Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub classification, in particular to an automatic sorting device for wheel hubs. Background Art

[0002] A wheel hub is a cylindrical metal part that supports a tire inside the tire profile and is centered on an axle. It is also called a rim, steel rim, wheel, or tire bell. There are many different types of wheel hubs according to diameter, width, forming method, and material.

[0003] During the production process of wheel hubs, due to factors such as process and materials, defective products will inevitably be produced. In order to prevent defective wheel hubs from flowing into the market and causing safety accidents, workers need to sort out defective wheel hubs from the production line before leaving the factory. The efficiency of manual sorting is relatively low. Therefore, in view of the above problems, we propose a new type of automatic sorting device for wheel hubs. Content of the Utility Model

[0004] The utility model mainly provides an automatic sorting device for wheel hubs that is convenient for improving sorting efficiency and preventing defective wheel hubs from flowing into the market and causing safety accidents.

[0005] To achieve the above object, the utility model adopts the following technical scheme: an automatic sorting device for wheel hubs, including a frame. A second mounting frame is installed at a position near the rear side of the top of the frame. A second conveyor belt is installed between the inner walls of the second mounting frame near the bottom. A first rotating seat and a second rotating seat are symmetrically and fixedly connected to the inner walls of the front and rear sides of the second mounting frame near the middle. A rotating shaft is rotatably connected to the top of the first rotating seat. A first bevel gear is fixedly connected to the top end of the rotating shaft. A first baffle is fixedly connected to the outer surface of the rotating shaft.

[0006] Preferably, guiding frames are fixedly connected to the inner walls of the front and rear sides of the second mounting frame at positions to the left of the first rotating seat. A fourth mounting frame is fixedly installed at a position near the middle of the rear side of the top of the second mounting frame. A servo motor is installed on the rear surface of the fourth mounting frame. The guiding frames are mainly used to guide the wheel hubs on the second conveyor belt to prevent them from getting stuck after coming into contact with the first rotating seat and the second rotating seat. The second mounting frame is mainly used to install the servo motor. The servo motor adopts the model MCA17N23-RS0B0.

[0007] Preferably, the output end of the servo motor rotatably penetrates through the rear surface of the fourth mounting frame and extends to the front side. A second bevel gear is fixedly connected to the output end of the servo motor. The second bevel gear is meshed with the first bevel gear. The servo motor is controlled by a PLC controller. After starting, it can drive the second bevel gear to rotate. After the second bevel gear rotates, it can drive the first bevel gear to rotate.

[0008] Preferably, a first mounting bracket is installed at a position near the front side of the top of the rack. A first conveyor belt is installed between the inner surfaces of the first mounting bracket near the bottom. The first mounting bracket and the second mounting bracket have the same dimensions and are mainly used to install the first conveyor belt to convey the sorted defective hub wheels outwards.

[0009] Preferably, a communicating inclined opening is formed at a position near the middle on the outer surface of the relative sides of the first mounting bracket and the second mounting bracket. The communicating inclined opening corresponds to the position of the first baffle. The communicating inclined opening is mainly used to connect the first mounting bracket and the second mounting bracket, so that the hub wheels can be transferred from the second conveyor belt to the first conveyor belt conveniently.

[0010] Preferably, a third mounting bracket is installed at a position near the left side of the top of the first mounting bracket. A CCD camera is installed on the top of the third mounting bracket, and the camera of the CCD camera is located inside the third mounting bracket. A PLC controller is arranged on the front side of the rack. The PLC controller, the CCD camera and the servo motor are electrically connected by wires. The CCD camera adopts a camera of model WP-UT130, and the PLC controller adopts a CQM1 controller. When the automotive hub wheel to be sorted moves to the position below the CCD camera inside the third mounting bracket, the CCD camera detects the signal, takes a picture of the automotive hub wheel, and compares it with the qualified automotive hub wheel information stored in itself. When the automotive hub wheel is unqualified, the CCD camera transmits the signal to the PLC controller, and the PLC controller will control the servo motor to start.

