Description

Laser marking partitioning device

The invention relates to a laser marking device, in particular to a laser marking partitioning device for performing laser marking using an image partitioning bonding method.

The conventional laser marking machine forms marks, patterns and the like on the surface of the workpiece by laser, and has high precision, high speed, and permanent marking, compared with the conventional mechanical engraving or chemical etching forming method. Advantages, therefore, in the industrial, especially in the integrated circuit industry, the high precision and high volume of IC marking required, so laser marking technology and equipment is important in the industry.

The general laser marking machine includes a laser source, a control card and a galvanometer module, wherein the laser source is used for emitting laser light, and is characterized by fast speed and high precision, so that the laser marking machine The laser source is generally a pulsed laser. With the use of a control card, the frequency of the pulsed laser, the pulsed laser switch and the pulsed laser power can be adjusted in real time to meet the user's needs; the control card is used to Commands are issued to command and control the operation of the galvanometer module and the laser source; the galvanometer module is used to adjust the imaging quality of the laser light on the surface of the object, and the optical module includes the X-direction galvanometer module and the Y direction. The galvanometer module, the actual marking is to adjust the rotation angle of the two galvanometer modules to control the position of the laser spot, but the rotation angle of the galvanometer module has its specific range, resulting in the laser marking processing range. Limited, in order to achieve a wide range of marking applications, the splicing method will be used to divide the large-scale graphics into several small areas, and the actual marking is one area and one area for marking, and These areas are spliced, so-called partition marking, to meet the needs of both fast and wide range.

Referring to FIG. 1, FIG. 1 is a schematic diagram of a trajectory of a laser source after being irradiated on a workpiece by a conventional laser marking machine. In FIG. 1, the component symbol 90 is an indication of an expected marking, and refers to a graphic that the user wants to form on the workpiece 9. The expected marking pattern 90 is stored in an electronic file on the control card (not shown in FIG. 1). In the control card, the electronic file with the expected marking pattern 90 is converted into a signal that the laser source (not shown in FIG. 1) can read to drive the laser source for marking. When marking, the laser source will form multiple laser spots on the workpiece 9. The collection of laser points at different times constitutes the laser source trajectory 91. Figure 1 shows the marking process from start to finish. The scatter diagram of the laser source trajectory 91, the marking process starts from the marking starting point 91S, and ends at the marking end point 91E, but in order to ensure that the laser source trajectory 91 is actually marking the process, and the expected marking pattern 90 The marking starting point 91S is consistent with the marking end point 91E, and the delay parameter is designed in the control card. After waiting for the galvanometer module to operate for a period of time, the laser point reaches the marking starting point 91S and marking of the expected marking pattern 90. At the end point 91E, the marking process is repeated or the marking process is stopped. During the marking process, the laser source is kept moving at the same speed, but the laser source is always before the marking start point 91S or after the marking end point 91E. Keep it open, so that it accelerates from zero speed to machining speed, or decelerates from machining speed to zero speed. It is easy to gather in unit distance at the slower starting point in the area where the traveling speed is lower than the machining speed. More laser energy, let The marking pattern 92 looks like a match head, and when marking the partition, the actual marking pattern 92 with the shape of the match head causes the boundary of the section to be particularly conspicuous, so that the entire drawing is likely to have defects in the connecting part. .

In addition, because the control card sends commands and the oscillating mirror module (not shown in Figure 1), the actual operation is not synchronized, and the servo is behind and the laser switch is behind, causing the marking to fail to hit the target position, and there is no boundary at the switching light. The gaps are processed, resulting in obvious seams in the partition. For example, it is expected that at the starting point of the marking pattern 90, the servo lag will cause the galvanometer module to be late, so that the marking starting point is 91S. Compared with the starting point of the expected marking pattern 90, the laser light emission is more slowly than the servo backward amount; while the laser source trajectory 91E is later than the end point of the expected marking pattern 90, the target starting point is not processed; At the end point, the servo is behind and the actual light-off point is forward. When the laser is off, the actual light-off point is backward. The laser light is more frequent than the servo backward. The actual light-off point is closer to the command. The point is further ahead and the target end point is not processed.

