Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with Fig. 1, Fig. 2 to the present invention
It is described further.
A kind of micro cable is continuously quasi-static to free force measuring device, by industrial personal computer 1, acquisition and control system 2, moves
Make component and CCD camera 9 form,
The action component includes spool 3, tension sensor 4, length measurement sensor 5, velocity sensor 6,7 and of wire-arranging mechanism
Take-up pulley 8, the micro cable line packet are vertically installed on spool 3, are located on the tension sensor 4 and are freed direction side
The outer point of guide wheel is located on the axis of spool 3；
3 CCD cameras 9 are provided in the peripheral same level of the micro cable line packet；
Described 2 one end of acquisition and control system is connect with industrial personal computer 1, the other end be connected to wire-arranging mechanism 7 with
And 3 CCD cameras.
3 CCD cameras 9 are uniformly arranged.
The working principle of the present apparatus is：Micro cable line packet is set on spool 3, micro cable by tension sensor 4,
Length measurement sensor 5, velocity sensor 6, wire-arranging mechanism 7 are finally wrapped on take-up pulley 8, and take-up mechanism is in computer control software
It is moved under control system control according to given speed（Speed control is freed between 200mm/min~500mm/min）, lead
Draw micro cable to free from line packet.
The present invention also provides a kind of micro cable method that continuously quasi-static tripping force measures, micro cable line packet is vertically put
It sets, micro cable is freed along axial direction, and spool axis is located at the outer point phase for freeing the guide wheel of direction side with tension sensor
It cuts, while the installation relation of micro cable line packet and tension sensor should meet h/r >=60, the data measured with tension sensor
The as axial tripping force of micro cable.
The principle of the present invention is：Micro cable is axially freed, and in the minimum situation of micro cable flexible deformation, is guaranteeing line
The outer end point of axis and tension sensor guide wheel is tangent, and the installation relation of micro cable line packet and tension sensor meet h/r >=
60, it is final to guarantee that micro cable is uniformly freed to minimize the error of installation site generation, it is drawn at this time in measurement optical cable
The method of power to measure the tripping force for each circle being wrapped on spool indirectly, so that the axial direction for accurately measuring micro cable is freed
Power.Furthermore, it is understood that due to the effect of binder formed it is certain free resistance, so that micro cable is tensioned, do not considering
Under micro cable deformation（Due to tripping force very little and micro cable rigidity is very high, and micro cable deforms very little, can neglect
Slightly）, tension and binder in micro cable free resistance balance, therefore micro cable tension is micro cable tripping force,
Tripping force can be measured by tension sensor.
Here the lodestar of measurement method is, due to tripping force very little, generally only 30g, and the rigidity of optical cable is very high,
Therefore the deformation work done for stretching optical cable can be ignored, and in such situation, guarantee correctly opposite position using the present apparatus
It sets, the pulling force in optical cable is equal in size with tripping force, measures tripping force by measurement pulling force in this way.If being unsatisfactory for this
Kind specified conditions, cable pulling force and the tripping force for being not equal to line packet, cannot measure tripping force with this principle.Again just like
Fruit cannot be guaranteed to have enough distances between line packet and measurement wheel and free optical cable and measure tangent position, can not be drawn with measurement
The method of power to measure the tripping force of line packet indirectly.
It the involved length for freeing micro cable and frees speed in above method and has length measurement sensor respectively
It is measured with velocity sensor.In order to continuously measure the micro cable tripping force of entire line packet, the capacity of take-up pulley be should be greater than
The length of line packet micro cable, during continuously freeing, wire-arranging mechanism is according to freeing speed, micro cable diameter in computer
Controlling, which uniformly will fitly free micro cable under the control of software, is wrapped on take-up pulley.
Tripping force frees speed, frees length etc. then respectively by corresponding sensor, A/D converter, control computer
And data processing software record is in a computer, and in graphical form Dynamically Announce on the screen, convenient for the dynamic of experimenter
State monitoring.
It wraps to monitor micro cable from line to free one week and frees state and current solution delamination and next solution delamination
Whether surface has obvious shortcoming, frees image using 3 CCD cameras are installed in circumferencial direction to shoot.It thus can be at any time
The time of day freed is investigated, so that line packet surface defect is detected and identified in time.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
