[0050] In one embodiment of this utility model, such as Figure 6 As shown, the thickness of the product to be inspected 40 is equal to or slightly less than the opening length of the bearing groove 103 of the product fixing frame 10. When the product to be inspected 40 is loaded onto the product fixing frame 10, with the edge of the product to be inspected 40 placed in the bearing groove 103 of the product fixing frame 10, the product to be inspected 40 will not fall off during the flipping process.

[0051] In one embodiment of this utility model, such as Figure 6 As shown, multiple mounting holes are provided on the sides of the first frame edge 1011, the second frame edge 1012, and the third frame edge 1013 of the product fixing frame 10, as well as on the side of the lower frame 102. These mounting holes communicate with the bearing groove 103. A detection lighting lamp 30 is placed in one of the mounting holes, and the light emitted by the detection lighting lamp 30 is emitted from the groove 103 to illuminate the product under inspection from the side. Compared to illuminating the product from directly above, side illumination reduces reflection and results in a clearer image of the product. Furthermore, illuminating the product from all sides provides a clearer view of its internal structure.

[0052] In one embodiment of this utility model, such as Figures 1 to 3As shown, two support frames 20 are located on both sides of the product fixing frame 10. The second frame edge 1012 and the third frame edge 1013 of the product fixing frame 10 are respectively connected to the two support frames 20. The product fixing frame 10 and the support frames 20 are connected by a connecting pin 50. The top of the support frame 20 has a mounting ring 21. The connecting pin 50 is inserted into the mounting ring 21 and the product fixing frame 10 to connect the product fixing frame 10 and the support frame 20.

[0053] The following description uses the connection between the second frame edge 1012 and the support frame 20 as an example. The third frame edge 1013 is connected to the support frame 20 in the same way, which will not be elaborated further.

[0054] In one embodiment of this utility model, such as Figure 7 As shown, the outer side of the second frame edge 1012 has a pin hole 10121. A connecting pin 50 is inserted into the mounting ring 21 of the support frame 20 and the pin hole 10121 of the second frame edge 1012, connecting the support frame 20 to the second frame edge 1012. Further, the connecting pin 50 is fixedly connected to the second frame edge 1012, and cannot rotate in the pin hole 10121. The connecting pin 50 is movably connected to the support frame 20, and can rotate in the mounting ring 21, allowing the product fixing frame 10 to rotate and adjust its angle.

[0055] In one embodiment of this utility model, such as Figure 7 As shown, the mounting ring 21 has a first positioning hole 22 for engaging with the positioning pin 60 to fix the connecting pin 50. Further, the first positioning hole 22 may be located, for example, at the top or middle of the mounting ring 21.

[0056] In one embodiment of this utility model, such as Figure 8 As shown, the connecting pin 50 is cylindrical and has multiple second positioning holes 51. These second positioning holes 51 are arranged around the connecting pin 50. The multiple second positioning holes 51 can cooperate with the first positioning hole 22 and the positioning pin 60 to fix the product fixing frame 10 at a certain angle.

[0057] In one embodiment of this utility model, the positioning pin 60 is used to fix the connecting pin 50 to the mounting ring 21. When the first positioning hole 22 on the mounting ring 21 and a certain second positioning hole 51 on the connecting pin 50 are coaxial, inserting the positioning pin 60 into the first positioning hole 22 and the second positioning hole 51 can fix the connecting pin 50 to the mounting ring 21, so as to fix the product fixing frame 10 at a certain angle.

[0058] In one embodiment of this utility model, a groove 52 is provided on the connecting pin 50, and the groove 52 surrounds the connecting pin 50. A plurality of second positioning holes 51 are formed at the groove 52, and the presence of the groove 51 facilitates the insertion of the positioning pin 60 into the second positioning hole 51.

[0059] The product fixing frame 10 can be adjusted at multiple angles by means of multiple second positioning holes 51 on the connecting pin 50.

