Abstract
To enhance the mass production efficiency of an aluminum electrolytic capacitor, by quickening the molding, especially the temporary bend which requires the longest processing time, and enabling the intermittent sending of a rotating table. A lead terminal 10b is bent temporarily, immediately after being passed in an insertion hole 12a by a temporarily bending die 122 shifting, being accompanied with an insulating seat plate 12. Therefore, the action only for mounting the insulating seat plate 12 to the lead terminal 10b becomes unnecessary. Moreover, since the tips of the lead terminal 10b are bent temporarily, immediately after passing the lead terminal 10b into the passage hole 12a, very small stroke of the temporarily bending die 122 will suffice, and the temporarily bending can be performed quickly.
Description
Technical field
The present invention relates to, the insulation seat board is loaded on lead terminal, the manufacturing process of lead terminal along the almost flatly crooked aluminium electrolytic capacitor up to its root of the lower surface of insulation seat board, lead terminal is expanded into the temporary bending mould of splayed (truncated cone), the almost flatly crooked formal bending die of lead terminal up to its root, correct the temporary bending lead guider of the distortion of lead terminal, and with the manufacture method of the aluminium electrolytic capacitor of machine for automatic working.
Background technology
The installationization that adapts to electronic component, to the automatic mounting technique of printed board, electronic component is made into to have lead terminal, head lower surface (main body lower surface) bending of lead terminal along electronic component, the bonding wire terminal is fixed in printed board to electronic component.
By the part feeding machine, rotary table (machine table), the machine for automatic working of the electronic component that the dress tape cell combines is known, in this machine for automatic working, for example as the special fair 7-44353 communique of Japan Patent, specially permit the such of No. 2878599 communique record, electronic component is supplied to rotary table from the part feeding machine, machining to regulations such as the lead terminal of electronic component form, electronic component is accommodated in the recess of carrier band (plastics embossed tape) with the dress tape cell, seal carrier band with wearing, automatically carry out the supply of electronic component, machining, packing a series of processing such as (encapsulation).
If the minute of angle of rotary table is taken as for example 22.5 °, then obtain 16 indexing positions (station), utilize the some of 16 indexing positions, set the station of machining lettering inspection dress band.Be located on the rotary table on 22.5 ° of ground at interval with corresponding 16 supporting mechanisms of indexing position, the electronic component of being supplied with from the part feeding machine is held in supporting mechanism, under the state that is held, deliver to the station of machining lettering inspection dress band, carry out machining etc.
That is to say, rotary table is sent to each 22.5 ° of intermittences, between turning around, the machining of stipulating on processing stations is performed in the electronic component of supporting mechanism, on the lettering station, electronic component carried out simultaneously letterings such as piece number, lot number, in the performance checking of checking station, reject substandard products, on dress band station electronic component is accommodated in carrier band and seals carrier band and a series of processing on rotary table finish with wearing, the state that is incorporated in carrier band with electronic component is delivered to next process as finished product from rotary table.
As electronic component with the machine for automatic working manufacturing that part feeding machine, rotary table (machine table), dress tape cell are combined, aluminium electrolytic capacitor is arranged, in aluminium electrolytic capacitor,, guarantee insulation so on the head lower surface (main body lower surface) of aluminium electrolytic capacitor, load onto the seat board of making by insulating material (insulation seat board) because use conductive material in its exterior component.Moreover as aluminium electrolytic capacitor, it also is known replacing electrolyte (liquid) and enclosing organic semiconductor (solid) person.
Usually, aluminium electrolytic capacitor is made via following operation in the rotary table (machine table) of machine for automatic working.
1. aluminium electrolytic capacitor 10 is made the shape (Fig. 8 A) of two lead terminal 10b that have its head (main body) 10a and stretch out from the lower surface of its head, and unnecessary lead terminal at first is cut off (Fig. 8 B).This operation is called " pre-cutting ".
2. for the ease of soldering and reduction setting height(from bottom), the root 10b ' of compacting lead terminal makes it planarization (Fig. 8 C).This operation is called " compacting ".
