Description

Technical Field

[0001] This utility model relates to the field of optical thin film production, and in particular to a quality inspection device for optical thin film production. Background Technology

[0002] Optical thin films are thin layers of material deposited on the surface of optical components using physical or chemical methods. They possess the ability to precisely control the propagation of light waves and effectively alter the reflection, transmission, absorption, and polarization properties of light. They are widely used in various optical systems, such as camera lenses, telescopes, eyeglasses, and display devices, significantly improving optical performance, reducing reflection loss, and enhancing color reproduction. During the production of optical thin films, to ensure their quality, tensile testing is typically performed using testing equipment to verify the film's mechanical properties and stability, thereby guaranteeing the product's lifespan.

[0003] However, in the existing technology, when using testing equipment to perform tensile tests on optical thin films, the thin films are prone to slipping off the fixed structure, which will undoubtedly affect the accuracy and reliability of the test results. Utility Model Content

[0004] The purpose of this invention is to provide a quality inspection device for optical thin film production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection device for optical thin film production, comprising an operating table and a connecting frame. The upper end of the connecting frame has a guide hole, a guide rod is slidably connected inside the guide hole, a guide rod is slidably connected inside the guide rod, a pressure plate is fixedly connected to the lower end of the guide rod, a short column is fixedly connected to the lower end of the pressure plate, a threaded column is fixedly connected to the middle of the upper end of the pressure plate, a rotating hole is opened at the upper end of the connecting frame near the guide hole, a rotating rod is disposed inside the rotating hole, a threaded sleeve is fixedly connected to the lower end of the rotating rod, and a turntable is fixedly connected to the other end of the rotating rod.

[0006] The operating table has an adjustment groove inside, and an electric push rod is installed inside the adjustment groove. One end of the electric push rod is fixedly connected to a moving block, and the upper end of the moving block is fixedly connected to a support plate. A scale block is provided at the upper edge of the operating table.

[0007] Preferably, a connecting seat is fixedly connected to the upper edge of the support plate, a locking hole is provided on one side of the connecting seat, and an installation block is movably connected inside the connecting seat.

[0008] Preferably, the inner wall of the mounting block is provided with a sliding groove, a slider is slidably connected inside the sliding groove, a sliding frame is fixedly connected to one side of the slider, a locking block is fixedly connected to the front side of the sliding frame, a fixing rod is fixedly connected inside the mounting block, and a spring is sleeved on the outside of the fixing rod.

[0009] Preferably, the threaded sleeve is rotatably connected to the connecting frame via a rotating rod.

[0010] Preferably, the number of short columns is multiple sets, and they are symmetrically arranged about the center line of the pressure plate.

[0011] Preferably, the slider slides inside the slide groove via a sliding frame, a telescopic rod, and a spring.

[0012] Using the above technical solution, by rotating the turntable, the turntable drives the rotating rod and the screw sleeve to rotate synchronously. Under the action of the internal thread of the screw sleeve, the threaded column and the pressure plate will move downward. At this time, the short column will tightly fit the upper end of the optical film, thereby realizing the limiting and fixing of the film. Similarly, by rotating the turntable in the opposite direction, the threaded column and the pressure plate will rise with it and release the limiting of the optical film. In addition, the setting of the guide rod and guide hole can greatly improve the stability of the pressure plate during lifting and lowering. The position of the pressure plate can be adjusted by components such as the rotating rod, screw sleeve, threaded column, and turntable, thereby making the short column firmly fix the optical film. The setting of multiple sets of short columns makes the film more evenly stressed during the pressing process, effectively avoiding the film slipping, and also improving the accuracy and reliability of the test results.

[0013] By using the above technical solution, pushing the locking block compresses the spring in the sliding frame. At this time, the locking block slides out from the inside of the locking hole, and the connecting bracket can be pulled upward to disassemble it. Similarly, during installation, the mounting block is slid in along the inside of the connecting seat. When the locking block reaches the position of the locking hole, the spring rebounds, causing the sliding frame to move in the opposite direction, and the locking block re-enters the locking hole, completing the limiting and installation of the connecting bracket. The connecting bracket can be quickly installed and disassembled through components such as the locking block, sliding frame, slider, fixing rod, and spring, which enables maintenance during long-term use and improves maintenance efficiency.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] Please see Figures 1-7 This utility model provides a technical solution: a quality inspection device for optical thin film production, including an operating table 1 and a connecting frame 2. The upper end of the connecting frame 2 is provided with a guide hole 3, and a guide rod 4 is slidably connected inside the guide hole 3. A guide rod 4 is slidably connected inside the guide rod 4. A pressure plate 5 is fixedly connected to the lower end of the guide rod 4. A short column 6 is fixedly connected to the lower end of the pressure plate 5. A threaded column 7 is fixedly connected to the middle of the upper end of the pressure plate 5. A rotating hole 24 is provided at the upper end of the connecting frame 2 near the guide hole 3. A rotating rod 8 is provided inside the rotating hole 24. A screw sleeve 9 is fixedly connected to the lower end of the rotating rod 8. A turntable 10 is fixedly connected to the other end of the rotating rod 8. An adjustment groove 11 is provided inside the operating table 1. An electric push rod 12 is provided inside the adjustment groove 11. A moving block 13 is fixedly connected to one end of the electric push rod 12. A support plate 14 is fixedly connected to the upper end of the moving block 13. A scale block 15 is provided at the upper edge of the operating table 1. The screw sleeve 9 is rotatably connected to the connecting frame 2 through the rotating rod 8.

