Abstract
The invention discloses a kind of convergence testing agency automatically, mainly include that screw mandrel slide rail and acceleration detection module two parts are constituted.Screw mandrel slide rail is driven by servomotor, and acceleration detection module is mainly made up of acceleration transducer, spring, shell body, force transducer and end retaining part five part.Control servomotor rotating by the force transducer High power output small-signal in acceleration detection module, drive the rotation of screw mandrel slide rail screw mandrel, thus control the acceleration transducer on slide block and the tightening degree between product to be checked.The present invention controls to adjust in real time with situation change by Real-time Feedback force signal so that testing result has higher stability and accuracy, and mechanism structure manufactures and designs simple and reliable property height, it is adaptable to the on-line checking of melon and fruit quality streamline.
Description
Technical field
The present invention relates to a kind of convergence testing agency automatically, particularly relate to one and controlled by force signal and rely on private clothes electricity
The automatic convergence testing agency that machine drives.
Background technology
Along with the fast development of Automatic Measurement Technique, need the testing agency of a large amount of automatization badly and product is realized automatization exist
Line detects.Current detection technique and method have a lot, and scholar is engaged in Dynamic Non-Destruction Measurement research more in recent years, especially in regard to some
The online Dynamic Non-Destruction Measurement of melon and fruit quality, and these Dynamic Non-Destruction Measurements are applied relatively with acoustic vibration Characteristics Detection technology
Extensively.Acoustic vibration Characteristics Detection technology is mainly to one pumping signal of product to be checked, and recycling acceleration transducer collection is produced
The surface acoustic wave signal of product, by collecting a kind of Novel lossless detection skill that melon and fruit inside quality is judged by vibration signal
Art.It is required to during detection near exciting bank convergence product encourage, detects device convergence product surface appropriate location
Detect, and require that detection device can make adjustment in time during with detection environmental change.
Traditional method is that acceleration transducer is pasted onto melon and fruit surface, it is difficult to ensure that can be complete between sensor and melon and fruit
Full laminating, often falls off in test process, is difficult to again Aulomatizeted Detect.Current automated detection system needs one badly certainly
Dynamic convergence testing agency, when melon and fruit inside quality is done on-line checking, energy convergence melon and fruit surface automatically, and do not destroying melon
Really collection surface acoustic vibration signal in the case of surface quality.
Summary of the invention
The present invention proposes a kind of convergence testing agency automatically, solves the on-line checking difficult problem on product production line, passes through
Force transducer controls tightening degree during convergence, it is ensured that be adjacent to the in the same size of power every time, do not have the power of being adjacent to excessive time broken
Bad melon and fruit surface quality, or when the power that is adjacent to is too small, the acceleration transducer of collection surface sound wave can not be fitted completely with melon and fruit surface
Phenomenon.
The present invention is achieved by the following technical solutions.
A kind of convergence testing agency automatically, is made up of acceleration detection module and screw mandrel slide rail two parts, by servo electricity
Motivation drives screw mandrel to control the relative position of the acceleration detection module on slide block and product to be checked, in acceleration detection module
Force transducer controls the tightening degree between acceleration transducer and product to be checked.
Above-mentioned acceleration detection module is by acceleration transducer, spring, shell body, force transducer, end retaining part five
Part is constituted, and acceleration transducer is fixed on one end of spring, is formed by shell body and fixes spring, the spring other end with cavity
Clinging force sensor.
Above-mentioned acceleration transducer is the detection position of whole mechanism, the acoustic vibration signal after detection product excitation.
Above-mentioned force transducer, passes to the force signal on force transducer surface by gathering spring, controls servo-electric motor-driven
Make, it is achieved be close to degree during detection consistent every time.
Above-mentioned end retaining part is fixed on screw mandrel slide block by nut.
Above-mentioned screw mandrel slide block movement, by servomotor control, controls motor forward/backward rotation by force sensor signals, from
And control the relative position between acceleration detection module and detected product.

Detailed description of the invention
Illustrate further below in conjunction with the accompanying drawings:
When energized, controller is to servomotor (107) signal of telecommunication, and motor (107) starts to rotate forward, band movable wire
In bar slide rail, screw mandrel (105) rotates forward, and the slide block (104) on screw mandrel (105) drives acceleration detection module (103) to product to be checked
(102) close.Slowly close to product (102), when acceleration transducer (201) contact product (102) surface, acceleration detection
Spring (202) forced compression in module (103), now force transducer (204) detects the power that is adjacent to size when being adjacent to and feeds back
To servomotor (107), controlled the rotation of motor (107) by the force signal of feedback, thus adjust acceleration transducer
(201) with the relative position of product to be checked (102).
When being adjacent to power more than rated value, it is anti-that the force signal that force transducer (204) feeds back controls servomotor (107)
Turning, drive screw mandrel (105) reversion in screw mandrel slide rail, slide block (104) drives acceleration detection module (103) slowly away from product to be checked
Product (102), the decrement of the spring (202) in acceleration detection module (103) diminishes, and acceleration transducer (201) is with to be checked
Being adjacent to power between product (102) diminish, until being adjacent to power and nominal force is equal, servomotor (107) just stops operating.
When being adjacent to power less than rated value, the force signal that force transducer (204) feeds back just is controlling servomotor (107)
Turning, drive screw mandrel (105) in screw mandrel slide rail to rotate forward, slide block (104) drives acceleration detection module (103) slowly near product to be checked
Product (102), the decrement of the spring (202) in acceleration detection module (103) diminishes, and acceleration transducer (201) is with to be checked
The power that is slowly adjacent between product (102) becomes big, until being adjacent to power and nominal force is equal, servomotor (107) just stops operating.
