Detailed Description
In order to better understand the aspects of the present application, the present application will be described in further detail with reference to the accompanying drawings and detailed description. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a 3D printing model cleaning method according to an embodiment of the present application. The 3D printing model cleaning method is applied to a cleaning device and can comprise the following steps:
s11: and acquiring the model height and the model complexity of the 3D printing model to be cleaned.
It can be appreciated that the model height of the 3D printing model, i.e. the height in the vertical direction when the model is normally placed; the model complexity of the 3D printing model is related to the roughness of the model surface; in practical application, the model complexity can be set to a complexity level, and after the 3D printing model is designed and molded, the model complexity corresponding to the 3D printing model can be approximately determined according to the surface concave-convex structure of the 3D printing model.
In practical application, the appearance image of the 3D printing model can be obtained through the camera, so that the model height and the model complexity of the 3D printing model can be determined. Of course, the printing parameters may be directly input by the staff member according to the 3D printing model, and the present application is not particularly limited.
It will be appreciated that the height of the model may also be received by the user or may be identified by the sensor.
S12: and determining the spraying height of the cleaning liquid according to the model height, and determining the spraying speed of the cleaning liquid according to the model complexity.
Unlike the conventional method of immersing the 3D printing model in a cleaning solution and cleaning the 3D printing model by stirring the cleaning solution. The 3D printing model is cleaned by spraying cleaning liquid on the surface of the 3D printing model. Compared with a soaking and cleaning mode, in the process of spraying the cleaning liquid, the cleaning liquid can generate stronger impact force on the surface of the 3D printing model, so that the cleaning effect of the 3D printing model is improved.
On the basis, in order to further improve the accuracy of cleaning the 3D printing model, invalid spraying is reduced as far as possible, and the spraying height and the spraying speed of the cleaning liquid are set in a targeted manner further based on related parameter data such as the 3D printing model and the model complexity, so that the cleaning accuracy is improved and excessive energy consumption is avoided on the basis of ensuring the cleaning effect of the 3D printing model.
It will be appreciated that the spray height of the cleaning liquid depends on the height of the 3D printing model itself, whereby the model height can generally be directly equal to the spray height; of course, in practical application, small errors may exist in the height which can be actually achieved by spraying the cleaning liquid, so that the spraying height can be set to be slightly larger than the height of the model, and the surface of the whole 3D printing model can be completely cleaned. In practical applications, the parameter data such as the model height is obtained by manual input or transmitted to the cleaning device through a 3D printer system.
In addition, in the cleaning device for actually cleaning the 3D printing model, the spray height of the spray cleaning liquid may not be arbitrarily set, but a certain height range exists, and if the spray height exceeds the maximum height range in which the cleaning liquid can be actually sprayed, the cleaning process of the 3D printing model may not be performed.
To this end, in an alternative embodiment of the application, determining the spray height of the cleaning liquid from the model height may specifically comprise:
judging whether the height of the model is smaller than or equal to the maximum cleaning height;
if yes, determining the model height as the spraying height of the cleaning liquid;
If not, determining the maximum cleaning height as the spraying height of the cleaning liquid.
As before, the model height in the present application is obtained by manual input or uploading to the cleaning device by a 3D printer. The model height thus obtained may be erroneous, and subsequent cleaning will not be completed if the erroneous model height exceeds the maximum height at which spray cleaning is actually possible in the cleaning device. Therefore, in this embodiment, the model height of the 3D printing model is first approximately determined, if the model height is smaller than the maximum cleaning height, the model height may be directly used as the spraying height, and when the model height is actually higher than the maximum cleaning height, the parameter of the input model height is wrong, and the maximum cleaning height may be directly used as the spraying height, so that the 3D printing model may be completely cleaned on the basis that the subsequent cleaning procedure can be completed.
In addition, the complexity of the model in this embodiment may be complexity level data determined by the 3D printer according to the parameter data of the 3D printing model, or complexity level data determined manually based on the roughness of the surface of the 3D printing model, which is not particularly limited in this embodiment.
