Plug hole and double-face solder mask screen printing machine and screen printing method

Abstract

The invention relates to a plug hole and double-face solder mask screen printing machine and a screen printing method. The screen printing machine comprises a rack, a first screen printing machine body, a second screen printing machine body and a third screen printing machine body, wherein the first screen printing machine body is arranged on the rack and used for achieving plug hole printing of a printing stock, the second screen printing machine body is used for achieving solder mask printing of one side of the printing stock, and the third screen printing machine body is used for achieving solder mask printing of the other side of the printing stock; the first screen printing machine body is connected with the second screen printing machine body through a first panel turnover machine; the second screen printing machine body is connected with the third screen printing machine body through a second panel turnover machine; and the first screen printing machine body, the second screen printing machine body and the third screen printing machine body each comprise a camera shooting counterpoint mechanism with an automatic counterpoint function and for shooting the printing stock, a printing mechanism for carrying out printing operation and a transferring mechanism for achieving transferring of the printing stock between the camera shooting counterpoint mechanism and the printing mechanism. The plug hole and double-face solder mask screen printing machine is high in producing efficiency, low in power consumption and low in total cost, and the problem that the color difference of product appearance is large can be avoided.

Description

technical field [0001] The invention relates to the technical field of screen printing, more specifically, to a screen printing machine and a screen printing method with plug holes and double-sided solder mask. Background technique [0002] With the development of society, automated production is an inevitable trend in the development of all walks of life. At present, the automated production of the PCB industry is mainly limited to the screen printing process of the PCB board. For PCB board products with high quality requirements, one of the steps in the screen printing process is to first use one screen printing machine to plug holes, and then use two screen printing machines to respectively print solder resist on both sides of the PCB board, or use one The first screen printing machine prints the double-sided solder mask on the PCB board by manually turning the board. At present, in the industry, three semi-automatic screen printing machines are usually operated by thre...

Problems solved by technology

This kind of production method is semi-automatic production, its production efficiency is low, the labor intensity of the operator is high, the production capacity of the product depends entirely on the operator, and there are people involved in the operation process, so that the quality of the product will be affected to a certain extent

In addition, its power consumption is large, and the speed of producing products is low.

Even if some users have adopted a fully automated production process to achieve this requirement, they still use plug holes, double-sided spraying methods and corresponding equipment to achieve this process requirement. The purchase cost of their double-sided spraying equipment is high, and the cost of ink use It is very high, and it takes a long time to clean, and the color difference of the product appearance is relatively large, which affects the appearance quality of the product
