Description

Technical Field

[0001] This invention relates to the field of industrial printing, and in particular to an automatic control method, apparatus and equipment for a suction platform. Background Technology

[0002] Most flatbed inkjet printers and some photo printers have a suction platform installed on the machine to create negative pressure to attract the printing media, improving print quality and preventing the media from scraping the print head as the print carriage moves. Currently, many flatbed printers use a manual control scheme, with the suction platform independent of the printing system. When the machine is printing or the print carriage is moving into the media's range, the user needs to manually open the suction platform; the printing system does not automatically activate the suction. If the user forgets to open the suction platform and the printing media protrudes above the print head, it will scrape the print head, contaminating the material and damaging the print head.

[0049] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the invention.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0051] Example 1

[0052] Please see Figure 1 This invention provides an automatic control method for a suction platform, characterized in that the method includes:

[0053] S1: Obtain printing media size information and printing media position information;

[0054] S2: Determine the printing media range based on the printing media size information and the printing media position information;

[0055] S3: When there is no printing task, the suction platform is turned on before the printing carriage enters the printing medium range, and the suction platform is turned off after the printing carriage has completely moved out of the printing medium range.

[0056] S4: When there is a printing task, control the suction platform to turn on before executing the printing task, and control the suction platform to turn off after the printing task ends or is canceled and the printing carriage returns to the origin.

[0057] Specifically, the system first acquires the size and position information of the printing medium. The size information can be obtained by automatically measuring the paper during material placement or by manually inputting the size. The position information can be accurately located using machine vision. Based on the position and size information, the range of the printing medium on the printing platform can be determined. When there is no printing task but the printing carriage moves, the user manually controls the carriage to move. The suction platform is activated when the carriage is about to enter the range of the printing medium, and deactivated when the carriage has completely moved out of the range. When there is a printing task, the suction platform is activated before the task is executed and deactivated after the task is completed or canceled and the carriage returns to its origin. The origin is the default position of the printing carriage when no printing task is being executed.

[0058] In one embodiment, a two-dimensional planar coordinate system is established on the suction platform, with the moving direction of the printing carriage as the X-axis and the stepping direction of the printing medium as the Y-axis. Step S3 specifically includes:

[0059] S31: Determine the coordinate information of the printing media range based on the printing media size information and the printing media position information;

[0060] S32: Obtain the real-time coordinate information of the printing cart;

[0061] S33: Based on the coordinate information of the printing medium range and the real-time coordinate information of the printing carriage, determine the relative distance between the printing carriage and the printing medium in the direction of movement of the printing carriage;

[0062] S34: When the relative distance is equal to the first preset value, control the suction platform to operate at rated power;

[0063] S35: After the printing carriage has completely moved out of the printing medium range, control the suction platform to shut down.

[0064] Specifically, a two-dimensional planar coordinate system is first established on the suction platform or printing platform. The two-dimensional planar coordinate system has the moving direction of the printing carriage as the X-axis and the direction perpendicular to the X-axis (i.e., the stepping direction of the printing medium) as the Y-axis. The coordinate information of the printing medium range is determined based on the printing medium size information and the printing medium position information. Then, the coordinate information of the printing carriage is acquired in real time. The relative distance between the printing carriage and the printing medium is determined based on the coordinate information of the printing medium range and the real-time acquired coordinate information of the printing carriage. When the relative distance is less than or equal to a first preset value, the suction platform is controlled to start running at rated power. The first preset value can be set automatically according to the moving speed of the printing carriage and the time required for the suction platform to fully start, ensuring that the suction platform has started running at rated power when the printing carriage enters the printing medium range, preventing the situation where the suction platform has not yet started when the printing carriage enters the printing medium range, and preventing the printing medium and the printing carriage from scratching.