As described above, in the present embodiment, the 3D printing model is cleaned by spraying the cleaning liquid onto the surface of the 3D printing model. Accordingly, the spraying speed in this embodiment is the flow rate of the cleaning solution sprayed and output by the spray head or the spray orifice to the surface of the 3D printing model, or the volume of the cleaning solution sprayed in unit time.
Generally, the higher the model complexity of the 3D printing model is, the higher the spraying speed is, and the greater the impact cleaning force on the surface of the 3D printing model is, so that the effective cleaning of the 3D printing model is ensured to a certain extent.
S13: and spraying cleaning liquid to the 3D printing model according to the spraying speed and the spraying height for cleaning.
In the embodiment, the spray height determined by the model height limits a more accurate cleaning range of the 3D printing model, and the spray speed determined according to the model complexity of the 3D printing model ensures more accurate cleaning force of the 3D printing model; based on the spraying speed and the spraying height, the 3D printing model is cleaned, so that the cleaning accuracy and the good cleaning effect of the 3D printing model can be ensured to a great extent.
In summary, in the application, the spray height is determined according to the model height of the 3D printing model to be cleaned, and the spray speed is determined according to the model complexity; and based on the spray speed and the spray height, the 3D printing model to be cleaned is sprayed, so that the 3D printing model is subjected to adaptive spray cleaning according to the model condition of the 3D printing model, the 3D printing model is accurately cleaned, and the condition that the 3D printing model is not cleaned cleanly is avoided.
Based on the above discussion, the 3D printing model cleaning method of the present application will be further described in more detail by way of example, and specific embodiments will be described below.
In an optional embodiment of the present application, in the process of cleaning the 3D printing model, before spraying the cleaning solution to the 3D printing model according to the spraying speed and the spraying height for cleaning, the method may further include:
acquiring a cleaning duration parameter of the 3D printing model;
if the cleaning time length parameter is more than or equal to the minimum cleaning time length and less than or equal to the maximum cleaning time length, the cleaning time length parameter is taken as the cleaning time length;
if the cleaning time length parameter is smaller than the minimum cleaning time length, taking the minimum cleaning time length as the cleaning time length;
if the cleaning time length parameter is larger than the maximum cleaning time length, determining the maximum cleaning time length as the cleaning time length;
correspondingly, spray the washing liquid to 3D printing model according to spray speed and spray height and wash, include:
and spraying and cleaning the 3D printing model according to the spraying speed, the spraying height and the cleaning time.
The maximum cleaning time and the minimum cleaning time can be manually input by a user, can be preset, and can be stored in a memory of the cleaning device, wherein the memory can be a movable memory or a fixed memory.
It will be appreciated that in the process of cleaning the 3D printing model, it should be ensured that at least one cleaning pass is performed at each position on the surface of the 3D printing model, and if the 3D printing model has a relatively complex structure or has a relatively large surface attachment, it is considered to perform cleaning on the 3D printing model for a longer period of time. The minimum cleaning time in this embodiment is the time required for cleaning the 3D printing model once.
Further, it is further considered that, for a cleaning device that sprays cleaning liquid to clean a 3D printing model, such as running for a long time, it may cause machine heating, or be liable to cause equipment malfunction, or waste electric power, or the like. In this embodiment, the longest cleaning time length that the cleaning device can safely operate is taken as the maximum cleaning time length of the spray cleaning, and the cleaning time length of the 3D printing model is limited between the maximum cleaning time length and the minimum cleaning time length.
Moreover, similar to the parameters such as the model height, the cleaning duration parameter in this embodiment may be determined by manual input, or the cleaning duration parameter is selected by the cleaning device by default according to the model complexity, where the cleaning duration parameter may exceed the maximum cleaning duration and the minimum cleaning duration. Therefore, the method and the device can ensure that the finally determined cleaning time is within the range of the maximum cleaning time and the minimum cleaning time, and further avoid equipment failure caused by long-time operation of the cleaning device on the basis of ensuring that the 3D printing model is completely cleaned.
In addition, as described above, the minimum cleaning time period in the present embodiment is a cleaning time period required to ensure that the 3D printing model is completely cleaned once; it is apparent that the minimum cleaning time is determined based on factors such as the size of the 3D printing model and the complexity of the model. When the cleaning time length parameter is manually input, or when the cleaning device selects the default cleaning time length parameter according to the model complexity, the input cleaning time length may be too small, or even smaller than the minimum cleaning time length.
