Description

Winding device and winding process

The present invention relates to a kind of for example Winder of high frequency coil of coiling parts that is used for, particularly relate to and a kind ofly have lead and lead the Winder of mouth and use the method that this Winder winds the line.

Having the common self-action Winder of leading mouth has a limitation, needs the diameter of the line handled must be at least greater than about 50 to 60 microns exactly.But then, currently exist a kind of diameter that tends to the line that to handle more and more thinner, to cooperate carrying out at a high speed and the needs of performance of coiling work.Carrying out recently about the research work of using a kind of meticulous especially line of 20 to 40 microns.

Yet, in situation based on common Winder of leading the mouth system and the method for winding (as following described) of using this device with reference to accompanying drawing, use a kind of extremely meticulous its diameter less than 40 microns line, make it coiled coiling work and be difficult to carry out.

At United States Patent (USP) № 4,157, to narrate a kind of like this coil-winding and line end among the 165A and pricked the knot device, this device has a garden tubular lead that is installed on the lead guiding parts and leads mouth.

This device can make lead lead mouth around the rotation of binding post, makes to lead lead that mouth confesses just in this binding post position from this lead.Be close to a coiling bobbin by making lead lead mouth, the axle that supports this bobbin is rotated, so just be made into a coil on this bobbin.

The present invention above-mentionedly thisly has garden tubular lead and leads the improvement of the Winder of mouth.

The purpose of this invention is to provide a kind of Winder that can be applicable to make the coil of quite little size.

In the accompanying drawings, Fig. 1 to 13 shows the various views of one embodiment of the present of invention, wherein:

A kind of prior art very close with the present invention at first described with reference to Figure 16 and 17, and then describes referring to figs. 1 through 15 pairs of embodiments of the invention.

Figure 16 shows a kind of common Winder, and it comprises a coil component 10 that is blocked by dop 20.Coil component 10 comprises that is furnished with many bases 14 that protrude in the binding post 12 of outside, and a bobbin 16 that is fixed on the base 14.

Lead 40 is being wound up on the bobbin 16 of coil component 10, end portion is being continued to be wound up into again in the step on the binding post 12, generally all using above-mentioned Winder as shown in Figure 16.This general device is furnished with one and leads mouth 30, and leading mouth has a hole 32 that is used for for line, and this shows more in detail in Figure 17.Lead the interior and outer corner angle 36 and 38 of the front end 34 of mouth 30 and make circle or arc, to avoid damaging line 40.Because this mouth 30 of leading allows that lead 40 can be guided at an easy rate and enters a narrow position, for example, the position between two binding posts 12, it is widely used in the automation Winder of being furnished with the miniature coils parts.

Yet, as shown in figure 16, move when the end of attempt fixing cord 40 and with high-speed side and to lead mouth 30, particularly also be accompanied by when motion landing simultaneously, lead is tightened up, its surface is subjected to intense attrition simultaneously, thereby produces deformation, causes the state of a temporary transient tensioning.For this reason, under the situation of using a kind of very thin lead with less tensile strength, when leading mouth 30 when mobile on a large scale, produce lead with regard to regular meeting and curve the problem that the position of acute angle fractures at the front end of leading mouth 30.Therefore, just the superfine lead of diameter less than 40 microns can not be used on this common Winder.

The present invention just is intended to provide a kind of Winder and a kind of method for winding, it can reel satisfactorily superfine lead winding and still can keep and lead the premium properties that mouth imports line at narrow position.

Fig. 1 to 13 shows one embodiment of the present of invention, wherein with Figure 16 and 17 corresponding parts, is marked with identical label respectively in these figure, and additional relevant explanation.

With reference to Fig. 1 and 2, shown coiling is arranged and is comprised an energy by arrow X among Fig. 1, the matrix 1 that the indicated direction of Y and Z moves and a guider nozzle base 50 that is fixed on the matrix 1.Cylinder block 2 and some mouths 30 of leading of a blowing air are housed on guider nozzle base 50.A sleeve 60 that is configured in guider nozzle base 50 opposites is installed in piston 3(Fig. 2 of the cylinder 2 of blowing air) on.Like this, receiver 60 is done moving up and down along with moving of piston 3 with respect to guider nozzle base 50.On receiver 60 with lead that mouth 30 is corresponding to be equipped with some sleeves 70, these are led mouth 30 and insert respectively in the hole of each sleeve 70.Sleeve 70 is moved with receiver 60 by the manipulation of the cylinder 2 of blowing air.When receiver 60 is positioned at upwards the position as shown in Figure 1, lead mouth 30 just protrude in sleeve 70 below, on the contrary, when receiver 60 is positioned at regard to guider nozzle base 50 when being downward position, the front end of sleeve 70 (lower end) just is lower than leads mouth 30.Owing to be fixed on the matrix 1 by leading the lead targeting part that mouth 30 and sleeve 70 formed, thus it can with matrix 1, guider nozzle base 50 and sleeve 60 together, arrow X in Fig. 1, the indicated direction of Y and Z moves.

