Full-automatic silk screen processing platform and silk screen technology thereof

Abstract

The invention discloses a full-automatic silk screen processing platform and a silk screen technology thereof. The full-automatic silk screen processing platform comprises a working platform, a turntable, an alignment platform, a material precise transfer mechanism, a material detection mechanism, a silk screen platform and a silk screen mechanism, wherein the turntable is rotatably arranged on the working platform; two or single or more than two silk screen processing production lines are arranged in the front and back of the turntable; each silk screen processing production line comprises a loading station, a silk screen station and an unloading station; the loading stations, the silk screen stations and the unloading stations of two silk screen processing production lines are gradually arranged; and the actions of material off-line precise positioning, material carrying, material position detection, station switch, silk screen, unloading and feedback are finished gradually. In the invention, by adopting the 6-station turntable structure design, integrating double silk screen processing lines and adopting the first-positioning and later-detection technology design, the steps of the silk screen technology are effectively simplified, and the silk screen efficiency and yield are increased; and by adopting the structural design of expandable material positioning and silk screen processing, the platform adaptability and universality are strong.

Description

technical field [0001] The invention relates to the field of silk screen printing of sheets, in particular to a fully automatic silk screen processing platform and a silk screen process for printing touch screen window glass. Background technique [0002] Screen printing belongs to stencil printing, and it is called the four major printing methods together with lithography, embossing, and gravure printing; stencil printing includes transcription, perforated pattern, inkjet and screen printing, etc. The principle of stencil printing is : The printing plate (the hole that can pass the ink is made on the base of the paper film plate or other plates) when printing, the ink is transferred to the substrate (paper, ceramics, etc.) through the holes of the stencil through a certain pressure to form a pattern icon or text. Screen printing is composed of five major elements, namely, screen printing plate, squeegee, ink, printing table and substrate; the basic principle of screen prin...

AI Technical Summary

Problems solved by technology

This method makes the cost of silk screen printing very high, and the process is relatively long, the structure is complex, and the requirements for debugging personnel are very high. In addition, the CCD positioning can only be performed on a single piece of sheet, and multiple pieces of silk screen printing cannot be realized at the same time. The silk screen printing can be completed at the highest 20pcs / min speed

[0005] The Chinese invention patent "A fully automatic precision screen printing machine" with the announcement number 203371890U discloses an automatic screen printing processing equipment. The equipment uses a turntable as a station switching structure. The turntable includes four operating stations: CCD alignment station, screen printing station, and blanking station; the equipment has the following defects in the actual operation process: 1. The turntable can only complete single-screen screen printing, and the space of the turntable cannot be fully and effectively used, and the efficiency of silk screen printing is low; 2. In the actual screen printing process, limited by the limitations of the CCD positioning mechanism itself, the detection and positioning of a single piece of material can only be completed at the CCD alignment station. The process is long and the production capacity of silk screen printing is low; The positioning system 4 and the alignment platform 53 are designed in cooperation with each other. Before the screen printing, the visual positioning system 4 is used to take pictures. After obtaining the position of the material, the screen printing position of the screen 51 is adjusted through the alignment platform 53 to ensure the accuracy of the screen printing. This design The process manufacturing cost is high, and it is only suitable for single-piece material printing; 4. The structural design of the whole set of equipment and the silk screen printing process are complex, high cost, and low efficiency
