Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and particularly to a cutting adjustment method and system for a laser cutting machine. Background Art

[0002] At present, a laser cutting machine is a device that uses laser technology to cut non-metals or metals. The laser cutting machine has the advantages of fast cutting speed, high precision, smooth cutting surface without burrs, and small heat-affected zone.

[0003] In the prior art, during the process of laser cutting the blank corresponding to non-metals or metals, the blank is usually placed in the cutting area of the laser cutting machine, and different blank specifications and the shapes to be cut are input into relevant equipment to form the cutting path of the laser cutting machine, and the laser cutting head of the laser cutting machine is controlled to move and cut along the cutting path with a fixed laser power.

[0004] In view of the above related technologies, during the actual cutting of the blank, different regions of the blank have different thicknesses. If the cutting reaches the region with a relatively thin thickness on the blank, using a fixed laser power will cause the region with a relatively thin thickness on the blank to melt too quickly, affecting the cutting effect. If the cutting reaches the region with a relatively thick thickness on the blank, using a fixed laser power will cause the region with a relatively thick thickness on the blank to be not easily melted, affecting the cutting effect, thereby reducing the cutting quality of laser cutting.

[0094] In summary, the present application includes at least one of the following beneficial technical effects:

[0095] 1. Determine the thickness deviation information on the cutting path through the blank specification, the product shape, and the real-time blank thickness, and determine the laser control information through the thickness deviation information and output it to the laser cutting device, so that when there are different thicknesses in a single blank, the laser power of the laser cutting machine can be adjusted in real time, thereby reducing the influence of the fixed laser power on the cutting effect of the blank, such as being not easily melted or melted too fast, and improving the cutting quality of laser cutting;

[0101] The following combines the attached Figures 1 to 3 and embodiments to further describe the present invention in detail.

[0102] A method and system for cutting adjustment of a laser cutting machine, by adjusting the power of the laser generated by the laser cutting machine in real time according to the thickness of the blank on the path corresponding to the laser cutting of a single blank, and further analyzing the concave and convex radians on the blank, the concave and convex directions of the radians, the cleaning of the dust on the blank by the roller, and the cleaning path of the roller when there are radians, so as to reduce the influence on the laser cutting effect in the case of different thicknesses and the presence of dust on a single blank, and further improve the cutting quality of laser cutting.

[0103] Refer to Figure 1 , an embodiment of the present application discloses a method for cutting adjustment of a laser cutting machine, including the following steps:

[0104] Step S100: Obtain the blank specifications to be cut, the product shape of the product obtained after cutting, and the real-time blank thickness.

[0105] The blank specification refers to the parameter specifications such as the dimensions, shape, and color of the blank to be cut. The operator manually inputs the parameters of the blank to be cut as the blank specification. The product shape refers to the shape of the product obtained after cutting the blank. The operator manually inputs the required dimensional parameters of the product and combines them to form the product shape. The real-time blank thickness refers to the thickness of the blank detected in real time. The parameter obtained by detecting the blank with a thickness detection device preset on the laser detection device is used as the real-time blank thickness.

[0106] In this embodiment, the thickness detection device detects the blank through two vertical infrared detection devices. The distance corresponding to the blank located between the two infrared rays is calculated by the two infrared detection devices to obtain the parameters of the blank. And if there is an arc on the upper surface or the lower surface of the blank, there is a deviation in the distance detected by the corresponding infrared rays, so that the operator can know the position of the surface where the blank arc appears.

[0107] Step S101: Retrieve the reference blank thickness based on the blank specification.

[0108] The reference blank thickness refers to the reference thickness corresponding to the blank to be cut. By retrieving the reference blank thickness from the blank specification, it is convenient for subsequent analysis.

[0109] Step S102: Match the reference power from the preset laser database based on the reference blank thickness.

[0110] The reference power refers to the thickness corresponding to the laser cutting equipment for cutting the reference blank thickness. The reference power is retrieved by matching and searching from the laser database based on the reference blank thickness. Different blank thicknesses and the corresponding powers of the laser generated by the laser cutting equipment are pre-stored manually in the laser database, which will not be elaborated here.

[0111] Step S103: Determine the cutting path according to the product shape.

[0112] The cutting path refers to the path corresponding to the laser cutting equipment cutting out the product shape on the blank. The parameters corresponding to the product shape are input into the laser cutting equipment and the corresponding path is formed as the cutting path.

[0113] Step S104: Determine the real-time cutting thickness according to the real-time blank thickness and the cutting path.

