- line information shown in FIG. 14 is read from the line information recording unit 62 (S40), and it is determined whether a channel tag exists in the read line information (S41).
- the data of the workpiece 36 is arranged in order of examination time (S42).
- the data of the work 36 is arranged based on the content of the channel tag (S43).
- the content of the alignment tag in the channel tag of the inspection device 1 tag is “1CH, 2CH, 3CH”. Therefore, the data of the inspection file of 1 CH ((a) in FIG. 10), the data of the inspection file of 2 CH ((b) of FIG. 10), and the data of the inspection file of 3 CH ((c) in FIG. 10) are selected in order By arranging them and repeating this, it is possible to arrange the data in the order of workpiece input ((b) in FIG. 11).
- the arranged data is rearranged based on the inversion tag (S45). Thereafter, the data combining process is finished, and the original routine is returned to.
- the number of works in the reverse tag of the inspection device 2 tag is three. Therefore, the data of the inspection file of the inspection machine 2 (FIG. 13) can be arranged in the data of the work input order by reversing (reversed) the order of the data of the three works and repeating this.
- FIG. 16 shows an example of the contents of the examination file created by the examination device 35 shown in FIG. 12 and acquired by the data collection device 11 in the form of a table
- FIG. 16 and FIG. 17 An example of the contents of the characteristic value table and the NG table recorded in the recording unit 63 is shown in a table format.
- the items in each column are, in order from the left, a work number (work ID), an inspection order, measurement items 1 to 6, an inspection result, a measurement time, and a channel number.
- the characteristic value table is for storing characteristic values. As shown in (a) of FIG. 17, all data stored in the characteristic value table is numerical data. Therefore, by using the characteristic value table recorded in the inspection DB recording unit 63, data analysis can be performed by the PC 14. For example, the data of the above-mentioned characteristic value table is read every hour, and the transition of the characteristic value is examined by calculating the average value and the dispersion value for each channel, or the record including null is counted to calculate the yield. By doing this, the status of the inspection machine can be checked.
- the types of numerical values (integers, natural numbers, single precision, double precision, etc.) of each item in the specific value table are the same as the types of numerical values of corresponding items in the examination file shown in FIG.
- the NG table character strings of inspection error and inspection abnormality are stored.
- the data stored in the NG table is numerical data only for the work ID, and the others are character string data.
- the character string when the inspection file includes a character string such as an inspection error or an inspection abnormality, the character string is converted to null and stored in the characteristic value table.
- a character string such as an inspection error or an inspection abnormality
- the character string is converted to null and stored in the characteristic value table.
- the characteristic value table shown in (a) of FIG. 17 the character string is converted to null.
- the PC 14 can analyze an inspection error, an inspection abnormality, and the like.

- By displaying the tabulation results in a table and a graph it is possible to confirm the tendency of inspection errors (increase, decrease, etc.), and to confirm the condition of equipment.
- the NG table is created, the tallying and the confirmation become possible.
- the additional information such as the order information is stored in the characteristic value table, and therefore, it is possible to count in the additional information unit.
- the recording unit 41 further includes an allowable range recording unit for storing the allowable range (upper limit and lower limit) of the inspection data
- the data changing unit 51 further includes the inspection data in the inspection file from the inspection file recording unit 60 described above. If out of the allowable range, a string indicating abnormality may be added to the NG file. In this case, the character string indicating the abnormality is added to the NG table in association with the position where the inspection data is added to the characteristic value table. Therefore, by referring to the NG table, it is possible to analyze an inspection error and an inspection abnormality.

For this reason, as shown in FIG. 18, data of 3 CH exists at the inspection time “9:00:00” which is the start time of the inspection, but data of 1 CH ⁇ 2 CH does not exist. Also in this case, data indicating no work may be inserted as data of 1CH ⁇ 2CH at the inspection time “9:00:00”.
- the inspection unit 330 of 3CH inspects the workpiece 6, and the inspection unit 330 of 2CH inspects the workpiece 2, but no workpiece exists in the inspection unit 330 of 1CH. For this reason, as shown in FIG. 18, at the inspection time “9:00:03” which is the next inspection time, data of 2CH ⁇ 3CH is present, but data of 1CH is not present. Also in this case, data indicating no work may be inserted as data of 1 CH at the inspection time “9:00:03”.
- FIG. 19 shows, in the form of a table, an arrangement of workpiece numbers to be inspected by the inspection device 2 and inspection times.
- (A) of the figure is actual data. If three pieces of this data are rearranged, it becomes the work insertion order as shown in FIG. Next, the inspection times are changed three by three so that the order of the inspection times is the order in which the work is input. As a result, as shown in (c) of the figure, it becomes data in which the measurement times are arranged in the order in which the work is input.
- any one of the three workpieces placed on the inspection table 38 is inspected by the inspection unit 330 of 3CH, and another one is inspected by the inspection unit 330 of 2CH. And the remaining one is inspected by the inspection unit 330 of 1 CH, and the inspection by the inspection machine 1 is completed.
- the data combining unit 52 After arranging the inspection data for each work 36 in a predetermined order, the data combining unit 52 also arranges the measurement times in the characteristic value table in order by rearranging the measurement times for each work 36 in the early order.
