Description

Technical Field

[0001] This invention relates to the field of bearing installation technology for fans, and more particularly to a convenient bearing installation device for household fans. Background Technology

[0002] Bearings are the core transmission components of household fan motors, and their installation accuracy and quality directly determine the fan's operational stability, noise level, and lifespan. In current household fan manufacturing processes, bearing installation and pre-testing stages generally suffer from numerous technical challenges, making it difficult to meet the demands of large-scale, high-precision production.

[0003] Currently, bearing installation largely relies on manual labor or semi-automated equipment. During manual installation, operators need to manually move the bearing, end cover, and fan motor, which is not only labor-intensive and inefficient, but also prone to misalignment of the bearing with the end cover and motor shaft due to manual positioning errors, causing problems such as installation jamming and component wear. In addition, the pre-inspection of bearings mainly targets surface defects and does not simulate the actual working scenario of "inner ring fixed and outer ring rotating," making it difficult to detect core functional defects such as jamming, non-rotation, and rotational jamming. When defective bearings are mixed into the assembly process, they can easily cause fan malfunctions, significantly reducing the product pass rate. At the same time, the separation efficiency between qualified and defective bearings after inspection is low, and mixed flow can easily occur, further affecting production quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of poor pre-installation testing of bearings in the prior art, and to propose a convenient bearing installation device for household fans.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a convenient bearing installation device for a household fan, comprising a mounting frame, a fan assembly, and a control system. The fan assembly includes a bearing, a fan motor, and an end cover. The mounting frame is provided with an installation mechanism, a conveying mechanism, and a detection mechanism. The detection mechanism includes a feeding platform and a support mounted on the mounting frame, and a turntable capable of rotation and lifting is provided between the feeding platform and the support. A pushing component is provided on the side of the feeding platform away from the turntable. A rotating shaft is rotatably connected to the mounting frame. The support is connected to the rotating shaft through a transmission component. Multiple inclined rods are evenly arranged along the circumference of the outer wall of the support. The upper part of the inclined rods is inclined, and a rubber pad is provided at the bottom. The installation mechanism includes an indexing plate. Two sets of installation components are symmetrically arranged on both sides of the indexing plate. Two sets of sliding components are provided on the mounting frame, and the two sets of sliding components correspond one-to-one with the two sets of installation components.

[0006] Preferably, the conveying mechanism includes a first conveyor belt, a second conveyor belt, and a third conveyor belt mounted on a mounting frame, with the indexing plate located above and corresponding to the third conveyor belt.

[0007] Preferably, a first motor is fixedly mounted on the mounting bracket, the output end of the first motor is fixedly connected to the rotating shaft, a second motor is fixedly mounted on the mounting bracket, and the indexing plate is fixedly connected to the output shaft of the second motor.

[0008] Preferably, the mounting assembly includes a mounting shaft and a heating rod mounted on the side wall of the indexing plate. The mounting shaft includes a base fixedly mounted on the side wall of the indexing plate, and a guide shaft is fixedly mounted at the end of the base. A gripper cylinder is provided on the indexing plate, and a temperature sensor and a temperature sensor corresponding to the position of the heating rod are fixedly mounted on the indexing plate.

[0009] Preferably, the outer wall of the guide shaft is provided with multiple through grooves evenly distributed around its circumference, and a slide plate is slidably connected in each through groove. The base is provided with an airbag for lifting the slide plate, and the side wall of the slide plate is evenly embedded with balls.

[0010] Preferably, the sliding assembly includes a slide table slidably connected to the mounting frame, an electric cylinder whose output end is fixedly connected to the slide table is fixedly mounted on the mounting frame, and a force sensor is provided inside the electric cylinder. A gripper cylinder is movably mounted on the slide table via a ball seat.

[0011] Preferably, the feeding platform has a discharge port, an inclined surface and a limiting plate inside. The inclined surface is used to guide the bearing to slide towards the discharge port, and the limiting plate is used to limit and separate the bearing inside the feeding platform.

