Fig. 2 is a flow chart illustrating an offline membrane defect rejection method according to another embodiment of the present application.
As shown in fig. 2, the method for offline removing a defect of a diaphragm of this embodiment includes the following steps:
100, acquiring diaphragm defect information, wherein the diaphragm defect information comprises a defect meter number detection list, defect types and the like;

Fig. 3 schematically shows a flow chart of acquiring a defect meter-number rejection list in an offline rejection method for a diaphragm defect according to an embodiment of the present application.
In some embodiments, as shown in fig. 3, step 101, obtaining a defective meter number culling list, includes the following steps:
1010, marking the detection end position as a starting point;
1011, acquiring a defect meter number detection list, wherein the defect meter number detection list is a set of all defect positions;
and 1012, calculating and counting the distance between each defect position in the defect meter number detection list and the starting point to obtain a defect meter number elimination list.
It should be noted that the defect meter number detection list in step 1011 is obtained at the online detection stage of the splitting machine, and in the detection stage, the detection start position and the detection end position are recorded, and all the defect positions in the detection process are recorded and collected as the defect meter number detection list.
In the step 1012, the defect meter number elimination list is that in the elimination stage of the triaxial rewinding machine, the detection ending position is marked as a starting point, the distance from each defect position to the starting point is calculated and is used as a new defect position, and all new defect positions are counted, so that a defect meter number elimination list opposite to the defect meter number detection list can be obtained.
A schematic diagram of the slitter detection sequence and the rewinder reject sequence is shown in fig. 4.
As shown in figure 4, the detection sequence of the slitter is opposite to the removal sequence of the rewinder, the arrow direction in figure 4 is the detection direction of the slitter, the detection sequence of the slitter in figure 4 is 0m-6000m, the initial adhesive tape position is 5998m, the adhesive tape splicing position is 4000m, and the defect position is 2000 m. The rewinding machine rejection sequence is 0m (6000 m of the slitting machine detection sequence) to 6000m (0 m of the slitting machine detection sequence), the initial adhesive tape position 5998m on the slitting machine detection sequence in the figure 4 is converted into the initial adhesive tape position 2m of the rewinding machine rejection sequence, the splicing adhesive tape position 4000m on the slitting machine detection sequence is converted into the splicing adhesive tape position 2000m of the rewinding machine rejection sequence, and the defect position is converted into 4000 m. And the types of the encoders 2 selected in the detection stage of the splitting machine and the extraction stage of the rewinding machine are different, and errors may exist when the defect meter number detection list is converted into the defect meter number elimination list. When the roller of the rewinder rotates to drive the membrane to move, errors caused by stretching exist. When the rewinder stops, the number of the encoder points is counted, namely the number of the actual meters exceeds the number of the meters at the defect position, and the diaphragm is lost; when the rewinder stops, the number of the encoder points is counted, namely the number of the actual meters is smaller than the number of the meters at the defect position, the number of the defects is required to be found again, and the actual position of the defect of the diaphragm is required to be eliminated. Due to the reasons, the number of meters of the diaphragm in the detection stage and the rejection stage of the splitting machine is deviated, and the rejection of the diaphragm defects is inaccurate. Therefore, in order to improve the defect removal accuracy, the number of the defective meters of the diaphragm in the removal stage of the rewinder needs to be corrected.
Fig. 5 schematically shows a total flow chart of calculation of the meter number correction factor in an offline membrane defect rejection method according to an embodiment of the present application.
In some embodiments, as shown in fig. 5, step 102, obtaining the meter number correction factor includes the following steps:
1020, acquiring and marking a first tape detection position as a starting point, wherein the first tape detection position is acquired from a defect meter number detection list;
1021, acquiring a second adhesive tape detection position in the defect meter number detection list;
1022, acquiring a current position of a second adhesive tape corresponding to the detection position of the second adhesive tape, wherein the current position of the second adhesive tape is a position of the second adhesive tape passing through the color mark sensor 3 in the running process of the triaxial rewinding machine;
1023, calculating a meter number correction coefficient according to the starting point, the second adhesive tape detection position and the current position of the second adhesive tape.
