The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The present embodiment comprises to the tracking of laminating machine tightness, to the tracking of laminating machine state of temperature, to the tracking of laminating machine evacuation rate and the tracking to the whole lamination process vacuum state of laminating machine.
As depicted in figs. 1 and 2, the tracking to laminating machine state of temperature.W1 is the temperature curve of thermometer 1, and W2 is the temperature curve ofthermometer 2, and W3 is the temperature curve of thermometer 3, and W4 is the temperature curve of thermometer 4, and W5 is the temperature curve of thermometer 5.From lamination, start to finish to follow the tracks of the laminating machine of working to lamination, the temperature value on each thermometer laminating machine display screen being shown with video recorder is recorded a video, and then video recording data is exported to computer.Temperature value on each thermometer was intercepted to 1 numerical value every 60 seconds, using EXCEL software take and as abscissa, temperature value, as ordinate, draw respectively the Temperature numerical of each thermometer of laminating machine with the coordinate diagram of the variation of remaining lamination time in lamination process remaining time in lamination process, is curve by each coordinate points smooth connection afterwards; Through long-term follow, observe, the temperature value upper and lower limit of the borderline risk state that each thermometer is occurred is recorded, and the temperature value of the upper and lower borderline risk state of the laminating machine that the present embodiment is followed the tracks of is respectively 143.5 ℃ and 136.5 ℃, forever deposits in computer.Then every a period of time, each Temperature numerical of the whole process of this laminating machine is followed the tracks of once as required, according to the method described above curve plotting coordinate diagram.If curve smoothing and displays temperature between 143.5 ℃ and 136.5 ℃, illustrate that laminating machine state of temperature is normal.The curve that thermometer 1 as shown in Figure 1,thermometer 2, thermometer 3, thermometer 4,thermometer 5 are drawn is normal, the curve that thermometer 1 as shown in Figure 2, thermometer 3, thermometer 4,thermometer 5 are drawn is normal, the curve thatthermometer 2 is drawn out occurred upper and lower beat and A point and C point temperature lower than 136.5 ℃, B point temperature is higher than 143.5 ℃, may cause component internal EVA due to fusing in advance cause hungry area phenomenon or not fusing have EVA particle, cause the generation of bubble, the generation of substandard product phenomenon.From temperature feed system and the control system analyzing failure cause of laminating machine thermometer, as fluctuated in certain some temperature appearance, be in most cases that conduction oil is unclean, cause non-uniform temperature, at this moment need to change conduction oil.
As shown in Figure 3, the tracking to laminating machine tightness.After laminating machine under Light Condition is evacuated down to numerical value and can not changes, numerical value is-100KPa left and right, after closing all valves of upper and lower chamber, keep a period of time, by epicoele and cavity of resorption vacuum value that video recorder shows laminating machine display screen, record a video, then video recording data are exported to computer.From the vacuum value of epicoele and cavity of resorption, every 30 seconds, intercept respectively 1 data, use origin software to take the dwell time and draw respectively the vacuum value of laminating machine epicoele and cavity of resorption with the coordinate diagram of the variation of dwell time as abscissa, vacuum value as ordinate, by each coordinate points smooth connection, be straight line afterwards, the slope of calculated line.Through long-term follow, observe, epicoele and cavity of resorption are occurred to the straight line of borderline risk state and its slope record respectively, the laminating machine epicoele that the present embodiment is followed the tracks of is 0.43356 kpa/min, and cavity of resorption is 0.44611 kpa/min, forever deposits in computer.Then every a period of time, this laminating machine tightness is followed the tracks of once as required, draw according to the method described above rectilinear coordinate graph, straight slope < 0.43356 kpa/min that epicoele is drawn, straight slope < 0.44611 kpa/min that cavity of resorption is drawn, illustrates that this laminating machine is working properly.If the straight slope that epicoele is drawn approaches or > 0.43356 kpa/min; the straight slope that cavity of resorption is drawn approaches or > 0.44611 kpa/min; illustrate that the upper and lower chamber work of this laminating machine is tending towards undesired or undesired; each parts of laminating machine sealing system break down; cause laminating machine gas leakage; pressurize ability declines, and the gas row of assembly the inside is unclean, causes the generation of substandard product phenomenon.By the tracking to laminating machine tightness, in time each parts that cause upper and lower chamber straight slope to be tending towards the sealing system of abnormal state or abnormal state are analyzed, find out the reason that will break down, correct in time.As straight slope declines and approaches critical value, maximum possible is that sealing ring has been broken, and at this moment needs to change in time sealing ring.
