Cutting device and method

Abstract

When a disk-like cam 15 rotates by 180[deg.], a cutting blade 23 reaches the lowest point and cuts a ceramic laminated block 30. When a motor 9 for driving cutting means rotates, the cutting blade 23 is changed from fall to rise. When an edge of the cutting blade 23 is exposed from the ceramic laminated block 30, a trigger signal is transmitted from a trigger signal generating part to an image processing part. When the image processing part receives the trigger signal, both end faces of the ceramic laminated block 30 are picked up by CCD cameras 5a, 5b, respectively, and a picked-up image for detecting a cut predetermined position is obtained. During the period, the cutting blade 23 continues to rise.

Description

technical field [0001] The invention relates to a cutting device and a cutting method. Background technique [0002] The manufacture of laminated ceramic electronic components such as laminated ceramic capacitors undergoes the following steps in sequence, including the process of printing multiple internal electrodes on the surface of the ceramic raw material substrate; The process of pressurizing and forming unsintered ceramic laminate blocks; the process of cutting the ceramic laminate blocks according to the configuration of the internal electrodes and cutting off the laminated ceramic chips one by one; the process of sintering the cut laminated ceramic chips process; and a process of forming external electrodes on the sintered laminated ceramic chip. [0003] However, in order to cut the ceramic laminate block at predetermined positions into laminated ceramic chips, printing marks for cutting and positioning are also printed in the process of printing a plurality of int...

Problems solved by technology

[0006] However, the structure of the existing cutting device cannot detect this moment, so after confirming that the cutting tool has reached the highest position of the up and down movement, the positioning mark detection operation is started.

Therefore, there is a problem that time is unnecessarily wasted when switching from the cutting operation to the positioning mark detection operation.

[0007] In addition, because the structure of the conventional cutting device cannot detect the time, a series of operations such as the cutting operation, the positioning mark detection operation, and the table moving operation have to be performed sequentially as a last resort.

Since it is executed in sequence, the following cutting actions cannot be performed before the positioning mark detection action and table movement action are completed

Therefore, there is a problem that the cutting action becomes an intermittent action, and the processing speed is not high
