In the present embodiment, the three degree of freedom of the Three Degree Of Freedom silk screen motion platform end is respectively X, Y, T, is such as shown
It is intended to shown in 4；
In the present embodiment, as shown in figure 5, a kind of printing of the draping adaptive printing device of crystal silicon photovoltaic solar battery
Method includes the following steps:
Step 1, installation complete machine, and complete the mark into plate positioning camera and Three Degree Of Freedom silk screen motion platform kinematic parameter
It is fixed；
In the present embodiment, after installing complete machine, four acquisition parameters into plate positioning camera are rationally set；Routinely
Method completes four calibration into plate camera and Three Degree Of Freedom silk screen motion platform kinematic parameter, makes four cameras and three certainly
It can be unified into unified coordinate system by the movement of degree silk screen motion platform.
Step 2 loads onto a pull spring net, determines and records the relative positional relationship of the silk screen Yu silk screen motion platform；
In the present embodiment, it is in Three Degree Of Freedom silk screen motion platform at benchmark position, then opens silicon wafer into plate four
In bearing ink pad, successively printed on every silicon wafer by silk screen it is primary, finally by rotation positioning platform successively by silicon wafer from printing
Station rotary triggers camera and takes pictures, by where printing mark object on silicon wafer in machine vision metrology photo into plate station
Position, the base position where obtaining indirectly and recording the silk screen in unified coordinate system.
Step 3, replacement silk screen, determine and record new web position；
