Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Refering to fig. 1, the board transport method of the embodiment of the present invention includes mainly：
S01, substrate enter downstream board from upstream board；
S02, judge downstream board whether failure；
S03, when downstream board breaks down, enable the buffering board positioned at downstream machine platform upstream, and close buffer
The first in, first out function of platform ensures that the transmission speed of substrate does not interfere with follow-up process, and producing line is enable to be flowed with normal tact time
Piece, at this point, substrate enters downstream board from upstream board successively buffered board；
S04, the quantity n for buffering the substrate in board is determined0；
S05, according to buffering board in substrate quantity n0The transmission side of substrate is determined with the magnitude relationship of default maximum
Formula specifically includes：
S051, when buffering board in substrate quantity n0When less than default maximum, then start timing, in elapsed-time standards
After t, buffering board is closed, substrate flows into downstream board directly from upstream board, wherein t >=n0*t0, t0It postpones for single substrate
Rush the time that board is carried to downstream board, it is ensured that the substrate in buffering board can be all discharged in the time t of setting, this
Kind method is suitable for the quicker situation of troubleshooting.Wherein, the value of the default maximum depends on the tact of production line
Time, so that the transmission progress of substrate is kept within the scope of the beat with production line.
S052, when buffering board in substrate quantity n0When reaching default maximum, representing fault can not be located quickly
Reason continues with buffering board from upstream board to downstream board transmission base plate, when the buffered board of substrate then without timing
Into downstream board until the quantity n of the substrate in buffering board0When reaching default minimum, then illustrates trouble shooting, then may be used
Board is buffered to close, substrate flows into downstream board directly from upstream board.
Preferably, buffering board is multiple, multiple buffering boards be located at different upstream boards and downstream board it
Between.For example, one of upstream board be baking board, one of downstream board be first detection board, baking board and
It is set between first detection board there are one board is buffered, which can be used as substrate from baking board to the first detection machine
There is heap piece or substrate cut-off, wherein baking board can to prevent the first of downstream to detect board in the buffer part of platform transmission base plate
To be prebake conditions board, board is toasted after can also be, the first detection board can be used for carrying out sampling observation or full inspection to cured effect.
Alternatively, one of upstream board is developing machine platform, one of downstream board is the second detection board, developing machine platform and second
