Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

With reference to Fig. 1, a kind of cycle control methods using welding resistance to expose file, comprises the following steps:

A, welding resistance exposure file filename after add cycle data;

Such as add the YYWW cycle, welding resistance exposure file designation is 2I00B002A0 (1436) .ts, and 1436 represent 2014 the 36th week; Cycle data can be obtained by software inquiry, after being then added in filename.

B, reading welding resistance operation batch number and job number, and cycle data is checked;

Such as a product only has a job number such as 2I00B002A0, i.e. a part before above-mentioned filename; Wherein first of job number represents the number of plies of substrate, second represents customer number to the 5th, 6th represents same consumer product serial number to the 8th, last Liang Wei representative products version number, file is deposited and is carried out build file folder with job number, needing job number just can find corresponding exposure file when checking exposure file, then going to check whether exposure file exports; A corresponding job number has many at yarn batches, each have batch number such as 14350054E1-00 and 14360056E2-00 in yarn batches correspondence, front four input cycles with regard to representative products, this product drops into 2014 the 35th week and the 36th week respectively, so the cycle in welding resistance exposure file is different, batch number is needed to be because will go to check that cycle in welding resistance exposure file is the need of renewal by first four of comparison batch number.

C, delete used welding resistance exposure file according to job number inspection.

With reference to Fig. 2, be further used as preferred embodiment, described step B comprises following sub-step:

B1, reading welding resistance operation batch number and job number, and all welding resistances in itself and database icsDC are exposed file set up file association; Described database icsDC is a database depositing that all PCB produce fileinfo.

Main method is by the file manipulation command in VBA program:

Scripting.FileSystemObject。This is a file manipulation command library of object, states in VBA program, just may be used for retrieval exposure file and does corresponding judgement to file.

Such as:

Set fs = CreateObject("Scripting.FileSystemObject")

Set sf = fs.GetFolder("\\192.168.224.8\icsDC")

Set fd = sf.Files

Above statement is mainly in order to statement object storehouse and arrange file object, after setting up file association in this way, available For...Each statement goes to inquire about corresponding welding resistance exposure file, then does associative operation, such as, judge whether certain file exists (fs.FileExists) etc.

B2, compare welding resistance exposure file filename after cycle data and welding resistance exposure file suffix in cycle data.

Object is to judge whether that the welding resistance exposure file needing to export the band cycle and the cycle checked in welding resistance exposure file are the need of renewal, concrete grammar is the cycle data (because cycle data is added in top layer and bottom exposure file) extracting suffix in associated documents name, judge whether that ts (representing top layer exposure file) and bs(represents bottom exposure file), the welding resistance exposure file in band cycle is exported if, do not need, if there be ts and bs, extract the cycle data in ts and bs filename again and the cycle data in batch number is compared, judge that cycle data is the need of renewal,

Can refer to following program code to realize:

Public Function TrimPath(sPath As String) As String

Dim i As Integer

i = InStrRev(sPath, ".") + 1

TrimPath = Mid(sPath, i)

End Function

Be extraction document name suffix with superior function, calling in master routine just can the suffix of extraction document name, and then goes to judge.

Public Function TrimPath1(sPath As String) As String

Dim i As Integer, j As Integer

i = InStrRev(sPath, "\") + 1

j = InStrRev(sPath, ".") - 1

TrimPath1 = Mid(sPath, i, j - i + 1)

End Function

Take superior function as extraction document name function, extraction document name is called in master routine, then according to the feature of filename, extracting cycle in principal function, such as Mid (TrimPath1,12,4), 2I00B002A0 (1436) .ts cycle data is latter 4 from the 12nd.

The state of the welding resistance exposure file in B3 and then Query Database icsDC.

1, file is to be output: there is not the job number that will inquire about in document data bank and do not have the file of ts and bs suffix name, represents that file does not export, and prompting related personnel goes to make output file, and this is realized by retrieval job number and comparison file suffixes name;

2, the cycle needs to upgrade: the file that there is ts and bs suffix name, then removes the cycle data in comparison filename and the cycle data in batch number, as difference, then needs the update cycle, and prompting related personnel goes to upgrade output file;

3, cycle data does not have problems: namely there is corresponding welding resistance exposure file and consistent with in batch number of cycle, do not need to do any change.

With reference to Fig. 2, be further used as preferred embodiment, described step C comprises following sub-step:

C1, to check according to job number whether corresponding welding resistance exposure file cycle data occurred;

If C2 occurred, then by corresponding welding resistance exposure file erase.

More than that better enforcement of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art can also make all equivalents or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
