Hereinafter, the operation of the film loading apparatus according to an embodiment of the present invention configured as described above. For convenience of description, it is assumed that the first and second reel devices 200 and 300 first transfer the semiconductor film 201 to a porter (not shown) through the first reel device 200. In addition, the semiconductor film 301 to be provided by the second reel device 300 has its end drawn from the supply reel 310 for a predetermined period and passes through the idle roller 107b and the second feed roller 113 to the second standby unit. It is fixed to the holding part 421 of 420 in advance. In this case, the semiconductor film 301 is temporarily fixed by inserting the fixing protrusion 423 of the holding portion 421 into the buffer hole 302, and the tip is set in a state where the tip thereof protrudes to the bonding portion 441.

The semiconductor film 201 drawn out from the first reel device 200 is porter at a position coinciding with the transfer reference line L1 by the first transfer roller 111 moved to a predetermined position according to the driving of the driving cylinder 117. It is conveyed to the side (not shown). As such, when the semiconductor film exhaust signal is generated from a predetermined device (not shown) for detecting the exhaustion of the semiconductor film 201 during the transfer of the semiconductor film 201, the porting system is temporarily stopped in response to the semiconductor film exhaust signal. .

Subsequently, the feeding unit 470 operates to grip the semiconductor film 201 to which the first and second feeding rollers 471 and 481 are pre-transferred to a predetermined pressure. Thereafter, the second feeding roller 481 is rotated by a predetermined angle according to the driving of the driving motor 489 to transfer the semiconductor film 201 together with the first feeding roller 471 in the reverse direction of the transfer direction.

As described above, the sensor 492 is moved during the reverse transfer of the semiconductor film 201. Detects the buffer hole 202, it generates a cutting position detection signal.

The driving motor 489 stops driving according to the cutting position detecting signal, and then the cutting unit 450 cuts a part of the rear end of the semiconductor film 201 through the cutter 453. Thereafter, the driving motor 489 is driven again to correspond to the preset rotation angle to transfer the semiconductor film 201 to the bonding position.

After that, the driving motor 489 stops driving again, and the holding unit 421 moves the semiconductor film 301, which has been held in advance, to the working reference line L2. Accordingly, the front end of the pre-provisioned semiconductor film 201 and the front end of the semiconductor film 301 provided later are set at positions corresponding to the bonding portions 431 and 441.

In this state, the bonding portions 431 and 441 of the first and second bonding units 430 and 440 move toward the semiconductor films 201 and 301, and then attach the adhesive tapes to the semiconductor films 201 and 301 to complete the connection work through mutual bonding. do.

Subsequently, the holding unit 421 and the bonding units 431 and 441 move to their original positions, and the second transfer roller 113 moves to move the semiconductor film 301 to the transfer reference line L1. As the first and second feeding rollers 471 and 481 move to their original positions, the semiconductor film 201 held by the first and second feeding rollers 471 and 481 is converted into a transferable state. When the bonding operation is completed, the porting system is restarted.

As described above, the film loading apparatus according to an embodiment of the present invention can supply the film continuously without stopping intervals by automatically connecting the pre-providing film with the post-providing film automatically when the pre-provided film is exhausted.
