[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-Figure 2The utility model provides an embodiment: a LED screen brightness detection device with a positioning structure, including an operating table 1. First, the material to be detected is placed on the top of the operating table 1. A placement slot 2 is opened on the top of the operating table 1, and then the material is placed in the placement slot 2. Two threaded rods 3 are threadedly connected to the front and back sides of the operating table 1. A rotating plate 4 is fixedly connected to one side of the threaded rod 3. At this time, the rotating plate 4 is rotated according to the size of the material, and the threaded rod 3 is driven to move under the rotation of the rotating plate 4. A rubber plate 5 is fixedly connected to the other side of the threaded rod 3. At this time, the rubber plate 5 moves inward close to the material through the movement of the threaded rod 3.
[0025] Eight special-shaped grooves 6 are provided inside the front and back sides of the operating table 1, and adjustment components are provided inside the eight special-shaped grooves 6. The adjustment components include special-shaped columns 7 and springs 8. The outside of the special-shaped columns 7 is slidably connected to the inside of the special-shaped grooves 6, and one side of the special-shaped columns 7 is fixedly connected to the side of the rubber plate 5 close to the placement groove 2. The rubber plate 5 will drive the special-shaped columns 7 to move while moving, and the bottom of the rubber plate 5 is slidably connected to the bottom of the placement groove 2. One end of the spring 8 is fixedly connected to the outside of the special-shaped columns 7, and the other end of the spring 8 is fixedly connected to the inner wall of one side of the special-shaped groove 6. At this time, the spring 8 will be compressed inside the special-shaped groove 6 as the special-shaped columns 7 move. When the rubber plate 5 is in full contact with the material, the material can be fixed, thereby achieving the fixation of the material and being able to adapt to materials of different sizes.
[0026] Two support frames are fixedly connected to the left and right sides of the top of the operating table 1. The top of the four support frames is fixedly connected to a top plate, the bottom of the top plate is fixedly connected to an electric slide rail, the internal sliding connection of the electric slide rail is connected to a slider, and the bottom of the slider is fixedly connected to a detection head. The position of the detection head is then moved by the electric slide rail to detect the material, and the electric slide rail facilitates the movement of the detection head.
[0027] Reference Figure 1 and Figure 3 Two support plates 9 are fixedly connected to the front and rear sides of the operating table 1. The support plates 9 can support the air pump 10 to keep it stable. The air pump 10 is installed on the top of the support plates 9. After the detection is completed, the air pump 10 is started. The output end of the air pump 10 is fixedly connected to a connecting pipe 11. The other end of the connecting pipe 11 is arranged at the through holes on the front and rear sides of the operating table 1. Driven by the air pump 10, the gas enters the interior of the connecting pipe 11 and then enters the interior of the air inlet 14. Cavities 12 are opened inside the four corners of the middle part of the operating table 1.
[0028] An ejection assembly is provided inside the cavity 12, and the ejection assembly includes a blocking block 13, an air inlet 14, a limiting plate 15, a ejector rod 16 and a spring 17. The outside of the blocking block 13 is fixedly connected to the bottom of the cavity 12, and the air inlet 14 is opened inside the blocking block 13. The gas enters the cavity 12 through the air inlet 14. The outside of the limiting plate 15 is slidably connected to the inner wall of the cavity 12. The bottom of the ejector rod 16 is fixedly connected to the top of the limiting plate 15. When the gas enters the cavity 12, the gas will squeeze the limiting plate 15 upward, and the ejector rod 16 moves upward.
[0029] Spring 2 17 is sleeved on the outside of the push rod 16, one end of the spring 2 17 is fixedly connected to the top of the limit plate 15, and the other end of the spring 2 17 is fixedly connected to the top inner wall of the cavity 12. At this time, the spring 2 17 is compressed, and as the push rod 16 moves, the four corners of the material can be squeezed out, and the material can be quickly ejected, which is convenient for the staff to take out the tested material. The four corners of the bottom end of the operating table 1 are fixedly connected with support legs, which can increase the stability of the operating table 1 and prevent the bottom of the operating table 1 from directly contacting the ground.
[0030] Working principle: first, place the material to be tested on the top of the operating table 1, and then put it into the placement slot 2. At this time, rotate the rotating plate 4 according to the size of the material, and the rotation of the rotating plate 4 drives the threaded rod 3 to move. At this time, the rubber plate 5 moves inward and close to the material through the movement of the threaded rod 3. The rubber plate 5 will drive the special-shaped column 7 to move while moving. At this time, the spring 18 will be compressed inside the special-shaped slot 6 with the movement of the special-shaped column 7. When the rubber plate 5 is completely in contact with the material, the material can be fixed. Then, the position of the detection head is moved by the electric slide rail to detect the material. After the detection is completed, start the air pump 10. Driven by the air pump 10, the gas enters the inside of the connecting pipe 11 and then enters the inside of the air inlet 14. The gas enters the inside of the cavity 12 through the air inlet 14. When the gas enters the inside of the cavity 12, the gas will squeeze the limit plate 15 upward, and the push rod 16 moves upward. At this time, the spring 17 is compressed, and the four corners of the material can be squeezed out with the movement of the push rod 16.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
