Fully-automatic screen printer for sheets

Abstract

The invention discloses a fully-automatic screen printer for sheets. The fully-automatic screen printer for the sheets comprises a conveying unit arranged at the inner side of a rack, wherein the conveying unit is used for conveying a material to be processed and correcting a position to be printed, of the material; a printing unit is arranged above one end of the rack, and a discharge lifting unit is arranged at the other end of the rack; the discharge lifting unit is used for supplying the material to be processed and feeding back material lack information in time; a material taking mechanism is arranged at one end connected with the discharge lifting unit, of the rack; a vision unit is arranged above the material taking mechanism, and used for obtaining position image information of thematerial to be processed and on the conveying unit, and carrying out information feedback; and a material receiving mechanism is arranged on a part below the printing unit, of the rack. According tothe fully-automatic screen printer for the sheets, the accuracy of product alignment and printing is effectively increased, so that wider application range and higher universality are achieved, and electricity consumption and ink resource are saved; and moreover, the fully-automatic screen printer for the sheets is convenient to maintain and replace, so that the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a fully automatic sheet material screen printing machine. Background technique [0002] Screen printing machine is a machine that prints text and images with a screen printing plate. It is a general term for machines or equipment used to produce printed matter. Screen printing machine is a representative printing equipment in stencil printing machines. With the development of science and technology With the development, there are many kinds of screen printing machines such as flat, curved, forming, printing and dyeing, printed circuit and new rotary screen printing machines on the market to match the printing needs of different products. [0003] At present, most of the domestic sheet materials (especially FPC, that is, flexible circuit boards) are printed by semi-automatic printing equipment. During the operation of these equipment, manual loading and unl...

[0005] However, for the sheet material carrying device of this equipment, it is necessary to manually adjust the horizontal positioning mechanism and the vertical positioning mechanism to expand the discharging area every time the material is discharged, so as to facilitate the discharging. The discharging operation is cumbersome, which limits the production efficiency. The structure of the mechanism and the longitudinal positioning mechanism is relatively complicated. When maintenance is required, it is time-consuming and labor-intensive. Moreover, the sheet material carrying device can only manually check whether there are sheets on the storage table, and cannot be shut down when there is no sheet material on the storage table. Or alarm reminder, there will be "empty machine" running, wasting resources in terms of ink or electricity consumption

[0006] Moreover, the suction cups on the adsorption and transport mechanism of the equipment and the blanking suction cup assembly are all set on the connecting frame through the adjustment plate, and a suction cup is arranged at both ends of each adjustment plate, and the two suction cups on the same adjustment plate are adjusted with the adjustment holes on each adjustment plate. The spacing between them is to achieve the purpose of matching the size of the sheet to be adsorbed. However, this