[0114] The real-time cutting thickness refers to the thickness of the blank detected in real time on the cutting path. The thickness corresponding to the cutting path is retrieved from the real-time blank thickness as the real-time cutting thickness.

[0115] Step S105: Determine the thickness deviation information according to the comparison between the reference blank thickness and the real-time cutting thickness.

[0116] The thickness deviation information refers to the parameter information of the thickness deviation existing on the blank. By comparing the reference blank thickness with the real-time cutting thickness, the parameter information of the position corresponding to the inconsistency between the reference blank thickness and the real-time cutting thickness and the deviation value is combined to form the thickness deviation information.

[0117] Step S106: Based on the thickness deviation information, match the adjustment power from the laser database and adjust the reference power to determine the changed power.

[0118] The adjustment power refers to the power that needs to be adjusted by the laser cutting equipment. After retrieving and matching from the laser database through the thickness deviation information, the adjustment power is retrieved. The changed power refers to the power after the change of the laser cutting equipment. The reference power is adjusted according to the positive and negative conditions of the adjustment power, and the sum of the reference power and the adjustment power is calculated and used as the changed power, so as to facilitate subsequent analysis.

[0119] For example, when the laser cutting equipment cuts to the position with thickness deviation information, the reference power of the laser cutting equipment is adjusted to the changed power.

[0120] Step S107: Take the thickness deviation information, the changed power, and the cutting path as laser control information and output it to a preset laser cutting equipment to cut the blank.

[0121] The laser control information refers to the control information for controlling the laser cutting equipment to perform cutting. By combining the parameter information corresponding to the thickness deviation information, the cutting path, and the reference power, the laser control information is formed, so that when there are different thicknesses in a single blank, the laser power of the laser cutting machine can be adjusted in real time, thereby improving the cutting quality of laser cutting.

[0122] In Figure 1 In step S105 shown, in order to further ensure the rationality of the determination method of the thickness deviation information, it is necessary to perform a further separate analysis and calculation on the determination method of the thickness deviation information, which is specifically described in detail through the following steps.

[0123] Determination method of thickness deviation information:

[0124] Step S200: Determine the radian position on the cutting path according to the real-time cutting thickness, and take the radian position on the upper surface of the blank as the upper surface radian position, and the radian position on the lower surface of the blank as the lower surface radian position.

[0125] The radian position refers to the position on the blank where there is a radian that needs to be cut. The upper surface radian position refers to the position on the upper surface of the blank where there is a radian that needs to be cut. The lower surface radian position refers to the position on the lower surface of the blank where there is a radian that needs to be cut. By detecting the parameter changes of the infrared rays of two thickness detection devices, and through the infrared ray change detection, the surface and position of the corresponding blank are determined to obtain the radian position. The position on the surface of the laser head of the corresponding laser cutting machine on the blank and where there is a radian is taken as the upper surface radian position, and the position on the surface of the blank relative to the upper surface radian position and where there is a radian is taken as the lower surface radian position.

[0126] Step S201: Determine whether there are both an upper surface radian position and a lower surface radian position at the same vertical radian position on the cutting path. If not, jump to and execute Step S202. If so, jump to and execute Step S203.

[0127] By determining whether there are both an upper surface radian position and a lower surface radian position at the same vertical radian position on the cutting path, it is thus determined whether the real-time cutting thickness is consistent with the reference blank thickness.

[0128] Step S202: Take the upper surface radian position or the lower surface radian position as the thickness deviation position.

[0129] The thickness deviation position refers to the position on the blank where there is a thickness deviation that needs to be cut. When there are not both an upper surface radian position and a lower surface radian position on the cutting path, it indicates that the real-time cutting thickness is inconsistent with the reference blank thickness. Then, the single existing upper surface radian position or lower surface radian position is taken as the thickness deviation position.

[0130] Step S203: Take the radian position where both the upper surface radian position and the lower surface radian position exist as the marking position.

[0131] The marking position refers to the position marked on the blank surface. When there are both an upper surface radian position and a lower surface radian position on the cutting path, it indicates that the real-time cutting thickness is consistent with the reference blank thickness. Then, the radian position where both the upper surface radian position and the lower surface radian position exist is taken as the marking position.

[0132] Step S204: Determine the real-time radian thickness based on the marking position and the real-time cutting thickness.

[0133] The real-time radian thickness refers to the thickness where there is a radian on the real-time detected blank surface. By retrieving the thickness corresponding to the marking position from the real-time cutting thickness as the real-time radian thickness, it is thus convenient for subsequent analysis.