Furthermore, another conventional technique is an image mosaic marking method, as shown in FIG. 2, and FIG. 2 is a schematic diagram of a conventional laser marking machine using a splicing method for marking, when the user proposes an expected marking pattern 98. The control card in the laser marking machine will split the expected marking pattern 98 into two parts, that is, the first part of the marking pattern 98A and the second part of the expected marking pattern 98B, when the marking process is actually performed, the laser source A laser source trajectory first portion 99A and a laser source trajectory second portion 99B are formed on the workpiece according to the predicted marking pattern first portion 98A and the predicted marking pattern second portion 98B, wherein the two have overlapping portions of the laser source trajectory 99C. The laser source track overlap portion 99C performs two laser markings to mark the less clear places in the original marking process to make it clearer, and finally forms the actual marking pattern 99. Through the overlap of the laser source trajectory to join the partition pattern, the marking is clear, but the overlapping of the laser source trajectory 99C is easy to align, so the 99C in the overlap of the laser source trajectory is easy to connect and the marking error, and no When the start and end of the acceleration/deceleration are processed, the match head pattern represented by the actual marking pattern 92 in Fig. 1 is likely to occur in the laser source track overlapping portion 99C.

In view of the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to use the laser marking partitioning device to not only correct the partition marking image through repeated partition marking, but also to determine the partition by computer using a visual device. The good image of the standard image greatly reduces the mistake of human discrimination Poor, the correction of the galvanometer module data, interpolation calculations to take into account the default value, to avoid connection errors and marking errors.

Another purpose of the creation is to use the laser marking partitioning device provided by the present invention to instantly feedback the determination result of the zone marking image, and the user can instantly input the request data according to the warning signal to adjust the marking zone. The target image can be adjusted instantly without waiting for the entire marked image to be completed.

In order to enable your review committee to have a better understanding and recognition of the structural purpose and efficacy of this creation, please refer to the detailed description of the illustration as follows. The technical means and functions used to achieve the purpose of the present invention will be described below with reference to the drawings, and the embodiments listed in the following drawings are only for the purpose of explanation, and are to be understood by the reviewing committee, but the technical means of the present invention are not limited to the enumerated figure.

First, please refer to FIG. 3. FIG. 3 is a schematic diagram showing the internal components of the laser marking zone bonding device 1 provided by the present invention. The laser marking zone bonding device 1 is used for zone marking on the workpiece 14, which comprises a laser marking device 11, a vision device 12 and a laser source device 13. The laser marking partitioning device 1 can be a casing (not shown) for covering the laser marking device 11, the visual device 12 and the laser source device 13, the laser marking device 11, and the visual device. 12 and the laser source device 13 are all disposed in the casing of the laser marking partitioning device 1 in a modular manner. The devices may be spatially independent, but the three devices are electrically connected. In addition, the laser source device 13 is electrically connected to the workpiece 14 in a wireless manner, and the vision device 12 is electrically connected to the workpiece 14 . In the embodiment of the present invention, the laser marking device 11 is used to drive the laser source device 13, and the laser source device 13 receives the preset values of the interface parameters transmitted by the laser marking device 11 after the workpiece 14 is The partitioning is performed on the partitioning device, and the visual device 12 is configured to capture the partition marking image on the workpiece 14 and perform comparison to return the compared image discriminating result to the laser marking device 11, and the laser marking device The detailed operation of the device 11, the vision device 12, and the laser source device 13 on the workpiece 14 is as follows.

After the user turns on the laser marking zone bonding device 1, the graphic is drawn first, and the laser marking zone bonding device 1 follows the graphics and the request data transmitted by the laser marking device 11. The first partition marking is performed in the workpiece 14. In the present creation, the partition marking refers to transferring a certain area in the graphic to the workpiece 14 by laser transfer, in one embodiment of the present creation. If the graphic is an English word "Word", the laser marking partitioning device 1 divides the graphic with Word into two partitions, the first partition is "Wor" and the second partition is "rd". The laser marking zone bonding device 1 will perform a "Wor" on the workpiece 14 for the first partition. The time for marking the first partition is defined as the first time in this embodiment; at the next time, that is, the second time, the "rd" is marked on the workpiece 14 for the second partition. It should be noted that, for the graphic, the number of partitions on the graphic is not within the scope of the present invention, and how the graphics are partitioned can also be defined by the user. Therefore, in another embodiment, the English word is used. The first partition of "Word" may be "Wo", and the second partition may be "ord". The principle of partitioning is that there is a need for repeated characters or graphics between the first partition and the second partition; In an embodiment, the first partition is "Wor" and the second partition is "rd", and the repeated characters or graphics between the two are "r"; in another embodiment, the first partition is "" Wo" and the second partition are "ord", then the repeated characters or graphics between the two are "o".

