Double-faced character printing method for PCB

Abstract

The invention discloses a double-faced character printing method for a PCB. The method includes the following steps that characters on the first face are printed, specifically, the PCB to be printed is conveyed to a first CCD automatic printer for printing of the characters on the first face; a board cushioning tool is fixed, specifically, the board cushioning tool is fixed to a table board of a second CCD automatic printer, and empty grooves are formed in the positions where the board cushioning tool and the characters printed on the first face coincide; board overturning is conducted, specifically, the PCB with the characters printed on the first face is conveyed to a board overturning machine to be overturned, and the printed face of the PCB is placed on the board cushioning tool which is fixed to the table board of the second CCD automatic printer; characters on the second face are printed, specifically, the second CCD automatic printer is used for printing the characters on the second face of the PCB; board baking is conducted, specifically, the PCB with the characters printed on the second face is conveyed to a baking oven to be baked; and cooling is conducted, specifically, the PCB baked through the baking oven is cooled and collected. By means of the double-faced character printing method, the problems that during double-faced character printing, when the characters on the second face are printed, the characters are messed while not dried, ink on the characters is not dried, and green ink is messed can be effectively solved.

Description

technical field [0001] The invention relates to a PCB double-sided character printing method. Background technique [0002] The current character operation method is to use a semi-automatic or CCD automatic printing machine to print single-sided characters, and print the second-sided characters after drying. This kind of operation has problems such as long production cycle, high energy consumption of the baking plate, and frequent transshipment. [0003] After the characters on the first side are printed, the characters on the second side are printed directly. When printing the characters on the second side, there will be problems such as the characters on the first side are not dry and scratched, the green oil is scratched, and the printing support is not enough to prevent the characters from being greased. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention aims to provide a PCB double-sided character printing method, wh...
