Description
Technical field
The present invention relates to a kind of material that hardens by under electromagnetic radiation that is used for making, particularly the body of a motor car of the object of forming by the paint of UV (ultraviolet ray) paint or heat hardening-particularly-the device that hardens of coating, have
A) at least one produces the transmitter of electromagnetic radiation;
B) near induction system that object is transported to the transmitter and removes again.
Background technology
The paint that hardens under the UV light action is mainly used to paint allergen up to now, for example timber or plastics.The there this paint advantage particularly in, they can polymerization under low-down temperature.Prevent that thus object materials from decomposing or gas is separated out (and destruction).Other advantage in addition but coating material hardens under the UV light action, this makes this painting method also be used in the application in other field now.Here particularly involve short firm time, this particularly directly shows with the painting method of the method work of passing through continuously the time aspect the shortening of device length.This brings huge cost savings.Can dwindle simultaneously the device of the gas that is used for regulating the adding apparatus cavity, this helps to save cost equally.Even at last can stand the object of higher hardening temperature owing to save energy for the sort of, and heat energy particularly, low operating temperature also is favourable.
A plurality of people like the object with the coating of UV hardened material, body of a motor car for example, have quite uneven, usually be the surface of three-dimensional bending, therefore be difficult to accomplish this object is put into the radiation area of UV transmitter, make all surface have roughly the same distance, and make the UV ray show the right angle greatly to be applied on the object corresponding surface region from the UV transmitter.
Start the known the sort of device that is used in up to now in timber and the plastics industry of described type, to this and inapplicable because the UV transmitter is provided with to such an extent that can not move here, and object by induction system along fixing basically orientation from UV transmitter bypass mistake.
Developed a kind of paint recently, they harden in inert gas atmosphere under heat effect for this reason, form stone surface.Can use diverse ways, for example by convection current or by RF transmitter input heat.Under latter event, exist to be similar to the front, that is to say and wait that all surface that paints object should pass through from RF transmitter is other with roughly the same distance for the described problem of employing UV transmitter.
Summary of the invention
The objective of the invention is, the device of the described type of design beginning in this wise makes and can be hardened in the particularly coating on the body of a motor car of complicated uneven object that be shaped, strong with good result.
Realize by such method according to this purpose of the present invention, be that induction system comprises that one has the band hoistable platform dolly of walking mechanism, it has one with respect to the adjustable for height motor-driven hoistable platform that is used for installing object of walking mechanism, and at least one transmitter is provided with in this wise, makes band hoistable platform dolly can pass below at least one transmitter together with the object that is installed in above it.
The present invention is based upon on the basis of this understanding, promptly can make the motion of vertical direction and the translational motion stack of along continuous straight runs easily with this band hoistable platform dolly with adjustable for height hoistable platform.This makes the object on band hoistable platform dolly to pass below at least one transmitter, and at this moment change the height of hoistable platform in this wise, make be contained in object above it on all surface zone, be subjected to uniform amount of radiation and radiation intensity-just as for material harden desired.Only that is to say and shine coating with the intensity that surpasses a threshold value on the one hand, just occur hardening fully when this intensity is maintained in the official hour section on the other hand in electromagnetic radiation.When intensity is too low, do not take place or just carry out polymerisation by halves; Even irradiation time too in short-term-during in enough intensity-equally only reach incomplete sclerosis.
If can be motor-driven with respect to walking mechanism tilt according to a kind of particularly preferred structure hoistable platform of the present invention, so this band hoistable platform dolly can also have widely to be used.Here inclination can be around the longitudinal axis of dolly transverse axis, dolly or is carried out around two axis simultaneously.
Around the feasible translational motion that can abandon along continuous straight runs in some cases of the possibility of transverse axis inclination, because now object can also to be arranged on a transmitter or the large tracts of land transmitter in the plane directed in this wise with respect to a plurality of in many cases, the zone of having passed by in the surface that makes object make progress can also be subjected to the electromagnetic radiation of q.s.
If be provided with side transmitter and object have strong injustice fluctuation or alternate manner on its side profile, just so around the tiltable advantageous particularly of the dolly longitudinal axis.
For example by the tiltable of such method realization around sloping shaft, promptly main platform comprises two support plates, and they are separated from each other by at least one adjustable length push rod.This push rod for example is can hydraulic operated telescopic oil cylinder.At least two push rods of tiltable sexual needs around two sloping shafts.
