Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular to a cooling fan feeding device. Background Technology

[0002] Cooling fans are important components to ensure the normal operation of equipment. For example, cooling fans installed on motors can accelerate the dissipation of heat generated during motor operation, so as to avoid the motor from failing to operate normally due to overheating.

[0003] Currently, after the cooling fans are produced, they are usually placed directly on the loading platform so that when the cooling fans are installed on the equipment, the cooling fans can be loaded directly from the loading platform.

[0004] However, in actual working environments, there are usually many cooling fans on the loading platform, and they come in various models. This makes it easy for the wrong model of cooling fan to be taken from the loading platform when installing the cooling fan on the equipment. As a result, it is necessary to put the wrong model of cooling fan back on the loading platform and take the correct model of cooling fan from the loading platform again. This operation is more troublesome and reduces the efficiency of the cooling fan loading operation. Utility Model Content

[0005] In view of this, the cooling fan feeding device provided in this application can reduce the efficiency of cooling fan feeding operations.

[0006] This application provides a cooling fan feeding device for holding multiple models of cooling fans. The cooling fan feeding device includes a workbench, a material tray, and multiple material columns. The material tray is disposed on one side of the workbench and is rotatably connected to the workbench about a target axis passing through the material tray. The target axis is parallel to the thickness direction of the material tray. The length direction of the material columns is parallel to the thickness direction of the material tray. The material columns are disposed on the side of the material tray away from the workbench, and the end of the material column near the material tray is connected to the material tray. The multiple material columns are circumferentially distributed around the target axis, and each material column is used to fit a corresponding model of cooling fan. At least two of the multiple material columns correspond to different models.

[0007] In one possible implementation, a first driving component is provided on the worktable for driving the material tray to rotate relative to the worktable. An electronic tag is connected to the end of the material column near the material tray, and a reader is connected to the worktable. The electronic tag stores model information corresponding to the connected material column. During the process of the first driving component driving the material tray to rotate unidirectionally relative to the worktable, each electronic tag is sequentially positioned opposite the reader, so that the reader sequentially reads the model information stored in the electronic tag opposite the reader.

[0008] In one possible implementation, a feeding area is provided on the side of the workbench near the material column, and the cooling fan feeding device further includes a controller; the distance between the feeding area and the target axis is equal to the distance between the material column and the target axis; the reader and the first drive are both electrically connected to the controller, and after the model information read by the reader is the same as the target model information, the controller controls the first drive to drive the material tray to rotate relative to the workbench, so that the target material column connected to the electronic tag storing the target model information is rotated to a position opposite to the feeding area, wherein the target model information is the model information of the cooling fan to be fed.

[0009] In one possible implementation, a base is slidably connected to the material column along its length, and a lifting column is provided in the loading area of ​​the worktable; at least a portion of the base is located outside the material column, and a cooling fan sleeved on the material column is located on the side of the base connected to the material column away from the material tray; the lifting column is slidably connected to the worktable along a direction parallel to the thickness of the material tray, the length direction of the lifting column is parallel to the thickness direction of the material tray, and the lifting column is connected to a second driving member for driving the lifting column to slide relative to the worktable; the lifting column is rotated when the target material column is rotated. After being moved to a position opposite to the loading area, the device moves relative to the worktable in the direction from the worktable to the material tray under the drive of the second drive member, so as to push the base connected to the target material column to slide relative to the target material column away from the material tray, until the cooling fan to be loaded is moved to the end of the target material column away from the material tray. The cooling fan to be loaded is the cooling fan with the farthest distance from the material tray among the cooling fans attached to the target material column after the target material column is rotated to a position opposite to the loading area and before the cooling fan is removed from the target material column.

[0010] In one possible implementation, after the cooling fan to be loaded is moved to the end of the target material column away from the material tray and the cooling fan to be loaded is removed from the target material column, the lifting column moves relative to the worktable in the direction from the worktable to the material tray under the drive of the second driving member, so as to push the base connected to the target material column to slide relative to the target material column away from the material tray until the cooling fan currently sleeved on the target material column that is furthest from the material tray is moved to the end of the target material column away from the material tray.

