Abstract
Description
Technical Field
[0001] The present invention belongs to the field of laser processing technology, and relates to a laser scanning system and a laser scanning method, and in particular to a laser scanning system and a method for filling a pattern with multiple laser scanning strategies. Background Art
[0002] When filling graphics with laser, the original processed graphics and the actual processed graphics are often not completely consistent after comparison. For example, when the filling spacing or filling line width of laser processing is inconsistent, color difference will appear when connecting a single processed graphic, resulting in processing defects.
[0003] At present, there are several ways to perform laser scanning processing on non-solid filled graphics: 1. Fixed angle parallel scanning method. This scanning method is physically limited and is filled with at least two continuous parallel scanning lines, resulting in at least two joints in the processing result. 2. Single radial center scanning method. Through various methods, a relatively suitable radial center point is found for equiangular radial scanning, so as to obtain a better scanning path based on the minimum number of joints; however, this single center scanning method has two disadvantages: (1) The filling density is high in areas close to the radial center, resulting in poor processing effect; (2) Because the processing range of the galvanometer is limited by hardware, the scanning strategy must be optimized to reduce the cost of hardware selection. For example: if a long non-solid rectangle is processed with a single radial scanning center, the length of the required scanning line may exceed the processing range of the galvanometer. The disadvantage of a single radial center is that the filling density is high in areas close to the radial center, resulting in poor processing effect. It can only achieve better processing effect when used on regular circular ring graphics. Summary of the invention

[0012] Optimally, the processing file includes a computer-aided design file and an image file of the processing graphics of the workpiece surface to be subjected to the laser scanning process.
[0013] Optimally, the at least one galvanometer scanning mode has a fixed scanning motion rule corresponding to the galvanometer.
[0014] Furthermore, the first scanning path is that the galvanometer completely covers the processing file with the fixed scanning action rule of the at least one galvanometer scanning mode.
[0015] Optimally, the scanning path of the at least one equidistant range has a relative relationship with the at least one galvanometer scanning mode.

It should be noted that the drawings are for illustration only and do not represent the actual size or quantity of the components. Some details may not be fully drawn to simplify the drawings.
[0027] First, please refer to Figure 1 , which is a block diagram of the laser scanning system of the present application. When implemented, the laser scanning system of the present application includes: a workpiece to be subjected to a laser scanning process, a laser source 110, a galvanometer drive unit 120 (for driving the scanning action of the galvanometer 121), an input unit 130 (for inputting a processing file 131), and a storage unit 140 (for storing at least one galvanometer scanning mode 141). Among them, the input unit 130 does not limit the input method, and can be an input interface on a processing machine or an external device (such as a laptop computer). The processing file 131 is a computer-aided design (CAD) file or image file containing processing graphics of the workpiece surface to be subjected to a laser scanning process. At least one galvanometer scanning mode 141 has a fixed scanning action rule corresponding to the galvanometer 121, for example: equal spacing (such as Figure 2 (a) (b) or equal angles (as shown in Figure 2 The scanning action rules shown in (c) in FIG. Figure 2As shown, a schematic diagram of three galvanometer scanning modes is listed, and each scanning mode has its own filling line distribution rule. When the present application is implemented, the storage unit 140 is not limited to a number of scanning modes.
[0028] The control unit 150 is coupled to the laser source 110 , the galvanometer driving unit 120 , the input unit 130 and the storage unit 140 ; the control unit 150 receives a processing file 131 input from the input unit 130 and at least one galvanometer scanning mode 141 input from the storage unit 140 .
