[0002] An optical thin film is a kind of optical dielectric material composed of thin layered dielectrics and propagating light beams through interfaces. In modern times, optical thin films have been widely used in the fields of optics and optoelectronics to manufacture various optical instruments. During the production and processing of optical thin films, in order to be applicable to different products, it is necessary to detect the thickness of the optical thin film with the help of a thickness detection device.

[0003] Most of the existing thickness detection devices are of fixed structures. First, the thin film is fixed, and then its thickness is detected by the thickness detection device. When it is necessary to detect the thickness of a local position of the optical thin film, the position of the thin film needs to be adjusted, and the fixing mechanism needs to be disassembled to adjust the position of the thin film, which is not convenient for adjusting the optical thin film. Summary of the Utility Model

A sliding column is fixedly arranged on one side of the movable sleeve. A fixing plate is sleeved outside the sliding column. An inclined groove is formed inside the fixing plate. A limiting pressing plate is fixedly arranged on the top of the movable sleeve.

[0007] Preferably, a motor is fixedly arranged on the top of the motor fixing seat, and the output end of the motor is fixedly connected with one end of the lead screw.

[0008] Preferably, the lead screw penetrates through both side walls of the detection seat and is connected with both side walls of the detection seat through bearings.

[0016] 2. When it is necessary to adjust the optical film, start the motor to reverse, so that the detection table moves out from the bottom of the thickness detector body. At the same time, the limiting pressing plate moves upward to release the limitation of the optical film on the top of the detection table, which is convenient for replacing the position of the optical film.

[0026] The limiting mechanism includes a lead screw 8. A threaded seat 9 is sleeved outside the lead screw 8. The lead screw 8 is threadedly connected to the threaded seat 9. The two ends of the threaded seat 9 are respectively fixedly provided with a detection table 10 and a connecting plate 12. Two through holes 11 are opened inside the detection table 10. Two limiting components are arranged on the top of the connecting plate 12. The limiting components include a vertical plate 13. A movable sleeve 14 is sleeved outside the vertical plate 13.

A limiting pressure plate 18 is fixedly arranged on the top of the movable sleeve 14;

[0027] In this embodiment, to facilitate the adjustment of the optical film, when the optical film needs to be adjusted, the motor 7 is started to reverse, so that the detection table 10 moves out from the bottom of the thickness detector body 2. At the same time, the limit pressing plate 18 moves upward to release the limit of the optical film on the top of the detection table 10, facilitating the replacement of the position of the optical film. At the same time, the detection table 10 moves away from the bottom of the thickness detector body 2, providing enough operating space for adjusting the optical film and improving the convenience of operation;

[0028] Among them, to control the moving direction of the detection table 10, the following technical solution is adopted in this device: A motor 7 is fixedly arranged on the top of the motor fixing seat 6. The output end of the motor 7 is fixedly connected to one end of the lead screw 8. The lead screw 8 penetrates through the two side walls of the detection seat 3 and is connected to the two side walls of the detection seat 3 through bearings. The rotation of the motor 7 drives the rotation of the lead screw 8. The rotation direction of the lead screw 8 is controlled by the rotation direction of the motor 7, and then the moving direction of the detection table 10 is controlled through the threaded seat 9;

[0029] Among them, to control the limit pressing plate 18 to limit the optical film, the following technical solution is adopted in this device: The connecting plate 12 is arranged on the top of the base 1 and is slidably connected to the top of the base 1. The vertical plate 13 is fixedly arranged on the top of the connecting plate 12. The top of the vertical plate 13 extends into the inside of the movable sleeve 14 and is slidably connected to the movable sleeve 14. The movable sleeve 14 penetrates through the through hole 11 and is slidably connected to the through hole 11. The sliding column 15 extends into the inside of the inclined groove 17 and is slidably connected to the inclined groove 17. Both ends of the fixing plate 16 are fixedly connected to the two side walls of the detection seat 3. When the detection table 10 moves the optical film conveyor belt to the bottom of the thickness detector body 2, at the same time, the connecting plate 12 moves to drive the movable sleeve 14 to move through the vertical plate 13. When the movable sleeve 14 moves, the cooperation between the sliding column 15 and the inclined groove 17 causes the movable sleeve 14 to move downward, and then the limit pressing plate 18 moves downward to cooperate with the detection table 10 to limit and fix the optical film.

[0030] The usage process of the present utility model is as follows: When using the present utility model, connect an external power supply, place the optical film on the top of the detection table 10, start the motor 7 to rotate forward. The rotation of the motor 7 drives the lead screw 8 to rotate. The rotation of the lead screw 8 drives the threaded seat 9 to move towards the bottom of the thickness detector body 2 through the thread. The movement of the threaded seat 9 drives the detection table 10 and the connecting plate 12 to move. The movement of the detection table 10 conveys the optical film to the bottom of the thickness detector body 2. At the same time, the movement of the connecting plate 12 drives the movable sleeve 14 to move through the vertical plate 13. When the movable sleeve 14 moves, the cooperation between the sliding column 15 and the inclined groove 17 causes the movable sleeve 14 to move downward, and further causes the limiting pressure plate 18 to move downward to cooperate with the detection table 10 to limit and fix the optical film. Similarly, when it is necessary to adjust the optical film, start the motor 7 to rotate in reverse, so that the detection table 10 moves out from the bottom of the thickness detector body 2. At the same time, the limiting pressure plate 18 moves upward to release the limit of the optical film on the top of the detection table 10, which is convenient for replacing the position of the optical film. At the same time, the detection table 10 is far away from the bottom of the thickness detector body 2, so that there is enough operating space when adjusting the optical film, improving the convenience of operation.