[0012] Preferably, the pushing assembly includes a cylinder fixedly mounted on the mounting frame, and a push plate is fixedly mounted on the output end of the cylinder. The push plate corresponds to the position of the discharge port on the feeding platform. The lower half of the push plate is provided with a notch adapted to the shape of the turntable. The front part of the push plate is provided with a boss, and the outer diameter of the boss is smaller than the inner diameter of the bearing. The outer diameter of the inclined rod is smaller than the inner diameter of the boss at the front of the push plate.

[0013] Preferably, the transmission assembly includes a ratchet fixedly mounted on the inner wall of the support, two pawls that mesh with the ratchet are slidably connected to the side wall of the rotating shaft, and the two pawls are elastically connected by a second spring, which is used to ensure that the pawls remain in contact with the ratchet, and the top of the support is elastically connected to the rotating shaft by a first spring.

[0014] Preferably, an inclined plate corresponding to the position of the detection mechanism is fixedly installed on the mounting frame, and a material box for collecting defective products is placed below the inclined plate.

[0015] Compared with existing technologies, the advantages of this invention are: This invention increases the friction between the bearing's inner bore and the inclined rod by using a rubber pad, fixing the inner ring of the bearing while the outer ring rotates with the turntable. This simulates a real-world working scenario and can specifically detect core defects such as jamming, non-rotation, and rotational sluggishness, rather than surface flaws. Combined with the unidirectional transmission of the ratchet and pawl and the reset action of the spring, it achieves automatic separation of qualified and defective bearings. Qualified bearings slide onto the conveyor belt for continued transport, while defective bearings slide into the collection box via the inclined plate, preventing mixing and providing qualified parts for subsequent installation, thus improving the quality of the finished fan.

[0016] This invention achieves automated flow and assembly of bearings, fan motors, and end caps through the step-by-step rotation of the indexing plate combined with robotic arm transfer. An inflatable airbag drives the sliding plate to lift, securely clamping the bearings and preventing displacement during assembly. The universal ball joint allows for 360-degree fine-tuning, ensuring the bearings, end caps, and fan motor shafts are coaxial, compensating for component machining errors, and preventing damage caused by assembly deviations. A mechanical sensor monitors the assembly pressure in real time, stopping the operation when a set value is reached, accurately determining the installation position. This comprehensively improves installation accuracy and reliability while reducing manual operation and labor intensity. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Reference Figures 1 to 13 A convenient bearing installation device for a household fan includes a mounting frame, a fan assembly, and a control system (the control system includes a PLC, which is existing technology and will not be described in detail here). The fan assembly includes a bearing 1, a fan motor 2, and an end cover 3. The mounting frame is equipped with an installation mechanism, a conveying mechanism, and a detection mechanism 9. The conveying mechanism includes a first conveyor belt 4, a second conveyor belt 5, and a third conveyor belt 6 set on the mounting frame. The first conveyor belt 4 is used to convey the bearing 1, the second conveyor belt 5 is used to convey the fan motor 2, and the third conveyor belt 6 is used to convey the end cover 3 and the installed fan motor 2. A robotic arm (existing technology and will not be described in detail here) is provided next to the conveying mechanism for transferring the bearing 1, the fan motor 2, and the end cover 3.

[0021] The testing mechanism 9 includes a feeding platform 91, a turntable 92, and a support 94 mounted on a mounting frame. The turntable 92 is located between the feeding platform 91 and the support 94. The feeding platform 91 has a discharge port 910 and an inclined surface and a limiting plate 911 inside. The inclined surface guides the bearing 1 to slide towards the discharge port 910 by its own weight. The limiting plate 911 limits and separates the bearing 1 inside the feeding platform 91, ensuring that only one bearing 1 to be tested is fed to the discharge port 910 at a time, avoiding feeding jams caused by multiple parts stacking and improving the continuity of testing. A pushing assembly is provided on the side of the feeding platform 91 away from the turntable 92. The pushing assembly includes a fixed... A cylinder mounted on a mounting bracket has a push plate 99 fixedly mounted on its output end. The push plate 99 corresponds to the outlet 910 on the feed table 91. The bearing 1 slides down the inclined surface inside the feed table 91 to the outlet 910. The cylinder pushes the push plate 99 to extend, pushing the bearing 1 located in the outlet 910 out. The lower half of the push plate 99 has a notch that matches the shape of the turntable 92 to avoid interference between the push plate 99 and the turntable 92 during movement. The front part of the push plate 99 has a boss 913. The outer diameter of the boss 913 is smaller than the inner diameter of the bearing 1 to be inspected, so that it can be inserted into the inner hole of the bearing 1 during the pushing process and prevent it from falling out.

