Problems solved by technology

Therefore, when the ACF layer of the ACF tape or the adhesive material layer of the adhesive tape is to be bonded to each other by pressing the tapes with the required connection strength, those adhesive materials or adhesive materials are likely to be exposed. When transporting, there is a problem that it is prone to failure
[0016] In addition, in connection methods using adhesive tapes of other components, it is necessary to arrange an adhesive tape supply mechanism, which complicates the structure of the device, and also requires management of the adhesive tape independently of the ACF tape. Problems that lead to increased burden
In addition, in the method of connecting using an adhesive tape or a double-sided adhesive tape attached to a reel, etc., automatic connection is not possible, and the adhesive surface deteriorates during the management of the reel, making it difficult to ensure the required connection strength.
[0017] In addition, as shown in Patent Document 2, in the method of connecting the connecting tapes by heat welding using the connecting tape, it is necessary to use a special ACF tape with connecting tapes bonded at both ends thereof as the ACF tape, and therefore the cost becomes lower. high, and cause problems with no versatility

no. 1 approach

[0073] First, an ACF applying device as an example of the adhesive tape applying device according to the first embodiment of the present invention will be described with reference to FIGS. 1 , 2 , 3 , 4A, 4B, and 4C.

[0074] In Fig. 1 and Fig. 2, the ACF attaching device 1 of the present embodiment includes: a positioning device 3 for supporting the substrate 2 to move and position it; a lower support table 4 for supporting the side end of the substrate 2 from below; A crimping device 6 that presses the ACF tape 5 to be attached to the substrate 2; a tape supply device 7 that supplies the ACF tape 5; Tape peeling device 8; tape recovery device 9 for recovering the release tape of the peeled ACF tape 5. 10 is a transfer device for transferring the substrate 2 sent to the feeding position of the ACF attaching device 1 to the positioning device 3 . In FIG. 1 , 1A is a control device that controls the overall operation of the ACF sticking device 1 .

[0075] As shown in FIG. 2,...

no. 2 approach

[0090] Next, an adhesive tape sticking device according to a second embodiment of the present invention will be described with reference to FIGS. 5 to 13 . In addition, the same reference numerals are assigned to the same constituent elements as those of the above-mentioned first embodiment, description thereof will be omitted, and differences will be mainly described.

[0091] This embodiment is mainly different from the first embodiment in the structure of the tape supply device 7 and the tape recovery device 9, which can automatically connect the end portion 5E of the first ACF tape 5a and the start end portion 5S of the second ACF tape 5b, thereby continuously The ACF belt 5 is supplied ground.

[0092] In FIG. 5 , the tape supply device 7 is provided with a tape connecting device 31 for connecting the end portion 5E of the first ACF tape 5a and the start end portion 5S of the second ACF tape 5b, and a reel supply device 32 for sequentially supplying the reels 13. The tap...

Abstract

An adhesive tape application device has a stage (25) on which the tail end (5E) of a first tape member and the head end (5S) of a second tape member are placed in an overlapped manner, an ultrasonic tool (26) having projections arranged on its surface making contact with the head end (5S) or the tail end (5E) of the overlapped tape members, an ultrasonic vibration generation device (27) for applying ultrasonic vibration (28) in the tape thickness direction to the ultrasonic tool (26), and a pressing device for applying to the ultrasonic tool (26) a pressing force directed to the stage (25). The construction allows the tail end (5E) of the first tape member being used and the head end (5S) of the second tape member paid out from a new reel to be connected to each other by a simple and low cost structure in a condition where there is no possibility of trouble of tape feeding.

Description

technical field [0001] The present invention relates to an adhesive tape applying device for attaching an adhesive tape for fixing mounting components to a substrate such as a display panel typified by a liquid crystal panel or a PDP (Plasma Display Panel). Moreover, in such an adhesive tape sticking apparatus, it is related with the tape connection method which connects and adds the end part of the tape member to which the adhesive tape continuous in the longitudinal direction was stuck. Background technique [0002] As a method of mounting components on a substrate such as a display panel represented by a liquid crystal panel or a PDP (Plasma Display Panel), it is known that an ACF (Anisotropic Conductive Film) as an example of a tape component is placed on a substrate. One example of the adhesive tape in the ) tape is ACF, which is pressed against the substrate, then the release tape is peeled off, the ACF layer is attached to the substrate, and TCP (Tape Carrier Package)...
