Detailed Implementation

[0053] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0054] This invention provides a coating substrate lamination correction control system for correcting the lateral position of a first substrate 1 and a second substrate 2 laminated by a laminator. The structure of the laminator is shown in the attached figure. Figure 4 As shown, this is to ensure that the reference positions of the second substrate 2 and the first substrate 1 coincide in real time. See also Figure 2 In the substrate lamination process, the first substrate 11 is coated and dried, and then laminated with the second substrate 2 by the first tension roller 6. Finally, it is wound up by other tension components and the winding mechanism. The second substrate 2 is laminated with the first substrate 1 by the unwinding mechanism, the first correction mechanism 5, the first tension roller 7, the third tension roller 8, and the fourth tension roller 9.

[0055] See Figure 1 The correction control system includes a sensing module, a control module, and a correction module.

[0056] The sensing module is used to monitor the first and second substrates in real time as they move with the rollers to determine the real-time lateral position data before lamination. The real-time lateral data includes the real-time lateral data of the first substrate and the real-time lateral data of the second substrate.

[0057] The control module is used to calculate the error between the real-time lateral position data and the preset reference position component, and to determine the correction distance;

[0058] The correction module adjusts the lateral position of the second substrate according to the correction distance, so that the reference positions of the second substrate and the first substrate coincide. The sensing module can be a position sensor, preferably a photoelectric sensor. The reference position can be the center position or the edge position, selected according to requirements.

[0059] The principle of the above technical solution is as follows:

[0060] The error amount of the transverse position of the first substrate 1 and the second substrate 2 detected by the sensing module from the reference position determines the correction distance before the substrates are compounded, and the position of the second substrate 2 is corrected by the correction device to ensure that the reference positions of the second substrate 2 and the first substrate 1 coincide in real time. Since the first substrate 1 at the outlet of the oven is in an unstable state, when the transverse position of the first substrate 1 at the outlet of the oven changes, the transverse position of the second substrate 2 is adjusted by the correction device, so that the second substrate 2 has a following relationship, to realize the coincidence of the reference positions of the two substrates, avoid the tension effect of the correction process on the first substrate 1, and reduce the generation of wrinkles. When the position of the first substrate 1 or the second substrate 2 deviates, only the position of the second substrate 2 is adjusted, which can prevent the product quality from being reduced due to the unstable characteristics of the first substrate 1 at the outlet of the oven. The present application not only corrects the first substrate 1 in the oven of the two-in-one compounding machine, but also can be used for the correction of long-path substrates, and removes the process correction, and a terminal correction solves all the centering problems. In the control principle, A+B=0 is followed, wherein A is the instantaneous position error value of the first substrate, and B is the cumulative movement value of the second substrate reference position.

[0061] The beneficial effects of the above technical solution are:

[0062] Because the substrate in the prior art is in a high-temperature and easy-to-stretch state, it is easy to deform and form wrinkles, and after using the device of the present application, the correction distance is obtained by the sensing device, the influence of high temperature is not considered during correction, then the reference positions of the two substrates are coincided, the tension effect is avoided, the easy-to-stretch state is easy to handle, and finally, a set of system can control the correction treatment in the compounding steps of multiple substrates.

[0063] In one embodiment, the sensing module includes a first position sensor 3 and a second position sensor 4, the first position sensor 3 is arranged at a position close to the outlet of the oven, and is used to collect the transverse position of the first substrate when the first substrate moves with the first tension roller 6. The second position sensor 4 is located at a position downstream of the unwinding device, and is used to collect the transverse position of the second substrate 2 between the correction device of the compounding machine and the first tension roller 7.

[0064] The principle and beneficial effects of the above technical solution are:

[0065] The first position sensor 3 and the second position sensor 4 can record the transverse position information of the detected substrate and realize real-time communication. The zero position of the first position sensor 3 and the second position sensor 4 can be compensated and defined according to the necessary interface operation of the equipment installation error.

[0066] In one embodiment, the control module comprises:

[0067] The judging unit is configured to judge whether the lateral position sensed by the first position sensor 3 and the second position sensor 4 coincides with the reference position respectively, and to confirm whether the error is within the preset range when the lateral position does not coincide with the reference position;

[0068] The calculating unit is configured to calculate the correction distance when the error is within the preset range, and the calculation formula is C = A instant - B cumulative, wherein A instant is the current value of the first position sensor in one collection period, B cumulative is the cumulative value of the deviation of the second position sensor from the reference position before the collection period, and C is the correction distance; the preset range of the correction distance calculated according to the error is A < R, wherein R is the maximum allowable error of the first position, which can be set and adjusted;

[0069] The instruction generating unit is configured to generate the control instruction according to the correction distance; wherein,

[0070] The control instruction comprises a correction total amount instruction, a direction control instruction, a speed adjustment instruction and an acceleration adjustment instruction.

