Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a fan blade feeding mechanism. Background Technology

[0002] Currently, cooling fans are key components in electronic devices used for forced convection cooling, and are widely used in computers, communication equipment, and home appliances. Their structure typically includes components such as fan blades, a frame, bearings, and a drive motor, requiring efficient and precise assembly of each part during the manufacturing process.

[0003] The fan blades in a cooling fan are the core airflow driving components, usually made of plastic or metal. Their shape, number, and angle directly determine the heat dissipation efficiency, air pressure, and noise. Related technologies involve placing several fan blades in a vibratory feeder during the feeding process. As the vibratory feeder vibrates, the blades are transported to the processing equipment. During this transport process, the fan blades are easily damaged, and their forward / backward rotation direction needs to be distinguished.

[0004] In practical use, damaged fan blades can cause dynamic imbalance, leading to vibration, noise, and motor wear, and even posing a safety hazard of blade breakage and splashing. On the other hand, fan blades installed backwards can cause airflow to become turbulent or reversed, resulting in heat dissipation failure.

[0005] Therefore, there is an urgent need for a method that can reduce the damage to fan blades during transportation and the misalignment of fan blades, in order to meet the automated production requirements of high-precision cooling fans. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a fan blade feeding mechanism, which solves the technical problems of fan blades being easily damaged during the conveying process and the fan blade direction being disordered.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A fan blade feeding mechanism includes: a frame with a feeding area and a discharging area, a material tray on the frame, and multiple positioning slots on the surface of the material tray for placing fan blades; the material tray loaded with fan blades is placed in the discharging area, and an empty material tray is unloaded in the discharging area; a conveying assembly mounted on the frame for conveying the empty material tray from the feeding area to the discharging area; a conveyor belt rotatably mounted on the frame for conveying the fan blades; and a feeding assembly mounted on the frame for conveying the fan blades from the positioning slots of the material tray onto the conveyor belt.

[0009] Furthermore, a conveyor belt is provided on the frame, and the conveyor belt corresponds to the loading area and the unloading area. Two sets of conveyor belts are arranged at intervals in the corresponding loading area and unloading area. The two sides of the material tray are supported on the two sets of conveyor belts. A transmission motor is provided on the frame, and the transmission motor is used to drive the conveyor belt to rotate on the frame.

[0010] Furthermore, a lifting pallet is provided on the frame, and the lifting pallet is slidably installed between the two sets of conveyor belts. A lifting servo module is provided on the frame, and the lifting pallet is raised and lowered on the frame through the lifting servo module.

[0011] Furthermore, the conveying assembly includes a conveying frame that slides between the loading area and the unloading area. A sliding motor and a screw are provided on the frame. The sliding motor is mounted on the frame. One end of the screw is connected to the sliding motor, and the other end passes through the conveying frame. The screw is threadedly connected to the conveying frame.

[0012] Furthermore, a vacuum nozzle is installed on the transport frame, and several vacuum nozzles are arranged on the transport frame. The vacuum nozzles are connected to an external vacuum generator.

[0013] Furthermore, the feeding assembly includes a feeding rack, which is slidably mounted on the frame. The feeding rack is provided with a feeding nozzle, which is connected to an external vacuum generator. The frame is provided with an X-axis linear module, a Y-axis linear module, and a Z-axis linear module. The X-axis linear module is mounted on the frame, the Y-axis linear module is slidably mounted on the X-axis linear module, the Z-axis linear module is slidably mounted on the Y-axis linear module, and the feeding rack is mounted at one end of the Z-axis linear module.

[0014] Furthermore, a vision camera is provided on the Z-axis linear module, and the vision camera is signal-connected to the X-axis linear module, Y-axis linear module and Z-axis linear module. An LED light is installed on the side of the Z-axis linear module closest to the vision camera.

[0015] In summary, this application includes at least one of the following beneficial technical effects of the fan blade feeding mechanism:

[0016] 1. Several fan blades are placed in the positioning slots of the material tray. The positioning slots limit the movement of the fan blades, which can reduce the collision between two adjacent fan blades. During processing, the material tray is placed in the loading area of ​​the frame. Then the loading component transports the fan blades in the positioning slots of the material tray to the conveyor belt. The fan blades are transported by the conveyor belt. After the fan blades in the material tray are used, the handling component transports the empty material tray to the unloading area. Since the fan blades are placed in individual positioning slots, the damage to the fan blades can be reduced. In addition, since the direction of the fan blades has been calibrated at the beginning, the direction of the fan blades will not be confused during the transportation process, thus improving the processing efficiency of the cooling fan.

[0017] 2. The ease of lifting the material tray on the frame is improved by the setting of the conveyor belt, the conveyor motor, the lifting pallet and the lifting servo module;

[0018] 3. The arrangement of the transport frame and vacuum nozzle, as well as the loading frame and loading nozzle, improves the ease of transporting the material tray and fan blades on the frame. Attached Figure Description

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses a fan blade feeding mechanism.

[0026] Reference Figure 1 A fan blade feeding mechanism includes a frame 1 with a feeding area 11 and a discharging area 12. A material tray 13 containing fan blades is placed on the frame 1 in the feeding area 11, and an empty material tray 13 is discharged through the discharging area 12. A conveyor belt 2 is provided on the frame 1 to transport the fan blades. A feeding assembly 3 and a conveying assembly 4 are provided on the frame 1. The feeding assembly 3 transports the fan blades in the material tray 13 onto the conveyor belt 2, and the conveying assembly 4 transports the empty material tray 13 in the feeding area 11 to the discharging area 12.

