The above general description is made on the leveling control method of the 3D printer, and a detailed description is made below on the leveling control method of the 3D printer.
Referring to fig. 2, another embodiment of a leveling control method for a 3D printer in the embodiment of the present application includes:
201. acquiring image data of the target printing platform and carrying out image recognition to acquire a first characteristic identifier or acquiring an identification code associated with the target printing platform to acquire the first characteristic identifier;
the utility model provides a target print platform is photocuring 3D printer, before printing, in order to ensure the printing effect of printer, needs earlier to carry out leveling work.
Specifically, the system locks a printer which needs to execute printing work as a target printer, scans an identification code on a target printing platform of the target printer through a camera or identifies through NFC, collects image data of the target printing platform, and performs image identification to obtain a first feature identifier or obtain an identification code associated with the target printing platform to obtain the first feature identifier, where the identification code includes but is not limited to pattern identification information and a chip in which the identification information is stored, and the first feature identifier may be a sequence number, a color, a specific pattern, and the like. For example, if the first feature identifier of the target printing platform is a specific color, a sticker, a picture, or the whole platform with the specific color on the target printing platform may be scanned by the camera, image recognition may be performed according to an image scanned by the camera, a color value may be confirmed, and the first feature identifier corresponding to the target printing platform may be confirmed according to the color value; for another example, if the first feature identifier of the target printing platform is a chip in which identification information is stored, the chip is attached to the target printing platform, the identification information stored in the chip is acquired through the approach of the NFC smart device, and the first feature identifier corresponding to the target printing platform is confirmed.

It should be further noted that the identification method may be not only two-dimensional code scanning by a camera or NFC identification, but also others, and the specific application is not limited.
202. Acquiring at least one group of stored leveling data, wherein the leveling data comprises a second characteristic identifier of the printing platform and a leveling parameter corresponding to the second characteristic identifier;
in the embodiment of the present application, in order to determine whether the printing platform of the target printer has been leveled before, and to avoid repeated leveling, after the system determines the first feature identifier of the target printing platform, the system first reads at least one set of leveling data stored in the memory, where the leveling data includes the second feature identifier of the printing platform.
It should be noted that the first characteristic identifier may include one or more of a serial number, a printer attribute parameter, and an identification code; the second characteristic identification can also comprise one or more of a serial number, a printer attribute parameter and an identification code; the leveling data can also comprise one or more data of leveling time and printing times of the printing platform and leveling parameters of each feature point after the leveling of the printing platform is finished, wherein the leveling time refers to the time recorded after the previous leveling is finished, the printing times record all the printing times in the period from the previous leveling to the present, the feature point is a position point which is set in advance and used for collecting the current height data or the three-dimensional coordinate information on the printing platform, and the feature point collected after the leveling of each printing platform can support 16 feature points at most. The system stores the serial number, the leveling time, the printing times of the printing platform, leveling parameters collected by each characteristic point after the printing platform is leveled and the like for next calling.
When the light source is used, the light-curing 3D printer is used, for example, the plane where the printing platform is located is parallel to the plane of the bottom of the resin tank. Because the data are recorded after the leveling is successful, the corresponding position points of the printing platform can be quickly adjusted to the information corresponding to the characteristic points directly according to the information of different characteristic points in the subsequent leveling process of the printing platform, and the subsequent leveling of the printing platform is facilitated.
203. Judging whether the first feature identifier is consistent with the second feature identifier, if so, executing step 205; if not, go to step 204;

TABLE 1
It should be noted that, the platform serial number used in the present application ranges from 1 to 255, and the stored leveling platform data has 255 groups at most, and 16 feature points at most are used.
In table 1, assuming that one platform is leveled each time, leveling parameters are stored in sequence from small to large according to serial numbers, and the leveling of the printing platform at the first leveling is connected to the back. For example, the first leveled platform is marked with serial number 1, and the latest leveled platform is marked with serial number n. A set of leveling data is stored under each serial number, and the leveling parameters include, but are not limited to, the leveling time of the printing platform, the number of prints, and the leveling parameters of the printing platform. The system classifies, stores and manages the leveling data of the multiple groups of leveling platforms in a table form.
