Description

Technical Field

[0001] The present invention relates to the technical field of control systems, and in particular to a real-time deviation correction method and system applied to a carbon paper hydrophobic treatment line. Background Art

[0002] Carbon paper, also known as carbon fiber paper, is a special material for fuel cell experiments. It is often used as a gas diffusion layer and is widely used in fuel cell proton exchange membranes.

[0003] Newly purchased carbon paper is typically hydrophilic and has poor strength. To create pores for gas flow and increase its strength, the carbon paper needs to be pre-treated to be hydrophobic. This is typically done by impregnating the carbon paper with a hydrophobic agent solution. After impregnation, the carbon paper is dried and sintered to allow the hydrophobic agent to form a network within the paper, resulting in excellent drainage properties.

[0004] Carbon paper hydrophobic treatment lines often experience deviation during the carbon paper feeding process. Without real-time correction, uneven tension distribution can cause the carbon paper to break. Therefore, it is necessary to develop a real-time correction method for carbon paper hydrophobic treatment lines to prevent breakage caused by deviation during the treatment process. Summary of the Invention

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0047] like Figure 1 As shown, a real-time deviation correction method applied to a carbon paper hydrophobic treatment line in one embodiment of the present invention is applied in a real-time deviation correction system, which includes the following steps:

[0048] S1, obtaining speed parameters and material parameters of carbon paper to be hydrophobized in a carbon paper hydrophobic treatment line.

[0049] S2, obtaining a first deviation parameter of the carbon paper to be hydrophobically treated by a first deviation obtaining device.

[0050] S3, obtaining a second deviation parameter of the carbon paper to be hydrophobically treated by a second deviation obtaining device.

[0051] Specifically, when the carbon paper is running normally or not deviating, both the first deviation acquisition device and the second deviation acquisition device have an initial distance value from the edge of the carbon paper. The first deviation acquisition device converts the corresponding initial distance value into a first initial distance signal value, and the second deviation acquisition device converts the corresponding initial distance value into a second initial distance signal value.

[0052] When the carbon paper deviates, the real-time distance values ​​between the edge of the carbon paper and both the first deviation acquisition device and the second deviation acquisition device change. The first deviation acquisition device acquires a first real-time distance signal value, compares the first real-time distance signal value with the first initial distance signal value, and acquires the first deviation parameter. The second deviation acquisition device acquires a second real-time distance signal value, compares the second real-time distance signal value with the two initial distance signal values, and acquires the second deviation parameter.

[0053] The first deviation obtaining device obtains a first displacement of the edge of the carbon paper according to the first deviation parameter, and the second deviation obtaining device obtains a second displacement of the edge of the carbon paper according to the second deviation parameter.

[0054] Here, preferably, the first deviation acquisition device and the second deviation acquisition device are both configured to be installed on one side of the carbon paper and to acquire corresponding deviation parameters based on the deviation value of the carbon paper. That is, when the carbon paper deviates, the first deviation acquisition device acquires a first deviation parameter corresponding to a first displacement of the carbon paper edge, and the second deviation acquisition device acquires a second deviation parameter corresponding to a second displacement of the carbon paper edge.

[0055] S4, correcting the first deviation parameter and the second deviation parameter according to the speed parameter and the material parameter.

[0056] Specifically, in step S4, if Figure 2 As shown, the specific method for correcting the first deviation parameter and the second deviation parameter according to the speed parameter and the material parameter includes the following steps:

[0057] S41: Correct the first deviation parameter according to the speed parameter and the material parameter.

[0058] Here, the speed parameter refers to the moving speed of the carbon paper tape. Material parameters include but are not limited to the grammage of the material.

[0059] In some cases, due to differences in speed parameters and material parameters, even if the edge of the carbon paper touches the first deviation acquisition device and causes the first deviation acquisition device to sense the first displacement, since the edge of the carbon paper may be bent and deformed, the first displacement is not the actual first displacement of the edge of the carbon paper, and the first displacement obtained according to the first deviation parameter has an error.

[0060] To this end, it is necessary to correct the first deviation parameter based on the speed parameter and material parameter of the carbon paper to reduce errors and improve the accuracy of the first deviation parameter. The specific method for correcting the first deviation parameter includes presetting correction coefficients corresponding to different material parameters at different speed parameters, obtaining the real-time speed parameter and material parameter of the carbon paper, and correcting the first deviation parameter based on the correction coefficients corresponding to the real-time speed parameter and material parameter.

