[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Hereinafter, a method for cutting a catalyst coating membrane according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0036] like Figure 1-Figure 11 As shown, the method for cutting the catalyst coating membrane according to an embodiment of the present invention comprises:

[0037] S10: Presetting the cutting position. That is, the cutting position may be preset first, so that the cutting module 102 can cut the sheet material 10 at the cutting position.

[0038] S20: Drive the sheet material 10 to move a preset distance along the first direction toward the cutting position. That is, after the cutting position is set, the driving module 101 can drive the sheet material 10 from the initial position along the first direction (i.e. Figure 2 The sheet 10 moves a preset distance in the right direction (in the right direction) so that the sheet 10 can enter the cutting position to be opposite to the cutting module 102.

[0039] It should be noted that when the sheet material 10 is processed, the driving module 101 can drive at least a portion of the sheet material 10 to move to the cutting position, and then the cutting module 102 cuts at least a portion of the sheet material 10 that enters the cutting position, and the cut portion of the sheet material 10 is discarded, and the position is determined as the initial position. For example, when the running trajectory of the cutting module 102 is as follows Figure 4 As shown in the cutting trajectory 1, if the sheet 10 only occupies a partial area of ​​the cutting position, the cutting module can cut off the portion of the sheet 10 located at the cutting position to form waste; if the sheet 10 completely occupies the cutting position, the portion of the sheet 10 corresponding to the cutting position cannot be cut off, and the portion is directly discarded.

[0040] S30: Cut the portion of the sheet 10 located at the cutting position to form a catalyst coating membrane 30, and transport the cut catalyst coating membrane 30 away. That is to say, when the sheet 10 enters the cutting position, the drive module 101 stops running, the sheet 10 remains stationary, and the cutting module 102 can cut the sheet 10 to form the catalyst coating membrane 30. It should be noted that the sheet 10 is placed on the protective film 20, and the protective film 20 is used to fix the sheet 10. The drive module 101 can drive the sheet 10 to move synchronously by winding the protective film 20. The cutting module 102 can cut the sheet 10 to form the catalyst coating membrane 30 without damaging the protective film 20. The processed catalyst coating membrane 30 is still located on the protective film 20. At this time, the catalyst coating membrane 30 can be transported away by the transport module 103.

[0041] S40: driving the sheet material 10 to move a preset distance along the first direction toward the cutting position and cutting again; wherein the preset distance is equal to the extension dimension of the catalyst coating film 30 along the first direction. That is, after the transfer of the catalyst coating film 30 is completed, the driving module 101 can be used to drive the sheet material 10 to move a preset distance along the first direction again, so that the next part of the sheet material 10 can enter the cutting position, and the cutting module 102 can cut the sheet material 10 again to form another catalyst coating film 30, and so on.

[0042] The preset distance is equal to the extension size of the catalyst coating membrane 30 along the first direction. Figure 2 As shown, the area where a plurality of catalyst coating membranes 30 are processed on the sheet material 10 is continuous, which can reduce the waste rate of the sheet material 10 compared with the existing intermittent cross-cutting method.

[0043] The catalyst coating membrane cutting method according to the embodiment of the present invention can reduce the waste rate of the sheet material 10 , and the sheet material 10 is not prone to wrinkles during the cutting process, thereby ensuring the processing yield of the catalyst coating membrane 30 and helping to reduce the processing cost of the catalyst coating membrane 30 .

[0044] In some embodiments of the present invention, Figure 3-Figure 4 As shown, cutting the portion of the sheet material 10 at the cutting position to form the catalyst coating membrane 30 includes:

[0045] S50: preset cutting track 1. That is, when the sheet 10 enters the cutting position, the cutting track 1 of the cutting module 102 can be generated according to the size of the catalyst coating membrane 30 and the size of the sheet 10. Of course, the same cutting track 1 can be directly used when cutting the next catalyst coating membrane 30, which will not be repeated here.

[0046] S60: Cut the sheet material 10 along the cutting track 1. That is, after the cutting track 1 is formed, the cutting module 102 can be driven to move along the cutting track 1 to cut the catalyst coating membrane 30 from the sheet material 10. It should be noted that the cutting module 102 can be set as a flat knife. In this way, the cutting quality of the catalyst coating membrane 30 can be guaranteed.