A kind of like this form of implementation of the present invention is preferred especially in addition, device has the container of a band opening in this form of implementation, object can pass this opening and send in the container by the Height Adjustment of hoistable platform, and at this moment container intracavity can be with at least one transmitter electromagnetic radiation irradiation.This container is used for making electromagnetic radiation and gas not to overflow from side direction, and this should be avoided for the reason of operator's health.Here container can be made the bottom that correspondingly covers of independently parts, passage or cabin shape housing or top or the like.
Transmitter on container or interior layout can be different:
For example can be on chamber wall, at least one transmitter is installed in top or bottom.Wherein when pending body surface three-dimensional is crooked, preferably adopt such scheme, promptly in being parallel on the mutual aspectant sidewall that the movement of objects direction distributes of container, at least one in two end walls that distribute perpendicular to the movement of objects direction and at least one transmitter is installed on top or bottom.On all sides of object or surf zone, can be subjected to electromagnetic radiation without a doubt like this.
Certainly a kind of like this form of implementation of the present invention can be used the most omnipotently, promptly at all walls of container with on a top or a bottom a plurality of transmitters are set.
Described in the above transmitter is arranged on that transmitter constitutes flat emitters basically in the form of implementation at chamber wall or top.
But also can advantageously adopt and make rectilinear transmitter.A kind of like this form of implementation advantageous particularly of the present invention in this case, promptly a plurality of transmitters are arranged on the bridge shape portal frame, and portal frame has arm and substantially horizontal basic limit of two perpendicular.Here pending object just can " pass " between the upright arm of portal frame.
The layout of transmitter on the arm of the perpendicular of portal frame can be complementary with the side surface curve of object.Even when the side profile of object is crooked, also can reach all even sclerosis completely of object side finishing coat thus.
If object surperficial bends down, so transmitter on substantially horizontal basic limit layout and the curve on object surface down be complementary, may be favourable.The layout of transmitter this segmented on level base limit can make object in this wise from the other process of transmitter, and transmitter is remained unchanged substantially from the distance on object surface down.
If give container intracavity input protection gas, then advantageous particularly.Protective gas at first has such function, promptly prevents to have oxygen in the radiation area of transmitter, because oxygen particularly can be transformed into harmful ozone under the UV light action, it also damages the process of polymerisation in addition.
Having one at container and be used for making when object enters up or towards the opening of side, if protective gas is heavier than air, is particularly advantageous.Here for example can consider carbon dioxide.
Have one when being used for making object enters down opening at container, if protective gas lta, then advantageous particularly.Here for example can consider helium.
If near near at least one transmitter a gas atmosphere inlet is arranged, it simultaneously can be as the refrigerating gas of transmitter so.But additionally also can arrange at least one inlet alternatively or in addition in this wise, make the protective gas that comes out from entering the mouth directly aim at the surface of shining at that time.Guarantee in this way, impel the deal of the undesirable foreign gas of reactive site of sclerosis very little in electromagnetic radiation.
If on a side of object dorsad, set a movably reflector at least one transmitter, transmit direction and pending object surfaces curve are complementary.
Container part at least can apply the reflecting layer.Can adopt the transmitter of smaller power thus.
If the reflecting layer is not flat here, then advantageous particularly.Under this condition, reflect and undertaken, thereby make container intracavity be full of the electromagnetic radiation of the extremely different directions of propagation very equably by different angles.
For example can consider aluminium foil as reflector material, because it has extraordinary albedo for electromagnetic radiation, and cheap, in addition thus can be easily, that is, realize uneven reflecting layer by wrinkling aluminium foil.
Device of the present invention should have a cabin shell, and it prevents not controlled the leaking of gas and electromagnetic radiation.The two health for the operator is harmful to.
At the entrance and exit place of cabin shell one gate that is used to the hoistable platform dolly is set respectively.These gates prevent that a large amount of air enter in the shell of cabin from outside atmosphere when transport trolley enters or leave the cabin shell.The effect of electromagnetic radiation that these flood tide gate protection operating personnel avoid being harmful to health.
In addition,, be suitable in the gate of inlet side, being provided with in this wise another gas atmosphere inlet, make to dash with protective gas and drench cavity, can squeeze away the air that its inside is comprised thus for having the object of cavity.
But because with gate can not stop fully air particularly oxygen clamp-on cabin shell inner chamber, a device that is used for oxygen discharge is arranged in the atmosphere of shell inside, cabin is set suits.This device can comprise the catalyst converter that is used for making the oxygen catalyzed combination, is used for absorbing or the filter of adsorption of oxygen.