3. on insulation seat board 12, form the through hole 12a that lead terminal 10b inserted, make lead terminal 10b insert through hole 12a and almost bending (Fig. 8 D, Fig. 8 E) flatly.Here, almost flatly before the bending lead terminal 10b, for the seat board 12 that prevents to insulate comes off, lead terminal 10b is expanded (bending) and is become splayed (truncated cone).The operation that lead terminal 10b is bent to splayed (truncated cone) calls " the 1st shaping (being shaped 1) ", and almost flatly crooked operation is called " the 2nd shaping (being shaped 2) ", and this twice bending operation is referred to as " forming process ".Moreover the former is also referred to as " temporary bending ", and the latter is also referred to as " formal crooked ".The accommodating groove of taking in lead terminal 10b is located on the lower surface of insulation seat board 12, by crooked lead terminal is accommodated in accommodating groove, prevents that lower surface is outstanding from the head downwards.
4. cut off unnecessary lead terminal 10b (Fig. 8 F).This operation is called " cutting off lead-in wire ".
5. on the upper surface of head 10a, press (Fig. 8 G) such as seal piece numbers.
6. make mensuration 14 be contacted with lead terminal 10b and check electrical characteristic (Fig. 8 H).
7. the rejecting substandard products are accommodated in the aluminium electrolytic capacitor 10 of qualified product the recess of carrier band (plastics embossed tape) 16 and seal carrier band (Fig. 8 I) with wearing 17.
As mentioned above, on each station of rotary table, implement machining lettering inspection dress band and wait processing, between rotary table turns around, manufactured, the packing of electronic component.Here, rotary table is intermittently sent to, this intermittently send to can not be slower than the processing time in the middle of the machining lettering inspection dress band operation faster, if accelerate intermittently to send to, the time of then turning around shortens and batch process in the unit interval becomes possibility.Usually,,, shorten the processing time in each operation and make send high speed to the intermittence of rotary table, seek to produce in batches the improvement of efficient (manufacturing efficient) so machining is divided into several operations because machining needs the maximum time.
And, in the middle of machining, need the maximum time, so shaping is divided into temporary bending (the 1st is shaped) and formal crooked (the 2nd is shaped) because be shaped.That is to say, the machining in the manufacturing of aluminium electrolytic capacitor is divided into following 5 procedures, on the station of rotary table, carry out these operations respectively.
1. the cut-out of unnecessary lead terminal (pre-cutting)
2. the compacting of lead terminal (compacting)
3. the bending of the splayed of lead terminal (truncated cone) (the 1st shaping=temporary bending)
4. the bending of the almost level of lead terminal (the 2nd is shaped=formal bending)
5. the cut-out of unnecessary lead terminal (cutting off lead-in wire)
In order to shorten the processing time in the machining, in the middle of 5 procedures of being cut apart, temporary bending to be because being necessary to supply with from the outside loads onto the insulation seat board, thus in the middle of 5 procedures of machining, need maximum time, and be with the time that needs separately also long than lettering inspection dress.That is to say, though shaping be divided into temporary bending, reduction in processing time is sought in formal bending, temporary bending still needs the maximum time, the obstacle of the maximum of producing in batches is the temporary bending in being shaped, if shorten the temporary bending time, then sending to the intermittence of rotary table can high speed, produces efficient in batches and improves.
For example, open in the flat 7-235460 communique the following temporary bending that carries out aluminium electrolytic capacitor the spy.
1. aluminium electrolytic capacitor 10 utilizes belt clamp to be held in rotary table (chip manufacture platform), insulation seat board (insulating end daughter board) 12 is adsorbed and is held on adsorption head 20, along with the rotation of rotary table, aluminium electrolytic capacitor 10 is moved to the 1st forming station (temporary bending station) of adsorption head top, and (Fig. 9 a).Here, lead terminal 10b be aligned the insulation seat board (insulating end daughter board) through hole 12a be self-evident.
2. lead terminal 10b inserted the through hole 12a of insulation seat board, and adsorption head 20 insulation of clamping on one side seat boards 12 rise on one side, are contacted with the lower surface (Fig. 9 b, Fig. 9 c) of the head 10a of aluminium electrolytic capacitor up to insulation seat board 12.
