separating groove for accommodating bearings is opened on the movable table. The material separating groove is coaxially aligned with the material passage pipe in the vertical direction. The material feeding mechanism includes a pushing member and a material feeding drive mechanism connected to the pushing member. The material feeding drive mechanism drives the pushing member to push towards the discharge end of the material passage pipe, so that the bearing falling from the material passage pipe is corrected and falls into the material separating groove. It can actively intervene in the bearing falling from the material passage pipe. When the bearing falls in an incorrect posture, the pushing member can correct it in time to ensure that the bearing falls into the material separating groove below in the correct posture. This effectively solves the problem of bearing posture disorder caused by vibration or friction and ensures the consistency and reliability of the material separating process.

[0069] 4. The fan blade and frame assembly mechanism includes an assembly and feeding base mounted on a workbench, and a first assembly and feeding sliding plate slidably connected to the assembly and feeding base. A first assembly and feeding drive mechanism is driven to the first assembly and feeding sliding plate, which drives the first assembly and feeding sliding plate to reciprocate along the Y-axis between the second fan blade feeding channel and the fan frame feeding channel. A second assembly and feeding sliding plate and a third assembly and feeding sliding plate are slidably connected to the first assembly and feeding sliding plate, and a second assembly and feeding drive mechanism is driven to the second assembly and feeding sliding plate and a third assembly and feeding drive mechanism is driven to the third assembly and feeding sliding plate, respectively. A first suction head is provided on the second assembly and feeding sliding plate, and the second assembly and feeding drive mechanism drives the second assembly and feeding sliding plate to reciprocate along the Z-axis. A second suction head is provided on the third assembly and feeding sliding plate, and the third assembly and feeding drive mechanism drives the third assembly and feeding sliding plate. A loading sliding plate causes the second adsorption head to reciprocate along the Z-axis. A transfer station is set between the second fan blade feeding channel and the fan frame feeding channel, and a photoelectric sensor corresponding to the position of the transfer station is set on the worktable. The first assembly loading drive mechanism, the second assembly loading drive mechanism, and the third assembly loading drive mechanism work together to transfer the fan blades on the second fan blade feeding channel to the transfer station through the second adsorption head, and transfer the fan blades on the transfer station to the corresponding station through the first adsorption head. By setting the transfer station and the second adsorption head, the "pre-picking" function of the fan blades is realized. When the assembly station is performing the pressing action of the previous fan blade, the second adsorption head can simultaneously grab the next fan blade from the fan blade channel and place it in the transfer station to wait. In this way, when the previous pressing action is completed, the first adsorption head can immediately take the prepared fan blade from the transfer station for the next assembly, eliminating the waiting time for picking up materials and effectively improving the overall production cycle.

[0085] The invention will now be further described with reference to the accompanying drawings.

[0086] A fully automated assembly device compatible with multiple types of fans, such as Figure 1-14 As shown, it includes a workbench 1, on which the following are provided:

[0087] The fan blade processing system includes a fan blade clamping mechanism 25, a first fan blade feeding channel 21, a second fan blade feeding channel 24, and a magnetic ring pressing mechanism, a first damping ring feeding mechanism, and a fan blade flipping mechanism arranged sequentially along the assembly process. The workbench 1 has several stations corresponding to the positions of the magnetic ring pressing mechanism, the first damping ring feeding mechanism, and the fan blade flipping mechanism. The fan blade clamping mechanism 25 drives the fan blades on the first fan blade feeding channel 21 to sequentially pass through the stations corresponding to the magnetic ring pressing mechanism, the first damping ring feeding mechanism, and the fan blade flipping mechanism, and then transfers them to the second fan blade feeding channel 24. The holding mechanism 25 is existing technology and will not be described in detail here; any device capable of driving the fan blades to move at each workstation is acceptable. The magnetic ring pressing mechanism is existing technology and will not be described in detail here; any device capable of pressing the magnetic strip against the fan blades is acceptable. The fan blade flipping mechanism is a flipping cylinder, which is existing technology and will not be described in detail here. The first damping ring feeding mechanism includes a first damping ring vibrating plate 231, a first damping ring loading mechanism, and a first damping ring pressing detection mechanism 233. The first damping ring pressing detection mechanism 233 includes a detection base mounted on the workbench 1, a detection drive mechanism mounted on the detection base, and a drive mechanism connected to the detection base. The detection device of the drive mechanism is a probe integrating a pressure sensor. The detection device is equipped with a hollow pressure head, the inner diameter of which is slightly larger than the outer diameter of the fan blade's central shaft. When the fan blade reaches the designated position, the drive mechanism drives the hollow pressure head downwards, causing its annular end face to smoothly press against the upper surface of the shock-absorbing ring. The pressure sensor acquires the pressure value, and the pressure value is used to determine whether the shock-absorbing ring exists or whether it is installed evenly. The first shock-absorbing ring loading mechanism includes a first shock-absorbing ring loading base 2321 mounted on the workbench 1, and a shock-absorbing ring Y-axis drive mechanism 2322 and a damping ring loading mechanism mounted on the first shock-absorbing ring loading base 2321. The shock-absorbing ring loading sliding plate 2323 and the shock-absorbing ring Y-axis drive mechanism 2322 are cylinders. The shock-absorbing ring Y-axis drive mechanism 2322 drives the shock-absorbing ring loading sliding plate 2323 to reciprocate along the Y-axis direction. The shock-absorbing ring loading sliding plate 2323 is provided with a shock-absorbing ring Z-axis drive mechanism 2324, which is a cylinder. The output end of the shock-absorbing ring Z-axis drive mechanism 2324 is connected to an elastic ejector pin 2325. The elastic ejector pin 2325 consists of an outer tube, a central rod that can slide inside the outer tube, and a compression spring sleeved on the central rod. The lower end of the central rod is a conical or hemispherical guide head.The Z-axis drive mechanism 2324 of the shock-absorbing ring drives the elastic pin 2325 to reciprocate along the Z-axis. A through hole is provided at the outlet end of the first shock-absorbing ring vibrating disk 231, allowing the elastic pin 2325 to pass through. The first shock-absorbing ring is located on the end face of the through hole. When the shock-absorbing ring loading sliding plate 2323 moves above the outlet of the first shock-absorbing ring vibrating disk 231, the Z-axis drive mechanism 2324 drives the elastic pin 2325 to descend. The elastic pin 2325 inserts into the inner hole of the first shock-absorbing ring fed out by the first shock-absorbing ring vibrating disk 231 and passes through the through hole. The friction of the first shock-absorbing ring... Under the action of the spring, the elastic ejector pin 2325 is inserted, and then the damping ring loading sliding plate 2323 moves to the corresponding station. The damping ring Y-axis drive mechanism 2322 drives the elastic ejector pin 2325 to descend again. The lower end of the central rod of the elastic ejector pin 2325 abuts against the rod on the central shaft of the fan blade. Under continuous downward pressure, the central rod of the elastic ejector pin 2325 overcomes the force of the compression spring and contracts relative to the outer sleeve. The first damping ring descends and naturally falls onto the rod on the central shaft of the fan blade. Finally, the elastic ejector pin 2325 rises, and the compression spring resets the central rod, completing one loading cycle. Through the above structural design, the automatic picking and placing and assembly of the first damping ring from the first damping ring vibrating plate 231 to the corresponding station is realized. The design of the elastic ejector pin 2325 not only realizes the gripping and releasing of the first damping ring, but also effectively avoids damage to the first damping ring, improving the smoothness of loading.

The material separating mechanism includes a movable table 3321 and a bearing drive mechanism 3322 that is pulsatorically connected to the movable table 3321.

The material feeding drive mechanism 3328 is... The cylinder, the feeding drive mechanism 3328 drives the actuating member 3327 towards the discharge end of the feed pipe 3325, so that the bearing falling from the feed pipe 3325 is corrected and falls into the distribution groove 3326. By setting the actuating member 3327 and the feeding drive mechanism 3328, the bearing falling from the feed pipe 3325 can be actively intervened. When the bearing falls incorrectly (such as tilting or falling), the actuating member 3327 can correct it in time, ensuring that the bearing falls smoothly into the distribution groove 3326 below in the correct posture (vertical state). This effectively solves the problem of bearing posture disorder caused by vibration or friction, and ensures the consistency and reliability of the distribution process.

The first bearing clamping drive mechanism 3332, the second bearing clamping drive mechanism 3334, and the third bearing clamping drive mechanism 3336 work together to drive the bearing clamping block 3337 to clamp the bearing on the material distribution groove 3326 and transfer it to the corresponding work station. Through the above structural design, the entire process of bearing from material distribution to transfer is automated without manual intervention, which improves production efficiency and ensures the consistency of the transfer process.