[0011] In one possible implementation, the material tray has through-holes extending along the thickness direction of the material tray near each of the material columns. A base plate is connected to the end of each material column near the material tray. The material column is tubular, and the base support portion is located within the inner cavity of the material column connected to the base support. The thickness direction of the base plate is parallel to the length direction of the material column. The base plate covers the through-hole closest to the material column connected to the base plate. A through-hole is extending along the thickness direction of the base plate, communicating with the through-hole covered by the base plate, and communicating with the inner cavity of the material column connected to the base plate. During the process of the lifting column pushing the base support to slide away from the material tray relative to the target material column, the end of the lifting column away from the worktable passes through the through-hole and the through-hole communicating with the inner cavity of the target material column, pushing the portion of the base support located inside the target material column, causing the portion of the base support located outside the target material column to slide away from the material tray.

[0012] In one possible implementation, the base includes a sleeve, an inner block, and at least one sliding post; the sleeve is fitted over the material column, and the cooling fan closest to the material tray among the cooling fans fitted over the material column abuts against the end face of the sleeve fitted over the material column away from the material tray; the inner block is located inside the material column and inside the sleeve; the length direction of the sliding post is perpendicular to the length direction of the material column, and the material column is provided with a sliding groove that slides with each sliding post, the length direction of the groove being parallel to the length direction of the material column, the groove extending from the inner wall of the material column to the outer wall of the material column, the sliding post passing through the sliding groove and through the wall of the sleeve, the first end of the sliding post being inside the cavity of the material column and connected to the inner block, and the second end of the sliding post being located outside the sleeve.

[0013] In one possible implementation, both ends of the chute along its length are closed.

[0014] In one possible implementation, the at least one sliding post includes two sliding posts, and the axes of the two sliding posts included in the same base coincide.

[0015] In one possible implementation, the material column is in the shape of a cylindrical tube, and the diameters of the material columns of different models are different, while the diameters of the material columns of the same model are the same.

[0016] As described in the above technical solution, the cooling fan feeding device includes a worktable, a material tray, and multiple material columns. The material tray is rotatably connected to one side of the worktable, and the material columns are located on the side of the material tray away from the worktable, with their ends connected to the material tray. During the use of the cooling fan feeding device, different models of cooling fans can typically be fitted onto their corresponding material columns. When installing a target model of cooling fan on the equipment requiring the fan, the material tray can be rotated relative to the worktable to rotate the material column fitted with the target model of cooling fan to a preset feeding position. Finally, a robotic arm or other tool can be used to remove the cooling fan from the material column furthest from the material tray, thus completing the feeding operation for the target model of cooling fan. Therefore, since different models of cooling fans are fitted onto different material columns, the possibility of removing the wrong model of cooling fan from the device is reduced, thereby reducing rework and improving the efficiency of the cooling fan feeding operation.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0031] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] As mentioned earlier, cooling fans are crucial components for ensuring the normal operation of equipment. For example, cooling fans installed on motors can accelerate the dissipation of heat generated during motor operation, minimizing the risk of the motor malfunctioning due to overheating. Currently, after the cooling fans are manufactured, they are typically placed directly on the loading platform so that they can be easily removed from the platform when installing them on the equipment. However, in actual operating environments, the loading platform usually contains a large number of cooling fans of various models. This makes it easy for the wrong model of cooling fan to be removed from the platform during installation, requiring the incorrect model to be returned to the platform and the correct model to be removed again. This process is cumbersome and reduces the efficiency of cooling fan loading.

