Description

Technical Field

[0001] The present invention relates to the technical field of fan blade balance testing, and in particular to a fan blade balance cutting device. Background Art

[0002] As a key component for enhancing driving comfort, the turbine blades used in automotive seat ventilation must achieve efficient airflow and low-noise operation within a confined space. Their dynamic balance performance directly impacts the stability of the seat ventilation system and the user's perceived quality. With the increasing demand for quietness in the cabin of new energy vehicles, the dynamic balance correction accuracy of the turbine blades must reach the milligram level. However, micron-level debris left over from cutting (especially debris from lightweight materials such as polypropylene and nylon) can introduce vibration and noise sources, leading to errors in dynamic balance detection and, in turn, abnormal airflow noise. Furthermore, the seat ventilation module must adapt to complex curved surfaces and porous structures. Traditional dust removal technologies struggle to completely remove electrostatically adsorbed debris from hidden areas such as the blade roots and curved grooves, severely restricting the yield rate and production efficiency of high-end models.

[0003] Currently, high-pressure pulsed air-blowing dust removal solutions are commonly used in automobile seat turbine blade balancing and cutting devices. For example, the blade surface is blown in a targeted manner through an annular array nozzle. Although this can remove some surface dust, it is poor at removing debris from complex structures such as blade root grooves and micro-guide holes, and is almost ineffective against sub-millimeter plastic debris adsorbed by electrostatics. In order to meet the cleaning standards, the air blowing pressure needs to be increased, resulting in increased energy consumption per piece, and high air pressure can easily cause lightweight blades to deform. Simply relying on airflow kinetic energy cannot break through complex geometric limitations (i.e., the complex slot direction of the turbine). Forcibly improving the cleanliness requires sacrificing energy efficiency and workpiece integrity, which directly limits the large-scale and efficient production of automobile seat ventilation blades.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work shall fall within the scope of protection of the present invention.

[0019] See also Figures 1 to 8 The present invention provides a technical solution: a cutting device, which is specifically used for cutting fan blades and performing dynamic balance detection simultaneously, and performing secondary cutting according to the dynamic balance detection results, thereby ensuring the use effect of the fan blades. More specifically, the cut fan blades are used for a turbofan for ventilation of automobile seats, that is, the turbofan drives the fan blades to cut, thereby improving the dust removal effect and efficiency without adjusting the air blowing pressure.

