DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for cutting cylindrical substrates, and more particularly, an improved method and apparatus for cutting cylindrical substrates into a predetermined number of printed original plates having a plurality of identical turns printed thereon with high precision. It is something to do KI@.

FIG. 1 shows a well-known printed circuit board manufacturing factory, in which a blank board 1G is glint printed and cut by sawing or other methods into a size that is suitable for printing, resulting in a blank board 12, and this small blank board 12.
The desired number of turns is printed on the print original plate 14.
is obtained.

This print original plate 14 has a plurality of enlarged identical turns,
Each section must be divided into 4 turns, but since the number of turns is too large for the press work that involves the usual final division, the print original plate 14 is placed on the shirring table for a predetermined number of turns before the press work. The printed small original board 1 is cut into
6 is made. and.

This printed small original board 16 is pressed into a desired shape by the above-described press processing to form a final printed circuit board 18.

In some cases, misalignment occurs between the printed circuit boards and the printed circuit board, which causes the problem of not being able to obtain the desired printed circuit board.

As is well known, when printing a print/main turn, the L print/arm turn 100 is often misaligned with respect to the print original plate 14, as shown in FIG. If there is a printing misalignment, or due to a cut-out angle error during cutting of the base plate 10 itself, the printed pattern 100 is significantly displaced in parallelism and other aspects with respect to the grating edge 14a of the print base plate 14. For this reason, there is a problem in that the peripheral edge 14 & of the original print plate 14 cannot be used as a cutting reference when cutting.

To solve the above-mentioned problem, the conventional cutting method is to drill holes corresponding to the glint no-turns in the print original plate and insert a bottle of the cutting device into the crest hole for positioning. Method 2 for drilling holes etc.
There are problems in that subsequent processing is required, resulting in poor workability and inability to obtain the desired cutting position accuracy.

It is characterized in that it feeds in parallel, and when a predetermined feed is completed, the printing original plate is pressed and fixed for cutting to perform the cutting action.

Furthermore, the present invention provides a printed circuit board cutting device that cuts a printed original board on which a plurality of identical or old turns have been printed into a predetermined number of pieces. a pair of parallelism sensors that respectively detect a pair of positioning marks provided on both left and right ends of the print original plate corresponding to printing/turning, and a pair of clamps based on the detection signal from the parallelism sensor.

Claims (1)

[Claims] (1) A printed circuit board cutting method for cutting a printed board on which a plurality of identical 9 turns are printed into a predetermined number of pieces,
A feed drive is applied to both ends of the cylinder original plate separately, and a pair of positioning marks provided at both ends of the print original plate are separately detected in correspondence with the cylinder head turn, and the printing original plate is moved based on the detection signal. The feeding amount at both ends of the cylinder is determined separately, the cylinder blank is fed to a predetermined cutting position with correct parallelism, and when the predetermined feeding is completed, the cutting action is performed by suppressing and fixing the cylinder blank for cutting. How to cut printed circuit boards. - (In a printed circuit board cutting device that cuts a printed original board printed with a plurality of identical/9 turns into a predetermined number of pieces, a pair of clamps that touch both sides of the cylinder original board and sandwich and feed the printed original board; A pair of parallelism sensors are provided at both left and right ends of the printed original plate in response to the arm turn, and a pair of parallelism sensors each detects the positioning angle. A printed circuit board cutting device comprising a pair of feed drive mechanisms that drive the feeds separately, and is capable of correctly positioning the cutting position of a printed original board in accordance with the rotation of the arm of the printer. (3) Patent Claims In the device described in range (2),
A printed circuit board cutting device (4) characterized in that the positioning mark is made of printed/mother-turn foil, and the glint pattern foil is also used as a circuit/turn. A printed circuit board cutting device characterized in that it consists of a 4-turn foil company print/mother turn foil, and a mother turn dedicated to positioning that is separate from the 4-turn foil company circuit turns. (1) The apparatus according to any one of claims (2), (3), and (4) is used to print a positioning mark on a print original plate corresponding to the relative movement locus of the parallelism sensor. A cylindrical board cutting device characterized in that no beneta other than the turn foil is provided. (6) Claims (2), (3), (4, (5))
The cylindrical substrate cutting device according to any one of the above, characterized in that when the glint original plate is fed, a pressing force is applied to the gripper against the printed original plate, and when the gripper returns, the clamp holder is released from the printed original plate. (7) Range of % allowance request (work, (3), (4), t5
), (6), wherein the cylindrical substrate cutting device is characterized in that when the gripper returns, the printed original plate is suppressed and fixed by a work holder.
