2. Description of the Related Art A laminated board for a printed wiring board, which is included in a resin board, for example, a prepreg body in which a metal foil is laminated as an outer layer is alternately sandwiched between molding plates, and an object to be pressured is sandwiched between heating plates and heated. Pressing molding methods have been adopted. According to this molding method, as a method of separating the resin plate and the molding plate and taking out the resin plate, a method of adsorbing the surface of the resin plate with an adsorption pad and lifting it is known. However, in the method of separating with the suction pad, the resin plate and the molding plate are strongly adhered to each other due to the molding pressure, so that the resin plate cannot be smoothly separated from the molding plate because it adheres to the resin plate and lifts the molding plate. There are drawbacks. Therefore, it is necessary to manually separate the resin plate and the molding plate from each other.

[0003]

However, it is very difficult and labor-intensive to manually separate the resin plate and the molding plate from each other. Therefore, a method for automatically and smoothly separating the resin plate and the molding plate is required. Is required.

The present invention has been made in view of the above facts, and an object of the present invention is to provide an automatic separating method for smoothly separating a resin plate that is in close contact with a molding plate from the molding plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method of the present invention will be described in detail below with reference to the drawings related to one embodiment.

1 to 3 are front views showing an example of a separating apparatus used for carrying out the method of the present invention, and FIG. 1 is a view showing a state where a resin plate is separated from a molding plate. 2 is a diagram showing a state before separation, and FIG. 3 is a diagram showing a state after separation.

The object to be separated from the molding plate 2 by the method of the present invention is the resin plate 1. An example of the resin plate 1 is a laminated plate in which a base material is impregnated with a thermosetting resin and semi-cured, and a prepreg is heated and pressed to cure the resin in the base material. The above-mentioned substrate is, for example, inorganic fibers such as glass and asbestos, organic synthetic fibers such as polyester, polyamide, polyvinyl alcohol and acrylic, woven cloth, non-woven cloth and mat made of natural fibers such as paper and cotton, and a combination thereof. Wood is used. As the thermosetting resin with which the above-mentioned base material is impregnated, a phenol resin, an epoxy resin, an unsaturated polyester resin, a melamine resin, a polyimide, a fluororesin or the like alone, a modified product, a mixture or the like is used. In the case of a printed wiring board included in a laminated board, a metal foil of copper, aluminum, iron, nickel, zinc or the like is superposed on these prepregs, and further, a metal foil is superposed and sandwiched alternately with the molding plate 2. As the molding plate 2, for example, a mirror plate having a rigidity higher than that of the printed wiring board and having a thickness of 1 to 5 mm, which is made of an individual material such as stainless steel or iron, or an alloy, is used. The heating and pressurizing conditions are appropriately determined depending on the type and composition of the thermosetting resin.
The laminated body 10 in which the resin plates 1 and the molding plates 2 are alternately stacked is in a state in which the resin plates 1 and the molding plates 2 are in close contact with each other by applying pressure. The resin plate 1 is separated from the molding plate 2.

An example of a separation device used to carry out the method of the present invention will be described. As shown in FIG. 2, the separating device has a movable shaft 5 that moves up and down, and a base 7 at the lower end of the movable shaft 5. An arm 4 which is freely displaced from a right angle to an acute angle about the pivot 8 with respect to the movable shaft 5 is pivotally attached to the base 7, and a suction pad 3 is provided on the lower surface of the arm 4. When the arm 4 is displaced at an acute angle with respect to the movable shaft 5 about the pivot axis 8, the resin plate 1 adsorbed on the adsorption pad 3 is curved in a downward convex shape. By freely displacing the arm 4 with respect to the movable shaft 5, the degree of the bowed warp of the adsorbed resin plate 1 is increased or decreased.

In the separating device, the resin plate 1 and the molding plate 2 are alternately stacked on both sides of the laminated body 10 so that both ends of the uppermost surface of the laminated body 10 are the molding plate 2 or the resin plate 1. A laser displacement meter 6 for detecting is provided. The laser displacement meter 6 irradiates the upper surface of the laminate 10 with a light beam having a predetermined wavelength at an acute angle, the light beam is reflected on the irradiation surface, and the irradiation surface is determined by the ratio of the reflected light beam returning to the direction of the laser displacement meter 6. It detects what it is. When a mirror plate is used as the molding plate 2, only a very small amount of the light beam irradiated to the mirror-molding plate 2 at an acute angle returns to the laser displacement meter 6. On the other hand, since the resin plate 1 and the resin plate 1 on which the metal foils are overlapped diffusely reflect, compared with the molding plate 2 of the mirror plate, a large amount of the irradiated light returns to the laser displacement meter 6.
Based on the ratio of the light rays reflected toward the laser displacement meter 6, it is detected whether the uppermost one of the laminated body 10 is the molding plate 2 or the resin plate 1.

The separating method of the present invention using the above separating apparatus will be described. As shown in FIG. 2, heat-press molded resin plates 1 and molded plates 2 are alternately combined. When the resin plate 1 is separated, the movable shaft 5 descends with the arm 4 at a right angle, the upper surface of the resin plate 1 is sucked by the suction pad 3, and then the arm 4 is displaced at an acute angle with respect to the movable shaft 5. The suction pad 3 is twisted inward, and the resin plate 1 is raised while being bent in an arc shape. It should be noted that the arm 4 has a movable shaft 5
On the other hand, it does not matter if the arm 4 is raised at a right angle without being displaced at an acute angle, but if the resin plate 1 is raised while being bent, the forming plate 2 will adhere to the resin plate 1 less frequently. preferable.

As shown in FIG. 1, the suction pad 3 has approximately 200
When it has risen by about mm, the laser displacement meter 6 detects whether the uppermost end of the laminate 10 is a molded plate or a resin plate.

As a result of the above detection, if it is detected that both ends of the uppermost surface of the laminated body 10 are the molding plates 2, it is judged that the molding plate 2 is loaded on the laminated body 10 without adhering to the resin plate 1. , The adsorbed resin plate 1 is taken out.

As a result of the detection, if it is detected that both ends of the uppermost surface of the laminated body 10 are the resin plates 1, it is determined that the molding plate 2 has adhered to the resin plate 1 and has risen, and the arm 4 is moved.
However, the angle is freely displaced with respect to the movable shaft 5. The arm 4 is freely displaced at an angle with respect to the movable shaft 5, so that the resin plate 1 having an arcuate shape is repeatedly twisted. When this twist is repeated, air enters from the ends of the resin plate 1 and the molding plate 2 and gradually separates from the ends,
The separated molding plate 2 falls on the laminated body 10. The above operation is performed by forming the molding plates 2 on both ends of the uppermost surface of the laminated body 10.
Is repeated until is detected. As shown in FIG. 3, after detecting that both ends of the uppermost surface of the laminate 10 have become the molding plates 2, the adsorbed resin plate 1 is taken out.

According to the method for automatically separating a resin plate according to the first aspect of the present invention, the resin plate that is in close contact with the molding plate can be automatically and smoothly separated from the molding plate.
