Abstract

A computer graphics distribution device performs an ordered classification of a marking pattern to be marked, and calculates a maximum stroke that can be moved according to the dividing line. According to this method, it moves along the X-axis direction, and the selected point of the selected line is found to find the maximum stroke that each selected point can move. Therefore, these maximum strokes form a zone Z above and below the line. In this zone Z, a moving line passing through the zone Z is obtained, which is the trajectory of the movement of the sliding table relative to the marking galvanometer. Then along each point on the moving line, calculate the distance between the point and the selected line along the Y axis, that is, the marking offset distance, which is the marking galvanometer of the laser marking machine at each point of the selected line. The point at which you must move to mark. With this method, laser marking can be performed. The advantage is that the trajectory of the movement of the sliding table relative to the marking galvanometer is a relatively gentle curve or even a straight line, so that a relatively fixed moving speed can be maintained, so the marked line is quite flat. Furthermore, the marking of one line is continuously completed in one operation, so the line has no trace of the continuation of the continuation point, and shows the appearance of the line segment which is smooth and close to the planning. The case is also suitable for dividing the original picture into several different areas, performing the above marking operation for each area, and moving the sliding table relative to the laser marking machine when entering from one area to another area. Did not stop, and maintain a smooth path.

Description

Laser marking system for continuous marking of separate lines

This creation is about laser marking, which mainly uses laser marking in the form of online segments, especially a laser marking system with continuous marking.

The laser marking machine is applied to the laser beam to achieve marking, material removal, cutting or engraving after applying the laser beam through the lens to achieve high focusing. The marking object is typically placed on a sliding table. The motor system is then used to control the movement and rotation of the slide table, and the slide table is moved to a position suitable for marking to perform a marking operation.

Due to the limited marking range of the laser marking machine, the laser marking machine must first divide the marking pattern to be marked into multiple parts when processing large marking objects or large marking patterns, and then adjust the laser. The marking machine aligns and marks the different corresponding positions of the processed object, and splices out the complete figure. The processing methods of the prior art all manually divide and sort the marking graphics manually, and then manually control the alignment of the sliding table for marking, and it is difficult to avoid the situation of incomplete seams. Therefore, for large-scale marking graphics that are too complicated, manual training is very time-consuming and laborious, and even complicated to be able to perform manually.

In the improved technique, the linear pattern can be marked again and again, and there is no case where the above pattern has a broken line, but if the figure is not a smooth curve but has a sharp corner, the slide table at this time When it is displaced relative to the marking machine, it must be accelerated and decelerated. However, this operation affects the entire operating procedure.

Therefore, this case hopes to propose a new automatic laser marking graphic line marking system to solve Prior to technical defects. In addition to automatically dividing the marking pattern, the marking can be improved in consideration of the special condition of the adjacent bending portion, and the marked pattern can achieve high quality effect to avoid marking. The graphics create tearing gaps, distortions, or visually abnormal dashed lines.

Therefore, the purpose of this creation is to solve the above-mentioned problems in the prior art. In this creation, a laser marking system for continuous marking of a line is proposed, which has the advantage that the trajectory of the sliding table relative to the movement of the marking galvanometer is The smooth curve is even a straight line, so it can maintain a relatively constant moving speed, so the marked line is quite flat. Furthermore, the marking of one line is continuously completed in one operation, so the line has no trace of the continuation of the continuation point, and shows the appearance of the line segment which is smooth and close to the planning.