[0011] Preferably, a rotating shaft is rotatably connected to the top of the second rotating seat. A second baffle is fixedly connected to the top of the rotating shaft. Bearings are embedded at the positions near the right edge of the tops of the second baffle and the first baffle. A connecting shaft is fixedly connected between the inner surfaces of the two bearings. A linkage plate is fixedly connected between the tops of the two connecting shafts. The second baffle is rotatably installed above the second rotating seat through the rotating shaft. The two ends of the linkage plate are respectively rotatably connected to the first baffle and the second baffle through the connecting shaft and the bearing, and the linkage plate is perpendicular to the first baffle and the second baffle. The four points of the rotating shaft, the rotating shaft and the two connecting shafts form a parallelogram. Therefore, when the rotating shaft drives the first baffle to rotate towards the first conveyor belt at the front side, the second baffle will be driven to rotate synchronously under the action of the linkage plate, and the distance between the first baffle and the second baffle will contract, so as to limit the defective hub wheels within a smaller range, and at the same time block the subsequent high-quality hub wheels from passing through. At the same time, under the action of the second conveyor belt continuously conveying the hub wheels to the right, the hub wheels will slide onto the first conveyor belt along the surface of the first baffle and be sorted out.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows

[0013] 1. In the present utility model, the hub is continuously conveyed to the right by the first conveyor belt. After the CCD camera detects a defective product, it sends an electrical signal to the PLC controller and starts the servo motor. The servo motor drives the first baffle to rotate forward through the cooperation of the second bevel gear, the first bevel gear, and the rotating shaft, and then the defective hub can be introduced onto the first conveyor belt and conveyed to other positions, realizing the sorting operation of defective products. It does not require manual participation, has a high degree of automation, can work continuously for a long time, and effectively improves the hub sorting efficiency.

[0014] 2. In the present utility model, the guiding frame is provided to guide the hub on the second conveyor belt, ensuring that the hub will not get stuck when passing through the positions of the first rotating seat and the second rotating seat, and ensuring the reliability of the device during use.

The outer surface of the rotating shaft 41 is fixedly connected to a first baffle 43.

[0023] As Figures 1 - 4 shown, guiding frames 2 are fixedly connected to the inner surfaces of the front and rear sides of the second mounting frame 13 at positions to the left of the first rotating seat 4. A fourth mounting frame 5 is fixedly installed at a position near the middle of the rear side of the top of the second mounting frame 13. A servo motor 51 is installed on the rear surface of the fourth mounting frame 5. The guiding frames 2 are mainly used for guiding the wheel hubs on the second conveyor belt 14 to prevent them from getting stuck after coming into contact with the first rotating seat 4 and the second rotating seat 6. The second mounting frame 13 is mainly used for installing the servo motor 51. The servo motor 51 has a model number of MCA17N23-RS0B0.

[0024] As Figure 1 , Figure 3 and Figure 4 shown, the output end of the servo motor 51 rotatably penetrates the rear surface of the fourth mounting frame 5 and extends to the front side. The output end of the servo motor 51 is fixedly connected to a second bevel gear 52. The second bevel gear 52 is meshed with the first bevel gear 42. The servo motor 51 is controlled by a PLC controller 32. After being started, it can drive the second bevel gear 52 to rotate. After the second bevel gear 52 rotates, it can drive the first bevel gear 42 to rotate.

[0025] As Figure 1 and Figure 2 shown, a first mounting frame 11 is installed at a position near the front side of the top of the frame 1. A first conveyor belt 12 is installed between the inner surfaces of the first mounting frame 11 near the bottom. The first mounting frame 11 and the second mounting frame 13 have the same dimensions and are mainly used for installing the first conveyor belt 12 to convey the sorted defective wheel hubs outwards.

[0026] As Figure 1 and Figure 2As shown in the figure, a communication inclined opening 21 is provided at a position near the middle on the outer surface of the relative sides of the first mounting bracket 11 and the second mounting bracket 13. The position of the communication inclined opening 21 corresponds to that of the first baffle 43. The communication inclined opening 21 is mainly used to connect the first mounting bracket 11 and the second mounting bracket 13, facilitating the transfer of the hub from the second conveyor belt 14 to the first conveyor belt 12.

