Then, the action to chip coil manufacturing installation 100 describes.By being installed in the action of the not shown controller control chip coil manufacturing installation 100 on the chip coil manufacturing installation 100.
At first, mainly with reference to Fig. 9, to winding process, and the contraposition operation of lead-in wire (4a, 4b) and electrode 5 describe.Fig. 9 is for representing the figure of winding process and contraposition operation by the seasonal effect in time series order.
As preparation, make core body supporting fixture 21 supporting core bodys 1.Specifically, by driving the cylinder (or hydraulic cylinder) 6 on the core body supporting device 10, piston 27 pushing clamping components 24, thereby the L font portion 23 of opening wide core body supporting fixture 21.Then, after the flange part 3b that does not form electrode 5 in core body 1 is positioned in the L font portion 23, remove the pushing of piston 27.Like this, the compressed part 24a of clamping components 24 presses against flange part 3b in the L font portion 23 by the active force of elastic component 25, core body supporting fixture 21 supporting core bodys 1.
Under the state of core body supporting fixture 21 supporting core bodys 1, reel portion 2 and the flange part 3a that is formed with electrode 5 become the state outstanding from core body supporting fixture 21 ends.
The clamping components 65 that is used in the lead maintaining body 60 of delivery nozzle 6 tops configurations keeps the lead 4 (Fig. 9 (A)) that transfers out from delivery nozzle 6.Lead 4 between clamping components 65 and the delivery nozzle 6 around leading part 4a, and forms the flat portion 7 that specific length is crushed for just.
Begin winding operation from such state to core body 1.
At first, drive 3 travel mechanisms 79, first base station 34 and second base station 64 are moved, make delivery nozzle 6 rotating shaft, to be cylinder element 36 central shafts with the reel portion 2 of core body 1 axial consistent, and makes delivery nozzle 6 move (Fig. 9 (B)) to the periphery of the reel portion 2 of core body 1.
The first of lead 4 moved in the reel portion 2 around leading part 4a, make itself and flange part 3b inwall butt, under this state, drive delivery nozzle turning motor 40.Like this, rotation around the delivery nozzle 6 winding reel portions 2, the lead 4 that transfers out from delivery nozzle 6 is wrapped in (Fig. 9 (C)) in the reel portion 2.
Finish after the coiling of the regulation number of turn, stop winding operation,, flatten the lead 4 of specific length and make it form flat by driving the cam mechanism 47 that lead flattens mechanism 31.Then, after lead 4 moves forward predetermined distance, stop winding operation, flatten once more specific length lead 4, make it form flat.Like this, in lead 4, form 2 flat portions 8,9 of predetermined distance apart.
Carry out winding operation once more, near the initial flat portion 8 that forms of flattening of the configuration flange part 3 that is formed with electrode 5.In addition, mobile delivery nozzle 6 makes flat portion 8 combine with the end face 3d of flange part 3a.When carrying out aforesaid operations, also make to keep first clamping components 65 to move around leading part 4a, make first flat portion 7 also combine (Fig. 9 (D)) with the end face 3d of flange part 3a around leading part 4a.
Making under flat portion 7,8 and the state that the end face 3d of flange part 3a combines, make delivery nozzle 6 and clamping components 65 move stretching lead 4 along direction respectively away from core body 1.Carry out ensuing operation like this, easily, be about to flat portion 7,8 contrapositions (with position alignment electrode 5a, 5b of flat portion 7,8) on electrode 5a, 5b.
Under flat portion 7,8 being combined with the end face 3d of flange part 3a and stretches their state, move up and down platform 80 and move downwards by making, delivery nozzle 6 and clamping components 65 together descend, and make flat portion 7,8 crooked and contraposition (Fig. 9 (E)) on electrode 5a, 5b respectively along flange part 3a.Under the situation of the operation of not carrying out above-mentioned lead 4 is stretched, when delivery nozzle 6 and clamping components 65 descended, lead 4 can be lax, is difficult to accurate contraposition.
