Abstract

PROBLEM TO BE SOLVED: To more efficiently perform the work of separating the surface layer material of a sheet-like multilayer base material by moving a separating claw toward the surface layer material of the multilayer base material in a state of the tip of the separating claw abutting on the end surface of the multilayer base material. SOLUTION: A working unit 22 is energized to the mounting side of a separating claw 1 by the elastic force of an elastic body 26, whereby the end surface of a multilayer base material 2 is pressed by the tip of the separating claw 1. At this time, the separating claw 1 is elastically deformed by its own spring elasticity. A pressure rising cylinder 17 is actuated in this state to raise the working unit 22. When it reaches above the multilayer base material 2, the separating claw 1 is released from the drag from the multilayer base material 2 and moved toward the tip side by the elastic force, and its elastic deformation is solved. According to this, the surface layer of the multilayer base material 2 is flicked by the tip of the separating claw 2, and the end part of the surface layer material is separated. In the after treatment, the whole surface layer material is separated.

As the sheet-like multilayer base material 2, a circuit-forming metal foil 34 is disposed on one surface of a resin sheet such as a prepreg containing a thermosetting resin and the like, and a molding metal foil such as an aluminum alloy foil is disposed on the other surface. A primary molded substrate 33 obtained by disposing the foil 35 and molding by heating can be used. Here, as a method of molding the primary molded substrate 33, for example, a resin sheet,
A long metal foil 34 for forming a circuit and a long metal foil 35 for forming are used, and they are laminated while continuously feeding them to form a laminate, and heat molding is performed while further sending the laminate continuously. A continuous method can be adopted. Hereinafter, a method for peeling the surface layer material 2a such as the forming metal foil 35 from the sheet-like multilayer base material 2 such as the primary formed substrate 33 will be described.

The surface material 2 from which the multilayer substrate 2 is to be peeled off on the upper surface
a is disposed between the product upper presser plate 29 and the product lower presser plate 30, and the lower clamp cylinder 32 is operated to dispose the product at a desired height on the upper surface of the product lower presser plate 30 and the upper clamp. Activate the cylinder 31 and press the product holding plate 2
9 is moved toward the product holding plate 30, and the multilayer base material 2 is sandwiched between the product holding plate 29 and the product holding plate 30.
On the other hand, the angle adjusting arm 20 is turned around the turning shaft 21 to adjust the angle of the claw portion 1a of the peeling claw 1 with the multilayer base material 2. Next, the rotating handle 12 is rotated to adjust the height position of the peeling claw 1 so that the tip of the claw portion 1 a of the peeling claw 1 is arranged at the same height as the height of the end face of the multilayer base material 2. I do. In this state, the forward cylinder 13a is operated to advance the slide unit 15, and accordingly, the peeling claw 1 is brought close to the end surface of the multilayer base material 2.
3b is operated to finely adjust the position of the slide unit 15, and as shown in FIG.
The position of the peeling claw 1 in the horizontal direction is adjusted so as to press the end surface of the peeling claw. At this time, the working unit 22 slides along the slide guide 20a toward the side opposite to the side where the peeling claw 1 is attached due to the drag force from the multilayer base material 2, and the elastic body 26 expands due to this, and the elastic force causes the elastic body 26 to expand. The working unit 22 is urged toward the attachment side of the peeling claw 1, and presses the end surface of the multilayer base material 2 with the tip of the claw portion 1 a of the peeling claw 1. Also, the peeling claw 1 is elastically deformed and curved by its own spring elasticity. In this state, the lifting cylinder 17 is operated to raise the working unit 22. At this time, the tip of the claw portion 1a of the peeling claw 1 moves upward while pressing the end face of the multilayer base material 2, and when it reaches above the end face of the multilayer base material 2, the drag from the multilayer base material 2 Is released, the elastic body 26 moves toward the distal end by the elastic force, and the elastic deformation of the peeling claw 1 is eliminated. Along with that,
The surface material 2a of the surface layer of the multilayer base material 2 is the claw portion 1a of the peeling claw 1.
And the end of the surface material 2a is peeled off.
Next, the upper clamp cylinder 31 is operated to operate the product upper holding plate 2.
9 is lifted and the multilayer substrate 2 is removed from the substrate clamp 28.