[0020] See also Figures 1 to 8 , the present invention provides a technical solution: a fan blade balancing cutting device, including a rotating component 10, a cutting component 20 and a dust removal component 30; The rotary assembly 10 includes a rotary mechanism 12 with a carrying space 11. The carrying space 11 is used to place fan blades. The rotary mechanism 12 is used to transport the fan blades on the carrying space 11 along the rotating direction and sequentially pass through the cutting assembly 20 and the dust removal assembly 30. The cutting assembly 20 is used to cut the fan blades placed in the carrying space 11; The dust removal assembly 30 includes a closing mechanism 31, a vibrating mechanism 32, and an air intake mechanism 33. The closing mechanism 31 is used to abut the rotating mechanism 12 to close the carrying space 11. The vibrating mechanism 32 is arranged in the closing mechanism 31, and its output end abuts against the fan blades. The air intake mechanism 33 is arranged on the closing mechanism 31 and is used to send external air into the closing mechanism 31. The closing mechanism 31 is provided with an exhaust pipe 314 for discharging dust and the incoming air. The rotary mechanism 12 carries the fan blades through the opening of the carrying space 11 (it is not fixedly installed and has no limited structure. A pressing structure is provided on the cutting assembly 20. Before cutting, the pressing structure on the cutting assembly 20 first contacts the fan blades and then presses and fixes them. This is a known technology and is only cited here). The fan blades are transported to the cutting station and the dust removal station in sequence along the rotation direction (such as clockwise or counterclockwise). The closed-loop design of the rotary mechanism 12 supports continuous processing of batch fan blades. The cutting assembly 20 uses a T-type milling cutter to cut the unbalanced area of ​​the fan blades. Cutting and removing excess counterweight are existing well-known technologies and are only used for reference. The closing mechanism 31 abuts against the rotary mechanism 12 through its end to form a closed cavity to prevent debris from overflowing and external dust from invading the carrying space 11. A silicone sealing ring can be used. That is, a silicone sealing ring is provided between the rotary mechanism 12 and the closing mechanism 31. The vibration mechanism 32 generates vibration and transmits it to the fan blades. The output end of the air intake mechanism 33 injects external gas into the closing mechanism 31 at a positive pressure. The incoming gas is discharged together with the dust through the exhaust pipe 314. When the fan blade moves to the position of the cutting assembly 20 along with the rotating mechanism 12, the cutting assembly 20 cuts the fan blade placed in the carrying space 11. After the cutting assembly 20 finishes cutting, the fan blade and the carrying space 11 will leave the cut debris (i.e., waste chips). Then the rotating mechanism 12 continues to transport and transports the fan blade to the position of the dust removal assembly 30. The closing mechanism 31 first contacts the rotating mechanism 12 to close the carrying space 11. Then, the air intake mechanism 33 is used to transport positive pressure gas into the closing mechanism 31 to blow the fan blade. During the blowing process, the vibration mechanism 32 generates vibration and transmits it to the fan. On the blades, the fan blades vibrate with the transmission of vibration, and the dust and debris (i.e., waste debris) on the fan blades are shaken off to remove residual debris from complex structures such as the blade surface, grooves and shaft holes, so that the dust and debris are discharged through the exhaust pipe 314 along with the positive pressure gas. The setting of the vibration mechanism 32 can prevent dust or debris from adhering to the fan blades, and also avoid dust residue in places where the positive pressure airflow cannot blow. At the same time, the time used for dust removal is reduced without changing the airflow speed, which can effectively improve the dust removal effect while also improving the dust removal efficiency, and also reduce the blowing time of the airflow, further reducing energy loss.

[0021] In this embodiment, as a preferred embodiment, the vibration mechanism 32 includes a vibration generating portion 321 and an airflow recirculation portion 322 fixedly connected to the sealing mechanism 31. The vibration generating portion 321 is at least partially located within the airflow recirculation portion 322 and is used to generate vibration and transmit it to the airflow recirculation portion 322. One end of the airflow recirculation portion 322 abuts the fan blades and is used to transmit the vibration to the fan blades. The end of the airflow recirculation portion 322 facing away from the fan blades is at least partially located within the output end of the air intake mechanism 33 and is arranged in a frustum shape along the air intake mechanism 33 toward the fan blades. The vibration generating portion 321 is used to generate vibration, which is transmitted to the airflow recirculation portion 322. The vibration is then transmitted to the fan blades through the airflow recirculation portion 322, causing the fan blades to vibrate and shake off dust, thereby improving the dust removal effect and efficiency. At the same time, the large end of the airflow recirculation portion 322 is close to the fan blades, and the small end (the sharp end) is directed toward the air inlet mechanism 33, forming a tapered channel with the closing mechanism 31. That is, the opening size of the gas flow channel is reduced, so that the flow rate of the gas contacting the fan blades is accelerated, the impact force of the airflow is increased, and the dust is blocked to prevent dust from flowing back through the gas flow channel. Furthermore, a plurality of wavy baffles can be provided in the gap between the outer surface of the airflow recirculation portion 322 and the output end of the air intake mechanism 33 along the extension direction of the airflow recirculation portion 322, so that the airflow flows out through the gap between the baffles. The baffles reduce the boundary layer of the airflow, further preventing dust from flowing back through the boundary layer, and at the same time can also cause the airflow to generate certain vortices, further improving the efficiency and effect of dust removal.

