Description

Anisotropic conductive film removal system and control method thereof

technical field

The present invention relates to a system for removing anisotropic conductive film (Anisotropic ConductiveFilm; ACF) and its control method. Membrane removal system and control method thereof.

Background technique

Usually, various joining methods such as solder, TAB and COG are mainly used in the joining of electronic and electrical components. As a bonding method for display panels and driving components, methods such as soldering and ACF are mainly used.

Recently, the COG or TAB method, which has obvious advantages in terms of price and reliability, is widely used in the mounting of LCD drivers, and this package uses ACF, which is electrically and mechanically bonded to the LCD panel. In addition, as the size of the LCD increases and the resolution increases, the characteristics of the fine pitch (Fine Pitch) of the output terminal and a large number of technologies such as TAB-IC and COG are used in the installation process of the drive components in the panel. The process of ACF bonding has attracted more and more attention from the industry.

ACF is a coating paste that uses metal-coated plastic or metal particles to disperse conductive particles. Early ACF was applied to the bonding of dot matrix (Dot Matrix) LCD substrates and FPC (Flexible Printed Circuit), but recently It is mainly used in the output of TAB-IC.

In addition, when making a liquid crystal panel module, in order to load the image signal on the liquid crystal panel, it is necessary to package the integrated circuit (IC), and there are tape carrier packages (hereinafter referred to as Tape Carrier Package) containing lead (lead) on both sides. TCP). In a liquid crystal display device having a display panel and a driving circuit bonded by ACF, when a defect in the driver IC, a TCP defect, or a connection defect occurs, the operation is restarted. When restarting the work, the driver IC, TCP, and ACF are sequentially removed, and then new ACF is applied, and the driver IC or TCP bonded to the display panel is mounted through the above-mentioned ACF.

At this time, if ACF remains on the display panel, the combination of the remaining ACF and the newly applied ACF will cause stagnation between the metal lines on the panel, short circuits between lines, and pressure surface level differences. Therefore, it is necessary to clean all the remaining ACF on the display panel to avoid the problem of poor driving after re-operation.

For this reason, after external force is applied to the driver IC attached to the panel or substrate to remove it, a cleaning agent is applied to the panel or substrate with the driver IC attached, and a sharp metal knife similar to a metal knife is used for the remaining ACF on the substrate or panel. scrape off the above-mentioned ACF with a tool or by cutting out a substrate of the same material as the substrate in operation. Or, use inefficient, low-yield methods like toothbrushes or bamboo.

However, the above method will cause scratches (Scratch) on the panel and the substrate, so that the product is damaged in many places and it is difficult to reproduce.

In addition to the above physical methods of removal, there are also methods of removing ACF using chemical agents. However, there are many unsafe factors in the method of removing the ACF by immersing the liquid crystal panel attached with the ACF in a chemical formulation as a whole, depending on the chemical formulation. In particular, chemical agents may penetrate into other parts such as TCP, causing a new problem of damage to TCP; and depending on the proficiency of process operators, the production efficiency is also different, and there is also the problem that ACF is not easy to remove and prolongs the process time.

In particular, in order to remove ACF, a dipping method is currently mainly used. However, in the dip coating process, it is necessary to hold chemical agents in beakers or sinks, and exposure of such chemical agents to the air will endanger the health of workers and induce contamination or deterioration of parts other than those that need to be cleaned And other issues.

In addition, there is a remover (remover) used to remove ACF. Although it becomes sticky after a period of time, there is a limitation that the remover cannot be completely removed in the conventional cleaning process.

Recycle.

In addition, the above-mentioned input unit 10 to the discharge unit of the present invention all move the product K sequentially through the first conveyor belt 14 and the second conveyor belt 60. During this process, the position of the product K is determined by a plurality of image sensors (without Figures) confirm that the position detection and transmission-related control system of this type of product K can use the general technology in the field of automatic control, and further description of this part is omitted here. Next, each stage of the anisotropic conductive film removal system 1 used in the present invention from removal of the target product K to removal of ACF will be specifically described with reference to FIGS. 6 and 7 .