[0089] The fan blade and frame assembly mechanism includes an assembly loading base 41 disposed on the workbench 1, and a first assembly loading sliding plate 42 slidably connected to the assembly loading base 41. A first assembly loading drive mechanism 43, which is a cylinder, is driven to the first assembly loading sliding plate 42 to reciprocate along the Y-axis between the second fan blade feeding channel 24 and the fan frame feeding channel 31. A second assembly loading sliding plate 44 and a third assembly loading sliding plate 45 are slidably connected to the first assembly loading sliding plate 42, and a second assembly loading drive mechanism 46 and a third assembly loading drive mechanism 47 are respectively driven to the second assembly loading sliding plate 44 and the third assembly loading sliding plate 45. The third assembly feeding drive mechanism 47 is a cylinder. The second assembly feeding sliding plate 44 is provided with a first suction head 48, which is a vacuum nozzle. The second assembly feeding drive mechanism 46 drives the second assembly feeding sliding plate 44, causing the first suction head 48 to reciprocate along the Z-axis. The third assembly feeding sliding plate 45 is provided with a second suction head 49, which is a vacuum nozzle. The third assembly feeding drive mechanism 47 drives the third assembly feeding sliding plate 45, causing the second suction head 49 to reciprocate along the Z-axis. A transfer station 410 is provided between the second fan blade feeding channel 24 and the fan frame feeding channel 31. The workbench 1 is provided with a photoelectric sensor 411 corresponding to the position of the transfer station 410. The photoelectric sensor 411 is used to detect whether the fan blade on the transfer station 410 has been placed in place.The first assembly loading drive mechanism 43, the second assembly loading drive mechanism 46, and the third assembly loading drive mechanism 47 cooperate to transfer the fan blades on the second fan blade feeding channel 24 to the transfer station 410 via the second suction head 49, and transfer the fan blades on the transfer station 410 to the corresponding station via the first suction head 48. The specific collaborative workflow is as follows: First, the first assembly loading drive mechanism 43 drives the first assembly loading sliding plate 42 to move above the second fan blade feeding channel 24; the third assembly loading drive mechanism 47 drives the second suction head 49 to descend and pick up a fan blade. Then, the first assembly loading drive mechanism 43 drives the third assembly loading sliding plate 45 to move above the transfer station 410; the third assembly loading drive mechanism 47 descends and places the fan blade in the transfer station 410. The photoelectric sensor 411 detects… After the fan blade is placed in position, the second assembly feeding drive mechanism 46 drives the first suction head 48 on it to descend and pick up the fan blade from the transfer station 410. Finally, the first assembly feeding drive mechanism 43 drives the first assembly feeding sliding plate 42 to move to the assembly station, and the second drive mechanism drives the first suction head 48 to descend, completing the final pressing assembly of the fan blade and the fan frame. By setting the transfer station 410 and the second suction head 49, the "pre-picking" function of the fan blade is realized. When the assembly station is performing the pressing action of the previous fan blade, the second suction head 49 can simultaneously go to the fan blade channel to grab the next fan blade and place it in the transfer station 410 to wait. In this way, when the previous pressing action is completed, the first suction head 48 can immediately take the prepared fan blade from the transfer station 410 for the next assembly, eliminating the waiting time for picking up materials and effectively improving the overall production cycle.

The pull-out detection drive mechanism is a servo electric cylinder with an integrated force sensor. The pull-out detection drive mechanism drives the suction cup to move towards or away from the corresponding work position of the fan body. When the fan body reaches the corresponding work position and is positioned, the pull-out detection drive mechanism drives the suction cup to move towards the fan body, directly... The suction cup contacts and adheres to the center area of ​​the fan blade. Then, the pull detection drive mechanism applies a uniform pulling force away from the fan frame. At the same time, the force sensor integrated in the pull detection drive mechanism monitors the pulling force value in real time. The assembly and detection station is also equipped with a displacement sensor, which monitors the displacement. By comparing the force-displacement curve during the pull process with a preset standard curve or threshold, it is determined whether the bonding force between the fan blade and the shaft is qualified. The unqualified products detected on the fan frame feeding channel 31 are discharged through the defective product discharge mechanism 59.

The first label feeding drive mechanism 546 drives the movable bracket 545 to move closer to the third suction head 548 and aligns the label with the third suction head 548 coaxially. Then, the second label feeding drive mechanism 547 drives the third suction head 548 to descend and pick up the label above the movable bracket 545. Then, the first label feeding drive mechanism 546 drives the movable bracket 545 to reset, and the take-up roller 544 moves synchronously to rewind the conveyor belt.

[0091] The equipment is configured to perform two assembly processes on the same workbench 1:

[0092] The first assembly process sequentially passes through the magnetization system 6, the cross-ring feeding mechanism, the bearing feeding mechanism, the fan blade and frame assembly mechanism, and the label feeding mechanism to form a closed fan product.