Therefore, in practical application, the input mode of the cleaning time length parameter may only select a multiple parameter, for example, 1 time may be selected and input, the cleaning time length parameter is equal to the minimum cleaning time length, and when 2 times is selected and output, the cleaning time length parameter is 2 times of the minimum cleaning time length, and so on, so that the input cleaning time length parameter is not less than the minimum cleaning time length. But obviously, the cleaning time length parameter may be larger than the maximum cleaning time length, so that comparison can be performed between the product of the input multiple parameter and the minimum cleaning time length and the maximum cleaning time length, and if the cleaning time length is larger than the maximum cleaning time length, the maximum cleaning time length is directly set to be the cleaning time length. Of course, when the cleaning time length parameter is actually input, the time length parameter may be set by the staff based on experience according to the model height, the model complexity, and the like, and the embodiment is not particularly limited.
In addition, the cleaning solution capable of cleaning the 3D printing model is generally various, and in order to ensure the cleaning effect of the 3D printing model, at least two cleaning solutions are often required to be selected to perform mixed cleaning on the 3D printing model. The mixed cleaning is to adopt at least two cleaning solutions, and each cleaning solution is used for completely cleaning the 3D printing model at least one time in turn. For this reason, from the viewpoint of the cleaning mode used, the minimum cleaning time period referred to in this embodiment also refers to the total time period required for all kinds of cleaning liquid to complete one complete cleaning of the 3D printing model alone.
Based on the above discussion, the 3D printing model is cleaned by spraying the cleaning solution in the application, and various cleaning methods exist in practical application. For example, the spray heads of the cleaning device are distributed in a cylindrical shape, and the spray direction of each spray head points to the central axis of the cylinder where each spray head is positioned; meanwhile, the 3D printing model is also arranged on the central axis of the cylinder where each spray head is located, so that each spray head can spray cleaning liquid from each direction to the surface of the 3D printing model to clean the 3D printing model. It is obvious that the cleaning mode also has certain requirements on the spray heads for spraying the cleaning liquid, each spray head should spray the cleaning liquid in a way of having a certain divergence angle, so that the spray water column is a conical water column, at least partial overlapping exists between the adjacent two spray heads in the surface spray coverage area of the 3D printing model, and the spray areas of all spray heads completely cover the whole surface of the 3D printing model.
For the above spray cleaning mode, the number of required spray heads is relatively large, and the cost of the cleaning device may be relatively large, but the cleaning speed is higher, so that the 3D printing model can be quickly cleaned in a shorter time. In addition, in order to adapt to the cylindrical radius sizes of different models, the spray heads can be adjusted, namely, the distance between each spray head and the 3D printing model is adjustable, so that the problem that the spray cannot completely clean the 3D printing model due to too close distance between the spray heads and the 3D printing model is avoided.
Further, as shown in fig. 2, in another embodiment of the present application, a smaller number of spray heads may be provided, but cleaning of the entire surface of the 3D printing model may be achieved by controlling the relative movement or rotation between the spray heads and the 3D printing model during spray cleaning of the 3D printing model. Thus, in an alternative embodiment of the present application, it may further comprise:
the spray head for spraying the cleaning liquid is connected with a first motor, and the first motor is used for driving the spray head to move along the height direction of the 3D printing model;
determining a spray height of the cleaning liquid according to the model height, comprising:
Determining the spraying height of the first motor-driven spray head according to the model height;
spraying cleaning liquid to the 3D printing model for cleaning according to the spraying speed and the spraying height, and comprises the following steps:
and controlling the first motor to drive the spray head to move along the height direction of the 3D printing model according to the spray height and the cleaning time, and controlling the spray head to spray the cleaning liquid at the spray speed.
