Detailed description of the invention
Fig. 1 is the flow chart of a kind of heat-transferring method according to one embodiment of the invention.Fig. 2 to Fig. 7 illustrates the schematic diagram of associated components in Fig. 1 flow process, to correspond to the state in described flow process.Please refer to Fig. 1 and Fig. 2, first, at the step S110 of the present embodiment, be placed in die cavity 300 by membrane 100 and workpiece 200, workpiece 200 is carried on tool 400, and makes membrane 100 be positioned at the top of the surperficial S1 of workpiece 200.
As Figure 2 illustrates, the surperficial S1 of workpiece 200 is divided into multiple different block B1, B2, B3 and B4, at this, according to workpiece 200 surperficial S1 relative to the bottom 310 of die cavity 300 relative altitude and classified, be also about to have same relative altitude or the identical surface of its variation tendency is divided into same block.In illustrated embodiment, the relative altitude of block B1 in die cavity 300 is lower than the relative altitude of block B2 in die cavity 300, and the relative altitude of block B2 in die cavity 300 is lower than the relative altitude of block B3 in die cavity 300, and block B4 is adjacent to the relative both sides of block B1 and has identical variable gradient.
The mode distinguishing described block is not limited at this, in the embodiment that another does not illustrate, also different blocks is distinguished by membrane 100 relative to the distance of surperficial S1 or its variation tendency, and these belong to identical block, it is have identical distance (or identical variation tendency) relative to membrane 300.For example, same for Fig. 2, described block B3 is less than the distance of block B2 relative to membrane 100 relative to the distance of membrane 100, and block B2 is less than the distance of block B1 relative to membrane 100 relative to the distance of membrane 100, and block B4 has identical variable gradient relative to membrane 100.So, the effect of being classified by the surperficial S1 of workpiece 200 can be reached equally.
At block B1, B2 and the B3 of Fig. 2 embodiment, namely its block that relative altitude is higher in die cavity 300 represents its close together relative to membrane 100.Otherwise the block that relative altitude is lower in die cavity 300 then represents its distant relative to membrane 100.But this is only the wherein embodiment meeting above-mentioned two kinds of conditions simultaneously.In the embodiment that another does not illustrate, when membrane 100 is not the surperficial S1 abreast relative to bottom 310 close to workpiece 200 (when membrane 100 is inclination relative to the surperficial S1 of workpiece 200), then above-mentioned two kinds of conditions (relative altitude in die cavity, and relative to the distance of membrane) just cannot meet simultaneously and need look it individually.
What another need one were carried is, the different blocks B1 that surperficial S1 is distinguished, B2, B3 and B4, the quantity of described block is different according to the condition of above-mentioned classification, only illustrates using described four block B1, B2, B3 and B4 as example below, and is not used to limit the present invention.
Hold above-mentioned steps S110 and in step S120, heat and provide the first negative pressure V1 in die cavity 300, being extended these blocks B1, B2, B3 and the B4 that also sequentially can contact above-mentioned surperficial S1 to allow membrane 100.It should be noted that, do not limit heating at this, cool or provide negative pressure in the means of die cavity 300, in the illustrated embodiment, effect that is temperature required and negative pressure can be reached from known heating unit of the prior art (not illustrating) or vacuum unit (not illustrating).Similarly, face to face in time need cooling die cavity 300, the radiation of structure itself, conduction or convection type indirectly can also cool, such as, stop heating to allow die cavity 300 Temperature fall to die cavity 300, or with cooling system known in the art, die cavity 300 is directly cooled.
Then, as shown in Figure 3 and Figure 4, the membrane 100 of the present embodiment has ductility, once be subject to temperature or pressure change just can as shown in the figure as generation gradually distortion.Accordingly, when the membrane 100 of the present embodiment is fixed on die cavity 300 structure in its relative both sides, naturally can be out of shape from centre because of gravity effect.Along with the first negative pressure V1 continue provide, the central authorities of membrane 100 just first can contact the block B1 to surperficial S1.
Another need one are carried, and the membrane 100 of the present embodiment comprises PUR in its composition, formed with hot phase-change material, and along with its state of temperature change.In the present embodiment, when membrane 100 is in the 3rd temperature TP3, membrane 100 and PUR thereof can from initial solid-state distortion, be beneficial to carry out extending or stretching.When membrane 100 is in the first temperature TP1, its PUR just can and contacted object between produce tackness, be attached on this object to allow membrane 100, and when membrane 100 is once be cooled to below the first temperature TP1 (the 3rd preferably above-mentioned temperature TP3), then membrane 100 and PUR thereof just restore to the original state once again, and can not produce stickiness with institute's contact object.That is, now the membrane 100 of state and PUR thereof still keep its ductile characteristic, even if still can keep quick condition with object contact and relative to object move.In addition, when membrane 100 is in the second temperature TP2 (the second temperature TP2 is higher than the first temperature TP1), just make membrane 100 and PUR thereof reach the temperature carrying out pattern transfer printing, be beneficial to the pattern on it to be transferred on the object that contacts with membrane 100.
