まりが非常に低いという問題があつた。 Ceramic substrates used as insulating substrates for ICs, LSIs, and other electrical components are usually formed using a doctor blade method or a rolling method. It was made by cutting a ceramic sheet (see FIG. 1), which was obtained by cutting grooves and then firing them, into a large number of small pieces by shearing them along the grooves. In the past, this division work was done by directly breaking by hand or using a hand punch, etc., which resulted in problems such as poor division, easy breakage, and unusable products, resulting in very low yields. .

ミツク板に適用し得るものではなかつた。 On the other hand, a glass plate is made by making multiple score lines on the surface of the glass plate in either the horizontal or vertical direction, and transporting it on a belt conveyor while passing through a roll gap with an arbitrary curvature. A device was developed in 1973 to automatically divide the material into many strips by curving it and applying shear stress along the cut line.
This device is disclosed in Japanese Utility Model Publication No. 30049 and Japanese Utility Model Publication No. 52-13333, and is well known, but it is intended for dividing a glass plate having a score line in one direction, and it can be divided either vertically or horizontally. The method can only be divided in one direction, and therefore, when dividing a ceramic sheet with dividing grooves in the form of a parallel lattice, which is the subject of the invention, it has the disadvantage that it must be divided into two parts. While the glass plate is placed on the belt conveyor and transferred to the dividing rollers, there is a risk that the glass plate may shift or move diagonally due to the vibration or rocking of the drive motor, which may impair the dividing accuracy. The glass plate dividing apparatus having the present invention could not be applied to ceramic plates for electronic components, which require high precision, such as the present invention described below.

れる。 According to the apparatus of the present invention, when the ceramic sheet 6 is fed from the chute 11 with the surface with the dividing grooves 6a and 6b facing upward, the ceramic sheet 6 is immediately attached to the first and second endless belts 4 and 5. Because it is held in the gap t between the facing surfaces of the feed-side sliding band, it is reliably transferred in the direction of the arrow in its held state without being displaced or diagonally fluctuated due to vibration or rocking by the drive motor. During this transfer process, firstly, the ceramic sheet 6 is fed between the concave roller 7a and the convex roller 7b of the curved roller 7, as shown in FIG.
As shown in Fig. 3, the ceramic sheet is curved in the same direction as the conveying direction, and therefore, among the parallel grid-like dividing grooves carved on the surface of the ceramic sheet, shear stress is applied along the horizontal dividing grooves 6a. disconnected. Next, this divided sheet is transferred to the presser roller 8 of the three rollers.
a, 8b and the receiving roller 8c, it becomes curved in the direction perpendicular to the conveying direction, as shown in FIG. Cut due to stress. These curved rollers 7 and three rollers 8
A large number of ceramic pieces 6c, which have been continuously divided into horizontal and vertical dividing grooves, are stored in a container 13 through a chute 12 and transferred to the next process.

Further, the front and rear stages of the curved roller and the three rollers may be reversed. Furthermore, although not shown in the drawings, by arranging the convex roller of the curved roller and the receiving roller of the three rollers so that they can move up and down, excessive shearing stress on the ceramic sheet can be prevented and a constant stress can always be applied. be.