[0027] Reference Figure 2 A positioning groove 131 is formed on the material tray 13, and several positioning grooves 131 are formed at intervals on the material tray 13. Several fan blades are placed sequentially in the positioning grooves 131 of the material tray 13. The frame 1 is equipped with a conveyor belt 14 and a conveyor motor 141 in both the loading area 11 and the unloading area 12. The mechanisms of the loading area 11 and the unloading area 12 are the same, and the material tray 13 can be raised and lowered within the loading area 11 and the unloading area 12. The structure in the loading area 11 will be described below only.

[0028] Two sets of conveyor belts 14 are spaced apart in the corresponding loading area 11. The two sets of conveyor belts 14 are rotatably mounted on the frame 1. A conveyor motor 141 is mounted on the frame 1 and drives the conveyor belts 14 to rotate on the frame 1. The material tray 13 is generally rectangular, with its two sides in the width direction resting on the two sets of conveyor belts 14. In use, the conveyor motor 141 in the loading area 11 drives the conveyor belts 14 to rotate forward on the frame 1, conveying the material tray 13 towards the side closer to the frame 1. Conversely, the conveyor motor 141 in the unloading area 12 drives the conveyor belts 14 to rotate in reverse, conveying the empty material trays 13 away from the frame 1.

[0029] A lifting pallet 15 is installed on the frame 1, corresponding to the loading area 11 and the unloading area 12, and located between the two sets of conveyor belts 14. A lifting servo module 151 is installed on the frame 1, vertically mounted on the frame 1. One end of the lifting pallet 15 is slidably mounted on the lifting servo module 151, and the other end extends between the two sets of conveyor belts 14. A laser sensor 152 is installed on the side of the loading area 11 and the unloading area 12 closest to the frame 1, facing inwards towards the loading area 11 and the unloading area 12. When the tray 13 moves to the side of the laser sensor 152 under the action of the conveyor belt 14, the lifting pallet 15 rises through the lifting servo module 151, lifting the tray 13.

[0030] Reference Figure 3The feeding assembly 3 includes a feeding frame 31, which is slidably mounted on the frame 1. The feeding frame 31 is provided with a feeding nozzle 32, which is connected to an external vacuum generator. When the feeding nozzle 32 is pressed against the plane of the fan blade, the feeding nozzle 32 will lift the fan blade.

[0031] The frame 1 is equipped with an X-axis linear module 33, a Y-axis linear module 34, and a Z-axis linear module 35. The X-axis linear module 33 is mounted on the frame 1, the Y-axis linear module 34 is slidably mounted on the X-axis linear module 33, and the Z-axis linear module 35 is slidably mounted on the Y-axis linear module 34. A loading rack 31 is mounted on the side of the Z-axis linear module 35 closest to the frame 1. In use, the loading nozzle 32 on the loading rack 31 places the fan blades onto the conveyor belt 2 via the X-axis linear module 33, the Y-axis linear module 34, and the Z-axis linear module 35.

[0032] A vision camera 36 is mounted on the Z-axis linear module 35, facing towards the side closest to the material tray 13. The vision camera 36 is signal-connected to the X-axis linear module 33, Y-axis linear module 34, and Z-axis linear module 35. In use, the vision camera 36 positions the fan blades on the material tray 13. Then, the X-axis linear module 33, Y-axis linear module 34, and Z-axis linear module 35, using the positioning provided by the vision camera 36, ​​press the loading suction cup against the fan blade surface, moving the fan blades onto the conveyor belt 2. An LED light 37 is mounted on the side of the Z-axis linear module 35 closest to the vision camera 36. The LED light 37 is circular, providing supplementary lighting to the vision camera 36, ​​improving the accuracy of the vision camera's recognition of the fan blades.

[0033] After the fan blades on the material tray 13 have been used up, the empty material tray 13 in the loading area 11 needs to be moved to the unloading area 12. The handling assembly 4 includes a handling frame 41, which is slidably mounted on the frame 1. Vacuum nozzles 42 are provided on the handling frame 41, with four vacuum nozzles 42 spaced apart on the handling frame 41. The four vacuum nozzles 42 correspond to the four corners of the quadrilateral material tray 13. In use, the vacuum nozzles 42 are connected to an external vacuum generator. When the vacuum nozzles 42 are pressed against the material tray 13, the vacuum generator draws air from the vacuum nozzles 42.

[0034] A sliding motor 43 and a screw 44 are mounted on the frame 1. The screw 44 is rotatably mounted on the frame 1, and the output shaft of the sliding motor 43 is connected to the screw 44. In use, the sliding motor 43 drives the screw 44 to rotate forward or backward. A slider 45 is slidably mounted on the frame 1. One end of the screw 44 passes through the slider 45, and the screw 44 and the slider 45 are threadedly connected. By rotating the screw 44 forward or backward, the slider 45 is driven to slide back and forth on the frame 1.

[0035] A lifting cylinder 46 is installed on the slider 45. The lifting cylinder 46 is vertically mounted on the slider 45, and one end of the piston rod of the lifting cylinder 46 is connected to the transport frame 41. The vacuum nozzle 42 on the transport frame 41 is pressed against the material tray 13 by the lifting cylinder 46, and then the material tray 13 is lifted by the lifting cylinder 46. Then, the sliding motor 43 drives the screw 44 to rotate, and the transport frame 41 moves to the side closer to the unloading area 12. The vacuum nozzle 42 swings the empty material tray 13 onto the lifting tray of the unloading area 12. Then, the lifting tray 15 places the material tray 13 on the conveyor belt 2 through the lifting servo module 151. Finally, the conveyor motor 141 transports the material tray 13 to the side away from the frame 1 through the conveyor belt 14.

[0036] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