If coating material is as also comprising many solvents the situation of for example water-based paints when beginning, can have a preheating zone in order from coating material, to remove this device of solvent so.And handle dusty material if desired, the gelation device for this dusty material can have a corresponding preheating zone so.
Next it is contemplated that device has the thermal treatment zone, a back, so that sclerosis fully.At this moment the sclerous reaction that triggers by electromagnetic radiation can be proceeded in the thermal treatment zone, back, till coating is hardened fully.
If the operator can monitor irradiation process and according to the appearance profile control corresponding lifting of hoistable platform of irradiated object and the banking motion that also has sometimes, be with the hoistable platform dolly also can manually control so by naked eyes in principle.But device preferably has a control device, and it controls the height of hoistable platform automatically according to object appearance profile up.
The height of hoistable platform can change in this wise by control device, make object during the other translational motion of at least one transmitter between object and this at least one transmitter vertically distance remain unchanged at least approx.Guarantee that in this way object whole surf zone up is subjected to identical radiation intensity and roughly the same amount of radiation, that is identical irradiation on the meaning of optical measurement.
The spatial form data of the needed object of this control can be provided by the data processing equipment of upper level.But this device also can oneself be measured these cavity shape data.Along throughput direction the measurement station was set before at least one transmitter for this reason, can measures the spatial form data of object by it.
Measure station and only comprise one or several grating in a kind of special simple structure, they preferably directly are contained near at least one transmitter, and with the control device acting in conjunction.If pending object interrupts a grating, just can provide the corresponding movement warp of object in real time so.
Have at least one optical measuring head if measure station, it for example can comprise the infrared-ray source, can measure object at a scanning direction at least by it, just measurement space shape so accurately.Accurately the another kind of possibility of measurement space shape is the digital processing and the identification of object shooting figure, measures station like this and should have a video camera and digital image recognition device.
Particularly also must carry out translational motion at object band hoistable platform dolly when below portal frame, passing this form of implementation on the band hoistable platform dolly.Because the coating on the object is subjected to the time of electromagnetic radiation should be too not short, this translational motion can not be done to such an extent that how soon at will have.If band hoistable platform dolly passes portal frame lentamente, and after giving induction system with object then again zero load return to its starting point, this process should need to spend many times so.
If therefore induction system comprises that just in time a band hoistable platform dolly and is used for the running rail of this dolly, this is favourable, along this track at least one transmitter is set, wherein be used for installing object to the installation station of hoistable platform and the payment station that is used for exporting object spatially overlap.This layout is impelled, and band hoistable platform dolly is together with the object twice that is contained in above it, that is once along direction of advance, other process once along direction of retreat from least one transmitter, and come back to its starting point thus.Object can be taken off from hoistable platform there, it is just vacated then, so that new object to be illuminated to be installed.Can roughly double when this structure from the translational speed of the other process of at least one transmitter, because all surface district stands electromagnetic radiation twice.This structure of the present invention needs less parts.
If induction system comprises at least two band hoistable platform dollies, can realize higher output so, wherein be used for object being installed in the installation station on the hoistable platform and be used for paying between the payment station of object and lay two running rails that are used for dolly in this wise, band hoistable platform dolly can be circulated in the loop of a sealing station being installed and being paid between the station.
Electromagnetic radiation is UV light or infrared ray preferably.

Secondly inner chamber 30 is connected with a regeneration loop, and it has such purpose, and the oxygen of soon bringing inner chamber 30 into by body of a motor car 12 or clamp-oning inner chamber at unlatching access hatch 34 or when going out port strobe 36 is removed from the atmosphere that is full of inner chamber 30.Constantly take out gases in the inner chamber 30 by pipeline 43 for this reason and for example make it by a catalyst converter 39 that makes the oxygen catalyzed combination.The part of these gases feeds back to the inner chamber 30 of cabin shell 28 again by pipeline 47, and another part is in piping 51 is discharged into extraneous atmosphere.
On the bottom surface 45 of container 38, install one totally with the 46 band hoistable platform dollies of representing, and can continue to use the direction translational motion of double-head arrow 48 expressions, adopt a drive unit that in Fig. 1, does not draw in detail that is installed on the band hoistable platform dolly 46 for this reason.Band hoistable platform dolly 46 has a walking mechanism 50 and a lowering or hoisting gear 52, and as known in the prior art, it for example can make fluid power or power-actuated scissors transmission device.Being used for the end up of lowering or hoisting gear 52 of mounting bracket 16 forms a hoistable platform 54.This hoistable platform 54 also can be made up of a framework that connects shear arm movingly in the lowering or hoisting gear 52 of making the scissors transmission device; The notion that is to say " platform " not necessarily must imply the plane that links up.The direction that can continue to use double-head arrow 49 expressions by means of lowering or hoisting gear 52 hoistable platforms 54 vertically moves.