[0033] In this embodiment, the cooling fan feeding device includes a worktable, a material tray, and multiple material columns. The material tray is rotatably connected to one side of the worktable, and the material columns are located on the side of the material tray away from the worktable, with the ends of the material columns connected to the material tray. During the use of the cooling fan feeding device, different models of cooling fans can typically be fitted onto their corresponding material columns. When installing a target model of cooling fan on the equipment where the fan needs to be installed, the material tray can be controlled to rotate relative to the worktable, causing the material column fitted with the target model of cooling fan to rotate to a preset feeding position. Finally, a robotic arm or other tool can be used to remove the cooling fan on the material column that is furthest from the material tray, thus completing the feeding operation of the target model of cooling fan. Therefore, different models of cooling fans are fitted onto different material columns, reducing the possibility of removing the wrong model of cooling fan from the device during feeding operations, thereby reducing rework and improving the efficiency of cooling fan feeding operations.

[0034] The vortex cooling fan feeding device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0035] The vortex cooling fan feeding device provided in this application embodiment is used to hold multiple models of cooling fans. Figure 1 This is a schematic diagram of a cooling fan provided in an embodiment of this application. See also... Figure 1 The cooling fan 1 includes an inner tube 11, a ring plate 12, multiple fan blades 13, and a protruding strip 14. The ring plate 12 is sleeved on one end of the inner tube 11. The multiple fan blades 13 are distributed in a circle around the inner tube 11 and are fixedly connected to the ring plate 12. The protruding strip 14 is long and parallel to the length direction of the inner tube 11. The protruding strip 14 is located inside the cavity of the inner tube 11 and is fixedly connected to the inner wall of the inner tube 11.

[0036] Figure 2 This is a schematic diagram of the structure of a cooling fan feeding device provided in an embodiment of this application. Figure 2 Part of the sliding column 422 was blown out of the sleeve 423 (the sliding column 422 and the sleeve 423 will be described later). Figure 3 This is an exploded view of a material column and its surrounding structure provided in an embodiment of this application. For example... Figure 2 and Figure 3As shown, the cooling fan feeding device includes a workbench 2, a material tray 3, and multiple material columns 4. The material tray 3 is located on one side of the workbench 2, and the material tray 3 is rotatably connected to the workbench 2 around a target axis passing through the material tray 3. The target axis is parallel to the thickness direction of the material tray 3, for example, the target axis is the axis of the disc-shaped material tray 3. The length direction of the material column 4 is parallel to the thickness direction of the material tray 3. The material column 4 is located on the side of the material tray 3 away from the workbench 2. The end of the material column 4 near the material tray 3 is connected to the material tray 3. The multiple material columns 4 are distributed in a circle around the target axis. Each material column 4 is used to fit a corresponding model of cooling fan 1. At least two of the multiple material columns 4 correspond to different models. The fitting of the material column 4 to the cooling fan 1 specifically means that the inner tube 11 of the cooling fan 1 is fitted onto the outside of the material column 4.

[0037] In this embodiment, the cooling fan feeding device includes a workbench 2, a material tray 3, and multiple material columns 4. The material tray 3 is rotatably connected to one side of the workbench 2, and the material columns 4 are located on the side of the material tray 3 away from the workbench 2. The end of the material column 4 near the material tray 3 is connected to the material tray 3. In the process of using the cooling fan feeding device, different models of cooling fans 1 can usually be fitted onto the material columns 4 corresponding to their models. When installing the target model of cooling fan 1 on the equipment (e.g., a motor) that needs to install the cooling fan 1, the material tray 3 can be controlled to rotate relative to the workbench 2 so that the material column 4 fitted with the target model of cooling fan 1 rotates to the preset feeding position. Finally, the cooling fan 1 that is furthest away from the material tray 3 fitted onto the material column 4 can be removed by a robotic arm or other tools to realize the feeding operation of the target model of cooling fan 1. Therefore, different models of cooling fans 1 are fitted onto different material columns 4. When using the cooling fan feeding device for feeding operations, the possibility of taking the wrong model of cooling fan 1 from the cooling fan feeding device is reduced, thereby reducing the number of rework operations and improving the feeding efficiency of cooling fan 1.

