Example 1:
referring to fig. 1, a flowchart of a workshop intelligent management method based on digitization according to an embodiment of the invention is shown. In this embodiment, the workshop intelligent management method based on digitization includes:
s1, extracting a current assembly working section from a pre-constructed digital working section model, and identifying a lower assembly working section of the current assembly working section.
The digital section model is a digital model for displaying the positions of each section and each team position in the section on the workshop production line. The current assembly section is one section in a factory workshop production line, for example: the sections in the air conditioner production plant can be divided into a part installation section, a product welding section, a line connection section, a product assembling section, a product packaging section and the like. The assembled product is a semi-finished product which is already finished in the current assembly section, for example: when the front assembly working section is a product welding working section, the assembled product refers to the welded product, and the product is waited to be transported to the next working section of the product welding working section for further assembly processing.
It will be appreciated that when the product order delivery time is received, a large schedule time and a small schedule time need to be set according to the time characteristics of each section, for example: when the product order is mold processing, the large schedule time may be a cut-off time of mold design, a cut-off time of inner film material purchase, a cut-off time of mold frame material purchase, a cut-off time of component processing, a mold frame processing cut-off time, a mold loading cut-off time, a mold testing cut-off time, etc., and when the large schedule time is a mold frame processing cut-off time, the small schedule time may be: the die carrier rough machining cut-off time, the die carrier finish machining cut-off time and the like. And determining the duration of each processing section through the size schedule time.
Further, the lower assembly section refers to a next stage section of the current assembly section, for example: the current assembly working section is a product welding working section, wiring is needed after welding is finished, and the lower assembly working section of the product welding working section is a line connection working section.
S2, sequentially calculating the product assembly speed of each assembly team in the lower assembly working section and the quantity of the remaining products to be assembled.
As will be appreciated, the assembly team refers to the individual assembly team in the subordinate assembly station, such as: in order to improve the production efficiency, the product welding sections can be further divided into a first welding group, a second welding group and a third welding group. The product assembly speed refers to the amount of product assembly completed per unit time per assembly team, for example: the first welding team can weld 5 air conditioners in 1 minute, and the product assembly speed of the first welding team is 5 per minute.
It should be appreciated that the remaining amount of product to be assembled refers to the amount of product that arrives at the assembly team and has not yet been assembled.
In the embodiment of the present invention, the calculating, in order, the product assembly speed and the remaining product to be assembled of each assembly team in the lower assembly working section includes:
Acquiring the real-time assembly speed of each assembly team in the lower assembly working section, and drawing an assembly speed-time graph according to the real-time assembly speed;
acquiring current assembly time, and extracting the product assembly speed from the assembly speed-time curve graph according to the current assembly time;
and obtaining the original product quantity to be assembled of the assembly team, and calculating the residual product quantity to be assembled of the assembly team according to the original product quantity to be assembled and the assembly speed-time curve chart.
It is understood that the assembly speed-time graph refers to constructing a two-dimensional coordinate system with time as the abscissa scale value and assembly speed as the ordinate scale value. The original amount of the product to be assembled refers to the amount of the semi-finished products that need to be assembled after the assembly team performs product transfer last time, for example: the number of semi-finished products waiting for welding, which are transferred last time by the first welding team, is 100, and 10 products remain at the moment, and the number of the original products to be assembled is 110. The remaining amount of product to be assembled refers to the number of semi-finished products that the assembly team needs to assemble at the current assembly time, for example: the original amount of the product to be assembled is 110, the real-time assembling speed is consistent and maintained at 10 pieces/min, and after 5 minutes, the amount of the remaining product to be assembled is 60 pieces.
In the embodiment of the present invention, the calculating the remaining product to be assembled of the assembly team according to the original product to be assembled and the assembly speed-time graph includes:
acquiring original assembly time, and intercepting a current assembly period in the assembly speed-time curve chart according to the original assembly time and the current assembly time;
extracting an assembly speed curve corresponding to the current assembly period from the assembly speed-time curve;
calculating the current accumulated assembly quantity by utilizing a pre-constructed current assembly integral formula according to the current assembly period and the assembly speed curve;
and calculating the quantity of the remaining products to be assembled according to the original quantity of the products to be assembled and the current accumulated assembled quantity.
It is understood that the initial assembly time is the time for counting the amount of the product to be assembled, and the current assembly time is a time period between the initial assembly time and the current assembly time.
In the embodiment of the present invention, the current assembly integral formula is as follows:
wherein, the liquid crystal display device comprises a liquid crystal display device,representing the current accumulated fit-up amount of the ith fit-up team during the original fit-up time and the current fit-up time, t iy Representing the original assembly time, t, of the ith assembly team id Representing the current assembly time, v, of the ith assembly team i And the assembly speed curve value of the ith assembly team between the original assembly time and the current assembly time is represented.
It can be explained that when the assembly speed curve represents the assembly speed and the abscissa represents time, the projected area (integral) of the curve on the abscissa is the current accumulated assembly amount.
S3, calculating the assembly residual time length of the assembly team according to the product assembly speed and the residual product quantity to be assembled.
It is understood that the assembly remaining time period refers to a time period during which the assembly team completes the assembly of the remaining amount of product to be assembled.
