Description

Double-roller belt punching and conveying system and its transfer device

The invention relates to an assembling equipment of a flexible circuit board on a liquid crystal panel, in particular to a double-roll tape punching and conveying system and a transfer device thereof.

A general flexible circuit board assembly operation is to bond a flexible circuit board to a substrate (such as a printed circuit board, a liquid crystal panel, or an organic light emitting display panel) through an anisotropic conductive film (ACF) to make the flexible circuit The pins of the board and the outer pins of the substrate form an electrical connection. For details, refer to an assembly device for a flat display module disclosed in Taiwan Patent Publication No. 201237975, which uses a conventional double-roll tape cutting and conveying system. As detailed below.

FIG. 9 is a schematic top plan view showing a conventional double-roll tape cutting and conveying system 900. As shown in the figure, the conventional dual-roll tape cutting and conveying system 900 generally includes a pair of two-roll tape conveying mechanisms 90, two die-cutting devices 91, two transfer devices 94, and a ride-sharing device 95. The belt conveying mechanism 90 is responsible for continuously conveying a material belt 92 to the corresponding punching device 91. A common tape 92 is a COF tape using a Chip On Film (COF) package or a TCP tape using a Tape Carrier Package (TCP). As shown in FIG. 10, each die-cutting device 91 is responsible for die-cutting the tape 92, and each time a die-cut is performed, a piece of flexible circuit board 921 is die-cut from the tape 92. The specific structures of the aforementioned tape conveying mechanism 90 and the punching device 91 can be found in Taiwan Publication No. 200916290, which will not be described in detail.

Referring to FIGS. 9 and 10, the flexible circuit boards 921 punched from the two side-by-side die-cutting devices 91 are respectively received and transported by the two side-by-side transfer devices 94. Each transfer device 94 includes a heading track 941, a slider 942 movable along the heading track 941, and a suction head 940 provided on the slider 942 and capable of lifting and lowering. Each suction head 940 is located below the corresponding punching device 91. The flexible circuit board 921 punched from each punching device 91 is sucked by the suction head 940, as shown in FIG. 11. In addition, FIG. 10 further shows the situation when the suction head 940 is raised to a receiving position and sucks the bottom surface of one of the flexible circuit boards 921 in a vacuum suction manner. After each suction head 940 picks up a piece of flexible circuit board 921, it moves to the shared rider device 95 along the heading track 941 by the slider 942. The ride-sharing device 95 includes a lateral rail 951, a slider 952 movable along the lateral rail 951, and a suction head 950 disposed on the slider 952 and facing downward.

Please refer to the dashed part on the right side of FIG. 10, which shows that the suction head 940 of a transfer device 94 is located directly below the suction head 950 of the sharing device 95, and rises to a transfer position, so that the soft circuit can be sucked. The board 921 is close to the suction head 950 of the sharing device 95. At this time, the suction head 950 of the sharing device 95 can suck the top surface of the flexible circuit board 921 released by the suction head 940 from the transfer device 94, as shown in FIG. Show. Next, the suction head 950 of the ride-on device 95 moves along the lateral rail 951 by the slider 952 to directly above the suction head 940 of the other transfer device 94, and sucks another piece of the flexible circuit board 921 released by the suction head 940. On the top surface, a total of two flexible circuit boards 921 were drawn at this time, as shown in FIG. 13. Subsequently, the ride-hailing device 95 then delivers the two flexible circuit boards 921 to a delivery device (not shown) and transports them back for cleaning, gluing, false pressing, and local pressure operations, which are not described in detail.

Generally speaking, one of the reel-to-reel conveying mechanisms 90 and the corresponding punching device 91 of the conventional dual-reel-to-reel punching and conveying system 900 is used to punch out a source-side flexible circuit board 921 for soldering to The source edge of the panel, and another tape conveying mechanism 90 and the corresponding punching device 91 are used to punch out a gate edge flexible circuit board 921 for soldering to the gate edge of the panel. In other words, the two tape conveying mechanisms 90 mentioned above respectively convey two kinds of tapes 92 to punch out two kinds of flexible circuit boards 921 for soldering to the source side and the gate side of the panel, respectively. However, in some specific operations, for example, when it is necessary to solder multiple flexible circuit boards to the source side of a panel, and then solder multiple flexible circuit boards to the gate side of the panel (or the process is reversed), Still using the above-mentioned conventional double-roll tape cutting and conveying system would seem very inefficient.

For example, the system must first punch out a piece of flexible circuit board 921 on the source side by a blanking device 91 on the source side, and cut a piece of flexible circuit board 921 on the source side by the corresponding transfer device 94. The flexible circuit board 921 on the source side is fed back to the sharing device 95. After the transfer device 94 returns to the original position, the blanking device 91 on the source side punches out the next flexible circuit board 921 on the source side. Then, the transfer device 94 sends it to the sharing device 95, so that the sharing device 95 continuously receives the two flexible circuit boards 921 on the source side, and then transfers them together to the delivery device for delivery. During this period, the tape-side tape conveying mechanism 90 and its corresponding punching device 91 and transfer device 94 are suspended. After the source side of the panel finishes soldering of all source-side flexible circuit boards 921, The panel is rotated 90 degrees, and the tape conveying mechanism 90 at the gate side and its corresponding another punching device 91 and another transfer device 94 start to operate as described above, and are used to continue from the gate edge to the tape 92 The two flexible circuit boards 921 at the gate edge are punched out successively, and they are delivered to the ride-sharing device 95 in two passes, and then the ride-through device 95 transfers them to the delivery device for delivery.

As described above, whether the source-side reel 92 or the gate-side reel 92 is successively punched out of two flexible circuit boards 921, the corresponding transfer device 94 is divided into two passes. They are delivered to the ride-hailing device 95, and then they are transferred to the delivery device for evacuating together. The whole process takes time and is not efficient.

In view of the inefficiency of the conventional double-rolled tape cutting and conveying system in the prior art, the present invention proposes a double-rolled tape cutting and conveying system with an improved transfer device to greatly improve efficiency.

The head is moved up and down, so that the two suction heads successively suck the two flexible circuit boards punched out continuously by any punching device. The computer control system is used to control the two punching devices and the transfer device to perform punching and conveying operations. While one of the punching devices participates in the execution of the punching and conveying operations, the other punching device is suspended. Each time the punching device and transfer device perform the punching and conveying operation, any punching device performs two consecutive punching operations to punch out two flexible circuit boards.