[0134] Step S205: Determine the thickness deviation position based on the consistency between the real-time radian thickness and the reference blank thickness and the radian position.

[0135] The thickness deviation position refers to the position on the blank surface where there is a thickness deviation. The thickness deviation position is determined by comparing the real-time arc thickness with the reference blank thickness and the arc position, facilitating subsequent analysis.

[0136] Step S206: Calculate the difference between the real-time arc thickness and the reference blank thickness as the thickness deviation value, and use the thickness deviation value and the thickness deviation position as the thickness deviation information.

[0137] The thickness deviation value refers to the deviation value between the real-time arc thickness and the reference blank thickness, which is calculated by subtracting the reference blank thickness from the real-time arc thickness. The thickness deviation information is formed by combining the thickness deviation value with the parameters corresponding to the thickness deviation position.

[0138] In step S205 shown above, to further ensure the rationality of the specific steps for determining the thickness deviation position based on the consistency between the real-time arc thickness and the reference blank thickness and the arc position, it is necessary to perform a further separate analysis and calculation on the specific steps for determining the thickness deviation position based on the consistency between the real-time arc thickness and the reference blank thickness and the arc position. The specific details are described in the following steps.

[0139] Specific steps for determining the thickness deviation position based on the consistency between the real-time arc thickness and the reference blank thickness and the arc position:

[0140] Step S300: Determine whether both the radian directions of the upper surface arc position and the lower surface arc position are the same and the radian of the upper surface arc position is not the same as that of the lower surface arc position. If so, jump to step S301. If not, jump to step S302.

[0141] By determining whether both the radian directions of the upper surface arc position and the lower surface arc position are the same and the radian of the upper surface arc position is not the same as that of the lower surface arc position, it is possible to determine whether there is a consistent situation between the real-time arc thickness and the reference blank thickness.

[0142] Step S301: Use the marked position where the real-time arc thickness is not the same as the reference blank thickness as the thickness deviation position.

[0143] When the radian directions of the upper surface radian position and the lower surface radian position are the same and the radians of the upper surface radian position and the lower surface radian position are the same, when the radian directions of the upper surface radian position and the lower surface radian position are different and the radians of the upper surface radian position and the lower surface radian position are the same, when the radian directions of the upper surface radian position and the lower surface radian position are different and the radians of the upper surface radian position and the lower surface radian position are different, it indicates that there is a discrepancy between the real-time radian thickness and the reference blank thickness. Then, the marked position where the real-time radian thickness and the reference blank thickness are inconsistent is taken as the thickness deviation position.

[0144] Step S302: Determine the radian distance according to the marked position and the cutting path.

[0145] The radian distance refers to the distance with a radian on the cutting path. When the radian directions of the upper surface radian position and the lower surface radian position are not the same while the radians of the upper surface radian position and the lower surface radian position are the same, it indicates that the thickness corresponding to the upper surface radian position and the lower surface radian position has changed. Then, the radian corresponding to the marked position is selected through the cutting path, and the linear coordinate distance is calculated through the position points between the cutting path and the radian, and the linear coordinate distance is taken as the radian distance.

[0146] Step S303: Determine the distance where the real-time radian thickness is consistent with the reference thickness value according to the radian distance and the real-time radian thickness as the radian reference distance.

[0147] The radian reference distance refers to the distance where the real-time radian thickness is consistent with the reference thickness value among the marked positions. By retrieving the respective thicknesses corresponding to the radian distance from the real-time radian thickness and selecting the distance corresponding to the thickness that is consistent with the reference thickness value from the respective thicknesses as the radian reference distance.

[0148] Step S304: Calculate the difference between the radian distance and the radian reference distance and take it as the radian deviation distance.

[0149] The radian deviation distance refers to the distance where the real-time radian thickness is consistent with the reference thickness value within the marked position. By calculating the difference between the radian distance and the radian reference distance and taking it as the radian deviation distance.

[0150] Step S305: Determine the radian deviation position according to the radian deviation distance and take the radian deviation position as the thickness deviation position.

[0151] The radian deviation position refers to the position corresponding to the radian deviation distance among the marked positions. By selecting the position corresponding to the radian deviation distance from the marked positions as the radian deviation position and taking the radian deviation position as the thickness deviation position.

[0152] In step S200 shown above, in order to further ensure the rationality of the specific steps after the radian position on the determined cutting path, it is necessary to conduct a further separate analysis and calculation on the specific steps after the radian position on the determined cutting path. Specifically, it is described in detail through Figure 2 the steps shown below.