3. temporary bending mould 22 risings of below aluminium electrolytic capacitor 10, waiting for (Fig. 9 c).The front end of temporary bending mould 22 is made herringbone, and the herringbone front end of temporary bending mould is lead terminal 10b expansion, and crooked (temporary bending) becomes splayed (truncated cone) (Fig. 9 d).
4. remove the clamping of insulation seat board 12, adsorption head 20 descends, also decline (Fig. 9 e) of temporary bending mould 22 simultaneously.Then, along with the rotation of rotary table, aluminium electrolytic capacitor 10 moves on to the next the 2nd station that is shaped (formal bending position) from the 1st station (temporary bending position) that is shaped.
After the temporary bending that is undertaken by the temporary bending mould, on the station that the 2nd of rotary table is shaped lead terminal 10b up to its root bending to almost becoming level, cut off on the station that cuts off lead-in wire and remove unnecessary lead terminal, the machining of aluminium electrolytic capacitor finishes thus.
About the object lesson of the formal bending on the 2nd station that is shaped, the spy opens in the flat 7-235460 communique and does not address.But, along with send to the intermittence of rotary table, aluminium electrolytic capacitor 10 1 arrives the 2nd station that is shaped, the just rising (Figure 10 f) of formal bending die 52 that front end is smooth, lead terminal 10b up to its root bending to almost becoming level (Figure 10 g), descend and wait (Figure 10 h), this is self-evident.
Here, in above-mentioned spy opens temporary bending method in the flat 7-235460 communique,
1. 20 insulation of adsorption head seat board 12 is transplanted on the root of lead terminal 10b, and the stroke of adsorption head 20 is longer.
2. for the root of temporary bending lead terminal 10b, temporary bending mould 22 also rises to the root of lead terminal, and the stroke of temporary bending mould is longer.
3. the upward stroke of adsorption head 20, temporary bending mould 22 is not simultaneously, but carries out respectively.
So, in this known temporary bending method, because not only the stroke of adsorption head 20, temporary bending mould 22 is longer, and its upward stroke carries out respectively, so be difficult to carry out rapidly temporary bending, temporary bending has become the obstacle of the machine for automatic working medium quantity batch processing of having adorned rotary table.
In addition, if carry out formal bending, then can become almost level (Figure 10 f, g, h) to lead terminal 10b up to its root bending reliably with the smooth formal bending die 52 of front end., the pushing force of formal bending die 52 is delivered to lead terminal via the contact point of lead terminal 10b, formal bending die, acts on lead terminal as tensile force.And tensile force is concentrated the root that acts on lead terminal, and lead terminal is pulled from root, and the head lower surface of aluminium electrolytic capacitor is damaged, and causes aluminium electrolytic capacitor and produces substandard products.In addition, if accelerate the rate of climb of formal bending die 52, then,, be difficult to shorten the processing time of formal bending so be difficult to accelerate the rate of climb of formal bending die because tensile force acts on the root of lead terminal sharp.
Summary of the invention
The object of the present invention is to provide a kind of by carrying out the shaping of lead terminal rapidly, temporary bending is particularly sent high speed to and improve the manufacturing process, temporary bending mould, temporary bending lead guider, formal bending die of the aluminium electrolytic capacitor of producing efficient (manufacturing efficient) in batches and with the manufacture method of the aluminium electrolytic capacitor of machine for automatic working the intermittence that makes rotary table.
If use manufacturing process of the present invention, then the temporary bending mould carries out temporary bending thus immediately along with the insulation seat board moves after making lead terminal insert through hole.
In this constituted, the temporary bending mould was along with the insulation seat board moves, and only being used for thus becomes pack into the action of lead terminal of insulation seat board unwanted.That is to say there is not the suitable thing of the adsorption head stroke in the known formation, only the stroke of temporary bending mould is just passable.And, because after making lead terminal insert through hole temporary bending lead terminal front end immediately, so the stroke of temporary bending mould is very little just enough.So, because just can temporary bending by the very little stroke of temporary bending mould, so temporary bending can promptly carry out, sending to the intermittence of rotary table can high speed, the batch process efficient (manufacturing efficient) of raising aluminium electrolytic capacitor.
