Description

Tape Carrier Package Transfer and Blanking Control System

The present invention relates to a tape carrier package conveyance and blanking control system, and more particularly to a tape carrier package conveyance and blanking control system for detecting the position of a film tape of a tape carrier package (TCP) to control conveyance and blanking. It is about.

1 shows an example of a tape carrier package as a plan view, and FIG. 2 shows a schematic process diagram for blanking the TCP 10 from a protective cover TCP film tape in which a plurality of tape carrier packages are arranged in a line.

In FIG. 1, the TCP 10 is used as a thin film micro-mirror array actuated (TMA) 1 or a driving IC chip of an LCD. In FIG. 1, an IC chip 11 is formed at the center of the film 12. And a pad portion 14 for electrical connection from the IC chip 11 to an external device, and at the end of the other device via an anisotropic conductive film by tape automated bonding (TAB). A pad portion 14 having a plurality of lead portions 14 'exposed to be mounted thereon is formed. The TCP 10 configured as described above is manufactured so that a plurality of TCPs 10 are arranged in a line in a shape of a TCP film tape F that is long in one direction during manufacture (see FIG. 4), as shown in FIG. 2. TCP 10 is blanked from each roll of the TCP film tape F, and is mounted in another element. This blanking process should be made precisely because the lead portion 14 'of the TCP 10 is densely formed, and for this purpose, the transfer of the TCP film tape F must also be made precisely.

In FIG. 2, the protective cover TCP film tape FC is mounted on the supply reel 20 in the form of a roll and is supplied from the supply reel 20 while the protective cover C is peeled off and wound on the protective cover winding reel 21. The TCP film tape F is guided in the direction to be conveyed to the blanking device 25 by the guide roller 22, and then the correct pitch P is shown by the lower feed roller 23 and the upper feed roller 24. As shown in Fig. 4, the TCP film tape F is supplied to the blanking device 25 and blanked so that the correct blank TCP 10 is dropped onto the tray 26 disposed below and loaded or transferred to the next process. This enables precise mounting with other devices. After blanking as described above, the scrap film is wound around the scrap film winding reel 27 through the scrap film guide roller 27 'and removed.

Therefore, the upper and lower feed rollers 23 and 24 are controlled by the servo motor 23 'for precise feeding so that the TCP film tape F is fed by the correct pitch.

However, since the TCP film tape F is a very thin film, a slight slip occurs even when driven by the servomotor 40 by a conventional roller, and thus, precise conveyance becomes difficult.

Accordingly, an object of the present invention is to provide a tape carrier package transfer and blanking control system for detecting, precisely conveying, and blanking a position of a TCP film tape.

A protective cover part TCP film tape F, in which 10 is arranged in a line, is shown as a plan view, and in FIG. 5, an example of a tape carrier package transfer and blanking control system according to an embodiment of the present invention is shown as a block diagram. .

In FIG. 3, the TCP 10 is disposed on the TCP film tape F at a TCP pitch P, and a plurality of transfer holes H are disposed along the length of the plurality of transfer holes H at both ends in the width direction of the TCP film tape F. (P '). At the beginning and the end of the TCP film tape F, the film portions before and after the center transfer hole C1 at the beginning and the end of the TCP film tape F are formed to be transparent. In addition, the film portion from the center transfer hole C1 to the transfer hole H before it is formed transparently.

5, the control system of the present invention receives a pulse capable of calculating the position signal or the position of the TCP film tape F from the detection sensor S, and receives the lower feed roller 23 of FIG. ) Is controlled to drive the feed roller drive servomotor 23 'so as to be driven by a predetermined rotation angle, and then the position of the TCP 10 is separated from the center of the lower feed roller 23 by a distance L. It controls to operate the blanking apparatus 25 in which a blanking center is located. Conventional sensors may be used as long as the detection sensor S generates a pulse between the opaque portion of the TCP film tape F and the transfer hole H, which is a transparent portion or a through hole.