After the first zone is marked on the workpiece 14, the vision device 12 in the laser marking zone bonding device 1 compares the marking image on the workpiece with the predetermined image stored in the visual device, and The image discriminating result obtained after the comparison is transmitted back to the laser marking device 11, and the laser marking device 11 sends a warning message, the warning message includes a normal prompt, a leak prompt and a match head prompt, and the warning message can be It is a kind of signal message. For example, the normal prompt is a continuous flashing green light, the leak prompt is a continuous flashing yellow light, and the red light of the match head prompts continuously flashing. The user can make a request for the information to the laser marking device 11 at the next time according to the content of the warning message. In an embodiment, when the warning message received by the user is a normal prompt, that is, the image discrimination result is that the marking pattern is consistent with the actual pattern, the laser marking partitioning device 1 is requested to continue working. In another embodiment, when the warning message received by the user is a leak indication, it indicates that some characters or patterns between the marking pattern and the actual pattern cannot be connected, and then, The laser marking partitioning device 1 proposes a request material for increasing the laser energy; in another embodiment, when the warning message received by the user is a match head prompt, it indicates that the applied laser energy is excessive and the marking pattern is caused. If it is larger than the actual pattern, there will be a match head pattern in the marking pattern. At this time, the laser marking partitioning device 1 will be reduced. The request data of the laser energy is sent to the laser marking partitioning device 1 for a plurality of requests, and if the user obtains the normal information, and the laser marking partitioning device 1 is requested to continue working, The above adjustment procedure can be ended, and the laser marking partitioning device 1 will then operate by itself to complete the overall marking image of the graphic "Word", that is, the first partition "Wor" and the second partition in "Word" "rd" completes the joint, which is the so-called partition joint.

Next, please refer to FIG. 4. FIG. 4 is a schematic diagram showing the laser marking partition bonding apparatus 1 provided by the present invention when performing partition marking. It is to be noted that, in the present creation, all the members of the laser marking zone joining device 1 are not shown in Fig. 4, and only the elements related to the present embodiment are indicated. The laser marking device 11 has a user interface 111, a computing module 112, a controller module 113, and a galvanometer module 114. The user interface 111 is used for the user to draw graphics and import request data. In one embodiment, the user interface 111 is composed of a touch screen and a software graphics interface (GUI), and the user can directly draw the marking track that is desired to be implemented on the user interface 111 to form a graphic. Alternatively, the graphics are pre-printed on other terminal devices, and then input to the laser marking device 11 via the user interface 111 in the form of a file. In addition, the import request data refers to parameters that are used by the user when marking some partitions, and are input to the laser marking device 11 through the user interface 111, such as the laser energy size or the marking time. The computing module 112 outputs the readable data according to the graphics and the import request data. The readable data in the readable data refers to the readable data format of the controller module 113. .

Referring to FIG. 4, the computing module 112 has a path planning module 1121 and an energy computing module 1122. The path planning module 1121 is used to plan multiple marking nodes when the laser source device 13 performs zone marking (FIG. 4). A plurality of coordinates, not shown, each of which corresponds to a coordinate. For example, when the graphic is a circle, the path planning module 1121 will disassemble the circle into 20 nodes, and the distance between the node and the node is at least 1 mm, and the center of the circle is taken as the origin, according to the XY coordinate system. , all 20 nodes are given a specific coordinate value, and the 20 nodes are respectively defined, for example, the first node is A ₁ (1, 0), and the second node is A ₂ (2, 0) ), and so on to the 20th node is A ₂₀ (20,0) for the laser source device 13 to align when performing zone marking, the coordinate value is a graphic coordinate system, the coordinate system is a card type The XY coordinate system of the coordinate system is defined, and the origin is at the centroid of the graphic; the energy operation module 1122 is used to arrange the energy value array of the marking node 14A, and package and coordinate the coordinate and the energy value array of the marking node 14A. That is, the readable data that is converted into the controller module 113 is formed, and the readable data is transmitted to the controller module 113. In the embodiment of the present invention, the readable data may be a numerical control code, that is, The NC code, the so-called numerical control code, is the various control data that the user needs, such as: The spindle speed, the machining conditions, and the size of the workpiece are created into a series of numerical commands that are input into the controller to form a computer-readable information machine (CNC machine) to control the operation of the machine. The array of energy values of the marking node 14A may be a 5*5 matrix. In this array, each element is arranged in the order of the path planning module 1121, from left to right and from top to bottom. Each element represents a laser energy value that represents the laser energy required for that particular node.