In addition, if not at one stroke lead terminal being expanded into truncated cone (splayed) up to its root, and temporary bending is divided into two procedures, then the needed time of temporary bending is by segmentation, the needed time decreased of each temporary bending.That is to say, if temporary bending only is divided into the 1st temporary bending that the lead terminal front end is expanded into the degree that splayed (truncated cone) comes off to the seat board that prevents to insulate, with the position that the insulation seat board is directed to the obstacle that does not become temporary bending on one side, with the temporary bending mould lead terminal is expanded into the 2nd temporary bending of splayed (truncated cone) on one side up to its root, on different stations, carry out the 1st, the 2nd temporary bending, then the needed time of temporary bending is by segmentation, temporary bending is shortened, and sending to the intermittence of rotary table can high speed.
And then, if make rotation roller freely be pushed on lead terminal, carry out formal bending by the idle running of roller, then because be inhibited from of the transmission of formal bending die to the pushing force of lead terminal, the tensile force that produces on lead terminal is very little, so formal bending can be carried out rapidly.

The form that carries out an invention
Be elaborated with regard to embodiments of the invention with reference to the accompanying drawings.
As shown in fig. 1, the machine for automatic working 30 that manufacturing process of the present invention is used has the part feeding machine 32 and the rotary table 34 of aluminium electrolytic capacitor 10, transfers road 36 and extends between part feeding machine and rotary table.
Rotary table 34 is known, for example, form 16 calibration stations by 22.5 ° minute of angle, in an embodiment, wherein 8 calibration station A～H are utilized, aluminium electrolytic capacitor 10 supplies to rotary table 34 via transferring road 36 on station A, aluminium electrolytic capacitor is implemented the machining of regulation on station B～G, and aluminium electrolytic capacitor is taken out from rotary table on station H.
As mentioned above, in the manufacturing of aluminium electrolytic capacitor,, be divided into 5 procedures as the operation of machining:
1. the cut-out of unnecessary lead terminal (pre-cutting)
2. the compacting of lead terminal (compacting)
3. the bending of the splayed of lead terminal (truncated cone) (the 1st shaping=temporary bending)
4. the bending of the almost level of lead terminal (the 2nd is shaped=formal bending)
5. the cut-out of unnecessary lead terminal (cutting off lead-in wire)
For example, on station A, supply to the aluminium electrolytic capacitor 10 of rotary table 34, on station B, cut off unnecessary lead terminal (pre-cutting), on station C, suppress lead terminal (compacting).Load onto the insulation seat board because be necessary from the outside supply, so temporary bending needs more time than other operations of machining, longer than the needed separately time of lettering inspection dress band, temporary bending needs the maximum time, sends to the intermittence of rotary table by about temporary bending time institute.Therefore, in an embodiment, temporary bending is segmented into two procedures, temporary bending lead terminal on station D, E, bending lead terminal flatly on station F.Then, on station G, cut off unnecessary lead terminal (cutting off lead-in wire).
In an embodiment, because the operation of the machining of aluminium electrolytic capacitor 10 is a lot, so on rotary table 34, only carry out machining, the aluminium electrolytic capacitor 10 that on station H machining is finished takes out from rotary table 34, lettering station I, inspection station J, dress band station K are separated from rotary table 34, carry out lettering, inspection, dress band in the outside of rotary table., can be not yet lettering station I, check that station J, dress band station K separate and are located on the rotary table from rotary table 34.
The invention is characterized in the shaping on station D, E, F, temporary bending (the 1st is shaped) and formal crooked (the 2nd shaping) just, because the machining on other stations etc. is known, so the details of be shaped (temporary bending, formal crooked) is described.
Driving at intermittence along with rotary table 34, the supporting mechanism of rotary table arrives station D, the aluminium electrolytic capacitor 10 1 that is held on supporting member is sent to the position of temporary bending, insulation seat board 12 just be admitted to make its through hole 12a aim at the position of lead terminal 10b of aluminium electrolytic capacitor (Fig. 2 a).Certainly, also can before be sent to the position of temporary bending, aluminium electrolytic capacitor 10 insulation seat board 12 be supplied to the position of regulation, and pay no attention to the front and back of the supply order of aluminium electrolytic capacitor 10, insulation seat board 12.On station D, supply is loaded onto insulation seat board 12 and only the front end of lead terminal 10b is expanded into splayed (truncated cone) so that the insulation seat board does not come off, and on next station E lead terminal 10b is almost flatly bent to root.
