Hereinafter, an example of the principle of operation of the press working apparatus 100 having the above-described structure will be described.

In the state where the moving unit 20 is spaced apart from the fixing unit 10, the working tapes T2 and T3 and the first tape T1 are separated from each other by a predetermined length Lt; / RTI > That is, the workpieces T2 and T3 move 40 mm for 0.1 second, and the first tape T1 moves 100 mm for 0.1 second.

The moving part 20 is lowered to the fixing part 10 and pressed for 0.1 second when the working tapes T2 and T3 and the first tape T1 are simultaneously stopped for 0.1 second, 2 tape (T2) and the upper surface of the first tape (T1) are attached to each other.

8, when the moving part 20 is lifted up and separated from the fixing part 10, the to-be-processed tapes T2 and T3 having the plurality of through holes H formed thereon, Only the final workpiece S having a predetermined shape remains on the upper surface of the first tape T1.

The final workpiece T2 thus processed can be attached to an image panel such as an LED panel or an OLED panel of a portable communication device such as a smart phone.

The press working apparatus 100 having the above-described structure is provided with the fixed portion 10 and the movable portion 20 which reciprocates up and down with respect to the fixed portion 10, A press working apparatus for pressing a sheet member (T) advancing between a first portion (20) and a second portion (20) in a predetermined shape, the sheet member (T) comprising a first tape (T1) And a second tape (T2) to which the first tape (T1) can be attached and which moves the first tape (T1) between the fixing portion (10) and the moving portion A feeder 30; The second tape T2 is transported from the fixing portion 10 to the moving portion 20 at a second feeding speed V2 in a state in which the second tape T2 is not attached to the first tape T1, 2 feeder 40 and the second tape T2 and the first tape T1 are attached to each other when the moving part 20 is lowered to the fixing part 10 and press- The distance L2 between the through holes H is smaller than that in the conventional press working apparatus 1 in which the three tapes T1, T2 and T3 are jointed and fed together at the same speed, It is possible to reduce the amount of loss of the processed tapes T2 and T3 to be disposed of.

The press working apparatus 100 further includes an unwinder (not shown) which uncovers the second tape T2 stored in the form of a roll and feeds the second tape T2 to the inlet 13 between the fixing portion 10 and the moving portion 20 50); And a winder 60 for winding the second tape T2 coming out from the outlet 14 between the fixing part 10 and the moving part 20 in the form of a roll. , T3) can be easily supplied and recovered.

Since the second feeder 40, the unwinder 50, and the winder 60 are reciprocally moved in a state where they are coupled to the moving unit 20, It is possible to easily implement a structure for separating and transferring the workpieces T2 and T3 at a second conveyance speed V2 while being separated from the first tape T1 conveyed at the first conveyance speed V1 There are advantages. In particular, there is an advantage that it is very easy to manufacture the press working apparatus 100 by modifying the conventional press working apparatus 1.

The press working apparatus 100 has a through hole H formed in the work tapes T2 and T3 because the second feed speed V2 is smaller than the first feed speed V1. (L2) between the final workpiece (S) disposed on the first tape (T1) can be made smaller than the interval (L1) between the final workpiece (S) disposed on the first tape (T1) There is an advantage that the amount of loss of the processed tapes T2 and T3 to be disposed of can be adjusted.

The press working apparatus 100 is a carrier tape in which the first tape T 1 is attached to the second tape T 2 to transfer the second tape T 2, The second tape T2 is disposed on the upper surface of the first tape T1 so that only the second tape T2 is pressed and the first tape T1 is press- Has the advantage of being reusable.

In this embodiment, the second feeder 40, the unwinder 50, and the winder 60 are reciprocally moved in a state of being coupled to the moving unit 20, It is needless to say that at least one of the feeder 40, the unwinder 50 and the winder 60 may not be coupled to the moving part 20. [