When printing is needed, in order to determine whether the target printing platform is a newly replaced platform, a latest set of leveling parameters stored in the database needs to be called for judgment at this time, that is, a set of data of the serial number n is called, if the feature identifier (such as sn code) of the set of data of the serial number n is consistent with the first feature identifier of the target printing platform, it indicates that the target printing platform has been leveled before and has not been detached all the time, and the step 205 is directly executed without initial leveling; if they are not the same, it indicates that the target printing platform may be a new platform, which has not been leveled before, or may have been leveled before, but has been replaced, and is replaced again, at this time, in order to determine which situation is, the system will compare the first feature identifier of the target printing platform with the remaining group of data stored in the table one by one according to the latest data to the earliest data stored, that is, compare the first feature identifier with the feature identifier stored in the serial number n-1, and then compare the first feature identifier with the feature identifier stored in the serial number n-2, if any group of the remaining groups is consistent with the first feature identifier, it indicates that the target printing platform has been leveled before, at this time, initial leveling is not needed, and step 205 can be directly executed; if all the comparison is finished and no consistency is found, the target printing platform is a new platform, at this time, initial leveling needs to be performed, and step 204 is specifically executed.
It should be noted that the embodiment of the present application is only an example, and the storage manner and the calling manner of the data in reality are not only the above-mentioned one.
It should be further noted that, a specific flowchart regarding determining whether the first characteristic mark and the second characteristic mark are consistent is shown in fig. 3.
In fig. 3, the process of determining whether the first feature identifier and the second feature identifier are consistent is: first, second leveling data is obtained from leveling data stored in history, and a corresponding second feature identifier is confirmed according to the leveling data, the system compares the second feature identifier with the first feature identifier to confirm whether the second feature identifier is consistent with the first feature identifier, if so, the target printing platform and the current printing platform are the same and are not detached and replaced, and step 309 can be directly executed; if the data of the target printing platform is inconsistent, it indicates that the target printing platform may be a new printing platform which has not been leveled, or a printing platform which has been used but has been detached and placed again, in order to determine whether the target printing platform has been leveled, at this time, it is necessary to continue to compare the first feature identifier of the target printing platform with the second feature identifiers of at least one group of leveling data remaining in the history storage, if a second feature identifier which is consistent with the first feature identifier exists in the remaining group, it indicates that the target printing platform has been leveled, at this time, step 307 and step 308 are executed, that is, a leveling parameter of the second feature identifier which is consistent with the first feature identifier is read, each feature point of the target printing platform is quickly leveled according to height data, position points of three-dimensional coordinate information and the like recorded in the leveling parameter, and after leveling is completed, the serial number of the target printing platform in the database needs to be updated, for example, the database is added with the total data 100 of the target printing platform, and the serial number of the target printing platform is 1, at this time, the serial number of the new printing platform should be updated in a sorting manner according to the above table, and the serial number should be 100; if the leveling data of all the groups are compared and the second feature identifier consistent with the first feature identifier does not exist, the target printing platform is indicated to be a new printing platform which is not leveled, at this time, step 306 is executed, namely, the target printing platform is initially leveled, the leveling parameters after the initial leveling are stored in a data table, and the serial number of the leveling parameters is marked as 100.
204. And carrying out initial leveling on the target printing platform, and storing leveling parameters after the initial leveling, wherein the leveling parameters comprise height parameters.
In the embodiment of the application, if the system does not find the second feature identifier corresponding to the first feature identifier of the target printing platform stored in the memory in a historical manner, the system executes an initialization leveling function, performs initial leveling on the target printing piece, and records leveling parameter data after leveling is completed, wherein the leveling parameter data includes, but is not limited to, current height data and position points of three-dimensional coordinate information.
It should be noted that, after the leveling is completed, the system records the leveling parameters, so as to avoid the operation of taking time to process leveling before each printing, and at the same time, in order to implement aging management, the current time node is also recorded, and the number of printing times is also recorded during each printing, so that when the target printing time or the target number of printing times exceeds the limit value, the system can perform leveling again, and the printing effect is maintained.
Specifically, after leveling is completed, the system collects current leveling data and stores the current leveling data in the memory, wherein the leveling data includes but is not limited to a feature identifier of the printing platform, the printing times of the printing platform, leveling time, height parameters collected by each feature point after the printing platform is leveled, and the like, so that the adjusted data can be directly used without repeated leveling in the next printing.
