Description

Technical Field

[0001] This application relates to the field of fan assembly technology, and in particular to a fan body assembly system. Background Technology

[0002] Household appliances such as computers and refrigerators have a large number of electronic components installed inside to achieve their various functions. These electronic components generate a lot of heat when they are working. In order to avoid the high operating temperature from affecting the performance and lifespan of the electronic components, heat dissipation and cooling units are usually added to dissipate heat from the electrical components. Common methods include liquid cooling and air cooling.

[0003] Air cooling is relatively inexpensive and therefore more widely used. Existing technology discloses a cooling fan, which includes a fan frame, fan blades, and a drive body. The drive body mainly includes a magnetic box and a magnetic strip with a certain degree of plasticity. The magnetic strip is strip-shaped after production. Because it is plastic, the operator will bend the magnetic strip into a ring and insert it into the magnetic box to form a magnetic frame. At this time, the magnetic box and the magnetic strip ring are roughly coaxial. Then, the magnetic frame is magnetized. After magnetization, the magnetic frame is inserted into the receiving cavity of the fan blade to form the fan body. Finally, the fan body is installed on the fan frame to obtain the cooling fan.

[0004] Regarding the aforementioned technologies, relying on operators to manually bend the magnetic strip into a ring shape before inserting it into the magnetic box, due to the small fit tolerance between the magnetic box and the magnetic strip ring, requires the use of a pressing device for insertion. However, the dimensions of the bent magnetic strip ring are greatly affected by factors such as the operator's experience, and may require repeated adjustments, thus affecting the assembly efficiency of the magnetic frame. Furthermore, if the outer diameter of the magnetic strip ring and the inner diameter of the magnetic box do not match, it may cause damage to the components during the pressing operation, or forcibly pressing it in may affect the quality of the magnetic frame. Summary of the Invention

[0005] To reduce the impact of operator experience on the efficiency of magnetic frame assembly and to ensure the quality of magnetic frame assembly, this application provides a fan body assembly system.

[0006] The fan body assembly system provided in this application adopts the following technical solution: A fan body assembly system, comprising: Installation platform; A molding and pressing block is connected to the mounting platform, and the molding and pressing block has a magnetic box cavity and a magnetic ring cavity arranged coaxially. The magnetic box cavity is located above the magnetic ring cavity, and the inner diameter of the magnetic box cavity is larger than the inner diameter of the magnetic ring cavity. The cutting blade is provided with a feeding channel on the plastic pressing block. The feeding channel is tangent to the magnetic ring cavity, and the cutting blade is located near the magnetic ring cavity in the feeding channel and slides in the vertical direction. A feeding unit for feeding magnetic strips into the feeding channel, the feeding unit being connected to the mounting platform and the molding and pressing block; A pressing unit for pressing the magnetic strip ring into the magnetic box, the pressing unit being connected to the mounting platform; An upper magnetic unit is disposed on one side of the plastic molding block and is connected to the mounting platform; The main assembly unit is used to press the magnetic frame into the fan blade, and the main assembly unit is connected to the mounting platform.

[0007] By adopting the above technical solution, the feeding unit feeds magnetic strips into the infeed channel from one end. After entering the magnetic ring cavity, the magnetic strips are bent into a magnetic strip ring due to the shape of the magnetic ring cavity. At the same time, the magnetic box is placed into the magnetic box cavity, and then the magnetic strip is cut by the cutting knife. Then, the pressing unit applies force to the magnetic strip ring and the magnetic box, so that the magnetic strip ring is pressed into the magnetic box to form a magnetic frame. Then, the magnetic frame is moved to the upper magnetic unit for magnetization. After the magnetic frame is magnetized, it is moved to the main assembly unit again, and the magnetized magnetic frame is pressed into the receiving cavity of the fan blade to obtain the fan body. The designed fan body assembly system can be used as a shaping and pressing unit through the mounting table. The installation base for the block, feeding unit, pressing unit, magnetizing unit, and main assembly unit is as follows: the molding and pressing block, together with the cutting knife and feeding unit, can bend the magnetic strip into a magnetic strip ring and cut it apart, reducing the dependence on manual labor in the production of magnetic strip rings. The shape of the magnetic ring cavity limits the size of the magnetic strip ring, reducing the impact of operator experience on the assembly efficiency of the magnetic frame and ensuring the quality and efficiency of the magnetic frame assembly. The pressing unit can press the magnetic strip ring into the magnetic box to form a magnetic frame. The magnetizing unit can complete the magnetization operation of the magnetic frame.

