BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TAB tape transfer apparatus having an improved structure of a transfer roller having an IC chip protection structure in a transfer path of a TAB tape (tape automated bonding tape).

[0002]

2. Description of the Related Art In a TAB tape transport apparatus, as shown in FIG. 4, several rollers are used in a TAB tape transport path. Then, like the tension roller 1 in FIG.
There are cases that are located on the side.

The TAB tape transport roller 1 used in such a case has a convex portion corresponding to the thickness of the IC chip 3 on both peripheral surfaces of the roller body 4 as shown in FIG. A tape-shaped portion was formed to form the tape transport surface 5, and the concave portion inside the tape transport surface 5 was formed as a chip retracting concave portion 14.

However, even if the transport roller 1 has such a structure for protecting the IC chip 3, when the TAB tape 2 having a wider tape width is used, when the TAB tape 2 is applied and tension is applied. In addition, as shown in FIG. 6, the central portion of the TAB tape 2 bends, and the IC chip 3 contacts the body 4 of the roller, so that the IC chip 3 may be damaged.

Therefore, it is conceivable to prevent the TAB tape 2 from being bent by providing a tape supporting surface 7 having substantially the same height as the tape conveying surface on the roller body 4 which is the bottom surface of the IC chip retracting recess 14. The position of the IC chip 3 in the TAB tape is not always the same, and it is desired to develop a TAB tape transport device using the roller 1 that can change the position of the tape supporting surface 7 in accordance with the position of the IC chip 3. I was

[Problems to be solved by the invention] The present invention is provided with the following points as solutions. Forming a tape support surface by fitting a tape support ring into an IC chip retreating recess where no IC chip is located. The tape support surface can be moved to a desired position by sliding the tape support ring.

[0007]

Means for Solving the Problems The present invention is to solve the problems According to the process 30, the tape conveying surface convex on both sides the circumferential surface of the roll body portions are formed, the roll body portion between the tape conveying surface is concave A transport roller in which a tape support ring having an outer peripheral surface substantially at the same height as the tape transport surface is mounted on the roller body of the TAB tape transport roller serving as a retracting portion so as to be slidably fixed in the roller axis direction. Provided is a TAB tape transport device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a TAB tape transport roller used in the present invention will be described below. FIG. 1 is a cross-sectional view of a TAB tape transport roller 1 used in the present invention.
Is a roller body. On both sides of the roller body 4, convex tape conveying surfaces 5, 6 having a height sufficient to retract the IC chip 3 are formed. As a result, the portion that is one step lower between the tape transport surfaces 5 and 6 is used as the chip retracting recess 14.

One tape transport surface 5 is formed integrally with the end of the roller body 4 as a convex thick part as shown in the lower part of the figure, while the other tape transport surface 6 is formed as a roller body. It is formed by a separate conveying surface forming ring 15 attached to the part 4. The convex portions outside the tape transport surfaces 5 and 6 are roller flanges 9 and 12 is the transport surface forming ring 1.
5 is a fixing screw.

FIG. 2 is a front view of the TAB tape transport roller 1. A tape support ring 8 having a tape support surface 7 whose outer peripheral surface is substantially the same height as the tape transport surface 5 is provided on the roller body 4. It is mounted so as to be slidably fixed in the roller axis direction (indicated by the arrow in the figure).

That is, a desired number of sliding grooves 10 are formed in the roller shaft direction of the roller body 4, and a number of sliding grooves corresponding to the number of sliding grooves 10 are formed on the inner peripheral surface of the tape support ring 8. A moving projection (not shown) is formed, and the sliding projection engages with the sliding groove 10 to slide. In addition, 11 in the figure
Is a fixing screw for the tape support ring.

The TAB tape transport roller 1 used in the present invention slides a sliding projection inside the tape support ring 8 from the roller body 4 on the side where the transport surface forming ring 15 is removed. The tape support ring 8 is fitted to the roller body 4 so as to match the movement groove 10. Tape support ring 8
Is fixed by a fixing screw 11 at an appropriate position according to the position of the IC chip 3 on the TAB tape 2.

Thereafter, the transfer surface forming ring 15 is fitted to the end of the roller body 4 having no tape transfer surface 5, and is fixed with a fixing screw 12. TAB with different IC chip positions
When the operation is performed with the tape 2 replaced, the fixing screw 11 of the tape supporting ring 8 is loosened, the tape supporting ring 8 is slid and moved to a predetermined position, and the fixing screw 11 is tightened again to fix the tape supporting ring 8. .

[0014]

The TAB tape transport roller according to the present invention is such that the tape support surface 7 is positioned by the tape support ring 8 on the roller body 4 where the IC chip 3 is not positioned as described above. Even when tension is applied to the roller 1, the TAB tape transport device can prevent the IC chip 3 from contacting the transport roller 1 without causing the deflection of the TAB tape 2.

Further, even when the TAB tape 2 having a different mounting position of the IC chip 3 is used, the tape supporting surface 7 can be positioned at an appropriate position by sliding only the tape supporting ring 8, which is versatile. It became.
