Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
220 words
A device for the printing and assembling of a plurality of ceramic sheets used in the manufacture of multilayer ceramic capacitors and the like comprising a rotatable transport means for moving ceramic sheet to various means for performing various respective processing phases performed by said device, wherein said transport means comprises a multi-sided drum rotatable abut a horizontal rotational axis, wherein each side of said drum comprises a drum flat having alignment pins projecting therefrom, a loading means for loading ceramic sheet onto said transport means, a ceramic sheet supply means for dispensing ceramic sheet to said loading platform, a screening means for applying a layer of ink onto said ceramic sheet, said screening means including a frame having alignment pins projecting therefrom, a stacking means for assembling a plurality of said ceramic sheets after screening by said screening means, said stacking means including a stacking platform having alignment pins projecting therefrom, means for precisely aligning said alignment pins of said screening means and said stacking means relative to the alignment pins of said transport means, means for installing a pallet onto said stacking means on which said plurality of ceramic sheets is assembled, means for moving said pallets from said stacking means after said plurality of ceramic sheets has been assembled, and control means including a central processing unit.
Claim 2
Independent Claim
220 words
A device for the printing and assembling of a plurality of ceramic sheets used in the manufacture of multilayer ceramic capacitors and the like comprising a rotatable transport means for moving ceramic sheet to various means for performing various respective processing phases performed by said device, wherein said transport means comprises a multi-sided drum rotatable abut a horizontal rotational axis, wherein each side of said drum comprises a drum flat having alignment pins projecting therefrom, a loading means for loading ceramic sheet onto said transport means, a ceramic sheet supply means for dispensing ceramic sheet to said loading platform, a screening means for applying a layer of ink onto said ceramic sheet, said screening means including a frame having alignment pins projecting therefrom, a stacking means for assembling a plurality of said ceramic sheets after screening by said screening means, said stacking means including a stacking platform having alignment pins projecting therefrom, means for precisely aligning said alignment pins of said screening means and said stacking means relative to the alignment pins of said transport means, means for installing a pallet onto said stacking means on which said plurality of ceramic sheets is assembled, means for moving said pallets from said stacking means after said plurality of ceramic sheets has been assembled, and control means including a central processing unit.
Claim 3
Dependent Claim
27 words
