After the liquid injection device 20 is positioned on the liquid supply device 50, just fix the mounting plate 16 of the liquid injection device 20. At this time, the alignment of the liquid injection device 20 with respect to the liquid supply device 50 and the residual liquid collection device 70 has been completed. The second positioning After the assembly 60 is removed, the liquid supply device 50 , the liquid injection device 20 and the residual liquid collection device 70 can perform subsequent operations.

It can be understood that the first positioning component 30, the second positioning component 60 and the calibration component 80 are used before the liquid injection device 20 performs liquid injection, that is, the position of the liquid injection device 20 is adjusted before the liquid injection device 20 works. Ensure the accuracy of subsequent injections.

In addition, it needs to be explained that in the prior art, in order to avoid excessive position deviation, manual position adjustment can be performed, and manual manual position adjustment requires adjusting the positions of the turntable 11 and the liquid injection device 20 in sequence, and the operator When adjusting by observation, the adjustment accuracy and adjustment efficiency are lower. However, using the liquid injection system in the above embodiment and performing position adjustment through the first positioning component 30, the second positioning component 60 and the calibration component 80, the adjustment accuracy and adjustment efficiency are higher. high.