[0022] In this embodiment, as a preferred solution, the airflow resistance part 322 includes a resistance shell 3221, an adjustment connecting rod 3222 and a pre-recognition ring 3223. The vibration generating part 321 is at least partially located in the resistance shell 3221. The end of the resistance shell 3221 away from the fan blade is at least partially located in the output end of the air intake mechanism 33, and is arranged in a cone shape along the air intake mechanism 33 toward the fan blade. The end of the resistance shell 3221 away from the air intake mechanism 33 is connected to the pre-recognition ring 3223 through the adjustment connecting rod 3222. The pre-recognition ring 3223 abuts against the fan blade. When the airflow passes through the outer surface of the cone, the cross-sectional area gradually shrinks (large end → small end). End), the flow rate gradually increases to form high-speed laminar flow, which improves the coverage effect of the airflow on the curved surface and grooves of the fan blades. The vibration energy in the return shell 3221 is transferred to the pre-recognition ring 3223 by adjusting the connecting rod 3222, and the pre-recognition ring 3223 is continuously pressed against the fan blades through the telescopic characteristics, thereby performing stable vibration energy transmission. The pre-recognition ring 3223 is in contact with the fan blades, not only to transmit vibration energy, but also to press the fan blades to avoid tilting or displacement caused by the airflow, which affects the subsequent robot grasping, or other blanking structures to position and blank. The blanking structure is a well-known technology and can be a four-axis blanking robot.

[0023] The locking cam 32223 is fixed to the locking cam 32221 and is secured to the locking cam 32222 by the spring 32224. The locking cam 32223 is secured to the locking cam 32222 by the spring 32224. 22 only moves along the axial direction to avoid lateral displacement and thus dispersion of vibration energy. The outer rod 32221 is made of carbon fiber composite material, which has improved bending strength compared to aluminum alloy, thus avoiding structural resonance under high-frequency vibration. The inner rod 32222 slides axially in the outer rod 32221, and automatically adjusts the extension length according to the thickness of the fan blade. The end of the inner rod 32222 is connected to the pre-recognition ring 3223, which transmits the vibration energy of the return shell 3221 to the surface of the fan blade. The disc spring 32223 pushes the inner rod 32222 to extend with a constant axial force, ensuring stable contact between the pre-recognition ring 3223 and the fan blade. The spring preload force of the disc spring 32223 eliminates mechanical clearance and avoids energy loss during vibration transmission. The disc spring 32223 only buffers axial impact and does not absorb lateral vibration energy. The coil spring will absorb lateral vibration energy and affect the transmission of vibration energy.

[0024] In this embodiment, as a preferred solution, the vibration generating portion 321 includes a power shaft 3212 and a plurality of vibration springs 3211. The plurality of vibration springs 3211 are circumferentially arranged within the airflow resistance portion 322. The power shaft 3212 is at least partially located within the airflow resistance portion 322, and a paddle 3213 is fixedly connected to the outer surface of the power shaft 3212. The paddle 3213 is located within the airflow resistance portion 322, and one end of the paddle 3213 at least partially overlaps with one end of the vibration spring 3211 along the rotation direction of the power shaft 3212. The power shaft 3212 is driven by a motor or a transmission system to provide periodic rotational motion. A plurality of paddles 3213 (6-12 pieces) are fixed on the outer surface of the power shaft 3212. The vibration shrapnel 3211 is periodically triggered by the rotational motion. Specifically, the paddle 3213 touches one end of the vibration shrapnel 3211 and then leaves. The vibration shrapnel 3211 is elastically deformed by the touch of the paddle 3213. Then, after the paddle 3213 leaves, the vibration shrapnel 3211 resets to generate elastic vibration, thereby forming a mechanical pulse vibration. A plurality of shrapnel (such as 8 pieces) are arranged in a circular array along the inner wall of the airflow resistance part 322 with equal spacing to ensure that the vibration energy is evenly distributed. The paddle 3213 periodically strikes the free end of the shrapnel, stimulating the bending vibration of the shrapnel and generating mechanical shock wave vibration energy. The root of the shrapnel is fixed to the inner wall of the return shell 3221, and the vibration energy is transmitted to the pre-recoil ring 3223 and the fan blades through the return shell 3221. The overlapping length between the end of the paddle 3213 and the free end of the shrapnel is adjustable to control the impact contact area and action time. Multiple paddles 3213 and shrapnel are arranged at a specific phase angle (such as 45° intervals) to form a continuous vibration wave to avoid excessive energy pulse intervals. The impact surface of the paddle 3213 is inlaid with hard alloy (such as tungsten carbide), and the contact end of the shrapnel is covered with a polyurethane buffer layer to increase service life.

