when the first printing workbench 202 of the current row performs character jet printing in the second manufacturing process, namely, the character printing station 11 performs character jet printing, the second printing workbench 204 of the subsequent row moves from the alignment station 9 to the first manufacturing process directly below the printing trolley beam 106 along the Y-axis direction, namely, the solder mask printing station 10 repeats the jet printing solidification process of the first printing workbench 202, then the printed PCB circuit board is unloaded from the board receiving station 12 at the rear end of the machine assembly 1 by the first printing workbench 202 of the current row, and descends to the front of the machine assembly 1, and simultaneously, the second printing workbench 204 of the subsequent row continues to move from the solder mask printing station 10 along the Y-axis direction to the character printing station 11 directly below the printing trolley beam 106 to repeat the jet printing solidification process of the second manufacturing process of the first printing workbench 202, at this time, the first printing workbench 202 which is reloaded with the PCB circuit board to be jet printed in front of the machine assembly 1 moves forward to the position below the CCD beam 105 along the Y-axis again, and (4) performing the same work flow cycle, and repeating the flow of the first printing workbench 202 in the forward row by the second printing workbench 204 in the backward row to continue to move to the board receiving station 12 at the rear end of the machine assembly 1 to unload the printed PCB and descend to return to the front of the machine assembly 1. The first printing workbench 202 and the second printing workbench 204 continuously circulate the work flow, and the whole work flow is finished in one go without interfering with each other: the table top of the first printing workbench 202 is photographed and aligned, the table top of the second printing workbench 204 is placed, the table top of the first printing workbench 204 is subjected to welding prevention printing, the table top of the second printing workbench 204 is photographed and aligned, the table top of the first printing workbench 202 is subjected to character printing, the table top of the second printing workbench 204 is subjected to welding prevention printing, and the table top of the first printing workbench 202 is subjected to character printing while the rear end of the machine table assembly 1 is unloaded. The PCB circuit board advances back and forth in the machine table assembly 1, and the operation requirement of an automatic production line is well met.

Refer to fig. 3 and to sum up, the utility model discloses a two kinds of production modes, the production mode that goes out after going forward more walks a station than the production mode that goes out before going forward, the board station 12 that receives in board assembly 1 rear promptly has greatly made things convenient for PCB circuit board manufacturer to arrange demand and production place condition free choice production mode according to the transfer machine of self, and application scope is extensive.
