Description

Ultrasonic spot welding assembly and method
The invention relates to the ultrasonic welder.More specifically, this application examples is the soldering tip about the ultrasonic spot welding device.
Existing people uses ultrasonic to weld to link multiple material.Generally the most common ground, the ultrasonic welding is used on the thermoplastic material.Reached a kind of ultrasonic spot welding method recently, this type of data please referring to, the Plastics Design Forum in 11-12 month in 1980 for example, the 86th page.The advantage that this publication discloses the ultrasonic spot welding method and cause indefectible outward appearance on the reverse side of welding.The method that the explanation of this piece article welds together two thermoplastic sheets, wherein a standard soldering tip runs through first, and extends to second centre.This piece article also further proposes the possibility of antipoints weldering (inverse spot welding), also be about to soldering tip and be engaged to anchor clamps or anvil, and use the transducer of forming on a plane ultrasonic energy is provided.
The use of ultrasonic spot welding is delivered in it " Ultrasonic Assembly " literary composition illustrating further on the Modern of 1980-1981 Plastics Encyclopedia by R.A. Clarke in the 447-450 page or leaf.In this piece article, Clarke discloses the transducer of ultrasonic spot welding or the general advantage of the toroidal design in the soldering tip.
Previously described ultrasonic spot welding shape or method are not provided at and are used for appropriate device that the melting heat moulding material is flowed out in the welding process from solder joint and soldering tips.The accumulation effect of the molten material in this zone may have influence on the not molten material of weld (because of it absorbs ultrasonic energy), make its continuous melting, facilitate thermal cracking (thermal degradation), thereby cause the Joint Strength deficiency.In addition, molten material may cause that welding head structure is overheated, so may hurt weld and sheet stock on every side.
Disclosed soldering tip comprises that a plurality of transpostion intervals the tapered protuberances of storage space.The modes of emplacement of tapered protuberances is to contact with the material that will weld, and ultrasonic energy is promptly executed material so far.This ultrasonic energy is concentrated, and fused mass is arranged by tapered protuberances and the sheet stock that adjoins these tapered protuberances is heated, thereby softener material.This softener material is arranged by tapered protuberances, and accumulates in the storage space on soldering tip limit, and this storage space provides and is used for piling up the material that this is arranged.This material is softened continuously and is arranged, up to tapered protuberances is rough insert in the sheet material fully till.Tapered protuberances in the preferred embodiment is a normal cone shape, positive rounded or cone shape or pyramid, or adopt and allow the form that it disengages automatically from sheet stock.The structural volume of storage space is significantly greater than the volume of tapered protuberances, to allow the expansion of the material that is arranged.
The invention provides a kind of be used for the system that the multi-disc thermoplastic material is spot-welded together it comprise:
(a) the soldering tip assembly on the surface of approaching this heat-stabilized wood tablet arranged side by side, it comprises an anvil, at least one soldering tip that from anvil, extends, this soldering tip has a bottom that is attached to this anvil, and one above this anvil and with the be separated by summit of a predetermined altitude of this anvil
(b) be used for this soldering tip is inserted the device of surface one segment distance of this sheet arranged side by side, so that at least partly run through each soldered material piece, this distance is less than the height of this soldering tip, with surface that sheet stock is provided and the storage space between this anvil; And
(c) be used for ultrasonic energy is executed to the device near the thermoplastic sheet stock of this soldering tip;
The melting heat moulding material can freely flow in this storage space.
Multiple soldering tip shape can be used on the same seat, and the soldering tip on the anvil can be according to the feature of soldered material, and optionally mounting or dismounting are to provide different soldering tip shapes.
Bonding tip seat is to place along sealing wire, and ultrasonic energy is by bestowing along the transducer of sealing wire extension.The general edge region of this transducer produces more weak ultrasonic energy, such as the top area near transducer.Therefore, in order to compensate the more weak ultrasonic energy in these zones, can make the soldering tip of edge part longer slightly than the soldering tip of zone line, or these soldering tips can be contained in the more shallow countersunk (counterbores) of the anvil that is connected, make the outer diameter of connection soldering tip bigger, thereby can arrange more material.Another kind method is to adopt the transducer of length than bonding wire length, to avoid edge effect.