In an embodiment, insulation seat board 12 is supplied with (Fig. 1) from parts library 37 via supplying with platform 38.Temporary bending mould 122 that can lifting is configured in the below of the station D of rotary table 34, and the insulation seat board is supplied with and is taken as the component delivery rotary table with platform 38, between aluminium electrolytic capacitor 10, temporary bending mould 122.
On station D, aluminium electrolytic capacitor 10, insulation seat board 12 1 are sent to the position of regulation, temporary bending mould 122 just rise (Fig. 2 a), be contacted with immediately after the rising top insulation seat board 12 and on push away it, make the insulation seat board place its front end, the temporary bending mould continues rise (Fig. 2 b).
As shown in Fig. 3 A, for example, temporary bending mould 122 has to be made lambdoid mould main body 122a to front end and clips the configuration of mould main body, makes its front end for example smooth so that a pair of member 122b of the seat board 12 that can keep insulating and constituting.
After lead terminal 10b inserted the through hole 12a of insulation seat board, the mould main body 122a of temporary bending mould was contacted with lead terminal 10b immediately the lead terminal front end is expanded into splayed (truncated cone), carries out temporary bending (Fig. 2 c, Fig. 2 d).
After this, temporary bending mould 122 descends and turns back to home position (Fig. 2 e).Then, rotary table 34 1 is intermittently sent to, and next aluminium electrolytic capacitor 10 just is moved to station D, and next insulation seat board 12 is moved to the position of the regulation of aiming at station D with platform 38 rotations in the seat board that insulate simultaneously supply, occurs the state of Fig. 2 a once more.In addition, the aluminium electrolytic capacitor behind the temporary bending 10 is sent to next station E along with sending to the intermittence of rotary table 34.
So, because insulation seat board 12 is between aluminium electrolytic capacitor 10 and temporary bending mould 122, so the temporary bending mould makes the rising outwardly placed on it of insulation seat board.And, inserted the through hole 12a of insulation seat board at lead terminal 10b after, the temporary bending mould 122 that is positioned at behind the insulating base backboard expands into splayed (truncated cone) to the lead terminal that stretches out from insulation seat board 12 immediately, carries out temporary bending.
Here, temporary bending mould 122 does not need the action that the insulation seat board is risen along with insulation seat board 12 rises.In addition, because after insulation seat board 12 was loaded on lead terminal 10b, temporary bending mould 122 made the bending of lead terminal front end immediately, so the stroke of temporary bending mould is very little just passable.
So, because the needed action of temporary bending only is the lifting of temporary bending mould 122, this action itself also is that very little stroke is just enough, so temporary bending can promptly carry out, can make and intermittently of rotary table 34 send high speed to.
Moreover if lead terminal 10b has been out of shape, then lead terminal can not be aimed at the through hole 12a of insulation seat board, can't insert.Therefore, be located at the temporary bending lead guider 40 of the distortion of correcting lead terminal 10b between rotary table 34 and the insulation seat board supply usefulness platform 38 just passable.
For example, temporary bending lead guider 40 has the male element 42 with prominent shape sheet 42a and has the female element 44 of the translot 44a that prominent shape sheet inserts and constitute as shown in Fig. 3 B, forms W shape groove 42b on the prominent shape sheet of male element.Here, the W shape groove 42b interval P that forms two front end equals the interval of lead terminal 10b (Fig. 2).
Temporary bending lead guider 40 is in aluminium electrolytic capacitor 10 action immediately arriving station D.For example, if being slided from the both sides along continuous straight runs, male element 42, female element 44 clamp lead terminal 10b in the central, then because even for example lead terminal has been out of shape, lead terminal is also led by W shape groove 42, is located in the front end of W shape groove so the distortion of lead terminal is automatically corrected at leisure by the inclined-plane of groove.Certainly, the front position of W shape groove 42 is taken as the position of aiming at the through hole 12a of the seat board that insulate, and lead terminal 10b is aligned through holes automatically.Thereby, by utilizing temporary bending lead guider 40, even lead terminal 10b has been out of shape, also can before temporary bending, correct the distortion and be positioned aligned position, temporary bending can carry out without barrier.