[0065] In one embodiment, when the printing medium is a rectangular printing medium, the coordinate information of the printing medium range includes the coordinate information of all vertices of the rectangular printing medium, respectively denoted as the first vertex coordinate information, the second vertex coordinate information, the third vertex coordinate information, and the fourth vertex coordinate information. Step S33 specifically includes:

[0066] S331: Based on the coordinate information of all the vertices, determine the angle between the rectangular printing medium and the X-axis;

[0067] S332: When the included angle is less than or equal to 0°, the difference between the abscissa value of the first vertex coordinate information and the abscissa value of the real-time coordinate information of the printing trolley is used as the relative spacing;

[0068] S333: When the included angle is greater than 0°, the difference between the horizontal coordinate value of the third vertex coordinate information and the horizontal coordinate value of the real-time coordinate information of the printing trolley is used as the relative spacing.

[0069] Specifically, when the printing medium is rectangular, the printing medium's area can be determined by its four vertices, reducing data processing volume and improving efficiency. After obtaining the coordinates of each vertex, the angle between the rectangular printing medium and the X-axis is determined based on these coordinates. See [link to relevant documentation]. Figure 2a At this point, the angle between the rectangular printing medium and the X-axis is 0°. The difference between the x-coordinate value of the first vertex coordinate information and the x-coordinate value of the real-time coordinate information of the printing carriage is used as the relative spacing; see [link to relevant documentation]. Figure 2bAt this point, the angle between the rectangular printing medium and the X-axis is less than 0°, and the first vertex is the vertex closest to the printing carriage. The difference between the x-coordinate of the first vertex and the x-coordinate of the real-time printing carriage is then used as the relative spacing. (See also...) Figure 2c At this time, the angle between the rectangular printing medium and the X-axis is greater than 0°, and the third vertex is the vertex closest to the printing carriage. The difference between the horizontal coordinate value of the third vertex coordinate information and the horizontal coordinate value of the real-time coordinate information of the printing carriage is used as the relative spacing.

[0070] In one embodiment, when the printing medium is not a rectangular printing medium, the coordinate information of the printing medium range includes the coordinate information of each point on the outline of the printing medium, and step S33 includes:

[0071] S334: Based on the real-time coordinate information of the printing carriage, determine the point on the outline of the printing medium that is closest to the nozzle, and record it as the nearest point;

[0072] S335: The difference between the x-coordinate value of the nearest point and the x-coordinate value of the real-time coordinate information of the printing trolley is taken as the relative distance.

[0073] Specifically, when the printing medium is a shape other than a rectangle, such as a circle, ellipse, triangle, or other irregular shape, the coordinate information of the printing medium range includes the coordinate information of each point on the outline of the printing medium. First, the point closest to the printhead is determined among all the outline points and denoted as the nearest point. Then, the relative distance is the difference between the horizontal coordinate value of the nearest point and the horizontal coordinate value of the real-time coordinate information of the printing carriage.

[0074] In one embodiment, when the printing medium is a rectangular printing medium, step S35 specifically includes:

[0075] S351: When the included angle is greater than or equal to 0° and the horizontal coordinate value of the real-time coordinate information of the printing trolley is greater than the horizontal coordinate of the second vertex, control the suction platform to shut down;

[0076] S352: When the included angle is less than 0° and the horizontal coordinate value of the real-time coordinate information of the printing trolley is greater than the horizontal coordinate of the fourth vertex, control the suction platform to shut down.

[0077] Specifically, when the printing medium is a rectangular printing medium, if the included angle is greater than or equal to 0° and the horizontal coordinate value of the real-time coordinate information of the printing carriage is greater than the horizontal coordinate of the second vertex, then it is considered that the printing carriage has completely left the range of the printing medium, and the suction platform is controlled to close. If the included angle is less than 0° and the horizontal coordinate value of the real-time coordinate information of the printing carriage is greater than the horizontal coordinate of the fourth vertex, then it is considered that the printing carriage has completely left the range of the printing medium, and the suction platform is controlled to close.

[0078] In one embodiment, when the printing medium is not a rectangular printing medium, step S35 includes:

[0079] S353: Based on the real-time coordinate information of the printing carriage, determine the point on the outline of the printing medium that is farthest from the nozzle, and record it as the farthest point.

[0080] S354: When the horizontal coordinate value of the real-time coordinate information of the printing trolley is greater than or equal to the horizontal coordinate of the farthest point, control the suction platform to shut down.