[0027] As Figure 1 and Figure 2 shown in the figure, a third mounting bracket 3 is installed at a position near the left side of the top of the first mounting bracket 11. A CCD camera 31 is installed on the top of the third mounting bracket 3 and the camera of the CCD camera 31 is located inside the third mounting bracket 3. A PLC controller 32 is arranged on the front side of the frame 1. The PLC controller 32 and the CCD camera 31 are electrically connected to the servo motor 51 through wires. The CCD camera 31 adopts a camera of model WP-UT130, and the PLC controller 32 adopts a CQM1 controller. When the automobile hub to be sorted moves to the position below the CCD camera 31 inside the third mounting bracket 3, the CCD camera 31 detects a signal to take a picture of the automobile hub and compares it with the qualified automobile hub information stored in itself. When the automobile hub is unqualified, the CCD camera 31 transmits the signal to the PLC controller 32, and the PLC controller 32 will control the servo motor 51 to start.

[0028] As Figure 1 , Figure 3 and Figure 4 shown in the figure, a rotating shaft 61 is rotatably connected to the top of the second rotating seat 6. The top of the rotating shaft 61 is fixedly connected to a second baffle 62. Bearings 7 are embedded at the top of the second baffle 62 and the first baffle 43 near the right edge. A connecting shaft 71 is fixedly connected between the inner surfaces of the two bearings 7. A linkage plate 72 is fixedly connected between the tops of the two connecting shafts 71. The second baffle 62 is rotatably installed above the second rotating seat 6 through the rotating shaft 61. The two ends of the linkage plate 72 are rotatably connected to the first baffle 43 and the second baffle 62 through the connecting shaft 71 and the bearing 7 respectively, and the linkage plate 72 is perpendicular to the first baffle 43 and the second baffle 62. The four points of the rotating shaft 41, the rotating shaft 61 and the two connecting shafts 71 form a parallelogram. Therefore, when the rotating shaft 41 drives the first baffle 43 to rotate forward towards the first conveyor belt 12, the second baffle 62 will be driven to rotate synchronously under the action of the linkage plate 72, and the distance between the first baffle 43 and the second baffle 62 will contract, thereby restricting the defective hubs within a smaller range and blocking the subsequent high-quality hubs from passing through. At the same time, under the action of the second conveyor belt 14 continuously conveying the hubs to the right, the hubs will slide onto the first conveyor belt 12 along the surface of the first baffle 43 and be sorted out.

[0029] Usage method and working principle of this device: First, place the wheel hub on the second conveyor belt 14 in the assembly line. Subsequently, the PLC controller 32 controls the motors in the first conveyor belt 12 and the second conveyor belt 14 to run and drive the wheel hub to be conveyed to the right. When the wheel hub enters below the CCD camera 31 in the third mounting bracket 3, the CCD camera 31 detects the signal, takes a photo of the automotive wheel hub, and compares it with the qualified automotive wheel hub information stored in itself. When the automotive wheel hub is unqualified, the CCD camera 31 transmits the signal to the PLC controller 32. The PLC controller 32 will control the servo motor 51 to start. After the servo motor 51 starts, it will drive the second bevel gear 52 to rotate. At this time, the second bevel gear 52 will drive the first bevel gear 42, the rotating shaft 41, and the first baffle 43 to rotate forward. During the process, under the action of the bearing 7, the connecting shaft 71, and the linkage plate 72, the first baffle 43 will drive the second baffle 62 to rotate forward synchronously and guide the wheel hub towards the connecting inclined port 21. At this time, the continuously conveyed wheel hub to the right will be blocked by the inclined first baffle 43 and will gradually slide forward and move to the first conveyor belt 12 through the connecting inclined port 21 for rejection. The sorting operation of defective products is realized, which does not require manual participation, has a high degree of automation, can work continuously for a long time, and effectively improves the wheel hub sorting efficiency.
