In view of this, an embodiment of a first aspect of the present application provides a control method of a 3D printing apparatus based on the foregoing embodiment, and as shown in fig. 5, the control method of the 3D printing apparatus includes:
s502: and acquiring a signal value when the driving assembly runs.
Wherein the driving component comprises an X-axis driving part, a Y-axis driving part and a Z-axis driving part, the signal value of the driving component during operation, may be some parameter of the drive assembly during operation, such as the output force, electrical signal, power, or other parameter that meets the requirements of the motor during operation of the drive assembly, the signal value of the drive assembly during operation is a specific value of an operating parameter of the drive assembly during operation, wherein the signal value of the driving component during operation can represent the current motion state of the driving component, such as the output force of the operation parameter, when the output force of the driving component is larger, the driving component works abnormally, the printing head possibly scrapes and hits the printing platform, or, if the operating parameter is current or voltage, when the current or voltage of the driving component is larger, it indicates that the driving component is working abnormally, and the printing head may scrape against the printing platform. Therefore, by acquiring the signal value of the driving assembly during operation, whether the current working state of the driving assembly is abnormal or not is conveniently judged.
S504: confirming that the print head is in contact with the printing platform or that the print head collides with the printing platform based on the signal value being greater than or equal to the first set threshold value.
The first set threshold is used for representing a signal value output by the driving assembly when the driving assembly drives the printing head to contact with the printing platform or the printing head collides with the printing platform, namely, when the signal value is greater than or equal to the first set threshold, the printing head is indicated to contact with or collide with the printing platform. If the printing head contacts the printing platform when the model is printed, although the acting force between the printing head and the printing platform is smaller than the force when the printing head collides with the printing platform, the printing head and the printing platform may not be damaged, but because no gap exists between the printing head and the printing platform, a certain acting force also exists between the printing head and the printing platform, consumables sprayed by the printing head cannot be normally formed on the printing platform, and printing failure is easily caused; if the print head hits the print platform, the force between the two is large, which may cause damage to the print head or the print platform. The efficiency and the accuracy of confirming whether the printing head collides with the printing platform can be improved through the signal value output by the driving assembly during operation and the first set threshold value.
Specifically, when the signal value is equal to a first set threshold value, it may be confirmed that the print head is in contact with the printing platform, and when the signal value is greater than the first preset threshold value, it may be confirmed that the print head collides with the printing platform.
Specifically, the first set threshold may be a range or a specific value, where when the first set threshold is a specific value, the first set threshold may be one specific value or several specific values, and the specific limitation manner of the first set threshold is not specifically limited in this application.
Therefore, according to the embodiment provided by the application, by acquiring the signal value of the driving assembly during operation, when the signal value is greater than or equal to the first set threshold value, the position relationship between the printing head and the printing platform can be confirmed, so that the automatic confirmation that the printing head is in contact with the printing platform or the printing head hits the printing platform is realized, compared with the prior art that a user confirms that the printing head is in contact with the printing platform or the printing head hits the printing platform by eyes, the method is beneficial to improving the timeliness and the accuracy of the confirmation, further beneficial to reducing the damage degree of the printing head or the printing platform, reducing the fault rate of equipment, improving the reliability of a product, and the method for confirming that the printing head hits the printing platform is simple, high in accuracy, no additional element is needed, and the cost of the 3D printing equipment is reduced.
In the above embodiment, acquiring the signal value of the driving component during operation may include: and acquiring a voltage value or a current value when the driving component operates.
The method is simple to control and easy to realize, and is favorable for improving the accuracy and reliability of confirming that the printing head is in contact with the printing platform or the printing head collides with the printing platform, and the printing head and the printing platform are well protected. In the specific embodiment provided by the present application, taking the current value obtained when the driving component operates as an example, the current is a current value of a motor of the driving component, and specifically, may be at least one of a current value of a first motor of the X-axis driving portion, a current value of a second motor of the Y-axis driving portion, and a current value of a third motor of the Z-axis driving portion. The printing head is provided with a nozzle, when the nozzle of the printing head is contacted with the printing platform, certain friction force is applied to the X-axis direction and the Y-axis direction, when the printing head and the printing platform are close to each other, the resistance of the Z-axis is larger, the printing head is taken as an example relative to the printing platform along the X-axis direction, at the moment, the printing head generates friction force between the printing head and the printing platform when moving in the X-axis direction, namely, the first motor of the X-axis driving part needs to output not only the force for driving the printing head to operate, but also the friction force between the printing head and the printing platform.
If the output operation force of the first motor of the X-axis driving portion is set, for example, the set output force of the first motor of the X-axis driving portion is FX, and the signal value output by the output force FX corresponding to the first set threshold value is set. The force of the first motor of the X-axis driving part driving the print head to move relative to the print platform without contacting the print platform is FX1, the friction force of the first motor of the X-axis driving part when the print head contacts the print platform is FX2, and the total output force of the first motor of the X-axis driving part driving the print head to move relative to the print platform and contact the print platform is FX3, that is, FX3 is FX1+ FX 2. If FX3 is greater than or equal to FX, it indicates that the print head is in contact with the print platform or that the print head impacts the print platform.