It should be noted that the first tape detection position is detected in the slitter detection stage and is used as a starting point, that is, the current position (starting point) of the first tape in the rewinding machine removing stage is the same as the first tape detection position, the second tape detection position is detected in the slitter detection stage, and the current position of the second tape is the position of the second tape passing through the color mark sensor 3 in the rewinding machine removing stage.
It should be noted that, the first adhesive tape and the second adhesive tape can be adhesive tapes with distinct colors, such as blue glue or red glue. The first adhesive tape detection position is a position before the detection of the slitting machine in the detection stage is about to end, the first adhesive tape is used as a starting adhesive tape in the rejection stage of the triaxial rewinding machine, and the position of the starting adhesive tape is not changed. For example, in the cut detection stage, the tape is applied, i.e., the starting tape, typically at a position about 1m from the end of the separator. The second adhesive tape detection position is an adhesive tape for splicing which is stuck when the next roll of diaphragm is connected due to the requirement of diaphragm production in the detection process of the detection stage of the cutting machine and the insufficient length of the diaphragm, and the position of the adhesive tape for splicing has errors due to the influence of interference factors in the detection stage and the rejection stage. For example, the adhesive is applied, i.e. taped, at a distance of about 2000m from the end of the membrane. The starting adhesive tape position is a position at which the detection of the defect of the diaphragm is about to end, but the starting adhesive tape position cannot be a position at which the detection of the defect of the diaphragm is ended, and the tape splicing adhesive tape position can be selected by a person skilled in the art according to production needs, and the application does not specifically limit the position. Therefore, the meter number correction coefficient can be calculated through the initial adhesive tape position and two different positions of the splicing adhesive tape in the detection stage and the elimination stage.
In addition, in order to ensure that the color mark sensor 3 on the triaxial rewinding machine can clearly scan the position of the initial adhesive tape, the initial adhesive tape adhered in the slitting detection stage needs to be manually cut, and then the initial adhesive tape is adhered again at the same position when the rewinding machine is removed, and the triaxial rewinding machine is opened until the color mark sensor 3 scans the initial adhesive tape to complete the automatic calibration process.
In some embodiments, as shown in fig. 5, the step 1023 of calculating the meter number correction factor according to the starting point, the second tape detection position and the second tape current position includes the following steps:
10230, calculating a first distance from the second adhesive tape detection position to the starting point;
10231, calculating a second distance from the current position of the second adhesive tape to the starting point;
10232, and calculating a meter number correction coefficient according to the first distance and the second distance.
In some embodiments, in step 1023, a meter correction factor is calculated based on the starting point, the second tape detection position, and the second tape current position, the specific calculation formula being as follows:
wherein K represents a meter number correction coefficient, A represents a starting point, B represents a second adhesive tape detection position, C represents a second adhesive tape current position, B-A represents a first distance, and C-A represents a second distance.
It should be noted that, because the membrane is stretched, the detection position of the second adhesive tape is obtained in the detection stage of the splitting machine, the current position of the second adhesive tape is obtained in the removal stage of the rewinding machine, for example, the detection position of the first adhesive tape is 2000m, and the current position of the second adhesive tape is 2100m after the membrane is stretched in the removal stage of the rewinding machine.
In addition, since the adhesive tape also belongs to a kind of membrane defect, in the rewinding machine rejecting stage, the actual positions of the first adhesive tape and the second adhesive tape also need to be rejected.
Fig. 6 schematically shows a flowchart for calculating the number of currently-rejected defective meters in the method for offline rejecting a diaphragm defect according to an embodiment of the present application.
