[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.
