Abstract

The invention discloses an automatic solder paste printing press and a printing method thereof. The automatic solder paste printing press comprises an image collecting mechanism, a printed workpiece conveying mechanism and a net frame moving mechanism. The net frame moving mechanism comprises a net frame, a net frame movable frame, a net frame fixed frame, a linear guide rail and a moving device, wherein the net frame movable frame is connected with the net frame fixed frame in a sliding mode through the linear guide rail, the net frame movable frame is connected with the moving device, and the net frame is arranged on the net frame movable frame and correspondingly arranged on the upper portion of the printing position of a printed workpiece. An image collector of the image collecting mechanism is located above the printing position of the net frame, a moving controller controls the moving device to drive the net frame to move according to electric signals of the image collector, and therefore the image collector above the net frame can capture images of the characteristics of a net plate on the net frame and the characteristics of the printed workpiece. By means of the automatic solder paste printing press, the solder paste printing cycle can be greatly shortened, and production efficiency of the printed workpiece can be improved.

Description

technical field [0001] The invention relates to a printing device, in particular to an automatic solder paste printing machine capable of capturing images on the upper part of a screen frame printing position and a printing method thereof. Background technique [0002] In the surface electronics assembly process (SMT), automatic solder paste printing machines are usually aligned by machine vision to achieve high-precision stencil printing or stencil printing. The visual alignment technology in the existing automatic solder paste printing machine is to use the CCD camera installed between the stencil and the PCB board to move and obtain the stencil mark point through the upper photo and the PCB board mark point (mark) through the lower photo. point) image, and then after the image processing system analyzes and compares, the information is fed back to the motion control system to realize the alignment of the steel mesh and the PCB board, and complete the accurate printing of ...
