Description

  The present invention relates to an anisotropic conductive film sticking apparatus and a sticking method for sticking an anisotropic conductive film (ACF) to a substrate. More specifically, the present invention relates to an anisotropic conductive film pasting apparatus and a pasting method capable of pasting an anisotropic conductive film on a substrate such as a liquid crystal substrate or a control substrate in a single piece and automatically changing the anisotropic conductive film.

  Conventionally, only the anisotropic conductive film layer is half-cut to a predetermined length while leaving the roll-shaped anisotropic conductive film (ACF) separator, and the anisotropic conductive film layer formed into individual pieces is obtained. Affixing to electrode parts, such as a liquid crystal glass substrate and a control board, is performed.

  The anisotropic conductive film layer is made of an adhesive resin layer mixed with conductive particles in a tape shape on a separator to form an ACF, and is applied to an electrode terminal such as a liquid crystal glass substrate while heating. Thereafter, a TAB (tape automated bonding) component or the like is temporarily pressure-bonded to the electrode terminal via the anisotropic conductive film layer, and then finally pressure-bonded at around 200 ° C.

  The attachment of the ACF is continuously performed while separating the separator by pressing the half-cut ACF onto the liquid crystal glass substrate through a separator with a heated application roller and moving the application roller with respect to the liquid crystal substrate. (For example, patent document 1).

  In addition, the half-cut ACF is drawn on a heated glass substrate, and the separator is peeled off after the ACF is pressed against the glass substrate by horizontally moving in the attaching direction while pressing the application roller through the separator. It is made to peel by a mechanism (for example, patent document 2).

  Further, the ACF supply reel after the pasting operation is completed and used up must be replaced, and this ACF supply reel is automatically replaced (for example, Patent Document 3).

  In the above automatic replacement of the ACF supply reel, a reel mounting member on which at least two ACF supply reels can be mounted is provided so that it can be reversed, and when the ACF pasting operation is completed, the empty reel of the ACF is manually removed, A new ACF supply reel is mounted on the opposite side of the reel mounting portion, the reel mounting member is reversed, and the ACF chuck mechanism moves over the bonding path, and then the ACF is passed over the bonding path. Yes.

Japanese Patent No. 3045427 FIGS. 1 and 3 JP2007-324471 Japanese Patent No. 3852378

  By the way, since the ACF sticking device of Patent Document 1 is designed to stick the sticking roller while heating, the sticking roller is lifted away from the ACF separator each time one piece of ACF is stuck. In particular, when attaching an ACF (about 2 mm) narrow in the width direction, when the ACF separated from the application roller contacts the application roller again, a deviation occurs in the ACF travel path, and the application accuracy is improved. There is a problem that gets worse.

  In addition, as described above, the sticking roller separates from the ACF separator every time the ACF is stuck, so that the ACF sticking tension fluctuates, or the separator loosened when the sticking roller is separated from the separator is wound up. Therefore, there is a problem that the ACF supply tension and the ACF supply control in the attachment length direction are complicated. Furthermore, there is a problem that the pasting accuracy is deteriorated due to fluctuations in tension and variations in the pasting position.

  In addition, the ACF adhering device of Patent Document 2 is a device that horizontally moves the adhering roller instead of pressing with a predetermined length of the crimping tool to pressurize the ACF onto the glass substrate. Thereafter, the peeling roller acts to peel off the separator, and there is a problem that it takes time to peel off the separator and there is a problem that the apparatus is enlarged due to the necessity of mounting a peeling mechanism of the separator.

  In addition, since the sticking roller separates from the separator each time a piece of ACF is stuck, the ACF travel path is not stable as in the case of Patent Document 1, and the sticking accuracy is deteriorated. Since the separator is peeled off by the peeling roller from the ACF after application while applying tension, there is a problem that the ACF after application is pulled by the separator and peeled off.

  In addition, the exchange of the ACF supply reel in the ACF sticking apparatus of Patent Document 3 is designed to rotate and reverse the ACF sticking path, and the sticking position is stable because the sticking path of the ACF sticking apparatus is rotated. If the rotation accuracy is not increased, the pasting accuracy is deteriorated.

  Further, removal of used empty reels and installation of new reels are not automated, and there is a problem that it takes time for replacement work. In addition, since the tape chuck passes through the pasting path after the new reel is installed, the route for moving the tape chuck becomes complicated, the device becomes complicated, and replacement work is performed on the pasting path. During the replacement work, the apparatus must be stopped constantly, and there is a problem that the movable stop time of the apparatus becomes long.

  Accordingly, an object of the present invention is to improve the ACF attaching accuracy, reduce the size of the apparatus, reduce the attaching time, and automatically replace a used ACF reel with a new reel to reduce the working time. Is to provide.

In view of this, the invention of claim 1 is an application of an anisotropic conductive film that is bonded to a substrate by pressing an anisotropic conductive film composed of at least two layers of a separator and an anisotropic conductive film layer on a substrate while pressing with a sticking roller.

For ease of understanding, the thickness of the anisotropic conductive film layer 74, the separator 75, and the adhesive tape 35 is drawn exaggerated than the actual thickness.

  As shown in FIG. 9A, the substrate 10 is placed on the heating table 42, sucked and held by a suction mechanism (not shown), and conveyed while being heated by the heater 43 below the crimping unit 4. The ACF 9 is supplied from the supply reel 39 with the anisotropic conductive film layer 74 facing outside, and the cutter blades 33 and 33 and the pressing member 34 are horizontally moved by a predetermined amount in the direction of the arrow by an appropriate driving source (not shown), and the separator 75 is moved. Only the anisotropic conductive film layer 74 is cut at predetermined intervals, and the pressure-sensitive adhesive tape 35 is pressed against the anisotropic conductive film layer 74 by the pressing member 34.

  The supply of the ACF 9 is detected by an appropriate optical sensor (not shown) when the tip of the anisotropic conductive film layer 74 reaches below the sticking roller 23. When the leading end of the layer 74 reaches below the sticking roller 23, the supply of the ACF 9 is stopped.

  First, as shown in FIG. 9B, the anisotropic conductive film layer 74 half-cut at a predetermined interval by winding the adhesive tape 35 while retracting the cutter blades 33 and 33 and the pressing member 34 is applied to the adhesive tape 35.

  When the cartridge 11 is used as shown in FIG. 11A, it is detected by a suitable sensor (not shown) that the cartridge 11 is used, and the ACF sticking device 1 is stopped. The cutter blade 61 is applied to the position of the one-dot chain line on the left side of the pinch roller 73 to cut the separator 75.
