Abstract
The invention provides a near-infrared nondestructive testing device for fruits. The device comprises a sample rack, a light source, a detector, an optical fiber and an optical fiber probe, wherein the sample rack is a columnar frame provided with a fruit placing table on the top; a through hole which is slightly smaller than a fruit is formed in the middle of the fruit placing table; a turbine lead screw lifter is arranged at the bottom of the frame; an optical fiber probe installation frame which is a hollow cylinder matched with the optical fiber probe in shape and with a first through slot on the side face is arranged on a lifting rod of the lifter; the width of the first through slot is greater than the wire diameter of the optical fiber; the optical fiber probe is erected on the top of the cylinder by virtue of a bump on the optical fiber probe; a hollow wedged block with a second through slot on the side face is arranged between the top of the cylinder and the bump; the hollow part of the wedged block is matched with the optical fiber probe in shape. The angle of the optical fiber is changed by way of arranging the wedged block on the optical fiber probe bracket, so that the problem that light is reflected by fruits is solved. The device provided by the invention is simple in structure, strong in practicality, low in cost and high in accuracy.
Description
Technical field
The invention belongs to infrared detection apparatus field, particularly relate to a kind of near infrared fruit the cannot-harm-detection device.
Background technology
Fruit Non-Destructive Testing, the pol of usual employing near infrared spectrum diffuse reflection to fruit detects, fiber-optical probe is all vertical irradiation fruit usually, light also can produce reflex through fruit occurs irreflexive while, will have an impact to result of detection once there is reflection, and then affect the accuracy of testing result, how to design a kind of minimizing and even avoid light to become the problem of those skilled in the art's research through the near infrared detection equipment of fruit back reflection.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of light that reduces through fruit back reflection degree and then the near infrared fruit the cannot-harm-detection device improving accuracy in detection.
For solving the problem, the technical solution used in the present invention: a kind of near infrared fruit the cannot-harm-detection device, comprise specimen holder and FT-IR spectrometer, described spectrometer comprises light source, detecting device, optical fiber and fibre-optical probe, the light that described light source sends enters fibre-optical probe through incident optical and is irradiated to fruit surface, the light that fruit surface reflects enters described detecting device through fibre-optical probe and reception optical fiber and carries out Treatment Analysis, described specimen holder is cylindrical frame, the top of described framework is provided with fruit mounting table, the middle part of described fruit mounting table has one for setting up fruit and being slightly less than the through hole of fruit size, the bottom of described framework is provided with a worm screw lifter, the elevating lever of described worm screw lifter is provided with a fibre-optical probe erecting frame, described fibre-optical probe erecting frame is the hollow cylinder with the side of described fibre-optical probe mating shapes with the first groove, the width of described first groove is greater than the wire diameter of described optical fiber, fibre-optical probe is set up in the top of described cylindrical shell by the boss on it, the voussoir that side has the second groove and hollow is provided with between described cylindrical shell top and described boss, the shape of voussoir hollow space and the mating shapes of described fibre-optical probe.
The angle of described voussoir and horizontal direction is 10-20 degree.
A rubber washer is provided with above described through hole.
On described fruit mounting table, the outside of through hole is provided with the block of outward-dipping setting in a week.
The advantage that the present invention has and good effect are: the present invention changes the angle of optical fiber by the mode arranging voussoir on fibre-optical probe support, and then the problem that solution light reflects through fruit, and structure is simple, and practical, cost is low, and accuracy is high; Elevating mechanism coordinates the convenient height adjusting cylindrical shell with cylindrical shell, and probe is put into cylindrical shell, can adjust probe and the distance of fruit simultaneously, ensure the accuracy of testing result further; The angle 10-20 degree of voussoir and horizontal direction farthest can reduce reflected light; Namely packing ring plays the effect of sealing to the surface reflection of light, reach again the object adapting to difformity fruit as a flexible support, the setting of block prevents fruit from falling.
