Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is clearly and completely described, to understand fully object of the present invention, scheme and effect.It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the application can combine mutually.
It should be noted that, if no special instructions, when a certain feature is called as " fixing ", " connection " in another feature, it can directly be fixed, be connected in another feature, also can indirectly fix, be connected in another feature.The descriptions such as the upper and lower, left and right that use in the present invention in addition, are only the mutual alignment relation of the each part of the present invention in accompanying drawing.
In addition, unless otherwise defined, all technology that use are herein identical with the implication that those skilled in the art understand conventionally with scientific terminology.The term using in description is herein in order to describe specific embodiment, instead of in order to limit the present invention.Term as used herein " and/or " comprise the combination arbitrarily of one or more relevant Listed Items.
The present invention relates to a kind of adhering method that shows mask, comprising:
S10: the bonding region entirety at display screen applies one deck polyurethane hot melt, it is PU glue-line, PU glue has good heat sensitivity, in the time that temperature exceedes it and solidifies critical-temperature, and thawing that can be very fast, otherwise, when temperature is during lower than critical point, again can very fast solidifying, based on this specific character, select it as matrix layer, reach the effect of Reusability.
S20: on PU glue-line, apply again one deck moisture-curable reaction type polyurethane hot-melt adhesive, i.e. PUR glue-line, preferred, PUR glue-line is only coated in four jiaos of bonding region, and PU glue-line and PUR glue-line form adhesive linkage jointly.The relative PU glue of PUR glue has better heat-resisting quantity, and when adhesive linkage is during in hot environment, PUR, because its heat-resisting quantity becomes the skeleton of adhesive linkage, connects PU glue-line and by gluing of surfaces, makes it can not occur because of high temperature situation about coming off.
S30: will apply the display screen of glue-line and fitted tightly by gluing of surfaces, then pass through pressurization steps, its concrete operations be:
S31: bonding region is applied to certain pressure, while also heats to it, preferably, temperature range is 170 °～180 °, and keep several seconds, now, the temperature of bonding region exceedes the critical-temperature of solidifying of PU glue very soon, PU glue melt, and under the effect of pressure uniform filling to display screen and by the space between gluing of surfaces.
S32: after PU glue melts completely, remove heating source, again it is compressed at normal temperatures, several seconds of same maintenance, the temperature of bonding region is reduced at short notice and solidifies under critical-temperature in the effect of the temperature difference, due to the good heat sensitivity of PU glue, it solidifies rapidly, by display screen with by gluing of surfaces bonding together tightly.
In the time that needs are replaced display screen, only need to repeat S31 and S32 step, the operation that completes dismounting and refitting that just can be very fast.
With reference to Fig. 1, the present invention shows a kind of point gum machine that can carry out double-deck some glue, and it includes base 10, and is arranged on the first guide rail 20 of base 10 tops, it relies on the pillar of two settings to keep the main part of guide rail unsettled with respect to base 10, and can slide along X-axis.The first guide rail 20 is provided with second guide rail 30 perpendicular with it, and it can slide along Y-axis under the effect of external force.
On the second guide rail 30, be provided with the first Glue dripping head 40 and the second Glue dripping head 50, first and second Glue dripping head vertically arranges and can move up and down along Z axis, by the first guide rail 20 and the second guide rail 30, Glue dripping head has the three degree of freedom in X, Y, Z axis, can or progressively complete the movement in above-mentioned three directions simultaneously.
With reference to Fig. 2, on the working face of the first base 10, be provided with the fixed structure for fixed product, preferably, comprise the two places chimb 101 parallel to each other for being socketed product, between both sides chimb 101, form sagging groove, which is provided with some installing holes, for fixed product, be provided with the ejecting mechanism 102 that can move along Z-direction at the two ends of groove.In the time that product is socketed on chimb 101, two ends ejecting mechanism moves upward and withstands product, makes the surface maintenance level of glue-line to be coated, then is locked by securing member, completes fixing.
Also comprise unshowned heater and storing unit, it can melt solid-state PU glue and PUR glue for liquid, conveniently applies.
The coating procedure of this point gum machine is: the first Glue dripping head 40 declines, when after the bonding region on its contact display screen, by the slip of the first guide rail 20 and the second guide rail 30, advancing along X-axis and Y-axis alternately, uniformly PU glue is coated to surface, preferred, mobile route is rectangle.After PU glue has applied, the first Glue dripping head 40 rises, and the second Glue dripping head 50 declines, and carries out the coating operation of PUR glue on the basis of PU glue-line, and preferred, the coating zone of PUR glue is four jiaos of above-mentioned rectangle PU glue-line.
In the present embodiment, the first Glue dripping head 40 is exported PU glue, and the second Glue dripping head 50 is exported PUR glue, and for the present invention, the kind of glue that Glue dripping head is exported is not limited with order, can replace with as required other glue kinds, and some glue order.
With reference to Fig. 3, the present invention also shows a kind of pressurized equipment, comprises the second base 60, the second base 60 is provided with the working face of level, being arranged on working face of the 4th guide rail 601 levels, also comprises the slide 602 for product is installed, and it can horizontally slip along the 4th guide rail 601.
Be provided with limited block 603 at the two ends of the 4th guide rail 601, when slide 602 is conflicted limited block 603 when static, its be just positioned at pressure head under, be convenient to compacting work.
Above the second base 60, be provided with three guide rail 70 parallel with the 4th guide rail 601, be provided with thermal head 80 at its left end, be provided with normal temperature pressure head 90 at its right-hand member, wherein on thermal head 80, be also provided with unshowned heater, it can make thermal head have certain temperature.Under the effect of power source, the two can move up and down along Z axis, and keeps certain pressure.
In the time that product is placed on slide 602, slide 602 is moved to the high order end of the 4th guide rail 601, start the heater on thermal head 80 simultaneously, in the time that temperature stabilization is between 170 °～180 °, thermal head 80 declines, compress product with certain pressure, and maintain certain hour, after hot pressing completes, thermal head 80 rises, slide 602 moves to the low order end of the 4th guide rail 601, similarly, normal temperature pressure head 90, by pressurization and pressurize, completes pressurized operation.
More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the distortion that these are equal to or replacement are all included in the application's claim limited range.