The multilayer base material 2 from which the end portions of the surface layer material 2a have been peeled off is intended to peel off the entire surface layer material 2a in a later step. At this time, at the end of the multilayer substrate 2,
The entire surface layer material 2a can be peeled by pulling the portion where the surface layer material 2a has been peeled off by human power or the like. Also, the lower surface of the peeling jig having the adhesive material formed on the lower surface is pressed onto the upper surface of the peeling lower portion at the end of the surface layer material 2a and bonded, and in this state, the jig is slightly raised, By moving horizontally toward the inside of the multilayer base material 2, the entire surface layer material 2a can be peeled off. Here, by using a peeling device that automatically controls the operation of the peeling jig, the work of peeling all the surface material 2a can be automatically performed.

Here, when the above-mentioned primary molding substrate 33 is used as the sheet-like multilayer base material 2, a single-sided metal foil-clad laminate can be obtained by peeling off the molding metal foil 35 as the surface material 2a. The single-sided metal foil-clad laminate can be used for manufacturing a printed wiring board.

When the end of the surface material 2a is peeled from the sheet-like multilayer substrate 2 as described above, when the multilayer substrate 2 is thin, the tip of the peeling claw 1 is attached to the multilayer substrate 2. It may be difficult to contact the end face. In such a case, when adjusting the height of the tip of the peeling claw 1 by operating the rotary handle 12, the tip of the peeling claw 1 is arranged below the multilayer base material 2, and the forward cylinder 13a and the slow-speed forward cylinder When the horizontal position adjustment of the peeling claw 1 is performed by operating 13b, the tip of the peeling claw 1 is adjusted so as to protrude into the inside of the multilayer base 2 by 2 to 3 mm from the end surface of the multilayer base 2 (FIG. 9). When the lifting cylinder 17 is raised in this state, first, the upper surface of the claw 1a, which is the tip of the peeling claw 1, comes into contact with the lower part of the end of the multilayer base material 2, and the working unit 22 is moved as the peeling claw 1 rises. The sliding nail 1 rises while sliding on the lower part of the end of the multilayer base material 2,
Eventually, the tip of the peeling claw 1 comes into contact with the end face of the multilayer base material 2. When the peeling claw 1 further rises in such a state, the end of the peeling claw 1 comes into contact with the end surface of the multilayer base material 2 in the same manner as described above, and thereafter the surface material 2a is formed by the same operation as in the above case. The end can be peeled off.

Further, in the above-described embodiment, the peeling nail 1 is formed in a plate shape. In this case, the width of the portion where the peeling nail 1 and the end face of the multilayer base material 2 come into contact with each other is increased, and the surface layer is formed. The width of the exfoliated portion at the end of the material 2a can be increased, and the subsequent operation of pulling the exfoliated end of the surface material 2a to exfoliate the entire surface material 2a can be easily performed. Further, the shape of the peeling claw 1 is not limited to such a plate-like shape, and various shapes can be appropriately used.

FIG. 6 shows another example of the shape of the peeling claw 1. In this case, the peeling nail 1 is
The plurality of claw members 3 each having a needle-like tip are arranged in parallel. And the surface material 2 from the multilayer substrate 2
In peeling off the end of a, the tips of the plurality of claw members 3 are arranged so as to be aligned along the end surface of the multilayer base material 2,
When the tips of the peeling claws 1 are brought into contact with the end faces of the multilayer base material 2, the tips of the plurality of claw members 3 are brought into contact with the end faces of the multilayer base material 2 at the same time. By doing so, the total area of the portion where the peeling nail 1 and the end face of the multilayer base material 2 come into contact with each other is reduced, and the pressing force of the peeling nail 1 against the end face of the multilayer base material 2 can be increased. It is possible to improve the reliability of the operation of peeling off the end of the surface material 2a at the tip of the first member 1.