In order to achieve the above objective, the present invention proposes a laser marking system for continuous marking of a line, comprising: a laser marking machine capable of emitting a laser beam for marking, and a lightning emitted by the laser marking machine The beam of light can be projected onto a marking object for marking, and the marking object presents a marking pattern, wherein the marking galvanometer moves to the desired marking point in the X and Y directions, and the laser light is projected out. To achieve the purpose of marking; a sliding table on which the marking object is placed, the laser marking machine can irradiate the laser beam onto the marking object, and the marking object forms a laser beam marking a graphic; wherein the sliding table moves to the required marking point in the X and Y directions to receive the laser beam projected by the laser marking machine for marking purposes; a motor system is mainly used to control the The sliding table moves in the X and Y directions, so the sliding table can be moved to a position suitable for marking; a computer device can determine the entire marking space and the storage machine according to the position of the laser marking machine and the marking direction Space coordinates of the station; a laser hit A controller for controlling the laser marker, the a motor system and the slide table for performing a required marking operation on the marking object; a graphic marking planner for marking the laser marking machine for each line in the marking pattern formed by the line The path is planned in such a manner that for each line in the marking pattern, the sliding table is first moved relative to the laser marking machine by a smooth path, and then the laser is adjusted for each point in the smoothing path. The marking galvanometer of the standard machine moves to the required marking point in the X and Y axis directions for marking. A computer graphics distribution device, connected to the computer device and the laser marking controller, can divide a marking pattern into a plurality of lines.

I would like to discuss the structure of the case, the functions and advantages that can be produced, and the pattern. As long as it is a figure composed of lines, a preferred embodiment of the present invention will be described in detail below.

Please refer to FIG. 1 to FIG. 6 to show the graphic line marking planning system of the present invention, which is mainly used on the laser marking machine system, and includes the following components: a laser marking machine 10, which can emit lasers. The beam is used for marking. The laser beam emitted by the laser marking machine 10 can be projected onto a marking object 100 for marking, and the marking object 100 presents a marking pattern. The marking oscillating mirror 12 is moved to the required marking point in the X and Y axis directions, and the laser light is projected to achieve the marking purpose.

A slide table 20 on which the marking object 100 is placed. The laser marking machine 10 can illuminate a laser beam onto the marking object 100 and form a pattern of laser beam marking at the marking object 100. Generally, the graphic is quite beautiful, and has a rich texture, which is not achievable by printing or printing by a general printer. The slide table 20 is moved to the required marking point in the X and Y axis directions to receive the laser beam projected by the laser marking machine 10 for marking purposes.

Therefore, in order to project the laser beam to the required marking point during marking, the sliding table 20 and the marking oscillating mirror 12 must move in the X and Y directions. Therefore, the movement trajectory of the slide table 20 relative to the marking galvanometer 12 must first be planned according to the marked pattern.

A motor system 30 is mainly used to control the movement of the slide table 20 in the X and Y axis directions, so that the slide table 20 can be moved to a position suitable for marking.

A computer device 50 can determine the space of the entire marking space and the storage machine according to the position of the laser marking machine 10 and the marking direction.

The computer device 50 can mark a two-dimensional graphic of the entire marking space and receive a marking graphic 40 input by the user. Therefore, according to the geometric position of the marking pattern 40 in the two-dimensional space, the point coordinates of the marking pattern 40 corresponding to the two-dimensional space are calculated. The computer device 50 coordinates the coordinates of the two-dimensional space Outgoing.

A laser marking controller 60 is provided for controlling the laser marking machine 10, the motor system 30 and the sliding table 20 to perform a required marking operation on the marking object 100.

A computer graphics distribution device 70, connected to the computer device 50 and the laser marking controller 60, can divide a marking pattern 40 into a plurality of lines, as shown in FIG. 2, FIG. 3 and FIG. The un-lined figure, FIG. 3A and FIG. 3B show the pattern after the line is divided, and FIG. 4A and FIG. 4B show another line-sharing mode. Therefore, there may be different ways of dividing the line and it does not affect the implementation of the case.

A graphic marking planner 75 performs the planning of the marking path of the laser marking machine 10 for each of the lines divided by the computer graphics dividing device 70, so that the entire marking path can achieve the highest efficiency and Can be closest to the original graphic. The so-called highest efficiency means that the fastest time or the shortest stroke can achieve the purpose of marking.

The situation is illustrated in Figure 2, where the pattern is divided into two lines 80, 85. The marking plan in this case is illustrated as follows; the X and Y coordinates are set for the graphic, and the selected point 81 is planned for the selected line 80, and for each selected point 81, the marking galvanometer 12 is above and below the Y axis. Calculating the maximum stroke 83 that can be moved, that is, when the center point of the marking galvanometer 12 is aligned with a selected point 81 of the selected line, the marking galvanometer 12 can project a laser on the Y-axis. The maximum range of the beam. According to this method, the X-axis direction is moved, and the selected point 81 of the selected line 80 is found to find the maximum stroke that each selected point can move. Therefore, these maximum strokes form a zone Z above and below the line, as shown in FIG. 5. Shown in it.