The lower feed roller 23 has a pair of conveying sprockets, the conveying sprockets being inserted into each of the conveying holes H of the TCP film tapes F, respectively, as they rotate. In order to precisely convey, a plurality of transfer values 23 "are formed at the pitch angle θ of the circumferential pitch at the circumferential surface 23 'of the diameter D corresponding to the pitch P'. Is formed along

The blanking device 25 is installed such that the blanking center of the TCP 10 is located at a position spaced apart by the distance L from the center of the lower feed roller 23.

The detection sensor S is arranged between the lower feed roller 23 and the blanking device 25 at the position of the distance L 'from the blanking device 25 in Fig. 3 to the TCP film tape F. By generating a pulse signal that distinguishes the transparent portion before the transfer hole H and the center transfer hole C1 from the non-transparent portion to detect the presence or absence of (10), the TCP (10) on the TCP film tape (F) The position is input to the controller 50.

By forming in this way, the center conveyance hole C1 is detected along the conveyance hole H at the time of conveyance of the TCP film tape F. As shown in FIG. That is, when the pulses of the detection sensor S are continuous, the center position of the TCP 10 can be calculated by subtracting 1/2 of the length of the transfer hole H from the end of the pulse.

With this configuration, the controller 50 detects the presence or absence of the TCP 10 from the detection sensor S to the TCP film tape F, and transfers the TCP film tape F precisely by the TCP pitch P. And a pulse corresponding to the rotation angle of the feed roller drive servomotor 23 'to be blanked at the correct position, and output the operation signal so that the blanking device 25 is operated after the feed is stopped. Usually, the blanking device 25 is performed by the upper and lower molds 25 'and 25 "on the press, in which case the upper mold 25" of the press is outputted once by outputting a reciprocating signal to the controller of the press once. Will be lowered and raised.

In this way, the TCP 10 can be blanked at the correct position of the TCP film tape F. Accordingly, the IC chip 11 is attached and attached to the peripheral end (pad part) through the pattern part 13. The TCP 10 in which the lead 14 'of the IC chip 11 is formed can be accurately mounted.

In the drive servomotor 23 'for the rotation of the lower feed roller 23, 1 with respect to the pitch angle θ of the feed value 23 "of the lower feed roller 23 and the diameter D of the circumferential surface. When rotating at an angle of θ1 per pulse, the initial position S of the TCP 10 is detected by the detection sensor S while transferring the start portion S of the TCP film tape F for the initial setting. By outputting a pulse corresponding to a value of (360 × L ′) / (2πD × θ × θ1) from one time, the center of the first TCP 10 is located at the center of the blanking device 25. In this case, It is easier to control the value of (360 × L ′) / (2πD × θ × θ1) to be a natural number.

On the other hand, when the detection sensor S detects the end of the TCP film tape F (shown as E in FIG. 3) so that the TCP 10 at the end is located at the center of the blanking device 25. It is controlled similarly to the above by detecting the boundary line B of the transparent part adjacent to the end.

In addition, the control unit 50 determines that the film portion before the center transfer hole C1 is made transparent so that the pulse of the detection sensor S is continuous, and 1/2 of the length of the transfer hole H from the end of the pulse is determined. The subtracted position may be calculated as the center position of the TCP 10.

This is preferred. In Figure 3 24 is a separation prevention upper feed roller.

For example, when the pitch P 'of the transfer hole H is 4.75 mm and the diameter D of the circumferential surface 23' of the sprocket is 60.48 mm, the pitch of the transfer value 23 "is given. When the angle θ is 9 degrees, the same pitch can be obtained in consideration of the thickness up to the center of the TCP film tape F. The distance L 'is set to (N × 4.75) mm and the drive servomotor 23 If ') rotates 0.0072 degrees per pulse, the initial setting is possible by detecting the first TCP 10 in the detection sensor S and outputting a pulse of a value of (9 × N) /0.0072.
