Abstract
Description
Technical Field
[0001] This invention relates to the field of laser scribing equipment technology, and in particular to an adaptive adjustment laser scribing control method and device. Background Technology
[0002] In the field of laser scribing, especially in roll-to-roll film processing, existing laser scribing equipment mostly adopts a single-head light-emitting structure, equipped only with a basic motion axis system, and lacks a secondary axis system for error compensation and multi-directional adjustment, making it difficult to meet the high-efficiency and precise processing requirements of modern production.
[0003] The existing technology has the following drawbacks: First, it has poor compatibility, as the single-head structure cannot be compatible with multiple lasers and can only meet the needs of a single processing scenario; second, it has low processing efficiency, as it cannot achieve multi-head parallel processing and is difficult to match the needs of mass production; third, it lacks processing flexibility, as it lacks a Y-axis adjustment structure and cannot achieve on-demand cutting processing for roll materials; fourth, it has low scribing accuracy, as it lacks a dedicated error compensation axis system and is difficult to correct scribing deviations caused by equipment operation and uneven film boundaries; and fifth, it has limited functionality and cannot adapt to special processing scenarios such as angular deviations between the scribing requirement X-axis and the actual X-axis.
[0004] In summary, existing laser marking equipment has significant shortcomings in terms of compatibility, efficiency, accuracy, and functional diversity, and there is an urgent need for an adaptive laser marking device to solve these problems. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings by providing an adaptive adjustment laser scribing control method and apparatus.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adaptive adjustment laser scribing control method, applied to an adaptive adjustment laser scribing device, comprising the following steps: S1. The first mold is scribed and marked; the camera vision system identifies the boundary position between the film material and the adsorption platform to complete the positioning; the laser head scribes a vertical line along the first Y-axis and marks the point to complete the first mold processing. S2. Determine if the offset exceeds the threshold. The camera vision system detects whether the offset of the mark point of the previous model exceeds the set field of view threshold. If yes, return to step S1, re-identify the membrane boundary and start the first model processing. If no, proceed to step S3. S3. Subsequent mold processing and marking: The camera vision system identifies the mark points of the previous mold as a reference to complete the positioning. The starting mark points of the first and last lines of the previous mold are M1 and M2, and the ending mark points are M3 and M4. The starting point of the next mold is on the straight line M3M4. The angle of the first line of the next mold is consistent with the straight line M1M3, and the subsequent lines are parallel to the first line. The laser head marks the lines and marks new mark points, and the cycle continues.
[0007] Furthermore, in step S2, after the previous model marks 4 marks, the multi-axis moving component moves the camera and the marking device to the theoretical coordinate position of the marks. If the marks can be identified, it is determined that the offset is not beyond the visual range; if they cannot be identified, it is determined that the offset exceeds the threshold, and the process is reset.
[0008] Furthermore, in step S1, the vertical line is located at the center of the field of view of the camera's vision system. In step S3, the field of view threshold is half of the camera's field of view, and the offset detection is based on a preset original coordinate system. The system pre-stores the theoretical coordinates of the mark point.
[0009] Furthermore, when the Y-axis of the scribing requirement is at an angle to the actual Y-axis, visual compensation is used in conjunction with the first Y-axis to compensate for the difference between the actual scribing starting point and the theoretical starting point, and the XY-axis moving speed of the scribing platform is matched to complete the corresponding scribing process.
[0010] Furthermore, the visual compensation process is as follows: a preset original coordinate system with zero deviation of the film material is used; the offset angle of the film material is identified during the first mold processing; the acute angle of the right triangle corresponding to the known scribing length and offset angle is obtained through the side-angle relationship to obtain the XY axis displacement, and then the moving speed of the multi-axis moving component is matched.
[0011] Furthermore, in steps S1 and S2, the camera vision system constructs a virtual reference plane based on the membrane boundary and mark points, projects the real-time line trajectory onto this plane and compares it with the theoretical trajectory to help determine whether the offset exceeds the threshold.