[0153] Referring to Figure 2 , it also includes the specific steps after determining the cutting path according to the product shape:

[0154] Step S400: Obtain the image detection information of the blank and the drum specifications of the drum.

[0155] The image detection information refers to the image information corresponding to the blank to be cut. The image corresponding to the blank is taken in real time by an image detection device preset on the laser cutting equipment as the image detection information. The drum specifications refer to the dimensional parameter specifications corresponding to the drum for adhering dust. The dimensional specifications of the drum are input manually to determine the drum specifications.

[0156] Step S401: Form a reference blank image according to the blank specifications.

[0157] The reference blank image refers to the reference image corresponding to the blank to be cut. The dimensions, shape, color and other parameters of the blank are retrieved from the blank specifications and combined to form the reference blank image.

[0158] Step S402: Select the dust positions on the cutting path according to the comparison between the image detection information and the reference blank image.

[0159] The dust positions refer to the positions where dust exists on the blank to be cut. The color feature comparison between the image detection information and the reference blank image is used to obtain the positions where dust exists, and the positions where the cutting path passes through the dust are selected as the dust positions.

[0160] Step S403: Retrieve the reference drum width of the drum based on the drum specifications.

[0161] The reference drum width refers to the reference width corresponding to the drum for adhering dust. The axial length of the drum is retrieved from the drum specifications as the reference drum width.

[0162] Step S404: Determine the drum center position of the drum according to the reference drum width.

[0163] The drum center position refers to the center position corresponding to the drum for adhering dust. The value of half of the reference drum width is calculated, and the position on the drum axis is determined by the calculated value as the drum center position.

[0164] Step S405: Determine the shortest adhesion path of the drum according to the cutting path, the width of the reference drum, and the position of the drum center.

[0165] The shortest adhesion path refers to the shortest path for the drum to adhere to the dust on the cutting path. By taking the position of the drum center as the center of the drum running path and the width of the reference drum as the range for the drum to adhere to the dust, and then combining with the dust distribution on the cutting path to determine the shortest adhesion path.

[0166] Step S406: Take the shortest adhesion path as the drum control information and output it to the preset drum device to adhere to the dust.

[0167] The drum device refers to the device corresponding to the drum installed for adhering to the dust. By taking the parameters corresponding to the shortest adhesion path as the drum control information and outputting it to the preset drum device to adhere to the dust, the dust on the cutting path can be adhered when the drum runs along the shortest path, reducing energy consumption.

[0168] In Figure 2 In the shown step S405, in order to further ensure the rationality of the determination method of the shortest adhesion path, it is necessary to conduct a further separate analysis and calculation on the determination method of the shortest adhesion path, which is specifically described in detail through the following steps.

[0169] Determination method of the shortest adhesion path:

[0170] Step S500: Determine the drum area according to the drum specifications.

[0171] The drum area refers to the adhesion area corresponding to the drum for adhering to the dust. By retrieving the diameter and width of the drum from the drum specifications and then calculating the product of the width and the diameter as the drum area.

[0172] Step S501: Determine the product area based on the product shape.

[0173] The product area refers to the area of the product obtained after the blank is cut. The parameter obtained by combining the product shape and the corresponding dimensional parameters of the product shape is used as the product area.

[0174] Step S502: Determine whether the product area is less than the drum area. If yes, jump to step S503. If no, jump to step S505.

[0175] By determining whether the product area is less than the drum area, it can be judged whether the drum can directly complete the adhesion of the dust.

[0176] Step S503: Determine the maximum product width of the product according to the product shape.

[0177] The maximum product width refers to the maximum horizontal distance corresponding to the opposite sides of the product shape. When the product area is smaller than the drum area, it indicates that the drum can directly complete the adhesion of dust. Then, the position points of the opposite sides are retrieved according to the product shape, the distances between the relative position points are calculated, and the maximum distance selected from each distance is used as the maximum product width.

[0178] Step S504: Determine the rolling path of the drum device as the shortest adhesion path according to the maximum product width, the reference drum width, and the drum center position.

[0179] The straight-line path formed by making the maximum product width parallel to the reference drum width and the center of the maximum product width corresponding and overlapping with the drum center position, and then adhering to the dust on the cutting path is used as the shortest adhesion path. For example, when cutting a regular hexagon, by calculating the maximum width of the regular hexagon and making the drum parallel to the position of the maximum width, and then determining that the center of the maximum width corresponds to the center of the drum, so that the drum can adhere to the side lines of the regular hexagon when rolling.

[0180] Step S505: Select the initial adhesion path according to the dust position, and use the unselected path in the cutting path as other paths.