Among the present invention's first embodiment, soldering tip is a normal cone shape, wherein the above height of anvil is A, is that the ideal ratio of B.A/B is 1.2 in first preferred embodiment in the base diameter on the anvil, is 0.76 in second preferred embodiment.According to these ratios, the weldering end is to disengage (self-releasing) automatically, and runs through sheet stock with minimum energy.
The present invention's main purpose provides a kind of Improvement type ultrasonic welder and method.
Another purpose of the present invention is at the Improvement type ultrasonic spot welding that proposes to be used for the thermoplastic sheet stock.
The present invention's another purpose again provides along the welding of quite long sealing wire, and these welding tool soldering tip shapes, owing to be that moving back of symmetry pulled out shape, when finishing welding, soldering tip will disengage from sheet material automatically.
Another purpose of the present invention provides the fully weldering end of height of a kind of tool, with the support base of formation welding head structure and the natural storage space between the soldering tip itself.

Carry out the present invention's best mode
With reference to figure 1, the present invention's soldering tip (summary is expressed as 10) is to comprise a plurality of tapered protuberances 12, wherein along soldering tip bottom 16, alternately is studded with a plurality of storage spaces 14.Tapered protuberances 12 is used for concentrating ultrasonic energy, and their summits 18 separately are used for contacting sheet stock.This tapered protuberances can adopt the Any shape of the effect that disengages automatically that is suitable for to concentrate ultrasonic energy and helps hereinafter will illustrate, Fig. 1 illustrates a kind of pattern of taper.It should be noted that this " taper " speech is the taper that is used for containing broad sense, and be not limited to normal cone shape, normal cone shape just can be applied in a kind of taper embodiment in the soldering tip of the present invention.
In all soldering tips as shown in Figure 1, the distance between bullet summit and the bottom should be made an appointment with slightly soldered sheet material thickness Doubly.In addition, the width of cone base preferably is about the twice of cone height, or is about 3 times of soldered sheet material thickness.
The situation that the soldering tip 10 of the application examples key diagram 1 of Fig. 2 uses in ultrasonic antipoints soldering method.In order to help the welding of ultrasonic antipoints, soldering tip 10 is to be fixed to anvil or seat iron 20, and this iron 20 is to be positioned on one side of two soldered sheet stocks 30,40.Fig. 2 further specifies supersonic transducer or the horn 50 on the another side that is placed in two sheet stocks, and this two sheet stock is that the dot welding method according to the present invention welds it.
The function of the some weldment shown in Fig. 2 summary is as described below.Soldered material is supported with support member 60, and wherein first and second sheet 30,40th is desired the line parallel arranged along the institute that will weld.The present invention's soldering tip 10 is anvils 20 of placing soldering tip on it through moving, contacts with the one side of first and second sheet stock 30,40 arranged side by side.Simultaneously, supersonic transducer or horn 50 move on perpendicular to the line on the plane of each sheet stock, with the another side of crimping two sheet stocks.Ultrasonic energy is to execute to the sheet stock that will weld via ultrasonic horn 50.When the tapered protuberances 12 of soldering tip 10 during along difference contact sheet stock, ultrasonic energy promptly concentrates in these points.Sheet stock thereby softening.Because the contact of tapered protuberances 12, softening material is arranged.The sheet stock that is softened is to accumulate in the storage space 14, and material is removed from the ultrasonic energy concentrated area, has avoided the overheated of softener material, and ultrasonic energy is focused on not softening material gets on.
Give the depthkeeping degree when spot welding has reached, and tapered protuberances promptly removes ultrasonic energy when inserting sheet stock fully.The cooling of thermoplastic sheet will cause itself shrinking.The shape of tapered protuberances 12 makes soldering tip disengage automatically from sheet material.So, the soldering tip shape of Fig. 1 helps soldering tip to disengage automatically from sheet stock after welding, and through providing storage space that softener material is accumulated in the next door of tapered protuberances l2, so welds to draw Improvement type.
The embodiment of the invention of Fig. 2 is the many anti-dot welding methods of being known of explanation, only also soldering tip of the present invention can be contained in and carry out normal spot welding on the ultrasonic horn 50.
The storage space 14 of figure l weldering end is a hemispherical, and the volume that generally can heap sheet stock is about 15 times of relevant volume that tapered protuberances arranges.It is long-pending that the volume of each storage space should be relevant taper horn at least
Figure A8510606600161
Doubly.