Temporary bending lead guider 40 is not only corrected the distortion of lead terminal 10b, and clamping lead terminal and the distortion (vertical curved) of lead terminal axis direction when preventing temporary bending securely between male element 42, female element 44.Thereby, preferably temporary bending lead guider 40 being located at insulation seat board 12, the seat board that just insulate is supplied with near the platform 38.
Be not limited to and make male element 42, female element 44 formation of clamping lead terminal 10b in the central of sliding from both sides, also can be taken as female element is fixed, make male element movable, the slip by male element lead terminal shift onto clamping on the female element formation.
On station E, another temporary bending mould 124 is being waited for.From Fig. 4, Fig. 5 as can be seen, temporary bending mould 124 for example has makes lambdoid mould main body 124a to the central portion of front end, clips a pair of member 124b of mould main body configuration, and the guider 124c of the seat board 12 that can keep insulating and constituting.Here, ways 124c makes and can integrally rise with mould main body 124a, keep insulation seat board 12 and be directed to the position of the obstacle that does not become the temporary bending that the mould main body carries out, finally the insulation seat board is directed to lead terminal 10b root, in an embodiment, form the L font that covers mould main body 124a.
Moreover, though consider with the interchangeability of temporary bending mould 122 and on temporary bending mould 124, also use a pair of member 124b,, then can omit a pair of member 124b if thickening forms mould main body 124a.Mould main body 124a is the whole herringbone of making of front end, but only its central portion made herringbone, and even shape is made at both ends.
If describe the temporary bending that is undertaken by the temporary bending mould on station E 124, aluminium electrolytic capacitor 10 1 is sent to station E, and temporary bending mould 124 just rises (Fig. 4 f), and the ways 124c that rises with mould main body 124a at first keeps the seat board 12 that insulate.Insulation seat board 12 remains on the ways 124c, one is directed to the position of the obstacle of the temporary bending that does not become the lead terminal 10b that mould main body 124a carries out, and mould main body 124a just is contacted with lead terminal 10b and expands into splayed (truncated cone) (Fig. 4 g).
Here, lead terminal 10b was contacted with herringbone portion of mould main body 124a central authorities and is expanded before the par that is contacted with mould main body 124a two ends.Certainly, because keeping out of the way insulation seat board 12 guiding, ways 124c do not become the position that mould main body 124a carries out crooked obstacle, so the formal bending that the insulation seat board might as well hinder the mould main body to be carried out.So because at first with central herringbone portion lead terminal 10b expansion, and on the inclined-plane of central herringbone portion guiding and be contacted with the par at two ends, so avoided rapid bending, the bending successfully of lead terminal quilt at the place, par at two ends.Thereby temporary bending mould 124 can rise at a high speed.And then the central herringbone portion of mould main body 124a, the par at two ends just can expand into splayed (truncated cone) to lead terminal 10b up to its root with very little stroke.
Moreover, as shown in the figure, herringbone is made by central authorities if use, the mould main body 124a of par is made at two ends, then become possibility by the temporary bending that temporary bending mould 124 carries out with little stroke.But, can the par be set yet and mould main body 124a is made herringbone, in this occasion, though stroke strengthens, lead terminal is by successfully crooked continuously.In addition, if continuous inclined-plane is not made on lambdoid inclined-plane, and below reduce the inclination angle and make mild inclined-plane, then can not only guarantee continuous bending but also reduce stroke.
So, temporary bending mould 124 is risen at a high speed, and come bending lead terminal 10b with the very little stroke of temporary bending mould, temporary bending also can promptly carry out on station E.Certainly, the needed time of temporary bending on the station E is no more than the needed time of temporary bending of station D.
