The flatness detector detects the flatness of the gasket, and the flatness detection, defect detection and sorting are completed on a production line; this improves maintenance efficiency and quality, and achieves the effect of shortening the maintenance cycle of the EMU and reducing the maintenance cost of the EMU.

[0032] The above-described device will now be described in detail with reference to the accompanying drawings:

[0033] In a typical embodiment of this utility model, such as Figure 1 As shown, the automatic gasket detection and sorting device disclosed in this embodiment includes a vibrating feeder 1, a material conveying device 2, a cylinder 3, a material collecting device 4, a flatness detector 5, a defect detection device 6, a supplementary lighting device 7, and a flipping device 8.

[0034] The vibrating feeder 1 is located at one end of the linear feeder 9, and the other end of the linear feeder 9 is connected to the high position of an inclined transmission plate 11. The low position of the inclined transmission plate 11 is connected to the material conveying device 2. The material conveying device 2 includes a first material conveying device 21 and a second material conveying device 22. The height of the first material conveying device 21 is higher than that of the second material conveying device 22, and the end of the first material conveying device 21 overlaps with the beginning of the second material conveying device 22 in the horizontal direction.

[0035] A flipping device 8 is provided at the end of the first material conveying device 21, and the flipping device 8 realizes the flipping of the washer;

[0036] A flatness tester 5 is also provided between the linear feeder and the material conveying device 2 to test the flatness of the gasket; the flatness tester 5 is located above the inclined transmission plate 11.

[0037] A defect detection device 6 and a supplementary lighting device 7 are installed above both the first material conveying device 21 and the second material conveying device 22.

[0038] A number of cylinders 3 are provided on one side of the second material conveying device 22; a number of material collecting devices 4 are provided on the opposite side. The cylinders 3 push the gaskets into the corresponding material collecting devices 4.

[0039] Furthermore, a set of cylinders 3 can correspond to one material collection device 4, or one cylinder can correspond to one material collection device 4. The material collection device 4 can be set as a surface defect product collection device, a first thickness product collection device, a second thickness product collection device, etc., as needed.

[0040] Furthermore, the material collection device 4 includes a collection funnel 41 and a movable push-pull trolley 42; multiple trolleys are arranged sequentially on the other side of the second material conveying device 22, with one collection funnel corresponding to one trolley; the collection funnel is fixed on the support frame 10.

[0041] Furthermore, in order to fix and install the first material conveying device 21, the second material conveying device 22, the flatness detector 5, the defect detection device 6, the supplementary lighting device 7, and other equipment, a support frame is also provided. The first material conveying device 21 and the second material conveying device 22 are set inside the support frame, and the flatness detector 5, the defect detection device 6, and the supplementary lighting device 7 are fixed on the top beam or side column of the support frame, thereby realizing the fixation and installation of the first material conveying device 21, the second material conveying device 22, the flatness detector 5, the defect detection device 6, the supplementary lighting device 7, and other equipment.

[0042] Furthermore, the aforementioned vibrating feeder 1 centrally stores the washers to be sorted. The feeding mechanism at the bottom of the silo automatically feeds the vibrating plate, which then conveys the washers to the linear feeder via a spiral conveyor. The linear feeder arranges the washers in a straight line and transports them sequentially to the material conveying device 2. The cylinder 3 receives instructions from the PLC and pushes the washers to the corresponding material collection device 4. The material collection device 4 distinguishes washers of different thicknesses and diameters, as well as qualified and unqualified products.

[0043] Furthermore, the aforementioned flatness detector 5 is a 3D line laser sensor that detects the flatness and curvature of special washers. After the washers pass through the sensor, a 3D image is automatically generated, and the collected data is transmitted to the host computer. The washers are then screened using corresponding software algorithms, and the corresponding data is fed back to the PLC. The PLC system calculates the running time of defective products on the conveyor belt. When a defective product moves to a designated position, the corresponding cylinder actuates, pushing the defective product into the corresponding material collection device 4 for subsequent sorting. If the product is without defects, data on different thicknesses and diameters can be obtained. Then, when the corresponding product moves to a designated position, the corresponding cylinder actuates, pushing the corresponding product into the corresponding material collection device 4 for subsequent sorting.

[0044] Furthermore, the aforementioned defect detection device 6 uses two high-definition color industrial cameras, in conjunction with the supplementary lighting device 7, to acquire images of both sides of the gasket. The acquired image data is transmitted to a host computer, where the gaskets are screened using corresponding software algorithms to determine abnormalities such as damage, scratches, surface dirt, and marker residue. The corresponding data is then fed back to the PLC. The PLC system calculates the travel time of the defective product on the conveyor belt. When the defective product reaches the designated position, the corresponding cylinder actuates, pushing the defective product into the corresponding material collection device 4 for subsequent sorting.

[0045] Furthermore, the aforementioned flipping device 8 automatically flips the gasket to both sides, allowing the defect detection device 6 to detect defects on both sides. Specifically, the flipping device 8 is an arc-shaped guide plate installed at the end of the first material conveying device 21. See [link to relevant documentation]. Figure 4 This allows the washer to be flipped.

[0046] Furthermore, the existing belt conveyor devices for the first material conveying device 21 and the second material conveying device 22 have gasket guide plates 23 on both sides of the first material conveying device 21 to prevent the gasket from shifting during the conveying process; and gasket guide plates 24 on both sides of the second material conveying device 22 to prevent the gasket from shifting during the conveying process.

[0047] In this embodiment, the gasket is flipped by a combination of a first material conveying device and a second material conveying device with different heights and a flipping device. Then, a defect detection device is used to detect both sides, and a subsequent sorting device is used to sort the gaskets. A flatness detector is used to detect the flatness of the gaskets. Flatness detection, defect detection and sorting are completed on a single production line. This improves maintenance efficiency and quality, shortens the maintenance cycle of the EMU, and reduces the maintenance cost of the EMU.

[0050] Finally, it should be noted that relational terms such as first and second are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0051] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
