Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with Fig. 1, Fig. 2 to the present invention
It is described further.
A kind of continuous quasistatic of micro cable frees force measuring device, by industrial computer 1, acquisition and control system 2, moves
Make assembly and CCD camera 9 form,
Described action component includes bobbin 3, tension pick-up 4, length measurement sensor 5, tachogenerator 6, wire-arranging mechanism 7 and take-up
Wheel 8, described micro cable line bag is vertically installed on bobbin 3, and described tension pick-up 4 is positioned at the guide wheel freeing side, direction
Outer point be positioned on the axis of bobbin 3；
It is provided with 3 CCD camera 9 in the peripheral same level of described micro cable line bag；
Described acquisition and control system 2 one end is connected with industrial computer 1, and the other end is connected to wire-arranging mechanism 7 and 3
CCD camera.
Described 3 uniform settings of CCD camera 9.
The operation principle of this device is: micro cable line bag is arranged on bobbin 3, micro cable by tension pick-up 4,
Length measurement sensor 5, tachogenerator 6, wire-arranging mechanism 7 are finally wrapped on take-up pulley 8, and take-up mechanism is at computer control software
And according to given speed motion (freeing speed controlling between 200mm/min～500mm/min) under control system control, lead
Draw micro cable to free from line bag.
The present invention also provides for the method that a kind of micro cable continuous quasistatic tripping force is measured, and micro cable line bag is vertically put
Putting, micro cable is freed vertically, and bobbin axis and tension pick-up are positioned at the outer point phase of the guide wheel freeing side, direction
Cutting, micro cable line bag should meet h/r >=60 with the installation relation of tension pick-up simultaneously, the data recorded with tension pick-up
It is the axial tripping force of micro cable.
The principle of the present invention is: micro cable is axially freed, and in the case of micro cable elastic deformation is minimum, is ensureing line
Axle is tangent with the outer end points of tension pick-up guide wheel, and the installation relation of micro cable line bag and tension pick-up meet h/r >=
60, the error that installation site produces is reduced to try one's best, final guarantee micro cable is freed uniformly, now draws with in measurement optical cable
The method of power measures the tripping force of each circle being wrapped on bobbin indirectly, thus accurately measures axially freeing of micro cable
Power.Furthermore, it is understood that certain free resistance owing to the effect of binding agent is formed, thus by micro cable tensioning, do not considering
Under micro cable deformation, (owing to tripping force is the least and micro cable rigidity is the highest, micro cable deformation is the least, can neglect
Slightly), resistance balance freed by the tension force in micro cable and binding agent, and therefore micro cable tension force is micro cable tripping force,
Tripping force can be measured by tension pick-up.
Here the lodestar of measuring method is, owing to tripping force is the least, and the most only 30g, and the rigidity of optical cable is the highest,
Therefore the deformation work done stretching optical cable is negligible, so in the case of, use this device to ensure correct phase para-position
Putting, the pulling force in optical cable is the most equal with tripping force, so weighs tripping force by measurement pulling force.If being unsatisfactory for this
Kind of specified conditions, cable pulling force is also not equal to the tripping force of line bag, can not measure tripping force by this principle.Again just like
Fruit, it cannot be guaranteed that have enough distances between line bag and measurement wheel and free optical cable and measure tangent position, can not be drawn with measurement
The method of power measures the tripping force of line bag indirectly.
The length freeing micro cable involved in above method and free speed and have length measurement sensor respectively
Measure with tachogenerator.In order to measure the micro cable tripping force of whole line bag continuously, the capacity of take-up pulley should be greater than
The length of line bag micro cable, during freeing continuously, wire-arranging mechanism is according to freeing speed, micro cable diameter at computer
Control uniformly fitly will to free micro cable under the control of software to be wrapped on take-up pulley.
Tripping force, free speed, free length etc. the most respectively by corresponding sensor, A/D converter, control computer
And data processing software record is in a computer, and in graphical form Dynamic Announce on screen, it is simple to experimenter's is dynamic
State is monitored.
State of freeing and currently solution delamination and next the solution delamination freed one week to monitor micro cable to wrap from line
Whether surface has open defect, uses to shoot in 3 CCD camera of circumferencial direction installation and frees image.Thus can be at any time
Investigate the time of day freed, in order in time line bag surface defect detected and identify.
The above, only presently preferred embodiments of the present invention, it is not intended to limit protection scope of the present invention.
