Embodiment 1
[0078] Example one, according to figure 2 As shown, an efficient defect spot inspection method. All products generate batch numbers of product batches in the order of entering the production line. There are multiple inspection stations on the production line. The inspection stations are arranged at intervals between the multiple processes of the production line. There are multiple production equipments in the process;
[0079] Efficient defect sampling method includes the following steps:
[0080] Step S1: Determine the sampling batch according to the mantissa of the product batch number;
[0081] Step S2: Starting from the last product batch tested, the testing station counts all product batches passing through the testing station separately according to the production equipment to obtain the number of interval batches;
[0082] Step S3: After the inspection station completes the last inspection, the interval batch number is compared with the first preset value input by the user;

Embodiment 2
[0106] Example two, according to Figure 4 As shown, in step S6, the following steps are further included:
[0107] Step S61: Before the inspection station starts the next inspection, obtain the ratio of the product batch to be inspected from the completion of the previous process to the current time to the corresponding control time from the previous process to the next process, which is the first ratio , Judge the first ratio to be compared with the second preset value input by the user;
[0108] If the first ratio is less than the second preset value, go to step S62;
[0109] If the first ratio is not less than the second preset value, the detection station abandons the detection and proceeds to step S7;
[0110] In step S62, the inspection station starts the next inspection and returns to step S2.
[0111] Specifically, in this embodiment, since there is a control time between the process and the process, the product must enter the next process within the predetermined control time...
Embodiment 3
[0112] Example three, according to Figure 5 As shown, in step S72, the following steps are further included:
[0113] Step S721: Before the inspection station starts the next inspection, obtain the ratio of the product batch to be inspected from the completion of the previous process to the current time to the corresponding control time from the previous process to the next process, which is the second ratio , Judge the second ratio to compare with the second preset value;
[0114] If the second ratio is less than the second preset value, go to step S722;
[0115] If the second ratio is not less than the second preset value, go to step S723;
[0116] In step S722, the inspection station starts the next inspection and returns to step S2.
[0117] In step S723, the inspection station abandons the inspection and returns to step S71.
[0118] Specifically, in this embodiment, when there are no subsequent random inspection batches of the production equipment, there is also the problem of ma...
