[0003] The optical fiber 20 is threaded through the inside of the slider 32, and the optical fiber 20 forms an S-shaped bend by relying on the slider 32 and the support shaft cores 4. During the vibration process, the optical fiber 20 is subjected to long-term pulling, extrusion and wear, which easily damages the optical fiber 20 and reduces the service life of the optical fiber 20; the motor 1 drives the slider 32 through which the optical fiber 20 is threaded to move up and down through the cam 2 and the push block 31. There are many transmission elements, which not only cause large vibration energy loss and low energy transfer, but also increase the overall volume of the laser fiber vibration device, increasing the material and device costs.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] The core of the present invention is to provide a small laser fiber optic vibration device, which clamps and fixes the optical fiber by using an optical fiber pressing block, and presses the optical fiber pressing block by using an upper pressing plate in cooperation with a base, with a simple structure, convenient assembly, and improved service life of the optical fiber.

[0033] The small laser fiber optic vibration device provided by the present invention includes:

[0034] Optical fiber 10;

[0035] The optical fiber pressing blocks 20 are arranged at both ends of the optical fiber 10, and a wire groove for clamping and fixing the optical fiber 10 is arranged therein.

[0036] The flat motor 31 for providing vibration energy, and the optical fiber 10 is arranged closely against the upper end surface of the flat motor 31.

[0037] The control module connected to the flat motor 31 is used to control the working state of the flat motor 31.

[0038] The vibration platform includes an upper pressing plate 41 and a base 42. The base 42 is provided with an installation groove for installing the flat motor 31 and the control module. The upper pressing plate 41 and the base 42 are detachably connected to cooperate with pressing the optical fiber pressing block 20 tightly.

[0039] Please refer to Figure 2 , the optical fiber 10 is arranged closely against the upper end surface of the flat motor 31. In order to prevent the optical fiber 10 from shifting relative to the upper end surface of the flat motor 31, optical fiber pressing blocks 20 are arranged at both ends of the flat motor 31. The optical fiber pressing blocks 20 are used to fix and clamp the optical fiber 10 to prevent the optical fiber 10 from shifting or bending.

[0040] Considering the processing performance and material cost, the optical fiber pressing block 20 is usually made of silicone rubber material, which is soft and light, and can effectively protect the optical fiber 10 from being pulled and worn; a connecting groove penetrating through to the wire groove is arranged on one side of the optical fiber pressing block 20 to facilitate the optical fiber 10 to be loaded into the wire groove.

[0041] The flat motor 31 and the control module belong to the vibration control module of the optical fiber vibration device. Among them, the flat motor 31 is used to provide energy for the vibration of the optical fiber 10, and its volume is small, which is beneficial to saving the installation space; the control module is electrically connected or signal-connected to the flat motor 31 and is used to control the working state of the flat motor 31, and it is mostly arranged as a circuit board 32.

[0042] In order to limit the displacement of the optical fiber pressing block 20, the upper pressing plate 41 and the base 42 are connected by connecting parts such as fastening screws and connecting pins, and the optical fiber pressing block 20 is pressed tightly on the base 42 to form a vibration platform for protecting the optical fiber pressing block 20 and preventing the optical fiber pressing block 20 from shifting during vibration.

[0043] Similarly, in order to prevent the flat motor 31 and the control module from shifting during vibration, the base 42 is provided with an installation groove for installing the flat motor 31 and the control module, and the installation groove is used to limit the two of them.

[0044] The above installation groove can be a groove recessed on the upper end surface of the base 42, or can be surrounded by positioning edges protruding on the upper end surface of the base 42.

[0045] The specific shapes of the upper pressing plate 41 and the base 42 are not limited and can be set as rectangular, circular or any other geometric shape, as long as the two can cooperate to press the optical fiber pressing block 20 and effectively fix the vibration control module.

[0046] It should be noted that in order to expose the motor plug 33 of the flat motor 31 from the upper pressing plate 41, the upper pressing plate 41 is provided with a jack for the motor plug 33 to pass through, and the shape and size of the jack are adapted to the shape and size of the motor plug 33.

[0047] The flat motor 31 is mostly circular. The optical fiber 10 can pass through the center of the flat motor 31 or not. Preferably, the center of the flat motor 31 can be set in the vertical plane where the axis of the wire groove of the optical fiber pressing block 20 is located. At this time, the optical fiber 10 passes through the center of the flat motor 31, and the contact length and contact area between the optical fiber 10 and the flat motor 31 are the longest, and the vibration transmission efficiency is high.

