BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing jig and device for a hybrid integrated circuit, and more particularly to a board ear part separating jig for separating an ear part of a collective circuit board.

[0002]

2. Description of the Related Art Generally, when a hybrid integrated circuit board is manufactured by forming a wiring pattern on a circuit board and mounting circuit parts, as shown in FIG. 7, a plate-shaped ceramic or glass-epoxy resin is used. A collective circuit board (30) is manufactured in which dividing grooves (slits) 31, 32, 33, 34 each having a depth of about half the thickness are formed in the insulating plate in the vertical and horizontal directions. This assembly circuit board 30
Are divided by the dividing grooves 31, 32, 33, 34 into hybrid integrated circuit substrates 35, 35 ... And ears 36, 36. The integrated circuit board 30 is formed by cutting off the ears 36 along the dividing grooves 31 and 32 around the collective circuit substrate 30 and then dividing along the remaining dividing grooves 33 and 34. Substrate 35, 35
It is separated into ...

In order to break off the ears 36, 36 ... From the composite circuit board 30 for such a hybrid integrated circuit, the ears for dividing the substrate ears having a substantially "convex" shape as shown in FIG. The tool 40 was conventionally used. In this board edge splitting jig 40, the left and right side surface portions 41, 42 and the top surface portion 43 are provided with the ear portion insertion grooves 44, 4 respectively.
5 and 46 are provided. These ear insert grooves 44, 45, 4
6 has different widths so that it can be applied to three types of integrated circuit boards with different thicknesses. Further, the depth of the ear insertion grooves 44, 45, 46 of the illustrated board edge division jig 40 is the same, and no matter which of the ear insertion grooves 44, 45, 46 is used, the division folding is performed. The width of the ear can be the same.

When the edge portion 36 is divided and broken from the integrated circuit board 30 using the board edge dividing jig 40, for example, the following method is used. First, from among the ear portion insertion grooves 44, 45, 46 formed in the board ear portion dividing jig 40,
The one suitable for the thickness of the collective circuit board 30 is selected, and the ear portion 36 of the collective circuit board 30 to be broken is inserted therein.
Next, press the main body of the collective circuit board 30 with one hand,
The other hand holds the board edge dividing jig 40 and pushes down the collective circuit board 30 against the board edge dividing jig 40. As a result, the ear insertion grooves 44, 4 are placed at the positions of the dividing grooves 31.
Apply the edges of 5, 46 and concentrate the cutting force on the dividing groove 31,
The ear portion 36 is divided along the dividing groove 31.

[0005]

However, when an ear portion is to be separated from the integrated circuit board for a hybrid integrated circuit by using the above-described conventional ear portion dividing jig 40, the three end face portions of FIG. Among the ear insertion grooves 44, 45, 46, there is a phenomenon that the occurrence rate of burr is higher when divided using the grooves 45, 46 on both sides than when the center ear insertion groove 44 is used. To be found. In other words, a collective circuit board for a hybrid integrated circuit
When manually dividing the ear portion 36 from the portion 30, burrs are less likely to occur when the assembled circuit board 30 is set vertically. This is because when the conventional jig 40 is used by placing it on the table in the posture shown in FIG. 6, for example, when the collective circuit board 30 is inserted into the ear insertion grooves 45 and 46 on both sides, This is considered to be because the collective circuit board 30 inevitably becomes substantially horizontal, the distance from the table surface becomes extremely short, and it is difficult to divide the collective circuit board 30.

Therefore, according to the present invention, it is possible to divide the ears of the collective circuit board under almost the same conditions regardless of which ears insertion groove is used, and burrs are unlikely to occur regardless of which ears insertion groove is used. It is an object of the present invention to provide a jig for dividing a substrate edge.

[0007]

That is, in order to achieve the above object, according to the present invention, a plurality of projecting portions are radially projected about a central axis, and the central axis is provided on a concentric tip surface of the projecting portions. Provided is a jig for dividing a substrate ear portion, which is characterized in that ear insertion grooves are radially formed around the center. Further, there is provided a jig for dividing a substrate ear portion, wherein a rotary driving mechanism for applying a rotary driving force about a central axis is attached to the dividing jig.

[0008]

According to the above-mentioned jig for separating the substrate ears,
A plurality of protrusions are radially and symmetrically projected about the central axis, and ear insertion grooves are radially formed on the concentric tip end surface of the protrusions about the rotation axis. Therefore, when dividing the ears of the collective circuit boards of different thicknesses, when selecting the ears insertion groove that matches the thickness of the board, use the board ears dividing jig around the center axis. It can be rotated and selected. Then, no matter which ear insertion groove is selected, the ear of the collective circuit board can always be divided in the same posture. Therefore, since the ear portion of the collective circuit board can be divided in a posture that makes it easy to divide, the dividing force applied to the board is always in a desired state, and the occurrence rate of burrs is generally small and constant.
Further, according to the board ear splitting device having the rotation drive mechanism, the force applied to the collective circuit board when the ear part is separated from the collective circuit board is motorized and becomes constant, so that the labor of the splitting work can be saved. Is possible.

[0017]

As is apparent from the above description, according to the board ear part dividing jig of the present invention, even if the jig is rotated around the central axis to select the ear part inserting groove to be used, The insertion groove is always arranged at a constant position and at a constant angle. Moreover, since the jigs take substantially the same posture, when dividing the ear portions of the collective circuit board having different thicknesses or widths of the ear portions of the collective circuit board, the division work is the most easy to perform. Since it is possible to divide in this state, it is possible to reduce the occurrence of burrs in the dividing groove, and it is possible to perform a stable division operation of the substrate edge portion. Further, by providing a rotation driving mechanism in such a board edge dividing jig, it becomes possible to save labor for dividing the tabs of the collective circuit board.
