[0024] In one embodiment, such as Figures 1-3 As shown, a PCB copper layer thickness detection device includes:

[0025] Rack 1;

[0026] Inspection station 2 is located on the upper surface of frame 1;

[0027] The multi-frequency probe array 3 is equipped with multiple sets of multi-frequency probes and is positioned above the detection station 2.

[0028] Control panel 4 is located on one side of rack 1;

[0029] A rotating assembly is used to drive the multi-frequency probe array 3 to rotate and is disposed on the multi-frequency probe array 3. The rotating assembly includes a support plate 5, which is disposed above the multi-frequency probe array 3, and a rotating component is disposed between the support plate 5 and the multi-frequency probe array 3.

[0030] The rotating component includes a rotary motor 6, which is mounted on the upper surface of the support plate 5. The output end of the rotary motor 6 passes through the support plate 5 and is connected to a rotating rod 7. A rotating plate 8 is mounted on the lower end of the rotating rod 7. The rotating plate 8 is connected to the multi-frequency probe array 3. An annular groove 9 is mounted on the upper surface of the rotating plate 8. Two sets of sliders 10 are slidably mounted inside the annular groove 9. A first vertical rod 11 is mounted on the upper surface of each set of sliders 10. A first fixing block 12 is mounted on the upper surface of each set of first vertical rods 11. A connecting plate 13 is mounted on each set of first fixing blocks 12. A second fixing block 14 is mounted on the other end of each set of connecting plates 13. A second vertical rod 15 is mounted on the lower surface of the second fixing block 14. The lower surface of the second vertical rod 15 is mounted on the upper surface of the support plate 5.

[0031] Specifically, in use, the workpiece is placed on the inspection station 2, and the multi-frequency probe array 3 performs thickness detection on the workpiece. Then, the rotary motor 6 is started, which drives the rotating rod 7 to rotate. The rotating rod 7 drives the rotating plate 8 to rotate, which in turn drives the multi-frequency probe array 3 to rotate. This allows the multi-frequency probe array 3 to perform omnidirectional thickness detection on the workpiece, improving the accuracy of thickness detection. By setting up a rotating assembly consisting of a support plate 5 and rotating parts, the multi-frequency probe array 3 can be driven to rotate, enabling it to perform multi-directional thickness detection on the workpiece. This improves the accuracy of workpiece thickness detection, avoids the problem of not being able to perform omnidirectional thickness detection, and reduces the accuracy of workpiece thickness detection, thus improving the efficiency of workpiece thickness detection.

[0032] like Figures 1-3 As shown, a circular block 16 is provided on one side of the support plate 5, an electric push rod 17 is provided on the lower end surface of the circular block 16, and a movable plate 18 is provided on the lower end surface of the electric push rod 17; the height of the multi-frequency probe array 3 can be adjusted by setting the electric push rod 17.

A threaded rod 20 is provided on the inner wall of the fixed frame 19, one end of which is connected to the output end of the rotating motor 21, which is mounted on one side wall of the fixed frame 19. A threaded block 22 is threadedly fitted on the outer side of the threaded rod 20, and the threaded block 22 is connected to the movable plate 18. An X-ray calibration workpiece 23 is provided on one side of the upper end face of the movable plate 18. The position of the workpiece can be detected by the X-ray calibration workpiece 23, and the rotating motor 21 can be started. The rotating motor 21 drives the threaded block 22 to move through the threaded rod 20, so that the threaded block 22 can drive the movable plate 18 to move, thereby making the multi-frequency probe array 3 located above the workpiece, which is quite convenient.

[0034] The above embodiment discloses a PCB copper layer thickness detection device. In use, the workpiece to be detected is placed on the detection station 2, and then the multi-frequency probe array 3 detects the thickness of the workpiece. Then, the rotary motor 6 is started, which drives the rotating rod 7 to rotate. The rotating rod 7 drives the rotating plate 8 to rotate, which in turn drives the multi-frequency probe array 3 to rotate. This allows the multi-frequency probe array 3 to perform omnidirectional thickness detection on the workpiece, improving the accuracy of the thickness detection. At the same time, the position of the workpiece can be detected by calibrating the workpiece 23 with X-rays. The rotary motor 21 can be started, and the rotary motor 21 drives the threaded block 22 to move through the threaded rod 20. The threaded block 22 can then drive the moving plate 18 to move, thereby positioning the multi-frequency probe array 3 above the workpiece, which is quite convenient.
