Detailed Implementation

[0019] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Example: A DBC substrate production testing device, such as Figures 1-4 As shown, the device includes a testing box 1, an electric slide rail 3, an industrial camera 4, an X-ray detector 5, a heater 6, a clamping and flipping mechanism, a fixing rod 13, a protective door 14, a glass plate 15, a second bolt 17, and a controller 18. The upper part of the testing box 1 is longitudinally connected to the electric slide rail 3, and the industrial camera 4 is laterally slidably mounted on the electric slide rail 3. The X-ray detector 5 is fixed to the left and right sides of the industrial camera 4. The heater 6 is fixed to the rear side of the testing box 1 by bolts. The lower part of the testing box 1 is equipped with a clamping and flipping mechanism. The fixing rod 13 is welded to the left side of the front of the testing box 1, and the protective door 14 is rotatably connected to the fixing rod 13. The glass plate 15 is located in the middle of the protective door 14. The second bolt 17 is threadedly connected between the protective door 14 and the right side of the testing box 1. The controller 18 is located on the front of the testing box 1. The controller 18 is electrically connected to the electric slide rail 3, the industrial camera 4, the X-ray detector 5, and the heater 6.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the clamping and flipping mechanism includes a lower clamping plate 7, a block 8, a pull rod 9, an upper clamping plate 10, a first bolt 11, and a resistance probe 12. The lower clamping plates 7 are slidably rotatably connected to the left and right sides of the lower part of the detection box 1. A block 8 is fixed to one side of each of the two lower clamping plates 7. The blocks 8 are slidably connected to the detection box 1. A pull rod 9 is fixed to the left side of the left block 8. The upper clamping plate 10 is slidably connected to the upper part of the lower clamping plate 7. The upper clamping plate 10 and the lower clamping plate 7 are threadedly connected by the first bolt 11. The resistance probe 12 is inserted into the upper part of the upper clamping plate 10 and the lower part of the lower clamping plate 7. The block 8 will block the rotation of the lower clamping plate 7, and the sliding distance of the lower clamping plate 7 is greater than the sliding distance of the block 8.

[0022] likeFigure 1 、 Figure 2 and Figure 3 as shown, and further comprises a handle 16 and anti-skid pads 2, the handle 16 is fixed to the right side of the protective door 14, and the anti-skid pads 2 are arranged on the front and rear sides of the bottom of the detection box 1.

[0023] When it is necessary to detect the production of the DBC substrate, the device can be used. First, the staff needs to turn the second bolt 17 on the protective door 14, then open the protective door 14 clockwise, then place the DBC substrate between the two lower clamping plates 7, and rotate the first bolt 11 to move the upper clamping plate 10 downward to clamp and fix the DBC substrate, then reset the protective door 14 and the second bolt 17, and then the staff can observe the situation inside the detection box 1 through the glass plate 15.

[0024] Next, the appearance and bonding quality of the DBC substrate need to be detected. The staff needs to operate the controller 18 to start the industrial camera 4 and the x-ray detector 5. The industrial camera 4 will record the surface image of the DBC substrate, and integrate image processing algorithms such as edge detection, defect recognition and color analysis. It can automatically identify surface scratches, pits and protrusions and other defects. The staff only needs to observe and record. Then, the x-ray detector 5 will penetrate the DBC substrate with x-ray imaging technology and detect the internal structure and defects, so as to detect the bonding quality. During the detection process, the staff can control the electric sliding rail 3 to move the x-axis and y-axis positions of the industrial camera 4 and the x-ray detector 5 by operating the controller 18, so as to realize comprehensive and efficient detection of the DBC substrate and ensure that the product quality meets the standard.

[0025] Next, since the industrial camera 4 can only shoot one side of the DBC substrate, the other side will be blocked. In order to prevent incomplete detection, the staff can pull the pull rod 9 to the left side at this time. The lower clamping plate 7, the block 8, the pull rod 9, the upper clamping plate 10, the first bolt 11 and the resistance probe 12 connected therewith move to the left side. However, because the sliding distance of the lower clamping plate 7 is greater than that of the block 8, the block 8 will first separate from the detection box 1. At this time, the block 8 no longer blocks the rotation of the lower clamping plate 7. Next, the staff can rotate the pull rod 9 by 180 degrees to realize the turning of the DBC substrate. After turning, reset the block 8 and the pull rod 9 to make the block 8 block the rotation of the lower clamping plate 7 again.

[0026] Finally, the staff needs to detect the heat resistance and insulation performance of the DBC substrate. Only need to operate the controller 18 to start the heater 6 and the resistance probe 12 in turn, and observe and record whether there is a leakage. Thus, one round of DBC substrate production detection is completed. Repeat the above steps to continuously detect the production of the DBC substrate.

[0027] Finally, it should be explained that the above examples are only used to illustrate the technical solutions of the present application, but not to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