[0181] The initial adhesion path refers to the path where the drum initially adheres to the dust on the blank, and other paths refer to the paths on the cutting path where the dust has not been adhered after the drum runs along the initial adhesion path. When the product area is not less than the drum area, it indicates that the drum is not easy to directly complete the adhesion of dust. Then, the outermost path is retrieved from the cutting path, and the path with the dust position is selected as the initial adhesion path, and the other paths with the dust position are used as other paths.

[0182] Step S506: Calculate the horizontal distance between the initial adhesion path and other paths as the horizontal distance.

[0183] The horizontal distance refers to the horizontal distance between the initial adhesion path and other paths. The straight-line distance between the position points corresponding to the initial adhesion path and other paths is calculated as the horizontal distance. When there are other paths that do not conflict with the initial adhesion path and are perpendicular or intersect with the initial adhesion path, the endpoints of other paths close to the initial adhesion path are used as position points.

[0184] Step S507: Determine whether the horizontal distance is less than the reference drum width. If not, jump to execute Step S508. If so, jump to execute Step S509.

[0185] By determining whether the horizontal distance is less than the width of the reference roller, it is thus determined whether the roller can adhere to other paths when running the initial adhesion path.

[0186] Step S508: Take the cutting path as the shortest adhesion path.

[0187] When the horizontal distance is not less than the width of the reference roller, it indicates that the roller cannot adhere to other paths when running the initial adhesion path, then continue to take the cutting path as the shortest adhesion path.

[0188] Step S509: Determine the remaining path according to the initial adhesion path, the width of the reference roller, and the cutting path.

[0189] The remaining path refers to the path on the cutting path that still needs to adhere to dust. When the horizontal distance is less than the width of the reference roller, it indicates that the roller can adhere to other paths when running the initial adhesion path. Then, determine the range where the roller adheres to other paths through the initial adhesion path and the width of the reference roller, determine the position points corresponding to the range of adhering to other paths, and take the position points and the paths on other paths that have not been adhered to as the remaining path.

[0190] Step S510: Determine the remaining adhesion path according to the remaining path and the width of the reference roller, and take the initial adhesion path and the remaining adhesion path as the shortest adhesion path.

[0191] The remaining adhesion path refers to the path for the roller to adhere to dust on the remaining path. By placing one side of the reference roller width of the roller on the remaining path and the center position of the roller within the shape corresponding to the cut of the remaining path, then take the remaining path as the path for the center position of the roller to move and use it as the remaining adhesion path.

[0192] For example, when the product shape is a right trapezoid, take the side with more dust positions as the initial adhesion path and run it corresponding to the center position of the roller. Then, there is a need to swing the roller to adhere to the other sides of the right trapezoid. Then, the other sides start running from the adhered point to the remaining unadhered sides, and place the side of the roller on the unadhered side of the right trapezoid, with the center position of the roller inside the right trapezoid, so as to be able to adhere to the other sides as well.

[0193] In step S505 shown above, in order to further ensure the rationality of the specific steps for selecting the initial adhesion path according to the dust position, it is necessary to conduct a further separate analysis and calculation on the specific steps for selecting the initial adhesion path according to the dust position, which is specifically described in detail through the following steps.

[0194] Specific steps for selecting the initial adhesion path according to the dust position:

[0195] Step S600: Select a side path on the side of the product based on the cutting path and the product shape.

[0196] The side path refers to the path located on the side of the product shape. The path corresponding to the side of the product in the cutting path is retrieved as the side path.

[0197] Step S601: Overlap the side path with the center position of the roller, and determine the roller adhesion range according to the reference roller width and the side path.

[0198] The roller adhesion range refers to the range where the roller can adhere on the side path. By overlapping the center position of the roller with the side path and passing through the reference roller width, the adhered range during the operation along the side path is used as the roller adhesion range.

[0199] Step S602: Determine the dust quantity at each dust position according to the roller adhesion range and the dust position.

[0200] The dust quantity refers to the number of dust positions within the roller adhesion range. The number of dust positions within the roller adhesion range corresponding to each side path is used as the dust quantity.

[0201] Step S603: Select the side path with the largest dust quantity as the initial adhesion path based on the dust quantity.

[0202] When the dust quantities are different, the side path with the largest dust quantity is used as the initial adhesion path, so that the dust on the cutting path can be adhered faster.

[0203] Step S604: When and only when the dust quantities are the same, determine the inclined path according to the cutting path and the reference cutting method preset in the laser cutting device.