As shown in Figure 4 and Figure 5, the tracking to laminating machine evacuation rate.To the upper and lower chamber of the laminating machine under duty, from vacuumizing, start to vacuumizing stablely, by epicoele and cavity of resorption vacuum value that video recorder shows laminating machine display screen, record a video, then video recording data are exported to computer.From the vacuum value of epicoele and cavity of resorption, every 1 data of intercepting in 2 seconds, the time of using EXCEL software take to vacuumize is drawn respectively the vacuum value of laminating machine epicoele and cavity of resorption with the curvilinear coordinate figure of the variation in pumpdown time as abscissa, vacuum value as ordinate.Through long-term follow, observe, will vacuumize the longest crash time used to record, the longest crash time of the laminating machine that the present embodiment is followed the tracks of is 90 seconds, forever deposits in computer.Then every a period of time, this laminating machine evacuation rate is followed the tracks of once as required, if start within 90 seconds, to illustrate that laminating machine evacuation rate is normal to vacuumizing epicoele and cavity of resorption time used while stablizing from vacuumizing.If started to vacuumizing while stablizing epicoele and cavity of resorption is around used or over 90 seconds from vacuumizing; as shown in Figure 5; illustrate that this laminating machine vacuumizes state and is tending towards undesired or undesired, laminating machine vacuumizes the undesired meeting of state and causes assembly bubble, produces substandard product phenomenon.By the tracking to laminating machine evacuation rate, in time each parts that cause the state of vacuumizing to be tending towards undesired or abnormal pumped vacuum systems are analyzed, find out the reason that will break down, correct in time; If vacuumize to reach, extending and approach 90 seconds stabilization time, is that vacuum capability has declined, and may be that vavuum pump is aging, need to change, and be likely also vacuum-pumping pipeline gas leakage, at this moment need to check the problem of pipeline, valve.
As shown in Figure 6 and Figure 7, the tracking to the vacuum state of the whole lamination process of laminating machine.Laminating machine under duty is vacuumized and starts to finish to the laminating machine lamination process of uncapping from closing lid, by epicoele and cavity of resorption vacuum value that video recorder shows laminating machine display screen, record a video, then video recording data are exported to computer.1 data of intercepting in every 60 seconds from the vacuum value of epicoele and cavity of resorption respectively, are used EXCEL software to take the vacuum value of drawing respectively laminating machine epicoele and cavity of resorption remaining time as abscissa, vacuum value as ordinate of lamination process with the curvilinear coordinate figure of variation that takes out the remaining time of lamination process.If the picture shape of drawing in the vacuum time used within the dangerous crash time, as 90 seconds, tend to be steady later, lamination process for the first time and for the second time lamination process vacuum value with straight line, steadily decline, in lamination process vacuum value for the third time, tend to be steady, illustrate that the whole lamination process vacuum state of laminating machine is normal.If the picture shape of drawing is not above normal condition, illustrate that the whole lamination process vacuum state of laminating machine is abnormal, illustrate that laminating machine vacuum is out of joint, may cause assembly bubble, produce substandard product phenomenon.By the tracking to the vacuum state of the whole lamination process of laminating machine, in time each parts that cause laminating machine vacuum to be tending towards undesired or abnormal pumped vacuum systems are analyzed, find out the reason that will break down, correct in time.If vacuum, for the first time lamination process, for the second time lamination process and for the third time in lamination process any one or more snippets shape go wrong, maximum possible be magnetic valve broken or laminating machine computer program out of joint, after computer program goes wrong, may be by the valve open that should not open, the valve closing that should not close, at this moment needs to check magnetic valve and laminating machine computer program.
Certainly, above-described embodiment is only preferred and exemplary, the present invention also has other multiple example, without prejudice to the present invention's spirit and essence in the situation that, those of ordinary skill in the art can make corresponding change and distortion according to description of the invention, as by each thermometer, any number of seconds in second intercepts 1 temperature value every 30-80, use the Temperature numerical of other each thermometer of Software on Drawing with the coordinate diagram of the variation of remaining lamination time in lamination process; As the vacuum value from 1 of any number of seconds intercepting second every 20-40 of epicoele and cavity of resorption, use the vacuum value of other Software on Drawing laminating machine epicoele and cavity of resorption with the coordinate diagram of the variation of dwell time; As from epicoele and cavity of resorption every 2-5 1 vacuum value of number of seconds intercepting arbitrarily second, use the vacuum value of other Software on Drawing laminating machine epicoele and cavity of resorption with the curvilinear coordinate figure of the variation in pumpdown time; As from epicoele and the every 30-80 of the cavity of resorption vacuum value of 1 of number of seconds intercepting arbitrarily second, the vacuum value of using other Software on Drawing laminating machine epicoele and cavity of resorption is with the curvilinear coordinate figure etc. of variation that takes out the remaining time of lamination process.These corresponding changes and distortion all should belong in the protection domain of the claims in the present invention.