Like this, just around flat portion 7 contrapositions of leading part 4a on electrode 5a the position alignment electrode 5a of the flat portion 7 of leading part 4a (just around), another flat portion 8 contrapositions are on electrode 5b.The lead-in wire that is formed with this flat portion 8 is eventually around leading part 4b.
Utilize the go between contraposition of (4a, 4b) and electrode 5 of the flat portion 7,8 of lead-in wire.Compare with round conductor, flat portion 7,8 is stabilized on the flange part 3a with being difficult to depart from.Therefore, can make and go between contraposition exactly on electrode 5.
Make clamping components 65 descend, make in the flat portion 7 crooked also processes of contraposition on electrode 5, the tension force of lead maintaining body 60 relaxes mechanism 62 and 63 actions of tension stability mechanism.With reference to Figure 10 this action is described.Figure 10 (A) is the figure of the action of explanation tension stability mechanism 63 for the figure of the action of explanation tension force mitigation mechanism 62, Figure 10 (B).
Be combined in when stretching on the flange part 3a and to it making just around leading part 4a, clamping components 65 is moved towards the direction away from core body 1, therefore, just the tension force around leading part 4a becomes big.In the situation of this sample, shown in Figure 10 (A), set tension force as follows and relax mechanism 62, piston 72 is contained in the cylinder 71, making clamping components 65 can be the center swing with axle 70.Even discharge the drive medium in the cylinder 71, piston 72 can be free to slide in cylinder 71, clamping components 65 also can be swung.
By setting as above, clamping components 65 moves to the direction away from core body 1, and afterwards, even just becomes in the decline process greatly around the tension force of leading part 4a, clamping components 65 also can be swung and produce at the beginning of the inhibition effect around the tension force of leading part 4a.Therefore, can prevent that just the paratonia change around leading part 4a is big.
Shown in Figure 10 (B), if clamping components 65 descends again, then at the beginning of around the curved face part 75a butt of the ways 75 of leading part 4a and tension stability mechanism 63 and by its guiding.Like this, just when leading part 4a is directed to member 75 guiding, make tension force relax cylinder 71 actions of mechanism 62, the rearward end of clamping clamping components 65 with piston 72 and holding plate 73.Like this, clamping components 65 is fixed and can not swings.
Just be directed under the state of member 75 guiding around leading part 4a, just around the tension variation of leading part 4a the time, absorb mentioned strains by the helical spring between ways 75 and clamping components 65 76 and change.Like this, will just when leading part 4a contraposition is on electrode 5, can stablize first tension force around leading part 4a by the effect of tension stability mechanism 63.
Then, with reference to Figure 11, first flat portion 7 around leading part 4a was described with the operation that engages of electrode 5b around the flat portion 8 of leading part 4b with electrode 5a and end.Figure 11 engages the figure of operation for represent lead according to the seasonal effect in time series order.
Shown in Fig. 9 (E), lead-in wire (4a, 4b) and electrode 5 state of contraposition mutually further descends delivery nozzle 6 and clamping components 65 certainly.At this moment, the pre-configured a pair of clip 28 that is in open state below core body 1 makes two lead-in wires pass the opening portion of clip 28 and descend (Figure 11 (A)).
Shown in Figure 11 (A), descend by making delivery nozzle 6, from delivery nozzle 6, transfer out flat portion 9 in 2 flat portions 8,9 of predetermined distance setting, that be crushed and form afterwards.
Close the clip of opening 28, two lead-in wires of fixing maintenance.The fixing maintenance, fixed the parts (Figure 11 (B)) that keep between the flat portion 8,9 around the clip 28 of leading part 4b side eventually.
Then, remove at the beginning of 66 pairs of the push pedals in the clamping components 65 clamping around leading part 4a.And, clamping components 65 is moved, keep eventually the part (Figure 11 (C)) between the flat portion 9 that the clip 28 at leading part 4b place and flattening afterwards form.
