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, not all, embodiments of the present invention. Without conflict, the embodiments and features of the embodiments described below may be combined with each other. 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 use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.
Referring to fig. 1, an embodiment of the present application provides a method for adjusting a nozzle pitch, which is applied to a printing apparatus, where the printing apparatus includes a first print head and a second print head, and the method for adjusting the nozzle pitch includes:
In actual operation, the model file may be stored in the printing apparatus in advance, or may be stored in a removable storage device such as a universal serial bus (usb) or a computer electrically connected to the printing apparatus. And the printing equipment controls the first printing head and the second printing head to print the printing models corresponding to the model files according to the model files.
Wherein the print model is to indicate offset information of the second printhead relative to the first printhead. In particular, the print model may include offset information that a user may view to determine.
Offset information, i.e., the offset distance of the second printhead relative to the first printhead. If the printing apparatus wants to eject the printing consumables at the same position, for example, position a, when the first printhead and the second printhead are printing, both the first printhead and the second printhead should eject the printing consumables at position a. If the first printing head or the second printing head is deviated, the ejecting position of at least one printing head is deviated.
The offset information may be 0.1mm if the second printhead is offset by 0.1mm in a positive direction of the first direction relative to the first printhead, and the offset information may be-0.1 mm if the second printhead is offset by 0.1mm in a negative direction of the first direction relative to the first printhead. It can be understood that the positive and negative of the offset information can be set according to the need or by self-definition.
And 102, acquiring offset information obtained according to the printing model, wherein the offset information corresponds to the offset information of the second printing head relative to the first printing head.
In this step, the user inputs offset information determined by viewing the print model to the printing apparatus, and the printing apparatus acquires the offset information obtained from the print model in response to the input operation by the user.
Specifically, the offset information corresponds to offset information of the second printhead relative to the first printhead. In other words, in this embodiment, during the adjustment, the measurement is performed with the first print head as the reference print head and the second print head as the print head to be measured. This is by way of example only and not by way of limitation. It is to be understood that in the present application, it is not limited which is the first print head and which is the second print head. If the second printing head is used as a reference printing head, the first printing head is used as a printing head to be measured to measure. However, any modification thereof is within the scope of the embodiments of the present application.
And 103, adjusting the nozzle position information of the second printing head in the printing equipment according to the offset information so as to adjust the design distance between the first printing head and the second printing head in the printing equipment.
Specifically, the position of the nozzle of the second print head may be compensated, and if the second print head is shifted by 0.1mm in the positive direction of the first direction relative to the first print head, in the software setting, the position of the second print head may be shifted by 0.1mm in the negative direction of the first direction, and when the first print head and the second print head are reused to print a model, the positions of the model printed by the first print head and the second print head will not be shifted in the first direction.
According to the method for adjusting the distance between the two printing heads, the printing equipment can adjust the position information of the second printing head in the printing equipment according to the offset information so as to adjust the design distance between the first printing head and the second printing head in the printing equipment, and the models printed by the printing heads do not need to be measured by means of measuring tools.
Optionally, the offset information includes first direction deviation information and second direction deviation information;
adjusting the position information of the nozzle prestored in the printing equipment by the second printing head according to the offset information, wherein the adjusting comprises the following steps:
adjusting the position information of the second printing head in the first direction relative to the first printing head in the printing equipment according to the first direction deviation information;
and adjusting the position information of the second printing head in the second direction relative to the first printing head in the printing device according to the second direction deviation information.
The first direction and the second direction are not the same direction, and the specific directions of the first direction and the second direction are not limited. For example, the first direction may refer to an X-axis direction during printing, and the second direction may refer to a Y-axis direction during printing. That is, the first direction deviation information may refer to deviation information of the second print head in the X-axis direction, and the second direction deviation information may refer to deviation information of the second print head in the Y-axis direction. In this alternative embodiment, the printing apparatus may adjust the position information of the second print head in the X-axis direction based on the deviation information of the second print head in the X-axis direction, and the printing apparatus may also adjust the position information of the second print head in the Y-axis direction based on the deviation information of the second print head in the Y-axis direction. In this way, adjustment of the positional information of the second print head in the X-axis direction and the Y-axis direction can be achieved.
Alternatively, as shown in fig. 2, the printing model includes several model blocks 10 arranged in a first direction;
It is understood that the first print head prints the first model block 102, the second print head prints the second model block 103, and the first model block 102 and the second model block 103 correspond in position, that is, the first model block 102 and the second model block 103 of each model block 10 correspond in position, and a preset corresponding relationship is provided between the position of the first model block 102 and the position of the second model block 103. Specifically, the second model block 103 corresponds to a scale value, and the user can view the second model block 103 to determine the scale value corresponding to offset information indicating an offset of the second printhead relative to the first printhead. The scale value corresponding to the second model block 103 in the plurality of model blocks 10 arranged in the first direction is used for the user to determine the offset information of the second print head relative to the first print head in the first direction.
It is to be understood that the number of the plurality of the sensors may be one, or may be one, two, or more than two.
Optionally, the printing model further comprises several model blocks 10 arranged along the second direction. The model block 10 arranged in the second direction is used for the user to determine the offset information of the second print head relative to the first print head in the second direction.
