Abstract

The present invention relates to a screen printing machine, in particular to a direct-drive screen CNC scraper device, which includes a printing stroke unit for controlling the horizontal movement of the scraper and a scraper stroke unit for controlling the vertical movement of the scraper. The scraper stroke unit is controlled by a The connecting piece is arranged on the printing stroke unit; the scraper stroke unit includes a scraper servo motor, the output end of the scraper servo motor is connected with a ball screw, and the end of the ball screw is fixedly connected to the scraper through the scraper connecting piece. Compared with the existing technology, the present invention can adopt full digital control, precise motion control, direct drive of servo motor for motion power drive, eliminating many intermediate transmission parts, simple and reliable mechanical structure; it can be realized by changing the upper motion control code The required printing movement mode is digitized as the reference data of machine production, and the operation and control are easy.

Description

Technical field [0001] The invention relates to a screen printing machine, in particular to a direct-drive screen numerical control scraper device. Background technique [0002] In the prior art, the printing control of the screen printing machine is mainly a frequency conversion motor (scratch printing) and a pneumatic pressing knife method. The point motion control method is adopted, which cannot adapt to various printing process changes more flexibly. Only experienced operation and control personnel can master the operation of the machine, and the mechanical structure is relatively complicated, and it is difficult to ensure accuracy after a long period of movement. Therefore, many screen printing heads generally suffer from greatly reduced mechanical performance after one year of use. Summary of the invention [0003] The main purpose of the present invention is to overcome the shortcomings of the prior art and provide a direct-drive wire mesh numerical control scraper device, ...