Do not show among one group of dop 20(Fig. 1) each coil component 10 is stuck between them.In addition, each tension disk 80 that lead 40 is sandwiched in therebetween is positioned in the position that separates with pitch of the laps parts 10.Each tension disk 80 constituted it can integral body be moved up and down, and be furnished with a tubular body 82 and the pressure piece 84 that energy slides as shown in Figure 3 in tubular body 82.Tension disk 80 is to clamp line 40 with the lower surface of the upper surface of tubular body 82 and pressure piece 84.Because pressure piece 84 always is pressed on the tubular body 82 downwards by the spring (not shown), tension disk 80 is always closing usually, have only when pressure piece 84 cylinder (not shown) by a blowing air, or the like when being pulled or pushing open by force, just be opened.

, turned by roller 4 guidings after a spool (end shows the figure) is pulled out at lead 40, pass the hole of leading mouth 30, its end portion is clamped by tension disk 80 as a result.

Fig. 4 is, looks face by the amplification of leading the cover in the lead targeting part 5 that mouth 30 and sleeve 70 formed, and this lead targeting part is chosen from the whole series.Each sleeve 70 has a hole 72, leads mouth 30 and is inserted in this hole, and sleeve is columnar basically, and its fore-end 74 is processed to annular.Sleeve 70 is along with being moved with respect to leading mouth 30 along the direction of leading mouth 30 length by the moving of the receiver that cylinder 2 drove 60 of aforementioned blowing air.As previously mentioned, the amplitude that sleeve 70 moves is exactly the position (here its front end 74 be pulled (lifting) to the front end 34 of leading mouth 30 on) of front end 74 from being pointed out by solid line of sleeve 70, to the position of pointing out by dotted line, the displacement of ((decline) was under the front end 34 of leading mouth 30 before its front end 74 was pushed here).The corner angle 76 of sleeve 70 front ends with 78 with the same arc that is processed into of situation of the corner angle 36 of leading the mouth front end and 38.In addition, through selection, the corner angle 76 and 78 of barrel forward end, its each radius of the radian is bigger than the radius of the radian of the cambered surface of the corner angle 36 of leading mouth and 38.

Though in the above-described embodiments, sleeve 70 is inwardly tapered in its lower end, is not necessarily must form this taper.In addition, though in the above-described embodiments, the corner angle 76 of sleeve 70 front ends and 78 form a semi-circular cross-section by common cambered surface is adjacent, but also can adopt a kind of like this profile, be that its front end 74 is planes, and form independent cambered surface respectively at two corner angle 76 and 78 places, as shown in Figure 5.

Using reel on the coil component method of a winding of above-mentioned Winder will be described below.

As shown in Figure 6, the coil component 10 that winds the line is as yet at first brought to dop 20, so that tension disk 80 of end portion 42 usefulness of line 40 is clamped.At this moment, lead targeting part 5 is in company with showing among the matrix 1(figure) leave dop 20 near tension disk 80.Moreover receiver 60 is in the position of a decline, leads under the mouth 30 so the front end 74 of sleeve 70 just protrudes in.

Next step, the lead targeting part 5 that is in above-mentioned state is shifted to coil component 10, promotes sleeve 70 so that lead the front end 34 of mouth 30 and give prominence to below the front end 74 of sleeve 70, as shown in Figure 7.So lead targeting part 5 is wound on lead 40 root of predetermined binding post 12 around binding post 12 rotations.

After the work that lead 40 is wound up into binding post 12 was finished, tension disk 80 descended at once and is closing, as shown in Figure 8.Lead 40 just is tightened up like this, and therefore, its end portion 42 is just by bending and the tension consumingly of refining binding post 12; So lead 40 is cut off from the root portion that connects binding post 12.The end portion 42 of lead is out of use, and can open binding clasp 80 usefulness air-flows and it be dispelled or with similar method it is taken out.