Optionally, the printing model further comprises a base 101, and the first model block 102 and the second model block 103 are both provided on the base 101.
In this alternative embodiment, the manner in which the first model block 102 and the second model block 103 are disposed on the base 101 is not limited, such as the first model block 102 and the second model block 103 are disposed on the base 101, or the second model block 103, the first model block 102, and the base 101 are stacked. The base 101 has a certain thickness, the base 101 is used for providing a setting platform for the first model block 102 and the second model block 103, the specific thickness of the base 101 can be determined according to an actual application scenario, and the base 101 is not limited herein, and only needs to be capable of providing a setting platform for the first model block 102 and the second model block 103. The base 101 is used to better secure the first model block 102 and the second model block 103 to a printing platform of a printing apparatus when printing the first model block 102 and the second model block 103. The individual model blocks 10 also maintain their position as the user sweeps the print model off the printing platform, facilitating better use of the print model by the user and determining the offset information of the second print head relative to the first print head. It is understood that when the printing model does not include the base 101, the user may view the printing model directly on the printing platform.
Optionally, controlling the first print head and the second print head to print the print model corresponding to the model file according to the model file includes:
controlling a first print head to print a first model block 102 according to the model file;
the second print head is controlled to print the second model block 103.
In this alternative embodiment, the printing apparatus controls the first printhead to print the first model block 102; the second print head is controlled to print the second model block 103. In other words, in this embodiment, the first print head is the reference print head, and the second print head is the test print head. In this way, offset information of the second printhead relative to the first printhead can be determined.
Optionally, the distance between two adjacent first model blocks 102 is equal, and the distance between two adjacent second model blocks 103 is equal; the distance of two adjacent first model blocks 102 is different from the distance of two adjacent second model blocks 103;
the model block 10 at the intersection position of the first direction and the second direction is an origin model block, the scale value corresponding to the second model block 103 of the origin model block is 0, the scale values corresponding to different second model blocks 103 are different, and the printing apparatus sets the first model block 102 of the origin model block to coincide with the second model block 103 of the origin model block.
It is understood that the printing apparatus sets the first model block 102 of the origin model block to coincide with the second model of the origin model block, and if there is a deviation between the first and second printheads, the first model block 102 of the origin model block does not coincide with the second model block 103 of the origin model block.
Since the distance of two adjacent first model blocks 102 is equal, the distance of two adjacent second model blocks 103 is equal; if the distance between two adjacent first model blocks 102 is different from the distance between two adjacent second model blocks 103, similar to the principle of vernier caliper, only the first model block 102 and the second model block 103 of one model block 10 should be overlapped, and the offset information corresponding to that model block 10 can be determined by observing which model block 10 the first model block 102 and the second model block 103 are overlapped.
Optionally, the second model block 103 is stacked with the corresponding first model block 102, or the second model block 103 and the corresponding first model block 102 are located on the same plane.
As shown in fig. 3 to 8, in this alternative embodiment, the stacked arrangement may mean that the second model block 103 shown in fig. 3 is arranged on the base 101 through the first model block 102. It can be understood that if the first model block 102 and the second model block 103 belong to the same model block 10, the first model block 102 is the first model block 102 corresponding to the second model block 103. If the second model block 103 and the corresponding first model block 102 are located on the same plane, it can mean that the second model block 103 and the corresponding first model block 102 are located on the base 101 at the same time as shown in fig. 8. If the printing model does not include the base 101, the second model block 103 and the corresponding first model block 102 are located on the same plane, which may be the case when the second model block 103 and the corresponding first model block 102 are located on the printing platform of the printing apparatus at the same time.
Optionally, the second model block 103 comprises a second sub-model block; the second sub-model block is in a cube shape, the cross section of the second sub-model block is in a quadrilateral shape, a cross shape, a triangular shape or a circular shape, and the second sub-model block corresponds to a preset scale value; or the second sub-model block is linear and corresponds to a preset scale value.
In this alternative embodiment, in the first implementation, the shape of the second sub-model block may be a cube, and when the shape of the second sub-model block is a cube, the cross section of the second sub-model block may be a quadrangle, a cross, a triangle, a circle, or the like, which is only an example and is not limited herein. Note that the scale values corresponding to the second submodels of different model blocks 10 are different. Specifically, the preset edge of the second sub-model block may be set to correspond to a preset scale value, where the preset edge of the second sub-model block is an edge of the second sub-model block facing the user, in other words, the preset edge of the second sub-model block is an edge that can be visually checked when the user checks the second sub-model block, and for example, the preset edge may be an edge perpendicular to the first direction, like the plurality of model blocks 10 arranged in the first direction.
If the second sub-model blocks are linear, each second sub-model block corresponds to a scale value.
Therefore, the second sub-model module is set to be in different shapes, so that the shapes of the printing models can be more diversified, and more personalized requirements of users can be met.
Optionally, the second model block 103 further comprises a preset scale value, and the position of the preset scale value corresponds to the position of the second sub-model block.