[0071] The principle and beneficial effects of the above technical solution are as follows:

[0072] participate Figure 3 C1 represents the center position of the first substrate 1, C2 represents the center position of the second substrate 2, and CO represents the theoretical center of the substrate. The first position sensor 3 detects the deviation of C1 from CO, and C1 is positive when it is to the left of CO and negative when it is to the right of CO. The second position sensor 4 detects the deviation of C2 from CO, and C2 is positive when it is to the left of CO and negative when it is to the right of C2. When C1, C2 and CO coincide, it indicates that the first substrate 1 and the second substrate 2 are both at the theoretical zero position, and the correction device does not work. When C1, C2 and CO do not coincide and the error is within the preset range, it indicates that at least one of the first substrate 1 and the second substrate 2 is not at the theoretical zero position, and the correction device is controlled to work, and the position of the second substrate 2 is adjusted according to the position of the first substrate 1. When the deviation of C1 from CO is greater than a specified value, it indicates that the first substrate 1 is in an abnormal state, and only the correction of the second substrate 2 is completed.

[0073] In one embodiment, the system further comprises an alarm module, which is configured to send an indication signal when the error exceeds the preset range; wherein,

[0074] The indication signal is generated by the following steps:

[0075] The reference detection signal and the lateral detection signal are constructed based on the Doppler signal plane; wherein,

[0076] The reference detection signal is used to generate a reference line according to the detection plane, and the reference line is configured to be a deviation correction response;

[0077] According to the roll body dimension parameter of the transverse detection signal, a training array at different moments is obtained;

[0078] The training array is added to the contrast process of the reference detection signal, and a to-be-transmitted signal for deviation correction detection is generated; wherein,

[0079] The to-be-transmitted signal appears when the error amount exceeds the preset range (appears when A≥R).

[0080] The principle and beneficial effects of the above technical solution are:

[0081] When the error amount exceeds the threshold value, it indicates that a fault has occurred in the compound machine, so the alarm module determines the danger level according to the error amount, and when the danger level is high, an alarm instruction is immediately sent to the alarm to notify the user in the form of sound or light. Process; for the low danger level, display on the touch screen to inform the user to process, reduce the risk of compound machine downtime.

[0082] In one embodiment,

[0083] The alarm module is specifically used for:

[0084] According to the error amount, determine the danger level of the current compound machine working state;

[0085] When the danger level of the current compound machine working state meets the preset level requirement, the alarm information is displayed in the form of a pop-up window (the information displayed in the pop-up window includes information for judgment and adjustment according to the working state, including speed reduction, slow acceleration, slow deceleration, low-speed operation, shutdown, etc.); otherwise, send an alarm instruction to the alarm;

[0086] Real-time receive confirmation information, if the confirmation information is received within a preset time period, then close the pop-up window and end the alarm, otherwise send an alarm instruction to the alarm; wherein, the confirmation information is the information of the user operating the pop-up window displayed on the touch screen.

[0087] The principle and beneficial effects of the above technical solution are:

[0088] The application can determine the specific skewness corresponding to the current working state of the compound machine by judging the error amount on the current monitoring result, thereby determining the specific risk level. Finally, according to the preset level requirement met by the risk level of the working state of the compound machine, the specific alarm instruction is displayed through a pop-up window, and the alarm is realized through the alarm instruction. The confirmation information is the information for closing the alarm. If the confirmation information is received within the preset time period, it indicates that the alarm information has been received, and the alarm can be directly closed. If the confirmation information is not received, the alarm is performed again, thereby reducing the risk of stopping the compound machine.

[0089] In one embodiment, the system further comprises a first support 10 and a second support 11, which are movably mounted on the compound machine and are fixedly connected with the first position sensor 3 and the second position sensor 4, respectively.

[0090] The principle and beneficial effects of the above technical solution are:

[0091] The first support 10 can position and fix the position of the first detection sensor, and can realize smooth movement and stable fixation under automatic control in the working process, as well as smooth movement under electric control and manual focus adjustment in the preparation adjustment process. The function of the second support 11 is the same as that of the first support 10, which will not be described in detail here.