Keeping whole under the state of leading part 4b at clamping components 65, clamping components 65 and delivery nozzle 6 turn back to the primary position of winding process.By this operation, cut off eventually around leading part 4b (Figure 11 (D)).Turn back to lead 4 that the clamping components 65 of primary position kept and become the first of the core body 1 that next winds the line around leading part 4a.That is, the flat portion 9 that is formed by being crushed afterwards in 2 flat portions 8,9 of lead flattening mechanism 31 shapings becomes first flat portion around leading part 4a.
Cut-out after leading part 4b, rotates turntable 13 eventually, makes the core body 1 of having finished winding process and contraposition operation relative with wire-bonded mechanism 12.
Because flat portion 7,8 is crushed, therefore, the insulation tunicle of flat portion 7,8 becomes the state of attenuation.In addition, highly low because flat portion 7,8 is crushed, therefore, can make heating plate 96, and the thermal capacitance of heating plate 96 easily pass to scolding tin near scolding tin.Therefore, heating plate 96 can easily melt the insulation tunicle of flat portion 7,8 and be formed on electrode 5 these both sides of lip-deep scolding tin.Like this, shown in Figure 12 (A), the side surface part of flat portion 7,8 engages by scolding tin 107 with electrode 5.
Then, with reference to Fig. 8 and Figure 13, the action of lead shut-off mechanism 103 is described.Fig. 8 is the figure of the action of expression cutter 104, and Figure 13 is the figure of the action of expression lead push part 105.
As shown in Figure 8, after finishing the joint operation, the cutter 104 that is configured in wire-bonded mechanism 12 bottoms is advanced, around leading part 4a and whole between leading part 4b, make the electrode 5 bottom butts of the lateral surface 3c at this abutting part 104a and flange part 3a place at the beginning of abutting part 104a is passed.Like this, by the 104b of cutter portion to just around leading part 4a with eventually apply otch 106 around leading part 4b.Afterwards, the cutter 104 that has applied otch retreats and turns back to the home position.
Then, as shown in figure 13, the lead push part 105 that is configured in cutter 104 bottoms is advanced, pushing is just around leading part 4a and whole part between otch on the leading part 4b 106 and clip 28.Like this, it is big that the tension force between otch 106 and the clip 28 becomes, and power concentrates on the otch 106, cuts off just around leading part 4a and eventually around leading part 4b from otch 106.
And, as increasing the way of the tension force of part between otch on the leading part 4b 106 and clip 28 just, also can be undertaken by core body 1 and clip 28 are relatively moved around leading part 4a and end.In this case, do not need to be provided with lead push part 105.
In the past, owing to cut off lead-in wire, therefore, also can damage flange part sometimes by lead-in wire being hung over the end of flange part and being stretched.But, according to cutting off the method for lead-in wire, on lead-in wire, apply otch 106 in advance with lead shut-off mechanism 103, power is concentrated on this otch 106, thereby cut off lead-in wire, therefore, when cutting off, do not need big power.Thereby, can prevent the breakage of flange part 3.
As mentioned above, make chip coil by chip coil manufacturing installation 100.Because the lead-in wire of the chip coil that obtains by chip coil manufacturing installation 100 is a flat, therefore, size that can the control chip coil.Thereby, can be simply with the chip coil size Control within required size.
According to above-mentioned the 1st execution mode, can reach effect shown below.
Make lead 4 form flat in advance, the heating of this flat portion is squeezed on the electrode 5, thereby makes wire-bonded on electrode 5, so, there is no need with big power it to be squeezed on the electrode 5 as the situation of round conductor in the past.Therefore, can reduce the possibility of damaging electrode 5 and flange part 3, can obtain to go between and the stable chip coil of the engagement state of electrode 5.
In addition, the flat portion 7,8 by will lead-in wire is combined on the flange part 3, and contraposition with electrode 5 can go between.Compare with round conductor, flat portion 7,8 is difficult to depart from flange part 3 and is very stable.Therefore, can will go between contraposition exactly on electrode 5.