Based on above-mentioned, in step S120 except the first negative pressure V1 is provided, be that the temperature of die cavity 300 is increased to the 3rd temperature TP3, to allow membrane 100 and PUR thereof start to produce ductility, and the mode as shown in Fig. 3 to Fig. 7 that is able to extends and is contacted with workpiece 200.
Then, in step S130, when membrane 100 contact wherein a block time, heating die cavity 300 to the first temperature TP1, sticks together to make membrane 100 and is fixed on this block be in contact with it.For example, as shown in Figure 4, when membrane 100 has been contacted with block B1, now just heat die cavity 300 to the first temperature TP1 further, to activate the PUR of membrane 100, and make membrane 100 mutually sticked together with block B1 together with and reach fixing effect.In the present embodiment, the first temperature TP1 is 80 DEG C to 100 DEG C, and the 3rd temperature is 60 DEG C to 80 DEG C, but not as limit, and its end relies membrane 100 used and PUR kind thereof and determines.
Then in step S140, condition judgment is carried out to current flow process, namely judge whether the membrane 100 under present situation has sticked together and be fixed on all blocks of workpiece 200, if not, then continue and carry out step S150, namely cool below die cavity 300 to the first temperature TP1 (being wherein preferably down to the 3rd temperature TP3), can continue to make membrane 100 extend and contact other block.As the present embodiment Fig. 4 to Fig. 7 illustrate, after block B1 is fixing with membrane 100, die cavity 300 is cooled to below the first temperature TP1, and thus membrane 100 and PUR thereof are recovered its ductility, so it can be made to continue to extend and be contacted with block B3, B2 and B4.Accordingly, just can repeat above-mentioned steps S130 and S140, and reach and allow membrane 100 sequentially stick together and the effect be fixed together with block B3, B2 and B4.
After membrane 100 to stick together all block B1 to B4 being fixed on the surperficial S1 of workpiece 200 completely via above-mentioned steps, namely in step S160, heating die cavity 300 to the second temperature TP2, and described second temperature TP2 is 80 DEG C to 100 DEG C, there is provided the second negative pressure V2 (the second negative pressure V2 is greater than the first negative pressure V1) to it, the pattern of membrane 100 to be transferred to all block B1 to B4 of workpiece 200 simultaneously.On the other hand, the part that described second negative pressure V2 still can not stick together with workpiece 200 membrane 100 is broken further and is removed, and in this, as the receipts limit action after pattern transfer printing, the edge of pattern on workpiece 200 is able to smooth-going attractive in appearance.Finally, more just workpiece 200 and membrane 100 can be taken out from die cavity 300 after die cavity 300 being cooled in step S170, then membrane 100 be removed from workpiece 200 manufacturing process just completing described hot transfer printing.
Fig. 8 illustrates the Temperature-time graph of a relation of die cavity, to describe the process of above-mentioned Fig. 1 and Fig. 2 to Fig. 7.Please refer to Fig. 1 and Fig. 8, when membrane 100 and workpiece 200 are placed in after in die cavity 300, membrane 100 is made to be contacted with the surperficial S1 of workpiece 200 gradually and to provide suitable temperature according to the corresponding relation between membrane 100 and each block of workpiece 200 (as B1 to B4) by controlling the temperature of die cavity 300.
Say further, after die cavity 300 inserted by membrane 100 and workpiece 200, first heat die cavity 300 in chronomere T0 and make it reach the 3rd temperature TP3, start distortion to allow membrane 100 and extend.Then, after membrane 100 is contacted with block B1, then in chronomere T11, die cavity 300 is heated along with the first providing of negative pressure V1, to make die cavity 300 reach the first temperature TP1, and membrane is sticked together and is fixed on block B1.Again then, cool die cavity 300 in chronomere T12, make it be down to the 3rd temperature TP3 from the first temperature TP1 and allow membrane 100 recover its elongation property, so just can continue to allow membrane 100 extend and other block being contacted with workpiece 200.So, constantly repeat above-mentioned action, and make die cavity 300 carry out heating up at chronomere T11 and the T12 repeated and lower the temperature, until membrane 100 is sticked together completely and is fixed on all blocks of workpiece 200.Finally, in chronomere T13, die cavity 300 is heated to the second temperature TP2 further, and allows the pattern of membrane 100 be transferred to workpiece 200, and cool die cavity 300 in chronomere T14 again and take out membrane 100 and workpiece 200, namely complete the flow process of hot transfer printing.
