A manufacturing method thereof is also provided. The manufacturing device comprises a sheet material conveying component for continuously conveying the ceramic sheet materials towards a preset direction; a sheet material cutting component for cutting ceramic sheet materials into a preset length; a sheet material laminating component for laminating the cut ceramic sheet materials with a preset length; and a plurality of sheet material transfer printing component which makes the cut ceramic sheet materials peeled from the sheet material conveying component and transfer printing the cut ceramic sheet material on the sheet material laminating component. One sheet transfer printing component and another sheet material transfer printing component make the cut ceramic sheet material alternately transfer printed and laminated.

Description

technical field [0001] The present invention relates to a multilayer electronic component manufacturing apparatus and a multilayer electronic component manufacturing method for manufacturing multilayer electronic components such as multilayer ceramic capacitors. Background technique [0002] In the prior art of Patent Document 1, in a method of manufacturing a laminated ceramic capacitor, a mother ceramic green sheet supported by a carrier film is provided, peeled off by a suction roller, and the mother ceramic green sheet is bonded by a transfer / press bonding method. High-precision lamination on a flat table to obtain a laminated body. In the prior art of this patent document 1, long ceramic green sheets cannot be supplied continuously, and intermittent supply is required. [0003] In the prior art of Patent Document 2, in a method of manufacturing a laminated ceramic capacitor, a ceramic green sheet on which internal electrodes are printed is provided to a ceramic green s...

AI Technical Summary

Problems solved by technology

[0006] However, in the prior art of the aforementioned Patent Document 1, when the ceramic green sheets are stacked on the rectangular stacking table, due to the action of peeling the supplied ceramic green sheets with the suction rolls and the movement of the ceramic green sheets from the suction rolls to the stacking table. Actions that are stacked cannot be performed at the same time, so each action becomes an intermittent action

In order to supply the ceramic green sheet intermittently, it is necessary to make the supply reel itself intermittently operate, or to have a buffer between the continuously rotating supply reel and the peeling part on the suction roller, and the price of the device will decrease. Higher, the volume will become larger, and the energy consumption such as power will also increase

In addition, with intermittent operation, there are main causes of quality variation (damage, deformation during transfer and peeling of ceramic green sheets, stacking position deviation due to mishandling, and contamination due to scattering of chips)

In addition, here, since the suction roller is heavy, the inertia during acceleration and deceleration is large, and it is difficult to achieve high speed.

Also, stack offsets can occur

[0007] On the other hand, in the prior art of the above-mentioned Patent Document 2, in the case of employing the steps including forming the ceramic green sheet and forming the internal electrodes, the sheet after forming the ceramic green sheet and forming the electrodes is formed into a rectangular laminated body In the lamination operation, the operation of feeding ceramic green sheets to the lamination process is an intermittent operation

Accordingly, the formation of ceramic green sheets and the formation of internal electrodes are stopped for each layer. In this case, in each formation process, material loss and quality deviation occur after the formation starts until a continuous stable state is reached. (Green film thickness, electrode film thickness, electrode area deviation), and sheet ribbing

In addition, due to intermittent operation, energy consumption such as power will increase

In addition, since the rollers are heavy, the inertia during acceleration and deceleration is large, making it difficult to achieve high speed.