[0012] In one specific implementation, a storage cylinder for storing magnetic boxes is connected to the piston rod of the upper pressure cylinder. The storage cylinder is coaxially arranged with the magnetic box cavity, and a limiting mechanism is connected to the lower end of the storage cylinder. The limiting mechanism can abut against the top wall of the magnetic box in the magnetic box cavity.

[0013] By adopting the above technical solution, the designed storage cylinder can serve as a storage structure for multiple magnetic boxes. The limiting mechanism can restrict the discharge of magnetic boxes and can also restrict the position of magnetic boxes after abutting against the top wall of the magnetic box inside the magnetic box cavity, so as to press the magnetic strip ring into the magnetic box to obtain the magnetic frame.

[0014] In one specific implementation, the limiting mechanism includes: Multiple limiting plates are provided, and the limiting plates are rotatably connected to the bottom wall of the storage cylinder via torsion springs, and the rotation axis of the limiting plates is parallel to the central axis of the storage cylinder. A rotating ring is coaxially arranged and rotatably connected to the storage cylinder, and a plurality of protrusions are formed on the rotating ring. After the rotating ring rotates, the protrusions abut against the limiting plate, causing the free end of the limiting plate to move toward the central axis of the storage cylinder.

[0015] By adopting the above technical solution, the designed limiting mechanism can realize the single feeding of the magnetic box through the combination of the limiting plate and the rotating ring. After the rotating ring rotates, it can push the limiting plate towards the central axis of the storage cylinder, thereby serving as the upper limit of the magnetic box in the magnetic box cavity.

[0020] In one specific implementation, a feeding bar is connected to the mounting platform, and a material receiving groove with one side open is formed on the feeding bar. The positioning cavity on the positioning block is set downward toward the material receiving groove, and the piston rod of the pressing cylinder extends into the material receiving groove to push the magnetic frame in the material receiving groove toward the fan blade.

[0021] By adopting the above technical solution, the designed feeding bar can store multiple magnetic frames at one time, and together with the downward-facing positioning block and pressing cylinder, it can improve the assembly efficiency of the fan body.

A rotating motor is connected to the piston rod of the lifting cylinder. A mounting bracket having multiple forked portions, the mounting bracket being connected to the output shaft of the rotating motor, and a gripper being connected to one end of each forked portion of the mounting bracket; The rotation of the output shaft of the rotary motor causes the gripper to reciprocate between the inserting rod and the pressing position.

[0023] By adopting the above technical solution, the designed transfer unit can drive the rotating motor to lift and lower through the lifting cylinder, and drive the mounting frame to rotate through the rotating motor. The multiple forks on the mounting frame can serve as the mounting base for multiple grippers. The grippers can hold the magnetic frame and cooperate to realize the movement of the magnetic frame between the plastic pressing block and the stringing rod, and between the stringing rod and the feeding bar.

[0024] In one specific implementation, the mounting platform includes three mounting modules, with adjacent mounting modules being detachably and fixedly connected, and each mounting module is equipped with self-locking casters.

