Next, the table horizontal moving part 142 is a component that horizontally moves the table forward and backward portions 144 and the suction table 120 coupled thereto as shown in FIGS. 1 and 2. Therefore, the table horizontal moving part 142 is formed to be long to include both a product supply position, a peeling position, and a product discharge position, and horizontally moves the table forward and backward parts and the suction table to the correct position at the correct time.

Next, the copper foil peeling recovery unit 150 is installed in the center front of the table driving means 140, as shown in FIGS. 1 to 3, and moved to the copper foil separation area by the table driving means 140. It is a component that peels off the protective copper foil 20 attached to the surface of the product 10 adsorbed on the adsorption table 120 and automatically recovers the peeled protective copper foil 20. That is, the copper foil peeling recovery unit 150 not only peels the protective copper foil 20 from the surface of the product 10, but also the adhesive tape 30 used in the peeling process of the protective copper foil 20 peeled in a continuous process. It is recovered without interrupting the process as it is adhered to.

To this end, in this embodiment, the copper foil peeling recovery unit 150 is specifically shown in FIGS. 2 and 3, the peeling head 151, the head up and down driving unit 152, the tape supply unit 153, and the tape recovery unit ( 154). First, the peeling head 151 is attached to the lower side by bonding the lower portion of the cut edge of the protective copper foil 20 on the surface of the product 10 adsorbed on the adsorption table 120 using an adhesive tape 30. It is a component that peels while moving. That is, the peeling head 151 is a component that actually performs a peeling operation in contact with the protective copper foil 20, specifically, as shown in Figure 3, the head body 155, the adhesive roller 156 and light oil It comprises a roller 157.

3, the head body 155 forms an overall shape of the peeling head 151, and is a component coupled to the head up and down driving unit 152 to drive up and down. And the adhesive roller 156 is installed at the front end of the adsorption table 120 of the lower surface of the head body 155 to rotate freely, the adhesive tape 30 supplied by the tape supply unit 153 is the outer surface It is a component that is wound on and adhered to the cut edge portion 20a of the protective copper foil 20 by advancement of the adsorption table 120.

That is, the adhesive roller 156 is installed to protrude than the front end of the head body 155, it is composed of a freely rotatable roller. And the adhesive roller 156, the adhesive tape 30 is wound so that the adhesive surface is facing outward, and the adhesive tape 30 is wound around the tape supply unit 153 and the tape recovery unit 154 to continuously You can move.

Next, the diesel roller 157 is installed on the opposite rear end of the adhesive roller 156 among the lower surfaces of the head body 155 to be freely rotatable, and the tape supply unit 153 ) Is a component that is wound on the outer surface of the adhesive tape 30 supplied by. That is, the light roller 157 is simply to allow the adhesive tape moved to the adhesive roller 156 to pass through, and is installed for the function of the tension maintaining roller 158 to be described later.

Next, as shown in FIG. 3, the head vertical drive unit 152 is installed vertically standing in combination with the side of the peeling head 151, and a component that moves the peeling head 151 in the vertical direction. to be. That is, the head up and down driving unit 152 moves the peeling head 151 up and down to the correct position at the correct time according to the control signal of the control unit.

Next, the tape supply unit 153 is a component that continuously supplies the adhesive tape 30 to the peeling head 151, as shown in FIG. 3, and the adhesive tape before the peeling operation is performed on the outer surface A certain amount is wound up. In addition, the tape recovery unit 154 is supplied by the tape supply unit 153, and is configured to continuously recover the adhesive tape 30 to which the protective copper foil 20 peeled by the peeling head 151 is attached. Element. That is, the tape recovery unit 154 is to recover together the peeled protective copper foil 20 adhered to the adhesive tape 30 by winding in the direction of recovering the adhesive tape 30 in a flattened state. .

By this recovery operation, it is possible to continuously recover the protective copper foil and there is no interruption of operation, so the efficiency of the process is increased.

On the other hand, as shown in FIGS. The tension maintaining roller 158 is installed between the adhesive roller 156 and the light oil roller 157, and the outer surface of the adhesive roller 156 and light oil roller 157 in the process of the peeling head 151 descending. It is to keep the tension constant by pulling the adhesive tape 30 wound on the lower side lower.

Thus, the adhesive tape 30 is not struck during the peeling process by the tension maintaining roller 158 to maintain a stretched state by maintaining a constant tension, and the protective copper foil 20 is recovered in a flattened state without being crushed. It becomes a condition that can be.

On the other hand, the protective copper foil separation device 100 according to the present embodiment is further provided with a control unit (not shown in the drawing). The control portion of the adhesive tape 30 is wound on the adhesive roller 156 is attached to the cut edge portion of the protective copper foil, while moving the head body 155 downward, maintaining the tension The roller 158 is lowered together to keep the tension of the adhesive tape 30 constant, and when the separation of the protective copper foil 20 is completed because the head main body 155 descends to the bottom, the tape recovery unit 154 ) Is rotated to recover the adhesive tape 30 together with the separated protective copper foil 20.

And in this embodiment, it is preferable that the head body 155 is further provided with a copper foil guide belt 159. The protective copper foil 20 that is attached to and peeled off from the adhesive tape has a very thin thickness and has a characteristic of folding back in a peeled state due to a property that one surface is attached to the product 10. Accordingly, as shown in FIGS. 1 and 10, a pair of copper foil guides installed side by side with the adhesive tape on both sides of the adhesive tape 30 wound around the adhesive roller 156 and the tape recovery part 154 Belt 159 is further provided.

The pair of copper foil guide belts 159 having such a structure is wound freely while being wound in a tensioned state on free rotating rollers installed at both ends of the upper and lower ends, and both ends of the protective copper foil 20 attached to the adhesive tape 30 are It is to guide the descent in a flat state without bending.

At this time, it is preferable that the surface of the copper foil guide belt 159 is made of a material having adhesive strength, because the protective copper foil 20 can be stably guided. That is, by fixing both ends of the hobo copper foil with adhesive force, it is possible to guide the both ends of the protective copper foil 20 until it is wound in a fixed state so as not to bend in any direction. Here, the adhesive force refers to a property of repeatedly attaching the protective copper foil as a physical property of the material itself, but leaving no foreign matter on the surface of the protective copper foil. Therefore, the copper foil guide belt 159 may be made of, for example, silicone rubber.

Next, as shown in FIG. 1, the product discharging unit 160 is installed adjacent to the table driving means 140 and receives a product attached to the adsorption table 120 to discharge the product to the outside. Element. The product discharging unit 160 is also made of a multi-joint robot so that the product 10 attached to the adsorption table 120 can be transferred to a discharge position and put down, and preferably has a product adsorption function.
