[0002] Optical thin films refer to one or more thin films with specific optical properties (such as reflection, transmission and interference), usually made of transparent materials such as fluorides, oxides or polymers. Optical thin films are widely used in anti-reflective coatings, anti-reflection films, filters, mirrors, lasers and displays in optical devices.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-6 , an optical film thickness gauge, comprising a workbench 1, a first moving component 2 is arranged at the upper end of the workbench 1, at least two clamping mechanisms 3 are arranged at the upper end of the first moving component 2, the clamping mechanisms 3 are used to clamp the optical film, a second moving component 4 is also arranged at the upper end of the first moving component 2, a detection component 11 is arranged on one side of the second moving component 4, when used in the utility model, the optical film is placed on the first moving component 2 and fixed by the clamping mechanism 3, and then the detection component 11 is responsible for detecting the thickness of the optical film, and by operating the first moving component 2 and the second moving component 4, the thickness detection of different areas of the optical film can be realized, thereby improving the comprehensiveness and accuracy of the measurement;

[0026] Among them, the detection component 11 is connected to the second movable component 4 through a connecting mechanism 5, and the first movable component 2 and the second movable component 4 are driven by two driving mechanisms 6 respectively. In this embodiment, the two driving mechanisms 6 are respectively located on the first movable component 2 and the second movable component 4, and the two driving mechanisms 6 have the same structure. In the utility model, the connecting mechanism 5 can enable the detection component 11 to be quickly connected with the second movable component 4, which is convenient for disassembly, repair and maintenance.

[0027] Furthermore, the first moving component 2 includes a base 21, the upper end of the base 21 is fixedly connected to a slide rail 22, a slider 23 is slidably connected to the slide rail 22, and a moving platform 24 is fixedly connected to the slider 23. In the utility model, the moving platform 24 can slide smoothly on the slide rail 22, thereby realizing precise movement of the optical film in the horizontal direction, providing a stable measurement reference for the detection component 11.

[0028] Furthermore, the clamping mechanism 3 includes two mounting seats 31, and the mounting seats 31 are fixedly connected to the moving platform 24. A connecting shaft 32 is fixedly connected between the two mounting seats 31. A connecting arm 33 is rotatably connected to the connecting shaft 32, and a torsion spring 34 is fixedly connected to the connecting shaft 32. One end of the torsion spring 34 is fixedly connected to the connecting arm 33, and one end of the connecting arm 33 is also provided with a clamping block 35. In the present embodiment, the clamping block 35 is a rubber wheel. In the utility model, the connecting arm 33 is driven by the elastic force of the torsion spring 34, so that the clamping block 35 clamps the film. When the clamping mechanism 3 needs to be opened and the film needs to be removed, the connecting arm 33 can be manually rotated to make the clamping block 35 disengage from the film, so that the film can be easily removed.

[0029] Among them, the second moving component 4 includes a U-shaped frame 41, the lower end of the U-shaped frame 41 is fixedly connected to the upper end of the base 21, and a slide rail 2 42 is fixedly connected to one side of the U-shaped frame 41. The slide rail 2 42 is slidably connected to a connecting seat 43. In this embodiment, the connecting seat 43 moves laterally on the slide rail 2 42. In the utility model, the position of the detection component 11 is adjusted by moving the connecting seat 43, thereby realizing the thickness detection of different areas of the optical film.

[0030] In this embodiment, the driving mechanism 6 includes two fixed seats 61, and a screw rod 62 is rotatably connected between the two fixed seats 61. The screw rod 62 is driven by a motor 63. The lower end of the mobile platform 24 is fixedly connected to a connecting block 64. The two screw rods 62 are respectively threadedly connected to the connecting block 64 and the connecting seat 43. In the utility model, when the motor 63 drives the screw rod 62 to rotate, the linear motion of the mobile platform 24 and the connecting seat 43 on their respective slide rails can be accurately controlled through the action of the thread, thereby realizing the precise movement of the first moving component 2 and the second moving component 4, so as to perform thickness detection on different areas of the optical film.

[0031] In addition, the connecting mechanism 5 includes a sleeve shaft 51, which is fixedly connected to the connecting seat 43. A connecting column 52 is fixedly connected to one side of the detection component 11. Two arc-shaped clamping blocks 53 are arranged at one end of the connecting column 52. The connecting column 52 is inserted into the sleeve shaft 51. A clamping mechanism 54 is arranged in the sleeve shaft 51. The clamping mechanism 54 and the arc-shaped clamping block 53 are mutually clamped. In the utility model, the detection component 11 can be quickly connected or separated from the second movable component 4 through the mutual clamping of the clamping mechanism 54 and the arc-shaped clamping block 53, which greatly simplifies the maintenance and servicing process.

[0032] In addition, the clamping mechanism 54 includes two arc-shaped stop blocks 541, which are fixedly connected to the inner wall of one end of the sleeve shaft 51. The sleeve shaft 51 is slidably connected to two limit blocks 542. One end of the limit block 542 is fixedly connected to a spring 543. One side of the spring 543 is fixedly connected to the inner wall of the sleeve shaft 51. Slots are provided on both sides of the sleeve shaft 51. One end of the limit block 542 is fixedly connected to a shift block 544. The shift block 544 is located in the slot. When the connecting column 52 is inserted into the sleeve shaft 51 and rotated, the arc-shaped block 53 and the arc-shaped stop block 541 are engaged with each other, thereby fixing the connecting column 52. At the same time, the elastic force of the spring 543 pushes the limit block 542 so that the arc-shaped block 53 is tightly fixed in the sleeve shaft 51, ensuring the stable connection of the detection component 11. When disassembly is required, the shift block 544 is pulled to drive the limit block 542 to move backward, and then the connecting column 52 is rotated to separate the arc-shaped block 53 from the arc-shaped stop block 541, so that the detection component 11 can be disassembled.

[0033] Working mode: When in use, the optical film is placed on the mobile platform 24, and the connecting arm 33 is driven by the elastic force of the torsion spring 34, so that the clamping block 35 clamps the film. When it is necessary to open the clamping mechanism 3 and remove the film, the connecting arm 33 can be manually rotated to disengage the clamping block 35 from the film, so that the film can be easily removed. When the motor 63 drives the screw rod 62 to rotate, the linear motion of the mobile platform 24 and the connecting seat 43 on their respective slide rails can be accurately controlled by the action of the thread, thereby realizing the precise movement of the first moving component 2 and the second moving component 4. In order to detect the thickness of different areas of the optical film, when the connecting column 52 is inserted into the sleeve shaft 51 and rotated, the arc block 53 and the arc stop block 541 are engaged with each other, thereby fixing the connecting column 52. At the same time, the elastic force of the spring 543 pushes the limit block 542 so that the arc block 53 is tightly fixed in the sleeve shaft 51, ensuring the stable connection of the detection component 11. When disassembly is required, the shift block 544 is pulled to drive the limit block 542 to move backward, and then the connecting column 52 is rotated to separate the arc block 53 from the arc stop block 541, so that the detection component 11 can be disassembled.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