When the present invention's systemic application during in automated production, the residual heat in the soldering tip is piled up (buildup) may cause trouble.If do not have the suitable precautionary measures, the temperature of soldering tip may be high enough to make the sheet stock fusion.With reference to figure 3, wherein represent similar elements with Fig. 1 similar number word, in weldering end 10, provide the cooling duct, so that control its temperature.Through flow velocity or all the other devices of control cooling agent, temperature can be controlled, make soldering tip be maintained until desire temperature.For polyethylene, can be with temperature maintenance at about Fahrenheit 9O °.When the soldering tip temperature arrived 13O ° to 140 ° of Fahrenheit, polyethylene began to adhere to soldering tip.The present invention's soldering tip lO can constitute one or detachable with anvil 20.
Can use in the application-specific example of system of the present invention, must move to the appropriate location to anvil 20 with soldering tip 1O, anvil is placed on the direction that is parallel to the sealing wire that produces.In this implements, do not allow on and move significantly perpendicular to the direction on sheet stock plane.Therefore, the shape of soldering tip preferably makes it slip off from the weldment of finishing along the direction that is parallel to sealing wire.
Fig. 4 is that soldering tip is revised in explanation one in (similar elements is also shown with the similar number word table), wherein the hemispherical storage space of Fig. 1 is that cylindrical groove 22,24 with the both sides of a pair of tapered protuberances l2 that is arranged in arranged crosswise replaces it.These grooves 22,24 are stored partly by a plurality of feed slot and 26 are fed, this store partly 26 with molten materials lead- ingroove 22,24 so that collect.When welding is finished, the soldering tip of Fig. 4 can be parallel on the direction of sealing wire, from with sheet material position arranged side by side remove more easily, because between the tapered protuberances 12 that intersection is scattered, can not build up material significantly, can aggregate material as for 14 of the storage spaces of Fig. 1 embodiment.Therefore, can laterally move this soldering tip more easily.
With reference to figure 5, simple group soldering tip (summary is expressed as 10) comprises a plurality of staggered tapered protuberances 82, and this thrust 82 can be contained in anvil or the gripper shoe 90 with changeing.Between thrust 82, also can use a plurality of usefulness instead and account for the spill storage space R that head is drilled to.These type of a plurality of welding groups generally are to dispose along sealing wire.Tapered protuberances 82 is used for concentrating ultrasonic energy, and each summit 88 that arranges the fused mass thrust then contacts sheet stock.This tapered protuberances 82 can adopt the Any shape that is suitable for to concentrate ultrasonic energy and helps to disengage automatically, and Fig. 5 is a kind of form of explanation taper.It should be noted that " taper " speech is the taper of containing broad sense, be not limited to normal cone shape, normal cone shape is only for using a kind of taper embodiment in soldering tip of the present invention.Say it for example, pyramid also belongs to as one of taper in the range of definition.
Fig. 6 is the enlarged drawing of the single soldering tip of the present invention's first preferred embodiment.Soldering tip 11 is an individual unit, and it comprises a footstalk 83, the bottom 84 of tool diameter B and the tapered protuberances 82 of the tool height A that extends upward of bottom from then on.In all soldering tips as shown in Figure 6, the distance of the height A between summit 88 and the bottom 84 is about two thickness and equates by the single sheet stock thickness in the weld tabs material 3 times.In addition, the make of soldering tip makes preferably that the ratio of width B of height A and bottom 84 is rough to equal 1.2.
The explanation of the side view of Fig. 7 is used for welding the mode of operation of the single soldering tip 11 of the present invention of sheet stock in anti-solder joint method.In order to help ultrasonic antipoints welding, soldering tip 11 is to be fixed to fixedly an anvil or a seat iron 90, and an iron 90 is placed on two tool equal thickness and the one side with sheet stock welded together 100,110.Fig. 7 further specifies the movable horn 120 on the opposing face that is placed on sheet stock, and this sheet stock welds through the present invention's dot welding method.Being installed in horn 120 top forward backstop 86A is effectively to cooperate to limit the downward stroke of horn with fixed stop 86B.When horn 120 descended, it pushed sheet 100 and 110 to soldering tip 81, causes cone 82 to pierce through sheet 110, and a rough half thickness that passes sheet 100, and this runs through degree is that 86B is controlled by backstop 86A.Therefore, the cone 82 rough material piece thickness A that run through 11.5 times.The height of cone 82 is about 3A 1(sheet stock thickness 3 times) so, promptly produces thickness B between sheet stock 110 and anvil 90 1 Free storage space 89.
