Fig. 12 is a block diagram of a rework method of a display part module according to an embodiment of the present invention, and fig. 13 is a schematic view of a correlation of a temperature adjusting part and an adhesive force of an adhesive part.
Referring to fig. 1, a rework apparatus 1 of a display part module according to one embodiment of the present invention includes a display part module 100, a temperature adjustment part 200, and a separation facilitating part 300.
The display part module 100 includes a display part 110 and a glass part 120 which are coupled by an adhesive part 130.
The display unit 110 may be exemplified by various types of devices that perform a display function, such as an LCD, a PDP, and the like. As with the FPD, the display unit 110 may be formed not only in a planar shape but also in a curved shape.
The description of the curved display unit 110 will be specifically described in the description of the rework apparatus 1 of the display unit module according to another embodiment.
The glass portion 120 is disposed to face the display portion 110. The bonding part 130 is disposed between the display part 110 and the glass part 120 such that the display part 110 and the glass part 120 are bonded to each other. At this time, the adhesive part 130 may be an optically transparent double-sided tape, an optically transparent adhesive, or the like.
The temperature adjustment unit 200 is provided with a display unit module 100, and can adjust the temperature within a set temperature range. The set temperature range indicates a temperature range in which the adhesive force of the adhesive portion 130 is reduced. At this time, when the temperature of the temperature adjustment portion 200 is set, the temperature range in which the adhesive force of the adhesive portion 130 is reduced is set, and the temperature range in which the display portion 110 and the glass portion 120 are not damaged is set.
In fig. 13, the adhesion force (gf/inch) represents the surface adhesion force of the adhesive part 130, i.e., the adhesive force. The temperature (. degree. C.) represents the temperature of the temperature adjusting section 200. As shown in fig. 13, when the adhesive force of the adhesive portion 130 decreases to F or less when the temperature of the temperature-adjusting portion 200 is maintained at T1 or T2 or more, the temperature of the temperature-adjusting portion 200 is maintained at a low temperature of T1 or less or at a high temperature of T2 or more, so that the adhesive force of the adhesive portion 130 can decrease to F or less. In other words, the temperature adjustment portion 200 is maintained at a low temperature or a high temperature so that the adhesive force of the adhesive portion 130 is reduced to F or less.
The separation facilitating part 300 facilitates the display part 110 and the glass part 120 so that the display part 110 and the glass part 120 are separated. The separation facilitating part 300 is interposed between the display part 110 and the glass part 120, and ejects a fluid to the adhesive part 130. At this time, the height of the end of the separation promoting portion 300 can be formed to be smaller than the interval between the display portion 110 and the glass portion 120. Therefore, when the separation promoting portion 300 is inserted between the display portion 110 and the glass portion 120, the separation promoting portion 300 can prevent the display portion 110 and the glass portion 120 from being damaged.
Further, the height of the end of the separation promoting portion 300 is the same as the interval between the display portion 110 and the glass portion 120, and the height of the discharge port (not shown) of the separation promoting portion 300 can be formed to be smaller than the interval between the display portion 110 and the glass portion 120. Therefore, the fluid ejected from the separation promoting portion 300 can be collectively ejected to the adhesion portion 130.
As shown in fig. 4, the separation promoting portion 300 is provided in plurality on the left and right sides (with reference to fig. 4) of the display portion 110, and can be inserted between the display portion 110 and the glass portion 120. At this time, the number and position of the separation facilitating parts 300 are not limited, and the number and position of the separation facilitating parts 300 may be changed within a range in which the separation facilitating parts 300 can be inserted between the display part 110 and the glass part 120, according to circumstances.
The temperature adjustment part 200 is provided with a mounting part 210, and the mounting part 210 allows the display part module 100 to be mounted. The mounting portion 210 fixes the display unit module 100, thereby preventing the display unit module 100 from moving sideways. As shown in fig. 2, the mounting part 210 is a groove part having a shape corresponding to the shape of the display part module 100 so that the display part module 100 is mounted and fixed.
The temperature adjustment part 200 further includes a first adsorption part 220. The first suction portion 220 is formed at the mounting portion 210 such that the mounting surface 100a of the display portion module 100 is sucked to the mounting portion 210.
Specifically, the first suction part 220 is connected to a pump (not shown) to vacuum-suck the mounting surface 100a of the display part module 100 mounted to the mounting part 210. As shown in fig. 9, the first suction part 220 can form a vacuum space between the mounting surface 100a of the display part module 100 and the mounting part 210 by a pump. Thereby, the display module 100 can be firmly fixed to the mounting portion 210. Thereby, the display part 110 and the glass part 120 can be easily separated.
The rework apparatus 1 of the display part module further includes a second adsorption part 400. The second suction part 400 sucks the opposite side surface 100b of the mounting surface 100a of the display module 100 so that one side of the display module 100 is separated from the mounting part 210.
As shown in fig. 4 and 6, the second suction unit 400 is disposed above the display unit module 100, and can vacuum-suck the display unit 110 of the display unit module 100. Thus, when the separation facilitating portion 300 ejects the fluid between the display portion 110 and the glass portion 120, and the display portion 110 and the glass portion 120 are separated from each other, the display portion 110 and the glass portion 120 can be easily separated from each other.
A rework apparatus of a display part module according to another embodiment of the present invention will be described below. At this time, the same contents as those of the other embodiment in one embodiment will be omitted from the description.
Referring to fig. 10 and 11, the display part module 100 of the rework apparatus 1 of the display part module according to another embodiment of the present invention may have a curved shape. In other words, the display unit 110 and the glass unit 120 have curved shapes. In this way, if the display unit module 100 has a curved shape, the temperature adjustment part 200 to which the display unit module 100 is mounted is also formed in a curved shape corresponding to the display unit module 100.