In some embodiments, as shown in fig. 6, step 103, obtaining the number of defective meters currently removed includes the following steps;
1030, acquiring the number of the current encoder points, and recording and transmitting the number of the current encoder points to the industrial personal computer 4 through the encoder 2;
1031, according to the defect meter number removing list, obtaining the next defect removing position adjacent to the current encoder point number;
1032, calculating the number of theoretical encoders according to the current number of encoders, the starting point and the meter number correction coefficient;
1033, calculating the number of theoretically eliminated defect meters according to the next defect elimination position and the number of theoretically encoder points;
1034, according to the theoretical number of the removed defective meters and the meter number correction coefficient, calculating the current number of the removed defective meters.
It should be noted that, in the above solution, the number of current encoder points represents the actual moving distance from the movement of the three-axis rewinding machine to the current position.
The number of the theoretical encoder points represents the distance that the triaxial rewinding machine recorded in the industrial personal computer 4 theoretically needs to move to the current position under the ideal condition, namely, under the condition that the diaphragm is not stretched.
The number of the theoretical removed defect meters indicates the distance required for the three-axis rewinding machine to move from the current position, namely the point position of the theoretical encoder to the next defect removing position under the ideal condition, namely the condition that the diaphragm is not stretched.
The number of the current defect removed meters indicates that the distance required for moving the triaxial rewinding machine from the current position, namely the position of the number of the current encoder points to the next defect removal position needs to be removed under the condition that interference factors (including stretching and the like) actually exist.
In some embodiments, step 1032 calculates the theoretical encoder point according to the current encoder point, the starting point and the meter number correction coefficient, and the specific formula is as follows:
RR＝(R-A)＊K，
wherein RR represents the number of theoretical encoder points, R represents the number of current encoder points, A represents the starting point, and K represents the meter number correction coefficient.
In some embodiments, step 1033, the theoretical defect rejection meter number is calculated according to the next defect rejection position and the theoretical encoder point number, and the specific formula is as follows:
RD＝D-RR，
wherein RD represents the number of theoretical defect removal meters, D represents the next defect removal position, and RR represents the number of theoretical encoder points.
In some embodiments, step 1034, the current number of rejected defective meters is calculated according to the theoretical number of rejected defective meters and the meter number correction coefficient, and the specific formula is as follows:
TD＝RD/K，
wherein TD represents the current defect removing meter number, RD represents the theoretical defect removing meter number, and K represents the meter number correction coefficient.
Fig. 7 shows a schematic diagram of the information of the number of meters of the diaphragm in three cases, namely, slitting, rejecting and actually performing in the embodiment of the present application.
As shown in FIG. 7, the inspection sequence of the separator during slitting was 0m to 6000m, the first defect inspection position was 2000m, and the second defect inspection position was 3700 m. The rewinding sequence of the membranes during removal is opposite to the detection sequence of the membranes during slitting, the defect positions also need to be recalculated, the rewinding sequence of the membranes is 0m (6000 m during slitting) to 6000m (0 m during slitting), the first defect removal position is 2300m (the second defect detection position), and the second defect removal position is 4000m (the first defect detection position). In fact, due to the influence of interference factors including stretching of the diaphragm, the actual number of meters of the diaphragm deviates from the theoretical number of meters of the diaphragm during rejection, and therefore, the current rejection defect number of meters TD (unknown) between the current encoder point number R (known) and the next defect rejection position D (unknown) after stretching of the diaphragm needs to be calculated through the formula. For example, the current number of the encoder points is 200m, the next defect position closest to the current number of the encoder points is 2000m, and at this time, 1800m needs to be moved to the next defect position, but in reality, the membrane is stretched, and the triaxial rewinding machine needs to be moved by 1800/0.9 (for example, the meter number correction factor) to 2000m, so that the next defect position of the membrane after stretching may be 2200m, rather than 2000 m. The specific numerical values are exemplary data provided for more clearly illustrating the scheme of the present application, but are not unique data, so that the specific numerical values in the examples do not substantially affect the technical scheme of the present application, and the present application does not limit the specific numerical values at all.