Specifically, the second model block 103 further comprises a preset scale value, and the position of the preset scale value corresponds to the position of the second sub-model block, for example, the scale value may be disposed on the second sub-model block, or the scale value is located at a side of the second sub-model block, and in this case, the scale value may be disposed on the base 101 at a side of the second sub-model block.
The numerical value of the scale value is consistent with the corresponding scale value of the second sub-model block, and a user can directly observe the numerical value of the scale value without judging the numerical value corresponding to the second sub-model block. It can be understood that the scale value may not be set, and the user may autonomously determine the scale value corresponding to the second sub-model block according to the position of the origin model block. It can be understood that if the second model block 103 does not include the preset scale value, the user cannot view the scale value, and the scale corresponding to each model block 10 needs to be determined by the user according to the setting.
In the direction away from the origin model block, the corresponding scale value gradually increases or gradually decreases. Specifically, the scale value gradually increases in the direction away from the origin model block corresponding to the second sub-model block with the scale value being a positive number; and the scale value is gradually reduced in the direction far away from the original point model block corresponding to the second sub-model block with the scale value being negative.
The shape of the first sub-model block 102 is the same as the shape of the second sub-model block.
In this alternative embodiment, the shape of first model block 102 is set to be the same as the shape of the second sub-model block, for example, when the second sub-model block is a three-dimensional shape, first model block 102 is also a three-dimensional shape, and when the second sub-model block is a linear shape, first model block 102 is also a linear shape, so that the comparison between the position of second model block 103 and the position of first model block 102 can be better achieved.
Wherein the color of the first model block 102 and the color of the second model block 103 may be different. The color of the first model block 102 is set to be different from the color of the second model block 103. In this way, the first model block 102 and the second model block 103 can be more intuitively distinguished.
When the user uses the printing model, the manner of determining the offset of the second printing head in the first direction relative to the first printing head through the printing model may include:
in a first implementation, in a first direction, such as the x direction shown in fig. 1, an origin model block is first determined, and the origin model block may be preset. And setting the corresponding scale value 0 of the original point model block. If the spacing between two adjacent second model blocks 103 is 0.1 units greater than the spacing between two adjacent first model blocks 102, then the second model block 103 of the nth model block 10 to the left of the origin model block is displaced from the first model block 102 by n × 0.1 units. Specifically, taking the model block 10 corresponding to the scale value 0.2 from the origin model block to the left as an example, in the model block 10 corresponding to the scale value 0.2, it is assumed that under normal conditions, the model block 10 of the second model block 103 to be printed should be shifted to the left compared with the model block 10 in the first model block 102, and in the actually printed print model, if the second model block 103 corresponding to the scale value 0.2 is aligned with the corresponding first model block 102, it is described that the second print head is shifted by 0.2 unit to the right, and since the second print head is shifted by 0.2 unit to the right, the model block 10 in the second model block 103 in the print model is aligned with the model block 10 in the first model block 102, at this time, the user may determine that 0.2 is the shift information.
Alternatively, in the first direction, if the corresponding model block 10 with a scale value of-0.2 is aligned, then-0.2 can be determined to be an offset. Thus, by the alignment of the model blocks 10 in the printed model, the offset can be quickly determined, the manual measurement process is reduced, and the deviation size of the nozzle pitch can be obtained without a caliper or other measurement tools. The determining manner of the offset in the second direction is consistent with the determining manner of the offset in the first direction, and details are not repeated here.
In the second implementation, taking model block 10 corresponding to scale value 0.2 and model block 10 corresponding to scale value 0.3 as examples in the first direction, if model block 10 corresponding to scale value 0.2 is shifted in the positive direction of the first direction than model block 10 of first model block 102 in model block 10 corresponding to scale value 0.2, and model block 10 corresponding to scale value 0.3 is shifted in the negative direction of the first direction than model block 102 in model block 103 corresponding to scale value 0.3, the average value is taken as shift information 0.25. Under the same offset condition, the determining manner of the offset in the second direction is similar to the determining manner of the offset in the second direction, and details are not repeated here.
In the third implementation, in the model block 10 corresponding to the number 0.1, the model block 10 of the second model block 103 is shifted to the left compared to the model block 10 of the first model block 102, in the model block 10 corresponding to the number 0.2, the model block 10 of the second model block 103 is shifted to the left compared to the model block 10 of the first model block 102, and so on, in all model blocks 10, the model block 10 of the second model block 103 is shifted to the left compared to the model block 10 of the first model block 102, and at this time, the smallest scale value in all model blocks 10 is selected as the offset. Further, the printing device adjusts the second printing head according to the offset, and then reprints at least one preset file model to further confirm the more accurate offset. Under the same offset condition, the determination manner of the offset in the second direction is similar to that of the offset in the first direction, and details are not repeated here.
Thus, by using a plurality of model blocks 10, the offset of the second print head in the first direction or the second direction can be quickly determined, thereby reducing the manual measurement process and obtaining the deviation size of the nozzle pitch without a caliper or other measurement tools. And the manual operation machines are reduced, the automatic control system is suitable for people with weak operation capability, the manual operation workload is less in the batch production machines, and the automatic control system is more suitable for batch operation production.
