Offline and online integrated jet-printing system of printed circuit board

Abstract

The invention relates to the field of printed circuit boards, and discloses an off-line and online integrated inkjet printing system for printed circuit boards, comprising a horizontally placed substrate (1), a mobile operating platform (2), and two image capture devices (3) , a mobile jet printing curing device (4) and a gantry (5); the mobile operating platform is movably installed on the base plate, and the moving track of the mobile operating platform is in the direction of ±Y; the gantry is fixed on the base plate , and the fixed direction of the gantry is the X direction; the front side of the gantry is provided with two image capture devices that can move independently in the ±X direction; Curing device; the X direction and the Y direction are two directions perpendicular to each other on the horizontal plane. The spray printing system of the present invention has low cost, can realize offline and online production modes, has a high degree of automation, and greatly improves work efficiency.

Description

technical field [0001] The invention relates to the field of printed circuit boards, in particular to an offline and online integrated jet printing system for printed circuit boards. Background technique [0002] With the rise of digital inkjet printing technology, the printed circuit board industry urgently needs inkjet printing technology to replace traditional silk screen technology or multiple pattern transfer lithography technology to achieve low energy consumption, no pollution, automatic digital mass production, and the current existing printing system such as figure 1 As shown, after the PCB circuit board 6 is placed on the operating platform 7 by a single operator or a single mechanical arm, the platform Y moves forward to the bottom of the hoisting gantry, and the combination of the CCD device 8 and the printing and curing device 9 is -X The CCD device takes pictures of the first target point 61 and the second target point 62 on the PCB circuit board respectively,...

AI Technical Summary

Problems solved by technology

This kind of off-line inkjet printing system is suspended and installed on one side of the hoisting gantry due to the combination of the CCD device and the inkjet printing device. The nozzle maintenance of the jet printing and curing device, that is, nozzle cleaning, cannot be carried out at the same time, making the whole process time-consuming, and the PCB circuit board can only be input and output from the front end of the equipment, and the degree of automation is not high, resulting in the inability to carry out automatic digital mass production