As can be seen from Figure 5, because form the groove 125 that lead terminal 10b inserted in the central authorities of ways 124c, so ways does not become the obstacle of the temporary bending of lead terminal 10b, lead terminal bends to its root by temporary bending mould 124.Ways 124c is directed to insulation seat board 12 position of the head bottom surface that is contacted with aluminium electrolytic capacitor 10, mould main body 124a one expands into splayed (truncated cone) to lead terminal 10b up to its root, carry out temporary bending, temporary bending mould 124 just descends and returns the home position and wait for (Fig. 4 h).Moreover, as groove 125, also can substitute illustrated elongated slot two slotted eyes that lead terminal was inserted are set.
Aluminium electrolytic capacitor 10 is sent to next station F, carries out formal bending.Formal bending die 152 is being waited for (Fig. 6 i) on station F.As can be seen from Figure 7, form groove 152a on the upper surface of formal bending die 152, two rotation roller 152b freely are accommodated in the groove.On freely roller 152b of rotation was located at and outwards staggers the position of several mm from the root of lead terminal 10b, formal bending die 152 1 rose, and roller just is contacted with lead terminal 10b.Here because roller 152b rotates freely, so while once be contacted with lead terminal 10b dally (rotation) push lead terminal and bending.
In the formal bending of being undertaken by formal bending die 152 with roller 152b, because roller pushes lead terminal 10b while dallying, so be inhibited from the transmission of formal bending die to the pushing force of lead terminal, the tensile force that produces on lead terminal is minimum.Therefore, can prevent that lead terminal 10b from being pulled at its root, the head lower surface of aluminium electrolytic capacitor 10 damages, or the facial mask of lead terminal 10b is peeled off.Therefore, formal bending die 152 can rise at a high speed, and formal bending can promptly be carried out.
Because the groove of taking in lead terminal 10b forms on the lower surface of insulation seat board 12, thus formal bending die 152 rise to contact insulation seat board lower surface almost the position and lead terminal 10b almost bending flatly up to its root.Because in temporary bending, lead terminal 10b is expanded, so can be successfully almost flatly crooked up to its root in formal bending lead terminal from its root.And, lead terminal 10b is incorporated in the accommodating groove of insulation seat board 12 lower surfaces, with insulation seat board lower surface same surface on along continuous straight runs extend (Fig. 6 j), one almost flatly bends to root to lead terminal, formally bending die 152 just drops to home position (Fig. 6 k).
So temporary bending is divided into and loads onto insulation seat board 12, for coming off, the seat board that prevents to insulate the front end of lead terminal 10b is expanded into the 1st temporary bending of splayed (truncated cone), with the position that the insulation seat board is directed to the obstacle that does not become temporary bending on one side, lead terminal is expanded into 2nd temporary bending of splayed (truncated cone) to root on one side, thus the needed time slice of temporary bending.Here, though the needed needed time of time ratio the 2nd temporary bending of the 1st temporary bending will be grown, but because necessary operation only is the lifting of temporary bending mould 122 in the 1st temporary bending, this action itself also is that very little stroke is just enough, so the 1st temporary bending can promptly carry out.In addition, by using rotation roller 152b freely, formal bending can promptly be carried out, and the formal crooked needed time is no more than the needed time of the 1st temporary bending.
By the curring time of sending to the intermittence of left rotation and right rotation workbench 34, say rapidization of temporary bending exactly, send high speed the intermittence of rotary table to becomes possibility, and the batch process efficient of aluminium electrolytic capacitor 10 (manufacturing efficient) improves.And then if temporary bending is divided into two, then the temporary bending time is shortened by segmentation, sends further high speed the intermittence of rotary table to, and the batch process efficient of aluminium electrolytic capacitor 10 (manufacturing efficient) further improves.For example, if on machine for automatic working 30, adopt the manufacturing process of the present invention that temporary bending is divided into two, then can by 200/assign to make aluminium electrolytic capacitor 10, compare with the prior art machine and produce about 1.7 times of improved efficiency in batches.
The foregoing description is to be used for illustrating of the present invention, limits of the present inventionly anything but, implements distortion, transformation etc. and all comprise in the present invention in technical scope of the present invention, and this is self-evident.For example, though in an embodiment aluminium electrolytic capacitor 10, insulation seat board 12, temporary bending mould 122,124, formal bending die 152 disposes along the vertical direction, make temporary bending mould, formal bending die lifting, but also can dispose by along continuous straight runs, make temporary bending mould, formal bending die along continuous straight runs reciprocating motion.