Preparation and investment stage

First, the ACF removal target product K is placed on the tray (Tray) 5 of the present invention, after the tray 5 is sent into the input unit 10, the preparation switch is activated, and then the power is turned on to start the operation. (S1) Next is the preparatory stage. After confirming whether the tray is normal, whether the air is normal, whether the cleaning agent (Chemical) is filled, and confirming the product model, the origin of each component of the coating part 30 and the cleaning part 70 is confirmed. (S2)

After entering the operation selection stage, after selecting automatic operation or manual operation mode through the touch screen, use the image sensor to confirm whether there is a product in the input part 10. When the input part 10 finds that there is the product K to be removed, it directly enters the next process, and when it finds that there is no product K to be removed, it enters the preparation state again. (S3～S4)

In order to put in the tray 5 containing the product K to be removed, the cartridge 12 is lowered and put in, and conveyed by the first conveyor belt 14 from the put-in position. (S5)

Coating stage

After the image sensor 5 confirms that the tray enters the position of the coating section 30 , the first conveyor belt 14 starts immediately to transport the tray 5 to the coating section 30 . As the tray 5 enters the coating section 30, the stopper 42b for stopping the tray rises to stop the tray 5, and at the same time, the stopper 42a for preventing re-insertion also rises thereupon to prevent the tray 5 from repeatedly entering the coating section 30. (S6～S7)

Afterwards, a coating process is performed, and a remover is applied to the product K to be removed on the tray 5 through the remover nozzle 32 in the applicator 30 . It should be noted that the above-mentioned remover nozzle 32 is preferably a needle-shaped tip (Tip), which can return to the original point after the coating operation is completed. In addition, the tray 5 can be put into the state of being placed in the placement fixture (Jig). The placement fixture referred to here is a set of 4 sets of special fixtures, which are manufactured in accordance with the transmission of automated equipment, and can be loaded sequentially, and 4 products K can be placed in a set of jigs (JIG) for loading at the same time, which can effectively shorten the loading time.

Regarding the technique of removing the anisotropic conductive film, the immersion (DIPPING) method for removing ACF is usually used. In the system 1 for removing ACF in the present invention, a needle-shaped (Tip) remover nozzle 32 is used in the coating stage. Coating can effectively avoid contamination of other components and effectively remove only ACF.

That is, in the above-mentioned coating stage, the ACF remover is applied to the area to be coated (ie, the TAB area where the TCP has been removed) through the remover nozzle 32 with a needle-shaped tip (Tip) having a specified thickness and width. (Remover) solution coating. (S8) It can be seen that the ACF remover is only applied to a specific area, and the contamination of other areas can be prevented by the ACF remover.

After the coating is completed, the remover nozzle 32 returns to the original point, the stopper 42b for stopping the tray descends, and at the same time, the first conveyor belt 14 starts automatically and enters the next process.

Expansion stage

While confirming the origin of the coating unit 30 , the coated tray 5 is transported to the buffer tray 52 where the expansion process is performed through the first conveyor belt 14 . (S9～S10)

After the above-mentioned buffer disk case 52 descends, the ACF will expand on the buffer disk case 52 within the set expansion time. (S11～S12)

One minute before the end of the expansion set time, the buffer disk box 52 rises to receive the next tray 5 , and the tray 5 after the expansion process is completed is transported to the next stage by the second conveyor belt 60 . (S13～S14)

cleaning stage

The cleaning stage is a process of transferring the expanded tray 5 to the cleaning part 70 through the second conveyor belt 60 and removing the ACF and the removing agent. Specifically, the cleaning phase is divided into two phases.

The first cleaning step is a step in which the viscous remover is removed at once by the primary cleaning part 72 after the expanded ACF is sent to the primary cleaning part 72 . (S15-S16) After the tray 5 enters the primary cleaning unit 72, the tray cover 80 for fixing the tray will descend to fix the tray 5, and the remover will be removed at one time by the automatic brush 78. (S17-S18) It can be seen that part of the ACF was removed in the first washing step.

As described above, after the ACF and the remover are removed at one time, the tray cover 80 for fixing the tray is raised, the second conveyor belt 60 is activated, and is conveyed to the secondary cleaning unit 85 . (S19～S20)

Similar to the above, after the transfer to the secondary cleaning section 85 is completed, it enters the secondary cleaning stage. The second cleaning stage is a stage for precisely removing ACF on the product K to be removed from which the remover has been removed in the first cleaning stage, and this stage consumes the longest time in the process. Accordingly, more cleaning liquid is sprayed in the two cleaning processes compared with the one cleaning process, so as to improve the cleaning effect.

The second cleaning stage is the same as the first cleaning stage. After the tray cover 94 for fixing the tray is lowered and the tray 5 is fixed, cleaning is performed by the automatic brush 92 . (S21-S22) It is recommended that the automatic brush 92 units be set as a set of 2 groups in the 1st and 2nd cleaning parts 72 and 85 respectively, so as to improve the stability of product quality.

As mentioned above, after the second cleaning is completed, the tray cover 94 rises, and the second conveyor belt 60 is started; the product K after cleaning is delivered to the discharge port. (S23～S25)

Afterwards, the empty tray 5 is retransmitted to the input unit 10 by the return conveyor 110, and the product K from which the ACF has been removed is collected separately.

From the above description, only the embodiments of the present invention have been described in detail, but there may be various changes and modifications within the technical scope of the present invention, and the above changes and modifications all belong to the scope of professional claims.