[0061] Since the correction coefficient can be obtained through a limited number of experiments according to the ratio between the actual displacement of the carbon paper edge and the first displacement measured by the first deviation obtaining device during the experiment, it will not be described in detail here.

[0062] S42: Acquire a compensation factor of the second deviation acquiring device according to the distance value between the first deviation acquiring device and the second deviation acquiring device.

[0063] S43: Correct the second deviation parameter according to the compensation factor, the speed parameter, and the material parameter.

[0064] In actual circumstances, when the carbon paper deviates, under the same speed parameters and material parameters, the change in the distance value between the first deviation acquisition device and the second deviation acquisition device will cause even if the second deviation parameter is corrected using the correction coefficient, the second displacement obtained based on the corrected second deviation parameter will still have an error different from the actual second displacement. For example, when the first deviation parameter remains unchanged and the distance value between the first deviation acquisition device and the second deviation acquisition device changes, the second deviation parameter and the second displacement will change accordingly. The change in the second displacement will cause the reaction force of the second deviation acquisition device on the edge of the carbon paper to change, so that the degree of bending deformation of the carbon paper edge corresponding to the second deviation acquisition device is different from the bending deformation of the carbon paper edge corresponding to the first deviation acquisition device. Ultimately, the second displacement obtained by the corrected second deviation parameter will still have an error different from the actual second displacement.

[0065] To improve the accuracy of obtaining the second deviation parameter and the second displacement, the second deviation parameter needs to be further corrected. This can be achieved by obtaining a compensation factor for the second deviation obtaining device based on the distance between the first and second deviation obtaining devices, and correcting the second deviation parameter based on the compensation factor, the speed parameter, and the material parameter.

[0066] The specific method for obtaining the compensation factor of the second deviation acquisition device based on the distance value between the first deviation acquisition device and the second deviation acquisition device includes: pre-obtaining the compensation factors corresponding to different first deviation parameters under different distance values, and obtaining the corresponding compensation factor based on the real-time distance value between the first deviation acquisition device and the second deviation acquisition device and the real-time first deviation parameter.

[0067] The first deviation acquiring device is closer to the unwinding end of the carbon paper roll than the second deviation acquiring device, and the first deviation acquiring device and the second deviation acquiring device are located on the same side of the carbon paper.

[0068] By correcting the first deviation parameter and correcting the second deviation parameter based on the corrected first deviation parameter, the accuracy of obtaining the first deviation parameter and the second deviation parameter can be improved, so as to better perform real-time deviation correction operations on the carbon paper to be hydrophobically treated.

[0069] S5: Obtain a real-time deviation angle according to the corrected first deviation parameter and the corrected second deviation parameter.

[0070] S6, performing a real-time deviation correction operation on the carbon paper to be hydrophobically treated according to the real-time deviation angle.

[0071] The real-time deviation correction method applied to a carbon paper hydrophobic treatment line first obtains the speed parameter and material parameter of the carbon paper to be hydrophobicized in the carbon paper hydrophobic treatment line, the first deviation parameter, and the second deviation parameter, and then corrects the first deviation parameter and the second deviation parameter based on the speed parameter and the material parameter. This method can take into account the influence of the carbon paper speed parameter and the material parameter on the parameter acquisition accuracy of the first deviation acquisition device and the second deviation acquisition device, and can reduce the acquisition error of the first deviation parameter and the second deviation parameter.

[0072] On the basis of reducing the acquisition errors of the first deviation parameter and the second deviation parameter, after obtaining the real-time deviation angle according to the corrected first deviation parameter and the corrected second deviation parameter, and performing real-time deviation correction operations on the carbon paper to be hydrophobicized according to the real-time deviation angle, the real-time deviation correction accuracy of the carbon paper hydrophobic treatment line can be improved, and the problem of carbon paper breaking due to deviation during the hydrophobic treatment process can be better avoided.

[0073] In one embodiment, in step S5, a specific method for obtaining a real-time deviation angle according to the corrected first deviation parameter and the corrected second deviation parameter includes the following steps:

[0074] S50: Obtain a horizontal deviation value A according to the corrected first deviation parameter and the corrected second deviation parameter.