Ultrasonic energy is to execute to soldered sheet stock via ultrasonic horn 120.When the tapered protuberances 82 of many ultrasonic soldering tips 81 when sealing wire runs through sheet stock, ultrasonic energy is concentrated and fused mass is discharged in these points.Sheet stock thereby softening constitutes melting tank 92 between sheet stock.Also accumulate in the free space 89 between anvil 90 and the material piece 110 such as the molten material at 94 places.As aforementioned, space 89 is caused by backstop 86A and 86B, and it allows that cone 82 only inserts half of sheet stock 110 and sheet stock 100 thickness.The adverse current molten material that ultrasonic welding effect is caused is folded down from sheet stock 100,110 above anvil 90.The fusion sheet stock that flows freely is to remove most molten material from the ultrasonic energy aggregation zone effectively, avoids molten material by superheated.So, ultrasonic energy can preferably concentrate on not on the molten material, to proceed soldering.
When spot welding reached when desiring the degree of depth (1.5 times of the thickness of egative film material 110, positive stop 86A, 86B are controlled this distance), ultrasonic energy promptly stops to supply with, the cooling of thermoplasticity sheet stock will make its contraction.The shape of tapered protuberances 82 makes the cone 82 of soldering tip 81 disengage automatically from sheet stock.
So, Fig. 5,6 and 7 soldering tip shape helps soldering tip to disengage automatically from sheet stock after welding, and melt sheet stock through providing a natural storage space to pile up the major part that flows out the position of sky thing 82, thereby draw the Improvement type welding from sheet stock arranged side by side to taper.
In addition, the soldering tip that height and base portion ratio are about 1.2 head length partly 82 (shown in Fig. 6) can strengthen running through the ability of sheet stock, it is in welding process, and the power source loads of requirement is lower, and appropriate weld strength still is provided.
In addition, the tapering of tapered protuberances 82 is about 45 °, thereby causes the fusing sheet stock that arranges less, and face provides outward appearance to close the welding of people's will.
Fig. 7 embodiment of the present invention illustrates many known anti-dot welding methods, only also can be through soldering tip being contained on the ultrasonic horn 120, so so that the present invention's soldering tip can be applied in the normal spot welding.
The perimeter of ultrasonic welding horn 120 generally is to produce low ultrasonic energy, thereby causes more weak welding outside horn in the region.According to the present invention shown in Figure 8, the soldering tip group W outside anvil seat iron AB in the region 1With W 7The countersunk degree of depth that has (Fig. 7 85), to place the bottom of detachable soldering tip, this countersunk is than all the other the soldering tip group W on the anvil seat iron of sealing wire 2To W 6Shallow approximately 0.010 inch of the countersunk degree of depth.So, soldering tip group W 1To W 7In cone will further be through in the material 100,110.This is the inherent feature that has compensated the low power output of region outside the ultrasonic horn 120.
As shown in Figure 7, the footstalk 83 and the bottom 84 of soldering tip 11 can be installed and removed in the countersunk of anvil body 90, in order to safeguarding and changeing.More importantly, the change of changing places of the number of the every assembly welding head on the anvil and big I, obtaining best weld strength, thereby can be used for the various sheet stocks of more multiple polymeric material of welding and/or tool broad thickness range along sealing wire.Though if any more melting tank, then this group just had higher tension intensity during certain was organized in general.
In the preferred embodiment, the present invention's soldering tip is to be used for spot welding high density polyethylene (HDPE) sheet.Yet the welder that any suitable material all can be used the present invention welds it.
In like manner, the present invention's welding horn and soldering tip can be made by any suitable material.In the preferred embodiment, soldering tip 81 is made of aluminum, and accepts the hard formation anode immediately and handle (hard-coat anodized), to obtain preferable wearing and tearing impedance.This weldering end is handled for the polytetrafluoroethylene (PTFE) of " TEFLON " with brand name subsequently, prevents that surface adhesion firmly.In addition, soldering tip 81 also can be made through appropriate heat treatment by all the other materials such as carbon steel.
