Problems solved by technology

Therefore, it is possible to clip where it should not be clipped, resulting in bad clipping
[0006] In order to stop the lifting of the cutter immediately, another method is to install a brake mechanism that restricts the movement of the cutter, but the disadvantage is that the device becomes complicated, and at the same time, it will cause malfunction due to the restriction of the movement of the cutter for no reason. s reason

Embodiment 1

[0031] figure 1 , figure 2 Shown is a first embodiment of the shearing device of the present invention.

[0032] In this embodiment, the case where the ceramic green sheet W in which a plurality of ceramic green sheets are laminated is cut in the manufacturing process of ceramic electronic components is exemplified, but the present invention is not limited thereto.

[0033] The ceramic blank W is placed on the horizontal upper surface (loading surface) 1a of the table 1, and fixed by vacuum suction. The table driving device 2 drives the table 1 horizontally, so that the ceramic blank W reaches a predetermined cutting position. Shear detection marks (not shown) are pre-formed on the side of the ceramic blank W, and the worktable drive device 2 of this embodiment consists of a motor 3, a ball screw 4 installed on the rotating shaft of the motor 3, and a working The nut 5 screwed with the ball screw 4 on the table 1, the guide rail 6 and the slide block 7 that guide the workt...

Abstract

Th invention provides a cutting device capable of immediately stopping cutting operation without performing unnecessary cutting to a ceramic block even if a cutting blade is moved continuously by inertia. This cutting device comprises a table (1) for placing the ceramic green block (W) thereon, a table drive means (2) horizontally driving the table (1) so that the ceramic green block comes to a prescribed cut position, a cutter block (10) having a cutting blade (13) for pressingly cutting the ceramic green block and a cutting blade lifting means (12) for vertically reciprocating the cutting blade, and a cutter block lifting means (20) for vertically driving the cutter block. When the cutting operation must be interrupted, the cutting blade lifting means (12) is stopped and, at the same time, the cutter block (10) is raised to prevent the ceramic block from being unnecessarily cut by the cutting blade (13).

Description

technical field [0001] The invention relates to a ceramic base plate shearing device and a shearing method using a cutter to shear a ceramic base plate. Background technique [0002] When manufacturing ceramic electronic components such as multilayer ceramic capacitors, ceramic green sheets (including ceramic green sheets or their laminates) must be cut to a specified size. As such a ceramic base plate shearing device, there are those shown in Patent Documents 1 and 2. [0003] The shearing device disclosed in Patent Document 1 includes a table on which a ceramic base plate is placed and moves intermittently at predetermined pitches in the horizontal direction, and a cutter that lifts up and down in the vertical direction to cut the ceramic base plate. [0004] The shearing device disclosed in Patent Document 2 uses a servo motor, an air cylinder, a linear motor, a hydraulic servo motor, a cam, etc. as a driving source for raising and lowering the cutter, and these driving ...