[0038] Figure 4 This is a top view of a cooling fan feeding device provided in an embodiment of this application. (Refer to...) Figure 3 and Figure 4The workbench 2 is equipped with a first driving component 21 for driving the material tray 3 to rotate relative to the workbench 2. The first driving component 21 can be, for example, a cam motor, which can control the material tray 3 to rotate at a fixed rotation angle, so as to ensure the stability of the rotation of the material tray 3 as much as possible, while also taking into account economy. An electronic tag 41 is connected to the end of the material column 4 near the material tray 3. A reader 22 is connected to the workbench 2. The electronic tag 41 and the reader 22 can be, for example, electronic tags 41 and readers 22 based on radio frequency identification (RFID) technology. The electronic tag 41 stores the model information corresponding to the connected material column 4. During the process of the first driving component 21 driving the material tray 3 to rotate unidirectionally relative to the workbench 2 (e.g., counterclockwise or clockwise rotation), each electronic tag 41 is sequentially opposite to the reader 22, so that the reader 22 sequentially reads the model information stored in the electronic tag 41 opposite to the reader 22.

[0039] In one specific implementation, when installing a target model of cooling fan 1 on a device that requires the installation of a cooling fan 1, the model information of the target model (hereinafter referred to as the target model information) can be obtained first. Then, the material tray 3 is controlled to start rotating unidirectionally relative to the workbench 2 by the first driving component 21. During the unidirectional rotation of the material tray 3, each electronic tag 41 is aligned with the reader 22 in sequence, so that the reader 22 reads the model information stored in the corresponding electronic tag 41 in sequence. Then, the model corresponding to each material column 4 can be determined by the reader 22.

[0040] Therefore, the reader 22 and the electronic tag 41 can automatically determine the model corresponding to each material column 4, that is, determine the model of the cooling fan 1 attached to each material column 4, further reducing the possibility of taking the wrong model of cooling fan 1 from the cooling fan feeding device and improving the feeding efficiency of the cooling fan 1.

[0041] In one possible implementation, such as Figure 2 , Figure 3 and Figure 4As shown, a feeding area 23 is provided on the side of the workbench 2 near the material column 4. The cooling fan feeding device also includes a controller (not shown in the attached figure). The distance between the feeding area 23 and the target axis is equal to the distance between the material column 4 and the target axis. The distance between the feeding area 23 and the target axis is the distance between the center of the feeding area 23 and the target axis, and the distance between the material column 4 and the target axis is the distance between the axis of the material column 4 and the target axis. The reader 22 and the first drive unit 21 are both electrically connected to the controller. After the model information read by the reader 22 is the same as the target model information, the controller controls the first drive unit 21 to drive the material tray 3 to rotate relative to the workbench 2, so that the target material column connected to the electronic tag 41 storing the target model information is rotated to a position opposite to the feeding area 23. The target model information is the model information of the cooling fan to be fed.

[0042] In one specific embodiment, during the unidirectional rotation of the material tray 3, the reader 22 can upload the model information stored in each electronic tag 41 to the processing unit connected to the controller. When the processing unit receives a model information uploaded by the reader 22, it can compare the model information with the target model information. If the model information is the same as the target model information, it sends an action signal to the controller, so that the controller controls the first drive unit 21 to stop driving the unidirectional rotation of the material tray 3 relative to the worktable 2, and the controller controls the first drive unit 21 to drive the material tray 3 to rotate relative to the worktable 2, so that the target material column connected to the electronic tag 41 storing the target model information is rotated to a position opposite to the loading area 23.

[0043] Therefore, by setting a controller, when the model information read by the reader 22 is the same as the target model information, the target material column can be directly rotated to a position opposite to the feeding area 23, so that the tool can take the target model cooling fan from the cooling fan feeding device.

