Description
Technical Field
The utility model belongs to the technical field of superfine fiber detection, and particularly relates to a superfine fiber sensor.
Background
Microfibers are also called microfibers, fine denier fibers, and ultrafine fibers, and fibers having a denier of less than 0.3 denier (5 microns in diameter) are generally called microfibers. In the production of ultra fine fibers, it is often necessary to detect the position of individual fibers in order to determine whether the fibers are broken or whether the fibers are within a target area, particularly transparent ultra fine fibers, and it is more difficult to determine whether they are broken or are within the target area. The existing detection mode is to detect by using a correlation photoelectric switch, and when the fiber position is in the detection plane of the correlation photoelectric switch, the luminous flux changes, so that the fiber is proved not to be disconnected. However, the detection range is limited, and the fiber position cannot be detected in real time.
Disclosure of utility model
The utility model mainly aims to provide a superfine fiber sensor which can detect whether superfine fibers are broken or not and can detect the positions of the superfine fibers in real time.
The technical scheme adopted by the utility model is as follows:
a superfine fiber sensor comprises a box body, a light-emitting element, a linear CCD module and an amplifier;
The box body is of a totally-enclosed structure, and through holes with diameters slightly larger than those of the superfine fibers are respectively formed in the upper end and the lower end of the box body; the inner wall of the cavity of the box body is subjected to full-black non-reflective treatment (the inner wall of the cavity is subjected to non-reflective pure black treatment, and the more black and better are required), and the full-black non-reflective treatment is coating of the full-black non-reflective coating); the superfine fiber passes through the cavity through the through hole;
The light-emitting element is arranged in the cavity and is used for emitting light, so that the surface of the superfine fiber reflects light to form bright lines; the light emitted by the light-emitting element does not directly enter the detection surface of the linear CCD module;
The linear CCD module is arranged in the middle of one side wall of the cavity, the detection surface of the linear CCD module is perpendicular to the superfine fibers, and the linear CCD module is used for collecting reflection light formed on the surfaces of the superfine fibers and imaging the reflection light and outputting bright line position information;
The amplifier is arranged in the box body and is used for receiving the position information transmitted by the linear CCD module, amplifying the position information and transmitting the position information to an external control system.
Still further, the diameter of the through hole is 2-5 mm larger than the diameter of the ultrafine fiber.
In a further scheme, the light-emitting element and the linear CCD module are matched in model selection, namely: when the light emitting element is a visible light emitting element (LED light emitting tube), the linear CCD module is a visible light linear CCD module (a normal photosensitive type linear CCD module). When the light emitting element is an infrared invisible light element, the linear CCD module is an infrared invisible light linear CCD module (when the light emitting element is invisible light such as infrared light, the linear CCD module is also selected to have similar light detection capability).
In a further scheme, a lens is additionally arranged on the linear CCD module.
Still further, the light emitting element is packaged with a primary lens.
Still further, the purpose of the full black treatment is to reduce the influence of stray light on CCD imaging, so that the signal accuracy can be effectively improved, and the full black non-reflective treatment usually selects a pure black and light-absorbing material as a coating. The utility model adopts JS-Black Coating 01 series super-Black extinction Coating, and the super-Black extinction Coating can be used for stray light absorption and inhibition of an optical system, and can be used for optical components and baffles. Of course, the measures of the full black light-proof treatment can also comprise a light shield, a darkroom and other systems and parts needing to eliminate stray light.
The utility model also provides a superfine fiber position detection sensor which is formed by stacking two superfine fiber sensors, wherein one of the superfine fiber sensors axially rotates by 90 degrees, and the structure can detect the positions of the superfine fibers in the X direction and the Y direction simultaneously.
In the utility model, the inside of the box body is of a full-sealing structure except for the opening, so that external light is prevented from entering the cavity of the box body, and the detection accuracy is ensured. The linear CCD module is sensitive to the high-contrast image by using an imaging detection mode, and the signal output is the imaging projection position of the superfine fiber on the linear CCD module. The installation position of the amplifier is not strictly controlled, the light emitting element is not blocked from emitting light and the linear CCD is imaged, and the amplifier plays roles of signal analysis and output. The light emitting element may be a common visible light emitting device, or may be an infrared light emitting device or a light emitting device with other wavelengths, so long as the emitted light is ensured to reflect light on the superfine fiber and is consistent with the detection capability of the linear CCD module.
The utility model has the beneficial effects that:
The linear CCD module and the light-emitting element are arranged in the inner cavity of the fully-black box body to realize optical imaging of the superfine fibers, light emitted by the light-emitting element is reflected on the superfine fibers to form bright lines in the inner cavity of the fully-black box body, the positions of the bright lines with high contrast are detected by the linear CCD module and then transmitted to an external control system through the amplifier, so that whether the superfine fibers are broken or not can be detected, the positions of the superfine fibers can be detected in real time, and the device is particularly suitable for transparent superfine fibers;
the utility model has the advantages of simple structure, easy realization, reliable work and low cost;
the position detection of the superfine fiber is realized by adopting a low-cost visual imaging technology, and the requirement of an automatic control system is met;

The light-emitting element 2 is arranged in the cavity 7 and is used for emitting light, so that the surface of the superfine fiber 1 reflects light to form bright lines; and the light emitted by the light-emitting element 2 does not directly enter the detection surface of the linear CCD module 3. The linear CCD module 3 is arranged in the middle of one side wall of the cavity 7, the detection surface of the linear CCD module is perpendicular to the superfine fiber 1, and the linear CCD module is used for collecting reflection light formed on the surface of the superfine fiber 1 and imaging, and outputting bright line position information. In this embodiment, the light emitting element 2 and the linear CCD module 3 are matched in terms of model selection, and in this embodiment, when the light emitting element 2 is a visible light emitting element (LED light emitting tube), the linear CCD module 3 is a visible light linear CCD module (AMS/TSL 1401 CL).

Example 2
Referring to fig. 2, unlike example 1, the following is adopted: the linear CCD module 3 can be additionally provided with a lens, and the imaging of the superfine fiber in the sensor is ensured to be uniform and complete through the lens. When incomplete imaging is detected, the signal of the linear CCD module 3 changes, so that the superfine fiber break can be found.
Example 3
Unlike example 2, the following is: the primary lens is packaged in the LED luminous tube, so that light passing through the primary lens is prevented from directly irradiating the linear CCD module, and the luminous direction of the luminous element 2 is adjusted if necessary.

In the utility model, the detected superfine fiber 1 passes through the sensor through the through holes 6 at the two ends of the box body 4. When the hole size is appropriate, a small amount of external light entering the sensor is absorbed by the totally black non-reflective sensor, and no interference is generated to the linear CCD module 3.
