Fig. 1 is a flowchart illustrating a method for moving a spray head according to an embodiment of the present application, where the method includes the following steps, as shown in fig. 1:
Specifically, the target image is an image to be printed received by the printer, and the printing area is a printing medium provided for the printer to print the target image, such as paper, a plate material, a device, and other specific entities. The content line is divided according to an ink ejection width that can be achieved by a head of the printer. After dividing the content lines in the target image, acquiring the head end and the tail end of each content line, and regarding the unidirectional printing, taking the head end of each content line as the starting point of the content line and the tail end of each content line as the end point of the content line; for bidirectional printing, sequencing each content line according to the sequence of the content line in a target image, and if the sequence of the content line is an odd number, taking the head end of the content line as the starting point of the content line and the tail end of the content line as the end point of the content line; if the content line is ordered in an even number, the end of the content line is used as the start point of the content line, and the head end of the content line is used as the end point of the content line.
Specifically, the printer controls the nozzle to print in the printing area, and the abscissa and the ordinate of the nozzle corresponding to the printing area are actually the abscissa and the ordinate corresponding to the center of the orthographic projection of the nozzle on the first nozzle hole of the printing area; and taking the abscissa of the orthographic projection of the first spray hole of the spray head as a first transverse position, and taking the ordinate of the orthographic projection of the first spray hole of the spray head as a first longitudinal position. The printing area and the spray head keep relative movement, when the printing area moves and the spray head keeps still, the ordinate of the spray head in the printing area can be changed, and when the spray head moves and the printing area keeps still, the abscissa of the spray head in the printing area can be changed. And for each content line, after the start coordinate corresponding to the starting point of the content line is determined, the abscissa and the ordinate of the spray head corresponding to the printing area are determined again.
103, controlling the printing area to move longitudinally during controlling the spray head to move from the first transverse position to a second transverse position corresponding to the abscissa of the target starting coordinate, so as to move the spray head from a first longitudinal position in the printing area to a second longitudinal position corresponding to the ordinate of the target starting coordinate; the target start coordinate is the start coordinate of the content line.
Specifically, for each content line, before printing, after determining the first transverse position and the first longitudinal position of the nozzle currently in the printing area according to step 102, when the nozzle moves in the transverse position of the printing area, the nozzle moves from the first transverse position to the second transverse position; at this time, the printing area is controlled to move longitudinally such that the head moves from a first longitudinal position to a second longitudinal position of the printing area.
The method for moving the spray head comprises the steps of obtaining a starting coordinate corresponding to a starting point of each content line in a target image in a printing area; the width of the content line is the ink jetting width of the nozzle in the printing area; for each content line, determining an abscissa and an ordinate of the nozzle corresponding to the content line in the printing area, so as to respectively use the abscissa and the ordinate as a first transverse position and a first longitudinal position of the nozzle corresponding to the printing area; controlling the printing area to move longitudinally during controlling the spray head to move from the first transverse position to a second transverse position corresponding to the abscissa of the target starting coordinate, so as to move the spray head from a first longitudinal position in the printing area to a second longitudinal position corresponding to the ordinate of the target starting coordinate; the target start coordinate is the start coordinate of the content line. By the method, the printing area can be moved longitudinally at the same time in the process that the spray head moves transversely to the abscissa of the starting coordinate corresponding to the starting point of the content line, and compared with the scheme that the spray head is moved firstly and then the printing area is moved in the prior art, the method can control the spray head to be close to the starting coordinate corresponding to the starting point of the content line in the transverse direction and the longitudinal direction at the same time, and can improve the moving efficiency of the spray head on the printing area.
In a possible implementation, fig. 2 shows a flowchart of a method for adjusting a moving speed provided by an embodiment of the present application, after the step 102 is executed to determine, for each content line, an abscissa and an ordinate of the inkjet head corresponding to the content line in the printing area, the method further includes the following steps:
Specifically, the content line refers to the content line corresponding to the target start coordinate in step 103, for each content line, the length, the start point, and the end point of each content line can be determined by the target image, and after the target start coordinate of the content line in the print area is determined, the target end coordinate of the content line corresponding to the print area is determined according to the end point of the content line.
Specifically, after the target end coordinates corresponding to the content line in the printing area are acquired, the inkjet head is controlled to shift from a stationary position to a second transverse position at the first transverse position, and the embodiment of the present application is not limited to the shifting method, and specific shifting methods include, but are not limited to:
when the direction of movement of the spray head from the first lateral position to the second lateral position is the same as the direction of the first velocity:
(1) controlling the spray head to accelerate from a rest state to a preset maximum spray head speed at a first transverse position, and then decelerating from the maximum spray head speed to a first speed; the moving direction of the spray head is not changed.