In addition,, therefore, compare, can reduce the scolding tin adhesion amount on the lead-in wire with the situation of round conductor because the lead-in wire that engages with electrode 5 is a flat.Therefore, can keep scolding tin leg portion significantly, thus the connection area when on electrode 5, connecting other electronic units after can guaranteeing.
And, on the lateral surface 3c of the folk prescription flange part 3 on the core body 1, be formed with side by side with first around leading part 4a and eventually around leading part 4b corresponding electrode 5a, 5b.Therefore, can carry out simultaneously just around leading part 4a and eventually around the engaging of leading part 4b and electrode 5, so can make chip coil expeditiously.
The 2nd execution mode
Below, with reference to Figure 14 and Figure 15, the chip coil manufacturing installation 200 of the present invention's the 2nd execution mode is described.Figure 14 is the stereogram of expression chip coil manufacturing installation 200, and Figure 15 is for representing the figure of winding process and contraposition operation according to the seasonal effect in time series order.
Chip coil manufacturing installation 200 is the asynchronism(-nization) of lead 4 being flattened into flat with the difference of the chip coil manufacturing installation 100 of above-mentioned the 1st execution mode.
Below, be that the center is described with the point different with the chip coil manufacturing installation 100 of the 1st execution mode, the member identical with chip coil manufacturing installation 100 adopted identical Reference numeral, omit explanation.
In chip coil manufacturing installation 100, the configuration lead flattens mechanism 31 on the 1st base station 34, before with lead 4 guiding delivery nozzle 6, flattens mechanism 31 by lead this lead 4 is flattened into flat.
In contrast, as shown in figure 14, chip coil manufacturing installation 200 has the lead that replaces lead to flatten mechanism 31 and flattens mechanism 201, and this lead flattens mechanism 201 and is configured on the base 14, and near the core body supporting device 10 relative with winding mechanism 11.
Lead flatten mechanism 201 have with the part of lead 4 flatten into flat pressing mechanism 202, pressing mechanism 202 is directed to guiding mechanism 203 on the lead 4.
At this, will be arranged on preferably that the axially parallel of the guide rail on all bottom surfaces and the reel portion 2 of core body 1 disposes in the supporting member 204, in addition, the compressive plane of the clamping lead 4 of preferred a pair of stripper plate 205a, 205b and the flange part 3a configured in parallel of core body 1.By such arrangement guide rail and stripper plate 205a, 205b, the flat portion of being flattened the lead 4 form by a pair of stripper plate 205a, 205b be formed on flange part 3a on electrode 5 surperficial parallel, therefore, the lead 4 that carries out afterwards becomes easy with engaging of electrode 5.
Horizontal arrangement has a travel mechanism 210 on base 14, disposes another travel mechanism 210 along vertical direction.Two travelling carriages 209 are by link 211 combinations, and supporting member 204 combines with the travelling carriage 209 of another travel mechanism 210.Like this, a pair of stripper plate 205a, the 205b that is supported member 204 supportings can move along level, vertical 2 directions.
In addition, being configured in the ball-screw 208 of a travel mechanism 210 on the base 14, is to be configured in the mode that the edge and the direction of the reel portion 2 axial quadratures of core body 1 are extended.
Below, with reference to Figure 15, winding process that is undertaken by chip coil manufacturing installation 200 and the contraposition operation that goes between 4a, 4b and electrode 5 are described.
Preparation and above-mentioned the 1st execution mode during to core body 1 coiling are roughly the same, and shown in Figure 15 (A), its difference is when beginning to wind the line, just not form flat portion around leading part 4a.
At first, drive 3 travel mechanisms 79, the rotating shaft that makes delivery nozzle 6 is axial consistent with the reel portion 2 of core body 1, and makes delivery nozzle 6 move (Figure 15 (B)) to the periphery of reel portion 2.