In peeling off the edge of the surface material 2a from the sheet-like multilayer substrate 2 as described above,
When adjusting the angle of the nail portion 1a of the peeling nail 1 with the multilayer base material 2, as shown in FIG. 8B, the nail portion 1a is disposed so that the tip side faces diagonally downward, and the nail portion 1a is formed. It is preferable that the angle between the substrate and the multilayer substrate 2 is in the range of 30 ° to 80 °. That is, the peeling claw 1 is arranged at an angle of 30 to 80 ° with respect to the multilayer substrate 2 so that the tip of the claw portion 1a of the peeling claw 1 faces the opposite side to the moving direction of the peeling claw 1 when performing the peeling operation. Then, in this state, the tip of the claw portion 1a is
And the peeling nail 1 is brought into contact with the surface material 2a of the multilayer base material 2.
It is moved toward the side. This way,
When the tip of the peeling claw 1 is moved while being in contact with the end face of the multilayer base material 2, the movement can be smoothly performed, and the bouncing of the peeling claw 1 can be suppressed. In addition, since a drag in a diagonal direction is applied to the peeling nail 1 from the multilayer base material 2, the peeling nail 1 elastically deforms in a direction opposite to the moving direction, and when the elastic deformation of the peeling nail 1 is eliminated, the peeling nail 1 Surface material 2a
Will be played strongly toward the outside. Therefore, it is possible to prevent the peeling claw 1 from jumping and to reliably peel off the end of the surface layer material 2a to peel off. The angle formed between the claw portion 1a and the multilayer base material 2 is particularly preferably 40 ° to 45 °. Also, as described above, the peeling nail 1
When the claw portion 1a, which is the tip portion, is formed by bending the claw portion 1a in the direction opposite to the moving direction with respect to the multilayer base material 2, the arrangement angle of the peeling claw 1 with respect to the multilayer base material 2 can be easily adjusted. is there. Here, using the peeling nail 1 in which the angle between the claw portion 1a and the supporting portion 1b is 160 °, the angle between the claw portion 1a and the multilayer base material 2 is set to be in the range of 40 ° to 45 °, and the surface layer is formed. When the end of the material 2a is peeled, the angle adjusting arm 20 is rotated to adjust the angle of the claw portion 1a of the peeling claw 1 with the multilayer base material 2, as shown in FIG. The inclination angle γ of the unit 22 from the horizontal plane is set to 20 ° to 25 °.

In the above-described embodiment, the movement of the peeling claw 1 in a state in which the peeling claw 1 is in contact with the end surface of the multilayer base material 2 is performed by vertical movement of the lifting / lowering cylinder 17. The method of moving the peeling claw 1 is not limited to such a method, and various methods can be appropriately adopted, for example, by employing the working unit 22 as shown in FIG. . The working unit 22 shown in FIG. 8 has a rotating shaft 3 in a substantially horizontal direction that is substantially perpendicular to the sliding direction of the sliding unit 15.
The working unit 22 is formed as a rotating wheel that can be driven to rotate. A plurality of peeling claws 1 are provided on the outer peripheral surface of the working unit 22 so as to protrude outward over the entire circumference. Using a peeling device provided with such a working unit 22 at the lower end of the angle adjusting arm 20, the multilayer substrate 2
In peeling off the end portion of the surface material 2a, first, the working unit 22 is removed in the same manner as in the above-described embodiment.
The state is such that the tip of one of the peeling claws 1 provided in the above-mentioned manner is in contact with the end face of the multilayer base material 2 or the tip is arranged below the end of the multilayer base material 2. In this state, when the working unit 22 is rotationally driven so that the peeling claw 1 arranged on the multilayer base material 2 side starts to move upward, the plurality of peeling claws 1 sequentially come into contact with the end surface of the multilayer base material 2. The peeling operation can be performed a plurality of times at the same place on the end face of the multilayer base material 2 at a time. In this way, even if it is difficult to peel off the edge of the surface material 2a by one peeling operation, the edge of the surface material 2a is reliably peeled by a plurality of peeling operations. Is what you can do.