[0047] In some embodiments of the present invention, Figure 4-Figure 5 As shown, the preset cutting track 1 includes:

[0048] S51: Move the first preset distance from the first side edge 10a of the sheet 10 in a direction opposite to the first direction to form a first cutting track 11. That is, the cutting module 102 can be driven to move the first preset distance from the first side edge 10a of the sheet 10 in a direction opposite to the first direction ( Figure 4 The cutting module 102 moves in the left direction in the figure to form a first cutting track 11 after the cutting module 102 moves a first preset distance.

[0049] S52: Move a second preset distance in a direction perpendicular to the first direction to form a second cutting track 12. That is, after the cutting module 102 forms the first cutting track 11, the cutting module 102 can be driven to move in a direction perpendicular to the first direction ( Figure 4 The cutting track 12 is formed after the second preset distance is moved.

[0050] S53: Move the first preset distance along the first direction from the second side 10b of the sheet 10 to form a third cutting track 13. That is, after the cutting module 102 forms the second cutting track 12, the cutting module 102 is located at a position of the sheet 10 close to the second side 10b. At this time, the sheet 10 can be driven to move along the first direction ( Figure 4 The first cutting track 13 is formed after the first preset distance is moved.

[0051] It is understandable that the cutting module 102 only needs to move along the first cutting track 11, the second cutting track 12 and the third cutting track 13 to complete the cutting of the catalyst coating membrane 30, which is beneficial to reduce the movement stroke of the cutting module 102 and reduce the difficulty of cutting.

[0052] It should be noted that the first preset distance and the second preset distance are set according to the size of the catalyst coating membrane 30, the second preset distance is equal to the extension length of the catalyst coating membrane 30 along the direction perpendicular to the first direction, and the first preset distance is greater than or equal to the extension size of the catalyst coating membrane 30 along the first direction.

[0053] Of course, after the cutting module 102 forms the third cutting track 13, the cutting module 102 can be driven to cut along another direction perpendicular to the first direction at the end of the third cutting track 13 ( Figure 4 The cutting module 102 moves in the upper direction of the sheet material 10, so that the cutting module 102 can form a fourth cutting track after moving the second preset distance, thereby constructing a ring-shaped cutting track 1. In this way, the catalyst coating film 30 and the rest of the sheet material 10 can be cut off, which is conducive to improving the processing yield of the catalyst coating film 30.

[0054] In some embodiments of the present invention, Figure 6 As shown, the preset cutting track 1 also includes:

[0055] S54: Obtain the initial point and the end point of the cutting track 1. It should be noted that the first cutting track 11 and the third cutting track 13 need to maintain a sufficient distance from the side edges of the corresponding sides of the sheet 10 to ensure that there is sufficient adhesion between the sheet 10 and the protective film 20, thereby avoiding wrinkles in the sheet 10 during the cutting process.

[0056] That is to say, when the sheet 10 enters the cutting position, the starting point and the ending point of the cutting track 1 can be determined according to the width of the catalyst coating membrane 30, combined with the distance between the first cutting track 11 and the first side 10a of the sheet 10, and the distance between the third cutting track 13 and the second side 10b of the sheet 10.

[0057] S55: Determine the first cutting track 11, the second cutting track 12 and the third cutting track 13 according to the initial point and the end point. That is, after the initial point and the end point of the cutting track 1 are determined, the first cutting track 11, the second cutting track 12 and the third cutting track 13 can be determined according to the positions of the initial point and the end point. This is beneficial to improving the cutting quality of the catalyst coating membrane 30.

[0058] In some embodiments of the present invention, Figure 7 As shown, S54: obtaining the initial point and the end point of the cutting track 1 includes:

[0059] S541: Select an initial point at a position having a first spacing distance from the first side edge 10a of the sheet 10. That is, select an initial point at a position having a first spacing distance from the first side edge 10a of the sheet 10 so that a sufficient distance can be maintained between the first cutting track 11 and the first side edge 10a of the sheet 10. Thus, the influence of the cutting module 102 on the stability of the sheet 10 when running along the first cutting track 11 can be reduced, which is conducive to improving the cutting quality of the catalyst coating membrane 30.

