Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate (a substrate before mounting chips), an MCM (multi-chip module), a multi-layer substrate, a substrate substrate (hybrid substrate), a rectangular substrate from a material substrate such as a chip component. The present invention relates to a cutting device for obtaining a plate material (piece).

2. Description of the Related Art A cutting device for cutting a plurality of rectangular rectangular plate materials (pieces) modularized from a flat work such as a ceramic green sheet is provided with a vertical flat blade and a horizontal flat blade arranged adjacent to each other. A machine body supporting the mechanism and a work feeding mechanism for horizontally moving the work from the front to just below the cutting mechanism are provided. In this cutting device, the work feeding mechanism feeds the work placed on the table directly below the vertical and horizontal flat blades to stop it, and lowers it while moving the vertical flat blades to a predetermined pitch to move the work in the X direction. Cut in parallel, then rotate the cutting device itself 90 degrees, this time while cutting the horizontal flat blade parallel to the Y direction while moving the horizontal flat blade to a predetermined pitch, and then move the work feed mechanism back to return the table to the initial state. When dust is removed, the dust is removed and the plate (piece) is taken out.

[0003]

In such a cutting device, since the cutting device is rotated, not only the cutting time for the rotation time is lost, but also the feeding movement into the body and the returning movement from the body. There is a problem that the cutting efficiency is poor because it is wastefully consumed as a time dedicated to sending back and returning, which is not involved in the cutting time. Further, since the vertical flat blade and the horizontal flat blade are in close relation to each other, replacement work is dangerous and troublesome.

The present invention has been made in view of the conventional circumstances, and its object is to feed a workpiece into the machine body,
An object of the present invention is to provide an electronic component cutting device capable of obtaining a plurality of rectangular rectangular plate materials (pieces) modularized from a base substrate while moving a work in one direction without performing a returning motion.

[Means for Solving the Problems] Technical means taken to achieve the above-mentioned object are as follows: Claim 1 is a work feed mechanism for horizontally moving a work table, and a horizontal front-rear direction so as to cross the work feed mechanism. It is configured to be movable, and a horizontal cutting mechanism that can move up and down that cuts the work that is fed by the work feeding mechanism and stops at a predetermined pitch in parallel with the movement direction, and horizontal back and forth movement so that it crosses the work feeding mechanism. And a vertical cutting mechanism capable of moving up and down to cut the work at a predetermined pitch at a right angle to the moving direction of the work with intermittent movement of the work by the work feeding mechanism. . Further, the gist of claim 2 is that the horizontal cutting mechanism and the vertical cutting mechanism are unitized into an L shape in plan view.

The above technical means have the following effects. (Claim 1) A horizontal feed mechanism, which moves forward to a workpiece that is conveyed forward by the workpiece feed mechanism and stops, cuts the workpiece to a predetermined pitch parallel to the moving direction of the workpiece, and intermittently moves by the workpiece feed mechanism. The work is cut by a vertical cutting mechanism in a direction orthogonal to the moving direction of the work at a predetermined pitch. When the cutting in both the vertical and horizontal directions is completed, the work table is conveyed to the outside of the apparatus, and dust is removed and the plate material (piece) is taken out at that position. Therefore, it is possible to cut a plurality of modular rectangular plate materials (pieces) from the base substrate while moving the work in one direction by the work feeding mechanism. (Claim 2) A horizontal cutting mechanism that cuts a work parallel to its moving direction. A vertical cutting mechanism moves forward together with the forward movement, and the time for moving the vertical cutting mechanism up to the work is not wasted as a dedicated time. .

The horizontal cutting mechanism 3 is provided on the front surface above the entry space 15, and the vertical cutting mechanism 4 is provided on the right surface of the cutting unit 5.

As shown in FIGS. 1 and 2, the vertical cutting mechanism 4 includes a support portion 14 attached to the right surface of the cutting unit 5.
Then, the main body 24 to which the cutting blade 14 'in the Y direction is attached is vertically inserted, the screw rod 44 connected to the hydraulic servomotor 34 is screwed into the nut 54 attached to the main body 24, and the supporting portion 14 is attached.
A guide guide 64 for guiding the side portion of the main body 43 in the vertical direction is provided in the Y-axis.
It is supported so that it can move up and down.