[0044] In one possible implementation, refer to Figure 2 and Figure 3 A base support 42 is slidably connected to the material column 4 along its length direction. A lifting column 24 is provided in the loading area 23 on the worktable 2. At least a portion of the base support 42 is located outside the material column 4. The cooling fan 1 connected to the material column 4 is located on the side of the base support 42 connected to the material column 4 away from the material tray 3. The lifting column 24 is slidably connected to the worktable 2 along a direction parallel to the thickness of the material tray 3. The length direction of the lifting column 24 is parallel to the thickness direction of the material tray 3. A second driving component is connected to the lifting column 24 for driving the lifting column 24 to slide relative to the worktable 2. The second driving component can be, for example, a servo electric cylinder. The second driving component can be set on the worktable 2 (the second driving component is not shown in the figure). The embodiment of this application does not limit the setting position and specific type of the second driving component.

[0045] After the target material column is rotated to a position opposite to the loading area 23, the lifting column 24 moves relative to the worktable 2 in the direction from the worktable 2 to the material tray 3 under the drive of the second drive component, so as to push the bottom support 42 connected to the target material column to slide away from the material tray 3 relative to the target material column until the cooling fan to be loaded is moved to the end of the target material column away from the material tray 3, that is, the cooling fan to be loaded is moved to the end of the target material column away from the material tray 3 and is located inside the inner tube 11 of the cooling fan to be loaded. The cooling fan to be loaded is the cooling fan 1 with the farthest distance from the material tray 3 among the cooling fans 1 attached to the target material column after the target material column is rotated to a position opposite to the loading area 23 and before the cooling fan 1 is removed from the target material column.

[0046] Therefore, the lifting column 24 can push the cooling fan to be loaded to the end of the target material column away from the material tray 3, making it easier to remove the cooling fan from the target material column later.

[0047] In one possible implementation, refer to Figure 2 and Figure 3 After the cooling fan to be fed is moved to the end of the target material column away from the material tray 3, and after the cooling fan to be fed is removed from the target material column, the lifting column 24 moves relative to the worktable 2 in the direction from the worktable 2 to the material tray 3 under the drive of the second drive member, so as to push the bottom support 42 connected to the target material column to slide relative to the target material column away from the material tray 3, until the cooling fan 1 currently sleeved on the target material column that is furthest from the material tray 3 is moved to the end of the target material column away from the material tray 3, that is, the cooling fan 1 is moved to the end of the target material column away from the material tray 3 and is located inside the inner tube 11 of the cooling fan 1.

[0048] Therefore, after the cooling fan to be loaded is removed from the target material column, the cooling fan 1 currently attached to the target material column that is furthest from the material tray 3 can also be pushed by the lifting column 24 to the end of the target material column that is far away from the material tray 3, so that the tool can continue to remove the target model cooling fan 1 from the target material column.

[0049] In one possible implementation, refer to Figure 2 and Figure 3Each material tray 3 has a through-hole 31 extending through it along the thickness direction near each material column 4. The end of each material column 4 near the material tray 3 is connected to a base plate 43. This connection can be detachable, such as a bolted connection. The material column 4 is tubular, and part of the base support 42 is located inside the cavity of the material column 4 connected to the base support 42. The thickness direction of the base plate 43 is parallel to the length direction of the material column 4. The base plate 43 covers the through-hole 31 closest to the material column 4 connected to the base plate 43. A through hole 431 extending through it along the thickness direction is provided on the base plate 43. The through hole 431 on the base plate 43 communicates with the through-hole 31 covered by the base plate 43, and the through hole 431 on the base plate 43 communicates with the cavity of the material column 4 connected to the base plate 43.

[0050] As the lifting column 24 pushes the base support 42 to slide away from the material tray 3 relative to the target material column, the end of the lifting column 24 away from the worktable 2 passes through the through opening 31 and through hole 431 that are connected to the inner cavity of the target material column, pushing the part of the base support 42 located inside the target material column to drive the part of the base support 42 located outside the target material column to slide away from the material tray 3.