[0029] The control unit 150 calculates the scanning action for driving the galvanometer driving unit 120 according to the processing file 131 and the at least one galvanometer scanning mode 141, and the scanning action of the galvanometer 121 is implemented as a first scanning path that completely covers the processing file 131. The first scanning path is that the galvanometer 121 completely covers the processing pattern of the processing file 131 on the surface of the workpiece to be subjected to the laser scanning process by the fixed scanning action rule of the at least one galvanometer scanning mode 141; the scanning action rule for the at least one galvanometer scanning mode 141 to completely cover the processing pattern may only require one scanning action rule, or may be a combination of multiple scanning action rules, and the processing pattern is split according to actual needs and the corresponding galvanometer scanning strategy is executed for each split area. For example, in one embodiment of the present invention, when the storage unit 130 inputs two galvanometer scanning modes (equal spacing and equal angle) to the control unit 150, and the control unit 150 determines that the processing file 131 needs to be split into two areas for scanning based on the processing file 131 and the two galvanometer scanning modes, one area in the processing file 131 corresponds to the equal spacing galvanometer scanning mode and is completely covered, and another area in the processing file 131 corresponds to the equal angle galvanometer scanning mode and is completely covered. In another embodiment of the present invention, when the storage unit 130 inputs two galvanometer scanning modes (equal spacing and equal angle) to the control unit 150, and the control unit 150 determines that the processing file 131 does not need to be split into two areas for scanning based on the processing file 131 and the two galvanometer scanning modes, the control unit 150 selects the equal spacing galvanometer scanning mode or the equal angle galvanometer scanning mode to completely cover the processing file 131 according to the actual situation.
[0030] The control unit 150 then adjusts the galvanometer scanning path of each scanning area according to the processing file 131 and the first scanning path to calculate a second scanning path. The second scanning path divides the processing file into at least one scanning path with an equal spacing range to obtain a better scanning path. To further explain, the control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface with an equal spacing range as much as possible by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing graphics. Next, the control unit 150 captures the portion that needs to be processed on the first scanning path as the second scanning path according to the processing file 131, that is, the most uniform path is used to execute the final galvanometer scanning path to obtain a better scanning path.
[0031] Finally, the control unit 150 outputs a galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs a switch command 152 to the laser source 110 for performing laser scanning processing. In practice, when the control unit 150 controls the galvanometer driving unit 120 to move to the corresponding scanning path of at least one equally spaced range, the switch command 152 output by the control unit 150 to the laser source 110 is a laser on command, and when the galvanometer driving unit 120 moves to the non-scanning path, the switch command 152 output by the control unit 150 to the laser source 110 is a laser off command.
[0032] When implemented, the present application also provides a laser scanning method, which includes: the control unit 150 is coupled to the laser source 110, the galvanometer drive unit 120, the input unit 130 and the storage unit 140. The control unit 150 receives the processing file 131 input by the input unit 130 and the at least one galvanometer scanning mode 141 input by the storage unit 140.
[0033] The scanning process is as follows: Step 1: The control unit 150 first selects a fixed logic scanning mode according to the processing file 131 and the at least one galvanometer scanning mode 141, such as the aforementioned equal spacing (such as Figure 2 (a) (b) or equal angles (as shown in Figure 2) as shown in (c) in the figure. Step 2: Cover the selected at least one galvanometer scanning mode 141 on the processing graphics of the processing file 131. Step 3: Repeat the above actions until all the processing graphics of the processing file 131 are covered by at least one galvanometer scanning mode 141. The control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface as much as possible within an equal spacing range by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing graphics. Step 4: The control unit 150 captures the part that needs to be processed on the first scanning path according to the processing file 131 as the second scanning path, that is, the most evenly partitioned path is used to execute the final galvanometer scanning path to obtain a better scanning path.
[0034] Finally, the control unit 150 outputs the galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs the switch command 152 to the laser source 110 to perform laser scanning processing on the workpiece.
[0035] The application example of the present invention is as follows: Embodiment 1: Figure 3 As shown, the processing file 131 is a filled, track ring laser scanning processing pattern. The track ring filling pattern is composed of two galvanometer scanning modes 141, including two equiangular radiations on both sides and a 90-degree equidistant parallel scanning scanning area.
[0036] Step 1: The control unit 150 receives the processing file 131 transmitted from the input unit 130 and the at least one galvanometer scanning mode 141 transmitted from the storage unit 140. In this embodiment, the at least one galvanometer scanning mode 141 includes an equiangular radiation galvanometer scanning mode and a 90-degree equidistant parallel galvanometer scanning mode. Step 2: Cover the selected at least one galvanometer scanning mode 141 on the processing figure of the processing file 131. Step 3: Repeat the above actions, including two equiangular radiation scanning modes on both sides and a 90-degree equidistant parallel scanning scanning mode, until all processing figures of the processing file 131 are covered by the at least one galvanometer scanning mode 141, and the control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface as much as possible within an equidistant range by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing figure; Figure 3As shown, the first scanning path is to completely cover the processing file with these filling lines (scanning routes) distribution rules. Step 4: The control unit 150 captures the part to be processed on the first scanning path according to the processing file 131 as the second scanning path, that is, the path with the most uniform partition is used to execute the final galvanometer scanning path to obtain a better scanning path, such as Figure 3 Thicker lines shown.
