Technical field of the present invention

The present invention relates at an element, preferably a cover for mobile phone covers with forme and with the method for intaglio plate bat printing forme bat printing conductive pattern.

The background of invention

Utilize existing class formation on the market, method that might be by being called intaglio plate bat printing (padprnting) with the design transfer on the plane forme to being flat basically or for example spheroid and mobile phone front etc. only have on the surface of some arcs.If people wish more carrying out the intaglio plate bat printing on the complex surfaces, these surfaces for example mobile phone cap inboard also have arc and/or bending surface like that except the corner is arranged, and so present intaglio plate transfer-print technology will be not enough to deal with.Because bedding and padding are not except can only having on the side having on the bottom surface the pigment.Bedding and padding are when running into forme, directly from top acquisition pigment.Thereby present forme can only carry out the intaglio plate bat printing on the element that an interface is only arranged.In addition, utilize bedding and padding inaccessible and be difficult on the recess of element and protuberance, carry out the intaglio plate bat printing, because forme can not be transferred to the pigment of abundance on these protrusions and/or recessed portion of element.Utilize above-mentioned other known methods in addition, for example vacuum vapor deposition method and spraying process also can make on these unary inaccessible positions and obtain conductive layer, but its application cost is than intaglio plate bat printing height, because except other factors, people will deduct the required expense of pigment that should not exist on pigment position such as hole, annex and the leading flank.Owing to only print the image that needs, so also do not lose pigment.The machine that also has this kind method to use is more cheap.This kind method also is easy to automation, so operating cost is lower.Therefore people have considerable interest to solving the problem that exists in the intaglio plate pad printing method.These problems are how to make to carry out the intaglio plate bat printing become possibility on corner portions, peripheral side, curved surface, bending side.Should understand, Eric Cooper letter (Ericsson) company has numerous relating to specially at cover for mobile phone and covers the process patent application of carrying out the intaglio plate bat printing.

Summary of the invention

So, the objective of the invention is to eliminate the shortcoming that said structure has, way is to make the shape of forme meet the shape of bedding and padding, make again bedding and padding shape equivalence element may have recessed, protrude and the shape on bending surface, thereby make element at least one connect side and can print simultaneously.Owing to have the passage that the air built up in will on the element corner and other caves is discharged on the forme, so this forme no longer can not be used for pigment is transferred to the described position that is difficult to arrive of bedding and padding.