In this zone Z, a moving line 84 passing through the zone Z is obtained, which is the trajectory of the movement of the table 20 relative to the marking galvanometer 12. Preferably, the moving line is a smooth curve, and more preferably the moving line is a straight line.

Along each point 81 on the selected line 80, the distance from the point to the selected line along the Y-axis, ie, the offset offset distance, is calculated, which is the marking galvanometer 12 of the laser marking machine at the selected line. Each point 81 of 80 must be moved to mark the point.

Then, according to the result of the calculation in the above column, the information of the movement path of the slide table 20 relative to the marking galvanometer 12 (ie, the moving line 84) and the position of the galvanometer offset marking is transmitted to the laser marking controller 60. Based on the data, the laser marking controller 60 determines the relative position of the sliding table 20 controlled by the motor system 30 and the marking galvanometer 12 in the laser marking machine 10, and then the laser is hit by the laser. The labeling machine 10 marks the corresponding area on the marking object 100. Preferably, the laser marking machine 10 is first moved along the selected point 81 of the selected line 80. At each selected point, the application of the marking galvanometer 12 is adjusted according to the calculated marking offset distance. The movement on the X and Y axes is marked. When the laser marking machine 10 is processed along the selected line 80, the slide 20 is simultaneously moved along the planned moving line 84, thereby accelerating the overall Marking speed and maintaining good processing quality.

Each line 80, 85 divided by the computer graphics distribution device 70 is marked according to the steps listed above. That is to complete the marking operation. There may be multiple ways to divide the line divided by the computer graphics distribution device 70, but these different methods do not affect the final marking result.

Another embodiment of the present invention is shown in Fig. 6, in which the L-shaped line 90, in the present case, can be seen that the moving line 84 is a line having a smooth chamfer at which compensation must be made.

Another embodiment of the present invention is shown in FIG. 7, wherein the original image is divided into a plurality of different regions 110, and the marking operation is performed for each region 110, and when entering the other region 110 from one region 110, The movement of the slide table 20 relative to the laser marking track 10 is not stopped, and a smooth path is maintained as much as possible, so that the interruption point of the entire marking pattern 40 can be minimized, so that the overall marking speed can be accelerated.

The advantage of the present case is that a computer graphics distribution device is used to make an ordered line of the marking pattern to be marked, and the maximum stroke that can be moved is calculated according to the dividing line. According to this method, it moves along the X-axis direction, and the selected point of the selected line is found to find the maximum stroke that each selected point can move. Therefore, these maximum strokes form a zone Z above and below the line. In this zone Z, a moving line 84 passing through the zone Z is obtained, which is the trajectory of the movement of the table 20 relative to the marking galvanometer 12. And along each point on the moving line, calculate the distance between the point and the selected line along the Y axis, that is, the marking offset distance, which is the marking oscillating mirror 12 of the laser marking machine at the selected line 80. Each point 81 must be moved to mark the point. With this method, laser marking can be performed. This has the advantage that the trajectory of the movement of the slide table 20 relative to the marking galvanometer 12 is a relatively gentle curve or even a straight line, so that a relatively constant moving speed can be maintained, so that the marked line is relatively flat. Furthermore, the marking of one line is continuously completed in one operation, so the line has no trace of the continuation of the continuation point, and shows the appearance of the line segment which is smooth and close to the planning.

In summary, the humanized and automated thoughtful design of this case is quite in line with actual needs. The specific improvement of the existing defects is obviously a breakthrough improvement advantage compared with the prior art, and it has an improvement in efficacy and is not easy to achieve. The case has not been disclosed or disclosed in domestic and foreign literature and market, and has complied with the provisions of the Patent Law.

The detailed description above is a detailed description of one of the possible embodiments of the present invention, and the embodiment is not intended to limit the scope of the patents, and the equivalent implementations or modifications that are not included in the spirit of the present invention should be included in The patent scope of this case.
