Description

Technical Field

[0001] This utility model relates to the technical field of image tube gain detection equipment, specifically a lifting and adjusting mechanism for image tube gain detection equipment. Background Technology

[0002] Image tube gain testing equipment is an instrument used to measure the gain performance of image intensifiers. Image intensifiers are the core components of direct-view low-light night vision systems, and their gain performance is an important indicator for measuring their quality and performance. When using this equipment, the detector needs to be driven by a lifting and adjusting mechanism to test the image tube.

[0003] A search revealed Chinese patent announcement number CN 114778083 A, which discloses a device for image tube gain testing, belonging to the field of image tube manufacturing and testing. The device aims to test incoming image tubes using a camera module, cabinet, monitor, parts tray, and automatic winding device. The light source conversion module is placed inside the cabinet. After the image tube is placed by a robotic arm, the automatic winding device installs a sleeve on the outside of the image tube. Light processed by the light source conversion module illuminates the image tube. A camera and image gain module then test the image tube illuminated by the processed light source. The gain test of the image tube is completed through these steps, and the real-time data detected by the camera is displayed on the monitor. Products that pass inspection are picked up by the robotic arm and placed in the qualified area, while products that fail inspection are placed in the unqualified area. This device optimizes the light source and designs an automatic winding device based on existing image tube gain testing equipment, improving testing accuracy and possessing significant practical value.

[0004] In the existing patent literature, the adjustment stage is moved in space, causing the inspection machine and the light shield to move above the workstation, so that the light shield completely covers the workstation. At this time, the light source conversion module, camera and image gain module inside the inspection machine work together to inspect the image tube. However, the adjustment stage has a complex structure and can only move vertically, and the movement direction is relatively simple. Therefore, it is necessary to propose a simple lifting and adjusting mechanism so that the inspection machine and the light shield can move freely. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figures 1-3 As shown, this utility model is a lifting and adjusting mechanism for a cathode ray tube gain detection device, comprising:

[0028] The testing assembly includes a mounting plate 12, a connecting plate 13, and a testing machine 14; the connecting plate 13 is screwed to one side of the top of the mounting plate 12.

[0029] The testing assembly also includes a frame 11 and a light shield 15; the mounting plate 12 is fixed to one side of the top of the frame 11, and the light shield 15 is fixed to the bottom of the testing machine 14;

[0030] The frame 11 is used to connect the mounting plate 12, the mounting plate 12 is used to connect the connecting plate 13, the connecting plate 13 is used to connect the fixing plate 21, and the inspection machine 14 and the light shield 15 are used together to inspect the image tube.

[0031] The adjustment assembly includes a guide rail 22, a moving block 23, a motor 26, a lead screw 27, and a connecting nut 28. The guide rail 22 is located above the connecting plate 13, the moving block 23 is slidably connected to the surface of the guide rail 22, the motor 26 is located above one side of the moving block 23, the lead screw 27 is located below the motor 26, and the connecting nut 28 is slidably connected to the surface of the lead screw 27.

[0032] The guide rail 22 is used for connecting and moving the movable block 23, the movable block 23 is used for connecting the fixed frame 25, the motor 26 is used to drive the lead screw 27, the lead screw 27 is used to move the connecting nut 28, and the connecting nut 28 is used to drive the testing machine 14 to move.

[0033] A fixing plate 21 is fixedly connected between the two ends of the guide rail 22 and the connecting plate 13, and a power block 24 is fixedly connected to the upper outer side of one side of the fixing plate 21.

[0034] The fixing plate 21 is used to fix the guide rail 22. The power block 24 is electrically connected to the guide rail 22 and the moving block 23. Both the guide rail 22 and the moving block 23 are equipped with coils. When the power block 24 is turned on, the coil generates an alternating magnetic field. Since the coil inside the moving block 23 is subjected to magnetic force in the magnetic field, the moving block 23 is pushed or pulled to move along the guide rail 22, thereby enabling the moving block 23 to move on the guide rail 22 by electricity.

[0035] A fixed frame 25 is fixedly connected to one side of the movable block 23. The motor 26 is fixed to the top of the fixed frame 25. The lead screw 27 is rotatably connected to the inside of the fixed frame 25. The top of the lead screw 27 is fixedly connected to the output end of the motor 26.

[0036] A connecting block 29 is fixedly connected to one end of the outer side of the connecting nut 28, and the other side of the connecting block 29 is fixedly connected to the testing machine 14.

[0037] The fixed frame 25 is used to connect the motor 26 and the lead screw 27, and the connecting block 29 is used to connect the nut 28 and the testing machine 14. The motor 26 drives the lead screw 27 to rotate through the output end, so that the lead screw 27 drives the connecting nut 28 to move up and down on its surface, causing the connecting nut 28 to drive the testing machine 14 to rise and fall through the connecting block 29.

[0038] Working principle: When the component is not in use, the power block 24 and motor 26 are not started. When the component is in use, the power block 24 is started, which causes the moving block 23 to move on the guide rail 22 through the power block 24. The moving block 23 drives the testing machine 14 to move laterally through the fixed frame 25, connecting nut 28 and connecting block 29. Then, the motor 26 is started, and the motor 26 drives the lead screw 27 to rotate through the output end. The lead screw 27 drives the connecting nut 28 to move up and down on its surface. The connecting nut 28 drives the testing machine 14 to move up and down through the connecting block 29. This allows the testing machine 14 to move both laterally and vertically, thereby expanding the movement range of the testing machine 14 and simplifying the structure of the original adjustment table.

[0039] Please see Figures 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] Auxiliary limit components;

[0041] The auxiliary limiting component includes a docking plate 31, a circular hole 32, and a vertical rod 33; the docking plate 31 is fixed on both sides of the connecting block 29, the circular hole 32 is opened at the opposite end of the docking plate 31, and the vertical rod 33 is inserted into the inside of the circular hole 32.

[0042] The mating plate 31 is used to open the circular hole 32, which is used to connect the vertical rod 33. The vertical rod 33 is used to limit the movement of the connecting nut 28.

[0043] A square hole 34 is provided on one side of the connecting plate 13. A set of sliders 35 are slidably connected inside the square hole 34. The top of the sliders 35 is fixedly connected to the bottom of the vertical rod 33.

[0044] The square hole 34 is used for the connection and movement of the slider 35. The slider 35 is used for the connection between the vertical rod 33 and the connecting plate 13. When the moving block 23 moves on the guide rail 22, the moving block 23 drives the vertical rod 33 to move through the fixing frame 25, the lead screw 27, the connecting nut 28 and the connecting block 29, so that the vertical rod 33 drives the slider 35 to move in the square hole 34, so that when the connecting block 29 moves vertically, the vertical rod 33 limits the vertical movement of the connecting block 29.

[0045] Working principle: When the components are not in use, the moving block 23 and the connecting block 29 do not move. When the moving block 23 moves, it drives the vertical rod 33 to move through the fixed frame 25, the lead screw 27, the connecting nut 28 and the connecting block 29. This causes the vertical rod 33 to drive the slider 35 to move within the square hole 34, causing the vertical rod 33 to follow the connecting block 29 to move laterally through the slider 35. When the connecting block 29 moves vertically, it drives the mating plate 31 to move on the surface of the vertical rod 33, thus limiting the vertical movement of the connecting block 29 and preventing the connecting block 29 from rotating with the connecting nut 28.