Because the present invention, people can make the suit the requirements element of intaglio plate bat printing of the outward appearance of forme and shape now, and way is that forme is divided into the smaller parts that is shaped by different way, and they can for example be flat, recessed, combinations that protrude or these shapes.According to the present invention, these parts or with fixing or interosculate with manner and to form a complete forme.According to the present invention, one of part at least of this forme is represented at least one corner or its lip-deep at least one radius of corner that is made of at least two sides at an angle to each other.When pigment application to forme the time, is adopted a spreader that sweeps away motion in the above, thereby the pigment application that will give determined number is on forme at least one recess, so set up a pattern.This point can be carried out with distinct methods.One of them is set level all parts of movable forme when coating pigment.Another method is when coating will be transferred to the pigment that bedding and padding get on, and makes the shape bending forming of forme according to bedding and padding.Bedding and padding are motion from top to bottom mainly, collides forme then, and at this moment, forme can be shaped according to the bedding and padding shape, and way is to utilize at least one to be connected with the forme part, and at least one forme part can be installed in the arm that gives on the allocation.Therefore, the forme after the shaping can reach the part of each preparation coating pigment on the bedding and padding, thus just transferable pigment.Another method that pigment is transferred on the bedding and padding is to depress a cushion, it is flattened on the forme bottom surface after the shaping, thereby in cushion, will produce counter-pressure, this pressure causes the bedding and padding distortion again, because this distortion, bedding and padding are expanded on other direction, and at least one is furnished with the bending and/or the curved side of pigment thereby touch forme, by this mode pigment is transferred on the bedding and padding.At least one passage and/or at least one hole by a corner from forme will be drained owing to one air that bedding and padding form in this corner when forme is depressed, and this just prevents pigment deposit on the corner of forme and other inaccessible positions.In a preferential embodiment of the present invention, at first from bending, but the pigment that obtains on inactive forme side to be coated on the forme and opened by cloth, thereby pattern is decided in giving of having obtained.For with pattern attached on the bedding and padding side, the shape of forme should be corresponding with the shape of bedding and padding.Pigment cloth is placed on the spreader on the forme because be movable the installation, so the ability according to the motion of forme irregular surface is arranged.Spreader can be fixed on the axle, makes it to give the swing of fixed motion mode, perhaps can be placed in the track that meets the forme shape to move., plastics can be finished on forme and rotatablely move.In the case, at first the side should be leaned against on the forme, make it obtain pigment, bedding and padding continue to rotatablely move then, and continue to contact with forme, thereby continuously change the application angle towards forme, make remaining pattern attached on the bedding and padding like this.According to the present invention, people also can consider the interface of equipment activity on forme, and it is flat that its position becomes whole forme when coating pigment.In the case, spreader just sweeps away whole surface, pigment is pressed in the indenture of forme.Before bedding and padding were obtained pigment from forme, it is corresponding with the shape of bedding and padding that the shape of forme has become, and way is forme with the soft material manufacturing and/or has the linkage that connects with other forme parts, drives forme then and make its bending.By this mode, pigment can be transferred on the different interfaces of bedding and padding.When the element with the inboard shape of mobile phone cap was carried out the intaglio plate bat printing, the forme of the preferred embodiment of the present invention was one mainly to contain the box of planar base surface, and the bottom surface of box for example has four basic vertical sides to be connected with it.When in the etching cavity of spreader at forme during coating pigment, the side and the bottom surface of forme all lay flat on one's back.After this just the side is placed mainly vertical position.Bedding and padding divide three phases to obtain pigment from forme now.At first obtain pattern from the forme bottom surface by the pressurization bedding and padding, in second stage, owing to continue the compression bedding and padding, make the bottom surface distortion of bedding and padding, this distortion is propagated in bedding and padding, thereby make its at least one existing side and the vertical substantially contacts side surfaces of forme, the pigment on these sides is also transferred on the bedding and padding thus.According to the present invention, in the phase III, the corner portion of bedding and padding is pressed into the corner portion of forme.Overhead air-capacitor is easily built up in these corners, and the air duct and/or the steam vent that just need to be connected with the corner on the forme will stop pigment to be drained attached to the air of the gathering on the forme.According to the present invention, people also can consider a kind of bedding and padding that comprise a swiveling wheel, and this swiveling wheel is by obtaining pattern on the wheel shape forme with identical speed rotation.The method that above-mentioned minute three phases transferred to pigment on the bedding and padding from forme also can be used for rotating on the forme, and this forme has bottom surface and the side that a cross section is " U " font.The bedding and padding of its bottom surface compression rotation, thus the bedding and padding side can be pressed on the side of forme.Have respective shapes by this and pattern can be transferred on the bedding and padding from forme,, have corner, curved side and bending side although it is complex-shaped with the method for the forme on surface with flat, flexible and bending.Great advantage of the present invention is that people can utilize more a spot of printing bedding and padding and faster speed to carry out the intaglio plate bat printing of pattern on complex surface.The present invention is specially adapted to rotate forme and rotation bedding and padding.In addition, by hole and passage, people remain in the air accumulation problem on the corner when having solved the intaglio plate bat printing.

The detailed description of the preferred embodiment of the invention

From as can be known embodiment illustrated in fig. 1, device of the present invention comprises one and handles the forme 1 of pad printing method in the phase I, it is flat partial printing 2 substantially that forme has a plurality of, by linkage 3 it can be connected to each other together versatilely, linkage can upwards rotate partial printing around linkage 3 by direction of rotation 4.Make seam 6 on the forme 1, partial printing 2 Zhe that can make progress is risen, with a spreader coating pigment 5, thereby form pattern 5 at the recess of forme 1, this moment is the specific otch 7 of selected position layout on forme 1 for example.In the case, pattern 5 is a conductive layer, and bedding and padding are obtained behind this conductive layer the intaglio plate bat printing to the inboard of mobile phone cap again.Otch 7 comprises the hole in the layer, in order to slot millings such as the earplug of giving mobile phone, loudspeaker, antenna, contacts.