If in automated production, use this to count the type system, will in soldering tip, cause residual heat to pile up in the past.Therefore must in anvil, provide the cooling duct, with the temperature of control soldering tip.Among the present invention, pile up through the residual heat that the suitable number of every assembly welding head of sealing wire and geometry can reduce as above to be disclosed.
In addition, because anvil never contact melting material or soldered sheet stock, so pass to hot less on the anvil.
Fig. 9 is the enlarged drawing that is used in the single soldering tip of the present invention's second preferred embodiment in the anti-welding method.Soldering tip 8l is an individual unit, and it comprises a footstalk 83, and diameter is the bottom 84 of B and the frustoconical thrust 82 of the tool height A of extending in the bottom from then on.According to the present invention, we should be appreciated that the soldering tip of Fig. 9 can replace Fig. 5, the soldering tip in 6 and 8.In all soldering tips as shown in Figure 9, the end slightly with bottom 84 between height A be about single sheet stock thickness in the sheet stock that two soldered thickness equate
Figure A8510606600201
Doubly.In addition, the make of soldering tip is preferably and makes the ratio of width B of height A and bottom 84 approximate 0.76.
Fig. 9 also illustrates in anti-solder joint is handled, and is used for welding the second preferred embodiment mode of operation of the single soldering tip 81 of Fig. 9 of sheet stock.In order to help ultrasonic antipoints weldering, soldering tip 81 is fixedly on anvil or the seat iron 90, and it is rough equal and with the material piece l00 that is welded together, on one side of 110 that this anvil 90 is placed on two thickness.Fig. 9 further specifies the movable horn l20 that is placed on the reverse side of the sheet stock of foundation the present invention's dot welding method welding.
According to the soldering tip of Fig. 9, if be necessary that the forward backstop 86A of Fig. 7 can remove, or can keep it.When horn 120 reduces, push sheet stock 100 to soldering tip 81 with l10, cause frustoconical end 82 to pierce through 110 and run through the thickness over half of material piece 100.Certainly, running through degree is to be ended by 82 controls of the frustoconical end more than the shoulder 84S of the bottom 84 of soldering tip 81.82 penetration distances of frustoconical end are the material piece thickness A 1More than 1.5 times.The height of frustoconical end 82 adds that the extended height of bottom 84 of the over top of anvil body 20 is about 3.5A 1(material piece thickness 3.5 times).So, be between sheet stock 110 and anvil 90, to cause thickness B 1 Free storage space 89.
Ultrasonic energy is via ultrasonic horn 120, executes to soldered sheet stock.When 82 more than tapered protuberances 82 of ultrasonic soldering tip when this sealing wire runs through sheet stock, ultrasonic energy promptly concentrates in these points.Sheet stock thereby softening constitutes the melting tank 92 between the sheet stock.Such as the molten material at 94 places is in the free space 89 that is deposited between anvil 90 and the sheet stock 110.As mentioned above, space 89 is partly to be produced with the shoulder 84S of the over top of anvil 90 by the extension of bottom 84, and it is to allow that frustoconical end 82 is inserted in the controlled degree of depth of sheet stock 100,110.As in Fig. 7 embodiment, the adverse current molten material that ultrasonic welding effect is produced will laterally be folded down 94 from the sheet stock 100,110 of anvil 90 tops.Flowing freely of molten material can remove the molten material of major part from the ultrasonic energy concentrated area effectively, avoids the superheated molten material.So, ultrasonic energy can preferably concentrate on not on the softener material, to continue welding.
When spot welding arrived desire the degree of depth (the shoulder 84S of bottom 84 control this distance) and promptly end to apply ultrasonic energy.The cooling of thermoplastic sheet stock causes himself shrinking.The shape of frustoconical end 82 makes the end 82 of soldering tip 81 disengage automatically from sheet stock.
In addition, the shoulder 84S when bottom 84 extends one apart from B in the over top of anvil body 90 1The time, molten material also evenly and radially is dispersed between the sheet arranged side by side, produces well-balanced and a welding that intensity is stronger, this be since the horn application of force make sheet stock 100 and 110 rely on bottom the cause of 84 shoulder 84S.
In addition, the taper on frustoconical end 82 has an angle and is about 45 °, arranges less molten material, and provides an outward appearance more to close the welding of people's will.