The effect of invention
As mentioned above, in the present invention, the temporary bending mould makes thus along with the insulation seat board moves Lead terminal carried out temporary bending after inserting through hole immediately. Therefore, only be used for the insulation seat board is loaded on The action of lead terminal becomes unwanted, only depends on the stroke of temporary bending mould just can carry out temporarily curved Bent. And, because after making lead terminal insert through hole temporary bending lead terminal front end immediately, So the stroke of this temporary bending mould is minimum just enough. Therefore, temporary bending promptly carries out, The batch production efficient of aluminium electrolutic capacitor improves.
If a pair of member with the shape of the seat board that can keep insulating clips lambdoid mould main body Consist of the temporary bending mould, then the front end with a pair of member can keep the seat board that insulate reliably.
If have the prominent shape of W shape groove that band is taken as the interval of the front end of groove at the interval of lead terminal The female element that the male element of sheet and prominent shape sheet insert and consist of the temporary bending lead guider is facing The time crooked aluminium electrolutic capacitor lead terminal the time with the inside of W shape groove lead terminal is clamped in sun Between member, the female element, though then for example lead terminal be out of shape, the distortion also automatically corrected, Can be positioned exactly aligned position with the through hole of the seat board that insulate to lead terminal. In addition, because of For lead terminal is held between male element, the female element securely, so can prevent temporary bending The time the distortion (vertical curved) of lead terminal axis direction.
And then, load onto the insulation seat board if temporary bending is divided into, and in order to prevent the seat board that insulate Coming off expands into the front end of lead terminal 10b the 1st temporary bending of splayed (truncated cone), With the position that the insulation seat board is directed to the obstacle that does not become temporary bending on one side, on one side lead end Son expands into splayed (truncated cone) to the 2nd temporary bending of root, and then temporary bending is required The time of wanting is segmented shortening, and temporary bending is rapidization further, the batch of aluminium electrolutic capacitor Production efficiency (manufacturing efficient) further improves.
In addition, if make rotation roller pushing lead terminal freely, undertaken by the idle running of roller Formal crooked, then because the transmission of the pushing force from formal bending die to lead terminal is inhibited, The tensile force that produces at lead terminal is very little, so formal bending can promptly be carried out.
If central portion is being made herringbone, both ends are made on the smooth mould main body, be combined to form groove and integrally mobile with the mould main body, the insulation seat board be directed to do not become the mould main body carry out crooked obstacle the position ways and constitute the temporary bending mould, then at first lead terminal is expanded with the central herringbone portion of mould main body, guiding and be contacted with the par at two ends on the inclined-plane of central herringbone portion simultaneously, lead terminal can be made the temporary bending mould rise at a high speed by successfully crooked.And then, just can expand into splayed (truncated cone) to lead terminal up to its root with the very little stroke of temporary bending mould.
So, the temporary bending mould is risen at a high speed, and with the very little stroke of temporary bending mould temporary bending lead terminal efficiently just, temporary bending can promptly carry out.
Also can the par be set and being molded as herringbone, in this occasion, lead terminal can be successfully crooked continuously.In addition, if lambdoid inclined-plane is not to make continuous inclined-plane, but below reduce the inclination angle and make mild inclined-plane, then can not only guarantee continuous bending but also reduce stroke.
If formal bending die have rotation freely roller and constitute, then because roller pushes lead terminal while dallying, so be inhibited from of the transmission of formal bending die to the pushing force of lead terminal, the tensile force that produces on lead terminal is minimum, there is not lead terminal to be pulled from its root, or the damage of the head lower surface of aluminium electrolytic capacitor, can prevent substandard products.In addition, do not have to produce the danger that pulls, damages, do not peel off the facial mask of lead terminal yet.Thereby formal bending can promptly be carried out.
If adopt above-mentioned manufacturing process on the machine for automatic working of having adorned rotary table, then sending to the intermittence of rotary table can high speed, and the batch process efficient of aluminium electrolytic capacitor improves by leaps and bounds.