Regarding the initial leveling of the printing platform, it should be noted that, in some embodiments, the 3D printer has an automatic leveling function, and the sensor detects the height condition or the information of the three-dimensional coordinates of a plurality of position points in the printing platform correspondingly, and continuously adjusts the direction of the plane where the printing platform is located, so that the plane and the corresponding component are parallel to each other, so as to perform the initial leveling of the printing platform, and form initial leveling data.
For example, in some 3D printers with an auto-leveling function, the bottom surface of the printing platform is rectangular, and height sensors, such as infrared sensors or distance sensors, corresponding to four corners of the rectangular printing platform are distributed on the bottom plane of the resin tank attached to the printing platform. It is now necessary to level the rectangular bottom surface of the printing platform so that it is parallel to the plane of the bottom of the resin bath. The height detection is carried out through the sensors, the orientation of the rectangular bottom surface is continuously adjusted through the corresponding transmission mechanism, namely the direction of the rectangular bottom surface is continuously adjusted, so that the heights detected by the height sensors at four corners are basically the same, the rectangular bottom surface is kept parallel to the bottom plane of the resin tank, and finally the printing platform is locked through the locking mechanism, so that the rectangular bottom surface of the printing platform is kept parallel to the bottom plane of the resin tank within a period of time. At this point, initial leveling data is formed, and the system correspondingly acquires current leveling data, such as a feature identifier of the printing platform, the printing times of the printing platform, leveling time, height parameters acquired by a plurality of feature points after the printing platform is leveled, and the like, and stores the current leveling data in the memory to complete data recording. In some embodiments, the initial leveling of each printing platform may also be performed in a similar manner as described above, but due to factors such as whether the printing platform is flat or not and errors of the sensors, the machine does not know the final detection value corresponding to each sensor when the leveling is successful at the initial leveling, and the final detection value of each sensor is different, which is slower than the leveling performed by knowing the final detection value. The corresponding final leveling data is not known until after the initial leveling to form the leveling data in memory.
205. Judging whether the target printing platform is aged or not, if so, executing a step 207;
it should be noted that, after the system determines that the leveling is performed before the target printing platform is determined, in order to ensure that the leveling effect is still qualified, that is, whether the aging degree is lower than the limit value, the system may first obtain one or more parameters of the printing time, the printing times, the number of printing layers, and the printing volume in the leveling data of the target printing platform to analyze the aging degree, specifically, the printing time limit, the printing times limit, the number of printing layers limit, and the printing volume limit may be set in advance correspondingly, and by determining whether the printing time of the target printing platform exceeds the preset time, or determining whether the number of printing layers of the target printing platform exceeds the preset number of printing layers, or determining whether the printing volume of the target printing platform exceeds the preset volume, as long as one of the determinations exceeds the preset volume, it is determined that the target printing platform is aged.
In the embodiment of the application, if the aging degree is determined to be lower than the preset degree value, the current printing effect is good, and the printing work can be directly carried out according to the printing platform which is leveled last time.
206. And sending out a prompt or carrying out automatic leveling and recording corresponding leveling data.
It should be noted that, in this embodiment of the application, if it is determined that the aging degree is greater than or equal to the preset degree value, a prompt may be sent to prompt a worker to level the target printing platform, or automatically level the target printing platform, specifically, the height of each feature point of the target printing platform may be adjusted according to the leveling parameter corresponding to the second feature identifier of the target printing platform stored historically, or the initial leveling may also be performed, where a specific initial leveling method is consistent with step 204 in the embodiment of fig. 2, and this step is not described again.
It should be noted that, in the embodiment of the present application, in order to implement aging management, the system may record the current time node immediately after leveling is completed, and also record the number of printing times during each printing, so that when the target printing time or the target number of printing times exceeds a limit value, the system re-levels and maintains the printing effect.
Specifically, after leveling is completed, the system collects current leveling data and stores the current leveling data in the memory, wherein the leveling data comprises: the feature identification of the printing platform, the printing times of the printing platform, the printing time, the height data collected by each feature point after the printing platform is leveled and the like, so that the adjusted data can be directly used without repeated leveling in the next printing.
It should be further noted that, in the embodiment of the present application, since the memory stores the data after the last leveling, after the system re-levels, the new leveling data is updated to replace the data of the last leveling, or the data successfully leveled last time is directly used to help the printing platform to quickly level.