[0081] Specifically, when the printing medium is not a rectangular printing medium, based on the real-time coordinate information of the printing carriage, the point farthest from the nozzle among all points on the outline of the printing medium is determined and recorded as the farthest point. When the horizontal coordinate value of the real-time coordinate information of the printing carriage is greater than or equal to the horizontal coordinate of the farthest point, it is considered that the printing carriage has left the printing medium range, and at this time the suction platform is controlled to close.

[0082] In one embodiment, step S4 includes:

[0083] S41: Obtain print data or ink parameters;

[0084] S42: Determine the operating power of the suction platform based on the printed data or the ink parameters;

[0085] S43: Before printing, control the suction platform to turn on according to the operating power;

[0086] S44: After printing ends or is canceled and the printing carriage returns to its origin, control the suction platform to shut down.

[0087] Specifically, firstly, printing data or ink parameters are acquired. Based on the printing data or ink parameters, the operating power of the suction platform is determined. Before printing, the suction platform is controlled to turn on according to the operating power. After printing ends or is canceled and the printing carriage returns to its origin, the suction platform is controlled to turn off. In one embodiment, the ink used for printing includes a first type of ink and a second type of ink. The ink parameters include ink permeability. When the ink permeability of the first type of ink is greater than that of the second type of ink, if the same suction power is used, it cannot be guaranteed that each type of ink can fully penetrate and level. Even if the suction power is high enough to guarantee that each type of ink can fully penetrate and level, it is still not guaranteed. However, this would waste energy and not meet the current requirements for energy conservation and carbon reduction. Therefore, the power of the suction platform is set according to the ink parameters of different inks. In another embodiment, only the printing data is obtained in step S41. The actual number of passes printed can be determined based on the printing data. When multiple passes are used for printing, the ink volume and number of coverages of different passes are different, resulting in different ink leveling and penetration. If the same suction power is used, the printing effect of the first pass and the last pass will be different, affecting the final printing effect. Therefore, the ink volume of each pass is determined according to the printing data, and the operating power of the suction platform is determined according to the ink volume of each pass, which can achieve better printing effect.

[0088] In another embodiment, after step S42, step S4 further includes:

[0089] S421: Obtain the vertical distance between the printing medium and the printing carriage, and record it as the vertical distance;

[0090] S422: When the vertical distance is less than the preset vertical distance, increase the operating power by a first preset value;

[0091] Specifically, firstly, the vertical distance between the printing medium and the printing carriage is obtained and denoted as the vertical distance. The vertical distance can be measured using a ruler or by a distance sensor installed on the printing carriage; no specific limitation is made here. When the vertical distance is less than a preset vertical distance, to avoid the printing medium not being able to be smoothly adsorbed due to insufficient operating power of the suction platform, after determining the operating power of the suction platform based on the printing data or ink parameters, the operating power is increased by a first preset value. The first preset value can be set by the user according to the actual situation of the inkjet printing equipment; no restriction is made here. By increasing the operating power by the first preset value, it is possible to ensure that if the vertical distance between the printing carriage and the printing medium is too small, the risk of the printhead being scratched due to uneven printing medium is avoided, thus extending the life of the printhead and reducing costs.

[0092] The automatic control method for the suction platform provided in this invention obtains printing media size information and printing media position information; determines the printing media range based on the printing media size information and printing media position information; when there is no printing task, the suction platform is controlled to open before the printing carriage enters the printing media range, and the suction platform is controlled to close after the printing carriage has completely moved out of the printing media range; when there is a printing task, the suction platform is controlled to open before the printing task is executed, and the suction platform is controlled to close after the printing task is completed or canceled and the printing carriage returns to its original position. This allows the suction platform to be fully automatically controlled by the printing system, eliminating the risk of printhead scratches caused by users forgetting to open the suction platform before printing or moving the printing carriage, and improving the automation level of the entire printing system.

[0098] The second control device is used to control the suction platform to turn on before the printing task is executed when there is a printing task, and to control the suction platform to turn off after the printing task is completed or canceled and the printing carriage returns to the origin.