[0022] A first motor is fixedly mounted on the mounting bracket. A rotating shaft 95 is fixedly connected to the output end of the first motor. A support 94 is connected to the rotating shaft 95 via a transmission assembly. The transmission assembly includes a ratchet 916 fixedly mounted on the inner wall of the support 94. Two pawls 914, which mesh with the ratchet 916, are slidably connected to the side wall of the rotating shaft 95. The two pawls 914 are elastically connected by a second spring 915, which ensures that the pawls 914 remain in contact with the ratchet 916, achieving unidirectional transmission. Multiple diagonal rods 96 are evenly arranged circumferentially on the outer wall of the support 94. The upper part of each diagonal rod 96 is inclined, and a rubber pad 97 is provided at its bottom. The outer diameter of each diagonal rod 96 is smaller than that of a push rod. The inner diameter of the boss 913 at the front of the plate 99 is such that the boss 913 can pass through. The turntable 92 can rotate and lift through the drive mechanism. The drive mechanism can be a combination of a rotary drive unit (motor with slewing bearing or divider) and a lifting drive unit (screw, hydraulic cylinder or pneumatic mechanism) (this is prior art and will not be described in detail here). It is used to cooperate with the inclined bar 96 to clamp the bearing 1. The top of the support 94 is elastically connected to the rotating shaft 95 through a spring 98 to provide the reset torque. An inclined plate 912 is provided on the side of the feed table 91 away from the conveyor belt 4. A material box 93 for collecting defective products is placed below the inclined plate 912.

[0023] After the pusher plate 99 pushes the bearing 1 onto the inclined rod 96, the turntable 92 rotates and rises, clamping the bearing 1 between the turntable 92 and the inclined rod 96. Then the pusher plate 99 returns to its original position. Because the bottom of the inclined rod 96 is equipped with a rubber pad 97, the inner hole of the bearing 1 is difficult to rotate. Its outer ring contacts the turntable 92 and rotates with the turntable 92. The rubber pad 97 increases the friction between the inner hole of the bearing 1 and the inclined rod 96, making it impossible for the inner hole of the bearing 1 to rotate. Meanwhile, the turntable 92 contacts the outer ring of the bearing 1 and drives the outer ring to rotate, simulating the actual working scenario of the bearing 1 with "inner ring fixed and outer ring rotating". This detects core defects (rather than surface defects) that affect use, such as "jamming, no rotation, and rotational jamming". The detection is highly targeted. When the first motor drives the rotating shaft 95 to rotate in the set direction, the engagement of the pawl 914 and the ratchet 916 drives the support 94 and the inclined rod 96 on it. Synchronous unidirectional rotation. If the support 94 is subjected to a force opposite to the rotation direction of the rotating shaft 95, the pawl 914 and ratchet 916 will slip, and the support 94 will rotate in the opposite direction. When the reverse force disappears, the support 94 will return to the initial angle under the action of the spring 98, ensuring that the support 94 quickly returns to the initial position after the defective products are discharged, without affecting the inspection of the next bearing 1. The rotation direction of the turntable 92 is set to be opposite to the driving rotation direction of the rotating shaft 95. The support 94 rotates 90 degrees with the rotating shaft 95. The qualified bearing 1 slides down the inclined plane at the top of the inclined bar 96 onto the conveyor belt 4. If the bearing 1 has defects such as jamming or not rotating, it will drive the support 94 to rotate together when the turntable 92 rotates. Finally, the bearing 1 falls onto the inclined plate 912 and slides down the inclined plate 912 into the material box 93 for collection, avoiding the mixing of qualified and defective products.