In the embodiment of the present invention, the calculating the assembly remaining time of the assembly team according to the product assembly speed and the remaining product to be assembled includes:
extracting a current assembly speed corresponding to the current assembly time from the assembly speed-time graph;
extracting a current curve slope of the assembly speed-time curve graph at a current assembly time point;
judging whether the slope of the current curve is greater than zero;
if the current curve slope is greater than zero, extending an assembly speed-time curve in the assembly speed-time curve graph according to the curve slope to obtain an assembly increment-time curve segment;
Calculating the predicted time length of the accumulated assembling quantity corresponding to the assembling acceleration-time curve section, which is equal to the quantity of the residual product to be assembled, and taking the predicted time length as the assembling residual time length;
if the slope of the current curve is not greater than zero, extending an assembly speed-time curve in the assembly speed-time curve graph according to the current assembly speed to obtain an assembly constant speed-time curve segment;
calculating the predicted time length of the accumulated assembling quantity corresponding to the assembling constant speed-time curve section, which is equal to the quantity of the residual product to be assembled, and taking the predicted time length as the assembling residual time length.
It should be appreciated that when the current curve slope is greater than zero, indicating that the current assembly speed of the assembly team is the up-phase, the assembly speed of the assembly team in the future may be predicted to be an increment that keeps the slope unchanged, i.e., the assembly speed curve is a ray having a slope that is the current curve slope in the future. And when the slope of the current curve is equal to zero, representing that the current assembly speed of the assembly team is in a constant stage, and when the slope of the current curve is smaller than zero, representing that the current assembly speed of the assembly team is in a descending stage, wherein in order to ensure that the assembly team does not have the condition of no semi-product assembly in the future, the current assembly speed is taken as the future assembly speed.
It can be appreciated that when the assembly team is a mold finishing team, the mold finishing completion time can be intelligently calculated according to the mold processing speed of the mold finishing team and the remaining time length of the remaining waiting processing amount for the mold finishing process.
Further, for example: the slope of the current curve is 2, and the current assembly speed is 10 pieces/min, so that the assembly speed after one minute is 12 pieces/min, and the assembly speed after two minutes is 14 pieces/min; the slope of the current curve is 0, and the current assembly speed is 10 pieces/min, so that the assembly speed after one minute is 10 pieces/min, and the assembly speed after two minutes is still 10 pieces/min; the current slope of the curve is-1, and the current assembly speed is 10 pieces/min, the assembly speed after one minute is 9 pieces/min, the assembly speed after two minutes is 8 pieces/min, and so on.
In the embodiment of the present invention, the calculating the predicted time length for the accumulated assembling quantity corresponding to the assembling acceleration-time curve segment to be equal to the remaining product quantity to be assembled includes:
calculating a fitting amount-time function according to the slope of the current curve by using a pre-constructed fitting amount prediction formula;
Extracting the speed-increasing prediction time of which the function quantity of the assembly quantity-time function is equal to the quantity of the residual product to be assembled;
it will be appreciated that the fit-time function represents a value of the change in fit of the fit team over time. The speed-up prediction time refers to a time point at which the function quantity of the assembly quantity-time function is equal to the quantity of the remaining product to be assembled.
And calculating the predicted time length according to the current assembly time and the speed-increasing predicted time.
Further, the predicted time period indicates a time period during which the remaining amount of the product to be assembled is completely assembled at the predicted assembly speed. And subtracting the current assembly time and the speed-increasing prediction time when the current assembly time and the speed-increasing prediction time are obtained, so as to obtain the prediction duration.
In the embodiment of the invention, the assembly quantity prediction formula is as follows:
wherein s is zy Representing the fit-time functionFunction value t of (2) if Represents the speed-up prediction time, V id Representing the current assembly speed, k representing the current curve slope, and t representing time.
Further, the same principle as the calculation of the current accumulated assembly amount, the current assembly speed plus the product of the slope of the current curve and time may represent the value of the assembly speed at the time t. And integrating to obtain the assembly quantity, and obtaining the predicted time length when the assembly quantity calculated by accumulated prediction is equal to the quantity of the remaining products to be assembled.
S4, acquiring the product transfer time length of the assembly team, and calculating the assembly net time length of the assembly team according to the assembly residual time length and the product transfer time length by utilizing a pre-constructed assembly net time length formula.
Further, since the distances of different assembly teams from the current assembly station are different, for example: in carrying out the transportation on the line, the distances between different assembly teams and the transport starting position of the current assembly working section are different, and the general transport speed is constant, so that the transport time length needs to be subtracted.
In detail, the assembly net remaining time formula is as follows:
t ij ＝t is -t iz
wherein; t is t ij Indicating the net remaining length of assembly, t, for the ith assembly team is Indicating the remaining assembly time period, t, of the ith assembly team iz Indicating the product transfer duration of the ith assembly team.
In the embodiment of the present invention, the obtaining the product transferring duration of the assembly team includes:
acquiring a transfer starting position of the assembled product and a transfer receiving position of the assembly team;
calculating the transfer distance of the assembly team according to the transfer starting position and the transfer receiving position;
and acquiring the transfer speed of the current assembly working section, and calculating the product transfer duration according to the transfer speed and the transfer distance.
S5, sorting the transfer priorities of the assembly groups according to the assembly net residual time of each assembly group to obtain a transfer group sequence.
The order of the transfer team may be interpreted to indicate a priority order of the assembly transfer required, the earlier the ordering, the higher the priority of the diversion.
In the embodiment of the present invention, the sorting the transfer priorities of the assembly teams according to the assembly net remaining time of each assembly teams to obtain a transfer teams sequence includes:
sequencing the assembly net surplus time length of each assembly team according to the sequence from small to large to obtain a net surplus time length sequence;
and sequencing the assembly groups according to the positions of each assembly group in the lower assembly working section in the net surplus time duration sequence to obtain the transfer group sequence.
It can be appreciated that during the process of transferring the semi-finished product to the next assembly section, each assembly team of the next assembly section can be ordered in processing capacity, and the semi-finished product is preferentially transported to the assembly team with larger residual assembly capacity (i.e. the assembly team has smaller assembly net residual time), and when the adjacent materials in each assembly team are completely assembled, automatic intelligent alarm is carried out to remind of timely transfer.