[0051] Therefore, the lifting column 24 can push the base support 42 inside the material column 4, making the structure near the material column 4 in the cooling fan feeding device neater and more aesthetically pleasing, thus improving the appearance of the cooling fan feeding device. Furthermore, since the part of the base support 42 that directly abuts against the lifting column 24 is located inside the target material column, the possibility of impurities being trapped between the base support 42 and the lifting column 24 causing the cooling fan 1 on the target material column to be lifted too high can be reduced. This can further reduce the possibility of the cooling fan 1 on the cooling fan feeding device falling and breaking, thus improving the safety of the cooling fan feeding device.

[0052] In one possible implementation, refer to Figure 3 The base 42 includes a sleeve 423, an inner block 421, and at least one sliding post 422. The sleeve 423 is sleeved on the outside of the material column 4. The cooling fan 1 closest to the material tray 3 among the cooling fans 1 sleeved on the material column 4 abuts against the end face of the sleeve 423 that is furthest from the material tray 3. The inner block 421 is located inside the material column 4 and inside the sleeve 423. The length direction of the sliding post 422 is perpendicular to the length direction of the material column 4. The material column 4 is provided with a sliding groove 44 that slides and engages with each sliding post 422. The length direction of the sliding groove 44 is parallel to the length direction of the material column 4. The sliding groove 44 extends from the inner wall of the material column 4 to the outer wall of the material column 4. The sliding post 422 passes through the sliding groove 44 and through the wall of the sleeve 423. The first end of the sliding post 422 is inside the inner cavity of the material column 4 and connected to the inner block 421. This connection can be a detachable connection, such as a threaded connection. The second end of the sliding post 422 is located outside the sleeve 423.

[0053] In the embodiments of this application, during the process of the lifting column 24 pushing the base 42 to slide relative to the material column 4, the end of the lifting column 24 away from the worktable 2 pushes the inner block 421 to slide within the material column 4, so that the sliding column 422 slides within the sliding groove 44. At the same time, the sliding column 422 can drive the sleeve 423 to push the cooling fan 1 to move. Thus, the structure of the base 42 is simple, the cost is low, and it is easy to implement.

[0054] In one possible implementation, refer to Figure 3 Both ends of the chute 44 are closed along its length, meaning that the two ends of the chute 44 do not penetrate the material column 4 along its length. This reduces the possibility of the sliding column 422 coming off the material column 4, thereby reducing the possibility of the base support 42 coming off the material column 4 during the operation of the cooling fan feeding device and reducing the possibility of abnormal operation of the cooling fan feeding device.

[0055] In one possible implementation, refer to Figure 3 The number of sliding columns 422 included in the above-mentioned at least one sliding column 422 is two, that is, the number of sliding columns 422 included in each base support 42 is two. The axes of the two sliding columns 422 included in the same base support 42 coincide, that is, the two sliding columns 422 included in the same base support 42 are on the same straight line. Therefore, the possibility of the base support 42 being tilted and stuck relative to the material column 4 during the sliding process can be reduced, and the possibility of abnormal operation of the cooling fan feeding device can be reduced.

[0056] In one possible implementation, refer to Figure 3 The material column 4 is in the shape of a round tube. The diameter of the material column 4 is different for different models, and the diameter of the material column 4 is the same for the same model. Therefore, it is possible to avoid the material column 4 being fitted with a cooling fan 1 of a different model than the corresponding model. This reduces the possibility of taking the wrong model of cooling fan 1 from the cooling fan feeding device, reduces the number of rework operations, and improves the feeding efficiency of cooling fan 1.

[0057] Optionally, refer to Figure 3 A keyway 45 is provided on the outer wall of the material column 4. The length direction of the keyway 45 is parallel to the length direction of the material column 4. Both ends of the keyway 45 pass through the material column 4 along the length direction of the material column 4. The protruding strip 14 of the heat dissipation fan 1, which is sleeved on the material column 4, is inserted into the keyway 45 on the material column 4. When the heat dissipation fan 1, which is sleeved on the material column 4, is pushed by the bottom support 42 and moves relative to the material column 4, the protruding strip 14 slides in the keyway 45.