[0037] Finally, the control unit outputs the galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs the switch command 152 to the laser source 110, so as to perform laser scanning processing on the workpiece. When the control unit 150 controls the galvanometer driving unit 120 to move to the corresponding scanning path of the at least one equally spaced range (such as Figure 3 The switch command 152 output by the control unit 150 to the laser source 110 is a laser on command; and when the galvanometer drive unit 120 moves to the non-scanning path (such as Figure 3 ), the switch command output by the control unit 150 to the laser source 110 is a laser off command.
[0038] Embodiment 2: Figure 4 As shown, the processing file 131 is a laser scanning processing pattern of a filled rectangular ring. The rectangular ring filling pattern is composed of these galvanometer scanning patterns 141, including four equiangular radiations at the corners, a 90-degree equidistant parallel scanning, and a 0-degree equidistant parallel scanning scanning area.
[0039] Step 1: The control unit 150 receives the processing file 131 transmitted from the input unit 130 and the at least one galvanometer scanning mode 141 transmitted from the storage unit 140. In this embodiment, the at least one galvanometer scanning mode 141 includes an equiangular radiation galvanometer scanning mode, a 90-degree equidistant parallel galvanometer scanning mode, and a 0-degree equidistant parallel scanning scanning mode. Step 2: Cover the selected at least one galvanometer scanning mode 141 on the processing graphics of the processing file 131. Step 3: Repeat the above actions, including four equiangular radiations at the corners, a 90-degree equidistant parallel scanning, and a 0-degree equidistant parallel scanning scanning mode, until all the processing graphics of the processing file 131 are covered by the at least one galvanometer scanning mode 141, and the control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface as much as possible within an equidistant range by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing graphics; Figure 4As shown, the first scanning path is to completely cover the processing file with these filling lines (scanning routes) distribution rules. Step 4: The control unit 150 captures the part to be processed on the first scanning path according to the processing file 131 as the second scanning path, that is, the path with the most uniform partition is used to execute the final galvanometer scanning path to obtain a better scanning path, such as Figure 4 Thicker lines shown.
[0040] Finally, the control unit outputs the galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs the switch command 152 to the laser source 110, so as to perform laser scanning processing on the workpiece. When the control unit 150 controls the galvanometer driving unit 120 to move to the corresponding scanning path of the at least one equally spaced range (such as Figure 4 The switch command 152 output by the control unit 150 to the laser source 110 is a laser on command; and when the galvanometer drive unit 120 moves to the non-scanning path (such as Figure 4 ), the switch command output by the control unit 150 to the laser source 110 is a laser off command.
[0041] Embodiment 3: Figure 5 As shown, the processing file 131 is a laser scanning processing pattern of an S-shaped filling pattern. The S-shaped filling pattern is composed of two galvanometer scanning modes 141, including two equiangular radiations on both sides and a 45-degree equidistant parallel scanning scanning area.
[0042] Step 1: The control unit 150 receives the processing file 131 transmitted from the input unit 130 and the at least one galvanometer scanning mode 141 transmitted from the storage unit 140. In this embodiment, the at least one galvanometer scanning mode 141 includes an equiangular radiation galvanometer scanning mode and a 45-degree equidistant parallel galvanometer scanning mode. Step 2: Cover the selected at least one galvanometer scanning mode 141 on the processing figure of the processing file 131. Step 3: Repeat the above actions, including two equiangular radiation scanning modes on both sides and a 45-degree equidistant parallel scanning scanning mode, until all processing figures of the processing file 131 are covered by the at least one galvanometer scanning mode 141, and the control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface as much as possible within an equidistant range by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing figure; Figure 5As shown, the first scanning path is to completely cover the processing file with these filling lines (scanning routes) distribution rules. Step 4: The control unit 150 captures the part to be processed on the first scanning path according to the processing file 131 as the second scanning path, that is, the path with the most uniform partition is used to execute the final galvanometer scanning path to obtain a better scanning path, such as Figure 5 Thicker lines shown.