[0075] S51 , obtaining the real-time deviation angle θ=arctanA / B according to the horizontal deviation value A and the distance value B.

[0076] In step S6, Figure 3 As shown, the specific method for performing a real-time deviation correction operation on the carbon paper to be treated with hydrophobicity according to the real-time deviation angle includes the following steps:

[0077] S60, obtaining the tension value and speed value of the carbon paper in the carbon paper hydrophobic treatment line, and determining whether the tension value is within a preset tension value range and whether the speed value is within a preset speed value range.

[0078] S61, if the tension value is not within the preset tension value range, adjust the tension value until the tension value is within the preset tension value range; if the speed value is not within the preset speed value range, adjust the speed value until the speed value is within the preset speed value range.

[0079] S62, determining whether the real-time deviation angle is less than a preset deviation threshold; if not, adjusting the guide rollers at the unloading end and / or the receiving end of the carbon paper roll according to the real-time deviation angle until the real-time deviation angle is less than the preset deviation threshold.

[0080] By first adjusting the speed value and the tension value to ensure that the speed value is within the preset speed value range and the tension value is within the preset tension value range, and then adjusting the guide roller at the unloading end and / or the receiving end of the carbon paper roll according to the real-time deviation angle until the real-time deviation angle is less than the preset deviation threshold, the carbon paper hydrophobic treatment line can be corrected in real time to ensure the stability of the carbon paper belt running and avoid frequent deviation of the carbon paper.

[0081] In one embodiment, the present invention provides a real-time deviation correction system applied to a carbon paper hydrophobic treatment line, which includes a first parameter acquisition module, a second parameter acquisition module, a first deviation acquisition device, a second deviation acquisition device, a correction module, a real-time deviation angle acquisition module and a deviation correction module.

[0082] The first parameter acquisition module is used to acquire the speed parameter of the carbon paper to be hydrophobized in the carbon paper hydrophobic treatment line; the second parameter acquisition module is used to acquire the material parameter of the carbon paper to be hydrophobized in the carbon paper hydrophobic treatment line.

[0083] The first deviation obtaining device is used to obtain a first deviation parameter of the carbon paper to be hydrophobically treated; the second deviation obtaining device is used to obtain a second deviation parameter of the carbon paper to be hydrophobically treated.

[0084] The correction module corrects the first deviation parameter and the second deviation parameter according to the speed parameter and the material parameter; the real-time deviation angle acquisition module is used to obtain the real-time deviation angle according to the corrected first deviation parameter and the corrected second deviation parameter.

[0085] The deviation correction module is used to perform a real-time deviation correction operation on the carbon paper to be hydrophobically treated according to the real-time deviation angle.

[0086] Specifically, the correction module includes a first correction unit, a compensation unit, and a second correction unit. The first deviation acquisition device is closer to the unwinding end of the carbon paper roll than the second deviation acquisition device, and the first deviation acquisition device and the second deviation acquisition device are located on the same side of the carbon paper. The first deviation acquisition device and the second deviation acquisition device are both configured to sense the force applied by the edge of the carbon paper and convert the force into a corresponding electrical signal value. For example, the first deviation acquisition device and the second deviation acquisition device convert the force applied by the edge of the carbon paper into a corresponding electrical signal (including but not limited to a voltage signal or a current signal), and then calculate the first deviation parameter and the second deviation parameter based on the electrical signal.

[0087] The first deviation acquisition device, unlike the second deviation acquisition device, includes a sliding resistor and a reset unit. The reset unit is mounted on the sliding resistor and is used to provide a force to drive the slider of the sliding resistor back to its initial position when the slider deviates from the initial position. For example, the reset unit can be a spring component that applies an elastic tension or spring force to the slider to force the slider back to its initial position when the edge of the carbon paper applies a force to the slider and causes the slider to slide along the resistance wire of the sliding resistor and deviate from the initial position. The specific structure of the reset unit, such as the elastic coefficient of the spring component, can be adjusted and set according to actual needs and will not be detailed here.

[0088] The first deviation obtaining device obtains the corresponding first deviation parameter and second deviation parameter according to the resistance change value of the corresponding sliding rheostat compared to the second deviation obtaining device.

