When the angular regulation of the cutting edge 52 has been completed in this way, the cutting work of the workpiece W such as a laminated substrate is started.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device. More specifically, the present invention relates to a support structure for a cutting blade of a cutting apparatus used for individually cutting a plurality of works such as a laminated substrate and taking a plurality of works.

[0002]

TECHNICAL BACKGROUND In general, a plurality of laminated substrates, which are a kind of works of a cutting processing apparatus, are taken from laminated material plates for reasons such as shortening of tact time. To describe the manufacturing process of the laminated substrate in detail, after punching a single material plate to open holes for desired circuit connections, printing for circuit connections connecting the holes is performed.
Then, one material plate on which each desired printing is applied is laminated and press-molded. This press-molded laminated material plate is continuously cut by a cutting device,
The individual substrates are sintered to complete a laminated substrate. In the final step, the sintering process, the outer dimensions of the laminated substrate change due to heat shrinkage, but in order to keep it within the dimensional tolerance that takes this into account, a higher processing accuracy is required in the cutting process before the sintering process. Has been done.

[Prior art]

Conventionally, as this type of cutting apparatus for a work such as a laminated substrate, for example, a work feeding mechanism for moving the work in a certain direction, and a work feeding mechanism for vertically moving a flat blade-shaped cutting blade. It is known that a cutting mechanism that cuts a work sent by a device with a desired pitch. This cutting mechanism is equipped with an actuator for vertical movement, a flat blade-shaped cutting blade for cutting the work material, and a vertical movement unit for transmitting the vertical movement output of the actuator to the cutting blade. It is fixedly connected and fixed to the column.

In this conventional cutting processing apparatus, as a measure for ensuring the above-mentioned high processing accuracy, the cutting mechanism itself is manufactured with high accuracy, and the dimension is set sufficiently for installation of the apparatus. I was being treated. However, since there is a variation in accuracy of the essential cutting blade, it is necessary to perform the work of attaching the cutting blade so as to obtain a desired accuracy. By the way, with this variation in the accuracy of the cutting blade, the cutting edge angle of the cutting blade should be formed symmetrically to the left and right, but in reality it is formed asymmetrically, so that with this asymmetrical cutting blade If the work is cut continuously, the cut surface will be cut into uneven work with poor accuracy. Therefore, instead of directly attaching the cutting blade to the blade mounting surface provided at the lower part of the lifting / lowering moving section, a shim (strip-shaped thin plate) is appropriately sandwiched between the blade and the blade mounting surface to divide the blade angle into two equal parts. The cutting blade was attached so that the division (bisector) was perpendicular to the work.

[0005]

However, the work of sandwiching a shim of different thickness between the blade mounting surface and the cutting blade is
Most of the time, it is not always possible to obtain the desired accuracy in a single operation, but it is very troublesome at the same time that the cutting blade is mistakenly cut during operation because the desired accuracy is obtained by selecting or stacking shims several times. There was a risk of injury. Since this cutting blade is a consumable part, making such a dangerous and delicate adjustment each time it is replaced greatly hinders productivity, and, moreover, it should be mounted accurately on the blade mounting surface. Since the cutting blade is forcibly inclined and attached, bending stress is generated in the cutting blade due to the intervening shim, which is one of the causes of shortening the life of the cutting blade.

The present invention has been made in view of the conventional circumstances, and its object is to perform a cutting process in which the cutting edge angle of a cutting blade having poor accuracy can be easily corrected without applying a deforming force to the cutting blade. It is to provide a device.

[0007]

That is, the cutting blade is continuously tilted and fixed so that a line segment (bisector) that bisects the cutting edge angle in a direction orthogonal to the crossing direction of the cutting blade is perpendicular to the workpiece. Thus, the above problem is solved by absorbing the accuracy error of the cutting blade. Here, the configuration of the cutting mechanism includes an actuator for raising and lowering movement, a flat blade-shaped cutting blade, a raising and lowering moving portion for transmitting the raising and lowering movement output of the actuator to the cutting blade, and a support plate portion for supporting these.

On the other side, the screw is rotated to continuously adjust and fix the swing angle to rotate the screw to utilize the pushing force of the screw tip (projection amount of the screw tip). Examples thereof include those utilizing repulsive force, cylinders capable of reciprocating output, and those utilizing a solenoid. Further, the installation location may be provided on the column, above or below the support portion, provided on the cutting mechanism, or provided upright from the base surface of the cutting processing device.

According to the second aspect, the supporting plate portion is pushed by the screw portion, and the cutting blade direction is delicately corrected so that the bisector of the cutting edge angle becomes an angle perpendicular to the work.

[0032]

As described above, the present invention has the following advantages. (Claim 1) The cutting blade is continuously adjusted so that a line segment (bisector) obtained by bisecting the cutting edge angle in the orthogonal direction by the adjusting and fixing means with respect to the crossing direction of the cutting blade is perpendicular to the work. Since it is tilted and can be fixed, the cutting blade is directly attached to the blade mounting surface without adjusting by tilting the cutting blade by inserting a shim or other inclusion between the cutting blade and the blade mounting surface. It becomes possible to do. Therefore, while eliminating the trouble of adjusting the cutting blade by attaching or detaching it many times and inserting a shim between the cutting blade and the blade mounting surface, you can avoid the danger (injury) associated with the adjustment work and adjust it. Since the time can be shortened, it is possible to provide a cutting device which is safe, simple and reliable, and can be expected to improve productivity. Further, since the cutting blade can be normally attached to the blade mounting surface, a deforming force (bending stress) is applied to the cutting blade like the conventional fixing means that tilts the cutting blade with respect to the blade mounting surface.
The deforming force does not cause deterioration of the durability of the cutting blade, and the cutting blade can be used with the original durability. According to a second aspect of the present invention, there is provided a structure in which the adjusting and fixing means includes a screw portion for pushing the support plate portion from one of the swinging directions, and a spring portion for elastically biasing the support plate portion in a direction against the screw portion. Therefore, the structure of the adjusting and fixing means can be simplified. Further, the work is cut while the cutting blade is tilted, but the amount of tilt is slight and the cutting surface is formed symmetrically. (Claim 3) Since the second lifting rod is pushed so that the bisector of the cutting edge angle becomes an angle perpendicular to the work in the screw part, the adjusted cutting blade moves ideally, In other words, since the work is moved vertically, it is possible to obtain a highly accurate cut surface with left-right symmetry. (Claim 4) Since the lock portion is provided, it is not necessary to use a material having a high spring coefficient so as not to be compressed or laterally bent during cutting. Therefore, since the tolerance of spring selection is increased, flexibility is provided even when parts are replaced.