[0204] The reference cutting method refers to the method of moving and cutting by the laser cutting device, which is formed by being preset and stored by the operator. The inclined path refers to the path that is not a straight-line cut in the reference cutting method. When the dust quantities are the same, the path parameter that is not a straight-line cut is selected from the program parameters corresponding to the reference cutting method of the laser cutting device for the cutting path as the inclined path.

[0205] For example, when there is an oblique line in the product shape, the X-axis and Y-axis programs need to be run simultaneously in the laser cutting device, and the path corresponding to this program is used as the inclined path.

[0206] Step S605: Determine the distance parallel to the reference roller width between the two endpoints of the inclined path as the maximum adhesion distance according to the inclined path.

[0207] The maximum adhesion distance refers to the maximum distance at which the inclined path can adhere to dust. It is calculated by retrieving the position points at both ends of the inclined path from the inclined path and calculating the horizontal and vertical distances between the two position points as the maximum adhesion distance.

[0208] Step S606: Determine whether the maximum adhesion distance is less than the reference drum width. If yes, jump to and execute Step S607. If no, jump to and execute Step S608.

[0209] By determining whether the maximum adhesion distance is less than the reference drum width, it is thus determined whether the drum can adhere to the dust present on the inclined path while running in the vertical or horizontal direction.

[0210] Step S607: Determine the initial adhesion path according to the position of the center of the maximum adhesion distance.

[0211] When the maximum adhesion distance is less than the reference drum width, it indicates that the drum can adhere to the dust present on the inclined path while running in the vertical or horizontal direction. Then, the position corresponding to the center of the maximum adhesion distance is made to correspond to the center position of the drum, and the path perpendicular to the maximum adhesion distance is used as the initial adhesion path.

[0212] Step S608: Use the inclined path as the initial adhesion path.

[0213] When the maximum adhesion distance is not less than the reference drum width, it indicates that the drum cannot adhere to the dust present on the inclined path while running in the vertical or horizontal direction. Then, the inclined path is used as the initial adhesion path.

[0214] In Figure 2 In Step S406 shown, in order to further ensure the rationality of the specific steps after using the shortest adhesion path as the drum control information, it is necessary to perform a further separate analysis and calculation on the specific steps after using the shortest adhesion path as the drum control information. Specifically, it is described in detail through the Figure 3 steps shown.

[0215] Referring to Figure 3 , it also includes the specific steps after using the shortest adhesion path as the drum control information:

[0216] Step S700: Obtain the real-time drum image of the drum and form a virtual drum model based on the real-time drum image.

[0217] The real-time roller image refers to the image corresponding to the roller when it adheres to dust, and the image of the roller adhering to dust on the blank is captured in real time by an image detection device preset on the laser cutting equipment as the real-time roller image. The virtual roller model refers to the virtual model corresponding to the roller when it adheres to dust, and the model formed by inputting the real-time roller image into a modeling component preset on the laser cutting equipment is used as the virtual roller model.

[0218] Step S701: Determine the dust occupancy ratio according to the virtual roller model, the preset roller color, and the roller center position.

[0219] The dust occupancy ratio refers to the occupancy ratio of dust on the left and right sides of the roller center position. By retrieving the area where the color corresponding to the dust exists and the area of the cylindrical side corresponding to the roller color from the virtual roller model, and calculating the quotient of the area where the color corresponding to the dust exists and the area of the cylindrical side corresponding to the roller as the dust occupancy ratio. The roller color refers to the color of the cylindrical side of the roller for adhering to dust, which is formed by being preset and stored by the operator in advance.

[0220] Step S702: Determine the side with the minimum dust occupancy ratio on the left and right sides of the roller as the maximum adhesion position according to the dust occupancy ratio, the virtual roller model, and the roller center position.

[0221] The maximum adhesion position refers to the position on the roller that can adhere the most dust. By bisecting the area of the cylindrical side of the roller based on the roller center position, the position with the minimum dust occupancy ratio on the left and right sides of the roller on the virtual roller model is used as the maximum adhesion position.

[0222] Step S703: Determine the dust distribution position according to the shortest adhesion path and the dust position.

[0223] The dust distribution position refers to the position where the dust is distributed on the left and right sides with the shortest adhesion path as the center. By taking the shortest adhesion path as the center and selecting the dust positions on the left and right sides of the shortest adhesion path from the dust positions as the dust distribution position.

[0224] Step S704: Based on the mutual correspondence between the maximum adhesion position and the dust distribution position to form the roller adhesion information.

