Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dividing device for dividing a ceramic substrate having dividing grooves formed on the surface in the form of an S-shaped grid by breaking the ceramic substrate from the dividing grooves.

Ceramic substrates used as insulating substrates for ICs or electrical components are usually formed by forming vertical and horizontal dividing grooves on the surface of a ceramic green plate using the doctor blade method or rolling method, and then forming It is made by bending the resulting ceramic substrate along dividing grooves and dividing it into predetermined unit pieces.

However, such division can be done by cutting directly by hand,
Or, it is divided by band punching, etc., but in either case, good division is not achieved, a considerable proportion of defects occur, the product cannot be used, and the yield is extremely low. There is a need for a dedicated dividing tool for this purpose.

The present invention has been made in view of the above points, and will be explained below based on the drawings of the embodiments.

Reference numeral 1 denotes a low narrow protrusion protruding from the upper edge of the front end of the base 2, and on the front end side 17 of the base 2 which has the protrusion 1 and is long in the front-rear direction, The holding piece 3 is horizontally installed so as to have a required gap 4 between it and the upper surface of the base 2.

Reference numeral 5 denotes a mounting base that projects higher than the base 2 on the other side 18 of the front end of the base 2, and on the mounting base 5, an upper piece 7 of a stopper 6 having a downwardly angled shape is mounted. A screw 9 is screwed onto the mounting base 5 through an elongated hole 8 in the longitudinal direction drilled in the upper piece 7, thereby fixing the upper piece 7 so as to be adjustable in longitudinal movement.

Thus, the lower end of the bundle 11 having the pusher (roller in the illustrated example) 10 is placed on the front end side 17 of the base 2, and the peripheral surface of the pusher (roller) 10 is placed on the front end of the base 2. Upper edge ridge 1
is pivotally connected via a pivot shaft 12 so as to pass above.

The present invention consists of the above-mentioned structure, and in order to break and divide a ceramic substrate having vertical and horizontal dividing grooves on its surface, first, loosen the screws 9 screwed into the mounting base 5.
The distance between the back surface of the downwardly angled hanging piece 13 of the stopper 6 and the front end of the substrate 2 corresponds to the ceramic substrate 1 to be broken.
After setting the upper piece 7 of the stopper fitting 6 to the same position as the spacing between the horizontal dividing grooves 15, 16, and 16 in the vertical and horizontal dividing grooves 15, 16, and 16 in the mounting base 5 with the screw 9, Fixed to.

After that, while inserting the ceramic substrate 14 having the same width as the width of the base 2 into the gap 4 between the presser piece 3 on the front end side 17 of the base 2, the front end of the ceramic substrate 14 is pressed against the stopper. After contacting the back side of the hanging piece 13 of the metal fitting 6, when the bundle 11 in the upright state is tilted forward around the pivot 12,
When the pusher (roller) 10 on the inside of the bundle 11 passes directly above the protrusion 1 on the upper edge of the front end of the base 2, it presses downward the upper surface of the ceramic substrate 14 protruding from the front end of the base 2, and presses the ceramic substrate 14 downward. 14 is cut from the horizontal dividing groove 16.

Moreover, the low narrow protrusion 1 on the upper edge of the front end of the base 2 is located directly below the horizontal dividing groove 16 in the ceramic substrate 14 to be broken, so that the ceramic substrate 14 is cut in the horizontal dividing groove 16. When the ceramic substrate 14 is broken off by the pusher (roller) 10, stress is concentrated on the dividing groove 16 due to the action of a lever.
It is reliably broken from this horizontal dividing groove 16 and no damage occurs.

The divided pieces of the elongated ceramic substrate 14 that have been cut from the horizontal dividing grooves 16 are then broken into unit pieces from the vertical dividing grooves 15 with your fingers to obtain a ceramic substrate of the required size. Obtainable.

As described above, the present invention has a simple structure and has excellent practicality in that a ceramic substrate can be easily and reliably broken into a predetermined width without chipping from the dividing groove.

so that the breaking force applied to the ceramic base piece 14 by the pusher (roller) 10 is concentrated only in the vicinity of one end of the dividing groove 16 of the ceramic base piece 14;
It is assumed that the pusher (roller) has a length of about 10 (7) t.

That is, as shown in FIGS. 3 and 4, the pusher (roller)
10 is arranged near one side 17 of the base 2 where the presser piece 3 is located, and the breaking force by the pusher (roller) 10 is applied to a point near one end of the dividing groove 16 of the ceramic base piece 14. By doing so, cutting of the ceramic base piece 14 along the dividing grooves 16 can be performed most accurately.

This was confirmed by the results of experiments conducted by the present inventor.
