Description

The closed loop tension control system that motor coil twines
Technical field
The utility model relates to the tension control system field, relates in particular to the closed loop tension control system that a kind of motor coil twines.
Background technology
The average-sized motor stator coil generally is to turn to fusiformis with lenticular wire, spread and being shaped after wrapping.Lead will keep certain tension force in the winding process, otherwise lead winding displacement relative position on framework can't guarantee.Wire tension does not allow to surpass pulling force allowable under the peak acceleration situation.
Bobbin loader is the indispensable corollary equipment of motor coil wire coiling machine, is mainly used in the placement of drum.The structure of wire coiling machine bobbin loader, different because of the different motor coil process, single head horizon plate rail, multi-piece horizontally bobbin loader, single head vertical curve plate rail etc. are arranged.For compactness that guarantees the motor coil coiling and the inertia rotation of shutting down drum midway, bobbin loader should have suitable brake gear.
According to the technique for coiling of motor coil, the braking mechanism of bobbin loader, needing on the one hand provide certain tensile force to lead, prevents that on the other hand wire coiling machine from shutting down the inertia of drum midway and rotating.The tensile force of lead is a relative fixed value, different leads, and the tensile force that needs is different.This just requires the stop mechanism of bobbin loader, and variable lock torque can be provided.
In the manufacturing process of motor shaping winding (multiturn coil); The manufacturing process of motor shaping winding (multiturn coil) is the coiling operation of the important motor coil during motor is produced, and electromagnetic wire must, pulsation-free coiling stretching with suitable tightening force on wire coiling machine in the coiling.Tightening force is excessive, the electromagnetic wire tensile deformation, and the wire insulation film maybe be impaired; Tightening force is too small, and electromagnetic wire draws not straight, and it is bad to be pasted platform by the coiling turn-to-turn, and it is poor that the coil section size is stuck up.In this process, must guarantee that also the wire insulation film does not receive mechanical damage simultaneously.Therefore, the coiling of coil was directly connected to compactness and conformability and the single-piece heat-sinking capability and the insulating power of electromagnetism spare during motor electromagnetic spare was processed.
At present, domestic still having adopted flat winding technologe of traditional lenticular wire tread flaking and the manual winding equipment that falls behind more than many enterprises.
Along with the development of electromechanics trade, various novel conductive wires are more and more stricter to the requirement of laying tension, and at present simple Tension Control mode can't satisfy industry requirement, and major defect is the tension force that can not provide little; Adopt open loop control can't realize the constant tension of drum from the dishful to the tray better.
The tension control method that at present has been widely used in the motor coil winding process has following three kinds:
1. clamping plate are controlled method.Lead slides in clamping plate fully, by regulating the size that forcing screw comes pilot tension force.The realization simple in structure, easy of this method.If do not consider the wearing and tearing of clamping plate contact surface, can think that in whole winding process, wire tension is constant.The shortcoming of this method is that the lead wearing and tearing are more serious, especially to enamel wire, when friction force is big, may abrade the insulating barrier that coat of paint has destroyed lead.
2. utilize the preceding horizontal line wheel double as tenslator of coiling.During use, regulate the tightening screw of part horizontal line wheel, make the horizontal line wheel speed slack-off by increasing friction force.Because do the horizontal line time spent merely, each horizontal line wheel all can freely rotate, and at this moment the friction force of lead on wheel can be ignored.After the rotation of part horizontal line wheel was obstructed, lead certainly led to slide relative on wheel, and lead will receive the effect of friction drag, and wire tension is increased.This method does not need to establish in addition tenslator, and after setting up, in whole winding process, tension force all is constant.But weak point remains between lead and horizontal line wheel and produces slide relative, and lead is worn.
3. drag lock control method.Draw drum is coaxial to rotate together, and axle head is fixed a brake wheel.Can change the position that adds the force on the lever according to the size of required tension force during use, promptly change the arm of force, act on the friction force on the brake wheel thereby changed brake shoe.Like this, the velocity of rotation of control draw drum has also just been controlled laying tension.The advantage of this method is lead any member generation slide relative of getting along well, and the insulating barrier of lead is protected.But, because lead is constantly emitted from drum, the effective radius of drum is constantly reduced, so the inevitable constantly increase of the tension force of lead.It is thus clear that it is coarse that this simple dependence friction resistance moment is controlled tension force,, can not solve the variation issue of wire tension in the controlling process though it can apply a constant friction force to draw drum.
Conclude above-mentioned several kinds of tension control methods, all belong to the open loop Tension Control.Though can an initial tension be provided to lead, the tension variation that in winding process, possibly occur, said apparatus is all uncontrollable.
The utility model content
The utility model is to the Tension Control of the four-head horizon plate rail unwrapping wire of motor coil wire coiling machine, utilize electromagnetic power brake as brake gear, utilize the tension force detecting sensor to detect tension force, with the closed loop tension control system of the supporting composition of automatic tension controller.
For realizing above purpose; The technical scheme that the utility model adopts: the closed loop tension control system that a kind of motor coil twines is characterized in that: it comprises electromagnetic power brake (1), draw drum (2), arrangement stacking apparatus (3), tension force detecting sensor (4), equalizer bar (5), strip on edge winding machine (6), automatic tension controller (7), revolution display instrument (8) and electrical control cabinet (9); Its characteristic also is: an end of described draw drum (2) rotating shaft is installed an electromagnetic power brake (1); Draw drum (2) the right is equipped with arrangement stacking apparatus (3); On arrangement stacking apparatus (3), tension force detecting sensor (4) is installed; Tension force detecting sensor (4) output signal is connected with automatic tension controller (7), and automatic tension controller (7) is connected with electromagnetic power brake (1); Arrangement stacking apparatus (3) the right is equipped with equalizer bar (5), and equalizer bar (5) the right is equipped with strip on edge winding machine (6).
In the present invention, an elastic element is set on the described arrangement stacking apparatus (3), adorns the guide wheel that an ability is freely rotated on the described elastic element.
The beneficial effect of the utility model: the disadvantage of electromagnetic wire " soft do sclerosis " has been avoided in (1).
(2) reduced electromagnetic wire and contacted link, guaranteed that effectively the electromagnetic wire insulation film does not receive mechanical damage with mechanical device.
(3) owing to pull tight power and directly act on the electromagnetic wire drum, when wire coiling machine in running order, when stopping suddenly, avoided in the past drum since inertia is rotated further that caused electromagnetic wire gets loose thus electromagnetic wire knotting or line between the hard phenomenon of wiping of squeezing.