[0060] S542: Select an end point at a position having a second spacing distance from the second side edge 10b of the sheet 10. That is, select an end point at a position having a second spacing distance from the second side edge 10b of the sheet 10 so that there is a sufficient spacing between the third cutting track 13 and the first side edge 10a of the sheet 10. Thus, the influence of the cutting module 102 on the stability of the sheet 10 when running along the third cutting track 13 can be reduced, which is conducive to improving the cutting quality of the catalyst coating membrane 30.

[0061] It should be noted that the first spacing distance and the second spacing distance are selected based on the experience and experimental data of the designer, and the present invention does not impose any limitation on this.

[0062] In some embodiments of the present invention, the first spacing distance and the second spacing distance may be set to be not less than 10 mm. Through the above setting, the probability of wrinkles in the sheet material 10 during cutting can be reduced, which is conducive to improving the processing quality of the catalyst coating membrane 30.

[0063] In some embodiments of the present invention, Figure 8 As shown, S54: obtaining the initial point and the end point of the cutting track 1 includes:

[0064] S543: Select an initial point and an end point on the side of the cutting position facing the first direction. Figure 4 The first cutting track 11 and the third cutting track 13 are selected as the starting point and the ending point, so that the first cutting track 11 and the third cutting track 13 can extend to the side of the cutting position facing the first direction, and the first preset distance is greater than the extension dimension of the catalyst coating film 30 along the first direction, so as to ensure that the first cutting track 11 and the third cutting track 13 can completely cut off the connection between the catalyst coating film 30 and the rest of the sheet material 10. In this way, the processing yield of the catalyst coating film 30 can be improved.

[0065] In some embodiments of the present invention, Fig. 9 As shown, S55: determining the first cutting track 11, the second cutting track 12 and the third cutting track 13 according to the initial point and the end point includes:

[0066] S551: Determine that the extension dimension of the second cutting track 12 is greater than the extension dimension of the first cutting track 11 and the extension dimension of the third cutting track 13. It should be noted that the catalyst coating membrane 30 is usually a rectangular structure with inconsistent length and width, such as 275mm×145mm. In other words, the extension dimension of the second cutting track 12 can be set to be greater than the extension dimension of the first cutting track 11 and the extension dimension of the third cutting track 13, that is, the second cutting track 12 is set to correspond to the length direction of the catalyst coating membrane 30, and the first cutting track 11 and the third cutting track 13 are set to correspond to the width direction of the catalyst coating membrane 30. In this way, the sum of the extension dimensions of the first cutting track 11, the second cutting track 12 and the third cutting track 13 can be reduced. As a result, the movement stroke of the cutting module 102 can be reduced, which is beneficial to energy saving.

[0067] In some embodiments of the present invention, Fig.10 As shown, transporting the cut catalyst coating membrane 30 includes:

[0068] S71: Grab the catalyst coating membrane 30 from the cutting position. That is, when the catalyst coating membrane 30 is cut, the catalyst coating membrane 30 is still on the protective membrane 20. At this time, the transfer module 103 can be driven to move to the cutting position so that the transfer module 103 can grab the catalyst coating membrane 30. It should be noted that the transfer module 103 can be set as a manipulator.

[0069] S72: Transfer the captured catalyst coating membrane 30 to the storage position. That is, after the transfer module 103 grabs the catalyst coating membrane 30, the transfer module 103 can be driven to move to the storage position, and then the catalyst coating membrane 30 is transferred to the storage position. Through the above arrangement, the catalyst coating membrane 30 can be conveniently transferred.

[0070] The present invention also provides a catalyst coating membrane cutting device 100 .

[0071] like Fig.11 As shown, according to the catalyst coating membrane cutting device 100 of the embodiment of the present invention, the cutting device 100 is applicable to the cutting method of any of the above embodiments, and the cutting device 100 includes: a driving module 101, a cutting module 102 and a transfer module 103, the driving module 101 drives the sheet material 10 to move to the cutting position along the first direction; the cutting module 102 is used to cut the portion of the sheet material 10 located at the cutting position to form the catalyst coating membrane 30; the transfer module 103 is used to transfer the cut catalyst coating membrane 30 away. According to the catalyst coating membrane cutting device 100 of the embodiment of the present invention, the practicability is high.

[0072] It should be noted that the driving module 101 can be configured as a winding roller, and the protective film 20 is suitable for being wound on the winding roller, and the winding roller can drive the sheet material 10 to move by winding the protective film 20 .
