Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating device for separating a copper clad laminate molded via a press plate from the press plate during the production of the copper clad laminate.

[0002]

2. Description of the Related Art In the production of a copper clad laminate, a copper foil, an inner layer circuit board having inner layer circuits formed thereon and a prepreg are laminated to form a laminate, and a press plate is interposed between the laminates. A plurality of copper clad laminates are simultaneously formed by heating and pressing from the vertical direction. The plurality of laminated copper clad laminates are individually separated while peeling off the press plate, conveyed to the next step, and cut by a cutting device to be a product.

Conventionally, a suction conveyance device has been used as a method for separating a plurality of copper clad laminates laminated via a press plate from the press plate. That is, there is a method of alternately adsorbing the press plate and the copper-clad laminate in order from the upper side using this adsorption conveyance device and lifting and separating them upward, and adsorbing and conveying the copper-clad laminate and the press plate one by one. Has been adopted.

The use of this suction conveyance device is the simplest method for separating and conveying the copper-clad laminate and the press plate one by one, but the copper-clad laminate and the press plate are in close contact with each other. It may be adsorbed and transported to. For this reason, the separation state of the copper-clad laminate and the press plate is always checked, and in order to ensure the further separation, a separation assisting work is performed by manually pressing the copper-clad laminate and the press plate one by one. There is.

[0005]

When the copper-clad laminate is conveyed by the suction conveyer as described above, the press plate and the copper-clad laminate adhere to each other particularly in the case of a thin copper-clad laminate, which may cause separation abnormality or The copper-clad laminate often breaks or scratches. In order to resolve this, manual intervention to assist separation was necessary. The present invention has been made in view of the above circumstances, and an object thereof is to provide a press plate separating device that eliminates the manual intervention of the separation assist and eliminates the separation abnormality.

[0006]

According to the present invention, a copper clad laminate and a press plate are alternately laminated, and a press plate and a copper clad laminate are adsorbed in this order from above by an adsorbing and conveying means,
In a device that separates and conveys from the lower copper clad laminate or press plate, the shaft is provided slidably in the axial direction by a bearing device, and is provided at the tip of the shaft,
The present invention is characterized in that the press head is configured to press a side end of the copper-clad laminate and a spring provided on a shaft that biases the press head toward the side end of the copper-clad laminate is provided as a pressing unit.

The pressing means are preferably arranged so as to press two parallel side edges of the copper clad laminate.

[0008]

According to the present invention, the side edges of the copper-clad laminate are fixed at a constant pressure by the elastic force of the springs, and therefore the press plate and the copper-clad laminate are adsorbed and conveyed in this order without resorting to manual work. Can be reliably separated and conveyed one by one.

[0009]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a press plate separating device according to an embodiment.

In the figure, a plurality of copper clad laminates 2 and press plates 3 are alternately laminated on a laminate conveying plate 1. The copper-clad laminate 2 is formed by laminating a plurality of inner layer materials on which inner layer circuits are formed and prepregs. A copper foil is attached to the inner layer material, and a plurality of copper-clad laminates 2 are manufactured at the same time by pressing the copper foil from above via a press plate 3.

The copper clad laminate 2 thus formed is separated from the press plate 3 and the copper clad laminate 2 one by one by the adsorbing and conveying means 4 from above and conveyed to the next step.

The sucking and conveying means 4 is constructed by attaching a sucking tool 6 having a plurality of sucking disks 5 downward to a movable rod 8 of an elevating cylinder 7, and the elevating cylinder 7 is equipped with a mounting arm 9
Mounted on the guide rail 10
It is configured to be attached to a traveling member 11 that can travel along the direction. The traveling member 11 includes a motor and traveling wheels (both not shown), and can travel along the guide rail 10.

Pressing means 12 for pressing the parallel side edges 2a of the copper-clad laminate 2 are disposed on both sides of the copper-clad laminate 2. The pressing means 12 is fitted to the slide bearing 13, the shaft 14 supported by the slide bearing 13 so as to be movable forward in the axial direction, that is, the horizontal direction, the press head 15 provided at the tip of the shaft 14, and the shaft 14. Is inserted and one end is slide bearing 13
And a coil spring 16 locked to the press head 15 at the other end. The press head 15 is made of synthetic resin and has a cylindrical shape.

According to this embodiment, the shaft 14 is moved forward by the elastic force of the coil springs 16 of the two pressing means 12 arranged to face each other, and the press head 15 is moved to the side ends 2a, 2a of the copper clad laminate 2. Is pressed with an appropriate pressing force.

The side end 2a of the copper-clad laminate 2 has a slight flexibility, and by setting the spring force of the coil spring 16 appropriately, the copper-clad laminate 2 is completely fixed. However, when an upward separating force of a certain amount or more is applied to the copper clad laminate 2, the side end 2a of the copper clad laminate 2 slides on the pressing surface of the press head 15 and moves upward. It can be suppressed as much as possible.

Further, since the side end 3a of the press plate 3 is located inside the side end 2a of the copper clad laminate 2, the side end 3a of the press plate 3 cannot be pressed and fixed by the press head 15. Absent. Since the press head 15 is made of synthetic resin as described above and is not hard like metal, the copper clad laminate 2 is not damaged.

Therefore, as shown in FIG. 1, the elevating cylinder 7 of the adsorbing and conveying means 4 is extended, the upper surface of the press plate 3 is adsorbed by the adsorbing plate 5, and the elevating cylinder 7 is contracted again, whereby the press plate 3 can be reliably separated from the copper-clad laminate 2 on the lower side and conveyed.

When the upper surface of the copper clad laminate 2 is adsorbed and separated by the adsorption board 5, the pressing force applied by the press head 15
Since the upward separating force of the copper-clad laminate 2 by the suction plate 5 is larger, the side end 2a of the copper-clad laminate 2 has the press head 1
The pressing surface of 5 can be slid to move upward. At this time, since the press plate 3 located below the separated copper-clad laminate 2 is in close contact with the upper surface of the lower copper-clad laminate 2 in addition to its own weight, the copper separated upwards is separated. Laminated board 2
Never lifted with.

In this embodiment, the pressing means 12 are arranged to face each other, but at least one side is a fixed wall (not shown), and one pressing means 12 is used to fix the copper clad laminate 2 to the fixed wall. The copper clad laminate 2 can be fixed by pressing the other side end 2a.

[0020]

As described above, according to the present invention,
When the copper clad laminate is manufactured, the copper clad laminate and the press plate can be separated from each other without the need for assisting the separation of the copper clad laminate to press the copper clad laminate by manual intervention, and the separation abnormality can be eliminated.
