DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] Please refer to Figures 1 - 4, the present utility model provides the following technical solutions: An inspection device for a steel mesh fixture, including a box body 1, and further including: a support frame 2, a backlight panel 3, and a supplementary light tube 4.

[0043] Further, as shown by Figure 1 and Figure 2 In this embodiment, the support frame 2 is fixed to the top of the box body 1, and an optically flat transparent glass 21 is fixed inside the support frame 2. The backlight panel 3 is installed inside the box body 1, and the supplementary light tube 4 is fixed to the top surface of the backlight panel 3. After adopting the above solution, during use, the supplementary light tube 4 is connected to an electrical power source and powered on. The supplementary light is provided from below by the supplementary light tube 4. The cleaned steel mesh is placed on the optically flat transparent glass 21. The light generated by the supplementary light tube 4 can illuminate the steel mesh, making the inspection clearer. The staff can more clearly observe whether the mesh holes are cleaned, greatly improving the inspection efficiency and accuracy, and avoiding the occurrence of missed inspections.

[0044] It should be noted that the supplementary light tube 4 used in the present utility model is in a long and straight shape. In actual use, other shaped supplementary light tubes 4 can also be used, such as a circular ring-shaped supplementary light tube 4.

[0045] In addition, it should be supplemented that the inspection device of the present utility model further includes a manual switch for controlling the supplementary light tube 4. The manual switch is fixed on the box body 1 and is used to manually turn on or off the supplementary light tube 4.

[0046] Preferably, as shown by Figure 1 In this embodiment, it further includes: a flipping frame 5. The flipping frame 5 is hinged to one end of the support frame 2, and an optically convex transparent glass 51 is fixed inside the flipping frame 5. After adopting the above solution, during use, after the steel mesh is placed on the optically flat transparent glass 21, the flipping frame 5 is closed. The steel mesh is limited and protected by the flipping frame 5 and the optically convex transparent glass 51. In addition, the optically convex transparent glass 51 has a certain magnifying function. Through the optically convex transparent glass 51, the magnified steel mesh can be observed, and the inspection is more accurate.

[0047] It is worth noting that based on the inspection device of the present utility model, a vision detection system can also be installed on the top of the box body 1 to inspect the steel mesh, which can effectively improve the inspection speed and accuracy. However, because the inspection after cleaning the steel mesh is a simple task, although using the vision detection system is more beneficial, the cost is relatively high. If the cost is not a concern, it is preferably to use the vision detection system in cooperation with the inspection device of the present utility model to inspect the steel mesh.

[0048] Preferably, as shown by Figure 1 In this embodiment, it further includes: a handle 52. The handle 52 is fixed to the free end of the flipping frame 5. By providing the handle 52, it is easy to open and close the flipping frame 5.

[0049] Preferably, Figures 1 - 3 As shown, in this embodiment, it further includes an adjusting mechanism 9. The adjusting mechanism 9 is used to adjust the height of the backlight plate 3, and the adjusting mechanism 9 includes: a supporting plate 91, a moving rod 92, a flipping support rod 93, a bidirectional threaded rod 94, and a handwheel 96. The two supporting plates 91 are symmetrically distributed. The backlight plate 3 is fixed to the top of the supporting plate 91. The two moving rods 92 are symmetrically distributed in the box body 1. The two groups of flipping support rods 93 are symmetrically distributed. The top end of the flipping support rod 93 is hinged to the supporting plate 91, and the bottom end is hinged to the moving rod 92. The bidirectional threaded rod 94 is rotatably installed in the box body 1, and the bidirectional threaded rod 94 penetrates through the moving rod 92 and is connected to the moving rod 92 by screw thread engagement. One end of the bidirectional threaded rod 94 extends out of the box body 1, and the handwheel 96 is fixed on the extending end of the bidirectional threaded rod 94. When observing with the human eye, to avoid the influence of excessive light intensity on observation, a low-intensity supplementary light tube 4 is usually used. That is, the supplementary light tube 4 is preferably a soft light tube. However, the distance between the supplementary light tube 4 and the steel mesh will affect the clarity of illumination. Therefore, before inspection, the height of the supplementary light tube 4 is adjusted first. The adjustment process is as follows: First, place the sample on the optical flat transparent glass 21, then turn on the supplementary light tube 4 for illumination, and observe whether the mesh holes of the steel mesh are clearly visible. If the brightness is low, use the handwheel 96 to rotate the bidirectional threaded rod 94, so that the two moving rods 92 approach each other inward under the screw thread engagement, and at the same time drive the flipping support rod 93 to flip and move, and use the flipping support rod 93 to lift the supporting plate 91 to increase the height of the backlight plate 3 and reduce the distance between the supplementary light tube 4 and the optical flat transparent glass 21 until the mesh holes are clearly visible, that is, the adjustment is completed. <able>

[0050] Preferably, Figures 1 - 3 As shown, in this embodiment, the adjusting mechanism 9 further includes: a guide rod 95. The two guide rods 95 are symmetrically fixed in the box body 1, and the guide rod 95 penetrates through the moving rod 92.

The wing nut 10 is installed on the extending end of the threaded column 911 by screw thread engagement. After adopting the above solution, when installing the backlight plate 3, place the backlight plate 3 on the supporting plate 91, and make the threaded column 911 penetrate through the backlight plate 3, and then tighten the wing nut 10 on the extending end of the threaded column 911, and the stable installation of the backlight plate 3 can be achieved, which is convenient for installation, use and disassembly. After disassembling the backlight plate 3, the supplementary light tube 4 can be disassembled and assembled more safely.

[0052] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, it further includes: positioning columns 8. Four positioning columns 8 are fixedly arranged diagonally in the box body 1, and positioning holes 31 for the positioning columns 8 to penetrate are machined on the backlight plate 3.