[0024] The mounting mechanism includes an indexing plate 7, which is located above and corresponds to the conveyor belt 6. A second motor is fixedly mounted on the mounting frame, and the indexing plate 7 is fixedly connected to the output shaft of the second motor. The second motor drives the indexing plate 7 to achieve step-by-step rotation. Two sets of mounting components are symmetrically arranged on both sides of the indexing plate 7. The mounting components include a mounting shaft 71 and a heating rod 72 mounted on the side wall of the indexing plate 7. The heating rod 72 and the mounting shaft 71 are circumferentially distributed. The mounting shaft 71 includes a base 76 fixedly mounted on the side wall of the indexing plate 7. A guide shaft 77 is fixedly mounted at the end of the base 76. Multiple through slots are evenly distributed on the outer wall of the guide shaft 77. A sliding plate 79 is slidably connected in each through slot. Ball bearings are evenly embedded in the side wall of the sliding plate 79. An airbag 78 is provided inside the base 76. The airbag 78 is inflated. The expansion drive slide plate 79 is raised to clamp the bearing 1. Temperature sensor 1 73 and temperature sensor 2 74, corresponding to the position of heating rod 72, are fixedly installed on the indexing plate 7. Temperature sensor 1 73 is used to monitor the inner ring temperature of bearing 1, and temperature sensor 2 74 is used to monitor the outer ring temperature of bearing 1. The indexing plate 7 is provided with a gripper cylinder 1 75 for clamping the fan motor 2. Sliding components are respectively provided on both sides of the indexing plate 7. The sliding components include a slide table 8 slidably connected to the mounting frame. An electric cylinder is fixedly installed on the mounting frame. A force sensor is installed in the electric cylinder. The slide table 8 is fixedly connected to the transfusion end of the electric cylinder. Gripper cylinder 2 81 is movably installed on the slide table 8 through ball seat 82. Gripper cylinder 2 81 is used to clamp the end cover 3. The ball seat 82 is a universal ball seat, which can realize 360-degree angle fine adjustment.

[0025] The robotic arm places the qualified bearing 1 onto the guide shaft 77. The control system controls the airbag 78 to inflate with air at a certain pressure. The airbag 78 inflates, driving the slide plate 79 to lift and clamp the bearing 1. Simultaneously, the robotic arm on the other side places the end cap 3 into the gripper cylinder 81. The gripper cylinder 81 clamps the end cap 3. The indexing plate 7 rotates, causing the mounting shaft 71, carrying the bearing 1, to reach the slide table 8. The robotic arm then places the fan motor 2 onto the gripper cylinder 75. The gripper cylinder 75 immediately clamps the fan motor 2, and the electric cylinder pushes the slide table 8 forward, carrying the end cap 3. The end cap 3 contacts the bearing 1 on the guide shaft 77, and the bearing 1 slightly enters the bearing 1 hole of the end cap 3. Then, the end cap 3 pushes the bearing 1 forward toward the base 76. During this process, the ball seat 82 makes a fine adjustment of the angle to ensure that the bearing 1 and the end cap 3 are coaxial and to avoid damage to the parts due to errors. When the bearing 1 is in contact with the base 76, the end cap 3 presses the bearing 1 into the bearing 1 hole. After the force sensor in the electric cylinder detects that the pressure has reached the set value, the control system controls the electric cylinder to stop extending, the air bag 78 deflates, the slide table 8 resets, and the indexing plate 7 rotates to make the heating rod 7 2. Upon reaching slide 8, the robotic arm clamps bearing 1. Slide 8 advances, causing heating rod 72 to enter the inner hole of bearing 1. Induction heating heats the inner ring of bearing 1. Temperature sensor 1 73 and temperature sensor 2 74 monitor the temperature of the inner and outer rings of bearing 1 respectively and feed the signals back to the control system. The power of heating rod 72 is adjusted to prevent the inner ring from expanding too quickly due to temperature rise, which could cause the balls to seize or be damaged. After the inner ring temperature reaches the set value, slide 8 resets, and indexing plate 7 rotates, causing fan motor 2 to reach slide 8. Slide 8 advances, and the shaft of fan motor 2 is inserted into the shaft. The inner hole of bearing 1 is filled, and the ball seat 82 is finely adjusted again to ensure smooth insertion. After the force sensor in the electric cylinder detects that the pressure has reached the set value, it is determined that the installation is in place. The gripper cylinder 75 is released, and the installed fan motor 2 falls onto the conveyor belt 6 and enters the subsequent section. The previous operation cycle is repeated to install the bearing 1 of the fan motor 2. This is quick and convenient, reduces manual intervention, avoids large errors and low efficiency in manual installation, and reduces the corrosion of the fan motor 2 and bearing 1 by sweat and oil on the hands, which helps to improve the service life of the fan motor 2.