Referring to FIG. 4 , the controller module 113 of the laser marking device 11 further includes an interpolation calculation module 1131 and a command output module 1132 . The controller module 113 receives the readable data transmitted by the energy calculation module 1122 and the galvanometer data transmitted by the galvanometer module 114, and then transmits the readable data and the galvanometer module 114 by using the interpolation calculation module 1131. After the galvanometer data is subjected to the interpolation operation, the preset value of the connection parameter is obtained, and then the command output module 1132 is used to transmit the preset value of the connection parameter to the laser source device 13. After receiving the preset value of the connection parameter, the laser source device 13 emits laser light according to the preset value of the connection parameter, and performs zone marking on the workpiece 14. It should be noted that the preset value of the connection parameter is formed by referring to the data set by the original user and the galvanometer module 114 and the galvanometer data of the laser source device 13, thereby improving the accuracy of the partition marking.

The galvanometer module 114 in the laser marking device 11 is used to drive the laser source device 13. The galvanometer module 114 has the same structure as the conventional laser marking machine, and has a galvanometer motor (not shown). And galvanometer Lens (not shown). The galvanometer module 114 still has some initial values (preset value/default) when the partitioning is not performed, such as the original position of the galvanometer motor and the galvanometer lens; there will be processing after the marking or after marking The process value, such as the different positions of the galvanometer motor and the galvanometer lens at different times during the marking, these initial values and processing values constitute the so-called galvanometer data. When marking different times, adding galvanometer data can dynamically adjust the marking, so that the marking point can better meet the needs of users.

Next, please refer to FIG. 5. FIG. 5 is a schematic diagram showing another embodiment of the laser marking partition bonding apparatus 1 provided by the present invention when performing partition marking. Similarly, in FIG. 5, only some of the components in the laser marking device 11 are displayed. In this embodiment, the visual device 12 includes an image capturing module 121 and an image matching module 122, which are transmitted through the visual device 12. The image capturing module 121 captures the partition marking image formed by the laser source device 13 after marking on the workpiece 14, and compares the image matching module 122 with the image matching module 122 to transmit the image discrimination result to the user. The interface 111, wherein the time of capturing the image of the partition formed by the laser source device 13 on the workpiece 14 of the visual device 12 may be an instant capture of the partition marking image when the marking of the first partition is performed, or After the marking in the first partition is completed, the partition marking image is captured, and the time for capturing the marking image of the partition is not within the scope of the limitation of the creation, and the partition marking image can be performed as long as the partition marking is performed. Capture. In this embodiment, the image capturing module 121 may be an image sensor, such as a CCD array, an MMOS array, or a photodiode array, such as a machine or device capable of capturing images. In addition, the partition marking image may be a graphic file, for example, a graphic file whose auxiliary file name is jpg, tif, png, bmp.

Referring to FIG. 5, the image comparison module 122 further includes an image processing module 1221, an identification module 1222, and a comparison module 1223. The comparison module 1223 further includes a database 1223A. The image processing module 1221 of FIG. 5 processes the partition marking image into a readable data format readable by the recognition module 1222, which is called identifiable data. For example, the image processing module 1221 converts the auxiliary file name into a jpg graphic. Archive (*.jpg), converted into a set of binary digital arrays with coordinates, The image processing module 1221 compares the converted identifiable data to the identification module 1222, and the identification module 1222 determines the determination area in the identifiable data, and This determination area is transmitted to the comparison module 1223 for comparison. As described in the prior art, the match head pattern in the marking image and the portion to be joined almost appear at the edge of the marked image, occupying only a part of the marked image, so in the present creation, through the recognition mode The determining means of the group 1222 extracts the identifiable data (the content of the partitioned marking image is still changed only in the data format of the partition marking image), and the judgment area that needs subsequent processing is extracted to effectively utilize the laser The zone partitions the resources in the device 1 and saves time for laser marking. After the identification module 1222 transmits the determination area to the comparison module 1223, the comparison module 1223 compares the determination area with the predetermined image in the database 1223A in the comparison module 1223. The comparison method is that the database 1223A determines the relevant data in a certain coordinate in the area, for example, the call point radius is called first, and then calls the relevant information of the specific coordinate on the predetermined image, for example, Marking point coordinates, the radius of the marking point in the judgment area under the same coordinate is subtracted from the radius of the marking point on the predetermined image. If the value after subtraction is greater than or equal to 1, it indicates that the judgment area is equal to the predetermined image, then the output is If the value after subtraction is less than 1, it means that the judgment area is smaller than the predetermined image, and the distortion is output. Here, the predetermined image is a standard image. The general user will pre-store the standard image of the graphic to be provided in the database 1223A through the laser marking partition bonding device 1 to provide the comparison module 1223. It is determined whether the determination area matches the predetermined image. This database 1223A can be a memory for storing a plurality of predetermined images.

