Embodiment
As shown in Figure 1, be screen detaching device for LCD structural representation of the present invention, present embodiment comprises board 1, following board 2, and last board 1 has last snorkel 41, and following board 2 has following snorkel 42; As the last sucker 31 of adsorbent equipment, be arranged on the snorkel 41, as the following sucker 32 of adsorbent equipment, be arranged on down on the snorkel 42; The last vacuum pump 61 and the following vacuum pump 62 that link to each other with following board 2 with last board 1 respectively by last snorkel 41 and following snorkel 42, and as the resistance wire 8 of heating element.
In the present embodiment, be respectively arranged with at least one sucker on last board 1 and the following board 2, the last sucker 31 of last board 1 is used for the colored filter substrate 11 of adsorption liquid crystal display screen, last sucker 31 is connected with last snorkel 41, be located in the board 1 in last snorkel 41 and the end that last sucker 31 links to each other, the end that last snorkel 41 is gone up board 1 outsides is provided with vacuum pump valve 51, and the break-make by last vacuum pump valve 51 can connect or cut off last vacuum pump 61 and the last snorkel 41 that is positioned at its both sides.The following sucker 32 of following board 2 is used for the TFT substrate 12 of adsorption liquid crystal display screen, following sucker 32 is connected with following snorkel 42, be located at down in the board 2 in following snorkel 42 and the end that following sucker 32 links to each other, one end of 42 times board 2 outsides of following snorkel is provided with down vacuum pump valve 52, can connect or cut off following vacuum pump 62 and the following snorkel 42 that is positioned at its both sides by the break-make of descending vacuum pump valve 52.
LCDs speed is slow, efficient is low at dismantling manually at present, be easy to cause colored filter substrate and TFT substrate crushing, cause the defective that the electric property of LCDs can't analytical test, the present invention proposes a kind of screen detaching device for LCD, fix LCDs by the board up and down that is provided with sucker, and come heating and melting envelope frame glue by resistance wire, reach the purpose of tearing screen open by relatively moving of board up and down then.The present invention has reduced labour intensity, has shortened and has torn open the screen time, has improved the efficient and the success ratio of tearing screen open, thereby makes the efficient of failure analysis be improved.
In the present embodiment, resistance wire 8 is arranged on down on the board 2, and the shape of resistance wire 8 matches with the shape of envelope frame glue 13, is used for heating and melting envelope frame glue 13.Referring to shown in Figure 2, be screen detaching device for LCD rotation work schematic top plan view of the present invention again, resistance wire 8 is connected with resistance wire switch 9, and resistance wire switch 9 is used for the electrical heating of controlling resistance silk 8.In the present embodiment, resistance wire 8 also can be arranged on the board 1, and it will be appreciated by those skilled in the art that in technique scheme, and heating element also can select for use flame spray head, infrared lamp to wait to replace 8 pairs of envelopes of resistance wire frame glue 13 to heat.
Use when of the present invention, at first will go up vacuum pump valve 51, descend vacuum pump valve 52 to close, to go up vacuum pump 61, descend vacuum pump 62 to be connected on snorkel 41, the following snorkel 42, open vacuum pump valve 51, following vacuum pump 52 then, be put on the resistance wire 8 LCDs is smooth, adjust the position of LCDs, resistance wire 8 is just overlapped on the position of envelope frame glue 13, will go up again on the colored filter substrate 11 that board 1 is pressed onto LCDs.Open vacuum pump valve 51, begin to inhale vacuum, last sucker 31 firmly is adsorbed on the colored filter substrate 11 of LCDs on the board 1, same sucker 32 at present firmly is adsorbed on down the TFT substrate 12 of LCDs on the board 2, the resistance wire switch 9 of closed resistance silk 8, the resistance wire 8 of heating make envelope frame glue 13 thawing of being heated.Off resistance silk switch 9 rotates upward board 1 by turning handle 10, and under the drive of last sucker 31, colored filter substrate 11 also rotates with last board 1.In the rotating process, the envelope frame glue 13 that connects colored filter substrate 11 and TFT substrate 12 is completely severed, and the part air enters between colored filter substrate 11 and the TFT substrate 12 along the hole that envelope frame glue 13 splits, mention board 1 by handle 10 again, colored filter substrate 11 is separated with TFT substrate 12.To go up the last vacuum pump valve 51 of board 1 and the following vacuum pump valve 52 of following board 2 again and be threaded to snorkel 41 respectively, descend snorkel 42 to communicate, take out colored filter substrate 11 and the TFT substrate 12 separated, analyze after the cleaning with atmosphere.
In the present embodiment, in order to make colored filter substrate and the TFT substrate that board and following board can better the immobile liquid crystal display screen, present embodiment is preferably gone up the scheme that board and following board adopt five suckers respectively, snorkel is connected with five suckers ringwise, and be connected on the line direction of five suckers, so that the conduction of sucker and snorkel is better.In fact, it will be appreciated by those skilled in the art that the quantity of sucker is not construed as limiting the invention, when the suction of sucker is enough to firmly absorption up and down during board, sucker can be for one or more.
In the above-described embodiments, can also last vacuum pump valve 51 near on a side of 41 mouthfuls of snorkels gas valve 71 is set, side 42 mouthfuls of following vacuum pump valve 52 close snorkels down is provided with gas valve 72 down, last gas valve 71 is used to connect or cut off the last snorkel 41 and the atmosphere of its both sides, and following gas valve 72 is used to connect or cut off the following snorkel 42 and the atmosphere of its both sides.Last vacuum pump valve 51 also can be set directly on the last vacuum pump 61, and following vacuum pump valve 52 also can be set directly on the following vacuum pump 62.
Referring to shown in Figure 3, be screen detaching device for LCD translation working sections figure of the present invention again, when 13 heating of 8 pairs of envelopes of resistance wire frame glue, after envelope frame glue 13 melts, also can be by board 1 in handle 10 translations, under the drive of last sucker 31, colored filter substrate 11 is along with the translation together of last board 1.In the process of translation, the envelope frame glue 13 that connects colored filter substrate 11 and TFT substrate 12 is completely severed.Thereby reach the purpose of separating color filters substrate 11 and TFT substrate 12.
In technique scheme, handle also can be arranged on down on the board, perhaps directly will go up board and/or down board link to each other with other mechanical hook-up, be provided for the power that board and following board relatively move by other mechanical hook-up.
The present invention is simple in structure, cost is low, can be efficient, and the labour-saving is torn screen open to LCDs, and then has improved success ratio of tearing screen open and the efficient of carrying out failure analysis.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of embodiment of the invention technical scheme.