In this embodiment, a circle of nozzles may be annularly arranged with the 3D printing model as the center, and the injection direction of each nozzle points to the central axis of the ring where the nozzle is located; correspondingly, a 3D printing model is also provided on the central axis. For example, the 3D printing model may be vertically and fixedly disposed on a carrying platform of the cleaning device, and the plane where each nozzle is located is a plane in a horizontal direction, and at this time, the spraying direction of each nozzle may spray the cleaning liquid to the 3D printing model vertically along the horizontal direction; of course, each spray head can spray cleaning liquid to the 3D printing model in an inclined upward direction or an inclined downward direction with a certain included angle with the horizontal direction.
The driving spray head moves along the height direction of the 3D printing model, can be the position where the driving spray head moves to the spraying height, and can also move back and forth in the spraying height and a certain section below the spraying height. It will be appreciated that the spray head is connected to a first motor, i.e. the spray head is in driving connection with the first motor, whereby the first motor can drive the spray head to move.
On the basis, each spray head is in driving connection with a first motor, the first motor can drive all spray heads to synchronously move up and down along the vertical direction, so that each different height position of the 3D printing model can be sprayed and cleaned, and the height range interval of the first motor moving along the height direction of the 3D printing model is equal to the determined spraying height. Therefore, in the process of cleaning the 3D printing model, each spray head can be started to spray cleaning liquid according to the preset spraying speed, and then the first motor is started to drive each spray head to move in the range of the spraying height along the vertical direction, so that the cleaning of the surface of the 3D printing model can be realized.
Based on the above discussion, in order to further enhance the cleaning effect, in another alternative embodiment of the present application, it may further include:
the 3D printing model is arranged on the bearing platform, and the bearing platform is connected with a second motor which is used for driving the 3D printing model to rotate;
after obtaining the model height and the model complexity of the 3D printing model to be cleaned, the method further comprises:
determining the rotating speed of the second motor for driving the 3D printing model to rotate according to the model complexity; wherein, the higher the model complexity, the smaller the rotation speed;
Spraying cleaning liquid to the 3D printing model for cleaning according to the spraying speed and the spraying height, and comprises the following steps:
dividing the cleaning surface of the 3D printing model into a plurality of working areas which are distributed in sequence along the height direction of the 3D printing model according to the spraying height;
and controlling the first motor to drive the spray heads to sequentially run to the spraying positions corresponding to each working area, controlling the second motor to drive the 3D printing model to rotate at a rotating speed, and controlling the spray heads to spray cleaning liquid to the 3D printing model at a spraying speed.
The cleaning device in this embodiment is configured with a first motor for driving the head to move in the vertical direction and a second motor for driving the 3D printing model to rotate along the central axis of the vertical direction. Therefore, the spray cleaning position points of the spray head on the surface of the 3D printing model can be changed in a moving way along with the driving work of the first motor and the second motor, and when each position of the surface of the 3D printing model is sprayed and cleaned, the 3D printing model is completely cleaned.
It can be understood that, for the number of the nozzles in this embodiment, only one nozzle may be provided, or a plurality of nozzles may be provided, when a plurality of nozzles are provided, each nozzle may be arranged in an annular layout in the same horizontal plane as shown in fig. 2, and the central axis of the ring where each nozzle is located coincides with the central axis of rotation of the 3D printing model, and each nozzle may be uniformly arranged; of course, in practical application, the spray heads may be arranged on the same straight line along the vertical direction, and the application is not limited in particular.
In order to ensure complete cleaning of different positions on the surface of the 3D printing model, in the process of driving the spray head to move in the vertical direction in real time, the 3D printing model is divided into a plurality of operation areas in the vertical direction according to the coverage area of the cleaning liquid sprayed by the spray head on the 3D printing model and the width of the cleaning liquid in the vertical direction under the condition that the spray head is kept still. In the actual cleaning process, after the first motor-driven spray nozzle is firstly positioned at a position where the spraying direction is opposite to the first operation area, the first motor is controlled to stop, the second motor-driven 3D printing model is started to rotate while the spray nozzle is controlled to start spraying cleaning liquid, when the first operation area of the 3D printing model is completely cleaned, the first motor-driven spray nozzle is started to move to a position where the spraying direction is opposite to the second operation area along the vertical direction, when the second operation area on the 3D printing model is also cleaned, the first motor-driven spray nozzle is moved to a position where the spraying direction is opposite to the third operation area, and so on until all operation areas are cleaned, the 3D printing model can be cleaned completely once.