[0025] By adopting the above technical solution, the designed mounting platform, which includes three mounting modules, can reduce the processing difficulty of the mounting platform and change the relative positions of the structures mounted on each mounting module.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The designed fan assembly system uses a mounting platform as the base for the molding and pressing block, feeding unit, pressing unit, magnetizing unit, and main assembly unit. The molding and pressing block, together with the cutting knife and feeding unit, can bend the magnetic strip into a magnetic ring and cut it apart, reducing the reliance on manual labor in magnetic ring production. The shape of the magnetic ring cavity limits the size of the magnetic ring, reducing the impact of operator experience on the assembly efficiency of the magnetic frame and ensuring the quality and efficiency of the magnetic frame assembly. The pressing unit can press the magnetic ring into the magnetic box to form the magnetic frame. The magnetizing unit can complete the magnetization operation of the magnetic frame. The main assembly unit can assemble the magnetic frame and fan blades to obtain the fan body.

[0027] The designed fan assembly system can achieve single feeding of the magnetic box by using a limiting plate in conjunction with a rotating ring. After the rotating ring rotates, it can push the limiting plate toward the central axis of the storage cylinder, thus serving as the upper limit of the magnetic box inside the magnetic box cavity.

[0028] The designed fan assembly system uses a lifting cylinder to drive a rotating motor to lift and lower, which in turn drives the mounting frame to rotate. Multiple forks on the mounting frame serve as mounting bases for multiple grippers. These grippers hold the magnetic frame and work together to move the magnetic frame between the molding pressing block and the stringing rod, and between the stringing rod and the feeding bar.

Specifically, the feeding unit 4 includes a guide frame 41 and multiple drive wheels 42. A guide channel is formed inside the guide frame 41. The guide frame 41 is bolted to the installation module 11 and abuts against the molding and pressing block 2. One end of the guide channel in the guide frame 41 is connected to the feeding channel 23. The drive wheels 42 are rotatably connected to the guide frame 41. The rotation axes of the multiple drive wheels 42 are parallel to each other. The rotation axes of the drive wheels 42 are vertical. The drive wheels 42 can extend into the guide channel and roll to the side wall of the magnetic strip, so that the magnetic strip moves towards the feeding channel 23 in the guide channel.

[0044] Reference Figure 4 and Figure 5Furthermore, the fan assembly system also includes a pressing unit 5, which is connected to the mounting platform 1 and is used to press the magnetic strip ring into the magnetic box to form a magnetic frame. Specifically, the pressing unit 5 includes a lowering cylinder 51, a pushing ring 52, a central cylinder 53, a central column 54, and an upper pressing cylinder 55.

[0051] The implementation principle of a fan body assembly system according to an embodiment of this application is as follows: the feeding unit 4 feeds a magnetic strip into the feeding channel 23 from one end. After entering the magnetic ring cavity 22, the magnetic strip is bent into a magnetic strip ring due to the shape of the magnetic ring cavity 22. At the same time, the magnetic box is placed into the magnetic box cavity 21. Then, the magnetic strip is cut by the cutting knife 3. Then, the pressing unit 5 applies force to the magnetic strip ring and the magnetic box, so that the magnetic strip ring is pressed into the magnetic box to form a magnetic frame. Then, the magnetic frame is moved to the upper magnetizing unit 6 for magnetization. After the magnetic frame is magnetized, it is moved to the main body assembly unit 7 again, and the magnetized magnetic frame is pressed into the receiving cavity of the fan blade to obtain the fan body. The mounting table 1 can be used for shaping and pressing. The installation base of block 2, feeding unit 4, pressing unit 5, magnetizing unit 6, and main assembly unit 7 is formed by the molding and pressing block 2 in conjunction with the cutting knife 3 and feeding unit 4. The magnetic strip can be bent into a magnetic strip ring and cut and separated, which reduces the dependence on manual labor in the production of magnetic strip rings. The shape of the magnetic ring cavity 22 limits the size of the magnetic strip ring, reduces the impact of operator experience on the assembly efficiency of the magnetic frame, and ensures the quality and efficiency of the magnetic frame assembly. The pressing unit 5 can press the magnetic strip ring into the magnetic box to form a magnetic frame. The magnetizing unit 6 can complete the magnetization operation of the magnetic frame. The main assembly unit 7 can assemble the magnetic frame and the fan blades to obtain the fan body.
