[0032] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.
[0033] like Figure 1 As shown, a device for detecting the inner cavity when the folding screen hinge is in a closed state according to the present embodiment includes a base plate 1, a clamping mechanism 4 is installed on the top surface of the base plate 1, and the clamping mechanism 4 clamps the product 10 in a folded closed state; camera assemblies 2 are respectively installed on the base plate 1 outside the two ends of the folding axis of the product 10, and the camera assembly 2 is fixed to the base plate 1 via an adjustable bracket 3, and the imaging end of the camera assembly 2 is facing the folding axis of the product 10.
[0034] During inspection, the product 10 is clamped and fixed on the clamping mechanism 4 in a folded and closed state, and the camera assembly 2 takes images of the folding axis of the product 10 from both sides, so that the inner cavity parameters can be obtained, thereby realizing the inspection of the inner cavity when the folding screen hinge is in the closed state.
[0035] In this embodiment, the product 10 is clamped and maintained in a folded and closed state by the clamping mechanism 4, so that the camera components 2 at both ends can take images independently, which helps to realize detection, effectively avoids the errors and inconsistencies caused by repeated clamping and the detection of the two ends, and effectively ensures the stability of detection.
[0036] After the two relatively rotating parts of the product 10 are folded upward and closed, they are fixedly clamped on the clamping mechanism 4, so as to keep the product 10 folded and closed in the clamped state; the rotation axis of the product 10 is horizontally arranged and located at the bottom, which is convenient for the external camera components 2 at both ends of the product 10 to take pictures.
[0037] like Figure 2 and Figure 3 As shown, the structure of the clamping mechanism 4 is as follows: it includes a support 41 installed on the bottom plate 1, and a clamping driving power 48 is installed on the side of the vertical plate 49 on the top surface of the support 41. The clamping driving power 48 pushes the clamping block 47 to move horizontally and clamp on both sides of the product 10 to achieve clamping and fixing of the product 10; it also includes a clamping driving power 45, and the clamping driving power 45 pulls the pressing block 44, and the pressing block 44 pushes the product 10 toward the vertical plate 49 to be pressed, so that the clamped product 10 remains in a folded and closed state.
[0038] A support plate 42 is also installed on the vertical plate 49. The support plate 42 is located below the product 10. The support plate 42 limits the height of the product 10, which is convenient for clamping by the clamping mechanism 4 and effectively ensures reliable imaging of the external camera components 2 at both ends, thereby ensuring smooth inspection.
[0039] In this embodiment, when the product 10 is clamped by the clamping mechanism 4, the lower end of the product 10 is supported and limited by the support plate 42, and the clamping driving power 48 clamps the two sides of the product 10 through the clamping blocks 47 on both sides. The pressing block 44 is pulled by the clamping driving power 45 to press the product 10 toward the vertical plate 49, thereby reliably clamping the product 10 while effectively ensuring that it remains in a folded and closed state, which is convenient for the synchronous imaging of the external camera components 2 at both ends.
[0040] The clamping driving power 48 includes double outputs located in the same horizontal direction and in opposite directions, and clamping blocks 47 are respectively installed at the ends of the double outputs, and the clamping blocks 47 extend to the side of the product 10.

[0042] The clamping driving power 45 is installed on the side of the vertical plate 49 opposite to the product 10. A push plate 46 is installed at the output end of the clamping driving power 45 vertically away from the vertical plate 49. Guide strips 43 are symmetrically installed at both ends of the push plate 46. The guide strip 43 vertically passes through the vertical plate 49 and a pressure block 44 is installed thereafter.
[0043] In this embodiment, the pressing driving power 45 works to drive the pressing block 44 to move toward or away from the product 10 and the vertical plate 49 via the push plate 46 and the guide bar 43 .
[0044] In this embodiment, the guide bar 43 and the vertical plate 49 or the vertical plate 49 fixing block form a sliding assembly structure; according to actual needs, the sliding assembly structure can also adopt a guide rail-slider structure to ensure reliable and smooth sliding.
[0045] In this embodiment, the pressing driving power 45 can be a linear driving power such as an existing standard air cylinder, electric cylinder, etc.
[0046] The camera assembly 2 includes a camera 21, a lens 22, and a prism 24 arranged in sequence from top to bottom, and a light source 23 is arranged in front of the horizontal light incident end of the prism 24; the lens 22 is mounted on the bottom end of the camera 21, and the prism 24 is mounted on the bottom end of the lens 22; the camera 21 and the light source 23 are both supported and installed on the adjustable bracket 3; thereby realizing the installation of the camera assembly 2 on the base plate 1.
[0047] In this embodiment, the camera component 2 can be selected and matched from existing standard products, and configured with corresponding image processing functions so as to obtain corresponding feature sizes from the image.

[0052] In this embodiment, the height of the light source 23 can be adjusted by moving the clamping sleeve 35 up and down relative to the guide rod 32 . After the adjustment, the clamping sleeve 35 is locked relative to the guide rod 32 .
[0053] The structure of the support frame 36 is as follows: it includes a back plate 361 installed on the side of the lifting seat 34 or the side of the clamping sleeve 35, and light rods 362 are installed perpendicular to the side of the back plate 361 at intervals. The two light rods 362 are commonly mounted with an adjustment plate 363.
[0054] In this embodiment, the position is adjusted by moving the adjustment plate 363 along the length direction of the optical rod 362, such as defined as adjustment in the X direction. After the adjustment, the adjustment plate 363 is locked relative to the optical rod 362, thereby adjusting the installation position of the camera 21 or the light source 23 in the X direction.
[0055] As for the camera 21 , the camera 21 is locked and fixed on the corresponding adjustment plate 363 via the support plate 1 211 . The adjustment plate 363 is provided with a long hole along the Y direction to adjust the installation position of the camera 21 in the Y direction.

[0058] The product 10 is folded and closed and placed on the support plate 42 of the clamping mechanism 4. The clamping driving power 48 works to clamp the product 10 from both sides via the clamping block 47. The pressing driving power 45 works to apply a force toward the vertical plate 49 to the product 10 via the pressing block 44, thereby effectively keeping the product 10 in a folded and closed state while clamping and fixing it. Then, the camera assemblies 2 on both sides each take an image of the rotation axis of the product 10 to obtain parameters.
[0059] In actual operation, Figure 6 As shown, by taking images with the camera assembly 2, the lengths at A, B, and C can be obtained, and then the angles between them can be obtained, thereby obtaining the internal area and the capacity-to-screen ratio; of course, in actual use, other data information in the image can also be obtained as needed.