[0012] Furthermore, the virtual reference plane coordinate calibration establishes a two-dimensional rectangular coordinate system with the geometric center of the quadrilateral formed by the four mark points as the origin, and calibrates the difference between the actual and theoretical coordinates of each mark point to ensure comparison accuracy.
[0013] Another technical solution adopted in this invention is: an adaptive laser scribing device, comprising an adsorption platform, a multi-axis moving assembly, a roll material conveying assembly, and a camera vision system; The adsorption platform is used to fix the film material to be processed. The multi-axis moving component is located above the adsorption platform. Each axis system is driven independently to adapt to multi-directional scribing and error compensation. The roll material conveying assembly drives the roll material to continuously pass over the adsorption platform to complete the processing.
[0014] Furthermore, the multi-axis moving assembly includes a first X-axis, a first platform, two parallel second platforms, and corresponding axis systems; The first X-axis slides and supports the first platform. Two second platforms are each connected to the first platform via the second X-axis. Each second platform is equipped with the first Y-axis, and the laser head is mounted on the first Y-axis. Through multi-axis collaboration, angle compensation and precise line drawing are achieved.
[0015] Furthermore, the roll material conveying assembly includes an active conveying roller, a driven conveying roller, and a tension adjusting mechanism, the tension adjusting mechanism maintaining stable film conveying tension; The device also includes a mechanical beam splitting module for individual control of multiple beams, adapting to the needs of simultaneous processing of multiple beams.
[0016] The beneficial effects of this invention are reflected in: 1. High positioning accuracy: Through mark point positioning, virtual reference plane comparison and deviation reset mechanism, combined with the offset detection of the preset coordinate system, positioning deviation during membrane material transportation and processing is effectively avoided, ensuring continuous scribing accuracy. 2. High adaptability: Through visual compensation combined with multi-axis collaborative fine-tuning, it can accurately adapt to the angle deviation between the scribing requirement Y-axis and the actual Y-axis, and complete the accurate scribing of different angles without complicated debugging, adapting to a variety of membrane material processing scenarios. 3. High processing efficiency: The device adopts a dual second platform multi-head collaborative structure, combined with a mechanical beam splitting module and tension stabilization mechanism, to achieve continuous batch processing of membrane materials, balancing efficiency and processing consistency. 4. The structure is simple and highly practical. The components of the device are rationally laid out, the shaft system design is adapted to the processing requirements, the method and process are clear and can be implemented, reducing the equipment debugging and maintenance costs, and its practicality is outstanding.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] This invention discloses an adaptive laser scribing control method and device. The method can accurately realize continuous scribing processing of film materials. By using mark point positioning, visual compensation, and virtual reference plane comparison, it solves problems such as positioning deviation, poor angle adaptability, and inaccurate inter-mold connection in traditional scribing. The device provides hardware support for the above method. It has a compact structure, strong adaptability, and can meet the needs of multi-head collaborative processing. The specific implementation method is described in detail below.
[0021] The adaptive laser scribing control method disclosed in this embodiment is applied to an adaptive laser scribing device, enabling continuous and precise scribing of film materials. It is particularly suitable for film material processing scenarios with high requirements for scribing accuracy and inter-mold connection accuracy, such as... Figure 1 As shown, the specific steps are as follows: S1. The first die is scribing and marking. The camera vision system identifies the boundary position between the film material and the adsorption platform to complete the positioning. The laser head scribing a vertical line along the first Y-axis and marking the point completes the first die processing. After the laser scribing device is started, the roll material conveying assembly transports the film material to be processed to the adsorption platform. The adsorption platform activates its adsorption function to firmly fix the film material and prevent it from shifting or wrinkling during processing. Subsequently, the camera vision system (an industrial CCD camera is used in this embodiment, electrically connected to the image processing module) is activated to identify the boundary position between the film material and the adsorption platform. The image processing module analyzes the boundary contour to complete the initial positioning of the film material, ensuring that the laser head scribing position is aligned with the preset processing area of the film material. After positioning, the laser head, driven by the multi-axis moving assembly, draws a vertical line along the first Y-axis (this vertical line is used for auxiliary positioning in subsequent mold processing and also serves as the reference line for the first mold processing), and marks four points (positioning marks) at preset positions on the film material. These four marks correspond to M1, M2, M3, and M4 in subsequent steps, and are evenly distributed at the four corners of the first mold processing area, thus completing the first mold processing. Figure 1 As shown.