[0225] When the maximum adhesion position and the dust distribution position are in a relative position, the roller is controlled to rotate 180 degrees so that the maximum adhesion position and the dust distribution position can overlap and correspond to each other. The angle parameter of the rotation when the maximum adhesion position and the dust distribution position on the roller correspond to each other is used as the roller adhesion information.

[0226] Step S705: Add the roller adhesion information to the roller control information to form new roller control information, and output the roller control information to the roller device.

[0227] By adding the parameters corresponding to the drum adhesion information to the drum control information to form new drum control information and outputting it to the drum device, it is possible to make the maximum adhesion position correspond to the dust distribution position, and thus improve the efficiency of the drum in adhering to dust.

[0228] At Figure 3 In step S705 shown, in order to further ensure the rationality of the specific steps after adding the drum adhesion information to the drum control information to form new drum control information, it is necessary to perform a further separate analysis and calculation on the specific steps after adding the drum adhesion information to the drum control information to form new drum control information, which will be specifically described in detail through the following steps.

[0229] It also includes the specific steps after adding the drum adhesion information to the drum control information to form new drum control information:

[0230] Step S800: Based on the dust position, determine whether there is dust within the radian position. If not, jump to execute step S801. If so, jump to execute step S802

[0231] By judging whether there is dust within the radian position through the dust position, it is possible to determine whether the drum control information needs to be adjusted.

[0232] Step S801: Continue to execute step S705.

[0233] When there is no dust within the radian position, it indicates that the drum control information does not need to be adjusted, so continue to jump to execute step S705.

[0234] Step S802: Determine the arc top position and radian type according to the real-time cutting thickness, reference blank thickness, and radian position. The radian type with the real-time cutting thickness less than the reference blank thickness is regarded as the concave arc radian, and the radian type with the real-time cutting thickness greater than the reference blank thickness is regarded as the convex arc radian.

[0235] The arc top position refers to the position of the arc top corresponding to the radian on the blank surface. The radian type refers to the arc type of the radian position on the blank surface, and the arc type includes the concave arc type and the convex arc type. When there is dust within the radian position, it indicates that the drum control information needs to be adjusted, so the radian type is determined by comparing the real-time cutting thickness with the reference blank thickness. The radian type with the real-time cutting thickness less than the reference blank thickness is regarded as the concave arc radian, and the radian type with the real-time cutting thickness greater than the reference blank thickness is regarded as the convex arc radian, and the position corresponding to the maximum or minimum real-time cutting thickness of the radian position is detected by the thickness detection device as the arc top position.

[0236] Step S803: Determine whether the cutting path is at the apex position of the convex arc radian. If yes, jump to and execute Step S804. If no, jump to and execute Step S805.

[0237] By determining whether the cutting path is at the apex position of the convex arc radian, it is judged whether the shortest adhesion path in the drum control information needs to be replaced.

[0238] Step S804: Continue to jump to and execute Step S705.

[0239] When the cutting path is at the apex position of the convex arc radian, it indicates that the shortest adhesion path in the drum control information does not need to be replaced, so continue to jump to and execute Step S705.

[0240] Step S805: Determine the convex radian path position according to the apex position and the cutting path.

[0241] The convex radian path position refers to the path position corresponding to the convex radian where the cutting path is located. When the cutting path is not at the apex position of the convex arc radian, it indicates that the shortest adhesion path in the drum control information needs to be replaced. Then, taking the apex position of the convex radian as the center, and taking the positions corresponding to the cutting paths on the left and right sides of the apex position as the convex radian path positions.

[0242] Step S806: Select the relative side of the convex radian path position located at the apex position based on the drum center position as the convex radian drum adhesion position.

[0243] The convex radian drum adhesion position refers to the position corresponding to the dust adhered to the convex radian position of the drum. By selecting the side opposite to the convex radian path position based on the drum center position from the drum as the convex radian drum adhesion position. For example, when the cutting path is on the left side of the convex radian, the right side position in the advancing direction of the drum path needs to be selected, so as to facilitate the adhesion of the dust on the left side of the convex radian.

[0244] Step S807: Determine the adjusted adhesion path according to the convex radian drum adhesion position and the shortest adhesion path.

[0245] The adjusted adhesion path refers to the path for the drum to adhere to the dust after adjustment. By adding the path corresponding to the convex radian drum adhesion position to the shortest adhesion path to form a new path as the adjusted adhesion path.

[0246] Step S808: Replace the shortest adhesion path in the drum control information with the adjusted adhesion path to form a new drum control information and output it to the drum device.

[0247] By replacing the corresponding parameters of the shortest adhesion path in the drum control information by adjusting the adhesion path to form new drum control information and outputting it to the drum device, it is possible to adhere to the convex arc position with dust on the cutting path.