[0060] In one embodiment of this utility model, there are three second positioning holes 51, and the included angle between the central axes of two adjacent second positioning holes 51 is 45°. When the three second positioning holes 51 are respectively aligned with the first positioning hole 22, the posture of the product fixing frame 10 is horizontal, tilted at 45°, and vertical at 90°. By rotating the connecting pin 50, different second positioning holes 51 are aligned with the first positioning hole 22, and the product fixing frame 10 can be adjusted to 0° (horizontal), tilted at 45°, and vertical at 90°, so that the product to be inspected can be adjusted to be placed horizontally, tilted at 45°, or vertically, and the product to be inspected can be checked for defects from three angles.

[0061] It should be noted that there are no restrictions on the number of second positioning holes or the included angle between the central axes of two adjacent second positioning holes, and these can be adjusted as needed.

[0062] In one embodiment of this utility model, such as Figure 7 As shown, the locating pin 60 includes a pin body 61 and a pin cap 62. The diameter of the pin body 61 is equal to or slightly smaller than the diameter of the first locating hole 22 and the second locating hole 51, allowing the pin body 61 to be inserted into the first locating hole 22 and the second locating hole 51. The assembly of the pin body 61 with the first locating hole 22 and the second locating hole 51 adopts a clearance fit or a transition fit. The pin cap 62 is located at the end of the pin body 61, and the two are integrally formed. The diameter of the pin cap 62 is larger than the diameter of the first locating hole 22 and the diameter of the pin body 61. The presence of the pin cap 62 facilitates the removal of the locating pin 60 and also contributes to aesthetics.

[0063] When using the above-mentioned product carrier 100, adjust it to a horizontal position, open the lower frame 102 of the product fixing frame 10, insert the product to be inspected into the bearing groove 103 of the upper frame 101 of the product fixing frame 10, and then snap the lower frame 102 and the upper frame 101 together. When the angle needs to be adjusted, pull out the positioning pin 60, rotate the product fixing frame 10, adjust the product fixing frame 10 to the target angle, and insert the positioning pin 60 into the first positioning hole 22 on the mounting ring 21 and the second positioning hole 51 of the connecting pin 50 for fixation. Figure 9 A schematic diagram of a defect detection system according to an embodiment of the present invention is shown.

[0064] likeFigure 9 As shown, this utility model also relates to a defect detection system, including a product carrier 100, an operating table 200, a camera (not shown), and an image processing device 300.

[0065] The workbench 200 includes a work surface 201, a side wall 202, and a support structure 203 beneath the work surface 201. A lighting source is provided on the side wall 202 to illuminate the workbench.

[0066] The product carrier 100 is mounted on the worktable 201. A camera is mounted on the worktable 201 and located directly above the product carrier 100 for acquiring images of the product under inspection.

[0067] The camera is connected to the image processing unit 300, transmitting images of the product to the unit. The image processing unit 300 has built-in image processing software that detects defects in the product based on the images. The software includes AOI (Automated Optical Inspection) and AI (Artificial Intelligence) software. 80% of defects are detected by the AOI software initially, while defects that are difficult to identify or poorly defined are ultimately decided by the AI. The AI ​​can, to some extent, mimic human judgment, applying "rules of thumb" to image recognition, thus resolving the remaining 20% ​​of problems.

[0068] In one embodiment of this utility model, the image processing device 300 may be a computer, which is internally configured with image processing software, such as AOI software and AI software.

[0069] Using the product carrier 100, multi-angle image acquisition of the product under inspection can be achieved with the camera fixed, allowing for comprehensive defect detection from multiple angles. Furthermore, when adjusting the angle, the operator does not need to directly contact the product; instead, they adjust the product fixing frame of the product carrier 100, reducing the possibility of product contamination.

[0070] Optionally, the defect detection system may also include an illumination source, which is mounted on the side wall 202 of the worktable 200.

[0071] Optionally, the defect detection system also includes an air blowing device, which is installed on the side wall of the operating table 200 with the air outlet facing the product carrier 100 to prevent dust particles from falling onto the product surface during the inspection process. A filter is installed at the air outlet of the air blowing device to filter dust and prevent it from being blown onto the product surface.

[0072] Optionally, the defect detection system also includes a wind speed detection device, which is installed at the air outlet of the air blowing device to monitor the wind speed at the air outlet of the air blowing device and transmit the data to the image processing device 300 so as to adjust the wind speed.