One portal frame 44 is set in container 38 in addition, its details is described below with reference to Fig. 2.
In Fig. 2, represent portal frame 44 with the front view that amplifies.Portal frame 44 bridge-types are crossed over being used to the driving path 56 with 46 walkings of hoistable platform dolly on inner chamber 30 bottom surfaces 45.On portal frame 44, fix top transmitter 58, a pair of downside transmitter 60a that is arranged on the generation UV light of driving path 56 both sides of a generation UV light, 60b, and the upside transmitter 62a that is arranged on driving path 56 both sides, 62b.Top transmitter 58 and four side transmitter 60a, 60b and 62a, 62b-as representing in detail for top transmitter 58 usefulness Reference numerals-comprise a bar-like light source 64 respectively.Each UV transmitter sets a reflector 66 in addition.Here bar-like light source 64 also can replace with a plurality of single sources that are similar to point-like.
Be positioned on body of a motor car 12 inner surfaces in order to make, from the outside by UV transmitter 58,60a, 60b and 62a, the UV lacquer sclerosis that 62b can not arrive, can adopt an additional UV transmitter, it is kept by a movable manipulator (not shown) that can drive body of a motor car 12 inner chambers into.
With the nozzle 68a that pipeline 42 (see figure 1)s are connected, feeding in the zone, bottom surface 45 of 68b below portal frame 44, at run duration by nozzle to UV transmitter 58; 60a, 60b, 62a; spray into carbon dioxide in the slit between 62b and the body of a motor car 12, as protective gas.This protective gas is used for cooling off UV transmitter 58 on the one hand, 60a, and 60b, 62a, 62b extrudes undesirable oxygen containing residual gas on the other hand, and this residual gas causes producing ozone under the UV light action, and may damage polymerisation.
Near aluminium foil 73 coverings that container 38 usefulness are wrinkled around portal frame 44 are reflected so that reach high light.
Above-mentioned curing system 10 is worked as follows:
Suppose in the spray equipment of a preposition painting equipment, to have sprayed a plurality of skin of paints.An outmost skin of paint is a varnish, and it is applied on the skin of paint that has existed as powder.Varnish polymerization and sclerosis in this way under the UV light action.Be that Powdered paint is transformed into a kind of liquid gel state that is bordering in advance on the one hand to this its prerequisite.Adopt preheating zone 18, the body of a motor car of putting in this district 12 is heated to about 90 ℃ temperature for this reason.Powder is transformed into described gel state under this softening temperature.
Then hoistable platform 54 drops to by means of lowering or hoisting gear 52, and the dolly 46 of band hoistable platform and the vehicle body of laying thereon 12 can be moved below top cover 37.At this moment body of a motor car 12 is in the protective atmosphere of injection in container 38 fully.
Other process is described by means of accompanying drawing 3a to 3c below.Wherein represent that according to the view of Fig. 1 the inner chamber 30 of cabin shell 28 is together with container 38, portal frame 44 and band hoistable platform dolly 46 with one respectively.
54 liters of hoistable platforms on the position shown in Fig. 3 a at band hoistable platform dolly are so high, make body of a motor car 12 protecgulum 70 from top transmitter 58 just like be about 30cm for the best theoretical of sclerosis, and band hoistable platform dolly 46 in running rail 56 upper edges with the direction motion of arrow 72 expressions.Hoistable platform 54 drops in the follow-up forward travel process of dolly 46, the roof 74 of body of a motor car 12 is risen now have theoretical from top transmitter 58.This STA representation is in Fig. 3 b.
After proceeding one section forward travel along arrow 72 hoistable platform 54 rise again-as by shown in the arrow 76.Bonnet 80 is also passed by below top transmitter 58 with theoretical now thus.In case in a single day band hoistable platform dolly 46 passes portal frame 44 in the above described manner, the direction of motion of band hoistable platform dolly 4b is just reverse.The technological process of representing by means of Fig. 3 a to 3c just repeats with opposite order.Make body of a motor car 12 sides and surface up stand twice irradiation of UV light in this way.