The horizontal cutting mechanism 3 has a structure similar to that of the vertical cutting mechanism 4, is provided on the front surface of the cutting unit 5, and is supported by a hydraulic servomotor 33 so as to move up and down in the X direction.

The cutter unit 5 having the horizontal cutting mechanism 3 and the vertical cutting mechanism 4 is provided on the support surface 21 of the machine body 1 by screwing a screw rod 25 connected to the servomotor 15 provided on the support surface 21. It is supported by a guide rail 35 so as to move back and forth.

On the other hand, the work feeding mechanism 2 has a supporting surface outside the range on the supporting surface 21 where the cutter unit 5 intersects.
21 The pedestals 22 are attached to both sides, the guide rails 32 are installed over the left and right pedestals 22, and the work table 12 is movably placed on the guide rails 32, and the servo motor 42 is mounted on the work table 12. The work table 12 is moved in the X direction by screwing a screw rod 52 connected to the.

The work table 12 is provided with set pins 200 projecting from its upper surface on the four corners of the work 100 so that the work 100 does not move on the set pins 200. , The seat 22
The space between the lower surface of the cutter unit 5 and the support surface 21 of the machine body 1 is a space 62 for entering and exiting when moving forward.

In the horizontal cutting mechanism 3, the vertical cutting mechanism 4, and the work feeding mechanism 2, the work table 12 is temporarily stopped by the work feeding mechanism 2 at a predetermined position reaching the forward space of the cutter unit 5, and the cutter unit 5 is moved. While moving forward, the horizontal cutting mechanism 3 cuts the work 100 from the front side to the predetermined pitch in the X direction, and when the cutting in the X direction is completed, the work feeding mechanism 2 intermittently moves to the discharge side of the work table 12. The vertical cutting mechanism 4 cuts the work 100 in the Y direction when the work is intermittently stopped.

Further, a CCD is provided in the cutter unit 5 as a detecting means (shown in the figure) for detecting the cutting position of the work each time, and the size and deviation of the chip cut by the CCD are detected each time, By comparing it with the appropriate size of the memory part stored in the controller and the comparative value of the position, the cutting position, the cutting interval, etc. can be changed with the correction action of the horizontal cutting mechanism 3, the vertical cutting mechanism 4, and the work feeding mechanism 2.

Further, in the present embodiment, the embodiment of claim 2 is explained and the embodiment of claim 1 is not shown, but the horizontal cutting mechanism and the vertical cutting mechanism are integrated. Rather than a thing, after the horizontal cutting mechanism cuts in the X direction, the vertical cutting mechanism advances so as to cross the work and cuts the work in the Y direction with intermittent movement. The explanation is omitted.

Further, although the embodiment of claim 1 is not shown, the horizontal cutting mechanism 3 and the vertical cutting mechanism 4 are separately provided so as to be horizontally movable back and forth, and each of them is composed of a servomotor and a screw or the like. It is designed to be moved back and forth horizontally (not shown). In the present invention, the work table 12 is temporarily stopped by the work feeding mechanism 2 at a predetermined position reaching the forward space of the lateral cutting mechanism 3, and the lateral cutting mechanism 3 is advanced while the lateral cutting mechanism 3 is moved forward from the front side.

As described above, the present invention has the following advantages. (Claim 1) While the horizontal cutting mechanism advances toward the work placed on the work table, the work is cut at a predetermined pitch in parallel with the moving direction of the work, and the work is intermittently fed by the vertical cutting mechanism. Since it is a cutting device that cuts at a predetermined pitch in a direction orthogonal to the movement direction of the work, the work is carried in without rotating the cutting mechanism or sending and returning the work directly below the cutting mechanism in the machine body as in the conventional example. The modular rectangular piece can be cut while moving from the side to the discharge side, and the cutting is efficient. (Claim 2) Moreover, since the horizontal cutting mechanism and the vertical cutting mechanism are integrated, the cutting work time is further increased as compared with the case where the horizontal cutting mechanism and the vertical cutting mechanism are separately fed onto the work. It can be shortened and can be cut more efficiently.