(2) Controlling the spray head to accelerate from a rest starting position to a second transverse position at the first transverse position, so that the speed of the spray head is accelerated from 0 to the first speed when the spray head reaches the second transverse position; the moving direction of the spray head is not changed.
When the direction of movement of the spray head from the first lateral position to the second lateral position is opposite to the direction of the first velocity:
(3) controlling the spray head to accelerate from rest to a preset maximum spray head speed at a first transverse position, then decelerating from the preset maximum spray head speed to 0, and reaching a third transverse position; the first lateral position points in the same direction as the direction of movement of the spray head to the third lateral position.
Controlling the spray head to move from the third transverse position to the second transverse position in an accelerating way, so that the speed of the spray head is accelerated from 0 to the first speed when the spray head reaches the second transverse position; the third lateral position points in the same direction as the first velocity at the second lateral position.
The first speed is an ink jetting speed preset for the printer before printing, so that the printer moves from a target start coordinate of a printing area to a target end coordinate of the printing area according to the ink jetting speed, and an ink jetting process is guaranteed by controlling the ink jetting speed.
In one possible embodiment, when step 103 is executed to control the printing area to move longitudinally to move the nozzle from a first longitudinal position in the printing area to a second longitudinal position corresponding to the ordinate of the target start coordinate, the method includes the following steps:
step 211, adjusting the moving speed of the printing area to move the nozzle from the first longitudinal position in the printing area to the second longitudinal position corresponding to the ordinate of the target start coordinate before the nozzle moves to the second lateral position.
Specifically, before printing, a moving threshold of a printing area is preset for the printer, and in the process that the spray head moves from a first transverse position to a second transverse position, the printing area is controlled to move at a speed not exceeding the moving threshold; conversely, when the actual movement distance between the first transverse position and the second transverse position is longer, the movement speed is adaptively slowed down according to the actual movement distance between the first longitudinal position and the second longitudinal position, so that the movement of the printing area can be completed before the head moves to the second transverse position.
It should be noted that, in this embodiment of the present application, the arrival order of the nozzles and the printing area is not limited, and in another possible implementation, the movement speed of the printing area may also be adjusted so that the printing area and the nozzles complete movement at the same time; alternatively, the head is controlled to complete the movement from the first lateral position to the second lateral position before the movement of the printing area is completed. The moving method of the moving area is similar to the moving method of the nozzle in step 202, and is not described herein again.
In one possible embodiment, when the method performs step 202 to control the sprinkler to move from the first lateral position to the second lateral position at a variable speed such that the sprinkler reaches the second lateral position at a first speed, the method includes the steps of:
in step 212, a preset ink ejection speed is determined as the value of the first speed.
Specifically, an ink ejection speed preset for the printer is acquired, and the value of the ink ejection speed is determined as the value of the first speed.
And 213, adjusting the speed and/or acceleration of the spray head moving from the first transverse position to the second transverse position according to the value of the first speed, so that the average speed of the spray head moving from the first transverse position to the second transverse position is greater than the first speed.
Specifically, after determining the value of the first speed according to step 212, an average speed is obtained from the actual distance traveled by the spray head and the actual time according to the value of the first speed, and the speed of the spray head during its movement from the first lateral position to the second lateral position is adjusted such that the average speed is greater than the first speed.
By the method, the printer can quickly skip the blank position of the target image corresponding to the printing area and quickly move to the starting position of the printing area corresponding to the starting point of the content line, and the printing speed and efficiency are improved.
In one possible embodiment, after the showerhead reaches the second lateral position at the first velocity in step 202, the method further comprises the steps of:
determining the position coordinate of the spray head corresponding to the printing area at present; when the position coordinate is the same as the target starting coordinate, controlling the spray head to move at a constant speed from the target starting coordinate to the target ending coordinate at the first speed; and the nozzle performs ink jet in the process of moving from the target start coordinate to the target end coordinate at a constant speed.
Specifically, after the nozzle reaches the second transverse position, as shown in step 211, the printing area has been changed from the first longitudinal position to the second longitudinal position in the printing area by the longitudinal movement, that is, the abscissa and the ordinate of the nozzle are the second transverse position and the second longitudinal position respectively; and if the position coordinate is the same as the target starting coordinate, controlling the spray head to spray ink at a constant speed according to the first speed, spraying the content of the content line in the target image to the printing area, and generating printing data according to the starting point and the end point of the content line by the printer.
It should be noted that, after the nozzle moves to the target end position corresponding to the content line in the printing area at the first speed, stopping jetting ink, and determining that the content line is completely printed; the next content line continues to be printed until all content lines in the entire target image have been printed in the print area. The printing sequence of the content lines may be arranged according to the sequence of each content line in the target image, or may be preset.