[0093] The second assembly process sequentially passes through the magnetization system 6, the first shock-absorbing ring feeding mechanism, the bearing feeding mechanism, the fan blade and frame assembly mechanism, the second shock-absorbing ring feeding mechanism, the shaft retaining ring feeding mechanism, the rubber cover feeding mechanism, and the label feeding mechanism to form an open fan product.

[0094] Preferably, the magnetization system 6 is located upstream of the first fan blade feeding channel 21, and includes a stacking mechanism disposed on the workbench 1. The stacking mechanism includes a stacking bin 2211 storing multiple magnetic strips, and a first magnetic strip pushing mechanism and a discharge chute 223 respectively located on both sides of the stacking bin 2211. The magnetic strips are long and are stacked horizontally in the stacking bin 2211. The first magnetic strip pushing mechanism includes a first magnetic strip driving mechanism 2221 and a first magnetic strip pushing plate 2222 driven by the first magnetic strip driving mechanism 2221. The first magnetic strip driving mechanism 2221 is a cylinder. The first magnetic strip driving mechanism 2221 drives the first magnetic strip pushing plate 2222 to push the magnetic strips in the stacking bin 2211 one by one into the discharge chute 223.

[0095] The magnetization system 6 further includes a second magnetic stripe pushing mechanism and a winding mechanism 225. The second magnetic stripe pushing mechanism includes a second magnetic stripe driving mechanism 2241 and a second magnetic stripe pusher plate 2242 connected to the output end of the second magnetic stripe driving mechanism 2241. The second magnetic stripe driving mechanism 2241 is a cylinder. The second magnetic stripe pusher plate 2242 and the winding mechanism 225 are located at two opposite ends of the material drop trough 223, respectively. The second magnetic stripe driving mechanism 2241 drives the second magnetic stripe pusher plate 2242 to push the magnetic stripe in the material drop trough 223 into the winding mechanism 225 for winding.

[0096] The magnetization system 6 also includes a magnetic strip feeding mechanism and a magnetic strip pressing mechanism. The magnetic strip feeding mechanism is used to convey the ring body, and the magnetic strip pressing mechanism is arranged on the conveying path of the magnetic strip feeding mechanism. It is used to press the magnetic strip wound by the winding mechanism 225 with the ring body conveyed by the magnetic strip feeding mechanism to form a magnetic ring. The magnetic strip feeding mechanism and the magnetic strip pressing mechanism are existing technologies and will not be described in detail here.

[0097] The magnetization system 6 also includes a magnetization mechanism 228, located at the end of the conveying path of the magnetic strip feeding mechanism. The magnetization mechanism 228 contains a magnetization coil and a circuit control unit. When the assembled magnetic ring is conveyed to the station of the magnetization mechanism 228 by the feeding mechanism, the magnetization mechanism 228 is activated, generating a powerful pulsed magnetic field to magnetize the magnetic ring, enabling it to acquire the required magnetic poles. This achieves continuous operation throughout the entire process, from automatic magnetic strip feeding and winding to automatic pressing with the ring body and finally magnetization, constructing a complete automated production line. This changes the traditional cumbersome mode of relying on manual operation, improves production efficiency and product consistency, and reduces labor costs and labor intensity.

[0098] Preferably, the first fan blade feeding channel 21, the second fan blade feeding channel 24, and the fan frame feeding channel 31 each include two parallel guide rails 10 extending along the X-axis. The guide rails 10 on the first fan blade feeding channel 21, the second fan blade feeding channel 24, and the fan frame feeding channel 31 are all connected to an adjustment mechanism. The adjustment mechanism is a screw structure driven by a motor. The adjustment mechanism drives the guide rails 10 to move in a direction that is closer to or further away from each other. By operating the adjustment mechanism, one or a pair of guide rails 10 can be driven to move synchronously in the Y-axis direction (i.e., the direction of the spacing between the guide rails 10), thereby changing the guide width between the two guide rails 10, thus adapting to and processing various fan frame or fan blade products of different shapes and sizes, significantly expanding the application range of the equipment.

[0099] It should be noted that the X-axis direction mentioned above is the main direction of conveying the fan frame and fan blades, that is, the direction in which the first fan blade feeding channel 21, the second fan blade feeding channel 24, and the fan frame feeding channel 31 are set; the Y-axis direction is the horizontal conveying direction perpendicular to the fan frame and fan blades; and the Z-axis direction is the vertical conveying direction perpendicular to the fan frame and fan blades.