Referring to FIG. 5, the comparison module 1223 compares the related data of each coordinate in the determination area with the related data of the predetermined image one by one, and then the visual device 12 returns the image determination result to the user interface 111. After the user interface 111 receives the image discrimination result, a warning message is sent to remind the user to determine the result. The warning message includes a normal prompt, a leak prompt, and a match head prompt. In this embodiment, if the image discrimination result has an anastomosis of 50 or more The warning message is a normal prompt; if the image discrimination result is not more than 50, the warning message is a match head prompt; if the image discrimination result has any one distortion, the warning message is a leak. Note, but the number of image discrimination results is not limited to 50, and the threshold can be set. When the user receives the warning message, the content of the request data will be adjusted according to the content of the warning message; when the normal prompt is not received, the user will repeat the adjustment request data until the normal prompt is obtained; when the user receives the normal When prompted, an automatic prompt is entered in the request data, at which point the laser marking zone engagement device 1 automatically begins to operate to transfer all of the graphics to the workpiece 14.

The laser marking partitioning device 1 proposed by the present invention can not only correct the partition marking image through repeated partition marking, but also determine the quality of the partition marking image by the computer through the visual device 12, thereby greatly reducing the artificial discrimination. The error is corrected in consideration of the data of the galvanometer module 114, and the interpolation operation is performed at the same time to take into account the preset value and avoid the connection error. More importantly, the device can immediately feedback the determination result of the zone marking image, and the user can adjust the input request data according to the warning signal to adjust the marking target of the marking zone without waiting for the entire marking image to be completed. It can be adjusted in real time, so it has deep industrial utilization.

Subsequent creations provide a laser marking partition bonding method. Please refer to FIG. 4, FIG. 5 and FIG. 6A to FIG. 6D. FIG. 6A to FIG. 6D are schematic diagrams showing the marking node when the laser marking partition bonding method provided by the present invention is performed. 6A is a partition of the graphic input by the user to the user interface 111, that is, the first partition prediction marking pattern 100, and FIG. 6B is a coordinate diagram of the plurality of marking nodes 14A planned by the path planning module 1121. FIG. 6C is a coordinate diagram of a plurality of marking nodes 14A after interpolation calculation by the interpolation calculation module 1131, and FIG. 6D is a partition marking image captured by the image capturing module 121. First, the path planning module 1121 plans a partition of the graphic input by the user for the user interface 111, such as the first partition, to generate a plurality of marking nodes 14A. Each of the marking nodes 14A generated at this time is equidistant from each other, and the distance is t, and generally t is 3 mm. The purpose of the equidistant distance is to enable the laser source device 13 to perform the constant velocity movement during the marking movement, The plurality of nodes generated in the path planning module 1121 are in the equal speed segment 14M, and the path planning module 1121 determines the isokinetic segment starting point 14C and the constant velocity segment ending point 14D in the velocity segments 14M to facilitate subsequent connection. Figure used. After the marking nodes 14A are arranged by the energy computing module 1122, each of the marking nodes 14A has an energy value to indicate that the laser source device 13 needs to generate an output power of a specific energy value at a specific marking node 14A. . After the interpolation calculation module 1131 in the subsequent controller module 113 receives the relevant data of each of the marking nodes 14A having the energy value, according to the current coordinate value of the galvanometer module 114 and the equal velocity segment 14M where the plurality of nodes are located. The starting point and the end point are interpolated. The so-called interpolation operation refers to inserting a value that is not included in the data generated by the path planning module 1121. The interpolation calculation module 1131 first captures the current coordinate value of the galvanometer module 114, and then inserts a plurality of mobile nodes 14B after the current coordinate value of the galvanometer module and the start point 14C of the constant velocity segment and the end point 14D of the constant velocity segment. The laser source device 13 and the galvanometer module 114 are aligned. At this time, each of the moving nodes 14B is not equidistant, because the galvanometer module 114 accelerates from the stationary state to the equal speed segment 14M, that is, when the acceleration segment 14S is accelerated, and the galvanometer module 114 is decelerated to a standstill. At the time of the deceleration section 14E, acceleration also occurs, so in the acceleration section 14S and the deceleration section 14E, the adjacent two moving nodes 14B are not equidistant. In a specific implementation of the present invention, the galvanometer module 114 performs an equal acceleration motion in the acceleration section 14S and the deceleration section 14E. Further, the galvanometer module 114 performs ² km/s ² in the acceleration section 14S.