[0025] Specifically, rotating the turntable 10 causes the rotating rod 8 and the screw sleeve 9 to rotate synchronously. Under the action of the internal threads of the screw sleeve 9, the threaded column 7 and the pressure plate 5 move downward. At this time, the short column 6 will tightly fit the upper end of the optical film, thereby limiting and fixing the film. Similarly, rotating the turntable 10 in the opposite direction causes the threaded column 7 and the pressure plate 5 to rise and release the limiting effect on the optical film. In addition, the guide rod 4 and the guide hole 3 can greatly improve the stability of the pressure plate 5 when it is raised and lowered. The position of the pressure plate 5 can be adjusted by the rotating rod 8, the screw sleeve 9, the threaded column 7, the turntable 10, etc., so that the short column 6 can firmly fix the optical film. The setting of multiple sets of short columns 6 makes the film more evenly stressed during the pressing process, effectively preventing the film from slipping, and also improving the accuracy and reliability of the test results.

[0026] Example 2

[0027] Please see Figures 1-7 This utility model provides a technical solution: a quality inspection device for optical thin film production. A connecting seat 16 is fixedly connected to the upper edge of the support plate 14. A locking hole 17 is opened on one side of the connecting seat 16. An installation block 25 is movably connected inside the connecting seat 16. A sliding groove 18 is opened on the inner wall of the installation block 25. A slider 19 is slidably connected inside the sliding groove 18. A sliding frame 20 is fixedly connected to one side of the slider 19. A locking block 21 is fixedly connected to the front side of the sliding frame 20. A fixing rod 22 is fixedly connected inside the installation block 25. A spring 23 is sleeved on the outside of the fixing rod 22. There are multiple sets of short columns 6, which are symmetrically arranged about the center line of the pressure plate 5. The slider 19 slides inside the sliding groove 18 through the sliding frame 20, the telescopic rod and the spring 23.

[0028] Specifically, by pushing the locking block 21, the sliding frame 20 compresses the spring 23. At this time, the locking block 21 slides out from the inside of the locking hole 17, and the connecting frame 2 is pulled upward to disassemble it. Similarly, during installation, the mounting block 25 is slid into the inside of the connecting seat 16. When the locking block 21 reaches the position of the locking hole 17, the spring 23 rebounds, causing the sliding frame 20 to move in the opposite direction. The locking block 21 then enters the locking hole 17 again, completing the limiting and installation of the connecting frame 2. The connecting frame 2 can be quickly installed and removed through components such as the locking block 21, the sliding frame 20, the slider 19, the fixing rod 22, and the spring 23, which enables maintenance during long-term use and improves maintenance efficiency.

[0029] Working Principle: When using this testing equipment, firstly, the two ends of the optical film to be tested are fixed inside the two sets of connecting frames 2. Specifically, rotating the turntable 10 causes the rotating rod 8 and the screw sleeve 9 to rotate synchronously. Under the action of the internal threads of the screw sleeve 9, the threaded post 7 and the pressure plate 5 move downwards. At this time, the short post 6 will tightly fit against the upper end of the optical film, thereby limiting and fixing the film. Similarly, rotating the turntable 10 in the opposite direction causes the threaded post 7 and the pressure plate 5 to rise and release the limiting effect on the optical film. In addition, the guide rod 4 and the guide hole 3 can greatly improve the stability of the pressure plate 5 when it rises and falls. The position of the pressure plate 5 can be adjusted through the rotating rod 8, screw sleeve 9, threaded post 7, turntable 10 and other components, thereby making the short post 6 firmly fix the optical film. The setting of multiple sets of short posts 6 makes the film more evenly stressed during the pressing process, effectively preventing the film from slipping, and also improving the accuracy and reliability of the test results. After fixing, start the electric push rod 12. The electric push rod 12 drives the moving block 13 to move to the left, thereby stretching the film. During this process, the staff can record the test results by observing the scale block 15. When it is necessary to repair the connecting frame 2 and its internal pressure plate 5, push the locking block 21. The locking block 21 causes the sliding frame 20 to compress the spring 23. At this time, the locking block 21 slides out from the inside of the locking hole 17. Pull the connecting frame 2 upward to disassemble it. Similarly, during installation, slide the mounting block 25 along the inside of the connecting seat 16. When the locking block 21 reaches the position of the locking hole 17, the spring 23 rebounds and causes the sliding frame 20 to move in the opposite direction. The locking block 21 enters the locking hole 17 again, completing the limiting and installation of the connecting frame 2. The connecting frame 2 can be quickly installed and removed through the components such as the locking block 21, sliding frame 20, slider 19, fixing rod 22, and spring 23, so that it can be repaired during long-term use and the repair efficiency can be improved.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