Specifically, controlling the first motor to drive the spray heads to sequentially operate to the spraying positions corresponding to each working area may include:
Controlling a first motor to drive the spray head to run to a height position corresponding to the current operation area under the state that the spray head is kept to spray cleaning liquid;
controlling the first motor to stop driving the spray head to move;
when the spray head finishes spray cleaning of the current operation area on the 3D printing model, the first motor is driven and controlled to drive the spray head to run to the height position corresponding to the next operation area.
It can be understood that in the process of cleaning each working area by the spray heads, if only one spray head is arranged, or each spray head is linearly distributed along the vertical direction, the 3D printing model is required to rotate at least one circle, so that the whole cleaning of the working area can be ensured; and when the number of the spray heads is 2, the spray heads are rotated at least 180 degrees, and the 3D printing model is analogically rotated by the same way, and the number of the spray heads distributed in a ring shape is related to the angle of rotation.
In order to ensure complete cleaning of each working area, in the process that the spray head sprays cleaning liquid to each working area of the 3D printing model, whether the second motor drives the 3D printing model to finish setting a rotation angle or not can be judged in real time, and if so, the spray head is stated to finish spray cleaning of the current working area on the 3D printing model. The set rotation angle should be not smaller than the minimum rotation angle, that is, the central angle between two adjacent spray heads on the ring where each spray head is located in the set spray head. Of course, when only one spray head or a plurality of spray heads are arranged straight in the vertical direction, the minimum rotation angle is 180 degrees.
In addition, in the actual cleaning process, it may be set that each operation area needs to be completely cleaned for 2 times, 3 times or more to complete cleaning, and the present application is not particularly limited thereto. And in the whole cleaning process, whether the spray head moves or not, the second motor can always keep a starting state, namely the 3D printing model always keeps a rotating state.
Further, in order to ensure the effect of cleaning the surface of the 3D printing model in each working area, the minimum rotation speed of the 3D printing model in the cleaning process can be determined according to the model complexity, and the 3D printing model is controlled to rotate at the rotation speed when the cleaning is performed. It can be appreciated that the higher the model complexity of the 3D printing model, the slower the rotational speed, and the more the cleaning effect can be ensured.
Of course, in practical application, a model complexity can be determined separately for each operation area of the 3D printing model, and then a corresponding rotation speed is set separately for each operation area, so that more accurate cleaning of the 3D printing model is ensured.
When the spray head cleans each working area of the 3D printing model, the rotation speed of the 3D printing model and the rotation angle required by each working area of the 3D printing model to be completely cleaned are determined, and then the time required by the completion of cleaning each working area of the 3D printing model can be determined; and determining the minimum cleaning time length of the whole 3D printing model which is completely cleaned for one time according to the number of the divided working areas of the 3D printing model. Thus, the minimum cleaning time can be determined based on the rotational speed and the number of work areas.
In addition, as mentioned above, in the process of cleaning the 3D printing model, there may be various types of cleaning solutions, and for this purpose, in another alternative embodiment of the present application, the method may further include:
after determining the rotation speed, further comprising:
judging whether the types of cleaning liquid which participate in cleaning and correspond to the 3D printing model are at least two;
if so, taking the product of the number of types of cleaning liquid participating in cleaning and the rotation speed as a new rotation speed so that the second motor drives the 3D printing model to rotate at the new rotation speed;
if not, the rotation speed is kept unchanged.
As before, when multiple cleaning fluids are needed to participate in the cleaning, in this embodiment, instead of mixing all the cleaning fluids, each cleaning fluid is independently used to perform a complete cleaning on the 3D printing model. For example, the cleaning liquid participating in the cleaning is alcohol and water, the 3D printing model is cleaned once by alcohol, then the 3D printing model is cleaned once by water, and after the two cleaning liquids are cleaned once respectively, the 3D printing model is cleaned completely.
In addition, as described above, the spray head performs cleaning on each operation area in the process of cleaning the 3D printing model, one cleaning solution is sprayed first when each operation area is cleaned, after the operation area is completely cleaned once, a second cleaning solution is sprayed again, after the operation area is completely cleaned once, the complete cleaning is completed once, and then the spray head is moved to the cleaning position of the next operation area, and the above processes are repeated for cleaning.