[0092] Preferably, the second support 11 is connected with the control module to drive the second position sensor 4 to move. The control module further comprises an adjustment module, which is used to adjust the position of the second position sensor 4 according to the deviation distance when the transverse position collected by the first position sensor 3 does not coincide with the reference position and after the deviation correction device completes the deviation correction action, so as to avoid false reporting of the second position sensor 4.

[0093] The principle and beneficial effects of the above technical solution are:

[0094] The adjustment module adjusts the zero position of the sensor according to the error between the first base material and the second base material after the transverse position collected by the first position sensor 3 does not coincide with the reference position, the second position sensor 4 has completed the corresponding transverse movement, and the deviation correction device has completed the deviation correction action, so as to eliminate the initial error.

[0095] In one embodiment, the deviation correction device is a first deviation correction mechanism 5 located downstream of the unwinding device in the compound machine. It can realize deviation correction on the original mechanism of the compound machine without changing the structure of the compound machine.

[0096] The principle and beneficial effects of the above technical solution are:

[0097] As shown in FIG. 1, the compound machine comprises a first position sensor 3 and a second position sensor 4. Figure 3, the first deviation distance of the first deviation mechanism 5 is: when the position of the first substrate 1 changes, the deviation distance is W0=W1 at this time; when the positions of the first substrate 1 and the second substrate 2 change and the directions are opposite, the deviation distance is W0=W1+W2 at this time; when the positions of the first substrate 1 and the second substrate 2 change and the directions are the same, the deviation distance is W0=W1-W2 at this time.

[0098] The first deviation mechanism 5 includes a deviation controller and a deviation driver. The first position sensor 3 first forms a reference position by automatic positioning according to the theoretical center of the substrate during operation, and no longer moves during operation; when the transverse position of the first substrate 1 and / or the second substrate 2 changes, the deviation distance is calculated, and the control module controls the deviation controller and the deviation driver to adjust the transverse position of the second substrate 2 according to the deviation distance, so that the second substrate 2 is aligned with the first substrate 1, and deviation is realized.

[0099] The control module further includes a cycle selection sub-module, which is used to determine the cycle of signal acquisition according to the error amount. The acquisition cycle is reasonably set to effectively reduce the delay lag amount.

[0100] A coating substrate composite deviation control method, comprising the following steps,

[0101] Real-time monitoring is performed when the first substrate 1 and the second substrate 2 move with the roller body to determine the real-time transverse position data before compounding; wherein,

[0102] The real-time transverse data includes real-time transverse data of the first substrate 1 and real-time transverse data of the second substrate 2;

[0103] The error between the real-time transverse position data and the preset reference position is calculated to determine the deviation distance;

[0104] According to the deviation distance, the transverse position of the second substrate 2 is adjusted so that the reference position of the second substrate 2 and the first substrate 1 coincide.

[0105] The principle of the above technical solution is:

[0106] As shown in the accompanying Figure 5 , the accompanying Figure 2 , the accompanying Figure 3 and the accompanying Figure 4As shown, before the substrate is compounded, the error amount of the transverse position of the first substrate 1 and the second substrate 2 detected by the sensing module and the reference position determines the correction distance, and the position of the second substrate 2 is corrected by the correction device to ensure that the reference positions of the second substrate 2 and the first substrate 1 are real-time coincident. Since the first substrate 1 at the outlet of the oven is in an unstable state, when the transverse position of the first substrate 1 at the outlet of the oven changes, it is not adjusted, but the transverse position of the second substrate 2 is adjusted by the correction device, so that the second substrate 2 has a following relationship, so as to realize the coincidence of the reference positions of the two substrates, avoid the tension effect of the correction process on the first substrate 1, and reduce the generation of wrinkles. When the position of the first substrate 1 or the second substrate 2 deviates, only the position of the second substrate 2 is adjusted, which can prevent the product quality from being reduced due to the changeable characteristics of the first substrate 1 at the outlet of the oven. The present application not only corrects the first substrate 1 at the oven of the two-in-one compound machine device, but also can be used for the correction of long-path substrates, and removes the process correction, and a terminal correction solves all the centering problems. In the control principle, A+B=0 is followed, wherein A is the instantaneous position error value of the first substrate, and B is the cumulative movement value of the second substrate.

[0107] The beneficial effects of the above technical solutions are:

[0108] Because in the prior art, the substrate is in a high temperature and easy-to-stretch state, which is easy to deform and form wrinkles, the correction distance is obtained by the sensing device after using the device of the present application, and the influence of high temperature is not considered during correction, and then the reference positions of the two substrates are coincident, which avoids the tension effect, that is, the easy-to-stretch state can be handled, and finally, a set of system can control the correction treatment in the substrate compounding step.

[0109] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
