Screen printing machine capable of automatically choosing silk screen plates

Abstract

The invention relates to a screen printing machine for automatically selecting a screen plate, which includes a casing and a transmission mechanism arranged on the casing, a printing mechanism and a printing plate mechanism. The positioning mechanism includes a fixing plate, a first motor, a connecting block, a first wire Rod, limit rod, sliding block and code scanner, the selection mechanism includes cylinder, rotating assembly and clamping assembly, the screen printing machine that automatically selects the screen plate, drives the code scanner to scan the barcode on each screen plate through the positioning mechanism , each barcode corresponds to a unique screen version. When the barcode of the required screen version is scanned, the scanner sends a signal to the PLC, and the PLC stops the positioning mechanism and makes the selection mechanism work, and automatically selects the Compared with manual selection, the required screen plate reduces labor intensity, saves time and effort, and thus improves printing efficiency.

Description

technical field [0001] The invention relates to the field of printing equipment, in particular to a screen printing machine for automatically selecting screen plates. Background technique [0002] The full name of the screen printing machine is: "screen printing machine", which is a device that prints solder paste or patch glue onto the PCB pad through the screen. It is widely used for its advantages of wide range of use, good quality and low cost. The screen plate is a printing plate made of screen, and the graphic part can leak ink. It is the first element of screen printing and plays a decisive role in the performance and characteristics of screen printing. [0003] At present, before printing, the existing screen printing machines need to manually select the required screen plate from many screen plates. If the number of screen plates is large, the labor intensity will be increased, time-consuming and laborious, resulting in low printing efficiency. , When the existing...

Problems solved by technology

[0003] At present, before printing, the existing screen printing machines need to manually select the required screen plate from many screen plates. If the number of screen plates is large, the labor intensity will be increased, time-consuming and laborious, resulting in low printing efficiency. , When the existing voltage stabilizing circuit is running, the working noise is large, which not only affects the stability of the voltage output, but also has a large voltage difference, making the voltage stabilizing effect poor