[0025] In this embodiment, as a preferred solution, the air intake mechanism 33 includes an air intake cover 333, an air intake blade 331 and a drive shaft 332. The air intake cover 333 is fixedly connected to the closing mechanism 31, and the air outlet end is located in the closing mechanism 31. The drive shaft 332 is at least partially located in the air intake cover 333. One end of the drive shaft 332 is connected to the driving member. The air intake blade 331 is arranged on the outer surface of the drive shaft 332 and is located in the air intake cover 333. The end of the power shaft 3212 located outside the air flow resistance part 322 is arranged on the end of the drive shaft 332 located in the air intake cover 333. 33 is fixed on the closing mechanism 31 to introduce external air into the closed space. The air intake hood 333 and the closing mechanism 31 interface are connected by a silicone sealing ring to prevent air flow overflow and external dust intrusion. The driving member is a well-known technology and can be a motor. The purpose is to drive the driving shaft 332 to rotate. Through the connection between the driving shaft 332 and the power shaft 3212, the driving shaft 332 can drive the power shaft 3212 to rotate, reducing the use of the power source. At the same time, the driving shaft 332 drives the air intake blades 331 to rotate to generate airflow, and the outside air is sent into the closed space through the air intake hood 333.

The closed cover 311 and the lower closed cover 312 are both set on a lifting frame, which is provided with a guide rail. Two sliding blocks are arranged opposite to each other on the guide rail. The upper closed cover 311 is set on one of the sliding blocks, and the lower closed cover 312 is set on the other sliding block. The upper closed cover 311 and the lower closed cover 312 are moved towards each other by controlling the movement of the two sliding blocks. The lifting frame, guide rail and sliding blocks are all existing technologies and are only used for reference here. It can also be that two hydraulic telescopic rods are respectively connected to the upper closed cover 311 and the lower closed cover 312 to push the upper closed cover 311 and the lower closed cover 312 to move towards each other.

[0027] In this embodiment, as a preferred solution, the rotating mechanism 12 includes a rotating disk 121, a mounting disk 122 and a carrying disk 123. A plurality of mounting positions are provided on the rotating disk 121. The number of the mounting disk 122 and the carrying disk 123 corresponds to the mounting positions. The mounting disk 122 is correspondingly mounted on the mounting position by bolts. The carrying disk 123 is slidably connected in the mounting disk 122. The carrying space 11 is provided on the surface of the carrying disk 123. The rotating disk 121 can rotate. There are multiple mounting positions and can work continuously. That is, the cutting work and the dust removal work can be carried out at the same time. Further, dynamic balancing detection and unloading can be carried out synchronously. That is, multiple workstations work at the same time, rotate uniformly, and can work continuously. Through the connection between the mounting disk 122 and the carrying disk 123, the carrying disk 123 can slide in the mounting disk 122. At the same time, the rotating disk 121 is connected to the output end of the servo motor. The servo motor drives the rotating disk 121 to rotate indexed.

