Embodiment
Now by reference to the accompanying drawings, this novel embodiment is elaborated.
As depicted in figs. 1 and 2, a kind of embodiment of display screen and frame heat pressure adhesive device, comprise Power Component, guide plate 2, heating plate 3, upper die plate 4, counterdie 5, counterdie positioning plate 6 and body 7 from top to bottom successively, in the present embodiment, Power Component adopts Pneumatic assembly 1, in other embodiments, Power Component can adopt other modes.
As shown in Figures 1 to 3, described guide plate 2 is connected with heating plate 3 elasticity by spring 8, heating plate 3 bottom surface is provided with seal ring 9, sealing circle 9 exceeds the bottom surface of heating plate 3, cavity is formed between heating plate 3 lower surface and upper die plate 4 upper surface, vacuumize this cavity, upper die plate 4 is just adsorbed on below heating plate 3.Counterdie 5 is removably fixing with counterdie positioning plate 6.Pneumatic assembly 1 drives guide plate 2, heating plate 3 and upper die plate 4, and relative counterdie 5 and counterdie positioning plate 6 move up and down, for die sinking and mold closing together.Heating plate 3 pairs of upper die plates 4 conduct heat for melting the hot melt adhesive in mould between display screen and support, thus are bonded on support by display screen.
In some embodiments, upper die plate 4 by the negative-pressure adsorption in cavity below heating plate 3.In other embodiments, upper die plate 4 is adsorbed on the lower surface of heating plate 3 by electromagnetic force.
The contiguous chute place of described body 7 upper surface is provided with the position limit switch 11 for responding to counterdie positioning plate position.
As shown in Figure 3, adopt elasticity to be connected between guide plate 2 with heating plate 3, therefore automatically can correct the parallelism between upper die plate 4 and counterdie 5, template is stressed and be heated evenly.And whole hot table 3 is fitted and on upper die plate 4, hot area is large, heating is fast.
As shown in Figure 1 and Figure 4, body 7 surface is provided with chute 71, for placing counterdie positioning plate 6 and locating it.Turbofan 10 is provided with, for generation of suction below the chute of body 7.At the upper casing 72 of described body 7, counterdie positioning plate 6 and counterdie 5 to the position of turbofan 10 being equipped with through hole.When display screen and the pneumatic hot pressing of support complete, before die sinking, the suction of turbofan 10 through the through hole on the upper casing 72 of body 7, counterdie positioning plate and counterdie just display screen be adsorbed on counterdie, prevent display screen from upwards rebounding, meanwhile, display screen is dispelled the heat.
During the template replacement of this new-type display screen and frame heat pressure adhesive device, comprise the following steps:
1. during mould unloading, control handle is adjusted to and unloads film shelves, Pneumatic assembly 1 promotes guide plate 2, heating plate 3 moves downward together with upper film 4 in startup, after described upper die plate 4 and lower plate 5 close up, remove the absorption between described heating plate 3 and upper die plate 4, described Power Component drives guide plate 2 and heating plate 2 to move upward subsequently, and described upper die plate 4 is stayed on lower plate 5, takes off described upper die plate 4 and lower plate 5;
2. during patrix, control handle is adjusted to patrix shelves, first lower plate 5 and lower film positioning plate 6 is fixed, then upper die plate 4 and lower plate 5 are closed up, startup Pneumatic assembly promotion guide plate 2, heating plate 3 move downward together, and are adsorbed on heating plate by upper die plate.
In some embodiments, absorption between described heating plate 3 and upper die plate 4 can be realized by the negative pressure in cavity set between heating plate 3 lower surface and upper die plate 4 upper surface, when removing described absorption, the cavity between heating plate 3 lower surface and upper die plate 4 upper surface can be injected air.In other embodiments, the absorption between described heating plate 3 and upper die plate 4 also can be realized by the electromagnetic attraction between heating plate 3 lower surface and upper die plate 4 upper surface, when removing described absorption, and can by power-off to eliminate electromagnetic force.
In some embodiments, can the position information of position limit switch 11 be received by PLC and start the work of Pneumatic assembly 1.
This new device replacing template operation is simple, the time is short.During mould unloading, control handle is adjusted to and unloads film shelves, and counterdie positioning plate 6 is pushed into contacts with position limit switch 11, Pneumatic assembly 1 promotes guide plate 2, heating plate 3 moves downward together with upper film 4 in startup, until bolster closes up, and the adsorption force then between Rapid reversal heating plate 3 and upper die plate 4, now Pneumatic assembly 1 drives guide plate 2 and heating plate 3 to move upward, upper die plate 4 is stayed on counterdie 5, is then unloaded together by bolster plate, thus can mould unloading rapidly.During upper die plate, be adjusted to film shelves, first counterdie 5 is fixed on counterdie positioning plate 6, again upper die plate 4 is directly positioned on counterdie 5, Pneumatic assembly 1 promotes guide plate 2, heating plate 3 moves downward together in startup, be adsorbed on heating plate 3 by upper die plate 4, just complete upper die plate, bolster contraposition is quite easy.
Should be understood that, above embodiment only in order to this novel technological scheme to be described, is not intended to limit, for a person skilled in the art, technological scheme described in above-described embodiment can be modified, or equivalent replacement is carried out to wherein portion of techniques feature; And these amendments and replacement, all should belong to the protection domain of these novel claims.