The resistance R of the motor is kept constant, and the current I or the voltage V changes with the force applied, that is, the current signal value or the voltage signal value of the first motor of the X-axis driving portion changes with the output force of the corresponding motor. The present application takes the current signal value as an example for explanation. Specifically, the threshold current preset by the first motor of the X-axis driving part is IX, that is, the first set threshold is IX; the current value output when the first motor of the X-axis drive unit is actually operated is IX 2. When the current value IX2 of the first motor at which the X-axis drive section operates is larger than the first set threshold IX, the system regards that the print head has contacted or collided with the print table at this time. Therefore, the judgment and confirmation that the printing head is contacted with the printing platform or the printing head collides with the printing platform can be realized by comparing the acquired current value when the driving assembly operates with the corresponding first set threshold value.
It can be understood that, based on the same principle as above, the system can automatically confirm the contact or collision between the print head and the print platform when the print head moves along the Z-axis direction, and the system can automatically confirm the contact or collision between the print head and the print platform when the print platform moves along the Y-axis direction, which is not described herein again.
In the embodiment provided by the application, the driving coil is arranged in the driving assembly, and the driving assembly is enabled to work by supplying power to the driving coil, that is, electric energy is converted into driving force of the driving assembly, so that obtaining a signal value when the driving assembly operates means obtaining a signal value output by the driving coil when the driving assembly operates, and the signal value may be a voltage value or a current value. Taking the signal value as an example of the current value, when the driving assembly operates, the larger the force required to drive the print head or the print platform to move, the larger the current value supplied to the driving coil, so that when the print head collides with the print platform, the current value in the driving coil is increased in order to enable the print head or the print platform to move. Therefore, whether the printing head and the printing platform contact or collide can be detected by reasonably setting the first setting threshold.
In some possible implementation embodiments provided herein, after acquiring the signal value of the driving component at runtime, the control method of the 3D printing apparatus further includes:
s506: driving the print head away from the print platform or driving the print platform away from the print head based on the signal value being greater than or equal to the first set threshold.
In this embodiment, when the signal value is greater than or equal to the first set threshold, it can be determined that the print head contacts the print platform or the print head collides with the print platform, and therefore the control device controls the driving assembly to drive the print head to be away from the print platform, so that the print head is away from the print platform, and the effect of protecting the print head and the print platform is achieved, and the situation that the print head is damaged and/or the print platform is damaged due to continuous contact of the print head and the print platform can be avoided, thereby being beneficial to prolonging the service lives of the print head and the print platform, and improving the reliability of the 3D printing device.
In some possible embodiments, when the signal value is greater than or equal to the first set threshold, it may also be that the print head hits the model, for example, the print head hits a part of the model that is already completed and solidified, so that the print head is driven to be away from the model, the print head is separated from the model, the print head and the model are protected, the situation that the print head is damaged or the model is damaged due to the fact that the print head continuously hits the model can be avoided, the service life of the print head is prolonged, and the damage degree of the model is reduced. Meanwhile, the process does not need manual participation, the operation that the printing head is separated from the model by automatically controlling the driving assembly is realized, compared with manual adjustment, manual operation is simplified, and the operation experience of a user is improved.
Furthermore, after the printing head is separated from the printing platform or the printing head is separated from the model, the position of the printing head relative to the printing platform or the printing head relative to the model is readjusted, so that good printing quality can be ensured, smooth printing can be ensured, and the using satisfaction of a user is improved.
Wherein, based on the signal value being greater than or equal to the first set threshold, driving the print head away from the print platform, or driving the print platform away from the print head, includes:
driving the printing head to move a unit distance in a direction away from the printing platform or driving the printing platform to move a unit distance in a direction away from the printing head, and comparing a signal value output by the driving assembly with a first set threshold value; if the signal value is smaller than a first set threshold value, stopping driving and recording three-dimensional coordinate information; if the signal value is larger than or equal to the first set threshold value, the step of driving the printing head to move towards the direction far away from the printing platform or driving the printing platform to move towards the direction far away from the printing head by a unit distance is repeatedly executed, and the signal value output by the driving assembly is compared with the first set threshold value until the signal value is smaller than the first set threshold value.
It will be understood that the unit distance is the minimum distance that the drive assembly drives the print head in the Z-axis. When the 3D printing equipment prints the model, the printing head can slightly move and slightly deflect at a plurality of angles to adapt to different spraying scenes, so that the printing head is often connected with an elastic piece, and the printing head can move during working. The printing head is arranged in front of the first layer of the printing model, and the elastic piece is slightly deformed towards one side close to the printing head under the gravity of the printing head; if the printing head collides with the printing platform, the force applied by the printing head to the elastic element deforms the elastic element towards the side away from the printing head, so that the printing head and the printing platform can be separated if the driving assembly only drives the printing head or the printing platform to move for a unit distance.