[0022] S2. Determine if the offset exceeds the threshold. The camera vision system detects whether the offset of the mark point of the previous model exceeds the set field of view threshold. If yes, return to step S1, re-identify the membrane boundary and start the first model processing. If no, proceed to step S3.
[0023] Furthermore, the vertical line drawn in the first mold processing step is precisely located at the center of the field of view of the camera vision system. The field of view of the camera vision system is set to 1mm. This setting ensures that the vertical line is always within the camera's recognizable range during subsequent mold processing, providing a basis for positioning accuracy. At the same time, the field of view threshold used in the subsequent deviation reset step is set to half of the camera's field of view, i.e., 0.5mm. The basis for the detection of offset is the original coordinate system preset by the system. This original coordinate system is the standard coordinate system when the film material is laid out with zero deviation. The theoretical coordinates of 4 mark points are pre-stored in the system for comparison and judgment of subsequent offsets.
[0024] S3. Subsequent mold processing and marking. The camera vision system identifies the mark points of the previous mold as a reference to complete the positioning. The starting mark points of the first and last lines of the previous mold are M1 and M2, and the ending mark points are M3 and M4. The starting point of the next mold's line drawing is located on the straight line M3M4. The angle of the first line of the next mold is consistent with the straight line M1M3, and the subsequent lines are parallel to the first line. The laser head draws the lines and marks new mark points, and the process is repeated.
[0025] After the first mold processing is completed, the adsorption platform releases its grip on the membrane material, and the roll conveyor assembly moves the membrane material forward a specified distance (this distance is consistent with the single-mold processing length of the membrane material and is preset by the system). Once in position, the adsorption platform restarts its gripping action to fix the membrane material in place. Subsequently, the camera vision system activates, using the four mark points established during the previous mold processing as a reference to complete the positioning of the current membrane material. Figure 4 As shown, the specific positioning and scribing rules are as follows: the starting mark points of the first and last lines of the previous mold are M1 and M2, and the ending mark points of the first and last lines of the previous mold are M3 and M4. The first and last lines refer to the first and last scribing lines drawn in the previous mold processing. The starting point of the scribing for the current and next molds is on the straight line M3M4. The angle of the first scribing line of the next mold is consistent with the angle of the straight line M1M3. All subsequent scribing lines drawn in the next mold are parallel to the first scribing line, ensuring the continuity and consistency of scribing between molds. After positioning and angle calibration, the laser head, driven by the multi-axis moving component, scribing follows the preset scribing trajectory and marks four new mark points at the preset position of the current mold, serving as the positioning reference for the next mold processing. This process is repeated sequentially to achieve continuous batch scribing processing of the film material.
[0026] During continuous cyclic processing, the camera vision system monitors the positions of the four mark points from the previous mold in real time, determining whether their offset exceeds the set field-of-view threshold (0.5mm). When the mark point offset exceeds this threshold, it indicates that the current film material positioning deviation is large. If processing continues, the scribing accuracy will be unqualified. At this time, the processing flow automatically resets to the initial mold processing steps. The adsorption platform releases its adsorption, the roll material conveying assembly adjusts the film material position, and the camera vision system re-identifies the boundary position between the film material and the adsorption platform. The initial positioning, vertical line scribing, and mark point marking are then completed again, and the first mold processing flow is started to ensure the accuracy of subsequent processing. Furthermore, the specific detection method for mark point offset is as follows: after the previous mold is completed and 4 mark points are marked, the multi-axis moving component drives the camera vision system and laser scribing device to move together to the theoretical coordinate position of the mark point pre-stored by the system; if the camera vision system can clearly identify the 4 mark points, it means that the offset of the mark points has not exceeded the camera's visual range, and it is determined that the offset has not exceeded the threshold, so the next mold processing can be started normally; if the camera vision system cannot identify the mark points (i.e. the mark points are outside the camera's field of view), it is determined that the offset has exceeded the threshold, and the process is immediately reset.
