Described conductor 8, for example, institute measured length lead two is connected with the joint 7a of stator 2 with chuck, and coil 11 is connected into the closed-loop path by formalizing attitude.That is, the coil 11 of stator 2 is to have under the situation of a coil formation, and the pair of joint 7a at the two ends of coil 11 and conductor 8 each chuck connect, and make coil 11 at the closed-loop path state.
In addition, shown in Fig. 4 (a), stator 2 has two coil 11 occasions, and being connected in series with the joint 7a of two conductors 8 and each coil 11 makes two coils 11 at closure state.As shown in Fig. 4 (b), stator 2 has the occasion of the coil 11 more than three, uses with the corresponding conductor 8 of the number of coil 11 and contacts with it, makes coil 11 all at the closed-loop path state.
As the conductor 8 between the joint 7a that connects (short circuit) coil 11, not only can adopt two ends that the lead of chuck is arranged, can also adopt copper pipe, copper coin etc. to make the structure of the loading and unloading connection fittings more more convenient than welding.In addition, at least equal powered-on capacity to be arranged with the conductor of coil 11 for conductor 8, for the rotation to stator do not impact set for as far as possible on the length short.
In addition, as shown in Figures 1 and 2, in the through hole 11a of the coil 11 of stator 2, for example, an end of coil (top of figure) 11b place, resin discharge nozzle 13 can freely be installed from shell 9 tops.This resin discharge nozzle 13 for example, installs and fixes simultaneously with robotic arm with the resin discharge, is connected with resin discharger 14.
When making motor 5b and stator 2 be in rotary state with the control signal of described control device 6,14 actions of resin discharger make and place institute's allocation (example in the shell 9, the end 11b of coil 11) resin discharge nozzle 13 is discharged resin to the 11a inner face, and the end 11b at the coil 11 of heated condition is smeared by resin like this.Resin fusion under the temperature of coil 11 enters each winding wire gap and fixing.
Then, the example with heater 1 action explains.
At first, stator 2 is stated from the swivel plate 5a, makes the bottom of the fastening stator 2 of clamp structure 5c, will heat appropriate location among the through hole 11a that the coil of wire 3 inserts coils 11 simultaneously by motor 5d.Under this state, will with the corresponding conductor 8 of joint 7a number of the shell 9 of stator 2 and the closed-loop path state that coil 11 is connected into setting.The occasion that at this moment a plurality of coils 11 are arranged is connected each coil 11 with conductor 8 between the joint 7a of deciding direction at coil 11.
After setting conductor 8 and coil 11 for the closed-loop path state, for example, after no illustrated heater switch ON operation in the control device 6, heat the coil of wire 3 from the electric current inflow of frequency that higher-order of oscillation machine 4 decide.After the heating coil of wire 3 medium-high frequency electric currents feed, magnetic flux change is arranged, produce induced current in the coil 11, because of this induced current, coil 11 is heated.In addition, the induced current that produces in the coil 11 flows in the closed-loop path of coil 11, and electric current produces Joule heat in coil 11 thus, and coil 11 is heated.That is, to supply with the high-frequency current of heater wire volume 3, coil 11 produces induced current with self heating while, and coil 11 is heated according to the Joule heat that this induced current produces.Because induced current is a high frequency, so coil 11 is heated effectively.
In addition, to the heating coil of wire 3 supply high frequency electric currents simultaneously, control device 6 sends control signal to motor 5b, makes motor 5b rotation, thus swivel plate 5a and and swivel plate 5a on stator 2 also decide rotating speed and rotate by institute.Because of the rotation of stator 2, the heating coil of wire 3 changes along through hole 11a circumferencial direction in order also with respect to the inner face of the through hole 11a of coil 11, induced current also at circumferencial direction along becoming.Therefore, along with the rotation of stator 2, coil 11 all is heated equably at circumferencial direction.
Then, give fixed heating time after, for example, control signal according to control device 6, make resin discharger 14 action, have insulating properties and fixed resin sprays to the end winding 11b of coil 11 from resin discharge nozzle 13, the end winding 11b of heated coil 11 is sprayed by resin.The spraying of this resin also is to carry out under swivel plate 5a rotation status, and at this moment, the heating coil of wire 3 is in the state of "on" position or outage can.And when the upper and lower end parts 11b of stator 2 blown resin, the realization that moves up and down of an available resin ejection nozzle 13 also can respectively established a resin ejection nozzle 13 up and down, once sprays in heating.
After quantitatively resin is sprayed at the end 11b of coil 11, resin ejection nozzle 13 stops to discharge resin (the heating coil of wire 3 is de-energized), swivel plate 5a stall, clamp structure 5c unties, stator 2 takes off from swivel plate 5a, the resin of the coil 11 of stator 2 is smeared and is finished thus.These load onto swivel plate 5a to the sequence of operations of taking off from stator 2, can be carried out automatically according to control signal by control device 6.
