Embodiment
The utility model is further illustrated with reference to specific accompanying drawing.
A kind of closed-loop lithium battery core coil device described in the utility model, as Figure 1-3, mainly includes one
The supporting construction 15 that vertical panel is formed, is provided with let off roll 1 on the riser of supporting construction 15, and stock roll band is set in this position
Put, the connection of the rear end of let off roll 1 unreels servomotor 6, and it is unreeled and by itself calculating coil diameter side by the passive of starting stage
Formula carries out unreeling speed preset and regulation, while needs to be arranged on the driving operation of the winding servo-driver 8 on transverse slat；On riser
It is also equipped with rolling up pin 4 and the roller 3 that tests the speed, the connection of volume pin 4 end rolls up pin servomotor 13 by unreeling the driving operation of servo-driver 10,
Roll up pin servomotor 13 and form full closed loop control with outside speed measuring coder 11, given and regulation volume pin angular speed, it rolls up aciculiform
Shape is not fixed, and volume pin angular speed is according to the target linear velocity that logic controller 12 is set and the reality obtained by outside speed measuring coder
The difference of border linear velocity, compensation is adjusted with the execution cycle of μ s levels, while caused slight tension fluctuation passes through together in winding
Sample is arranged on the change in location buffering of the tension force swing rod 2 of riser side, likewise, the change in location feedback information of tension force swing rod 2
To the tension force swing rod servomotor 7 of connection in its back-end, collaboration swing rod servo-driver 9 drives operation, and provides data feedback,
Test the speed the outside speed measuring coder 11 that the end of roller 3 is set, and is connected on the swing rod encoder interfaces for unreeling servo-driver, structure
Into full closed loop control, default winding target linear velocity, actual winding linear velocity and data feedback are integrated, it is delicate using 250
The equipment reaction cycle, constantly follow regulation and control speed, in order to avoid with reduce velocity jump and bring tension force to damage the drawing of winding, erect
Set some middle transition rollers 5 to lengthen on plate and release tape length, slow down timely tension force.
During operation, coil of band material target length, and coiling material target linear velocity are preset by logic controller.Rate controlling mechanism
With semi-closure inscription of loop, preceding several cycle periods（That is starting stage, process time are less than 4ms）, it is default constant with one to roll up pin
Angular speed is run, it is therefore an objective to the primary data needed for generation system operation；Outside speed measuring coder detects the actual linear speed of operation
Degree；Rate controlling mechanism switches to fully closed inscription of loop, now because of volume aciculiform shape as winding process changes, it may occur that change, therefore it is real
Deviation just occurs in border linear velocity and preset linear velocity；Site error be multiplied by a proportionality coefficient obtain roll up needle speed give, should
Proportionality coefficient, it is different and different, it is necessary to be drawn by field adjustable repeatedly according to actual environment.It is given through pulleying pin to roll up needle speed
The internal closed loop of servo-driver, obtain new volume pin angular speed and give.Servomotor performs the angular speed and given, and then changes
The winding linear velocity on pin is rolled up, reaches and eliminates winding setting linear velocity and actual linear velocity error, realizes constant linear velocity operation
Purpose；Goal-selling linear velocity and actual linear velocity deviation, the tension variation on coil of band material surface is formed, after the sensing of tension force swing rod
Forming position changes, and unreels servomotor and follows regulation and control to unreel speed；As wrapup procedure is carried out, the coil of band material radius that unreels
Reduce therewith, the change in location now measured by outside speed measuring coder, with reference to the coding for unreeling servomotor and integrating in itself
The actual motion angular speed that device measures, current coil of band material radius can be calculated.And then servomotor is unreeled, according to rate controlling machine
The default winding target linear velocity of structure and actual coil diameter is currently unreeled, renewal is unreeled to fixed angular speed, to keep winding target
Linear velocity is consistent；When the winding physical length that outside speed measuring coder detects is equal to the winding target length of setting, ascend the throne
It is 0 to put error, and now winding terminates；
The utility model has abandoned limitation and the open loop control mode of CAM table, has passed through closed-loop without self study
Line speed feedback and regulation, quickly and easily complete conversion angular speed and reach volume needlework constant airspeed, be soft additionally, due to winding
Property material, under closed-loop winding state, when being skidded between external encoder and winding, may cause system driving,
And then system is damaged, the system is protected by design protection mechanism, is prevented from endangering, is illustrated in fig. 4 shown below：
Guarded by location：When winding work, meeting real-time detection practical position and target location, when physical location feedback and mesh
When the difference of cursor position exceedes the tracking error of default, system can report an error and out of service, ensure system safety with this；
Speed protection：When winding work, outside linear velocity and shaft end angular speed can be detected in real time, when the speed detected
Feedback is more than the scope set, or when actual speed direction and theoretical velocity in opposite direction, winding and system can report an error and stop
Only run.