[0048] In this embodiment, the optical fiber pressing block 20 is used to clamp and fix the optical fiber 10, and then the upper pressing plate 41 is used in cooperation with the base 42 to press the optical fiber pressing block 20, which can prevent the optical fiber pressing block 20 and the optical fiber 10 from shifting during vibration, thereby avoiding the problems of bending, extrusion and wear of the optical fiber 10, and being beneficial to extending the service life of the optical fiber 10;

[0049] The optical fiber 10 is arranged closely against the upper end surface of the flat motor 31. Through the coupling and close contact between the optical fiber 10 and the flat motor 31, the vibration transmission components such as cams are reduced, which not only reduces the vibration energy loss and improves the transmission efficiency, but also is beneficial to reducing the overall volume of the optical fiber vibration device, improving the space utilization rate, and reducing the material processing and device costs.

[0050] On the basis of the above embodiment, positioning step surfaces can be provided at both ends of the upper pressing plate 41 and both ends of the base 42, and the positioning step surfaces are in contact with the inner side surface of the optical fiber pressing block 20, so as to limit the optical fiber pressing block 20 in the optical fiber extending direction by using the positioning step surfaces.

[0051] It should be noted that the height of the positioning step surface of the upper pressing plate 41 and the height of the positioning step surface of the base 42 can be the same or different, but the two cannot be zero at the same time, otherwise it is difficult to effectively press the optical fiber pressing block 20 onto the base 42.

[0052] Considering the processing convenience and processing cost, usually the positioning step surfaces of the upper pressing plate 41 and the base 42 are located in the same vertical plane, which not only facilitates the simultaneous processing of the positioning step surfaces of the upper pressing plate 41 and the base 42, but also simplifies the structure of the optical fiber pressing block 20 and facilitates the processing of the inner side surface of the optical fiber pressing block 20.

[0053] In order to reduce the overall size and mass of the optical fiber vibration device, preferably, when the inner side surface of the optical fiber pressing block 20 abuts against the positioning step surface, the outer side surface of the optical fiber pressing block 20 can be flush with the end surface of the upper pressing plate 41 and the end surface of the base 42.

[0054] Compared with the case where the optical fiber pressing block 20 protrudes from the end surface of the vibration platform, it is beneficial to reduce the overall size and mass of the optical fiber vibration device; compared with the case where the optical fiber pressing block 20 is recessed from the end surface of the vibration platform, the contact area between the optical fiber pressing block 20 and the upper pressing plate 41 and the base 42 is increased, and the connection structure is more stable.

[0055] On the basis of the above embodiments, at least one bolt mounting hole can be provided on both the upper pressing plate 41 and the optical fiber pressing block 20, and at least one bolt connection hole is provided on the base 42. The fastening screw sequentially passes through the bolt mounting hole of the upper pressing plate 41, the bolt mounting hole of the optical fiber pressing block 20 and is threadedly connected with the bolt connection hole of the base 42, so as to connect the vibration platform and the optical fiber pressing block 20 and prevent the optical fiber pressing block 20 from shifting relative to the vibration platform.

[0056] Among them, the bolt connection hole can be set as a light hole or a through hole; the bolt connection hole needs to be set as a threaded hole that matches the fastening screw;

[0057] The number of fastening screws is determined by checking and calculating according to the design connection strength requirements in actual production. In order to effectively press the optical fiber pressing block 20, usually fastening screws are provided at the four corners of the vibration platform. It should be noted that the fastening screws should be at a certain distance from the wire groove of the optical fiber pressing block 20 to prevent the bolt connection hole of the optical fiber pressing block 20 from communicating with the wire groove.

[0058] In this embodiment, the upper pressing plate 41, the optical fiber pressing block 20 and the base 42 are sequentially connected by the fastening screws. Compared with only connecting the upper pressing plate 41 and the base 42, the fastening screws have a stronger pressing force on the optical fiber pressing block 20, and can more effectively prevent the optical fiber pressing block 20 from shifting relative to the vibration platform during vibration, and also facilitate the alignment of the optical fiber pressing block 20 and the vibration platform during assembly.

[0059] On the basis of the above embodiments, in order to prevent the vibration of the vibration platform from affecting the mass spectrometer, the base 42 can be connected to the support bottom plate 6 through at least one shock absorber 5, and the support bottom plate 6 is used to connect to the mass spectrometer.

[0060] The shock absorber 5 can be specifically set as a rubber shock-absorbing column, a shock-absorbing spring, etc. Its specific material, structure and size are determined according to the power and frequency of the flat motor 31 in actual production, so as to prevent the vibration energy from being transmitted to external devices such as the mass spectrometer and affecting the external devices.

[0061] For comprehensive consideration of the shock absorption effect and device cost, please refer to Figure 2, generally, shock absorbers 5 are provided at both ends of the support base plate 6 in the extending direction of the optical fiber, and the center lines of the two shock absorbers 5 and the axis of the optical fiber 10 are located in the same vertical plane.

[0062] In this specification, the various embodiments are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0063] The above has introduced in detail the small laser optical fiber vibration device provided by the present utility model.