Please refer to the following for details: Figures 4 and 5 The mounting plate 122 is slidably connected to the sleeve rod 134, that is, the sleeve rod 134 is provided with a first position and a second position. When the sleeve rod 134 is set to the first position, the return spring 136 is relatively extended. At this time, one end of the sleeve rod 134 located in the mounting plate 122 abuts against the lower surface of the carrier plate 123, and the other end of the sleeve rod 134 is away from the upper surface of the mounting plate 122. The telescopic end of the locking rod 133 presses the carrier plate 123 tightly. The fixed end of the locking rod 133 is set on the outer surface of the mounting plate 122, and the telescopic end of the locking rod 133 is located in the mounting plate 122, pressing the carrier plate 123 tightly, so as to lock the carrier plate 123 to a limit. When the upper closing cover 31 is closed, the locking rod 133 is tightened. When moving toward the rotary mechanism 12, the surface provided with the conductive sheet first abuts against one end of the sleeve rod 134, and the conductive sheet contacts the first contact and the second contact, so that the circuit of the locking rod 133 is connected. Then, the telescopic end of the locking rod 133 is retracted, releasing the locking limit on the carrier plate 123, and then pushing the sleeve rod 134 to continue moving toward the rotary mechanism 12 until the pre-butting ring 3223 contacts the fan blade, until one end of the sleeve rod 134 is pressed tightly against the upper surface of the mounting plate 122, and at the same time, the upper sealing cover 311 abuts against the upper mounting plate 122. The surface of the upper sealing cover 311 facing the mounting plate 122 is provided with a groove for accommodating the sleeve rod 134, and the conductive sheet is correspondingly arranged in the groove; At this time, the sleeve rod 134 is in the second position, and the magnetic poles of the relative surfaces of the first magnet 131 and the second magnet 132 are the same, generating a repulsive force to push the fan blades to close to the pre-pressing ring 3223, forming a non-contact flexible buffer interface with the carrying plate 123. At this time, the elastic thrust of the disc spring 32223 and the repulsive force between the first magnet 131 and the second magnet 132 are relatively balanced, that is, the carrying plate 123 is at the relative midpoint position in the mounting plate 122. Subsequently, vibration transmission dust removal is carried out. In this process, the first magnet 131 and the second magnet 132 can filter vibration without affecting the vibration of the fan blades, play a flexible buffering role, ensure the vibration of the fan blades, avoid damage to the fan blades caused by hard connection, further reduce the vibration transmission to the mounting plate 122, and transmit the vibration to the rotary plate 121, affecting the work of other stations. The surface of the magnet is covered with an insulating coating to avoid electrostatic adsorption. When cleaning is completed, the upper closing cover 311 rises. At this time, the sleeve rod 134 is subjected to the elastic force of the reset spring 136 and moves back from the second position to the first position. After the pre-retaining ring 3223 leaves the fan blade, the carrier plate 123 is repelled by the repulsive force of the first magnet 131 and the second magnet 132 and rises and resets until the upper closing cover 311 leaves the sleeve rod 134. The telescopic end of the locking rod 133 extends to lock the carrier plate 123. The purpose is to prevent the lifting of the carrier plate 123 from affecting the cutting accuracy during the front cutting, and to prevent the lifting of the carrier plate 123 from affecting the gripping position when clamping the fan blade during the rear detection. The locking rod 133 can be an electric telescopic rod or a hydraulic telescopic rod, or it can be a telescopic rod. The telescopic rod is a mounting rod and an extension rod. The mounting rod has a built-in spring to extend the extension rod. A slot is provided on the surface of the supporting plate 123 corresponding to the telescopic rod. A magnet is provided in the slot. An electromagnet is provided on the end face of the extension rod corresponding to the slot. The first contact and the second contact are connected in series in the electromagnet circuit. When the first contact and the second contact are not connected, there is no magnetic force. When the upper closing cover 311 contacts the sleeve rod 134, the first contact is connected to the second contact, so that the electromagnet is energized, which is the same as the magnetic pole of the magnet, generating a repulsive force, so that the extension rod with the electromagnet is retracted into the mounting rod.

[0029] In this embodiment, the butterfly spring, the first magnet 131 , the second magnet 132 and the return spring 136 are selected specifically, and their acting force is sufficient to support the above process.

The dust removal assembly 30 is arranged on the surface of the machine table 5, and is arranged on one side of the rotating mechanism 12 in sequence along the rotation direction of the rotating mechanism 12 with the cutting assembly 20. A fan blade balance detection module is also provided on the surface of the machine table 5.