[0026] During operation, the indexing plate 7 rotates in steps. First, a robotic arm places the bearings 1 on conveyor belt 4 onto the guide shaft 77 of the mounting shaft 71. The airbag 78 is inflated with air at a certain pressure, causing the slide plate 79 to lift and clamp the bearings 1. Meanwhile, the robotic arm on the other side places the end cap 3 on conveyor belt 6 into the gripper cylinder 81 and clamps it. The indexing plate 7 rotates, and the mounting shaft 71, carrying the bearings 1, reaches the slide table 8. The robotic arm then places the fan motor 2 on conveyor belt 5 onto the gripper cylinder 75. The gripper cylinder 75 clamps the fan motor 2, and the slide 8, carrying the end cover 3, moves forward and contacts the bearing 1 on the guide shaft 77. The bearing 1 slightly enters the bearing 1 hole of the end cover 3, and the end cover 3 pushes the bearing 1 forward toward the base 76. During this process, the angle is finely adjusted by the ball seat 82 to ensure that the bearing 1 and the end cover 3 are coaxial. Finally, the bearing 1 fits into the base 76, and the end cover 3 presses the bearing 1 into the bearing 1 hole. The force sensor in the electric cylinder detects that the pressure has reached the set value and stops extending. The air bag 78 deflates, and the slide 8 resets.

[0027] The indexing plate 7 rotates, causing the heating rod 72 to reach the slide table 8. The robot arm clamps the bearing 1, and the slide table 8 moves forward, allowing the heating rod 72 to enter the inner hole of the bearing 1. The inner ring of the bearing 1 is heated by induction heating. Temperature sensor 1 73 and temperature sensor 2 74 monitor the inner and outer ring temperatures of the bearing 1 respectively and provide feedback, adjusting the power of the heating rod 72. After the inner ring reaches the set temperature, the slide table 8 resets, the indexing plate 7 rotates, and the fan motor 2 reaches the slide table 8. The slide table 8 moves forward, and the shaft of the fan motor 2 is inserted into the inner hole of the bearing 1. The ball seat 82 is finely adjusted to ensure smooth insertion and prevent damage to the bearing 1 and the fan motor 2. When the force sensor detects that the set pressure has been reached, it is determined that the installation is in place. The gripper cylinder 1 75 releases, and the installed fan motor 2 falls onto the conveyor belt 3 6 to enter the subsequent process section.

[0028] The bearing 1, which enters the discharge port 910, is pushed out by the push plate 99. After the push plate 99 pushes it into place, the turntable 92 rotates and rises to contact the bearing 1. The bearing 1 is clamped between the turntable 92 and the inclined rod 96. Then the push plate 99 returns to its original position. The inner hole of the bearing 1 is difficult to rotate due to the rubber pad 97, while the outer ring rotates in contact with the turntable 92. The rotating shaft 95 can drive the support 94 to rotate in one direction. When a force opposite to the rotation direction of the rotating shaft 95 occurs, the support 94 rotates in the opposite direction. When the force disappears, the support 94 can return to its original position under the action of the spring 98. The turntable 92 rotates in the opposite direction to the shaft 95. After a certain period of time, the turntable 92 resets, and the support 94 rotates 90 degrees with the shaft 95. The bearing 1 slides down the inclined surface at the top of the inclined bar 96 onto the conveyor belt 4 for conveying. When the bearing 1 is a defective product with defects such as jamming or not rotating, the support 94 rotates together under the action of the turntable 92. Finally, the bearing 1 falls onto the inclined plate 912 and slides into the material box 93 for collection. By removing the defective bearing 1, it is prevented that the problematic bearing 1 is installed in the fan motor 2, causing the fan to malfunction and improving the quality of the fan.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