In this way, when the display module 100 has a curved shape, the separation promoting part 300 sprays the fluid to the display part 110 and the glass part 120 in a state where the adhesive force of the adhesive part 130 is reduced by the temperature adjusting part 200, so that the display part 10 and the glass part 120 are easily separated, and the recycling rate of the display module 100 can be improved.
A rework method of the display part module according to the present invention will be described below with reference to fig. 2 to 8. The reworking method of the display part module comprises the following steps: separating the display part 110 and the glass part 120 from the display part module 100 (S10), the display part module 100 including the display part 110 and the glass part 120 combined by the adhesive part 130; removing the adhesive portion 130 remaining on the display portion 110 and the glass portion 120 (S20); cleaning the display unit 110 and the glass unit 120 (S30); the display unit 110 and the glass unit 120 are mounted on the mounting unit 800 (S40).
The display part module 100 includes the display part 110 and the glass part 120 coupled by the adhesive part 130, and the step of separating the display part 110 and the glass part 120 from the display part module 100 (S10) includes the steps of: mounting the display module 100 to the temperature adjustment unit 200 (S11); setting the temperature of the temperature adjusting part 200 within a temperature range in which the adhesive force of the adhesive part 130 is reduced (S12); inserting the separation promoting part 300 between the display part 110 and the glass part 120 (S13); the separation facilitating portion 300 ejects the fluid between the display portion 110 and the glass portion 120, thereby separating the display portion 110 and the glass portion 120 (S14).
In the step of mounting the display module 100 to the temperature adjustment part 200(S11), the mounting surface 100a of the display module 100 is sucked by the first suction part 220 in a state where the display module 100 is mounted to the mounting part 210 of the temperature adjustment part 200 (see fig. 9). Accordingly, the display part module 100 can be fixed to the temperature adjustment part 200, so that the display part 110 and the glass part 120 can be easily separated when the display part 110 and the glass part 120 are separated.
In the step (S12) of setting the temperature adjustment part 200 within the temperature range in which the adhesive force of the adhesive part 130 is decreased, the temperature adjustment part 200 is set within the temperature range in which the adhesive force of the adhesive part 130 is decreased, and within the temperature range in which the display part 110 and the glass part 120 are not damaged.
In the step (S14) of separating the display part 110 and the glass part 120 by ejecting the fluid between the display part 110 and the glass part 120 by the separation promoting part 300, the opposite side surface 100b of the mounting surface 100a of the display part module 100 is sucked by the second suction part 400 in a state where the display part 110 and the glass part 120 are reduced in the adhesive force of the adhesive part 130 by the separation promoting part 300, so that one side of the display part module 100 is separated from the mounting part 210. This enables the display unit 110 and the glass unit 20 to be easily separated from each other.
In the step of removing the adhesive portion 130 remaining on the surfaces of the display portion 110 and the glass portion 120 (S20), the adhesive portion 130 remaining on the surfaces of the display portion 110 and the glass portion 120 is removed by a squeegee (scraper) 500. At this time, as shown in fig. 7, there is a difference in the manner of removing the adhesive portion 130 according to the set temperature state of the temperature adjustment portion 200. Here, the set temperature refers to a temperature set in a temperature range in which the adhesive force of the adhesive part 130 is reduced.
For example, when the temperature of the temperature adjusting unit 200 is T1 or less and the bonding portion 130 is in a low temperature state (see fig. 13), the suction unit 600 is operated together with the squeegee 500, so that the bonding portion 130 (see fig. 7 a) remaining on the surface of the display unit 110 or the glass unit 120 can be removed, and the suction unit 600 sucks the bonding portion 130 separated by the squeegee 500.
Although fig. 7(a) illustrates the suction unit 600 sucking the adhesive portion 130 remaining on the surface of the display unit 110 or the glass unit 120, the suction unit 600 is not limited to such an example, and the blower or the like may be changed as appropriate, and the adhesive portion 130 remaining on the surface of the display unit 110 or the glass unit 120 may be removed by blowing air to the adhesive portion 130 remaining on the surface of the display unit 110 or the glass unit 120.
On the contrary, when the temperature of the temperature adjusting section 200 is T2 or more and the bonding section 130 is in a high temperature state (see fig. 13), the bonding section 130 remaining on the surfaces of the display section 110 and the glass section 120 is removed by spraying the bonding removal liquid to the bonding section 130 remaining on the surfaces of the display section 110 and the glass section 120 through the spraying section 700 while using the squeegee 500 (see fig. 7 (b)).
Two types of processes for removing the adhesive part 130 remaining on the surface of the glass part 120 are shown in fig. 7, and the adhesive part 130 remaining on the surface of the display part 110 can be removed in the same manner.
In the step of mounting the display unit 110 and the glass unit 120 on the mounting unit 800(S40), the display unit 110 and the glass unit 120 that have been cleaned are individually mounted on the mounting unit 800. Specifically, the loading part 800 includes a first loading part 810 and a second loading part 820. The first loading part 810 is formed in a plate shape, thereby loading the display part 110. The second loading part 820 is formed in a plate shape, thereby loading the glass part 120. In other words, if the display part 110 and the glass part 120 are respectively washed, the first loading part 810 and the second loading part 820 separately load the display part 110 and the glass part 120, respectively (refer to fig. 8).
As described above, the display part 110 and the glass part 120 are separated from the display part module 100 by the rework method of the display part module according to the present invention, thereby minimizing damage of the display part module 100 and improving the recycling rate of the display part module.
While the invention has been described with reference to the embodiments shown in the drawings, it is to be understood that this is by way of example only and that various other modifications and equivalent arrangements may be devised by those skilled in the art based upon the teachings herein,
therefore, the true technical scope of the present invention should be determined by the scope of the claims.