Again arrive it after the original position shown in Fig. 1 at dolly 46, hoistable platform 54 is elevated to by means of lowering or hoisting gear 52, make support 16 with the bodies of a motor car 12 by its supporting can reach raceway 14 on the subregion 14b shown in Fig. 1 the right.Support 16 by going out port strobe 3b, leaves irradiation unit 20 together with body of a motor car 12 then.
In order to control this process one CCU 90 is set.It particularly has such purpose, i.e. control band hoistable platform dolly 46 along continuous straight runs (double-head arrow 48) and the vertically motion of (double-head arrow 49).Control device 90 has a memory 91 for this reason, in the spatial form data of its inside store automobiles vehicle body 12.These spatial form data can for example access from the upper level data processing equipment, storing for the whole body of a motor car 12 conclusive data of passing curing system 10 in this data processing equipment the inside, as the kind and the color of paint, the type of vehicle body and shape.So only need a reader, the model of the body of a motor car 12 that its identification enters, thus can access the spatial form data that match with this model.
Additionally also can also measure needed spatial form data with a measurement mechanism 80 in addition or for the purpose of control, this measurement mechanism is installed in (see figure 1) within the access hatch 34.Measurement mechanism 80 has a U-shaped pedestal, the optical measuring head 82 of 49 fixing a plurality of band infrared light sources vertically on it.Its exterior contour of scanning survey when optical measuring head 82 passes measurement mechanism 80 at body of a motor car 12.
But it is just enough measurement mechanism to be made simple grating device when required precision is not too high, and it is directly installed near the portal frame 44.The interruption of grating points out that body of a motor car 12 is too near from top transmitter 58 just for control device 90, and hoistable platform 54 must descend.The elevating movement that causes hoistable platform 54 stairsteppings to distribute by this control device is not because grating allows the continuous monitoring appearance profile.
A kind of band hoistable platform dolly 46 ' of expression among Fig. 4 wherein is contained in one and installs four on the support plate 93 on formation one first plane on the lowering or hoisting gear 52 and form rectangular layout push rods 92.But push rod 92 hydraulically extensibles, and can separately stretch out.Constitute the upper end supporting bracket 16 of the push rod 92 on second plane 95.Make the support 16 both can be in this way around a transverse axis together with the body of a motor car 12 that is contained in above it, as among Fig. 4 with shown in the double-head arrow 94, again can be around a vertical axis tilt of dolly 46.
Expression is around this inclination of the longitudinal axis in Fig. 5, and it is fully corresponding to Fig. 2.But with there homonymy transmitter 60a not, 60b and 62a, 62b is arranged vertically.Here reaching body of a motor car 12 sides by its inclination around its longitudinal axis shines uniformly.
The vertical view of Fig. 6 a and 6b is represented the inner chamber 30 by another embodiment of the present invention, and wherein two band hoistable platform dollies 461,462 carry body of a motor car 12 to pass portal frame 44 by the circular flow mode.Also can make plural band hoistable platform dolly by this equipment, make automobile pass portal frame and illuminated with the short beat cycle.This external this embodiment is provided with two by partition wall 96 separated running rails 561 and 562, in two end regions at inner chamber 30 between this running rail 561 and 562, can cause a kind of connection by such method, promptly in partition wall 96, can move into slide 98,100, as shown in Fig. 6 b.
Here two band hoistable platform dollies 461 and 462 circular flow is carried out according to the following steps:
The body of a motor car 12 on first dolly 461 pass portal frame 44 and at this moment stand UV illumination penetrate during, second dolly 462 is in the backhaul on adjacent running rail 562.When first dolly 461 together with body of a motor car 12 through portal frames 44 and irradiated body of a motor car 12 during running rail 561 terminal transfers, slide 100 is just opened, and makes dolly 461 side direction to reach on the adjacent orbit 562.Meanwhile Kong dolly 462 reaches on article one running rail 561 from second running rail 562 by the slide of opening during this period 98 with the opposite direction of motion.Load a body of a motor car 12 to be illuminated at second dolly in this position 462.
The foregoing description is used for hardening under the UV light action and paints.But they also can be used under heat effect, particularly in inert gas atmosphere, that is for example at CO
2Or in the paint that hardens in the nitrogen atmosphere.At this moment only described UV transmitter need be replaced with the IR transmitter basically.Other structural change relevant with the replacing of electromagnetic radiation is well-known for the professional, do not need here to describe in detail.