[0043] Finally, the control unit outputs the galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs the switch command 152 to the laser source 110 to perform laser scanning processing on the workpiece. In practice, when the control unit 150 controls the galvanometer driving unit 120 to move to the corresponding scanning path of at least one equal spacing range (such as Figure 5 The switch command 152 output by the control unit 150 to the laser source 110 is a laser on command; and when the galvanometer drive unit 120 moves to the non-scanning path (such as Figure 5 ), the switch command output by the control unit 150 to the laser source 110 is a laser off command.
[0044] Embodiment 4: Figure 6 As shown, the processing file 131 is a laser scanning processing pattern of multiple patterns (filled patterns arranged in a ring shape with small patterns). The filled patterns arranged in a ring shape with small patterns are composed of two galvanometer scanning modes 141, including four equiangular radiations at the corners and a 90-degree equidistant parallel scanning scanning area.
[0045] Step 1: The control unit 150 receives the processing file 131 transmitted from the input unit 130 and the at least one galvanometer scanning mode 141 transmitted from the storage unit 140. In this embodiment, the at least one galvanometer scanning mode 141 includes an equiangular radiation galvanometer scanning mode and a 90-degree equidistant parallel galvanometer scanning mode. Step 2: Cover the selected at least one galvanometer scanning mode 141 on the processing graphics of the processing file 131. Step 3: Repeat the above actions, including four equiangular radiations in the corners and a 90-degree equidistant parallel scanning mode, until all processing graphics of the processing file 131 are covered by the at least one galvanometer scanning mode 141, and the control unit 150 controls the adjacent galvanometer scanning paths to perform laser scanning on the workpiece surface as much as possible within an equidistant range by adjusting the center position of each scanning area and the scanning rules, and calculates the first scanning path that can completely cover the processing graphics; Figure 6As shown, the first scanning path is to completely cover the processing file with these filling lines (scanning routes) distribution rules. Step 4: The control unit 150 captures the part to be processed on the first scanning path according to the processing file 131 as the second scanning path, that is, the path with the most uniform partition is used to execute the final galvanometer scanning path to obtain a better scanning path, such as Figure 6 Thicker lines shown.
[0046] Finally, the control unit outputs the galvanometer scanning command 151 to the galvanometer driving unit 120 according to the second scanning path, and outputs the switch command 152 to the laser source 110 to perform laser scanning processing on the workpiece. In practice, when the control unit 150 controls the galvanometer driving unit 120 to move to the corresponding scanning path of at least one equal spacing range (such as Figure 6 The switch command 152 output by the control unit 150 to the laser source 110 is a laser on command; and when the galvanometer drive unit 120 moves to the non-scanning path (such as Figure 6 The non-bold area shown in FIG. 1 ) is a laser off command output by the control unit 150 to the laser source 110.
[0047] The above embodiments illustrate that the technical features of this case are that the number of scanning centers is not limited, the position of the scanning centers is not limited, and a single graphic can be used with multiple scanning strategies. Among them, a single graphic may be a double closed geometry (such as a runway ring, a rectangular ring), a single closed geometry (S-shaped) and a multi-closed geometry, etc., and the implementation and application of the present invention does not limit the type of graphics.
[0048] In the past, when laser processing annular graphics, the scanning strategy of a single scanning center point was usually used to perform galvanometer scanning, which easily affected the processing quality. This technology splits the processing graphics according to actual needs and executes the corresponding galvanometer scanning strategy for each area after the split. The galvanometer scanning strategy of multiple scanning center points is used to fill the graphics and the most uniform path is used to execute the final galvanometer scanning path to achieve a better processing effect.
[0049] The technology in this case also solves the problem of poor processing results caused by the scanning range of the galvanometer being limited by hardware. For processing long filled rectangles, the longest scanning line length of the conventional galvanometer scanning mode with a single scanning center is much longer than the multi-center scanning method in this case. Moreover, reducing the scanning line length (distance) can reduce hardware requirements and reduce machine hardware costs. If, in the application scenario of synchronous processing with a large axis and a galvanometer, the planning flexibility of the galvanometer moving path can be improved.
[0050] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