Then, by driving delivery nozzle turning motor 40, in reel portion 2, twine a few leads 4.Under this state, drive guiding mechanism 203, pressing mechanism 202 is moved, make pressing mechanism 202 location, make just around leading part 4a between a pair of stripper plate 205a, 205b.Then, shown in Figure 15 (C), by drive member a pair of stripper plate 205a, 205b are moved towards mutual close direction, extruding is just around leading part 4a.Like this, on leading part 4a, form flat portion 7 just.Just on leading part 4a, after the shaping flat shape portion 7, pressing mechanism 202 is retreated.
Then, drive delivery nozzle turning motor 40, the action that winds the line is once more twined in reel portion 2 after the regulation number of turn, stops winding operation.
Then, shown in Figure 15 (D), delivery nozzle 6 is moved to the top of electrode 5b.The lead from delivery nozzle 6 to reel portion 24 under this state is eventually around leading part 4b.And, drive guiding mechanism 203 once more, also on leading part 4b, forming flat portion 8 eventually by pressing mechanism 202.On leading part 4b, after the shaping flat shape portion 8, pressing mechanism 202 is retreated eventually.
Then, shown in Figure 15 (E), make keeping first clamping components 65 and delivery nozzle 6 both sides to move, will just be combined on the end face 3d of flange part 3a around the flat portion 8 of leading part 4b around flat portion 7 and the end of leading part 4a around leading part 4a.
Afterwards, shown in Figure 15 (F), move up and down platform 80 and move downwards by making, thereby delivery nozzle 6 and clamping components 65 are together descended,, make this flat portion 7,8 distinguish contrapositions on electrode 5a, 5b along flange part 3a bending flat shape portion 7,8.Like this, with just around flat portion 7 contrapositions of leading part 4a on electrode 5a, with eventually around flat portion 8 contrapositions of leading part 4b on electrode 5b.
Owing to ensuing operation, be flat portion 7 and electrode 5a, and flat portion 8 is identical with above-mentioned the 1st execution mode with the joint operation of electrode 5b, so omission explanation.
As mentioned above, though just around a few leads 4 are twined in shaping flat shape portion 7 on the leading part 4a in reel portion 2 after, carrying out, certainly also can with eventually on leading part 4b shaping flat shape portion 8 carry out identical time.That is, also can in reel portion 2, twine after the regulation number of turn finishes, just around leading part 4a and progressive forming flat portion 7,8 on leading part 4b eventually.
As mentioned above, in chip coil manufacturing installation 200, around leading part 4a and eventually around the last shaping flat shape portion the 7, the 8th of leading part 4b, soon before contraposition flat portion 7,8 on electrode 5a, the 5b, near electrode 5a, 5b, carry out at the beginning of making.That is, inciting somebody to action just around leading part 4a and whole after leading part 4b guiding electrode 5a, 5b, shaping flat shape portion 7,8.
According to above-mentioned the 2nd execution mode, reach effect as follows.
Because the chip coil by manufacturing installation of the present invention and manufacture method manufacturing mainly is used in miniaturized electronics, therefore, uses minimum core body 1 and superfine lead 4 sometimes.Under situation as described above, before twining lead 4 (before lead 4 guiding electrodes 5) in advance pinch lead wire 4 a part and form in the method for flat portion 7,8, sometimes can be in winding process at flat portion 7,8 places of lead 4 broken string.In addition, because the electrode 5 that is formed on the core body 1 is also minimum, therefore, the flat portion 7,8 that also is difficult to will be shaped in advance exactly is positioned on the electrode 5.
But chip coil manufacturing installation 200 just is directed to electrode 5a, 5b postforming flat portion 7,8 around leading part 4a and end around leading part 4b the general, does not carry out the winding of lead 4 after shaping flat shape portion 7,8.
Therefore, owing to can not twine flat portion 7,8, thereby, can in addition,, flat portion 7,8 can be positioned on electrode 5a, the 5b exactly at flat portion 7,8 places broken string even electrode 5 is minimum yet.
Can recognize, the invention is not restricted to above-mentioned execution mode, can in its technological thought scope, carry out various changes.