From as can be known embodiment illustrated in fig. 2, forme shown in Figure 1 is in the second stage of pad printing method, this moment partial printing 2 by a mechanism around linkage 3 upwards Zhe rise.This mechanism links to each other with at least one partial printing 2 by device 10 the most handy mechanical means, in order to drive these partial printings, makes it be in vertical substantially position.On this position, forme 1 is basically as the individual box that conforms to the inboard shape of mobile phone cap.Very natural people can consider that partial printing 2 also can have the position of some bending, thereby and not exclusively erect.Shape basically with the inboard similar bedding and padding of mobile phone cap can obtain from the forme 1 of obtaining side pattern 8 and bottom surface pattern 9 on this position pattern 5 then the intaglio plate bat printing to the inboard of mobile phone cap.

Be in the second stage of Fig. 2 pad printing method from embodiment as can be known shown in Figure 3.Forme 1 by elastomeric material for example metallic plate make, it is by installing the side 30 that to make its at least one position be a bending, 10 positions that obtain, or is the bending side 8 according to Fig. 2.Before be coated with pigment on the position keeping flat according to the above-mentioned stage 1.If the forme shape is nonvolatil, because of rather than movable, so just can not be according to the described coated pattern 5 of Fig. 1.Or alternatively must make spreader 11 according to giving fixed motor pattern motion, so that contact with forme at any time, thereby even this forme has a plurality of bendings and/or crooked side, pigment can be coated with on whole forme open.Comprise that therefore one section 12 distance the fixing point 18 on the arm 13 from forme 1 surface to spreader 11 must match with application angle 14, make when spreader 11 motions, at least one leg 16 on the spreader can be pressed in pigment on the recess 17 of forme, thereby spreader leans against on the forme in its whole motor pattern.In order to reach this point, arm 13 should be able to be contained on the guide rail 19 versatilely, and guide rail 19 is fixed on again on the pad printing machine that is used for pad printing method somewhere.In guide rail 19, the shape that has a guide portion 20 at least is at least one track or similar track, and its effect is spreader can be finished give fixed motion.Can have an extra fixing point 21 on the same arm 13, this point also is fixed on the guide rail 19 movably, thus when arm 13 when guide rail 19 moves, can change its application angle 14.According to the present invention, forme also can have partial printing 26 on 1 side, and is according to above Fig. 1 and 2, this partial printing 26 on forme 1 be can be movable or nonvolatil.Can replenish the spreader 11 of pigment cloth being put into the recess 17 on the partial printing 26 at that time, so that also set up pattern 5 at these positions.With the method just can of bedding and padding with upper side on the cloth paint.

By as can be known embodiment illustrated in fig. 4, a plurality of formes 22 are housed in the circumferential area of swiveling wheel 27, wheel 27 is installed on the axle 23, thereby can rotate in direction 24.During rotation with spreader 11 coating pigments, thereby make forme 22 in a continuous process, form a pattern 5, that is except rotating because of wheel 27, spreader 11 need not by beyond guide portion 20 motions, and pattern 5 forms according to the described mode of Fig. 3 one by one on the forme.But application angle 14 and/or distance 12 must be able to change when rotated.

By forme shown in Figure 5 as can be known, it has 4 sides 8 that are in vertical position basically, thereby forms the corner on forme.Bedding and padding are obtained the pattern of coating on the forme 1.When bedding and padding pressed downward in the forme 1, some air was compressed in the forme, and in the case, this air can be overflowed by the hole on the corner 29, so bedding and padding just can be obtained the whole pattern 5 that also comprises forme 1 corner.In claims, the statement of " the complementary cooperation " is used to illustrate the correlation of forme shape and bedding and padding shape hereinafter.Naturally, this is shaped as the inverted image of bedding and padding shape.So, if bedding and padding have brick shapes, just then forme has box-shape, and fragment of brick (bedding and padding) can fall in the box.Therefore, cassette interior (forme) with respect to brick determine (bedding and padding) have complementary shape.

Above describedly only should be considered as a useful embodiment of the present invention, and the restriction of the content that scope of the present invention only is subjected in the following claims to be put down in writing.