[0027] To adapt to scribing requirements at different angles, when there is an angular deviation between the scribing requirement's Y-axis and the actual Y-axis, visual compensation combined with multi-axis collaborative fine-tuning is used to make up for the difference between the actual scribing starting point and the theoretical scribing starting point. The movement speed of the multi-axis moving components is matched, where the X-axis movement speed is the movement speed of the first platform 22 along the X-axis, and the Y-axis movement speed is the movement speed of the second platform 23 along the Y-axis. Finally, the precise scribing processing at the corresponding angle is completed, avoiding scribing misalignment caused by angular deviation.
[0028] Specifically, the detailed process of visual compensation is as follows: The system pre-sets an original coordinate system with zero deviation in membrane material placement as the benchmark for angle compensation and displacement calculation; during the first mold processing, the camera vision system 4 synchronously identifies the offset angle of the membrane material (i.e., the angle between the actual placement direction of the membrane material and the original coordinate system); given the scribing length of each mold (i.e., the hypotenuse length of the scribing trajectory) and an acute angle of the right triangle corresponding to the membrane material offset angle (i.e., the offset angle itself), the displacement corresponding to the X-axis and Y-axis is calculated through the side-angle relationship of the right triangle (sine and cosine theorems). Then, based on the displacement and the preset scribing speed, the movement speed of the X-axis and Y-axis in the scribing platform is matched to ensure that the scribing trajectory is completely consistent with the preset requirements, such as... Figure 5 As shown. For example: the system sets the scribing length L per die, the scribing time t, and the visual detection shows the film material placement offset angle θ, then: X-axis movement: X = L * sinθ, the speed of movement along the X-axis: X / t, Y-axis movement: Y = L * cosθ, speed of movement along the Y-axis: Y / t.
[0029] To further improve the accuracy of offset determination, during the initial and subsequent mold processing, the camera vision system constructs a virtual reference plane based on the identified membrane boundary and the four marked points. During the scribing process, the camera vision system acquires the scribing trajectory of the laser head in real time and projects this real-time trajectory onto the constructed virtual reference plane. It then compares this trajectory with the preset theoretical scribing trajectory. By comparing the difference, it helps determine whether the scribing offset exceeds the set field of view threshold. This dual calibration, together with the mark point offset detection, further improves the scribing accuracy. Furthermore, the coordinate calibration of the virtual reference plane is achieved based on four mark points: a two-dimensional rectangular coordinate system is established with the geometric center of the quadrilateral formed by the four mark points as the origin (this coordinate system is adapted to the system's preset original coordinate system); the camera vision system collects the actual coordinates of the four mark points respectively and compares them with the theoretical coordinates pre-stored in the system, calculating the difference between the actual coordinates and theoretical coordinates of each mark point; the virtual reference plane is calibrated based on this difference to correct the positional deviation of the virtual reference plane, ensuring the accuracy of the comparison between the real-time line trajectory and the theoretical trajectory, and providing support for the accurate determination of the offset.
