Automatic solder paste printing machine with printing material stacking prevention and easy demoulding functions

Abstract

The invention discloses an automatic solder paste printing machine with printing material stacking prevention and easy demoulding functions. The machine structurally comprises an equipment main body,a control panel, a working panel, a steel net frame, a pneumatic stacking prevention device, a movable frame, a scraping plate and an electric cabinet. The beneficial effects are as follows: accordingto the machine, a pushing structure is utilized to assist the scraping plate to carry out ink return printing, and meanwhile, and the heating plate is utilized to avoid the phenomena of poor printingeffect, unclear printing and the like caused by the hardening of the solder paste due to the chemical action caused by long-term exposure to the air. According to the method, a stacking-free mechanism and a pneumatic anti-sticking film structure are mutually matched, so that when the solder paste is pushed to the outermost sides of the two sides, the solder paste is able to flow towards the inside of the frame under the interaction of an L plate and an arc-shaped air bag so as not to accumulate on the outermost sides for a long time and harden to result in mixing of new and old printing materials; and meanwhile, the printed template is subjected to air blowing type demolding under the pneumatic action of the pneumatic anti-sticking film structure, so that the difficulty in demolding is avoided, and the template and the printing material are printed again in the demolding process.

Description

technical field [0001] The invention relates to the field of printing machines, more specifically, an automatic solder paste printing machine with printing material anti-stacking and easy mold release. Background technique [0002] Printing is one of the four great inventions of our country. It has a great influence on the world and is an important creation of the working people in ancient China. With the passage of time and the gradual development of science and technology, printing is based on the original, diffracting Many new printing technologies have been developed, including: 3D color printing, solder paste printing, etc., and printing is mainly to transfer the ink to paper, fabrics, etc. , plastic products, etc., to reproduce the content of the original manuscript in batches, the corresponding products need to be printed by the corresponding printing machine, when using the solder paste printing machine for printing circuit boards, etc., it is used The process has t...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an automatic solder paste printing machine with anti-stacking of printing materials and easy demoulding, so as to solve the problem of the prior art that the solder paste is concentrated when the equipment is printing. It is placed inside the screen frame and scraped back and forth to achieve printing. Therefore, under the influence of the characteristics of the solder paste itself, it is exposed to the air for a long time. The surface of the solder paste is easy to oxidize or react with other chemical substances, resulting in slight cracks on the surface. Hardened, and in the process of scraping back and forth, the solder paste is easily scraped to the outermost edge of the four sides of the frame and is outside the range of movement of the scraper, and then the solder paste will harden directly without movement. It leads to difficulty in cleaning and serious waste of printing materials. At the same time, in the process of demoulding after printing and dyeing, due to the characteristics of printing materials, there will be a momentary adhesion during the demoulding process, which makes it difficult to demould. Prone to multiple mixed printing and dyeing defects