Furthermore, it can be appreciated that in order to shorten the cleaning time as much as possible, and to enable the surface of the 3D printing model to be completely cleaned; therefore, when a plurality of cleaning liquids are needed to participate in cleaning, the rotation speed of the 3D printing model can be further increased by corresponding times according to the types of the cleaning liquids, so that the cleaning of various cleaning liquids can be ensured to be carried out once on the basis of not prolonging the minimum cleaning time of each pass.
In addition, as before, the cleaning time determined in the present application in cleaning the 3D printing model may not be an integer multiple of the minimum cleaning time period. Therefore, in practical application, the rotation speed of the 3D printing model can be adjusted according to the input cleaning time. For example, when the determined cleaning time is greater than twice the minimum cleaning time and less than 3 times the minimum cleaning time, at this time, the cleaning time may be divided by 3, a single-pass cleaning time for each time of cleaning the 3D printing model is determined, the time for cleaning the single working area may be determined according to the single-pass time and the number of working areas to be cleaned, and then the rotation speed of the 3D printing model may be determined according to the required rotation angle of the 3D printing model when each working area completes one complete cleaning.
In the above embodiments, the description has been given taking an example in which the 3D printing model is divided into a plurality of job areas in the vertical direction, each of which is a ring-shaped area. In practical application, can also divide the operation region of the strip of a plurality of vertical directions with 3D printing model along its circumferencial direction, at this moment in the cleaning process to each operation region, can be earlier with the injection direction of shower nozzle directional one operation region to drive the vertical direction of shower nozzle and remove by first motor, accomplish the removal of spraying height at least once when the shower nozzle, then drive 3D printing model rotatory specific angle by the second motor for the injection direction of shower nozzle points to next operation region, and so on, also can accomplish the cleaning of 3D printing model. In addition, in practical application, the spray head can be controlled to realize 180-degree rotary spray in the vertical and horizontal directions under the condition that the spray head is kept at a fixed position, so that cleaning spray of different angles at different positions of the 3D printing model is realized, and the high-precision cleaning of certain concave shielding parts in the 3D printing model is ensured. Other cleaning control modes can exist for the spray head and the 3D printing model in the application, and the description is not given in the application.
Based on the above embodiments, for example, to further avoid the situation of insufficient cleaning solution, in another optional embodiment of the present application, before performing spray cleaning on the 3D printing model according to parameters such as a spray speed, a spray height, and the like, the method may further include:
acquiring the liquid level of a containing device of the cleaning liquid;
judging whether the liquid level is greater than or equal to the minimum value of the liquid level;
if not, outputting a prompt that the cleaning liquid contained in the containing device is lower than the minimum liquid level value.
In order to ensure sufficient cleaning liquid, the liquid level of the cleaning liquid can be detected before the cleaning is started, so that the amount of the residual cleaning liquid is judged, and when the liquid level is too low, the cleaning liquid is likely to be insufficient, and then a worker can be prompted to timely add new cleaning liquid.
If the liquid level is smaller than the liquid level minimum value, outputting a prompt that the cleaning liquid contained in the containing device is lower than the liquid level minimum value, which can include:
when the liquid level is smaller than the minimum liquid level, counting the number of times of acquiring the liquid level;
judging whether the number of times of acquiring the liquid level is larger than a threshold value;
if not, returning to the step of acquiring the liquid level of the containing device of the cleaning liquid;
if yes, outputting a prompt that the cleaning liquid contained in the cleaning liquid containing device is lower than the minimum liquid level.
Of course, in order to avoid the error of the obtained liquid level, the liquid level of the cleaning liquid can be acquired again when the liquid level is determined to be smaller than or equal to the liquid level minimum value, whether the liquid level is larger than the liquid level minimum value is repeatedly judged, if the liquid level is continuously judged to be not larger than the liquid level minimum value for multiple times, the current residual quantity of the cleaning liquid can be determined to be insufficient, and then a worker can be prompted to timely add new cleaning liquid.
