Description

Technical Field

[0001] This application relates to the field of glass bead detection technology, and in particular to a glass bead defect detection module. Background Technology

[0002] A glass bead defect detection module typically includes a storage bin for glass beads to be tested, ensuring a sufficient sample supply during the testing process, and a feeder that transports the glass beads from the storage bin to the detection module one by one. The detection module performs surface inspection on the glass beads and transmits the test results to the module for analysis.

[0003] A search revealed that publication number CN215866741U discloses a detection module. The detection module's transmission motor is connected to a transmission motor connector. Two tension screws are mounted on the connector, with their shanks pressing against the side of the transmission motor's support plate. Tightening the screws causes the connector and the transmission motor to move outwards (away from the support plate), thereby driving the detection module's drive pulley to move in the same direction, tightening the transmission belt and increasing tension. An auxiliary tensioning pulley is mounted on the driven pulley to increase the belt's meshing area, maintaining tension and preventing tooth skipping, ensuring smooth transmission.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Common glass bead inspection devices only serve to steadily transport the beads. However, due to the limited vision of the inspection machine, although it can identify edges and contours in the image, it cannot accurately identify some subtle or complex defects in the rolling glass beads. Factors such as lighting, shadows, and reflections during the image acquisition process may affect the image quality, making the defects less obvious or difficult to identify. Furthermore, this device is not suitable for batch inspection and its practicality is generally limited. Utility Model Content

[0039] This application discloses a glass bead defect detection module. (Refer to...) Figures 1 to 7 The glass bead defect detection module includes a guide bracket 1, an inclined feeding platform 2, a glass bead guide plate 3, a horizontal collecting plate 4, a defect detection component 5, an adjustment component 6, and a pushing component 7. The guide bracket 1 is fixedly connected to the top outer side of the inclined feeding platform 2, the glass bead guide plate 3 is slidably connected to the top of the inclined feeding platform 2, the horizontal collecting plate 4 is fixedly connected to the bottom outer side of the inclined feeding platform 2, the defect detection component 5 is installed above the inclined feeding platform 2, the adjustment component 6 is installed on the bottom inner side of the inclined feeding platform 2, and the pushing component 7 is installed on the top of the horizontal collecting plate 4.

[0040] The guide bracket 1 is used to transport glass beads in the storage bin to the inclined loading platform 2. The glass bead guide plate 3, together with the adjustment component 6, is used to approach the glass beads and limit the rolling path of the glass beads. The horizontal collection plate 4 is used to support the pushing component 7. The pushing component 7 is used to repeatedly push the glass beads along the X-axis. The defect detection component 5 is used to capture the rolling image of the glass beads on the inclined loading platform 2 and the horizontal collection plate 4 and convert the image into a digital signal for classification and identification.

[0041] The defect detection component 5 includes a support frame 51, an industrial camera 52, and an edge detection module 53. The industrial camera 52 is installed inside the support frame 51, and the input interface of the edge detection module 53 is connected to the signal output interface of the industrial camera 52 via a connecting cable.

[0042] The adjustment assembly 6 includes a geared motor 61, a drive shaft 62, and a fine grinding disc 63. The motor shaft of the geared motor 61 is fixedly connected to the bottom of the drive shaft 62 via a coupling. The middle part of the fine grinding disc 63 is fixedly connected to the top of the drive shaft 62, and the outer wall of the fine grinding disc 63 abuts against the bottom surface of the glass bead guide plate 3.

[0043] The top of the glass bead guide plate 3 is also provided with a telescopic frame 8 and a compression spring 9. The compression spring 9 is installed inside the telescopic frame 8, and the two sides of the telescopic frame 8 are fixedly connected to the top surface of the glass bead guide plate 3.

[0044] The inner side of the glass bead guide plate 3 is also provided with several sets of equally spaced rubber rollers 10.

[0045] The pushing assembly 7 includes an electric telescopic rod 71, a connecting rod 72, a material box 73, and an L-shaped connecting plate 74. The electric telescopic rod 71 is threadedly connected to the top side of the horizontal material collection plate 4. The connecting rod 72 is installed on the outside of the output end of the electric telescopic rod 71 and is fixedly connected to the surface of the material box 73. The L-shaped connecting plate 74 is fixedly connected to the outside of the material box 73.

[0046] The edge detection module 53 is provided in several groups, and the several groups of edge detection modules 53 are arranged at equal intervals above the glass bead guide plate 3.

[0047] A feeding plate 11 is also provided above the material box 73. The feeding plate 11 is fixedly connected to the bottom of the inclined loading platform 2, and the length of multiple feeding plates 11 increases sequentially along the output direction of the electric telescopic rod 71.

[0048] The usage process of the glass bead defect detection module in this embodiment is roughly as follows:

[0049] Glass beads from the storage bin are poured into the inclined loading platform 2 via the guide bracket 1, ensuring the beads slide smoothly into the inspection area. Based on the glass bead specifications and inspection requirements, the position of the glass bead guide plate 3 is adjusted using the adjusting component 6 to ensure it closely fits the glass beads and restricts their rolling path. The industrial camera 52 and edge detection module 53 in the defect detection component 5 are activated, ensuring the system is in a ready-to-inspection state. During inspection, as the glass beads slide from the inclined loading platform 2 onto the glass bead guide plate 3, they are guided by the rubber roller 10 and cushioned by the compression spring 9, allowing them to roll stably into the inspection area. The industrial camera 52 captures the rolling images of the glass beads on the inclined loading platform 2 and the horizontal collection plate 4, and transmits the image signals to the edge detection module 53. The edge detection module 53 digitizes the received image signals and uses classification and recognition algorithms to determine if the glass beads have defects. If a glass bead is determined to be defective, it can be manually removed by the operator; otherwise, it continues rolling onto the horizontal collection plate 4. At this time, the electric telescopic rod 71 in the push assembly 7 is activated, pushing the material box 73 to move repeatedly along the X-axis direction via the connecting rod 72, ensuring that each glass bead has a chance to be captured by the industrial camera 52. The industrial camera 52 captures the rolling image of the glass bead, and the edge detection module 53 performs digital processing on the image, determining whether the glass bead has defects through classification and recognition algorithms. The algorithm detection of this device calculates the gradient magnitude and direction of each pixel in the image, and achieves this through convolution operations. It uses an operator to convolve with the image, and performs non-maximum suppression processing based on the gradient calculation to refine the edges. This is achieved by comparing the gradient values ​​of each pixel with its neighborhood, retaining only the local maximum points in the gradient direction. Finally, the equidistant arrangement of multiple sets of edge detection modules 53 ensures the comprehensiveness and accuracy of the detection.

[0050] The beneficial technical effects of the glass bead defect detection module in this application are roughly as follows:

[0051] The defect detection component 5 of this device can capture images of the glass beads during the rolling process and convert them into digital signals for classification and identification, thereby achieving accurate detection of glass bead defects. The glass bead guide plate 3 and the adjustment component 6 work together to adjust according to different specifications and types of glass beads, ensuring the stability and accuracy of the glass beads during the detection process. Furthermore, the pushing component 7 can repeatedly push the glass beads along the X-axis on the horizontal collection plate 4, ensuring that each glass bead has a chance to be captured by the defect detection component 5, thus improving the comprehensiveness and reliability of the detection.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
