[0002] FPC flexible circuit boards are widely used in modern electronic products such as smart phones, wearable devices, automotive electronics, medical equipment and industrial control equipment due to their significant advantages such as light weight, thin thickness, small size, foldability and high circuit density. Therefore, the detection device for FPC flexible circuit boards has become particularly important and has become a key tool to ensure product quality and reliability.

[0003] A Chinese patent discloses an FPC flexible circuit board visual inspection device authorization announcement number CN220018360U.

By setting the fixing plate 7 to be made of rubber material, the FPC flexible circuit board can be prevented from being damaged during clamping, and the friction of the lower clamping plate 5 and the upper clamping plate 6 on the FPC flexible circuit board can be increased to prevent the FPC flexible circuit board from falling during the detection process. By installing a first spring 11 on one side of the fixing block 9, when the upper clamping plate 6 is closed, the elastic force of the first spring 11 can be used to bounce the fixing block 9 into the fixing groove 10, so that the FPC flexible circuit board can be suspended and fixed on the top of the base 1, so that the staff can directly detect the front and back sides of the FPC flexible circuit board, simplify the operation steps, and improve work efficiency.

[0025] Reference Figure 1-Figure 3As shown, in the present embodiment: an extension block 12 is fixedly connected to the bottom of the fixed block 9, and a baffle 13 used in conjunction with the extension block 12 is fixedly connected to the interior of the upper clamping plate 6. By installing the extension block 12 at the bottom of the fixed block 9 and installing the baffle 13 used in conjunction with the extension block 12 inside the upper clamping plate 6, the moving trajectory of the fixed block 9 can be restricted, effectively preventing the first spring 11 from being too elastic and causing the fixed block 9 to pop out from the interior of the upper clamping plate 6.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown, in the present embodiment: the sliding block 8 is internally slidably connected with a pressing block 14, the bottom of the pressing block 14 is fixedly connected with a trapezoidal block 15, and both sides of the bottom of the trapezoidal block 15 are slidably connected with moving blocks 16, and both sides of the interior of the sliding block 8 are provided with through grooves 17 that penetrate into the interior of the upper clamping plate 6 and are used in conjunction with the moving block 16. The trapezoidal block 15 is driven downward by pressing the pressing block 14, and the moving block 16 is squeezed to move toward the through groove 17, so as to achieve a fixing effect, thereby preventing the first spring 11 from shaking during inspection and causing the FPC flexible circuit board to fall off.

By fixing the two ends of the second spring 18 to the moving block 16, when the staff pulls up the sliding block 8, the rebound force of the second spring 18 can be used to pull the moving block 16 out from the inside of the through groove 17, thereby achieving the effect of releasing the limit.

[0028] Reference Figure 1 and Figure 6 As shown, in this embodiment: the other end of the rotating rod 3 is fixedly connected to the rotating block 19, and the inside of the rotating block 19 is slidably connected to the movable rod 20.

[0029] Reference Figure 1 and Figure 6 As shown, in this embodiment: one end of the movable rod 20 close to the support plate 2 is fixedly connected to the limiting block 21.

By providing the limit groove 22 used in conjunction with the limit block 21 on one side of the rotating rod 3, the FPC flexible circuit board can be rotated to a suitable angle, and the limit block 21 is inserted into the limit groove 22 to achieve fixation, thereby preventing the rotating block 19 from shaking and causing the staff to be unable to conduct a careful inspection.

[0031] Working principle: The user installs the upper clamping plate 6 inside the lower clamping plate 5, so that the staff can clamp the FPC flexible circuit board inside the lower clamping plate 5 and the upper clamping plate 6. By setting the fixing plate 7 to be made of rubber material, the FPC flexible circuit board can be prevented from being damaged during clamping, and the friction between the lower clamping plate 5 and the upper clamping plate 6 on the FPC flexible circuit board can be increased to prevent the FPC flexible circuit board from falling during the detection process. By installing the first spring 11 on one side of the fixing block 9, the elastic force of the first spring 11 can be used to bounce the fixing block 9 into the fixing groove 10 when the upper clamping plate 6 is closed, so as to prevent the FPC flexible circuit board from falling during the detection process. The FPC flexible circuit board can be suspended and fixed on the top of the base 1, so that the staff can directly detect the front and back of the FPC flexible circuit board, simplify the operation steps, and improve work efficiency. By installing the extension block 12 at the bottom of the fixed block 9 and installing the baffle 13 used in conjunction with the extension block 12 inside the upper clamping plate 6, the movement trajectory of the fixed block 9 can be restricted, effectively preventing the first spring 11 from being too elastic and popping out of the fixed block 9 from the inside of the upper clamping plate 6. By pressing the pressing block 14, the trapezoidal block 15 is driven to move downward, and the moving block 16 is squeezed to move toward the through groove 17. , so as to achieve a fixing effect, prevent the first spring 11 from shaking during inspection and cause the FPC flexible circuit board to fall off, by fixing the two ends of the second spring 18 to the moving block 16, so that when the staff pulls up the sliding block 8, the second spring 18 can be used to pull the moving block 16 out from the inside of the through groove 17 by the rebound force, so as to achieve the effect of releasing the limit, by installing a rotating block 19 at the other end of the rotating rod 3, and slidingly connecting the movable rod 20 inside the rotating block 19, so that the staff can rotate the lower clamping plate 5 and the upper clamping plate 6 by rotating the movable rod 20, more It is further convenient for the staff to perform multi-angle inspection on the front and back sides of the FPC flexible circuit board, and can provide users with a more comfortable usage experience. By installing a limit block 21 at one end of the movable rod 20 close to the support plate 2, the staff can be prevented from pulling the movable rod 20 out of the inside of the rotating block 19 with excessive force. By opening a limit groove 22 on one side of the rotating rod 3 for use with the limit block 21, the FPC flexible circuit board can be rotated to a suitable angle.
