Description

{Sheet Align-Transfer Apparatus}

The present invention relates to a sheet aligning and conveying apparatus (100), and a sheet aligning and conveying apparatus for aligning and conveying a sheet in the XY-theta axis direction, comprising: an X-axis conveying frame (110) Axis direction on the Y-axis guide 161 installed on the conveyance base 120. The Y-axis guide 161 is driven by the X-axis aligning and conveying driving means 130 on the Y- Axis driving unit 140. The first Y-axis alignment driving unit 140 drives the first Y-axis alignment driving unit 140 and the second Y- And the other side positioned in the diagonal direction on one side is an alignment plate 170 driven by a second Y-axis alignment driving means 150; and a vacuum adsorption Plate 180, It is directed to the sheet by the transfer device (100) according to claim.

Generally, in order to increase capacitance of a capacitor such as a multi-layer ceramic capacitor (MLCC) which is a very small capacitor, it is necessary to increase a counter electrode area, reduce a distance between electrodes, or apply a dielectric material having a large dielectric constant between electrodes However, in order to increase the capacity while keeping the size small, the thickness of the dielectric material film or thin film is mainly made thinner, and then several tens to several hundreds of layers are laminated and connected in parallel. A dedicated laminator is used.

Thin-film micro-MLCCs manufactured by these thin film MLCC-dedicated laminators can be used for special purposes such as memory modules, tuners, mobile devices, military devices, medical devices, aircraft, automobiles, etc. in addition to IT products (mobile phones, PCs, D- And is widely used in a wide variety of fields where small capacitors are required. Particularly, since the inductance is low, it is superior in noise elimination effect at high frequencies compared with other capacitors, and thus it is applied to mobile phones, satellites, etc., and plays a role as a capacitor having high capacity and high reliability. In general, MLCC is a versatile component that requires more than 250 mobile phones (smartphones are twice as large as ordinary mobile phones), about 300 in notebooks, and about 700 in LCD TVs.

On the other hand, as electronic devices such as smart phones, portable communication devices, tablet PCs, notebooks, and smart TVs have become more sophisticated, the size of thin-film micro-MLCCs used therefor is becoming smaller and smaller. Considering that it is necessary to use the MLCC as a basic element of a circuit structure, the technology for a thin film MLCC-dedicated laminator for manufacturing such a thin MLCC is inevitably an important issue not only now but also in the future.

As for the sheet laminating process and the apparatus, various prior arts have been disclosed and disclosed in addition to the "automatic ceramic green sheet laminating method and apparatus (Korean Patent Laid-open No. 10-2007-0035222)" of Patent Document 1 below. In this case, in order for each of the sheets to be laminated to have an accurate position and to be stacked, the position of the sheet is measured using a measuring means such as a sensor before the stacking step as described in the above Patent Document 1, A step of aligning with respect to the axis is essential.

In the sheet stacking apparatus (Korean Patent Laid-Open No. 10-2009-0100888) of the following patent document 2, a detailed description of the invention and an apparatus for aligning such a sheet are described in "XY & The table is installed so as to be raised / lowered by the head elevating mechanism and includes a top / bottom plate, a ball screw linear mechanism / rotary member installed between the upper and lower plates and finely adjusting the lower plate in the X / Y / And the constituent contents are disclosed. 1 is a more detailed view of the configuration of the alignment apparatus. (Note that the vacuum adsorption plate is omitted in FIG. 1 for clarity of the operation part.)

However, the conventional aligning apparatus has a problem in that it requires only a separate component to transfer the sheet, which is merely capable of aligning the sheet.

Further, in order to align the plate 1 on which the sheet is seated in the XY-theta axis direction as shown in Fig. 1, the X-axis driving means 2 and the Y-axis driving means 3, (Bearings) 5 must be installed at four corners of the plate 1, and the cross roller stages (bearings) 5 are complicated and relatively expensive components, and are suitable for quick operation .

Further, there is a problem that the load of other components such as a vacuum adsorption plate mounted on the plate 1 is supported only by the cross roller stage (bearing) 5.