[0030] The adaptively adjustable laser scribing device disclosed in this embodiment, such as... Figure 2-3As shown, the laser scribing control method used to achieve the above-mentioned adaptive adjustment provides hardware support for the implementation of the method. Its specific structure and function are as follows: The device mainly includes an adsorption platform 1, a multi-axis moving component 2, a roll material conveying component 3, and a camera vision system 4. The components work together to achieve continuous and precise scribing of the membrane material. Among them, the adsorption platform 1 adopts an air flotation adsorption structure (vacuum adsorption structure is optional) to fix the membrane material to be processed, ensuring that the membrane material does not shift or wrinkle during the scribing process; the upper surface of the adsorption platform 1 remains flat and is adapted to the conveying path of the roll material conveying component 3, ensuring that the membrane material can be stably conveyed to the top of the adsorption platform 1 and fixed. The multi-axis moving assembly 2 is located above the adsorption platform 1 and is fixedly connected to the device frame. Each axis system adopts an independent drive method (such as servo motor drive), which can realize multi-directional precise movement, adapt to multi-directional scribing and angle error compensation requirements, and provide precise drive for the scribing trajectory of the laser head. Its specific structure includes a first X-axis 21, a first platform 22, two parallel second platforms 23 and corresponding axis systems. The first X-axis 21 adopts a linear guide rail + servo motor drive structure, is horizontally mounted on the device frame, and its extension direction is consistent with the conveying direction of the roll material conveying assembly 3. It is used to drive the first platform 22 to move along the X-axis direction, realizing the scribing trajectory drive of the laser head in the X-axis direction. The first platform 22 is slidably supported on the slider of the first X-axis 21 and can move smoothly along the X-axis direction under the drive of the first X-axis 21. The upper surface of the first platform 22 remains horizontal, for mounting two parallel second platforms 23. The two second platforms 23 are arranged side by side on the upper surface of the first platform 22, and the structures of the two second platforms 23 are completely identical. Each second platform 23 is connected to the first platform 22 through a corresponding second X-axis, wherein the extension direction of the second X-axis is parallel to the first X-axis 21. Each second platform 23 is equipped with a first Y-axis, and the laser head is mounted on the slider of the first Y-axis, which can move along the Y-axis direction under the drive of the first Y-axis. Through the coordinated work of the above multi-axis structure, the laser head can move in multiple directions in the X-axis and Y-axis directions. At the same time, through multi-axis coordinated fine adjustment, angle deviation compensation is achieved to ensure the accuracy of the scribing trajectory. The two parallel second platforms 23 can be equipped with two laser heads, enabling multi-head simultaneous processing and improving processing efficiency.
[0031] The camera vision system 4 includes an industrial CCD camera, an image processing module, and a mounting bracket. The mounting bracket is fixedly connected to the multi-axis moving component 2 and can move together with the multi-axis moving component 2. The camera's shooting direction is towards the membrane material above the adsorption platform 1, which is used to realize membrane material boundary recognition, mark point recognition, position calibration, and offset detection. The acquired image signal is transmitted to the image processing module, which performs analysis and comparison to achieve adaptive adjustment.
[0032] In this embodiment, the adaptive laser scribing device first transports the film material to be processed to the adsorption platform 1 via the roll material conveying assembly 3. The adsorption platform 1 then initiates adsorption to fix the film material. Subsequently, the camera vision system 4 identifies the boundary between the film material and the adsorption platform 1, completing the initial positioning. The multi-axis moving assembly 2 drives the laser head to scribble a vertical line along the first Y-axis and mark 4 points, completing the first mold processing. After the first mold processing is completed, the adsorption platform 1 releases the adsorption, and the roll material conveying assembly 3 moves the film material to the next processing position and re-fixes it. The camera vision system 4 uses the mark points of the previous mold as a reference for positioning, completes the scribing according to preset rules, and marks new mark points, and processes the material in a cyclical manner. During the processing, the camera vision system 4 detects the mark point offset and scribing trajectory in real time, and uses the virtual reference plane for comparison to assist in judging the deviation. If the deviation exceeds the threshold, the process is reset. When there is an angular deviation, it is achieved through visual compensation combined with multi-axis collaborative fine adjustment.
