Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The traditional height calibration leveling compensation mode has the problems of low calibration compensation precision, mostly once calibration of a plane, single calibration compensation mode and the like, and cannot meet the requirement of the current high-precision 3D printing process on the flatness of a processing plane.
The invention mainly aims to provide a technical scheme capable of realizing printing of fine lines with the precision of 1 mu m on the surface of any substrate aiming at the defects of the prior art, in particular to substrates with overall uneven breadth, substrates with internal warping problem and substrates with poor internal surface roughness.
Fig. 1 is a flowchart of a method for compensating for the surface height calibration of a printing substrate according to the present invention, and referring to fig. 1, the method for compensating for the surface height calibration of a printing substrate according to the present invention comprises:
step 110: clamping a substrate, and adjusting the height of the substrate to enable the substrate to be within the measuring range of the sensor;
in the embodiment of the present invention, it should be noted that the height of the substrate may be adjusted manually, or may be adjusted by running an automatic height finding program.
Step 120: moving the printing nozzle and/or the substrate to a printing start point, starting printing and executing a height calibration compensation procedure during printing based on the measurement data of the sensor to keep the printing nozzle at a predetermined distance from the surface of the substrate until the printing process is completed.
To further illustrate the method for compensating the surface height calibration of the printing substrate provided by the present invention, referring to fig. 2, fig. 2 is a flowchart of a method for compensating the surface height calibration of the printing substrate according to an embodiment of the present invention, in this embodiment, a real-time scanning compensation method is provided, and the method includes:
step 1: clamping the substrate;
step 2: the substrate is moved to a proper height range, namely a sensor measuring range, in a manual adjusting mode or an automatic height searching program which is independently developed;
and step 3: moving the substrate to a printing start point;
and 4, step 4: starting a scanning compensation program and simultaneously running a printing program to start printing;
and 5: the printing is completed.
The scheme has high efficiency, the processing precision can also be stable and is 1 mu m, but the difficulty of the process implementation mode is higher, the focus of the sensor and the tip of the nozzle are ensured to be focused at the same point as far as possible, the distance between the focus of the sensor and the tip of the nozzle possibly exists in the actual situation, but the distance is controlled within a reasonable difference value obtained by converting the printing speed and the response speed of a compensation program, if the distance exists between the focus of the sensor and the tip of the nozzle, the positions of the sensor and the nozzle need to be changed in real time in the processing process of complex graphs, and the sensor is ensured to be always arranged at the front end of the spray head.
To further illustrate the method for compensating the surface height calibration of the printing substrate provided by the present invention, referring to fig. 3, fig. 3 is a flowchart of a method for compensating the surface height calibration of the printing substrate according to another embodiment of the present invention, in this embodiment, the performing the height calibration compensation procedure during the printing process based on the measurement data of the sensor includes: before the printing nozzle and/or the substrate is moved to the printing starting point, the relative positions of the needle head, the sensor and the camera are calibrated according to the preset marking point positions through the independently developed high-precision visual positioning and sensor independent positioning programs. After the calibration is finished, the needle head is moved to the printing processing starting point, scanning parameters are set, a scanning program is operated, and the sensor scans the surface of the substrate according to a set area, a set mode and corresponding parameters to obtain the scanning data of the surface of the printed substrate; after the scanning is finished, the printing needle head automatically returns to the preset printing starting point position; meanwhile, the processor processes the printing substrate surface scanning data in the background and executes a height calibration compensation program in the printing process based on the processing result. The scanning the surface of the substrate with the sensor comprises: scanning the entire region to be printed of the surface of the substrate with a predetermined accuracy; and/or scanning the surface of the substrate along the print path of the print nozzle with a predetermined accuracy. Specifically, a pre-scan compensation method is provided, the method comprising:
step 1: clamping a substrate;
step 2: the substrate is moved to a proper height range, namely a sensor measuring range, in a manual adjusting mode or an automatic height searching program which is independently developed;
and step 3: calibrating the relative positions of the needle head, the sensor and the camera according to preset marking point positions through independently researched and developed high-precision visual positioning and sensor independent positioning programs;
and 4, step 4: moving the substrate to a printing start point;
and 5: selecting a surface scanning mode or a printing path scanning mode and setting corresponding scanning parameters;
step 6: collecting data;
and 7: carrying out background data processing;
and 8: starting printing;
and step 9: the printing is completed.
In the embodiment of the invention, the most efficient 3D printing fine line processing can be realized by selecting different height calibration compensation modes according to different substrates.
In the case where the substrate surface roughness is poor and the machining accuracy requirement is particularly high, it may be selected to scan the surface of the substrate along the print path of the print nozzle with a predetermined accuracy. Fig. 4 is a schematic diagram of scanning the surface of the substrate using a sensor according to an embodiment of the present invention, and referring to fig. 4, in an embodiment of the present invention, the sensor is used to scan the surface of the substrate along the printing path of the printing nozzle with a predetermined precision, so as to obtain data of the distance between the printing nozzle and the surface of the substrate on the whole printing path, and according to the data, the height adjustment required to be performed by the printing nozzle in the printing process can be predetermined, the printing nozzle is accurately adjusted to be high at a position where the height adjustment is required, and the printing nozzle is adjusted to be low at a position where the height adjustment is required, so that the printing nozzle keeps a predetermined distance from the surface of the substrate, the integrity and accuracy of the printing line are ensured, and the printing nozzle is prevented from being damaged. The scheme is a processing path scanning compensation scheme, and is suitable for the conditions of poor surface condition and extremely high processing precision requirement. The processing of almost all cases can be satisfied, and to the sample that the processing route is simple relatively, machining efficiency is high, but to the sample that the processing route is long and complicated, machining efficiency is relatively low.
Wherein for the case of a relatively good substrate surface topography, the entire region of the surface of the substrate to be printed can be selected to be scanned with a predetermined accuracy. Fig. 5 is a schematic view of scanning a surface of a substrate using a sensor according to another embodiment of the present invention, and referring to fig. 5, in an embodiment of the present invention, scanning an entire to-be-printed area of the surface of the substrate with a predetermined accuracy, wherein scanning the entire to-be-printed area of the surface of the substrate with the predetermined accuracy includes: scanning unit areas covering the entire area to be printed with a predetermined scanning step, respectively, thereby scanning the entire area to be printed. As can be seen from fig. 5, each scanning point is spaced apart by a fixed scanning step, which is determined in advance based on the accuracy of the printed line, the time required to scan the entire substrate surface, the roughness of the substrate surface, and the like. And the four scanning points form a unit area, and all the unit areas are sequentially scanned until the whole area to be printed is scanned. The scheme is a small-area plane scanning compensation scheme (four scanning points form a small-area unit, and the relative level of the area is adjusted by using height data of the four points), and is suitable for the condition that the surface appearance of the substrate is relatively good. This scheme machining efficiency is high, also can reach higher printing precision.