[0248] In step S808 shown above, in order to further ensure the rationality of the specific steps before judging whether the cutting path is at the apex position of the convex arc radian, it is necessary to perform a further separate analysis and calculation on the specific steps before judging whether the cutting path is at the apex position of the convex arc radian, which will be specifically described in detail through the following steps.

[0249] Specific steps before judging whether the cutting path is at the apex position of the convex arc radian also include:

[0250] Step S900: Obtain the reference deviation area between the radian position and the blank surface.

[0251] The reference deviation area refers to the area where there is a deviation between the blank surface and the concave arc apex position. By combining the deviation parameters between the concave radian position and the blank surface detected by an infrared device in the thickness detection device, the reference deviation area is formed.

[0252] Step S901: Select the side with the least dust occupancy ratio on the drum as the inclined adhesion position based on the dust occupancy ratio.

[0253] The inclined adhesion position refers to the position where the drum adheres to dust after tilting. By selecting the side with the least dust occupancy ratio on the drum as the inclined adhesion position.

[0254] Step S902: Retrieve the position of the path within the concave radian position based on the cutting path as the concave radian path position.

[0255] The concave radian path position refers to the path position corresponding to the cutting path within the concave radian. By taking the apex position of the concave radian as the center and taking the positions corresponding to the cutting paths on the left and right sides of the apex position as the concave radian path positions.

[0256] Step S903: Determine the tilt angle according to the reference deviation area and the concave radian path position.

[0257] The tilt angle refers to the angle at which the drum needs to be tilted. By determining the position point between the hypotenuse and the shortest side of the right angle for the concave arc path position, and selecting the deviation distance from the reference deviation area where the vertical position of the concave arc path reaches the blank surface as the shortest right-angle side, then taking the distance between the concave arc path position and the position point corresponding to the arc on the blank surface as the hypotenuse, and the horizontal distance from the position point where the arc appears on the blank surface to the concave arc path position as the other right-angle side, the angle parameter obtained by combining the shortest right-angle side, the hypotenuse, and the other right-angle side is used as the tilt angle.

[0258] Step S904: Determine the initial tilt path based on the drum center position, the tilt adhesion position, and the shortest adhesion path.

[0259] The initial tilt path refers to the initial path when the drum is tilted. By tilting and adhering at the tilt adhesion position in the shortest adhesion path, and taking the path corresponding to the operation of the drum center position as the initial tilt path.

[0260] Step S905: Determine whether the cutting path is located at the apex position of the concave arc.

[0261] By determining whether the cutting path is located at the apex position of the concave arc, it is possible to know the angle adjustment situation of the drum.

[0262] Step S906: If it is located, add the initial tilt path and the tilt angle to the drum control information to form new drum control information.

[0263] When the cutting path is located at the apex position of the concave arc, it means that the drum needs to be tilted to adhere to the dust at the apex. Then add the parameters corresponding to the initial tilt path and the tilt angle to the drum control information to form new drum control information.

[0264] Step S907: If it is not located, determine the horizontal rotation angle of the drum based on the drum center position, the tilt adhesion position, and the concave arc path position.

[0265] The horizontal rotation angle refers to the angle at which the drum rotates left and right. When the cutting path is not located at the apex position of the concave arc, it means that the drum needs to be tilted to the path inside the apex for adhesion. Then, by rotating around the drum center position, the angle corresponding to the alignment of the tilt adhesion position and the concave arc path position is used as the horizontal rotation angle.

[0266] For example, if the tilt adhesion position and the concave arc path position are on the same side, the horizontal rotation angle is 0 degrees. If the tilt adhesion position and the concave arc path position are on opposite sides, the horizontal rotation angle is 180 degrees.

[0267] Step S908: Determine the changed adhesion path based on the inclined adhesion position and the shortest adhesion path.

[0268] The changed adhesion path refers to the path by which the roller adheres to dust after change. A new path is formed by adding the path corresponding to the inclined adhesion position to the shortest adhesion path as the changed adhesion path.

[0269] Step S909: Replace the shortest adhesion path in the roller control information with the changed adhesion path, and add the inclination angle and the horizontal rotation angle to form new roller control information and output it to the roller device.

[0270] By replacing the corresponding parameters of the shortest adhesion path in the roller control information with the changed adhesion path, and adding the parameters corresponding to the inclination angle and the horizontal rotation angle to the roller control information to form new roller control information and output it to the roller device, the dust with concave curvature can be adhered by the roller.