Then, dop 20 then rotates line 40 on bobbin 16 as shown in Figure 9, at this moment, in order to make the lead 40 can be alignedly on bobbin 16, lead targeting part 5 need be done to the right synchronously with the rotation of dop 20 and moving (as shown in FIG.) of direction left, perhaps lead targeting part 5 is placed an off-line axle 16 to reserve at interval position slightly, so that can direct into naturally on the bobbin 16 from leading the lead 40 that mouth 30 pulls out.

After finishing in the coiling work on the bobbin 16, lead 40 just is moved toward the next door of second binding post, this second binding post be positioned at the binding post that winds lead 40 the back, as shown in Figure 10, at this moment, lead mouth 30 and give prominence to, lead mouth 30 and rotate so that lead 40 is wound on its root around this binding post.

After the coiling work on coil component 10 was finished by this way, sleeve 70 was lowered by for the second time, as shown in Figure 11, the front end 74 of sleeve 70 is projected into lead mouth 30 below, tension disk is opened, make Winder be in stand-by state.

As shown in figure 12, lead targeting part 5 was roughly 180 rotations of spending round the tension disk of opening 80 after, tension disk 80 was just closed.In addition, when tension disk 80 descended, as shown in Figure 13, the end portion 42 of the lead on the junction pole 12 was tightened up, and in aforesaid mode its root from junction pole is cut off.At this moment, because lead targeting part 5 lead 40 is on one side drawn back a segment distance when tension disk 80 descends, so lead 40 just can not have been fractureed.

So the pitch of the laps parts 10 of the work that winds the line are thereon thrown off from dop 20, make it enter next step and new pitch of the laps parts are connected on the dop 20.Like this, Winder is got back to again as the state among Fig. 6.Correspondingly, repeat above-mentioned action, coiling work is gone on continuously.

As mentioned above, according to method for winding of the present invention, when the activity of leading mouth 30 less, for example, the coil of wire on bobbin and binding post the time, is led mouth 30 and just given prominence to outside sleeve 70, but must at full speed do to move on a large scale when leading mouth 30, for example, during mobile between coil component and tension disk, then the front end of sleeve 70 just is projected into and leads outside the mouth 30.

In the above-described embodiment, lead mouth 30 and sleeve 70 and all be processed into arc respectively, and the radius of the radian of sleeve 70 edges and corners cambered surfaces is greater than the radius of the radian of leading mouth 30 edges and corners cambered surfaces in the edges and corners of separately front end.Therefore, when the lead 40 of pulling out from lead pilot unit 5 was bent towards the side direction, as shown in Figure 14, the bent angle of lead 40 relatively relaxed, also become bigger with the contact-making surface of lead pilot unit 5 front ends, thereby the power that affacts on the sweep 44 of lead 40 is that disperse and lax.

Should be noted that the present invention might not be limited to a kind of like this profile, promptly therein the radius of the radian of the corner angle 76 of sleeve 70 and 78 its each cambered surfaces greater than the radius of the radian of the corner angle 36 of leading mouth 30 and 38 its each cambered surfaces.For example, even under the mutually the same situation of each cambered surface radius of the radian of each cambered surface radius of the radian of leading mouth corner angle 36 and 38 and sleeve corner angle 76 and 78, lead mouth 30 if adopt a kind of like this device that sleeve 70 is protruded in a little, as shown in figure 15, the bent angle of line 40 still relatively relaxes, in such structure, lead is led the mouth 30 more not frangibility of reeling than independent use therein.

According to Winder of the present invention and method for winding,, therefore, when guide wire at full speed, just can avoid having strong pulling force and be applied on the line because lead can not curve acute angle at the front end place of lead targeting part.Like this, even when using a kind of extremely thin line, the method for winding of this not frangible lines also just can have been finished.

In addition, relatively to a secondary guider nozzle base and receiver on dispose a large amount of mouth and sleeves of leading respectively, just might carry out the system that the while reels on a large amount of coil components.Another advantage is as follows: because to lead mouth is a kind of meticulous parts, the diameter of its head portion has only 0.8mm, so must be accurately when making.A kind of like this parts should be very expensive and easy deformation, yet, when according to arrangement of the present invention, thisly lead mouth owing to covered by a very thick sleeve, therefore in fact just obtained good protection.