[0089] The first correction unit is used to correct the first deviation parameter according to the speed parameter and the material parameter.

[0090] The compensation unit is configured to obtain a compensation factor of the second deviation obtaining device according to a distance value between the first deviation obtaining device and the second deviation obtaining device.

[0091] The second correction unit is used to correct the second deviation parameter according to the compensation factor, the speed parameter and the material parameter.

[0092] In actual situations, when the carbon paper deviates, under the same speed parameters and material parameters, the change in the distance value between the first deviation acquisition device and the second deviation acquisition device will cause the second displacement value obtained based on the corrected second deviation parameter to still have an error with the actual second displacement value even if the second deviation parameter is corrected using the correction coefficient.

[0093] To improve the accuracy of obtaining the second deviation parameter and the second displacement, the second deviation parameter needs to be further corrected. This can be achieved by obtaining a compensation factor for the second deviation obtaining device based on the distance between the first and second deviation obtaining devices, and correcting the second deviation parameter based on the compensation factor, the speed parameter, and the material parameter.

[0094] By correcting the first deviation parameter and correcting the second deviation parameter based on the corrected first deviation parameter, the accuracy of obtaining the first deviation parameter and the second deviation parameter can be improved, so as to better perform real-time deviation correction operations on the carbon paper to be hydrophobically treated.

[0095] As a preferred technical solution, the elastic coefficient of the spring in the spring component is 0.002N / mm, the carbon paper running speed is 1M / min to 3M / min, and the carbon paper weight is 30g / m 2 -90g / m 2 When, according to the formula The first deviation parameter is corrected; wherein D1 represents the first deviation parameter of the carbon paper obtained by the first deviation obtaining device, grm represents the grammage of the carbon paper, and D1' represents the corrected first deviation parameter.

[0096] According to the formula The second deviation parameter is corrected; wherein D2 represents the second deviation parameter of the carbon paper obtained by the second deviation obtaining device, ε represents the compensation factor, and D2' represents the corrected second deviation parameter.

[0097] Furthermore, the specific method by which the compensation unit obtains the compensation factor of the second deviation acquisition device based on the distance value between the first deviation acquisition device and the second deviation acquisition device is: obtaining the compensation factor of the second deviation acquisition device based on the distance value between the first deviation acquisition device and the second deviation acquisition device and the corresponding first deviation parameter.

[0098] The specific method for obtaining the compensation factor of the second deviation acquisition device based on the distance value between the first deviation acquisition device and the second deviation acquisition device and the corresponding first deviation parameter includes: pre-obtaining the compensation factors corresponding to different first deviation parameters under different distance values, and obtaining the corresponding compensation factor based on the real-time distance value between the first deviation acquisition device and the second deviation acquisition device and the real-time first deviation parameter.

[0099] Specifically, a compensation factor fitting curve can be obtained by performing curve fitting on the compensation factors corresponding to different first deviation parameters under a certain distance value. The compensation factor fitting curve is a curve function of the first deviation parameter to the compensation factor. After obtaining the real-time distance value and the real-time first deviation parameter, the compensation factor fitting curve corresponding to the real-time first deviation parameter input value and the real-time distance value is used to obtain the corresponding compensation factor.

[0100] The real-time deviation angle acquisition module includes a horizontal deviation acquisition unit and a deviation angle acquisition unit.

[0101] The horizontal deviation acquisition unit is used to obtain a horizontal deviation value according to the corrected first deviation parameter and the corrected second deviation parameter; the deviation angle acquisition unit is used to obtain the real-time deviation angle according to the horizontal deviation value and the distance value.

[0102] On the basis of reducing the acquisition errors of the first deviation parameter and the second deviation parameter, after obtaining the real-time deviation angle according to the corrected first deviation parameter and the corrected second deviation parameter, the carbon paper to be hydrophobic treated is subjected to real-time correction operation according to the real-time deviation angle. The real-time correction system applied to the carbon paper hydrophobic treatment line can improve the real-time correction accuracy of the carbon paper hydrophobic treatment line, and better avoid the problem of carbon paper breaking due to deviation during the hydrophobic treatment process.

[0103] In one embodiment, the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the real-time deviation correction method applied to a carbon paper hydrophobic treatment line.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