In addition, more than be an example of heating means, resin semar technique.Can also be for example, heated stator 2 moved on to smear the position, will heat and resin spreads upon other position and carries out etc., the smearing without machine of resin is with manually also operating or the like.Can adopt suitable method according to situations such as the heating purposes of coil 11 and purposes, coil 11 self forms.
As mentioned above, heater 1 for above-mentioned example, between the joint 7a of the coil 11 of stator 2 with conductor 8 connect make coil 11 form the closed-loop path states after, feed electric current that higher-order of oscillation machine 4 produces in the heating coil of wire 3 that in the through hole 11a of coil 11, disposes and heater coil 11, the magnetic flux that produces based on the heating coil of wire 3 produces high frequency induction current self (eddy current loss) heating, with in the closed-loop path, produce Joule heats based on induced current and heat by coil 11, can make coil 11 be heated to institute's fixed temperature at short notice effectively.
In addition, the bottom of stator 2 is fastening by the swivel plate 5a of position changeable mechanism 5, the rotation of motor 5b is constantly rotated stator 2, promptly heat the constantly heating changeably of relative position relation of the coil of wire 3 and the inner face of the through hole 11a of coil 11, make the hole 11a inner face of coil 11 evenly produce induced current, the top and the bottom end 11b of coil 11 can evenly heat at its circumferencial direction comprehensively.According to these, the end 11b of the coil 11 of stator 2 is effectively heated, and each coil 11 gap of end winding 11b are with stable resin ground, fix reliably, thereby has obtained the motor of excellent performance.Simultaneously, can heating effectively under stable status for the coil 11 of stator 2.
And, according to experiment, be heated to institute's fixed temperature required time for the 11 end 11b of the coil in the above-mentioned example and carry out record, the voltage suitable with the supply voltage of motor is provided between joint 7a, compare with the method for record in the patent documentation 1, the fact that several times to tens times time is shortened is identified.For example, be applicable to the stator coil of SC coil motor etc., very big practical function is arranged.
In addition, because being peripheries of laminal magnet 3a, the heating coil of wire 3 twines slightly writing board shape of formation with round copper pipe 3b, its one side can easily be set near also omiting equally spaced at horizontal and above-below direction as far as possible with the through hole 11a inner face of coil 11, therefore not only through hole 11a inner face can be heated more equably, simultaneously, the installation of the heating coil of wire 3 self is also easy, and the installation exercise in the through hole 11a of coil 11 etc. also can carry out smoothly.
And higher-order of oscillation machine 4 is to be formed by transistor frequency converter, and the action of this transistor frequency converter is by control device 6, with related controls such as motor 5b, 5d, resin dischargers 14.Therefore, higher-order of oscillation machine 4 self compactness, power saving.Simultaneously, after motor 5b, 5d, the 14 associated actions of resin discharger, heating process and resin are smeared operation can full automation.In addition, the joint 7a of the adapter plate 7 that is provided with in conductor 8 and the shell 9 links to each other, and for example, along with the heater switch ON of control device 6 operates, heating process automatically performs, and has improved the operability that adds hot work.Therefore, obtained the heater 1 of operating characteristics and transaction capabilities excellence.
In addition, the joint 7a of coil 11 connects with conductor 8, for improving the efficiency of heating surface, even also can handle easily under the situation that has a plurality of coils 11, complex coil to construct, and can both be effectively suitable to the coil of various motors, therefore obtain the heater 1 of a highly versatile.In addition, the heating coil of wire 3 is tabulars, and the heating coil of wire 3 self shape simplifies, cheap.Simultaneously, used the transistor frequency converter of power saving to reach operating cost attenuatingization purpose as higher-order of oscillation machine 4.The result has obtained the low stator 2 of cost.
And, about above-mentioned example, although stator 2 by vertically flatly peace (putting) put on swivel plate 5a, the present invention is not limited to this, for example, adopts through hole 11a with coil 11 to be in laterally and the structure of rotation also has good result.In the occasion of laterally rotating, end winding 11b is in position, the left and right sides, and the installation of the heating coil of wire 3 and resin discharge nozzle 13 is carried out easily.In addition, position changeable mechanism 5 grades in the above-mentioned example also just as an example, under the scope that does not break away from the object of the invention, can change as one sees fit.
The present invention is not limited only to other the stator coil of motor such as the stator coil, stepping motor of SC coil motor, and is applicable to the rotor coil of various motors, or the heating of various winding coils beyond the motor etc.Also can be selected for use suitable material by the resin smeared according to the purposes of coil, form etc.
